The invention provides a positioning device. A rotation space is arranged on one side of a penetrating hole in a sleeve. A limiting ring body is arranged at the top of the outer side of the sleeve. Afirst limiting slot, two second limiting slots and a convex ring between the two second limiting slots are arranged on the outer edge of the limiting ring body. A positioning element penetrating intothe penetrating hole and an elastic element arranged on the positioning element in a sleeving mode are arranged on the bottom surface of a rod head of a rotary buckling element outside the sleeve. Therod head is positioned in an assembling space of a driving sleeve body. A long convex rod and two short convex rods corresponding to the first limiting slot and the two second limiting slots respectively are arranged in a sliding inner hole formed in the one side of the assembling space and covering the limiting ring body. During locking operation, the driving sleeve body can rotate in two directions. But during unlocking operation, the driving sleeve body can only rotate in one direction. Therefore, the purpose of easily recognizing the locking or unlocking state through different operationhand feelings is realized.

The invention discloses a batch machining workbench suitable for a CNC machine tool. The batch machining workbench comprises a workpiece positioning and placing plate and a machine tool connecting seat. The workpiece positioning and placing plate is fixedly connected with the upper surface of the machine tool connecting seat. A plurality of cavities used for containing workpieces are evenly formedin the upper surface of the workpiece positioning and placing plate at intervals in sequence. A plurality of taking grooves are annularly formed in outer rings of the cavities. Feeding inclined planes are arranged on the inner walls of the cavities. The invention further discloses a detection machining method implemented based on the batch machining workbench suitable for the CNC machine tool. The batch machining workbench is reasonable and ingenious in structural design. Errors caused by the floating of the sizes of the workpieces are reduced as much as possible. The quality of products is improved. The detection machining method is suitable for the detection machining of most workpieces arranged equidistantly. The reject ratio is reduced. Cavities without workpieces are prevented from being detected. The flexibility is good. The working time is shortened. The cost is saved. The cavities with no workpieces are not machined repeatedly. The working efficiency is improved.

The invention discloses a safety fool-proof device for workpiece processing of a numerical control machine tool, which comprises a mounting plate and mounting holes arranged on four sides of the mounting plate, support frames are symmetrically installed on the other two sides of the mounting plate, and one side of the support frame is evenly provided with Sliding holes, the limit pins are interspersed in the sliding holes, one end of the limit pins in the support frame is equipped with a pressure plate, the other side of the support frame is equipped with a fixing plate, and the positions of the fixing plates corresponding to each sliding hole are provided with wires. Hole, the screw hole is threadedly connected to the lead screw, and one end of the lead screw is provided with a rotary plate. By disassembling the fixing plate, it is convenient to replace the spring. Through the anti-fooling limit of the limit pin, the plate-shaped workpiece can only be placed corresponding to the fixed limit pin distance on the left and right sides, so that the plate-shaped workpiece can be stably contacted with the mounting plate. Only one adjustment is needed, and there is no need to re-set the tool, which is safer And high efficiency, good anti-fooling effect, solves the problem in the prior art that there is no anti-fooling effect for clamping plate-shaped workpieces.

The invention provides a positioning device. A rotation space is arranged on one side of a penetrating hole in a sleeve. A limiting ring body is arranged at the top of the outer side of the sleeve. Afirst limiting slot, two second limiting slots and a convex ring between the two second limiting slots are arranged on the outer edge of the limiting ring body. A positioning element penetrating intothe penetrating hole and an elastic element arranged on the positioning element in a sleeving mode are arranged on the bottom surface of a rod head of a rotary buckling element outside the sleeve. Therod head is positioned in an assembling space of a driving sleeve body. A long convex rod and two short convex rods corresponding to the first limiting slot and the two second limiting slots respectively are arranged in a sliding inner hole formed in the one side of the assembling space and covering the limiting ring body. During locking operation, the driving sleeve body can rotate in two directions. But during unlocking operation, the driving sleeve body can only rotate in one direction. Therefore, the purpose of easily recognizing the locking or unlocking state through different operationhand feelings is realized.

The application discloses a light sensor component and an electronic device with the same. The light sensor comprises a main board, a light-sensing device, and a cover body, wherein the light-sensingdevice is arranged on the main board and connected with the main board; N ridges are formed on the peripheral wall of the light-sensing device; a groove extending along the length direction of the ridges of n adjacent ridges, wherein n is more than 0 and not more than N-1; the cover body is covered on the light-sensing device, the inner peripheral wall of the cover body is cooperated with the peripheral wall of the light-sensing device, and a bulge cooperated with the groove is arranged at n adjacent ridges corresponding to the groove on the inner peripheral wall of the cover body, and the bulge extends along the length direction of the ridge of the cover body. According to the light-sensor component disclosed by the application, an operation of reversely installing the cover when the light-sensing device is assembled can be prevented, and good poka-yoke effect is provided. Furthermore, the connection fixation of the cover body and the light-sensing device can be realized through the cooperation of the groove and the bulge, the size of the light-sensor component can be reduced, and the occupied space in the electronic device is reduced.

The invention belongs to the technical field of mortice door locks, and in particular relates to an anti-break mortice door lock head. The anti-break mortice door lock head comprises a lock cylinder shell, a left lock head, a right lock head and a shifting piece, wherein the left lock head and the right lock head are mirror images of each other and installed on the lock cylinder shell; a lock cylinder is installed in the right lock head; the shifting piece is installed between the left lock head and the right lock head and connected with the lock cylinder; an installation groove is formed on the upper part of the lock cylinder shell; an anti-break rod is installed in the installation groove; positioning clamping grooves are formed in the bottom of the installation groove; positioning clamping blocks are arranged at the bottom of the anti-break rod and can be inserted into the positioning clamping grooves; pin tumbler holes are formed in the lock cylinder shell; inner ejector pin tumblers are installed in the pin tumbler holes through springs; and the openings of the pin tumbler holes are positioned at the bottom of the installation groove.
