The invention discloses a disassembling clamp for an MMCX connector. The disassembling clamp comprises a left clamp unit, a right clamp unit, a rotary connecting shaft and a reset spring, wherein the left clamp unit and the right clamp unit are oppositely arranged and rotatably connected through the rotary connecting shaft. By means of the mode, the disassembling clamp for the MMCX connector can disassemble the MMCX connector easily and smoothly under the condition that a board and elements are not damaged, so that scrapping is avoided, the operation difficulty of an operator is lowered, and the working efficiency is improved.

The invention provides a method for manufacturing a motor rotor and a self-aligning positioning mechanism used thereby. The method for manufacturing the motor rotor is characterized in that the motor rotor is formed by splicing a mandrel and magnetic steel by the self-aligning positioning mechanism through binding agent. The self-aligning positioning mechanism consists of a locating column, an aligning rod, an outer sleeve, a spring and a regulating rod, wherein the locating column contains a locating hole, communicating grooves are arranged around the upper part of the aligning rod, the sideof the aligning rod at the communicating grooves is a reversed-V-shaped conical surface which is matched with a corresponding reversed-V-shaped conical surface at the upper part of an inner cavity ofthe outer sleeve, and the lower part of the aligning rod is provided with a transverse through hole that is in clearance fit with a pressure bar; the outer sleeve is provided with an inner hole whichis in clearance fit with the aligning rod, the two sides of the outer sleeve are symmetrically provided with two long grooves, the pressure bar is inserted into the inner hole of the aligning rod andcan move up and down inside the two long grooves, the lower part of the outer sleeve is matched with the regulating rod by screw thread, and the spring is arranged between the aligning rod and the regulating rod. The invention has the advantages of greatly improving the accuracy of product and manufacturing efficiency as well as reducing the manufacturing cost of the product.

The invention provides a double-blade boring cutter head without radial motion for a cutter bar, aiming to provide a stable and reliable boring cutter head capable of reducing the self-excited vibration of a boring bar. The double-blade boring cutter head comprises a cutter base which is fixedly connected to the end head of a boring bar (4) and can be used for replacing a blade; and the cutter base comprises two symmetrical crescent base bodies in a shear fork shape, wherein end part same-hole shafts of the two symmetrical crescent base bodies can be rotatably connected to a sunken platform of a push rod (2) and the boring bar (4). Since the two symmetrical crescent base bodies in a shear fork shape are used, the cutter bar does not do radial motion but can realize self-radial feeding in the boring and cutting process. By the invention, radial cutting forces of two blades on the boring cutter head can be mutually offset, so that asymmetrical unidirectional forced condition of the cutter bar can be changed; and the boring bar is not a cantilever beam single side of which is forced any longer and cannot generate the phenomena of deviation of blade center, cutter relieving or cutter scraping like a single-blade boring cutter.

The invention discloses an exposure method for controlling the difference in line width of flexible circuit board batches. length value, the meter number counter feeds this signal back to the main controller; 3 the main controller generates a new signal after processing and transmits it to the exposure energy controller; 4 after the exposure energy controller receives the signal from the main controller, Control the amount of exposure light for the length of the next stage of the flexible circuit board; 5 repeat steps 1 to 4 until the exposure of all flexible circuit boards is completed. The invention weakens the diffusion of the photoresist by controlling the exposure energy, so as to control the deviation of the circuit due to the different time from exposure to development.

The invention discloses a tooling device for pressure testing of high-pressure oil pipes, which includes a left oil pipe fixing assembly, a right oil pipe fixing assembly, a bottom plate, a water inlet pipe, an air inlet pipe, and a connecting water pipe, wherein the left oil pipe fixing assembly includes a first hand valve, The first plug, the baffle plate, the swivel seat, the first air pipe, the second air pipe, and the oil pipe fixing assembly on the right side include the second plug, the third plug, the third air pipe, the fourth air pipe, and the second hand valve. The invention makes the first plug and the third plug pinch the joints at both ends of the high-pressure oil pipe under the push of the piston rod by turning the first hand valve and the second hand valve. The operation is simple and convenient, and the length of the high-pressure oil pipe is different. It is easy to install by adjusting the screw rod to reach a suitable distance. Use the rotation of the rotating seat to adjust the angle of the groove on the baffle to make it easy to install the oil pipe. Adjust the distance and angle by sliding the splint on the connecting rod to achieve The orientation adjustment of the left oil pipe fixing assembly and the right oil pipe fixing assembly.
