The invention discloses an assembled rotational conductive module and belongs to the technical field of modular products. The assembled rotational conductive module comprises a structure module, a first PCB, a second PCB and a hinge assembly, wherein a buckle is clamped into a buckle hole in an installation condition; the first PCB and the second PCB sleeve a guide post separately; a first conductive needle is propped against a first conductive channel; a second conductive needle is propped against a second conductive channel; the first PCB is clamped on the surface of the structure module; the second PCB is clamped into a clamping groove; and a wire is connected with an interface of the second PCB. When the structure module of the assembled rotational conductive module and the hinge assembly rotate relatively, the conductive needles can be always propped against the corresponding conductive channels, thereby achieving conductive transmission at an arbitrary angle. The conductive needles and the corresponding conductive channels are connected in a sliding manner, thereby overcoming the problems that an internal wire of a rotating shaft is wound and is easily broken in the prior art. The hinge assembly can rotate back and forth in a hinge plane, and furthermore, the structure module can freely rotate around the guide post, so that the assembled rotational conductive module is great in degree of freedom, and stable conduction can be achieved while multi-angle structure connection is achieved.

The invention discloses a chord grinding machine. The chord grinding machine comprises a machine frame, a guide rail, two grinding wheels, a drive mechanism and a chuck, wherein the two grinding wheels are driven by a first motor, the drive mechanism is used for driving the two grinding wheels to horizontally move, the chuck is arranged on the machine frame through a rotary shaft and is driven by a servo motor to rotate, an annular groove is formed in the outer circumferential surface of the chuck, one or more working grooves penetrating through the two bottom faces of the chuck are formed in the edge of the chuck in the axial direction, the depth of the working grooves is smaller than that of the annular groove, the chuck is arranged between the two grinding wheels and is parallel with the two grinding wheels, the position where each grinding wheel is located on the machine frame is higher than the position where the chuck is located on the machine frame, the height of the bottommost end of each grinding wheel is smaller than that of the topmost end of the chuck, the guide rail is composed of a front guide rail section and a rear guide rail section, and the chuck is located between the front guide rail section and the rear guide rail section. The chord grinding machine has the advantages that in the process that the grinding wheels grind tile-shaped magnets, the positions of the tile-shaped magnets are fixed relatively, and the tile-shaped magnets will not twist in the grinding process, so that form and location tolerance is avoided.

A twisting-preventive compound pendulum contacting by circular spherical grooved surface and relates to college physical test, in particular to manufacturing of a twisting-preventive pendulum. A pendulum rod in a physics lab is generally in linear contact with a hanging rod and always twists. A kind of a pendulum rod is in spot contact via a knife edge but is poor in durability. The technical scheme of the twisting-preventive compound pendulum includes that a circular hole is reserved on the pendulum rod, a circular groove is reserved at the center of the circular hole, the bottom of the cross section of the circular groove is semi-circular, a projection in the shape of a thin circular cake is formed on the hanging rod, the top of the cross section of the cake is semi-circularly formed, the diameter of the semicircular top of the hanging rod is smaller than that of the semicircular bottom of the groove of the hanging rod, so that two spherical surfaces are guaranteed to be in spot contact. The hanging rod in spherical contact is small in friction, low in abrasion and high in durability. Vertical state of the swing rod can be guaranteed and no twisting is caused due to the fact that the spherical contact is spot contact, test error is reduced, testing accuracy is increased, horizontal adjustment procedures of instruments are reduced and test speed is increased.

The invention provides a slasher creel. According to the technical scheme, the slasher creel comprises a base and a plurality of pairs of rack bodies which are mounted on the base and are used for supporting warp beams. The pairs of rack bodies are arranged in the same plane in parallel, and the heights of the pairs of rack bodies are the same. According to the slasher creel, the rack bodies which are used for supporting the warp beams are arranged in the same plane in parallel, the heights of the rack bodies are the same, the distances between the warp beams can be effectively shortened compared with a traditional beam creel of an up-down layer structure in the first map, and warps can be effectively prevented from being twisted together. Through verification of experiments, under the condition that the wraps are wet (is not dried after dewatering), the condition of warp twisting does not happen, the drying step which has to be executed after warp dyeing is omitted, and production efficiency is improved. The slasher creel has the advantages that the distances of the warp beams can be effectively shortened, the warps can not be twisted together without being dried, the drying step is omitted, and the production efficiency is improved.
