Description
Description SNAP SPRING ASSEMBLING DEVICE FOR DISC SPRING Technical field The invention relates to a snap spring assembling device for disc spring, belonging to the technical field of leaf spring mounting devices. Background art After a disc spring is mounted on various shafts, a snap spring needs to be disposed at the position of the shaft adjacent to the end surface of the disc spring to limit the axial displacement of the disc spring. The disc spring usually occupies the position of a snap spring slot for mounting the snap spring because of the axial deformation of the disc spring, so when the snap spring is mounted, the disc spring needs to be axially compressed to free the position of the snap spring slot for mounting the snap spring such that the snap spring can be mounted. The disc spring usually has strong axial spring force, so the snap spring can be assembled by applying an even axial force to the disc spring to completely free the annular snap spring slot on the shaft. There is no special snap spring assembling device for axially compressing a disc spring to free a snap spring slot for snap spring assembly in the prior art, which makes it is hard to assemble a snap spring for a disc spring and possibly damage the disc spring or the shaft. Summery of the invention The invention solves the problem in the prior art that a snap spring is difficult to be assembled on a shaft on which a disc spring is mounted and provides a snap spring assembling device for disc spring convenient for assembling a snap spring on shaft. The above technical object of the invention is realized by the following technical scheme: the snap spring assembling device for disc spring comprises a bedplate, a positioning seat is fixedly mounted on the bedplate, the positioning seat is provided with a positioning hole in which a lifter is disposed, the lifter is connected with a lifting drive mechanism, one side of the upper end of the positioning seat is articulated to one end of a press plate, the other side of the upper end of the positioning seat opposing to the articulated part of the upper end to the press plate is provided with a limiting structure, the press plate is provided with a through hole at the middle part, and when the other end of the press plate is fitted with the limiting structure, both ends of the press plate can not move up and down under the restrictions of the articulated part and the limiting structure, respectively. In assembly, rotor shaft assembled with a disc spring or other workpiece shaft is positioned in the positioning hole of the positioning seat and supported on the lifter, then the press plate rotates around the articulated point to fit the other end of the press plate with the limiting structure, the press plate stops rotating when the through hole at the middle part of the press plate is coaxial with the positioning hole of the positioning seat, and both ends of the press plate can not move up and down due to the restrictions of the articulated part and the limiting structure, respectively; the lifting drive mechanism drives the lifter to rise, the rotor shaft assembled with the disc spring or other workpiece shaft is accordingly brought about to rise, the disc spring can not rise due to the limitation by contacting with the lower surface of the press plate, the position of a snap spring slot on the rotor shaft or other workpiece shaft for mounting a snap spring adjacent to the disc spring is completely free, the snap spring can be conveniently assembled in the snap spring slot by a snap spring plier, then the liftino- drive mrchanikm drivo', the lifter to fqll the rotor ,hnft or other wunrknipcp shaft moves back downward to finish the assembly of the snap spring, and the assembly is convenient for operation and can not damage the disc spring or the shaft. Preferably, the lifting drive mechanism is a cylinder arranged under the lifter, and the piston rod of the cylinder is connected with the lifter. The cylinder is taken as the lifting drive mechanism by directly and fixedly connecting the piston rod of the cylinder to the lifter without other intermediate transmission members. Preferably, the lifting drive mechanism is of a gear-rack structure, the rack of the gear-rack structure is fixed to the lifter and is parallel to the axes of the positioning hole in the length direction, the gear of the gear-rack structure is meshed with the rack, and the gear is driven by a drive motor.

The stepless lifting of the lifter can be realized by using the screw rod to lift the lifter, so the lifting height of the lifter can be accurately controlled easily. Preferably, the press plate is arranged horizontally. Preferably, the other side of the upper end of the positioning seat opposing to the articulated part of the upper end to the press plate forms a first bulge which is higher than the articulated part of the upper end of the positioning hole to the press plate, the limiting structure is a cambered horizontal groove on the inner wall of the first bulge, and the cambered horizontal groove is fitted with the free end of the press plate. The first bulge formed on the upper end of the positioning seat and the cambered horizontal groove formed on the inner wall of the first bulge can facilitate the fit between the press plate and the cambered horizontal groove, which is inconvenient for operation. The limiting structure can be of the following structure: the upper end of the positioning seat is provided with a threaded hole, the press plate is provided with a through hole corresponding to the threaded hole, a lock screw penetrates through the through hole to fitted with the threaded hole of the upper end of the positioning seat and thus lock the press plate. Preferably, the articulated part of the upper end of the positioning seat to the press plate forms a second bulge, the end part of the press plate is articulated with the upper end of the second bulge, and the upper end of the positioning seat is provided with a first notch and a second notch which are positioned between the first bulge and the second bulge in the circumferential direction.
