Description

Technical Field

[0001] This utility model relates to the field of gear shifting mechanism technology, and in particular to a convenient disassembly and assembly combination pressing device suitable for gear shifting mechanisms. Background Technology

[0002] The gear shifting mechanism is a key component in the automotive transmission system, used to switch between different gears in the gearbox. In the production and assembly process of the automotive gear shifting mechanism, it is often necessary to press-fit multiple parts such as bushings, bearings, and gears together.

[0003] A search revealed a press-fitting machine with publication number CN210754743U, comprising a base, an industrial control computer, a stamping assembly, a clamping assembly, a lifting assembly, and a support assembly. The industrial control computer is fixed to the side wall of the base. The stamping assembly includes a hydraulic cylinder, a push plate, and a press head. The hydraulic cylinder is mounted on the upper part of the base, the push plate is connected to the movable end of the hydraulic cylinder, and the press head is fixedly mounted on the lower surface of the push plate. A rotating threaded rod pushes an arc-shaped clamping block to move, clamping and fixing shaft-like parts to facilitate stamping. A motor drives a lead screw to rotate, causing the lead screw to move a moving seat up and down, which in turn moves the hydraulic cylinder up and down to adjust the height, facilitating the processing of the stamped parts. Then, the execution component is activated, and the hydraulic cylinder moves the push plate down, causing the press head on the lower surface of the push plate to stamp the part to be stamped.

[0004] The device in the disclosed patent cannot quickly change the pressure head according to the work requirements during the pressing operation. It requires time-consuming and laborious disassembly and reassembly of the pressure head, which affects the work efficiency. Furthermore, the disassembly and reassembly are troublesome when inspecting and maintaining the pressure head, resulting in low practicality. Utility Model Content

[0005] In response to the technical problems in existing patents, such as the inability to quickly change the pressure head according to work requirements during pressing operations, the need for time-consuming and laborious disassembly and reassembly of the pressure head, which affects work efficiency, and the cumbersome disassembly and reassembly during pressure head maintenance, resulting in low practicality, this utility model provides a convenient disassembly and reassembly combined pressing device suitable for shifting mechanisms.

[0006] The technical solution adopted in this utility model is: a convenient disassembly and assembly combined pressing device suitable for gear shifting mechanisms, comprising:

[0007] The press-fitting structure includes a worktable, a mounting bracket fixedly welded to the top of the worktable, a hydraulic cylinder bolted to the top of the mounting bracket, a frustum fixedly mounted on the output shaft of the hydraulic cylinder, and a press head mounted on the bottom of the frustum.

[0008] An adjustment structure is mounted on the circular platform and is used to adjust the type of the pressure head according to working requirements.

[0009] A disassembly / assembly assembly is installed at the bottom of the adjustment structure and is used to disassemble / assemble the pressure head.

[0010] The assembly / disassembly assembly includes a positioning seat installed at the bottom of the adjustment structure, a positioning plate installed at the top of the pressure head, a positioning block fixedly welded to the top of the positioning plate, and an assembly / disassembly structure installed inside the positioning seat.

[0011] Furthermore, the bottom of the positioning seat is provided with a positioning groove, and a reset groove is provided on one side of the positioning groove. The disassembly and assembly structure includes a reset plate fused to the inner wall of the reset groove by a reset spring, a reset post and a limiting post fixedly welded to one side of the reset plate, and a disassembly and assembly post fixedly welded to one end of the reset post. The other end of the reset spring is fixedly connected to the inner wall of the reset groove of the positioning seat.

[0012] Furthermore, the positioning block cooperates with the positioning groove, and a limiting hole is formed on the positioning block, which cooperates with the limiting post.

[0013] Furthermore, the truncated cone has a through hole, and the adjustment structure includes a column rotatably installed inside the through hole, a first gear fixedly welded to the top of the column, a turntable fixedly welded to the bottom of the column, and an adjustment component installed on the top of the truncated cone.

[0014] Furthermore, the adjusting component includes an adjusting motor bolted to the top of the L-frame on the top of the truncated cone and a second gear fixedly mounted on the output shaft of the adjusting motor, wherein the first gear meshes with the second gear.

[0015] Furthermore, the positioning seat is fixedly welded to the bottom of the turntable.

[0016] The beneficial effects of this utility model are:

[0017] The motor drives the second gear to rotate, which meshes with the first gear. The first gear drives the turntable to rotate via the column. The appropriate pressure head model is selected based on usage requirements, allowing the required pressure head to rotate to the top of the workpiece. This is simple and convenient. Combining different pressure head models eliminates the need for time-consuming and laborious disassembly and assembly, improving work efficiency. The disassembly column moves the reset column, which in turn moves the reset plate to compress the reset spring. The reset plate then moves the limit column, controlling the relative position of the limit column and the limit hole. This, in turn, controls the relative position of the positioning block and the positioning groove, facilitating the disassembly and assembly of the positioning seat and the positioning plate, as well as the disassembly and assembly of the pressure head, and simplifying maintenance and replacement.

[0033] The adjustment structure 2 is mounted on the frustum 104. The adjustment structure 2 is used to adjust the model of the pressure head 105 according to the working requirements.

[0034] The frustum 104 has a through hole. The adjustment structure 2 includes a column 201 rotatably installed inside the through hole, a first gear 202 fixedly welded to the top of the column 201, a turntable 203 fixedly welded to the bottom of the column 201, and an adjustment component 204 installed on the top of the frustum 104.
