Description

Technical Field

[0001] This application relates to the technical field of motor riveting, and in particular to a micro motor end cap anti-detachment riveting device. Background Technology

[0002] As a core component of precision drive devices, micro motors are widely used in medical devices, micro robots, precision instruments and meters and other fields. Their housing components not only need to provide stable electromagnetic shielding and mechanical support, but also need to ensure the axial positioning reliability of internal precision components such as rotors and stators. In recent years, some manufacturers have adopted plastic deformation processes to fix the end of the housing, such as stamping to make the housing port radially shrink.

[0003] The stamping machine has a mounting block on which a stamping block is fixed with mounting screws. The stamping block holds the motor to be riveted, and the stamping machine performs the riveting process on the motor placed on the stamping block. However, when processing motors of different diameters, stamping blocks of different diameters must be replaced to accommodate the different sizes of motors. When replacing a stamping block, the mounting screws between the stamping block and the mounting block must be removed, the original stamping block removed from the mounting block, and then a new stamping block reinstalled on the mounting block using mounting screws. This method requires removing and installing the mounting screws every time a stamping block is replaced, which wastes time and affects work efficiency. Utility Model Content

[0004] To address the issue of wasted time and reduced work efficiency when replacing stamping blocks, this application provides a micro motor end cap anti-detachment riveting device.

[0005] The micro-motor end cap anti-detachment riveting device provided in this application adopts the following technical solution:

[0006] A micro-motor end cap anti-detachment riveting device includes an electric stamping machine, a clamping mechanism, and a lower stamping block. The electric stamping machine is equipped with a base, the clamping mechanism is mounted on the base, and the lower stamping block is mounted on the clamping mechanism. The lower stamping block is used to hold the motor to be riveted. The clamping mechanism includes a support cylinder, a rotating block, and a clamping execution assembly.

The rotating block is used to drive the clamping execution assembly to clamp the lower stamping block.

[0007] By adopting the above technical solution and setting the clamping mechanism, the lower stamping block can be quickly disassembled and assembled, reducing the time for replacing the stamping block and improving work efficiency. When the rotating block moves upward along the support cylinder, the clamping execution component clamps the lower stamping block.

[0015] By adopting the above technical solution, when the clamping ring moves upward, the sliding support frame set at the upper end of the clamping ring drives the clamping block 4401 to slide on the support cylinder 45 through the inclined sliding support groove 4404, thereby clamping the lower punch block.

[0016] Preferably, the clamping mechanism further includes an mounting component and a mounting plate. The lower end of the support cylinder is connected to the upper top wall of the mounting plate. The mounting component is used to fix the mounting plate to the machine base. The lower end of the mounting component is provided with a mounting slider.

[0019] By adopting the above technical solution, the crankshaft rotates once with the drive disc, and the crankshaft drives the push block and the upper punch block installed on the push block to press downward once, thereby completing the riveting of a motor placed on the machine base.

[0020] Preferably, the electric stamping machine further includes a suspension plate, a support plate is connected to the upper end of the support column, the lower end of the suspension plate abuts against the support plate, a suspension rod is connected to the lower end of the suspension plate, and the lower end of the suspension rod passes through the support plate and connects to the upper end of the connecting block.

[0021] By adopting the above technical solution, the connecting block is slidably connected to the support column, thus limiting the connecting block to only one degree of freedom to move along the axis of the support column.

The three abutting blocks 4301 are arranged in the circumferential direction along the axis of the rotating block 43. The upper ends of the three abutting blocks abut against the clamping execution component 44.

[0039] Reference Figures 5-7 The clamping execution component 44 includes a clamping block 4401, a sliding support frame 4403, and a clamping ring 4406. In this embodiment, three support sliders 4501 are fixedly connected to the outer wall of the support cylinder 45. The three support sliders 4501 are arranged circumferentially along the axis of the support cylinder 45. The support cylinder 45 also has three clamping sliding holes 4502, the axes of which are perpendicular to the axis of the support cylinder 45. The three clamping sliding holes 4502 are arranged circumferentially along the axis of the support cylinder 45. The inner ring of the clamping ring 4406 has three support sliding grooves 4405, which are arranged circumferentially along the axis of the clamping ring 4406. Each support sliding groove 4405 has... Corresponding to a support slider 4501, a clamping ring 4406 is slidably fitted onto the outer wall of the support cylinder 45 via a support groove 4405. The upper ends of three abutting blocks abut against the lower end of the clamping ring 4406. The upper end of the clamping ring 4406 is fixedly connected to three sets of sliding support frames 4403. The three sets of sliding support frames 4403 are arranged circumferentially along the axis of the clamping ring 4406. Each set of sliding support frames 4403 consists of two sliding support frames 4403 arranged side by side. Each sliding support frame 4403 is provided with a sliding support groove 4404 for the support block 33 to slide. In this embodiment, the sliding support groove 4404 is vertically arranged, and the lower end of the sliding support groove 4404 is inclined towards the axis of the support cylinder 45.

[0040] The sliding support frame 4403 drives the clamping block 4401 to slide on the support cylinder 45 through the inclined sliding support groove 4404; there are 3 clamping blocks 4401, one end of each clamping block 4401 is fixedly connected to a sliding support rod 4402, the 3 clamping blocks 4401 are slidably connected to the 3 sliding support frames 4403 through the sliding support rods 4402 respectively, and the other end of each clamping block 4401 is slidably connected to the support groove 4405 on the support cylinder 45.

[0041] The working process of the clamping mechanism 40 is as follows: When it is necessary to clamp the lower punch block 50, the lower punch block 50 is first placed in the support cylinder 45, and then the rotating block 43 is rotated in the forward direction. The rotating block 43 moves upward along the axis of the support cylinder 45 and moves upward against the clamping ring 4406. The clamping ring 4406 then drives the three clamping blocks 4401 to move closer to the center of the clamping ring 4406 through the three sets of sliding support frames 4403, thereby clamping the lower punch block 50 in the support cylinder 45. When it is necessary to remove the lower punch block 50, the rotating block 43 is rotated in the reverse direction. The rotating block 43 moves downward along the axis of the support cylinder 45. The clamping ring 4406 moves downward under the action of gravity and drags the three clamping blocks 4401 away from the center of the clamping ring 4406.

[0042] The implementation principle of the micro motor end cap anti-detachment riveting device in this application embodiment is as follows: The lower punch block 50 is placed on the clamping mechanism, and then the lower punch block 50 is clamped by rotating the rotating block 43 on the clamping mechanism. The motor 60 is then placed on the lower punch block 50, and the drive motor is started. The drive motor drives the drive disc 3601 via a belt, and the drive disc 3601 drives the push block 35 and the upper punch block 3503 downwards to rivet the motor 60 via the crankshaft 36. When the lower punch block 50 needs to be replaced, the rotating block 43 is rotated in the opposite direction to remove the lower punch block 50 that was originally clamped on the clamping mechanism. A new lower punch block 50 is then placed on the clamping mechanism, and the rotating block 43 is rotated again to clamp the new lower punch block 50 on the clamping mechanism.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
