It can be manufactured and used, and achieves the positive effects of relatively accurate and reliable positioning, no offset of riveting points, no dislocation of riveting, and no loosening after riveting. The overall idea is as follows:

[0076] The second fixing plate 26 is a rectangular plate-like structure, made of stainless steel, sleeved on the vertical rod 23 and connected to the vertical rod 23, forming a reliable support structure and facilitating the connection of the microcomputer controller 11;

[0077] The guiding and supporting part 20 is provided, forming a reliable support structure and facilitating the connection and arrangement of other components;

[0078] Another implementation method:

[0079] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、Figure 5 , Figure 6 , Figure 8 As shown in Figure 5 , Figure 6 , and Figure 8 . During implementation, the first positioning member 30 includes: a base 31 connected to the bottom plate 21, and the base 31 has a first stepped through hole 31-1; a positioning piece 32 connected to the base 31 and inserted into the first stepped through hole 31-1.

[0080] The base 31 is a circular block structure made of stainless steel and is connected to the bottom plate 21 through internal hexagonal bolt parts. The base 31 forms a reliable support structure, which is beneficial to connecting the positioning piece 32 and limiting the riveting knives 33 to prevent the riveting knives 33 from yielding when contacting the riveting area 101, ensuring the riveting effect.

[0081] The outer shape of the positioning piece 32 is circular and is made of stainless steel. It is inserted and positioned with the first stepped through hole 31-1 through a small boss in the middle position and is connected to the base 31 through screws, ensuring the positioning accuracy and relatively good structural reliability.

The setting of the square slots 32-2 is beneficial to positioning the riveting cutter 33, ensuring the positioning accuracy of the riveting cutter 33, and facilitating the one-to-one alignment of the riveting cutter 33 and the riveting area 101;

[0084] The number of the riveting cutters 33 is four, which are arranged one-to-one with the square slots 32-2. One end of the riveting cutter 33 is inserted into the square slot 32-2, and the other end has an inward concave arc-shaped notch 33-1. The inward concave arc-shaped notch 33-1 protrudes from the square slot 32-2 and contacts the riveting area 101 to squeeze the riveting area 101. The riveting area 101 is concavely bent and deformed to form the riveting point. The material of the riveting cutter 33 is white steel. Inserted at the square slot 32-2 and contacting the riveting area 101 through the inward concave arc-shaped notch 33-1, when the assembly 100 of the motor and the gearbox is pressed down by the riveting main body 50, the riveting area 101 is gradually squeezed along the inward concave arc-shaped notch 33-1, and the riveting area 101 is concavely bent and deformed to form the riveting point, and the forming quality is relatively good, without riveting misalignment and without loosening after riveting;

[0090] The positioning block 41 is made of stainless steel. By inserting into the connecting block 42, the positioning block 41 can move along the connecting block 42, ensuring the concentricity between the positioning block 41 and the connector 53, which is beneficial to the insertion or disengagement of the positioning block 41 and the connector 53;

[0091] The connecting block 42 is made of hard aluminum, and its outer shape is generally a "T" shape. One end is connected to the slider 25-1 by screws, and the other end is inserted into the positioning block 41 and penetrates the positioning block 41, which is beneficial to linking the positioning block 41, and the positioning block 41 can move along the connecting block 42, ensuring the concentricity between the positioning block 41 and the connector 53;

The second positioning member 40 moves upwards along the guiding and supporting portion 20 to release the assembly 100 of the motor and the gearbox.

[0100] Regarding the structure of the assembly 100 of the motor and the gearbox:

[0101] See Figure 5 、 Figure 6 、 Figure 8 The assembly 100 of the motor and the gearbox includes: a motor 100-1 and a gearbox 100-2. There are four riveting areas 101 on the motor 100-1. The riveting areas 101 are extruded by the riveting cutter 33, causing concave bending deformation to form riveting points, so that the motor 100-1 and the gearbox 100-2 form the assembly 100 of the motor and the gearbox, forming a relatively integral whole.

[0102] The working principle is as follows: In the first state, one end of the assembly 100 of the motor and the gearbox is positioned on the first positioning member 30. The operator pulls down the second positioning member 40, and the second positioning member 40 disengages from the riveting main body 50. The second positioning member 40 moves towards the assembly 100 of the motor and the gearbox along the guiding and supporting portion 20. The second positioning member 40 positions the other end of the assembly 100 of the motor and the gearbox. The riveting main body 50 moves towards the second positioning member 40 to apply pressure at the second positioning member 40. The riveting area 101 on the assembly 100 of the motor and the gearbox is extruded by the first positioning member 30, causing concave bending deformation to form a riveting point.

[0103] In the second state, the riveting main body 50 rises and moves away from the assembly 100 of the motor and the gearbox, and drives the second positioning member 40 to move together (at this time, the wave screw 54 engages with the annular groove 41-31). The second positioning member 40 moves along the guiding and supporting portion 20 to release the other end of the assembly 100 of the motor and the gearbox.

[0104] The positioning is relatively accurate and reliable, there will be no offset of the riveting points, no misalignment in riveting, and after riveting, the motor 100-1 and the gearbox 100-2 will not become loose.

[0105] In the description, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicating orientation or positional relationship, are based on the positional relationship described in the drawings, and are only for the convenience of description or simplification of the description, rather than indicating a specific orientation that must be possessed; the operation process described in the embodiments is not an absolute usage step, and corresponding adjustments can be made during actual use;
