[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figure 1-4 As shown, the present invention is a method for processing a motor cover, which can process two motor covers at the same time, thereby improving the processing efficiency of the motor cover 100.

[0025] Specifically, it includes a box body 1 and a chuck member 2 provided on the upper and lower sides of the box body 1. A cavity 11 is provided inside the box body 1. The cavity 11 is generally disc-shaped to prevent the tool (not shown) from scraping the inner wall of the cavity 11 during subsequent processing. A tool entrance 12 connected to the cavity 11 is provided on the front of the box body 1. The tool entrance 12 is in the shape of a circular hole. An observation hole 13 connected to the cavity 11 is provided on both the left and right sides of the box body 1. The two observation holes 13 are symmetrically arranged on the left and right and are both located in the middle of the corresponding side surfaces. The two observation holes 13 are circular holes, which makes it convenient for the staff to confirm whether the tool has moved to the preset position in the cavity 11 through the observation holes 13. A cutting hole 14 connected to the cavity 11 is provided on both the upper and lower sides of the box body 1. The two cutting holes 14 are symmetrically arranged on the upper and lower sides and are located in the middle of the corresponding side surfaces. The shape of the cutting hole 14 is the same as the shape of the concave arc groove 101 of the motor cover 100 to be processed. Each cutting hole 14 is surrounded by a locating pin 15 that engages with the motor cover 100. When securing the motor cover 100, the motor cover 100 can be first placed over the locating pins 15 to position the motor cover 100 so that the cutting hole 14 aligns with the concave arc groove 101 defined on the motor cover 100. In this embodiment, the locating pins 15 are cylindrical, with two locating pins 15 spaced apart.

[0026] A flange 3 is provided on the back of the box body 1. Preferably, the flange 3 and the box body 1 are integrally formed. The box body 1 can be quickly installed on the rotating table through the flange 3, so that the rotating table drives the box body 1 to rotate.

[0027] The chuck components 2 are arranged on the upper and lower side surfaces of the box body 1 and are located around the cutting hole 14. Specifically, four pairs of chuck components 2 are arranged around each cutting hole 14. Each pair of chuck components 2 includes a fixed threaded rod 21, a pressure block 22 and a nut 23. One end of the fixed threaded rod 21 is fixed to the box body 1, and the other end is provided with a thread that matches the nut 23. The pressure block 22 is provided with a guide hole for observing the upper and lower ends and matching the fixed threaded rod 21. The pressure block 22 is sleeved on the fixed threaded rod 21 through the guide hole and has an interference fit with it. The nut 23 is provided above the pressure block 22 and is threadedly matched with the fixed threaded rod 21.

[0028] Furthermore, the pressing block 22 is provided with threaded holes running through the upper and lower ends, and a support bolt 24 is adapted to be installed in the threaded hole. The bolt head 241 of the support bolt 24 abuts against the box body 1. When the pressing block 22 clamps and fixes the motor cover 100, one end of the pressing block 22 is pressed against the motor cover 100. At this time, the support bolt 24 can support the other end of the pressing block 22, thereby ensuring the stability of the pressing block 22 when fixing the motor cover 100 and preventing the pressing block 22 from tilting to one end.

[0029] The specific steps of processing the motor cover 100 are as follows:

[0030] S1. Fix the two motor covers 100 on the upper and lower sides of the box body 1 respectively through the clamping members 2 and arrange them symmetrically so that the areas to be processed of the motor covers 100 correspond to the cutting holes 14.

[0031] Specifically, the sides of the two motor covers 100 that require machining are aligned with the upper and lower sides of the housing 1, respectively, so that the locating pins 15 are inserted into the locating holes on the motor covers 100. At this point, the cutting holes 14 correspond to the positions of the pre-machined concave arc grooves 101 on the motor covers 100. The support bolts 24 in the chuck member 2 are rotated to adjust the height of the pressure block 22 so that one end of the pressure block 22 presses against the motor cover 100. The nut 23 is then rotated to press the pressure block 22 tightly against the motor cover 100, securing the motor cover 100 to the side of the housing 1. Four pairs of chuck members 2 are respectively attached to the four corners of the motor cover 100, firmly securing the two motor covers 100 to the upper and lower sides of the housing 1.

[0032] S2. Insert the tool into the cavity 11 from the tool entrance and engage with the motor cover 101.

[0033] Specifically, the tool can extend from the front of the box through the tool entrance 12 into the cavity 11 via its own telescopic shaft, so that the tool fits into the motor cover 100;

[0034] S3. The housing 11 is driven to rotate around its axis by a rotating table (not shown), driving the two motor covers 100 to rotate around their axis, so that the tools are exposed from the two cutting holes 14 in turn and concave arc grooves 101 are machined on the two motor covers 100 in turn.

[0035] Specifically, the rotating table drives the box body 1 to rotate around the axis, driving the two motor covers 100 to rotate around the axis, and the tool adjusts the depth of the tool inserted into the cavity 11 and the distance between the tool and the motor cover 100 according to the shape of the concave arc groove 101 to be processed, so that every time the box body 1 rotates one circle, the tool passes through the two cutting holes 14 in turn and emerges from the cutting holes 14 to cut the corresponding motor covers 100, so that the tool can process two motor covers 100 when the box body rotates one circle. Compared with the previous fixture that can only clamp one motor cover 100, the processing efficiency of the motor cover 100 in this application is twice that of the previous one, which greatly improves the processing efficiency of the motor cover 100.

[0036] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
