[0025] To address the problems of existing polishing equipment being unable to reach deep grooves during grinding of workpieces with deep grooves due to their structure, requiring manual grinding, which results in high labor intensity, low processing efficiency, low product yield, and high production costs, this invention provides a deep groove workpiece polishing device. Figures 1 to 4 As shown, the deep groove workpiece polishing equipment includes: a lower support 8, which is used to fix deep groove workpieces 6. Multiple deep groove workpieces 6 can be fixed on the upper surface of the lower support 8, and are configured such that the groove extends along a first direction, which is... Figure 3 The vertical direction; polishing brush 1, which includes a strip-shaped brush head 11, such as... Figure 6 As shown, the brush head 11 is strip-shaped and extends along a first direction, in the same direction as the groove of the deep groove workpiece 6. An upper support 7, positioned above the lower support 8, supports and fixes the polishing brush 1. The brush head 11 extends downwards below the upper support 7, positioning it relative to the deep groove workpiece 6. The brush head 11 can penetrate into the groove of the deep groove workpiece 6, abutting against the bottom and sidewalls of the groove. A polishing brush motion assembly 2 drives the upper support 7 to reciprocate along the first direction, causing the brush head 11 to reciprocate along the length of the groove. The brush head 11 rubs against the bottom and sidewalls of the groove, thoroughly polishing them. Furthermore, multiple brush heads 11 are arranged at intervals along a second direction perpendicular to the first direction, enabling simultaneous polishing of multiple deep groove workpieces 6.

[0026] In a preferred embodiment, the brush head 11 is made of a flexible material and its width is slightly larger than the width of the groove. The brush head 11 is tightly fitted into the groove, effectively polishing the groove. Figure 10 This invention illustrates one structure of a deep-groove workpiece 6 to which this invention can be applied. The two ends of the groove are preferably open, allowing multiple deep-groove workpieces 6 to be polished simultaneously along the length of the same brush head 11. Furthermore, the number and spacing of the brush heads 11 can be adjusted according to the number and arrangement of the grooves. The material of the brush heads 11 can be selected according to the material of the deep-groove workpiece 6, such as fiber bristles or silicon carbide. The shape of the groove of the deep-groove workpiece 6 is not limited to a straight line; it can also be curved. By setting the material of the brush heads 11 to a flexible material, effective polishing can also be achieved using the polishing equipment described in this application.

[0027] Through the above technical solution, the deep groove workpiece and the polishing brush are respectively arranged opposite to each other on the lower support and the upper support. The brush head of the polishing brush is set as a strip, which is consistent with the groove direction of the deep groove workpiece and can abut against the bottom and side wall of the groove. Driven by the polishing brush motion assembly, the brush head abuts against the bottom and side wall of the groove and rubs repeatedly, which can fully polish the bottom and side wall of the groove, realize the automated polishing of the deep groove workpiece, reduce the labor intensity and production cost of workers, and improve the processing efficiency and product yield of products.

[0028] In some embodiments, such as Figure 2 , Figures 4 to 6 As shown, the polishing brush motion assembly 2 includes a first drive member 21 and a first guide member. The first guide member extends along a first direction, which is the same as the extension direction of the groove and the brush head 11. The first drive member 21 can drive the upper support member 7 to reciprocate along the length direction of the first guide member, so that the brush head 11 repeatedly rubs along the extension direction of the groove. The first drive member 21 is an electric cylinder or pneumatic cylinder in the prior art, which provides linear driving force.

[0029] In some embodiments, such as Figure 6 As shown, the first guide member includes a first guide rail 22 and a first slider 23. The first guide rail 22 extends along a first direction. One end of the first slider 23 is slidably connected to the first guide rail 22, and the other end is connected to the upper support member 7. The first driving member 21 can drive the first slider 23 and the upper support member 7 to reciprocate along the length direction of the first guide rail 22. As an alternative implementation, a linear bearing or roller can be used instead of the first slider 23.

[0030] In some embodiments, such as Figure 4 As shown, the upper support 7 is a horizontally placed frame. The polishing brush 1 also includes a brush head holder 12, with the brush head 11 mounted on it.

Specifically, after the polishing brush motion component 2 drives the brush head 11 to polish the groove of the deep groove workpiece 6, the fine-tuning component is used to adjust the position of the deep groove workpiece 6, and then the polishing brush motion component 2 drives the brush head 11 for polishing, ensuring that each part of the groove can be fully polished. In other alternative embodiments, the fine-tuning component 3 can also be used to adjust the position of the upper support member 7, causing the polishing brush 1 to undergo a slight compensating movement in the direction perpendicular to the groove.

[0032] In some embodiments, the fine-tuning component 3 includes a second drive member 31 and a second guide member, the second guide member extending along a second direction, and the second drive member 31 capable of driving the lower support member 8 to move along the length direction of the second guide member. The second drive member 31 is an electric cylinder in the prior art, or it can be a pneumatic cylinder, providing a linear driving force.

[0033] In some embodiments, the second guide member includes a second guide rail 32 and a second slider 33. The second guide rail 32 extends along a second direction. One end of the second slider 33 is slidably connected to the second guide rail 32, and the other end is fixedly connected to the lower support member 8. The second drive member 31 can drive the second slider 33 and the lower support member 8 to reciprocate along the length direction of the second guide rail 32. As an alternative implementation, a linear bearing or roller can be used instead of the second slider 33.

During the polishing process, the polishing liquid dripping from the water tank body 41 is discharged through the drain port 42 and the drain pipe 43. A fine-tuning assembly 3 is located below the tank body 41 and can drive the tank body 41 and the lower support member 8 to move in a second direction.

[0035] In some embodiments, the lower support member 8 includes a support plate 81 and a fixture 82. The support plate 81 is fixed in the groove 41, and the fixture 82 is disposed on the upper surface of the support plate 81 and can fix the deep groove workpiece 6.

[0036] In some embodiments, such as Figure 1 and Figure 2As shown, the deep groove workpiece polishing equipment also includes a cabinet 9, with an upper support 7, a lower support 8, and a polishing brush movement assembly 2 housed within the cabinet 9 to prevent polishing liquid from splashing during the polishing process. The cabinet 9 is equipped with a support frame for supporting and fixing the aforementioned components. Specifically, the first drive component 21, the first guide rail 22, the second drive component 31, and the second guide rail 32 are fixed to the support frame, while other components are correspondingly mounted on the first guide rail 22 and the second guide rail 32. An open drain pipe 43 is provided on the side of the cabinet for drainage. The cabinet 9 also includes a control cabinet to control the operation of the first drive component 21 and the second drive component 31.

[0037] In some embodiments, such as Figure 11 and Figure 12 As shown, the deep-groove workpiece polishing equipment also includes a polishing liquid tank assembly 5, which provides polishing liquid for the polishing process. The polishing liquid tank assembly 5 includes a tank body 51, a stirring pump 52, a stirring head 53, and a filter screen 54. The stirring pump 52 is located above the tank body 51, and the stirring head 53 is located inside the tank body 51.
