Description

Technical Field

[0001] This utility model relates to the technical field of computer back cover processing equipment, and in particular to a clamping component for grinding computer back covers. Background Technology

[0002] Since computers can be categorized into low-end, mid-range, and high-end models, the materials used for their back covers vary significantly depending on the model. Computer back covers can be broadly classified into metallic and non-metallic materials, and the processing techniques used also differ depending on the material. Most non-metallic computer back covers are manufactured using injection molding.

[0003] In the injection molding process for producing computer back covers, molten raw material is injected into a mold, and the material is allowed to cool and solidify. Due to gaps between the molded parts, burrs appear at the edges of the finished computer back cover. Before sanding to remove these burrs, the computer back cover needs to be secured to improve sanding accuracy and reduce the impact of sanding on dimensional errors. However, existing clamping assemblies for sanding computer back covers require multiple clamping operations throughout the sanding process to remove burrs from all edges, significantly impacting overall sanding efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a clamping component for polishing computer back covers, so as to solve the problem that multiple clamping and fixing are required during the polishing process, which has a significant impact on the efficiency of the entire polishing and deburring process.

[0005] To achieve the above objectives, this utility model provides a clamping assembly for polishing computer back covers, including a polishing chamber and a tapered protrusion fixed within the polishing chamber. The clamping assembly for polishing computer back covers further includes:

[0006] Rotate the base seat located on top of the conical protrusion.

[0007] A support frame fixed to the top of the grinding chamber.

[0008] Telescopic cylinder fixed to the support frame.

[0009] Rotate the connecting shaft located on the output end of the telescopic cylinder.

[0010] A top pressure seat fixed to the bottom of the connecting shaft.

[0011] An adjustment part is provided between the support frame and the connecting shaft, which is used to drive the top pressure seat and the bottom support seat to rotate synchronously in the circumferential direction when they are pressed together.

[0012] Preferably, the adjustment unit includes:

[0013] A horizontal support block fixed to the output end of the telescopic cylinder.

[0014] Rotate the splined shaft mounted on the horizontal support block, and the top end of the splined shaft is rotatably inserted into the support frame.

[0015] A drive motor mounted on the support frame.

[0016] A bevel gear is fixed to the output end of the drive motor, and a bevel gear is also movably sleeved on the top end of the spline shaft, with the tooth surfaces of the two bevel gears meshing.

[0017] Two flat gears are respectively fixedly sleeved on the bottom end of the splined shaft and the connecting shaft, and the tooth surfaces of the two flat gears mesh with each other.

[0018] Preferably, the cross support block is located near the connecting shaft, and the flat gear is located between the top pressure seat and the cross support block.

[0019] Preferably, the clamping assembly for polishing the computer back cover further includes an anti-slip sleeve fixedly sleeved on the outside of the base, the base corresponding to the top pressure seat.

[0020] Preferably, the outer surface of the conical protrusion is an inclined curved surface, and the top dimension of the conical protrusion is smaller than the bottom dimension of the base.

[0021] Preferably, the clamping assembly for polishing the computer back cover further includes a sliding seat slidably sleeved on the support frame, and the support frame is provided with a driving member for driving the sliding seat to move linearly.

[0022] Preferably, the clamping assembly for polishing the computer back cover further includes a polishing machine slidably disposed within the sliding seat, and the sliding seat is provided with a polishing drive unit for driving the polishing machine to slide linearly.

[0023] The beneficial effects of this utility model are as follows: By using the telescopic cylinder, top pressure seat, bottom support seat, and adjustment part in cooperation, the computer back cover only needs to be clamped and fixed once during the polishing process. When polishing different boundaries on the computer back cover, the orientation of the boundary to be polished on the computer back cover can be adjusted circumferentially by the adjustment part, so that the boundaries on all directions of the computer back cover can face the polishing machine in sequence, thereby smoothly completing the burr polishing operation on all boundaries of the computer back cover, improving the efficiency of burr polishing at the boundaries of the computer back cover, and improving the comprehensiveness of burr polishing. Moreover, the entire burr polishing operation is completed in a semi-enclosed environment in the polishing chamber, effectively avoiding excessive dust overflow into the working environment, greatly reducing the impact of dust on the operator's respiratory health, and improving the health and safety of the operator during long-term operation.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0032] like Figures 1 to 3 As shown, a clamping assembly for polishing a computer back cover includes a polishing chamber 1 and a tapered protrusion 12 fixed inside the polishing chamber 1. The clamping assembly for polishing a computer back cover also includes:

[0033] Rotate the bottom support 2 located on top of the conical protrusion 12.

[0034] Support frame 3 fixed to the top of the grinding chamber 1.

[0035] Telescopic cylinder 4 is fixed on support frame 3.

[0036] Rotate the connecting shaft 5 located on the output end of the telescopic cylinder 4.

[0037] Top pressure seat 10 is fixed to the bottom of the connecting shaft 5.

[0038] An adjustment part 6 is provided between the support frame 3 and the connecting shaft 5. The adjustment part 6 is used to drive the top pressure seat 10 and the bottom support seat 2 to rotate synchronously in the circumferential direction when they are pressed together.

[0039] This design allows for easy and efficient operation. After the computer back cover is initially placed on the base 2, the telescopic cylinder 4 can be extended to push down the top pressure seat 10 until the computer back cover is pressed and clamped between the base 2 and the top pressure seat 10. After grinding a certain edge of the computer back cover, while keeping the computer back cover clamped, the top pressure seat 10 can be rotated circumferentially by the control adjustment unit 6 to make the edge to be ground on the computer back cover face the grinding direction. This process is repeated until the burr grinding operation on all edges of the computer back cover is completed. The operation is simple and efficient. Furthermore, during the entire grinding and deburring process of a computer back cover, there is no need to perform multiple clamping and fixing operations while adjusting the orientation of the computer back cover edges, thus improving the efficiency of the entire grinding and deburring operation of the computer back cover.

[0040] like Figure 2 and Figure 3 As shown, the adjustment unit 6 includes:

[0041] A horizontal support block 63 is fixed to the output end of the telescopic cylinder 4.

[0042] Rotate the splined shaft 61 located on the horizontal support block 63, and the top end of the splined shaft 61 will be rotatably inserted into the support frame 3.

[0043] A drive motor 64 is mounted on the support frame 3.

[0044] A bevel gear 62 is fixed on the output end of the drive motor 64, and a bevel gear 62 is also movably sleeved on the top end of the spline shaft 61, with the tooth surfaces of the two bevel gears 62 meshing.

[0045] Two spur gears 65 are respectively fixedly sleeved on the bottom end of the spline shaft 61 and the connecting shaft 5, and the tooth surfaces of the two spur gears 65 mesh with each other.

[0046] The horizontal support block 63 is close to the connecting shaft 5, and the flat gear 65 is located between the top pressure seat 10 and the horizontal support block 63.

[0047] When it is necessary to adjust the orientation of the edge to be polished on the computer back cover, start the drive motor 64, and through the power transmission of two bevel gears 62, spline shaft 61 and two flat gears, realize the circumferential angle deflection adjustment of the drive top pressure seat 10, so that the edge to be polished on the computer back cover adjacent to the edge to be polished is deflected to the polishing direction, and the computer back cover is kept in a clamped and fixed state throughout the process, which is simple and efficient.

[0048] like Figure 3 As shown, the clamping assembly for sanding the computer back cover also includes an anti-slip sleeve 11 fixedly sleeved on the outside of the base 2. The base 2 corresponds to the top pressure seat 10. This design can improve the friction between the base 2 and the computer back cover, improve the circumferential stress resistance of the computer back cover after clamping and fixing, and improve the support stability of the computer back cover and the structural strength of the boundary after the computer back cover is clamped and fixed by the relative arrangement of the base 2 and the top pressure seat 10, so as to avoid the problem of up and down shaking at the boundary during sanding, which would affect the sanding effect.

[0049] like Figures 1 to 3 As shown, the outer surface of the conical protrusion 12 is an inclined curved surface, and the top dimension of the conical protrusion 12 is smaller than the bottom dimension of the base 2. This design allows the dust or debris generated during grinding to slide down the inclined curved surface of the conical protrusion 12 to the boundary of the grinding chamber 1, so that the dust and debris can be collected and disposed of later. It also prevents the dust and debris generated during grinding from falling between the top of the conical protrusion 12 and the bottom of the base 2, thus avoiding the accumulation of dust or debris between the two and increasing the resistance when the base 2 rotates circumferentially.

[0050] like Figure 1 , Figure 2 As shown, the clamping assembly for grinding the computer back cover also includes a sliding seat 7 slidably sleeved on the support frame 3. The support frame 3 is provided with a driving component 8 for driving the sliding seat 7 to move linearly. The driving component 8 includes a first lead screw rotatably disposed on the top of the support frame 3 and a servo motor for driving the first lead screw to rotate. The first lead screw is threadedly connected to the sliding seat 7.

[0051] The clamping assembly for polishing the computer back cover also includes a polishing machine 13 slidably disposed within a sliding seat 7. The sliding seat 7 is provided with a polishing drive unit 9 for driving the polishing machine 13 to slide linearly. The polishing drive unit 9 includes two supporting vertical plates that are relatively fixed on the sliding seat 7. A limiting horizontal plate is relatively fixed between the two supporting vertical plates. A second lead screw is rotatably disposed between the two supporting vertical plates. A nut seat is threaded onto the second lead screw. The nut seat is fixed to the top of the polishing machine 13 and is slidably disposed between the two limiting horizontal plates.

[0052] This design allows the position of the grinder 13 to be adjusted radially from the grinding chamber 1 and perpendicular to the grinding chamber 1, so as to complete the burr removal operation at the edge of the computer back cover in the horizontal direction and improve the grinding accuracy.

[0053] Working principle: After the computer back cover is placed on the base 2, the telescopic cylinder 4 is extended and the top pressure seat 10 is pushed down until the computer back cover is pressed and clamped between the base 2 and the top pressure seat 10, thus completing the clamping and fixing operation of the computer back cover. Then, the drive unit 8 drives the sliding seat 7 to move the polishing machine 13 and the polishing drive unit 9 close to the edge of the computer back cover to be polished until the polishing surface of the output end of the polishing machine 13 is aligned with the edge of the computer back cover to be polished. Then, the polishing drive unit 9 and the polishing machine 13 are started so that the polishing machine 13 polishes and removes the burrs on the edge of the computer back cover, and polishes one side of the computer back cover. After the edge grinding is completed, the control drive 8 drives the sliding seat 7 away from the base seat 2, and drives the grinding drive 9 and the grinding machine 13 to move synchronously until the distance between the grinding machine 13 and the computer back cover is greater than half the diagonal length of the computer back cover. While keeping the computer back cover clamped and fixed, the drive motor 64 is started and the power is transmitted through two bevel gears 62, spline shaft 61 and two flat gears to realize the circumferential angle adjustment of the drive top pressure seat 10, so that the edge to be ground on the computer back cover faces the grinding machine 13, and the grinding operation continues. This process is repeated to complete the burr removal operation at all the edges of the computer back cover.
