Description

Technical Field

[0001] This invention relates to the field of rearview mirror processing technology, specifically to a fixture system for grinding and polishing rearview mirrors. Background Technology

[0002] In the production of automotive rearview mirrors, the mirrors need to be polished after painting. Currently, this is mainly done manually. Since the amount of coating removed by polishing is generally small (usually 10-100μm), manual polishing is very easy to cause over-polishing. As a result, it is becoming increasingly difficult to meet quality requirements in terms of product consistency and pass rate.

[0003] The rearview mirror is a typical injection-molded thin-walled part with poor workpiece rigidity and lack of positioning reference, making installation and fixation difficult. Secondly, the rearview mirror is a semi-enclosed free-form curved surface, and grinding and polishing it requires a large axis rotation, which has strong interference. A professional fixture system needs to be designed to achieve robotic grinding and polishing. Summary of the Invention

[0004] The purpose of this invention is to provide a rearview mirror clamping system for grinding and polishing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixture system for grinding and polishing rearview mirrors, comprising: Support section for support; The clamping part is located on top of the support part. The clamping part includes a clamping base plate and a movable pressure plate that can be raised and lowered to adjust the upper part of the clamping base plate. One side of the movable pressure plate is provided with a contouring surface four that is higher than the horizontal plane of the clamping base plate. The outer side of the movable pressure plate is provided with a contouring surface three. The contouring surface three and the contouring surface four form a positioning groove for positioning the rearview mirror housing. The support part is located above the movable pressure plate and is used to support the interior of the rearview mirror housing.

[0006] Preferably, the support includes a mounting plate, the top of which is fixedly connected to a tooling column, and the fixture base plate is fixedly connected to the tooling column.

[0007] Preferably, the top of the fixture base plate is fixedly connected to a left mounting column and a right mounting column, both of which are slidably connected to the movable pressure plate.

[0008] Preferably, a locking screw is rotatably connected to the top of the fixture base plate, and the locking screw is threadedly connected to the movable pressure plate.

[0009] Preferably, the support includes a left positioning block and a right positioning block.

[0010] Preferably, the left mounting post is located on the side close to the contour processing surface four, and the left positioning block is fixed to the top of the left mounting post. The top of the left mounting post is the contour processing surface two with an arc-shaped structure.

[0011] Preferably, the right-side positioning block is fixed to the top of the right-side mounting post, and the outer side of the right-side positioning block is provided with a contoured machining surface for support from the rearview mirror.

[0012] Compared with the prior art, the beneficial effects of the present invention are: Adopting an innovative modular concept: by simply changing the corresponding contour block, different rearview mirror clamps can be quickly and flexibly switched, greatly improving work efficiency and flexibility; Minimal interference from the fixture: This ensures that the fixture's interference with the robot is minimized, allowing the robot to perform the grinding and polishing of the rearview mirrors smoothly and without obstruction. Rearview mirror installation and fixing: The installation process is simple and quick, and the fixing is firm and reliable, which greatly facilitates manual operation and improves work efficiency and convenience.

[0013] The use of contour block modules effectively avoids the risk of incorrect workpiece placement, strictly prevents collisions caused by incorrect workpiece placement, and provides strong protection for operational safety. Attached Figure Description

[0018] It should be noted that the fixture base plate 4 of this invention is fixedly installed on the tooling column 9 by screws, and the movable pressure plate 3 is fixed to the fixture base plate 4 by locking screws 8. The fixture base plate 4 and the movable pressure plate 3 form a workpiece lower clamping mechanism.

The top of the fixture base plate 4 is provided with a positioning groove that mates with the bottom of the workpiece 10, and the outer side of the contour machining surface 14 is provided with a protrusion and a limiting groove that mates with the workpiece 10. By rotating the locking screws 8, the movable pressure plate 3 is pushed downward, and the movable pressure plate 3 presses downward against the inner wall of the workpiece 10, thereby fixing the workpiece 10 to the outside of the left positioning block 1 and the right positioning block 6. The robot can easily perform rearview mirror grinding and polishing; the rearview mirror is easy and quick to install and fix, facilitating manual operation.

[0019] Please see Figure 1 , 2 As shown in Figure 3, the support includes a mounting plate 5, and a tooling column 9 is fixedly connected to the top of the mounting plate 5. The fixture base plate 4 is fixedly connected to the tooling column 9.

[0020] It should be noted that the mounting plate 5 of the present invention has mounting holes, which can be connected to external equipment, and the tooling column 9 can be connected by screws to form the base of the clamping system.

[0022] It should be noted that the left positioning block 1 and the left mounting post 2 of this invention are installed on the fixture base plate 4 with screws to position the left side of the workpiece 10. Furthermore, different rearview mirrors can be quickly switched by replacing the corresponding contour blocks. Similarly, the right positioning block 6 and the right mounting post 7 are installed on the fixture base plate 4 with screws to position the right side of the workpiece 10.

[0024] It should be noted that the upper edge of the fixture base plate 4 of this invention has a contour-machining surface 14, and the outer side of the mounting plate 5 has a contour-machining surface 13. Both are contour-machined according to the outer contour of the workpiece 10. After tightening the locking screw 8, the contour-machining surface 14 fits against the lower outer edge of the workpiece 10, and the contour-machining surface 13 fits against the lower inner edge of the workpiece 10, thereby clamping the lower part of the workpiece 10. The outer side of the left positioning block 1 has a contour-machining surface 12. The outer side of the left positioning block 1 has a special-shaped hole that mates with the workpiece 10 for positioning the workpiece 10. During installation, the contour-machining surfaces 11, 22, 3, and 4 can fit against the inner wall of the workpiece 10, which can effectively avoid incorrect placement of the workpiece and prevent collision accidents caused by incorrect placement of the workpiece. The outer side of the right positioning block 6 has a contour-machining surface 11. Both contour-machining surfaces are also contour-machined according to the outer contour of the workpiece 10. The first contouring surface 11 fits against the upper right side of the interior of workpiece 10, and the second contouring surface 12 fits against the upper left side of the interior of workpiece 10, providing support. These four contouring surfaces allow for precise workpiece positioning, providing excellent support during the machining of the outer surface of workpiece 10 and preventing interference.
