Description

Technical Field

[0001] This utility model relates to the field of ceramic chamfering processing technology, specifically a grinding device for processing the outer chamfer of ceramic chamfers. Background Technology

[0002] Ceramic chamfers are used as wire bonding tools in the wire bonding process. They can be used for bonding and packaging circuits such as silicon controlled rectifiers, surface acoustic waves, LEDs, diodes, transistors, and IC chips. When processing ceramic chamfers, their outer chamfers need to be ground.

[0003] An automatic feeding mechanism for chamfering ceramic chopping tools, patent number CN214292627U, is provided by setting up a base plate, a spindle sleeve, and a product spindle. One end of the product spindle is provided with a spindle chuck for clamping the ceramic chopping tool. A rotary motor is provided on one side of the product spindle on the base plate. A first moving component is provided on the base plate for driving the product spindle to move in the Y-axis direction. A second moving component is provided at the bottom of the base plate for driving the base plate to move in the X-axis direction.

[0004] However, research has shown that the aforementioned patents still have the following drawbacks:

[0005] The aforementioned automatic feed mechanism for chamfering ceramic wedges uses a belt mounted on a chuck to rotate the wedge. When the cylinder pushes the chuck to move, the belt tilts because the motor driving the belt does not follow its movement. This reduces the contact area between the belt and the chuck, thus decreasing the stability of the belt-driven chuck rotation. Furthermore, the aforementioned automatic feed mechanism for chamfering ceramic wedges cannot adjust the height of the wedge. Therefore, technological innovation and design optimization are needed to optimize the grinding device for chamfering ceramic wedges. Utility Model Content

[0006] The aforementioned automatic feed mechanism for chamfering ceramic wedges uses a belt mounted on a chuck to rotate the wedge. When the cylinder pushes the chuck to move, the belt tilts because the motor driving the belt does not follow, resulting in a smaller contact area between the belt and the chuck. This leads to decreased stability of the belt-driven chuck rotation. Furthermore, this automatic feed mechanism cannot adjust the height of the wedge. To address these issues, this application provides a grinding device for chamfering ceramic wedges. A gear drives a gear ring to rotate, which in turn drives a rotating column via a moving block. The rotating column then drives the chuck, which in turn drives the wedge. While the moving block drives the gear ring, it can slide within a moving groove, allowing the rotating column to slide within the gear ring while the gear ring drives the rotating column, effectively improving the stability of the rotating column. Additionally, the height of the top plate can be adjusted using a hydraulic cylinder and guide column to accommodate grinding machines of different heights.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A grinding device for chamfering ceramic cutting tools, comprising:

[0009] Grinding machine body;

[0010] A base plate is fixed to one side of the grinding machine body, and a top plate is provided on the top of the base plate. A lifting mechanism for raising and lowering the top plate is provided between the base plate and the base plate.

[0011] A movable plate is located on top of a top plate. A bushing is fixed on one side of the top of the movable plate. A chuck is provided inside the bushing. A sliding pushing mechanism that can drive the chuck to slide inside the bushing is installed on the top of the top plate. A rotating mechanism that can drive the chuck to rotate is provided on the top of the top plate.

[0012] A moving mechanism, located on one side of the top plate, is used to move the moving plate.

[0013] In one possible implementation, the lifting mechanism is fixed to a hydraulic cylinder on the top of the base plate. The output end of the hydraulic cylinder is fixed to the bottom of the top plate. A guide column is fixed to the bottom of the top plate. The bottom end of the guide column penetrates the base plate and can slide on the base plate. The hydraulic cylinder drives the top plate to move up and down. The sliding of the guide column on the base plate can improve the stability of the top plate when it moves and facilitate the adjustment of the height of the top plate so that the chopping blade can be at the same height as the grinding machine body.

[0014] In one possible implementation, the pushing mechanism includes a cylinder fixed to the top of the top plate, with a rotating column rotatably connected to the output end of the cylinder. The rotating column is fixedly connected to the chuck, and the cylinder pushes the rotating column to move. The rotating column pushes the chuck to slide inside the bushing, which facilitates the feeding of the chopping blade on the chuck into the grinding machine body for grinding.

[0015] In one possible implementation, the rotating mechanism includes a fixed block fixed to the top of the top plate, a rotating column passing through the fixed block, a gear ring rotatably connected to one side of the fixed block, the gear ring meshing with a gear, a motor fixed to the top of the top plate, the output end of the motor fixedly connected to the gear, a movable groove being formed on the rotating column, a movable block being fixed to the inner wall of the gear ring, the motor driving the gear to rotate, the gear driving the gear ring to rotate, the gear ring driving the rotating column to rotate via the movable block, the rotating column driving the chuck to rotate, and the chuck driving the chopping blade to rotate, facilitating grinding of the chopping blade in conjunction with the grinding machine body.

[0016] In one possible implementation, the rotating column can rotate and slide inside the fixed block, and the moving block can slide inside the moving groove. When the moving block drives the toothed ring to rotate, the moving block can slide inside the moving groove, which facilitates the rotating column to rotate while the toothed ring drives the rotating column to rotate, and the rotating column can slide inside the toothed ring.

[0017] In one possible implementation, the moving mechanism includes a rectangular groove formed on one side of the top plate, an L-shaped plate sliding inside the rectangular groove, a lead screw installed inside the rectangular groove, one end of the lead screw passing through the L-shaped plate and rotatably connected to the inner wall of the rectangular groove, a second motor fixed to one side of the top plate, the output end of the second motor passing through the top plate and fixedly connected to the other end of the lead screw, the L-shaped plate being fixedly connected to the moving plate, the second motor driving the lead screw to rotate, the lead screw driving the L-shaped plate to move, and the L-shaped plate driving the moving plate to move, facilitating the movement of the chopping blade to a position aligned with the grinding machine body.

[0018] In one possible implementation, a sliding groove is provided on the top of the top plate, and a sliding block slides inside the sliding groove. The top of the sliding block is fixedly connected to the bottom of the moving plate. When the moving plate moves, it can drive the sliding block to slide inside the sliding groove, which helps to improve the stability of the moving plate when it moves.

[0019] In one possible implementation, the bottom of the base plate is fixed with support legs at each of the four corners to facilitate support of the base plate.

[0020] In summary, this utility model has at least one of the following beneficial technical effects:

[0021] 1. The gear drives the gear ring to rotate, and the gear ring drives the rotating column to rotate through the moving block. The rotating column drives the chuck to rotate, and the chuck drives the chopping cutter to rotate.

[0022] 2. The height of the top plate can be adjusted by setting hydraulic cylinders and guide columns, making it easy to adapt to grinding machines of different heights. Attached Figure Description

The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] This embodiment describes the specific structure of a grinding device for chamfering ceramic cutting tools, as detailed in the following reference. Figures 1-5 As shown, a grinding device for chamfering ceramic cutting tools includes:

[0031] Grinding machine body 7;

[0032] The base plate 1 is fixed to one side of the grinding machine body 7. The top plate 2 is provided on the top of the base plate 1. A lifting mechanism for raising and lowering the top plate 2 is provided between the base plate 1 and the base plate 1.

[0033] The movable plate 11 is located on the top of the top plate 2. A bushing 6 is fixed on one side of the top of the movable plate 11. A clamp 16 is provided inside the bushing 6. A sliding pushing mechanism that can drive the clamp 16 to slide inside the bushing 6 is installed on the top of the top plate 2. A rotating mechanism that can drive the clamp 16 to rotate is provided on the top of the top plate 2.

[0034] The moving mechanism is located on one side of the top plate 2 and is used to move the moving plate 11.

[0035] Since the height of the grinding machine body 7 is different from the height of the chuck 16, the height of the chuck 16 needs to be adjusted to accommodate grinding machine bodies 7 of different heights.

[0036] The lifting mechanism is fixed to the top of the base plate 1 by a hydraulic cylinder 23. The output end of the hydraulic cylinder 23 is fixed to the bottom of the top plate 2.

The hydraulic cylinder 23 drives the top plate 2 to rise and fall. The sliding of the guide column 10 on the base plate 1 can improve the stability of the top plate 2 when it moves and facilitate the adjustment of the height of the top plate 2 so that the chopping blade can be consistent with the height of the grinding machine body 7.

[0037] After installing the chopping cutter onto the chuck 16, the chopping cutter needs to be moved to the alignment position with the grinding device body.

[0038] The moving mechanism includes a rectangular groove 19 on one side of the top plate 2. An L-shaped plate 15 slides inside the rectangular groove 19. A lead screw 14 is installed inside the rectangular groove 19. One end of the lead screw 14 passes through the L-shaped plate 15 and is rotatably connected to the inner wall of the rectangular groove 19. A second motor 8 is fixed on one side of the top plate 2. The output end of the second motor 8 passes through the top plate 2 and is fixedly connected to the other end of the lead screw 14. The L-shaped plate 15 is fixedly connected to the moving plate 11.

[0039] The top plate 2 has a sliding groove 12, and a sliding block 13 slides inside the sliding groove 12. The top of the sliding block 13 is fixedly connected to the bottom of the moving plate 11. When the moving plate 11 moves, it can drive the sliding block 13 to slide inside the sliding groove 12, which can improve the stability of the moving plate 11 when it moves.

The rotating column 17 is fixedly connected to the chuck 16. The cylinder 3 pushes the rotating column 17 to move, and the rotating column 17 pushes the chuck 16 to slide inside the bushing 6, so as to send the cutting tool on the chuck 16 into the grinding machine body 7 for grinding.

[0042] When grinding the chopping blade, it is necessary to ensure that the chopping blade rotates so that the grinding machine body 7 can grind the outer chamfer of the chopping blade.

[0044] The rotating column 17 can rotate and slide inside the fixed block 4, and the moving block 22 can slide inside the moving groove 21. When the moving block 22 drives the toothed ring 18 to rotate, the moving block 22 can slide inside the moving groove 21, so that while the toothed ring 18 drives the rotating column 17 to rotate, the rotating column 17 can slide inside the toothed ring 18.

[0045] In addition, support legs 9 are fixed at the four corners of the bottom of the base plate 1 to facilitate support of the base plate 1.

[0046] Among them, the model of the grinding machine body 7 is Zhengjia Automatic Outer Diameter Grinding Machine.

[0047] When the worker needs to grind the chopping knife, first activate the hydraulic cylinder 23 to raise the top plate 2 to the same height as the grinding machine body 7, install the chopping knife into the chuck 16, activate the second motor 8, the second motor 8 moves the moving plate 11 to the position aligned with the grinding machine body 7, activate the cylinder 3 and the first motor 5, the motor drives the rotating column 17 to rotate, the rotating column 17 drives the chopping knife to rotate through the chuck 16, the cylinder 3 drives the rotating column 17 to drive the chuck 16 to send the chopping knife into the grinding machine body 7 for grinding, after grinding is completed, the operation is reversed to remove the chopping knife.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation.
