Description

Technical Field

[0001] This utility model relates to the field of quartz irregular curved surface grinding technology, and in particular to a quartz irregular curved surface grinding machine. Background Technology

[0002] This is a tool for grinding irregular curved surfaces of quartz, such as when the surface of a quartz part is curved. Therefore, a grinding machine for quartz ceramic production, with publication number CN216681597U, has an irregularly shaped grinding surface. The grinding surface of the grinding disc is arranged in the following order from the center outward: convex, concave, and flat. A screw is mounted on the top of the motor via a bearing, and a turntable is mounted on the top of the screw. The screw is installed at the center of the top of the fixed frame and is threadedly connected to the fixed frame. The irregularly shaped grinding disc can grind convex, concave, and flat surfaces, greatly improving the applicability of the grinding disc. During grinding, the grinding disc can be moved to the appropriate height by rotating the screw to grind the required ceramic.

[0003] However, the dimensions and relative positions of the concave, convex, and flat areas on the surface of the grinding disc are fixed. This means that when the grinding disc grinds the flat part of the ceramic part, it can only operate within a limited area. If the grinding area of ​​the ceramic part is too large, the flat part of the grinding disc cannot completely cover the flat area of ​​the ceramic part, resulting in some areas not being effectively ground, or contact with the concave or convex surface of the grinding disc, producing an uneven grinding effect.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-5 As shown, a quartz irregular curved surface grinding machine includes a bed frame 1, a lifting frame 2 movably mounted above the bed frame 1, and the bed frame 1 is used to mount quartz parts. An annular rail 5, coaxially distributed with the bed frame 1, is fixedly mounted on the bottom surface of the lifting frame 2, and the bottom surface of the lifting frame 2 is located at the center of the annular rail 5. A horizontal swing arm 15, driven to rotate by a stepper motor, is rotatably connected to it. Figure 1As shown, by installing a stepper motor on the upper surface of the lifting frame 2, the main shaft of the stepper motor extends downward through the lifting frame 2 and is fixedly connected to one end of the horizontal swing arm 15. The top edge of the horizontal swing arm 15 is inserted into the annular rail 5, and the bottom edge of the horizontal swing arm 15 is inserted into a connecting seat 21 that slides along the radius of the annular rail 5. By driving the horizontal swing arm 15 to rotate on the surface of the annular rail 5 using the stepper motor, the corresponding connecting seat 21 can be made to revolve around the center of the annular rail 5. The bottom edge of the connecting seat 21 is rotatably connected to a linear module 14. A spur gear ring 19 located directly below the connecting seat 21 is fixedly installed on one end of the surface of the linear module 14, and a lower spur gear 18 driven by a motor and meshing with the spur gear ring 19 is provided inside the connecting seat 21. The slider part of the linear module 14 is set away from the connecting seat 21, and a downwardly extending electric push rod 16 is fixedly installed on the bottom edge of the slider part of the linear module 14. An electric grinder 22 is fixedly installed at the extension end of the electric push rod 16. Figure 3 As shown, the electric polisher 22 is located at one end of the linear module 14. Therefore, by using the connecting seat 21 to move within the horizontal swing arm 15, the linear module 14 can be moved synchronously, allowing the electric polisher 22 to move along the radius of the bed frame 1 and reach the edge of the bed frame 1. Thus, during the revolution of the connecting seat 21, the linear module 14 and the electric polisher 22 can be driven to revolve synchronously. In addition, the extension and retraction of the electric push rod 16 controls the raising and lowering of the electric polisher 22, which is convenient for polishing the convex or concave surfaces of the quartz part. Alternatively, by setting a motor in the connecting seat 21 to drive the spur gear 18 to rotate, the meshing spur gear ring 19 can be used to drive the linear module 14 to rotate at a certain angle to the horizontal swing arm 15. At this time, the movement of the slider in the linear module 14 and the extension and retraction of the electric push rod 16 facilitate the polishing of the convex or concave surfaces of the quartz part.

[0019] The electric grinder 22 is specifically the NSK Zhongxi EV410-230 electric grinder.

[0020] A horizontally arranged rack 20 is fixedly installed inside the horizontal swing arm 15. An upper spur gear 17, driven by a motor and meshing with the rack 20, is also installed inside the connecting seat 21. By installing a motor to drive the upper spur gear 17 to rotate, the upper spur gear 17 can roll on the surface of the rack 20 inside the horizontal swing arm 15 through the meshing connection, and the connecting seat 21 can slide along the surface of the horizontal swing arm 15. At least three vertically arranged lead screws 4 are fixedly installed on the bottom edge of the lifting frame 2. The lead screws 4 pass through the edge of the bed frame 1, and a loosening nut 3 is rotatably connected to one of the lead screws 4 through the upper surface of the bed frame 1. By rotating the loosening nut 3, the loosening nut 3 is threadedly connected to the corresponding lead screw 4, and the height of the lifting frame 2 can be adjusted by the constraint of the other lead screws 4 passing through the edge of the bed frame 1.

[0021] The upper surface of the bed frame 1 has several grooves 6 arranged in a circular array around the center of the annular rail 5. The grooves 6 are arranged along the radius of the annular rail 5, and two sliding blocks 7 are slidably installed within each groove 6. A connecting screw 13, passing through the lower opening of the groove 6, is fixedly installed on the bottom edge of each sliding block 7. A fastening nut 12 is threaded onto the connecting screw 13 to secure it against the bottom surface of the bed frame 1. By rotating the fastening nut 12, it is disengaged from the bottom surface of the bed frame 1, allowing the connecting screw 13 to move the sliding block 7 within the groove 6 to adjust its position. Then, by rotating the fastening nut 12 again to secure it against the bottom surface of the bed frame 1, the position of the sliding block 7 within the groove 6 is fixed. The sliding block 7 closest to the center of the annular rail 5 within the groove 6 supports the bottom surface of the quartz component, while the sliding block 7 furthest from the center of the annular rail 5 abuts against the edge of the quartz component. A through-hole coaxial with the connecting screw 13 is provided on the top edge of each sliding block 7. The long screw 11 with threaded penetration is fixedly installed with an anti-slip pad 10 at the top of the long screw 11 near the center of the annular rail 5 in the slide groove 6. The long screw 11 far from the center of the annular rail 5 in the slide groove 6 is threadedly connected with an upper washer 9 and a lower washer 8. The upper washer 9 and the lower washer 8 are both located above the sliding block 7 and are used to contact the upper and lower surface edges of the quartz piece respectively. The height of the anti-slip pad 10 can be adjusted by rotating the long screw 11 to adjust the level of the quartz piece. The length of the long screw 11 located above the bed frame 1 can be adjusted by rotating the long screw 11 on the outer sliding block 7. Then, the distance between the two can be adjusted by rotating the upper washer 9 and the lower washer 8 separately to adjust according to the edge thickness of the quartz piece. The lower washer 8 supports the bottom edge of the quartz piece, the upper washer 9 presses down on the upper surface edge of the quartz piece, and the long screw 11 on the outer sliding block 7 abuts against the edge of the quartz piece to fix the position of the quartz piece.

[0022] The method of using this utility model is as follows: The quartz part is fixed on the upper surface of the bed frame 1 using the sliding block 7. Then, the connecting seat 21 slides in the horizontal swing arm 15 to drive the linear module 14 to slide and adjust the horizontal distance between the electric grinder 22 and the center of the annular rail 5. The stepper motor drives the horizontal swing arm 15 to rotate, which drives the linear module 14 to revolve, thereby realizing the revolution of the electric grinder 22. In addition, the extension and retraction of the electric push rod 16 facilitates the grinding of the surface of the quartz part to form an upper convex surface or a lower concave surface. Alternatively, the linear module 14 drives the electric grinder 22 to move along a straight line. The lifting and lowering of the electric grinder 22 facilitates the grinding of the quartz part into different shapes.

[0023] The wiring diagrams of the stepper motor, motor, electric push rod 16, linear module 14 and electric grinder 22 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the stepper motor, motor, electric push rod 16, linear module 14 and electric grinder 22 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
