Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding and processing technology, and in particular to a device for precise grinding of the parting line of electroplated parts. Background Technology
[0002] In the production process of electroplated parts, the various parts of the mold are spliced together to form a cavity for molding processes such as injection molding or die casting. When the molten material is injected into the cavity, a small amount of material may overflow at the joint of the mold due to factors such as material flow and pressure. After cooling, this forms the parting line. The parting line, also known as the overflow line, is the visible mark left after excess plastic flows out at the mold joint, even after the overflow is removed. Publication number CN220330889U discloses a stable clamping and polishing device for electroplated parts, relating to the field of polishing processing technology. This utility model relates to the field of polishing processing technology and discloses a stable clamping and polishing device for electroplated parts, including a base, a motor, and a polishing disc. The top of the base is equipped with a stable clamping mechanism; a fixing frame is fixedly mounted on the top of the base, and a first cylinder is fixedly mounted on the top of the fixing frame. A mounting plate is fixedly mounted on the end of the piston rod of the first cylinder. The motor is fixedly mounted on the lower surface of the mounting plate, and a hollow rotating shaft is fixedly mounted on the output end of the motor. The polishing disc is fixedly mounted on the lower end of the hollow rotating shaft, and an air outlet is opened at the center of the polishing disc. A hollow disc is provided on the shaft wall of the hollow rotating shaft, and an air inlet is opened on the shaft wall of the hollow rotating shaft. A blower is fixedly mounted on the side wall of the fixing frame, and the output end of the blower is fixedly connected to the hollow disc through a connecting pipe. This invention can continuously cool the grinding contact surface, avoiding the deformation of electroplated parts caused by heat generated from prolonged friction. At the same time, it can stably clamp the electroplated parts, improving the grinding accuracy. However, the workpiece is stationary during the grinding process. If different angles of the workpiece need to be ground, the workpiece position needs to be manually adjusted, which is cumbersome and inefficient. Improvement is needed. Utility Model Content

A lead screw 19 is fixedly installed at the output end of the servo motor 18. A support platform 20 is threadedly connected to the surface of the lead screw 19. A slide rod 21 is fixedly installed on the inner surface of the fixed frame 17. Driven by the servo motor 18, the support platform 20 moves smoothly along the slide rod 21 inside the fixed frame 17, thereby achieving precise grinding of the workpiece surface. The moving frame 6 is slidably connected to the grinding table 2, and the rotating block 11 is rotatably connected to the mounting block 8. The setting of the grinding table 2 provides stable support for the moving frame 6 when it moves, ensuring that the workpiece does not shift during the grinding process. The limiting block 15 is engaged with the limiting tooth 10. A cleaning groove is provided at the bottom of the grinding table 2. Through the engagement design of the limiting block 15 and the limiting tooth 10, the connecting rod 9 is effectively prevented from rotating excessively, ensuring grinding accuracy. The cleaning groove facilitates timely removal of grinding debris. The support platform 20 is slidably connected to the slide rod 21 and the fixed frame 17. Through the precise guidance of the slide rod 21, the movement of the support platform 20 is more stable, reducing vibration and improving grinding quality.
[0024] Example 2
[0025] Please see Figure 4 A first support column 22 is fixedly installed on the surface of the support platform 20. A spring 23 is fixedly installed on the surface of the first support column 22. A second support column 24 is fixedly installed at one end of the spring 23. A positioning column 25 and a mounting frame 26 are fixedly installed on the surface of the second support column 24. A second motor 27 is fixedly installed on the surface of the mounting frame 26. A grinding disc 28 is fixedly installed at the output end of the second motor 27. Through the buffering effect of the spring 23, the impact force during the grinding process can be effectively reduced, protecting the workpiece surface and improving the grinding accuracy. The positioning column 25 and the second support column 24 are slidably connected to the first support column 22. Through the design of the positioning column 25, the grinding disc 28 can be kept stable during the movement, reducing grinding errors and improving the overall processing efficiency.
[0026] Working principle: When using this device, the first motor 4 drives the double-headed threaded rod 5 to move the moving frame 6 inside the grinding table 2 to adjust it to the optimal grinding position of the workpiece. Then, the clamping plate 13 on the clamping cylinder 12 firmly fixes the workpiece to ensure that it does not shift during the grinding process. After that, the second motor 27 is started to drive the grinding disc 28 to rotate and grind. The grinding disc 28 will slowly contact the surface of the workpiece under the action of the telescopic rod 3, and then grind its surface. After that, the servo motor 18 drives the lead screw 19 to move smoothly along the slide rod 21 inside the fixed frame 17, so that the support table 20 drives the grinding disc 28 evenly. The surface of the workpiece is covered to ensure uniform and delicate grinding. During the grinding process, the second support column 24 and the positioning column 25 will adjust the pressure according to the feedback from the workpiece surface through the elasticity of the spring 23 to avoid over-grinding the workpiece. At the same time, the cleaning groove at the bottom of the grinding table 2 can discharge and clean debris in time. When different surfaces of the workpiece need to be ground, the adjustment handle 16 can be turned to drive the rotating block 11 to change the angle of the workpiece held by the clamping plate 13. When adjusted to the appropriate position, the threaded rod 14 is turned to drive the limiting block 15 to engage with the limiting teeth 10 on the surface of the connecting rod 9, thereby fixing the angle of the workpiece and ensuring the stability of the grinding process.
