Description

Technical Field

[0001] The utility model relates to the technical field of swivel grinding tools, in particular to a swivel grinding tool positioning device. Background Art

[0002] A rotary abrasive is a tool used for surface processing and grinding, commonly found in metalworking, woodworking, plastics processing, and other fields. It typically consists of a rotating grinding ring and a fixed support structure. The working principle of a rotary abrasive is to cut and grind the workpiece surface through the rotation of the grinding ring. To ensure the stability of the workpiece during the grinding process and prevent it from moving or rotating, thereby improving processing accuracy and consistency, a rotary abrasive positioning fixture is required.

[0003] There are several types of positioning fixtures for rotating abrasives, including mechanical fixtures, pneumatic fixtures, and hydraulic fixtures. Each type of fixture has its own advantages in terms of application scenarios and processing requirements. Choosing the appropriate type based on actual processing requirements can effectively improve the processing quality and efficiency of rotating abrasives. Mechanical fixtures use mechanical structures such as clamps, threaded rods, or clamping devices to secure the rotating abrasive in the processing position. This type of fixture is simple and reliable, and is suitable for fixing rotating abrasives with relatively regular shapes.

[0004] However, there is a significant problem with the existing rotating ring mold positioning fixture in actual application, that is, when positioning workpieces of different specifications, the operator needs to manually adjust the position of the fixture frequently to ensure that the workpiece is fixed. The operator often manually loosens and adjusts the limit blocks or clamping parts of the fixture to match the size of the workpiece, and then retightens it to ensure that the workpiece does not loosen during the operation of the mold. This adjustment process is not only time-consuming, but also requires the operator to have a certain amount of experience to accurately adjust the angle and position of the fixture. Especially when faced with workpieces of different specifications or shapes, this adjustment needs to be repeated, resulting in reduced work efficiency. In addition, due to the complexity of manual adjustment, positioning errors are prone to occur, affecting the accuracy and consistency of processing. The cumbersome and time-consuming nature of this adjustment process increases the operating burden of workers, reduces the operational flexibility of the equipment, limits the ease of use of existing positioning fixtures, and further affects the overall efficiency of the production line.

A connecting plate 3 is provided on one side of the connecting plate 2 16. 21, the connecting plate three 21 cooperates with the limit groove 2 19 through its internal guide column 23 to ensure that it can slide stably and drive the tooth block 22 to reset when needed. The guide column 23 plays a role in stabilizing the connecting plate three 21, so that it can slide smoothly in the limit groove 2 19. The connecting plate three 21 is fixedly connected with the guide column 23 to ensure smooth sliding between the connecting plate three 21 and the limit groove 2 19. A tooth block 22 is fixedly connected to one side of the connecting plate three 21. The tooth block 22 is embedded in the card slot 17 to achieve locking and fixing of the workpiece during operation. The internal rotation of the connecting plate two 16 It is dynamically connected to the outer wall of the limit ring 20. The function of the limit ring 20 is to limit the rotation range of the connecting plate 2 16 to ensure that it can rotate freely within a reasonable range. The reset component includes a spring 24. The spring 24 is sleeved on the outer wall of the connecting shaft 18. The function of the spring 24 is to provide a reset force for the connecting plate 3 21.

One end of the spring 24 is fixedly connected to one side of the connecting plate 14, and the other end is fixedly connected to the other side of the connecting plate 3 21 to ensure that the transmission of the reset force can effectively act on the connecting plate 3 21;

[0036] Specifically, when it is necessary to adjust the angle of the fixed plate 2, first easily separate the connecting plate three 21 from the connecting plate two 16, and then rotate the fixed plate 2 with the connecting shaft 18 as the center through the connecting plate one 14. At this time, the connecting shaft 18 is precisely limited in the connecting plate two 16 by the limiting ring 20 to ensure stability during the rotation process. After adjusting to the required angle, release the connecting plate three 21, and the connecting plate three 21 automatically resets under the tension of the spring 24. The tooth block 22 on one side of the connecting plate three 21 is accurately re-embedded in the card slot 17 to complete the locking of the connecting shaft 18. At the same time, the connecting plate three 21 is slid and limited in the limiting slot two 19 by the guide column 23 to ensure the stability and accuracy of the connecting plate three 21. Through this design, the angle of the fixed plate 2 can be quickly adjusted and stably locked, which improves the convenience and reliability of the operation of the device.

[0037] Working principle: When using the rotating abrasive tool positioning fixture, first place the workpiece to be positioned on the placement plate 8, then the output end of the motor 6 drives the worm 7 to rotate, so that the worm 7 drives the placement plate 8 to rotate through the worm gear 9, and the placement plate 8 is limited in the installation groove 5. Then, when the placement plate 8 rotates, it drives the clamping block 12 to rotate through the rotating shaft 13 as the center of the circle. The outer wall of the clamping block 12 is connected to the slider 10 through the connecting rod 11 and is limited in the limiting groove 4. Therefore, the clamping block 12 rotates eccentrically with the rotating shaft 13 as the center of the circle, thereby positioning and clamping the workpiece, achieving the effect of quickly clamping and positioning the workpiece. When the angle needs to be adjusted, it is only necessary to separate the connecting plate three 21 from the connecting plate two 16, and then rotate the fixed plate 2 through the connecting plate one 14 with the connecting shaft 18 as the center of the circle. The connecting shaft 18 is limited in the connecting plate two 16 by the limiting ring 20. Then, after adjusting it into place, release the connecting plate three 21, so that the connecting plate three 21 drives the connecting plate three 21 to reset through the spring 24, and the tooth block 22 on one side of the connecting plate three 21 is re-embedded in the card slot 17 to lock the connecting shaft 18. At the same time, the connecting plate three 21 is slid and limited in the limiting slot two 19 by the guide column 23, thereby achieving the effect of adjusting the angle of the fixed plate 2.
