Description

Technical Field

[0001] The utility model relates to the technical field of limiters, in particular to a grinding tool limiter. Background Art

[0002] In the existing grinding process, the tool stopper plays a vital role. It is mainly responsible for the clamping and fixing of the workpiece to ensure the stability and accuracy of the processing process. However, the traditional tool stopper usually requires the operator to manually operate to clamp and fix the workpiece when working. This manual operation method is not only inefficient, but also has certain operating errors and instability. In addition, when different surfaces of the workpiece need to be processed, the operator needs to repeatedly remove the workpiece from the stopper, reposition it and fix it again. This process is cumbersome and time-consuming, which seriously affects the processing efficiency. At the same time, for heavier workpieces, repeated manual fixation not only increases the labor intensity of the operator, but may also lead to safety risks during the operation, such as accidental falling off of the workpiece or injury to the operator.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model realizes automatic clamping of the workpiece through two clamping structures arranged symmetrically on the left and right, which not only greatly improves the processing efficiency, but also reduces the manual intervention of the operator, thereby reducing the operating error and improving the processing accuracy. Secondly, the rotating structure on the clamping structure can drive the rotating plate to rotate, so that the workpiece can be easily turned to different surfaces during the clamping process, which provides great convenience for continuous and multi-faceted grinding. This design significantly reduces the tedious process of the operator's repeated positioning and fixing of the workpiece, which not only improves the processing efficiency rate, and avoids slight changes in the position of the workpiece that may be caused by multiple fixations, further ensuring the machining accuracy. Furthermore, the utility model arranges a lifting cylinder and a support plate between the two clamping structures to form a liftable support table. This design enables the support table to be flexibly adjusted according to the height and shape of the workpiece, ensuring that the workpiece can be stably placed on the support table when not flipped. This not only avoids the risk of the workpiece sliding or moving due to instability during the grinding process, but also makes the clamping and fixing of the workpiece by the clamping structure more stable and reliable, thereby further ensuring the stability and safety of the grinding process.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3The utility model provides a grinding tool limiter, including a workbench 1, two clamping structures 2, a rotating shaft 3 and a rotating plate 4. The two clamping structures 2 are both arranged on the top of the workbench 1, and the two clamping structures 2 are arranged symmetrically. The clamping structure 2 includes a slide rail 21, a slider 22, a movable plate 23 and a cylinder 24. The slide rail 21 is arranged on the top of the workbench 1, and the slider 22 is slidably connected with the slide rail 21. The movable plate 23 is arranged on the top of the slider 22. The cylinder 24 is arranged on the top of the workbench 1, and the driving end of the cylinder 24 is connected to one side of the slider 22. Through the telescopic action of the cylinder 24, the slider 22 can be driven to move along the slide rail 21, and then the position of the movable plate 23 is adjusted to achieve clamping or releasing of the workpiece. The two movable plates 23 are both rotatably connected with the rotating shaft 3, and a rotating plate 4 is arranged at one end of the rotating shaft 3. The rotating shaft 3 can drive the rotating plate 4 to rotate through the movable plate 23, and a rotating structure 5 is arranged on the movable plate 23.

[0015] Specifically, the rotating structure 5 includes a bracket 51, a protective box 52, a worm 53, a motor 54 and a worm wheel 55. The bracket 51 is arranged on the side of the moving plate 23 away from the rotating plate 4. The protective box 52 is arranged on the outer top of the bracket 51. The two ends of the worm 53 are respectively rotatably connected to the top and the bottom of the bracket 51. The motor 54 is arranged in the protective box 52, and the driving end of the motor 54 is connected to one end of the worm 53. The worm wheel 55 is arranged on the rotating shaft 3. The worm 53 is driven to rotate by the rotation of the motor 54. The worm wheel 55 is arranged on the rotating shaft 3 and cooperates with the worm 53 to realize the rotation of the rotating shaft 3, thereby driving the rotating plate 4 and the workpiece to flip to different angles.

[0016] Specifically, an oil cylinder 6 is provided at the bottom of the workbench 1, and the driving end of the oil cylinder 6 moves through the workbench 1. A support plate 7 is provided at the driving end of the oil cylinder 6. The driving end of the oil cylinder 6 can drive the support plate 7 to rise and fall. The height and position of the support plate 7 can be adjusted to adapt to workpieces of different heights and shapes, ensuring that the workpiece can be stably placed on the support plate 7 when not flipped, thereby avoiding slipping or movement of the workpiece due to instability during the grinding process.

[0017] Specifically, a rubber pad 8 is provided on the rotating plate 4 , and the rubber pad 8 increases the friction between the rotating plate 4 and the workpiece.

[0018] Working principle: First, the height of the support plate 7 needs to be adjusted according to the size and shape of the workpiece. The oil cylinder 6 arranged at the bottom of the workbench 1 can drive the support plate 7 to rise and fall, thereby adjusting the height and position of the support plate 7. In this way, workpieces of different heights and shapes can be stably placed on the support plate 7, avoiding the risk of the workpiece slipping or moving due to instability during the grinding process. Next, the two clamping structures 2 will work together to automatically clamp the workpiece. The cylinder 24 in the clamping structure 2 drives the slider 22 to move along the slide rail 21 through a telescopic action, thereby adjusting the position of the moving plate 23. When the moving plate 23 moves to a suitable position, the cylinder 24 Stop the action. At this time, the workpiece is stably clamped between the moving plates 23 and can be processed. In order to perform multi-faceted grinding, it is first necessary to control the oil cylinder 6 to drive the support plate 7 to move downward to reserve enough space for the workpiece to flip. Then, the rotating structure 5 starts to work. The motor 54 in the rotating structure 5 drives the worm 53 to rotate, and cooperates with the worm gear 55 to realize the rotation of the shaft 3. This action enables the shaft 3 to drive the rotating plate 4 and the workpiece placed on the rotating plate 4 to flip to different angles, thereby meeting the needs of multi-faceted grinding. After the flip is completed, the support plate 7 is driven to return to its original position by controlling the oil cylinder 6 again to continue to support the workpiece. In this way, the workpiece can be subjected to the next round of grinding.
