[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 1 、 Figure 3 and Figure 4The cam 8 is fixed on the top of the cam 8 and is connected with the upper end of the cam 8, so that the cam 8 can be fixed on the top of the cam 8 and the lower end of the cam 8 is fixed on the top of the cam 8. The outside of the mounting box 3 is fixedly connected to a cylinder 4, the end of which is fixedly connected to a rack 11, which is slidably connected to the inside of the mounting box 3. The inside of the ratchet 8 is fixedly connected to a rotating shaft 14. The top of the rack 11 is rotatably connected to a connecting rod 10, and the outside of the connecting rod 10 is fixedly connected to a gear 12. The outside of the rotating shaft 14 is fixedly connected to the middle part of the gear 12, and the gear 12 is clamped with the rack 11. When the cylinder 4 drives the rack 11 to extend outward, the gear 12 is driven to rotate, and the connecting rod 10 rotates with the gear 12, thereby driving the block 9 outside the connecting rod 10 to push the ratchet 8 to rotate under the action of the rack 11. The block 9 is limited by the limit block 7 to prevent the rack 11 from driving the block 9 to disengage from the ratchet 8. The cylinder 4 drives the rack 11 to retract inward while driving the gear 12 to rotate in the opposite direction. At the same time, the connecting rod 10 and the block 9 rotate in the opposite direction with the gear 12, and the ratchet 8 is rotated intermittently, thereby adjusting the angle of the workpiece on the turntable 1 to avoid damage to the equipment caused by the workpiece falling off during processing, causing personal injury to the operator, facilitating precise processing of the workpiece, and improving processing accuracy and processing efficiency. A fixing rod 13 is fixedly connected to the middle of the installation box 3. By using the fixing rod 13, the stability of the equipment during use is increased. The rotating shaft 14 is rotatably connected to the outside of the fixing rod 13, and the rotation is used to drive the gear 12 and the ratchet 8 to rotate.
[0033] Reference Figure 1 and Figure 2The clamping assembly includes a clamping block 2, the outer portion of which is slidably connected to the middle portion of the turntable 1. The clamping block 2 can be used to clamp the workpiece to be processed, keeping the workpiece stable on the workbench, facilitating the next step of processing, and ensuring the quality of the workpiece. The bottom of the turntable 1 is fixedly connected to a fixed plate 6, and the top of the fixed plate 6 is fixedly connected to a leaf spring 5. The use of the leaf spring 5 greatly improves the clamping speed, thereby improving the production efficiency of the entire processing process. The clamping block 2 is placed on the outside of the leaf spring 5. Under the action of the leaf spring 5, the clamping block 2 is driven to slide inside the slide groove 15. The workpiece is fixed according to the appropriate size. Multiple clamping blocks 2 can clamp the workpiece, which can more effectively reduce eccentricity and tilt during the clamping process, thereby significantly improving the accuracy of the workpiece. A slide groove 15 is provided in the middle of the turntable 1, and the clamping block 2 is slidably connected inside the slide groove 15.
[0034] Working principle: By starting the cylinder 4, the rack 11 is driven to reciprocate inside the installation box 3. Under the action of the rack 11, the gear 12 is driven to rotate. When the cylinder 4 drives the rack 11 to extend outward, the gear 12 is driven to rotate. The connecting rod 10 rotates together with the gear 12, thereby driving the block 9 outside the connecting rod 10 to push the ratchet 8 to rotate under the action of the rack 11. The block 9 is limited by the limit block 7 to prevent the rack 11 from driving the block 9 to separate from the ratchet 8. The cylinder 4 drives the rack 11 inward. While contracting, it drives the gear 12 to rotate in the opposite direction. At the same time, the connecting rod 10 and the block 9 rotate in the opposite direction with the gear 12, and the ratchet 8 rotates intermittently, thereby adjusting the angle of the workpiece on the turntable 1. Another set of blocks 9 are used to self-lock the ratchet 8, thereby increasing the processing accuracy, ensuring the performance and quality of the parts, and improving the practicality of the device, avoiding the turntable 1 driving the workpiece to rotate during processing, causing the workpiece to leave the workbench, causing damage to the workpiece and equipment, and endangering the personal safety of the operator.
[0035] Under the action of the leaf spring 5, the clamping block 2 is driven to slide inside the slide groove 15, which is convenient for fixing and clamping workpieces of different models, and giving the workpieces a clamping force to complete the clamping of the workpiece. The use of the leaf spring 5 greatly improves the clamping speed, thereby improving the production efficiency of the entire processing process and increasing the stability of the processing process, thereby realizing the selection of suitable sizes according to different workpieces, enabling the turntable 1 to drive the workpiece to achieve smooth and continuous rotation, meeting the requirements of processing efficiency.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
