[0002] Nuts, also known as nuts, are parts that are screwed together with bolts or screws for fastening. During the processing of nuts, a series of processing steps are required, such as grinding right-angle edges, punching, threading or cutting. Among them, a clamping device is required when processing nuts. The clamping device not only improves the stability during processing, but also improves the processing efficiency.

[0003] Publication number CN220112806U discloses a nut processing clamping device, wherein a fixing mechanism is provided at the bottom of the fixing seat, and the clamping mechanism includes a clamping unit, a rotating unit, and a locking unit. The clamping unit is provided at the top of the fixing seat, the rotating unit is provided at the top of the clamping unit, and the locking unit is provided on the left side of the rotating unit. The clamping unit includes a motor, a screw, a clamping arm 1, and a clamping arm 2. The motor is fixedly connected to the middle of the right side of the fixing seat, and the screw is fixedly connected to the left end of the output shaft of the motor. The nut processing clamping device, by providing a locking unit in the middle of the fixed shaft of the rotating unit, can lock the gear in the middle of the fixed shaft through the locking teeth of the locking rod, thereby locking the position of the nut after rotation adjustment, thereby ensuring that the nut can remain stable during processing and ensuring the processing quality.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figures 1-4 As shown, the utility model provides a technical solution: a nut processing clamping device, including an operating table 1, a first mounting seat 2 and a second mounting seat 3, the top of the operating table 1 is fixedly connected to a fixing plate 11, the side of the fixing plate 11 is fixedly connected to a guide rod 12, the surface of the guide rod 12 is movably sleeved with a spring 13, the first mounting seat 2 and the second mounting seat 3 have the same structure and opposite directions, the first mounting seat 2 and the second mounting seat 3 are both slidably mounted on the surface of the guide rod 12, the side surfaces of the first mounting seat 2 and the second mounting seat 3 are respectively fitted with the two ends of the spring 13, a clamping block 4 is provided on one side of the first mounting seat 2, and the operating A driving motor 5 is fixedly installed on one side of the outer wall of the working table 1, and a first cam 6 and a second cam 7 are movably installed on the top of the operating table 1. Two movable plates 8 are provided inside the first mounting seat 2. The side of the first cam 6 is in contact with one side of the first mounting seat 2. The bottom of the first cam 6 is fixedly connected to a connecting rod 61, which is movably installed inside the operating table 1. A worm gear 62 is fixedly installed on the surface of the connecting rod 61. The output end of the driving motor 5 is fixedly connected to the mounting shaft 51, and a worm 52 is fixedly installed on the surface of the mounting shaft 51. The side of the worm 52 is engaged with the side of the worm gear 62.

[0025] In this embodiment, the nut is placed between the first mounting seat 2 and the second mounting seat 3, and then the driving motor 5 is started to drive the mounting shaft 51 and the worm 52 to rotate. The worm 52 and the worm wheel 62 engage with each other, so that the connecting rod 61 and the first cam 6 rotate together, and the second cam 7 is the same. The first cam 6 and the second cam 7 rotate at the same time, respectively squeezing the sides of the first mounting seat 2 and the second mounting seat 3, so that the first mounting seat 2 and the second mounting seat 3 are close to each other, and the first mounting seat 2 and the second mounting seat 3 slide on the surface of the guide rod 12 to squeeze the spring 13. At this time, the clamping blocks 4 on the sides of the first mounting seat 2 and the second mounting seat 3 move simultaneously to clamp and fix the nut, and when the driving motor 5 continues to rotate to reset the first cam 6 and the second cam 7, the spring 13 rebounds to move the first mounting seat 2 and the second mounting seat 3 away from each other, releasing the limit on the nut, thereby facilitating the fixing and disassembly of the nut.

[0026] Example 2

[0027] like Figures 1-4As shown, one side of the clamping block 4 is fixedly connected to a positioning block 41, a through hole 411 is provided on the surface of the positioning block 41, an engaging groove 201 is provided on one side of the first mounting seat 2, a card slot 202 is provided on the top of the first mounting seat 2, a turning handle 21 is movably installed on the top of the first mounting seat 2, and a gear 22 is fixedly connected to the bottom of the turning handle 21, a slide rod 23 is fixedly installed inside the first mounting seat 2, and a spring 24 is movably sleeved on the surface of the slide rod 23, and the movable plate 8 is fixedly connected to a clamping block 81 at one end near the card slot 202, and the movable plate 8 is fixedly connected to a slider 82 at one end near the slide rod 23, and the slider 82 is slidably installed on the surface of the slide rod 23, and a tooth groove 83 is provided on the side of the movable plate 8, and the side of the movable plate 8 is engaged with the teeth at one end of the gear 22.

[0028] In this embodiment, when nuts of different sizes need to be clamped, the gear 22 is driven to rotate by turning the handle 21, and the gear 22 engages with the side of the movable plate 8, thereby driving the movable plate 8 to move, and the slider 82 at one end of the movable plate 8 squeezes the spring 24 at one end of the surface of the slide rod 23. At this time, the movable plate 8 drives the clamping block 81 to retract into the first mounting seat 2, and one end of the clamping block 81 falls off from the inside of the through hole 411, releasing the limit on the positioning block 41, replacing the clamping block 4 of the corresponding size, and inserting its positioning block 41 into the inside of the card slot 202. Loosening the handle 21 allows the spring 24 to rebound, thereby resetting the position of the movable plate 8, and the clamping block 81 is re-embedded into the inside of the through hole 411, and the clamping block 4 can be installed.

[0029] The working principle of this embodiment is: the nut is placed between the first mounting seat 2 and the second mounting seat 3, and then the driving motor 5 is started to drive the first cam 6 and the second cam 7 to rotate together, respectively squeezing the sides of the first mounting seat 2 and the second mounting seat 3 so that the first mounting seat 2 and the second mounting seat 3 are close to each other. At this time, the clamping blocks 4 on the sides of the first mounting seat 2 and the second mounting seat 3 move simultaneously to clamp and fix the nut. When nuts of different sizes need to be clamped, the gear 22 is driven to rotate by turning the handle 21, and the rotation of the gear 22 drives the movable plate 8 to retract into the first mounting seat 2, and one end of the clamping block 81 falls off from the inside of the through hole 411, releasing the limit on the positioning block 41, replacing the clamping block 4 of the corresponding size, inserting its positioning block 41 into the inside of the card slot 202, loosening the handle 21 to make the spring 24 rebound, and the clamping block 81 is re-embedded into the inside of the through hole 411, and the clamping block 4 can be installed, which is convenient for replacing clamping blocks 4 of different sizes to clamp and fix the nuts.
