[0022] The utility model will be further described below in combination with the drawings.

[0023] As attached Figures 1 to 5 A kind of clamping device of rotary clamping, including support 1 and clamping table 2. Clamping table 2 is provided with workpiece clamping mechanism, can be clamped on clamping table 2. One side of clamping table 2 is connected with rotating shaft 3, rotating hole is provided on support 1, rotating shaft 3 is correspondingly inserted in rotating hole, clamping table 2 is rotatably installed on support 1 by rotating shaft 3, so that the angle of workpiece can also be rotated to adjust the workpiece that clamping table 2 clamps.

[0024] As attached Figure 1 In rotating shaft 3, there are several clamping grooves 4 in ring direction, specifically, there is disc-shaped part on rotating shaft 3, and clamping groove 4 is arranged on the disc-shaped part of rotating shaft 3. Lifting column 5 is installed on support 1, and lifting column 5 can be lifted relative to support 1. Clamping piece 6 is connected to lifting column 5, when lifting column 5 is lifted, lifting column 5 can drive clamping piece 6 to enter and exit clamping groove 4. When clamping piece 6 enters clamping groove 4, the rotation of rotating shaft 3 is limited, and the angle of clamping table 2 is limited, so that the workpiece clamped on clamping table 2 can be limited to the required angle, which is convenient for operation. When the angle of workpiece needs to be adjusted, the clamping groove 4 matched with clamping piece 6 is changed.

[0025] As attached Figure 2 And 4 As shown in the drawings, hollow lifting channel is arranged in support 1, the lifting channel is vertical channel, the lifting channel is located below rotating shaft 3, and lifting column 5 is correspondingly installed in the lifting channel, so that lifting column 5 can be lifted in the lifting channel.

[0026] The first elastic member is arranged in the lifting channel. In one embodiment, the first elastic member is a telescopic spring, and the first elastic member is located at the bottom of the lifting channel. The upper end of the first elastic member is connected with the bottom of the lifting column 5. The elastic effect of the first elastic member has a tendency to drive the lifting column 5 to rise. The lifting column 5 is further connected with a pressing rod 7, and one end of the pressing rod 7 extends out of the lifting channel. When the pressing rod 7 is pressed, the lifting column 5 is driven to move downward, and the clamping part 6 moves downward to be separated from the clamping groove 4. At this time, the rotating clamping table 2 can be rotated. When the pressing rod 7 is released, the lifting column 5 moves upward under the elastic effect of the first elastic member. The clamping part 6 is located on the outer contour of the rotating shaft 3. Then, the rotating shaft 3 is rotated to another clamping groove 4 opposite to the clamping part 6. The clamping part 6 is inserted into the clamping groove 4 to limit the rotating shaft 3 from continuing to rotate. The clamping part 6 is in the form of a plate. The clamping part 6 can be inserted into the clamping groove 4.

[0027] The lifting column 5 is provided with an upper through hole and a lower through hole. The upper through hole and the lower through hole penetrate the lifting column 5 along the horizontal direction. Figure 4 As shown in the drawings, one end of the pressing rod 7 is hinged in the lifting channel. The other end of the pressing rod 7 extends out of the lifting channel through the lower through hole. The end of the pressing rod 7 extending out of the lifting channel is provided with a pressing plate. The worker can press the pressing rod 7 through the pressing plate, so as to drive the lifting column 5 to move downward in the lifting channel. One end of the clamping part 6 is hinged in the lifting channel. The other end of the clamping part 6 extends out of the lifting channel through the upper through hole. Therefore, when the lifting column 5 moves downward, the lifting column 5 drives the clamping part 6 to swing downward, so that the clamping part 6 is separated from the clamping groove 4. At this time, the rotating shaft 3 can be rotated. Correspondingly, the clamping table 2 can be adjusted in angle. When the worker releases the pressing plate, the clamping part 6 swings upward under the elastic effect of the first elastic member. If the rotating shaft 3 is rotated to a certain clamping groove 4 opposite to the clamping part 6, the clamping part 6 swings upward to be inserted into the clamping groove 4, so as to limit the clamping table 2 at a certain angle, and hinder the clamping table 2 from continuing to rotate, so as to facilitate the worker to assemble the clamping table 2.

[0028] The clamping table 2 is fixedly provided with a fixed clamping plate 8. The bottom of the clamping table 2 is provided with a sliding channel. The workpiece clamping mechanism comprises a lower sliding plate 9. The lower sliding plate 9 is fixedly provided with an outer clamping plate 10. One side of the outer clamping plate 10 is connected with a push-pull handle 25. The outer clamping plate 10 is opposite to the fixed clamping plate 8. The push-pull handle 25 is located on the side of the outer clamping plate 10 away from the fixed clamping plate 8. The push-pull handle 25 can push and pull the lower sliding plate 9, so that the lower sliding plate 9 slides along the sliding channel, and the outer clamping plate 10 approaches or moves away from the fixed clamping plate 8 to perform clamping or releasing action, so as to clamp or release the workpiece.

[0029] The clamping platform 2 is also provided with a second elastic element 11. Under the elastic action of the second elastic element 11, the outer clamping plate 10 tends to move away from the fixed clamping plate 8. The clamping platform 2 is also provided with a locking mechanism and an unlocking mechanism. The locking mechanism can lock the lower slide plate 9, keeping the outer clamping plate 10 and the fixed clamping plate 8 in a close-to-each-other state. The unlocking mechanism can release the locking mechanism from locking the lower slide plate 9.

[0030] At least one inner clamping plate 12 is also provided between the outer clamping plate 10 and the fixed clamping plate 8. The lower part of the inner clamping plate 12 is connected to the upper sliding plate 24, which can slide on the lower sliding plate 9. Workpieces can be clamped between adjacent outer clamping plates 10, inner clamping plates 12 or fixed clamping plates 8. By providing the inner clamping plate 12, multiple workpieces can be clamped on the clamping table 2 at the same time, thereby improving the assembly efficiency of the workpieces.

[0031] As attached Figure 2 As shown, a guide rod is provided on the side of the outer clamping plate 10 facing the fixed clamping plate 8, and a guide hole is provided on the clamping platform 2. The guide rod slides in conjunction with the guide rod to restrict the movement direction of the outer clamping plate 10. A through hole is opened in the upper sliding plate 24, and the guide rod passes through the corresponding through hole of the upper sliding plate 24, so that the upper sliding plate 24 can slide on the lower sliding plate 9. The second elastic element 11 is a spring sleeved on the guide rod, and the second elastic element 11 is located between the fixed clamping plate 8 and the inner clamping plate 12.

[0032] As attached Figure 2 and 3 As shown, the clamping platform 2 is provided with a locking channel, which is a vertical channel, and its lower end is connected to a sliding channel. The locking mechanism includes a locking pin 13 disposed in the locking channel. The locking pin 13 can move up and down within the locking channel. The upper end of the locking pin 13 is connected to a third elastic element 14, and the lower end of the locking pin 13 is provided with a locking tooth 15. A locking groove 16 is provided on the lower slide plate 9 near the locking channel. When the locking groove 16 moves with the lower slide plate 9 to below the locking tooth 15, the elastic action of the third elastic element 14 can push the locking tooth 15 into the locking groove 16, thereby locking the lower slide plate 9 and keeping the outer clamping plate 10 and the fixed clamping plate 8 in a close-to-each-other state.

[0033] The unlocking mechanism includes a pusher post 17, one end of which is provided with a pusher ramp. The locking post 13 is provided with a force-receiving ramp, which is opposite to the pusher ramp. The pusher post 17, through the cooperation of the pusher ramp and the force-receiving ramp, can push the locking post 13 upwards, causing the locking teeth 15 to move out of the locking slot 16, thereby releasing the lock on the lower slide plate 9. After the locking teeth 15 move out of the locking slot 16, under the action of the second elastic element 11, the outer clamping plate 10 will move away from the fixed clamping plate 8, releasing the clamped workpiece.

[0034] The rotating shaft 3 is provided with a hollow pushing channel, the pushing channel is a horizontal channel, the pushing column 17 is correspondingly installed in the pushing channel, and the pushing column 17 can move horizontally in the pushing channel. The end of the pushing column 17 away from the pushing inclined surface extends out of the pushing channel, so that the worker can control the horizontal movement of the pushing column 17 in the pushing channel.

[0035] As shown in the accompanying drawings, Figure 2 and 5 The pressing handle 18 is hingedly installed on the support 1, and the pressing inclined surface 23 is arranged on the pressing handle 18. The end of the pushing column 17 extending out of the pushing channel is provided with a pressure receiving tapered surface 22, and the pressure receiving tapered surface 22 is correspondingly located below the pressing inclined surface 23. When the pressing handle 18 is pressed downward, the pressing inclined surface 23 falls on the pressure receiving tapered surface 22 to push the pushing column 17 to move towards the locking column 13. The pushing column 17 pushes the locking column 13 to move upward through the cooperation of the pushing inclined surface and the stress inclined surface, and the locking column 13 moves upward to compress the third elastic member 14. When the pressing handle 18 swings upward to be away from the pressure receiving tapered surface 22, the locking column 13 moves downward under the elastic action of the third elastic member 14, and then pushes the pushing column 17 to move away from the locking column 13.

[0036] As shown in the accompanying drawings, Figure 2 The end of the pushing column 17 extending out of the pushing channel is provided with a ring groove 19. The pressure receiving tapered surface 22 is provided with a fool-proof groove 20 extending along the length direction of the pushing column 17, one end of the fool-proof groove 20 communicates with the ring groove 19, and the other end of the fool-proof groove 20 extends to the end of the pushing column 17. The support 1 is provided with a fool-proof pin 21, and the fool-proof pin 21 is correspondingly clamped in the ring groove 19. When the fool-proof pin 21 is not aligned with the fool-proof groove 20, the fool-proof pin 21 will hinder the pushing column 17 from moving towards the locking column 13. Only when the fool-proof pin 21 is aligned with the fool-proof groove 20, the pushing column 17 is pushed towards the locking column 13, and then the workpiece on the clamping table 2 is released. Therefore, through the cooperation of the fool-proof pin 21 and the fool-proof groove 20, the clamping table 2 can only release the workpiece when it is rotated to a specific angle, so that the workpiece is prevented from falling from the clamping table 2 due to the accidental touch of the pushing column 17.

[0037] The working mode of the utility model is described in combination with the accompanying drawings:

[0038] When it is necessary to clamp a workpiece, one workpiece is placed between the outer clamping plate 10 and the inner clamping plate 12, and then another workpiece is placed between the inner clamping plate 12 and the fixed clamping plate 8. Then the worker pushes the push-pull handle 25 by hand, so that the lower sliding plate 9 slides in the clamping table 2 until the locking clamping groove 16 on the lower sliding plate 9 is moved below the locking clamping tooth 15. Under the elastic action of the third elastic member 14, the locking clamping tooth 15 is pushed into the locking clamping groove 16, so as to lock the lower sliding plate 9, and the clamping of the workpiece is completed.

[0039] When the workpiece needs to be rotated, the worker presses the pressing rod 7 to make the lifting column 5 move downward, and then drives the clamping part 6 to swing downward, so that the clamping part 6 is separated from the clamping groove 4, at this time the rotating shaft 3 can be rotated; then the worker holds the push-pull handle 25 to drive the workpiece on the clamping table 2 to rotate, and releases the pressing rod 7, under the elastic action of the first elastic part, the clamping part 6 will swing upward, if the rotating shaft 3 rotates to a certain clamping groove 4 opposite to the clamping part 6, the clamping part 6 will swing upward to be inserted into the clamping groove 4, so as to limit the clamping table 2 at a certain angle, and the workpiece is also limited at the required angle; as shown in the accompanying drawings, the workpiece needs to be assembled with bolts at both ends, and the workpiece can be rotated by 180 degrees to assemble the other end of the workpiece. Figure 1

[0040] When the workpiece needs to be removed, the worker swings the pressing handle 18 downward to press the pressing handle 18 on the push-up column 17, drives the push-up column 17 to displace towards the locking column 13, and then drives the locking column 13 to move upward, when the locking column 13 moves upward, the third elastic part 14 is compressed, so that the locking tooth 15 moves out of the locking clamping groove 16, thereby releasing the locking of the sliding plate 9; after the locking tooth 15 moves out of the locking clamping groove 16, the outer clamping plate 10 will displace towards the direction away from the fixed clamping plate 8 due to the action of the second elastic part 11, and the clamped workpiece is released, at this time the workpiece can be removed.

[0041] The above is only the preferred embodiment of the present application, it should be pointed out that: for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.​
