[0036] Please check Figure 1 and Figure 4 The limiting component 20 includes a ball valve 201 and a rotating rod 203. The two first connecting pipes 133 are rotatably connected to the inside of the ball valve 201. The two ball valves 201 are each provided with a through hole 202. The rear sides of the two ball valves 201 are each connected to the rotating rod 203 by welding. The two rotating rods 203 are rotatably connected to the adjacent first connecting pipes 133 and the shell 131.

[0037] When the device is needed, the two ball valves 201 are driven to rotate 90 degrees by the two rotating rods 203, so that the two through holes 202 are connected to the two first connecting pipes 133 respectively, and then the two plug covers 102 are removed from the two mounting blocks 10 respectively, and then oil is injected into the two mounting blocks 10, and the oil will enter the two oil chambers 101 respectively, and the oil will enter the two butt joints 132 respectively through the two second connecting pipes 134, and the oil in the two butt joints 132 will then enter the two housings 131 respectively through the two first connecting pipes 133 and the through holes 202. When the oil in the two oil chambers 101 is filled, the oil injection is stopped, and the two plug covers 102 are respectively covered on the two mounting blocks 10, and then the staff drives the bidirectional screw rod by rotating the rotating seat 5. 7, the first sliding frame 8, the swivel 9, the mounting block 10, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19, the limiting assembly 20 and the workpiece are rotated. When the workpiece is rotated to a suitable angle, the rotating seat 5 is stopped, so that the rotating seat 5 can be rotated to a suitable angle. Thereafter, the staff holds the workpiece by hand so that the workpiece is located between the rubber heads 12 on both sides, and then rotates the bidirectional screw rod 7. Under the action of the threaded cooperation between the bidirectional screw rod 7 and the two first sliding frames 8, the bidirectional screw rod 7 drives the swivel 9, the mounting block 10, the oil chamber 101, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19 and the limiting assembly on the two first sliding frames 8 respectively through the two first sliding frames 8. 20 moves in the directions toward each other, and then the rubber heads 12 on both sides will contact the workpiece. Under the action of the rubber heads 12 on both sides moving in the directions toward each other, the rubber heads 12 on both sides contacting the workpiece will be held by the workpiece and will no longer move toward each other. Then, under the action of the two mounting blocks 10 continuing to move in the directions toward each other, the rubber heads 12 in contact with the workpiece will push the oil in the two oil chambers 101 in the directions away from each other through the sliding rod 11, so that the oil in the oil chamber 101 enters the butt joint 132 through the second connecting pipe 134, and the oil in the butt joint 132 enters the housing 131 through the through hole 202 and the first connecting pipe 133, and then the oil in the two housings 131 will continue to increase, so that the oil will push the two piston plates 135 toward each other. The rubber heads 12 and the slide bars 11 on both sides that are not in contact with the workpiece will continue to move toward each other under the action of the mounting block 10 until all the rubber heads 12 are in contact with the workpiece. Then the rotation of the bidirectional screw rod 7 is stopped, and the two ball valves 201 are driven to rotate 90 degrees in the opposite direction through the two rotating rods 203, so that the through hole 202 is no longer connected with the first connecting pipe 133, so that the oil in the oil chamber 101 cannot circulate, so that the slide bars 11 on both sides are fixed in the current position. At this time, the rubber heads 12 on both sides will fit the workpiece and firmly clamp the workpiece. At this time, the staff can release the workpiece, and then start the servo motor 192. The output shaft of the servo motor 192 drives the driving gear 193 to rotate.Under the action of the engagement of the driving gear 193 and the ring gear 194, the driving gear 193 rotates and drives the swivel 9, the mounting block 10, the plug cover 102, the slide rod 11, the rubber head 12 and the workpiece to rotate through the ring gear 194. When the workpiece rotates to a suitable angle, the servo motor 192 is turned off, and then the staff starts the rodless cylinder 2. The sliding part of the rodless cylinder 2 drives the fixed rod 4, the rotating seat 5, the guide rod 6, the bidirectional screw 7, the first sliding frame 8, the swivel 9, the mounting block 10, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19, the limiting assembly 20 and the workpiece to move forward through the connecting seat 3. When the connecting seat 3 moves forward to the limit, the rodless cylinder 2 The sliding part of the cylinder 2 drives the fixed rod 4, the rotating seat 5, the guide rod 6, the bidirectional screw 7, the first sliding frame 8, the swivel 9, the mounting block 10, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19, the limiting assembly 20 and the workpiece to move backward through the connecting seat 3, so that the rodless cylinder 2 can drive the workpiece to move back and forth. When the workpiece moves to a suitable position, the rodless cylinder 2 is closed. The workpiece can be moved to a suitable position through the above operation, and the workpiece can be rotated to a suitable angle by rotating the workpiece, which is convenient for the staff to use mechanical equipment to process the workpiece later. When the workpiece is processed, the staff holds the workpiece and then rotates it in the opposite direction. The bidirectional screw rod 7 is driven by the two first sliding frames 8 to respectively drive the swivel 9, the mounting block 10, the oil chamber 101, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19 and the limiting assembly 20 on the two first sliding frames 8 to move away from each other. Then, when the two mounting blocks 10 are reset in the direction away from each other, the bidirectional threaded rod 222 is stopped from rotating in the opposite direction. At this time, the rubber heads 12 on both sides are no longer in contact with the workpiece. The staff removes the workpiece, and then drives the two ball valves 201 to rotate 90 degrees through the two rotating rods 203, so that the two through holes 202 are connected to the two first connecting pipes 133 respectively, so that the elastic member 136 The two piston plates 135 are reset and driven to move in opposite directions to reset. The two piston plates 135 then push the oil into the butt joint pipe 132 through the first connecting pipe 133 and the through hole 202. The oil in the butt joint pipe 132 then enters the oil chamber 101 through the second connecting pipe 134. Then the oil in the two oil chambers 101 will push the slide bars 11 on both sides to reset in opposite directions respectively. The slide bars 11 on both sides then drive the rubber heads 12 thereon to move in opposite directions to reset respectively. Finally, after the rubber heads 12 on both sides are moved in opposite directions to reset, the staff can drive the two ball valves 201 to rotate 90 degrees in the opposite direction respectively through the two rotating rods 203. In this way, the workpiece can be removed from the fixture through the above operation.

[0038] Example 2: Based on Example 1, please check Figure 1 and Figure 6, also includes a switch assembly 21, the switch assembly 21 includes a torsion spring 211, a connecting block 212, a second sliding frame 213 and a top block 214, the torsion spring 211 is connected between the two rotating rods 203 and the adjacent shell 131, the two torsion springs 211 are respectively sleeved on the two rotating rods 203, the rear sides of the two rotating rods 203 are connected with the connecting block 212 by welding, the rear sides of the two first sliding frames 8 are slidably connected with the second sliding frame 213, the second sliding frame 213 is made of iron material, which is convenient for the second sliding frame 213 to be magnetically attracted to the magnetic material, and there is a large friction between the two second sliding frames 213 and the adjacent first sliding frames 8, and the two second sliding frames 213 are connected with the top block 214 on the side away from each other by welding, and the two top blocks 214 are respectively in contact with the adjacent connecting block 212.

[0039] When it is necessary to connect the through hole 202 with the first connecting pipe 133, the staff pushes the two top blocks 214 upwards through the second sliding frame 213, and the two top blocks 214 push the adjacent connecting blocks 212 upwards respectively, and the two connecting blocks 212 respectively drive the rotating rods 203 thereon to rotate, and the torsion spring 211 is deformed, and the two rotating rods 203 respectively drive the adjacent ball valves 201 to rotate together. When the connecting block 212 drives the rotating rod 203 to rotate 90 degrees, the top block 214 moves upward and can no longer push the connecting block 212, and the through hole 202 is connected to the first connecting pipe 133, so as to achieve the above The operation can make the ball valve 201 rotate accurately by 90 degrees, which can avoid the accident that the through hole 202 cannot be accurately aligned with the first connecting pipe 133 due to hand shaking when the staff rotates the ball valve 201. When it is necessary to disconnect the through hole 202 from the first connecting pipe 133, the two top blocks 214 are pulled downward and reset by the second sliding frame 213, and the two top blocks 214 no longer push the adjacent connecting blocks 212 respectively, so that the torsion spring 211 is reset and the two connecting blocks 212 and the ball valve 201 are driven to rotate 90 degrees in the opposite direction through the two rotating rods 203, and then the through hole 202 is no longer connected to the first connecting pipe 133.

The block 10, the oil chamber 101, the plug cover 102, the slide bar 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19 and the limiting assembly 20 move in opposite directions, so that the rubber heads 12 on both sides will clamp the workpiece, and then the left conical cylinder 223 is released, the volute spring 2291 is reset and drives the left conical cylinder 223 to rotate in the opposite direction through the connecting rod 2292, and the left conical cylinder 223 moves to the left and resets after the reverse rotation, and the left conical cylinder 223 moves to the left and drives the first rack 226 to move to the left, and the first rack 226 moves to the left and drives the second rack 227 to move to the right through the transmission gear 229, and the second rack 227 drives the right conical cylinder 223 to move to the right and reset, so that the two conical cylinders 2 23 no longer pushes the adjacent magnetic frame 221, the reset spring 225 resets and drives the two magnetic frames 221 to move downward and reset, and under the action of the mutual magnetic attraction between the magnetic frame 221 and the second sliding frame 213, the two magnetic frames 221 then drive the two top blocks 214 to move downward through the second sliding frame 213, and the two top blocks 214 no longer push the adjacent connecting blocks 212, so that the torsion spring 211 resets and drives the two connecting blocks 212 and the two ball valves 201 to rotate in the opposite direction respectively through the two rotating rods 203. When the workpiece needs to be removed from the fixture, the workpiece is supported and the left conical cylinder 223 is rotated in the opposite direction. The left conical cylinder 223 drives the connecting rod 2292 and the volute spring 2291 to rotate in the opposite direction through the threaded rod 222.The threaded rod 222 then drives the bidirectional threaded rod 222 to rotate in the opposite direction, and the bidirectional screw rod 7 drives the swivel 9, the mounting block 10, the oil chamber 101, the plug cover 102, the slide rod 11, the rubber head 12, the hydraulic assembly 13, the rotating assembly 19 and the limiting assembly 20 on the two first slide frames 8 to move away from each other through the two first slide frames 8, and then the rubber heads 12 on both sides no longer clamp the workpiece, and the workpiece can be moved away at this time.

[0043] When the workpiece needs to be clamped, the workpiece can be placed on the support plate 232. In this way, the workpiece can be located between the rubber heads 12 on both sides without the staff having to continuously hold the workpiece, which brings convenience to the staff. When the two swivels 9 move in opposite directions, the ordinary spring 233 is compressed, and under the action of the ordinary spring 233, the ordinary spring 233 can keep the support plate 232 in the current position. When the two swivels 9 move away from each other, the ordinary spring 233 will reset. Example 3

[0044] Based on Example 4, please check Figure 7 , Fig.12 and Fig.13 , also includes a clamping assembly 24, the clamping assembly 24 includes a pressure rod 241, a diamond rod 242, a sliding plate 243, a compression spring 244 and a hemispherical block 245, the lower parts of the two first sliding frames 8 close to each other are connected with a pressure rod 241 by welding, the two pressure rods 241 are symmetrical, the top of the fixed rod 4 is connected with a diamond rod 242 by welding, the diamond rod 242 is slidably connected with a sliding plate 243, a compression spring 244 is connected between the sliding plate 243 and the diamond rod 242, the compression spring 244 is sleeved on the diamond rod 242, the bottom of the sliding plate 243 is evenly spaced with adaptive slots 246, the top of the rotating seat 5 is evenly spaced with hemispherical blocks 245 welded, and the hemispherical blocks 245 are in contact with the adaptive slots 246.

[0045] When the rotating seat 5 is rotated, the rotating seat 5 will drive the hemispherical block 245 thereon to rotate together, and then the hemispherical block 245 will push the sliding plate 243 upward after rotating, and the compression spring 244 will be compressed. Then, during the continuous rotation of the hemispherical block 245, the hemispherical block 245 will no longer push the sliding plate 243, so that the compression spring 244 will reset and drive the sliding plate 243 to move downward and reset. In this way, during the continuous rotation of the rotating seat 5, the sliding plate 243 will move up and down. When the rotating seat 5 is rotated to a suitable angle, the suitable position on the sliding plate 243 is Under the action of the contact between the slot 246 and the hemispherical block 245, the sliding plate 243 can limit the rotating seat 5 through the hemispherical block 245, and can prevent the rotating seat 5 from rotating at will. Thereafter, in the process of the two first sliding frames 8 moving in opposite directions, they will respectively drive the pressure rods 241 thereon to move in opposite directions, and the two pressure rods 241 will then press the sliding plate 243, so that the sliding plate 243 cannot move upward. At this time, the sliding plate 243 can prevent the rotating seat 5 from rotating after the workpiece is clamped on the fixture, thereby preventing the rotating seat 5 from changing the position of the workpiece after the rotating seat 5 rotates.
