Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a three-jaw cylinder capable of clamping long parts, including a cylinder body 1 and a slidable jaw 2 mounted on the top of the cylinder body 1. The jaw 2 has three jaws equidistantly arranged around its axis. The jaw 2 is detachably mounted with an adjustable clamping part 3 and a fixing part 4 for pressing and fixing the clamping part 3. The clamping part 3 can clamp workpieces of different lengths by adjusting its length. After the clamping part 3 is first installed on the jaw 2, it can be fixed and supported by the fixing part 4.

[0019] The clamping part 3 includes a clamping plate 15, an extension plate 16 is provided on the clamping plate 15, an arc plate 17 is fixedly connected to one side of the extension plate 16, a second bolt 19 is threadedly connected to the clamping plate 15, and a third fixing hole 18 is provided on the extension plate 16. The second bolt 19 can be threadedly connected to the third fixing hole 18. The extension plate 16 can slide up and down in the clamping plate 15 to adjust its length. After adjustment, it can be fixed by tightening the second bolt 19 into the corresponding third fixing hole 18. After the extension plate 16 is completely pulled out, it is rotated 180° to rotate the arc plate 17 to the side closer to the cylinder body 1, so that the clamping part 3 can stably clamp the cylindrical part.

[0020] The clamping plate 15 is fixedly connected to one side with a strip 13. The strip 13 has an insertion hole 14 inside. The top of the gripper 2 has a slot 5 for the strip 13 to be inserted. The clamping plate 15 can be fixed to the gripper 2 by inserting the strip 13 into the slot 5.

[0021] The fixing part 4 includes a reinforcing seat 9, a fixing block 11 is fixedly connected to the bottom of the reinforcing seat 9, and a plug rod 12 is fixedly connected to the bottom of the fixing block 11. The plug rod 12 can cooperate with the plug hole 14. The top of the gripper 2 is provided with a fixing groove 6, and the fixing block 11 can cooperate with the fixing groove 6. After the clamping plate 15 is installed on the gripper 2, the fixing block 11 will be inserted into the fixing groove 6. The clamping plate 15 can be fixed by inserting the plug rod 12 into the plug hole 14.

[0022] The reinforcing seat 9 has a second fixing hole 10 inside, and a first bolt 8 is threadedly connected inside the second fixing hole 10. The top of the gripper 2 has a first fixing hole 7, and the first bolt 8 can be threadedly connected to the first fixing hole 7. After the reinforcing seat 9 is installed on the gripper 2, the reinforcing seat 9 can be fixed by tightening the first bolt 8.

[0023] Specifically, when the cylinder 1 is working, it can drive the three grippers 2 of the clamping part to move closer to or further away from the axis of the cylinder 1 to clamp or release the workpiece. When the workpiece is too long, the insert 13 can be inserted into the slot 5, and then the reinforcing seat 9 can be installed on the gripper 2. The fixing block 11 can be inserted into the fixing slot 6, so that the insert rod 12 is inserted into the insertion hole 14 to fix the insert 13. Then, the first bolt 8 needs to be tightened to fix it in the first fixing hole 7 to fix the reinforcing seat 9. After loosening the second bolt 19, the length can be adjusted by pulling out the extension plate 16. After the adjustment is completed, the second bolt 19 is tightened again to enter the corresponding third fixing hole 18 to fix the position of the extension plate 16. If it is necessary to clamp a long cylindrical part, the extension plate 16 can be pulled out and then rotated 180° so that the arc plate 17 faces the direction closer to the cylinder 1. The arc plate 17 can fit with the cylindrical part.
