DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 , Figure 4 , Figure 5As shown, this embodiment discloses a clamping device for automatic assembly of pipe joints, including a base 1, a clamp 2, and a rotating member 3. The base 1 is fixedly mounted on the upper end surface of a first circular plate 81 (the first circular plate 81 can rotate), the base 1 is provided with a seat groove 11, two rotating members 3 are respectively rotatably mounted on the two side surfaces of the seat groove 11 of the base 1, and the rotation centers of the two rotating members 3 are consistent with the axial direction of the first circular plate 81. The clamp 2 is mounted on the base 1 through the rotating member 3, and the clamp 2 can rotate in the seat groove 11. The driving component 6 is mounted on the second circular plate 82 (the second circular plate 82 is fixed), and the driving component 6 includes a feeding cylinder 61 and a rotating cylinder 62. The feeding cylinder 61 is fixedly mounted on the second circular plate 82, and the feeding cylinder 61 drives the rotating cylinder 62 to approach or move away from the clamping component. The rotating cylinder 62 is provided with a fixed position capable of rotating. The positioning block 63, the rotation axis of the positioning block 63 is consistent with the axial direction of the first circular plate 81, the rotating member 3 is provided with a positioning slot 31 corresponding to the positioning block 63, the positioning block 63 and the positioning slot 31 are plugged into each other to form a limit in the rotation direction. When the fixture 2 needs to be rotated, the feed cylinder 61 is started to push out the rotating cylinder 62, so that the positioning block 63 is inserted into the corresponding positioning slot 31, the rotation of the rotating cylinder 62 can drive the fixture 2 to rotate, and then the pipe joint 101 clamped in the fixture 2 can be rotated to adjust the pipe end to be installed, and all the pipe ends of the pipe joint 101 can be installed with the required components in the same installation position. After the installation is completed, the feed cylinder 61 is retracted to disengage the positioning block 63 from the positioning slot 31, and the first circular plate 81 can be rotated to move the clamping assembly to the next working position.

[0022] More preferably, the base 1 is equipped with a spring latch 4, which can be inserted into a corresponding recessed hole of the rotating member 3 to position the rotating member 3 after the rotating member 3 rotates. During rotation, the spring latch 4 can be disengaged from the recessed hole due to the force of rotation.

[0023] like Figure 4 As shown, the present embodiment also includes a positioning device 7, and the positioning device 7 is distributed along the rotation direction of the first circular plate 81. The positioning device 7 includes a first cylinder 71 and an insertion rod 72. The first cylinder 71 can drive the insertion rod 72 to extend and retract up and down, and the insertion rod 72 can be inserted into the positioning slot 31 of the rotating part 3 away from the center side of the first circular plate 81. The positioning slot 31 is formed in a cross shape, and the positioning slot 31 passes through the circumferential side wall of the rotating part 3. When the pipe joint 101 on the clamp 2 is assembled, the first cylinder 71 drives the insertion rod 72 to rise and insert it into the positioning slot 31 to lock the rotation direction of the rotating part 3, further ensuring that the clamp 2 will not rotate and deviate when the pipe joint 101 is assembled, and the assembly process is more stable.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, the clamp 2 includes a clamp seat 21, a first clamp block 22, a second clamp block 23, a rear cover 24, a first transmission rod 25, a second transmission rod 26, a gear 27, and a second spring 29. The clamp seat 21 is provided with a guide groove 211, and the first clamp block 22 and the second clamp block 23 can slide along the guide groove 211. The rear cover 24 is installed on the clamp seat 21. The first transmission rod 25, the second transmission rod 26, the gear 27, and the second spring 29 are installed between the rear cover 24 and the clamp seat 21. The gear 27 is rotatably connected to the inside of the rear cover 24. The first transmission rod 25, the second transmission rod 26, the gear 27, and the second spring 29 are installed between the rear cover 24 and the clamp seat 21. 26 are respectively located at the upper and lower sides of the gear 27, and the first transmission rod 25 and the second transmission rod 26 are arranged in parallel.

One end of the first transmission rod 25 is fitted with a first spring 28, and the first spring 28 abuts against the first rack 251 and the inner wall of the rear cover 24. The second transmission rod 26 has the same structure as the first transmission rod 25 and is located at the first transmission rod 25. The first spring 28 and the second spring 29 of the second transmission rod 25 and the second transmission rod 26 provide the first clamping block 22 and the second clamping block 23 with a force to clamp the pipe joint 101 close to each other. When the first transmission rod 25 moves, the rack of the first transmission rod 25 drives the gear 27 to rotate and then drives the second transmission rod 26 to move. The first transmission rod 25 is connected to the first clamping block 22, and the second transmission rod 26 is connected to the second clamping block 23. When the first transmission rod 25 moves, it can drive the second transmission rod 26 to move in the opposite direction, so that the first clamping block 22 and the second clamping block 23 can move relative to each other. The first clamping block 22 and the second clamping block 23 are moved closer to or farther away from each other, and the pipe joint 101 can be clamped between them. As shown in the figure, the opening cylinder 5 is provided with a push rod 51, and the push rod 51 can be extended and retracted toward the first transmission rod 25. When the opening cylinder 5 is started, the push rod 51 can be extended to press against the first transmission rod 25 and push the first transmission rod 25 to move away from the opening cylinder 5, and at the same time, the second transmission rod 26 moves toward the direction close to the opening cylinder 5. At this time, the first clamping block 22 and the second clamping block 23 are moved away from each other, and the pipe joint 101 can be put into or taken out of the clamp 2.
