[0019] The present invention will be further described below with reference to the accompanying drawings. A pneumatic clamp pliers for assembling universal joints includes a cylinder 1, which includes an output shaft 11 and a mounting bracket 2 mounted on the cylinder; a connector 3 connected to the output shaft; and two grippers 4 rotatably mounted on the mounting bracket and connected to the connector 41 via a connecting rod 41. The two grippers include a first position where they are close to each other to clamp the clamp, and a second position where they are far apart to allow the clamp to move in and out. In use, the protrusion of the clamp is placed between the two grippers, the cylinder is activated, and the jaws 40 of the grippers move close to clamp the two side walls of the protrusion to achieve assembly, greatly reducing worker fatigue and increasing assembly efficiency.

[0020] In this embodiment, as shown in the figure, the mounting frame includes an upper plate 21 and a lower plate 22, and the gripper is mounted between the upper plate and the lower plate. The space between the upper plate and the lower plate is used for the rotation of the connecting rod and the gripper.

[0021] In this embodiment, as shown in the figure, the mounting bracket further includes a connecting seat 23, which is connected to the cylinder. The connecting seat has a boss 24 for mounting the upper plate. The connecting seat has an axially threaded hole 230, and the mounting hole has threads. Threads are also provided on the outer wall of the cylinder to achieve quick assembly and disassembly. The boss and the upper plate are assembled using fasteners.

[0022] In this embodiment, as shown in the figure, the connector head is provided with a mounting hole 31, which is threadedly connected to the output shaft. The inner wall of the mounting hole is threaded, and the output shaft is also threaded for installation. If necessary, a nut can be added for fixation.

[0023] In this embodiment, as shown in the figure, the connector head is provided with a mounting plate 32, and the mounting plate is provided with a first rotating shaft. The connecting rod is rotatably connected to the first rotating shaft. There are two mounting plates, one at the top and one at the bottom, with the first rotating shaft placed between the two plates. Then, a hinge hole that mates with the first rotating shaft is provided on the connecting rod.

[0024] In this embodiment, as shown in the figure, the mounting bracket is provided with a second rotating shaft 25, and the gripper is provided with a shaft hole 42 that is hinged to the second rotating shaft.

[0025] In this embodiment, as shown in the figure, a guide pin 26 is provided between the upper plate and the lower plate, and an arc-shaped groove 44 is provided on the gripper to cooperate with the guide pin, thus playing a certain guiding role.

[0026] In this embodiment, as shown in the figure, the upper plate is provided with a through groove 211, and the connector is disposed opposite to the through groove.
