Description

Technical Field

[0001] This utility model specifically relates to a high-temperature parts gripper, belonging to the field of clamping technology. Background Technology

[0002] During the machining of castings, high-temperature castings need to be handled and moved using specially designed fixtures.

[0003] However, the triangular grippers currently on the market still have some problems in the process of clamping high-temperature forgings. For example, the grippers are not resistant to high temperatures. When the casting comes out of the mold, the temperature is above 600 degrees Celsius. Ordinary grippers have a shortened lifespan in high-temperature environments.

[0004] Application No. 202121414487X discloses a triangular gripper for processing high-temperature forgings with anti-slip properties. The gripper includes a connecting arm with three connecting blocks mounted on its bottom. A groove is formed at the bottom of the connecting arm near the top of the connecting blocks. Each of the three connecting blocks has a gripping claw at its bottom. Three cylinders are fixed to the side wall of the connecting arm near the groove. A piston rod is mounted on the output shaft of each cylinder. A slider is fixed to one end of the piston rod extending into the groove. The slider extends to the outside of the connecting arm and connects to the connecting block. This invention, through the cooperation of a clamping plate, a fixing post, a groove, and a spring, ensures that the spring is always in a charged state during clamping, thus clamping the forging more firmly and stably, effectively preventing the forging from slipping and falling. It also greatly reduces the hard impact when in contact with the forging, thereby avoiding deformation and damage to the forging and improving safety.

[0005] The proposed solution uses three cylinders to drive the gripper, which results in an overly complex structure, excessive piping, high cost, and inconvenient maintenance. Utility Model Content

[0011] The lower end of the connecting rod is rotatably connected to the upper end of the gripper body;

[0012] The cylinder body is mounted on the base plate, and the piston rod of the cylinder is connected to the bottom of the slide plate;

[0013] The lower end of the gripper body is provided with a high-temperature resistant gripper;

[0014] The top of the base plate is provided with a cover that encloses the cylinder and the connecting rod.

[0015] Furthermore, a heat insulation plate is provided on the lower surface of the base plate.

[0016] Preferably, the insulation board is made of polyurethane rock wool.

[0017] Furthermore, the gripper body has multiple heat dissipation holes.

[0018] Furthermore, a heat insulation sleeve is provided on the outer side of the cover.
