Problems solved by technology

[0003] In the prior art, after a period of continuous spraying operation, the heat energy generated during the spraying operation is conducted to the chuck. Due to the different distances from the heat conduction to different parts of the chuck, the temperature rise and expansion of different parts of the chuck are different, making the chuck The movable jaws of the disk are difficult to move or even unable to move (that is, stuck phenomenon), the spraying operation needs to be stopped, and after the chuck cools down, the movable jaws can be moved again to clamp and position the sprayed workpiece

Abstract

The invention relates to the technical field of surface engineering, and particularly discloses a high-temperature-resistant dustproof chuck device. The device comprises a chuck body, clamping jaws installed on the chuck body, a dustproof cover arranged on the chuck body in a sleeving mode and coaxial with the chuck body, and shielding covers installed on the outer side of the dustproof cover and communicating with the interior of the dustproof cover; the dustproof cover is provided with a groove used for installing the chuck body, and a gap exists between the bottom of the groove and the upper surface of the chuck body; and the shielding covers and the clamping jaws are arranged in a one-to-one correspondence mode. According to the device, dust can be prevented from entering gaps between the clamping jaws and the chuck body, and the device is resistant to high temperature.

Description

technical field [0001] The invention relates to the technical field of surface engineering, and more particularly, to a high temperature resistant dustproof chuck device. Background technique [0002] Plasma spraying, flame spraying, supersonic spraying and other high temperature spraying and cold spraying are a kind of important surface modification methods of materials. The chuck is a mechanical device used to clamp the workpiece during the spraying process. It uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the sprayed workpiece. [0003] In the prior art, after the continuous spraying operation for a period of time, the heat energy generated during the spraying operation is conducted to the chuck. Due to the different distances from the heat conduction to different parts of the chuck, different parts of the chuck have different temperature rises and different expansions. The movable jaws of the disc are difficult t...
