Abstract

The invention relates to a hydraulic chuck device for spraying a polyurethane thermal insulation pipe. The hydraulic chuck device comprises a first oil cylinder, a second oil cylinder, a piston, a horizontal pull block, a vertical pull block, an outer supporting clamping jaw, a strain gauge, an inner clamping clamping jaw, a sealing block, a first chuck body, a second chuck body, a third chuck body, a fourth chuck body, a first oil valve, a second oil valve and a central control module. The theoretical oil inlet amount of the first oil cylinder is calculated through the central control module, and the oiling speed is determined by the theoretical oil inlet amount of the first oil cylinder; and when the central control module starts the first oil valve to add oil to the first oil cylinder, the strain gauge detects the pressure borne by the strain gauge in real time, a flow detector records the oil injection amount of the first oil cylinder in real time, and the central control module adjusts the oil adding speed of the first oil cylinder according to the pressure borne by the strain gauge and the oil injection amount of the first oil cylinder. By intelligently adjusting the oiling speed of the oil cylinders, the situation that a to-be-sprayed pipeline is damaged due to the too high oiling speed and the too large supporting force of the outer supporting clamping jaw is prevented.

Description

technical field [0001] The invention relates to the technical field of workpiece fixing, in particular to a hydraulic chuck device for polyurethane insulation pipe spraying. Background technique [0002] The chuck is a device used to clamp the workpiece during machine tool processing. The chuck of the existing disc parts processing machine tool adopts a three-jaw or four-jaw mechanism, and the jaws are a rectangular parallelepiped. The hydraulic chuck uses a hydraulic device to drive the jaw The centripetal movement is used for clamping. When fixing the tubular workpiece to be sprayed, the jaws are supported on the inner surface of the workpiece, and one end surface of the workpiece is close to the chassis. However, in the existing external support fixing process, the clamp When the claw supports the inner surface of the workpiece, the surface of the chuck is worn out due to long-term use, which makes it difficult to control the force of the outer support when supporting the...
