Precision detection equipment for overturn chuck with automatic adsorption function

Abstract

The invention relates to precision detection equipment for an overturn chuck with an automatic adsorption function, which comprises an overturn chuck, a detection device, a gauge stand bracket and a reading dial gauge for measuring the deviation, and is characterized in that the overturn chuck comprises an upper clamping device and a lower clamping device which are used for clamping the detectiondevice from the upper side and the lower side respectively, the gauge stand bracket comprises a bracket shell, a support rod, an electromagnet and a control switch used for controlling on-off of the electromagnet, the electromagnet is arranged in the bracket shell and is connected with the control switch arranged at the surface of the bracket shell, and two ends of the support rod are connected with the bracket shell and the reading dial gauge used for measuring the deviation respectively. Compared with the prior art, the gauge stand bracket adopts electromagnet type adsorption, thereby beingconvenient for disassembly. Meanwhile, the moment when a magnetic force is generated is controllable, so that the overturn chuck is automatically adsorbed at the instant when the electromagnet is powered on, and great impulsion between the gauge stand bracket and the detection device due to traditional sudden increase in magnetic force is avoided.

Description

technical field [0001] The invention relates to a detection device for a flip chuck, in particular to a detection device for the precision of a flip chuck with an automatic adsorption function. Background technique [0002] CNC threading machine is a special double-axis double-chuck CNC machine tool, which is specially used to process internal thread pipe couplings for oil well pipes and oil casings according to API standards. Due to the high accuracy of the internal thread of the pipe coupling, there are also high requirements for the accuracy of the machine tool. However, the machine tool has a high frequency of use, a large cutting load and poor working conditions. It directly leads to a sharp decline in the accuracy and functions of the turning mechanism of the turning chuck, which is reflected in the continuous decline in the pass rate of the workpiece and the sharp increase in the loss of the used cemented carbide tools. The decline in the qualified rate is mainly man...

Problems solved by technology

However, the detection device is fixed on the end cover or the fixed end with the iron-absorbing table bracket, which has the problem of difficulty in disassembly. Moreover, because of the lack of horizontal calibration function, the detection device needs to be rotated 180 degrees horizontally to measure the deviation on both sides. Measure the degree of inclination
