Supporting and automatic adjusting device for check tools and control method of supporting and automatic adjusting device

Abstract

The invention discloses a supporting and automatic adjusting device for check tools and belongs to the technical field of clamps. The supporting and automatic adjusting device for check tools comprises a clamping mechanism and an adjusting mechanism connected with the clamping mechanism; the clamping mechanism comprises a fixing seat, a guide shaft and a clamp assembly, wherein the fixing seat isarranged at the top of a supporting frame, the guide shaft penetrates through the fixing seat, and the clamp assembly sleeves the guide shaft and extends out of the fixing seat; the clamp assembly comprises a change-over block, a supporting arm, a clamp, a transverse force arm and a vertical pressing rod, wherein the change-over block is in sleeved connection with the guide shaft, the supporting arm is detachably and rotationally connected with the change-over block, the clamp is connected with the supporting arm, the transverse force arm is connected with the clamp and can be transversely moved so as to be adjusted, the vertical pressing rod is arranged at an end portion of the transverse force arm and can ascend and descend so as to be adjusted, and the vertical pressing rod is corresponding to the guide shaft; the top of a transmission screw rod is in threaded connection with the guide shaft; and the input parameters of a stepping motor can be set, so that the movement speed, forward and reverse direction and movement time of the transmission screw rod can be adjusted. The supporting and automatic adjusting device for the check tools of the invention is suitable for detecting parts with different specifications and parameters and automatically adjusting and identifying deviation positions.

Description

technical field [0001] The invention belongs to the technical field of fixtures, and in particular relates to an automatic adjustment device for checking fixture support and a control method thereof. Background technique [0002] With the continuous development of the domestic automobile industry, industry competition is becoming increasingly fierce, and users have higher and higher requirements for the quality of automobiles. In order to maintain product competitiveness, automobile manufacturers are accelerating the pace of model updates and launching new models. At the same time, various automobile manufacturers are also In the continuous adoption of new technologies and new processes, it has also turned its attention to the development of measurement technology. The development of manufacturing technology is also inseparable from measurement technology, and the two complement each other and promote each other. The new measurement technology constantly reveals the deficie...

Problems solved by technology

As the basic components of measurement technology, inspection fixtures and fixtures play an increasingly obvious role in the production site. The traditional form of special inspection fixtures and fixtures for a single car model has gradually failed to meet the requirements. Higher requirements are put forward for economy and quick response ability, so meeting multi-function, flexibility, high efficiency and low cost directly determines customer satisfaction

[0003] In the fixing and simulation test of sheet metal welding points during welding assembly and positioning inspection of automobile body-in-white, when using three-coordinate measuring equipment to measure workpieces on inspection tools or fixtures, it is often necessary to measure workpieces or measurement points. Local high-precision adjustment or sliding, in order to ensure that the fine-tuning range can be controlled within the accuracy of ± 0.1mm, adjust the overall inspection tool and fixture or disassemble and adjust the measuring point; The process is easy to damage the main parts of the inspection tool, which affects the accuracy of later adjustment; automatic adjustment cannot be realized, and multi-point synchronization or sequence adjustment cannot be realized at the same time. The adjustment of the overall mechanism is not easy to operate and the accuracy is not high.
