Numerical-control detection device for bearing-keeping-device rivet separating force

Abstract

The invention relates to a numerical-control detection device for bearing-keeping-device rivet separating force. The numerical-control detection device comprises a base, a lifting mechanism, an upper mold pressing piece, a lower mold pressing piece, a rotating mechanism and a torque detection mechanism. The lifting mechanism is vertically installed on the base, the upper mold pressing piece and the lower mold pressing piece are sequentially installed on the lifting mechanism, a lower pressing mold is arranged on the lower mold pressing piece, and the lifting mechanism drives the lower pressing mold to vertically move; the torque detection mechanism comprises a torque measuring instrument and a measuring bar, a pressure measuring bar is installed at the tail end of the measuring bar, an upper pressing mold corresponding to the lower pressing mold is arranged on the lower surface of the upper mold pressing piece, and a plurality of positioning grooves for positioning the pressure measuring bar are formed in the upper pressing mold, and correspond to rivets on a detected keeping device placed on the lower pressing mold one by one. According to the numerical-control detection device, the pressure measuring bar on the torque detection mechanism is matched with the lifting mechanism, the moment separating force, in the static state, of a riveting part of the detected keeping device is detected, the lower pressing mold is driven by the rotating mechanism to rotate, and the detection accuracy and the detection efficiency are improved.

Description

Technical field [0001] The invention relates to the technical field of detection equipment, in particular to a numerical control detection equipment for the rivet detachment force of a wave-shaped bearing retainer. Background technique [0002] A few days ago, in order to ensure the quality of the bearing, it is necessary to measure its various technical parameters, and the inspection of the rivet release force on the bearing retainer is one of the important testing items of the finished bearing. It refers to the The riveting strength of the rivet is tested. In the prior art, most of the bearing holders are placed on a fixed seat and the holder is fixed on the surface of the fixed seat by a positioning member. The rivets on the holder are detected one by one by a torque detection instrument. It is difficult to fix, the detection efficiency is low, and the detection bearing retainer has a single specification and high cost. [0003] Chinese utility model patent 201420462267.8 disc...

Problems solved by technology

[0005] The object of the present invention is to address the deficiencies of the prior art, and provide a numerically controlled detection device for the rivet breakaway force of a bearing retainer, which utilizes the pressure measuring rod on the torque detection mechanism to cooperate with the lifting mechanism to instantly measure the riveted part of the measured retainer under static conditions. The detachment force is detected, and the lower die is driven by the rotating mechanism to realize the step-by-step and continuous detection of the rivets on the measured retainer, which improves the detection accuracy and efficiency. It has a high degree of automation and strong versatility. In the existing technology, there are problems of slow detection and low precision in direct detection of retainer rivets by torque detection instruments
