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

Embodiment 1

[0035] The embodiments are described below with reference to the drawings. The embodiments shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configuration shown in the embodiments below are not limited to the invention described in the claims. Necessary for the solution.

[0036] Such as figure 1 As shown, a numerical control detection device for rivet disengagement force of a bearing holder includes a base 1, a lifting mechanism 2, an upper molded part 3, a lower molded part 4, a rotating mechanism 5, and a torque detection mechanism 9. The lifting mechanism 2 is installed vertically On the base 1, one ends of the upper molded part 3 and the lower molded part 4 are sequentially installed on the lifting mechanism 2, and the other end is connected by two symmetrical guide posts 6, such as figure 2 As shown, the lower mold pressing part 4 is provided with a lower mold 8 for positioning the tested holder 7....

Embodiment 2

[0046] Such as Picture 9 As shown, the components that are the same as or corresponding to those in the first embodiment use the reference numerals corresponding to those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment and figure 1 The difference in the first embodiment shown is that the pressure measuring rod 93 in this embodiment includes a vertical fixing part 931 sleeved on the end of the measuring rod 92 and at least one horizontal pressure measuring part 932. The parts 932 are fixed to the side wall of the vertical fixing part 931 by corresponding reinforcement parts 933. The number of the horizontal pressure measuring parts 932 on the pressure measuring rod 93 can be set according to the number of rivets on the holder 7 under test. , And cooperate with the numerical control programming to control the rotation angle of the rotating cylinder 51, so as to be suitable for measurin...

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...
