Three-ball-pin needle bearing outer diameter detecting device

Abstract

The present invention discloses a three-ball-pin needle bearing outer diameter detecting device and aims to provide a detection device with a continuous detection process, effective and accurate detection positioning, a convenient detection process, and the high accuracy of a detection result. The device comprises a bottom plate base, a sliding plate seat, a sliding plate bearer, and a positioning part. A feeding cylinder is provided with a feeding push plate. The sliding plate bearer is fixed at the upper surface of the bottom plate seat and is provided with two white steel baffle bars. One white steel baffle bar is provided with a positioning extending slot. The positioning part comprises a mobile positioning block and a positioning cylinder. The mobile positioning block is provided with a contact measurement block. A probe fixing block is arranged under the bottom plate base and is provided with an outer diameter detecting probe. The three-ball-pin needle bearing outer diameter detecting device has the advantages that the positioning of a detected bearing can be effectively carried out, the detection is carried out through an auxiliary structure, the bearing is not measured directly, the observation is facilitated, the detection precision and convenience are improved, a kick structure is arranged, a defective bearing can be separated, and the follow-up collection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of bearing size detection, and in particular relates to a detection device for the outer diameter of a three-ball pin roller bearing. Background technique [0002] Three-ball needle roller bearings are mainly used in the field of three-ball universal joints, which require high assembly dimensional accuracy. In actual production, due to factors such as technology and processing accuracy, some three-ball needle roller bearings will inevitably appear. The outer diameter of the outer ring is out of tolerance, which will affect the quality of assembly and after assembly, and affect the use of parts. Therefore, it is necessary to test the outer diameter of the bearing before assembly. At present, for the outer diameter detection of the three-ball needle roller bearing, the comparison tool is mainly used to measure and observe the results, and because the reasonable value range of the outer diameter of the three-ba...

[0002] Three-ball needle roller bearings are mainly used in the field of three-ball universal joints, which require high assembly dimensional accuracy. In actual production, due to factors such as technology and processing accuracy, some three-ball needle roller bearings will inevitably appear. The outer diameter of the outer ring is out of tolerance, which will affect the quality of assembly and after assembly, and affect the use of parts, so it is necessary to test the outer diameter of the bearing before assembly

At present, for the outer diameter detection of the three-ball needle roller bearing, the comparison tool is mainly used to measure and observe the results, and because the reasonable value range of the outer diameter of the three-ball needle roller bearing outer ring itself is small, it has a great impact on the detection accuracy. The requirements are also very high, and the current detection device for the outer diameter of the outer ring of the three-ball needle bearing is still lacking in the detection continuity, detection efficiency, and accuracy of the detection results.
