Problems solved by technology

[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.

Embodiment 1

[0021] Embodiment 1: as figure 1 , figure 2 In the shown embodiment, a device for detecting the outer diameter of a three-ball needle roller bearing includes a base plate seat 1, a feeding cylinder, a slide pad 2, and a positioning part. The feeding cylinder is provided with a feeding push plate 3. The skateboard spacer is fixed on the upper surface of the floor seat, and two white steel bars 4 are arranged on the skateboard spacer, and a bearing sliding groove is formed between the two white steel bars on the top of the skateboard spacer , a white steel retaining bar is provided with positioning and extends into the slot hole 5, and the positioning part includes a moving positioning block 6, a positioning cylinder 7 connected with the moving positioning block, and one end of the moving positioning block is provided with a V-shaped The positioning groove, the V-shaped positioning groove extends into the slot hole towards the positioning, the contact measurement block is prov...

Embodiment 2

[0027] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as image 3 As shown, the moving positioning block is provided with a roundness detection probe 17, the roundness detection probe is in the V-shaped positioning groove, and the roundness detection probe extends into the slot towards the positioning, The roundness detection probe is a distance sensor or a pressure sensor.

[0028] After the bearing positioning is completed, before, after or even at the same time as the outer diameter detection, the roundness detection probe can also be used to detect another point on the outer ring of the three-ball needle roller bearing. When positioning the bearing, the V-shaped positioning groove and The bearing outer ring has two contact lines. When the final test result is within the qualified value range, at least three dimensions on the outer ring of the bearing are qualified, one is the diameter of th...

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...
