Description

Technical Field

[0001] The utility model relates to the technical field of bearing measuring tools, in particular to a bearing positioning groove inspection tool with convenient operation. Background Art

[0002] As is well known, when a bearing works, it needs to be assembled into a corresponding bearing seat. The outer ring of the bearing is fixed to the bearing seat as a whole to achieve circumferential and axial positioning. When performing circumferential positioning, a common method is to provide a pair of symmetrically arranged positioning grooves on the outer ring of the bearing, and the cooperation between the positioning grooves and the corresponding structures in the bearing seat is used to prevent relative rotational displacement between the outer ring of the bearing and the bearing seat. Therefore, the machining quality of the positioning grooves directly affects the assembly quality with the bearing seat, and it is very necessary to inspect and measure the bearing positioning grooves.

[0003] Among them, the measurement items include groove width, groove bottom inclination, and symmetry of two positioning grooves on the same bearing, which undoubtedly increases the measurement difficulty, makes the detection work very troublesome, and has the problems of time-consuming, laborious, and low measurement efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bearing positioning groove inspection tool with reasonable structure, reliable use, convenient operation, high measurement accuracy, and significantly improved measurement efficiency to solve the above problems.

[0005] The technical solution of the utility model is as follows:

The technical key points are: the inspection tool body is a cross-shaped inspection body, and the cross-shaped inspection body is composed of a pair of symmetrically arranged positioning and supporting parts and another pair of symmetrically arranged measurement and execution parts. The positioning and supporting parts are composed of a first horizontal supporting part and an arc-shaped limiting part arranged at the end of the first horizontal supporting part and used for attaching to the outer peripheral surface of the outer ring of the bearing to be measured. The measurement and execution parts are composed of a second horizontal supporting part and a clamping part arranged at the end of the second horizontal supporting part and used for clamping into the positioning groove of the outer ring of the bearing to be measured. A clamping block is embedded on the lower surface of the clamping part, and the lower surface of the clamping block is an inclined surface used for attaching to the bottom of the positioning groove. The width of the clamping block is equal to the groove width of the positioning groove.

If the two clamping blocks of the measuring execution part smoothly enter the corresponding positioning grooves and are attached to the groove bottom, it means that the measurement result is qualified. If the two clamping blocks cannot smoothly enter the positioning grooves, it means that the measurement result is unqualified. Observe the measurement state to clearly determine whether the size of the positioning groove meets the requirements. The measurement accuracy is high. At the same time, the operation is convenient, the measurement speed is fast, and the measurement efficiency is significantly improved. Description of the Drawings

[0018] Describe the present utility model in detail according to the accompanying drawings of the specification.

[0019] As Figures 1 to 3 shown, this bearing positioning groove gauge that is convenient to operate includes a gauge body, and the gauge body is a cross-shaped gauge body 2.

[0020] Among them, the cross-shaped inspection body 2 is composed of a pair of symmetrically arranged positioning and supporting parts and another pair of symmetrically arranged measurement and execution parts. The positioning and supporting parts are composed of a first horizontal supporting part 201 and an arc-shaped limiting part 4 provided at the end of the first horizontal supporting part 201 and used for attaching to the outer peripheral surface of the bearing outer ring to be measured. The measurement and execution parts are composed of a second horizontal supporting part 202 and a clamping part 204 provided at the end of the second horizontal supporting part 202 and used for clamping into the positioning groove of the bearing outer ring to be measured.

[0021] A clamping block 3 is embedded in the lower surface of the clamping part 204. The lower surface of the clamping block 3 is an inclined surface for attaching to the bottom of the positioning groove, and the width of the clamping block 3 is equal to the groove width of the positioning groove. In this embodiment, the inclination of the inclined surface of the clamping block 3 is 45°. Clamping edges are provided on both sides of the upper end of the clamping block 3, and clamping grooves are provided on the upper surface of the clamping part 204 for cooperating with the clamping edges 3 to facilitate assembly. The split structure of the clamping block 3 and the clamping part facilitates the replacement of the worn clamping block and avoids waste of resources.

[0022] In this embodiment, a rubber handle 1 is provided at the center of the upper surface of the cross-shaped inspection body 2. A central hole 205 is provided on the upper surface of the cross-shaped inspection body 2. The tip of the positioning screw 5 passes through the central hole 205 and is threadedly connected to the bottom of the rubber handle 1.

[0023] The lower surfaces of the first horizontal supporting part 201 of the positioning and supporting parts and the second horizontal supporting part 202 of the measurement and execution parts are located in the same horizontal plane. During use, the lower surfaces of the first horizontal supporting part 201 and the second horizontal supporting part 202 are in contact with the upper end surface of the bearing to be detected. A weight-reducing hole 203 is provided on the first horizontal supporting part 201 of the positioning and supporting parts.

[0024] Working principle:

[0025] Hold the rubber handle 1 and buckle it on the upper end surface of the bearing to be detected. Specifically, first make the two clamping blocks 3 correspond to the positioning grooves on the bearing outer ring, and then press down the cross-shaped inspection body 2 so that the inner side wall of the arc-shaped limiting part 4 of the positioning and supporting parts is attached to the outer peripheral surface of the bearing outer ring to be detected. Continue to press down. If the lower surfaces of the first horizontal supporting part 201 and the second horizontal supporting part 202 are attached to the upper end surface of the bearing to be detected, and the two clamping blocks 3 of the measurement and execution parts smoothly enter the corresponding positioning grooves and are attached to the groove bottom, it indicates that the size of the measured bearing positioning groove (the groove bottom has an inclination of 45°) is qualified. At the same time, the two positioning grooves on the bearing are symmetric with each other.

[0026] If the two clamping blocks 3 cannot smoothly enter the positioning grooves, it indicates that the measurement result is unqualified. Observe the measurement state to clearly determine whether the size of the positioning groove meets the requirements and whether it is symmetric.

[0027] The above has described the embodiments of the present utility model in detail, but the above content is only the preferred embodiments of the present utility model and cannot be considered as defining the scope of implementation of the present utility model. All equal changes and improvements made within the scope of the creation of the present utility model shall still fall within the scope covered by this patent.
