Description

A bearing height detection device under pressure

technical field

The utility model relates to the field of bearings, in particular to a bearing height detection device under pressure for a stamped outer ring thrust combined bearing.

Background technique

For the method of measuring the height of the stamped outer ring thrust combined bearing under pressure, the currently used method is to measure directly with a vernier caliper or to measure with a mechanically controlled electronic universal testing machine. The former has a large error in measurement because no pressure is applied to the bearing, and the latter Due to the bulky tooling and difficult measurement, there are large errors.

A gap is provided between the gland and the positioning sleeve, the top end of the spring abuts against the nut of the bolt, the bottom end of the spring abuts against the top surface of the gland, and the handle is fixed on the nut of the bolt.

In order to facilitate pressing the bearing, the bottom end of the gland is turned outward to form a flange.

In order to facilitate the disassembly and assembly of the handle, the handle is connected with the nut of the bolt through screw threads.

In order to facilitate the positioning of the bearing, a boss is provided on the upper surface of the base, and the positioning sleeve is arranged on the boss.

The beneficial effects of the utility model are: the bearing height detection device under pressure of the utility model is simple in structure, small in shape, easy to use, easy to operate, small in measurement error, improves detection efficiency, and saves detection cost at the same time.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural schematic diagram of the bearing height detection device under pressure of the present invention.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, a bearing height detection device under pressure includes a base 7, a gland 4, a bolt 1, a positioning sleeve 5, a spring 3 and a handle 2, the center of the base 7 is provided with a threaded hole, and the bolt 1 Threaded connection with the threaded hole of the base 7, the gland 4, the positioning sleeve 5, and the spring 3 are respectively sleeved outside the screw rod of the bolt 1, the bottom end of the positioning sleeve 5 abuts against the upper surface of the base 7, and the gland 4 sets are arranged outside the positioning sleeve 5, and there is a gap between the gland 4 and the positioning sleeve 5. The top end of the spring 3 abuts against the nut of the bolt 1, and the bottom end of the spring 3 abuts against the top surface of the gland 4. The handle 2 is fixed on the nut of the bolt 1.

In order to facilitate pressing the bearing, the bottom end of the gland 4 is turned outwards to form a flanging, which is an annular surface matching the end face of the stamped outer ring thrust combined bearing 6 .

In order to facilitate the assembly and disassembly of the handle 2, the handle 2 is connected to the nut of the bolt 1 through threads.

In order to facilitate bearing positioning, a boss is provided on the upper surface of the base 7, and the positioning sleeve 5 is arranged on the boss.

When measuring, put the stamped outer ring thrust combined bearing 6 between the base 7 and the gland 4, use the positioning sleeve 5 to position the stamped outer ring thrust combined bearing 6, and rotate the handle 2 to move the bolt 1 downward, and the bolt 1 Apply force to the spring 3 while moving down, and then apply pressure to the gland 4 elastically by the spring 3 to achieve the structure of bearing detection under pressure; when the spring 3 reaches the required spring force, measure the edge surface of the gland 4 and The distance H of the lower surface of the base 7 is calculated to obtain the height value of the bearing under pressure. Using this tool for detection, the pressure control is accurate and the error of the measurement value is small.

Compared with the prior art, the bearing height detection device under pressure of the utility model is simple in structure, small in shape, easy to use, easy to operate, small in measurement error, improves detection efficiency, and saves detection cost at the same time.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
