Description

Nylon retainer fixing device

Technical Field

The utility model relates to the field of instruments, in particular to a clamping and fixing device for a nylon retainer.

Background

The nylon retainer is used for guiding the steel balls, has great significance on the stability and long service life of the bearing, is not well fixed in the daily detection process because the nylon retainer is not provided with a special clamp, and is usually used for adhering and fixing the detected retainer by using glue, and the retainer is scrapped after the detection is finished. Based on this, a device for fixing nylon holders was developed.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model aims to provide a nylon retainer fixing device, which can well fix a retainer and has no damage after detection.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a nylon holder clamping fixing device, includes first clamping part, second clamping part, first clamping part and second clamping part cover are established on the screw rod, second clamping part has the opening, and this second clamping part passes through opening and screw rod dismouting, the one end that the screw rod corresponds second clamping part is provided with the flange that is used for the butt and restricts second clamping part and deviate from, and the other end threaded connection has the nut, be provided with the spring between nut and the first clamping part, first clamping part passes through spring and second clamping part cooperation and forms clamping structure.

As a further improvement of the utility model, one end of the second clamping part matched with the first clamping part is provided with convex columns which are uniformly distributed in the circumferential direction.

As a further improvement of the utility model, the opening of the second clamping part is in interference fit with the screw.

As a further improvement of the utility model, the upper end of the first clamping part is provided with an annular bulge for limiting the retainer.

As a further development of the utility model, the first clamping part is provided with a disk.

The utility model has the beneficial effects that: the whole structure is simple, the retainer can be reliably fixed, the detection efficiency of the retainer is improved, clamping damage to the retainer is avoided, and the detection cost is reduced.

Detailed Description

The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.

An embodiment of a nylon cage retainer apparatus of the present utility model is shown in fig. 1-2: including first clamping part 1, second clamping part 2, first clamping part 1 and second clamping part 2 cover are established on screw rod 3, second clamping part 2 has opening 4, and this second clamping part 2 passes through opening 4 and the dismouting of screw rod 3, the one end that screw rod 3 corresponds second clamping part 2 is provided with the flange 5 that is used for the butt and restricts second clamping part 2 and deviate from, and the other end threaded connection has nut 6, be provided with spring 7 between nut 6 and the first clamping part 1, first clamping part 1 passes through spring 7 and the cooperation of second clamping part 2 and forms clamping structure. The first clamping part 1 and the second clamping part 2 are sleeved on the screw rod 3, then the retainer to be tested is placed on the first clamping part 1, the second clamping part 2 which is selected to be matched is abutted against the retainer, the retainer pretightening force is controlled by adjusting the compression distance of the spring 7 through rotating the nut 6, after the retainer is measured, the first clamping part 1 is pressed down, and the retainer can be replaced after the second clamping part 2 is transversely pulled out.

The second clamping part 2 cooperates the one end of first clamping part 1 to be equipped with circumference equipartition projection 8, when second clamping part 2 butt holder, projection 8 butt is in the step face between two pockets of holder, sets up projection 8 and makes the atress of holder more even to obtain reliable fixed.

The opening 4 of the second clamping part 2 is in interference fit with the screw 3, so that the second clamping part 2 is primarily fixed and is not easy to rotate.

The upper end of the first clamping part 1 is provided with a plurality of annular bulges 9 for limiting the retainer, the annular bulges 9 are used for limiting the retainers with different sizes, and the first clamping part 1 is also provided with a disc 10 which is convenient to press downwards.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
