Description

Clamping detection device of miniature bearing nylon retainer

Technical Field

The invention relates to the technical field of bearing parts, in particular to a clamping detection device for a nylon retainer of a miniature bearing.

Background

The nylon retainer is a common part of the bearing, and the precision of the nylon retainer is an important index of the service life of the bearing. At present, the method for detecting the flexible parts in the industry is less, mainly non-contact, and has higher requirement on the surface quality of a detected object, and the contact detection needs to control the deformation of parts, so that the detection result has high randomness and poor operation stability. The nylon retainer installation location at present adopts the mode of pasting to fix at the test rack, carries out detection such as circularity and profile by the inspector again, and this kind of form efficiency is lower, is unfavorable for the location of nylon retainer, and the operation is also very inconvenient simultaneously.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the clamping detection device of the nylon retainer of the miniature bearing, which has a simple and reasonable integral structure and effectively clamps the nylon retainer.

In order to achieve the purpose, the invention provides a clamping detection device of a nylon retainer of a miniature bearing, which comprises a base and at least two pressure rods, wherein a positioning column is arranged on the base, an elastic sheet used for enabling the pressure rods to abut against pockets of the nylon retainer to be positioned is arranged on the positioning column, one end of each pressure rod is connected with the positioning column through the elastic sheet, and the other end of each pressure rod is arranged in a ball head shape.

The beneficial effect who so sets up is: set up like this, place the nylon holder on the base, through the depression bar that sets up in the reference column both sides for the bulb of depression bar is contradicted in the holder pocket hole, thereby realize the location to the nylon holder, the person of being convenient for inspecter carries out detection such as circularity and profile, and the depression bar has the flexure strip simultaneously, can guarantee the conflict effect through the flexure strip, and this kind of structure overall cost is low, and frock manufacturing, convenient to use are applicable to the multiple precision detection clamping of holder, and the testing result accuracy is high.

As a further arrangement of the invention, the positioning column is separately arranged to form a connecting column and a rotating column, the connecting column is in threaded fit with the base, an insertion opening and a rotating shaft are arranged between the connecting column and the rotating column, the insertion opening and the rotating shaft are rotatably connected to form the connection between the rotating column and the connecting column, and the elastic piece is arranged on the rotating column.

The beneficial effect who so sets up is: set up like this, can realize the ascending of spliced pole or descend through rotating the spliced pole to the ascending adjustment of depression bar direction of height to the nylon holder of the different model sizes of adaptation, the reference column components of a whole that can function independently sets up simultaneously, and the rotation of spliced pole can not influence the position of the depression bar on the rotation post, guarantees the depression bar and supports the stability of pressing, and this kind of simple structure does benefit to the realization.

As a further arrangement of the invention, a positioning ring groove is arranged on the inner wall of the insertion opening, a positioning flange is arranged on the outer wall of the rotating shaft, and the positioning flange is matched with the positioning ring groove to form a limit for the separation of the rotating column.

The beneficial effect who so sets up is: set up like this, avoid rotating post and spliced pole in the use, the pine takes off appears, guarantees overall structure's stability, does not influence simultaneously and rotates, and overall structure is also very simple, does benefit to the realization.

As a further arrangement of the invention, the compression bar is mirror-polished.

The beneficial effect who so sets up is: the pressing rod is arranged in such a way, the pressing rod is more smooth and clean, the friction of the ball head is smaller, the nylon retainer is not easily abraded, and meanwhile, the nylon retainer is convenient to process and beneficial to implementation.

Detailed Description

The embodiment of the clamping detection device of the micro bearing nylon retainer of the invention is shown in figures 1 and 2: including base 1 and two piece at least depression bars 4, be provided with reference column 2 on the base 1, be provided with on the reference column 2 and be used for conflicting the flexure strip 3 in the nylon retainer pocket hole of waiting to fix a position 4 of depression bar, 4 one ends of depression bar are passed through flexure strip 3 and are connected with

reference column

2, 4 other ends of depression bar are the bulb setting. The beneficial effect who so sets up is: set up like this, place the nylon holder on base 1, through the depression bar 4 that sets up in 2 both sides of reference column, make depression bar 4's bulb contradict in the holder pocket hole, thereby realize the location to the nylon holder, the person of being convenient for inspects carries out detection such as circularity and profile, depression bar 4 has flexure strip 3 simultaneously, can guarantee the conflict effect through flexure strip 3, this kind of structure is overall with low costs, the frock is made, convenient to use, be applicable to the multiple precision detection clamping of holder, the testing result accuracy is high.

As a further arrangement of the invention, the positioning column 2 is separately provided with a connecting column 21 and a rotating column 22, the connecting column 21 is in threaded fit with the base 1, an insertion opening and a rotating shaft 211 are arranged between the connecting column 21 and the rotating column 22, the insertion opening and the rotating shaft 211 are rotatably connected to form the connection between the rotating column 22 and the connecting column 21, and the elastic piece is arranged on the rotating column 22. The beneficial effect who so sets up is: set up like this, can be through rotating spliced pole 21, with shifting up or decline of spliced pole 21, realize the ascending adjustment of depression bar 4 direction of height to the nylon holder of the different model sizes of adaptation, 2 components of a whole that can function independently settings of reference column simultaneously, the rotation of spliced pole 21 can not influence the position of depression bar 4 on the rotation post 22, guarantees the stability that depression bar 4 supported the pressure, and this kind of simple structure does benefit to the realization.

As a further arrangement of the present invention, a positioning ring groove is disposed on an inner wall of the insertion opening, a positioning flange 212 is disposed on an outer wall of the rotating shaft 211, and the positioning flange 212 and the positioning ring groove are matched to form a spacing for the rotating column 22 to come off. The beneficial effect who so sets up is: by the arrangement, the rotation column 22 and the connecting column 21 are prevented from being loosened in the using process, the stability of the whole structure is guaranteed, the rotation is not influenced, and the whole structure is very simple and is beneficial to implementation.

As a further development of the invention, the pressure lever 4 is mirror-polished. The beneficial effect who so sets up is: by the arrangement, the pressing rod 4 is smoother, the friction of the ball head is smaller, the nylon retainer is not easily abraded, and the nylon retainer is convenient to machine and beneficial to implementation.

The above example is only one of the preferred embodiments of the present invention, and general changes and substitutions by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
