Abstract

The utility model provides a simple checking device for concentricity of a push rod, and relates to a push rod checking device. A lower block (13) is of a square structure, an upward extending block (12) is arranged on one side of the lower block (13) of the square structure, the lower block (13) and the upward extending block (12) form an L-shaped structure, an upper notch (2) is formed from the upper end surface to the lower part of the upward extending block (12), mutually corresponding bores (8) are respectively formed from the two side walls to the outer surfaces of the upper notch (2), a side notch (3) is formed from the other end surface to the middle part of the lower block (13), and a pin shaft is inserted into the two mutually corresponding bores (8). According to the utility model, a push rod stub shaft and a connection head are placed in the upper notch and the side notch, and whether the concentricity of the push rod stub shaft and the connection head meets the requirement is judged according to the condition whether the connection head can be placed in the side notch; and by adopting the simple structure, the simple checking device can rapidly and accurately detect the concentricity of the push rod.

Description

A kind of simple and easy verifying attachment of push rod concentricity

[technical field]

The utility model relates to a kind of verifying attachment of push rod, especially relates to a kind of simple and easy verifying attachment of push rod concentricity.

[background technology]

Known; On plant equipment, many times all to use shaft-like workpiece; Certain requirement is all arranged adding the concentricity of man-hour to shaft-like workpiece, therefore after producing this type of workpiece, all will the concentricity of bar be detected, whether main detection reaches desired concentric standard; Detect relatively simply for the concentricity of simple shaft-like workpiece, want complicated many but carry out detecting operation for the shaft-like workpiece of bending; At present many to the detecting instrument of shaft-like concentricity; Like: dial gauge, three coordinate measuring machine or high-accuracy special-purpose concentricity surveying instrument or the like,, aforementioned detecting instrument whether adheres to specification though can detecting the concentricity of institute's processing work comparatively accurately; But described checkout equipment price general charged is relatively more expensive; And complicated operation; Need power supply mostly; Detection efficiency is low, especially in large batch of production, not only is difficult to finish the work efficiently, and the testing staff of workpiece product is equipped with and equipment control etc. all need drop into a large amount of personnel, fund.

[summary of the invention]

In order to overcome the deficiency in the background technology; The utility model provides a kind of simple and easy verifying attachment of push rod concentricity; Can the simple and easy verifying attachment of said push rod concentricity be put into connector by the side gap and judge that the concentricity of push rod spindle nose and connector meets the requirements through putting into push rod spindle nose and connector respectively in last gap and the side gap; The utility model is through simple structure, but the concentricity of accurate detection push rod.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of simple and easy verifying attachment of push rod concentricity; Comprise bottom piece, extend upward block and bearing pin, the said bottom piece structure that is square is provided with in bottom piece one side of square structure and extends upward block; Said bottom piece with extend upward block and form " L " shape structure jointly; Said upper surface to the bottom that extends upward block is provided with gap, and said two side to the exterior face of going up gap is respectively equipped with the perforation of mutual correspondence, is provided with the side gap at other end end face to the middle part of bottom piece; In two mutual corresponding perforation, insert bearing pin.

One side the simple and easy verifying attachment of described push rod concentricity is at any pin-and-hole that is provided with up/down perforation of said bearing pin.

Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:

The simple and easy verifying attachment of the said push rod concentricity of the utility model is provided with perforation respectively through being arranged on the two side that extends upward block; Pass the axis hole of perforation, push rod spindle nose inner bearing successively by bearing pin; Then the connector of the push arm other end is put into the side gap; If connector is put into the side gap smoothly and is proved that just the concentricity of push rod spindle nose and connector meets the requirements; If connector distortion occurs or tilts can not put into smoothly when putting into the side gap, prove that then the concentricity of push rod spindle nose and connector is undesirable; The utility model is through simple structure, but the concentricity of accurate detection push rod; The utility model has overcome defectives such as expensive, complicated operation, the efficient of existing checkout equipment is low, the utlity model has simple in structure, easy to operate, efficient advantages of higher.

[embodiment]

Can explain the utility model in more detail through following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope, and the utility model is not limited to following embodiment;

Simple and easy verifying attachment in conjunction with the push rod concentricity described in accompanying

drawing

1,2 or 3; Comprise bottom piece 13, extend upward block 12 and bearing pin 10; Said bottom piece 13 structure that is square; Be provided with in bottom piece 13 1 sides of square structure and extend upward block 12, said bottom piece 13 with extend upward block 12 and form " L " shape bearing 1 structure jointly, said upper surface to the bottom that extends upward block 12 is provided with gap 2; Said two side to the exterior face of going up gap 2 is respectively equipped with the perforation 8 of mutual correspondence, is provided with side gap 3 at other end end face to the middle part of bottom piece 13; In two each other corresponding perforation 8, insert bearing pin 10, one side at any pin-and-hole 9 that is provided with up/down perforation of said bearing pin 10.

Implement the simple and easy verifying attachment of the described push rod concentricity of the utility model; Through being fixed on the push rod spindle nose 4 of push arm 6 one ends in the gap 2 through bearing pin 10, pass the axis hole 5 of perforation 8, push rod spindle nose 4 inner bearings 11 successively by bearing pin 10, consider that landing may appear in bearing pin 10; The utility model is provided with pin-and-hole 9 in bearing pin 10 1 sides; Can guarantee the pinning push rod spindle nose 4 that bearing pin is stable through nail or split pin, the connector 7 of push arm 6 other ends is put into, if connector 7 can be put into the side gap 3 of bottom piece 13; Then show the push rod spindle nose 4 at push arm 6 two ends and the standard that connector 7 meets concentricity; If connector 7 can not be put into side gap 3 smoothly, then show the push rod spindle nose 4 at push arm 6 two ends and the standard that connector 7 does not meet concentricity, when push rod spindle nose 4 and connector 7 do not meet the standard of concentricity; Can realize the purpose of said adjustment concentricity through the angle of adjustment push arm 6, push rod is adhered to specification.

The utility model does not detail part and is prior art.
