Abstract

The utility model relates to a movable central trunnion, which is particularly applied to the installation of a pneumatic actuator element (cylinder) in the pneumatic industry, and is characterized bycomprising a main body, four press blocks and screws, wherein the main body is respectively provided with a small shaft on the upper part and the lower part, and the main body and the four press blocks are tightened by the screws. The utility model has simple, compact and reasonable structure, can effectively solve the problem of the prior art, can be applied to the existing standard cylinder andvarious non-standard cylinders, solves the technical defect of the movement of the prior central trunnion, and enlarges the application range.

Description

Removable central gudgeon

Technical field

The utility model relates to a kind of removable central gudgeon, specifically can be applicable to the installation of the pneumatic apparatus-cylinder of pneumatic industry.

Background technique

In prior art, pneumatic apparatus-cylinder normally adopts the Cock screw mounting structure, and mainly there is following problem in it: 1, grasp is not enough, the executive component sliding transfer that is easy to generate in service.2, two installation shaft concentricitys cannot say for sure to demonstrate,prove (dividing body structure as adopting).3, integral rigidity can not guarantee.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of removable central gudgeon, can be suitable for pneumatic industry existing standard cylinder and all kinds of nonstandard cylinder, solve in the past the technological deficiency that exists aspect moving at central gudgeon, and can enlarge its use field.

According to the technological scheme that the utility model provides, removable central gudgeon comprises that main body, four briquettings, screws form, and described main body is respectively equipped with little axle up and down, and it is fastening that main body and four briquettings pass through screw.

Described screw 4 adopts 8～16.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Can effectively solve above prior art existing problems, can be suitable for pneumatic industry existing standard cylinder and all kinds of nonstandard cylinder, solution in the past central gudgeon move aspect the technological deficiency of existence, enlarge its use field.

Embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

Embodiment one

As Fig. 1～shown in Figure 2, the removable central gudgeon of A type

Main body 1 is an integral body, and main body 1 median pore radius is identical with the cylinder external diameter, and main body 1 is respectively equipped with little axle 5 up and down, is used for fixing in the workplace.At four briquettings 2 of 1 four jiaos of stack mountings of its main body, be tightened to one with 16 screws 4, make the air cylinder tie rod 6 that is installed in briquetting 2 and the main body 1 common formation hole fixing simultaneously.

As Fig. 3～shown in Figure 4, the removable central gudgeon working principle of A type: unclamp 16 screws, central authorities' gudgeon just can move forward and backward at the pull bar that is prolonging cylinder (dotted line partly), moves on to the position that needs, and tightens screw and just can firmly firmly grasp air cylinder tie rod 6 and keep this position.

Embodiment two

As Fig. 5～shown in Figure 6, the removable central gudgeon of Type B

Main body 1 is an integral body, and main body 1 median pore radius is identical with the cylinder external diameter, and main body 1 is respectively equipped with little axle 5 up and down, is used for fixing in the workplace.At four briquettings 2 of 1 four jiaos of stack mountings of its main body, be tightened to one with 8 screws 4, make the air cylinder tie rod 6 that is installed in briquetting 2 and the main body 1 common formation hole fixing simultaneously.

As Fig. 7～shown in Figure 8, the removable central gudgeon working principle of Type B: unclamp 8 screws, central gudgeon just can move forward and backward at the pull bar that is prolonging cylinder (dotted line partly), moves on to the position that needs, and tightens screw and just can firmly firmly grasp air cylinder tie rod and keep this position.

Cylinder is as the standard components and parts, under the constant situation of its standard installation dimension, adopts this structure can effectively enlarge its using scope.Except that being applied to pneumatic industry, the similar removable central gudgeon structure of other industry.

Claims

1, a kind of removable central gudgeon is characterized in that: comprise main body (1), four briquettings (2), described main body (1) is respectively equipped with little axle (5) up and down, and main body (1) is fastening by screw (4) with four briquettings (2).

2, removable central gudgeon according to claim 1 is characterized in that described screw (4) adopts 8～16.
