Abstract

The utility model relates to the filed of devices for processing car couplers, in particular to a punch with an iron pushing hole and an iron pushing rotary stopper for a car coupler, which comprises a punch body, a power end and a handle body. The power end is arranged at the bottom of the punch body. The handle body is connected with the power end which is in a taper shape. Accordingly, the punch enters from one end of the iron pushing hole and is taken out from the other end of the iron pushing hole, thereby resolving the problems of roundness of the iron pushing hole and the coaxiality between the iron pushing hole and the iron pushing rotary stopper, effectively improving quality of the surface of the iron pushing hole and assembling quality of products, resolving the problem that the punch is broken during work simultaneously, prolonging service life of the punch and reducing labor strength of operating staffs.

Description

Coupler body pushes away the iron hole and pushes away iron rotational stop drift

Technical field

The utility model relates to coupler body processing unit (plant) field, and especially a kind of coupler body pushes away the iron hole and pushes away iron rotational stop drift.

Background technology

Coupler body pushes away the iron hole and pushes away iron rotational stop casting surface and need adopt drift to clear up, former drift is location backstop drift, be provided with location backstop in the punch body lower end in order to make the drift top not break the lock iron guide post of hole upper end, in punch process, after the backstop of drift is run into hole end surface, drift need back withdraw, after need applying the cross force reaming, just can withdraw from by drift drift in the process of rollback, drift is broken can't be taken out in the hole, and cause the roundness in hole not reach requirement, influence pushes away the normal rotation of iron.

Summary of the invention

In order to overcome the existing iron hole drift easy fracture that pushes away, influence the deficiency of the roundness in hole, the utility model provides a kind of coupler body to push away the iron hole and has pushed away iron rotational stop drift.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of coupler body pushes away the iron hole and pushes away iron rotational stop drift, comprise punch body, power end and handle body, power end is positioned at the punch body bottom, and the handle body is connected power end, and power end adopts conical design.

The beneficial effects of the utility model are, power end adopts conical design, drift is entered from an end that pushes away the iron hole, the other end takes out, and has solved the roundness that pushes away the iron hole and has pushed away axiality problem between the iron rotational stop, has improved the quality that pushes away the iron hole surface and the assembling quality of product effectively, simultaneously, also solve the problem that drift ruptures in the course of the work, in the service life of having improved drift, alleviated operating personnel's labour intensity.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is a work schematic diagram of the present utility model.

1. punch bodies among the figure, 2. power end, 3. handle body, 4. coupler body 5. pushes away the iron hole, 6. pushes away the iron rotational stop, 7. lock iron guide post.

The specific embodiment

As Fig. 1 is schematic diagram of the present utility model, Fig. 2 is a work schematic diagram of the present utility model, a kind of coupler body pushes away the iron hole and pushes away iron rotational stop drift, comprise punch body 1, power end 2 and handle body 3, power end 2 is positioned at punch body 1 bottom, handle body 3 is connected power end 2, and power end 2 adopts conical design.

This drift has been cancelled the location backstop of former drift, and in power end 2 employing conical design, power end 2 with contact towards rifle, punch body 1 is entered with the axis direction that pushes away iron rotational stop 6 along pushing away iron hole 5 all the time, guaranteeing effectively to clear up pushing away iron hole 5 and pushing away on the basis of the protruding meat of scab etc. of iron rotational stop 6 casting surfaces of coupler body 4, avoid lock iron guide post 7 is caused damage, can make drift unblank to take out from the other end that pushes away iron hole 5 under the prerequisite of iron guide post 7 allowing simultaneously again.

Claims

1. a coupler body pushes away the iron hole and pushes away iron rotational stop drift, comprise punch body (1), power end (2) and handle body (3), power end (2) is positioned at punch body (1) bottom, and handle body (3) is connected power end (2), it is characterized in that: power end (2) adopts conical design.
