Description

[Detailed Description of the Invention] The present invention relates to a device for fixing a wrapper guide when introducing a raw material or raw pipe into a drilling machine or a polishing machine.

This wrapper guide needs to be replaced every time the pipe size changes, which is often the case.

Also, due to its nature, it is necessary to firmly guide the raw pipe passing inside.

In other words, it must be easy to replace in a short time, and must be firmly fixed.

Conventionally, it has been known to directly press down from above with a cylinder, or to fix by sandwiching it with a link mechanism.

With this method, the fixing force was weak, and when replacing the wrapper guide, the fixing device was located at the top, making it difficult to remove it with a crane.

This invention is a new fixing device for a wrapper guide installed on the entrance table of a drilling machine or a pipe polishing machine, and its construction will be explained below with reference to an embodiment shown in the drawings.

1 is a wrapper guide, 2 is a hole punching machine or a pipe polishing machine body, 3 is an entrance table, 4 is a wedge, 5 is a link lever, and 6 is a hydraulic cylinder.

The wrapper guide 1 is fixed onto the entrance table 3 by a wedge 4, and the wedge 4 is slid in the horizontal direction by a hydraulic cylinder 6 via a link lever 5.

Reference numeral 7 indicates an inclined engagement protrusion provided at the lower end of the wrapper guide 1 and has an inclined surface facing toward the main body 2 side, and 8 indicates an entry side having an inclined surface that engages with the inclined surface of the inclined engagement protrusion 7. This is an inclined engagement recess provided in the upper part of the table 3.

9 is a mounting part provided integrally at the bottom of the bugle guide 1;
It can be inserted into the entrance table 3 from above, and has a hole 10 having a slope that engages with the wedge surface 4a of the wedge 4.

The wedge 4 is inserted from the side of the entrance table 3, and as shown in FIG. 1, the wedge 4 is inserted with an inclination so that the direction of the fastening force exerted by the wedge surface 4a is applied both horizontally and vertically.

That is, as shown in Fig. 1, the wedge surface 4a is
The wedge 4 is driven so that it is inclined at an angle θ toward the side.

Therefore, the inclined surfaces of the holes 10 provided in the mounting portion 9 also face in the same direction.

As a result, when the wedge 4 is inserted, the wedge surface 4a applies a horizontal force H and a vertical force ■ to the wrapper guide 1,
The mounting portion 9 is firmly fixed in both directions.

When the wedge 4 is inserted by the hydraulic cylinder 6 through the link lever 5, the wrapper guide 1 is pushed in the direction of the drilling machine or tube polishing machine main body 2, and the inclined engagement protrusion 7 firmly contacts the inclined engagement recess 8. to engage.

In this way, the bugle guide 1 is horizontal to the entrance table 3.
Firmly fixed with pressure in both vertical directions.

The hydraulic cylinder 6 pushes the wedge 4 via the link lever 5, and furthermore, due to the wedge action, a strong fixing force is generated and strong fixing is possible.

Once fixed, due to the nature of the wedge 4, it will not come out even if an external force is applied to the wrapper guide 1 to try to pull it out.

When replacing the wrapper guide 1, it can be easily attached and detached using the hydraulic cylinder 6.

According to the present invention, the trumpet guide 1 can be firmly fixed both horizontally and vertically, eliminating troubles during operation and reducing replacement time.

These improvements will improve operating rates, simplify maintenance and inspection, etc.
The contribution of this device is significant.
