Description

Simple thread punching point safety tool

Technical Field

The utility model relates to an anchor clamps for screw thread dashes some insurance belongs to the structural design field in being applied to the mechanical assembly field.

Background

The airplane structure and the system are fixedly connected by a large number of bolts, each bolt has the safety requirement correspondingly, and the most common bolt safety mode is C-shaped punching point safety. The punching points required by the C-type insurance are arranged at the small diameter of the thread, and the three punching points are distributed at 120 degrees. At present, points are punched on the threads directly by sharp punch, and the method has the following defects: 1. the point is easy to punch on the end surface of the nut during punching, so that the nut is damaged. The point punch is easy to slip when punching points, and pits are punched on the product, so that the surface quality of the product is damaged. 2. In the point punching process, the three points are difficult to form 120 degrees, particularly in the structures with narrow spaces and poor passages, the point punching difficulty is high, and the point punching angle difficulty is higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that exists among the prior art, provide a but accurate screw thread insurance dashes the position of some and dashes the simple and easy screw thread of some angle each other and dash some insurance instrument.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a simple thread point punching safety tool comprises a guide model, wherein a blind hole and 3 guide holes are formed in the guide model, internal threads are arranged in the blind hole, and a thread to be point punched safety is connected with the blind hole; the 3 guide holes are distributed at an angle of 120 degrees and are used for inserting the sharp punch, and the sharp head of the sharp punch is contacted with the thread.

Preferably, the upper end face of the nut matched with the threads is attached to the end face of the blind hole.

Preferably, a handle is arranged at the end part of the guide model far away from the blind hole, so that the guide model is convenient to hold.

Preferably, the handle is screwed with the guide form.

Compared with the prior art, the utility model has the advantages of as follows:

1. the problems of accurate position of a bolt punching point center and punching point angle can be effectively solved.

2. The punching tool is simple to operate, can effectively guarantee punching safety quality, and prevents the sharp punch from damaging nuts and products.

Detailed Description

It should be noted that, in the present embodiment, the terms "up and down" and the like are all described according to the drawings, and do not limit the present invention.

The present invention will be described in further detail with reference to the accompanying drawings 1-2: a simple thread punching point safety tool comprises a handle 1 and a guide model 2, wherein the upper end of the handle 1 is used for being held by workers, the lower end of the handle 1 is provided with a groove, and an internal thread is arranged in the groove; the upper end of the guide model 2 is provided with a bulge with external threads, and the bulge is matched with the groove, so that the handle 1 is fixed with the guide model 2 in a threaded connection manner; the blind hole with internal threads and 3 guide holes are formed in the guide model 2, the blind hole is located at the lower end of the guide model 2 and used for screwing in a threaded end of a bolt 4 to be punched for point security, the guide holes are communicated with the blind hole, the open end of each guide hole is located on the side face of the guide model, the sharp punch 3 is inserted into each guide hole, the sharp head of each punch point is in contact with the corresponding thread, and the included angle between the 3 guide holes is 120 degrees.

As a preferred embodiment of the embodiment, the axial center of the handle 1 and the axial center of the blind hole are on the same straight line.

In order to effectively ensure the safety quality of the punching point, the upper end surface of the nut matched with the thread is attached to the end surface of the blind hole, namely, the sharp point of the sharp punch 3 directly acts on the middle position of the attachment surface of the bolt and the nut.

The using method comprises the following steps:

(1) according to the diameter of the bolt, a guide model 2 with the same inner diameter is arranged on the handle 1;

(2) sleeving the guide model 2 on the bolt 4, and screwing the guide model to ensure that the end face of the guide model 2 is attached to the upper end face of the nut;

(3) the nibs 3 are placed in the guide holes of the guide matrix 2 so that the tips of the nibs 3 are in contact with the threads.

(4) And knocking the sharp punch 3 to complete the thread punching point safety.

(5) The sharp punch 3 is taken out, and the guide model 2 is unscrewed.

The above embodiments are merely further descriptions of the present invention, and do not constitute limitations of the present invention. Any extension and modification made by those skilled in the art without departing from the principle of the present invention are within the protection scope of the present invention.
