Technical Field

The utility model relates to the technical field of machining tools, in particular to a universal drilling positioning tool.

Background

In the field of machining, especially in connection of plates, beams, attachment seats and other parts, it is often necessary to perform hole matching. The hole site is marked by a marker pen usually by manpower during drilling, but because the error is larger, the center of the hole cannot be found accurately generally, and the situation that two workpiece hole sites cannot be aligned after drilling is frequently caused, so that means such as reaming and re-drilling are required to process, the efficiency is low, the reamed workpiece is also not attractive, the strength of connection can be influenced, and the quality problem is caused.

Therefore, we propose a general purpose drilling positioning tool in order to solve the problems set forth above.

Disclosure of utility model

The present utility model is directed to a universal drilling positioning tool, which solves the above-mentioned problems.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a universal borehole positioning tool, comprising: the conical head is slidably arranged in the shell, and a step-shaped shoulder is arranged at the joint of the shell and the conical head;

The core body is arranged in the shell in a sliding way;

the upper end of the shell is in threaded connection with a gland, and the gland covers the core;

the lower end head of the core body penetrates through the central hole of the conical head, and the upper end of the core body penetrates through the gland;

the core body is provided with a rebound device.

Preferably, the bottom of the shell is provided with a flange structure.

Preferably, the rebound device is specifically a spring, the spring is sleeved outside the core body, the lower end of the spring is propped against the conical head, and the upper end of the spring is propped against a convex edge designed on the upper part of the core body.

Compared with the prior art, the utility model has the beneficial effects that:

The automatic centering device has the advantages of simple structure, few parts, convenience in processing, simplicity and rapidness in operation, and capability of automatically finding the center of the round hole through the conical surface of the conical head and the flange surface of the shell, and being applicable to automatic centering of round holes with multiple specifications due to continuous change of the diameter of the section of the conical head along the axial direction, thereby improving the universality.

Drawings

Fig. 1 is a schematic structural view of the present utility model.

In the figure: 1. a housing; 2. a conical head; 3. a core; 4. a spring; 5. a gland; 6. a processed member; 7. and (5) processing a workpiece.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the present utility model provides a technical solution: a universal borehole positioning tool, comprising: the conical head 2 is slidably arranged at the lower end of the inner part of the shell 1, the conical head faces downwards, step-shaped shoulders are arranged at joint positions of the shell 1 and the conical head 2 and are used for limiting the position of the conical head 2 in the shell 1, and a central hole is formed in the middle of the conical head 2 in a penetrating mode;

the upper end of the shell 1 is in threaded connection with a gland 5 for closing the inner cavity of the shell 1;

The core body 3 is arranged in the shell 1 in a sliding way, the lower end head of the core body 3 penetrates through the central hole of the conical head 2, and the upper end of the core body 3 penetrates through the gland 5;

The spring 4 is sleeved outside the core body 3, the lower end of the spring 4 is abutted against the conical head 2, the upper end of the spring 4 is abutted against a convex edge designed on the upper part of the core body 3, and the gland 5 compresses the core body 3;

the conical head 2 and the core 3 can slide in the compression direction of the spring 4 under the action of external force;

when the tool is used, the conical head 2 of the tool is firstly inserted into a hole of a machined piece 6, the conical surface is pressed against the edge of the hole, then the shell 1 is pressed, the flange at the bottom of the shell 1 is tightly attached to the plane of a workpiece, at the moment, the conical head 2 is concentric with the hole, and then the upper end of the hammer core 3 is used for marking the circle center of a well-formed hole on the machined piece 7;

When the core body 3 moves downwards, the spring 4 is compressed, and when the core body 3 is not stressed, the spring 4 is reset to automatically rebound and lift the core body 3, so that the next hammering is facilitated.

What is not described in detail in this specification is prior art known to those skilled in the art.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
