Description

Drilling operation tool capable of simply replacing drill bit

Technical Field

The utility model relates to a drill bit and screw tap quick change device technical field relates to a drilling operation instrument that can simply change drill bit particularly.

Background

The drill bit is made of diamond micro powder and hard alloy materials integrally, so that the drill bit not only has the high hardness and wear resistance of diamond, but also has the strength and the impact toughness of the hard alloy, is an extremely excellent cutting tool, and is widely used in the geological exploration fields of buildings, decorations, well drilling and the like.

The machining of common holes in production needs to comprise a plurality of steps, for example, the machining of threaded holes needs to be replaced between different drill bits and screw taps, and the common quick-change chucks on the market need special chucks connected with a machine tool, and particularly, the labor intensity of workers is high due to the fact that some heavy chucks can be used in the production process; the clamp body of the tool (drill bit, screw tap, etc.) adopts circular connection and needs a special rotation-stopping power transmission device, etc.

SUMMERY OF THE UTILITY MODEL

In view of the above problems in the prior art, an aspect of the present invention is to provide a drilling tool capable of easily replacing a drill, and more particularly, to a drilling tool capable of changing the outer diameter of a tool (a drill, a tap, etc.) into a uniform non-circular outer diameter through a tool holder having a non-circular outer diameter, and connecting the non-circular outer diameter to a machine tool holder to transmit power, thereby completing the processes of drilling, tapping, etc. of a part. It is characterized by portability and quickness.

Technical scheme

In order to achieve the above object, the utility model provides a pair of drilling operation tool that can simply change drill bit includes:

a machine tool clamp body;

the tool clamp comprises two tool clamp bodies, wherein shaft holes formed in the middle shafts of the two tool clamp bodies are different in size, a first tool and a second tool are movably inserted in the tool clamp bodies respectively, and the tool clamp bodies are fixed through screws in threaded connection with the outer walls;

the tool clamp is positioned in a round hole of the machine tool clamp body and is fixed through an anti-falling screw arranged at the bottom of the machine tool clamp body.

Preferably, the two tool clamp bodies have the same size and specification, and the outer walls of the two tool clamp bodies are provided with aligning fixture blocks and embedded into the round holes of the machine tool clamp bodies.

Preferably, the first tool and the second tool have different specifications.

Advantageous effects

Compared with the prior art, the utility model provides a pair of drilling operation instrument that can simply change the drill bit, transmission power part adopt non-circular connection structure simple reliable. The labor intensity is greatly reduced due to light weight, and the tool is suitable for the labor post with frequent replacement of tools (drill bits, screw taps and the like); the special chuck connected and matched with the machine tool is not needed, and the traditional drill chuck is adopted, so that the overall practical cost is reduced.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

This document provides an overview of various implementations or examples of the technology described in this disclosure, and is not a comprehensive disclosure of the full scope or all features of the disclosed technology.

fig. 3 is a schematic view of the overall structure of the present invention.

The main reference numbers:

1. a machine tool clamp body; 2. a screw; 3. a tool holder body; 4. an anti-drop screw; 5. a first tool; 6. a machine tool; 7. tool number two; 9. and aligning the fixture block.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of the word "comprising" or "comprises", and the like, in this disclosure is intended to mean that the elements or items listed before that word, include the elements or items listed after that word, and their equivalents, without excluding other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

Referring to fig. 1-3, a drilling tool with a replaceable drill bit includes a machine tool holder 1, two tool holders 3 with different bore diameters at the center axis, and a machine tool 6.

As shown in fig. 1 and 2, the specifications of the first tool 5 and the second tool 7 are different, so the device provided by the present invention can be used for producing drills with different specifications, specifically, a drill to be processed is inserted into a shaft hole formed in the center of the tool holder 3, and the screw 2 screwed on the outer wall is rotated by a screwdriver to fix the drill to be processed.

As can be seen from fig. 1, the tool holder 3 is inserted into the circular hole at the bottom of the machine tool holder 1 through the aligning fixture block 9 on the tool holder 3, so that the problem of drill bit rotation is prevented when a drill bit to be machined is machined, after the tool holder 3 is inserted into the circular hole at the bottom of the machine tool holder 1, the tool holder 3 is fixed by the rotation anti-drop screw 4, the tool holder is prevented from dropping from the circular hole, and then the machine tool holder 1 is fixed on the machine tool 6, so that tapping operation is performed.

In addition, if the drilling depth is shallow or tapping is performed in production, the anti-falling screw 4 in fig. 3 is not needed when the axial falling force of the workpiece on the tool in tool withdrawal is small, the magnetized machine tool fixture body can take out the tool (a drill bit, a screw tap and the like) by magnetic force, and the operation is more convenient.

The electrical components presented in the document are all electrically connected with an external master controller and 220V mains, and the master controller can be a conventional known device controlled by a computer or the like.

It will be appreciated by those skilled in the art that other similar connecting means, such as welding, bonding or screwing, may also be used to implement the present invention.

The above embodiments are merely exemplary embodiments of the present invention, which is not intended to limit the present invention, and the scope of the present invention is defined by the appended claims. Various modifications and equivalents may be made by those skilled in the art to the present invention without departing from the spirit and scope of the invention, and such modifications and equivalents should be considered to be within the scope of the invention.
