Description

A kind of Furniture manufacturing bench drill

Technical field

The utility model belongs to furniture manufacturing field, and in particular to a kind of Furniture manufacturing bench drill.

Background technique

Bench drill can be placed on operation post, the vertically arranged small drilling machine of main shaft.In existing Furniture manufacturing, generally Drilling operation is carried out using bench drill, wherein counterbore can make inside screw terminal embedment plate, no protrusion part, to not change device Surface structure, improve the aesthetics of device, but existing counterbore is realized usually using drill bit through secondary operation, perforating efficiency It is low, and a kind of drill bit can only get a kind of counterbore of specification, the scope of application is small

In view of the deficiencies in the prior art, a kind of Furniture manufacturing bench drill is now needed, different diameter specifications can be easily got Counterbore, with improve working efficiency and improve drill bit the scope of application.

Utility model content

The purpose of the utility model is to provide a kind of Furniture manufacturing bench drills, can easily get the heavy of different diameter specifications Hole, to improve working efficiency and improve the scope of application of drill bit.

The utility model provides the following technical solution:

A kind of Furniture manufacturing bench drill, including table drill body, the table drill body are equipped with drill bit, and the drill bit includes first Drill bit, the second drill bit and third drill bit, first drill bit are set to the center of inside of second drill bit, and second drill bit is set There is the center of inside of the third drill bit, first bit diameter is less than the diameter of second drill bit, second drill bit Diameter be less than the diameter of the third drill bit, in the axial direction of first drill bit, second drill bit and the third drill bit Axis is located along the same line, and first drill bit, second drill bit and the third drill bit can opposite slidings.

Preferably, second drill bit and the third drill bit are hollow form, and the length of the third drill bit is less than The length of second drill bit.

Preferably, the periphery of second drill bit and the third drill bit is equipped with limit hole, and the limit hole is ellipse Shape, the limit hole is interior to be equipped with caging bolt.

Preferably, the two sides of second drill bit and the third drill bit are symmetrically equipped with the limit hole.

Preferably, the end cross-sectional of first drill bit is hexagon.

The utility model has the beneficial effects that

The utility model is slided by the way that the second drill bit and third drill bit are opposite, and the diameter and depth of counterbore can be changed, can be square Just the counterbore for getting different diameter specifications, improves work efficiency and improves the scope of application of drill bit.

Detailed description of the invention

Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:

Fig. 1 is the utility model structure chart；

In the figure, it is marked as the 1, first drill bit；2, the second drill bit；3, third drill bit；4, limit hole；5, caging bolt.

Specific embodiment

As shown in Figure 1, a kind of Furniture manufacturing bench drill, including table drill body, table drill body is equipped with drill bit, and drill bit includes the One drill bit 1, the second drill bit 2 and third drill bit 3, the first drill bit 1 are set to the center of inside of the second drill bit 2, and the second drill bit 2 is equipped with the The center of inside of three drill bits 3,1 diameter of the first drill bit is less than the diameter of the second drill bit 2, and the diameter of the second drill bit 2 is less than third brill The axial central axes of first 3 diameter, the first drill bit 1, the second drill bit 2 and third drill bit 3 are located along the same line, and the first drill bit 1, the second drill bit 2 and third drill bit 3 can opposite slidings；First drill bit 1, the second drill bit 2 and third drill bit 3 opposite can slide, and lead to It is fixed to cross caging bolt 5, the second drill bit 2 is exposed, counterbore can be got by the first drill bit 1 and the second drill bit 2；By the second drill bit 2 and the end of third drill bit 3 counterbore of another specification can be got by the first drill bit 1 and third drill bit 3 to it；And pass through cunning Dynamic second drill bit 2 and third drill bit 3, can be changed the depth of counterbore, improve work efficiency and improve the scope of application of drill bit.

Wherein, the second drill bit 2 and third drill bit 3 are hollow form, and the length of third drill bit 3 is less than the second drill bit 2 Length, so convenient for being mutually shifted between drill bit.The periphery of second drill bit 2 and third drill bit 3 is equipped with limit hole 4, limit Hole 4 is ellipse, and caging bolt 5 is equipped in limit hole 4, easy to remove by limit hole 4, by caging bolt, improves and fixes Firm and convenience.The two sides of second drill bit 2 and third drill bit 3 are symmetrically equipped with limit hole 4, so can further improve Fixed stability.The end cross-sectional of first drill bit 1 is hexagon, so being assemblied on machine convenient for drill bit.

The working method of the utility model:

As shown in Figure 1, the first drill bit 1, the second drill bit 2 and third drill bit 3 opposite can slide, it is fixed by caging bolt 5, Second drill bit 2 is exposed, counterbore can be got by the first drill bit 1 and the second drill bit 2；By the end of the second drill bit 2 and third drill bit 3 Portion can get the counterbore of another specification by the first drill bit 1 and third drill bit 3 to it；And pass through the second drill bit 2 of sliding and the Three drill bits 3 can be changed the depth of counterbore, improve work efficiency and improve the scope of application of drill bit.

The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
