Abstract
The utility model discloses a drill box. A box body is a square block made of No. 45 steel; three waist-shaped holes are formed in the right part of the box body side by side and from front to back, and penetrate the top surface and the bottom surface of the box body; a clamping gap is formed in the left part of the box body and includes a left horizontal section and a right circular section, the left end of the left horizontal section extends to the left end surface of the box body, the right end of the left horizontal section is connected with the right circular section, and the central lines of the two sections are located on a same straight line; the top surface of the box body is a combined plane of which the middle is lower than the left part and the right part, and the middle of the top directly faces the left part and the right part; three screw through holes are formed in the left part of the top surface of the box body side by side and from front to back; threaded holes corresponding to the three screw through holes are respectively formed in the box body below the clamping gap. The drill box has the advantages that a drill bit is positioned through the right circular section of the clamping gap, and is tightly clamped through screws penetrating the screw through holes, so that the drill bit can be effectively fixed for mounting and prevented from rotating.
Description
Technical field
The utility model relates to a kind of box, and this box is used for fixing drill bit.
Background technology
Drill bit is a kind of conventional cutter, and this drill bit is generally fixed by standard drill chuck and the workbench of outsourcing at present.The defect of mounting means is now: the clamping force of drill chuck is inadequate, and drill bit easily produces rotation, and drill bit so just can not be installed securely, is badly in need of solving above-mentioned technical barrier for this reason.
Utility model content
Technical problem to be solved in the utility model is to provide the box of the firm installation drill bit of a kind of energy.
The technical solution of the utility model is as follows: a kind of box, comprise box body (1), it is characterized in that: described box body (1) is square block, its material is No. 45 steel, and before and after the right part of box body (1), have side by side three mounting holes (2), this mounting hole runs through end face and the bottom surface of box body (1); The left part of described box body (1) has one and clamps breach (3), this clamping breach (3) runs through the front and back sides of box body (1), and formed by left horizontal segment (3a) and right circle section (3b), wherein the left end of left horizontal segment (3a) is opened to the left side of box body (1), the right-hand member of this left horizontal segment is connected with right circle section (3b), and this center line of two sections is on same straight line; Described box body (1) end face is the combined planar that middle part is low, left and right portion is high, before and after the left part of this box body (1) end face, have side by side three screw via holes (4), and upper corresponding these three the screw via holes (4) of box body (1) that clamp below breach (3) have screwed hole.
The utility model positions drill bit by the right circle section (3b) that clamps breach (3), and by being located in screw in screw via hole (4) by drill bit banding, so just can fixedly mount well drill bit, prevent that drill bit from rotating, and the utility model is simple in structure, be easy to processing.
As preferably, the width of described left horizontal segment (3a) is 2-3mm, and the length of left horizontal segment (3a) is 22-28mm, and the radius of described right circle section (3b) is 12-16mm.
In this case, the width of described left horizontal segment (3a) can not be excessive, again can not be too small, and large easy fracture, little easily causes elasticity inadequate.
As further preferred, the width of described left horizontal segment (3a) is 2.5mm, and the length of this left horizontal segment (3a) is 25mm, and the radius of described right circle section (3b) is 14mm.
In order to strengthen structural strength, prevent fracture, the left part of described box body (1) end face and its middle part are by the arc surface smooth transition of epirelief, and the middle part of this box body (1) end face is by lower protruding arc surface and its right part smooth transition.
Beneficial effect: the utility model positions drill bit by the right circle section (3b) that clamps breach (3), and by being located in screw in screw via hole (4) by drill bit banding, so just can fixedly mount well drill bit, prevent that drill bit from rotating, and the utility model is simple in structure, be easy to processing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of box, comprises box body 1, and this box body 1 is square block, and its material is No. 45 steel, and the bottom surface of this box body 1 is plane.And, before and after the right part of described box body 1, having side by side three mounting holes 2, this mounting hole 2 runs through end face and the bottom surface of box body 1, and box body 1 is fixed by being located in bolt in these three mounting holes 2 and the workbench of drilling machine.
The left part of described box body 1 has one and clamps breach 3, this clamping breach 3 runs through the front and back sides of box body 1, and formed by left horizontal segment 3a and right circle section 3b, wherein the left end of left horizontal segment 3a is opened to the left side of box body 1, the right-hand member of this left horizontal segment 3a is connected with described right circle section 3b, and this center line of two sections is on same straight line.The width of described left horizontal segment 3a is 2-3mm, and the length of left horizontal segment 3a is 22-28mm, and the radius of described right circle section 3b is 12-16mm.As preferably, the width of described left horizontal segment 3a is 2.5mm, and the length of this left horizontal segment 3a is 25mm, and the radius of described right circle section 3b is 14mm.
