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.
1, 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 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), middle circle section (3b) and right horizontal segment (3c), wherein the left end of left horizontal segment (3a) is opened to the left side of box body (1), this left horizontal segment is connected with the left end of right horizontal segment (3c) by described middle circle section (3b), and this center line of three 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, and the middle part of end face is just to described right horizontal segment (3c), and before and after the left part of 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 middle 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) equates with the width of right horizontal segment (3c), and be 2-3mm, and the length of left horizontal segment (3a) is 22-28mm, and the length of described right horizontal segment (3c) is 10-16mm; The radius of described middle circle section (3b) is 12-16mm.
In this case, the width of the width of described left horizontal segment (3a) and right horizontal segment (3c) can not be excessive, again can not be too small, and large easy fracture, little easily causes elasticity inadequate.
As further preferably, the width 2.5mm of the width of described left horizontal segment (3a) and right horizontal segment (3c), and the length of left horizontal segment (3a) is 25mm, and the length of described right horizontal segment (3c) is 12mm; The radius of described middle 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 middle 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
