Abstract
The utility model discloses an adjustable positioning drill, comprising a depth limit sleeve at least one section of which is in bolt connection with a drill bit and a tight nut which is arranged on the back end of the depth limit sleeve to adjust the working length of the drill bit and limit the depth of a borehole. The utility model freely adjusts the working length of the drill bit by means of the depth limit sleeve in bolt connection with a straight shank twist drill, thereby effectively solving the problem of control of the depth of the borehole, avoiding the quality problem of out-of-tolerance faulty parts caused by uneasy control of the depth of the borehole by means of manual experience operations, and improving the reliability of the size control of the borehole.
Description
Technical field
The utility model relates to a kind of drill bit cutter of drilling part, in particular for the drill bit that uses in the assembling boring processing.
Background technology
Normally used straight shank twist drill all is to clamp the staight shank of fluted drill directly to part enforcement boring with the three-jaw drill chuck when boring in machining.No matter be employing pneumatic drill or machining equipment, boring is nearly all driven straight in, and the degree of depth of boring all is the degree of depth by artificial experience is grasped and continuous size measures is come keyhole.If when between assembling boring processing two interlayers, holing, operating personnel are in order to injure the surface of lower floor, and the degree of depth of keyhole very carefully is even if know a thing or two the control operation workman, also be difficult to the surface that control does not injure second layer part, quality problems occur.
Summary of the invention
The weak point of the wayward drilling depth of the purpose of this utility model prior art straight shank twist drill, provide a kind of can free adjustment drill bit active length, can be the adjustable location drilling drill bit of controlling the location according to drilling depth,
The utility model realizes that the technical solution of above-mentioned purpose is: a kind of adjustable location drilling drill bit, comprise the straight shank twist drill body, it is characterized in that, comprise that also one has at least one section to be screwed onto the degree of depth spacing collar on the drill bit and to be assemblied in degree of depth spacing collar rear end cooperation adjustment drill bit active length, the clamp nut of restriction drilling depth.
The utility model has following beneficial effect than prior art.
Locate reliable, swift and convenient to operate.Can by the degree of depth stop collar on the straight shank twist drill that is spirally connected, just can freely adjust the active length of drill bit according to drilling depth, thereby solve the size Control of drilling depth effectively.Avoid artificial experience to operate wayward drilling depth, caused the quality problems of overproof faulty part easily.Improved the reliability of drilling quality.The accuracy and the convenience of its free adjustment drill bit active length are specially adapted to assemble the boring that the pneumatic drill controlling depth is located, and can satisfy the assembling boring requirement.
Description of drawings
Fig. 1 is a structural texture cross-sectional schematic of the present utility model.
The specific embodiment
Fig. 1 has described the utility model and has mainly bored first most preferred embodiment by being screwed onto the adjustable location drilling that parallel shank twist drill 3 and degree of depth spacing collar 1 form.Be shaped on screw thread parallel shank twist drill 3 external screw threads that are spirally connected at the straight handle section of parallel shank twist drill 3.Degree of depth spacing collar 1 endoporus is shaped on internal thread, or be shaped on one section unthreaded hole that cooperates parallel shank twist drill 3 external screw threads and the screw thread that is spirally connected in its back-end, promptly the front end at degree of depth spacing collar 1 can have one section unthreaded hole that connects the rear end internal thread, to regulate the drill bit active length and further to advance the long free degree in location.Can there be one to cooperate the locking nut 2 of adjusting the drill bit active length in the rear end of degree of depth spacing collar 1.During work drill bit packed in the degree of depth spacing collar 1, as required, use length, use nut 2 with its locking then, the location drilling processing work by threaded adjusting.
Claims (2)
1. adjustable location drilling drill bit, comprise the straight shank twist drill body, it is characterized in that, comprise that also one has at least one section to be screwed onto the degree of depth spacing collar on the drill bit and to be assemblied in degree of depth spacing collar rear end cooperation adjustment drill bit active length, the clamp nut of restriction drilling depth.
2. adjustable location drilling drill bit according to claim 1 is characterized in that, the front end of degree of depth spacing collar has one section unthreaded hole that connects the rear end internal thread.
