Abstract
The invention aims to provide a depth limiting drill bit for improving the drilling depth precision. The depth limiting drill bit comprises a drill handle, and an edge part mounted at the end of the drill handle; the key point is that the drill handle is provided with a thread, and a cylinder is mounted through fitting the thread; an annular guide rail with an inverted T-shaped section is arranged on the bottom surface of the cylinder; an annular depth limiting part is mounted on the annular guide rail in a sliding manner; and an annular groove with an inverted T-shaped section is formed in the top surface of the depth limiting part, and is used for fitting the annular guide rail. As the depth limiting drill bit is provided with the position-adjustable depth limiting part, the drill bit can be prevented from being fed too deeply so as to improve the drilling depth precision.
Description
Technical field
The invention belongs to bit technique field, be related specifically to a kind of depth stop drill bit.
Background technology
Utilizing in bit bore process, to drill bit continu to press, must could keep drill bit feeding.But when processing blind hole, have strict demand to the degree of depth of boring, operator is careless slightly, just likely makes blind hole depth exceed predetermined requirement, causes blind hole to be cancelled.And only train operator, it is unpractical for relying on the qualification of operator to solve this problem.
Summary of the invention
The object of the invention is to propose a kind of depth stop drill bit, to improve the accuracy of drilling depth.
Depth stop drill bit of the present invention comprises drillstock and is arranged on the blade of drillstock end, and key is that described drillstock is provided with screw thread, and is provided with a cylinder by threaded engagement; The bottom surface of described cylinder is provided with the ring-shaped guide rail that cross section is " ⊥ " shape, and described ring-shaped guide rail is slidably fitted with the depth stop portion of annular; The end face in depth stop portion is provided with the cannelure that cross section is " ⊥ " shape, for coordinating with ring-shaped guide rail.
When drilling blind hole, first regulate the position of the relative drillstock of cylinder according to predetermined blind hole depth, thus regulate the relative position of depth stop portion and drillstock, make the blind hole depth that the distance of bottom surface, depth stop portion and blade end equals predetermined, and then start boring.When drill bit is fed into predetermined blind hole depth, the end face of drilled material will contact with the bottom surface in depth stop portion, makes drill bit continue feeding, thus reaches the object regulating drilling depth.Because depth stop portion and cylinder are relative to rotating, therefore when depth stop portion contacts with the end face of drilled material, can't rotary drum be driven and affect the position of cylinder at drillstock.
Further, described drillstock is also provided with stop nut at the top position place in depth stop portion, this stop nut can carry out spacing to cylinder, and prevent cylinder from moving to the tail end of drillstock, thus ensure when depth stop portion contacts with the end face of drilled material further, can not rotary drum be driven and affect the position of cylinder at drillstock.
Depth stop drill bit of the present invention can the depth stop portion of adjusting position by arranging, and drill bit feeding can be avoided excessively dark, thus improve the accuracy of drilling depth.
Accompanying drawing explanation
Fig. 1 is the structural representation of depth stop drill bit of the present invention.
Fig. 2 is the working state schematic representation of depth stop drill bit of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the depth stop drill bit of the present embodiment comprises drillstock 1 and is arranged on the blade 2 of drillstock 1 end, and described drillstock 1 is provided with screw thread, and is provided with a cylinder 3 by threaded engagement; The bottom surface of described cylinder 3 is provided with the ring-shaped guide rail 4 that cross section is " ⊥ " shape, and described ring-shaped guide rail 4 is slidably fitted with the depth stop portion 5 of annular.The end face in depth stop portion 5 is provided with the cannelure 8 that cross section is " ⊥ " shape, for coordinating with ring-shaped guide rail 4.
When drilling blind hole, first regulate the position of the relative drillstock 1 of cylinder 3 according to predetermined blind hole depth, thus regulate depth stop portion 5 and the relative position of drillstock 1, make the blind hole depth that the distance of bottom surface, depth stop portion 5 and blade end equals predetermined, and then start boring.When drill bit is fed into predetermined blind hole depth, the end face of drilled material 6 will contact with the bottom surface in depth stop portion 5, makes drill bit continue feeding, thus reaches the object regulating drilling depth.Because depth stop portion 5 and cylinder 3 are relative to rotating, therefore when depth stop portion 5 contacts with the end face of drilled material 6, cylinder 3 can't be driven to rotate and affect the position of cylinder 3 at drillstock 1.
Further, described drillstock 1 is also provided with stop nut 7 at the top position place in depth stop portion 5, this stop nut 7 can carry out spacing to cylinder 3, and prevent cylinder 3 from moving to the tail end of drillstock 1, thus ensure when depth stop portion 5 contacts with the end face of drilled material 6 further, cylinder 3 can not be driven to rotate and affect the position of cylinder 3 at drillstock 1.
Claims (2)
1. a depth stop drill bit, comprises drillstock and the blade being arranged on drillstock end, it is characterized in that described drillstock is provided with screw thread, and be provided with a cylinder by threaded engagement; The bottom surface of described cylinder is provided with the ring-shaped guide rail that cross section is " ⊥ " shape, and described ring-shaped guide rail is slidably fitted with the depth stop portion of annular, and the end face in depth stop portion is provided with the cannelure of cross section for " ⊥ " shape, for coordinating with ring-shaped guide rail.
2. depth stop drill bit according to claim 1, is characterized in that described drillstock is also provided with stop nut at the top position place in depth stop portion.
