Abstract
The utility model belongs to the field of tool design and manufacture technology, which relates to a drill tool design characterized in that the hole shape of a thin plate is drilled by utilizing an ordinary driller. The drill tool for a thin plate, which is provided by the utility model is composed of a drill shank, a drill head, and a positioning drill head. The front end of the drill head adopts a drill tooth structure in a saw tooth shape. The head of the positioning drill head is slightly longer than that of the drill tooth of the drill head. The drill tool provided by the utility model which can be used for hole shape processing for a small quantity of thin plates of the single element and an electrical and mechanical maintenance industry has the advantages of simple structure and easy application.
Description
The utility model belongs to the instrument design field, relates to a kind of drilling tool design that utilizes common rig drilling thin plate pass.
In non-standard equipment is made, because small lot or single-piece production, processing is not easy to design frock and carries out stamped, at present method manufacturings of adopting Twist Drill, manual reaming more for the thin plate pass, it is low but also make crudy not high to do not only efficient like this, has caused technical difficulty.
The purpose of this utility model is to overcome the above-mentioned deficiency in the prior art, and a kind of Drilling tool for thin plate that is applicable to the processing of single and mini-batch production thin plate pass is provided.
Basic ideas of the present utility model are that a kind of drilling tool that bores the tooth machining that adopts of design carries out the processing of thin plate pass, thereby realize the purpose of this utility model.
Accompanying drawing one has provided a kind of realization drilling tool structure figure of the present utility model.
Accompanying drawing two bores the structural representation of tooth for drilling tool.
In accompanying drawing one: (1), drillstock (2), drill bit (3), weld seam (4), brill tooth (5), location drill bit (6), trip bolt
Describe the utility model in detail below in conjunction with accompanying drawing:
The utility model is made up of drillstock (1), drill bit (2), location drill bit (3) three parts.Drill bit is welded as a whole by bit part and brill toothed portion, and same drillstock (1) is threaded, and location drill bit (5) is connected by trip bolt (6) with drillstock.A little grows the head of bit drills tooth the head of location drill bit, to guarantee the location.With electric hand drill or bench drill drill chuck clamping usefulness, drill bit is for machining usefulness for drilling tool for drillstock, and the location drill bit is used for the processing location.The front end of drill bit adopts the brill toothing (shown in accompanying drawing two) of sawtooth pattern, and process is finished by boring the tooth cutting, is different from the drilling processing of current use fully.It is little that it has the processing driving force, and the aperture is smooth, characteristics such as precision height.
The utility model can bore the big or small specific design drill bit and the drillstock thereof of panel hole according to need in concrete the use, the size dimension of location drill bit, satisfying the concrete needs that use, following table has provided the size of the drill bit of 10 kinds of dimensions and supporting drillstock thereof, location drill bit, available reference.
| Bit diameter (mm) | 16.5;?19;?20.5 | 23;?25.5;?30.5;?35.5 | 40.5;?50.5;?60.5 |
| Drillstock diameter (mm) | 7 | 10 | 16 |
| Location bit diameter (mm) | 5 | 6 | 8 |
When using the utility model, at first drillstock and drill bit screw thread are connected, will locate drill bit and drillstock connects by trip bolt, form drilling tool, again with the drilling tool clamping on the drill chuck of bench drill or electric hand drill, the locating hole on the drill bit steel plate of location, the boring of can spudding in.
The utility model is simple in structure, implements easily, and is respond well, can be widely used in the single-piece or small lot thin plate pass machining and dynamo-electric maintenance industry in the non-standard equipment manufacturing.
Claims (4)
1, a kind of Drilling tool for thin plate is characterized in that this drilling tool is made up of drillstock, drill bit, location drill bit.
2, a kind of Drilling tool for thin plate as claimed in claim 1, the front end that it is characterized in that drill bit adopts the brill toothing of sawtooth pattern.
3, a kind of Drilling tool for thin plate as claimed in claim 1, it is characterized in that locating drill bit head a little grow in the head of bit drills tooth.
