Abstract
The utility model mainly relates to a machine tool, in particular to a split type hole forming drill. The drill comprises a drill bit and a drill handle, wherein the drill bit is located at one end of the drill handle, and the drill bit and the drill handle are of a split type structure. The split type hole forming drill is of the split type structure, and thus is convenient to assemble and disassemble, the drill bit is convenient and fast to replace, and production efficiency is promoted. Besides, a guide pillar is arranged in the center of the drill bit, accurate positioning of a machined hole can be ensured, and machining accuracy of machining of a product can be promoted.
Description
Technical field
The utility model relates generally to a kind of machine tool, especially relates to a kind of split type stroke of hole drill.
Background technology
Stroke hole drill that uses now adopts diamond dust to electroplate and forms, and drill bit and drillstock mostly are integral structure greatly, loading and unloading so in use are trouble very, relatively wastes man-hour, and behind bit wear, whole stroke of hole drill all will be scrapped, and cause very big waste, increase processing cost; The present in addition hole drill bit central place of drawing does not have lead, and the location is inaccurate when causing machining hole, and machining accuracy is not high.
The utility model content
Goal of the invention of the present utility model is to overcome the defective that prior art exists, thereby realizes split type stroke of hole drill.
For achieving the above object, the technical solution of the utility model is: a kind of split type stroke of hole drill, comprise drill bit and drillstock, and described drill bit is positioned at an end of drillstock, and described drill bit and drillstock are split-type structural.
Drill bit is cylindric, and the excircle of drill bit one end partly is evenly equipped with circular-arc drilling sword, and described bit central place has the suitable tapped through hole of size; Described drillstock comprises handle body end and abutting end, described abutting end is two sections concentric cylinders, the abutting end diameter is provided with the external screw thread that mates with the drill bit tapped through hole than the face of cylinder of large cylinder, described handle body end is single diameter circle cylinder, and described handle body end cylinder diameter is greater than all cylindrical diameters of abutting end.
Described drillstock abutting end is with after drill bit cooperates, and drillstock abutting end diameter stretches out drill bit drilling sword end face than small cylinder and forms lead.
Drilling sword on the described drill bit adopts the carborundum fillet to electroplate and forms.
The end face of described lead is provided with the suitable chamfering of size, and it is convenient to enter processing parts, can not cause workpiece to scratch.
The beneficial effects of the utility model:
1. split type stroke of hole drill of the present utility model adopts split-type structural, and assembly and disassembly is convenient, and more bit change is convenient and swift, enhances productivity.
2. split type stroke of hole drill of the present utility model is provided with lead at the bit central place, can guarantee the accurate location of machining hole, improves the machining accuracy of converted products.
3. split type stroke of hole drill of the present utility model when drill bit and drillstock appearance damage, only changed part of damage and got final product, and can also continue to use as long as another satisfies service condition, can not cause waste, shortens the process-cycle of renewal part, saves cost.
4. split type stroke of hole drill of the present utility model, drillstock and lathe coupling part more do not need dismounting during bit change, reduce wear, and increase the service life.
Description of drawings
Fig. 1 is the structural representation of split type stroke of hole drill;
Fig. 2 is the left TV structure schematic diagram of Fig. 1;
Fig. 3 is the drill bit broken section structural representation of split type stroke of hole drill;
Fig. 4 is the drillstock structural representation of split type stroke of hole drill.
The specific embodiment
Also by specific embodiment split type stroke of hole drill of the present utility model done more detailed description below in conjunction with accompanying drawing.
Embodiment:
Referring to Fig. 1-Fig. 4: 1-drill bit, 101-drilling sword, 102-tapped through hole, 2-drillstock, 201-handle body end, 202-abutting end, 203-external screw thread, 204-lead.
Split type stroke of hole drill of the present utility model comprises drill bit 1 and drillstock 2, and described drill bit 1 is positioned at an end of drillstock 2, and described drill bit 1 and drillstock 2 are split-type structural.
Drilling sword 101 on the drill bit 1 adopts the carborundum fillet to electroplate and forms.
The end face of lead 204 is provided with the suitable chamfering of size.
Claims (4)
1. split type stroke of hole drill comprises drill bit and drillstock, and described drill bit is positioned at an end of drillstock, it is characterized in that: described drill bit and drillstock are split-type structural; Described drill bit is cylindric, and the excircle of drill bit one end partly is evenly equipped with circular-arc drilling sword, and described bit central place has the suitable tapped through hole of size; Described drillstock comprises handle body end and abutting end, described abutting end is two sections concentric cylinders, the abutting end diameter is provided with the external screw thread that mates with the drill bit tapped through hole than the face of cylinder of large cylinder, described handle body end is single diameter circle cylinder, and described handle body end cylinder diameter is greater than all cylindrical diameters of abutting end.
