Abstract
The invention relates to a manufacturing method of a high-precision drilling tool. The manufacturing method of the high-precision drilling tool comprises the following steps that firstly, fine grinding is conducted on the bottom end face of a base; secondly, a supporting base is fixed to the end of the base; thirdly, a dovetail groove is linearly cut in the length direction of the supporting base, and the perpendicularity between the dovetail groove and the end face of the base is guaranteed; fourthly, a screw is installed on the side wall of the supporting base, and the screw stretches into the dovetail groove; fifthly, a positioning plate is linearly cut, so that a dovetail table is obtained; sixthly, linear cutting is conducted on the positioning plate, so that a positioning table is obtained; seventhly, drilling jig holes are drilled in the positioning plate, and drilling jigs are installed in the drilling jig holes; and eighthly, the dovetail table is arranged in the dovetail groove. According to the manufacturing method of the high-precision drilling tool, the structure is simple, using is flexible and convenient, clamping is easy, and the machining precision is high.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly for the manufacture method of the positioning fixture that workpiece is holed。
Background technology
Workpiece 1 as shown in Figure 1, it is rectangular configuration, center is with rectangular channel 12, now need its end face gets out hole 11, location, use common positioning instant to complete, but owing to the required precision of boring is higher, special frock must be used to position to it, and frock must be easy to use, clamping efficiency is high, can guarantee that again its machining accuracy simultaneously。
Summary of the invention
The present invention is directed to disadvantages mentioned above of the prior art, it is provided that the manufacture method of a kind of high-precision drilling hole tool, its simple in construction, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high。
The technical solution adopted in the present invention is as follows:
The manufacture method of high-precision drilling hole tool, comprises the steps:
The first step, carries out ground finish to the bottom face of base；
Second step, at the end fixed supporting seat of base；
3rd step, the length direction line along supporting seat cuts out dovetail groove, it is ensured that the perpendicularity of dovetail groove and base end face；
4th step, the sidewall at supporting seat installs screw, and screw stretches in dovetail groove；
5th step, line cutting location-plate obtains forked tail platform；
6th step, obtains positioning table to location-plate linear cutter；
7th step, gets out drill jig hole on location-plate, installs drill jig in described drill jig hole；
8th step, is placed in forked tail platform in dovetail groove。
It is an advantage of the current invention that: the structure according to workpiece, the location-plate of the band positioning table identical with workpiece centre groove structure is set, simultaneously on location-plate with forked tail platform in the dovetail groove of supporting seat, can the height of up-down adjustment location-plate, when being pressed downward against clamping of workpieces, by the drill jig on location-plate, workpiece is carried out Drilling operation, simple in construction, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high。
Accompanying drawing explanation
Fig. 1 is the structural representation of workpiece。
Fig. 2 and Fig. 3 is the structural representation of the present invention。
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described。
As shown in Figure 1 to Figure 3, the present invention includes base 2 and location-plate 6, and with supporting seat 3 on base 2, supporting seat 3 is vertical with dovetail groove 4, and supporting seat 3 sidewall is provided with screw 5, and screw 5 end is stretched in dovetail groove 4；Location-plate 6 sidewall is with forked tail platform 7, with positioning table 9 and drill jig 8 on location-plate 6, forked tail platform 7 is positioned at the dovetail groove 4 of supporting seat 3, when workpiece 1 is positioned, positioning table 9 coordinates with the rectangular channel 12 on workpiece 1, and location-plate 6 is pressed on the end face of workpiece 1, unscrews or tightening screw 5 can along the height of dovetail groove 4 up-down adjustment location-plate 6, when location-plate 6 is pressed in the end face of workpiece 1, by drill jig 8, workpiece is carried out Drilling operation；
The manufacture method of the present invention is as follows:
The first step, carries out ground finish to the bottom face of base 2；
Second step, at the end fixed supporting seat 3 of base 2；
3rd step, the length direction line along supporting seat 3 cuts out dovetail groove 4, it is ensured that the perpendicularity of dovetail groove 4 and base 2 end face；
4th step, the sidewall at supporting seat 3 installs screw 5, and screw 5 stretches in dovetail groove 4；
5th step, line cutting location-plate 6 obtains forked tail platform 7；
6th step, obtains positioning table 9 to location-plate 6 linear cutter；
7th step, gets out drill jig hole on location-plate 6, installs drill jig 8 in described drill jig hole；
8th step, is placed in forked tail platform 7 in dovetail groove 4。
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, within protection scope of the present invention, it is possible to do any type of amendment。
