Abstract
The invention relates to a hole positioning fixture comprising a positioning pin with a bottom snapped into a recess on a workbench. The hole positioning fixture is characterized in that the width of the positioning pin is larger than the width of every hole on a workpiece requiring positioning; chamfers are provided on two sides of the top of the positioning pin, such that bevels are formed; a spring is supported between the positioning pin and the bottom of the recess on the workbench. For holes with different calibers on the workpiece, with the fixture provided by the invention, two sides of a hole is snapped on the bevels of the positioning pin; when the workpiece continues to be pressed down, the spring is contracted, such that the hole is positioned. Therefore, holes with any calibers can be snapped on the bevels of the positioning pin, and the positioning fixture provided by the invention can be adapted to holes with any caliber. Processing difficulty is greatly reduced, and positioning speed is improved.
Description
Technical field
The present invention relates to a kind of tool that the perforate on the workpiece is positioned of being used for.
Background technology
For workpiece as shown in Figure 11, need position the perforate on it 2.During the location, tool such as Fig. 2 of employing are said, comprise that the bottom embeds the alignment pin 4 in the workbench 3, tend to wear a set bolt 5 in order to fixed locating stud 4 in the alignment pin 4, and the bottom of set bolt 5 screws in the workbench 3.
During the location, the perforate 2 of workpiece 1 is inserted in the alignment pin 4, realize the location.Its shortcoming is obvious, and promptly the size of alignment pin 4 must closely cooperate with the size of perforate 2, must make different alignment pins 4 for the perforate 2 of different size; Improved machining accuracy so greatly; And, need waste time and energy for the different alignment pin 4 of different perforates 2 processing.
Summary of the invention
The purpose of this invention is to provide a kind of localization tool that can be fit to the perforate of virtually any size.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of hole localization tool; Comprise alignment pin, the bottom of alignment pin snaps in the groove on the workbench, it is characterized in that: the width of said alignment pin is greater than the width of all perforates on the workpiece to be positioned; Thereby have chamfering in the both sides at said alignment pin top and form the inclined-plane, between the bottom portion of groove of said alignment pin and workbench, be supported with spring.
Preferably, in said alignment pin, be equipped with bolt, the bottom of bolt screws in the said workbench, and said spring is wrapped in outside the screw rod of bolt.
For the perforate of different bores on the workpiece, adopt tool provided by the invention after, the both sides of perforate are stuck on the inclined-plane of alignment pin, when workpiece was continued to press down, spring shrank, thereby perforate is positioned.This shows that no matter the perforate of which kind of bore can be stuck on the inclined-plane of alignment pin, therefore, localization tool provided by the invention can adapt to the perforate of any bore, greatly reduces difficulty of processing, has improved the speed of location.
Description of drawings
Fig. 1 is a workpiece sketch map to be positioned;
Fig. 2 is existing localization tool sketch map;
A kind of hole localization tool sketch map of Fig. 3 for providing among the embodiment 1;
A kind of hole localization tool sketch map of Fig. 4 for providing among the embodiment 2.
The specific embodiment
For making the present invention more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 3; A kind of hole provided by the invention localization tool; Comprise alignment pin 6, the bottom of alignment pin 6 snaps in the groove on the workbench 3, and the width of alignment pin 6 is greater than the width of all perforates 2 on the workpiece 1 to be positioned; Thereby have chamfering in the both sides at said alignment pin 6 tops and form the inclined-plane, between the bottom portion of groove of alignment pin 6 and workbench 3, be supported with spring 7.
In conjunction with Fig. 1, during the location, behind the perforate 2 aligned pins 6 with workpiece 1,, make perforate 2 be stuck on the inclined-plane of alignment pin 6 both sides with workpiece 1 pressed downward, continue to press down workpiece 1, spring 7 shrinks, and continues to press down workpiece 1 and props up workbench 3 until workpiece 1, accomplishes the location.
As shown in Figure 4, the difference of present embodiment and embodiment 1 is, in alignment pin 6, is equipped with bolt 8, and the bottom of bolt 8 screws in the workbench 3, and spring 7 is wrapped in outside the screw rod of bolt 8.Other structures and working method are identical with embodiment 1.
Claims (2)
1. hole localization tool; Comprise alignment pin (6); The bottom of alignment pin (6) snaps in the groove on the workbench (3); It is characterized in that: the width of said alignment pin (6) is gone up the width of all perforates (2) greater than workpiece to be positioned (1), at said alignment pin (6) thus the both sides at top have chamfering forms the inclined-plane, between the bottom portion of groove of said alignment pin (6) and workbench (3), be supported with spring (7).
2. a kind of hole as claimed in claim 1 localization tool is characterized in that: in said alignment pin (6), be equipped with bolt (8), the bottom of bolt (8) screws in the said workbench (3), and said spring (7) is wrapped in outside the screw rod of bolt (8).
