Abstract
The utility model relates to a novel tapping location device, used matching with the pistol electric drill and the tap, and used for the tap location when tapping. It comprises three thimbles 1, a guide holder 2, a reset spring 3, and a sliding sleeve 4. Three thimbles 1 are uniformly distributated downwards and connected to the periphery of the lower end face of the guide holder 2. The lower end of the sliding sleeve 4 is inserted into the central hole of the guide holder 2, and the upper end is exposed outside the guide holder 2 and provided with a flange 4-1. The reset spring 3 is equipped between the lower end faces of the sliding sleeve 4 and the flange 4-1 and the upper end face of the guide holder 2. Because the utility model is adopted with three thimbles to locate, after the tapping, the surface quality of the tapping is good, and the assurance of the vertical degree of the center of the screw thread hole with the surface of the workpiece can be obtained. The tapping quality is high, and the efficiency is high.
Description
Technical field:
The utility model relates to a kind of tapping positioner.With pistol electric drill and the supporting use of screw tap, the screw tap location when being used for tapping.
Background technology:
Tapping method commonly used at present is following several:
1, for generally than small workpiece, the tapping of punching on radial drilling machine needs more time clamping of cost and smoothing;
2, for big workpiece, mainly use magnetic force to bore manual tapping after the perforating, often tapping rear thread hole perpendicularity can not guarantee, causes doing over again even scrapping;
3, have relatively high expectations and add man-hour than strength member, be subjected to device-restrictive, the punching tapping all must be finished on radial drilling machine.Because clamping workpiece and smoothing are all comparatively difficult, efficient is very low.And big workpiece often occurs lathe is collided, cause damage.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of tapping rear thread hole perpendicularity can be guaranteed, tapping quality height, novel tapping positioner that efficient is high.
The purpose of this utility model is achieved in that a kind of novel tapping positioner, it comprises: three thimbles, guide holder, back-moving spring and sliding sleeves, three downward uniform guide holder lower surface peripheries that are connected in of thimble, insert in the guide holder centre bore sliding sleeve lower end, the upper end is exposed guide holder and is shaped on flange, between slop-on flange lower surface and guide holder upper surface back-moving spring is set.
Because the utility model adopts three thimble location, after the tapping, the tapping surface quality is good, and screwed hole center and surface of the work perpendicularity can be guaranteed, tapping quality height, efficient height.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is an embodiment schematic diagram of the present utility model.
The specific embodiment:
Referring to Fig. 1, the utility model is a kind of novel tapping positioner.Mainly form by three thimbles 1, guide holder 2, back-moving spring 3 and sliding sleeve 4.
Three thimble 1 downward uniform guide holder 2 lower surface peripheries that are connected in, sliding sleeve 4 lower end straight drum part are inserted in guide holder 2 centre bores, with guide holder 2 matched in clearance, to guarantee to rotate flexibly oiling.Sliding sleeve 4 bottoms are exposed and are set circlip for shaft 5 on the outside wall surface of part of guide holder 2 and carry out axial location.The part that guide holder 2 is exposed on sliding sleeve 4 tops has flange 4-1, in order to embed and tight fit with pistol electric drill front end boss.Center, the guide holder 2 upper surface flange 2-1 that is provided with protruding upward, in order to the flange 4-1 axial location of sliding sleeve 4 upper ends.Back-moving spring 3 both can adopt a big spring directly to be placed on sliding sleeve 4 and the guide holder 2 flange 2-1.Also can adopt two or three little springs, the little spring lower end is embedded on guide holder 2 upper surfaces, and the upper end contacts with sliding sleeve 4 flange 4-1.
Use step and principle referring to Fig. 2:
1, screw tap is inserted the electric drill chuck, and have Key jaw type spanner fastening.
2, with novel tapping positioner, embed with pistol electric drill front end boss, and close-fitting.
3, tapping positioner thimble is placed workpiece 7 surfaces, and guarantee that all contact with working face at 3.
4, gently move the tapping positioner, make screw tap 8 targeting parts enter the tapping bottom outlet, and align the center.
5, start tapping electric drill 6, and assurance is just changeed, low speed.
6, the tapping electric drill slides along guide holder, to the tapping hole degree of depth, and stops the tapping electric drill.
7, adjust the counter-rotating of tapping electric drill, low speed, and start.
8, screw tap withdraws from and enters next tapping process.
