Description
Technical field
The utility model relates to a kind of machine tooling equipment, is specifically related to a kind of boring machine hole processing device, is suitable for the tapping of various common boring machines to the large-scale workpiece upper screwed hole, belongs to the Machining Technology field.
Background technology
At present, in medium-sized and small enterprises, for the processing of internal thread on the workpiece, we adopt three kinds of methods usually.The one, to the screwed hole below the M10, adopt electric hand drill to bore bottom outlet, pincers worker tapping then; The 2nd, for adopting drilling machine processing more than the M10 and less than the screwed hole of M64, this also is the method for the most frequently used machining screw; The 3rd, screwed hole bigger than normal then adopts the method for choosing button.To the screwed hole of big workpiece, under the prerequisite that processing conditions allows, also can adopt magnetic drill press to process.But, on some large-scale workpieces, the special screwed hole in position particularly, above method just can't realize the processing in double thread hole.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art; A kind of boring machine hole processing device is provided; This device comprises boring spindle and the machine tap that is attached thereto, and in the described boring spindle knife bar is arranged, and is connected with the end axle through pin; Scroll chuck is by being bolted on the end axle, and screw tap is clamped by scroll chuck through spacer shell.This device utilizes simple production equipment to accomplish when production and processing, and is convenient to load and unload cutter in use, and is suitable for the application of various common boring machines to the tapping of large-scale workpiece upper screwed hole.
The utility model is realized with following technical scheme: a kind of boring machine hole processing device; This device comprises boring spindle and the machine tap that is attached thereto; It is characterized in that: in the described boring spindle knife bar is arranged, the knife bar front end has groove and opening, and knife bar is connected with the end axle through pin; The other end of described end axle has scroll chuck, through being bolted on the end axle; Described scroll chuck is through the fastening screw tap of spacer shell.
Described end axle endoporus and spacer shell tip engages are also located, and clamped by scroll chuck, locking screw tap in the spacer shell.
Described knife bar rear end is the Mohs conical surface, and the knife bar front end is connected with the end axle via pin.
The utility model has the advantages that: this apparatus structure is simple, easy operating, and through facts have proved, the method is simple and easy to do, is a kind of effective method of utilizing common boring machine machining large workpiece upper screwed hole, and has reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain:
Fig. 1 is the utility model structural representation;
Among the figure: 1, boring spindle, 2, knife bar, 3, pin, 4, the end axle, 5, bolt, 6, scroll chuck, 7, spacer shell, 8, screw tap.
The specific embodiment
As shown in the figure: a kind of boring machine hole processing device; The machine tap 8 that this device comprises boring spindle 1 and is attached thereto; Knife bar 2 is arranged in the described boring spindle, and the knife bar front end has groove and opening, and knife bar is connected with end axle 4 through pin 3; The other end of described end axle has scroll chuck 6, is fixed on the end axle through bolt 5; Described scroll chuck is through spacer shell 7 fastening screw taps 8.
Described end axle (4) endoporus and spacer shell (7) tip engages are also located, and clamped by scroll chuck, locking screw tap (8) in the spacer shell.
Described knife bar (2) rear end is the Mohs conical surface, and the knife bar front end is connected with end axle (4) via pin (3).
The course of work: before the tapping, go out the thread Pilot hole on the workpiece, utilize this device to carry out tapping processing then in subdrilling on the boring machine.The described knife bar rear end Mohs conical surface needs match grinding, and front end is connected with the end axle via pin, transmits the moment of torsion that main axis rotation is brought through pin, and simultaneously, the end axle drives pin and in keyway, axially is free to slide under the effect of cutting force, and realizes the feed motion of cutter.
Claims (3)
1. boring machine hole processing device; The machine tap (8) that this device comprises boring spindle (1) and is attached thereto; It is characterized in that: knife bar (2) is arranged in the described boring spindle, and the knife bar front end has groove and opening, and knife bar is connected with end axle (4) through pin (3); The other end of described end axle has scroll chuck (6), is fixed on the end axle through bolt (5); Described scroll chuck is through the fastening screw tap of spacer shell (7) (8).
2. a kind of boring machine hole processing device according to claim 1 is characterized in that: described end axle (4) endoporus and spacer shell (7) tip engages are also located, and clamped by scroll chuck, locking screw tap (8) in the spacer shell.
