Abstract
In available lathe and other machine tool, three-jaw chuck and four-jaw chuck are used separately for holding circular material and material of other shapes and the chuck replacement is labour and time consuming and impairs machining accuracy. The present invention, multipurpose three-jaw chuck, has the functions of both available three-jaw chuck and four-jaw chuck, and its use can reduce labour strength and time and raise the centering accuracy in machining.
Description
The invention belongs to mechanical industry
The used dop of lathe on the mechanical industry before this, all adopt two kinds of chucks of three-jaw and four paws to come the clamping processing parts, three-jaw is the centering chuck, center as clamping circular pieces commonly used, four-jaw independent chuck then processes eccentric part in addition for clamping and square hole, part garden is in addition used, often often to process parts such as some above-mentioned off-centre at work, therefore often to pull down three-jaw chuck, change four-jaw independent chuck, need change three-jaw chuck again after processing off-centre or irregular part, successively will pull down four times, so often pull down, very effort influences lathe and three-jaw chuck centering precision again, yet will process eccentric element and irregular part is through common occurrence, as its appearance of machine-tool-lathe of mechanical industry so far, three-jaw chuck and four-jaw independent chuck are leveraged to the present always all over the world.
This multipurpose three-jaw chuck mainly contains centering eccentric three-jaw of three-jaw (1) (6) and collet body (5) and incense coil chain wheel (2) and eccentric three-jaw clamping screw (7) and constitutes.
Fig. 1 be Fig. 2 cut open figure to view and A-A office.
Fig. 2 is that figure cuts open in vertical view and the office of Fig. 1.
For the ease of understanding the present invention, be described below with reference to accompanying drawing:
With reference to Fig. 1, three centering three-jaws (1) are existing chuck three-jaw commonly used, it is installed in top three branch grooves such as grade (10) all around of garden shape collet body (5), the incense coil chain wheel (2) that its underpart has tooth and its to be placed in the garden shape collet body (5) matches, this incense coil chain wheel (2) is with existing identical, its underpart has the awl tooth to be distributed in collet body (5) three clamping cone teeth (3) all around with five equilibrium and to match, and clamping cone tooth (3) intersects uniform with five equilibrium groove (10).A garden shape gland (4) commonly used is arranged at the bottom of incense coil chain wheel (2), incense coil chain wheel (2) is pushed down, it is moved down, with reference to Fig. 1,2 in three left sides of waiting branch groove (10), an eccentric clamping screw (7) that is microscler I-shaped shape respectively is equipped with in the bottom, eccentric jaw (6) also is installed in three five equilibrium grooves (10), this off-centre jaw (6), top is identical with four paws commonly used, but its underpart does not have the half-nut ring, wait the eccentric clamping screw (7) of bottom, branch groove (10) left side to match and the half-nut ring is arranged on the left of its underpart and be installed in three, a breach (11) is convenient to clamp square part in addition on the folder spy portion millable of eccentric jaw (6), and the screw (9) on the collet body (5) is as the usefulness that the balance auxiliary block is installed.Five equilibrium groove (10) can increase as required, and eccentric jaw (6) lower left side half-nut ring can be made in the lower right side as required.
Jia Te garden shape material or part; As long as change centering three-jaw (1) commonly used, rotate any one clamping cone tooth (3), incense coil chain wheel (2) rotates, drive centering three-jaw (1) is felt relieved clamping.
Irregular parts in addition such as the folder spy is eccentric or square: pull down centering three-jaw (1), install eccentric jaw (6), rotate three eccentric clamping screws (7) respectively, can carry out off-centre and the clamping of irregular part in addition.For balance in addition part, when folder is special eccentric orfice press from both sides a side on the other hand to monodactyle, can carry out certain balance to other part.
The present invention is simple and practical, scientific arrangement, widely saved the time and change chuck labour intensity, improved the centering precision of lathe and three-jaw chuck, accomplish to put things right once and for all, except that using the part of lathe floral disc processing, accomplish that the eccentric and irregular part in addition of car no longer changes chuck, the machined into that is through with is changed the history of chuck.
Claims (3)
1. multipurpose three-jaw chuck is characterized in that: it has three centering jaws (1), be existing three-jaw, it matches and is installed in three the branch grooves such as grade (10) all around of garden shape collet body (5) top, the incense coil chain wheel (2) that its underpart has tooth and its to be placed in the garden shape collet body (5) matches, this incense coil chain wheel (2) is with existing identical, its underpart has the awl tooth to be distributed in collet body (5) three clamping cone teeth (3) all around with its underpart five equilibrium and to match, clamping cone tooth (3) intersects uniform with five equilibrium groove (10), the garden shape gland (4) of bottom is pushed down incense coil chain wheel (2), it is moved down, three bottoms, left side of waiting branch groove (10), an eccentric clamping screw (7) that is microscler I-shaped shape respectively is housed, eccentric jaw (6) also is installed in three five equilibrium grooves (10), and three screws (9) are distributed in the top of collet body (5).
2. it is waited to levy and is by the multipurpose three-jaw chuck of claim 1: its cam finger (6) top is identical with four paws commonly used, but the bottom does not have the half-nut ring, and the eccentric clamping screw (7) in there is the half-nut ring in left side, its underpart and is installed in three branch grooves such as grade (10) matches a breach (11) on the folder spy portion millable of eccentric jaw (6).
3. the multipurpose three-jaw chuck by claim 1 is characterized in that: five equilibrium groove (10) can increase as required, and eccentric jaw (6) lower left side half-nut ring can be made in the lower right side as required.
