Abstract
The utility model provides a locating assisting device for a three-jaw hollow hydraulic chuck of a numerically controlled lathe. The locating assisting device comprises an adjusting location barrel, a location adjusting screw and a locking nut. The adjusting location barrel is formed through connection of a first barrel body and a second barrel body which are combined into a whole through one-step molding. The inner diameter of the first barrel body is greater than the inner diameter of the second barrel body; the rear end of the first barrel body is integrally connected with an annular bench which is provided with three screw holes; one installation screw is screwed in each screw hole; the locking nut is fixed in the second barrel body; the location adjusting screw is in screw-thread fit and connection with the locking nut; and the front end of the location adjusting screw passes through a bolt hole in the front end wall of the second barrel body. The locating assisting device is simple in structure, facilitates adjustment, is adaptive to the locating and processing of workpieces of different lengths and sizes without replacing or turning of jaws, reduces rejection rate of the workpieces caused by location error of loosening and clamping of the jaws of the chuck, and is reusable after one-off installation.
Description
Technical field
The utility model belongs to the servicing unit of lathe special mould clamp, relates in particular to the auxiliary locator of numerically controlled lathe three-jaw hollow oild chuck.Adopt this device, former claw stationary positioned mode is changed into the adjustable flexible positioning of existing location cartridge type, effectively improved alignment quality and operating efficiency.
Background technology
Numerically controlled lathe adopts claw chucking+stationary positioned integral type location usually with the locate mode of three-jaw hollow oild chuck, uses general.This kind locate mode exists claw to unclamp, locating surface is out of shape thereupon when tightening; Or Workpiece length size and profile change; Therefore all must adjust perhaps turning claw again; Thereby the chucking and the locating surface that cause frequent turning claw have promptly increased auxiliary adjustment workload, also exist simultaneously because the chuck clearance issues; Do not have during chucking card just or workpiece and reasons such as the claw locating surface does not contact fully cause the Workpiece length dimensional discrepancy of processing, workpiece reprocessed products or waste product increase.
The utility model content
The purpose of the utility model provides a kind of servicing unit of numerically controlled lathe three-jaw mesopore oild chuck, and known claw stationary positioned mode is become the adjustable flexible positioning of location cartridge type, has improved alignment quality and operating efficiency.
The technical scheme that adopts is:
A kind of numerically controlled lathe three-jaw hollow oild chuck positioning auxiliary device comprises adjustment positioning tube, location adjustment screw and locking nut, it is characterized in that:
The adjustment positioning tube is the two-step cylindrical shell, is is promptly connected and composed by first cylindrical shell and second cylindrical shell, and is one-time formed overall structure, and the internal diameter of first cylindrical shell is greater than the internal diameter of second cylindrical shell; First cylinder back-end is connected with the ring platform, on the ring platform, offers three screw holes, in each screw hole, is installed with the installation screw; Locking nut is fixed in second cylindrical shell, and location adjustment screw is connected with the locking nut threaded engagement, and location adjustment screw front end passes the second barrel front end wall upper bolt hole.
The assembling process of the utility model is:
To adjust the through hole that positioning tube is installed to automatic three-jaw hollow chuck earlier, and be fastened on the automatic three-jaw hollow chuck body through 3 M6 screws and to fix.On location adjustment screw, locking nut is installed; Then according to the length adjustment location adjustment screw of workpiece and the distance of clamp nut; The assembly of clamp nut of adjusting and location adjustment screw is installed in the adjustment positioning tube that fixes fasteningly with the inner hexagon spanner of 12mm, workpiece being installed can begin to process at last again.The length dimension of workpiece can be adjusted through location adjustment screw.
The main technical principle of the utility model is: on the scroll chuck of original lathe standard configuration, the chuck positioning auxiliary device that utilizes the boring installation of inner via hole position is by adjustable positioning tube, adjustment screw, fixed screw, compositions such as locking nut.After the installation, positioning function only is provided, gripping part is still realized by former chuck jaws, thereby has been guaranteed that chucking separates with localization part, the phase mutually noninterfere.Because of claw be rise at any time, the part of card and turning, and this device is fixed, so, guarantee that it fixedly is the starting point of the utility model that locating surface can be adjusted with locating surface.
The utility model has solved existing chuck location technology defective effectively; Location cartridge type frock through after improving is installed on the chuck of equipment standard configuration; Make it when workpiece is installed; Gripping part separates with locating surface, does not produce to influence each other, thereby is unlikely to because defectives such as former integral type chuck gap or locating surface distortion cause the product orientation error.And this device has realized that adjustable positions is whole, can finely tune the location according to Different products length, and is convenient and swift, accurate and effective.
That the beneficial effect of the utility model is is not only simple in structure, the adjustment is convenient; And can need not change or the situation of turning claw under just can adapt to the location processing of different length dimension workpiece; And reduced because the workpiece waste product that chuck jaws rises, the fastening bit error causes; Also having once mounting can reusable characteristic, is applicable to workpiece processing in batches.Reduce the non-cutting time of loaded down with trivial details replacing claw and turning claw, farthest improved production efficiency and product quality.

The specific embodiment
A kind of numerically controlled lathe three-jaw hollow oild chuck positioning auxiliary device comprises adjustment positioning tube 1, location adjustment screw 2 and locking nut 3, it is characterized in that:
The assembling process of the utility model is:
To adjust the through hole that positioning tube 1 is installed to automatic three-jaw hollow chuck 10 earlier, and be fastened on the automatic three-jaw hollow chuck body through 3 M6 screws 8 and to fix.On location adjustment screw 2, locking nut 3 is installed; Then according to the length adjustment location adjustment screw of workpiece and the distance of clamp nut; The assembly of clamp nut of adjusting and location adjustment screw is installed in the adjustment positioning tube that fixes fasteningly with the inner hexagon spanner of 12mm, workpiece 11 being installed can begin to process at last again.The length dimension of workpiece can be adjusted through location adjustment screw.
