Abstract
The utility model discloses a three-jaw self-centering chuck that can be widely used to process special-shaped workpieces in large batches in the field of machining technology and resolves the defects of the prior art, including long auxiliary time, low processing efficiency and high labor intensity in the course of processing special-shaped workpieces, which mean that the prior art is not suitable for batch processing. The three-jaw self-centering chuck includes three linked clamping jaws, a special-shaped workpiece-clamping clamp is firmly arranged on the clamping jaws and is divided into three parts which are respectively fixed on the three clamping jaws, and when the three parts are closed, the clamping hole of the special-shaped workpiece-clamping clamp matches the clamped surface of the processed special-shaped workpiece. When being used, the clamp can be automatically positioned and calibrated according to the shape of a special-shaped workpiece, thus greatly shortening the auxiliary time of processing, reducing the accumulated error of clamping and improving the precision of processing, and moreover, according to the different shapes of special-shaped workpieces, clamp cores with different specifications can be used.
Description
Technical field
The utility model relates to the Machining Technology field, particularly relates to a kind of three-jaw self-centering chuck of the clamping device with processing profiled workpiece.
Background technology
The processing method of special-shaped workpiece has three kinds usually, and a kind of is to use the chuck clamping workpiece on engine lathe, uses dial gauge that workpiece is carried out the single-piece centering then, processes at last again.Another kind method is directly to carry out the clamping special-shaped workpiece with the three-jaw self-centering chuck on the lathe, adopts and carries out centering in the method for claw position pad pad, processes then.Also having a kind of is to adopt floral disc to process, and uses floral disc to carry out clamping processing for the workpiece of shape more complicated more.
Adopt the processing profiled workpiece of chuck clamping, must be when clamping according to each claw on the shape adjustments chuck of workpiece, workpiece is fixed on the chuck, carry out centering with dial gauge, measurement situation according to dial gauge is adjusted claw, last clamping is firm, thereby reaches the purpose of centering.But in process, after a procedure of a workpiece machined, the same procedure of processing next workpiece also needed clamping again, carries out centering with dial gauge, causes working (machining) efficiency low.Directly carry out the clamping special-shaped workpiece, workpiece is fixed on back use dial gauge centering on the chuck,, carry out centering in the method for claw position pad pad so can only measure situation according to dial gauge because of claw is synchronous operation with three-jaw self-centering chuck.This can cause the machining accuracy of workpiece not high, and this method can only be processed simple special-shaped workpiece.Use floral disc to process, the workpiece of general more complicated just can use the floral disc clamping workpiece, and the clamping centering mode and the chuck of workpiece are basic identical, but because workpiece is complicated, so the time of clamping centering can be long.Make that the efficient that adopts floral disc to process is equally very low.
Above several method, when processing profiled workpiece non-cutting time long, working (machining) efficiency is low, labour intensity is big, is not suitable for batch machining.
The utility model content
Technical problem to be solved in the utility model provides a kind of three-jaw self-centering chuck that is used for large batch of special-shaped workpiece processing.
The technical scheme that its technical problem that solves the utility model adopts is: three-jaw self-centering chuck, the claw that comprises three interlocks, on claw, be set with special-shaped workpiece clamping anchor clamps, special-shaped workpiece clamping anchor clamps are divided into three parts, this three part is separately fixed on three claws, when this three part is closed, the clamping hole of special-shaped workpiece clamping anchor clamps with the clamping face of processing profiled workpiece suitable.
Described special-shaped workpiece clamping anchor clamps comprise anchor clamps overcoat and anchor clamps core, and the anchor clamps overcoat is installed on the claw, and the anchor clamps core is installed in anchor clamps and puts outward, and are provided with the clamping hole.
Described anchor clamps overcoat is a circular ring type, and is provided with anchor clamps core installed surface.
Described anchor clamps core is a circular ring type, and ring core is the clamping hole.
Described anchor clamps overcoat connects by connecting bolt with claw, and the anchor clamps core connects by connecting bolt with the anchor clamps overcoat.
The beneficial effects of the utility model are, use this device to add and do not need to carry out the clamping centering man-hour, can locate centering automatically according to the shape of special-shaped workpiece, shortened the non-cutting time that adds man-hour greatly, cumulative errors when having reduced clamping have improved machining accuracy, can be widely used in the processing of large batch of special-shaped workpiece, and, can use the anchor clamps core of different size according to difform special-shaped workpiece.
