Description

Rotary lathe anchor clamps

Technical field

The present invention relates to a kind of rotary lathe anchor clamps.

Background technology

In general production and processing, process the coaxial not isometrical hole of a plurality of stageds mainly with machining center and these two kinds of processing mode processing of boring now.The boring process velocity is slow, efficient is low, and the Cutter Body Processing with Machining Center cost is higher, influences economic benefit; Most of processing is all changed in the turning processing for this reason.Because the clamping mode (three-jaw, four paws) of lathe can not satisfy the clamping of the irregular workpiece of profile, usually can use frock clamp.Existing frock clamp is guaranteeing under the prerequisite that processing can be carried out smoothly, mainly with repeated removal clamping and frock axial displacement dual mode clamping workpiece.Repeated removal clamping advantage is processing each staged coaxial not isometrical hole dimension precision height, and weak point is that the repeated removal clamping makes location benchmark, precision inconsistent, and dimensional accuracy is low between the Kong Yukong, self size disparity is big, causes the whole workpiece quality to descend; The advantage of frock axial displacement is a clamping, location benchmark, precision unanimity, shortcoming is that workpiece centre-of gravity shift main shaft gyration centre distance is far away after the displacement, prevent that centrifugal force is excessive in the process, need to reduce the lathe rotating speed, influence machined surface roughness, also reduced operating efficiency, make troubles for automated production in enormous quantities.

Summary of the invention

The purpose of this invention is to provide a kind of location benchmark, precision unanimity, can promote the rotary lathe anchor clamps of whole workpiece dimensional accuracy.

The technical scheme that the present invention adopts for achieving the above object is: a kind of rotary lathe anchor clamps, comprise telophragma (1), terminal pad (2), flap (3), pressing plate one (4), block one (5), location-plate one (6), location-plate two (7), connecting axle (8), locating piece (9), pressing plate two (10), block two (11) and motherboard (12), described telophragma (1) is fixedlyed connected with terminal pad (2), terminal pad (2) is fixed on the lathe spindle, flap (3) is arranged on the indentation, there of motherboard (12) and is connected on the telophragma (1), the big end of connecting axle (8) is arranged in the telophragma hole, small end is connected with flap, motherboard (12) oppositely is fastened on the telophragma (1), block one (5), location-plate one (6), location-plate two (7), locating piece (9) and pressing plate two (10) are fixed on the flap (3), and block one (5) and pressing plate two (10) are fixed on the motherboard (12).

Described telophragma (1) is fixed on the terminal pad (2) by 4 interior hexagonal cylindrical bolts.

Described flap (3) passes flap (3) arc groove by 2 interior hexagonal cylindrical bolts and is connected on the telophragma (1).

Described motherboard (12) oppositely is fastened on the telophragma (1) by 4 interior hexagonal cylindrical bolts.

A kind of rotary lathe anchor clamps of the present invention, it is the special fixture of the workpiece that dimensional accuracy is high between a plurality of eccentric orfices of machined into and the Kong Yukong, chuck apparatus with manual mode control, compact conformation, simple, mounting or dismounting are convenient, guarantee that a clamping just can satisfy the high workpiece of dimensional accuracy between two eccentric orfices of processing and the Kong Yukong, and location benchmark, precision unanimity, eliminate the centrifugal forces affect that the processing eccentric orfice causes, promote the whole workpiece dimensional accuracy, increase work efficiency convenient batch process the in batches.
