Abstract
The utility model provides a kind of lathe hydraulic expansion sleeve clamp, including lathe spindle, main shaft tail is equipped with angling cylinder, pull rod is equipped on the piston rod of angling cylinder, terminal pad is equipped on main shaft, equipped with opening expansion set in the hole of the terminal pad, opening expansion set internal taper hole is interior to be equipped with expansion core, and expansion core is fixedly connected by lock washer and backing-up screw with pull rod；Preferably, the opening expansion set is equipped with multiple open slots.The utility model positioning accuracy is high, and workpiece deformation is small, and coaxiality error is small between outer circle, endoporus and location hole that this process is processed, is become apparent from for thin-walled parts effect.
Description
Technical field
The utility model belongs to machinery field, relates in particular to a kind of lathe hydraulic expansion sleeve clamp.
Background technology
Some machine components are needed when carrying out turnery processing with endoporus Set and Positioning, originally using common scroll chuck with
Hydraulic pressure scroll chuck supports endoporus, and positioning accuracy is low, be easy to cause the outer circle of the endoporus and the processing of this process, the concentricity of endoporus is missed
Poor big, scroll chuck support endoporus be easy to cause workpiece deformation, influences bigger particularly with thin-walled parts.
The content of the invention
The utility model provides a kind of lathe hydraulic expansion sleeve clamp, and it is low, coaxial to solve positioning accuracy in background technology
Spend the shortcomings that error is big.
What the technical solution of the utility model was realized in：A kind of lathe hydraulic expansion sleeve clamp, it is main including lathe spindle
Axis afterbody is equipped with angling cylinder, and pull rod is equipped on the piston rod of angling cylinder, terminal pad, the hole of the terminal pad are equipped on main shaft
It is interior to be equipped with opening expansion set, expansion core is equipped in opening expansion set internal taper hole, expansion core is fixed by lock washer and backing-up screw with pull rod
Connection；
Preferably, the opening expansion set is equipped with multiple open slots.
The beneficial effects of the utility model are：The utility model positioning accuracy is high, and workpiece deformation is small, outside the processing of this process
Coaxiality error is small between circle, endoporus and location hole, is become apparent from for thin-walled parts effect.
Description of the drawings
Fig. 1 is the diagrammatic cross-section of the utility model；
Fig. 2 is the A-A of the utility model Fig. 1 to diagrammatic cross-section.
Part explanation：1st, angling cylinder, 2, main shaft, 3, terminal pad, 4, opening expansion set, 5, expansion core, 6, workpiece, 7, pull rod,
8th, lock washer, 9, backing-up screw, 10, open slot.
Specific embodiment
For a better understanding and implementation, the utility model is further described below in conjunction with the accompanying drawings：A kind of lathe liquid
Press expansion sleeve clamp, by angling cylinder 1 mounted in 2 afterbody of lathe spindle, pull rod 7 is screwed on 1 piston rod of angling cylinder, terminal pad 3 with
The endoporus that opening expansion set 4 coordinates reserves allowance, and terminal pad 3 is mounted on main shaft 2, is then put down from the vehicle endoporus and bottom hole
Face, then by opening expansion set 4 in 3 hole of terminal pad, expansion core 5 is put into opening 4 internal taper hole of expansion set, and on pull rod 7, use
Lock washer 8 is fixed with backing-up screw 9.
Corresponding hydraulic system and electric control system are mixed, fixture installment work just completes.
The course of work：
Before work starts, 1 piston rod of angling cylinder is in stretching state, by workpiece 6 on opening expansion set 4, passes through behaviour
Making switch makes 1 piston rod of angling cylinder retract, and pull rod 7, expansion core 5 is driven to be moved to the left, 5 male cone (strobilus masculinus) stretching opening expansion set 4 of expansion core
Internal taper hole, opening 4 outer circle of expansion set swells, so as to clamp workpiece.After machining, by Operation switch angling cylinder 1 is made to live
Stopper rod stretches out, and pull rod 7, expansion core 5 is driven to move right, and 5 male cone (strobilus masculinus) of expansion core is disengaged with 4 internal taper hole of opening expansion set, and opening is swollen
It covers 4 outer circles to reduce automatically, so as to unclamp workpiece, workpiece 6 can be removed at this time.
Using the fixture, workpiece deforms small, high precision machining, easy to operate, and production efficiency is high.
