Description
Technical field
The invention belongs to the clamp for machining of a kind of part, be specifically related to a kind of thin wall cylinder class part end face clamp for machining.
Background technology
At present, the turning clamp of thin-walled tube kind part, main employing manual type clamping and automatic expansion core clamp two kinds.Manually
Formula clamping device, its shortcoming is that operator's labor intensity is big, and labor productivity is low；Automatically expansion core fixture, installs more complicated, maintenance
The difficulty changed is bigger.
And, current expansion core clamping structure, from structure and use, there is also many problems.Due to processed thin wall cylinder
Class part comparison is long, and in order to ensure that thin-walled tube kind part steps up, expansion core also to lengthen accordingly, and the expansion core after lengthening is in the course of processing
In be easy to generation and tremble, thus cause the percent defective of processed thin-walled tube kind part to improve.Expansion core clamping structure material of main part
Higher than processed thin wall cylinder class part material hardness, frequently result in processed thin wall cylinder class part deformation and gouge workpiece.
Summary of the invention
The present invention solves that problem that prior art exists proposes, its objective is to provide a kind of thin wall cylinder class part end face
Clamp for machining.
The technical scheme is that a kind of thin wall cylinder class part end face clamp for machining, including base plate, base plate passes through at the end
Plate taper bolt, bottom plate screw are fixed with parallel support seat, support side, seat upper surface and are articulated and connected ring, and opposite side is provided with pin
Axle, is connected ring and is connected with the sidewall of gland by gland taper bolt, gland screw, be cased with eyelet bolt, eyelet bolt outside bearing pin
On locking nut be pressed to gland support on seat, support seat, solid respectively by screw in groove that gland binding end is formed
Surely having lower positioning sleeve, upper positioning sleeve, lower positioning sleeve, upper positioning sleeve combine composition continuous print tubular positioning sleeve.
Support seat side-walls and be fixed with, by limited block screw, the limited block that cross section is L-shaped.
The parallel positioning sleeve up and down of the present invention completes the radial direction location of thin-walled tube kind part, by supporting determining of seat side-walls
Position block completes thin wall cylinder class part axial location, and clamping is easy to operate, efficiency is high, it is to avoid workpiece to be processed in the course of processing
Tremble, reduce percent defective, the convenient dismounting of the present invention, it is simple to safeguard and change.

Detailed description of the invention
Hereinafter, referring to the drawings and embodiment the present invention is described in detail:
As shown in Figure 1, 2, a kind of thin wall cylinder class part end face clamp for machining, including base plate 1, by base plate circle on base plate 1
Taper pin 2, bottom plate screw 3 are fixed with parallel support seat 4, support side, seat 4 upper surface and are articulated and connected ring 14, and opposite side is provided with
Bearing pin 5, is connected ring 14 and is connected with the sidewall of gland 10 by gland taper bolt 12, gland screw 13, be cased with movable joint spiral shell outside bearing pin 5
Bolt 6, gland 10 is pressed to support on seat 4 by the locking nut 7 on eyelet bolt 6, and support seat 4, gland 10 binding end are formed
Being respectively fixed with lower positioning sleeve 17, upper positioning sleeve 8 by screw 9 in groove, lower positioning sleeve 17, upper positioning sleeve 8 combine composition even
Continuous tubular positioning sleeve.
Support seat 4 side-walls and be fixed with the L-shaped limited block in cross section 15 by limited block screw 16.Limited block 15 can be right
The part to be processed 18 inserted in lower positioning sleeve 17 carries out axial limiting, stops axial in the course of processing of part 18 to be processed
Mobile.
Being provided with handle 11 at described gland 10 outer wall, handle 11 person convenient to operate hold.
Described support seat 4, groove that gland 10 binding end is formed is formed screwed hole respectively, lower positioning sleeve 17, upper fixed
Forming counter sink in position set 8, lower positioning sleeve 17 is fixed in support seat 4 by screw 9 through above-mentioned counter sink, by upper positioning sleeve 8
It is fixed in gland 10.
Base plate 1 is connected with the mobile pallet of lathe by bolt, the axis of described lower positioning sleeve 17 and the main shaft of lathe
Axis collinear, described support seat 4, the material of gland 10 are No. 45 steel, and upper positioning sleeve 8, the material of lower positioning sleeve 17 are H62,
Upper positioning sleeve 8, lower positioning sleeve 17 material softer than the material of part 18 to be processed, it is to avoid the gouge in cargo handling process.
During use, base plate 1 is fixed on the mobile pallet of lathe, it is ensured that lower positioning sleeve 17 is coaxial with the main shaft of lathe,
Being inserted in lower positioning sleeve 17 by part 18 to be processed, its end face withstands on limited block 15 side-walls, tightens locking nut 7, gland
10 drive upper positioning sleeve 8 to compress part 18 to be processed, thus complete part 18 clamping to be processed.
The parallel positioning sleeve up and down of the present invention completes the radial direction location of thin-walled tube kind part, by supporting determining of seat side-walls
Position block completes thin wall cylinder class part axial location, and clamping is easy to operate, efficiency is high, it is to avoid workpiece to be processed in the course of processing
Tremble, reduce percent defective, the convenient dismounting of the present invention, it is simple to safeguard and change.
