Abstract

The invention discloses a thin-walled cylindrical part end face machining fixture which comprises a bottom plate. Parallel supporting seats are fixed onto the bottom plate through bottom plate taper pins and bottom plate screws, a connecting ring is hinged to one side of the upper end face of each supporting seat, a pin is arranged on the other side of the upper end face of each supporting seat, each connecting ring is connected with the side wall of a pressing cover through a pressing cover taper pin and a pressing cover screw, hinged bolts sleeve the pins, the pressing covers are pressed on the supporting seats through locking nuts on the hinged bolts, and a lower positioning sleeve and an upper positioning sleeve are fixed into grooves formed by the supporting seats and the pressing covers through screws respectively and combined to form a continuous cylindrical positioning sleeve. A thin-walled cylindrical part is radially positioned by the upper positioning sleeve and the lower positioning sleeve which are parallel, the thin-walled cylindrical part is axially positioned by positioning blocks on the side walls of the supporting seats, the thin-walled cylindrical part end face machining fixture is convenient in clamping operation, high in efficiency and convenient to detach, maintain and replace, shaking of a workpiece to be machined in the machining process is avoided, and rejection rate is reduced.

Description

Thin wall cylinder class part end face clamp for machining
Technical field
The invention belongs to a kind of clamp for machining 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 hand clamping and the automatic expansion core of adopting clamps two kinds.Hand clamping device, its shortcoming is that operator's labour intensity is large, and labor productivity is low; Automatic expansion core fixture, install more complicated, the difficulty of maintain and replace is larger.
And, also there is many problems in current expansion core clamping structure from structure and use.Because processed thin wall cylinder class part comparison is long, in order to ensure that thin-walled tube kind part steps up, expansion core also wants corresponding lengthening, and the expansion core after lengthening is easy to generation and trembles in process, thus causes the percent defective of processed thin-walled tube kind part to improve.Expansion core clamping structure material of main part is higher than processed thin wall cylinder class part material hardness, often causes processed thin wall cylinder class part deformation and gouge workpiece.
Summary of the invention
The present invention proposes for solving prior art Problems existing, its objective is and provides a kind of thin wall cylinder class part end face clamp for machining.
Technical scheme of the present invention is: a kind of thin wall cylinder class part end face clamp for machining, comprise base plate, by base plate taper bolt on base plate, bottom plate screw is fixed with parallel supporting seat, side, supporting seat upper surface is articulated and connected ring, opposite side is provided with bearing pin, connecting ring is by gland taper bolt, gland screw is connected with the sidewall of gland, bearing pin overcoat has eyelet bolt, gland is pressed on supporting seat by the locking nut on eyelet bolt, supporting seat, lower positioning sleeve is fixed with respectively by screw in the groove that gland binding end is formed, upper positioning sleeve, lower positioning sleeve, upper positioning sleeve combines composition continuous print tubular positioning sleeve.
Supporting seat side-walls is fixed with the L-shaped limited block in cross section by limited block screw.
The parallel positioning sleeve up and down of the present invention completes the radial location of thin-walled tube kind part, thin wall cylinder class part axial location is completed by the locating piece of supporting seat side-walls, clamping is easy to operate, efficiency is high, avoid trembling of workpiece to be processed in process, reduce percent defective, the present invention is for convenience detach, is convenient to safeguard change.

Detailed description of the invention
Below, with reference to drawings and Examples, the present invention is described in detail:
As Fig. 1, shown in 2, a kind of thin wall cylinder class part end face clamp for machining, comprise base plate 1, by base plate taper bolt 2 on base plate 1, bottom plate screw 3 is fixed with parallel supporting seat 4, side, supporting seat 4 upper surface is articulated and connected ring 14, opposite side is provided with bearing pin 5, connecting ring 14 is by gland taper bolt 12, gland screw 13 is connected with the sidewall of gland 10, bearing pin 5 overcoat has eyelet bolt 6, gland 10 is pressed on supporting seat 4 by the locking nut 7 on eyelet bolt 6, supporting seat 4, lower positioning sleeve 17 is fixed with respectively by screw 9 in the groove that gland 10 binding end is formed, upper positioning sleeve 8, lower positioning sleeve 17, upper positioning sleeve 8 combines composition continuous print tubular positioning sleeve.
Supporting seat 4 side-walls is fixed with the L-shaped limited block in cross section 15 by limited block screw 16.Limited block 15 can carry out axial limiting to the part to be processed 18 inserted in lower positioning sleeve 17, stops part 18 to be processed moving axially in process.
Described gland 10 outer wall place is provided with handle 11, and handle 11 convenient operation person hold.
Screwed hole is formed respectively in the groove that described supporting seat 4, gland 10 binding end are formed, counter sink is formed in lower positioning sleeve 17, upper positioning sleeve 8, lower positioning sleeve 17 is fixed in supporting seat 4 through above-mentioned counter sink by screw 9, is fixed in gland 10 by upper positioning sleeve 8.
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 axis conllinear of lathe, described supporting seat 4, the material of gland 10 are No. 45 steel, the material of upper positioning sleeve 8, lower positioning sleeve 17 is H62, the material of upper positioning sleeve 8, lower positioning sleeve 17 is softer than the material of part 18 to be processed, avoids the gouge in cargo handling process.
During use, base plate 1 is fixed on the mobile pallet of lathe, ensure that lower positioning sleeve 17 is coaxial with the main shaft of lathe, part 18 to be processed is inserted in lower positioning sleeve 17, its end face withstands on limited block 15 side-walls, tighten locking nut 7, gland 10 drives upper positioning sleeve 8 to compress part 18 to be processed, thus completes part 18 clamping to be processed.
The parallel positioning sleeve up and down of the present invention completes the radial location of thin-walled tube kind part, thin wall cylinder class part axial location is completed by the locating piece of supporting seat side-walls, clamping is easy to operate, efficiency is high, avoid trembling of workpiece to be processed in process, reduce percent defective, the present invention is for convenience detach, is convenient to safeguard change.
