Description
Technical field
It the utility model is related to field of fixtures, more particularly to cylinder sleeve clamp.
Background technology
Cylinder jacket is the kernel component of engine work, except bearing high temperature, high pressure in the work of fuel engines
Adverse circumstances outside, also act as centering, be oriented to effect.Therefore for the dimensional accuracy, behavior precision, surface quality of cylinder jacket
Propose very high requirement.But due to the influence of different capacity, purposes etc., cause cylinder jacket cylinder diameter, length, size,
There is very big difference in structure design etc., very big puzzlement is brought to manufacturer.
Utility model content
The purpose of this utility model is to provide a kind of clamp force distribution uniform and applied widely cylinder sleeve clamp.
To achieve the above object, the technical solution adopted in the utility model is：Cylinder jacket bipyramid ringfeder magic chuck, including
Slide the pull bar being arranged, body and swelling device successively from the inside to the outside, body is located at provided with slip cap between adjacent swelling device
On sliding sleeve, swelling device includes two taper sheaths being symmetrical set and the ringfeder that is arranged between two taper sheaths, cone
On body, the taper surface of two taper sheaths is oppositely arranged and remains with spacing between two taper sheaths shape set slip cap, rises
Set both ends are provided with the inclined-plane corresponding with the taper surface of taper sheath, and ringfeder is circumferentially uniformly distributed along body, are glued between adjacent ringfeder
Vulcanization rubber is connected with, body left part is provided with the boss that diameter is more than taper sheath internal diameter, and pull bar right part is provided with diameter and is more than cone
Shape covers the block plate of internal diameter, and spacing is remained between block plate and body right side, and pull bar drives swelling device to block plate during left movement
Two taper sheaths do relative motion.
It is provided between the taper sheath and body along the axially extending flat key of body.
The outer body face is provided with radially extension and respectively holding screw corresponding with each swelling device, tightly
Screw is determined between adjacent ringfeder.
The quantity of the swelling device is two.
Each swelling device includes 12 ringfeders.
This fixture is stepped up using wide-angle combined type bipyramid ringfeder, and clamp force distribution is uniform, and blessing scope is big, and ringfeder uses
Alloy tool steel matrix adds the combination of vulcanization rubber, can step up workpiece in very large range, and whole fixture is cheap, adds
Work precision is high, and switching is convenient, easy to use, can realize being switched fast in the range of certain cylinder diameter.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
As depicted in figs. 1 and 2, cylinder jacket bipyramid ringfeder magic chuck, including slide the pull bar being arranged successively from the inside to the outside
1st, body 2 and swelling device, sliding sleeve 3 of the slip cap on body 2 is provided between adjacent swelling device, and swelling device includes two
The individual taper sheath 4 being symmetrical set and the ringfeder 5 being arranged between two taper sheaths 4, the slip cap of taper sheath 4 are located at body 2
On, the taper surface of two taper sheaths 4 is oppositely arranged and spacing is remained between two taper sheaths 4, and the both ends of ringfeder 5 are provided with and taper
The corresponding inclined-plane of taper surface of set 4, ringfeder 5 are uniformly distributed along body 2 is circumferential, between adjacent ringfeder 5 adhesion have vulcanization rubber
6, the left part of body 2 is provided with the boss 7 that diameter is more than the internal diameter of taper sheath 4, and the right part of pull bar 1 is provided with diameter and is more than in taper sheath 4
The block plate 8 in footpath, remains with spacing between block plate 8 and the right side of body 2, pull bar 1 drives swelling device to block plate during left movement 8
Two taper sheaths 4 do relative motion.
It is provided between taper sheath 4 and body 2 along the axially extending flat key 9 of body 2, prevents phase between taper sheath 4 and body 2
Mutually rotate.
The lateral surface of body 2 is provided with radially extension and respectively holding screw 10 corresponding with each swelling device, tightly
Screw 10 is determined between adjacent ringfeder 5, prevents from mutually rotating between ringfeder 5 and taper sheath 4.
The quantity of swelling device is two.Each swelling device includes 12 ringfeders 5, makes the uniform force of workpiece 11.
First the terminal pad of the left end of body 2 and lathe is connected during use, and added with cylindrical centering, the left end of pull bar 1 with lathe
Locking oil cylinder is connected by screw thread, and workpiece 11 is set on ringfeder 5, with the positioning knife bar axially position installed on knife tower, then
Stepping up oil cylinder using lathe drives pull bar 1 to drive two taper sheaths 4 in swelling device to do relative motion to left movement, block plate 8,
Two taper sheaths 4 are mutually drawn close, and so as to extrude radial outward movement of the ringfeder 5 along body 2, are held out against workpiece 11 by ringfeder 5
Fixed, after 11 completion of processing of workpiece, pull bar 1 moves right, and ringfeder 5 resets in the presence of rubber 6 is vulcanized, and releases to workpiece
11 fixation.
The excircle of workpiece of present apparatus processing can reach 0.02mm to the axiality of endoporus；Jump of each processing end face to endoporus
Momentum can reach 0.01mm；Workpiece diameter excursion is accommodated in the case where stepping up oil cylinder stroke as 20mm and can reach a 10mm left sides
It is right.
