Description
Technical field
The utility model relates to wheel manufactures, more particularly to a kind of fixture wheel.
Background technique
The process for machining of wheel usually requires to process by three sequences, the positions such as front face of wheel, wheel rim and centre bore
Processing is usually completed in two sequences, but due to the difference of various sizes of wheel external diameter parameter, the limited stroke range of chuck is led
Cause is difficult to process various sizes of wheel hub with a sleeve clamp, during actual processing, whenever needing replacing different dimensions
When wheel, the even a whole set of fixture of replacement set of parts is required, Workshop Production non-cutting time is increased, reduces production efficiency,
Increase the labor intensity of worker.If a set of automation fixture for adapting to a variety of different specification size wheels can be developed, by pole
Big improving production efficiency.
In addition, the maximum grip power that can provide of fixture can be with stepping up for revolving speed and some loses, design
Suitable centrifugal force compensation mechanism can guarantee mach safe and reliable.
Summary of the invention
The purpose of this utility model is to provide a kind of fixture wheel.
A kind of fixture wheel, including clamping jaw, positioning tie bar A, balance weight shell, guide shaft A, Deflector block, balance weight, pedestal,
Pin, positioning tie bar B, guard ring, airtight pedestal, airtight mandril, airtight supporting block, guide shaft B, airtight cover, pressing plate；Pin A, spiral shell
Follow closely A, screw B, collet body, stretching screw, screw C, O-ring A, screw D, slot coiled hair positioning screw, O-ring B, O-ring C,
Screw E, main shaft, screw F, spring, turret head head bleed screw A, turret head head bleed screw B, screw G, screw H, spiral shell
Follow closely I.
Pedestal is connected by screw E with main shaft, and collet body is fixed on the base by screw C, and stretching screw is by collet
Body is connected with main shaft, and O-ring A is pressed at the gap of collet body and pedestal by guard ring, seals, and with screw F
It tightens.The lower surface of six groups of positioning tie bar B is engaged with the toothed surfaces of collet body, and is tightened with two screw B, positioning tie bar A
It is connected and fixed by two pins with positioning tie bar B, clamping jaw is connected and fixed by two screw A and two pin A and is drawn in positioning
On bar A, balance weight shell is connected and fixed by screw G with pedestal, and guide shaft A passes through the through-hole above balance weight shell, and wears
The both ends of overshoot block, balance weight shell limit guide shaft A axial movement by screw, and balance weight is mounted on balance weight interior of shell
Groove, two guide shaft B pass through the through-hole on balance weight, and are deep into the bottom outlet of balance weight shell, and guide shaft B passes through two six
Angle head head bleed screw A is tightened on the corresponding threaded hole of balance weight shell, limits the axial movement of two guide shaft B.Spring
It is arranged in the bottom outlet on balance weight, turret head head bleed screw B is tightened on the corresponding threaded hole of balance weight shell, limitation
The axial movement of spring, at the both ends of positioning tie bar A, there are two pressing plates, pressing plate to be connected and fixed by one group of screw H flat for installation
It weighs on block shell, limits positioning tie bar A in this way in the movement of main shaft axial direction, it is uniform in base upper surface circumferencial direction
Three groups of tight mechanisms are distributed with, airtight pedestal is connected and fixed on pedestal by one group of screw I, and O-ring C is mounted on airtight pedestal
In lower recess, airtight mandril is mounted in the circular hole on airtight pedestal, and limits gas using two fluting coiled hair positioning screws
The rotation of close mandril, O-ring B are mounted between airtight pedestal and airtight mandril, and airtight supporting block is connected and fixed by screw D
Airtight mandril upper surface, airtight cover are sealed the gas circuit of chassis interior by an one group of screw I and O-ring C.
In actual use, main shaft drives the positioning tie bar B on collet body radially to stretch out and receive by stretching screw
Contracting, a certain position of the clamping jaw in the stroke range stretched out and shunk, wheel is by fixture positioning and clamping, and airtight supporting block is by vehicle
Wheel pressure, and flushed with the supporting plane of clamping jaw, airtight mandril compresses O-ring B at this time, and air is prevented to examine position from this gas
Outflow, lathe detection system detect preset air pressure value, wheel correct placement are indicated, if wheel is in fixture
Upper correct without placing, lathe will be by the pressure feedback warning note that detects.The Qi Jian mechanism of the utility model passes through
The airtight supporting block of two kinds of different structures is installed and using two groups of gas circuits of Internal and external cycle on pedestal, is adapted to the vehicle of 8 kinds of sizes
Wheel.The centrifugal force compensation mechanism of the utility model at work, effect of the balance weight by centrifugal force under high revolving speed, along guide shaft
The centrifugal force of itself is transmitted on positioning tie bar A by the direction of B by Deflector block, offset a part of clamping jaw, positioning tie bar A and
The centrifugal force that positioning tie bar B is generated, can make fixture that enough chucking powers, spring can still be maintained in high revolving speed in this way
Elasticity make the balance weight moment keep be in contact with Deflector block, without due to do not have axial constraint generate shake.
The clamping jaw uses high-strength aluminum alloy.
The balance weight shell, guide shaft A, Deflector block uses CrMo material, for resisting the effect of higher centrifugal force.
The fixture is adapted to sizes wheel by adjusting position of the stairstepping clamping jaw on positioning tie bar A,
Each position is adapted to two kinds of sizes, and mobile four positions may finally adapt to the wheel of sizes.
Two fluting coiled hair positioning screws are in use, keep fluting direction horizontal, are pressed into using flexible steel wire
It in slot and tightens, plays the role of loosening.
Two turret head head bleed screw A and a turret head head bleed screw B are in use, retaining hole
Direction it is consistent, flexible steel wire is passed through into turret head head bleed screw and is tightened, serves and loosens.
The Deflector block outer surface uses low-speed WEDM processing method, to guarantee its surface roughness.
The base lower surface is disposed with several loss of weight nests.
Since abrasion leads to difference in height after the positioning tie bar long-time use, so the utility model draws positioning
Bar is designed as two parts: positioning tie bar A and positioning tie bar B, convenient for the adjustment in fixture height gap.
Between the balance weight shell and pedestal in addition to screw attachment, also fluted and pin guarantees the accurate of position
Positioning.
The balance weight is limited in fixed height by guide shaft B so that the upper and lower surface of balance weight and balance weight shell and
It there are enough gaps between pedestal, avoids interfering, influences fixture operation smoothness.
Relative to the fixture wheel of existing market, the utility model clamp structure is simple, and reliable performance, weight drops significantly
It is low, and it is adapted to the wheel of sizes, there is bigger processing flexibility.
