Description
Technical field
The invention belongs to B23Q3/06：The technical field of Workpiece clamping device.
Background technology
Fixture is widely used in the processing and manufacturing of workpiece.The plain grinding processing of shaft-like workpiece is the basis of following process, its
Processing of the machining accuracy on subsequent workpiece affects larger, therefore, the plain grinding processing to shaft-like workpiece has certain required precision.
At present, axle class milling clamper often has the following disadvantages：Fixture clamping part is unadjustable, therefore a fixture can only clamp one
The workpiece of specific dimensions is planted, fixture utilization rate is low, it is limited to use, and centered on the fixture used when processing to valve at present is more
Frame, it is impossible to enough that valve is processed by the part that centre frame is clamped.
Patent announcement number discloses a kind of adjustable valve processing of fixture for the Chinese invention patent of CN103506705A
Device, being driven by pneumatic means makes the distance between first support and second support adjust, and before valve is clamped, makes the
Between one support and second support, distance is increased, and after valve to be processed is placed, is adjusted between first support and second support
Distance, by jamming of valve.In such scheme, the distance between first support and second support can be adjusted, so as to adjust
Between support along valve axial direction distance, therefore the valve of different length can be processed, but it is different to adapt to diameter
Valve.
When a section to valve is carried out washing and cuts processing, valve one end is fixed by chuck, and valve can be rotated, in valve
In process, washed the section diameter cut and diminished, chuck can cause to be washed to the pawl clamp force of valve end to be cut section and produce torsion,
Even result in valve breakage.
The content of the invention
The invention is intended to provide a kind of engine valve fixture, valve is carried out washing cut processing when, to solve existing gas
Door fixture can cause by wash cut section produce torsion problem.
Base case：Engine valve fixture in this programme, including base, are connected with some first on the base
Hydraulic pressure support bar, the first hydraulic pressure support bar upper end are connected with support block, and the support block upper surface is provided with several balls,
Described base one end is connected with the first guide rail perpendicular to base, is slidably connected and is parallel to the flat of base on first guide rail
Weighing apparatus device, the bascule include flat board and pressure apparatus, and the pressure apparatus is detachably connected on above flat board, described flat
Plate bottom surface is provided with flexible layer, and liquid is housed in the pressure apparatus, and the base is connected with second away from one end of the first guide rail
Hydraulic pressure support bar, the second hydraulic pressure support bar upper end are rotatably connected to chuck, and the chuck side is connected with rotating shaft.
The operation principle of above-mentioned technical proposal and have the beneficial effect that：Bascule is slided up and down first, adjusts bascule
The distance between with base, valve is positioned over above support block along the direction parallel with base, bascule is then adjusted
Position makes the contacts baseplate valve in bascule, adjusts the height of the second hydraulic pressure support bar, makes chuck be directed at valve retainer, by gas
Valve chuck clamping, rotating shaft are connected the output end of motor by door chuck, are started motor, are rotated motor-driven rotatable shaft, so as to band
Take offence and to rotate, valve cantilever is longer and one end is clamped by chuck, the other end of valve is free end, it may occur that rotated,
When to valve, one section is processed, cutter carries out washing to same section when cutting back and forth, and the processed section of valve can produce torsion.
Some first hydraulic pressure support bars are provided with below valve, and the upper end of the first hydraulic pressure support bar is respectively connected with
Support block, for supporting valve, anti-air-stop gate is hanging and torsion is produced in rotation process, and the ball in support block can be by gas
Linear contact lay between door and support block is changed into a contact, reduces frictional force when valve is rotated, meanwhile, arrange in the top of valve
Bascule, bascule include flat board and pressure apparatus, and the bottom surface of flat board is flexible layer, cuts processing carrying out washing to valve
When, when occurring gap between valve and flat board, flexible layer can expand and fill up gap, and flexible layer can be according to washing bevel
Washing the degree of being whittled into carries out self-control, it is ensured that to valve and the contact surface gapless of flat board, and pressure dress is provided with above flat board
Put, liquid be housed in pressure apparatus, liquid has mobility, can pressurizer be uniform to the pressure that valve applies
, the balance of valve is further kept, especially has support and bascule above and below the processed section of valve, no
The valve that only can adapt to different-diameter is processed, and anti-air-stop gate produces movement, and is prevented from being processed section generation torsion
Power, improves stability when valve is processed, meanwhile, the use of centre frame compared with prior art, is reduced, can be whole to valve
Any part of section is processed, and improves the applicability of this fixture.
Prioritization scheme one, used as the further optimization to base case, the base is provided with the second guide rail, and described first
Hydraulic pressure support bar and the second hydraulic pressure support bar are slidably connected on the second guide rail.Second guide rail can make the first hydraulic pressure support bar
Can horizontally slip with the second hydraulic pressure support bar such that it is able to adapt to the valve of different length, further improve the suitable of this fixture
The property used.
Prioritization scheme two, used as the further optimization to prioritization scheme one, the support block is disc, and the ball is equal
It is even to be distributed in support block.Discoidal support block does not have corner angle, in transportation, easily arranges out with other objects, prevents
Damaged in collision object is produced with other objects, ball is evenly distributed in support block, can further adapt to the gas of different-diameter
Door.
Prioritization scheme three, as the further optimization to prioritization scheme two, also including flow tube, adjacent first hydraulic pressure support bar
Between by flow tube connect, valve is equipped with flow tube.Connected by flow tube between first hydraulic pressure support bar, Neng Goubao
The hydraulic pressure demonstrate,proved between the first hydraulic pressure support bar is equal, so that the first hydraulic pressure support bar is impartial to the pressure of valve, passes through
Change the state of valve, the pressure in an other first hydraulic pressure support bar can be adjusted.
Prioritization scheme four, used as the further optimization to prioritization scheme three, the liquid is hydraulic oil.Hydraulic oil has anti-
Corrode and antiwear property, heat endurance and oxidation stability are good, strong applicability.
Prioritization scheme five, used as the further optimization to prioritization scheme four, the flexible layer is soft made by alloy material
Property layer.Alloy material has certain toughness and anti-pressure ability is stronger, and the degree that alloy material can be processed according to valve is entered
Row adjust automatically, further prevents occurring gap between base plate and valve.
