Description
Technical field
The invention belongs to milling apparatus technical field, more particularly to a kind of guiding valve grinding clamp for disk grinder with
And the clamping method of guiding valve.
Background technology
Guiding valve is a core component of the main type truck air control valve of brake 120 of current railway freight-car, main to rise
To the effect for sealing and connecting gas circuit.Need to be ground the working face of guiding valve with disk grinder in process.
As shown in figure 1, the process of existing disk grinder grinding guiding valve is：Grinder starts, and abrasive disk rotation drives folder
Guiding valve in tool and fixture makees spinning motion around itself center of circle, and relative operating, abrasive disk are formed between guiding valve and abrasive disk
In abrasive material start to guiding valve working face carry out micro cutting, be ground processing.
As shown in Fig. 2 existing guiding valve grinding clamp is the problem of being primarily present：1st, fixture 11 and guiding valve 2 simultaneously with grinding
Disk 4 is contacted, and abrasive disk is also ground while being ground to guiding valve to fixture, increases the loss of abrasive disk；2nd, guiding valve 2 with
Without clamping between fixture 11, be gap coordinate, during fixture rotation, guiding valve can in fixture play, easily there is arrisdefect
Phenomenon, influences grinding quality；3rd, guiding valve is without counterweight, and required pressure is only guiding valve deadweight during grinding, due to guiding valve lighter in weight,
Only 0.25 ㎏, it is smaller to the pressure of abrasive disk, cause grinding efficiency relatively low.
The content of the invention
It is an object of the invention to：For above-mentioned problem fixture and abrasive disk can be prevented effectively from there is provided one kind
Contact, play of the guiding valve during fixture rotation is eliminated, while the disk grinder that is used for of grinding efficiency can also be improved
The clamping method of guiding valve grinding clamp and guiding valve.
The technical proposal of the invention is realized in this way：A kind of guiding valve grinding clamp for disk grinder, its feature
It is：Including guiding valve clamping disk, multiple clamping cavitys for clamping guiding valve, institute are provided with the guiding valve clamping disk
Guiding valve is stated to be placed in correspondence clamping cavity and together with by hold-down mechanism, guiding valve is fixed with guiding valve clamping disk, it is multiple
Guiding valve clamping forms an overall structure after guiding valve clamping disk, and the face to be ground of the multiple guiding valve is in same level
On, the guiding valve grinding clamp that clamping has multiple guiding valves is positioned on the abrasive disk of disk grinder, the guiding valve it is to be ground
Face contacts with abrasive disk and there is gap between the guiding valve clamping disk and abrasive disk.
Guiding valve grinding clamp of the present invention for disk grinder, its described hold-down mechanism includes briquetting and oblique
Block, the briquetting side is plane and contacted with the one side of guiding valve that the another side of the guiding valve is resisted against guiding valve clamping circle
The clamping cavity inner wall of disk, the opposite side of the briquetting coordinates for guiding valve to be clamped in into corresponding clamping chamber for inclined-plane and with skewback
In vivo.
Guiding valve grinding clamp of the present invention for disk grinder, its multiple guiding valve is with guiding valve clamping disk
Axle center centered on be evenly distributed on same circumference.
A kind of guiding valve clamping method of use guiding valve grinding clamp, it is characterised in that：Comprise the following steps：

b）, multiple guiding valves are put into the corresponding clamping cavity of guiding valve clamping disk, the face to be ground of the multiple guiding valve
And base contacts；
c）, respectively briquetting is placed in clamping cavity, and make the plane side and the cunning in corresponding clamping cavity of briquetting
Valve is contacted, and then skewback is put into clamping cavity again, and skewback is contacted with the inclined-plane side cooperation of briquetting；
d）, rap the skewback downwards, promote briquetting to compress guiding valve, the guiding valve clamping disk, guiding valve, briquetting and skewback
Collectively form an overall structure；
e）, the guiding valve clamping disk for being provided with guiding valve is placed on the abrasive disk of disk grinder, now guiding valve is treated
Abradant surface is contacted with abrasive disk, and there is gap between guiding valve clamping disk lower surface and abrasive disk, and start machine starts to grind
Mill；After end to be ground, rapping skewback exits it, you can take out the guiding valve after grinding.
Guiding valve clamping method of the present invention, it is in the step a）In, the spacer pin is multidiameter structure, and its is small
Hold as helicitic texture and be screwed on base, for the radial positioning of guiding valve clamping disk, the supporting pin connects with base for screw thread
Binding structure, makes the strong point of at least three supporting pins in same level by rotating supporting pin and is formed and guiding valve clamping is justified
The supporting surface of disk, the vertical direction for guiding valve clamping disk is positioned.
The beneficial effects of the invention are as follows：
1st, the present invention, by the structure design of supporting pin, makes the guiding valve after clamping exist in clamping process is carried out to guiding valve
During grinding, the guiding valve clamping disk for clamping guiding valve is not contacted with abrasive disk, so as to reduce grinding clamp to abrasive disk
Abrasion.
2nd, the present invention carries out clamping using slanting wedge clamping way to guiding valve, and simple to operate, reliable clamping is effectively eliminated
Play of the guiding valve during fixture rotation, stable workpiece grinding quality.
3rd, guiding valve to be ground and fixture one overall structure of formation after being assembled in the present invention, cleverly by the weight of fixture
Guiding valve formation counterweight is passed to, is conducive to lifting grinding efficiency.
4th, the present invention, by the structure design of base, makes multiple guiding valves after clamping in clamping process is carried out to guiding valve
Face to be ground is in same reference plane, can ensure that abrasive disk can be ground to each guiding valve, and its amount of grinding is minimum.
5th, in the present invention supporting pin and base threaded connection design, can not only adjust height, allow guiding valve clamping disk
All the time it is in the same plane, and after base basal plane is worn away, can be removed, the convenient finishing for carrying out reference plane.
6th, circle designs are taken by multiple guiding valves arrangement of clamping in the present invention, in process of lapping, each sliding valve movement
Track is consistent, and grinding quality uniformity is high.
