Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 2, a kind of for processing the fixture of gear pump body bottom surface, the pump housing includes the datum level 1 being oppositely arranged
And bottom surface, the side of datum level 1 are connected with flange 10, fixture includes bottom plate 11, is vertically installed with the first limit on bottom plate 11
Position column 12, the second limited post 13, pedestal 16 and screw rod 18, the first limited post 12 and the second limited post 13 are disposed as at least one
It is a, it is equipped on pedestal 16 and adjusts bolt 17,17 in the shape of " pin " points of bolt of the first limited post 12, the second limited post 13 and adjusting
Cloth, screw rod 18 are set as several, and the middle part sliding sleeve of screw rod 18 is equipped with briquetting 21, and the top matching of screw rod 18 is arranged with compression
Nut 19.
When processing bottom surface, rotatably compressing nut 19 first moves up it along screw rod 18, and briquetting 21 is unclamped, and
Briquetting 21 is rotated to the outside of triangle disposition；Rotation adjusts bolt 17 later, keeps it mobile to the outside of triangle disposition；Then will
The pump housing is put into fixture, and specifically datum level 1 is down-set, and flange 10 is made to be located at the inside of triangle disposition；Then adjust
The position for saving the pump housing, makes the side of flange 10 be adjacent to the second limited post 13；Then it rotates backward and adjusts bolt 17, make it to " product "
The medial movement of font adjusts bolt 17 in moving process and pushes the pump housing to the direction of the first limited post 12, until making flange
10 are adjacent to the first limited post 12, and the first limited post 12, the second limited post 13 and adjusting bolt 17 will be pumped from three directions at this time
Body clamps；Briquetting 21 is finally rotated, is pressed in briquetting 21 on flange 10, and screw clamp nut 19, briquetting 21 is pressed on
On flange 10, the fixation to the pump housing can be completed, bottom surface is upward after fixing.
The pump housing is fixed in flange 10 that the utility model is had by means of pump housing itself, and structure is simple, operation side
Just, and the first limited post 12 and the second limited post 13 can be used as reference point, can use ginseng when processing bottom surface
Examination point quickly positions, to improve machining accuracy.
Further, the first limited post 12 and the second limited post 13 are disposed as two, between two the first limited posts 12
Line and two the second limited posts 13 between line be mutually perpendicular to, adjust bolt 17 axis and two the first limited posts 12
Between line be mutually perpendicular to.Two the first limited posts 12 and two the second limited posts 13 can with the structural strength of lifting clamp,
Ensure the stability after the pump housing fixes.In the utility model others embodiment, the first limited post 12 and the second limit
Position column 13 may be set to be three or more.
Further, several backing plates 14, the height of the first limited post 12 and the second limit are further fixedly arranged on bottom plate 11
The height of position column 13 is all larger than the thickness of backing plate 14.After the pump housing fixes, flange 10 is arranged on backing plate 14, and by first
Limited post 12 and the limit of the second limited post 13.
Further, the fixed form of backing plate 14 are as follows: backing plate 14 is set as rectangular slab, opens up that there are two heavy on backing plate 14
Hole, two counterbores are distributed along the length direction of backing plate 14, and backing plate 14 is fixedly connected by two fastening bolts 15 with bottom plate 11, and two
The head of a fastening bolt 15 is arranged in correspondingly in two counterbores.The mode being fixed by bolts, backing plate 14 and bottom plate
Can be in close contact between 11, thus guarantee the pump housing in being put into fixture after bottom surface levelness, be conducive to improve processing essence
Degree.
Further, the lower part of screw rod 18 also fixing sleeve is equipped with cushion block 22, the thickness of the thickness of cushion block 22 and backing plate 14 it
Difference is less than the thickness of flange 10.Cushion block 22 is used to limit the minimum point of briquetting 21, and briquetting 21 is made to be consistently higher than backing plate 14, with convenient
Briquetting 21 is adjusted, while cushion block 22 can be higher than after also ensuring flange 10 on being put into backing plate 14, to guarantee
Briquetting 21 can compress flange 10.
Further, backing plate 14 is set as four, and screw rod 18 is set as four, and four screw rods 18 are arranged in correspondingly
The side of four backing plates 14, and screw rod 18 is located at the outside of triangle disposition.
Further, washer 20 is additionally provided between briquetting 21 and clamp nut 19.Washer 20 can be set to spring pad
Circle improves the stability of the pump housing to prevent clamp nut 19 from loosening.
Further, the height of pedestal 16 is greater than the height of the first limited post 12 and the height of the second limited post 13, and
The axis of bolt 17 is adjusted not less than the upper end of the first limited post 12 and the upper end of the second limited post 13.Because of the thickness of flange 10
It is limited, bolt 17 is adjusted if just needing very close bottom plate 11 on flange 10 to be against, and causes to be difficult to rotate, so will
It adjusts bolt 17 and is arranged higher, after the pump housing clamps, adjust bolt 17 and be against on the pump housing on flange 10, have enough
Space is rotated to bolt 17 is adjusted.
