Description

High-pressure gear pump shell flange end face secondary process frock
Technical field
The utility model belongs to mechanical equipment technical field, particularly relates to a kind of high-pressure gear pump shell flange end face secondary process frock.
Background technology
As shown in Figure 1, the main body of high-pressure gear pump generally comprises shell workpiece 4 and at least two flanges 10 be positioned on shell workpiece 4, aforementioned body is generally obtained by the one-body molded processing of casting technique, and the work in-process heart completes the fine finishining of each several part afterwards, as the fine finishining etc. of flange 10 end face.Irregular due to the shape of shell workpiece 4, fixing on the operating platform being difficult to the direct work in-process heart, this is that the processing of flange 10 end face brings difficulty.
Utility model content
The utility model for solve in known technology the technical problem that exists and provide that a kind of structure is simple, simple operation, auxiliary good fixing effect high-pressure gear pump shell flange end face secondary process frock.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: high-pressure gear pump shell flange end face secondary process frock comprises the base that longitudinal section is L shape, be provided with two screwed hole groups at the top of base, each screwed hole group comprises the independent screwed hole of two two of becoming inside and outside next-door neighbour to arrange; Also comprise the first support bar and the second support bar that two ends are equipped with external thread part, both bottoms lay respectively at be distributed in outside two screwed holes in and adopt nut-locking, be equipped with locknut at the external thread part of the first support bar and the second support bar upper end; Also comprise head rod and the second connecting rod that two ends are equipped with external thread part, both bottoms lay respectively at be distributed in inner side two screwed holes in and adopt nut-locking, the external thread part of head rod upper end is provided with locknut, the first pressing plate and locknut from top to bottom successively, the external thread part of the second connecting rod upper end is provided with locknut, the second pressing plate and locknut from top to bottom successively, and the outer end of each pressing plate is pressed on the locknut of the support bar top outside it respectively.
Advantage of the present utility model and good effect are: the utility model provides a kind of frock for the processing of additional high pressure gear pump case end face of flange of structural design advantages of simple, shell workpiece is placed on base, between two groups of hold down gags, by regulating the vertical height of the locknut below the vertical height of the first support bar and the second support bar upper end locknut and head rod and the second connecting rod upper end, regulate the height of the first pressing plate and the second pressing plate, make both suitable with the pressure contact portion height at shell workpiece top, by the locknut of turn head rod and the second connecting rod upper end, first pressing plate and the crimping of the second pressing plate are fixed on the top of shell workpiece, complete the fixing of shell workpiece.Simple operation, good fixing effect.The operating platform that the base of L tee section structure is convenient to the work in-process heart is fixed.
Accompanying drawing explanation
Fig. 1 is using state structural representation of the present utility model.
In figure: 1, base; 2, locknut; 3, shell workpiece; 4, the first support bar; 5, head rod; 6, the first pressing plate; 7, the second pressing plate; 8, the second support bar; 9, the second connecting rod; 10, flange.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises the base 1 that longitudinal section is L shape, is provided with two screwed hole groups at the top of base 1, and each screwed hole group comprises the independent screwed hole of two two of becoming inside and outside next-door neighbour to arrange.
Also comprise the first support bar 4 and the second support bar 8 that two ends are equipped with external thread part, both bottoms lay respectively at be distributed in outside two screwed holes in and adopt locknut 2 to lock, be equipped with locknut 2 at the external thread part of both the first support bar 4 and the second support bar 8 upper end.Herein, the external thread part of each post upper also can't help to pass in locknut 2, regulates its position in upper external screw thread portion, regulate the vertical height of the upper surface of the locknut 2 as supporting surface by turn locknut 2.
Also comprise head rod 5 and the second connecting rod 9 that two ends are equipped with external thread part, both bottoms lay respectively at be distributed in inner side two screwed holes in and adopt locknut 2 to lock.The external thread part of head rod 5 upper end is provided with locknut 2, first pressing plate 6 and locknut 2 from top to bottom successively, the external thread part of the second connecting rod 9 upper end is provided with locknut 2, second pressing plate 7 and locknut 2 from top to bottom successively, and the outer end of each pressing plate is pressed on the locknut 2 of the support bar top outside it respectively.
Using method: shell workpiece 3 is placed on base 1, between two groups of hold down gags.By regulating the vertical height of the locknut 2 below both the vertical height of both the first support bar 4 and the second support bar 8 upper end locknut 2 and head rod 5 and the second connecting rod 9 upper end, regulate the height of the first pressing plate 6 and the second pressing plate 7, make both suitable with the pressure contact portion height at shell workpiece 3 top, by the locknut 1 of both turn head rod 5 and the second connecting rod 9 upper end, first pressing plate 6 and the crimping of the second pressing plate 7 are fixed on the top of shell workpiece 3, complete the fixing of shell workpiece 3.Now, flange 10 is positioned at the sidepiece of shell workpiece 3.Afterwards whole frock is fixed on the operating desk of machining center by base 1 together with workpiece.
