Description
Technical field
The utility model belongs to machining equipment technical field, particularly relates to a kind of gear pump case outer face secondary process frock.
Background technology
As depicted in figs. 1 and 2, gear pump case workpiece comprises the housing 1 with inner chamber 2, and housing 1 is provided with upper flange 3 and lower flange 4, the equal and centerline collineation of both internal diameter.In actual processing, first that housing 1 and upper flange 3, lower flange 4 integrally casting is shaping, then fine finishining is carried out in the outer face of the work in-process heart to the end face of flange and housing 1.Irregular due to the shape of gear pump workpiece, the operating desk being difficult to the work in-process heart is fixed, and this is that the outer face processing of gear pump case 1 brings difficulty.
Utility model content
The utility model provides that a kind of structure is simple, simple operation, fixes and positions effective gear pump case outer face secondary process frock for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: gear pump case outer face secondary process frock comprises flat columniform fixed disk, is provided with screwed hole at the center of fixed disk; Also comprise the mandrel that two ends are equipped with threaded rod, wherein the threaded rod of one end is positioned at the screwed hole at fixed disk center, the threaded rod of the other end is provided with pressing plate and locknut, and the external diameter of mandrel equals the upper flange of housing and the internal diameter of lower flange; Also comprise be set in outside mandrel, fixed cover that sidewall is provided with lateral direction penetrating screwed hole, in the screwed hole of fixed cover, be provided with trip bolt; The disk body of fixed disk is also provided with multiple pin-and-hole, in each pin-and-hole, is equipped with pin, the top of pin is positioned at connecting hole on lower flange and the external diameter of pin equals the internal diameter of connecting hole; Each pin is all arranged with cushion block, and each cushion block is contour.
Advantage of the present utility model and good effect are: the utility model provides a kind of frock for the processing of equipment gear pump case outer face of structural design advantages of simple, mandrel is located in upper flange and lower flange, its top of each pin being arranged with cushion block all penetrates in the connecting hole on lower flange, the lower end of mandrel is socketed by fixed cover and fastening by trip bolt after the inner chamber of housing docks with the inner of lower flange, pressing plate is made to be pressed on the end face of upper flange by the locknut screwed on threaded upper ends bar, achieve the fixing of gear pump case workpiece, simple operation, fix and position effective.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model using state;
Fig. 2 is the main TV structure schematic diagram of the utility model using state.
In figure: 1, housing; 2, inner chamber; 3, upper flange; 4, lower flange; 5, threaded rod; 6, locknut; 7, fixed cover; 8, mandrel; 9, trip bolt; 10, fixed disk; 11, pressing plate; 12, pin; 13, cushion block.
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 and Fig. 2, the utility model comprises flat columniform fixed disk 10, is provided with screwed hole at the center of fixed disk 10.Fixed disk 10 is for being connected with the chuck of machining center.
Also comprise the mandrel 8 that two ends are equipped with threaded rod 5, wherein the threaded rod 5 of one end is positioned at the screwed hole at fixed disk 10 center, the threaded rod 5 of the other end is provided with pressing plate 11 and locknut 6, and the external diameter of mandrel 8 equals the upper flange 3 of housing 1 and the internal diameter both lower flange 4.For upper flange 3 and the lower flange 4 of different inner diameters, the mandrel 8 of various outer diameter can be matched.
Also comprise be set in outside mandrel 8, fixed cover 7 that sidewall is provided with lateral direction penetrating screwed hole, in the screwed hole of fixed cover 7, be provided with trip bolt 9.
The disk body of fixed disk 10 is also provided with multiple pin-and-hole, is equipped with pin 12 in each pin-and-hole, the top of pin 12 is positioned at connecting hole on lower flange 4 and the external diameter of pin 12 equals the internal diameter of connecting hole.
Each pin 12 is all arranged with cushion block 13, and each cushion block 13 is contour.
Using method: mandrel 8 and fixed disk 10 are assembled, afterwards by gear pump case trade union college on mandrel 8, its top of each pin 12 being arranged with cushion block 13 all penetrates in the connecting hole on lower flange 4, and the lower end of mandrel 8 is socketed by fixed cover 7 after the inner chamber of housing 1 docks with the inner of lower flange 4 and inwardly turn trip bolt 9 carries out fastening.The locknut 6 screwed afterwards on threaded upper ends bar 5 makes pressing plate 11 be pressed on the end face of upper flange 3, achieves the fixing of gear pump case workpiece.This frock can be installed on the rotating disk of machining center by fixed disk 10 together with workpiece afterwards.
