Abstract
The utility model discloses a pump cover drilling jig which comprises a drilling jig plate arranged on the upper side of a pump cover. The drilling jig plate comprises an oval plate, and a circle of a flange is arranged on the edge of the lower side of the oval plate. The inner side of the flange and the lower side face of the oval plate form a groove, and two drill bushing holes are formed in the oval plate of the drilling jig plate. The centers of the drill bushing holes are distributed on the long-axis center line of the oval plate. Drill bushings are arranged in the drill bushing holes in a transition fit mode. Two through holes I are further formed in the oval plate of the drilling jig plate, and the centers of the two through holes are also distributed on the long-axis center line of the oval plate. The two through holes are located in the two sides of the drill bushing holes respectively. A bottom plate is arranged on the lower side of the pump cover, and T-shaped bolts are used for connecting the bottom plate, the pump cover and the drilling jig plate. The drilling jig reduces labor intensity of a worker, and improves working efficiency, position precision of holes and product quality.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of pump cover drill jig.
Background technology
Pump cover is part conventional in pump series products, for pump cover is connected with other part, need on pump cover, process two holes.When small lot batch manufacture, frequent first center-punching on part is then holed on drilling machine, but when producing in enormous quantities, center-punching is wasted time and energy, and operating efficiency is low, and labor strength is large, and the positional precision that center-punching is holed is low, affects product quality.
Utility model content
Problem to be solved in the utility model is, for the defect of prior art, provides a kind of pump cover drill jig, can increase work efficiency, and reduces labor strength, improves the positional precision in hole, improves the quality of products.
The purpose of this utility model is achieved through the following technical solutions.A kind of pump cover drill jig, comprise the bushing plate that is arranged on pump cover upside, described bushing plate comprises a Long Circle plate, the edge of Long Circle plate downside is provided with a circle flange, the downside of the inner side of flange and Long Circle plate forms a groove, the Long Circle plate of bushing plate is provided with two drill bushing holes, the central distribution in drill bushing hole is on Long Circle plate major axis center line, drill bushing is provided with drill bushing in hole, drill bushing and drill bushing hole interference fits, on the Long Circle plate of bushing plate, be also provided with two through hole I, the center of two through holes is also distributed on Long Circle plate major axis center line, two through holes lay respectively at the both sides in drill bushing hole, the downside of pump cover is provided with a base plate, the downside of base plate is provided with two blind holes, the bottom of blind hole is provided with through hole II, tommyhead bolt is through the blind hole of base plate, through hole II, the through hole I of pump cover and bushing plate, the large end of tommyhead bolt is positioned at blind hole, the small end of tommyhead bolt is provided with nut.The upper side of pump cover is Long Circle structure, and the groove part of bushing plate is inserted in to pump cover, and bushing plate locates on pump cover, on bushing plate, the position of drill bushing is exactly the position of holing on pump cover, do not need center-punching to hole, reduced labor strength, improved operating efficiency.And the positional precision of drill bushing hole and drill bushing is high on bushing plate, the positional precision of holing is also high, has improved product quality.
Main beneficial effect of the present utility model is, improved operating efficiency, reduced labor strength, improved the positional precision in hole, improved product quality.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model bushing plate.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
As shown in Figure 1 to Figure 2, pump cover drill jig, comprise the bushing plate 1 that is arranged on pump cover upside, described bushing plate comprises a Long Circle plate, the edge of Long Circle plate downside is provided with a circle flange 5, the downside of the inner side of flange and Long Circle plate forms a groove, the Long Circle plate of bushing plate is provided with two drill bushing holes 9, the central distribution in drill bushing hole is on Long Circle plate major axis center line, in drill bushing hole, be provided with drill bushing 3, drill bushing and drill bushing hole interference fits, on the Long Circle plate of bushing plate, be also provided with two through hole I 8, the center of two through holes is also distributed on Long Circle plate major axis center line, two through holes lay respectively at the both sides in drill bushing hole, the downside of pump cover is provided with a base plate 6, the downside of base plate is provided with two blind holes 7, the bottom of blind hole is provided with through hole II, tommyhead bolt 2 is through the blind hole of base plate, through hole II, the through hole I of existing through hole and bushing plate on pump cover, the large end of tommyhead bolt is positioned at blind hole, the small end of tommyhead bolt is provided with spiral shell 4.Because the aperture of holing on pump cover is greater than φ 10, so process on upright drill.Operating procedure is as follows: 1. down, groove is inserted in pump cover upside to bushing plate groove part, and bushing plate is located on pump cover; 2. the through hole I through existing through hole and bushing plate on the blind hole of base plate, through hole II, pump cover by tommyhead bolt, the large end of tommyhead bolt is positioned at blind hole, at the small end of tommyhead bolt, the upside nut screwing clamping of bushing plate; 3. the above-mentioned part assembling and drill jig are placed on workbench, start drilling machine, and drill bit is aimed at drill bushing boring; 4. unclamp nut, bushing plate is taken off from pump cover, process next part.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
