Abstract
The utility model discloses a drill jig on a pump body large end face. The drill jig comprises a drill jig plate arranged on the pump body large end face and a cushion block arranged on a pump body small end face. The drill jig plate is round, a locating block is arranged on the lower side of the drill jig plate and is round, the outer diameter of the drill jig plate is larger than that of the locating block, and the drill jig plate and the locating block have the same center of circle. The drill jig plate is provided with a plurality of drill sleeve holes evenly distributed and a locating hole, drill sleeves are arranged in the drill sleeve holes, the locating hole is close to the edge of the drill jig plate, a locating pin is arranged in the locating hole, the locating pin is connected to the drill jig plate, and the lower end of the locating pin protrudes out of the lower side of the drill jig plate. In use, the pump body is arranged on the cushion block, then the locating block of the drill jig plate is inserted in a through hole in the pump body large end face, so that the drill jig plate is located on the pump body in the axial direction, the lower end of the locating pin is made to abut against one side of a protruding block on the pump body large end face, the drill jig plate can be located on the pump body in the circumferential direction, and drilling can begin. Line marking and sample punching are not needed, and work efficiency and position precision of holes are improved.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of pump housing drill jig.
Background technology
The pump housing is the strength member in water pump, and the pump housing one side has a large end face, and opposite side has a small end face, and large end face is connected with pump cover, for the pump housing is connected with pump cover, need on large end face, process some connecting holes.If small lot batch manufacture, general employing line is rushed sample and is then placed on drilling machine and holes, if produce in enormous quantities, if also adopt this method boring, have following problem, the one, it is very time-consuming that sample is rushed in line, operating efficiency is very low, and labor strength is large, and the 2nd, it is low that the hole site precision that sample bores is rushed in line, in the time of can making the pump housing be connected with pump cover, cause interference, affect properties of product.
Utility model content
Problem to be solved in the utility model is, for the defect of prior art, provides the drill jig on a kind of pump housing large end face, 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.Drill jig on a kind of pump housing large end face, comprise and be arranged on the bushing plate on pump housing large end face and be arranged on the cushion block on pump housing small end face, described bushing plate is circular, the downside of bushing plate is provided with locating piece, locating piece is circular, the external diameter of bushing plate is greater than the external diameter of locating piece, the same center of circle of bushing plate and locating piece, bushing plate is provided with some uniform drill bushing holes and a locating hole, drill bushing is provided with drill bushing in hole, and locating hole, near bushing plate edge, is provided with an alignment pin in locating hole, alignment pin is connected on bushing plate, and the downside of bushing plate is protruded in the lower end of alignment pin.During use, first the pump housing is placed on cushion block, then the locating piece of bushing plate is inserted in the through hole on pump housing large end face, make bushing plate axial location on the pump housing, make again the lower end of alignment pin lean against projection one side of pump housing large end face, make bushing plate circumferential location on the pump housing, can start boring.Need not rule and rush sample, improve the positional precision in operating efficiency and hole.
As preferably, the center of described bushing plate is provided with a lightening hole.Alleviate the weight of bushing plate, handled easily.
Main beneficial effect of the present utility model is, can increase work efficiency, and reduces labor strength, improves the positional precision in hole, improves the quality of products.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of 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, drill jig on a kind of pump housing large end face, comprise the bushing plate 2 being arranged on pump housing large end face and be arranged on the cushion block 4 on pump housing small end face, described bushing plate is circular, the downside of bushing plate is provided with a positioning block 22, locating piece is circular, the external diameter of bushing plate is greater than the external diameter of locating piece, the same center of circle of bushing plate and locating piece, bushing plate is provided with 6 uniform drill bushing holes 24 and a locating hole 21, in drill bushing hole, be provided with drill bushing 3, locating hole is near bushing plate edge, in locating hole, be provided with an alignment pin 1, alignment pin is connected on bushing plate, the downside of bushing plate is protruded in the lower end of alignment pin.The center of described bushing plate is provided with a lightening hole 23.During use, first the pump housing 5 is placed on cushion block, cushion block upper side is provided with the boss 41 of a circle, boss is inserted in the through hole of pump housing small end face, then the locating piece of bushing plate is inserted in the through hole on pump housing large end face, makes bushing plate axial location on the pump housing, then make the lower end of alignment pin lean against a side of the projection 6 of pump housing large end face, bushing plate is circumferentially located on the pump housing, can start boring.Need not rule and rush sample, improve the positional precision in operating efficiency and hole.
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.
