Abstract
The utility model discloses a drilling jig on the end face of an ear bulge of a machine base. The drilling jig comprises a drilling jig plate arranged on the machine base, wherein the drilling jig plate is uniformly provided with a plurality of drilling sleeves, the lower side of the drilling jig plate is provided with a cylindrical positioning ring, the edge of the drilling jig plate is provided with a positioning ear bulge which is a triangle, one side of the triangle coincides with the edge of the drilling jig plate, one angle of the triangle, facing towards the outer side of the edge, is a rounded angle, and one drilling sleeve is positioned in the positioning ear bulge. The drilling jig is high in drilling precision and high in working efficiency.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of drill jig.
Background technology
Support is a kind of part on water pump, and the end face of support is provided with through hole, through through hole, with bolt and nut, support is connected with adjacent part, and the processing of through hole is to bore and be processed to form on drilling machine.If support is 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, the one, it is very time-consuming that sample is rushed in line, and operating efficiency is very low, the 2nd, it is low that the hole site precision that sample bores is rushed in line, poor product quality.
Utility model content
Problem to be solved in the utility model is, for the defect of prior art, provides a kind of support ear to climb the drill jig on end face, and borehole accuracy is high, and operating efficiency is high.
The purpose of this utility model is achieved through the following technical solutions.A kind of support ear is climbed the drill jig on end face, comprise the bushing plate being arranged on support, on bushing plate, be evenly equipped with some drill bushings, the downside of bushing plate is provided with centring ring cylindraceous, and the edge of bushing plate is provided with a chucking lug and climbs, and chucking lug is climbed as triangle, the coincident of leg-of-mutton one side and bushing plate, a leg-of-mutton angle is a fillet towards Wai，Gai angle, edge, and a drill bushing is positioned at chucking lug and climbs.As shown in Fig. 4, on the edge of support end face, there are 6 ears to climb, ear is climbed up the through hole that internal diameter is less than φ 10, and there is datum hole at the center of support end face, during use, support is placed on bench drill, centring ring on bushing plate is inserted to datum hole and carry out axial location, make chucking lug on bushing plate climb to climb to overlap with the ear of support end face and circumferentially locate, startup drilling machine switch, a hand is lived bushing plate, can hole.Described drill bushing is provided with fastening screw, has bored after a sky, fastening screw is inserted to the hole of having bored on drill bushing and support, then remaining hole on drilling machine base, makes on support the positional precision of through hole higher.
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 to improve the positional precision of support through hole, the height of increasing work efficiency.
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.
Fig. 3 is the cutaway view of Fig. 2.
Fig. 4 is the structural representation that support ear is climbed end face.
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 3, a kind of support ear is climbed the drill jig on end face, comprise the bushing plate 3 being arranged on support 4, the basic configuration of bushing plate is circular, a circular edge carries out milling and processes a chucking lug and climb 34, and chucking lug is climbed as triangle, the coincident of leg-of-mutton one side and bushing plate, a leg-of-mutton angle is a fillet towards Wai，Gai angle, edge.The shape that chucking lug is climbed is identical with the shape shape that Fig. 4 support ear is climbed, and size is also identical.The center of bushing plate is provided with a circular lightening hole 31, bushing plate is along the circumferential direction evenly equipped with drill bushing hole, 32, one, 6 drill bushing holes and is positioned at chucking lug and climbs, and is provided with drill bushing 2 in drill bushing hole, the downside of bushing plate is provided with 33, one drill bushings of centring ring cylindraceous and is provided with fastening screw 1.
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.
Claims (3)
1. a support ear is climbed the drill jig on end face, it is characterized in that, comprise the bushing plate being arranged on support, be evenly equipped with some drill bushings on bushing plate, the downside of bushing plate is provided with centring ring cylindraceous, the edge of bushing plate is provided with a chucking lug and climbs, chucking lug is climbed as triangle, the coincident of leg-of-mutton one side and bushing plate, and a leg-of-mutton angle is outside edge, this angle is a fillet, and a drill bushing is positioned at chucking lug and climbs.
