Abstract
The utility model discloses a drill jig of bearing seat thread bottom holes. The drill jig of the bearing seat thread bottom holes is characterized in that a drill jig plate arranged on a bearing seat is included, the drill jig plate is circular, a positioning block I is arranged on the lower side face of the drill jig plate, the positioning block I is circular, the positioning block I coincides with the axial center line of the drill jig plate, a plurality of drill bushing holes are formed in the plate surface of the drill jig plate except for the positioning block I, the drill bushing holes are respectively provided with a drill bushing, a positioning block II is arranged on the edge of the drill jig plate, and the positioning block II is rectangular. The drill jig plate is placed on the bearing seat, and the positioning block I and the positioning block II are used for enabling the drill jig plate to be positioned on the bearing seat, the positions of the drill bushings on the drill jig plate are the positions of the bearing seat thread bottom holes, so that hole drilling can be achieved without marking and punching sampling, and the working efficiency and the position precision of the holes are improved.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of drill jig.
Background technology
Bearing block is for spring bearing, and extensive in application in machine equipments, bearing block is generally connected with adjacent part by bolt and nut, so must bore connecting hole on bearing block.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 bearing block be connected with other part, 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 a kind of bearing block thread Pilot hole 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 bearing block thread Pilot hole drill jig, it is characterized in that, comprise the bushing plate being arranged on bearing block, described bushing plate is circular, and the downside of bushing plate is provided with locating piece I, locating piece I is circular, locating piece I overlaps with the longitudinal center line of bushing plate, and the bushing plate plate face beyond locating piece I is provided with some drill bushings hole, and drill bushing is respectively equipped with drill bushing on hole, the edge of bushing plate is provided with a positioning block II, and locating piece II is rectangle.Bushing plate is placed on bearing block, by locating piece I and locating piece II, bushing plate is located on bearing block, on bushing plate, the position of drill bushing is exactly the position of bearing block thread Pilot hole, so need not rule, rushes sample and can hole, and has improved the positional precision in operating efficiency and hole.
As preferably, described bushing plate and locating piece Ⅰ center are provided with a lightening hole, alleviate the weight of bushing plate, handled easily.
As preferably, described bushing plate, locating piece I and the locating piece II structure that is formed in one.
Main beneficial effect of the present utility model is, can increase work efficiency, and reduces labor strength, improves the positional precision in hole, eliminates and interferes, and improves the quality of products.
Accompanying drawing explanation
Fig. 1 is that the utility model is assemblied in the structural representation on bearing block.
Fig. 2 is structural representation of the present utility model.
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, a bearing block thread Pilot hole drill jig, comprises the bushing plate 1 being arranged on bearing block 5, and described bushing plate is circular, the downside of bushing plate is provided with locating piece I 6, locating piece I is circular, and locating piece I overlaps with the longitudinal center line of bushing plate, and the bushing plate plate face beyond locating piece I is provided with four drill bushing holes 7, four drill bushing holes are distributed on a circumference, on drill bushing hole, be respectively equipped with drill bushing 4, the edge of bushing plate is provided with a positioning block II 8, and locating piece II is rectangle.Described bushing plate and locating piece Ⅰ center are provided with a lightening hole 2.Described bushing plate, locating piece I and the locating piece II structure that is formed in one.Because the aperture of thread Pilot hole is less than φ 10, so hole on bench drill, during use, operating procedure is as follows: 1. the locating piece I on bushing plate is inserted to the endoporus of bearing block, made the coincident of locating piece II and bearing block, bushing plate is located on bearing block; 2. start drilling machine, with hand, live first thread Pilot hole of drill jig twist drill; 3. in the position of boring good first thread Pilot hole, insert fastening screw 3; 4. once bore its excess-three thread Pilot hole; 5. from bearing block, take off fastening screw and bushing plate, from drilling machine, take off bearing block, bore 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.
