The device comprises a positioning element, a clamping mechanism and a drill bushing fixed on a drill plate; the positioning element is a cylindrical positioning seat (7), the top surface of the positioning seat is provided with two positioning pin holes (10), and the outer wall of the positioning seat (7) is fixed with two hinged seats (9); the clamping mechanism is composed of swing bolts respectively pivoted on the hinge seats (9) and butterfly nuts (4) respectively arranged on the swing bolts; two positioning pins (1) matched with the corresponding positioning pin holes (10) are fixed on the back of the drill plate (2), and two U-shaped lug seats (11) which are fixedly connected with the drill plate (2) into a whole and correspond to the swing bolts in position are arranged on the drill plate (2). The special drill jig for the thin-wall shell parts is simple in structure and convenient to use.
Description
Technical Field
The invention relates to a drill jig, in particular to a motor shell flange hole system drill jig; belongs to mechanical processing technical equipment.
Background
The motor shell is a cylindrical thin-wall shell part; in order to facilitate the disassembly and assembly, the port connection is usually designed to be a flanged structure with a flange. However, it is difficult to form the bolt hole system at the burring because the burring is formed during the drawing process at the burring. At present, two modes of manual marking and drilling and die punching are mainly adopted. Although manual scribing and drilling are simple, the defects of difficult clamping, easy slipping of a drill bit, low efficiency and the like exist, and the position precision between hole systems cannot be ensured. Although the punching efficiency of the die is high, the position precision between hole systems can be ensured, but the workpiece is easy to deform due to the uneven cutting edge of the female die, and the die is difficult to manufacture and high in cost.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the motor shell flange hole system drill jig which is high in machining efficiency and good in hole system position precision.
In order to achieve the purpose, the invention adopts the following technical scheme: the device comprises a positioning element, a clamping mechanism and a drill bushing fixed on a drill plate; the positioning element is a cylindrical positioning seat, the top surface of the positioning seat is provided with two positioning pin holes, and the outer wall of the positioning seat is fixedly provided with two hinged seats; the clamping mechanism is composed of swing bolts respectively pivoted on the hinge seats and butterfly nuts respectively arranged on the swing bolts, and each swing bolt is composed of a pin shaft arranged in the hinge seat and a stud fixedly connected with the pin shaft into a whole; two positioning pins matched with the corresponding positioning pin holes are fixed on the back of the drill plate, and two U-shaped lug seats which are fixedly connected with the drill plate into a whole and correspond to the swing bolts in position are arranged on the drill plate.
Compared with the prior art, the invention has the following advantages due to the adoption of the technical scheme:
1) the parts are reliably positioned and are conveniently and quickly clamped;
2) due to the limitation of the drill bushing, the drill bit can be effectively prevented from swinging and slipping, and the mutual position precision between the hole systems is accurate;
3) simple structure, convenient use, high processing efficiency and no deformation of the workpiece.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
FIG. 3 is a top view of FIG. 1;
FIG. 4 is a schematic structural view of a motor housing (thin-walled shell type workpiece);
fig. 5 is a top view of fig. 4.
In the figure: the drilling jig comprises a positioning pin 1, a drilling template 2, a motor shell 3, a butterfly nut 4, a stud 5, a pin shaft 6, a positioning seat 7, an inner cylindrical surface 8, a hinge seat 9, a positioning pin hole 10, a U-shaped lug seat 11 and a drill bushing 12.
Detailed Description
The invention is further described with reference to the following figures and specific examples.
As shown in fig. 1-5: the positioning element is a cylindrical positioning seat 7, and an inner cylindrical surface 8 of the positioning seat is a positioning surface; the top surface of the positioning seat 7 is provided with two positioning pin holes 10, and the outer wall of the positioning seat is provided with two hinged seats 9 which are connected with the positioning seat into a whole. Each hinged seat 9 is respectively pivoted with an eyelet bolt, and each eyelet bolt is respectively provided with a butterfly nut 4; the swing bolt and the wing nut 4 together form a clamping mechanism. The swing bolt is composed of a pin shaft 6 arranged in a hinge seat 9 and a stud 5 welded on the pin shaft. Four drill bushings 12 are fixedly embedded in the drill plate 2, two positioning pins 1 matched with the corresponding positioning pin holes 10 are fixed on the back of the drill plate, and U-shaped lug seats 11 which are fixedly connected with the left end and the right end of the drill plate 2 into a whole and correspond to the eyelet bolts in position are arranged at the left end and the right end of the drill plate 2.
When in use, the motor shell 3 is placed in the inner hole of the positioning seat 7, and the inner cylindrical surface 8 of the positioning seat is used for positioning the motor shell 3; the drilling template 2 is fixed on the upper end face of the positioning seat 7 through the positioning pin 1 and the positioning pin hole, and then the motor shell 3 is pressed and fixed through the drilling template 2 by using the swing bolt and the butterfly nut 4.
