SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a jig is in order to solve because of the wearing and tearing of bushing plate tang, leads to changing the problem with high costs of jig.
In order to solve the technical problem, the utility model provides a following technical scheme:
a drill jig comprises a drill jig plate, wherein a through hole is formed in the drill jig plate, and a drill bushing is arranged in the through hole; the drill jig plate is detachably connected with a positioning plate.
The drilling template is provided with a central hole, and the positioning plate is provided with a boss matched with the central hole.
Wherein, the locating plate passes through the screw and is connected with bushing plate.
The upper end face of the drill jig plate is provided with two screw holes so as to install a threaded handle when the drill jig is taken and placed.
Wherein, the jig comprises a positioning pin matched with the drill bushing.
Wherein, the number of locating pin is two.
The notch is positioned on one side of the upper end face of the drill sleeve, and one drill sleeve corresponds to one compression screw.
The utility model discloses an above-mentioned technical scheme's beneficial effect as follows:
in the scheme, the drill jig adopts a mode of combining the positioning plate and the drill jig plate, the detachable positioning plate is used for replacing a spigot structure of a traditional drill jig plate, only the positioning plate needs to be replaced after the drill jig is worn, the input cost is reduced, meanwhile, the drill bushing adopts the replaceable drill bushing, the drill bushing can be replaced at any time after being worn, and the input cost is low. For processing workpieces with different inner hole diameters and/or different hole diameters needing to be drilled and the same other processing requirements, the method for replacing the positioning plate and/or the drill bushing can be correspondingly adopted, so that the cost investment can be reduced, and the use requirements can be timely met.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 7, an embodiment of the present invention provides a drill jig, including a drill plate 2, a through hole 22 is opened on the drill plate 2, a drill bushing 3 is arranged in the through hole 22, a notch is arranged on an upper end surface of the drill bushing 3, and the drill bushing 3 is fixed on the drill plate 2 by fastening a compression screw 4 in the notch; drilling jig 2 can dismantle and be connected with locating plate 1 to replace the tang structure of traditional drilling jig, only need change locating plate 1 after wearing and tearing.
The drilling template 2 is provided with a central hole 21, the positioning plate 1 is provided with a boss 11 matched with the central hole 21, and the boss 11 is inserted into the central hole 21 during installation to play a role in positioning and fixing.
As shown in fig. 4, the positioning plate 1 is connected to the drilling template 2 by four annularly and uniformly distributed screws.
As shown in fig. 2, two screw holes 23 are symmetrically formed on the upper end surface of the drilling template 2, so that a threaded handle can be installed when the drilling template is taken and placed.
As shown in fig. 1, the drill jig comprises a positioning pin 5 matched with the drill bushing 3, and the positioning pin 5 plays a role in positioning the drill jig during drilling.
The number of the positioning pins 5 is two, the drill jig is clamped on a workpiece, a first hole is drilled, one positioning pin 5 is inserted, a second hole is drilled on the opposite side of the first hole, the second positioning pin 5 is inserted, and then the holes are drilled sequentially.
As shown in fig. 7, the notch 31 is located on one side of the upper end surface of the drill bushing 3, and one drill bushing 3 corresponds to one compression screw 4.
