Abstract
A kind of mining flange drilling jig, relate to machine-building manufacture field, its structure is: described die body (1) is annular, die body (1) is evenly provided with screw (2), positioning sleeve (4) is provided with, alignment pin A(3 in screw (2)) and alignment pin B(5) be diagonally arranged in screw.The beneficial effects of the utility model are: the utility model takes into full account the machining accuracy of workpiece, reduce the manufacturing cost of workpiece, improve the labor productivity of machining, drill jig answers structure simple, simple operation, easy handling, this flange drilling jig effect when processing method flange aperture improves more than 3 compensations, and the operation of line when decreasing punching in the past.The precision of flange there has also been very large lifting simultaneously, improves the interchangeability of flange; This drill jig is simple to operate, and clamp conveniently, it is that technique is simple that drill jig makes.
Description
one, technical field
The present invention relates to machine-building manufacture field, particularly the mining flange drilling jig of one.
two, background technology
Drill jig is in drilling processing, in order to determine the location of workpiece exactly, and the technological equipment that it is clamped securely, its Main Function is the Working position controlling cutter, reliably ensure the positional precision of processing parts, improve working (machining) efficiency, reduce labor intensity, give full play to and expand the processing performance of lathe, therefore, the design of drill jig occupies an important position in machine-building processing, during machining hole, the size of cutter is subject to the restriction of processed hole dimension, very large to the rigidity effects of cutter, hole is identical with the dimension precision requirement of periphery, hole machined often needs to spend the more time, the consumption of cutter and the probabilistic also larger of generation waste product.
three, summary of the invention
A kind of mining flange drilling jig is the invention provides for the problems referred to above, its structure is: described die body (1) is annular, die body (1) is evenly provided with screw (2), is provided with positioning sleeve (4) in screw (2), alignment pin A(3) and alignment pin B(5) be diagonally arranged in screw.
Using method of the present utility model is such: on die body (1), be evenly provided with the inner screw thread of screw (2) install positioning sleeve (4), alignment pin A(3) and alignment pin B(5), then on flange, two holes are diagonally made a call to, alignment pin A(3 by die body (1)) and alignment pin B(5) be enclosed within two holes of flange, then on flange, positioning sleeve (4) processing screw hole is passed through, when positioning sleeve (4) is worn the precision affecting processing work, positioning sleeve (4) is changed, and the die body (1) that can not wear and tear.
Play guide effect so adopt changeable positioning sleeve because positioning sleeve belongs to easily worn part, material is T10 carbon tool steel; Die body ring (1) adopts 45# steel plate to make, and supports and coordinates with adopting k7/h6 between positioning sleeve, is convenient to change; Alignment pin A(3) and alignment pin B(5) positioning head has processing 5x45 ° of chamfering, be convenient to install, alignment pin adopts Cr12 high carbon and chromium tool steel.
Beneficial effect of the present invention is: the utility model takes into full account the machining accuracy of workpiece, reduce the manufacturing cost of workpiece, improve the labor productivity of machining, drill jig answers structure simple, simple operation, easy handling, this flange drilling jig effect when processing method flange aperture improves more than 3 compensations, and the operation of line when decreasing punching in the past.The precision of flange there has also been very large lifting simultaneously, improves the interchangeability of flange; This drill jig is simple to operate, and clamp conveniently, it is that technique is simple that drill jig makes.

detailed description of the invention
Embodiment 1, a kind of mining flange drilling jig, its structure is: described die body (1) is annular, die body (1) is evenly provided with screw (2), positioning sleeve (4) is provided with, alignment pin A(3 in screw (2)) and alignment pin B(5) be diagonally arranged in screw.
Using method of the present utility model is such: on die body (1), be evenly provided with the inner screw thread of screw (2) install positioning sleeve (4), alignment pin A(3) and alignment pin B(5), then on flange, two holes are diagonally made a call to, alignment pin A(3 by die body (1)) and alignment pin B(5) be enclosed within two holes of flange, then on flange, positioning sleeve (4) processing screw hole is passed through, when positioning sleeve (4) is worn the precision affecting processing work, positioning sleeve (4) is changed, and the die body (1) that can not wear and tear.
Play guide effect so adopt changeable positioning sleeve because positioning sleeve belongs to easily worn part, material is T10 carbon tool steel; Die body ring (1) adopts 45# steel plate to make, and supports and coordinates with adopting k7/h6 between positioning sleeve, is convenient to change; Alignment pin A(3) and alignment pin B(5) positioning head has processing 5x45 ° of chamfering, be convenient to install, alignment pin adopts Cr12 high carbon and chromium tool steel.
Claims (1)
1. a mining flange drilling jig, is characterized in that: described die body (1) is annular, die body (1) is evenly provided with screw (2), is provided with positioning sleeve (4), alignment pin A(3 in screw (2)) and alignment pin B(5) be diagonally arranged in screw.
