Abstract
The invention relates to a fixture for drilling an oblique oil hole. The fixture comprises a crankshaft (1), a front crankshaft bracket (2), a pressing plate (3), a screw (4), a locating block (5), a back crankshaft bracket (6), a fixed plate (7) and a drill bushing (8), wherein the front crankshaft bracket (2) and the back crankshaft bracket (6) are arranged on the fixed plate (7); the crankshaft (1) is arranged on the front crankshaft bracket (2) and the back crankshaft bracket (6); the crankshaft (1) is connected with the fixed plate (7) by the locating block (5) and fixed by the screw (4); the crankshaft (1) is fixed together with the pressing plate (3) by the screw (4); and the drill bushing (8) is arranged on the fixed plate (7). According to the invention, as the fixture has a three-dimensional angle, the fixture does not need to be rotated for an angle, so that the clamping time is greatly saved, the production quantity is greatly increased, the efficiency is increased by 50%, two oil holes of a machined big product are very well intersected with each other, and no semi-intersected product is caused.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of brill inclined oil hole of air anchor clamps.
Background technology
In the processing of crank-shaft link neck oilhole, one procedure is arranged at present; On the connecting rod neck, bore Φ 6mm inclined oil hole of air, it is straight hole and the inclined hole that bores 2 Φ 6mm at main bearing journal and connecting rod neck respectively that its process technology requires, and two holes not only will drill through; And junction, two holes must overlap, can not the handing-over of half hole.Present existing anchor clamps all are rotary jigs, need the rolling clamp angle during angular bit hole, and two screw rods and pressing plate are pressed in the angle.
Summary of the invention
Technical problem to be solved by this invention provides a kind of brill inclined oil hole of air anchor clamps, and these anchor clamps have been practiced thrift the artificial auxiliary time greatly, have improved production efficiency.
Technical scheme of the present invention: a kind of brill inclined oil hole of air anchor clamps, it comprises bent axle 1, front crankshaft support 2, pressing plate 3; Screw 4, locating piece 5, back bent axle support 6, fixed head 7 and drill bushing 8; Fixed head 7 is provided with front crankshaft support 2 and back bent axle support 6, and bent axle 1 is arranged on front crankshaft support 2 and the back bent axle support 6, and bent axle 1 is connected with fixed head 7 through locating piece 5; And fixing through screw 4, bent axle 1 is fixing with pressing plate 3 through screw 4, and drill bushing 8 is arranged on the fixed head 7.
The present invention compared with prior art has following beneficial effect: anchor clamps of the present invention have three-dimensional angle; Do not need rotary tooling anchor clamps angle; Practiced thrift the clamping time greatly, production quantity improves greatly, and efficient has improved 50%; The two oilholes handing-over that processes big product is fine, product do not occur partly joining.
Description of drawings
Fig. 1 is a structural representation of the present invention.
