Problems solved by technology

In addition, for different types of crankshafts, the oil hole angle, the diameter of the main shaft and the diameter of the connecting rod are different, which results in the use of different drilling jigs for different types of crankshafts. High, long production cycle, many clamping and replacement times, low efficiency and other defects

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the crankshaft multi-angle oil hole drilling jig of the present invention includes a crankshaft clamping mechanism, a clamp body 9, an angle adjustment disc 14, a positioning support seat 19, a right-angle positioning block 21 and a right-angle slider positioning mechanism.

[0023] When machining the crankshaft, the crankshaft clamping mechanism is mainly used to clamp and fix the crankshaft. Figure 4 The crankshaft clamping mechanism shown includes swing bolt 1, replaceable pad 2, gland 3, hinge pin 4, V-shaped support seat 5, clamping mechanism fixing screw 6, replaceable support block 7 and T-shaped projection 8 . Figure 4 The V-shaped support seat 5 in the middle is the crankshaft support seat. exist Figure 4 Among them, there is an open V-shaped groove in the center of the V-shaped support seat 5 . The gland 3 is installe...

Abstract

The invention discloses a crankshaft multi-angle oil hole drilling clamp. A crankshaft supporting seat of each crankshaft clamping mechanism is provided with a groove; a gland is arranged above the groove; two ends of the gland are movably connected with the crankshaft supporting seat respectively; a clamp body is uniformly and circumferentially provided with six rotating pin holes and two rotating screw holes taking a bearing hole of the clamp body as a center; six screw holes corresponding to the rotating screw holes, pin holes corresponding to the rotating pin holes and small-angle adjustment screw holes are arranged around a spindle hole of an angle adjustment disc; a circle center-connecting line of two mutually symmetric small-angle adjustment screw holes passes through the circle center of the spindle hole, and adjacent circle center-connecting lines form an included angle; an orthogonal surface of an orthogonal positioning block is provided with two holes of which the circle center-connecting line is a horizontal line; the orthogonal positioning block is arranged together with the angle adjustment disc and a supporting base; the angle adjustment disc is between a positioning supporting seat and one side of the clamp body; the crankshaft clamping mechanisms are symmetrically arranged at two ends of the other side of the clamp body; and an orthogonal slider positioning mechanism is arranged between two crankshaft clamping mechanisms.

Description

technical field [0001] The invention relates to a jig for drilling a crankshaft oil hole. Background technique [0002] Present crankshaft oil hole is divided into two kinds of straight oil hole and oblique oil hole, and the position of oil hole is on the main journal, or is positioned on the main journal and connecting rod journal. The straight oil hole on the main journal can be processed on an ordinary drilling machine; the machining of the oblique oil hole on the main journal and connecting rod neck is more complicated and needs to be divided into two processes to complete: one process is to drill the main journal The other process is to drill the inclined oil hole on the connecting rod neck. The oil holes in the two parts must be connected to form a passage after processing. Therefore, the requirements for the positioning of the oil holes in the two processes are relatively high. In addition, for different types of crankshafts, the oil hole angle, the diameter of the m...
