Problems solved by technology

Since the placement accuracy of the oil hole drill is very high and difficult to operate, the error of the oil hole processed in this way is relatively large, and the reject rate is high
In addition, for different types of crankshafts, the oil hole angles, main shaft diameters and connecting rod diameters are different, which results in the use of different drilling jigs for different types of crankshafts. High, many fixture replacement times, low efficiency and other defects

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0030] Such as figure 1 As shown, the position-adjustable crankshaft oil hole drilling jig mainly includes a support base 1, a guide plate 2, a clamp body 3, an N-jaw chuck 4 (a four-jaw chuck is used in the embodiment), an adjusting screw rod 6, and an angle adjusting gear 10 And positioning mechanism 12. The clamping mechanism clamps and fixes the crankshaft 5 on the clamp body 3 . The clamping mechanism and the position adjustment mechanism are fixedly connected with screws 8, and the positioning mechanism and the support base are fixedly connected with fastening screws 11.

[0031] Such as figure 2 As shown, the clamping mechanism includes a four-jaw chuck and a rotary handle 15 . The four-jaw chuck is a commonly used chuck and mainly includes a chuck body 14, a chuck through hole 13, a reinforcing rib 16 and jaws 17. When the rotary handle 1...

Abstract

The invention discloses a drilling clamp for an oil hole of a bent axle in an adjustable position. The drilling clamp comprises a clamping mechanism and a position adjusting mechanism, wherein the clamping mechanism comprises N-claw chuck and a rotary handle, wherein the N-claw chuck comprises claws and a chuck body; the position adjusting mechanism comprises a clamp body, a slide block and a guide plate; the clamp body is fixedly connected with the chuck body; at least two supporting rods are symmetrically arranged at the bottom of the clamp body; the bottoms of the supporting rods are connected with the slide block; two guide grooves are symmetrically arranged on the upper surface of the guide plate; the size of the guide grooves is matched with the size of the slide block; and under the sliding of the slide block in the guide grooves, the clamping mechanism is driven by the supporting rods to linearly move on the guide plate. The drilling clamp for the oil hole of the bent axle provided by the invention can be used for processing the oil holes in different types, sizes, positions and angles, without exchanging a clamp.

Description

technical field [0001] The invention relates to a jig, in particular to a jig used for drilling crankshaft oil holes. Background technique [0002] The crankshaft oil hole is generally fixed and placed, and the oil hole drill moves back and forth relative to the crankshaft to drill oil holes in different parts. Since the placement accuracy of the oil hole drill is very high and difficult to operate, the oil hole processed in this way has a large error and a high reject rate. In addition, for different types of crankshafts, the oil hole angles, main shaft diameters and connecting rod diameters are different, which results in the use of different drilling jigs for different types of crankshafts. High, many fixture replacement times, low efficiency and other defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crankshaft oil hole drilling jig that can process different types of crankshafts without changing t...
