Abstract

The invention discloses a limiting mechanism for a double-hole bushing, and relates to the technical field of part positioning, in particular to a limiting mechanism for positioning of a double-hole bushing. A material channel is arranged at the upper part of one side of the front surface of a vertical plate; a bushing adjusting device is arranged on the portion, below the material channel, of thevertical plate; the double-hole bushing slides onto the bushing adjusting device through the material channel, and the position is adjusted by the bushing adjusting device; a sliding device is arranged on one side of the vertical plate and is opposite to the bushing adjusting device; a sliding table pushes an air cylinder on the portion, at the upper part of the sliding device, of the vertical plate, is connected with the sliding device through a connecting piece and can drive the sliding device to move transversely; a limiting pin connecting rod device is arranged on the sliding device; anda limiting pin pushes the air cylinder to be installed on the sliding device through an air cylinder mounting plate and is connected with the limiting pin connecting rod device through a nut and a fixing structure. According to the technical scheme, the problems that in the prior art, the limiting error rate of one limiting pin to the double-hole bushing is 50%, two limiting pins cannot be synchronously inserted into limiting holes, and the limiting accuracy is less than 100% are solved.

Description

technical field [0001] The invention discloses a double-hole bushing limiting mechanism, which relates to the technical field of parts positioning, in particular to a limiting mechanism for double-hole bushing positioning. Background technique [0002] Before press-fitting the camshaft bushing of the cylinder block, the position of the bushing needs to be limited, so that the indenter can lift the material easily. After lifting the material, the bushing can be pressed into the corresponding position of the cylinder body. However, how to limit the bushing is a difficult point, because the diameter of the bushing is large or small, and the height of the bushing is also high or low. There is 1, there are 2 and so on. If there is only one round oil hole in the bushing, the design is simple, and only a pin can be used to restrain the bushing. And if there are two round oil holes on the bushing, and there are position requirements on the cylinder block, the design will be relati...
