Problems solved by technology

[0003] Although the existing installation method can realize the installation of the bushing, it has the following disadvantages: if the visual method is used for installation, it is easy to cause installation deviation, the pass rate is low, the assembly consistency is poor, and the cost of destructive repair is high; The cost of production input is high, the flexibility of the production line is reduced, and it is difficult to change the mold quickly

Embodiment Construction

[0015] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0016] Such as Figure 1~2 As shown, the present invention mainly includes a compression rod, which is a cylinder. The pressure rod includes a handle part 1, a shoulder part 2, a bush installation part 3, a transition part 4 and a guide positioning part 5, the handle part 1, a shoulder part 2, a bush installation part 3, a transition part 4 and a guide positioning part The parts 5 are connected end to end in turn to form a whole.

[0017] The surface of the handle part 1 is provided with reticular lines, which improve the frictional force and facilitate manual clamping.

[0018] The end face of the convex shoulder 2 is perpendicular to the axis of the pressure rod, so as to ensure that the bush can be evenly stressed at 360° during the process of using tools to install the bush, and reduce the deformation of the bush.

[0019] The diameter of the tr...

Abstract

The invention relates to a camshaft bush installation, in particular to a camshaft bush installation tool, which belongs to the technical field of camshaft bush installation equipment. It includes a pressing rod, and the pressing rod includes a handle part, a convex shoulder part, a bush installation part, a transition part and a guide positioning part. The bush installation part is provided with a first positioning hole in the radial direction, and the first through hole section is provided with a The first positioning steel ball, the part of the first positioning steel ball can protrude from the outer surface of the bushing installation part; the internal thread of the first threaded hole section is connected to the first adjusting screw, and the first positioning steel ball and the first adjusting screw are provided with a second positioning screw. A spring, the compression degree of the first spring to the first positioning steel ball can be adjusted through the first adjusting screw. The protruding shoulder of the pressure rod of the present invention realizes the positioning of the installation depth of the bushing, and the guide part realizes the angle positioning of the oil hole of the bushing; The accurate butt joint of the holes realizes the accurate positioning of the bushing angle.

Description

technical field [0001] The invention relates to a camshaft bush installation, in particular to a camshaft bush installation tool, which belongs to the technical field of camshaft bush installation equipment. Background technique [0002] In the process of diesel engine production, sample trial production, and maintenance, it is generally necessary to assemble and disassemble camshaft bushings. Commonly used bushing installation methods, one is to install by visual method, by visually aligning the angle between the bush and the lubricating oil channel of the cylinder block or cylinder head, and knocking in with a knocking rod; the other is by equipment installation, by positioning the cylinder block or cylinder Then calculate the installation angle of the lubricating oil hole of the bushing, and press and install the bushing. [0003] Although the existing installation method can realize the installation of the bushing, it has the following disadvantages: if the visual metho...
