Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] like figure 1 and figure 2 As shown, the present invention includes a support 1 , a positioning shaft 2 , two guide keys 3 and a pressing block 4 . The support 1 is an arc-shaped structure, the middle part of which extends upwards a positioning boss 11, and the bottom of the support 1 is provided with an arc-shaped positioning groove 12. The support 1 is supported on the cam base circle 5 corresponding to the camshaft of the diesel engine, and the camshaft of the diesel engine corresponds to the cam base circle 5. The base circle 5 is inserted into the arc-shaped positioning groove 12 at the bottom of the support 1 . The lower end of the positioning shaft 2 vertically passes through the installation hole of the diesel engine roller and is supported on the upper side of the support 1. The bottom of the positioning shaft 2 is provided with a positioning groove 2...

Abstract

The invention discloses a roller lining installation positioning device and method. The device comprises a support, a positioning shaft, multiple guide keys and a pressing block. The support is supported on a diesel engine cam shaft corresponding cam base circle, the lower end of the positioning shaft is supported on the upper side of the support, one side of the positioning shaft is provided withan axially-through first guide groove, the multiple guide keys are axially overlapped in the lower end of the first guide groove, the middle of the positioning shaft is sleeved with a roller lining in a sliding mode, the upper end of the positioning shaft is sleeved with the pressing block in a sliding mode, and the pressing block presses the top of the roller lining. The structure is simple andcompact, assembly and disassembly are convenient, installation requirements of different specifications of roller linings can be met, and universality is high. The roller lining can be pressed in place only by pressing down the pressing block, operation and use are quite convenient, time and labor are saved, and the working efficiency is high. The roller lining is free of shaking and shifting in the pressing process, it is ensured that positioning of the roller lining is accurate without error in the pressing process, and therefore the installation precision and position precision of the roller lining are ensured.

Description

technical field [0001] The invention relates to a diesel engine roller bush installation tool, in particular to a diesel engine roller bush installation tool with accurate positioning and an installation method, belonging to the technical field of diesel engine auxiliary installation tools. Background technique [0002] Separate roller bushing is an important part of diesel engine, its installation accuracy and position accuracy are directly related to the reliability and stability of diesel engine operation. Roller bushings are generally installed with special tools using the press-in method. The existing diesel engine roller bushing installation tools have complex structures and cumbersome operations. It often takes a long time and a lot of manpower to press the roller bushes in place. Low, and the installation accuracy and position accuracy of the roller bushing cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a...
