Lining press-fitting tool

Abstract

The invention relates to a lining press-fitting tool. The lining press-fitting tool comprises: a positioning plate is arranged above a bottom plate; a guide column is arranged between the positioning plate and the bottom plate; the lower end of the guide column is fixedly connected with the bottom plate; the upper end of the guide column stretches out of the positioning plate, and the guide column and the positioning plate form linear guide cooperation; a spring is arranged on the guide column in a sleeving way; the two ends of the spring abut against the upper plate surface of the bottom plate and the lower plate surface of the positioning plate correspondingly; two positioning pressure heads are arranged on the bottom plate and are parallel with the guide column; and the upper ends of the two positioning pressure heads stretch out of the positioning plate and are used for assembling a lining to be press-fitted. The lining to be press-fitted is arranged at the upper ends of the two positioning pressure heads and a workpiece is placed on the positioning plate of the tool, so that the upper ends, which stretch out of the positioning plate, of the positioning heads are positioned below a shaft hole of the workpiece; the tool is placed on a hydraulic press and the hydraulic press starts, so that a shaft sleeve is press-fitted on the workpiece; the workpiece is taken down after press fitting is finished, and the next press-fitting action is repeated; and the tool is convenient and safe, is quick in press fitting, and has high press-fitting precision and production efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a bushing pressing tool. Background technique [0002] The gear pump (motor) is one of the important components of the hydraulic system. Because the driving and driven gears in the hydraulic pump have the structural characteristics of being used in pairs, the bushes on the parts basically need to be used in pairs. The bushing needs to be pressed into the shaft hole of the part on the hydraulic press with a tool. In the prior art, the tools used for the bushing of the gear pump to press into the shaft hole of the part are mostly a single pressure head method, and the tool structure is simple. During operation, generally only one bushing can be press-fitted at a time; in addition, the indenter needs to be held by the hand when the bushing is initially pressed into the part, which poses a safety hazard; the indenter may also cause the bushing to be improperly pressed whe...
