Press fitting tool for assembling elastic cylindrical pin

Abstract

The invention discloses a press fitting tool for assembling an elastic cylindrical pin. A pressing head seat is provided with an assembling blind hole, a threaded through hole is formed in the side wall of the blind hole, a mounting flange is arranged on the side wall of the upper end of the pressing head seat, and a circumferential positioning groove is formed in the lower end surface of the pressing head seat; a pushing head is provided with a connecting part, a mounting flange, a spring limiting step and an extending shaft section from top to bottom in sequence, and the connecting part is in clearance fit with the interior of an assembling hole of the pressing head seat; a guiding outer sleeve is provided with a stepped inner hole, a threaded hole is formed in the upper end surface of the guiding outer sleeve, and the mounting flange is fixedly connected with the guiding outer sleeve; a guiding inner sleeve is provided with a stepped shaft hole, and elastic locking devices are arranged on the side wall of the lower end of the guiding inner sleeve symmetrically; a push rod and a small diameter section of the stepped shaft hole of the guiding inner sleeve are slidably matched, a positioning flange is arranged at the upper end of the push rod, and the positioning flange is arranged in a nut sleeve in a sleeved mode and matched with an external thread of the extension shaft section of a push head through the nut sleeve to form connection and fixing between the push rod and the push head; and a first compression spring is arranged on the extension shaft section in a sleevingmode, the upper end of the first compression spring is limited by the spring limiting step, and the lower end of the first compression spring is limited by a limiting flange.

Description

technical field [0001] The invention relates to the field of assembly tools, in particular to a pressing tool for assembling elastic cylindrical pins. Background technique [0002] At present, when assembling elastic cylindrical pins, it is usually necessary to manually hold the elastic cylindrical pins to align with the corresponding assembly holes, and another hand-held hammer to strike the elastic cylindrical pins to knock the elastic cylindrical pins into the assembly holes. The existing technical problems are : It is necessary to manually hold the hammer to knock, the operator has high labor intensity and low work efficiency; when knocking, the elastic cylindrical pin needs to be held by the hand, and the operator is easy to hurt the hand; there is no guide when knocking, once the hammer is knocked off, the elastic The cylindrical pin cannot enter the assembly hole vertically, and it is easy to damage the elastic cylindrical pin and the workpiece to be pressed, resultin...
