Problems solved by technology

[0003] Since the engine is prone to loose timing gears and flanges during use, it is necessary to test the pull-out force of the camshaft and timing gears so that the designer can adjust the relevant parameters. Since the timing gears and flanges have a large interference Installed together after heating, a relatively large force is required to test the pull-off force, and the existing test method uses hanging pull-off, which is easily affected by external forces, resulting in inaccurate test results

Abstract

The embodiment of the invention discloses a pulling-out tool. The pulling-out tool comprises a base, a clamp and a pulling-out mechanism. The clamp comprises a front supporting plate and a rear supporting plate. The front supporting plate is fixedly connected with the rear supporting plate; the front supporting plate and the rear supporting plate are both fixed to the upper surface of the base; the pulling-out mechanism comprises a power device, a pressure sensor and a fixed pulling piece; the power device is installed in the middle of the front supporting plate, a piston rod of the power device is located between the front supporting plate and the rear supporting plate, and the pressure sensor is installed on the piston rod and used for sensing an extrusion force of the piston rod of thepower device for ejecting a camshaft; the fixed pulling piece is installed in the middle of the rear supporting plate and used for clamping and fixing a correct timing gear of the camshaft; and the supporting front plate and the rear supporting plate are parallel to each other and are perpendicular to the upper surface of the base, and when the camshaft is pulled out, the vertical section of the camshaft is perpendicular to the plane where the front supporting plate is located. The device is convenient for testing the pulling-out force of the camshaft and the correct timing gear.

Description

technical field [0001] The embodiments of the present application relate to the technical field of engine tooling, and in particular, to a pull-out tooling. Background technique [0002] A camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. Usually it has a high speed and needs to bear a lot of torque, so the design requires high strength and support for the camshaft. [0003] Since the timing gear and flange are prone to loosening during the use of the engine, it is necessary to test the pull-out force of the camshaft and the timing gear so that the designer can adjust the relevant parameters. After being heated and installed together, a relatively large force is required to test the pull-out force, and the existing test method is to use a hanging pull-out, which is easily affected by external forces, resulting in inaccurate test results. SUMMARY OF THE INVENTION [0004] The embodiment of the present application...
