Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, and specifically relates to a tooling for press fitting, and also relates to an assembly method of the tooling. Background Art

[0002] A combined component needs to assemble workpieces. During the assembly process, a workpiece with a polygonal upper part, a circular lower part, and a boss hole in the middle needs to be inserted into a hole of a component with a polygonal upper part and an elastic clamp at the lower part. When the workpiece is inserted into the hole of the component, the elastic clamp first axially contracts under the constraint of the boss in the hole of the component, and then expands after passing through the boss to clamp the workpiece in the hole of the component. During assembly, since the elastic clamp of the workpiece axially contracts under the constraint of the boss in the hole of the component, axial resistance will be generated. Moreover, the clearance between the polygonal hole of the component and the polygonal outer shape of the upper part of the workpiece is relatively small after assembly. Therefore, before the workpiece is pressed into the component, their polygonal projections must be accurately aligned and overlapped in order to press the workpiece into the component. Therefore, a precisely positioned and oriented press fitting device is required to be competent. Currently, there is no press fitting device that meets the above functional requirements. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above difficulties and provide a tooling for press fitting with precise positioning, orientation, high quality, high efficiency, convenience and speed, and an assembly method thereof.

[0004] The purpose of the utility model and the solution to its main technical problems are achieved by adopting the following technical solutions:

[0005] A tooling for press fitting of the utility model includes a press fitting mandrel, a ejector rod, a support sleeve, a spring, a base, a guide sleeve, a slide plate, a slide seat, a positioning pin, and a V-shaped hole. Its characteristics are as follows: The slide plate is clamped into the slide seat, the slide seat is placed on the base and connecting screws are respectively screwed in. The guide sleeve and the positioning pin are respectively screwed into the slide plate, and hexagon thin nuts are respectively screwed into the guide sleeve and the positioning pin. The ejector rod is sleeved with a spring and screwed into the support sleeve, the ejector rod passes through the base and is screwed into the support sleeve, and a V-shaped hole is provided on the base.

[0006] One end of the slide seat is screwed with a set screw, and a hexagon thin nut is screwed on the set screw, and the set screw contacts the positioning pin.

[0007] A handle is installed on the ejector rod.

[0008] A press fitting mandrel is inserted into the guide sleeve.

[0009] Compared with the prior art, the present invention has obvious beneficial effects. It can be seen from the above technical solution that the press-fitting mandrel is connected to the power head of the pressure equipment and can move up and down. The various parts of the tooling have been assembled, but the hexagonal thin nuts and screws are not tightened. The tooling base is placed on the workbench of the pressure equipment. The component hole is placed upward in the V-shaped hole in the center of the base and contacts the V-shaped surface. The positions of the base, slide plate, slide seat and guide sleeve are adjusted so that the press-fitting mandrel passes through the polygonal hole of the guide sleeve and is inserted into the polygonal section on the upper part of the component hole. The distance between the lower end face of the guide sleeve and the upper end face of the component is less than the thickness of the polygon on the upper part of the workpiece. At this time, the polygonal axis and hole of the press-fitting mandrel, guide sleeve and component are aligned and the projections overlap. The position of the set screw is adjusted so that its right end face contacts the locating pin. Then the base is fixed on the workbench of the pressure equipment. The connecting screws and hexagonal thin nuts are tightened to fix the positions of the slide seat, set screw and guide sleeve. The press-fitting mandrel is moved upward and the tooling installation is completed. When press-fitting a workpiece, move the push rod to the right and the slide to the left, place the component on the press-fitting mandrel and place it in the V-shaped hole in the center of the base, loosen the push rod and move it to the left to press the component. Move the press-fitting mandrel upwards and move the slide to the right until the locating pin contacts the set screw. At this time, the press-fitting mandrel, guide sleeve, polygonal axis, and hole of the component are aligned, and the projections overlap. Insert the workpiece elastic card downward into the polygonal hole of the guide sleeve, and then insert the press-fitting mandrel into the polygonal hole of the guide sleeve. Move the press-fitting mandrel downwards until the workpiece is pressed into the component hole to complete the assembly. Move the press-fitting mandrel upwards, move the push rod to the right to loosen the component, and move the slide to the left to remove the assembled component. Repeat the above operation to press-fit the workpiece again. The workpiece press-fitting has good quality, is convenient and quick to operate, and is highly efficient.
