Problems solved by technology
Since the press-fit part is in the cavity of the handle seat assembly, the press-fit operation is very inconvenient, and it is easy to cause the first connecting rod to be too deep or too shallow in the radial through hole of the shaft, or the second connecting rod and the shaft Not vertical, making subsequent assembly of the multi-way valve impossible

Embodiment Construction
[0025] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.
[0026] Such as figure 1 , 2 As shown in the figure, a press-fit tooling for a reversing mechanism on a load-sensitive proportional multi-way valve includes a base 6 and a handle seat 3, and the handle seat 3 is fixed on the left side of the base 6 by the first screw 1. On the side, the handle base 3 is provided with a first connecting rod 9 and a second connecting rod 10, wherein the base 6 is sequentially installed with a di...

The invention relates to a tool used for press fitting of a reverse mechanism on a load sensitive proportional multiway valve. The tool comprises a base (6) and a handle seat (3), an orientation pin (11) and a depth keeping pin (12) are arranged above the base (6), the orientation pin (11) is connected onto the base (6) by virtue of an external thread, the right end (16) of the depth keeping pin (12) is sheathed with a spring (5) and is connected with the base (6) by virtue of the round base plate (8), so as to be sealed, the middle section (15) of the depth keeping pin (12) is provided with a long slot, a third screw (4) on the base (6) is inserted and propped against the long slot, and the left end (14) of the depth keeping pin (12) causes a shaft (2) to not be rotate and to be orientedby virtue of a radial hole on the shaft (2). The tool in invention has simple structure, low manufacturing cost, good operating characteristics and long service life and can completely meet comprehensive requirement of press fitting of the reverse mechanism, thus improving assembling efficiency.
Description
technical field [0001] The invention belongs to the technical field of press-fitting tooling, in particular to a press-fitting tooling for a reversing mechanism on a load-sensitive proportional multi-way valve. Background technique [0002] At present (on the load-sensitive proportional multi-way valve) the pressure-fitting method of the reversing mechanism has the following defects: [0003] After the shaft is inserted into the corresponding hole of the handle seat, it becomes the handle seat assembly. After the first connecting rod and the second connecting rod are riveted, it becomes the connecting rod assembly. mechanism. Previously, the press fit of the reversing mechanism was done by manual positioning. Since the press-fit part is in the cavity of the handle seat assembly, the press-fit operation is very inconvenient, and it is easy to cause the first connecting rod to be too deep or too shallow in the radial through hole of the shaft, or the second connecting rod an...
