Abstract
Hole square seal ring assembles device, being press-fited body by elasticity and positioning and guiding bullet is constituted, elasticity press-fits installation back-moving spring at internal central upper portion, and positioning and guiding bullet is installed on piston, elasticity press-fits body top and is provided with handle, and positioning and guiding bullet top is provided with locating dowel.The hole square seal ring of the present invention assembles device, during pilot hole square seal ring, not only ensure that the external cylindrical surface of hole square seal ring does not scratch and damaged, and circularity is good, it is ensured that assembling quality, substantially increase work efficiency, simple in construction, easy to use, reduce labor intensity.
Description
Technical field
The present invention relates to parts mounting technology field, particularly relate to the mounting technology field of hole square seal ring on piston.
Background technology
During cylinder efficient, piston reciprocating moves, it is ensured that two chamber hydraulic oil are not ganged up, it is necessary to the external cylindrical surface of hole square seal ring does not scratch and damaged, and circularity to be got well.Due to hole square seal ring by material be PTFE Bronze composites sintering form, the plastic deformation caused during assembling can also carry out Shape correction and reach technology requirement.At present, the assembling of hole square seal ring, the method that widely used free-hand set is close, use such method inefficiency, labor intensity is big, and most importantly easily to be scratched or assemble strength by wedge angle burr uneven and cause crushing on sealing part works surface, causes sealing function to lose efficacy.
Summary of the invention
Big in order to solve free-hand set sealing ring inefficiency, labor intensity, external cylindrical surface easily scratches and the problem such as damaged, the invention provides a kind of hole square seal ring and assembles device.
The present invention the technical scheme is that hole square seal ring assembles device, elasticity press-fit body and positioning and guiding bullet is constituted, and elasticity press-fits installation back-moving spring at internal central upper portion, and positioning and guiding bullet is installed on piston.
Described elasticity press-fits body top and is provided with handle.
Described positioning and guiding bullet top is provided with locating dowel.
The hole square seal ring of the present invention assembles device, during pilot hole square seal ring, not only ensure that the external cylindrical surface of hole square seal ring does not scratch and damaged, and circularity is good, it is ensured that assembling quality, substantially increase work efficiency, simple in construction, easy to use, reduce labor intensity.

Fig. 2 is the positioning and guiding bullet sectional view of hole of the present invention square seal ring assembling device.
Fig. 3 is the sectional view of piston.
Fig. 4 is that square seal ring assembling device in invention hole is press-fit into place view.
In figure: handle 1, elasticity press-fit body 2, back-moving spring 3, positioning and guiding bullet 4, hole square seal ring 5, piston 6, locating dowel 7.
Detailed description of the invention
The hole of the present invention is by the structure of square seal ring assembling device as depicted in figs. 1 and 2, press-fited body 2 by elasticity and positioning and guiding bullet 4 is constituted, elasticity press-fits the housing internal upper part center of body 2 and installs back-moving spring 3, elasticity press-fits body 2 top and is provided with handle 1, positioning and guiding bullet 4 top is provided with locating dowel 7, during use, positioning and guiding bullet 4 lower end is inserted on piston 6, and piston structure is as shown in Figure 3.
Use process and principle are as follows: positioning and guiding bullet 4 (conical surface is smooth) is first inserted in piston 6 hole by (1).(2) hole square seal ring 5 is inserted on positioning and guiding bullet 4 conical surface in advance；(3) elasticity press-fits body 2 and guarantees that compression spring 3 internal diameter is inserted in the locating dowel 7 of positioning and guiding bullet 4；(4) compression elasticity of exerting oneself press-fits body 2, and elasticity press-fits body 2 head that rises and by conical surface power effect swell and promotes hole square seal ring 5 along conical surface slide downward, until be press-fit into place, is press-fit into place state as shown in Figure 4；(5) elasticity press-fit body 2 not give external force time, elasticity press-fits body 2 and ejects positioning and guiding bullet 4 under the effect of back-moving spring 3 power；(6) take out positioning and guiding bullet, press-fit complete, complete hole square seal ring and assemble.
