Abstract
The utility model discloses a combined piston for vehicles and relates to an important working part arranged on a piston rod in a guider of a vehicle. The combined piston is mainly formed by a left half body and a right half body which are assembled mutually and provided with installation holes and circulation holes. The combined piston is characterized in that the left half body and the right half body are formed by being extruded by a fastening pin assembled in location mode in one time, thereby simplifying mould manufacture, enabling manufacture process to be simple and assembling accuracy to be high, and effectively reducing production cost. The combined piston has the advantages of being compact in structure, light in weight, quick and stable in batch production, good in integrity and the like.
Description
Technical field
The utility model relates to a kind of structure of combined piston, is meant automobile-used combined piston specifically.
Background technique
Combined piston is the important process parts that are installed in the vehicle guidance device on the piston rod; Usually be formed by connecting two halfbodies are equipped mutually; On halfbody, also be provided with mounting hole and a plurality of be the opening that circumference uniform distribution is made in the center of circle with the mounting hole; After linking into an integrated entity, set mounting hole and opening just is corresponding one by one communicating state on two halfbodies.But the combined piston that uses at present is as shown in Figure 5, mainly is that both ends of the surface at left and right halfbody are respectively equipped with six concavo-convex holes and to be assembled into combined piston overall; This structural design powder metallurgy is difficult to the moulding manufacturing, adopts the casting transfer mold to make, and needs through bigger turning; Grind and make; The technology very complicated, not only the component precision is not high, and fabricating cost is high.
Summary of the invention
The utility model technical problem to be solved is to overcome the defective of existing technology and the automobile-used combined piston that a kind of once promptly plastic, manufacturing process is simple, assembly precision is higher, can effectively reduce production costs is provided.
The technical problem of the utility model realizes through following technological scheme:
A kind of automobile-used combined piston; Comprise left halfbody and right halfbody; Be respectively equipped with on the both ends of the surface of this left and right halfbody mounting hole and a plurality of be the opening that circumference uniform distribution is made in the center of circle with the mounting hole; The both ends of the surface of this left and right halfbody are equipped mutually to link into an integrated entity; And make corresponding connection of mounting hole and opening on the left and right halfbody, the equipped mutually structure of described left and right halfbody both ends of the surface is in the mounting hole of left and right halfbody both ends of the surface, to be provided with the equipped fixed pin in location, and through this fixed pin with an extrusion modling of left and right halfbody.
Described left and right halfbody structure is identical and in the form of annular discs, and the opening on these left and right halfbody both ends of the surface is 4 ~ 6 of circumference uniform distribution.
Compared with prior art; The utility model mainly is to adopt the equipped fixed pin in location to do an extrusion modling the left and right halfbody that constitutes combined piston; This once-through structure can be simplified Mold Making; Make that manufacturing process is simple more, assembly precision is higher, and can effectively reduce production costs, the structure after the improvement more close-fitting and have in light weight, produce more advantages such as fast and stable, integrity be better in batches.

Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
Like Fig. 1～shown in Figure 5,1. left halfbody, 2. right halfbody, 3. opening, 4. fixed pin, 5. mounting hole, 6. salient point.
Automobile-used combined piston; Adopt the powder metallurgy once-through; Mainly by two left and right halfbodies in the form of annular discs, and 4 of fixed pins constitute, described left halfbody 1 is identical with right halfbody 2 structures, the mounting hole 5 and 4 that are equipped with a center as shown in Figure 2 on the end face of this left and right halfbody are the opening 3 that circumference uniform distribution is made in the center of circle with the mounting hole; Described mounting hole 5 is designed to the shoulder hole structure; Described fixed pin 4 is placed in the center mounting hole 5 of the left and right halfbody after the merging, is provided with salient point as shown in Figure 36 structures in fixed pin 4 outers, is mainly used in the location that guarantees fixed pin and mounting hole 5 and is provided with.After the equipped completion of three, insert mould and form close-connected integral structure through a punching press of finishing machine, the opening on the left and right halfbody also is the state of being interconnected at this moment.
The utility model has been cancelled the equipped structure in six concavo-convex holes of left and right halfbody employing in original combined piston; And change to fixed pin 4 structures of present use; It is just the same that this makes left and right halfbody to accomplish; Not only have one-time formed advantage, and a mould just can process two halfbodies, so greatly saved the production cost.Simultaneously, the structure after the improvement also have preparation process simple, after finishing machine finishing combination, precision is higher, more close-fitting, in light weight, produce more advantages such as fast and stable, integrity be better in batches.
Claims (2)
1. automobile-used combined piston; Comprise left halfbody (1) and right halfbody (2); Be respectively equipped with on the both ends of the surface of this left and right halfbody mounting hole (5) and a plurality of be the opening (3) that circumference uniform distribution is made in the center of circle with the mounting hole; The both ends of the surface of this left and right halfbody are equipped mutually to link into an integrated entity; And make corresponding connection of mounting hole (5) and opening (3) on the left and right halfbody, it is characterized in that the equipped mutually structure of described left and right halfbody (1,2) both ends of the surface is in the mounting hole (5) of left and right halfbody both ends of the surface, to be provided with the equipped fixed pin (4) in location, and through this fixed pin with an extrusion modling of left and right halfbody (1,2).
