The piston-sleeve shaping device comprises a box body with a rectangular section, wherein a first clamping block, a second clamping block, a third clamping block and a fourth clamping block are arranged inside the box body, are in butt connection with one another and enable a piston sleeve to be tightly clamped inside the box body, the clamping blocks are provided with grooves used for containing connection pipes which comprise opposite pipes and horizontal pipes, the center lines of the grooves are coplanar, and a first wedge and a second wedge which are used for enabling the clamping block to be tightened are further arranged between the clamping blocks and the inner wall of the box body. The piston-sleeve shaping device is simple in structure, the clamping blocks wrap the piston sleeve, and the connection pipes which comprise the opposite pipes and the horizontal pipes can be adjusted in position by making the clamping blocks get close and be tightly attached to one another through the first wedge and the second wedge, and the piston-sleeve shaping device is easy to operate and good in shaping effect.

Description

Piston jacket apparatus for shaping

Technical field

The utility model belongs to machining equipment technical field, relates in particular to a kind of piston jacket apparatus for shaping.

Background technology

Fig. 1 has shown the top view structure of the piston jacket that is installed on circular horn, can find out the overcoat body 2 that it comprises the tubular that is positioned at center, is connected with a plurality of tube connectors that communicate with inner chamber on its sidewall, needs to place piston core in inner chamber.Tube connector generally divides two groups, and one group is to managing 1, and other one group is flat pipe 3.On concrete structure, to managing 1 two tube connectors that comprise, be oppositely arranged, flat pipe 3 two tube connectors that comprise are horizontally disposed with.For the needs of assembling, to managing 1 center line, need strict coplanar with the center line of flat pipe 3.Due to each tube connector, to be welding affixed, therefore be difficult to guarantee above-mentioned position relationship, before the integral body assembling of carrying out circular horn, needs to carry out shaping for piston jacket.

Utility model content

The utility model provides a kind of piston jacket apparatus for shaping of simple in structure, simple operation for solving the technical problem existing in known technology.

The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: piston jacket apparatus for shaping comprises the box body of square-section, is provided with mutual docking and piston jacket is clamped in to inner the first fixture block, the second fixture block, the 3rd fixture block and the 4th fixture block in described box body; Described the first fixture block comprises that two contact with the inwall of box body and mutually perpendicular sidewall, are respectively equipped with the accommodating groove to a tube connector of the groove of pipe tube connector and accommodating flat pipe on two other sidewall; Described the second fixture block, between the first fixture block and the 3rd fixture block, has a sidewall contacting with the inwall of box body, on adjacent two sidewalls of this sidewall, is respectively equipped with the accommodating groove to two tube connectors of pipe; Described the 3rd fixture block comprises two mutually perpendicular sidewalls, one of them sidewall contacts with the inwall of box body, between another sidewall and the inwall of box body, be provided with the first sphenoid, on two other sidewall, be respectively equipped with the accommodating groove to another root tube connector of the groove of another root tube connector of pipe and accommodating flat pipe; A sidewall of described the 4th fixture block is provided with the groove of two tube connectors of accommodating flat pipe, between the sidewall relative with this sidewall and the inwall of box body, is provided with the second sphenoid; The center line of above-mentioned each groove is coplanar.

Advantage of the present utility model and good effect are: apparatus for shaping of the present utility model is simple in structure, each fixture block is coated on the outside of piston jacket, by the first sphenoid and the second sphenoid, force each fixture block near being adjacent to, to i.e. adjusted the putting in place of each tube connector of managing peaceful pipe, simple to operate, shaping effect good.

The specific embodiment

For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:

Refer to Fig. 2 and Fig. 3, the utility model comprises the box body 10 of square-section, in box body 10, be provided with mutual docking and piston jacket is clamped in to inner the first fixture block 4, the second fixture block 5, the 3rd fixture block 6 and the 4th fixture block 8, the above-mentioned first, second, third and the 4th only for the differentiation of parts, and does not represent erection sequence and annexation.

The first fixture block 4 comprises that two contact with the inwall of box body 10 and mutually perpendicular sidewall, is respectively equipped with accommodating to managing 1 the groove of a tube connector and the groove of a tube connector of accommodating flat pipe 3 on two other sidewall.

The second fixture block 5, between the first fixture block 4 and the 3rd fixture block 6, has a sidewall contacting with the inwall of box body 10, is respectively equipped with accommodating to managing the groove of 1 two tube connectors on adjacent two sidewalls of this sidewall.

The 3rd fixture block 6 comprises two mutually perpendicular sidewalls, one of them sidewall contacts with the inwall of box body 10, between the inwall of another sidewall and box body 10, be provided with the first sphenoid 7, on two other sidewall, be respectively equipped with accommodating to managing 1 the groove of another root tube connector and the groove of another root tube connector of accommodating flat pipe 3.

A sidewall of the 4th fixture block 8 is provided with the groove of two tube connectors of accommodating flat pipe 3, between the sidewall relative with this sidewall and the inwall of box body 10, is provided with the second sphenoid 9.
