In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a car small-bore hollow square intraductal positioning mechanism that expands, includes square pipe, the tube seat has been seted up to the inside of square pipe, the inside of tube seat is provided with fixed voussoir, one side of fixed voussoir is equipped with taut voussoir, fixed voussoir with the both sides face of taut voussoir is provided with first heating panel, the bottom of fixed voussoir the top of taut voussoir is provided with the second heating panel.
Through the technical scheme: the tensioning wedge 1 is moved in the direction of the arrow in fig. 3, and the fixed wedge 2 and the tensioning wedge 1 are simultaneously moved in the direction of the arrow in fig. 2 by a wedge-like movement principle until the component is clamped.
As a further aspect of the present invention: and a welding seam is arranged between the inner side of the square pipe and the outer side of the fixed wedge block and the outer side of the tensioning wedge block.
Through the technical scheme: the deformation of the welding seam is small, and the size can be ensured.
As a further aspect of the present invention: bolts are arranged on the outer portion of the first heat dissipation plate and the upper portion of the second heat dissipation plate.
Through the technical scheme: the outer portion of the first heat dissipation plate and the second heat dissipation plate may be fixed by bolts.
As a further aspect of the present invention: the first heat dissipation plate and the second heat dissipation plate are made of softer copper materials.
Through the technical scheme: the heat at the welding seam is rapidly absorbed, the thermal deformation of the product is reduced, the replacement frequency of the first heat dissipation plate and the second heat dissipation plate is greatly reduced, and the maintenance cost is saved.
Compared with the prior art, the beneficial effects of the utility model are that:
this kind of car small-bore hollow square pipe internal expanding positioning mechanism, it has avoided the square hole internal diameter to accomplish can have the clearance with the locating piece after the tolerance, and the unable tight problem of clamp completely of product has reduced the maintenance cost simultaneously, and softer copper product material is chooseed for use to the material of first heating panel and second heating panel, and then reduces the product and warp, has reduced the change frequency of first heating panel and second heating panel, has practiced thrift the maintenance cost.

Detailed Description
The technical solutions in the embodiments of the present invention will be described and fully explained below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, in an embodiment of the present invention, an automobile small-bore hollow square tube internal expansion positioning mechanism includes a square tube 6, a tube slot 61 is opened inside the square tube 6, a fixed wedge 2 is provided inside the tube slot 61, a tensioning wedge 1 is assembled on one side of the fixed wedge 2, a first heat dissipation plate 3 is provided on two side surfaces of the fixed wedge 2 and the tensioning wedge 1, and a second heat dissipation plate 4 is provided above the tensioning wedge 1 at the bottom of the fixed wedge 2.
