The utility model is characterized in that the utility model also comprises a positioning shaft, a supporting seat, a chain plate, a handle, and a chain plate body, wherein, both ends of the chain plate are respectively connected with the positioning shaft and the handle by means of rivets and gaskets. The utility model is superior to combined pieces with standard structures in the same type, and therefore, the utility model has the advantages that the utility model can cooperate with standard elements of a combined clamp; the positioning is accurate; moreover, because the utility model is jointed through combined keys, the structure is reliable, and the assembly is convenient.

Description

Combination weldering tire hinge type holds out against the location component

The utility model relates to a kind of built-up jig class that makes up the weldering tire.

The at present domestic combination weldering tire that generally uses is that employing 12mm standard cell is a built-up jig basically, and its main purpose is in order to solve the problem of two aspects: the one, and the variation of supporting member space linear dimension; The 2nd, the variation of supporting member space angle.Yet this combination weldering tire also exists adjustability poor, loading and unloading difficulty, awkward shortcoming except volume is big.

The purpose of this utility model is to be on the basis of built-up jig kind selecting part 12mm standard cell for use, overcomes above shortcoming, according to the design feature and the requirement of combination weldering tire, provides a kind of simple in structure, easy to operate combination weldering tire hinge type to hold out against the location component.

The purpose of this utility model is achieved in that

A kind of combination weldering tire hinge type holds out against the location component and is made of rivet, packing ring and pin, it is characterized in that it also comprises locating shaft, bearing, carrier bar, handle and chain plate body, the two ends of wherein said carrier bar are connected with rivet, packing ring mode with handle with locating shaft respectively.The locating shaft front end has a screw, by the element or the sub-assembly of the replaceable different-diameter of this screw or other location structure, to adapt to the aperture on the various supporting members or the needs of project-welding nut vary in diameter.There is circular hole the bottom of bearing and plays the keyway of anastomosis, can make up by itself and round positioning disk, and then with bolt round positioning disk be strained on the supporting base of combination.During work, plate is moving backward with handle, and the drive carrier bar is done circular motion round pin, and it is the rectilinear motion that guiding is made advance and retreat with the bearing that the other end of carrier bar then drives locating shaft, locatees and hold out against purpose to realize unclamping.

The utility model is better than the similar component of normal structure, and it can be used with the standard component of built-up jig, accurate positioning, and because it is to connect by Macintosh, so reliable in structure, easy to assembly.

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further.

A kind of hinge type of the present utility model holds out against the location component, comprises locating shaft 1, bearing 2, rivet 3, packing ring 4, carrier bar 5, handle 6, chain plate body 7 and sells 8, and form by ordering assembly shown in Figure 1.The two ends of its intermediate plate 5 are connected with rivet 3, packing ring 4 modes with handle 6 with locating shaft 1 respectively.During work, plate is moving backward with handle 6, drives carrier bar 5 and does circular motion round pin 8, and it serves as the rectilinear motion that guiding is made advance and retreat with bearing 2 that the other end of carrier bar 5 then drives locating shaft 1, unclamps the location and holds out against purpose to reach.Position shown in Figure 1 is the dead-centre position, just holds out against the positioning action position.By the screw 9 replaceable different-diameters of locating shaft 1 front end or the element or the sub-assembly of other location structure, to adapt to the aperture on the various supporting members or the needs of project-welding nut vary in diameter.A cross keyway 10 and circular hole 11 are arranged at the bottom of bearing 2, can make up by itself and round positioning disk, and then with bolt round positioning disk be strained on the supporting base of combination.This combination can realize that the utility model is in 360 ° of rotations of horizontal level do, to adapt to the needs of angle location.

Therefore this component also can satisfy the bicycle frame pipe and the variation of supporting member angle of tilting owing to increased adjustable, interchangeable special purpose parts.The use of special purpose parts makes the weldering tire easy to assembly quick.
