Abstract
The invention discloses a positive and negative assembly welding clamping fixture for an aluminum alloy roof of car and is characterized in that the invention is provided with a plurality of positive and negative assembly conversion clamping fixture units driven by a connecting rod for a cylinder link gear; the positive and negative assembly conversion clamping fixture units includes a rotating shaft, a positioning supporting plate, a rotor sleeved on the rotating shaft, and a positive clamping fixture plate and a negative clamping fixture plate fixed on the rotor; the positive clamping fixture plate and negative clamping fixture plate are vertical to each other and parallel with the rotating shaft. Welding craft equipment is designed with a plurality of the positive and negative assembly conversion welding clamping fixture units, namely the positive and negative surfaces of the craft equipment consists of the positive clamping fixture plates and the negative clamping fixture plates of the clamping fixture respectively and converses the positive clamping fixture plates and the negative clamping fixture plates of the clamping fixture through a cylinder interlock mechanism in turn. The invention finishes the positive and negative clamping compound welding on the welding of units in turn through the cylinder link gear. The positive and negative assembly welding of aluminum alloy roof of the car are completed by one set of craft equipment, thus saving the cost of the craft equipment cost, reducing the cost, occupying few a manufacture state for an automatic welding machine and improving the manufacture efficiency.
Description
Technical field
The present invention relates to a kind of passenger train aluminum alloy roof plate assembly welding frock, particularly a kind of passenger carriage aluminum alloy roof plate positive and negative group welding clamping fixture.
Background technology
The production of aluminium alloy roof parts need be carried out the welding of the positive and negative two sides of top board workpiece, and frock needs workpiece location and clamping during positive and negative welding.This type of frock comprised two cover molds in the past, and promptly each cover of front welding positioner and reverse side welding positioner all is placed on automatic welder(welding machine) and produces on the platform position, in the assembly welding process, uses successively.The shortcoming of its existence is, the frock input is many, need account for automatic welder(welding machine) more and produce the platform position, and cost height not only, and also production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming that prior art needs two cover molds, and a kind of passenger carriage aluminum alloy roof plate positive and negative group welding clamping fixture is provided.
The technical solution adopted for the present invention to solve the technical problems is following: a kind of passenger carriage aluminum alloy roof plate positive and negative group welding clamping fixture; It is characterized in that having some positive and negative tire conversion mold unit by the connecting rod drive of cylinder linkage mechanism; Described positive and negative tire conversion mold unit comprises turning cylinder, positioning support seat, be enclosed within rotor on the turning cylinder, be fixed on the positive tire plate on the rotor, anti-tire plate, and described positive tire plate, anti-tire plate are vertical and parallel with turning cylinder each other.
Beneficial effect of the present invention is following: welding tooling has designed the convertible mold of some positive and negative tires unit; The positive and negative tyre surface that is frock is combined by the positive tire plate of mold unit, anti-tire plate respectively, is in anti-dress tire state through cylinder linkage mechanism by frock earlier, and this moment, the anti-tire plate of each mold unit was in state vertically upward; And positive tire plate is in level below anti-tire plate; Top board workpiece (through crane) drops on anti-assembling the on the frock, and automatic welder(welding machine) carries out the welding of reverse side weld seam to workpiece, treats workpiece reverse side welding completion; Through cylinder linkage mechanism frock is transformed into formal dress tire state again; This moment, the positive tire plate of each mold unit was in state vertically upward, and anti-tire plate is in level below positive tire plate, and top board workpiece (through crane) drops on just to be assembled on the frock; Automatic welder(welding machine) carries out the fillet in normal shear welding to workpiece, accomplishes the positive and negative group welding of top board workpiece.By the positive and negative group welding of a cover frock completion passenger carriage aluminum alloy roof plate, practice thrift the frock expense, reduce cost, account for automatic welder(welding machine) less and produce the platform position, enhance productivity.

The specific embodiment
With reference to the accompanying drawings and combine instance that the present invention is described in further detail.But the invention is not restricted to given example.
Like Fig. 1, Fig. 4, shown in Figure 5; Passenger carriage aluminum alloy roof plate positive and negative group welding clamping fixture of the present invention; Has some positive and negative tire conversion mold unit by connecting rod 61 drives of cylinder linkage mechanism 6; Described positive and negative tire conversion mold unit comprises turning cylinder 2, positioning support seat 7, be enclosed within square column type rotor 3 on the turning cylinder 2, be fixed on positive tire plate 4, anti-tire plate 1 in the slot 34,31 of rotor 3, and described positive tire plate 4, anti-tire plate 1 are vertical and parallel with turning cylinder 2 each other.
As shown in Figure 2, top board workpiece 5 is anti-assembling on anti-tire plate 1, is convenient to the reverse side of workpiece 5 is welded.
As shown in Figure 3, top board workpiece 5 is just assembled on positive tire plate 4, is convenient to the front of workpiece 5 is welded.
As shown in Figure 4, cylinder linkage mechanism 6 lets frock be in anti-dress tire state through connecting rod 61, makes the mold cell location with positioning support seat 7; This moment, the anti-tire plate 1 of each mold unit was in state vertically upward; And positive tire plate 4 is in level below anti-tire plate 1, and top board workpiece (through crane) drops on anti-assembling the on the frock, and automatic welder(welding machine) carries out the welding of reverse side weld seam to workpiece; In this process, positive tire plate 4 does not contact with workpiece.
As shown in Figure 5, cylinder linkage mechanism 6 lets frock be in formal dress tire state through connecting rod 61, makes the mold cell location with positioning support seat 7; This moment, the positive tire plate 4 of each mold unit was in state vertically upward; And anti-tire plate 1 is in level below positive tire plate 4, and top board workpiece (through crane) drops on just to be assembled on the frock, and automatic welder(welding machine) carries out the fillet in normal shear welding to workpiece; In this process, anti-tire plate 1 does not contact with workpiece.
Among the embodiment, confirm the quantity of mold unit according to the length of top board workpiece, feasible data are following: the thickness of positive and negative tire plate is 8 millimeters, and the distance between the mold unit is 800 millimeters.
