Abstract
The invention discloses a novel welding fixture of a wire tube evaporator. The novel welding fixture of the wire tube evaporator is characterized by comprising a base, stop dogs, self-locking bolts, pressure plates and comb-shaped bars, the base is of a rectangular frame structure, the stop dogs are symmetrically distributed on the two sides of the base, the self-locking bolts are fixed on the two sides of the base and connected with the stop dogs, the pressure plates are arranged on the upper end and the lower end of the base and used for fixing a wire tube, and the comb-shaped bars for fixing a steel wire are symmetrically distributed on the two sides of the frame center of the base. According to the the novel welding fixture of the wire tube evaporator, the defects of sticking welding and steel wire displacement in the prior art are overcome, the design is simple, the structure is reasonable, the welding fixture has the advantages that feeding is convenient, automatic loosing after clamping is achieved and the welding stability is good, and the welding fixture is suitable for continuous welding, batched production and use of wire tube evaporators.
Description
Technical field
The present invention relates to wire-tube evaporator welding tooling field, specifically belong to a kind of wire-tube evaporator Novel welding frock.
Background technology
Manufacture field at refrigeration industry evaporimeter, in the actual production process of wire-tube evaporator, need to be that 1.2mm ~ 2.0mm steel wire is firmly welded on by diameter, on the Bandaid steel pipe of diameter phi 7mm ~ φ 9.52mm.In this production process, require the positive and negative steel wire of wire-tube evaporator, symmetrical along steel pipe center line, the position, steel wire top on welding work pieces two opposite, outermost point does not exceed 3/4 of both sides outer diameter of steel pipes.Require to guarantee that actual production process environmental protection and economy is reliable and stable, the frock quality that welding process uses is light, and steel wire and block contact site insulate, and Wear-resistant, high-temperature resistant performance is good simultaneously.Consider above-mentioned factor, preferred option very ripe at present adopts " metal species fixing tool " for good.But metal species fixing tool conduct electricity, in rapid welding production process welding tooling very easily with Product jointing at one piece, cause product fraction defective and scrappage high, there is severe compromise simultaneously.For the problems referred to above, the invention provides a kind of wire-tube evaporator Novel welding frock.
Summary of the invention
The object of the invention is to provide a kind of wire-tube evaporator Novel welding frock, welding tooling adopts the comb shape bar structure of full symmetric, solve the problem of steel wire non complete symmetry in Product jointing process, simplicity of design, rational in infrastructure, by the nonmetallic materials using the light heat resistant and wear resistant of good insulating quality to damage, solve the problem that welding tooling and Product jointing stick together at a piece.
The technical solution adopted in the present invention is as follows:
A kind of wire-tube evaporator Novel welding frock, it is characterized in that comprising base, block, Bolt with latching action, pressing plate, comb shape bar, base is rectangular frame structure, base both sides are symmetrically distributed with block, Bolt with latching action is fixed on base both sides and is connected with block, be provided with pressing plate for fixing fiber tube at the two ends up and down of base, be distributed with the comb shape bar of fixing steel wire in bedframe center bilateral symmetry.
Described base material is albronze, and hardness is high, not easily deformation occurs during use, has uniform rectangular mounting hole, can fix comb shape bar in the both sides up and down of base.
Described Bolt with latching action is connected with block, is provided with SR at Bolt with latching action upper surface, and by SR after Bolt with latching action drives block locking to put in place, Bolt with latching action and block reset to slack position simultaneously, and block is made up of high-strength insulating electric bakelite.
Described pressing plate has two vertical U nibs, the distance on the left of left U-shaped hole and pressing plate is 30mm+0.1mm, and the distance on the right side of right U-shaped hole and pressing plate is 40mm+0.15mm.
Described comb shape bar is provided with multiple steel wire trough, and the number of teeth of steel wire trough is consistent with wire-tube evaporator steel wire weld quantity and weld spacing with spacing, and its degree of depth is 25mm+0.2mm, and each tooth has ramp down angle, and chamfer height is 2mm, and the angle at ramp down angle is 45 °.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention makes block by using the process for un-metal material that insulation high-temperature-resistant is wear-resisting, base is made by using albronze materials processing, size is carried out to relevant workpiece simultaneously, angle, the control of surface smoothness, makes this welding tooling have significant wearability, heat-resisting quantity and NA feature.In addition, solve the asymmetric problem of product steel wire positive and negative by comb shape bar structure, comb shape bar structure ensure that location and the positive and negative symmetry of steel wire in welding process, and left and right block prevents steel wire from moving left and right.Simultaneously this welding tooling have that material loading is convenient, self-relaxation and the good advantage of welding stability after clamping, be applicable to wire-tube evaporator continuous welding mass production and use.
