Abstract
The utility model discloses an assembly and welding tooling for steel wires of a wire tube type evaporator. A framework is used as a main constructional element of the assembly welding tooling and is formed by two transverse frames and two longitudinal frames which are fixedly connected with one another, wherein a plurality of vertical straight flutes with upward openings are arranged on the longitudinal frames and are used for positioning workpiece metal tubes; more than two steel wire limiting bars are arranged in the framework, are fixedly connected at the inner sides of the longitudinal frames and are vertical to planes of the inner sides of the longitudinal frames; the plurality of vertical straight flutes with the upward openings are arranged on the steel wire limiting bars; the widths of the straight flues are larger than the diameters of steel wires, which is specified in a workpiece drawing; and the centre distance of each of the adjacent straight flutes is equal to the centre distance of each of the adjacent steel wires, which is specified in the workpiece drawing; and the assembly and welding tooling is provided with a pressing mechanism formed by a pressing bar and a threaded rod. When the assembly and welding tooling is used, the steel wires can be rapidly positioned through the steel wire limiting bars, the production efficiency is higher; and as the steel wire limiting bars are used for positioning, the assembly and welding accuracy of the wire tube type evaporator can be ensured.
Description
Technical field
The utility model relates to a kind of assembly welding frock, and more particularly, the utility model relates to a kind of wire-and-tube evaporator and uses the assembly welding frock.
Background technology
Wire-and-tube evaporator is formed by metal tube and steel wire assembly welding, and the frock that prior art is used for metal tube and steel wire assembly welding is the box shelf structure, is formed by fixedly connecting on two horizontal frames and two vertical frames; On vertical frame, be provided with the straight trough that a plurality of vertical direction, opening make progress; The location that is used for the workpiece metal pipe behind the workpiece metal pipe location, is placed on steel wire on the workpiece metal pipe; Behind the centering position, after pushing down steel wire, craft welds.This assembly welding tool structure is simple, is easy to realize, but has deficiency, and steel wire needs weld behind the centering, and time-consuming, bothersome, production efficiency is lower, and can't guarantee the positional precision between metal tube and the steel wire group.
The utility model content
The utility model provides a kind of wire-and-tube evaporator steel wire assembly welding frock that can realize fast that steel wire is located on metal tube to the deficiency of prior art, and this frock can guarantee the positional precision between steel wire and the metal tube.
The utility model is realized technical goal through following technical proposals.
Wire-and-tube evaporator steel wire assembly welding frock; It is main component with the framework; Said framework is formed by fixedly connecting on two horizontal frames and two vertical frames, on said vertical frame, is provided with the straight trough that a plurality of vertical direction, opening make progress, and is used for the location of workpiece metal pipe; Its improvements are: in said framework, be provided with two above steel wire positive stop strips; Said steel wire positive stop strip is fixedly connected on vertical scuncheon; Vertical with vertical scuncheon plane; On the steel wire positive stop strip, be provided with the upward opening straight trough of many vertical direction, the width of said straight trough is greater than the steel wire diameter of stipulating on the workpiece drawing, and the centre-to-centre spacing of adjacent straight trough equals the adjacent wires centre-to-centre spacing stipulated on the workpiece drawing; Be provided with press strip, screw rod and constitute hold-down mechanism, said screw rod is fixedly connected on two vertical frames, and press strip is across two vertical frames, and is sleeved on the screw rod.
In the said structure, the straight trough width is than the big 1～1.5mm of the steel wire diameter of stipulating on the workpiece drawing on the said steel wire positive stop strip.
The utility model compared with prior art has following good effect:
1. steel wire is fast located through the steel wire positive stop strip, and production efficiency is higher.
2. hold-down mechanism can guarantee between steel wire and the metal tube positioning accuracy in the welding process.
3. can guarantee the positional precision between welding back steel wire and the metal tube.

The specific embodiment
Below according to accompanying drawing and combine embodiment that the utility model is described further.
Wire-and-tube evaporator steel wire assembly welding frock shown in the drawings; It is a main component with framework 1; Framework 1 is formed by fixedly connecting on two horizontal frames 1.1 and two vertical frames 1.2, on vertical frame 1.2, is provided with the straight trough that a plurality of vertical direction, opening make progress, and is used for the location of workpiece 2 metal tubes; In framework 1, be provided with two steel wire positive stop strips 3; Steel wire positive stop strip 3 is fixedly connected on vertical frame 1.2 inboards; Vertical with vertical frame 1.2 inner side plane; On steel wire positive stop strip 3, be provided with the upward opening straight trough 3.1 of many vertical direction; The width of said straight trough 3.1 is greater than the steel wire diameter of stipulating on workpiece 2 drawings, and straight trough 3.1 width are than the big 1mm of steel wire diameter that stipulates on workpiece 2 drawings on the steel wire positive stop strip 3 in the present embodiment, and the centre-to-centre spacing of adjacent straight trough 3.1 equals the adjacent wires centre-to-centre spacing stipulated on workpiece 2 drawings; Be provided with press strip 4, screw rod 1.4 and constitute hold-down mechanisms, screw rod 1.4 is fixedly connected on two vertical frames 1.2, and press strip 4 is across two vertical frames 1.2, and is sleeved on the screw rod 1.4.
The utility model in use; After in workpiece 2 metal tubes being installed to vertical frame 1.2 straight troughs of the utility model, realizing the location of workpiece 2; Steel wire 2.1 is installed on the steel wire positive stop strip 3 in the straight trough 3.1, again press strip 4 is sleeved on the screw rod 1.4, compress press strip 4 through the nut on the screw rod 1.4; Press strip 4 is pressed in steel wire 2.1 on workpiece 2 metal tubes, can weld steel wire 2.1 and workpiece 2 metal tubes then.Steel wire 2.1 can be realized quick location through steel wire positive stop strip 3, and production efficiency is higher, and because steel wire positive stop strip 3 location are arranged, can guarantee wire-and-tube evaporator steel wire assembly welding precision.
