Description

Butt-welding machine

Technical field

This utility model relates to a kind of welding equipment, particularly to a kind of butt-welding machine.

Background technology

The structure being designed with thin rod shape of a lot of modern furnitures is as support section, and in order to alleviate furniture weight, reduce material, the structure of these thin rod shapes often uses hollow pipe to be processed into, and uses hollow pipe that the processing and fabricating of furniture can be made the most succinctly to facilitate.But these furniture are applied workpiece tube need its port is shut.Complete this work at present and rely primarily on manual method, the board-like material of the port of closed work piece pipe is cut into the mounting similar to port size, shape, mounting is placed on the port of workpiece tube, rely on and manual the two is carried out welding welding.

So relying on the workpiece tube of artificial method output, process velocity speed is slow, it is difficult to adapting to large-scale production, the port weld seam of workpiece tube is irregular, and difficult quality keeps consistent, and the workload using later stage polishing and the polish needed as furniture is heavy.

Utility model content

The purpose of this utility model is to provide a kind of butt-welding machine that can quickly, neatly complete workpiece tube end seals.

Above-mentioned technical purpose of the present utility model has the technical scheme that

A kind of butt-welding machine, including transformator, clamping device affixed on workbench and workbench, transformator connects the first electrode and the second electrode, clamping device includes lower clamp, it is positioned at the upper fixture above lower clamp and drives above fixture to move downwards thus clamp the driver of workpiece, when clamp position, it is formed with holding tank between upper fixture and lower clamp, mounting fixture it is provided with on work platforms, it is provided with on mounting fixture and coordinates clamping part with mounting, retaining part is on the bearing of trend of holding tank, first electrode and the second electrode connect with lower clamp and mounting fixture respectively.

It is also preferred that the left the clamping part of mounting fixture is draw-in groove, holding tank includes being opened in the upper holding tank on holder surface and being opened in the lower holding tank of lower clamp clamping surface.

By above technical scheme, traditional clamping is replaced with draw-in groove, decrease the space on the shared mounting of clamping, use the method to set up of above-mentioned mounting fixture and lower holding tank, ensure that the center with workpiece, the mounting center is to it, therefore can use and weld with workpiece port size, mounting that shape is consistent, reduce post-production surplus further, reduce later stage polishing, the workload of polish.

It is also preferred that the left the cross section of draw-in groove and lower holding tank is in the shape of the letter V, the cross section of upper holding tank is inverted v-shaped.

By above technical scheme, draw-in groove, lower holding tank have rectangular clamping face, are adapted to circle or the welding of square workpiece of all size, expand the usage range of fixture, are that butt-welding machine has more application space.

It is also preferred that the left holding tank tilts, and slot sets low in holding tank.

By above technical scheme, mounting is affected by gravity in draw-in groove, fall draw-in groove side surface, it is ensured that in the case of without actively clamping, mounting is in steady statue in draw-in groove, it is ensured that the stability of draw-in groove clamping.

It is also preferred that the left worktable upper surface tilts, upper fixture lower surface is parallel with workbench, and driver is vertically placed.

By above technical scheme, in the case of ensureing without actively clamping, while mounting is in steady statue in draw-in groove, it is ensured that driving means will not affect the life-span of driving means because tilting to be affected by gravity.

It is also preferred that the left table surface is connected with postive stop baffle.

By above technical scheme, it is ensured that in the case of table surface tilts, providing extra for each several part assembly on workbench and support, thus reduce workbench and the stress on the connector of each several part assembly, butt-welding machine is more stable.

It is also preferred that the left worktable upper surface is connected with pressurized cylinder, the piston rod of pressurized cylinder is fixed on the mounting fixture face away from clamping device end.

By above technical scheme, promote mounting fixture close to lower clamp, make mounting and Workpiece clamping, be that welding effect is more guaranteed.

It is also preferred that the left mounting fixture has line slide rail, mounting fixture is slidably connected with line slide rail, and line slide rail is fixed in table surface.

By above technical scheme, line slide rail is set below mounting fixture, makes the action that steps up between mounting and workpiece complete on line slide rail, provide support for mounting fixture, reduce the stress of pneumatic cylinder, and mounting fixture sliding is stable.

It is also preferred that the left worktable upper surface is detachably fixed connection mounting receiver.

By above technical scheme, mounting is square tagger, has sharp comer, arbitrarily places the personnel that easily cause and accidentally injures, arranges receiver, it is ensured that the safety of staff, is that work top is the cleanest and the tidiest in order simultaneously.

In sum, this utility model has the advantages that

In the environment of can be implemented in clean and tidy, safety, the mounting of application minimum area, quickly, neatly, safely and effectively to the port of the workpiece of variously-shaped, size shut.Can ensure that the quality of weld seam and the succinct of welding process simultaneously.
