Abstract
The utility model discloses an online monitoring device for continuous welding area, which can automatically observe very subtle changes in welding area thus reducing labor intensity and improving quality of products. The monitoring device comprises an observation window which is arranged on a welding protective cover, a color video camera which is installed opposite to the observation window and optical filtering lens which is arranged in front of the lens of the color video camera; output signals of the color video camera are formed into an image and displayed by a color display device. The monitoring device is mainly used for observing the welding area in the edge joint process while welding metal tubes.
Description
Technical field
The utility model relates in the piece process of weld metal pipe, observes the monitoring arrangement of the welding situation of weld zone.
Background technology
As everyone knows, most of metal tubes all be with metallic plate after curl being shaped through driven roller, between the welding compression roller, its piece is welded.In order clearly to observe the welding situation of weld zone, the observer observes by the protective cover that is provided with the colour filter observation window.Because the resolution of people's naked eyes is limited, can't observe the slight change of weld zone, also just can't makes adjustment in time, thereby have influence on the quality of product welding torch; And the observation personnel keep a posture for a long time, and labour intensity is big, be easy to make the people to produce fatigue, cause absent mindedly, make many unusual conditions of weld zone not be caught in, do not adjust thereby welding torch is made in time, have influence on the quality of product.
The utility model content
Technical problem to be solved in the utility model is: thus provide a kind of very trickle variation that can observe the weld zone automatically can reduce labour intensity and the monitoring arrangement of the on-line continuous weld zone that improves the quality of products.
Further technical problem to be solved in the utility model is: a kind of monitoring arrangement that can protect colour TV camera well is provided.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: the monitoring arrangement of on-line continuous weld zone; comprise: be arranged on the observation window on the welding protection cover; be provided with colour TV camera facing to observation window; be provided with the optically filtering camera lens before the camera lens of colour TV camera, the output signal of colour TV camera is shown by the color monitor imaging.
For solving above-mentioned further technical problem; the technical solution adopted in the utility model is: above-mentioned colour TV camera and optically filtering camera lens are arranged in the protection tube that offers air inlet, and the end wall of protection tube is provided with and the corresponding peephole of optically filtering camera lens.
Be provided with secondary light source in the above-mentioned welding protection cover.
The beneficial effects of the utility model are: owing to adopted colour TV camera continuously the weld zone to be carried out automatic camera, and with colour TV camera take the photograph image show by the color monitor imaging, thereby greatly reduce observer's labour intensity; And the resolution of colour TV camera is very high, and can on color monitor, will take the photograph image amplify, making that the observer can observe naked eyes can not observed slight change, adjusts so that welding torch made in time, improves the quality of product.In addition, being provided with of protection tube can avoid dust to enter colour TV camera, but also can feed coolant in the protection tube, to prevent that the weld zone is constantly to the vehement colour TV camera of hindering of extraradial heat.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1; the monitoring arrangement of on-line continuous described in the utility model weld zone; comprise: be arranged on the observation window 9 on the welding protection cover 8; installing rack 1 is provided with colour TV camera 5; the camera lens of colour TV camera 5 is facing to observation window 9; be provided with the optically filtering camera lens 4 of the high light that produces when being used for the elimination welding before the camera lens of colour TV camera 5, the output signal of colour TV camera 5 is connected by the input of output line 6 with color monitor 7.In the present embodiment, described colour TV camera 5 and optically filtering camera lens 4 are arranged in the protection tube 3 that offers air inlet 2, the end wall of protection tube 3 is provided with and optically filtering camera lens 4 corresponding peepholes, the protection tube 3 has here adopted stainless steel material, has good corrosion-resistant and high temperature resistant property, and can in protection tube 3, constantly inject coolant by air inlet 2, coolant flows out from peephole carry out exchange heat in protection tube 3 after---and peephole just becomes the outlet of coolant like this, filling with under the situation of coolant, protection tube 3 can anti-high temperature more than 1000 ℃, because colour TV camera 5 has adopted the pin-hole imaging technology, make the aperture of described peephole only be 0.5mm, dust can not enter in the protection tube 3, thereby colour TV camera 5 and optically filtering camera lens 4 are played a very good protection; In order when not welding, to see the situation of weld zone clearly,, in described welding protection cover 8, be provided with secondary light source 11 to make things convenient for the adjusting of colour TV camera 5 and welding torch 12.
The course of work that metal tube piece welder of the present utility model is installed is: before welding, at first open secondary light source 11, adjust the position of welding torch 12 and colour TV camera 5, make the camera lens of colour TV camera 5 face the weld zone; Energized, whole metal tube piece welder is started working, workpiece 16 passes through shaping driven roller 15 continuously, strip metal plate when entering crossfades into the metal tube of long and narrow piece together that contains of tubular, and between two bond pads compression rollers 14, weld by the piece of 12 pairs of workpiece 16 of welding torch, make it to become the metal tube of sealing; In the continuous welding process, color video camera 5 carries out automatic camera to the weld zone always continuously, and will take the photograph image deliver to color monitor 7 by output line 6 and amplify demonstration, thereby greatly reduce observer's labour intensity; And the resolution of colour TV camera 5 is very high, and can on color monitor 7, will take the photograph image amplify, making that the observer can observe naked eyes can not observed slight change, adjusts so that welding torch 12 made in time, improves the quality of product.In addition, being provided with of protection tube 3 can avoid dust to enter colour TV camera 5, but also can feed coolant in protection tube 3, to prevent that the weld zone is constantly to the vehement colour TV camera 5 of hindering of extraradial heat.
