Description
Technical Field
The invention belongs to the technical field of welding wire feeding devices, and particularly relates to a device for measuring the welding wire allowance in a vacuum argon filling cabin.
Background
Titanium is an active metal element, so that the titanium is very easy to be polluted by impurities such as oxygen, nitrogen and the like in the air at high temperature, and the embrittlement degree is serious. The prior titanium alloy components, whether welding or material adding, must be performed in a vacuum argon-filled environment. For some large rice-grade structures, large vacuum equipment is required, which can lead to an internal situation that is not apparent when working.
Because the vacuum cabin environment limits, the required cost of each processing operation is higher, if the wire feeding process has problems, the problem that the welding wires are exploded can not be effectively solved, and the welding wires can only be coiled again through the cabin door, so that the device can improve the problems and prevent the probability of occurrence of the conditions when the construction period and the cost float greatly.
Because of the environmental limitation of the vacuum cabin, the allowance problem has a great influence on the construction period and the working hours in actual operation, and the unexpected arc breakage can have a great influence on the performance and the forming of the component for important parts of the component, and the post-processing is inconvenient. What is needed is an apparatus for determining wire remaining.
Disclosure of Invention
In view of the above, the invention aims to provide a measuring device suitable for the welding wire allowance in a vacuum argon filling cabin, so as to solve the problem that the existing welding wire allowance and welding wire explosion cannot be accurately judged.
In order to achieve the above purpose, the technical scheme of the invention is realized as follows:
The vacuum argon filling room is required to be subjected to vacuum argon filling, the residual quantity of the residual welding wire cannot be judged in the material adding process, and the residual welding wire cannot be replaced in time, so that the material adding task is required to be completed as much as possible because the cost of manpower and material resources required for carrying out vacuum argon filling once is not very high, the cabin door cannot be opened at will, the room is completely sealed, the problem of light rays is solved, people cannot observe clear welding wire residual quantity outside, a welding wire residual quantity measuring device is required, the residual quantity of the welding wire can be determined, an alarm is given when the residual quantity is less than a certain quantity, and the problem in the continuous material adding process is avoided.

Further, the electric signals generated by the temperature sensor and the pressure sensor penetrate into the two through round holes on the main shaft from the hollow structure of the bolt through the lead. The sensor needs to be provided with a temperature sensor for measuring the temperature of the circular arc-shaped thin plate because a large amount of heat is easily generated due to friction generated with the thin plate by the high-speed rotation of the wire reel during wire feeding.
Further, an arc-shaped thin plate is used for being attached to the inner wall of the wire reel, and the arc-shaped thin plate is made of alumina ceramic material.
Furthermore, the arc-shaped thin plate is in threaded connection with the heat-resistant high-elasticity stud, so that the heat-resistant high-elasticity stud is easy to replace. For circular arc alumina ceramic sheets, replaceable type is used to connect to the sensor, as there is wear and tear that requires periodic replacement.
Further, the wire adopts an explosion-proof wire. The monitoring device is provided with warning data values, and when the temperature is higher than a certain degree centigrade or the weight is lower than a certain warning value, red warning is automatically sent out in the display screen. The wires connected with the sensor and the data acquisition system need to be wrapped by explosion-proof pipes, and therefore the wires need to be protected under the vacuum condition to ensure that the device can be used normally.
According to the aluminum oxide ceramic thin plate arranged on the sensor, the aluminum oxide ceramic thin plate is designed into an arc shape, so that the contact area between the inner wall of the wire reel and the thin plate can be increased slightly, friction can not be increased, the wire reel cannot rotate smoothly, the wire reel cannot excessively rotate when wire feeding is stopped, and wire explosion can be effectively prevented.
