[0002] The magnetic float level gauge is based on the principle of buoyancy and magnetic coupling. The magnetic float floats up and down in the measured medium as the liquid level changes.

Operate the drive slider to move the cylinder, so as to adjust the distance between the cylinder and the welding equipment, and to perform welding at different positions on the cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) Start the rotating motor so that its output end drives the driving wheel to rotate, and several driving wheels rotate in the same direction. Under the action force, the cylinder in contact with the driving wheel is driven to move, so that it moves on the supporting circular wheel. Several supporting circular wheels guide the movement of the cylinder, and at the same time, the supporting circular wheel is in a rotating state, which reduces the resistance encountered by the cylinder when it moves and improves the stability of the cylinder when it moves, so that the cylinder can continue to move after being clamped to adjust the welding position of the cylinder, so that the device can continue to adjust the distance between the cylinder and the welding equipment, avoiding the distance between the two being fixed and unable to be adjusted during welding, resulting in the need for manual operation by the operator, avoiding excessive contact between the operator and the welding equipment and raw materials during welding, resulting in safety risks, reducing the limitations of the device during use, and improving the welding effect of the device; at the same time, the friction between the driving wheel and the cylinder is increased by the rubber ring, avoiding the inability of the driving wheel to drive the cylinder to move due to insufficient friction when rotating, thereby improving the use effect of the device; (2) The reciprocating cross plate moves back and forth, and under the action of the elastic square rod, the buffer pad is driven to move back and forth, so that it is constantly in contact with the cylinder to monitor the movement state of the cylinder. When the movement state of the cylinder is normal, the deformation amount generated by the buffer pad each time it contacts the cylinder is consistent. When the movement state of the cylinder deviates, such as offset, the deformation amount of the buffer pad will be different, indicating that the movement of the cylinder has deviated. The built-in signal device sends a signal to the controller to remind the operator to avoid welding problems of the device and prevent the cylinder from dislocating during movement, thereby improving the welding accuracy of the device and further improving the welding effect of the device. It is worth mentioning that when the reciprocating cross plate moves toward the direction of the cylinder, the buffer pad is driven to move under the action of the elastic square rod, so that several trigger wheels are in contact with the side wall of the cylinder, avoiding excessive resistance when the buffer pad contacts the cylinder to affect the normal movement of the cylinder, improving the stability of the cylinder during movement, and further reducing the limitations of the device during use; (3) The displacement cross block moves in the limit slot through the limit block, thereby driving the forked square rod to move. Since the threads of the two displacement screws are opposite, the forked square rods on both sides of the workbench move toward each other, so that the auxiliary cross plates on both sides of the cylinder move toward the direction of the cylinder. Under the action of the auxiliary cylinder and the auxiliary spring, the arc plate is driven to move so that its inner wall fits with the cylinder, thereby clamping the placed cylinder to avoid its movement due to non-human factors during the welding process, which affects the welding effect and improves the welding efficiency of the device. The lubrication pad on the inner wall of the arc plate is in contact with the cylinder. After the cylinder is clamped, the friction between the arc plate and the cylinder is prevented from being too large to affect the movement of the cylinder, and the resistance encountered when the cylinder moves is reduced. At the same time, the clamping of the cylinder is not affected during the movement, and the cylinder is prevented from being dislocated when clamped. At the same time, the auxiliary horizontal plate continues to be moved to move within the upper limit of the auxiliary cylinder, so that the auxiliary spring is in a buffer state, which strengthens the contact strength between the arc plate and the cylinder, and further improves the clamping effect and strength of the device. (4) When the fitting lock contact unit clamps the cylinder, the auxiliary horizontal plate moves, and the driving square column and the driving spring drive the driving U seat to move, so that the driving wheel moves. It is worth mentioning that the driving wheel contacts the cylinder earlier than the arc plate, so that the driving wheels on both sides of the workbench contact the side wall of the cylinder placed on the supporting round wheels, thereby initially limiting the cylinder to avoid the position of the cylinder being offset due to non-human factors during the clamping process, improving the clamping accuracy of the device, avoiding the deviation of the clamping position affecting the welding operation of the device, improving the accuracy of the device during welding, and further reducing the limitations of the device during use. At the same time, by continuing to move the auxiliary horizontal plate, the driving cross block moves within the upper limit of the driving square column, and the driving spring is in a buffering state, which strengthens the contact strength and friction between the driving wheels and the side wall of the cylinder, so that the effect of the device during use is also improved; (5) Start the linkage motor so that its output end drives the linkage gear to rotate, thereby engaging the linkage gear ring to rotate, so that it rotates in the guide ring groove through the guide ring block, thereby driving the welding equipment to rotate under the action of the extension frame, limiting the rotation of the welding equipment, avoiding the phenomenon of shaking of the welding equipment during rotation, and improving the stability of the welding equipment during rotation, so that the welding equipment rotates around the welding position of the cylinder, continuously adjusting the welding position, avoiding the need for the operator to frequently adjust the welding position, improving the welding efficiency of the device, and ensuring the safety of the device during use. The cylinder can be welded at multiple positions, reducing the limitations of the device during use, avoiding the limitations being too large to affect the normal use of the device, so that the welding effect of the device is improved; it is worth mentioning that through the provision of several air ducts, the waste gas, toxic gas and other polluted gases generated by the device during welding can be guided to other areas, avoiding the accumulation of waste gas, toxic gas and other polluted gases at the welding position of the cylinder to affect the operator or the device, thereby improving the safety of the device during use. At the same time, a filtering device can be provided to reduce the pollution generated by the device during welding, so that the device can be adjusted when welding the cylinder without affecting the body of the staff, further improving the use effect of the device.
