[0003] During the production process of the can, it is necessary to install a bracket on its surface, so it needs to be fixed by a positioning device, and then the bracket is installed. However, at present, the can needs to be installed with brackets at different angles. Therefore, the traditional fixing method requires manual frequent replacement of the fixing angle of the can, which is more troublesome. Moreover, when fixing, the protective gas injected into the can cannot be discharged, so that the heat cannot be effectively dissipated. This can easily cause the internal temperature to be too high when the welding temperature rises, which brings danger and deformation.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a positioning device based on tank welding. Utility Model Content

[0010] Preferably, a screw transmission assembly B for driving the bracket fixing platform to move back and forth is installed on the top of the welding platform opposite to the outer wall of the sealing tank, which is more convenient for the staff to operate.

[0011] Preferably, universal wheels with locking function are provided around the bottom of the welding platform to facilitate the movement of the device.

[0012] Preferably, a rotation control device is installed on the motor to accurately control the angle at which the motor drives the tank to rotate.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model first inserts the open end of the can into the support part on the annular body when installing it, and then drives the nylon limiting block to move in the direction of the motor through the screw transmission component A, pushes the can to the specified position, and then fixes it through the pressing component to achieve the fixation of the can. After the fixation is completed, the annular body can be driven by the motor to rotate, the annular body drives the can to rotate, and the can drives the nylon limiting block to rotate, so as to adjust the angle of the can, so as to install the bracket at different angles, and the operation is simpler.

[0021] 2. When the motor drives the tank to rotate, the high-precision sensor in the utility model can monitor the rotation angle of the motor in real time and transmit a signal to the controller. The controller processes the signal sent by the high-precision sensor, and then sends a corresponding signal to the actuator. The actuator controls the operating state of the precision reducer according to the signal of the controller, so that the precision reducer can accurately control the speed of the motor and stop at a suitable angle. Through the cooperation of the above-mentioned components, the motor control rotation accuracy can reach arc minutes, which greatly reduces the probability of producing scrap due to inaccurate angle positioning.

DETAILED DESCRIPTION

[0029] When installing the stuffing can 8, first insert its open end into the support part 31 on the annular body 3, then drive the nylon limiting block 4 to move toward the motor 2 through the screw transmission assembly A5, push the stuffing can 8 to the specified position, and then fix it through the pressing component 7 to achieve the fixation of the stuffing can. It should be noted that the nylon limiting block 4 includes three blocks 41 distributed in a circular array, which are designed to correspond to the curvature of one side of the stuffing can 8 and can fit tightly with the stuffing can 8. After the fixation is completed, the annular body 3 can be driven to rotate by the motor 2. The annular body 3 drives the rotation of the stuffy tank 8, and the stuffy tank 8 drives the rotation of the nylon limiting block 4, so as to adjust the angle of the stuffy tank 8, so as to install the bracket at different angles, which is simpler to operate. At the same time, the overall positioning of the stuffy tank adopts segmented contact of the circular shaft, which is fixed and stable. Therefore, on the basis of ensuring that it does not deform, the argon gas filled in the inside of the stuffy tank can be discharged through the exhaust hole, which promotes the circulation of argon gas and thus dissipates heat, preventing oxidation inside the weld (argon gas is continuously added) and avoiding the danger and deformation caused by excessive temperature inside the stuffy tank 8 due to the heating of welding.

[0030] There are three clamping components 7 distributed in a circular array on the annular body 3, which include a connecting plate 71 fixed on the outer wall of the annular body 3, the internal thread of the connecting plate 71 is connected to a screw 72, and the bottom of the screw 72 is rotatably connected to a pressure block 73, and the surface of the pressure block 73 is tightly fitted with the surface of the annular body 3 to prevent the pressure block 73 from rotating, that is, when the screw 72 is rotated clockwise, the screw 72 moves along the connecting plate 71, and at the same time, the screw 72 drives the movement of the pressure block 73, so that the three pressure blocks 73 press the outer wall of the sealing tank 8, thereby completing the fixation of the sealing tank 8.

[0031] In addition, a rotation control device 6 is installed on the motor 2 to accurately control the rotation angle of the tank 8 driven by the motor 2. The rotation control device 6 shares a power supply with the motor 2, and is composed of a high-precision sensor, a controller, an actuator and a precision reducer. When the motor 2 drives the tank 8 to rotate, the high-precision sensor can monitor the rotation angle of the motor 2 in real time and transmit a signal to the controller. The controller processes the signal sent by the high-precision sensor, and then sends a corresponding signal to the actuator. The actuator controls the operating state of the precision reducer according to the signal of the controller, so that the precision reducer accurately controls the speed of the motor 2, thereby stopping at a suitable angle. Through the cooperation of the above-mentioned components, the rotation control accuracy of the motor 2 can reach three arc minutes, which greatly reduces the probability of producing scrap due to inaccurate angle positioning.

[0032] Furthermore, a screw transmission assembly B11 for driving the bracket fixing platform 10 to move back and forth is installed on the top of the welding platform 1 opposite to the outer wall of the sealing tank 8, that is, the bracket can be fixed by supporting the fixing platform. After the angle adjustment of the sealing tank 8 is completed, the bracket is pressed against the welding platform 1 through the screw transmission assembly B11 for welding, which is more convenient for the staff to operate, and universal wheels 12 with locking function are provided around the bottom of the welding platform 1, making the device more convenient to move.
