Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the utility model.

The can body 1 shown in fig. 1 and 2 is of a generally conical configuration with a generally oval cross-section. The device that prevents toppling over when jar body 1 is rotatory of this embodiment includes that chassis and a set of interval set up the bottom running roller 3 on the chassis, is connected with drive arrangement 2 on one of them bottom running roller 3, in this embodiment drive arrangement 2 includes motor and speed reducer. The device is characterized by also comprising a supporting structure 4 arranged at two sides of the bottom roller 3; preferably, the supporting arms 41 are symmetrically arranged on both sides of the bottom roller 3 along the center line of symmetry of the bottom roller 3.

The supporting structure 4 comprises a supporting arm 41, the lower end of the supporting arm 41 is pivoted on the base frame, the upper end of the supporting arm 41 is hinged with a universal roller assembly 42, the supporting arm 41 is also hinged with a telescopic device 5, one end of the telescopic device 5 is hinged on the supporting arm 41, and the other end of the telescopic device is hinged on the base frame. Preferably, the telescopic device 5 is a cylinder. The cylinder extends to drive the support arm 41 to move upwards, and the cylinder shortens to drive the support arm 41 to move downwards.

In this embodiment, as shown in fig. 3, the universal roller assembly 42 includes a universal roller 421, a first rotating frame 422 and a second rotating frame 423, the left and right ends of the universal roller 421 are pivotally connected to the first rotating frame 422, the upper and lower ends of the first rotating frame 422 are pivotally connected to the second rotating frame 423, and the left and right ends of the first rotating frame 422 are pivotally connected to the upper end of the supporting arm 41. Preferably, the first rotating frame 422 and the second rotating frame 423 are both rectangular structures. Preferably, the universal roller assembly 42 includes two universal rollers 421 disposed in parallel. Through the horizontal swing of the first rotating frame 422 and the vertical swing of the second rotating frame 423, the universal roller 421 can swing along with the change of the inclination angle of the tank surface and can be always attached to the surface of the tank body 1.

When the tank body machining device is used, as shown in fig. 1, a tank body 1 to be machined is placed on the bottom roller 3, the motor and the speed reducer drive the left bottom roller 3 to rotate, and the tank body 1 rotates along with the start of rotation. And starting the air cylinder, extending the air cylinder to enable the supporting arm 41 to swing upwards, and stopping extending the air cylinder after the universal roller assembly 42 is just attached to the surface of the tank body 1. Along with the rotation of the tank body 1, the air cylinder also extends or shortens, so that the universal roller wheel assembly 42 is always attached to the surface of the tank body 1 to support the tank body 1 and keep the shape of the tank body 1. In the process of turning the tank body 1 from the state shown in fig. 1 to the state shown in fig. 2, the right cylinder is gradually shortened to enable the right support structure 4 to swing downwards, the left cylinder is gradually lengthened to enable the left support structure 4 to swing upwards, and the roller wheel assembly is always supported on the surface of the tank body 1, so that the tank body 1 is kept undeformed. Preferably, the cylinder is electrically connected with a controller, and the controller is provided with a preset program and is used for controlling the cylinder to automatically stretch and retract, so that the universal roller 421 is always attached to the surface of the tank body 1 and has a moderate pressing force, the tank body is not damaged, and the effect of keeping the tank body 1 not deformed is achieved.
