Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection, in particular to a pressure monitoring and adjusting device for a pressing roller. Background Art

[0002] In flaw detection production, the steel bar on the roller is fixed by pressing down the roller to reduce the vibration of the steel bar on the roller, so as to reduce the false alarm caused by vibration during the flaw detection process. The greater the pressure of the pressing roller, the better the stability of the steel bar fixed on the roller, but it will cause wear of the roller and the pressing rod, and after a long time, the wear of the roller will cause scratches on the surface of the steel bar and cause irreversible damage to the test sample bar. On the contrary, the smaller the pressure, the worse the stability of the steel bar on the roller, which will lead to inaccurate length measurement and reduced test stability, seriously affecting the performance of the equipment. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the background technology, the utility model seeks protection for a pressure monitoring and adjustment device for a pressing roller.

[0005] It also includes a controller, which is connected to the pressure sensor and the pressure roller height control device. According to the pressure sensor data, the pressure roller height control device is controlled to adjust the pressure roller height to achieve pressure regulation.

[0006] Furthermore, an equipment rack is arranged above the roller, and a grating sensor is arranged at the bottom of the equipment rack extending to both sides of the roller, and the grating sensor is connected to a controller to transmit sensing information.

[0007] Furthermore, an equipment rack is arranged above the roller table, the cylinder is arranged on the equipment rack and connected via an air valve, and the air valve is connected to a controller.

[0008] Furthermore, the cylinder driving end is connected to the bracket, and the pressure sensor is arranged at the driving end. The bracket is connected to a pressing roller through a pressing roller height control device, and the cylinder drives the bracket to drive the pressing roller to achieve downward pressure.

[0009] Furthermore, the press-down roller height control device includes a position sensor and a height control motor, and adjusts the position of the press-down roller by sensing position information.

[0010] Beneficial effect: Compared with the prior art, the utility model has the following advantages: the pressure of the pressing roller can be monitored in real time, and the pressure of the pressing roller can be controlled by controlling the pressing process of the pressing roller, so that the pressing pressure can be within a controllable range according to the experience gained in production, which can reduce the wear of the roller caused by excessive pressure, and can also reduce the test stability caused by too low pressure, and eliminate inaccurate length measurement caused by too low pressure.
