It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a school shape frock, including two gyro wheels 1 that set up side by side, drive lead screw subassembly 2 and equipment principal 3, the 3 lower extremes of equipment principal is provided with recess 31, two 2 one ends of drive lead screw subassembly are installed on the lateral wall of recess 31, two there is the clearance between the gyro wheel 1, gyro wheel 1 tip passes through bearing assembly 11 and connecting piece 12 one end swing joint, the connecting piece 12 other end with the output of drive lead screw subassembly 2 is connected, two pressure sensor 13 is installed respectively to 1 lateral part of gyro wheel. Specifically, in the embodiment, the correction part 100 is provided with a rib 101 to be corrected, the two rollers 1 are used for clamping the rib 101, and the screw rod assembly 2 is driven to start working. Firstly, whether the pressure between the roller 13 and the rib 101 reaches a preset value or not is detected through the pressure sensor 13 arranged on the side of the roller 13, if the pressure does not reach the preset value, the two driving screw rod assemblies 2 start to do work synchronously, the two rollers are driven to move oppositely through the connecting piece 12, and the rib 101 is further tightened. If the pressure sensor 13 detects that the pressure reaches a preset value, the screw rod assembly 2 is driven to stop acting and is locked, and the pressure between the roller 1 and the ribs 101 is kept constant. Further, the external world gives 3 thrust of equipment principal, the drive equipment principal 3 begins the displacement along the direction of rib 101, because gyro wheel 1 is connected with connecting piece 12 through bearing assembly 11, when equipment principal 3 begins the displacement, two gyro wheels 1 can be rotatory along rib 101, and then accomplish the school shape to rib 101 under the state that keeps certain pressure, very big improvement the efficiency and the qualification rate of school shape, need not the artifical butt joint of high technique and school shape, reduce the human cost of enterprise.

As shown in fig. 1-2, the connecting member 12 is an L-shaped member composed of a short plate 121 and a long plate 122, the driving screw assembly 2 includes a driving motor 21 and a screw rod 22, the driving motor 21 is installed on the side wall of the groove 31, one end of the screw rod 22 is connected to the output end of the driving motor 21, and the other end of the screw rod 22 is movably connected to the short plate 121. Specifically, in this embodiment, when the driving motor 21 starts to operate, the screw rod 22 is driven to rotate, and the short plate 121 of the connecting member 12 is in threaded connection with the screw rod 22, so that the connecting member 12 can convert the rotation motion of the screw rod 22 into a linear motion, and further drive the roller 1 to approach or leave the rib 101.

As shown in fig. 1-2, a linear guide 311 is disposed on the top wall of the groove 31, and the linear guide 311 is slidably connected to the long plate 122 in the length direction. Specifically, set up linear guide 311, when driving motor 21 drive connecting piece 12 displacement, linear guide 311 injects the displacement direction of connecting piece 12, produces when avoiding connecting piece 12 left and right sides displacement and rocks, leads to gyro wheel 1 to rock in step, reduces the school shape quality.

As shown in fig. 1-2, a stopper 312 is disposed on one side of the linear guide 311 near the gap between the two rollers 1, and a travel switch 313 is further mounted on the top wall of the groove 31. Specifically, the stopper 312 is provided to limit the linear guide 311 from exceeding the limit. Meanwhile, a travel switch 313 is provided to prevent the apparatus body 3 from colliding with other components driven by an external force.
