Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the detection platform that comma scraping roll has been installed, and this test platform comprises operator's console 1, right support 2, clamp cap 3, pedestal 4, line slideway 5, dolly 6, sensor stand 7, gear 8, drive motor 9, sensor 10, tooth bar 11, mark piece 12, swivel mount 13, left socle 14.

Operator's console 1 is the basis of detection platform, and for relevant device provides support and stationary installation, the length and width height is respectively 2300mm, 600mm, 800mm.Operator's console 1 is a steel structure platform, is welded to each other by the 80mm channel-section steel to constitute the platform base support, and the 1mm sheet steel is installed in platform base support side, and the 15mm steel plate is installed above, and steel plate is welded on the steel structure platform.Left socle 14, right support 2 are 24mm and 56mm steel plate, and all are fixed on the operator's console, as the bracing frame of comma scraping roll.All be drilled with the semicircle orifice that diameter is 50mm on left socle 14 and the right support 2, during detection, the comma scraping roll right-hand member is placed in this hole, and should hold fixing by clamp cap 3.Left socle 14 also is fixed on the operator's console 1, and the left end of comma scraping roll freely is placed on left socle 14.Swivel mount 13 is fixed on the operator's console 1, and is positioned at the outside of left socle, and swivel mount 13 can rotate around the axis of self, and cantilever lever is fixed on the swivel mount 13, and is arranged vertically with swivel mount 13, can rotate together along with swivel mount 13.Mark piece 12 is installed on the cantilever lever, and mark piece 12 can slide on cantilever lever, and the bottom of mark piece 12 is processed with a workplace, and this workplace can fit with the comma scraping roll knife-edge plane.During detection, demarcate the position of comma scraping roll 15 knife-edge plane with the workplace of mark piece bottom.The rotation comma scraping roll is to the detection position, rotation swivel mount 13 makes cantilever lever axis and comma scraping roll parallel axes, move mark piece 12 to edge of a knife position, adjusting comma scraping roll fits its knife-edge plane and the workplace of mark piece 12, the chucking comma scraping roll, shift out mark piece 12, swivel mount rotates back to original position, begins to detect.Pedestal 4 is by being bolted on the operator's console 1, and as the support of line slideway 5 and tooth bar 11, line slideway 5 and tooth bar 11 are by parallel being fixed on the pedestal 4 of bolt.The comma scraping roll axis parallels with line slideway 5 and tooth bar 11.
