The lifting driving device 7 is a telescopic linear motion device. An upper end of the lifting driving device 7 is hinged and fixed to a portion of the moving plate 5 deviated from the driving wheel 51, while a lower end thereof is hinged and fixed to the soleplate. The lifting driving device 7 is an air cylinder.
The motor holder 2 is fixed on a slider 80, the slider 80 is slidingly fixed on a slide rail 81 arranged in a front-rear direction, and the slider 80 is linked with a linear driving device 83. The linear driving device 83 is an air cylinder. The motor holder 2 includes a holding plate 20. The supports 3 are arranged at left and right ends of the holding plate 20, respectively.
The supports 3 include a first support 31 and a second support 32. The first support 31 is located on the left side of the second support 32. The end face runout detection sensor 4 is located above the first support. The second support 32 is located on the right of the end face runout detection sensor 4. A second limiting portion 33 is arranged on a side of the second support 32 away from the end face runout detection sensor. Locating grooves 37, which are open upward, are formed on both the first support 31 and the second support 32. The locating grooves are V-shaped or U-shaped grooves. The locating groove on the second support 32 runs through the second support 32 from the left and right sides. A fixation hole 30, which runs through the second limiting portion 33 from left and right sides, is formed on the second limiting portion 33.
