Pressure ware

[0016] like Figure 1 to Figure 6 As shown, a pressure device includes a bottom support 1, a vertical support 2 and a support base 9 on both sides of the bottom support 1, an upper support 3 at the top of the longitudinal support 2, a cylindrical spacer 4 above the upper support 3, and a screw rod 6 vertical Through the block 4, its upper and lower ends are respectively connected with the handwheel 5 and the pressure head 7, and the cylindrical platform 8 is directly below the pressure head 7, and the platform 8 is fixed on the bottom support 1. The bottom support 1, the longitudinal support 2 and the upper support 3 are made of channel steel, and the bottom support 1 is channel steel with two notches facing each other and placed in parallel at intervals. There are two longitudinal supports 2 in the interval, and the upper support 3 is also composed of two It is composed of channel steel with opposite notches and spaced in parallel. The support base 9 is four triangular steel members, which are welded to the vertical support 2 in pairs. The vertical support 2 is connected with the base support 1 and the upper support 3 through bolts 10 and nuts 11 respectively.

[0017] Pad block 4 is a circular iron block, has two screw holes on it, and links to each other with upper support 3 by countersunk bolt 12 and countersunk nut 13 . Both the cushion block 4 and the lower surface of the platform 8 have a clamping part 14, and a pair of parallel planes 15 are arranged on the clamping part 14. Through a pair of parallel planes 15 on the clamping part 14 , the lower end of the spacer 4 is clamped in the upper support 3 and is located in the middle position, and the lower end of the platform 8 is clamped in the bottom support 1 . There is a threaded hole in the center of the cushion block 4, and the screw rod 6 penetrates vertically, and the pressure head 7 and the hand wheel 5 are also connected to the screw rod 6 through threads.

[0018] When in use, by rotating the handwheel 5, the screw rod 6 is driven, and the screw rod 6 moves downward, and the pressure head 7 gradually touches the surface of the workpiece, so that the leveling work is completed under the joint action of the platform 8 and the pressure head 7.
