Detailed Description
The operation of the positioning tool for washing and cutting the double-screw vacuum pump shell of the utility model is further explained by combining with the figures 1 to 4.
The utility model provides a twin-screw vacuum pump casing is washed and is cut and use location frock which characterized by: comprises a bottom plate 1, a pressure plate 2 and a horizontal positioning rod 3. The central point of clamp plate 2 puts and has seted up the through-hole, and the cooperation has screw rod 22 in the through-hole, the lower extreme cartridge of screw rod 22 is and welded fastening is on bottom plate 1, and the last pot head of screw rod 22 is equipped with lock nut 21 that can push down clamp plate 2, and lock nut 21 is located the top of clamp plate 2 promptly, and lock nut 21 rotates to move down the back and can support and press clamp plate 2. The bottom plate 1 is provided with a positioning block 11, the horizontal positioning rods 3 are provided with a plurality of horizontal positioning rods, the horizontal positioning rods are matched on the positioning block 11 in a horizontal threaded mode, and the end portions of the horizontal positioning rods 3 are abutted to the inner wall of the shell 4 placed on the bottom plate 1 respectively.
Specifically, the horizontal positioning rod 3 is a positioning bolt, and the head of the rod body of the positioning bolt is arranged in an arc surface. Because the inner wall of casing 4 is the arcwall face, consequently sets up positioning bolt's body of rod terminal surface into the cambered surface can laminate each other with casing 4 inner wall as far as to reach more stable location effect. Furthermore, a pressing sleeve is sleeved on the end face of the rod body of the positioning bolt, and the cambered surface at the end part of the rod body is the end part of the cambered surface of the pressing sleeve.
The two positioning blocks 11 are distributed on the left side and the right side of the screw 22, the six horizontal positioning rods 3 are distributed on the two positioning blocks 11 respectively, and the three horizontal positioning rods 3 on each positioning block 11 are abutted to the side face and the front face and the rear face of the shell 4 respectively. As shown in fig. 3, the end surfaces of the three horizontal positioning rods 3 on the left positioning block 11 respectively press against the front inner side surface, the rear inner side surface, and the left inner side surface of the housing 4, and the end surfaces of the three horizontal positioning rods 3 on the right positioning block 11 respectively press against the front inner side surface, the rear inner side surface, and the right inner side surface of the housing 4.
The positioning block 11 is fixed on the bottom plate 1 through bolts or welding.
