When the second sliding rods 9 slide to the third sliding holes When the second slide bar 9 slides to the bottom of the arc-shaped side of the third slide hole 10, the first clamping shaft 707 of the clamping assembly 7 moves to clamp with the second fixing hole 19 of the rotating shell 4, and the first processing surface 12 of the water pump housing 3 is processed; when the second slide bar 9 slides to the arc-shaped top of the third slide hole 10, the clamping assembly 7 is clamped with the two second slide bars 9 to limit and fix the position of the rotating shell 4, and the processed top surface 11 at the top of the water pump housing 3 is processed; when the second slide bar 9 slides to the bottom of the other side of the arc of the third slide hole 10, the second processing surface 13 of the water pump housing 3 is processed, and the second clamping shaft 711 of the clamping assembly 7 moves to clamp with the first fixing hole 18 of the rotating shell 4, so as to achieve multi-station processing of the water pump housing 3.

[0045] Among them, the working principle of the positioning component 1 for positioning the first side and the second side of the bottom of the water pump housing 3 is as follows: the output shaft of the first motor 109 drives the cam 108 to rotate, and during the process in which one end of the resistance rod 103 resists against the cam 108, the resistance rod 103 slides in the horizontal direction on the first fixed plate 104, and the resistance rod 103 drives the fixed block 106 to move in the horizontal direction.

[0046] Among them, the working principle of the four-position pressing assembly 2 pressing the bottom of the water pump housing 3 is as follows: The output shaft of the second motor 208 drives the fifth helical gear 210 to rotate. The fifth helical gear 210 drives the third helical gear 207 to rotate through meshing transmission with the third helical gear 207. The third helical gear 207 drives the second helical gear 205 to rotate through the third rotating shaft 206. The second helical gear 205 drives the first helical gear 204 to rotate through meshing transmission with the first helical gear 204. The first helical gear 204 drives the second gear 215 to rotate.
