[0034] The working principle of the grinding device for a high-pressure water pump housing provided by the utility model is as follows:

[0035] By starting the first servo motor 15, the output shaft of the first servo motor 15 can drive the two-way threaded rotating rod 4 to rotate, so that the two L-shaped threaded plates 5 on the two-way threaded rotating rod 4 can move toward each other. At this time, the two L-shaped threaded plates 5 will drive the two connecting rotating plates 9 to rotate upward, so that the two connecting rotating plates 9 can drive the two blocking plates 6 to slowly rotate downward, so that the two blocking plates 6 can fit and limit to the left and right sides of the grinding disc rotating rod 28 to play a role in blocking splashing debris, and then the protective plates 13 at the two support plates 11 are rotated upward, so that the protective plates 13 are blocked in front of the grinding disc rotating rod 28, and then the two L-shaped baffles 32 at the L-shaped bottom plate 25 can be blocked behind the grinding disc rotating rod 28, so as to perform splash-proof work on the surroundings of the grinding disc rotating rod 28, avoid debris splashing around and injuring people, improve the safety of the grinding device, and at the same time, the blocked debris will fall into the inside of the collection card box 10, so as to collect the grinding debris in a centralized manner, reduce the workload of the workers, and help improve the working efficiency of the grinding device;

[0036] By placing the water pump housing into the center of the grinding table 2, the two L-shaped threaded plates 5 move toward each other and drive the arc-shaped clamping plates 17 or the square clamping plates 18 at the two rotary blocks 16 to clamp water pump housings of different sizes respectively, so that the grinding device can flexibly adapt to different water pump housings. Then the No. 1 rubber strip 21 at the arc-shaped clamping plate 17 and the No. 2 rubber strip 22 at the square clamping plate 18 can increase the friction with the water pump housing, so that water pump housings of different sizes can be firmly positioned, ensuring that the grinding work is carried out stably and reliably. Then, the grinding disc rotating rod 28 is snap-fitted to the bottom of the shaft seat 26, and the positioning plate 29 is inserted into the interior of the shaft seat 26 and the grinding disc rotating rod 28 to fix the grinding disc rotating rod 28. Subsequently, the first bolt 30 and the second bolt 31 are used to reinforce the installation of the grinding disc rotating rod 28, so as to facilitate the rapid snap-fit ​​assembly of the grinding disc rotating rod 28 and improve the installation efficiency of the grinding disc rotating rod 28. In this way, it is convenient for the output shaft of the second servo motor 27 to drive the grinding disc rotating rod 28 at the shaft seat 26 to rotate and grind the water pump housing, which is easy to use.
