The box body 19 is disposed within the linkage belt 26, and the four auxiliary driving sliders 41 are symmetrically slidably engaged in pairs on the inner wall of the sand and gravel collection mechanism 2. The transverse sliding track 42 and the longitudinal sliding track 40 are respectively disposed on two pairs of auxiliary driving sliders 41, and the driving main slider 39 is slidably engaged on the transverse sliding track 42 and the longitudinal sliding track 40. The main driving wheel 37 is vertically disposed on the driving main slider 39, the driving universal joint 44 is disposed at the movable end of the main driving wheel 37, and the grinding head 43 is disposed at the movable end of the driving universal joint 44.

[0037] Working principle: During use, first, when the casting group 25 is sent onto the flipping mechanism 9, if the openings of the multiple hemispherical castings 24 are upward, the flipping mechanism 9 does not operate. If the openings of the hemispherical castings 24 are downward, then control the telescopic support plates 11 on the flipping bar one 7 and the two flipping bars two 8 to extend and retract back and forth, so that the arc surfaces of the hemispherical castings 24 fall into the magnetic groove seats 6, and at the same time, the magnetic groove seats 6 operate to align and perform magnetic adsorption. Then control the motor 10 to flip the hemispherical castings 24 so that the openings of the hemispherical castings 24 are downward.

[0038] Then it is sent onto the rubber groove seat 29 in the middle slot 16, and then the driving slider 14 is controlled to slide down along the main slideway 15, so that the magnetic pressing plate 13 adsorbs and fixes the hemispherical casting 24. The auxiliary driving slider 41 in the box body 19 is controlled to move the driving main slider 39 to a specified position. Then the main driving wheel 37 is controlled to extend, and at the same time, the driving wheels 36 are respectively controlled to rotate to draw out the upper sliding cross plate 34 originally used for clamping to prevent the deformation of the rubber groove seat 29. At this time, the extensional deformation performance of this part of the strip groove 33 is improved. At the same time, the driving wheel 36 in contact with the slide bar 35 is controlled to work to move the slide bar 35, so as to make room for the inner space of the strip groove 33 under the specific hemispherical casting 24 on the rubber groove seat 29. At the same time, the electric telescopic rod 3 is controlled to contract. At this time, the four support rods 22 are expanded against the inner walls of the two rubber groove seats 29 under the action of the electric telescopic rod 3. Thereby, the opening area of this part of the strip groove 33 is enlarged. Then the grinding head 43 passes through the enlarged part of the strip groove 33 and contacts the inner wall of the hemispherical casting 24. At this time, a relatively closed space is formed between the hemispherical casting 24 and the strip groove 33, which is convenient for the grinding head 43 to clean the sand falling on the inner wall of the hemispherical casting 24. At the same time, the enlarged part of the strip groove 33 is also more convenient for the caked sand and gravel to fall into the box body 19.

[0039] Moreover, the expansion size of this part of the strip groove 33 can be controlled by controlling the retraction amplitude of the electric telescopic rod 3. Then when the grinding head 43 is extruded or retracted from the strip groove 33, the grinding bumps 23 on the inner wall of the rubber groove seat 29 clean the surface of the grinding head 43. Compared with the traditional method that the personnel need to clean the grinding head separately afterwards, or the separate cleaning of the grinding head is not carried out in a closed space, the present invention can realize the functions of sand falling work and grinding head maintenance simultaneously in a relatively closed space.

[0040] To sum up, for the sand falling treatment device for thin-walled hemispherical castings, through the mutual cooperation of the bottom plate 1, the sand collection mechanism 2, the electric telescopic rod 3, the conveyor belt mechanism 18, the workbench 17, the flipping mechanism 9, the main slideway 15, the magnetic pressing plate 13 and the driving slider 14. The present invention has the advantage of using the relatively closed space formed between the hemispherical casting and the workbench, so that when the sand falling treatment is carried out, no sand dust will be raised. It is convenient for the personnel to work. At the same time, it also solves the problem of the personnel cleaning the sand and debris on the grinding assembly afterwards.
