Description

Technical Field

[0001] This utility model relates to the technical field of sand box turning equipment, and in particular to an adjustable sand box turning equipment. Background Technology

[0002] In casting production, during the forming of sand boxes, in order to ensure the uniformity of water glass inside the sand box and facilitate processing, as well as to facilitate operations such as pouring, cooling, sand removal, and material discharge, a sand box turning mechanism is generally set up on the mobile production line. The existing sand box structure includes a box body and two lifting lugs, which are fixed at both ends of the sand box. When it is necessary to turn the sand box, an electric hoist is used to hook the lifting lugs to lift the sand box, or a clamping mechanism is used to clamp and lift the sand box before turning it.

[0003] When using sand box turning equipment, the stability is poor when lifted by the lifting lugs, making it inconvenient to control precisely. When lifted and turned by the clamping mechanism, the position of the sand box cannot be adjusted. Moreover, the sand box usually follows different operations before and after turning, such as taking out castings or pouring sand, which is inconvenient to do in the same position. Therefore, we propose an adjustable sand box turning equipment. Utility Model Content

[0022] Reference Figures 1-7This embodiment is an adjustable sand box tilting device, including a lifting frame 1. A support sleeve 2 is liftably connected to the side of the lifting frame 1. An adjusting inner tube 3 is slidably sleeved on the support sleeve 2. The adjusting inner tube 3 has a slot inside that mates with the support sleeve 2. A servo motor 4 is fixed to the end of the adjusting inner tube 3 away from the lifting frame 1. Moving screws 12 are symmetrically fixed on the upper and lower sides of the support sleeve 2 near the servo motor 4. The moving screws 12 are slidably sleeved inside the adjusting inner tube 3. Nuts are threaded onto the outer movable screws 12. Adjustment grooves that mate with the movable screws 12 are provided at both the upper and lower ends of the inner tube 3. Each movable screw 12 is T-shaped. A support frame 5 is fixed to the output end of the servo motor 4. A double-rod cylinder 6 is installed at the bottom of the support frame 5. Clamping plates 7 are fixed to the output ends on both sides of the double-rod cylinder 6. Removable pads 8 are fixed to the opposite sides of the clamping plates 7 away from the double-rod cylinder 6. A rotating component is provided at the bottom of the lifting frame 1 to drive the lifting frame 1 to rotate.

[0023] In this embodiment, a servo motor 13 is installed on the top of the lifting frame 1. Lifting screws 24 are symmetrically connected inside the lifting frame 1 through bearings. Pulleys 21 are fixed on the top of the two lifting screws 24. The two pulleys 21 are connected by a transmission belt 22. One of the lifting screws 24 passes through the top surface of the lifting frame 1 and is fixed on the output end of the servo motor 13. Support sleeves 2 are threaded on both lifting screws 24.

[0024] In this embodiment, each pad 8 is fixed with a fixing sleeve 9 on the side near the clamping plate 7. Each fixing sleeve 9 has a fixing block 10 inserted inside it. Each fixing sleeve 9 has a horizontally placed convex groove that mates with the fixing block 10. The side of the fixing sleeve 9 away from the limiting plate 11 is open. The side of the fixing block 10 away from the pad 8 is fixed to the side of the clamping plate 7. The limiting plate 11 is slidably inserted inside the clamping plate 7 on the side of the fixing sleeve 9 to limit and fix the fixing sleeve 9. The side end of the limiting plate 11 is fixed to the clamping plate 7 by bolts. Each limiting plate 11 is T-shaped and placed horizontally. Each clamping plate 7 has a through groove that mates with the limiting plate 11. The end of the clamping plate 7 and the inside of the limiting plate 11 have threaded holes that mate with each other.

[0025] In this embodiment, the rotating assembly includes a limiting sleeve 15, a fixed base plate 16, and a rotating base 17. A connecting plate 14 is fixed to the bottom of the lifting frame 1, and the rotating base 17 is fixed to the bottom of the connecting plate 14. The limiting sleeve 15 is rotatably sleeved on the rotating base 17. The fixed base plate 16 is fixed to the bottom surface of the limiting sleeve 15 by bolts. A gear 18 is fixed to the upper outer surface of the rotating base 17. A gear 29 is meshed with the side of the gear 18. The bottom of the gear 29 is rotatably connected to the top surface of the limiting sleeve 15 by a bearing. A servo motor 30 is installed on the top surface of the fixed base plate 16 on the side of the limiting sleeve 15. Another pulley 21 is fixed to the output end of the servo motor 320 and the lower part of the gear 29. The two other pulleys 21 are connected by another transmission belt 22.

[0026] In this embodiment, the fixed base plate 16 has several fixing holes for fixing the fixed base plate 16 and ensuring the stability of the flipping device during operation. The limiting sleeve 15 has an inverted T-shaped rotating groove that cooperates with the rotating base 17 to facilitate the stable rotation of the lifting frame 1. The bottom of the rotating base 17 is equidistantly fitted with several ball bearings 23. The bottom surface of each ball bearing 23 is rolled on the top surface of the fixed base plate 16. The rolling connection makes the lifting frame 1 more labor-saving when rotating.

[0027] Working principle: When the sand box needs to be flipped, adjust the distance between the clamping plate 7 and the lifting frame 1 according to the size of the sand box or the position between the sand box placement point and the unloading point. During adjustment, tighten the nut on the moving screw 12 to release the clamping fixation of the nut on the adjusting inner tube 3. Pull the adjusting inner tube 3 to adjust the distance between the clamping plate 7 and the lifting frame 1. After adjustment, tighten the nut to tighten the adjusting inner tube 3 again. Then, fix the fixing base plate 16 to the bottom surface using the fixing parts. Select the corresponding pad 8 according to the size of the sand box. The fixing sleeve 9 of the pad 8 is fitted onto the fixing block 10. Push the limiting plate 11 to the side of the sealing end of the fixing sleeve 9 to limit the fixing sleeve 9. Then, tighten the bolts into the inside of the clamping plate 7 and the limiting plate 11 to fix the limiting plate 11 to the inside of the clamping plate 7. When flipping, place the sand box between the two pads 8. The servo motor 13 runs, driving the lifting frame connected to it. The lowering screw 24 rotates, and the lifting screw 24 drives another lifting screw 24 to rotate through the pulley 21 and the transmission belt 22. Under the action of the thread, the support sleeve 2 moves down, thereby moving the pad 8 down to both sides of the sand box. Then the double-rod cylinder 6 runs, driving the two clamping plates 7 to move relative to each other and clamp the sand box. Then the servo motor 213 runs, driving the sand box to move up. After moving up, the servo motor 320 runs, driving the other pulley 21 to rotate. The other pulley 21 drives the gear 22 to rotate through the transmission belt 22. The gear 21 drives the meshing gear 18 to rotate. The rotation of gear 18 drives the rotating base 17 to rotate. When the rotating base 17 rotates, it drives the ball bearing 23 to roll on the bottom surface of the fixed base plate 16. After rotating the sand box to the required position, the servo motor 4 runs, driving the sand box to flip. After the flipping operation is completed, the double-rod cylinder 6 runs again to put the sand box down, so that the next sand box can be flipped.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
