Technical Field
[0001] The utility model relates to the technical field of polishing hanging brackets, in particular to a sandblasting and polishing hanging bracket for small castings. Background Technique
[0002] Because small castings are not convenient to hang and are numerous in quantity, when polishing, they are usually placed on the material rack in layers and then pushed into the polishing chamber for polishing. Due to the mutual shielding between the material rack and the castings, the castings often cannot be polished comprehensively. Even for some castings, the proportion of the polished surface is very small, and repeated polishing is required, resulting in low polishing efficiency and high cost.
[0003] Patent 2021224439942, a shot blasting machine with good fixing effect, discloses a polishing hanging bracket. However, the structure of this hanging bracket is simple, it is not applicable to small castings, and the hanging bracket cannot rotate automatically, nor can it polish the castings efficiently and with high quality. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sandblasting and polishing hanging bracket for small castings aiming at the deficiencies of the prior art. It adopts a hanging bracket welded by round steel with two layers of storage racks. When polishing, the hanging bracket can rotate automatically, thereby improving the polishing quality and efficiency.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a sandblasting and polishing hanging bracket for small castings, including a storage rack with a space gap of 50 - 200 mm formed by welding round steel in upper and lower layers, and a suspension rod passing through the centers of the two storage racks and welded to them. The two storage racks are respectively connected to the bottom end and the middle part of the suspension rod. There are 2 - 4 connecting rods arranged between the two storage racks, and at least three inclined stay rods are arranged between the upper storage rack and the upper end of the suspension rod; the top end of the suspension rod is rotationally connected to the suspension device through a bearing, and a pulley driven wheel is arranged below the suspension device on the suspension rod. The pulley driven wheel is connected to a pulley mechanism arranged in the polishing chamber.
[0006] Preferably, the storage rack includes a circular plate in the center and a circular ring on the outer periphery. There are at least 8 radial spokes circumferentially distributed between the circular plate and the circular ring. A transverse rib connecting the two spokes is arranged in the middle of any two adjacent spokes, and a short spoke in the radial direction is arranged between the transverse rib and the circular ring.
[0007] Preferably, except for the circular plate in the center of the storage rack, all other structures are made of round steel with a diameter of 14 - 22 mm.
[0008] Preferably, the space gap of the storage rack is 100 - 200 mm.
[0009] Preferably, a guardrail with a height less than 120 mm is provided at the edge of the stock rack.
[0010] Preferably, the suspension device includes a connecting part connected to the suspension rod and a hanging part with holes on the plate surface. The connecting part is a round tube and is internally provided with at least two thrust bearings.
[0011] Preferably, the dial wheel mechanism includes a dial wheel arranged at the top of the polishing chamber and driven by a motor to rotate. The dial wheel includes two upper and lower round plates, and a number of dial rods equal to the number of teeth of the driven dial wheel are circumferentially and evenly distributed along the edge of the two round plates.
[0012] The beneficial effects of the present utility model are as follows: A hanging rack for sandblasting and polishing small castings includes a stock rack welded by round steel with two upper and lower layers and a space gap of 50 - 200 mm, and a suspension rod passing through the centers of the two stock racks and welded to them. The two stock racks are respectively connected to the bottom end and the middle part of the suspension rod. There are 2 - 4 connecting rods arranged between the two stock racks, and at least three diagonal tension rods are arranged between the upper stock rack and the upper end of the suspension rod. The top end of the suspension rod is rotatably connected to the suspension device through a bearing. A driven dial wheel is arranged below the suspension device on the suspension rod, and the driven dial wheel is connected to a dial wheel mechanism arranged in the polishing chamber. The hanging rack of the present utility model is welded by round steel. The space gap of the stock rack is small, and small castings can be placed. In addition, the dial wheel mechanism arranged in the polishing chamber drives the driven dial wheel to rotate, thereby driving the hanging rack to rotate, so that more surfaces of the casting can be polished.

[0017] The following further describes the present utility model in detail with reference to the drawings and specific embodiments, and the scope of implementation of the present utility model is not limited thereto.
[0018] As Figures 1-2As shown in the figure, a sandblasting and polishing hanger for small castings in this embodiment includes a storage rack 1 composed of round steel welded into two upper and lower layers with a space gap of 50 - 200 mm, and a suspension rod 2 passing through the centers of the two storage racks 1 and welded to them. The two storage racks 1 are respectively connected to the bottom end and the middle part of the suspension rod 2. There are 2 - 4 connecting rods 3 arranged between the two storage racks 1. At least three diagonal tension rods 4 are arranged between the upper storage rack 1 and the upper end of the suspension rod 2. The top end of the suspension rod 2 is rotatably connected to a suspension device 5 through a bearing. A pulley driven wheel 6 is arranged below the suspension device 5 on the suspension rod 2. The pulley driven wheel 6 is connected to a pulley mechanism 7 arranged in the polishing chamber.
[0019] The hanger in this embodiment is mainly used for polishing small castings. After the hanger is placed with the castings, it is suspended in the polishing chamber. The pulley mechanism 7 is arranged at the top of the polishing chamber. The pulley mechanism 7 includes a pulley driven by a motor to rotate at the top of the polishing chamber. The pulley includes two upper and lower circular plates. Between the two circular plates, a number of push rods equal to the number of teeth of the pulley driven wheel 6 are circumferentially distributed along the edge of the circular plate. When the hanger is placed in the polishing chamber, the pulley driven wheel 6 is adjusted to mesh with the push rod of the pulley mechanism 7. In this way, the pulley mechanism 7 can drive the hanger to rotate through the pulley driven wheel 6, so that the castings stored on the hanger can be sandblasted and polished 360°.
[0020] In order to minimize the shielding of the castings by the hanger, except for the central circular plate 11 of the storage rack 1, all other structures are made of round steel with a diameter of 14 - 22 mm. Among them, at least eight radial spokes 13 are circumferentially distributed between the circular plate 11 and the outer ring 12. A transverse rib 14 connecting the two spokes 13 is arranged in the middle of any two adjacent spokes 13. A short spoke 15 is arranged between the transverse rib 14 and the outer ring 12 along the radial direction.
[0021] The suspension rod 2 and the suspension device 5 are connected through a thrust bearing. The thrust bearing is arranged inside the circular tubular connecting part 51 of the suspension device 5 to avoid the invasion of abrasive grains. The upper end of the suspension device 5 is a hanging part 52 with holes on the plate.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention. For the convenience of describing the technical solutions, the front, back, left, right, up, middle, down, etc. directions used are based on the drawings, rather than a limitation on the protection scope of the present invention.
