Abstract
Description
Technical Field
[0001] This utility model belongs to the field of resin sand blasting technology, and in particular relates to a rotating component of a resin sand blasting disc. Background Technology
[0002] The resin sand blasting disc is a core piece of equipment in the resin sand molding process of the foundry industry. It is mainly used to uniformly fill the sand box or mold with mixed resin sand and compact it to form a high-strength sand mold. Its core function is to use centrifugal force to propel the resin sand through a high-speed rotating blasting head (speed adjustable), achieving uniform coverage and density consistency across the sand box. To drive the blasting disc's rotation, a rotating component is required. However, the rotating component of the resin sand blasting disc still has the following drawbacks in practical use:
[0003] When the rotating component of the resin sand polishing disc is in operation, it is directly installed on the top cover and the motor is started. However, during operation, the installation of the rotating component requires multiple mounting bolts, which is not convenient.
[0004] Secondly, during the installation of the rotating component of the resin sand blasting disc, it is only installed on the feeding conveyor structure. As the work progresses, the blasting disc and the feeding structure will become loose, causing sand leakage and affecting the blasting stability of the resin sand blasting disc. Utility Model Content
[0005] The purpose of this utility model is to provide a rotating component for a resin sand blasting disc. By setting a top cover, a fixing ring, a rotating component, an inner disc, and a fixing platform, it solves the problems of inconvenient installation and operation of the rotating component of the resin sand blasting disc, and the loosening of the structure between the blasting disc and the feeding material during operation, which affects the stability of sand blasting.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a rotating assembly of a resin sand blasting disc, comprising a top cover, a fixing ring, a rotating assembly, an inner disc, and a fixing platform. The fixing ring is movably connected through the center of the top of the top cover. The inner disc is fixed to the inner wall of the fixing ring. The rotating assembly is movably connected in a ring array inside the fixing ring. The fixing platform is fixed in a ring array at the top of the top of the top cover outside the fixing ring. A speed reducer is fixed to the center of the top of the inner disc. An output shaft is fixed to the output end of the speed reducer. The bottom end of the output shaft is fixed to the main body of the blasting disc. During operation, the fixing ring is movably connected to the top cover, and the inner disc is fixed within the fixing ring and mounted on the top cover. The rotating assembly further restricts the top cover and the main body of the blasting disc during rotation. The speed reducer is connected to the inner disc and drives the main body of the blasting disc to rotate, enabling the blasting disc to perform sand blasting operations. The fixing platform movably connects the insert block within it.
[0008] Furthermore, the top cover has mounting ears fixed in a ring array around its periphery, and a feed cylinder is fixedly connected to the top of the top cover on one side of the fixing ring. The mounting ears on the top cover are movably connected to the supporting mounting structure.
[0009] Furthermore, the fixed ring has a ring-shaped array of through-holes with movable holes, and the rotating assembly includes a rotating rod that is inserted into the movable hole. The movable hole on the fixed ring is movably connected to the rod.
[0010] Furthermore, the rotating assembly also includes a handle and a locking plate. The handle is fixed to the top of the rotating rod, and the locking plate is fixed to the bottom of the rotating rod. The top of the locking plate is in contact with the top of the inner part of the top cover. When the handle rotates, it drives the locking plate to rotate through the rotating rod, further restricting the top cover and the sand-blasting disc body.
[0011] Furthermore, a drive motor is fixed to the top of the reducer, and the output end of the drive motor is fixed to the power input end of the reducer. The top of the sand-throwing disc body is open, and the top of the sand-throwing disc body is in contact with the bottom of the top cover. When the reducer is working, it is driven by the power generated by the drive motor.
[0012] Furthermore, each of the fixed platforms is movably connected with an insert block, and a fixed frame is movably connected to one end of the insert block near the fixed ring. The bottom of each fixed frame is fixed to the top of the fixed ring. When the fixed platform is in operation, the insert block is inserted into the fixed frame, thereby restricting the position of the top cover and the fixed ring together.
[0013] This utility model has the following beneficial effects:
[0014] This invention solves the problem of inconvenient installation and operation of the rotating component of the resin sand blasting disc by setting a top cover, a fixing ring, an inner plate, and a fixing platform. During the rotation of the blasting disc body, sand is thrown into the sand mold. When installing the fixing ring on the top cover, the drive motor above the blasting disc body passes through the top of the top cover until the fixing ring is movably connected to the top cover and rotates until the fixing frame is aligned with the fixing platform. Then, the insert block is inserted into the fixing platform and then extends into the fixing frame, so that the top cover and the fixing ring are connected together, making the installation and operation of the rotating component of the resin sand blasting disc more convenient.
[0015] This invention solves the problem of loosening between the sand-throwing disc and the feeding structure of a resin sand blasting disc during operation, affecting sand-throwing stability, by setting a top cover, a fixing ring, a rotating assembly, and an inner plate. After installing the fixing ring on the top cover, rotating the handle above the fixing ring causes the locking plate to rotate under the transmission of the rotating rod at the bottom of the handle until the handle drives the locking plate to contact the top of the inner part of the top cover, completing the operation. This effectively prevents loosening between the top cover and the sand-throwing disc body during operation. Furthermore, when disassembling the fixing ring and the inner plate, simply rotate the handle until it is fully positioned above the inner plate and the fixing ring, then release the top cover and the fixing ring. This ensures that the sand-throwing disc and the feeding structure of the resin sand blasting disc will not loosen during operation, guaranteeing sand-throwing stability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0026] Please see Figure 1-4 This utility model relates to a rotating assembly for a resin sand polishing disc, comprising a top cover 1, a fixing ring 2, a rotating assembly 3, an inner disc 4, and a fixing platform 5. The fixing ring 2 is movably connected through the center of the top of the top cover 1, sealing the top of the polishing disc body 404 and connecting the fixing ring 2, rotating assembly 3, inner disc 4, and fixing platform 5 thereon. The inner disc 4 is fixed to the inner wall of the fixing ring 2, connecting it within the fixing ring 2. The rotating assembly 3 is movably connected through a ring array inside the fixing ring 2, pressing the fixing ring 2 against the top cover 1. To prevent loosening between the top cover 1 and the sand-throwing disc body 404, a fixed platform 5 is fixed in a ring array at the top of the top cover 1 outside the fixed ring 2. The insert block 502 in the fixed platform 5 connects and restricts the top cover 1 and the fixed ring 2. A reducer 401 is fixed at the center of the top of the inner disc 4. An output shaft 403 is fixed at the output end of the reducer 401. The sand-throwing disc body 404 is fixed at the bottom end of the output shaft 403. The power generated by the reducer 401 is transmitted to the output shaft 403, which drives the sand-throwing disc body 404 to rotate. When the sand-throwing disc body 404 rotates, sand-throwing operation is performed.
[0027] Specifically, mounting ears 102 are fixed in a ring array around the periphery of the top cover 1. The top of the top cover 1 on one side of the fixing ring 2 is fixedly connected to the feed cylinder 101. The top cover 1 is provided for installation with the external support structure through the mounting ears 102. The top of the feed cylinder 101 is connected to the equipment for conveying sand, and the sand is conveyed into the top cover 1.
[0028] Furthermore, the fixed ring 2 has a ring array of through-holes 201, and the rotating component 3 includes a rotating rod 302, which is inserted into the movable hole 201. The movable hole 201 on the fixed ring 2 is movably connected to the rotating rod 302.
[0029] Furthermore, the rotating assembly 3 also includes a handle 301 and a locking plate 303. The handle 301 is fixed to the top of the rotating rod 302, and the locking plate 303 is fixed to the bottom of the rotating rod 302. The top of the locking plate 303 is in contact with the top of the inside of the top cover 1. The handle 301 is located directly above the locking plate 303. After rotating the handle 301, the locking plate 303 is rotated to contact the top of the inside of the top cover 1 under the transmission of the rotating rod 302, further preventing gaps from forming between the top cover 1 and the sand-blasting disc body 404.
[0030] The operation process of this embodiment is as follows: During operation, after the fixing ring 2 is installed on the top cover 1, the handle 301 above the fixing ring 2 is rotated. Under the transmission of the rotating rod 302 at the bottom of the handle 301, the locking plate 303 is rotated until the handle 301 drives the locking plate 303 to contact the top of the inner part of the top cover 1, thus completing the operation. This effectively prevents the top cover 1 and the sand-throwing disc body 404 from loosening due to vibration during operation. When disassembling the fixing ring 2 and the inner disc 4, the handle 301 is directly rotated until it is completely positioned above the inner disc 4 and the fixing ring 2, and then the top cover 1 and the fixing ring 2 are released. Specific Implementation Example 2
[0031] Please see Figure 1-6 Based on the first specific embodiment, a drive motor 402 is fixed at the top of the reducer 401. The output end of the drive motor 402 is fixed to the power input end of the reducer 401. The top of the sand-throwing disc body 404 is open. The top of the sand-throwing disc body 404 is in contact with the bottom of the top cover 1. When the drive motor 402 is working, it drives the reducer 401 to work. When the reducer 401 is working, it drives the sand-throwing disc body 404 to rotate.
[0032] Specifically, each fixed platform 5 is movably connected with an insert block 502. The end of the insert block 502 near the fixed ring 2 is movably connected with a fixed frame 501. The bottom of each fixed frame 501 is fixed to the top of the fixed ring 2. After the insert block 502 movably connected in the fixed platform 5 is inserted into the fixed frame 501 fixed to the top of the fixed ring 2, it restricts and determines the position of the top cover 1 and the fixed ring 2.
[0033] The operation process of this embodiment is as follows: During operation, the sand is conveyed into the top cover 1 through the feed cylinder 101 and falls into the sand-throwing disc body 404 inside the top cover 1. The drive motor 402 is started, and the drive motor 402 drives the reducer 401 to work, driving the output shaft 403 to rotate. During the rotation of the output shaft 403, the drive motor 402 drives the output shaft 403 to drive the sand-throwing disc body 404 to rotate. During the rotation of the sand-throwing disc body 404, the sand is thrown into the sand mold. When installing the fixing ring 2 on the top cover 1, the drive motor 402 above the sand-throwing disc body 404 passes through the top of the top cover 1 until the fixing ring 2 is movably connected to the top cover 1 and rotates until the fixing frame 501 is aligned with the fixing platform 5. Then, the insert block 502 is inserted into the fixing platform 5 and then extended into the fixing frame 501, so that the top cover 1 and the fixing ring 2 are connected together.
