Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a polishing machine for investment casting. Background Technology

[0002] A polishing machine for investment casting is a device specifically designed for polishing the surface of castings during the investment casting process. The polishing machine mainly uses a high-speed rotating polishing wheel or polishing belt, along with a polishing agent, to rub the surface of the casting, thereby removing burrs, oxides, and uneven parts, making the surface of the casting smooth.

[0003] Existing polishing machines, whether handheld or stationary, require operators to use the polisher to polish the casting from multiple angles, or to continuously adjust the casting's position to bring it closer to the polisher. These methods necessitate operators adjusting their posture to match the machine or casting, resulting in low safety. Furthermore, the polishing debris can easily scatter into the air, affecting the operator's health. Therefore, those skilled in the art have provided a polishing machine for investment casting to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a casting polishing machine for investment casting, which solves the problems of traditional polishing equipment or methods that require operators to adjust their own state to match the equipment or casting body, resulting in low safety, and the fact that the debris generated during polishing is easily splashed into the air, affecting the operator's health.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polishing machine for investment casting, comprising a worktable, a toothed ring disposed in the middle of the worktable, a retaining ring installed on the outer wall of the toothed ring, a hollow bracket installed inside the toothed ring, a gear meshing on the lower side of the toothed ring, a rotating shaft installed on one side of the gear, a transparent protective cover disposed on the upper side of the worktable, a hydraulic rod connected to one side of the transparent protective cover, a through groove opened on the side of the transparent protective cover away from the hydraulic rod, a transparent protective plate slidably inserted into the through groove, a motor mounted on the transparent protective plate, a polishing disc driven by the output end of the motor facing the inside of the transparent protective cover, a limit bolt rotatably sleeved at the bottom of the transparent protective cover, a spring sleeved around the periphery of the limit bolt, and a pressure plate installed at the lower end of the limit bolt.

[0006] Preferably, the toothed ring is rotatably engaged with the center of the worktable via a retaining ring, a fixed sleeve is installed at the front end of the bottom side of the worktable, and the rotating shaft is rotatably engaged with the fixed sleeve. When the rotating shaft is rotated, the gear can drive the toothed ring to rotate inside the worktable, thereby driving the casting placed on the hollow support to rotate.

[0007] Preferably, the bottom end of the hydraulic rod is fixedly installed to the worktable, and the bottom side of the transparent protective plate is fixedly installed to the worktable. Under the protection of the transparent protective cover and the transparent protective plate, the debris generated during grinding can be blocked and fall to the bottom of the worktable through the hollow bracket, thus avoiding the problem of debris flying during grinding.

[0008] Preferably, the lower end of the spring is in contact with the pressure plate, and the upper end of the spring is in contact with the top side wall of the transparent protective cover. The limiting bolt that is rotatably engaged at the bottom of the transparent protective cover drives the pressure plate to press against the top of the casting under the pressure of the spring, thereby pressing and stabilizing the casting on the hollow support.

[0009] Compared with the prior art, this utility model provides a polishing machine for investment casting, which has the following advantages:

[0010] This casting polishing machine, through its design, consists of a worktable, a toothed ring, gears, a polishing disc, and a transparent protective cover. When polishing a casting is required, a hydraulic rod lifts the transparent protective cover, placing the casting on a hollowed-out bracket inside the toothed ring. The hydraulic rod then retracts, causing the transparent protective cover to descend. As the cover descends, a limiting bolt at the bottom of the cover rotates, causing a pressure plate to press against the top of the casting, thus securing the casting on the hollowed-out bracket. The motor then drives the polishing disc to rotate. Combined with the toothed ring, which rotates via gears and a rotating shaft, the casting can be polished from multiple angles. This eliminates the need for prolonged contact between the operator and the casting or equipment, improving safety during polishing. Furthermore, the transparent protective cover and protective plate prevent debris from flying and affecting personal health. Attached Figure Description

A fixing sleeve 101 is installed at the front end of the bottom side of the workbench 1. The rotating shaft 4 is rotatably engaged with the fixing sleeve 101. When the rotating shaft 4 is rotated, the gear 3 can drive the toothed ring 2 to rotate within the workbench 1, thereby driving the casting placed on the hollow bracket 201 to rotate. The bottom end of the hydraulic rod 5 is fixedly installed with the workbench 1, and the bottom side of the transparent protective plate 10 is fixedly installed with the workbench 1. The transparent protective cover 6 and Under the protection of the transparent protective plate 10, the debris generated during grinding can be blocked and fall below the workbench 1 through the hollow bracket 201, avoiding the problem of debris flying during grinding. The lower end of the spring 9 is in contact with the pressure plate 8, and the upper end of the spring 9 is in contact with the top side wall of the transparent protective cover 6. The limiting bolt 7, which is rotated and locked at the bottom of the transparent protective cover 6, drives the pressure plate 8 to press against the top of the casting under the pressure of the spring 9, thereby pressing and stabilizing the casting on the hollow bracket 201.

[0020] The casting polishing machine in this utility model consists of a worktable 1, a toothed ring 2, a gear 3, a polishing disc 12, and a transparent protective cover 6.

[0021] A hollow bracket 201 is installed inside the toothed ring 2, and a retaining ring 202 is installed on the periphery of the toothed ring 2. The toothed ring 2 is rotatably engaged with the center of the worktable 1 through the retaining ring 202. There is a fixed sleeve 101 at the bottom front end of the worktable 1. A rotating shaft 4 is rotatably engaged inside the fixed sleeve 101. One end of the rotating shaft 4 is fixedly installed with a gear 3. The gear 3 meshes with the tooth groove on the bottom side of the toothed ring 2. When the rotating shaft 4 is rotated, the gear 3 can drive the toothed ring 2 to rotate inside the worktable 1, thereby driving the casting placed on the hollow bracket 201 to rotate.

A motor 11 is installed on the transparent protective plate 10. The end of the motor 11 facing the inside of the transparent protective cover 6 drives a polishing disc 12. The casting on the hollow support 201 can be polished and ground through the polishing disc 12.

[0023] When polishing is required, the transparent protective cover 6 is lifted by the hydraulic rod 5, and the casting is placed on the hollow bracket 201 inside the toothed ring 2. Then, the hydraulic rod 5 retracts, causing the transparent protective cover 6 to descend. When the transparent protective cover 6 descends, the limiting bolt 7 at the bottom of the transparent protective cover 6 rotates and is clamped by the spring 9, which drives the pressure plate 8 to press against the top of the casting, thereby pressing and stabilizing the casting on the hollow bracket 201. Then, the motor 11 is started to drive the polishing disc 12 to rotate. With the toothed ring 2, which can rotate through the gear 3 and the rotating shaft 4, the casting can be polished in multiple directions. Under the protection of the transparent protective cover 6 and the transparent protective plate 10, the debris generated during polishing can be blocked and fall below the worktable 1 through the hollow bracket 201, avoiding the problem of debris splashing during polishing and facilitating later cleaning.
