Description

Technical Field

[0001] This utility model relates to the technical field of pump body casting and grinding, specifically to a surface burr grinding device for pump body casting. Background Technology

[0002] Currently, water pumps are machines that transport or pressurize liquids. They transfer the mechanical energy of a prime mover or other external energy to the liquid, increasing its energy. They are mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Technical parameters of water pump performance include flow rate, suction head, discharge head, shaft power, water power, and efficiency. Based on different working principles, they can be classified into positive displacement pumps, centrifugal pumps, etc. However, burrs are generated during the pump body casting process. These burrs not only affect the appearance but may also affect the pump's performance and reliability. Therefore, removing these burrs is an important step in the pump body manufacturing process.

[0003] For example, in the prior art, Chinese patent authorization number CN220839622U, application date: 2023-10-11, entitled "A Pump Body Burr Grinding Device," relates to the field of water pump casing casting and grinding technology. It includes an inclined base plate, a grinding structure mounted on the inclined base plate, and the grinding structure comprising a fixed vertical plate, a rotating rod, a grinding outer frame, a fixing bracket, and a bearing ring. The bottom of the outer wall of the fixed vertical plate is fixedly mounted on the inclined base plate, the outer wall of the rotating rod is rotatably embedded within the fixed vertical plate, and one end of the outer wall of the rotating rod is fixedly mounted on the grinding outer frame. Through the grinding outer frame, fixing bracket, bearing ring, and partition plate, grinding particles inside the grinding outer frame can be used to perform comprehensive grinding of the pump body. The particles inside the grinding outer frame rub against the pump body to remove burrs and perform friction grinding of the pump body's interior. The fixed base plate, telescopic rod, and sliding arm make grinding more convenient and also facilitate the replacement of grinding particles, allowing for the use of particles of different sizes for detailed grinding of the pump body.

[0004] However, the above-mentioned patent still has shortcomings. When grinding and deburring the pump body, the pump body surface contains dirt and oxide scale, which makes it time-consuming for the grinding particles to remove dirt and oxide scale. This further reduces the working efficiency of deburring the pump body and cannot guarantee the gloss of the grinding.

[0005] Therefore, we propose a surface burr removal device for pump body casting. Utility Model Content

[0006] The purpose of this invention is to provide a surface burr removal device for pump body casting, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a surface burr grinding device for pump body casting, including a fixed frame, a cylinder fixedly connected to the back of the fixed frame, a concave connecting plate fixedly connected to the output end of the cylinder, a support plate fixedly connected to the bottom of the concave connecting plate, a deburring mechanism rotatably connected to one side of the support plate via a bearing, a servo motor fixedly connected to the other side of the support plate, the output end of the servo motor fixedly connected to the end of the deburring mechanism, and a cleaning pool provided inside the fixed frame, with the deburring mechanism located inside the cleaning pool.

[0008] Furthermore, the deburring mechanism includes a grinding cylinder that rotates on the side wall of the support plate via a bearing. A sealing door is rotatably connected to the top of the grinding cylinder via a hinge. Multiple drainage holes are provided on the surfaces of both the grinding cylinder and the sealing door.

[0009] Furthermore, an annular reinforcing plate is fixedly connected inside the grinding cylinder, and the end of the annular reinforcing plate penetrates into the interior of the grinding cylinder and extends outward.

[0010] Furthermore, the surface of the annular reinforcing plate is provided with multiple through slots, which are arranged in a circumferential array on the surface of the annular reinforcing plate.

[0011] Furthermore, a support base is fixedly connected inside the cleaning pool, and an auxiliary roller is rotatably connected inside the support base via a bearing. The surface of the annular reinforcing plate rotates on the auxiliary roller.

[0012] Furthermore, a drain pipe is fixedly connected to one side of the fixed frame, and a control valve is fixedly connected to the surface of the drain pipe.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] This invention allows the deburring mechanism to be located inside the cleaning tank, enabling the pump body to be immersed in the metal cleaning liquid inside the tank. This design achieves the cleaning of dirt and oxide scale from the pump body surface, preventing the time-consuming process of removing dirt and oxide scale with abrasive particles, further improving the deburring efficiency of the pump body, and ensuring the gloss of the polishing.

[0015] This utility model, through the cooperation of the cylinder, concave connecting plate and support plate, enables the deburring mechanism to be adjusted up and down. This design allows the pump body to be adjusted up and down, thereby improving the operation of the deburring mechanism and preventing the pump body from being cumbersome to handle in the metal cleaning liquid, further simplifying the operation of the deburring device.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5This utility model provides a technical solution: a surface burr grinding device for pump body casting, including a fixed frame 1, a cylinder 2 fixedly connected to the back of the fixed frame 1, a concave connecting plate 3 fixedly connected to the output end of the cylinder 2, a support plate 4 fixedly connected to the bottom of the concave connecting plate 3, a deburring mechanism 5 rotatably connected to one side of the support plate 4 via a bearing, a servo motor 6 fixedly connected to the other side of the support plate 4, and the output end of the servo motor 6 fixedly connected to the end of the deburring mechanism 5. A cleaning pool 7 is provided inside the fixed frame 1, and the deburring mechanism 5 is located inside the cleaning pool 7. Notches are provided on both sides of the fixed frame 1 to facilitate the up and down adjustment of the deburring mechanism 5. A sealing gasket is provided on the inner side of the support plate 4 so that it can be just locked inside the notch, preventing the metal cleaning liquid from overflowing through the notch when the deburring mechanism 5 rotates.

[0025] according to Figure 3 It is known that the deburring mechanism 5 includes a grinding cylinder 51 that rotates on the side wall of the support plate 4 via a bearing. The top of the grinding cylinder 51 is rotatably connected to a sealing door 52 via a hinge. Both the grinding cylinder 51 and the sealing door 52 have multiple drainage holes 53. The opening of the grinding cylinder 51 makes it easy to insert the pump body, and then close it through the sealing door 52 to prevent the grinding particles from separating from the pump body when the grinding cylinder 51 rotates. The opening of the drainage holes 53 also makes it easy for metal cleaning liquid to be poured into the interior of the grinding cylinder 51 to assist the grinding particles in better grinding and deburring the pump body.

[0026] according to Figure 3 It is known that an annular reinforcing plate 54 is fixedly connected inside the grinding cylinder 51. The end of the annular reinforcing plate 54 penetrates into the interior of the grinding cylinder 51 and extends outward. With the setting of the annular reinforcing plate 54, the interior of the grinding cylinder 51 can be divided into several chambers, so that multiple sets of pump bodies can be inserted at the same time. Furthermore, the annular reinforcing plate 54 penetrates into the interior of the grinding cylinder 51, thereby strengthening the overall robustness of the grinding cylinder 51.

[0027] according to Figure 4 It is known that the surface of the annular reinforcing plate 54 is provided with multiple through grooves 55, which are arranged in a circumferential array on the surface of the annular reinforcing plate 54. With the opening of multiple through grooves 55, it is convenient for the grinding particles inside the grinding cylinder 51 to flow, thereby facilitating better grinding and deburring of the pump body in different chambers.

[0028] according to Figure 4It is known that a support base 8 is fixedly connected inside the cleaning pool 7, and an auxiliary roller 9 is rotatably connected inside the support base 8 through a bearing. The surface of the annular reinforcing plate 54 rotates on the auxiliary roller 9. Multiple auxiliary rollers 9 can be rotated through the support base 8, so that the annular reinforcing plate 54 is located above the auxiliary roller 9, so that it can play an auxiliary support role when the grinding cylinder 51 rotates, and at the same time ensure the stability during rotation.

[0029] according to Figure 4 and Figure 5 It can be seen that a drain pipe 10 is fixedly connected to one side of the fixed frame 1, and a control valve is fixedly connected to the surface of the drain pipe 10. With the drain pipe 10 set, it can be used to periodically discharge the metal cleaning liquid inside the cleaning tank 7, so as to facilitate the replacement of new metal cleaning liquid and refilling it into the cleaning tank 7 for use. With the control valve set, the drain pipe 10 can be opened and closed.

[0030] The working principle of this utility model is as follows: In use, the cylinder 2 on one side of the fixed frame 1 is first driven to raise the concave connecting plate 3 and the fixed support plate 4. While the support plate 4 is rising, the deburring mechanism 5 and the servo motor 6 are simultaneously moved upward, so that the deburring mechanism 5 can be disengaged into the cleaning tank 7. At this time, different grinding particles can be put into the deburring mechanism 5 according to the grinding precision of the pump body, and the pump body is placed into the deburring mechanism 5. Then, the cylinder 2 is driven downward to immerse the deburring mechanism 5 into the cleaning tank 7. At this time, the servo motor 6 is driven to rotate the deburring mechanism 5. When the deburring mechanism 5 rotates, the grinding particles and the pump body are simultaneously rubbed together to achieve the deburring effect. In addition, the metal cleaning liquid in the cleaning tank 7 can better remove the burrs on the surface of the pump body while ensuring the polishing gloss.
