Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a multi-axis grinding device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Their varieties and specifications are quite numerous. In the production process of welded valves, the weld joints of the valves need to be ground and processed.

[0003] For example, a grinding device for valve production, disclosed in patent publication number CN213498382U, includes a grinding table. A valve is placed on top of the grinding table. Two grooves are formed on the top of the grinding table, and clamping plates are slidably installed in each groove. The sides of the two clamping plates that are close to each other are in contact with the valve. Two cylinders are fixedly installed on the top of the grinding table, and a common top plate is fixedly connected to the output shafts of the two cylinders. A rotating hole is formed on the top of the top plate, and a connecting rod is rotatably installed in the rotating hole. A grinding disc is fixedly installed at the bottom end of the connecting rod. This device facilitates the restriction of the valve's position and can collect the grinding debris, without affecting the working environment.

[0004] However, during the use of the above-mentioned equipment, due to the setting of its internal grinding table, it is inconvenient to quickly adjust the grinding position and angle when the valve castings usually have complex shapes and contours, which reduces work efficiency. Therefore, in order to address this situation, we propose a more convenient and practical multi-axis grinding equipment to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a multi-axis grinding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-axis grinding device, including a worktable, on the top of which are sequentially arranged a drive assembly, a grinding mechanism for grinding valve castings, and a dust collection mechanism for filtering and grinding debris generated during the grinding process; The grinding mechanism includes two mounting plates. A through hole is opened in the center of the top of the mounting plate. A rotating shaft is rotatably connected in the through hole. A rotating frame is fixedly connected to one end of the rotating shaft, and a first spur gear is fixedly connected to the other end. A second spur gear is rotatably connected to one side of the top of the mounting plate. The teeth of the first spur gear and the second spur gear mesh with each other. A grinding motor is provided on one side of the rotating frame, and a grinding rod is installed at the output end of the grinding motor.

[0007] Furthermore, the drive assembly includes a symmetrically arranged first slide rail connected to the worktable, a first slider slidably connected to the top of the first slide rail, a second slide rail mounted on the top of the first slider, and a second slider slidably connected to the top of the second slide rail.

[0008] Furthermore, a third slide rail is installed on one side of the top of the second slider, and a third slider is slidably connected to one side of the third slide rail. The third slider is connected to the mounting plate.

[0009] Furthermore, a through hole is rotatably connected to one side of the rotating frame, and a connecting shaft is rotatably connected inside the through hole. A rotating block is fixedly connected to one end of the connecting shaft, and the rotating block is connected to the grinding motor. A first bevel gear is fixedly connected to the other end of the connecting shaft. A second bevel gear is rotatably connected to one side of the rotating block, and the teeth of the second bevel gear and the first bevel gear mesh with each other.

[0010] Furthermore, the dust collection mechanism includes a filter box, which is connected to the second slide rail. The filter box has multiple equidistant slots on one side, and filter plates are inserted into the slots.

[0011] Furthermore, a flexible hose is fixedly connected to the center of the top of the filter box, and a dust collection funnel is fixedly connected to one end of the hose. The dust collection funnel is connected to the mounting plate, and a negative pressure motor is installed in the center of the bottom of the filter box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This multi-axis grinding equipment, through the setup of a grinding mechanism and a dust extraction mechanism, operates as follows: First, the drive assembly moves the entire grinding mechanism, precisely positioning the grinding rod to the grinding position on the valve casting. Then, the grinding motor starts, driving the grinding rod to rotate and grind the valve casting. Simultaneously, the motor drives the first spur gear to rotate, which in turn drives the second spur gear and the rotating shaft to rotate, thereby changing the angle of the rotating frame and allowing the grinding rod to grind the casting from different angles. Finally, the motor drives the first bevel gear to rotate, which in turn drives the second bevel gear and the connecting shaft to rotate, further fine-tuning the angle of the grinding rod. This device allows the grinding equipment to better conform to these complex surfaces for grinding, ensuring that all parts receive uniform grinding treatment, improving grinding quality, and demonstrating strong practicality, making it suitable for widespread application.

[0013] At the same time, the vacuuming mechanism can effectively filter out debris in the air, expel clean air, prevent debris from spreading in the air, and improve the working environment. Attached Figure Description

[0016] 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.

[0017] Grinding equipment is required in valve processing. The grinding equipment provided by this invention is specifically designed for grinding valve castings during valve manufacturing. When using this equipment, it is essential to wear appropriate personal protective equipment, such as safety glasses, masks, and gloves, to prevent injury to the eyes, skin, and respiratory tract from flying debris. The rotation speed and feed rate of the grinding mechanism 8 should be adjusted appropriately according to the material, shape, and grinding requirements of the valve casting. Excessive rotation speed or feed rate should be avoided to prevent over-grinding or damage to the casting surface. After using the grinding equipment, it must be thoroughly cleaned and maintained to ensure it is in good working order.

[0018] like Figures 1-3As shown, this utility model provides a technical solution: a multi-axis grinding device, including a worktable 1. A drive assembly, a grinding mechanism 8 for grinding valve castings, and a dust extraction mechanism 9 for filtering and grinding debris are sequentially arranged on the top of the worktable 1. The grinding mechanism 8 includes two mounting plates 801. A through hole is opened in the center of the top of the mounting plate 801, and a rotating shaft 802 is rotatably connected within the through hole. A rotating frame 805 is fixedly connected to one end of the rotating shaft 802, and a first spur gear 803 is fixedly connected to the other end. A second spur gear 804 is rotatably connected to one side of the top of the mounting plate 801. The first spur gear 804... 03 and the teeth of the second spur gear 804 mesh with each other. A grinding motor 810 is provided on one side of the rotating frame 805. A grinding rod 811 is installed at the output end of the grinding motor 810. The drive assembly includes a first slide rail 2 arranged symmetrically. The first slide rail 2 is connected to the worktable 1. A first slider 3 is slidably connected to the top of the first slide rail 2. A second slide rail 4 is installed on the top of the first slider 3. A second slider 5 is slidably connected to the top of the second slide rail 4. A third slide rail 6 is installed on one side of the top of the second slider 5. A third slider 7 is slidably connected to one side of the third slide rail 6. The third slider 7 is connected to the mounting plate 801.

[0019] like Figure 2 As shown, a through hole is rotatably connected to one side of the rotating frame 805, and a connecting shaft 806 is rotatably connected inside the through hole. A rotating block 807 is fixedly connected to one end of the connecting shaft 806, and the rotating block 807 is connected to the grinding motor 810. A first bevel gear 808 is fixedly connected to the other end. A second bevel gear 809 is rotatably connected to one side of the rotating block 807, and the teeth of the second bevel gear 809 and the first bevel gear 808 mesh with each other.

[0020] It should be noted that during use, the drive assembly first moves the grinding mechanism 8 as a whole, precisely positioning the grinding rod 811 to the position to be ground on the valve casting. Then, the grinding motor 810 starts, driving the grinding rod 811 to rotate and grind the valve casting. At the same time, the motor drives the first spur gear 803 to rotate, which in turn drives the second spur gear 804 and the rotating shaft 802 to rotate, thereby changing the angle of the rotating frame 805, allowing the grinding rod 811 to grind the casting from different angles. Finally, the motor drives the first bevel gear 808 to rotate, which in turn drives the second bevel gear 809 and the connecting shaft 806 to rotate, further fine-tuning the angle of the grinding rod 811. The grinding mechanism 8 can precisely control the position and angle of the grinding rod 811, making the grinding process more accurate.

[0021] like Figure 3As shown, the vacuuming mechanism 9 includes a filter box 901, which is connected to the second slide rail 4. The filter box 901 has multiple equally spaced slots on one side, and filter plates 902 are inserted into the slots. A flexible hose 903 is fixedly connected to the center of the top of the filter box 901. A vacuum funnel 904 is fixedly connected to one end of the flexible hose 903. The vacuum funnel 904 is connected to the mounting plate 801. A negative pressure motor 905 is installed at the center of the bottom of the filter box 901.

[0022] It should be noted that during use, the grinding debris is drawn into the hose 903 through the suction funnel 904 by the negative pressure motor 905. The debris then enters the filter box 901 with the airflow. The filter plate 902 in the filter box 901 filters the airflow, trapping the debris inside the filter box 901, while clean air is discharged. The dust collection mechanism 9 can effectively filter out debris in the air and discharge clean air, preventing debris from spreading in the air and improving the working environment.

[0023] During operation, the grinding rod 811 is precisely positioned to the grinding location on the valve casting by the coordinated action of the first slide rail 2, first slider 3, second slide rail 4, second slider 5, third slide rail 6, and third slider 7 of the drive assembly. Then, the grinding motor 810 starts, driving the grinding rod 811 to rotate and grind the valve casting. Simultaneously, the motor drives the first spur gear 803 to rotate, which in turn drives the second spur gear 804 and the rotating shaft 802 to rotate, thereby changing the angle of the rotating frame 805. This allows the grinding rod 811 to grind the casting from different angles. Finally, the motor drives the first spur gear 803 to rotate, which in turn drives the second spur gear 804 and the rotating shaft 802 to rotate, thus changing the angle of the rotating frame 805. A bevel gear 808 rotates, driving a second bevel gear 809 and a connecting shaft 806 to rotate, further fine-tuning the angle of the grinding rod 811. The grinding debris generated is sucked into the hose 903 through the dust collection funnel 904 under the action of the negative pressure motor 905. The debris enters the filter box 901 with the airflow. The filter plate 902 in the filter box 901 filters the airflow, trapping the debris inside the filter box 901, while clean air is discharged. This device enables the grinding equipment to better fit these complex surfaces for grinding, ensuring that all parts receive uniform grinding treatment and improving the grinding quality.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
