Description

Technical Field

[0001] This utility model relates to the field of volute shell processing technology, specifically a burr removal and polishing device for volute shell processing. Background Technology

[0002] A volute is a helical mechanical component widely used in fluid machinery such as pumps and fans. Its unique helical flow channel design effectively guides the smooth flow of fluid, converting the fluid's kinetic energy into pressure energy. During operation, the fluid enters from the center and flows along the helical channel of the volute, gradually decreasing in velocity and continuously increasing in pressure, thus achieving efficient energy conversion. The structural design of the volute directly affects the performance of the equipment. A reasonable volute shape can reduce fluid resistance and improve the efficiency and stability of the machinery, making it a key component for ensuring the normal operation of fluid machinery. However, existing deburring equipment still has certain problems in use:

[0003] For example, a vortex shell grinding device with application number 202221685796.5 has the following technical solution: it includes a main frame, a device body, and a slide groove. A dust collection structure is slidably connected to the inner surface of the slide groove. The dust collection structure includes a first magnet slidably connected to the inner surface of the slide groove. A second magnet is connected to the main frame through the first magnet. A hollow shell is connected to the outer surface of the second magnet. By setting the dust collection structure, this utility model can collect and process metal debris. Existing clamping technologies mostly adopt fixed or single-angle clamping methods, which are difficult to meet the complex curved surface and diversified processing needs of vortex shells. When cutting, grinding, or inspecting different parts of the vortex shell, traditional clamps cannot quickly achieve multi-angle adjustment and cannot achieve flexible multi-angle clamping of the vortex shell.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing burr removal equipment. Utility Model Content

[0006] The purpose of this invention is to provide a burr-removing and grinding device for volute machining, so as to solve the problem of insufficient clamping effect in volute grinding mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A deburring and grinding device for machining volutes includes a movable base and a grinding base. A movable frame is mounted on top of the movable base, and a clamping platform is mounted on top of the movable frame. The volute to be processed is mounted in the middle of the clamping platform. The grinding base is located behind the movable base, and a column is mounted on the right side of the grinding base. A third motor is mounted on the right side of the column, and a grinding disc is connected to the left output end of the third motor. Three sliding grooves are formed on the upper surface of the movable base, and the movable frame is located on the upper surface of the movable base to form a left-right moving structure. The clamping platform forms a rotating structure, and a sliding groove is formed on the upper surface of the clamping platform. A first clamping block and a second clamping block are slidably connected inside the sliding groove. The first clamping block forms a clamping structure on the left and right outer sides of the volute, and the second clamping block forms a clamping structure on the left and right inner sides of the volute.

[0009] Preferably, a first motor is provided on the left side of the movable base, and a first threaded rod is connected and installed on the right output end of the first motor, and the right side of the first threaded rod is rotatably connected to the right side of the inside of the movable base.

[0010] By adopting the above technical solution, the first motor and the first threaded rod on the left side of the moving base are moved. The first motor drives the first threaded rod to rotate, which can precisely control the left and right movement of the moving frame, so that the relative position of the volute to be processed and the grinding disc can be flexibly adjusted, which is convenient for grinding burrs at different positions of the volute.

[0011] Preferably, a movable block is threadedly connected to the outer side of the first threaded rod, and the movable block is fixedly installed in the middle of the bottom of the movable frame. Slider blocks are fixedly installed on both the front and rear sides of the bottom of the movable frame, and slide rods pass through the left and right sides of the sliders, and the slide rods are fixedly installed on the front and rear sides inside the movable base.

[0012] By adopting the above technical solution, the moving block on the outer side of the first threaded rod, the slider and the slide rod at the bottom of the moving frame, the moving block moves with the rotation of the first threaded rod, and drives the moving frame to slide smoothly on the slide rod, ensuring the stability of the moving frame, thereby ensuring the stability of the volute position during the grinding process and improving the grinding accuracy.

[0013] Preferably, a second motor is fixedly installed above the movable frame, and the output end of the second motor is connected to the middle position of the bottom of the clamping platform.

[0014] By adopting the above technical solution, the second motor above the moving frame drives the clamping table to rotate, so that the volute clamped on the clamping table can rotate at multiple angles, which facilitates the grinding of the surface of the volute at different angles and improves the equipment's adaptability to grinding the complex curved surface of the volute.

[0015] Preferably, a first rotating handle is provided on the lower right side of the clamping platform, and a second threaded rod is connected and installed on the left side of the first rotating handle. The threads on the left and right sides of the second threaded rod are opposite, and the first clamping block is threadedly connected to the left and right sides of the outer side of the second threaded rod.

[0016] By adopting the above technical solution, the first rotating handle, the second threaded rod, and the first clamping block on the lower right side of the clamping platform can be adjusted by rotating the first rotating handle to make the second threaded rod rotate, thereby causing the first clamping block to move towards or away from each other. This can adjust the clamping force and position on the outside of the vortex shell according to the size of the vortex shell, thus enhancing the clamping effect on the outside of the vortex shell.

[0017] Preferably, a second rotating handle is provided on the upper left side of the clamping platform, and a third threaded rod is connected and installed on the right side of the second rotating handle. The threads on the left and right sides of the third threaded rod are opposite, and the second clamping block is threadedly connected to the left and right sides of the outer side of the third threaded rod.

[0018] By adopting the above technical solution, the second rotating handle, the third threaded rod, and the second clamping block are located on the upper left side of the clamping platform. Rotating the second rotating handle drives the third threaded rod to rotate, thereby adjusting the position of the second clamping block and achieving stable clamping of the inside of the vortex shell. In conjunction with the first clamping block, the overall clamping firmness of the vortex shell is further improved.

[0019] Preferably, the third threaded rod passes through the lower left and right sides of the first clamping block, and the second clamping block is located inside the two first clamping blocks.

[0020] By adopting the above technical solution, the third threaded rod passes through the first clamping block and the positional relationship between the second clamping block and the first clamping block, which ensures the coordination between the first clamping block and the second clamping block when clamping the volute, so that the volute remains stable during the grinding process and prevents the volute from shaking or displacing in the clamping state.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the burr removal and grinding equipment for volute machining,

[0022] 1. Securely clamp the volute: The first and second clamping blocks clamp the volute from both the inside and outside. With the adjustable threaded rod structure, it can be flexibly adjusted according to the size and shape of the volute, firmly fixing the volute and preventing it from shaking or shifting during the grinding process, thus ensuring grinding accuracy.

[0023] 2. Enables multi-angle grinding: The left and right movement of the moving frame and the rotation of the clamping table allow the volute to be adjusted in all directions. Combined with the grinding disc, it can grind various surfaces and complex curved surfaces of the volute, improving the comprehensiveness and efficiency of grinding. Attached Figure Description

[0033] A first motor 2 is installed on the left side of the movable base 1, and a first threaded rod 3 is connected to the output end of the first motor 2 on the right side.

Slider blocks 5 are fixedly installed on the front and rear sides of the bottom of the movable frame 8, and slide rods 6 pass through the left and right sides of the sliders 5. The slide rods 6 are fixedly installed on the front and rear sides of the inside of the movable base 1. The first motor 2 and the first threaded rod 3 on the left side of the movable base 1 drive the first threaded rod 3 to rotate, which can precisely control the left and right movement of the movable frame 8, so that the relative position of the volute to be processed and the grinding disc 20 can be flexibly adjusted, which is convenient for grinding burrs at different positions of the volute. The moving block 4 on the outside of the first threaded rod 3, the slider 5 and the slide rod 6 at the bottom of the movable frame 8, the moving block 4 moves with the rotation of the first threaded rod 3, and drive the movable frame 8 to slide smoothly on the slide rod 6, ensuring the stability of the movement of the movable frame 8, thereby ensuring the stability of the position of the volute during the grinding process and improving the grinding accuracy.

[0034] A second motor 9 is fixedly installed above the moving frame 8, and the output end of the second motor 9 is connected to the middle position of the bottom of the clamping table 10.

The second rotating handle 14, the third threaded rod 15, and the second clamping block 16 are located on the upper left side of the clamping platform 10. Rotating the second rotating handle 14 causes the third threaded rod 15 to rotate, thereby adjusting the position of the second clamping block 16 and achieving stable clamping of the inside of the volute. In conjunction with the first clamping block 13, it further improves the overall clamping firmness of the volute. The third threaded rod 15 passes through the first clamping block 13 and the positional relationship between the second clamping block 16 and the first clamping block 13, ensuring the synergy of the first clamping block 13 and the second clamping block 16 when clamping the volute, keeping the volute stable during the grinding process and preventing the volute from shaking or shifting in the clamping state.

[0036] Working principle:

[0037] In use, the volute to be processed is placed on the clamping table 10. Rotating the first handle 11 causes the second threaded rod 12 to rotate. Since the threads on the left and right sides of the second threaded rod 12 are opposite, the first clamping block 13 moves towards or away from it, thereby adjusting the clamping force and position on the outside of the volute. Simultaneously, rotating the second handle 14 causes the third threaded rod 15 to rotate. Since the threads on the left and right sides of the third threaded rod 15 are opposite, the second clamping block 16 moves accordingly, clamping the inside of the volute and ensuring it is firmly fixed. The second motor is then started. 9. The second motor 9 drives the clamping table 10 to rotate, adjusting the volute to a suitable angle. Based on the position of the burrs on the volute, the first motor 2 is started. The first motor 2 drives the first threaded rod 3 to rotate, which in turn drives the moving block 4 to move. The moving block 4 drives the moving frame 8 to slide left and right on the slide rod 6, moving the volute to a suitable relative position with the grinding disc 20. The third motor 19 is then started, driving the grinding disc 20 to rotate and polish the burrs on the volute. During the polishing process, the angle and position of the volute can be adjusted again according to the actual situation to ensure that the burrs on the volute are polished thoroughly and accurately.
