Description

Technical Field

[0001] This utility model relates to the technical field of burr removal devices, and in particular to a burr removal device for shell casting. Background Technology

[0002] In the field of mechanical manufacturing, shell-type parts are mostly produced using casting processes. However, during the casting process, due to factors such as mold closing gaps, the impact of molten metal flow, and residual gates, burrs and flash are easily generated on the surface and edges of the shell. Burr removal devices can efficiently clean burrs, ensuring the precision and quality of the shell and laying the foundation for subsequent processing and assembly. They are indispensable equipment in casting production. Traditional burr removal devices mostly use a fixed grinding structure, with the position and angle of the grinding belt or grinding head fixed. They can only be adapted to housings of a single shape or size. When faced with irregularly shaped housings (such as housings with grooves, protrusions, or corners) or housings of different sizes, the position and angle of the grinding components cannot be adjusted, making it difficult to clean burrs in some corners and crevices, resulting in grinding blind spots.

[0015] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0016] To address the problems existing in the background art, this application proposes the following technical solution: a burr removal device for shell casting, comprising a base 1, a frame 2 fixedly connected to the base 1, multiple sets of drive rollers 3 and multiple sets of first guide rollers 4 rotatably connected to the outside of the frame 2, an adjusting frame 6 provided outside the frame 2, a third guide roller rotatably connected to the outside of the adjusting frame 6, a drive motor 21 fixedly connected to the outside of the frame 2, the output end of the drive motor 21 fixedly connected to the drive rollers 3, a grinding belt 5 sleeved on the outside of the drive rollers 3, first guide rollers 4, second guide rollers 7 and third guide rollers, an adjusting assembly for the grinding belt 5 also provided outside the frame 2, and a clamping and conveying assembly provided on the base 1. An adjusting motor 8 fixedly connected to the outside of the frame 2, the output end of the adjusting motor 8 fixedly connected to the adjusting frame 6. The drive roller 3 on the frame 2 provides power to the grinding belt 5 under the drive motor 21, so that the grinding belt 5 is continuously driven to achieve continuous grinding of the shell, replacing manual hand-held grinding tools, greatly improving deburring efficiency and reducing labor intensity. The first guide roller 4, the second guide roller 7, and the third guide roller work together to guide and tension the grinding belt 5, ensuring smooth transmission of the grinding belt 5 and preventing uneven grinding caused by deviation or loosening. The adjusting frame 6 works in conjunction with the adjusting motor 8. When grinding specific corners of the housing, the adjusting motor 8 drives the adjusting frame 6 to rotate and release the grinding belt 5, reserving working space for the contact roller 11 of the grinding belt 5 adjusting assembly. This allows the grinding belt 5 to smoothly form a V-shaped angle, adapting to corner grinding needs. The grinding belt 5 adjusting assembly can change the shape of the grinding belt 5, while the clamping and conveying assembly achieves precise positioning and conveying of the housing. Together, they ensure that burrs on housings of different structures can be effectively removed, solving the problem that traditional devices can only grind flat surfaces and are difficult to handle corner burrs. The grinding belt 5 adjustment assembly includes a first electric push rod 9 and an abutment roller 11. The first electric push rod 9 is fixedly connected to the outside of the frame 2, and the output end of the first electric push rod 9 is fixedly connected to a mounting base 10. The abutment roller 11 is rotatably connected to the outside of the mounting base 10. The adjustment component of the polishing belt 5 is the key to deburring special corners of the housing. The first electric push rod 9 can precisely control the extension and retraction distance of the mounting base 10. Combined with the usage method, it pushes the contact roller 11 to move towards the polishing belt 5, which can form a stable contact force on the polishing belt 5, causing the polishing belt 5 to be locally concave to form a V-shaped angle, which can adapt to special areas such as the edges and gaps of the housing, and solve the problem that traditional polishing belts 5 cannot fit the corners and leave burrs. Mounting base 10 provides a stable mounting foundation for the contact roller 11, ensuring that the contact roller 11 does not wobble when it contacts the grinding belt 5, thus guaranteeing a stable V-angle shape and resulting in a uniform grinding effect. The contact roller 11 is rotatably connected to the mounting base 10 and can rotate synchronously with the grinding belt 5, converting the sliding friction between the contact roller 11 and the grinding belt 5 into rolling friction, reducing wear on both and extending the service life of the components. It also prevents the grinding belt 5 from jamming due to excessive friction, ensuring a continuous and smooth grinding process. This electric adjustment method eliminates the need for manual adjustment, is convenient to operate, and offers high adjustment precision. It allows for flexible control of the V-angle angle according to the size of the housing corners, improving the adaptability of the device to different housings. A fixed frame 12 is fixedly connected to the base 1. An adjusting seat 14 is provided on the outside of the fixed frame 12, and a fixed seat 16 is provided on the outside of the adjusting seat 14. The clamping and conveying assembly includes a bidirectional threaded rod 18, a second electric push rod 13, and a third electric push rod 15. The second electric push rod 13 is fixedly connected to the outside of the fixed frame 12, and its output end is fixedly connected to the adjusting seat 14. The third electric push rod 15 is fixedly connected to the outside of the adjusting seat 14, and its output end is fixedly connected to the fixed seat 16. The fixed seat 16 has a mounting groove 17, and the bidirectional threaded rod 18 is rotatably connected to the mounting groove 17. Two nut blocks 20 are threadedly connected to the outside of the bidirectional threaded rod 18, and a clamping plate 22 is fixedly connected to the outside of the nut blocks 20. The clamping plate 22 has a V-shaped structure. A handwheel 19 is fixedly connected to the top of the bidirectional threaded rod 18. The clamping and conveying assembly achieves precise positioning of the housing through multi-dimensional adjustment. The fixed frame 12 provides installation support for the adjustment seat 14. The second electric push rod 13 drives the adjustment seat 14 to move laterally. Combined with the usage method, the housing can be pushed closer to or further away from the grinding belt 5, precisely controlling the distance between the housing and the grinding belt 5 to ensure that the grinding force is moderate and to avoid the housing being over-grinded due to being too close or the burrs not being removed due to being too far away. The third electric push rod 15 drives the fixed base 16 to move up and down, adjusting the grinding position according to the height of the housing, adapting to housings of different thicknesses, without the need to replace clamping components, thus improving the versatility of the device. When the bidirectional threaded rod 18 inside the fixed base 16 rotates, it can drive the two nut blocks 20 to move in opposite directions, thereby allowing the clamping plate 22 to clamp or loosen. The handwheel 19 is designed so that the operator can rotate the threaded rod without tools, making operation convenient. The V-shaped clamping plate 22 has a high degree of contact with the outer surface of the housing, which can form a stable clamping of the housing from both sides, preventing the housing from shifting during grinding, and avoiding the deformation of the housing caused by concentrated clamping force, thus solving the problem of slippage and damage to the housing caused by traditional flat plate clamping. The usage method of this embodiment is as follows: Place the cast housing that needs to be deburred between the two V-shaped clamping plates 22 of the fixed base 16; turn the handwheel 19 at the top of the double-threaded rod 18 by hand, so that the double-threaded rod 18 rotates in the mounting groove 17, and the two nut blocks 20 move towards each other through the thread transmission, thereby driving the clamping plates 22 to move closer together until the clamping plates 22 are tightly attached to the surface of the housing, firmly clamping the housing and ensuring that the housing will not shift during the grinding process. Start the drive motor 21, which drives the drive roller 3 to rotate. The drive roller 3 drives the grinding belt 5 through friction with the grinding belt 5. At the same time, the first guide roller 4, the second guide roller 7 and the third guide roller cooperate to guide and tension the grinding belt 5 to ensure that the grinding belt 5 runs smoothly. Start the second electric push rod 13 to push the adjusting seat 14 to move laterally along the fixed frame 12, which drives the fixed seat 16 and the housing to approach the grinding belt 5 until the surface of the housing to be ground is in initial contact with the grinding belt 5. Start the third electric push rod 15 to drive the fixed seat 16 to move up and down, finely adjust the height of the housing, and make the grinding belt 5 accurately aligned with the burr area of ​​the housing. The grinding belt 5 continuously drives the machine to grind and remove conventional burrs from the surface of the housing. During the process, the contact force between the housing and the grinding belt 5 can be slowly adjusted by the second electric push rod 13 to ensure that the burrs are removed cleanly without damaging the housing. If there are burrs in special corners such as edges and gaps in the housing, the first electric push rod 9 is activated to push the mounting base 10 and the contact roller 11 toward the grinding belt 5, so that the contact roller 11 contacts the grinding belt 5 to form a V-shaped angle. At the same time, the adjusting motor 8 is activated to drive the adjusting frame 6 to rotate and release the grinding belt 5, ensuring that the contact roller 11 can fully contact the grinding belt 5, so that the V-shaped angle fits the corner of the housing, completing the burr grinding in special areas.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
