Description

Technical Field

[0001] This utility model relates to the field of hardware polishing technology, specifically a device for processing burrs and polishing hardware parts. Background Technology

[0002] During the production and processing of cast iron hardware, burrs are often unavoidably generated on the surface of the workpiece due to the characteristics of the casting process and the mechanical contact involved in the processing. These burrs not only affect the appearance quality of the product, but may also cause a decrease in fitting accuracy in subsequent assembly stages, and even pose safety hazards. Therefore, the grinding and repair of burrs has become a crucial process in the production of cast iron hardware.

[0003] Currently, for the burr removal of small cast iron hardware parts, the industry mostly uses automated equipment in conjunction with robotic arms. Taking a common right-angle cast iron pipe elbow as an example, after the robotic arm fixes the workpiece through a clamping mechanism, it drives the workpiece to move downwards according to a preset program, so that the part to be ground precisely fits the surface of the grinding wheel or abrasive. With the help of the high-speed rotation of the abrasive, the burr removal can be completed quickly. This method has shown high efficiency and stability in the mass production of standardized right-angle workpieces.

[0004] However, with the diversification of market demand, customers' requirements for the angles of cast iron hardware are becoming increasingly flexible. A large number of non-fixed-angle cast iron workpieces (such as obtuse-angle pipe elbows) are entering the production process. The angle parameters of these workpieces vary greatly depending on customer needs, no longer limited to traditional right-angle specifications. At this point, the limitations of existing grinding equipment become increasingly apparent: on the one hand, some grinding devices have fixed grinding wheel angles, only suitable for workpieces with specific angles, and cannot meet the grinding needs of non-fixed-angle workpieces, forcing these products to rely on manual operation. Manual operation is not only labor-intensive and inefficient, but also prone to uneven operating force and angle control deviations, affecting grinding quality and resulting in poor product consistency. On the other hand, a few devices attempt to adjust the workpiece angle using a robotic arm to adapt to a fixed-angle grinding belt, but this also has significant drawbacks: the robotic arm's angle adjustment requires complex program control, and parameters need to be readjusted every time a different angle specification is changed, significantly extending production preparation time and leading to a significant decrease in production efficiency. Meanwhile, robotic arms with high-precision angle adjustment capabilities are expensive. For small-batch, multi-variety non-fixed-angle cast iron workpiece processing, the equipment input-output ratio is unbalanced, making it difficult to promote and apply in small and medium-scale production scenarios.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A device for grinding and polishing burrs in the processing of hardware parts, comprising:

[0027] Frame 1 is a rigid support structure and includes vertical structural plates 2.

[0028] A grinding assembly is located on one side of the vertical structural plate 2. The grinding assembly includes a drive wheel 3, a driven wheel 4, and a grinding belt 5. The grinding belt 5 is sleeved on the outside of the drive wheel 3 and the driven wheel 4.

[0029] A stepless adjustment component with a limited range is located on the side of the driven wheel 4 facing away from the vertical structural plate 2. The device is very convenient to use. The position of the driven wheel 4 is adjusted according to the angle of the workpiece to be processed using the stepless adjustment component with a limited range, and then tightened with bolts after adjustment.

[0030] Furthermore, a drive wheel shaft 6 is fixedly installed at the center of the drive wheel 3, and a first bearing 7 is installed on the vertical structural plate 2 at the location corresponding to the drive wheel shaft 6. The drive wheel shaft 6 is fixedly connected to the inner ring of the first bearing 7, and the drive wheel 3 is rotatably connected to the vertical structural plate 2 through the first bearing 7. A drive motor 8 is fixedly installed on the side of the vertical structural plate 2 away from the drive wheel 3, and the drive motor 8 is coaxially fixedly connected to the drive wheel shaft 6.

[0031] Furthermore, the limited-range stepless adjustment component includes an adjustment plate 9, a second bearing 10, a driven wheel shaft 11, and a stepless adjustment track 12. The adjustment plate 9 is located on the side of the driven wheel 4 facing away from the vertical structural plate 2. The second bearing 10 is fixedly mounted on the adjustment plate 9, and the driven wheel shaft 11 is fixedly connected to the inner ring of the second bearing 10. The stepless adjustment track 12 is located on the vertical structural plate 2, and one end of the driven wheel shaft 11 passes through the stepless adjustment track 12 and is coaxially fixedly connected to the driven wheel 4. The driven wheel 4 can be adjusted along the stepless adjustment track 12, and the adjustment range is limited by the curvature of the stepless adjustment track 12. It is recommended that the adjustment range be set between 0-60°.

[0032] Furthermore, the stepless adjustment track 12 is in the shape of an arc hole, and the center of the stepless adjustment track 12 coincides with the center of the drive wheel shaft 6. The coincidence of the centers ensures that the entire driven wheel 4 is adjusted around the center of the drive wheel shaft 6, so that the distance between the driven wheel 4 and the drive wheel 3 remains constant, preventing the sanding belt 5 from being stretched or loosened.

[0033] Furthermore, two sets of arc-shaped fixing fittings 13 are provided on both sides of the vertical structural plate 2 corresponding to the stepless adjustment track 12. Multiple sets of first fixing holes 14 are opened on the two sets of arc-shaped fixing fittings 13. The arc-shaped fixing fittings 13 are mainly used to fix the adjustment angle. When the angle is adjusted to a suitable angle, bolts are passed through the first fixing holes 14, the arc-shaped fixing bolt holes 16 and the second fixing holes 15 in sequence. Tightening the bolts makes the arc-shaped fixing fittings 13 and the adjustment plate 9 tightly press against the vertical structural plate 2 to complete the fixation. The force applied to the workpiece during the grinding operation is small, and the grinding belt 5 can deform slightly according to the force, so the adjustment plate 9 will not loosen, and the bolts can meet the fixation requirements.

[0034] Furthermore, the adjusting plate 9 has a second fixing hole 15 corresponding to the first fixing hole 14.

[0035] Furthermore, two sets of arc-shaped fixing bolt holes 16 are provided on the vertical structural plate 2, and the two sets of arc-shaped fixing bolt holes 16 coincide with the rotation trajectory of the first fixing hole 14 around the center of the drive wheel shaft 6.

[0036] Furthermore, an arc-shaped groove 17 is provided on the side of the arc-shaped fixing bolt hole 16 near the driven wheel 4, and the arc-shaped fixing fitting 13 is slidably engaged in the arc-shaped groove 17. The arc-shaped groove 17 is used to retract the arc-shaped fixing fitting 13 inward, so as to avoid excessive gaps between the vertical structural plate 2 and the grinding assembly.

[0055] Working Principle: This hardware parts processing burr grinding device achieves efficient grinding of burrs on non-fixed angle cast iron workpieces through the coordinated operation of multiple components. The device is supported by a rigid frame 1, with a vertical structural plate 2 supporting a drive wheel 3 and a driven wheel 4. The drive wheel 3 is rotatably connected to a first bearing 7 on the vertical structural plate 2 via a drive wheel shaft 6. A drive motor 8 is fixed to the back of the vertical structural plate 2 and coaxially connected to the drive wheel shaft 6, driving the drive wheel 3 to rotate after being powered on. The drive wheel 3 and driven wheel 4 are linked by a grinding belt 5, forming a circular grinding area. The high-speed movement of the outer surface of the grinding belt cuts and polishes the burrs on the workpiece. The driven wheel 4 is connected to a second bearing 10 on an adjusting plate 9 via a driven wheel shaft 11. The driven wheel shaft 11 passes through an arc-shaped stepless adjustable track 12 on the vertical structural plate 2 centered on the drive wheel shaft 6, allowing the driven wheel 4 to move within a certain range while maintaining a constant distance from the drive wheel 3, ensuring stable tension of the grinding belt 5. After the operator adjusts the position of the driven wheel 4 according to the workpiece angle requirements, the angle is locked through the arc-shaped fixing fitting 13: the arc-shaped fixing fitting 13 on the vertical structural plate 2 is aligned with the second fixing hole 15 on the adjusting plate 9, and the bolt passes through the first fixing hole 14, the arc-shaped fixing bolt through hole 16 and the second fixing hole 15 in sequence. The arc-shaped fixing fitting 13 slides and locks in the arc groove 17, thus securing the adjusting plate 9 to the vertical structural plate 2. After the workpiece is placed in the grinding area, the drive motor 8 drives the sanding belt to rotate. The sanding belt slightly deforms according to the irregularity of the workpiece surface to achieve adaptive grinding. This design avoids the complex programming and high cost problems of traditional robot adjustment. By directly adjusting the sanding belt angle, the production preparation time is shortened. It is suitable for small-batch, multi-variety processing. The coincidence of the geometric centers of each component and the structural optimization ensure the adjustment accuracy and working stability. It can still maintain reliable operation under the force of the workpiece, providing an efficient burr removal solution for non-fixed angle cast iron workpieces.
