Description

Technical Field

[0001] This utility model relates to the field of metal material grinding, specifically to a metal material processing and grinding mechanism. Background Technology

[0002] Grinding of metal materials is a crucial surface treatment process in mechanical manufacturing and maintenance. Its purpose is to precisely remove burrs, oxide layers, welds, or excess material from the surface of a workpiece through grinding, in order to achieve specific dimensional accuracy, shape requirements, or a smooth surface finish.

[0003] The grinding wheel is rigidly connected to the power output end of the grinding machine through the connecting flange on the inner wall of its central hole. The high-speed torque of the grinding machine is transmitted to the grinding wheel without loss through the connecting flange, driving it to rotate at high speed. The high-speed rotating grinding wheel can then be used to grind metal materials.

[0004] Currently, most grinding wheels are fixed to their inner flanges using resin adhesive. This process aims to firmly integrate the two. However, this one-piece structure has significant drawbacks: the grinding wheel itself is a consumable, and its working layer will eventually fail due to continuous wear. When excessively worn, the entire assembly must be scrapped. Moreover, during replacement, the operator must laboriously remove the locking bolts on the connecting flange, a process that is not only cumbersome and time-consuming but also wastes the metal connecting flange, increasing operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a metal material processing and grinding mechanism. The design of the bushing allows for quick docking of the grinding wheel and the connecting flange, thus improving the convenience of grinding wheel installation. The engagement of the protrusion and groove allows the bushing and the connecting flange to rotate synchronously. The positioning shaft, in conjunction with the retaining hole, can limit the protrusion inside the groove, thereby axially limiting the connecting flange and the bushing, thus completing the installation of the connecting flange and the bushing. The sliding engagement of the collar with the inclined surface, the limiting spring, and the push plate allows the positioning shaft to move out of the retaining hole, thus quickly releasing the bushing's limitation and facilitating the disassembly of the grinding wheel. In this way, the grinding wheel can be replaced without disassembling the connecting flange, thereby solving the problems of increased operating costs due to the non-reusability of the connecting flange and the inconvenience of grinding wheel replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal material processing and grinding mechanism, comprising: A connecting flange connected to the output end of a grinding wheel, wherein a protrusion is fixedly connected to the outer wall of the connecting flange; A bushing, wherein a grinding wheel is fixedly connected to the outer wall of the bushing, and a groove matching the protrusion is provided on the inner wall of the bushing; The disassembly and assembly mechanism includes a push plate, which is slidably connected to the inner wall of the protrusion. A positioning shaft is fixedly connected through and to the inner wall of the push plate. A retaining hole for inserting the positioning shaft is provided in the inner wall of the groove. A limit spring is fixedly connected to the side wall of the push plate. A collar is slidably connected to the inner wall of the connecting flange. An inclined surface is provided on the outer wall of the collar. A return spring is fixedly connected between the left side of the collar and the inner wall of the connecting flange.

[0007] Preferably, a pull rod is fixedly connected to the right side of the collar.

[0008] Preferably, the inclined surfaces are provided in three sets at equal intervals along the outer circumference of the collar, and the protrusions are provided in three sets at equal intervals along the outer circumference of the connecting flange. The inner walls of the three sets of protrusions are provided with positioning shafts, and the three sets of positioning shafts correspond one-to-one with the three sets of inclined surfaces.

[0009] Preferably, the groove has an open structure on both the side near the connecting flange and the right end, and the protrusion can be inserted into the groove from the opening at the right end of the groove.

[0010] Preferably, one end of the positioning shaft passes through the connecting flange and fits against the outer wall of the collar, and the other end of the positioning shaft passes through the protrusion and is inserted into the inner wall of the locking hole. The positioning shaft is slidably connected to the connecting flange and the protrusion at the through-hole.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention, through the design of the disassembly and assembly mechanism, allows for quick disassembly and assembly of the grinding wheel and the connecting flange. This enables the grinding wheel to be replaced separately when it is severely worn, thus allowing the connecting flange to be reused. Furthermore, the replacement process does not require disassembling the connecting flange, which not only reduces usage costs but also improves maintenance convenience. The groove with an opening on the right end ensures that the bushing can only mate with the connecting flange from the left side, allowing the protrusion to be inserted into the groove. This prevents the grinding wheel from being installed backwards, thus achieving a foolproof effect. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3 The metal material processing and grinding mechanism shown includes a connecting flange 1, a bushing 2, and a disassembly and assembly mechanism 3 connected to the output end of a grinding wheel. A protrusion 4 is fixedly connected to the outer wall of the connecting flange 1. The connecting flange 1 is rigidly connected to the power output end of the grinding wheel by bolts and nuts. The grinding wheel drives the connecting flange 1 to rotate at high speed. A grinding wheel 5 is fixedly connected to the outer wall of the bushing 2. The inner wall of the bushing 2 has a groove 6 that matches the protrusion 4. By cooperating with the protrusion 4 on the outer wall of the connecting flange 1 and the groove 6 on the inner wall of the bushing 2, the connecting flange 1 can drive the bushing 2 to rotate synchronously. At this time, the grinding wheel 5 on the outer wall of the bushing 2 can be used to grind the metal material. like Figure 2 - Figure 4 As shown, the disassembly and assembly mechanism 3 includes a push plate 31, which is slidably connected to the inner wall of the protrusion 4. A positioning shaft 32 is fixedly connected through and to the inner wall of the push plate 31. A retaining hole 33 is provided on the inner wall of the groove 6 for the positioning shaft 32 to be inserted. The positioning shaft 32, in conjunction with the retaining hole 33, can axially limit the connection between the connecting flange 1 and the bushing 2. A limit spring 34 is fixedly connected to the side wall of the push plate 31. The elasticity of the limit spring 34 can push the push plate 31, causing it to slide and reset on the inner wall of the protrusion 4. The inner wall of the connecting flange 1 is slidably connected to the groove 6. There is a collar 35, and the outer wall of the collar 35 has a bevel 36. By opening the bevel 36, the collar 35 can press the shaft end of the positioning shaft 32 while sliding. A return spring 37 is fixedly connected between the left side of the collar 35 and the inner wall of the connecting flange 1. Under the influence of no external force, the elasticity of the return spring 37 can axially limit the collar 35. A pull rod 38 is fixedly connected to the right side of the collar 35. The collar 35 can be pulled or pushed by the pull rod 38, so that the collar 35 slides on the inner wall of the connecting flange 1.

[0017] like Figure 2As shown, the inclined surface 36 is provided with three sets of equidistant openings along the outer wall of the collar 35, and the protrusion 4 is provided with three sets of equidistant openings along the outer wall of the connecting flange 1. The inner wall of each of the three sets of protrusions 4 is provided with a positioning shaft 32. The three sets of positioning shafts 32 correspond one-to-one with the three sets of inclined surfaces 36. When the collar 35 slides and the inclined surface 36 presses against the positioning shaft 32, the positioning shaft 32 pushes the push plate 31 to slide on the inner wall of the protrusion 4. At this time, the three sets of positioning shafts 32 will move synchronously.

[0018] like Figure 2 As shown, the groove 6 has an open structure on the side and right end near the connecting flange 1. The protrusion 4 can be inserted into the groove 6 from the opening at the right end of the groove 6. The bushing 2 and the connecting flange 1 can rotate synchronously by the cooperation of the protrusion 4 and the groove 6. The protrusion 4 can be inserted into the groove 6 from the opening at the right end of the groove 6 or pulled out from the groove 6.

[0019] like Figure 4 As shown, one end of the positioning shaft 32 passes through the connecting flange 1 and fits against the outer wall of the collar 35. The collar 35 can axially limit the positioning shaft 32, so that the positioning shaft 32 can be stably inserted into the inside of the retaining hole 33. The other end of the positioning shaft 32 passes through the protrusion 4 and is inserted into the inner wall of the retaining hole 33. The positioning shaft 32 is slidably connected to the connecting flange 1 and the protrusion 4 at the through-hole. When the positioning shaft 32 gradually protrudes out of the protrusion 4 and is inserted into the inside of the retaining hole 33, the protrusion 4 can be limited inside the groove 6 by the positioning shaft 32 cooperating with the retaining hole 33.

[0020] The working principle of this utility model is as follows: The connecting flange 1 is rigidly connected to the power output end of the grinding wheel by bolts and nuts. The grinding wheel drives the connecting flange 1 to rotate at high speed. At the same time, the protrusion 4 on the outer wall of the connecting flange 1 and the groove 6 on the inner wall of the bushing 2 can make the connecting flange 1 drive the bushing 2 to rotate synchronously. At this time, the grinding wheel 5 on the outer wall of the bushing 2 can be used to grind the metal material.

[0021] When the grinding wheel 5 is severely worn and needs replacement, first pull the collar 35 outward via the pull rod 38. This causes the collar 35 to slide on the inner wall of the connecting flange 1 and stretch the return spring 37. As the collar 35 slides, it causes the inclined surface 36 to gradually approach the positioning shaft 32. When the outer wall of the collar 35 is completely misaligned with the shaft end of the positioning shaft 32, the compressed limit spring 34 pushes the push plate 31, causing it to slide on the inner wall of the protrusion 4. At this time, the push plate 31 will drive the positioning shaft 32 to move synchronously, thus allowing one end of the positioning shaft 32 to be aligned with the inclined surface 36. 6. The other end is pulled out from the inside of the locking hole 33. When the positioning shaft 32 moves out from the inside of the locking hole 33, the limitation on the bushing 2 can be released. At this time, pull the grinding wheel 5 to make it slide the bushing 2 on the outer wall of the connecting flange 1. At the same time, the protrusion 4 will gradually move out of the groove 6 from the opening at the right end of the groove 6. When the bushing 2 is completely pulled out from the outer wall of the connecting flange 1, the disassembly of the grinding wheel 5 can be completed. The grinding wheel 5 can be replaced directly. At this time, the connecting flange 1 is still fixed at the power output end of the grinding machine, so there is no need to disassemble the connecting flange 1.

[0022] When the replaced connecting flange 1 needs to be installed, first pull the collar 35 outward by the pull rod 38, so that the collar 35 slides on the inner wall of the connecting flange 1 and stretches the return spring 37, so that the outer wall of the collar 35 is misaligned with the shaft end of the positioning shaft 32, so that the compressed limit spring 34 can push the push plate 31, so that the push plate 31 drives the positioning shaft 32 to slide into the inside of the protrusion 4 and fit against the outer wall of the inclined surface 36, so that the positioning shaft 32 no longer protrudes from the protrusion 4. Then, the bushing 2 on the inner wall of the replaced grinding wheel 5 is placed on the outer wall of the connecting flange 1, aligning the groove 6 with the protrusion 4. The grinding wheel 5 is then pushed to cause the bushing 2 to slide on the outer wall of the connecting flange 1, allowing the protrusion 4 to gradually insert into the groove 6 from the right end opening. Once the protrusion 4 is fully inserted into the groove 6, the collar 35 can be pushed by the pull rod 38, causing the collar 35 to slide into the connecting flange 1. At the same time, the collar 35 will cause the inclined surface 36 to press against the end of the positioning shaft 32, causing the positioning shaft 32 to push the push plate 31 to slide on the inner wall of the protrusion 4. At this time, the push plate 31 will gradually limit the spring 34, and the positioning shaft 32 will gradually protrude from the protrusion 4 and insert into the inside of the retaining hole 33, until the end of the positioning shaft 32 is aligned with the inclined surface 36. The sleeve 2 is then placed against the outer wall of the collar 35. At this point, without the influence of external force, the elasticity of the return spring 37 can axially limit the collar 35. The collar 35 can axially limit the positioning shaft 32, thus allowing the positioning shaft 32 to be stably inserted into the inside of the retaining hole 33. At this point, the positioning shaft 32, in conjunction with the retaining hole 33, can limit the protrusion 4 inside the groove 6. The cooperation between the protrusion 4 and the groove 6 allows the bushing 2 and the connecting flange 1 to rotate synchronously. Simultaneously, under the limiting action of the positioning shaft 32, the bushing 2 and the connecting flange 1 can be axially limited, thus maintaining the connection between the bushing 2 and the connecting flange 1. This completes the replacement of the grinding wheel 5 without disassembling the connecting flange 1, allowing the connecting flange 1 to be reused.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
