Description

Technical Field

[0001] This invention relates to the field of grinding equipment for ring-shaped workpieces, and more particularly to an automatic grinding device for ring-shaped workpieces. Background Technology

[0002] A grinding device is a piece of equipment used to process the surface of materials. It is designed to improve the surface quality of objects through friction or grinding. Grinding devices are widely used in various industrial fields and can be used to process various materials such as metal, wood, plastic, and glass to improve the smoothness, dimensional accuracy and surface quality of products. A ring workpiece grinding device is a device that can grind the outer surface of a ring-shaped workpiece.

[0003] Grinding ring-shaped workpieces is a crucial step in ring machining, as the surface quality directly impacts the product's value. For certain materials, the direction of the grinding grain is critical. For example, when grinding wood, the grain must align with the wood grain; otherwise, it will leave intersecting lines and a rough surface, affecting aesthetics and feel, as seen in gymnastic wooden rings. When grinding metal rings, grinding along the outer circumference creates a more robust and sophisticated look. Detailed grinding often requires changing abrasive grains of different grits, but traditional grinding relies on manual abrasive changes, which is inefficient. Especially when a workpiece requires a combination of surface finishes, this can only be achieved through repetitive and tedious manual operations, and uneven grinding pressure can negatively affect the final quality.

[0004] Therefore, it is necessary to design an automatic grinding device for ring-shaped workpieces, which can automatically grind the outer surface of the ring-shaped workpieces, thereby improving grinding efficiency and quality. Summary of the Invention

[0005] To address the problems in the prior art, this application proposes an automatic grinding device for ring-shaped workpieces, which can automatically grind the outer surface of ring-shaped workpieces, thereby improving grinding efficiency and quality.

[0006] This invention provides an automatic grinding device for ring-shaped workpieces. The automatic grinding device for ring-shaped workpieces includes a main frame, within which a grinding mechanism and a clamping mechanism are installed. The grinding mechanism includes a grinding drive assembly and two sets of grinding assemblies. The grinding drive assembly is used to drive the two sets of grinding assemblies to move closer or further apart to grind or release the ring-shaped workpiece. The clamping mechanism includes a support frame mounted on the main frame. A clamping rotation drive component is mounted on the support frame, and a clamping frame is rotatably mounted about the vertical direction. A clamping rotation assembly is mounted on the clamping frame. The clamping rotation assembly is used to clamp the ring-shaped workpiece and drive the ring-shaped workpiece to rotate about the horizontal direction. When the grinding drive assembly drives the two sets of grinding assemblies to move closer together to grind the ring-shaped workpiece, the clamping rotation drive component can drive the clamping frame to rotate so that the ring-shaped workpiece rotates about the center of the generatrix of the grinding area.

[0007] As a further improvement to the above technical solution:

[0008] The aforementioned automatic grinding device for ring-shaped workpieces further includes a clamping and rotating assembly comprising a first clamping frame and a second clamping frame, which are respectively mounted on the upper and lower sides of the clamping frame.

[0009] The aforementioned automatic grinding device for ring-shaped workpieces further includes a support rod spanning between two first clamping brackets on the same side or two second clamping brackets on the same side. A first auxiliary wheel assembly and a second auxiliary wheel assembly are mounted on the support rod. The auxiliary wheel of the first auxiliary wheel assembly can roll against the outer wall of the clamped ring-shaped workpiece, and the auxiliary wheel of the second auxiliary wheel assembly can roll against the inner wall of the clamped ring-shaped workpiece.

[0010] The aforementioned automatic grinding device for ring-shaped workpieces further includes an auxiliary wheel assembly comprising a mounting frame mounted on a support rod. A mounting seat is slidably mounted on the support rod, and an auxiliary wheel is rotatably mounted on the mounting seat via a telescopic shaft in a horizontal direction. A lead screw motor is mounted on the support rod, which drives the mounting seat to slide relative to the support rod and, in conjunction with the telescopic shaft, adjusts the position of the clamped ring-shaped workpiece. An arc groove is formed on the outer wall of the auxiliary wheel.

[0011] In the aforementioned automatic grinding device for ring-shaped workpieces, a guide spring is further installed on the support rod, a guide slide plate is installed on the clamping bracket of the second clamping frame, and an outlet groove is installed on the main frame. When the telescopic drive drives the first clamping bracket and the second clamping bracket to rotate relative to each other so that the clamping grooves of the two drive clamping wheels or the two clamping wheels cooperate with each other to release the ring-shaped workpiece, the guide spring guides the ring-shaped workpiece to the guide slide plate, and the ring-shaped workpiece slides along the guide slide plate into the outlet groove and slides out.

[0012] The aforementioned automatic grinding device for ring-shaped workpieces further includes a grinding mechanism comprising a mounting base, a grinding drive assembly comprising a drive screw and a grinding rotation drive component, wherein the drive screw is rotatably mounted on the mounting base in a horizontal direction, the grinding rotation drive component is mounted on the mounting base, both grinding assemblies are slidably mounted on the mounting base and threadedly engaged with the drive screw, and the grinding rotation drive component can drive the drive screw to rotate, thereby causing the two grinding assemblies to move closer or further apart.

[0013] The aforementioned automatic grinding device for ring-shaped workpieces further includes a grinding assembly comprising a sliding seat and a grinding component. The sliding seat is slidably mounted on the mounting base and threadedly engaged with the drive screw. The grinding component is detachably mounted on the sliding seat.

[0014] In the aforementioned automatic grinding device for ring-shaped workpieces, a horizontal guide rod is installed on the main frame, a guide block is installed on the support frame, the guide block is slidably installed on the horizontal guide rod, a sliding rotation drive is also installed on the main frame, rollers are rotatably installed on opposite sides of the main frame, two rollers are rotatably connected by a conveyor belt, a clamping seat is installed on the support frame, the clamping seat is clamped and fixed on the conveyor belt, and the sliding rotation drive can drive one of the rollers to rotate, so that the conveyor belt drives the support frame to slide along the horizontal guide rod to approach or move away from the grinding mechanism.

[0015] Furthermore, in the aforementioned automatic grinding device for ring-shaped workpieces, the main frame is also equipped with an inlet slide groove, through which the ring-shaped workpiece can be fed to the clamping mechanism.

[0016] In the aforementioned automatic grinding device for ring-shaped workpieces, the main frame is further provided with a dust collection liner, which is connected to a dust suction pipe.

[0017] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0018] The automatic grinding device for ring-shaped workpieces provided by this invention has at least the following advantages compared with the prior art: When grinding a ring-shaped workpiece, the workpiece to be ground is first clamped on a clamping rotating assembly. The clamping rotating assembly clamps the workpiece and drives it to rotate horizontally. Then, a grinding drive assembly drives two sets of grinding components to move closer together to grind the workpiece. During grinding, the clamping rotating drive component drives the clamping frame to rotate, causing the workpiece to rotate around the center of the generatrix of the grinding area. This allows the grinding components to perform comprehensive grinding of the circumference of the generatrix of the workpiece. Furthermore, because the clamping rotating assembly can drive the workpiece to rotate horizontally, the grinding components can perform comprehensive grinding of the circumference of the workpiece. This automatic grinding device for ring-shaped workpieces can automatically grind the outer surface of the workpiece, improving grinding efficiency. Moreover, because the contact pressure between the grinding components and the outer surface of the workpiece is fixed, the grinding quality is improved.

[0036] This invention provides an automatic grinding device for ring-shaped workpieces, which can automatically grind the outer surface of ring-shaped workpieces, improving grinding efficiency and quality.

[0037] Please see Figure 1 and Figure 2The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention includes a main frame 110, within which a grinding mechanism 120 and a clamping mechanism 130 are installed. The grinding mechanism 120 includes a grinding drive assembly 121 and two sets of grinding assemblies 122. The grinding drive assembly 121 drives the two sets of grinding assemblies 122 to move closer or further apart to grind or release the ring-shaped workpiece. The clamping mechanism 130 includes components mounted on the main frame 110. The support frame 131 is equipped with a clamping rotary drive 132 and a clamping frame 133 that is rotatably mounted around the vertical direction. The clamping frame 133 is equipped with a clamping rotary assembly, which is used to clamp the ring-shaped workpiece and drive the ring-shaped workpiece to rotate around the horizontal direction. When the grinding drive assembly 121 drives the two sets of grinding assemblies 122 to approach each other to grind the ring-shaped workpiece, the clamping rotary drive 132 can drive the clamping frame 133 to rotate so that the ring-shaped workpiece rotates around the center of the maternal circle of the grinding area.

[0038] When grinding a ring-shaped workpiece, the workpiece is first clamped on the clamping and rotating assembly. The clamping and rotating assembly clamps the workpiece and drives it to rotate around the horizontal direction. Then, the grinding drive assembly 121 drives two sets of grinding assemblies 122 to move closer to each other to grind the workpiece. During grinding, the clamping and rotating drive 132 drives the clamping frame 133 to rotate so that the workpiece rotates around the center of the maternal circle of the grinding area. This allows the grinding assembly 122 to perform comprehensive grinding on the circumference of the maternal circle of the workpiece. Since the clamping and rotating assembly can drive the workpiece to rotate around the horizontal direction, the grinding assembly 122 can perform comprehensive grinding on the circumference of the workpiece.

[0039] The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention can automatically grind the outer surface of the ring-shaped workpiece, thereby improving grinding efficiency. Furthermore, since the contact pressure between the grinding component 122 and the outer surface of the ring-shaped workpiece is fixed, the grinding quality is improved.

[0040] The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention, for details please refer to... Figure 3The clamping and rotating assembly includes a first clamping frame and a second clamping frame, which are respectively mounted on the upper and lower sides of the clamping frame 133. Each clamping frame includes a first clamping bracket 134 and a second clamping bracket 135. Both the first clamping bracket 134 and the second clamping bracket 135 are hinged to the clamping frame 133 in a vertical direction, and are meshed by a sector gear 136. A telescopic drive is installed between the first clamping bracket 134 and the second clamping bracket 135. The first clamping frame is equipped with a rotating drive 138 on its clamping bracket. The output shaft of the rotating drive 138 is equipped with a drive clamping wheel 139. The outer side wall of the drive clamping wheel 139 is provided with a clamping groove 140. The clamping bracket of the second clamping frame is rotatably equipped with a clamping wheel 141. The telescopic drive 137 can drive the first clamping bracket 134 and the second clamping bracket 135 to rotate relative to each other and move closer so that the clamping grooves 140 of the two drive clamping wheels 139 or the two clamping wheels 141 cooperate with each other to clamp the ring workpiece.

[0041] When the clamping and rotating assembly needs to clamp the ring-shaped workpiece, the telescopic drive 137 first drives the first clamping bracket 134 and the second clamping bracket 135 to rotate away from each other. Then, the ring-shaped workpiece to be ground is placed between the clamping grooves 140 of the two drive clamping wheels 139 and the two clamping wheels 141. Finally, the telescopic drive 137 drives the first clamping bracket 134 and the second clamping bracket 135 to rotate closer to each other so that the clamping grooves 140 of the two drive clamping wheels 139 or the two clamping wheels 141 cooperate with each other to clamp the ring-shaped workpiece. The rotation drive 138 drives the drive clamping wheels 139 to rotate so that the ring-shaped workpiece rotates around the horizontal direction.

[0042] The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention further includes a support rod 142 spanning between two first clamping brackets 134 or two second clamping brackets 135 on the same side. A first auxiliary wheel assembly 143 and a second auxiliary wheel assembly 144 are mounted on the support rod 142. The auxiliary wheel 147 of the first auxiliary wheel assembly 143 can roll against the outer wall of the clamped ring-shaped workpiece, and the auxiliary wheel 147 of the second auxiliary wheel assembly 144 can roll against the inner wall of the clamped ring-shaped workpiece.

[0043] When the clamping and rotating assembly clamps the ring-shaped workpiece, the auxiliary wheel 147 of the first auxiliary wheel assembly 143 rolls against the outer side wall of the clamped ring-shaped workpiece, and the auxiliary wheel 147 of the second auxiliary wheel assembly 144 rolls against the inner side wall of the clamped ring-shaped workpiece, thereby positioning the clamped ring-shaped workpiece and preventing displacement of the clamped ring-shaped workpiece during grinding, thereby improving the grinding quality.

[0044] In this embodiment, please refer to Figure 3The auxiliary wheel 147 assembly includes a mounting bracket 144, which is mounted on a support rod 142. A mounting seat 145 is slidably mounted on the support rod 142. The auxiliary wheel 147 is rotatably mounted on the mounting seat 145 via a telescopic shaft 146. A lead screw motor 148 is mounted on the support rod 142. The lead screw motor 148 drives the mounting seat 145 to slide relative to the support rod 142 and, in conjunction with the telescopic shaft 146, adjusts the position of the clamped ring-shaped workpiece. The outer side wall of the auxiliary wheel 147 has an arc groove. An inlet slide 116 is also mounted on the main frame 110, through which the ring-shaped workpiece can be loaded into the clamping mechanism 130.

[0045] During loading, the ring-shaped workpiece is loaded through the inlet slide 116 to the position between the clamping slots 140 of the two drive clamping wheels 139. The telescopic drive 137 drives the first clamping bracket 134 and the second clamping bracket 135 to rotate relative to each other so that the clamping slots 140 of the two drive clamping wheels 139 and the two clamping wheels 141 cooperate to clamp the ring-shaped workpiece. The auxiliary wheel 147 of the first auxiliary wheel assembly 143 rolls against the outer side wall of the clamped ring-shaped workpiece, and the auxiliary wheel 147 of the second auxiliary wheel assembly 144 rolls against the inner side wall of the clamped ring-shaped workpiece. The rotation drive 138 drives the drive clamping wheel 139 to rotate so that the ring-shaped workpiece rotates around the horizontal direction.

[0046] When the ring-shaped workpiece contacts the two drive clamping wheels 139, the friction generated by the pressure applied to the ring-shaped workpiece and the torque generated by the rotation of the drive clamping wheels 139 cause the ring-shaped workpiece to rotate. At the same time, the ring-shaped workpiece is wound up and moved forward. Finally, it is restricted by the auxiliary wheel 147 of the lower second auxiliary wheel assembly 144 and stops moving forward. As the two drive clamping wheels 139 move closer to the ring-shaped workpiece, the lower edge of the clamping groove 140 of the two drive clamping wheels 139 contacts the ring-shaped workpiece under pressure. As the pressure increases, the ring-shaped workpiece rotates and moves towards the middle of the clamping groove 140. Since the clamping groove 140 is on top, the ring-shaped workpiece moves upward. Finally, it is restricted by the auxiliary wheel 147 of the first auxiliary wheel assembly 143 and stops moving upward. The screw motor 148 and the telescopic shaft 146 are controlled to align the center of the grinding part of the ring-shaped workpiece with the rotation center line of the clamping frame 133.

[0047] The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention, further refer to... Figure 1 , Figure 2 as well as Figure 3The support rod 142 is also equipped with a guide spring 149, and the clamping brackets of the second clamping frame are all equipped with guide slide plates 152. The main frame 110 is also equipped with an outlet slide groove 111. When the telescopic drive 137 drives the first clamping bracket 134 and the second clamping bracket 135 to rotate away from each other so that the clamping grooves 140 of the two drive clamping wheels 139 or the two clamping wheels 141 cooperate with each other to release the ring workpiece, the guide spring 149 guides the ring workpiece to the guide slide plate 152, and the ring workpiece slides along the guide slide plate 152 to slide out into the outlet slide groove 111.

[0048] After grinding, the telescopic drive component 137 drives the first clamping bracket 134 and the second clamping bracket 135 to rotate away from each other so that the clamping grooves 140 of the two drive clamping wheels 139 and the two clamping wheels 141 cooperate to release the ring workpiece. The ring workpiece begins to fall due to the loss of support and gravity. It hits the guide spring 149 and slides to one side along the guide spring 149, eventually falling onto the guide slide plate 152. At this time, the gravitational potential energy of the ring workpiece is converted into kinetic potential energy. The ring workpiece rolls into the outlet slide groove 111 along the guide slide plate 152 and slides out.

[0049] In this embodiment, please refer to Figure 1 and Figure 2 The grinding mechanism 120 includes a mounting base 123. The grinding drive assembly 121 includes a drive screw and a grinding rotation drive component. The drive screw is rotatably mounted on the mounting base 123 in a horizontal direction. The grinding rotation drive component is also mounted on the mounting base 123. Both grinding assemblies 122 are slidably mounted on the mounting base 123 and threadedly engaged with the drive screw. The grinding rotation drive component can drive the drive screw to rotate, causing the two grinding assemblies 122 to move closer or further apart. A drive motor is used for the grinding rotation drive component. Each grinding assembly 122 includes a sliding seat 124 and a grinding element 125. The sliding seat 124 is slidably mounted on the mounting base 123 and threadedly engaged with the drive screw. The grinding element 125 is detachably mounted on the sliding seat 124. (Please refer to...) Figure 5 This structure allows for the replacement of different grinding parts 125 to create different textures on the ring-shaped workpiece, while also improving grinding efficiency.

[0050] The automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention, for details please refer to [link / reference]. Figure 1 and Figure 2A horizontal guide rod 112 is installed on the main frame 110, and a guide block 150 is installed on the support frame 131. The guide block 150 is slidably installed on the horizontal guide rod 112. A sliding rotation drive 113 is also installed on the main frame 110. Rollers 114 are rotatably installed on opposite sides of the main frame 110. The two rollers 114 are rotatably connected by a conveyor belt 115. A clamping seat 151 is installed on the support frame 131. The clamping seat 151 is clamped and fixed on the conveyor belt 115. The sliding rotation drive 113 can drive one of the rollers 114 to rotate, so that the conveyor belt 115 drives the support frame 131 to slide along the horizontal guide rod 112 to approach or move away from the grinding mechanism 120.

[0051] When loading or unloading is required, the sliding rotary drive 113 drives one of the rollers 114 to rotate, so that the conveyor belt 115 drives the support frame 131 to slide along the horizontal guide rod 112 away from the grinding mechanism 120 and closer to the outlet chute 111 or the inlet chute 116; when grinding is required, the sliding rotary drive 113 drives one of the rollers 114 to rotate, so that the conveyor belt 115 drives the support frame 131 to slide along the horizontal guide rod 112 and closer to the grinding mechanism 120.

[0052] Abrasives come in different grades based on grit size: for example, 80 grit, 120 grit, 240 grit, etc. The higher the grit number, the finer the abrasive particles, and different grit numbers produce different textures. If you want to turn a rough surface into a shiny one, you generally can't directly use a high-grit abrasive. This is because the higher the grit number, the finer the particles, the lower the grinding efficiency, and the waste generated during grinding easily clogs the gaps between the abrasive particles, further reducing grinding efficiency. Therefore, the conventional practice is to first grind with a low-grit abrasive, then with a slightly higher grit, and then with another slightly higher grit until the desired shine is achieved. This is why different grit numbers are frequently used during the grinding process.

[0053] Please see Figure 1 and Figure 2The grinding component 125 includes multiple wheel-type abrasives arranged side by side. In this embodiment, the three wheel-type abrasives are 80 grit, 120 grit, and 600 grit abrasives, respectively. When the grinding operation begins, one of the rollers 114 is driven to rotate by the sliding rotation drive component 113, so that the conveyor belt 115 drives the support frame 131 to slide along the horizontal guide rod 112, so that the ring-shaped workpiece held by the clamping rotation assembly enters the 80 grit abrasive for grinding. After the grinding operation with the 80 grit abrasive is completed, the sliding rotation drive component 113 drives the ring-shaped workpiece held by the clamping rotation assembly to enter the 120 grit abrasive for grinding. After the grinding operation with the 120 grit abrasive is completed, the sliding rotation drive component 113 drives the ring-shaped workpiece held by the clamping rotation assembly to enter the 600 grit abrasive for grinding. This operation allows for quick replacement of abrasives with different roughness. Compared to the traditional process of switching between different grit sizes of abrasives, the automatic grinding device 100 for ring-shaped workpieces provided in this embodiment of the invention can improve the efficiency of switching between different grit sizes of abrasives.

The dust from the grinding operation is trapped inside the dust collection liner 117 and discharged to the external recycling device through the dust suction pipe 118. The main frame 110 is also covered with an organic shell.
