Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a bevel edge sweeping machine. Background Art

[0002] The application of sapphire in consumer electronics has opened up new market space for the sapphire industry in addition to LED applications. In the future, the application of sapphire in consumer electronics will gradually extend from "small screens" to "large screens", that is, from the current smaller areas such as cameras and Home buttons to larger areas such as watch dials and even mobile phone screens. With the increase in the application of sapphire in consumer electronics, the sapphire industry will still have growth momentum and room for growth in the future. Since sapphire is a single crystal of aluminum oxide, the crystal hardness is very high, with a Mohs hardness of 9, second only to the hardest diamond. Screens, lenses or buttons made of sapphire need to be beveled and polished on the edges. In the existing bevel edge polishing machine, the workpiece is clamped by a fixture and pressed against the grinding wheel, and the grinding wheel rotates to grind the workpiece. Since the position of the workpiece remains fixed during the grinding process, the position on the grinding wheel is repeatedly polished, causing excessive wear of the grinding wheel in part, resulting in the grinding wheel being unable to reliably grind the workpiece and being scrapped, causing the grinding wheel to be consumed too quickly, increasing production costs; the bevel edge polishing machine adsorbs the product on the fixture through its vacuum device, but the fixtures of the products are all special and need to be engraved separately, with a long engraving cycle. The fixture will wear during the grinding process and needs to be replaced as a whole after wear, which is costly and not conducive to production needs. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems in the prior art and propose a bevel edge sweeping machine. The technical problem to be solved by the present invention is: how to reduce the cost of the bevel edge sweeping process.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A bevel edge sweeper comprises a base, on which a grinding disc is rotatably arranged, and is characterized in that a left-right moving mechanism is also provided on the base, a front-and-back moving mechanism which can be driven by the left-and-right moving mechanism to move left-and-right, a lifting mechanism which can be driven by the front-and-back moving mechanism to move back-and-forth, a cross bar which can be driven by the lifting mechanism to move up and down is rotatably connected to the lifting mechanism, a vacuum tube connected to a vacuum system is provided on the cross bar, the vacuum tube is arranged along the moving direction of the front-and-back moving mechanism, a motor which can drive the vacuum tube to rotate is also provided on the cross bar, and a swing mechanism which drives the vacuum tube to swing up and down relative to the grinding disc is also provided on the lifting mechanism.

[0006] The vacuum system is used to form negative pressure at the end of the vacuum tube to adsorb the workpiece to be polished, and the swing mechanism drives the crossbar to rotate, and the crossbar drives the vacuum tube to swing up and down, so that the workpiece to be polished contacts the grinding disc, and the grinding disc rotates to polish the workpiece. The existing workpiece grinding is to press the workpiece against the grinding disc and then rotate the workpiece. However, after the workpiece is pressed against the grinding disc, its position remains fixed, resulting in repeated polishing of the same position on the grinding disc with the workpiece, causing severe wear of the local position of the grinding disc and making it unable to continue production and needing to be replaced. In this case, the left and right moving mechanism drives the front and back moving mechanism to move left and right, and the front and back moving mechanism lifting mechanism, the vacuum tube and the workpiece move back and forth during the grinding process. Therefore, during the grinding process, the front and back moving mechanism and the left and right moving mechanism drive the workpiece to contact and polish different positions on the grinding disc, thereby avoiding excessive grinding of the local part of the grinding disc The wear on the grinding disc is uniform, which can extend the service life of the grinding disc, thereby reducing the frequency of changing the grinding disc in the bevel polishing process, and thus reducing the production cost of the process; the lifting mechanism and the swing mechanism adjust the specification parameters of the bevel of the grinded workpiece. The existing workpiece grinding is carried out by rotating the workpiece and the grinding disc, and the grinding disc acts on the workpiece in only two grinding and cutting directions. In this case, the vacuum tube drives the workpiece to rotate and forms a grinding and cutting direction one with the grinding disc, the grinding disc rotates and forms a grinding and cutting direction two with the workpiece, the left and right moving mechanism drives the workpiece to move left and right and forms a grinding and cutting direction three with the grinding disc, and the front and back moving mechanism drives the workpiece to move back and forth and forms a grinding and cutting direction four with the grinding disc. Through the front and back moving mechanism, the left and right moving mechanism, the rotation of the vacuum tube and the rotation of the grinding disc, four grinding and cutting directions are formed on the workpiece, thereby improving the grinding quality and efficiency of the workpiece.

[0007] In the above-mentioned bevel edge polishing machine, the swing mechanism includes a linear drive device arranged on the lifting mechanism, a swing rod is arranged between the linear drive device and the cross bar, one end of the swing rod is fixedly connected to the cross bar, and the other end is rotatably connected to the output end of the linear drive device. The output end of the linear drive device acts on the swing rod, the swing rod drives the cross bar to rotate, the cross bar rotates, drives the vacuum tube to swing upward or downward, the workpiece adsorbed by the vacuum tube moves downward and abuts against the grinding disc, and the grinding disc rotates to grind the bevel edge on the workpiece.

[0008] In the above-mentioned bevel edge polishing machine, the output shaft of the motor 1 is provided with a gear 1, and the vacuum tube is provided with a gear 2 meshing with the gear 1. The output shaft of the motor 1 rotates to drive the gear 1 and the gear 2 to rotate, and the gear 2 drives the vacuum tube to rotate, so that the workpiece rotates relative to the grinding disc, and the workpiece and the grinding disc form a grinding cutting direction. The grinding disc also rotates relative to the workpiece, and the grinding disc forms a second grinding cutting direction relative to the workpiece. The vacuum tube and the grinding disc rotate simultaneously, and the workpiece forms two grinding cutting directions on the grinding disc, thereby improving the grinding quality and efficiency of the workpiece.

[0009] In the above-mentioned bevel edge sweeper, the left-right moving mechanism includes a horizontally placed guide rail 1, a screw 1, a mounting platform 1 and a motor 2 for driving the screw 1 to rotate, the mounting platform 1 is provided with a slide groove 1 that cooperates with the guide rail 1, and the mounting platform 1 is screwed to the screw 1, the front-back moving mechanism includes a guide rail 2, a screw 2, a mounting platform 2 and a motor 3 that drives the screw 2 to rotate, the mounting platform 2 is provided with a slide groove 2 that cooperates with the guide rail 2, and the mounting platform 2 is screwed to the screw 2, the lifting mechanism includes a guide rail 3, a screw 3, a mounting platform 3 and a motor 4 that drives the screw 3 to rotate, the guide rail 3 and the screw 3 are both vertically arranged on the mounting platform 2, the mounting platform 3 is provided with a slide groove 3 that cooperates with the guide rail 3, and the mounting platform 3 is screwed to the screw 3. Motor 2 drives screw 1 to rotate, so that mounting platform 1 moves left and right along guide rail 1, and mounting platform 1 drives mounting platform 2, guide rail 2, screw 2 and other components to move left and right; motor 3 drives screw 2 to rotate, so that mounting platform 2 moves forward and backward along guide rail 2, and mounting platform 2 drives mounting platform 3, guide rail 3, screw 3 and other components to move forward and backward; motor 4 drives screw 3 to rotate, so that mounting platform 3 moves up and down along guide rail 3, and mounting platform 3 drives crossbars and other components to move up and down.

[0010] In the above-mentioned bevel edge polishing machine, two grinding discs are rotatably arranged on the base, and the abrasive grains on one grinding disc are smaller than the abrasive grains on the other grinding disc. The bevel edge polishing machine has two grinding discs with different abrasive grain sizes, and cooperates with the left and right moving mechanism so that the bevel edge polishing machine can realize the functions of rough grinding and fine grinding.

[0011] In the above-mentioned bevel edge polishing machine, the front end of the vacuum tube is connected to a fixture, the fixture includes a base connected to the vacuum tube, the front end of the base is detachably connected to a connecting seat, the base is provided with a first vent hole penetrating the front end face and the rear end face of the base, the first vent hole is communicated with the vacuum tube, the connecting seat is provided with a second vent hole penetrating the front end face and the rear end face of the connecting seat, the first vent hole is communicated with the second vent hole, and the front end face of the connecting seat is inwardly concave and provided with a positioning groove that cooperates with the workpiece to be polished. The fixture is installed on the vacuum tube, and the connecting seat and the base are detachably connected. The workpiece to be polished is placed at the front end of the connecting seat and matched with the positioning groove. The vacuum tube connects the vent hole 1 and the vent hole 2. The vacuum system generates negative pressure at the end of the vent hole 2 to adsorb the workpiece, and the positioning groove can prevent the workpiece from shifting during the polishing process. When the product is replaced and the original fixture cannot adapt to the new workpiece, the connecting seat can be removed from the base and replaced, and there is no need to disassemble the entire fixture, so that the fixture can adapt to different workpieces. If the connecting seat is accidentally worn during the polishing process, resulting in a decrease in accuracy, it is only necessary to disassemble and replace the connecting seat. Since the size of the fixture installed on the bevel sweeper has certain requirements to ensure that the workpiece clamped by it can be polished by the grinding disc in a fixed position, if the fixture is integrated, it is necessary to disassemble and replace the integrated fixture. Since the connecting seat and the base of this fixture are detachably connected, when the product is replaced or the front end of the fixture is worn, the connecting seat can be replaced, so that the fixture can be easily replaced to adapt to different production needs and reduce replacement costs.

[0012] In the above-mentioned bevel edge sweeper, the base is provided with a threaded hole 1, the connecting seat is provided with a threaded hole 2 which is in communication with the threaded hole 1, and a bolt is provided between the base and the connecting seat, and the bolt is screwed with the threaded hole 1 and the threaded hole 2 respectively. The bolt is screwed with the threaded hole 1 and the threaded hole 2 respectively to connect the base and the connecting seat, and when the connecting seat needs to be disassembled, the bolt only needs to be taken out from the threaded hole 1 and the threaded hole 2 to realize the disassembly of the base and the connecting seat.

[0013] In the above-mentioned bevel edge sweeper, the front end of the connection seat is also provided with a countersunk hole that is in communication with the second threaded hole, the countersunk hole penetrates the front end face of the connection seat, and the head of the bolt is completely located in the countersunk hole. The countersunk hole is provided so that the head of the bolt does not protrude relative to the front end face, and when the workpiece is placed on the front end face of the connection seat, the workpiece can fit with the front end face of the connection seat, ensuring that the workpiece can be reliably adsorbed on the connection seat.

[0014] In the above-mentioned bevel edge polishing machine, the front end of the connecting seat is in the shape of a truncated cone with a smaller diameter at the front and a larger diameter at the back. During the grinding process of the workpiece, the connecting seat is tilted relative to the grinding disc, and the front end of the connecting seat is in the shape of a truncated cone with a smaller diameter at the front and a larger diameter at the back, which can reduce the possibility of collision between the connecting seat and the grinding disc and reduce the possibility of damage to the fixture.

[0015] In the above-mentioned bevel edge polishing machine, the positioning groove is circular. The workpiece is placed in the positioning groove to limit the workpiece and prevent the workpiece from deviating during the polishing process.

[0016] Compared with the existing technology, this bevel edge sweeper has the following advantages:

[0017] 1. When grinding the workpiece, four grinding and cutting directions can be formed on the workpiece at the same time, improving the grinding quality and efficiency of the workpiece.

[0018] 2. Through the forward and backward moving mechanism and the left and right moving mechanism, different positions on the grinding disc can contact and grind the workpiece, avoiding excessive local wear of the grinding disc, reducing the frequency of grinding disc replacement in the bevel polishing process, and thus reducing the production cost of the process.

[0019] 3. The fixture is detachably connected through the base and the connecting seat. When the product changes, the connecting seat can be replaced to adapt to different products, reducing the replacement cost.

[0020] 4. The connection seat is made of epoxy board, which has low cost and is easier to carve, thus reducing replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 2 3d drives the screw 1 3b to rotate, so that the mounting platform 1 3c moves left and right along the guide rail 1 3a, and the mounting platform 1 3c drives the mounting platform 2 4c, the guide rail 2 4a and the screw 2 4b to move left and right; the motor 3 4d drives the screw 2 4b to rotate, so that the mounting platform 2 4c moves forward and backward along the guide rail 2 4a, and the mounting platform 2 4c drives the mounting platform 3 5c, the guide rail 3 5a and the screw 3 5b to move forward and backward; the motor 4 5d drives the screw 3 5b to rotate, so that the mounting platform 3 5c moves up and down along the guide rail 3 5a, and the mounting platform 3 5c drives the crossbar 7 and other components to move up and down. The bevel edge polishing machine has two grinding discs 2 with different abrasive grain sizes, and cooperates with the left and right moving mechanism 3 to enable the bevel edge polishing machine to achieve the functions of rough grinding and fine grinding.

[0032] like Figures 1 to 3 As shown, a connecting bracket is provided on the mounting platform three 5c, and a cross bar 7 is rotatably connected to the connecting bracket. The lifting mechanism 5 is also provided with a swing mechanism 6 for driving the cross bar 7 to rotate, wherein the swing mechanism 6 includes a linear drive device 6a installed on the mounting platform three 5c, and a swing rod 6b is provided between the linear drive device 6a and the cross bar 7. One end of the swing rod 6b is fixedly connected to the cross bar 7, and the other end is rotatably connected to the output end of the linear drive device 6a. The linear drive device 6a can be a cylinder or a hydraulic cylinder. A cylinder is preferably used. Specifically, the piston rod end of the cylinder is rotatably connected to the swing rod 6b.

[0033] like Figure 2 and Figure 3As shown, a vacuum tube 8 is provided on the cross bar 7 to rotate along the moving direction of the front-rear moving mechanism 4, a bearing is provided between the vacuum tube 8 and the cross bar 7 to enable the vacuum tube 8 to rotate relative to the cross bar 7, a motor 10 is also provided on the cross bar 7, a gear 11 is provided on the output shaft of the motor 10, a gear 2 12 is sleeved on the vacuum tube 8, the gear 2 12 is meshed with the gear 11, and the vacuum tube 8 is driven to rotate by the operation of the motor 10.

[0034] like Figure 3 As shown, the tail end of the vacuum tube 8 is connected to the vacuum system, and the vacuum system includes a vacuum pump. The vacuum pump and the vacuum tube 8 are connected by a hose, and a connector is provided at the connection. The vacuum tube 8 is plugged into the connector, and the connector has structures such as bearings and sealing rings, so that the vacuum pump can form negative pressure at the front end of the vacuum tube 8 and enable the vacuum tube 8 to rotate smoothly.

[0035] like Figures 1 to 4 As shown, negative pressure is formed at the end of the vacuum tube 8 through the vacuum system to adsorb the workpiece to be polished, the swing mechanism 6 drives the cross bar 7 to rotate, and the cross bar 7 drives the vacuum tube 8 to swing up and down, so that the workpiece to be polished contacts the grinding disc 2, and the grinding disc 2 rotates to polish the workpiece, and the workpiece is driven to move forward, backward, left and right during the polishing process by the front and back moving mechanism 4 and the left and right moving mechanism 3, so that different positions on the grinding disc 2 can contact the workpiece for polishing, avoiding local excessive wear of the grinding disc 2. Since the wear on the grinding disc 2 is uniform, the service life of the grinding disc 2 can be extended, thereby reducing the replacement frequency of the grinding disc 2 in the bevel polishing process. , thereby reducing the production cost of this process; the lifting mechanism 5 and the swing mechanism 6 adjust the specification parameters of the bevel of the polished workpiece, the vacuum tube 8 drives the workpiece to rotate and forms a polishing cutting direction one with the grinding disc 2, the grinding disc 2 rotates and forms a polishing cutting direction two with the workpiece, the left and right moving mechanism 3 drives the workpiece to move left and right and forms a polishing cutting direction three with the grinding disc 2, and the front and back moving mechanism 4 drives the workpiece to move back and forth and forms a polishing cutting direction four with the grinding disc 2. Through the rotation of the front and back moving mechanism 4, the left and right moving mechanism 3, the vacuum tube 8 and the grinding disc 2, four polishing cutting directions are formed on the workpiece, thereby improving the polishing quality and efficiency of the workpiece.

[0036] like Figures 1 to 6 As shown, the front end of the vacuum tube 8 is connected to a clamp 9, and the clamp 9 includes a base 9a connected to the vacuum tube 8. The front end of the base 9a is detachably connected to a connecting seat 9b. Both the base 9a and the connecting seat 9b are rotating bodies. The base 9a is cylindrical, and the front end of the connecting seat 9b is truncated cone-shaped and the rear end is cylindrical.

[0037] like Figure 5 and Figure 6As shown, the base 9a is provided with a vent hole 9a1 which passes through its front end face and rear end face, and the connecting seat 9b is also provided with a vent hole 9b1 which passes through its front end face and rear end face. When the connecting seat 9b is connected to the base 9a, the vent hole 9a1 is connected to the vent hole 9b1, and the front end face of the connecting seat 9b is recessed inwardly and provided with a positioning groove 9b2 which cooperates with the workpiece to be polished. The fixture 9 is installed on the bevel edge polishing machine, and its base 9a1 is connected to the bevel edge polishing machine. The connecting seat 9b is detachably connected to the base 9a. The workpiece to be polished is placed at the front end of the connecting seat 9b and matched with the positioning groove 9b2. The vacuum tube 8 connects the vent hole 1 9a1 and the vent hole 2 9b1. The vacuum system generates negative pressure at the end of the vent hole 2 9b1 to adsorb the workpiece. The positioning groove 9b2 can prevent the workpiece from shifting during the polishing process. When the product is replaced and the original fixture 9 cannot adapt to the new workpiece, the connecting seat 9b can be removed from the base 9a and replaced. There is no need to disassemble the entire fixture 9, so that the fixture 9 can adapt to different workpiece; during the grinding process, if the connecting seat 9b is accidentally worn and the accuracy is reduced, it is only necessary to disassemble and replace the connecting seat 9b; since the height dimensions of the clamp 9 installed on the bevel sweeper are specified to ensure that the workpiece clamped by it can be ground by the grinding disc 2 in a fixed position, if the clamp 9 is integrated, it is necessary to disassemble and replace the integrated clamp 9. Since the connecting seat 9b and the base 9a of the clamp 9 are detachably connected, when the product is replaced or the front end of the clamp 9 is worn, it is sufficient to replace the connecting seat 9b, so that the clamp 9 can be easily replaced to adapt to different production needs and reduce replacement costs.

[0038] like Figure 5 and Figure 6 As shown, the front end of the connecting seat 9b is in a truncated cone shape, and its front diameter is smaller than the rear diameter. When grinding the workpiece, the connecting seat 9b is tilted relative to the grinding disc 2. The front end of the connecting seat 9b is in a truncated cone shape with a smaller diameter at the front and a larger diameter at the back, which can reduce the possibility of collision between the connecting seat 9b and the grinding disc 2 and reduce the possibility of damage to the fixture 9. The positioning groove 9b2 is circular. During the grinding process of the workpiece, the workpiece is placed in the positioning groove 9b2 to limit the workpiece and prevent the workpiece from deviating during the grinding process.

[0039] like Figure 5 and Figure 6As shown, the base 9a and the connecting seat 9b are connected by bolts 9c. Specifically, a threaded hole 9a2 is opened on the base 9a along its axial direction, and a threaded hole 9b3 is opened on the connecting seat 9b along its axial direction. The threaded hole 9a2 and the threaded hole 9b3 can be aligned. The bolts 9c are screwed with the threaded hole 9a2 and the threaded hole 9b3 respectively. A countersunk hole 9b4 communicating with the threaded hole 9b3 is also opened at the front end of the connecting seat 9b. The countersunk hole 9b4 passes through the front end surface of the connecting seat 9b, and the head of the bolt 9c is completely located in the countersunk hole 9b4. When the connecting seat 9b needs to be disassembled, it is only necessary to remove the bolt 9c from the threaded hole 1 9a2 and the threaded hole 2 9b3 to achieve the disassembly of the base 9a and the connecting seat 9b. The countersunk hole 9b4 is set so that the head of the bolt 9c does not protrude relative to the front end surface of the connecting seat 9b. When the workpiece is placed on the front end surface of the connecting seat 9b, the workpiece can fit with the front end surface of the connecting seat 9b to ensure that the workpiece can be reliably adsorbed on the connecting seat 9b.

[0040] The connection seat 9b is made of epoxy board, and the base 9a is made of metal material, such as 40cr or 45 steel. The connection seat 9b is made of epoxy board, which has low cost and is easy to carve, thus reducing the replacement cost.

[0043] Pulleys are provided on the output shaft of the motor 10 and the vacuum tube 8, and the motor 10 and the vacuum tube 8 are driven by a belt.

[0044] The swing mechanism 6 includes a motor mounted on the mounting platform 3 5c. The motor and the cross bar 7 are driven by gears. The motor drives the cross bar 7 to rotate, and the rotation of the cross bar 7 drives the vacuum tube 8 to swing.
