Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, in particular to an automatic loading and unloading device for a double-end surface grinding machine. Background Art

[0002] Double-end face grinder is a highly efficient plane processing machine tool, which can grind two parallel end faces at the same time in one processing process. It can be divided into horizontal and vertical types according to the structure, and can be divided into through-type, rotary table type and reciprocating type according to the feeding method.

[0003] The existing wheel-type double-end surface grinder consists of two upper and lower grinding discs, of which the upper grinding disc can be removed, and the lower grinding disc is divided into an inner circle and an outer circle, and the edges of the inner circle and the outer circle are provided with circular rollers arranged in a circumferential array. The workpiece is placed in a special toothed disc, and an empty groove that fits the workpiece is opened in the toothed disc. The toothed disc is placed between the inner circle and the outer circle, and the teeth on the toothed disc mesh with the circular rollers of the inner circle and the outer circle. Subsequently, the upper grinding disc is reset, and the upper and lower surfaces of the workpiece are ground by the upper and lower grinding discs rotating in opposite directions;

[0004] The existing loading method is to first lower a round roller at the edge of the lower grinding disc so that the loading tray fits the edge of the lower grinding disc, then place the workpiece in the empty slot of the loading toothed disc, and then push the toothed disc loaded with workpieces through the edge of the lower grinding disc, and make the edges of the toothed disc mesh with the round sticks on the inner circle and the outer circle respectively, start the motor to drive the inner circle to rotate, so that the toothed disc drives the workpiece into the turntable track, and repeats this process, and finally lifts the round stick at the edge of the lower grinding disc to start grinding. After grinding, take out the toothed disc in the reverse direction. This loading and unloading method requires manual operation. The overall process is inefficient due to manual operation, and it needs to be manually aligned with the loading toothed disc and the round stick, which is more troublesome to operate.

[0005] Therefore, we propose an automatic loading and unloading device for double-end surface grinder. Summary of the invention

[0024] Preferably, the toothed disc carrier is provided with an annular groove at the bottom of the workpiece.

[0025] The present invention has at least the following beneficial effects:

[0026] 1. The toothed column at the feeding port of the lower grinding disc is used as the center of the circle to cooperate with the driving rod and the rotating mechanism to rotate the toothed disc carrier into the lower grinding disc, which can replace manual operation and reduce manual work. After the toothed disc carrier enters the lower grinding disc, the meshing process has been completed. Therefore, when the toothed column at the edge of the lower grinding disc rises, the probability of the toothed disc carrier edge teeth rising will be reduced;

[0027] 2. When the rotating wheel cooperates with the concave plate to descend and abut against the toothed disc carrier, the toothed part at the middle edge of the rotating wheel will mesh with the teeth in the circular groove of the toothed disc carrier. When the motor drives the rotating wheel to rotate, the toothed part cooperates with the teeth to increase the friction between the rotating wheel and the toothed disc carrier, thereby making it difficult for the toothed disc carrier to slip during the rotation process.

[0028] 3. By fixing a disc made of a strong magnetic material in the circular groove of the toothed disc carrier, and also making the rotating wheel part of a strong magnetic material, when the concave plate and the rotating wheel part are lowered to a certain height, the rotating wheel part made of a strong magnetic material can absorb the toothed disc carrier, thereby reducing the pressure of the toothed disc carrier on the material carrier plate and the lower grinding disc. In this way, when the motor 3 drives the rotating wheel part to rotate, the static friction between the toothed disc carrier and the material carrier plate and the lower grinding disc is reduced, which is convenient for the rotating wheel part to drive the toothed disc carrier to rotate;

[0029] 4. During the grinding process, the coolant is sprayed into the grinding area through the nozzle. The arc-shaped part will move with the movement of the gear disc carrier and always fit the edge of the lower grinding disc. The spray assembly on the arc-shaped part can re-spray the excess coolant on the end face of the workpiece. Since the arc-shaped part is always at the edge of the lower grinding disc, the re-sprayed coolant is mainly targeted at the outer edge of the lower grinding disc, so it can effectively reduce the heat generated in this part of the grinding area.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to better understand the automatic loading and unloading device of the double-end face grinder provided by the embodiment of the present application, the following first briefly introduces the application of the existing double-end face grinder in grinding workpieces. The existing loading and unloading method is basically manual operation. When operating the double-end face grinder, first lower the toothed column at the feed port of the lower grinding disc to expose the feed port. Then, push the loading plate full of workpieces to the feed port of the lower grinding disc and align it with the surface of the lower grinding disc. Next, push the toothed disc carrier into the lower grinding disc. During the pushing process, the teeth on the edge of the toothed disc carrier need to be meshed with the toothed columns on the inner and outer edges of the lower grinding disc. After meshing, by pressing the control member, the rotating disc rotates and the toothed disc carrier is screwed in, so that the next toothed disc carrier can enter. When the last toothed disc carrier needs to be placed, it is only necessary to align the teeth of the toothed disc carrier with the toothed columns on the edge of the rotating disc. Then, the toothed column at the edge of the feed port of the lower grinding disc is raised. However, it is difficult to align the teeth on the edge of the toothed disc object carrier with the gaps in the toothed column by manual operation, and the toothed column often lifts up the toothed disc object carrier when it is raised, requiring manual resetting.

[0044] When all the gear discs are loaded, the upper grinding disc is reset and works with the lower grinding disc to grind the upper and lower end surfaces of the workpieces on the gear disc. During the grinding process, the nozzles at the edge of the upper grinding disc will continue to spray coolant on the grinding area. The coolant can quickly remove the high temperature generated during the grinding process to prevent the workpiece from being deformed or damaged due to overheating. At the same time, the coolant can also wash away the fine particles and fallen sand generated during the grinding process to maintain the grinding performance of the grinding wheel.

[0045] During the grinding process, the gear wheel carrier rotates while revolving around the lower grinding wheel. Therefore, when the upper and lower grinding wheels grind the upper and lower end faces of the workpiece in opposite directions, the outer circle speed of the upper and lower grinding wheels is greater than the inner circle speed. The grinding area near the edge of the grinding wheel generates more heat, and the coolant may not be able to take away the heat in time, resulting in local overheating of the workpiece surface and burns.

[0046] Example 1: Please refer to Figure 1-11 The present invention provides a technical solution: an automatic loading and unloading device for a double-end surface grinder, comprising:

[0047] A main housing 10, wherein a lower grinding disc 11 is disposed on the top of the main housing 10, and a rotating disc 12 is rotatably connected to the middle of the lower grinding disc 11;

[0048] It should be noted that the lower grinding disc 11 is rotatably connected to the top of the main housing 10, the rotating disc 12 is rotatably connected to the main housing 10, an upper grinding disc is also provided on the top of the main housing 10, and the upper grinding disc rotates in the opposite direction to the lower grinding disc 11, and a nozzle is also provided at the edge of the upper grinding disc, and a cooling device is also provided in the main housing 10, and the cooling device sprays the coolant through the nozzle on the grinding area to complete the functions of cooling, etc., all of the above are prior arts and will not be described in detail here;

[0049] A feeding mechanism 20, which is disposed on one side of the main housing 10, and is used to push the toothed disc carrier 30 to the feed port of the lower grinding disc 11;

[0050] A toothed disc object carrier 30, wherein the toothed disc object carrier 30 is used for placing a workpiece;

[0051] The connection assembly 40 is arranged on one side of the feeding mechanism 20, and the connection assembly 40 includes:

[0052] A fixed frame 41, one side of the fixed frame 41 is fixedly connected to an electric cylinder 1 42, a slide groove is provided in the fixed frame 41, the telescopic rod inside the electric cylinder 1 42 extends into the slide groove of the fixed frame 41, the end of the telescopic rod inside the electric cylinder 1 42 is fixedly connected to a moving block 43, a driving rod 44 is rotatably connected to the moving block 43, a gear 1 45 is fixedly connected to the bottom of the driving rod 44, the moving block 43 is located at the other side of the driving rod 44 and is fixedly connected to a motor 1 46, the end of the internal rotating shaft of the motor 1 46 is fixedly connected to a gear 2 47, the gear 2 47 is meshed with the gear 1 45, the end of the driving rod 44 away from the fixed frame 41 is fixedly connected to an electric cylinder 2 48, the end of the telescopic rod inside the electric cylinder 2 48 is fixedly connected to a concave plate 49, and both ends of the concave plate 49 are provided with a rotating mechanism 50 for rotating the toothed disc carrier 30;

[0053] It should be noted that the feeding mechanism 20 pushes the toothed disc carrier 30 filled with workpieces to the feed port of the lower grinding disc 11. In the initial state, the concave plate 49 is perpendicular to the edge of the fixed frame 41. When the toothed disc carrier 30 is transported to the bottom of the concave plate 49, the concave plate 49 is moved closer to the toothed disc carrier 30 through the internal telescopic rod of the electric cylinder 2 48, so that the rotating mechanism 50 contacts the toothed disc carrier 30. At this time, the electric cylinder 1 42 is started, and the internal telescopic rod of the electric cylinder 1 42 drives the moving block 43 to move along the direction of the fixed frame 41. When the moving block 43 reaches the end of the stroke, the motor 1 46 drives the gear 2 47 to rotate, and the gear 2 47 drives the gear 1 45 to rotate. At this time, the driving rod 44 is driven by the gear 2 47 to rotate. During the rotation process, the rotating mechanism 50 still drives the gear disc carrier 30 to rotate, and the center of the gear 1 45 coincides with the center of the toothed column of the feed port of the lower grinding disc 11. The driving rod 44 cooperates with the rotating mechanism 50 to rotate the gear disc carrier 30. The toothed column at the feed port of the lower grinding disc 11 rotates as the center of a circle until the teeth on the edge of the toothed disc carrier 30 mesh with the toothed column at the edge of the rotating disc 12, and then the rotating disc 12 is started to allow the toothed disc carrier 30 to enter the grinding area and leave the feed port of the lower grinding disc 11 empty for the next toothed disc carrier 30 to enter. After the last toothed disc carrier 30 enters, the toothed column at the edge of the lower grinding disc 11 is raised to start grinding. When the grinding is completed, the toothed column at the edge of the lower grinding disc 11 is lowered to control the rotating disc 12. When the teeth on the edge of the toothed disc object carrier 30 are about to separate from the rotating disc 12 and the toothed columns on the edge of the lower grinding disc 11, the concave plate 49 is lowered by the electric cylinder 2 48, and the rotating mechanism 50 at the bottom of the concave plate 49 is in contact with the toothed disc object carrier 30, and the driving rod 44 is driven to rotate by the motor 1 46, and the driving rod 44 cooperates with the rotating mechanism 50 to rotate the toothed disc object carrier 30 out of the lower grinding disc 11, and cooperates with the feeding mechanism 20 to transport the toothed disc object carrier 30 to the next process to complete the unloading work;

[0054] It is worth noting that the toothed column at the feed port of the lower grinding disc 11 is used as the center of the circle to cooperate with the driving rod 44 and the rotating mechanism 50 to rotate the toothed disc carrier 30 into the lower grinding disc 11, which can replace manual operation and reduce manual work. After the toothed disc carrier 30 enters the lower grinding disc 11, the meshing process is completed. Therefore, when the toothed column at the edge of the lower grinding disc 11 rises, the probability of the toothed disc carrier 30 rising at the edge will be reduced.

[0055] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the feeding mechanism 20 comprises:

[0056] A support frame 21, one side of the support frame 21 is fixedly connected to one side of the feed port of the main shell 10, a loading plate 22 is slidably connected to the top of the support frame 21, a tooth column 23 is arranged in an array at the edge of the loading plate 22, the tooth column 23 is fixedly connected to the loading plate 22, a gear member 24 is rotatably connected to the loading plate 22, the bottom of the gear member 24 extends to the outside of the loading plate 22, a motor 25 is fixedly connected to the bottom of the loading plate 22, the end of the internal rotating shaft of the motor 25 is fixedly connected to the bottom of the gear member 24, a chain 27 is meshed outside the gear member 24, a tooth column 26 is arranged in a circumferential array on the chain 27, and the tooth column 26 is rotatably connected to the chain 27;

[0057] It should be noted that, in the initial state, the toothed disc carrier 30 is arranged on the carrier plate 22 in sequence, and the edge teeth of the toothed disc carrier 30 are meshed with the gear column 1 23 and the gear column 2 26. The staff places the workpieces in the workpiece slot of the toothed disc carrier 30 in sequence through a robot or manual operation, and drives the gear part 24 to rotate through the motor 25, and the gear part 24 drives the chain 27 to rotate. The chain 27 cooperates with the gear column 26 and the gear column 1 23 to drive the toothed disc carrier 30 to move and rotate along the direction of the carrier plate 22. By controlling the rotation direction of the motor 2 25, the movement and rotation direction of the toothed disc carrier 30 can be controlled, thereby completing the loading and unloading process.

[0058] Further Figure 4 and Figure 5 As shown, it is worth to explain in detail that the rotating mechanism 50 includes:

[0059] Motor three 51, the housing of the motor three 51 is fixedly connected to the top of the concave plate 49, the end of the concave plate 49 is rotatably connected to a rotating wheel 52, the connecting shaft of the rotating wheel 52 extends out of the concave plate 49, the connecting shaft of the rotating wheel 52 is connected to the end of the internal rotating shaft of the motor three 51 through a driving belt 53, and a circular groove 54 is opened on the top of the toothed disc carrier 30;

[0060] By bringing the rotating wheel part 52 into contact with the circular groove 54 on the top of the toothed disc carrier 30 and starting the motor three 51, the internal rotating shaft of the motor three 51 drives the driving belt 53 to rotate, and the driving belt 53 drives the rotating wheel part 52 to rotate. By controlling the rotation direction and rotation speed of the motor three 51 on both sides, the action of translation and rotation along the direction of the carrier plate 22 or the rotation action with the toothed column at the feed port of the lower grinding disc 11 as the center can be completed, thereby achieving the purpose of meshing the toothed disc carrier 30 with the toothed column at the edge of the lower grinding disc 11.

[0061] Further as Figure 5 As shown, it is worth to explain in detail that the toothed disc carrier 30 is provided with toothed members 55 in a circumferential array in the circular groove 54, and the central circumferential array of the rotating wheel member 52 is provided with teeth 56;

[0062] It should be noted that when the rotating wheel member 52 cooperates with the concave plate 49 to descend and abut against the sprocket carrier 30, the toothed member 55 at the middle edge of the rotating wheel member 52 will engage with the teeth 56 of the sprocket carrier 30 located in the circular groove 54. Therefore, when the motor three 51 drives the rotating wheel member 52 to rotate, the toothed member 55 cooperates with the teeth 56 to increase the friction between the rotating wheel member 52 and the sprocket carrier 30, thereby making the sprocket carrier 30 less likely to slip during the rotation.

[0063] Further as Figure 5 As shown, it is worth to explain in detail that the toothed disc carrier 30 is located at the circular groove 54 and is fitted with a disc 57, and the disc 57 and the rotating wheel 52 are both made of strong magnetic material;

[0064] It should be noted that, by fixing a disc member 57 made of a strong magnetic material in the circular groove 54 of the toothed disc carrier 30, and making the rotating wheel member 52 also of a strong magnetic material, when the concave plate 49 cooperates with the rotating wheel member 52 to descend to a certain height, the rotating wheel member 52 made of a strong magnetic material can absorb the toothed disc carrier 30, thereby reducing the pressure of the toothed disc carrier 30 on the carrier plate 22 and the lower grinding disc 11. In this way, when the motor three 51 drives the rotating wheel member 52 to rotate, the static friction between the toothed disc carrier 30 and the carrier plate 22 and the lower grinding disc 11 is reduced, which facilitates the rotating wheel member 52 to drive the toothed disc carrier 30 to rotate.

[0065] Embodiment 2: Further as Figure 5 As shown, it is worth to explain in detail that a cooling component 60 is arranged in the toothed disc object carrier 30, and the cooling component 60 includes:

[0066] The arc-shaped member 61 is arranged in the middle of the toothed disc object carrier 30, the arc-shaped member 61 is rotatably connected to the toothed disc object carrier 30, and a spraying assembly 70 is arranged on the side of the arc-shaped member 61 close to the center of the toothed disc object carrier 30, and the spraying assembly 70 is used to spray the excess coolant to the end face of the workpiece again;

[0067] It should be noted that during the grinding process, the coolant is sprayed into the grinding area through the nozzle, and the arc-shaped member 61 moves with the movement of the toothed disc carrier 30 and is always attached to the edge of the lower grinding disc 11. The spraying assembly 70 on the arc-shaped member 61 can re-spray excess coolant on the end face of the workpiece. Since the arc-shaped member 61 is always at the edge of the lower grinding disc 11, the re-sprayed coolant is mainly targeted at the outer edge of the lower grinding disc 11, thereby effectively reducing the heat generated in this part of the grinding area.

[0068] Further Figure 7 and Figure 8 As shown, it is worth explaining in detail that the outer wall of the arc-shaped member 61 fits with the toothed column on the edge of the lower grinding disc 11, and the bottom of the arc-shaped member 61 is rotatably connected with a sprocket 62, and the sprocket 62 meshes with the toothed column on the outer edge of the lower grinding disc 11;

[0069] It should be noted that by designing the curvature of the outer wall of the arc-shaped member 61 to be the same as the curvature of the edge of the lower grinding disc 11, when the toothed disc carrier 30 revolves and rotates in the grinding area of ​​the lower grinding disc 11, the arc-shaped member 61 will not rotate during this process. The chain teeth 62 at the bottom of the arc-shaped member 61 engage with the toothed columns of the lower grinding disc 11 to prevent the arc-shaped member 61 from rotating during the grinding process, thereby maintaining relative stability.

[0070] Further Figure 8 , Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the spraying assembly 70 includes:

[0071] The motor 4 71 is built into the arc-shaped member 61. A cavity is formed on one side of the arc-shaped member 61. An impeller 72 is fixedly connected to the end of the rotating shaft inside the motor 4 71. A spraying member 73 is fixedly connected to one side of the impeller 72 of the arc-shaped member 61. The spraying member 73 is in a concave shape and is in communication with the cavity of the arc-shaped member 61.

[0072] It should be noted that a power supply device is placed in the arc-shaped member 61, and the power supply device is used to supply power to the motor 4 71. The motor 4 71 drives the impeller 72 to rotate, and the impeller 72 pushes the coolant in the cavity of the arc-shaped member 61 into the spraying member 73, and the spraying member 73 sprays the coolant on the end surface of the workpiece, thereby achieving the purpose of cooling.

[0073] It is worth noting that by designing the spray piece 73 to be concave in shape, the coolant sprayed from the spray piece 73 can act on the upper and lower end faces of the workpiece at the same time, thereby cooling the upper and lower end faces of the workpiece at the same time, and in conjunction with the arc-shaped piece 61, the upper and lower end faces of the workpiece in the grinding area close to the outer ring with a higher linear speed can be quickly cooled, thereby avoiding burning of the workpiece end faces due to excessive outer ring linear speed.

[0074] Further Fig. 9 and Fig.10 As shown, it is worth to explain in detail that the arc-shaped member 61 is located at the top of the impeller 72 and is connected to a pipe 74, and a water collecting plate 75 is fixedly connected to the top of the pipe 74. The water collecting plate 75 is circular, and the inner bottom wall of the water collecting plate 75 is inclined;

[0075] It should be noted that the water collecting plate 75 can rotate with the gear wheel carrier 30 as the center. When the coolant falls onto the water collecting plate 75, the coolant can flow into the pipe 74 through the water collecting plate 75 and finally enter the cavity in the arc-shaped part 61, thereby completing the collection purpose. By designing the water collecting plate 75 to be circular, the collection area can be increased.

[0076] Further Fig.11 As shown, it is worth explaining in detail that the toothed disc carrier 30 is provided with an annular groove 76 at the bottom of the workpiece, and the annular groove 76 is formed to fit the actual shape of the workpiece. By providing the annular groove 76 at the bottom of the toothed disc carrier 30, when the coolant is sprayed through the spray part 73, the coolant can enter the annular groove 76. With this design, the bottom end face of the workpiece can be cooled by the coolant all around.
