Description

Technical Field

[0001] This invention relates to the field of alloy circular saw blade processing technology, and in particular to a triple-grinding processing device for alloy circular saw blades. Background Technology

[0002] In existing technology, the side angle grinding, front angle grinding, and back angle grinding of carbide circular saw blades are performed on three independently designed side angle grinding machines, front angle grinding machines, and back angle grinding machines. That is, each machine can only complete one grinding process for the carbide circular saw blade. After the previous grinding process is completed, the blade must be manually transferred to the next machine for further grinding. This results in two problems: firstly, the grinding efficiency of carbide circular saw blades is low; secondly, the equipment operating costs are high. For carbide circular saw blade manufacturers, completing the three grinding processes requires the purchase of three machines, thus incurring a heavy burden and hindering cost savings. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a three-stage grinding equipment for alloy circular saw blades, so as to achieve the effect of side angle grinding, front angle grinding and back angle grinding of alloy circular saw blades on the same equipment, thereby improving the grinding efficiency of alloy circular saw blades and reducing equipment operating costs.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A three-stage grinding equipment for alloy circular saw blades includes a machine body, on which are provided a side angle grinding unit, a front angle grinding unit, a rear angle grinding unit, a storage bin, a robotic arm device, and a PLC control system. The robotic arm device, controlled by the PLC control system, moves the alloy circular saw blade to be processed from the storage bin and performs side angle grinding, front angle grinding, and rear angle grinding on the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit, before returning it to the storage bin for storage. The storage bin is provided with an initial blade feeding position, a tooth selection and blade splitting mechanism, and an end blade receiving position. The side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit each include a transfer feeding position, a working position, and a transfer receiving position.

[0006] Furthermore, the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit are arranged side by side on the same side of the machine body, and the storage bin is located on one side of the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit.

[0007] Furthermore, the feed and receive positions of the side angle grinding unit, front angle grinding unit, and rear angle grinding unit are located above and below the storage bin on the side of their respective working positions.

[0008] Furthermore, the working positions of the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit are all arranged facing the storage bin.

[0009] Furthermore, the centers of the feed and receive positions of the side angle grinding unit, front angle grinding unit, and rear angle grinding unit are all located on the same vertical line.

[0010] Furthermore, the tooth selection and slicing mechanism includes a platform and a first slicing suction cup, a second slicing suction cup, and a slicing cylinder disposed on the platform. The second slicing suction cup is connected to the slicing cylinder, and the slicing cylinder can drive the second slicing suction cup to move closer to or away from the first slicing suction cup. It also includes a tooth selection sensor device and a servo motor disposed on the platform. The tooth selection sensor device includes a tooth selection sensor and a sensor position adjustment component. The tooth selection sensor is located on one side of the first slicing suction cup and is used for non-contact detection of the set detection position of the alloy circular saw blade on the first slicing suction cup. The sensor position adjustment component is used to adjust the distance between the tooth selection sensor and the first slicing suction cup. The first slicing suction cup is connected to the servo motor, and the servo motor can drive the first slicing suction cup to rotate by a corresponding angle according to the detection signal of the tooth selection sensor.

[0011] Furthermore, the sensor position adjustment assembly includes a slide rail, a slider, and an adjustment handwheel. The slide rail is fixedly mounted on the platform, the slider is slidably mounted on the slide rail, and the adjustment handwheel is used to lock or release the slider from the slide rail. The tooth selection sensor is mounted on the slider.

[0012] Furthermore, the initial feeding position includes a rectangular support plate and a plurality of first rods arranged in a matrix on the rectangular support plate, and the end receiving position includes an L-shaped support plate facing the rectangular support plate and a plurality of second rods arranged at intervals on the L-shaped support plate. The horizontal part of the L-shaped support plate is parallel to the long side of the rectangular support plate, and the vertical part of the L-shaped support plate is parallel to the wide side of the rectangular support plate.

[0013] Furthermore, the tooth selection and segmentation mechanism is located on the side above the rectangular support plate, close to the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit, while the horizontal and vertical portion of the L-shaped support plate is located on the side above the rectangular support plate, away from the side angle grinding unit, the front angle grinding unit, and the rear angle grinding unit.

[0014] Furthermore, the robotic arm device is a three-axis robotic arm device, which includes an X-axis guide rail, a Y-axis guide rail and a Z-axis guide rail.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, this invention enables the simultaneous grinding of the side angle, front angle, and back angle of alloy circular saw blades on the same equipment, offering advantages such as high automation, significantly improved grinding efficiency, and markedly reduced equipment operating costs for manufacturers.

[0017] Secondly, the side angle grinding unit, front angle grinding unit, and rear angle grinding unit of the present invention all include a transfer feeding position and a transfer receiving position, so that each grinding unit's working position can pre-receive the alloy circular saw blade to be processed through the transfer feeding position during grinding. After the grinding work at the working position is completed, the ground alloy circular saw blade is transferred to the nearest transfer receiving position. Then, the alloy circular saw blade to be processed on the transfer feeding position is transferred to the working position for grinding. Then, the ground alloy circular saw blade on the transfer receiving position is transferred to the next process. This repeated cycle can greatly reduce the time for loading and unloading materials by the robot and intermediate material transfer, thereby further improving work efficiency.

[0024] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0025] like Figures 1 to 6 As shown in the figure, the alloy circular saw blade triple grinding equipment described in this embodiment includes a machine body 1, on which a side angle grinding unit 2, a front angle grinding unit 3, a rear angle grinding unit 4, a storage bin 5, a robotic arm device 6, and a PLC control system are provided.

[0026] The storage bin 5 is equipped with an initial blade feeding position 7, a tooth selection and blade splitting mechanism 8, and an end blade receiving position 9. The initial blade feeding position 7 is used to store the alloy circular saw blades to be processed, and the end blade receiving position 9 is used to store the processed alloy circular saw blades. The tooth selection and blade splitting mechanism 8 is used to split and select the teeth of the alloy circular saw blades to be processed by the robotic arm device 6 when they are loaded onto the grinding equipment. This ensures that the robotic arm device 6 can only pick up one alloy circular saw blade at a time and send it to the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 for grinding. It also ensures that the alloy circular saw blades to be processed can be selected with the teeth to be ground when they are loaded onto the grinding equipment.

[0027] During operation, the PLC control system controls the robotic arm device 6 to first pick up the alloy circular saw blade to be processed stored in the initial feeding position 7 and place it on the tooth selection and splitting mechanism 8 for splitting and tooth selection. Then, after splitting and selecting the teeth to be ground, the single alloy circular saw blade to be processed is moved out of the storage bin 5 and sequentially passes through the side angle grinding unit 2, the front angle grinding unit 3 and the rear angle grinding unit 4 to complete the side angle grinding, front angle grinding and rear angle grinding before being sent back to the storage bin 5 and stored in the end receiving position 9.

[0028] As described above, the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 each include a transfer feed position 10, a working position 11, and a transfer receiving position 12. In this way, during the grinding operation, the working position 11 of each grinding unit can first receive the alloy circular saw blade to be processed through the transfer feed position 10. After the grinding operation of the working position 11 is completed, the ground alloy circular saw blade is transferred to the nearest transfer receiving position 12. Then, the alloy circular saw blade to be processed on the transfer feed position 10 is transferred to the working position 11 for grinding. Then, the ground alloy circular saw blade on the transfer receiving position 12 is transferred to the next process. This repeated cycle can greatly reduce the time for loading and unloading materials by the robot and intermediate material transfer, thereby improving work efficiency.

[0029] As described above, the order of the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 can be adjusted. In other words, the grinding process of the present invention can be adjusted according to design requirements. For example, the side angle grinding unit 2 can be used as the first grinding process, and the front angle grinding unit 3 and the rear angle grinding unit 4 can be used as the second and third grinding processes, respectively. Alternatively, the front angle grinding unit 3 can be used as the first grinding process, and the side angle grinding unit 2 and the rear angle grinding unit 4 can be used as the second and third grinding processes, respectively. Or, the rear angle grinding unit 4 can be used as the first grinding process, and the side angle grinding unit 2 and the front angle grinding unit 3 can be used as the second and third grinding processes, and so on.

[0030] As described above, the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 are arranged side by side on the same side of the machine body 1, and the storage bin 5 is located on one side of the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4.

[0031] Furthermore, the working positions 11 of the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 are all set facing the storage bin 5. The transfer feeding position 10 and the transfer receiving position 12 of the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 are respectively located above and below the side of their working positions 11 closest to the storage bin 5, and the centers of the transfer feeding position 10 and the transfer receiving position 12 of the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4 are all on the same vertical line.

[0032] As described above, the tooth-selecting and splitting mechanism 8 includes a platform 81 and a first splitting suction cup 82, a second splitting suction cup 83, and a splitting cylinder 84 disposed on the platform 81. The second splitting suction cup 83 is connected to the splitting cylinder 84, and the splitting cylinder 84 can drive the second splitting suction cup 83 to move closer to or away from the first splitting suction cup 82. During operation, the robotic arm device 6 grabs the saw blade (i.e., an alloy circular saw blade, or simply saw blade) and places it on the first splitting suction cup 82. It determines whether it is a single piece. If not, the splitting cylinder 84 extends, and at the same time, the second splitting suction cup 83 connected to it is pushed to a position close to the first splitting suction cup 82, so that it and the first splitting suction cup 82 jointly adsorb the saw blade. Then, in conjunction with the robotic arm device 6, the excess saw blade is separated. After the splitting is completed, the splitting cylinder 84 retracts.

[0033] The tooth selection and slicing mechanism 8 also includes a tooth selection sensor device 85 and a servo motor 86 mounted on the platform 81. The tooth selection sensor device 85 includes a tooth selection sensor 851 and a sensor position adjustment component 852. The tooth selection sensor 851 is located on one side of the first slicing suction cup 82 and is used for non-contact detection of the set detection position of the alloy circular saw blade on the first slicing suction cup 82. The sensor position adjustment component 852 is used to adjust the distance between the tooth selection sensor 851 and the first slicing suction cup 82. The first slicing suction cup 82 is connected to the servo motor 86, and the servo motor 86 can drive the first slicing suction cup 82 to rotate by a corresponding angle according to the detection signal of the tooth selection sensor 851.

[0034] Optionally, the tooth selection sensor 851 can be a laser sensor, and the setting detection part of the alloy circular saw blade can be a sprue groove preset around the alloy circular saw blade. During operation, by detecting the sprue groove, the first segment suction cup 82 is driven to rotate at a corresponding angle so that the teeth of the alloy circular saw blade to be ground are rotated to the required position, thereby realizing the automatic tooth selection function.

[0035] Optionally, the sensor position adjustment assembly 852 includes a slide rail 8521, a slider 8522, and an adjustment handwheel 8523. The slide rail 8521 is fixedly mounted on the platform 81, the slider 8522 is slidably mounted on the slide rail 8521, and the adjustment handwheel 8523 is used to lock or release the slider 8522 from the slide rail 8521. The tooth selection sensor 851 is mounted on the slider 8522. When it is necessary to adjust the distance between the tooth selection sensor 851 and the first segmented suction cup 82, simply release the adjustment handwheel 8523, slide the slider 8522 to the desired position, and then lock the adjustment handwheel 8523.

[0036] As described above, the initial feeding position 7 includes a rectangular support plate 71 and a plurality of first sleeve rods 72 arranged in a matrix on the rectangular support plate 71. The first sleeve rods 72 are used for storing the alloy circular saw blades to be processed. The end receiving position 9 includes an L-shaped support plate 91 facing the rectangular support plate 71 and a plurality of second sleeve rods 92 arranged at intervals on the L-shaped support plate 91. The horizontal and vertical portions 911 of the L-shaped support plate 91 are parallel to the long side 711 of the rectangular support plate 71, and the vertical portions 912 of the L-shaped support plate 91 are parallel to the wide side 712 of the rectangular support plate 71. The second sleeve rods 92 are used for storing the processed alloy circular saw blades. This design can make reasonable use of the space of the storage bin 5, allowing more first sleeve rods 72 and second sleeve rods 92 to be set within the limited storage space, thus increasing the saw blade storage positions on the initial feeding position 7 and the end receiving position 9.

[0037] Furthermore, the tooth selection and segmentation mechanism 8 is located on the side of the rectangular support plate 71, near the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4, while the horizontal and vertical part 911 of the L-shaped support plate 91 is located on the side of the rectangular support plate 71, away from the side angle grinding unit 2, the front angle grinding unit 3, and the rear angle grinding unit 4.

[0038] As described above, the robotic arm device 6 is a three-axis robotic arm device, which includes an X-axis guide rail 61, a Y-axis guide rail 62 and a Z-axis guide rail 63. The X-axis guide rail 61, the Y-axis guide rail 62 and the Z-axis guide rail 63 are all located above the side angle grinding unit 2, the front angle grinding unit 3, the rear angle grinding unit 4 and the storage bin 5.

[0039] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention shall still fall within the scope of the patent of the present invention.
