There are many types of picks, and according to different uses and working environments, there are many types and models of picks. Common picks include coal mining picks, rock picks, mining picks, road excavation picks, etc. Picks mainly consist of a shank and a cemented carbide tip. During manufacturing, they generally go through steps such as blanking, forging, tooth body processing, cladding strengthening, alloy hole processing, brazing, heat treatment, shot peening, and inspection. Among them, during cladding strengthening, in addition to using a laser cladding machine to strengthen the tooth body head, a surfacing welding machine is also used for repair.

[0003] In the prior art, most surfacing welding equipment for pick processing lacks the function of orderly automatic feeding and can only rely on workers to manually carry, position, and feed. This not only increases labor costs, interrupts the production process, and reduces overall efficiency, but also manual long-term repetitive labor is prone to operation errors due to fatigue, resulting in deviation of pick positioning during feeding and triggering welding abnormalities.

[0004] Therefore, the present invention provides a surface treatment device and a treatment method for manufacturing coal mine picks. Summary of the Invention

[0020] 1. For the surface treatment device and its treatment method for manufacturing coal mine pick teeth of the present invention, through the cooperation of the arrangement belt with the feeding mechanism, the detection mechanism, and the automatic feeding mechanism, not only the orderly feeding of the pick teeth is realized, but also the cumbersome process of manually placing the pick teeth in the three-jaw chuck, adjusting the form and then fixing them is avoided, reducing the working intensity of the staff and improving the working efficiency.

[0021] 2. For the surface treatment device and its treatment method for manufacturing coal mine pick teeth of the present invention, through the cooperation of the clamping plate with the proximity switch one, the proximity switch two, the motor five, and the rotating seat, the detection and correction of the placement form of the pick teeth during the feeding process are realized, avoiding the incorrect form of the pick teeth when being fixed by the three-jaw chuck, resulting in the surfacing welding machine being unable to recognize and work normally.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Such as Figures 1-9As shown in the figure, a surface treatment device for manufacturing coal mine picks according to an embodiment of the present invention includes a workbench 1. A surfacing welding machine 2 is fixedly installed on the workbench 1. A fixed seat 6 is arranged on one side of the surfacing welding machine 2. The fixed seat 6 is fixedly connected to the top of the workbench 1. A three-jaw chuck 9 is provided on the fixed seat 6. A frame 4 is arranged on one side of the workbench 1. A distribution belt 5 is provided on the frame 4. The distribution belt 5 is driven by two transmission rollers. Both transmission rollers are rotatably connected to the frame 4. Placement grooves are evenly formed in the distribution belt 5. A placement box 25 is arranged in the placement groove. A feeding conveyor 3 is arranged on the side of the frame 4 away from the workbench 1. A material guiding mechanism is arranged between the feeding conveyor 3 and the frame 4. An automatic feeding mechanism is arranged on the side of the frame 4 close to the workbench 1. A detection mechanism is arranged at the middle of the frame 4. An anti-falling plate 42 is fixedly connected to the frame 4. The anti-falling plate 42 is located below the distribution belt 5. A through hole 1 is provided at the center of the three-jaw chuck 9. The inner diameter of the through hole 1 is larger than the outer diameter of the pick. During operation, the feeding conveyor 3 continuously conveys the picks to one side of the workbench 1. When the pick on the workbench 1 is welded and processed by the surfacing welding machine 2, the distribution belt 5 starts to drive, so that a placement box 25 containing a pick passes through the detection mechanism. The placement state of the pick is detected and corrected by the detection mechanism. At the same time, a pick that has been detected moves to the automatic feeding mechanism with the placement box 25 and waits for feeding. Another empty placement box 25 moves to the material guiding mechanism with the drive of the distribution belt 5. At this time, the material guiding mechanism is started, and a pick to be processed is released, so that it slides into the empty placement box 25. The material guiding mechanism is then closed. After the pick on the workbench 1 is welded and processed by the surfacing welding machine 2, the automatic feeding mechanism is started, and the pick in the lower placement box 25 is grabbed and sent to the fixed seat 6, and is fixed by the three-jaw chuck 9 on the fixed seat 6, so as to facilitate the subsequent processing by the surfacing welding machine 2. Through the above structure, not only the orderly feeding of the picks is realized, but also the cumbersome process of manually placing the picks in the three-jaw chuck 9, adjusting the shape and then fixing them when manually loading is avoided, the working intensity of the staff is reduced, the working efficiency is improved, and the problems in the prior art are solved. In the prior art, most surfacing welding equipment for pick processing lacks the function of orderly automatic feeding, and can only rely on manual handling, positioning and feeding by the staff, which not only increases the labor cost, interrupts the production process, and reduces the overall efficiency, but also the long-term repetitive manual labor is prone to operation errors due to fatigue, resulting in deviation of the pick positioning during the feeding process and causing welding abnormalities. The anti-falling plate 42 arranged below the distribution belt 5 can prevent the placement box 25 from falling when it is driven below the distribution belt 5.

[0035] The material guiding mechanism includes a material guiding frame 43, a first material guiding plate 44 and a second material guiding plate 45. A material guiding frame 43 is fixedly connected between the feeding conveyor 3 and the frame 4. There is an opening on the side of the material guiding frame 43 close to the feeding conveyor 3. The first material guiding plate 44 and the second material guiding plate 45 are respectively fixedly connected to the side of the material guiding frame 43 close to the feeding conveyor 3. There is a bottom plate at the bottom of the part of the material guiding frame 43 located between the feeding conveyor 3 and the frame 4. The bottom plate is inclined. The height of the conveyor belt in the feeding conveyor 3 is higher than the height of the arranging belt 5. A rubber pad is inlaid on the inner wall of the side of the material guiding frame 43 close to the arranging belt 5. The first material guiding plate 44 is composed of two straight plates and an inclined plate. The second material guiding plate 45 is composed of an inclined plate and a straight plate. A material blocking component is arranged above the material guiding frame 43. During operation, when the pick is conveyed to the first material guiding plate 44 and the second material guiding plate 45, if the pick is in a state of lying horizontally on the feeding conveyor 3, one end of the pick will continuously rub against the inclined plate on the second material guiding plate 45, causing a speed difference between the two ends of the pick. As a result, the pick begins to be guided by the second material guiding plate 45 and changes to a state of standing vertically on the feeding conveyor 3. Until the pick moves to the inclined plate on the first material guiding plate 44, the pick no longer contacts the inclined plate on the second material guiding plate 45. After that, one end of the pick will continuously rub against the inclined plate on the first material guiding plate 44, causing a speed difference between the two ends of the pick again. Under the guidance of the inclined plate of the first material guiding plate 44, finally the pick can enter between the two straight plates formed by the first material guiding plate 44 and the second material guiding plate 45, ensuring the state of the pick when it enters the placement box 25 and preparing for the state during subsequent surfacing welding. When the arranging belt 5 starts to drive, the material blocking component starts and rises, so that a blocked pick slides down along the bottom plate of the material guiding frame 43 after passing through the material blocking component. After contacting the rubber pad inlaid on the material guiding frame 43, it falls into the empty placement box 25 and waits for subsequent detection. At the same time, after the material blocking component releases a pick, it will fall again to continue blocking the subsequent picks.

[0036] The material blocking component includes a second mounting frame 48, a fourth cylinder 49 and a baffle 50. The two bottom sides of the second mounting frame 48 are respectively fixedly connected to the first material guiding plate 44 and the second material guiding plate 45. A fourth cylinder 49 is fixedly installed at the top of the second mounting frame 48. The output end of the fourth cylinder 49 extends below the second mounting frame 48 and is fixedly connected to a baffle 50. The baffle 50 is located between the first material guiding plate 44 and the second material guiding plate 45. During operation, when the arranging belt 5 starts to drive, the fourth cylinder 49 starts and drives the baffle 50 to rise. After a pick passes through, the fourth cylinder 49 drives the baffle 50 to reset and continue to block the subsequent conveyed picks, realizing orderly feeding.

[0037] The automatic feeding mechanism includes a first fixed frame 13 and a third motor 16. The first fixed frame 13 is fixedly connected to the outer wall of one side of the frame 4 close to the workbench 1. The top of the first fixed frame 13 is fixedly connected to a first support 14. A first lead screw 15 is rotatably connected to the first support 14. A third motor 16 is fixedly installed on the outer wall of the first support 14. The output end of the third motor 16 is fixedly connected to the first lead screw 15. A first nut 17 is threadedly connected to the first lead screw 15. The first nut 17 is slidably connected to the first support 14. A first mounting frame 18 is fixedly connected to the side of the first nut 17 away from the first fixed frame 13. A first cylinder 19 is fixedly installed on the top of the first mounting frame 18. The output end of the first cylinder 19 is fixedly connected to a second support 20. A grasping component is provided on the second support 20. During operation, after the pick teeth on the workbench 1 are completed with surfacing treatment, the first cylinder 19 is started, so that the second support 20 drives the grasping component to descend, and pick teeth in the lower placing box 25 are grasped. After the grasping is completed, the first cylinder 19 drives the grasping component to ascend. The third motor 16 is started, and the first lead screw 15 is driven by the third motor 16 to rotate, so that the first nut 17 drives the first mounting frame 18 and the grasping component to move towards the fixed seat 6 side until the pick teeth completely pass through the first through hole on the three-jaw chuck 9. Then, the third motor 16 stops running, and the three-jaw chuck 9 is started to clamp and fix the handle part of the pick teeth. After that, the grasping component disengages from the pick teeth, and the third motor 16 drives the first lead screw 15 to reverse, so that the first mounting frame 18 and the grasping component are reset, facilitating the next grasping operation.

[0038] The grasping component includes a second lead screw 21 and jaws 24. The second lead screw 21 is rotatably connected to the second support 20. The second lead screw 21 is symmetrically provided with double threads with opposite helix directions. A fourth motor 22 is fixedly installed on the outer wall of the second support 20. The output end of the fourth motor 22 is fixedly connected to the second lead screw 21. A pair of second nuts 23 are threadedly connected to the second lead screw 21. The second nuts 23 are slidably connected to the second support 20. The bottom ends of the pair of second nuts 23 are fixedly connected to jaws 24. The pair of jaws 24 are symmetrically distributed. During operation, when the first cylinder 19 drives the second support 20 to descend, so that the jaws 24 land on both sides of the handle part of the pick teeth, the fourth motor 22 is started and drives the second lead screw 21 to rotate, so that the two jaws 24 slide relatively, completing the clamping and fixing of the handle part of the pick teeth. When the three-jaw chuck 9 completes the fixing of the pick teeth, the fourth motor 22 drives the second lead screw 21 to reverse, so that the two jaws 24 slide in the opposite direction, releasing the clamping of the pick teeth, facilitating the third motor 16 to drive it to reset and prepare for the next grasping and feeding.

[0039] The detection mechanism includes the second cylinder 27, the rotating seat 31 and the clamping plate 38. The second cylinder 27 is fixedly installed in the middle of the inner cavity of the frame 4. The output end of the second cylinder 27 is fixedly connected with the lifting seat 28. A flipping assembly is arranged on the lifting seat 28. The middle of the outer wall of the frame 4 is fixedly connected with the second fixing frame 34. The bottom of one end of the second fixing frame 34 is rotatably connected with the third support 35. A support rod 36 is fixedly connected to the third support 35. A pair of support plates 37 are slidably connected to the support rod 36. A spring 39 is fixedly connected between the support plate 37 and the inner side wall of the third support 35. The bottom end of the support plate 37 is fixedly connected with the clamping plate 38. The bottom of the clamping plate 38 is arc-shaped. During operation, when the placement box 25 located at the material guiding frame 43 receives the pick teeth and moves to the position of the second cylinder 27 along with the transmission of the arranging belt 5, the arranging belt 5 stops. At this time, the placement box 25 is directly below the two clamping plates 38. The second cylinder 27 starts and drives the lifting seat 28 to rise. During the rising process of the lifting seat 28, it contacts the bottom of the placement box 25 and drives the placement box 25 to slide upward together until the two clamping plates 38 penetrate into the placement box 25. Since the outer diameter of the end of the pick teeth corresponding to the clamping plates 38 is larger than the outer diameter of the pick tooth shank at this time, if the pick teeth in the placement box 25 are in the state of the end in the front and the shank in the back, the two clamping plates 38 are just on both sides of the pick tooth shank and do not contact after penetrating into the placement box 25, and the switch will not be triggered, that is, the placement form of the pick teeth meets the form during subsequent surfacing. Then, the second cylinder 27 drives the lifting seat 28 to descend, so that the placement box 25 is reset accordingly. If the pick teeth in the placement box 25 are in the state of the end in the back and the shank in the front, the two clamping plates 38 will contact and be squeezed by the ends of the pick teeth after penetrating into the placement box 25, causing the two clamping plates 38 to slide in the reverse direction and squeeze the spring 39 until the contact switches 41 on the two clamping plates 38 are respectively in contact with the contact switches 40 on both sides of the third support 35, and then the flipping assembly on the lifting platform starts and drives the placement box 25 to rotate 180°, so that the pick teeth are in the state of the end in the front and the shank in the back, which is convenient for subsequent surfacing.

[0040] The flipping component includes motor five 29 and rotating seat 31. Motor five 29 is fixedly installed at the top of lifting seat 28. The output end of motor five 29 is fixedly connected with gear two 30. The top of lifting seat 28 is rotatably connected with rotating seat 31. Ring gear two 32 is fixedly connected to rotating seat 31. Gear two 30 is meshed with ring gear two 32. A clamping block 33 is fixedly connected to the top of rotating seat 31. A clamping groove 26 is formed at the bottom of placing box 25. Clamping block 33 is adapted to clamping groove 26. During operation, when both two contact switches one 40 and two contact switches two 41 are in contact, motor five 29 starts. Gear two 30 is driven by motor five 29 to rotate, so that ring gear two 32 drives rotating seat 31 to rotate accordingly. Also, because clamping block 33 on rotating seat 31 is adapted to clamping groove 26 at the bottom of placing box 25, placing box 25 rotates accordingly. At the same time, since two clamping plates 38 are located on both sides of the pick handle, when placing box 25 drives the pick to rotate, clamping plate 38 drives support three 35 to rotate accordingly. Until after rotating 180°, both placing box 25 and support three 35 stop rotating. Then placing box 25 resets. Clamping plate 38 on support three 35 continues to detect the shape of the next passing pick, ensuring the shape during pick surfacing. Due to the rotational friction force between support three 35 and fixed frame two 34, support three 35 can only rotate when motor five 29 starts.

[0041] A through groove is provided on material guide plate two 45. The length of the through groove is the same as the sum of the lengths of one straight plate and one inclined plate of material guide plate one 44. An air cylinder three 46 is fixedly installed on feeding conveyor 3 on one side of material guide plate two 45. The output end of air cylinder three 46 is fixedly connected with a pushing rod 47. Pushing rod 47 is adapted to the through groove. During operation, when the pick passes through material guide plate two 45, air cylinder three 46 drives pushing rod 47 to make reciprocating sliding, so that pushing rod 47 can guide the shape of the passing pick, avoiding the pick being stuck at the inlets of material guide plate one 44 and material guide plate two 45.

[0042] A mounting plate 7 is rotatably connected to the fixed seat 6. A first motor 8 is fixedly installed on an outer wall of one side of the fixed seat 6. The output end of the first motor 8 is fixedly connected to the mounting plate 7. A three-jaw chuck 9 is rotatably connected to the mounting plate 7. A first toothed ring 12 is fixedly connected to the three-jaw chuck 9. A second motor 10 is fixedly installed on a side of the mounting plate 7 away from the surfacing welding machine 2. The output end of the second motor 10 penetrates through the mounting plate 7 and is fixedly connected to a first gear 11. The first gear 11 is meshed with the first toothed ring 12. A second through hole is provided at the center of the mounting plate 7, and the inner diameter of the second through hole is the same as the inner diameter of the first through hole. During operation, when the pick passes through the second through hole on the mounting plate 7 and the first through hole on the three-jaw chuck 9, the three-jaw chuck 9 is started to clamp and fix the handle of the pick. After the fixing is completed, the first motor 8 drives the mounting plate 7 to rotate, so that the end of the pick is tilted upward, facilitating the operation of the surfacing welding machine 2. When the surfacing welding machine 2 performs welding treatment on the end of the pick, the second motor 10 is started and drives the first gear 11 to rotate, so that the first toothed ring 12 drives the three-jaw chuck 9 to rotate accordingly, and then the pick rotates, facilitating the surfacing welding machine 2 to perform all-round treatment on the end of the pick.

[0043] A surface treatment method for manufacturing coal mine picks, which is applicable to the above-mentioned surface treatment device for manufacturing coal mine picks. The treatment method includes the following steps:

[0044] S1: The picks are continuously conveyed to one side of the workbench 1 through the feeding conveyor 3. The pick blocking assembly can discharge the picks in an orderly manner. The picks passing through the pick blocking assembly slide into the guide frame 43 and then enter the empty placement box 25 on the arrangement belt 5.

[0045] S2: When the surfacing welding machine 2 starts to perform surfacing welding treatment on the pick on the three-jaw chuck 9, the arrangement belt 5 is started. An empty placement box 25 is driven by the arrangement belt 5 to be below the guide frame 43 again. At the same time, a placement box 25 containing picks and not yet detected moves to the detection mechanism, and the detection mechanism detects and corrects the placement form of the picks. A placement box 25 containing picks that has completed detection moves to the automatic feeding mechanism and waits for feeding.

[0046] S3: After the surfacing welding machine 2 finishes processing one pick and unloads it, the automatic feeding mechanism takes out the pick waiting for feeding from the placement box 25 and transfers it into the three-jaw chuck 9 for fixation, waiting for the surfacing welding machine 2 to complete the surfacing welding treatment.

[0047] Working principle: The feeding conveyor 3 continuously conveys the pick teeth to one side of the workbench 1. When the pick teeth on the workbench 1 are welded by the surfacing welding machine 2, the arranging belt 5 starts to drive, so that a placement box 25 containing pick teeth passes through the detection mechanism. The detection mechanism detects and corrects the placement form of the pick teeth. At the same time, a pick tooth that has been detected moves with the placement box 25 to the automatic feeding mechanism to wait for feeding. Another empty placement box 25 moves to the material guiding mechanism with the drive of the arranging belt 5. At this time, the material guiding mechanism starts and releases a pick tooth to be processed, so that it slides into the empty placement box 25. Then the material guiding mechanism closes. After the pick teeth on the workbench 1 are welded by the surfacing welding machine 2, the automatic feeding mechanism starts, grabs the pick teeth in the lower placement box 25 and sends them to the fixed seat 6, and fixes them through the three-jaw chuck 9 on the fixed seat 6, which is convenient for the subsequent processing of the surfacing welding machine 2. Through the above structure, not only the orderly feeding of the pick teeth is realized, but also the cumbersome process of manually placing the pick teeth in the three-jaw chuck 9 and adjusting the form before fixing is avoided, reducing the work intensity of the staff and improving the work efficiency. The anti-falling plate 42 arranged below the arranging belt 5 can prevent the placement box 25 from falling when it is driven below the arranging belt 5. When the pick teeth are conveyed to the material guiding plate 1 44 and the material guiding plate 2 45, if the pick teeth are in a state of lying horizontally on the feeding conveyor 3, one end of the pick teeth will continuously rub against the inclined plate on the material guiding plate 2 45, causing a speed difference between the two ends of the pick teeth. Then the pick teeth start to be guided by the material guiding plate 2 45 to change to a state of standing vertically on the feeding conveyor 3. Until the pick teeth move to the inclined plate on the material guiding plate 1 44, the pick teeth no longer contact the inclined plate on the material guiding plate 2 45. After that, one end of the pick teeth will continuously rub against the inclined plate on the material guiding plate 1 44, causing a speed difference between the two ends of the pick teeth again. Under the guidance of the inclined plate of the material guiding plate 1 44, finally the pick teeth can enter between the two straight plates composed of the material guiding plate 1 44 and the material guiding plate 2 45, ensuring the form of the pick teeth when they enter the placement box 25 and preparing for the form during subsequent surfacing welding. When the arranging belt 5 starts to drive, the cylinder 4 49 starts and drives the baffle 50 to rise, so that a blocked pick tooth slides down along the bottom plate of the material guiding frame 43 after passing through the baffle 50. After contacting the rubber pad embedded on the material guiding frame 43, it falls into the empty placement box 25 and waits for subsequent detection. After allowing one pick tooth to pass, the cylinder 4 49 drives the baffle 50 to reset and continues to block the pick teeth conveyed subsequently, realizing orderly feeding. When the placement box 25 located at the material guiding frame 43 receives the pick teeth and moves to the cylinder 2 27 with the drive of the arranging belt 5, the arranging belt 5 stops running, and the cylinder 2 27 starts and drives the lifting seat 28 to rise. During the rising process of the lifting seat 28, it contacts the bottom of the placement box 25 and drives the placement box 25 to slide upward together until the two clamping plates 38 penetrate into the placement box 25. If the pick teeth in the placement box 25 are in a state where the end is in front and the handle is behind, after the two clamping plates 38 penetrate into the placement box 25, they are exactly on both sides of the pick tooth handle and do not contact.The switch will not be triggered, that is, the placement form of the pick teeth meets the form during subsequent surfacing. After that, the cylinder two 27 drives the lifting seat 28 to descend, causing the placement box 25 to reset accordingly. If the pick teeth in the placement box 25 are in the state where the end is at the back and the shank is at the front, after the two clamping plates 38 penetrate into the placement box 25, they will contact and be squeezed by the ends of the pick teeth, causing the two clamping plates 38 to slide reversely and squeeze the spring 39 until the contact switches two 41 on the two clamping plates 38 respectively fit with the contact switches one 40 on both sides of the support three 35, then the motor five 29 starts. The motor five 29 drives the gear two 30 to rotate, causing the gear ring two 32 to drive the rotating seat 31 to rotate accordingly. Also, because the clamping blocks 33 on the rotating seat 31 are adapted to the card slots 26 at the bottom of the placement box 25, the placement box 25 rotates accordingly. At the same time, since the two clamping plates 38 are located on both sides of the shank of the pick teeth, when the placement box 25 drives the pick teeth to rotate, the clamping plates 38 drive the support three 35 to rotate accordingly. Until after rotating 180°, both the placement box 25 and the support three 35 stop rotating. The placement box 25 then resets, and the clamping plates 38 on the support three 35 continue to detect the form of the next passing pick teeth to ensure the form during pick teeth surfacing. After the pick teeth on the workbench 1 are completed with surfacing treatment, the cylinder one 19 starts, causing the support two 20 to drive the grasping component to descend to grasp the pick teeth in the lower placement box 25. After completing the grasping, the cylinder one 19 drives the grasping component to rise. The motor three 16 starts, and the motor three 16 drives the lead screw one 15 to rotate, causing the lead screw sleeve one 17 to drive the mounting frame one 18 and the grasping component to move towards the fixed seat 6 side until the pick teeth completely pass through the through hole one on the three-jaw chuck 9, then the motor three 16 stops. The three-jaw chuck 9 starts to clamp and fix the shank of the pick teeth. After that, the grasping component disengages from the pick teeth, and the motor three 16 drives the lead screw one 15 to reverse, causing the mounting frame one 18 and the grasping component to reset, facilitating the next grasping work. When the cylinder one 19 drives the support two 20 to descend, causing the jaws 24 to land on both sides of the shank of the pick teeth, the motor four 22 starts and drives the lead screw two 21 to rotate, causing the two jaws 24 to slide relatively to complete the clamping and fixing of the shank of the pick teeth. When the three-jaw chuck 9 completes the fixing of the pick teeth, the motor four 22 drives the lead screw two 21 to reverse, causing the two jaws 24 to slide reversely to release the clamping of the pick teeth, facilitating the motor three 16 to drive it to reset and prepare for the next grasping and feeding. When the pick teeth pass through the through hole two on the mounting plate 7 and the through hole one on the three-jaw chuck 9, the three-jaw chuck 9 starts to clamp and fix the shank of the pick teeth. After completing the fixing, the motor one 8 drives the mounting plate 7 to rotate, causing the end of the pick teeth to tilt upward, facilitating the operation of the surfacing machine 2. When the surfacing machine 2 performs welding treatment on the end of the pick teeth, the motor two 10 starts and drives the gear one 11 to rotate, causing the gear ring one 12 to drive the three-jaw chuck 9 to rotate accordingly, and then causing the pick teeth to rotate, facilitating the surfacing machine 2 to perform all-round treatment on the end of the pick teeth. When the pick teeth pass through the guide plate two 45, the cylinder three 46 drives the push rod 47 to slide reciprocally.The pusher rod 47 can guide the shape of the passing picks, avoiding the picks from getting stuck at the inlets of the first guide plate 44 and the second guide plate 45.
