Description

Technical Field

[0001] This invention relates to the field of track link processing technology, specifically to a loading and unloading device for processing track links. Background Technology

[0002] Track links are the connecting parts in the tracks of engineering machinery. The production process of track links is as follows: blanking → die forging → punching and trimming → heat treatment → milling of both sides → boring → drilling bolt holes → pushing nut surface. Track links are forged and processed on the production line. After precision grinding, track links are transported to the MT inspection area via conveyor rails for MT flaw detection after forging.

[0003] For example, a conveying device for track links, disclosed in CN117401402B, includes a conveying track with an outer frame fixedly connected to its outer side. A track link support module is engaged with the conveying track. The track link support module includes a conveying base plate, a lower contoured support seat, and a closed bottom shell. The lower contoured support seat and the closed bottom shell are both fixedly connected to the top of the conveying base plate. The lower contoured support seat, which matches the track link, is used for inserting the track link. A protruding end shell, an arc-shaped protruding part shell, a flat end shell, and a side recessed part shell move downwards to press the track link from above. After the lower contour-following support is clamped, the track link is completely in a closed space. The spraying component directly disperses and releases the magnetic powder liquid into different areas of the closed and isolated space and into the four holes of the track link. This helps to control the amount of magnetic powder liquid remaining on the outside of the finished track link and the contact time. However, the device fixes the track link through the lower contour-following support, which is only suitable for this type of track link. When the size of the track link varies, such as when the internal opening is small, it is not easy to stably position the track link. This makes the device limited, with poor flexibility in use and a small range of applications.

[0004] Therefore, we propose a loading and unloading device for machining track links to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a loading and unloading device for processing track links, so as to solve the problem that the device fixes the track links by means of a lower conforming bearing seat, which is only suitable for use with track links of that type. When the size of the track links varies, it is not convenient to stably position the track links, and the applicable range is small.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a loading and unloading device for processing track link sections, comprising a mounting frame, a support rod and a detection device, wherein a conveyor belt is installed on the inner side of the mounting frame and a robotic arm device is symmetrically installed at both ends of the outer side of the mounting frame;

[0007] Also includes:

[0008] A positioning component is provided on the top of the conveyor belt, a coating component is provided on one side of the top of the mounting frame, and the detection device is fixedly installed on the other side of the top of the mounting frame.

[0009] The positioning component includes a placement seat, a discharge push rod installed in the middle of the inner bottom surface of the placement seat, the placement seat fixedly connected to the outer surface of the conveyor belt, a placement plate slidably connected inside the placement seat, a positioning rod fixedly connected to the top of the placement plate, a first clamping plate symmetrically installed on one side of the top of the placement plate, a second clamping plate installed on the top of the placement plate, a guide rod symmetrically fixed to the inner bottom surface of the placement seat, and a rack fixedly connected to the bottom of the placement plate.

[0010] A lead screw is rotatably connected to the side wall of the placement seat. A gear is fixedly connected to the outside of the lead screw. An adjusting sleeve is sleeved on the outside of the lead screw. A connecting rod is fixedly connected to the top of the adjusting sleeve. The connecting rod is slidably connected to the placement plate. The top of the connecting rod is fixedly connected to the first clamping plate.

[0011] The top of the placement plate is rotatably connected to a guide wheel. Pull ropes are symmetrically fixed on both sides of the first clamping plate. The pull ropes pass around the guide wheel and are fixedly connected to a push block. An inner rod is symmetrically fixed on the inner side of the placement seat. The inner rod is slidably connected to the second clamping plate. An inclined block is symmetrically fixed on one side of the second clamping plate. The push block abuts against the inclined block.

[0012] The coating component includes a material tank, an electric push rod is fixedly installed on the inner top surface of the material tank, a connecting pipe is connected to the bottom of the material tank, a horizontal plate is connected to the bottom end of the telescopic part of the electric push rod, and a positioning frame is connected to the bottom of the horizontal plate.

[0013] Preferably, the placement seats are evenly distributed, the outer side of the placement plate is in contact with the inner wall of the placement seat, the positioning rod is located at the top center of the placement plate, and there are no fewer than two positioning rods.

[0014] By adopting the above technical solution, a positioning component is provided. Two sliding rods clamp the left and right sides of the track link, and two second clamping plates clamp the front and rear sides of the track link. This improves the positioning effect of the device on track links of different sizes and also improves the applicability of the device. At the same time, it does not need to completely jam the inner hole of the track link, which facilitates the subsequent coating operation of magnetic powder liquid.

[0015] Preferably, there are at least two guide rods, the placement plate is slidably connected to the guide rods, a spring is sleeved on the outer side of the guide rod, the top end of the spring is fixedly connected to the placement plate, and the bottom end of the spring is fixedly connected to the placement seat.

[0016] By adopting the above technical solution, after the positioning rod is positioned and placed in conjunction with the hole on the track link, the weight of the track link presses down on the placement plate, causing the placement plate to compress the spring and move down, which facilitates the subsequent clamping of the track link.

[0017] Preferably, the rack is centrally symmetrically arranged, a baffle is fixedly connected to the inner bottom surface of the placement seat, and one end of the lead screw is rotatably connected to the baffle.

[0018] By adopting the above technical solution, the baffle is used to assist the rotation of the lead screw.

[0019] Preferably, the placement plate has symmetrically formed sliding grooves inside, the connecting rod is located inside the sliding groove, a sliding rod is fixedly connected inside the sliding groove, the connecting rod is slidably connected to the sliding rod, and a second spring is fixedly connected inside the sliding groove, one end of the second spring being fixedly connected to the connecting rod.

[0020] By adopting the above technical solution, the lead screw rotates and drives the connecting rod to move. The connecting rod slides on the slide bar, and the connecting rod compresses the second spring. The connecting rod drives the slide bar to tighten towards the middle, so that the two slide bars clamp the left and right sides of the track link.

[0021] Preferably, the inner side of the placement seat is symmetrically provided with limiting grooves, the side of the pushing block away from the second clamping plate is fixedly connected to a limiting block, and a spring is fixedly connected inside the limiting groove.

[0022] By adopting the above technical solution, the sliding rod moves to drive the tension rope, the guide wheel guides the tension rope, so that the tension rope pulls the push block to move, the limit block moves in the limit groove, and the limit block compresses the spring three, which facilitates the limitation of the push block.

[0023] Preferably, the limiting block is slidably connected to the spring three, the limiting block is fixedly connected to the spring three, and the pushing block is located on both sides of the inner rod.

[0024] By adopting the above technical solution, the push block moves and squeezes the inclined surface of the inclined block. The inclined block drives the second clamping plate to slide on the inner rod, so that the two second clamping plates clamp the front and rear sides of the track link.

[0025] Preferably, the electric push rods are symmetrically arranged, with two electric push rods located on both sides of the connecting tube, the horizontal plate is fixedly connected to the positioning frame, and the positioning frame is in contact with the outer wall of the placement seat.

[0026] By adopting the above technical solution, when the placement seat moves to the bottom of the material box, the electric push rod drives the horizontal plate to descend, and the horizontal plate drives the positioning frame to descend, so that the positioning frame fits against the outer side of the placement seat.

[0027] Preferably, a pressure pump is installed inside the material box, and the outlet end of the pressure pump is connected to a connecting pipe. The end of the connecting pipe away from the pressure pump passes through the cross plate and is located inside the positioning frame.

[0028] By adopting the above technical solution, the pressure pump inside the material box pumps the magnetic powder liquid into the interior of the placement seat through the connecting pipe, which facilitates the magnetic powder liquid to cover the surface and holes of the chain link, thus improving the coating effect.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the positioning component is provided, the two slide bars clamp the left and right sides of the track link, and the two second clamping plates clamp the front and rear sides of the track link, which improves the positioning effect of the device on track links of different sizes and also improves the applicability of the device. At the same time, it does not need to completely jam the inner hole of the track link, which facilitates the subsequent coating operation of magnetic powder liquid.

[0030] 1. Equipped with a positioning component, the robotic arm places the track link on the placement plate. After positioning by the positioning rod and the holes on the track link, the weight of the track link presses down on the placement plate, causing the placement plate to compress the spring and move downwards. The guide rod guides the placement plate, which in turn moves the rack downwards. The rack drives the gear and lead screw to rotate, and the rotation of the lead screw moves the connecting rod. The connecting rod slides on the slide bar, compressing the spring. The connecting rod then causes the slide bar to tighten towards the center, clamping the two slide bars between the left and right sides of the track link. Simultaneously, the movement of the slide bar stretches the pull rope. The guide wheel guides the pull rope, causing the pull rope to pull the push block to move. The limiting block moves within the limiting groove, compressing the spring three to limit the pushing block. The pushing block moves and presses against the inclined surface of the inclined block. The inclined block drives the second clamping plate to slide on the inner rod, so that the two second clamping plates clamp the front and rear sides of the chain link. This improves the positioning effect of the device for chain links of different sizes and also improves the applicability of the device. At the same time, it does not need to completely jam the inner hole of the chain link, which facilitates the subsequent coating operation of magnetic powder liquid. This solves the problem that the device is only suitable for use with this type of chain link, and it is not easy to stably position the chain link when the size of the chain link is different, thus limiting its applicability.

[0031] 2. Equipped with a coating component, after the track link is positioned on the placement plate, the conveyor belt drives the placement seat to move intermittently until the placement seat moves below the material box. At this point, the electric push rod drives the horizontal plate to descend, and the horizontal plate drives the positioning frame to descend, so that the positioning frame fits against the outer side of the placement seat. At this time, the pressure pump inside the material box pumps the magnetic powder liquid into the interior of the placement seat through the connecting pipe, which facilitates the magnetic powder liquid to cover the surface and holes of the track link, improves the coating effect, and facilitates subsequent testing.

[0051] Example 1: As Figure 1-8 As shown, a positioning component 5 is provided. Two robotic arms 4 are used to load and unload the track links. The robotic arms 4 place the track links on the placement plate 52. After positioning by the positioning rod 53 and the holes on the track links, the track links press down on the placement plate 52 due to their weight. The placement plate 52 compresses the spring 57 and moves downward. The guide rod 56 guides the placement plate 52. The placement plate 52 drives the rack 58 to move downward.

[0053] A coating component 6 is provided on the top side of the mounting bracket 1. The coating component 6 includes a material box 61. An electric push rod 62 is fixedly installed on the inner top surface of the material box 61. A connecting pipe 63 is connected to the bottom of the material box 61. A horizontal plate 64 is connected to the bottom of the telescopic part of the electric push rod 62. A positioning frame 65 is connected to the bottom of the horizontal plate 64.

[0054] The electric push rods 62 are symmetrically arranged, with two electric push rods 62 located on both sides of the connecting tube 63. The horizontal plate 64 is fixedly connected to the positioning frame 65, and the positioning frame 65 is in contact with the outer wall of the placement seat 51.

[0055] A pressure pump is installed inside the material box 61. The outlet end of the pressure pump is connected to the connecting pipe 63. The end of the connecting pipe 63 away from the pressure pump passes through the horizontal plate 64 and is located inside the positioning frame 65.

[0056] Example 2: Figure 9-10 As shown, a coating component 6 is provided. After the track link is positioned on the placement plate 52, the conveyor belt 3 drives the placement seat 51 to move. The conveyor belt 3 moves intermittently until the placement seat 51 moves below the material box 61. At this time, the electric push rod 62 drives the horizontal plate 64 to descend, and the horizontal plate 64 drives the positioning frame 65 to descend, so that the positioning frame 65 is in contact with the outer side of the placement seat 51. At this time, the pressure pump inside the material box 61 pumps the magnetic powder liquid into the interior of the placement seat 51 through the connecting pipe 63, which makes it easier for the magnetic powder liquid to cover the surface and holes of the track link, improves the coating effect, and facilitates subsequent testing.

[0057] Working principle: When using this device, firstly, as... Figure 1-10 As shown, the loading and unloading of the track links are achieved by two robotic arms 4. The robotic arms 4 place the track links on the placement plate 52. After positioning by the positioning rod 53 and the hole on the track link, the track link presses down on the placement plate 52 due to its weight. The placement plate 52 compresses the spring 57 and moves down. The guide rod 56 guides the placement plate 52. The placement plate 52 drives the rack 58 to move down. The rack 58 drives the gear 510 and the lead screw 59 to rotate. The rotation of the lead screw 59 drives the connecting rod 513 to move. The connecting rod 513 slides on the slide rod 514. The connecting rod 513 compresses the spring 515. The connecting rod 513 drives the slide rod 514 to tighten towards the middle, so that the two slide rods 514 clamp the left and right sides of the track link.

[0058] Simultaneously, the sliding rod 514 moves to drive the tension rope 517, and the guide wheel 516 guides the tension rope 517, causing the tension rope 517 to pull the push block 519 to move. The limiting block 520 moves within the limiting groove 518, and the limiting block 520 compresses the spring 3 521 to facilitate limiting the push block 519. The push block 519 moves to press the inclined surface of the inclined block 523, and the inclined block 523 drives the second clamping plate 55 to slide on the inner rod 522, so that the two second clamping plates 55 clamp the front and rear sides of the track link.

[0059] After the track link is positioned on the placement plate 52, the conveyor belt 3 drives the placement seat 51 to move intermittently until the placement seat 51 moves below the material box 61. At this time, the electric push rod 62 drives the horizontal plate 64 to descend, and the horizontal plate 64 drives the positioning frame 65 to descend, so that the positioning frame 65 fits against the outside of the placement seat 51. At this time, the pressure pump inside the material box 61 pumps the magnetic powder liquid into the interior of the placement seat 51 through the connecting pipe 63, so that the magnetic powder liquid can cover the surface and holes of the track link, improving the coating effect. Then, the electric push rod 62 drives the horizontal plate 64 to rise, and the conveyor belt 3 continues to drive the placement seat 51 to move. When passing through the detection device 7, the detection device 7 detects the track link inside the placement seat 51.
