Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a harvester track assembly fixture, the structure of which is as follows: Figure 1 and Figure 2As shown, the system includes a platform 100, a support frame 200, a mobile trolley 300, and a lifting unit 400. The platform 100 has a receiving groove 110 with an open top. The support frame 200 is fixedly installed in the receiving groove 110. The mobile trolley 300 is used to support the chassis 1 and can move onto the support frame 200 so that all the wheels on both sides of the chassis 1 are suspended. The lifting unit 400 is located below the receiving groove 110, and its lifting part is used to support the assembled track 2 and drive the chassis 1 after the track 2 is assembled to move up and down so that the chassis 1 is separated from the mobile trolley 300 or the bottom surface of the track 2 is flush with the top surface of the platform 100.

[0028] In use, the chassis 1 is placed on the mobile trolley 300, which then moves onto the support frame 200, thus suspending all the wheels on both sides of the chassis 1. Production personnel then attach the tracks 2 one by one to each wheel, completing the track assembly. Once the tracks 2 on both sides are assembled, the lifting unit 400 moves upward to support the assembled tracks 2. The lifting unit 400 continues to move upward, driving the chassis 1 with the assembled tracks 2 upward, allowing the chassis 1 to move away from the mobile trolley. 300, the mobile trolley 300 is moved off the supporting frame 200 to facilitate the mobile trolley 300 carrying the next frame 1. At this time, the lifting part of the lifting unit 400 moves downward, thereby driving the frame 1 after the track 2 is assembled to move downward, so that the bottom surface of the track 2 is flush with the top surface of the platform 100. The track 2 moves along the lifting part of the lifting unit 400 and reaches the platform 100. The harvester track assembly fixture can lift the entire frame 1, so that each wheel can be in a suspended state. It is suitable for use when assembling the track 2.

[0029] In other embodiments, the pedestal 100 can be directly selected from the foundation, and the receiving groove 110 is a foundation pit directly opened on the foundation.

The bottom surfaces of the two rails 220 are fixedly connected to the top of the support frame 210, and the top surfaces of the two rails 220 are flush with the surface of the pedestal 100. The mobile trolley 300 can move onto the two rails 220. The movement of the mobile trolley 300 can be guided by the two rails 220. When the mobile trolley 300 moves onto the two rails 220, due to the presence of the receiving groove 110, the wheels on both sides of the frame 1 can be suspended in the air.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4 The mobile trolley 300 includes two base rods 310, two rows of rollers 320, and two first support seats 330. The two base rods 310 are horizontally arranged and parallel to each other. The two rows of rollers 320 correspond one-to-one with the two base rods 310. Each roller 320 in each row is rotatably connected to the base rod 310 via an axle. The two rows of rollers 320 are used to travel one-to-one along the two tracks 220. The two first support seats 330 are spaced apart along the length direction of the two base rods 310. The bottom of each of the two first support seats 330 is fixedly connected to the two base rods 310. The tops of the two first support seats 330 are respectively used to support the two ends of the frame 1. The two ends of the frame 1 are placed on the two first support seats 330 respectively. The two first support seats 330 can support the frame 1. Then the two rows of rollers 320 of the mobile trolley 300 are moved to the two tracks 220 respectively. After traveling along the two base rods 310 to the preset position, the track 2 is then assembled.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 4 The frame 1 has a first slot 11 with a V-shaped structure at both ends, the width of which gradually increases from top to bottom. The upper end of the first support 330 has a first plug-in 331 with a V-shaped structure. The first plug-in 331 is used to be inserted into the first slot 11, thereby longitudinally limiting the frame 1 and preventing the frame 1 from moving longitudinally.

[0033] As a preferred embodiment, please refer to Figure 3 and Figure 4The first support 330 has a first slot 332 on its top. The first slot 332 is located on the top of the first plug-in 331. When the first plug-in 331 is inserted into the first slot 11, the end of the frame 1 slides into the first slot 332, thereby limiting the frame 1 laterally and preventing the frame 1 from moving laterally.

[0034] As a preferred embodiment, please refer to Figure 2 There are two lifting units 400, which are located on both sides of the support frame 200. The two lifting units 400 are used to support the two assembled tracks 2 one by one. The two lifting units 400 can support the two tracks 2 respectively. When the two lifting units 400 drive the two tracks 2 to move up and down synchronously, the frame 1 can be driven to move up and down.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 5 The lifting unit 400 includes a first base frame 410, a first top plate 420, a first movable outer frame 430, a first movable inner frame 440, and a first telescopic drive component. The first base frame 410 and the first top plate 420 are horizontally arranged from bottom to top, and the first base frame 410 is fixedly connected to the platform 100. The first top plate 420 is used to support the assembled track 2. The first movable outer frame 430 and the first movable inner frame 440 are arranged to cross each other, and the intersection of the first movable outer frame 430 and the first movable inner frame 440 is rotatably connected via a pivot. The high end of the first movable outer frame 430 is rotatably connected to the first top plate 420 via a pivot, and the low end of the first movable outer frame 430 is slidably connected to the first base frame 410 via a pivot, and can slide horizontally along the length direction of the first base frame 410.

The first bottom frame 410 is rotatably connected, and the high end of the first movable inner frame 440 is slidably connected to the first top plate 420 via a pivot, and can slide horizontally along the length direction of the first top plate 420. The telescopic end of the first telescopic drive member is connected to the low end of the first movable outer frame 430, and is used to drive the low end of the first movable outer frame 430 to slide horizontally back and forth along the length direction of the first bottom frame 410. By operating the first telescopic drive member, the first telescopic drive member can drive the low end of the first movable outer frame 430 to slide horizontally back and forth along the length direction of the first bottom frame 410, thereby driving the high end of the first movable inner frame 440 to slide horizontally back and forth along the length direction of the first top plate 420, so that the distance between the low end of the first movable outer frame 430 and the high end of the first movable inner frame 440 increases or decreases, thereby realizing the lifting and lowering of the first top plate 420.

[0036] As a preferred embodiment, please refer to Figure 2 The harvester track assembly fixture further includes a lifting unit 500, which is disposed in the receiving groove 110 and located between the two tracks 220. It is used to support the mobile trolley 300 and drive the mobile trolley 300 to move up and down so that the mobile trolley 300 leaves or arrives on the support frame 200. When the mobile trolley 300 moves onto the support frame 200, the lifting unit 500 drives the mobile trolley 300 to move upward so that the mobile trolley 300 leaves the support frame 200, thereby lifting the vehicle frame 1, improving the suspension effect of each wheel, and making it easier for production personnel to wrap the tracks 2 around each wheel.

[0037] As a preferred embodiment, please refer to Figure 6The lifting unit 500 includes a second bottom frame 510, a second top plate 520, a second movable outer frame 530, a second movable inner frame 540, two second support seats 550, and a second telescopic drive component. The second bottom frame 510 and the second top plate 520 are horizontally arranged from bottom to top, and the second bottom frame 510 is fixedly connected to the platform 100. The second movable outer frame 530 and the second movable inner frame 540 are arranged intersecting each other, and the intersection of the second movable outer frame 530 and the second movable inner frame 540 is rotatably connected via a pivot. The high end of the second movable outer frame 530 is rotatably connected to the second top plate 520 via a pivot, and the low end of the second movable outer frame 530 is slidably connected to the second bottom frame 510 via a pivot, and can slide horizontally along the length direction of the second bottom frame 510. The low end of the second movable inner frame 540 is rotatably connected to the second bottom frame 510 via a pivot, and the high end of the second movable inner frame 540 is slidably connected to the second top plate 520 via a pivot, and can slide horizontally along the length direction of the second bottom frame 510. The plate 520 slides horizontally along its length. Two second support seats 550 are spaced apart along the length of the second top plate 520, and the bottoms of the two second support seats 550 are fixedly connected to the second top plate 520. The tops of the two second support seats 550 are respectively used to support the two ends of the mobile trolley 300. The telescopic end of the second telescopic drive member is connected to the lower end of the second movable outer frame 530, and is used to drive the lower end of the second movable outer frame 530 to slide horizontally back and forth along the length of the second bottom frame 510. By operating the second telescopic drive member, the second telescopic drive member can drive the lower end of the second movable outer frame 530 to slide horizontally back and forth along the length of the second bottom frame 510, thereby driving the upper end of the second movable inner frame 540 to slide horizontally back and forth along the length of the second top plate 520, so that the distance between the lower end of the second movable outer frame 530 and the upper end of the second movable inner frame 540 increases or decreases, thereby realizing the lifting and lowering of the second top plate 520.

[0038] As a preferred embodiment, please refer to Figure 4 and Figure 6 The first support 330 has a second slot 333 with a V-shaped structure whose opening width gradually increases from top to bottom. The upper end of the second support 550 has a second plug-in 551 with a V-shaped structure. The second plug-in 551 is used to be inserted into the second slot 333, thereby longitudinally limiting the mobile trolley 300 and preventing the mobile trolley 300 from moving longitudinally.

[0039] As a preferred embodiment, please refer to Figure 4 and Figure 6The second support 550 has a second slot 552 on its top. The second slot 552 is located on the top of the second plug-in 551. When the second plug-in 551 is inserted into the second slot 333, the first support 330 slides into the second slot 552, thereby limiting the lateral movement of the mobile trolley 300 and preventing the mobile trolley 300 from moving laterally.

[0040] As a preferred embodiment, please refer to Figure 2 and Figure 5 The harvester track assembly fixture also includes a clamping unit 600, which is disposed on the lifting unit 500 and is used to clamp or loosen the frame 1. When the moving trolley 300 moves onto the bearing frame 200, the clamping unit 600 can clamp the frame 1, thereby preventing the frame 1 from moving in the vertical direction when assembling the track 2.

[0041] As a preferred embodiment, please refer to Figure 2 and Figure 5The clamping unit 600 is located between the two second bearing seats 550. The clamping unit 600 includes a base 610, two clamping members 620, and two third telescopic drive members 630. The base 610 is fixedly connected to the top surface of the second top plate 520. The lower ends of the two clamping members 620 are rotatably connected to the inner sides of the two second bearing seats 550 via pins. The fixed ends of the two third telescopic drive members 630 are rotatably connected to the base 610 via pins. The telescopic ends of the two third telescopic drive members 630 are rotatably connected to the middle parts of the two clamping members 620 via pins. This is used to drive the two clamping members 620 to reciprocate synchronously around their lower pins, so that the upper ends of the two clamping members 620 simultaneously clamp or release the two ends of the frame 1. When the moving trolley 300 moves onto the bearing frame 200, by operating the two third telescopic drive members 630, the two third... The telescopic drive 630 extends, driving the two clamping members 620 to reciprocate synchronously around their lower pins. This allows the upper ends of the two clamping members 620 to simultaneously clamp the two ends of the frame 1. After the tracks 2 on both sides are assembled, by manipulating the two third telescopic drive 630s, the telescopic ends of the two third telescopic drive 630s retract, driving the two clamping members 620 to reciprocate synchronously around their lower pins. This allows the upper ends of the two clamping members 620 to simultaneously release the two ends of the frame 1. Since the first support seat 330 of the mobile trolley 300 has a V-shaped second slot 333, when the upper ends of the two clamping members 620 simultaneously release the two ends of the frame 1, the upper ends of the two clamping members 620 retract between the two first support seats 330, so that the movement of the mobile trolley 300 from the support frame 200 is not disturbed by the upper ends of the two clamping members 620.

[0042] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below:

[0043] In use, the frame 1 is placed on top of the two first support seats 330 of the mobile trolley 300. The two rows of rollers 320 of the mobile trolley 300 move to the two tracks 220 of the support frame 200. By operating the two third telescopic drive members 630, the telescopic ends of the two third telescopic drive members 630 extend, which can drive the two clamping members 620 to rotate synchronously around the pins at their lower ends. This allows the upper ends of the two clamping members 620 to synchronously press against both ends of the frame 1. Then, by operating the second telescopic drive member, the second telescopic drive member can drive the lower end of the second movable outer frame 530 to slide horizontally along the length direction of the second bottom frame 510, thereby enabling the frame 1 to move horizontally. The high end of the second movable inner frame 540 slides horizontally along the length of the second top plate 520, increasing the distance between the low end of the second movable outer frame 530 and the high end of the second movable inner frame 540. This allows the second top plate 520 to rise, lifting the mobile trolley 300 and thus the frame 1, improving the suspension effect of each wheel. This makes it easier for production personnel to attach the tracks 2 one by one to each wheel, completing the assembly of the tracks 2. After the tracks 2 on both sides are assembled, the second telescopic drive component is operated. The second telescopic drive component can drive the low end of the second movable outer frame 530 to slide horizontally along the length of the second bottom frame 510, thereby driving the second movable inner frame 540 to rise. The high end of frame 540 slides horizontally along the length of the second top plate 520, reducing the distance between the low end of the second movable outer frame 530 and the high end of the second movable inner frame 540, thereby lowering the second top plate 520 and allowing the moving trolley 300 to reach the supporting frame 200. Then, by manipulating the two third telescopic drive members 630, the telescopic ends of the two third telescopic drive members 630 retract, which can drive the two clamping members 620 to rotate synchronously around their lower pins, thereby allowing the upper ends of the two clamping members 620 to simultaneously release the two ends of the frame 1. By manipulating the first telescopic drive member, the first telescopic drive member can drive the low end of the first movable outer frame 430 along the length of the second top plate 520. The first bottom frame 410 slides horizontally along its length, thereby causing the high end of the first movable inner frame 440 to slide horizontally along the length of the first top plate 420. This increases the distance between the low end of the first movable outer frame 430 and the high end of the first movable inner frame 440, allowing the first top plate 420 to rise. The two first top plates 420 support two tracks 2. As the first top plates 420 continue to rise, they drive the chassis 1, after the tracks 2 are assembled, to move upward, causing the chassis 1 to leave the mobile trolley 300 and remove the mobile trolley 300 from the support frame 200, making it easier for the mobile trolley 300 to support the next chassis 1. At this time, by manipulating the first telescopic drive component...The first telescopic drive component can drive the lower end of the first movable outer frame 430 to slide horizontally along the length direction of the first bottom frame 410, thereby causing the upper end of the first movable inner frame 440 to slide horizontally along the length direction of the first top plate 420. This reduces the distance between the lower end of the first movable outer frame 430 and the upper end of the first movable inner frame 440, thus lowering the first top plate 420. This allows the chassis 1, after the tracks 2 are assembled, to move downwards, making the bottom surface of the tracks 2 flush with the top surface of the platform 100. The tracks 2 move along the first top plate 420 and reach the platform 100. Using this harvester track assembly fixture, the entire chassis 1 can be lifted, allowing each wheel to be suspended in the air. It is suitable for use when assembling the tracks 2.

[0044] The harvester track assembly fixture provided by this utility model has the following beneficial effects:

[0045] (1) After the mobile trolley 300 moves onto the support frame 200, the lifting unit 500 drives the mobile trolley 300 to move upward, so that the mobile trolley 300 leaves the support frame 200, and can lift the mobile trolley 300, thereby lifting the frame 1, improving the suspension effect of each wheel, and making it easier for production personnel to wrap the track 2 around each wheel;

[0046] (2) After the tracks 2 on both sides are assembled, the lifting part of the lifting unit 400 moves upward and carries the assembled track 2. The lifting part of the lifting unit 400 continues to move upward, thereby driving the frame 1 after the track 2 is assembled to move upward, so that the frame 1 leaves the mobile trolley 300 and moves the mobile trolley 300 off the support frame 200, so that the mobile trolley 300 can carry the next frame 1.

[0047] (3) The harvester track assembly fixture can lift the entire frame 1 so that each wheel can be suspended in the air, which is suitable for use when assembling the track 2.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
