[0031] This embodiment provides a header assembly fixture designed to address the difficulty of testing the header transmission system after assembly, thereby improving safety during header assembly and increasing harvester manufacturing efficiency. See also... Figure 5 , Figure 6 , Figure 5 , Figure 6 These represent different states of the header assembly fixture during header adjustment. The header assembly fixture in this embodiment includes a support frame 1 for supporting the header, a lifting assembly 2 for adjusting the header height or lifting range, and an adjustment assembly 3 for adjusting the header transmission system. For details, see [link to details]. Figures 1-4The support frame 1 includes a bracket 11 and a base frame 12. The bracket 11 supports one end of the header, and the base frame 12 is horizontally positioned to facilitate the installation of the lifting assembly 2. The bracket 11 of the header is located on one side of the base frame 12 and is used to support and suspend the header in the header assembly fixture. The base frame 12 is illustrated with the header operation direction as the longitudinal direction. It includes a group of longitudinal beams 121 arranged in parallel, and a group of crossbeams 122 connecting the longitudinal beams 121. The lifting assembly 2 is mounted on the base frame 12 and slides on it, thereby adjusting the header assembly angle. The lifting assembly 2 includes a sliding bracket 21, a lifting bracket 22, and a hydraulic cylinder 23. During header assembly, the front end of the header is supported on the bracket 11, and the rear end of the header, which connects to the harvester body, is supported on the lifting bracket 22. The sliding bracket 21 is mounted on the base frame 12, connected to the longitudinal beam 121, and slides on the longitudinal beam 121. The lifting bracket 22 is mounted on the sliding bracket 21. One end of the hydraulic cylinder 23 is fixed to the crossbeam 122 on one side of the base frame 12, and the other end is connected to the sliding bracket 21, driving the sliding bracket 21 to slide on the longitudinal beam 121. As the sliding bracket 21 slides, the lifting bracket 22 is lifted, thereby adjusting the assembly angle of the header during assembly, simplifying the assembly process for operators and improving assembly convenience. The debugging component 3 is mounted on the lifting bracket 22. After the header assembly is completed, the header's transmission system is connected to the debugging component 3, allowing for testing of the reliability of the header's transmission system. This process avoids the original header testing process that required connection to the harvester body, saving manpower and improving header manufacturing efficiency.

[0032] Preferably, the longitudinal beams 121 and crossbeams 122 of the base frame 12 are interconnected, and the brackets 11 and hydraulic cylinders 23 are connected at opposite ends of the base frame 12, with the brackets 11 and base frame 12 set perpendicularly to each other. This ensures the cutter head is at a certain height from the ground, preventing damage to the separating device on the front of the cutter head during testing and adjustment. To allow the cutter head to move smoothly along the direction of the longitudinal beams 121, at least two sets of sliding supports 21 are provided on the base frame 12. Each set of sliding supports 21 is driven by a hydraulic cylinder 23, thereby improving the ease of processing the cutter head.

[0033] In a specific embodiment, the sliding bracket 21 includes a side plate 211 disposed on one side of the longitudinal beam 121 and a sliding groove 212 on the opposite side of the side plate 211 and connected to the side plate 211. The side plate 211 is connected to the sliding groove 212 and slides along the longitudinal beam 121 in the direction of the longitudinal beam 121. When the sliding bracket 21 slides toward the bracket 11, the lifting bracket 22 disposed on the sliding bracket 21 rises. The lifting bracket 22 is connected to the upper end of the sliding bracket 21. Specifically, when the side plate 211 is connected to the sliding groove 212, a slot 213 is provided above the connection point with the longitudinal beam 121, and the lifting bracket 22 is fixed in the slot 213. The lifting bracket 22 includes a first support arm 221a, a second support arm 221b, and a first suspension 223. The first support arm 221a and the second support arm 221b are disposed on both sides of the first suspension 223. One end of the first support arm 221a and the second support arm 221b are connected to the first suspension 223, and the other end is connected to the base frame 12. The first suspension 223 includes a first suspension beam 2231 connected to the sliding bracket 21 and a second suspension beam 2232 supporting the cutting table. A set of first connecting arms 2231a and second connecting arms 2231b are respectively disposed on the left and right sides of the first suspension beam 2231. One end of the first connecting arm 2231a is connected to one end of the second connecting arm 2231b. The side of the first connecting arm 2231a connected to the second connecting arm 2231b is connected to the slot 213 on the sliding bracket 21, and the other end of the first connecting arm 2231a is connected to the second suspension beam 2232. When the hydraulic cylinder 23 drives the sliding bracket 21 to move along the longitudinal beam 121, the first connecting arm 2231a and the second connecting arm 2231b drive the second suspension beam 2232 to rise or fall, and the first suspension 223 flips along the axis where the slot 213 is located, thereby realizing the lifting of the cutting table.

[0034] Preferably, to maintain synchronous movement of the sliding brackets 21 on the longitudinal beam 121, adjacent sliding brackets 21 are connected by connecting brackets 214 to maintain synchronous movement of the sliding brackets 21 on the base frame 12. One end of the hydraulic cylinder 23 is fixed to the base frame 12, and the other end of the hydraulic cylinder 23 is connected to the connecting bracket 214. A connecting seat 2141 is provided on the connecting bracket 214, and the hydraulic cylinder 23 is connected to the connecting seat 2141, so that the position of the hydraulic cylinder 23 is limited to ensure the safety of the cutting table assembly and testing process.

[0035] In a specific implementation, the debugging component 3 is mounted on and connected to the first suspension 223. Specifically, the debugging component 3 is positioned between the second suspension beams 2232. The debugging component 3 includes a first drive shaft 31 and a transmission gear set 32, with the first drive shaft 31 and the second suspension beams 2232 arranged horizontally. During the debugging of the cutter head, the first drive shaft 31 passes through and connects to the cutter head transmission system. The transmission gear sets 32 on both sides of the first drive shaft 31 drive the cutter head transmission system to rotate or connect to the power supply components. The rotation of the first drive shaft 31 drives the transmission system inside the cutter head to rotate, thereby testing whether the cutter head is properly assembled. If the cutter head transmission system is abnormal, the power source of the debugging component 3 can be cut off, and the cutter head transmission system can be directly readjusted. This mode is convenient and simple.

[0036] Preferably, to prevent movement during the assembly of the cutting table, the lifting assembly 2 is also provided with a locking part 23 to limit the position of the lifting assembly 2 on the base frame 12. Specifically, a plurality of locking holes 1211 are provided on the longitudinal beam 121 of the corresponding sliding bracket 21, and locking pins 231 are provided on the sliding bracket 21. When the sliding bracket 21 is slid to the corresponding position on the longitudinal beam 121, the locking pins 231 are inserted into the locking holes 1211 to fix the position of the sliding bracket 21 and adjust the height of the lifting assembly 2. Since the assembly posture of the cutting table needs to be constantly adjusted during the assembly process, the lifting assembly 2 slides a lot on the longitudinal beam 121, causing wear at the connection between the longitudinal beam 121 and the sliding bracket 21. Therefore, a reinforcing part 1212 is provided on the longitudinal beam 121 to make the longitudinal beam 121 wear-resistant, thereby extending the service life of the longitudinal beam 121. Meanwhile, since the crossbeams 122 and longitudinal beams 121 of the base frame 12 are made using a welding process, the longitudinal beams 121 can be replaced after they are worn out and become unusable.

[0037] In a further embodiment, steering wheels 13 are provided around the bottom of the support frame 1. During harvester assembly, the tooling position can be moved at any time, facilitating header transfer or assembly. This reduces labor costs during header transfer and improves production efficiency and safety. At least one set of adjustment components 3 is provided on the first suspension 223. The adjustment components 3 are mounted on the second suspension beam 2232. When multiple sets of adjustment components 3 are mounted on the second suspension beam 2232, they are arranged side-by-side. When the lifting component 2 is raised, the adjustment components 3 have a height difference on the second suspension beam 2232, preventing interference between the two sets of adjustment components 3.

[0038] This utility model provides a harvester header assembly fixture. By setting an adjustment component 3 on the lifting component 2, it changes the problems of complex header transfer and testing processes and high labor costs after the header assembly is completed. The lifting bracket 22 and sliding bracket 21 on the lifting component 2 cooperate to adjust the height of the fixture, which can meet the manufacturing processes of various types of headers. At the same time, this assembly fixture can improve the safety and reliability of the header production and assembly process, significantly reduce the cost of header manufacturing, save human resources, and significantly improve the header assembly efficiency.

[0039] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
