DETAILED DESCRIPTION

[0024] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0025] like Figure 1 As shown, the assembly chassis line telescopic spreader includes a frame 1, with booms 2 at both ends of the frame 1, the bottom end of the boom 2 is connected to a support arm 3, the end of the support arm 3 is connected to a support 5, the support arm 3 is connected to a support beam 4, one end of the support beam 4 extends from the support arm 3, and the end of the support beam 4 is connected to a support block 6. The support beam 4 is installed on the support arm 3, the support arm 3 and the boom 2 are an integrated structure, and the boom 2 is connected to the frame 1 to form a spreader body. The support 5 is used to support the front end of the chassis, and the support block 6 is used to support the side skirt of the chassis to achieve the supporting effect of the front support and rear support of the chassis end. There are two supports 5 and two support blocks 6, which support the chassis at four points. The two sides of the chassis are fixed to the support arm 3 through connecting holes 7. The chassis has high stability during rotation or assembly processes. The support beam 4 can be extended and retracted on the support arm 3. During operation, according to the model of the vehicle to be put on the line, the support beam 4 is manually slid to a reasonable position and then the pin shaft 8 is used to fix the support beam 4 to complete the precise positioning of the support beam 4. It can be applied to the chassis support of models with side skirts of different lengths, meet the load-bearing and rotation of the models on the line, and improve the flexible production capacity of the chassis production line.

[0026] like Figure 4 As shown, a connection hole 7 is provided at the upper end of the support arm 3, a pin hole 9 is provided at the side of the support arm 3, a pin shaft 8 is connected to the support arm 3 and the support beam 4, and the connection holes 7 and the pin holes 9 are arranged at equal intervals. Multiple connection holes 7 are used to fix the two sides of the chassis, and the support beam 4 is provided with multiple holes for fixing the pin shaft 8. The support beam 4 and the support arm 3 are positioned and fixed by the pin shaft 8 and the pin hole 9. The pin shaft 8 is inserted into the pin hole 9 to fix the support beam 4 on the support arm 3. The provision of multiple pin holes 9 can conveniently adjust the extension distance of the support beam 4, thereby adjusting the support block 6 to an accurate support position, which can meet the production of side skirt models with different lengths.

[0027] like Figure 4As shown, a guide groove 14 is provided on the side of the support beam 4, and a guide plate 13 is provided on the inner side of the support arm 3, and the guide groove 14 and the guide plate 13 cooperate. The guide groove 14 is provided on the side of the support beam 4, and a limit plate is installed on the inner side of the support beam 4 to ensure that the sliding of the support beam 4 drives the support block 6 to move to the required accurate position. The guide plate 13 is fixedly connected to the inner side of the support arm 3 by bolts, and its structure is simple and easy to install and adjust. When the support beam 4 moves, the guide groove 14 moves along the guide plate 13 to guide the horizontal lateral movement of the support beam 4, which can ensure that the pin shaft 8 is accurately aligned.

[0028] like Figure 2 As shown, the support arm 3 and the support beam 4 are both arranged horizontally, and the support 5 and the support block 6 are in the same horizontal plane. The above structure is used to ensure that the supporting force of each support 5 and each support block 6 tends to be consistent, so that the chassis is more stable during support.

[0029] like Figure 4 As shown, a connecting plate 10 is provided at the end of the support beam 4, and the connecting plate 10 is provided with a waist-shaped hole 11, and two waist-shaped holes 11 are provided. The support block 6 is provided with a mounting hole 12, and four mounting holes 12 are provided. The support block 6 is connected to the support beam 4 through the connecting plate 10. By providing the waist-shaped hole 11, the support block 6 can be adjusted along the length direction of the waist-shaped hole 11 by a certain distance, so that the support block 6 is in an accurate position relative to the chassis, and the support block 6 can accurately position and support the chassis side skirt position; providing two waist-shaped holes 11 can improve the position accuracy of the support block 6 when installing, and providing multiple mounting holes 12 can improve the connection and fastening effect of the support block 6.

[0030] like Figure 3 As shown, protrusions 21 are provided at both ends of the top of the support block 6, and the top of the support 5 is a conical structure. The setting of the protrusions 21 forms a groove-shaped structure at the top of the support block 6, which has the function of limiting and preventing disengagement, and improves the stability of the chassis support. The conical part at the top of the support 5 can be easily inserted into the mounting hole 12 of the chassis.

[0031] like Figure 1 and Figure 5 As shown, a bearing seat 22 is provided at the bottom of the frame 1, a rotating shaft 15 is provided at the top of the boom 2, and both ends of the rotating shaft 15 cooperate with the bearing seat 22. A bracket 16 is provided at the upper end of the frame 1, and a cylinder 17 is movably connected to the bracket 16. The cylinder 17 includes a telescopic rod 18, and the end of the telescopic rod 18 is movably connected to the boom 2. The above structure realizes the rotation of the boom 2, and the telescopic rod 18 is driven by the cylinder 17 to pull the boom 2, so that the space between the two booms 2 can be opened or closed, which facilitates the chassis to enter the bottom of the frame 1. After the two booms 2 are closed, the support arm 3 and the support beam 4 are located below the chassis and are in a horizontal state, and the next step is to carry out the chassis support process.

[0032] like Figure 2As shown, the boom 2 is an arched structure, and the frame 1 is welded from square tubes. Designing the boom 2 as an arched structure provides a space for the chassis to avoid, making it easier for the chassis to enter and exit; the main body of the frame 1 is welded from square tubes, which is convenient for the installation of components and is not easily deformed. The position and flatness of the components installed on the frame 1 can be maintained for a long time, improving the reliability of the sling, and the square tube has a simple structure, which is conducive to reducing processing costs.

[0033] like Figure 1 As shown, a connecting seat 19 is provided at the end of the frame 1. The connecting seat 19 can fix the frame 1 to the production line track to realize the transfer of the chassis by the sling.

[0034] like Figure 1 As shown, a reinforcing rod 20 is connected between the rotating shaft 15 and the boom 2. The reinforcing rod 20 is used to improve the structural strength of the rotating shaft 15 and the bracket 16, and can resist the structural deformation of the boom 2 caused by the chassis mass, and ensure that the support arm 3 and the support beam 4 are in a horizontal position.

[0035] After the production model arrives at the chassis position, the production model needs to be manually confirmed and the position of the support block 6 is adjusted. The specific adjustment method is as follows: pull out the pin shaft 8, pull the support beam 4 horizontally from the support arm 3 to the corresponding position, and install the pin shaft 8 in the corresponding pin hole 9 under the limiting and guiding action of the guide plate 13 to complete the fixed positioning of the support beam 4. After the adjustment is completed, the support block 6 moves longitudinally to the appropriate load-bearing position of the current model, the front end of the chassis is supported by the support 5, and the side skirt part of the chassis is supported by the support block 6. After confirming that the chassis is stable, the load-bearing and production transportation of the chassis can be completed.

[0036] The telescopic hoist of the chassis line of the final assembly realizes the function of front support and rear support at the end of the chassis by supporting the chassis through the support 5 and the support block 6. The telescopic support beam 4 and the support block 6 adjustable on the connecting plate 10 are adopted to enable the hoist to accurately support the chassis. It has strong applicability and meets the production requirements of side skirt models with different lengths, and improves the flexible production capacity of the chassis line conveying equipment in the final assembly workshop. The support beam 4 is easy to move and fix, and is convenient for installation and distance adjustment. The hoist is reasonably designed and the chassis has high load-bearing reliability, which meets the load-bearing and transfer requirements of the body assembly.
