[0002] In the field of new energy vehicle manufacturing, the conveying of the longitudinal beam of the vehicle frame is a key link in the production process. The assembly and maintenance efficiency of the conveying device directly affects the production progress and cost. For traditional chain conveying devices for vehicle frame longitudinal beams, there are many inconveniences in the installation and disassembly of the support components. When installing the support components, due to the limitations of the device structure design, there is often a lack of convenient installation channels, resulting in a complex and cumbersome installation process. Multiple tools are required, consuming a large amount of time and manpower, seriously reducing the overall assembly efficiency of the device, and thus affecting the production rhythm of new energy vehicle manufacturing.

[0016] Among them, two dark grooves are symmetrically opened at the lower end of the central column. Two main clamping blocks are slidably connected in the two dark grooves through springs. The lower ends of the two main clamping blocks penetrate through the corresponding dark grooves and extend to the outside. A clamping groove for clamping the power rod is formed between the two main clamping blocks. The width of the clamping groove is greater than the cross-sectional diameter of the power rod. Inclined wall one is arranged on the opposite sides of the two main clamping blocks.

[0017] Preferably, auxiliary clamping blocks are arranged on both sides of the two main clamping blocks, and the lower ends of the auxiliary clamping blocks extend arc-shaped towards the middle of the clamping groove;

[0018] The distance between the lower ends of the auxiliary clamping blocks on the two main clamping blocks is less than the cross-sectional diameter of the power rod, and the distance between the lower end of the auxiliary clamping block and the opposite main clamping block is greater than the cross-sectional diameter of the power rod.

[0019] Preferably, two guide wheels one are arranged at both ends of the bottom plate, and the guide wheels one are all rollingly connected to the inner circumferential wall of the guide groove on the same side;

[0020] One guide wheel two is arranged at both ends of the support plate, and the guide wheel two is rollingly connected to the outer circumferential wall of the guide groove on the same side.

[0021] Preferably, a plurality of buffer grooves are evenly distributed on the bottom plate, and a plurality of buffer columns are evenly distributed on the support plate.

[0031] Compared with the prior art:

[0032] 1. During the installation of the support assembly of the present invention, by forming an installation opening on the side wall of the guiding track and providing a detachable baffle, great convenience is provided for the installation of the support assembly. During installation, only need to first remove the baffle, lift the assembled bottom plate and support plate, put the guide wheel into the guiding groove from the installation opening, and then through simple pressing and pushing operations, the preliminary positioning of the support assembly on the guiding track can be completed. Subsequently, the chain is used to drive the power rod to move, and the cooperation between the power rod and the inclined wall of the main clamping block can automatically make the power rod enter the clamping groove and be clamped. The entire installation process does not require complex operation steps and tools, greatly saving installation time and labor costs. This convenient and efficient installation method enables the chain conveyor device for transporting the longitudinal beam of the new energy vehicle frame to quickly complete the installation of the support assembly during assembly, improving the overall assembly efficiency of the device.

[0033] 2. When disassembling the support assembly of the present invention, also relying on the design of the installation opening, after removing the baffle, rotate the chain to drive the power rod to move the support assembly to the position of the installation opening. At this time, the elastic pressing action of the buffer member makes the guide wheel move out of the guiding groove from the installation opening, and at the same time, the central column slides upward. When the guide rod slides from the locking groove to the inside of the sinking groove and the lower end of the auxiliary clamping block is subjected to the spreading force of the power rod, the auxiliary clamping block can rotate on the main clamping block, enabling the power rod to be quickly released from the clamping groove, thereby realizing the quick disassembly of the support assembly. This flexible and fast disassembly method greatly facilitates the maintenance and replacement of the support assembly. When the support assembly fails or needs to be replaced with a support assembly of a different specification, there is no need to perform large-scale disassembly of the entire device, and only need to disassemble the support assembly according to simple steps, effectively reducing maintenance costs and time costs, and improving the reliability and maintainability of the device.

[0069] Embodiment Three

[0070] As Figures 4 - 12 shown, on the basis of Embodiment Two, in this embodiment, in order to lock the power rod 202 in the clamping groove formed between the two main clamping blocks 505, auxiliary clamping blocks 509 are arranged on both sides of the two main clamping blocks 505, and the lower ends of the auxiliary clamping blocks 509 arc towards the middle of the clamping groove;

[0071] the distance between the lower ends of the auxiliary clamping blocks 509 on the two main clamping blocks 505 is less than the cross-sectional diameter of the power rod 202, and the distance between the lower end of the auxiliary clamping block 509 and the opposite main clamping block 505 is greater than the cross-sectional diameter of the power rod 202.

[0072] Two guide wheels 507 are arranged at both ends of the bottom plate 501, and the guide wheels 507 are all rotatably connected to the inner circumferential wall of the same-side guide groove 401;

[0073] One guide wheel 508 is arranged at both ends of the support plate 502, and the guide wheel 508 is rotatably connected to the outer circumferential wall of the same-side guide groove 401.

[0074] A plurality of buffer grooves 5014 are evenly distributed on the bottom plate 501, and a plurality of buffer columns 5021 are evenly distributed on the support plate 502. The plurality of buffer columns 5021 are slidably inserted into the corresponding buffer grooves 5014. A buffer member 506 for buffering is provided between the buffer grooves 5014 and the buffer columns 5021. The buffer member 506 can be a spiral columnar spring.

[0075] The secondary clamping block 509 is rotatably connected to the main clamping block 505, and a guide rod 5091 is fixed above the secondary clamping block 509;

[0076] Vertical grooves 5032 are formed in the side wall of the dark groove 5031 along the length direction of the dark groove 5031. An arc groove 5033 is formed at the lower end of the vertical groove 5032. The center of the arc of the arc groove 5033 coincides with the rotation axis of the secondary clamping block 509. The guide rod 5091 slides in the vertical groove 5032 and the arc groove 5033;

[0077] A sunken groove 5012 is formed in the side wall of the through groove 5011, and a locking groove 5013 is provided at the lower end of the sunken groove 5012. The end of the guide rod 5091 extends into the sunken groove 5012.

[0078] On one side of the secondary clamping block 509 away from the clamping groove, an inclined wall two 5092 adapted to the shape of the inclined wall one 5051 is provided;

[0079] When the guide rod 5091 is inside the vertical groove 5032, the inclined wall two 5092 and the inclined wall one 5051 are in a coincident state.

[0080] As Figures 2 - 3 shown, in order to be able to install the first guide wheel 507 on the bottom plate 501 and the second guide wheel 508 on the support plate 502 in the guide groove 401, an installation opening 402 is formed in the side wall of the guiding track 4. A baffle 7 is slidably inserted through the installation opening 402 by a locking bolt 6. When installing the baffle 7, the baffle 7 is horizontally inserted to the installation opening 402, and then the threaded end of the locking bolt 6 penetrates through the installation opening 402 and the baffle 7 and meshes with the side wall of the guiding track 4. At this time, the baffle 7 can be fixed on the installation opening 402;

[0081] When the baffle 7 is removed, the installation opening 402 is in an open state;

[0082] When the locking bolt 6 fixes the baffle 7 on the installation opening 402, the installation opening 402 is in a closed state, and at the same time, the lower surface of the baffle 7 fits with the outer peripheral wall of the guide groove 401.

[0083] Ramps 403 are provided on both sides of the installation opening 402.

[0084] The process of installing the installation support assembly 5:

[0085] As Figure 3As shown, remove the baffle 7 on the mounting opening 402, then assemble the bottom plate 501 and the support plate 502 of the support assembly 5. Lift the assembled bottom plate 501 and support plate 502, and place the first guide wheel 507 on the bottom plate 501 and the second guide wheel 508 on the support plate 502 into the guide groove 401 through the mounting opening 402. At this time, the first guide wheel 507 abuts against the inner circumferential wall of the guide groove 401. Then press the support plate 502 to compress the buffer member 506, causing the second guide wheel 508 to move downward into the guide groove 401. In this state, push the support assembly 5 to one side so that the second guide wheel 508 is staggered with the mounting opening 402. After releasing the support plate 502, the buffer member 506 rebounds upward, causing the second guide wheel 508 to abut against the outer circumferential wall of the guide groove 401. At the same time, the central column 503 is inserted into the through groove 5011, the lower end of the main clamping block 505 extends between the two chains 201, and the guide rod 5091 is located at the intersection of the vertical groove 5032 and the arc groove 5033. The guide rod 5091 is also in the locking groove 5013 (the guide rod 5091 can be located at a non-lower end position in the locking groove 5013 to allow the buffering of the buffer member 506. If the longitudinal beam is placed on the support plate 502, the support plate 502 sinks, and the second guide wheel 508 can be separated from the outer circumferential wall of the guide groove 401).

[0086] As Figure 8 shown, the chain 201 drives the power rod 202 to move in the arrow direction. As the power rod 202 moves, the power rod 202 will abut against the inclined wall 5051 on the same side of the main clamping block 505. At this time, the power rod 202 will press against the inclined wall 5051. After the inclined wall 5051 is stressed, the main clamping block 505 slides upward (at this time, the guide rod 5091 on the auxiliary clamping block 509 slides upward along the vertical groove 5032). In this way, the power rod 202 will cross over from the bottom of the main clamping block 505 and enter the inside of the clamping groove. When the power rod 202 crosses over the main clamping block 505, the spring 504 presses the main clamping block 505 downward to reset. In this way, the two main clamping blocks 505 clamp the power rod 202, and at the same time, the lower end of the auxiliary clamping block 509 restricts the power rod 202 (using the state of the guide rod 5091 in the locking groove 5013 to prevent the auxiliary clamping block 509 from rotating on the main clamping block 505), so that it cannot escape from the clamping groove during operation.

[0087] Longitudinal beam of the conveying vehicle frame: When using this chain conveying device, start the motor 302. The output shaft of the motor 302 drives the runner 301 to rotate, drives the chain 201 to rotate, and further makes the power rod 202 operate. The power rod 202 enters the clamping groove of the main clamping block 505 of the support assembly 5, pushes the support assembly 5 to slide on the guide track 4, and at the same time locks the power rod 202 through the auxiliary clamping block 509 to ensure the stable operation of the support assembly 5. The support plate 502 supports the longitudinal beam of the vehicle frame to realize the conveying of the longitudinal beam of the vehicle frame.

[0088] Process of disassembling the support assembly 5:

[0089] Remove the baffle 7 from the mounting opening 402, rotate the chain 201, and make the power rod 202 drive the support assembly 5 to move towards the mounting opening 402. When the second guide wheel 508 on the support plate 502 moves to the position of the mounting opening 402, the buffer member 506 elastically presses the support plate 502 upwards, causing the second guide wheel 508 to move out of the guide groove 401 from the mounting opening 402. At the same time, the support plate 502 drives the central column 503 to slide upwards. During the upward sliding of the central column 503, its main clamping block 505 and the auxiliary clamping block 509 slide upwards synchronously relative to the power rod 202. After the guide rod 5091 slides from the locking groove 5013 into the internal sunken groove 5012, and when the lower end of the auxiliary clamping block 509 is subjected to the spreading force of the power rod 202, the guide rod 5091 can slide in the arc groove 5033. At this time, the auxiliary clamping block 509 rotates on the main clamping block 505, causing the lower end of the auxiliary clamping block 509 to open. In this way, the power rod 202 can be quickly released from the clamping groove, so that the support assembly 5 can be quickly disassembled.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
