Description

Technical Field

[0001] This utility model relates to the field of rotary platform technology, and in particular to a conveying rotary platform for use on a production line. Background Technology

[0002] In automobile assembly lines, conveyor rotary pallets are key equipment, and existing pallets have the following technical problems:

[0003] Inconvenient unlocking method: In existing technologies, a single-sided unlocking pin pull method is usually used. This unlocking method is laborious, requiring workers to expend extra effort to pull out the pin to unlock it. After unlocking, the pin must be inserted back into the positioning hole to lock it. The process is cumbersome, greatly reducing production efficiency and affecting the production line rhythm.

[0004] The pallet structure and operation are limited: The pallet has two layers, with the lower layer running on the conveyor line and the upper layer providing fixtures to position workpieces and achieve precise assembly. During assembly, the pallet needs to be rotated frequently for ease of operation. However, currently, pallet locking relies on a downward pin, and unlocking requires pulling out the pin, rotating to the designated position, and then repositioning the pin. This operation is complex and cannot meet the requirements for efficient assembly. Furthermore, single-sided unlocking restricts the collaborative work of workers on both sides, further hindering the improvement of production efficiency. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a conveyor rotary platform for production lines.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A conveyor rotary platform for a production line includes an upper pallet and a lower pallet, wherein the upper pallet is rotatably connected to the lower pallet, and the lower pallet is provided with a locking mechanism for locking the upper pallet. Both the upper and lower pallets are provided with unlocking mechanisms for quick unlocking of the upper pallet by pressing.

[0008] The locking mechanism is further configured as follows: the locking mechanism includes a locking seat mounted on the lower tray, the upper surface of the locking seat is vertically provided with a first sliding groove, a locking pin is slidably disposed in the first sliding groove, a locking spring in a compressed state is disposed between the locking pin and the bottom of the first sliding groove, and a locking hole is provided on the upper tray; the two sides of the locking seat are symmetrically provided with first limiting grooves communicating with the first sliding groove inside, the first limiting grooves are vertically disposed, an unlocking rod is horizontally disposed on the locking pin, the two ends of the unlocking rod pass through the two first limiting grooves respectively and extend to the outside, and slide vertically with the two first limiting grooves.

[0009] The unlocking mechanism is further configured to include four sets of pressing components arranged in a rectangular array and two sets of unlocking components located on both sides of the unlocking mechanism.

[0010] The pressing assembly is further configured as follows: the pressing assembly includes a mounting base mounted on an upper tray, the mounting base having a through hole, and the through hole being convex in shape; the upper tray having a clearance hole whose projection on the horizontal plane completely coincides with the large hole of the through hole; a pressing rod that is slidably disposed in the through hole and completely abuts against the inner wall; the top end of the pressing rod extending upward to the outside and fixed with a pressing handle; and a return spring that winds around the pressing rod is disposed between the lower surface of the pressing handle and the upper surface of the mounting base.

[0011] The unlocking assembly is further configured as follows: the unlocking component includes a spring pin and a linkage rod. The spring pin includes a spring seat, a second groove is vertically formed on the upper surface of the spring seat, a pin body is slidably arranged in the second groove, a first spring in a compressed state is arranged on the lower surface of the pin body, and second limiting grooves communicating with the second groove inside the spring seat are symmetrically formed on both sides of the spring seat. The second limiting grooves are vertically arranged, and a limiting rod is horizontally arranged on the pin body. The two ends of the limiting rod pass through the two second limiting grooves respectively and slide vertically.

[0012] Further configuration: the upper surface of the spring seat is provided with a slot, the slot and the two second limiting slots are arranged in a cross shape in the horizontal direction; the upper surface of the pin is provided with an arc-shaped groove that matches the linkage rod, the linkage rod is installed in the arc-shaped groove and the slot, and slides vertically with the slot, one end of the linkage rod passes through the two second limiting slots and extends to the top of the unlocking rod, and the other end extends to the bottom of the pressing rod and is provided with a pressure block.

[0013] The linkage rod is further configured such that the part located in the slot is designed with a groove, the groove surface of which abuts against the inner wall of the slot to limit the linkage rod in the left and right directions.

[0014] The upper tray is further configured to be rotatably connected to the lower tray via a cross roller bearing.

[0015] The upper tray is further configured such that multiple support bearings are arranged in a uniform circumferential array at the midpoint between the upper and lower trays to support the upper tray.

[0016] The upper tray is further configured to have four locking holes, which are evenly arranged around the circumference of the tray.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] 1. The press-type unlocking mechanism allows workers to quickly unlock the upper tray by simply pressing the handles on the two sets of pressing components. Unlike the traditional pin-pulling method, there is no need to exert extra force to pull out the pin and then insert it back into the positioning hole to lock it, which effectively improves production efficiency and reduces the workload of workers.

[0019] 2. Automatic locking: After the upper tray rotates to the target position, release the pressing handle. The return spring extends and drives the pressing rod and pressing handle to return to their original positions. The linkage rod moves upward accordingly. Under the elastic force of the locking spring, the unlocking rod drives the locking pin to move upward and re-insert into the locking hole, realizing automatic locking. No additional manual locking operation is required, which further improves the convenience of operation and the efficiency of assembly work.

[0020] In summary, this utility model, through the convenience of unlocking and locking operations, enables the upper tray to rotate and position more quickly, reduces the assembly time wasted due to the cumbersome unlocking and locking process, improves the rhythm and overall efficiency of the production line, and helps to increase the production capacity of the automobile assembly line.

[0021] This device overcomes the limitations of traditional single-sided unlocking, allowing workers on both sides to collaborate more easily. During assembly, after one worker completes the assembly at one station, the other worker can quickly unlock the pallet and rotate it to the next station, improving the continuity and efficiency of assembly operations and facilitating efficient collaboration and balanced production on the production line.

[0033] Example

[0034] Reference Figures 1-6This utility model discloses a conveying rotary platform for production lines, comprising an upper pallet 1 and a lower pallet 2. The upper pallet 1 is rotatably connected to the lower pallet 2 at the middle position via crossed roller bearings 3. Due to the high precision and high rigidity of the crossed roller bearings 3, the upper pallet 1 can maintain good balance and stability during rotation. Multiple support bearings 4 are arranged in a uniform circumferential array around the crossed roller bearings 3 at the middle position between the upper pallet 1 and the lower pallet 2. Specifically, the multiple support bearings 4 are bolted to the lower pallet 2, and their tops support the upper pallet 1. The even distribution of the multiple support bearings 4 evenly distributes the weight of the upper pallet 1 and the workpiece onto the lower pallet 2, avoiding excessive local stress, deformation, or damage caused by concentrated load at a single point. This effectively improves the load-bearing capacity and stability of the entire rotary platform, ensuring stable operation even when carrying heavy workpieces.

[0035] A locking mechanism 5 is provided on the lower tray 2 to lock and position the upper tray 1. Unlocking mechanisms are provided on both the upper tray 1 and the lower tray 2. The unlocking mechanisms are used to quickly unlock the upper tray 1 by pressing.

[0036] Specifically, the locking mechanism 5 includes a locking seat 6 mounted on the lower tray 2 by bolts. The upper surface of the locking seat 6 has a first groove 7 vertically formed. A locking pin 8 is slidably arranged in the first groove 7. A locking spring 9 in a compressed state is vertically arranged between the locking pin 8 and the bottom of the first groove 7. The upper tray 1 has four locking holes 10, which are evenly arranged circumferentially. On both sides of the locking seat 6, there are first limiting grooves 11 that communicate with the first groove 7 inside. The first limiting grooves 11 are vertically arranged. The same unlocking rod 12 is horizontally arranged on the locking pin 8. The two ends of the unlocking rod 12 pass through the two first limiting grooves 11 and extend to the outside. The unlocking rod 12 is vertically slidably engaged with the two first limiting grooves 11.

[0037] Furthermore, the unlocking mechanism includes a pressing component 13 and an unlocking component 14. The pressing component 13 is provided in four sets, and the four sets of pressing components 13 are evenly arranged in a rectangular array. The unlocking component 14 is provided in two sets, and the two sets of unlocking components 14 are located on both sides of the unlocking mechanism.

[0038] Specifically, the pressing assembly 13 includes a mounting base 15 mounted on the upper tray 1. The top of the mounting base 15 has a through hole 16, which is convex in shape. The upper tray 1 has a clearance hole 17, which is completely superimposed on the large hole of the through hole 16 on the horizontal plane. A pressing rod 18 is slidably disposed in the through hole 16 and is completely in contact with the inner wall. The top of the pressing rod 18 extends upward to the outside and is fixed with a pressing handle 19. A return spring 20 is disposed between the lower surface of the pressing handle 19 and the upper surface of the mounting base 15, and the return spring 20 is disposed around the pressing rod 18.

[0039] The unlocking component 14 includes a spring pin 21 and a linkage rod 22. The spring pin 21 includes a spring seat 23. A second groove 24 is vertically formed on the upper surface of the spring seat 23. A pin 25 is slidably arranged in the second groove 24. A first spring 26 in a compressed state is vertically arranged between the pin 25 and the second groove 24. A second limiting groove 27 communicating with the second groove 24 is symmetrically formed on both sides of the spring seat 23. The second limiting groove 27 is vertically arranged. The same limiting rod 28 is horizontally arranged on the pin 25. Two limiting rods are respectively inserted through the two ends of the limiting rod 28 and slide vertically with the second limiting groove 27.

[0040] A slot 29 is vertically formed on the upper surface of the spring seat 23, and the slot 29 and the two second limiting slots 27 are arranged in a cross shape in the horizontal direction.

[0041] An arc-shaped groove 30 adapted to the linkage rod 22 is provided on the upper surface of the pin 25. The linkage rod 22 is installed in the arc-shaped groove 30 and the straight groove 29, and slides vertically with the straight groove 29. One end of the linkage rod 22 passes through two second limiting grooves 27 and extends to the top of the unlocking rod 12. The other end of the linkage rod 22 extends to the bottom of the pressing rod 18 and is provided with a pressure block 31.

[0042] In another embodiment, the portion of the linkage rod 22 located in the slot 29 is designed with a groove 32. The groove surface of the groove 32 abuts and fits against the inner wall of the slot 29, thereby limiting the linkage rod 22 in the left and right directions. That is, when the linkage rod 22 tends to move left and right, the groove walls on the left and right sides of the groove 32 will abut against the spring seat 23, thereby restricting the left and right movement of the linkage rod 22.

[0043] The working principle and beneficial effects of this utility model are as follows:

[0044] Under normal conditions, the locking pin 8 is inserted into the locking hole 10 to lock and position the upper tray 1. When unlocking is required, the operator presses the pressing handle 19 on two sets of pressing components 13. The pressing handle 19 moves downward. Since the return spring 20 is wound around the pressing rod 18 and located between the lower surface of the pressing handle 19 and the upper surface of the mounting base 15, the return spring 20 is compressed when the pressing handle 19 is pressed down.

[0045] Pressing handle 19 drives pressing rod 18 to press down on the pressure block 31 on linkage rod 22, thereby driving linkage rod 22 to move downward along slot 29. During this process, linkage rod 22 presses down on unlocking rod 12 located below it. Unlocking rod 12 overcomes the elastic force of locking spring 9, thereby driving locking pin 8 to move downward, so that the top of locking pin 8 disengages from locking hole 10 of upper tray 1, thereby completing the unlocking operation and realizing the rotation of upper tray 1. After upper tray 1 rotates, the operator releases pressing handle 19. At this time, the return spring 20 begins to extend under its own elastic force, driving the pressing rod 18 and the pressing handle 19 to return to their original positions. After the linkage rod 22 loses the downward pressure of the pressing rod 18, it moves upward in the slot 29. At the same time, after the unlocking rod 12 loses the downward pressure of the linkage rod 22, it drives the locking pin 8 to move upward under the elastic force of the locking spring 9. After the upper tray 1 is rotated 190°, the top of the locking pin 8 will re-insert into the corresponding locking hole 10 of the upper tray 1, completing the automatic locking and positioning of the upper tray 1, thereby ensuring the stability and safety of the upper tray 1 in the new position and providing a reliable support platform for subsequent assembly operations.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
