Description

Technical Field

[0001] The utility model relates to the field of lifting equipment for multi-layer conveyor lines, in particular to a lifting rotating machine. Background Art

[0002] In modern industrial automation production, multi-layer conveyor lines are widely used due to their efficient space utilization and flexible production processes. However, in order to meet different process flows and production requirements, materials often need to be rotated on multi-layer conveyor lines to facilitate material handling and direction adjustment. This rotation operation is particularly important in a compact production workshop. For example, when transferring materials from one conveyor line to another, the direction and angle of the materials must be precisely controlled. Without proper rotation equipment, materials may pile up, jam, and other problems, seriously affecting the continuity and efficiency of the production line. For example, on the assembly line of electronic products, the welding of components requires a specific orientation. The components must maintain an accurate direction during welding to ensure the correctness and firmness of the welding points. If the position of the components is inaccurate, the welding quality will be affected, resulting in an increase in the defective rate and a decrease in production efficiency. In addition, some complex processing and assembly processes require multi-angle operations on materials. Especially for products with high precision and complex structures, the angle of the material needs to be adjusted many times during the manufacturing process. For example, in automated production such as automobile manufacturing and home appliance manufacturing, some components need to be automatically processed and assembled at multiple different angles. Failure to accurately adjust the material angle may result in automated assembly errors, affecting product performance and quality.

[0003] However, most of the existing methods are to rotate the material manually or by building a robot outside the conveyor line. These methods obviously have some problems. For example, manually adjusting the direction of the material requires a lot of labor, which not only increases the labor cost, but also may cause human errors, affecting production efficiency and product quality. In some high-intensity and long-term working environments, workers are prone to fatigue, which further increases the probability of errors. Building a robot outside the conveyor line requires additional space, which is particularly inconvenient in a compact production workshop. The design of the multi-layer conveyor line itself is to save space. If the rotation operation requires additional space, it violates this original intention. In addition, the cost of the robot is high, and the operation and programming are relatively complicated. Especially for robots that require high-precision operation, the purchase and maintenance costs are expensive. Professional technicians are required for maintenance and management. If the operation is improper, it may cause equipment failure, further affecting the operating stability and production efficiency of the production line. Obviously, small and medium-sized enterprises may find it difficult to bear these additional costs, limiting their ability to automate transformation and improve production efficiency.

[0004] Therefore, how to achieve efficient and accurate rotation operations on materials in the limited space of multi-layer conveyor lines is an urgent problem to be solved. Utility Model Content

The tooling positioning assembly 5 includes a first tooling positioning plate 51 respectively arranged in two of the oppositely arranged sliding grooves 42 and a second tooling positioning plate 52 respectively arranged in the other two oppositely arranged sliding grooves 42, the two first tooling positioning plates 51 and the two second tooling positioning plates 52 can slide toward each other along the sliding grooves 42, and symmetrical tooling positioning blocks 50 are respectively provided at the top of each of the first tooling positioning plates 51 and each of the second tooling positioning plates 52, and the adjusting structure 7 is respectively connected to the bottom of the first tooling positioning plate 51 and the second tooling positioning plate 52.

[0034] Specifically, the adjustment structure 7 includes a first rotating disk 71 and a second rotating disk 72 rotatably arranged in the circular rotating cavity 41, the first rotating disk 71 and the second rotating disk 72 are stacked up and down, and the first rotating disk 71 and the second rotating disk 72 are symmetrically penetrated with obliquely arranged strip grooves 73, and the first rotating disk 71 is provided with an arc-shaped giving way groove 74. A first plug rod 53 extending downward is provided on the bottom surface of each of the first tooling positioning plates 51, and the bottom end of each of the first plug rods 53 is inserted into the corresponding strip groove 73 on the first rotating disk 71. A second plug rod 54 extending downward is provided on the bottom surface of each of the second tooling positioning plates 52, and the bottom end of each of the second plug rods 54 passes through the corresponding giving way groove 74 and is inserted into the corresponding strip groove 73 on the second rotating disk 72. A first through hole 711 is penetrated in the center of the first rotating disk 71, and a second through hole 721 coaxial with the first through hole 711 is penetrated in the center of the second rotating disk 72. A driving member 8 that can move up and down is movably inserted in the first through hole 711 and the second through hole 721. The driving member 8 drives the first rotating disk 71 and the second rotating disk 72 to rotate by moving up and down respectively. A first driven annular tooth 712 is arranged around the inner wall of the circumference of the first through hole 711, and a second driven annular tooth 722 is arranged around the inner wall of the circumference of the second through hole 721. The inner diameter of the second through hole 721 is smaller than the inner diameter of the first through hole 711. The driving member 8 includes a movable The driving tube 81 passes through the first through hole 711 and the second through hole 721, and the first driving annular teeth 82 that can mesh with the first driven annular teeth 712 and the second driving annular teeth 83 that can mesh with the second driven annular teeth 722 are respectively provided on the circumferential outer wall surrounding the driving tube 81, and the first driving annular teeth 82 and the second driving annular teeth 83 are arranged with an upper and lower interval between them. The third through hole 43 passes through the bottom plate 44 in the circular rotating cavity 41, and the bottom of the driving tube 81 is inserted into the third through hole 43.

[0035] Please note that Figure 4 As shown, when the drive tube 81 is at a height where the first driven annular tooth 712 is meshed with the first active annular tooth 82 and the second driven annular tooth 722 and the second active annular tooth 83 at the same time, the first rotating disk 71 and the second rotating disk 72 cannot be adjusted individually. Therefore, this height is used to lock the rotation of the first rotating disk 71 and the second rotating disk 72. In order to lock the first rotating disk 71 and the second rotating disk 72, and then lock the two first tooling positioning plates 51 and the two second tooling positioning plates 52 in position, a positioning device 9 capable of positioning the up and down movement position of the drive tube 81 and a locking structure 10 capable of locking or releasing the horizontal rotation of the drive tube 81 are provided in the third through hole 43. Figures 4 to 7 as well as Fig. 9 and Fig.10 As shown, the positioning device 9 includes a first positioning ring groove 91 and a second positioning ring groove 92 which are arranged concavely around the circumferential outer wall of the driving tube 81. The first positioning ring groove 91 and the second positioning ring groove 92 are arranged at intervals up and down. A plurality of snap grooves 93 are arranged horizontally at intervals on the inner wall of the third through hole 43. Spring buckles 94 are installed in the spring buckle grooves 93. The head ends of the spring buckles 94 abut against the circumferential outer wall of the driving tube 81 and can be respectively embedded in the first positioning ring groove 91 or the second positioning ring groove 92 when the driving tube 81 moves up and down. When the spring buckle 94 is stuck in the first positioning ring groove 91, it means that the first driven annular tooth 712 is meshed with the first active annular tooth 82 and the second driven annular tooth 722 and the second active annular tooth 83 at the same time. At this time, the driving tube 81 can be prevented from rotating by cooperating with the locking structure 10, and the first rotating disk 71 and the second rotating disk 72 are also locked and cannot rotate. Specifically, the locking structure 10 includes a first locking annular tooth 11 surrounding the circumferential inner wall of the third through hole 43, and a second locking annular tooth 12 is provided around the circumferential outer wall of the driving tube 81 and can move up and down with the driving tube 81 to engage or disengage with the first locking annular tooth 11.

[0036] Also, see Figure 5 As shown, when it is necessary to drive the first rotating disk 71 to rotate alone, the driving tube 81 is pressed downward, the snap 94 is disengaged from the first positioning ring groove 91, the first locking annular tooth 11 and the second locking annular tooth 12 are dislocated and separated up and down, and the second active annular tooth 83 moves downward to disengage from the meshing with the second driven annular tooth 722, but because the thickness of the first active annular tooth 82 is greater than that of the second active annular tooth 83, after the second active annular tooth 83 is disengaged from the second driven annular tooth 722, the first active annular tooth 82 that has also moved downward will not disengage from the first driven annular tooth 712, but will continue to mesh with each other. At this time, the rotating driving tube 81 can drive the first rotating disk 71 to rotate, while the second rotating disk 72 will not rotate. In this way, the two first tooling positioning plates 51 will move toward or away from each other along the groove branch of the sliding groove 42, so as to adjust the position of the tooling positioning block 50 on the first tooling positioning plate 51. In order to facilitate the rotation of the driving tube 81 , a rotating handle 84 is transversely provided in the central tube hole at the top of the driving tube 81 .

[0037] See also Figure 6As shown, when it is necessary to adjust the straightness of the two second tooling positioning plates 52, it is necessary to lift the drive tube 81 upwards to allow the second active annular gear 83 to move up and engage with the second driven annular gear 722 again. At the same time, continue to lift the drive tube 81 upwards to disengage the first active annular gear 82 from the first driven annular gear 712, and the spring catch 94 is inserted into the second positioning ring groove 92. Turn the rotating handle 84 to drive the second rotating disk 72 to rotate alone. At this time, the second insertion rod 54 on the bottom surface of the second tooling positioning plate 52 is squeezed by the corresponding strip groove 73 on the second rotating disk 72, thereby pushing the two second tooling positioning plates 52 to move toward or away from each other along the groove branch of the sliding groove 42. After the adjustment is completed, the driving tube 81 is pressed down again, and the snap button 94 is squeezed out of the second positioning ring groove 92 and then snapped into the first positioning ring groove 91 again, and the first locking ring gear 11 and the second locking ring gear 12 are meshed with each other again, locking the rotation of the driving tube 81, and then the first driven ring gear 712 and the first active ring gear 82 and the second driven ring gear 722 and the second active ring gear 83 are meshed again at the same time. The position adjustment and locking of the tooling positioning assembly 5 on the rotating plate 4 are completed.
