Description

Technical Field

[0001] This utility model relates to the field of production line technology, specifically a lifting and force-bearing device for a production line pallet. Background Technology

[0002] In modern industrial production lines, both automated and manual, the pallet serves as the basic unit for carrying workpieces for transfer and processing. Its efficient and precise control is crucial for ensuring production efficiency and product quality.

[0003] When a pallet is lifted and subjected to certain operations (such as pressing), a large force is generated. If this force cannot be effectively supported by the lifting mechanism and transmitted to a stable base, but instead acts on the conveyor line, it may cause damage or deformation to the line, affecting its service life and conveying accuracy.

[0004] To address this, we propose a line tray lifting force-bearing device. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5 In this embodiment of the utility model, a line tray lifting force-bearing device includes a workbench 1, a movable line 2, a tray 3, a lifting mechanism, and a blocking mechanism.

[0025] Two moving lines 2 are fixedly connected to the upper surface of the workbench 1. A tray 3 is slidably connected to each moving line 2. A lifting mechanism is located below the tray 3. The lifting mechanism includes a lifting cylinder 7, a connecting plate 8, a connecting sleeve 19, a moving bar 10, a wedge block 18, a guide seat 9, a moving cylinder 13, and a positioning mechanism. A horizontally arranged lifting cylinder 7 is fixedly connected to the upper surface of the workbench 1. The output end of the lifting cylinder 7 is fixedly connected to the connecting plate 8 via the connecting sleeve 19. Moving bars 10 are fixedly connected to both ends of the connecting plate 8, and the moving bars 10 are slidably connected to the upper surface of the workbench 1. The four corners of the lower surface of the tray 3 are connected to the moving cylinder 13 via the positioning mechanism. The moving cylinder 13 slides within the guide seat 9, which is fixed to the upper surface of the workbench 1. The lower surface of the slide is provided with a groove, and the moving bar 10 passes through the groove and is slidably connected to it. The upper surface of the moving bar 10 is provided with two moving grooves 15, and a wedge block 18 is fixedly connected in the moving groove 15. The bottom end of the moving cylinder 13 is fixedly connected with an adjusting rod 17. The two ends of the adjusting rod 17 pass through the adjusting grooves 16 on both sides of the bottom end of the guide seat 9 and are slidably connected to them. The bottom end of the moving cylinder 13 is provided with a through groove. The outside of the adjusting rod 17 located in the through groove is rotatably connected with a rolling bearing 14. The rolling bearing 14 contacts the wedge block 18. The positioning mechanism includes a positioning pin 11 and a positioning block 5. The four corners of the lower surface of the tray 3 are fixedly connected with positioning blocks 5. The top end of the moving cylinder 13 is fixedly connected with a positioning pin 11. The positioning pin 11 is inserted into the positioning block 5 and contacts it.

[0026] It should be noted that this device achieves a smooth, low-friction lifting action by using a cylinder to drive the wedge block 18 in conjunction with the rolling bearing 14, and ensures the stability of the lifting and lowering through a guide structure. Finally, the positioning mechanism ensures the precise positioning of the pallet 3 after it is lifted.

[0027] This device achieves the lifting and lowering of the tray 3 by setting a horizontal lifting cylinder 7 on the workbench 1. When the lifting cylinder 7 is working, its output end drives the connecting plate 8 through the connecting sleeve 19, which in turn drives the two moving bars 10 to slide on the workbench 1. The moving bars 10 pass through the groove on the lower surface of the guide seat 9 fixed to the upper surface of the workbench 1 and slide in this groove. The fixed wedge block 18 also moves horizontally accordingly.

[0028] When the wedge block 18 moves horizontally, its contact with the rolling bearing 14 smoothly converts the horizontal movement into the vertical lifting and lowering movement of the moving cylinder 13. The use of the rolling bearing 14 changes the force transmission between the wedge block 18 and the moving cylinder 13 (through the adjusting rod 17) from sliding friction to rolling friction, which significantly reduces frictional resistance, making the lifting process smoother and less strenuous, and helps to improve the response speed and service life of the mechanism.

[0029] The moving cylinder 13 slides inside the guide seat 9, while the two ends of the adjusting rod 17 at its bottom end slide in the adjusting grooves 16 on both sides of the bottom end of the guide seat 9. This double guidance ensures the stability of the moving cylinder 13 during the lifting process, prevents it from shaking or deflecting, and provides a guarantee for the smooth lifting of the tray 3.

[0030] The four corners of the lower surface of the tray 3 are connected to the top of the moving cylinder 13 through a positioning mechanism. When the moving cylinder 13 rises and drives the tray 3, the positioning pin 11 will be inserted into the corresponding positioning block 5 and contact it. This pin-hole cooperation method enables the tray 3 to be accurately positioned when it is lifted to the predetermined position, ensuring the accuracy of the tray position in subsequent processes.

[0031] The upper surface of the workbench 1 is provided with a blocking mechanism, which includes a blocking cylinder seat 12, a fixing block 6, and a connecting arm 20. Two fixing blocks 6 are fixedly connected to the rear end face of the tray 3. Two symmetrically distributed blocking cylinder seats 12 are fixedly connected to the upper surface of the workbench 1. Each blocking cylinder seat 12 is movably connected to a connecting arm 20. The connecting arm 20 is driven so that its free end contacts the corresponding fixing block 6. Guide strips 4 are fixedly connected to both sides of the lower surface of the tray 3. The guide strips 4 contact the inner end face of the moving line 2. Wear-resistant strips are fixedly connected to both sides of the lower surface of the tray 3. The wear-resistant strips contact the upper surface of the moving line 2.

[0032] It should be noted that, in order to ensure that the pallet 3 can be accurately positioned before entering the lifting station, the device is also equipped with a blocking mechanism on the upper surface of the workbench 1. When the pallet 3 moves to the predetermined position along the moving line 2, the cylinder in the blocking cylinder seat 12 drives the connecting arm 20 to move, so that its free end contacts the fixed block 6 on the pallet 3, thereby blocking the pallet 3 and realizing the coarse positioning of the pallet in the direction of movement on the line 2, which provides a prerequisite for subsequent lifting operations.

[0033] Furthermore, to ensure that the tray 3 slides smoothly and accurately on the moving line 2, the guide strip 4 contacts the inner end face of the moving line 2, which plays a lateral guiding role when the tray 3 moves along the line, preventing unnecessary lateral deviation of the tray 3 and ensuring its stable movement along the predetermined trajectory. In addition, wear-resistant strips are further fixedly connected to both sides of the lower surface of the tray 3. These wear-resistant strips directly contact the upper surface of the moving line 2, which can effectively reduce the wear of the tray body and the upper surface of the line, and extend the service life of the components.

[0034] In summary, this utility model uses a horizontal cylinder 7 to drive the connected moving bar 10 and the fixed wedge block 18, which cooperate with the rolling bearing 14 at the bottom of the moving cylinder 13 to efficiently and smoothly convert horizontal motion into vertical lifting of the tray 3, achieving low-friction lifting action. The moving cylinder 13 achieves stable movement under dual guidance in the guide seat 9 and the adjusting groove 16. The positioning pin 11 at its top cooperates with the positioning block 5 on the tray 3 to ensure accurate positioning after lifting. In addition, the blocking mechanism on the worktable 1 drives the connecting arm 20 to contact the fixed block 6 on the tray 3 through the cylinder, completing the coarse positioning of the tray in the direction of movement of the line body 2. At the same time, the guide bar 4 at the bottom of the tray 3 provides lateral guidance in the moving line body 2 to prevent deviation, while the wear-resistant strip reduces the sliding wear between the tray and the line body 2, together ensuring the stability and durability of the device operation and extending the service life of the components.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
