Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] like Figures 2-7 As shown, this utility model provides an automatic switching device for a skid fulcrum, comprising: a first translation component and a second translation component; the first translation component is disposed on the top of a bracket 1 and detachably connected to the bracket 1, the second translation component is disposed on the top of the first translation component and movably connected to the first translation component, the first translation component is used to drive the second translation component to translate, the second translation component is provided with a docking component, the second translation component is used to drive the docking component to translate, and the docking component is used to unlock, adjust and lock the skid fulcrum.

[0036] The working principle and beneficial effects of the above technical solution are as follows: Through the design of the above structure, when adjusting the fulcrum position, the first translation component will drive the second translation component to move to the position corresponding to the skid fulcrum. Then, the second translation component will drive the docking component to move, and the docking component will connect with the skid fulcrum and unlock it. The first translation component will drive the second translation component to move, and the second translation component will drive the docking component to move. In turn, the docking component will adjust the position of the skid fulcrum on the fulcrum mounting track 100. When the skid fulcrum is adjusted to the appropriate position, the second translation component will drive the docking component to reset, and the docking component will separate from the skid fulcrum. After the docking component separates from the skid fulcrum, the skid fulcrum will automatically lock and will no longer displace relative to the fulcrum mounting track 100. This achieves automatic position adjustment of the skid fulcrum. The entire process does not require manual intervention, which can significantly reduce adjustment time and improve production efficiency while ensuring the accuracy of the adjustment position. At the same time, it does not require personnel to intervene in the mechanical system, which can effectively reduce operational safety hazards.

[0037] Furthermore, the first translation component consists of a first drive group and at least one first track 2. The first track 2 is detachably connected to the bracket 1. The bracket 1 can be composed of a support leg or other structure necessary for mounting the first translation component. The second translation component is disposed on the first track 2 and is movably connected to the first track 2, so that the second translation component can translate on the first track 2, thereby realizing the position adjustment of the second translation component. The first drive group is detachably connected to the second translation component or the bracket 1. Depending on the implementation method, the installation position of the first drive group is also different. The first drive group can be installed on the second translation component (see the following embodiment) or on the bracket 1, as long as it enables the second translation component to translate on the first track 2.

[0038] Furthermore, to facilitate the installation of the first drive group and the first track 2, and to maintain the integrity of the first translation component structure, the first translation component also includes a first frame 3, which can be as follows: Figure 2 The rectangular frame shown has a first frame 3 positioned on top of the bracket 1 and detachably connected to it. Typically, the bracket 1 can be constructed as follows: Figure 2 The support legs shown are respectively located at the four corners of the first frame 3. The first track 2 is located at the top of the first frame 3. Typically, two first tracks 2 are provided, each resting on one of the two sidewalls of the first frame 3 parallel to the support mounting track 100. Figure 2 As shown.

[0039] Furthermore, as one of many embodiments, the first drive group consists of a drive motor 4, a transmission gear 5, and a toothed track 6. The toothed track 6 is mounted on the first frame 3 or bracket 1 and is parallel to the first track 2. The top surface of the toothed track 6 is provided with teeth that mesh with the transmission gear 5. Two toothed tracks 6 can be provided, meshing from the upper and lower directions of the transmission gear 5. The transmission gear 5 is mounted on the drive shaft of the drive motor 4. The drive motor 4 is mounted at the bottom of the second translation component. When it is necessary to adjust the position of the second translation component, the drive motor 4 is started, thereby causing the transmission gear 5 to rotate. Because the toothed track 6 is mounted on the first frame 3 or bracket 1, when the transmission gear 5 rotates, it will drive the drive motor 4 to move, thereby driving the second translation component connected to the drive motor 4 to move.

[0040] Furthermore, the second translation component comprises a second frame 7, a second drive group 8, at least one second track 9, and at least one first slider 10. The drive motor 4 is mounted on the bottom of the second frame 7, the second drive group 8 is disposed on the second frame 7, and the second drive group 8 is connected to the docking component for driving the docking component to move. The second drive group 8 is a telescopic device; for example, the second drive group 8 can be... Figure 2 The pneumatic telescopic device (a conventional combination of a cylinder and a telescopic rod) shown is connected to the docking assembly via the telescopic rod of the pneumatic telescopic device; the second drive group 8 can also be a hydraulic telescopic device (a conventional combination of a hydraulic cylinder and a push rod); it can also be a gear combination or worm gear combination as described in the first drive group. The second track 9 is set on the top surface of the second frame 7, and the second track 9 has a non-zero included angle with the first track 2. Usually, the second track 9 is perpendicular to the first track 2, but the position of the second track 9 can be adjusted according to the site conditions. The docking assembly is movably connected to the second track 9, thereby allowing the second drive group 8 to drive the docking assembly to move along the second track 9. The first slider 10 is set at the bottom of the second frame 7 and is movably connected to the first track 2.

[0041] When adjusting the position of the second translation component, the second frame 7 can move on the first track 2 via the first slider 10. When adjusting the position of the docking component, the cylinder of the second drive group 8 (taking a pneumatic telescopic device as an example) is activated, the telescopic rod on the cylinder extends, pushing the docking component along the second track 9, pushing the docking component towards the skid fulcrum until the docking component connects with the skid fulcrum. When retracting, the telescopic rod retracts into the cylinder, and the docking component is retracted to the initial position along the second track 9.

[0042] Furthermore, the docking assembly consists of a mounting plate 11, an unlocking component 12, a locking plate assembly 13, and at least one second slider 14. The unlocking component 12 and the locking plate assembly 13 are both disposed on the mounting plate 11, and both the unlocking component 12 and the locking plate assembly 13 extend from the mounting plate 11 toward the sliding fulcrum.

[0043] The unlocking component 12 can consist of a first vertical tube connected to the mounting plate 11 and a first horizontal tube extending towards the skid fulcrum. The bottom of the first vertical tube is connected to the top of the mounting plate 11, and an angle iron can be provided at the connection point to increase its strength. One end of the first horizontal tube is connected to the top of the first vertical tube, and the other end is provided with a contact for unlocking and locking the skid fulcrum. A tie rod can be added between the first horizontal tube and the first vertical tube to improve the strength of the connection.

[0044] The clamping plate assembly 13 can be composed of a second riser connected to the mounting plate 11 and two clamps extending towards the fulcrum of the sliding skid. The bottom of the second riser is connected to the top of the mounting plate 11. An angle iron can be set at the connection to increase the firmness. The two clamps are respectively set on two opposite side walls of the second riser. Both clamps are perpendicular to the fulcrum mounting rail 100. The clamping plate assembly 13 can clamp and adjust the position of the sliding skid fulcrum through the two clamps. The second slider 14 is set at the bottom of the mounting plate 11 and is movably connected to the second rail 9, thereby allowing the docking assembly to move horizontally on the second rail 9. The second drive group 8 is connected to the mounting plate 11, or the unlocking member 12 (the first riser), or the clamping plate assembly 13 (the second riser).

[0045] To further address the aforementioned issue of the inability to adapt to constantly evolving vehicle frames, we also provide a skid fulcrum, which is set on the fulcrum mounting rail 100 and includes a third rail 15, a fulcrum mounting bracket 16, a locking device 17, a positioning device 18, and at least one third slider 19. The third rail 15 is set on the fulcrum mounting rail 100 of the conveyor line and is parallel to the fulcrum mounting rail 100. The third rail 15 is usually set on the top surface of the fulcrum mounting rail 100 to support the fulcrum mounting bracket 16, while also saving the equipment's floor space.

[0046] The third slider 19 is located at the bottom of the fulcrum mounting frame 16 and is movably connected to the third track 15. The locking device 17 is located on the fulcrum mounting frame 16. The fulcrum mounting frame 16 can be a rectangular frame structure with two third risers and two second horizontal pipes, or it can be an n-shaped structure with two third risers and one second horizontal pipe. The second horizontal pipe is used to connect the two third risers. The third slider 19 is located at the bottom of the third risers, and the second horizontal pipe ensures the synchronous movement of the two third risers along the third track 15.

[0047] The positioning device 18 is disposed on the third track 15 or the fulcrum mounting track 100, as long as the positioning device 18 is installed in a position that can remain relatively stationary with respect to the fulcrum mounting track 100. The locking device 17 is connected to the positioning device 18 and is used to limit the position between the third slider 19 and the third track 15. As one of many embodiments, the positioning device 18 can be as follows: Figure 7 The L-shaped sheet structure shown has multiple openings and slots for locking; it can also be a strip structure with teeth.

[0048] As one of many embodiments, the locking device 17 may consist of a connector connected to the fulcrum mounting bracket 16, a mounting member disposed on the connector, a locking block and a torsion spring disposed within the mounting member, wherein the locking block is shaft connected within the mounting member, and the torsion spring is sleeved on the shaft connecting the locking block and the mounting member, and always keeps the locking block moving toward the locking position.

[0049] When the contact is not in contact with the locking block, the locking block is in the locking position, and the locking device 17 and the positioning device 18 are connected through the locking block;

[0050] When the contact abuts against and pushes the locking block, the locking block is pushed out of the locking position by the contact, and the locking device 17 is disconnected from the positioning device 18.

[0051] The unlocking component 12 is selectively connected to the locking device 17;

[0052] The plate assembly 13 is selectively connected to the fulcrum mounting bracket 16.

[0053] The top of the fulcrum mounting bracket 16 is provided with a detachable fulcrum 200.

[0054] When the docking assembly adjusts the position of the skid fulcrum, the mounting plate 11 first moves along the second track 9 under the drive of the second drive group 8 until the contact of the unlocking member 12 connects with the locking device 17 on the skid fulcrum, unlocking the locking device 17 and the positioning device 18. At the same time, the two clamps of the clamping plate assembly 13 clamp the fulcrum mounting frame 16. At least one third riser of the fulcrum mounting frame 16 will be located between the two clamps. Then the drive motor 4 starts, driving the transmission gear 5 to rotate. The transmission gear 5 carries the drive motor 4 to move along the toothed track 6, thereby causing the second frame 7 to move the clamping plate assembly 13 to move. Thus, the clamping plate assembly 13 can move along the third track 15 to adjust the position of the fulcrum mounting frame 16.

[0055] After the position is adjusted (usually the locking device 17 moves to the locking position of the positioning device 18), the second drive group 8 drives the docking component to reset, the clamping plate of the clamping plate component 13 separates from the fulcrum mounting bracket 16, and at the same time the contact of the unlocking component 12 separates from the locking device 17. The locking device 17 locks with the positioning device 18, thereby fixing the fulcrum mounting bracket 16 on the third track 15. Finally, the fulcrum 200 of different heights is replaced on the top of the fulcrum mounting bracket 16 (a pad can be added if necessary) to adjust the vertical height of the fulcrum 200.
