More importantly, this manual approach cannot meet the high-precision positioning requirements of modern automated production lines. Automated production strives for precise, efficient, and consistent workflows, and manual intervention often struggles to match this level of precision and efficiency. Utility Model Content

[0024] The embodiment of the present application solves the problems of complicated processes and positioning errors in the prior art by providing a self-locking lifting mechanism, thereby achieving the technical problems of simplifying the workflow and ensuring positioning accuracy.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0027] like Figures 1-6As shown, the self-locking jacking mechanism provided in the embodiment of the present application includes: a mounting base 100, a driving assembly 200, a transmission assembly 300 and a jacking assembly 400.

[0028] Specifically, the mounting base 100 includes a base plate 110 and a guide plate 120 vertically mounted on one end of the base plate 110. The guide plate 120 can be an L-shaped structure or a structure of other shapes, as long as it can play a guiding role.

[0029] Specifically, the driving assembly 200 includes a driving motor 210, which is mounted on the mounting base 100 relative to the guide plate 120. The driving motor 210 and the guide plate 120 are disposed at opposite ends of the base plate 110.

[0030] Specifically, the transmission assembly 300 includes a first transmission shaft 310, a second transmission shaft 320, and a third transmission shaft 330. The first transmission shaft 310 is fixedly mounted on the base plate 110, and the two ends of the second transmission shaft 320 are hinged to the first transmission shaft 310 and the third transmission shaft 330 respectively. The second transmission shaft 320 is connected to the driving end of the drive motor 210. For example, the first transmission shaft 310 can be mounted on the base plate 110 via a bearing, and one end of the second transmission shaft 320 can be mounted on the first transmission shaft 310 via a bearing, and the other end can be mounted on the third transmission shaft 330 via a bearing, thus forming two rotating joints, making the entire structure more flexible and convenient for later maintenance and replacement. Of course, the first transmission shaft 310, the second transmission shaft 320, and the third transmission shaft 330 can also be mounted together by welding, or fixed together by fasteners such as bolts, as long as the transmission function can be achieved.

[0031] Specifically, the lifting assembly 400 includes a guide rail 410 mounted on the guide plate 120 and a slider 420 mounted in conjunction with the guide rail 410. The slider 420 is connected to the third transmission shaft 330 and moves linearly along the guide rail 410 under the action of the drive motor 210. In other words, when the drive motor 210 is energized, it drives the second transmission shaft 320 to rotate. Since the second transmission shaft 320 is connected to the third transmission shaft 330, the third transmission shaft 330 also rotates, thereby driving the slider 420 to move upward along the guide rail 410, ultimately achieving the lifting action of the workpiece.

[0032] In summary, the self-locking jacking mechanism provided in the embodiment of the present application, by providing a mounting base 100, can provide a mounting base for the entire structure; by providing a drive assembly 200, can provide a power source for the entire structure; by providing a transmission assembly 300, can transmit the power of the drive motor 210 to the jacking assembly 400; and by providing the jacking assembly 400, can move linearly along the guide rail 410 under the action of the drive motor 210 to complete the jacking action of the workpiece. This solves the problems of cumbersome processes and positioning errors in the prior art, and achieves the technical problem of simplifying the workflow and ensuring positioning accuracy.

[0033] As an optional implementation, Figures 1-6 As shown, the self-locking jacking mechanism also includes a height adjustment assembly 500, which includes a first adjustment block 510 and a second adjustment block 520. The first adjustment block 510 is fixedly mounted on one side of the slider 420. The second adjustment block 520 is vertically mounted on the base plate 110, with a third adjustment block 530 positioned between the first and second adjustment blocks 510, 520. This allows the slider 420 to slide between the base plate 110 and the second adjustment block 520. This allows the slider 420 to slide in height by simply changing the height of the third adjustment block 530, thereby adjusting the required workpiece size.

[0034] As an optional implementation, Figures 1-6 As shown, the jacking assembly 400 further includes a support block 430. The support block 430 is fixedly mounted on the side of the slider 420 away from the first adjustment block 510. When the slider 420 reaches its highest position, the support block 430 contacts the workpiece, acting together with the slider 420 to bear the weight and achieve a self-locking effect.

[0035] As an optional implementation, Figures 1-6 As shown, the lifting assembly 400 further includes a positioning pin 440. The positioning pin 440 is mounted on the slider 420 near the support block 430. The portion of the positioning pin 440 extending from the outer surface of the slider 420 can be inserted into the hole of the workpiece to be processed, thereby controlling the position of the workpiece and preventing the workpiece from shifting.

[0036] As an optional implementation, Figures 1-6 As shown, the height adjustment assembly 500 further includes a shim 540. Shim 540 is movably positioned between the second adjustment block 520 and the third adjustment block 530. This allows the sliding height of the slider 420 to be adjusted quickly and easily by simply changing the number or thickness of shims 540, without requiring disassembly or installation, significantly reducing preparation time.

[0037] As an optional implementation, Figures 1-6As shown, the height adjustment assembly 500 also includes: a limit plate 600 and a limit pin 700. The limit plate 600 is vertically mounted on the base plate 110 and is located between the slider 420 and the transmission assembly 300. The limit pin 700 is mounted on the limit plate 600 and abuts against the transmission assembly 300. The limit plate 600 is mounted between the slider 420 and the transmission assembly 300, ensuring the transmission track of the transmission assembly 300 and preventing the slider 420 from deviating from the track and causing a safety accident. By adjusting the length of the limit pin 700, the minimum distance between the transmission assembly 300 and the slider can be adjusted, thereby adjusting the sliding stroke of the slider 420.

[0038] As an optional implementation, Figures 1-6 As shown, the mounting base 100 further includes a support plate 800. The first transmission shaft 310 and the drive motor 210 are mounted on either end of the support plate 800, respectively. The drive motor 210 is hingedly connected to the support plate 800. This supports the support plate 800, which not only strengthens the overall rigidity of the mounting base 100 and improves its load-bearing capacity, but also provides protection for the first transmission shaft 310 and the drive motor 210, extending their service life.

[0039] As an optional implementation, Figures 1-6 As shown, a drive shaft 900 is installed between the drive motor 210 and the second transmission shaft 320. The drive shaft 900 can play a role in buffering and shock absorption, reducing noise while protecting the drive motor 210 from damage.

[0040] It should be noted that the components among the various embodiments of the present disclosure can be interchangeable as long as they can play the corresponding roles.
