Description

Technical Field

[0001] This utility model relates to the field of positioning equipment technology, specifically to a detachable vehicle positioning device and positioning production line. Background Technology

[0002] In modern automated component manufacturing lines, rapid equipment changeover when producing different component models is a key aspect of ensuring production flexibility and efficiency. Currently, the lifting and positioning mechanism commonly used in production lines, as the core component for material conveying and positioning, has significant shortcomings in its changeover method.

[0003] In existing technologies, lifting and positioning mechanisms often employ a lifting plate on a cylinder or other actuator to position different carriers. This lifting plate is rigidly locked to the lower cylinder with screws. In practice, when the lifting plate needs to be replaced to accommodate different components or for disassembly and maintenance, its rigid connection to the cylinder causes the cylinder's extension rod to rotate with the support plate. This prevents operators from performing the lifting plate's disassembly and assembly on the production line. Therefore, the entire positioning device must be removed from the production line for modification and adjustment before reinstallation and debugging. This process is not only cumbersome but also significantly extends equipment downtime, severely impacting production efficiency.

[0004] Furthermore, frequent disassembly and installation can easily cause wear and tear on equipment components, reducing equipment lifespan and increasing maintenance costs and failure risks. With the increasing market demand for diversified components, traditional lifting mechanism replacement methods are no longer sufficient to meet the needs of modern, efficient, and flexible production. There is an urgent need for a new type of lifting mechanism technology that can achieve rapid in-situ replacement and improve production efficiency. Summary of the Invention

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Example 1:

[0026] See Figure 1 and Figure 2As shown, this embodiment provides a detachable vehicle positioning device, which includes: a support assembly 200, the support assembly 200 including a lifting plate 240 and a positioning plate 230, the positioning plate 230 being supported on the lifting plate 240; and a drive mechanism 100, the drive mechanism 100 including a lifting driver 110, an extension screw 120, and a locking screw 130, one end of the extension screw 120 being provided with a fixing nut 121, and the other end being connected to the working end of the drive mechanism 100, the extension screw 120 passing through both the lifting plate 240 and the positioning plate 230, and the locking screw 130 being connected to the lifting plate 240 and the positioning plate 230. The extension screw 120 is threaded, wherein the fixing nut 121 is embedded in the positioning plate 230, and the locking screw 130 abuts against the bottom surface of the lifting plate 240 to fix the lifting plate 240 and the positioning plate 230 to the extension screw 120; the disassembly and assembly mechanism 300 includes a snap-fit ​​connector 310 and an extension component 320. The snap-fit ​​connector 310 is snapped into the locking screw 130, and one end of the extension component 320 is connected to the snap-fit ​​connector 310, and the other end can extend through the installation gap between the drive mechanism 100 and the external production line to the top of the drive mechanism 100.

[0027] Among them, the support component 200 is used to directly support the vehicle to be positioned, the drive mechanism 100 is used to provide vertical driving power for the support component 200, and the disassembly and assembly mechanism 300 is used to realize flexible disassembly and assembly between the support component 200 and the drive structure in different scenarios.

[0028] In this embodiment, the lifting plate 240 in the support assembly 200 serves as a basic support component for the equipment, directly bearing the lifting force from the drive mechanism 100 and evenly distributing this force to the positioning plate 230 and the carrier. Driven by the drive mechanism 100, the lifting plate 240 achieves vertical lifting movement, providing a stable lifting platform for the carrier and ensuring its stability during ascent or descent, avoiding tilting or swaying due to uneven force. Furthermore, the lifting plate 240 provides a contact surface for the locking screw 130, thereby enabling it to cooperate with the extension screw 120 and the locking screw 130 to achieve a secure connection with the positioning plate 230. Furthermore, the detachable carrier positioning device in this embodiment is suitable for assembly line production, and its installation space is confined. Therefore, in this embodiment, there is a risk that the lifting plate 240 may restrict the movement or installation of the detachment mechanism 300. Based on this, the lifting plate 240 in this embodiment also includes a clearance groove 241, which is provided corresponding to the second extension arm 322. The second extension arm 322 passes through the clearance groove 241 to the top of the drive mechanism 100. The position of the clearance groove 241 corresponds to the movement path of the second extension arm 322, thereby ensuring that the second extension arm 322 can pass through the lifting plate 240 without obstruction and extend to the top of the drive mechanism 100. Through this design, the restriction of the lifting plate 240 on the movement or installation of the detachment mechanism 300 is effectively eliminated, allowing operators to flexibly operate the locking screw 130 through the extension component 320 outside the production line without worrying about space interference.

[0029] The positioning plate 230 in the support assembly 200 is available in different models according to the shape and positioning requirements of the carrier. It can precisely define the position of the carrier, ensuring that the carrier maintains a fixed posture during processing, inspection, and other processes, thereby guaranteeing processing accuracy and the accuracy of inspection results. Specifically, the positioning plate 230 has multiple positioning holes 233, and the support assembly 200 also includes multiple positioning pins 231, which can be disposed in the positioning holes 233. In this embodiment, two positioning pins 231 are included, respectively disposed on the diagonal of the positioning plate 230. In different embodiments, the positioning plate 230 can achieve its positioning function for the carrier by setting other numbers or positions of positioning pins 231, or by designing other positioning structures. This utility model does not impose specific limitations in this regard.

[0030] See Figures 1 to 3As shown, in this embodiment, the lifting plate 240 has a first mounting hole that extends through its thickness direction at its center, and the positioning plate 230 has a second mounting hole 232 that extends through its thickness direction at its center. The first mounting hole and the second mounting hole 232 are interconnected, and the extension screw 120 passes through the first mounting hole and the second mounting hole 232, thereby realizing the connection between the drive mechanism 100 and the lifting plate 240 and the positioning plate 230.

[0031] In this embodiment, the lifting actuator 110 serves as the power source for the equipment. By outputting linear driving force, it drives the extension screw 120 to vertically raise and lower the lifting plate 240 and the positioning plate 230, thereby achieving the lifting and lowering of the carrier. It can precisely control the lifting speed and height according to actual production needs to adapt to different production cycles and carrier positioning requirements. One end of the extension screw 120 is embedded in the positioning plate 230 through a fixing nut 121, and the other end is connected to the working end of the lifting actuator 110, forming a connecting shaft that passes through the lifting plate 240 and the positioning plate 230. During equipment operation, it cooperates with the locking screw 130 to firmly fix the lifting plate 240 and the positioning plate 230 together, ensuring synchronous movement during lifting and maintaining the stability of the carrier positioning. The locking screw 130 is threadedly engaged with the extension screw 120, allowing for quick fixing and separation of the lifting plate 240 and the positioning plate 230 through tightening or loosening operations. When the locking screw 130 is tightened, its end face tightly abuts against the bottom surface of the lifting plate 240, pressing the lifting plate 240 and the positioning plate 230 tightly onto the extension screw 120 to prevent relative displacement between the two. When changing models, simply loosen the locking screw 130 to release the fixed state of the lifting plate 240 and the positioning plate 230, making it easy to quickly replace the positioning plate 230.

[0032] Specifically, the drive mechanism 100 also includes a buffer spring 140, which is disposed between the fixing nut 121 and the locking screw 130. The buffer spring 140 absorbs the starting and stopping impact during the lifting process through elastic deformation, transforming the instantaneous rigid collision into the flexible buffer of the spring, avoiding plastic deformation or thread damage to components such as the fixing nut 121, locking screw 130, and extension screw 120 due to impact, and extending the service life of the equipment.

[0033] Furthermore, the drive mechanism 100 in this embodiment also includes a drive sensor 150 and a connecting frame 260. The connecting frame 260 is fixed to the lifting plate 240 and moves synchronously with the lifting plate 240. The drive sensor 150 is connected to the connecting frame 260 and includes two detection ends symmetrically arranged in the vertical direction. Specifically, in this embodiment, the two detection ends are respectively arranged in the upward and downward directions to accurately calibrate the lifting action of the lifting plate 240 and the positioning plate 230.

[0034] In this embodiment, to ensure that the lifting plate 240 and the positioning plate 230 can always move vertically, the support assembly 200 further includes at least one guide shaft 220 and at least one guide sleeve 250, each corresponding to a different guide shaft 220. The guide sleeve 250 is connected to the bottom surface of the lifting plate 240, and the guide shaft 220 extends vertically, with one end connected to the mounting surface and the other end slidingly inserted into the guide sleeve 250. This structure mechanically forces the lifting plate 240 and the positioning plate 230 to move along the axis of the guide shaft 220, eliminating horizontal displacement deviation. Furthermore, the support assembly 200 also includes at least one oil-absorbing block 210, with each oil-absorbing block corresponding to at least one guide shaft 220, and the oil-absorbing block 210 is fitted onto the outer surface of the guide shaft 220. During long-term operation of the equipment, metal debris or production line dust generated by the friction between the guide shaft 220 and the guide sleeve 250 easily accumulates in the gap between the sliding pairs. The oil-absorbing block 210 is made of a high-porosity oil-absorbing material and is sleeved on the outer surface of the guide shaft 220. It can be pre-wetted with lubricating oil. When the lifting plate 240 moves up and down along the guide shaft 220, the oil-absorbing block 210 and the guide shaft 220 slide relative to each other, continuously releasing lubricating oil to form an oil film, which reduces the coefficient of friction between the guide shaft 220 and the guide sleeve 250, thereby reducing most of the wear between them.

[0035] See Figure 1 and Figure 4 As shown, the snap-fit ​​connector 310 in the disassembly / assembly mechanism 300 is designed to match the shape of the locking screw 130, allowing it to snap tightly onto the locking screw 130 and ensuring effective force transmission during operation. One end of the extension assembly 320 is connected to the snap-fit ​​connector 310, and the other end passes through the installation gap between the drive mechanism 100 and the external production line, extending to the top of the drive mechanism 100. This allows operators to manipulate the snap-fit ​​connector 310 from outside the production line, thereby completing the disassembly / assembly of the locking screw 130. The extension assembly 320 includes a first extension arm 321 and a second extension arm 322 connected perpendicularly to each other. One end of the first extension arm 321 is connected to the snap-fit ​​connector 310, and the other end extends horizontally away from the snap-fit ​​connector 310. The second extension arm 322 is connected to the free end of the first extension arm 321 and extends vertically to the top of the drive mechanism 100. The perpendicular connection of the first extension arm 321 and the second extension arm 322 forms an "L"-shaped lever, thereby avoiding the narrow gap between the equipment and the production line. The second extension arm 322 extends vertically to the top of the drive mechanism 100, transforming the original action of assembling and disassembling the locking screw 130, which originally had to be completed in the narrow space at the bottom of the equipment, into an operation in the open area at the top, thus significantly improving the tool's operating space.

[0036] Example 2:

[0037] This embodiment provides a positioning production line, which includes the aforementioned detachable carrier positioning device and a transmission line. The detachable carrier positioning device is disposed on the transmission path of the transmission line. The drive mechanism 100 in the detachable carrier positioning device is connected to the lower part of the transmission line. The positioning plate 230 in the detachable carrier positioning device can be lifted vertically from the bottom of the transmission line to the top of the transmission line. The extension component 320 in the detachable carrier positioning device can extend through the installation gap between the drive mechanism 100 and the external production line to the top of the drive mechanism 100.

[0038] In summary, the detachable carrier positioning equipment and positioning production line of this utility model uses the drive mechanism 100 to drive the support assembly 200 to position the components. When the positioning plate 230 needs to be disassembled and replaced, the locking screw 130 can be fixed by the disassembly and assembly mechanism 300, thereby avoiding the problem of difficulty in relative rotation between the locking screw 130 and the extension screw 120. At the same time, based on the special structural design of the disassembly and assembly mechanism 300, it can be applied to various narrow working spaces. Based on this, compared with the existing conventional lifting and positioning structure design, this application has the advantages of wide applicability, convenient operation, and stable operation process, and simply and efficiently overcomes the problem of difficulty in disassembling and assembling the lifting plate 240 on the production line in the prior art.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
