Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to a quick-change structure. Background Art

[0002] To improve production yield, product positioning on a production line is often necessary. This is typically accomplished using a fixture designed to match the product's dimensions. Because different product models may be produced on the same production line, the fixture must be replaced when a product changes model.

[0003] Most product fixtures are secured with screws. When replacing a fixture, the screws must be removed and the corresponding fixture for the next model must be installed with the screws. This significantly reduces product changeover time and production efficiency. Therefore, a new solution is needed to quickly disassemble and assemble fixtures. Summary of the Invention

[0004] The present invention provides a quick-change structure to solve the technical problem of rapid disassembly and assembly of structural parts on a production line.

[0005] The present invention provides a quick-change structure, which includes a first connecting component and a second connecting component, wherein the first connecting component includes an adapter, and the adapter is provided with a first positioning portion and a clamping portion; the second connecting component includes a limit plate, a locking component, and a handle, and the limit plate is provided with a second positioning portion that cooperates with the first positioning portion, and the locking component is slidably connected to the limit plate, and the handle has a rotating end rotatably connected to the limit plate, and the rotating end is rollingly connected to the locking component. Rotating the handle drives the locking component to move closer to or away from the clamping portion to lock or release the first connecting component.

[0006] The above-mentioned structure can realize the rapid installation and disassembly of structural parts, which is beneficial to improving the changeover efficiency of the production line, and is also beneficial to improving the stability of the production line, thereby improving the production efficiency of the production line.

[0007] In one embodiment of the present invention, the second connecting component also includes a connecting rod and a first connecting shaft, the connecting rod is rotatably connected to the locking piece, and a limit bar hole is provided on the connecting rod; the first connecting shaft is provided on the rotating end and passes through the limit bar hole; when the handle is rotated, the first connecting shaft moves in the limit bar hole.

[0008] When the first connecting shaft moves to the first end or the second end of the limiting bar hole, the handle continues to rotate, which will drive the locking piece to move closer to or away from the clamping portion to achieve locking or release of the first connecting component.

[0009] In one embodiment of the present invention, the second connecting component further includes a first elastic preload and a second elastic preload relatively arranged, the first elastic preload is located on the side of the rotating end away from the locking member, and the second elastic preload is located on the side of the locking member away from the rotating end; when the handle is rotated to bring the locking member closer to the clamping portion, both the first elastic preload and the second elastic preload are compressed.

[0010] When the first elastic preload and the second elastic preload are both compressed, the first elastic preload applies a first force toward the locking piece to the rotating end of the handle, and the second elastic preload applies a second force toward the handle to the locking piece. Under the action of the first force and the second force, the handle and the locking piece will remain fixed in the absence of other external forces, which is beneficial to ensuring the stability of the connection between the first connecting component and the second connecting component, and further beneficial to ensuring the stability of production line production.

[0012] By providing an accommodating hole in the limiting plate, the first elastic preloaded member is installed, and the first force applied by the first elastic preloaded member to the first rotating shaft is transmitted to the handle via the first rotating shaft, thereby ensuring the stability of the connection between the first connecting member and the second connecting member. By providing an accommodating groove in the limiting plate, the locking member presses the second elastic preloaded member, thereby enabling the second elastic preloaded member to apply a second force to the locking member.

[0013] In one embodiment of the present invention, the rotating end has a first supporting portion and a second supporting portion connected to each other, the minimum distance between the first supporting portion and the first rotating shaft is greater than the minimum distance between the second supporting portion and the first rotating shaft, and when the first supporting portion abuts against the locking piece, the locking piece is close to the clamping portion; when the second supporting portion abuts against the locking piece, the locking piece is away from the clamping portion.

[0014] Since the minimum distance between the first support portion and the first rotating shaft is greater than the minimum distance between the second support portion and the first rotating shaft, when the first support portion and the second support portion alternately contact the locking member, the locking member can move closer to or farther away from the clamping portion, thereby realizing quick replacement between the first connecting component and the second connecting component.

[0015] In one embodiment of the present invention, a sliding groove is provided on the limiting plate, the extending direction of the sliding groove is consistent with the moving direction of the locking member, and the locking member is provided with a sliding platform that cooperates with the sliding groove.

[0016] The sliding groove of the limiting plate cooperates with the sliding platform of the locking piece to achieve a sliding connection between the limiting plate and the locking piece, and plays a role in limiting the movement of the locking piece.

[0017] In one embodiment of the present invention, the clamping portion is a connecting rod provided on the adapter, and the locking member is provided with a locking hook that cooperates with the connecting rod, and the locking hook cooperates with the connecting rod to lock the first connecting component.

[0021] In one embodiment of the present invention, the first positioning portion is a positioning sleeve provided on the adapter, and the second positioning portion is a positioning pin provided on the limiting plate.

[0022] By configuring the first positioning portion as a positioning sleeve and configuring the second positioning portion as a positioning pin, the matching positioning sleeve and positioning pin can realize the positioning between the first connecting component and the second connecting component.

[0023] In one embodiment of the present invention, a limiting boss is provided on the limiting plate, and a limiting groove cooperating with the limiting boss is provided on the adapter.

[0024] By providing a limiting boss and a limiting groove, the relative position between the adapter and the limiting plate is further limited.

[0042] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments. The details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. The following embodiments and features therein may be combined with one another without conflict.

[0043] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The drawings only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0044] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0045] See Figures 1 to 4 , Figure 1 A quick-change structure is provided in one embodiment of the present invention, such as Figures 1 to 4 As shown, the quick-change structure includes a first connecting component and a second connecting component. It should be noted that the first connecting component is used to connect to the structural component that needs to be replaced on the production line, and the second connecting component is used to connect to the structural component that does not need to be replaced on the production line.

[0046] The first connecting component includes an adapter 1, which is provided with a first positioning portion 11 and a clamping portion 12. The second connecting component includes a stop plate 2, a locking member 3, and a handle 4. The stop plate 2 is provided with a second positioning portion 21 that cooperates with the first positioning portion 11. The cooperation between the first positioning portion 11 and the second positioning portion 21 achieves the positioning of the first connecting component on the second connecting component. The rotating end of the handle 4 is rotationally connected to the stop plate 2 and is rollingly connected to the locking member 3.

[0047] When the handle 4 is driven to rotate, the locking member 3 is slidably connected to the limiting plate 2. Driven by the handle 4, the locking member 3 slides closer to the clamping portion 12 to lock the first connecting member to the second connecting member, thereby enabling the installation of the structural member to be replaced; or, driven by the handle 4, the locking member 3 slides away from the clamping portion 12 to release the first connecting member from the second connecting member, thereby enabling the removal of the structural member to be replaced. The above-mentioned structure can realize the rapid installation and removal of structural members, which is beneficial to improving the changeover efficiency of the production line, and also conducive to improving the production stability of the production line, thereby facilitating the improvement of the production efficiency of the production line.

[0048] In some embodiments, the second connecting component further includes a connecting rod 5 and a first connecting shaft 22. The connecting rod 5 and the locking member 3 are rotationally connected via a second rotating shaft, and a limit bar hole 51 is provided on the connecting rod 5. The first connecting shaft 22 is disposed at the rotating end of the handle 4 and extends through the limit bar hole 51 of the connecting rod 5. When the handle 4 is rotated, the first connecting shaft 22 moves within the limit bar hole 51, thereby facilitating the movement of the locking member 3 by the handle 4.

[0049] In one example, the stopper bar hole 51 on the connecting rod 5 has a first end and a second end along its extension direction. When the first connecting shaft 22 moves between the first and second ends of the stopper bar hole 51, rotation of the handle 4 does not cause synchronous movement of the locking member 3. After the first connecting shaft 22 moves to the first or second end of the stopper bar hole 51, continued rotation of the handle 4 will drive the locking member 3 toward or away from the engaging portion 12, thereby locking or releasing the first connecting member.

[0050] In some embodiments, the second connecting component further includes a first elastic preload and a second elastic preload 6 that are arranged opposite to each other. The first elastic preload is located on the side of the rotating end of the handle 4 away from the locking member 3, and the second elastic preload 6 is located on the side of the locking member 3 away from the rotating end of the handle 4. When the handle 4 is rotated so that the locking member 3 approaches the clamping portion 12, both the first elastic preload 6 and the second elastic preload are compressed. At this time, the first elastic preload applies a first force toward the locking member 3 to the rotating end of the handle 4, and the second elastic preload 6 applies a second force toward the handle 4 to the locking member 3. Under the action of the first and second forces, the handle 4 and the locking member 3 will remain fixed in the absence of other external forces, which helps to ensure the stability of the connection between the first and second connecting components, and further helps to ensure the stability of production on the production line.

[0051] In one example, the second elastic preload member 6 always remains in a compressed state, so that the second elastic preload member 6 continuously applies a second force toward the handle 4 to the locking member 3, so that the locking member 3 always maintains a rolling connection with the handle 4.

[0052] See Figure 2 and Figure 5 In some embodiments, the second connecting component further includes a first rotating shaft 23, through which the handle 4 and the limiting plate 2 are rotationally connected. The limiting plate 2 has a receiving hole 24 for placing a first elastic preloaded member. The receiving hole 24 is in communication with the hole for mounting the first rotating shaft 23, so that the first elastic preloaded member can be pressed onto the first rotating shaft 23, and the first force applied by the first elastic preloaded member to the first rotating shaft 23 is transmitted to the handle 4 via the first rotating shaft 23, thereby achieving stability in the connection between the first connecting component and the second connecting component. It should be noted that a locking member is provided on the side of the receiving hole 24 away from the first rotating shaft 23 to confine the first elastic preloaded member within the receiving hole 24.

[0053] The limiting plate 2 also has a receiving groove 25 for placing the second elastic preload 6. The locking member 3 is located above the receiving groove 25 so that the locking member 3 is pressed on the second elastic preload 6, thereby enabling the second elastic preload 6 to apply a second force to the locking member 3.

[0054] Exemplarily, the first elastic preload member and the second elastic preload member 6 include but are not limited to elastic structural members such as springs and elastic members.

[0055] See Figure 2 and Figure 6In some embodiments, the rotating end of the handle 4 has a first support portion 41 and a second support portion 42 connected thereto. During the rotation of the handle 4, the first support portion 41 and the second support portion 42 alternately abut against the locking member 3. Furthermore, the minimum distance between the first support portion 41 and the first rotation axis 23 is greater than the minimum distance between the second support portion 42 and the first rotation axis 23.

[0056] When the first support portion 41 abuts the locking member 3, the locking member 3 approaches the engaging portion 12, thereby achieving the connection between the first and second connecting members. At this time, both the first and second elastic preload members 6 are compressed, thereby achieving the stability of the connection between the first and second connecting members.

[0057] When the second support portion 42 abuts the locking member 3, the locking member 3 moves away from the engaging portion 12, enabling the first and second connecting members to be disassembled. At this point, the first elastic preload member is uncompressed, while the second elastic preload member 6 is compressed and applies a second force to the locking member 3, facilitating the rotation of the auxiliary handle 4 and thus facilitating the disassembly of the first and second connecting members.

[0058] For example, the first support portion 41 can be configured as an arc structure. By configuring the arc structure, the contact area between the first support portion 41 and the locking member 3 is reduced, which helps to reduce the difficulty of matching between the handle 4 and the locking member 3, thereby helping to reduce processing costs. The second support portion 42 can be configured as a planar structure.

[0059] In one example, a guide portion 43 is provided between the first support portion 41 and the second support portion 42 of the handle 4 , and the guide portion 43 may be provided as an arc structure.

[0060] See Figure 2 、 Figure 5 and Figure 7 In some embodiments, to achieve a sliding connection between the locking member 3 and the limiting plate 2, a slide groove 26 is provided on the limiting plate 2, and a slide 31 is provided on the locking member 3 to cooperate with the slide groove 26. The extension direction of the slide groove 26 is consistent with the movement direction of the locking member 3. When the handle 4 is turned, the slide 31 moves within the slide groove 26 along the extension direction of the slide groove 26 to cooperate with the engaging portion 12 of the first connecting component.

[0061] Illustratively, the sliding groove 26 on the limiting plate 2 is communicated with the accommodating groove 25 .

[0062] In some embodiments, the clamping portion 12 is a connecting rod provided on the adapter 1, and the locking member 3 is provided with a locking hook 32 that cooperates with the connecting rod. The locking hook 32 cooperates with the connecting rod to complete the locking of the first connecting component.

[0063] For example, the locking hook 32 may be configured as an L-shaped structure. When the locking hook 32 is close to the connecting rod, the short side of the L-shaped structure hooks the connecting rod, thereby achieving cooperation between the locking hook 32 and the connecting rod.

[0064] In some embodiments, the handle 4 and the locking member 3 are both arranged in the middle of the limit plate 2, a clearance groove 13 is provided in the middle of the adapter 1, the lock hook 32 of the locking member 3 is located in the clearance groove 13, the connecting rod is passed through the clearance groove 13, and the lock hook 32 can move in the clearance groove 13 to approach or move away from the connecting rod, thereby realizing quick disassembly and assembly between the first connecting component and the second connecting component.

[0065] See Figure 2 In some embodiments, the first positioning portion 11 may be a positioning sleeve provided on the adapter 1, and the second positioning portion 21 may be a positioning pin provided on the limiting plate 2. When the positioning pin is inserted into the positioning sleeve, the first connecting component is positioned on the second connecting component. In other embodiments, the first positioning portion 11 may be a positioning hole provided on the adapter 1.

[0066] Exemplarily, at least three first positioning portions 11 and at least three second positioning portions 21 are provided to achieve positioning between the first connecting component and the second connecting component.

[0067] In some embodiments, in order to further limit the relative position between the adapter 1 and the limiting plate 2 , a limiting boss 27 is provided on the limiting plate 2 , and a limiting groove 14 cooperating with the limiting boss 27 is provided on the adapter 1 .

[0068] Exemplarily, the side wall where the limiting boss 27 and the limiting groove 14 meet is set to have an inclined angle to achieve a guiding effect during the cooperation between the two.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
