[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following is for reference. Figures 1-6 A lifting and positioning device 100 according to an embodiment of the first aspect of the present invention is described.

[0034] like Figure 1 As shown, the lifting and positioning device 100 according to a first aspect embodiment of the present invention includes: a support 1, a movable positioning component 2, a first driving component 3, a locking component 4, and a reinforcing rib 8.

[0035] Specifically, the movable positioning component 2 is located on the support 1, and the movable positioning component 2 can be positioned vertically (e.g., Figure 1The movable positioning assembly 2 can be used to position the vehicle body, for example, the movable positioning assembly 2 can include positioning columns used to position the vehicle body parts during assembly or processing. The first driving member 3 is in driving connection with the movable positioning assembly 2 to drive the movable positioning assembly 2 to move in the vertical direction, for example, the first driving member 3 can be a driving cylinder. The locking assembly 4 is arranged on the support 1 and is adapted to lock the movable positioning assembly 2 when the movable positioning assembly 2 positions the vehicle body. The reinforcing rib plate 8 is arranged on the side of the support 1 away from the movable positioning assembly 2 and extends in the vertical direction.

[0036] For example Figure 1 As shown in the figure, the support 1 can include a base 13 and a support plate 14, wherein the base 13 is formed in a block shape, the support plate 14 is arranged on the upper side of the base 13 and extends in the vertical direction, the reinforcing rib plate 8 is arranged on the rear side of the support plate 14, the bottom end of the reinforcing rib plate 8 is connected with the base 13, the other end of the reinforcing rib plate 8 extends in the vertical direction, and the reinforcing rib plate 8 can improve the structural strength and stability of the support 1. The movable positioning assembly 2 is arranged on the front side of the support plate 14 and is in movable connection with the support plate 14, the movable positioning assembly 2 can move in the vertical direction relative to the support plate 14, the first driving member 3 is a driving cylinder, the piston of the first driving member 3 moves in the vertical direction, and the top end of the piston can be connected with the movable positioning assembly 2 through a movable pin to drive the movable positioning assembly 2 to move in the vertical direction. When the movable positioning assembly 2 supports and positions the vehicle body, the locking assembly 4 interferes with the movable positioning assembly 2 on the moving path of the movable positioning assembly 2 to block the movable positioning assembly 2, so as to ensure that the movable positioning assembly 2 does not move under the pressure of the positioned parts, thereby improving the stability of the vehicle body parts during assembly or processing.

[0037] The lifting positioning device 100 according to the embodiment of the present application can adapt to the positioning of different vehicle models and different height parts of the vehicle body by arranging the movable positioning assembly 2 to move in the vertical direction relative to the support 1, and the locking assembly 4 can make the support and positioning of the vehicle body by the lifting positioning device 100 more stable, thereby being beneficial to improving the assembly efficiency and assembly precision of the vehicle.

[0038] In some embodiments, the height of the locking assembly 4 on the support 1 is adjustable to adapt to the locking problem of the movable positioning assembly 2 during positioning of different vehicle models or different parts, or the movable positioning assembly 2 can have multiple locking parts with different heights, and when the movable positioning assembly 2 is at different heights, the locking assembly 4 can cooperate with the corresponding locking part to realize the locking of the movable positioning assembly 2 at different heights.

[0039] According to some embodiments of the present invention, the first driving member 3 can be connected to the support 1, thereby ensuring the stability of the first driving member 3 when driving the movable positioning component 2. For example Figure 1 As shown, a clamping assembly 7 may be provided on the support 1. The clamping assembly 7 is adapted to clamp the first driving member 3. The clamping assembly 7 includes a fixed plate 71 and a clamping block 72 arranged opposite to each other. The fixed plate 71 is connected to the support 1. The clamping block 72 extends along the circumference of the first driving member 3. The clamping block 72 defines a clamping groove that is adapted to the peripheral wall of the first driving member 3. The open end of the clamping block 72 is connected to the fixed plate 71 by screws. The first driving member 3 is located in the clamping groove. In this way, the connection stability between the first driving member 3 and the support 1 can be improved.

[0040] refer to Figure 1 and Figure 2 The movable positioning component 2 may include a movable plate 21 and a positioning element 22. The movable plate 21 and the support 1 can be positioned along the thickness direction (e.g., ...). Figure 1 The movable plate 21 is arranged in a stacked manner (in the front-to-back direction as shown in the diagram) and is driven by the first driving member 3. The movable plate 21 is adapted to move vertically under the drive of the first driving member 3 to achieve lifting and lowering. The positioning member 22 is provided on the top of the movable plate 21 to position the vehicle body. The positioning member 22 can be formed as a positioning post. Multiple positioning members 22 can be provided and spaced apart on the top of the movable plate 21. Optionally, the arrangement of multiple positioning members 22 can be set according to the structure of the positioned component. The locking assembly 4 may include a second driving member 41 and a locking block 42. The second driving member 41 is provided on the support 1, and the locking block 42 is driven by the second driving member 41. The locking block 42 is adapted to move under the drive of the second driving member 41 to lock or unlock the movable plate 21. In this way, the locking assembly 4 can better lock the movable positioning assembly 2 to ensure the stability of the movable positioning assembly 2 during operation.

[0041] Furthermore, the second driving member 41 is adapted to drive the locking block 42 to move between the locked position and the unlocked position. In the locked position, the locking block 42 and the movable plate 21 interfere with each other on the moving path of the movable plate 21. In the unlocked position, the locking block 42 exits the moving path of the movable plate 21. In this way, the movement form of the locking block 42 is simple, which is conducive to simplifying the overall control program.

[0042] For example, in the locked position, the locking block 42 can be supported on the lower side of the movable plate 21 to prevent the movable plate 21 from moving downward under the pressure of the vehicle body. In the unlocked position, the locking block 42 is no longer interfering with the movable plate 21, and the movable plate 21 can move freely in the vertical direction under the drive of the first driving member 3 to adjust its position on the support 1. Alternatively, a slot extending along the thickness direction can be provided on the movable plate 21, and the locking block 42 can be pulled out and fitted into the slot. When the movable plate 21 is in a position suitable for positioning the vehicle body, the locking block 42 can be inserted into the slot. After the vehicle body assembly is completed, the locking block 42 can be removed from the slot. Of course, the present invention is not limited to this; the locking block 42 and the movable plate 21 can also be engaged by snap-fit ​​or other methods.

[0043] In some embodiments, the second driving member 41 is adapted to drive the locking block 42 to rotate between the locked position and the unlocked position. For example, the angle between the line connecting the locking position and the rotation center of the locking block 42 and the line connecting the unlocked position and the rotation center of the locking block 42 can be 90 degrees. It can be that the locking position and the unlocked position each form a 90-degree angle with the rotation center line of the locking block 42 in the horizontal plane, or that the locking position and the unlocked position each form a 90-degree angle with the rotation center line of the locking block 42 in the vertical plane. Of course, the angle between the line connecting the locking position and the rotation center of the locking block 42 and the line connecting the unlocked position and the rotation center of the second driving member 41 can be reasonably selected according to actual needs. At this time, the second driving component 41 can be a self-locking cylinder. When the second driving component 41 drives the locking block 42 to rotate to the locked position, the second driving component 41 achieves air cut-off self-locking, and the locking block 42 cannot move, thereby locking the movable plate 21. After the vehicle body assembly is completed, the second driving component 41 restarts the air supply and drives the locking block 42 back to the unlocked position, so that the movable plate 21 can move.

[0044] Alternatively, the second driving member 41 is adapted to drive the locking block 42 to extend and retract between the locked and unlocked positions along the thickness direction of the movable plate 21, with the thickness direction perpendicular to the vertical direction. In other words, the second driving member 41 can drive the locking block 42 to reciprocate linearly along a direction perpendicular to the moving direction of the movable plate 21. In this case, the second driving member 41 can be a telescopic cylinder, which makes the movement of the locking block 42 simpler and easier to manufacture and assemble.

[0045] Furthermore, the movable plate 21 and the second driving member 41 are respectively located on the support 1 along the thickness direction (e.g., Figure 1 On both sides (in the front-back direction shown), the support 1 has a through-hole 11 formed along the thickness direction. The through-hole 11 is used to avoid the locking block 42 when it moves. For example, Figure 1As shown, the movable plate 21 is located on the front side of the support 1, the second driving member 41 is located on the rear side of the support 1, and the clearance opening 11 can penetrate the support 1 in the front-back direction. In this way, the locking block 42 can be inserted into the clearance opening 11 during the movement, which can simplify and shorten the movement path of the locking block 42, thereby helping to further simplify the overall structure of the lifting and positioning device 100.

[0046] According to some embodiments of the present invention, one of the support 1 and the movable plate 21 is provided with a slide rail 12 extending in a vertical direction, and the other is provided with a slider adapted to slide with the slide rail 12. For example, the support 1 may be provided with a slide rail 12 extending in a vertical direction, and the movable plate 21 may be provided with a slider (not shown in the figure) on the side facing the support 1. Alternatively, the movable plate 21 may be provided with a slide rail 12 extending in a vertical direction on the side facing the support 1, and the support 1 may be provided with a slider. When the first driving member 3 drives the movable plate 21 to move in a vertical direction, the slider can slide relative to the slide rail 12. In this way, the sliding cooperation between the slide rail 12 and the slider can improve the stability of the movable plate 21 during movement and also help to improve the positioning accuracy.

[0047] In some embodiments, the lifting and positioning device 100 may further include a first limiting member 5 and a second limiting member 6. Both the first limiting member 5 and the second limiting member 6 are disposed on the side of the support 1 facing the movable plate 21, and the first limiting member 5 and the second limiting member 6 are arranged at intervals in the vertical direction. The movable positioning assembly 2 is adapted to move vertically between the first limiting member 5 and the second limiting member 6. For example... Figure 3 As shown, the first limiting member 5 and the second limiting member 6 define the movement range of the movable positioning component 2. The first limiting member 5 is located on the upper side of the movable plate 21 and determines the upper limit position of the movable plate 21. The second limiting member 6 is located on the lower side of the movable plate 21 and determines the lower limit position of the movable plate 21. When the movable plate 21 moves to the upper limit position, it abuts against the first limiting member 5. When the movable plate 21 descends to the lower limit position, it abuts against the second limiting member 6. In this way, the movable positioning component 2 can be prevented from exceeding the movement range, avoiding damage to the lifting positioning device 100 and further improving the reliability of the lifting positioning device 100.

[0048] Furthermore, the movable positioning component 2 may include a movable plate 21, which is connected to the first driving member 3. The movable plate 21 is adapted to move vertically under the drive of the first driving member 3. The movable positioning component 2 may include a first limiting engagement member 23 and a second limiting engagement member 24. The first limiting engagement member 23 is located on the upper part of the movable plate 21 and is adapted to engage with the first limiting member 5, for example, in an abutting engagement, when the movable plate 21 moves upward to the upper limiting position. The second limiting engagement member 24 is located on the lower part of the movable plate 21 and is adapted to engage with the second limiting member 6, for example, in an abutting engagement, when the movable plate 21 moves downward to the lower limiting position. In this way, the movable plate 21 can be limited, and the overall structure is simple and easy to assemble.

[0049] According to some embodiments of the present invention, reference Figure 1 and Figure 3 The first limiting member 5 may include: a first connecting arm 51 and a first limiting post 52, wherein the first connecting arm 51 extends in the front-rear direction, the rear end of the first connecting arm 51 is connected to the top of the support 1, the front end of the first connecting arm 51 extends toward the movable plate 21 and is located on the front side of the movable plate 21, the first limiting post 52 is disposed at the front end of the first connecting arm 51 and extends in the vertical direction, and the first limiting mating member 23 is formed as a limiting block, the limiting block is disposed on the front side of the movable plate 21 and is arranged opposite to the first limiting post 52 in the moving direction of the movable plate 21. The second limiting member 6 may include: a second connecting arm 61 and a second limiting post 62, wherein the rear end of the second connecting arm 61 is connected to the front surface of the support 1, the front end of the second connecting arm 61 extends to the front side of the movable plate 21, the second limiting post 62 is disposed at the front end of the second connecting arm 61 and extends in the vertical direction, and the second limiting fitting member 24 is formed as a limiting block, which is disposed at the lower part of the front side of the movable plate 21 and is arranged opposite to the second limiting post 62 in the moving direction of the movable plate 21. In this way, the movable plate 21 can be limited, and the overall structure is simple and easy to assemble.

[0050] In a specific example, the first limiting post 52 can be threadedly engaged with the first connecting arm 51, and the second limiting post 62 can be threadedly engaged with the second connecting arm 61, thereby enabling the first limiting post 52 and the second limiting post 62 to move up and down, so as to adjust the movement range of the movable positioning component 2, so as to better meet the positioning application range of the lifting positioning device 100 for different vehicle models and different parts of the vehicle body.

[0051] Furthermore, refer to Figure 1 and Figure 3The first limiting fitting 23 and the second limiting fitting 24 are both located on the side of the movable plate 21 facing away from the support 1. The movable plate 21 also has a clearance groove 211, which extends vertically and penetrates the top wall of the movable plate 21. The first limiting fitting 23 is located on the lower side of the clearance groove 211 and adjacent to the clearance groove 211. The width of the first connecting arm 51 is adapted to the width of the clearance groove 211. When the movable plate 21 moves vertically, the first connecting arm 51 is located in the clearance groove 211. In this way, on the one hand, it can avoid increasing the overall height of the support 1 to ensure that the movable plate 21 has a large range of motion when the clearance groove 211 is not provided on the movable plate 21, thereby increasing the volume of the lifting and positioning device 100. On the other hand, the cooperation between the first connecting arm 51 and the clearance groove 211 also helps to avoid the phenomenon of the movable plate 21 shaking when it moves to a certain extent, so as to better assist the slider mechanism of the slide rail 12 to improve the stability of the movable plate 21 when it moves.
