Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly testing equipment technology, and in particular to inspection tools for vehicle assembly. Background Technology

[0002] With the continuous development and popularization of vehicles, in order to adapt to the mass assembly of vehicles, quickly verifying whether the positioning accuracy of the assembly tooling meets the vehicle assembly accuracy requirements is one of the important ways to improve the efficiency and quality of mass assembly.

[0003] In the prior art, for the assembly fixture used to assemble the vehicle dashboard assembly, the number of inspection pieces is set according to the number of positioning points on the vehicle dashboard assembly, with the number of inspection pieces being the same as the number of positioning points, so that the assembly fixture can be inspected in one go. However, the inspection fixture used in the prior art is usually fixed to the base of the assembly fixture by a threaded connection. Since the installation and removal of the threaded connection is time-consuming and labor-intensive, when the assembly fixture needs maintenance, the inspection fixture and the assembly fixture are usually transported together to the maintenance area. Secondly, if the inspection fixture is repeatedly removed from the assembly fixture to be maintained and fixed to the assembly fixture that has not been maintained, the wear caused by the threaded connection will affect the inspection accuracy of the inspection fixture.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This utility model provides a vehicle assembly inspection tool, such as... Figure 1 and Figure 2 As shown, the vehicle assembly inspection fixture includes an inspection fixture bracket 1, at least two adjustment structures disposed on the inspection fixture bracket 1, and at least two inspection elements 2. The bottom of the inspection fixture bracket 1 is provided with a first insertion positioning part 11 extending along the height direction. At least two inspection elements 2 are correspondingly disposed at the output ends of at least two adjustment structures. Each adjustment structure can adjust the setting position of the corresponding inspection element 2. It can be understood that the number of inspection elements 2 is the same as the number of test positions on the structure to be inspected.

[0041] The vehicle assembly fixture has a first insertion positioning part 11 extending along the height direction at the bottom of the fixture bracket 1. When the setting position of the vehicle assembly fixture needs to be adjusted, the vehicle assembly fixture is lifted along the height direction of the fixture bracket 1 to separate the vehicle assembly fixture from the current installation position, and the first insertion positioning part 11 is inserted into the expected installation position along the height direction of the fixture bracket 1. This allows for quick and efficient adjustment of the setting position of the vehicle assembly fixture compared to the prior art, and enables the vehicle assembly fixture to be fully utilized, thereby reducing vehicle assembly costs.

[0042] Secondly, an adjustment structure is set on the fixture bracket 1 to adjust the setting position of each inspection piece 2. It can be understood that the setting position of any inspection piece 2 can be adjusted so as to effectively avoid the problem of reduced detection accuracy of the vehicle assembly fixture caused by frequent adjustment of the setting position of the vehicle assembly fixture and wear of the first insertion positioning part 11. This can effectively ensure the detection accuracy of the vehicle assembly fixture.

[0043] Secondly, an adjustment structure is set on the fixture bracket 1 to adjust the setting position of each inspection piece 2, so that the relative position between any two inspection pieces 2 can be adjusted, so that the vehicle assembly fixture can be adapted to the assembly of different vehicle models, thereby effectively improving the versatility of the vehicle assembly fixture.

[0044] Therefore, the vehicle assembly inspection tool has a simple structure, is easy to adjust and set, can effectively ensure the accuracy of inspection, and has good versatility.

[0045] Optionally, such as Figure 2As shown, the first insertion positioning part 11 is a first insertion post protruding along the height direction of the fixture bracket 1. Correspondingly, the structure to be inspected is provided with a first slot, and the first insertion post is inserted into the first slot. Further, the cross-section of the first insertion post along the axial direction is circular or non-circular, and the cross-section of the first slot along the axial direction is the same as the cross-section of the first insertion post along the axial direction. When the cross-section of the first insertion post along the axial direction is non-circular, the number of the first insertion positioning parts 11 is at least one. When the cross-section of the first insertion post along the axial direction is circular, the number of the first insertion positioning parts 11 is at least two. This allows for effective positioning of the relative position of the vehicle assembly fixture and the structure to be inspected, and enables quick and efficient adjustment of the setting position of the vehicle assembly fixture. Further, when the cross-section of the first insertion post along the axial direction is non-circular, the cross-section of the first insertion post along the axial direction is a square, rectangle, or other polygon. Further, the free end of the first insertion post is tapered, and along the height direction of the fixture bracket 1, the small end of the tapered shape is farther away from the fixture bracket 1 than the large end of the tapered shape. This facilitates the insertion and positioning of the first insertion post and improves its service life. Furthermore, the first insertion post is detachably connected to the bottom of the fixture bracket 1; or, the first insertion post is integrally formed on the bottom of the fixture bracket 1; or, the first insertion post is welded and fixed to the bottom of the fixture bracket 1. The detachable connection method is threaded connection or snap-fit, etc. Detachably connecting the first insertion post to the bottom of the fixture bracket 1 facilitates replacement of the first insertion positioning part 11 after wear. It is understood that the axial direction of the first insertion positioning part 11 is parallel to the height direction of the fixture bracket 1.

[0046] In other embodiments, the first insertion positioning part 11 is a second slot recessed along the height direction of the fixture bracket 1. Correspondingly, the structure to be inspected is provided with a second post, which is inserted into the second slot. Further, the cross-section of the second slot along the axial direction is circular or non-circular, and the cross-section of the second post along the axial direction is the same as the cross-section of the second slot along the axial direction. When the cross-section of the second slot along the axial direction is non-circular, the number of the first insertion positioning parts 11 is at least one. When the cross-section of the second slot along the axial direction is circular, the number of the first insertion positioning parts 11 is at least two. This allows for effective positioning of the relative position of the vehicle assembly fixture and the structure to be inspected, and enables quick and efficient adjustment of the setting position of the vehicle assembly fixture. Further, when the cross-section of the second slot along the axial direction is non-circular, the cross-section of the second slot along the axial direction is a square, rectangle, or other polygon. It is understood that the axial direction of the first insertion positioning part 11 is parallel to the height direction of the fixture bracket 1.

[0047] Optionally, such as Figure 1 and Figure 2As shown, a support block 12 protrudes from the bottom of the inspection fixture bracket 1. When the first insertion positioning part 11 is inserted and engaged with the structure to be inspected, the support block 12 supports the structure. Along the height direction of the inspection fixture bracket 1, the bottom surface of the support block 12 is completely in contact with the support surface of the structure to be inspected. This avoids problems such as poor stability of the inspection fixture bracket 1 due to unevenness at the bottom. Further, preferably, both the bottom surface of the support block 12 and the support surface of the structure to be inspected are planar. In other embodiments, the shape of the bottom surface of the support block 12 can be adaptively adjusted according to the specific shape of the support surface of the structure to be inspected. Further, the support block 12 is detachably connected to the bottom of the inspection fixture bracket 1; or, the support block 12 is integrally formed on the bottom of the inspection fixture bracket 1; or, the support block 12 is welded and fixed to the bottom of the inspection fixture bracket 1. The detachable connection method is threaded connection or snap-fit, etc.

[0048] In this embodiment, as Figure 1 and Figure 2 As shown, the first insertion positioning part 11 is a first insertion post, and the cross-section of the first insertion positioning part 11 along the axial direction is circular. There are two first insertion positioning parts 11. There are two support blocks 12.

[0049] Each adjustment structure includes a first adjustment structure 3.

[0050] Optionally, such as Figure 1-4 As shown, the first adjustment structure 3 includes a first adjustment part 31 disposed on the fixture bracket 1, a second adjustment part 32 detachably connected to the first adjustment part 31, and adjustment shims 33. The detection element 2 is disposed on the second adjustment part 32. Along a first direction, adjustment shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjustment part 31 and the second adjustment part 32; and / or, along a second direction, adjustment shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjustment part 31 and the second adjustment part 32; and / or, along the height direction of the fixture bracket 1, adjustment shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjustment part 31 and the second adjustment part 32. The first direction, the second direction, and the height direction of the fixture bracket 1 are perpendicular to each other. This arrangement allows for adjustment of the placement position of each detection element 2, adjustment of the relative position between any two detection elements 2, and avoidance of energy consumption. Figure 1 and Figure 2 In this context, the direction ab is the height direction of the fixture bracket 1; Figure 1 and Figure 2 The cd direction in the equation is the first direction; Figure 1 and Figure 2 The ef direction in the equation is the second direction.

[0051] like Figure 3 and Figure 4As shown, preferably, along the first direction, adjusting shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjusting part 31 and the second adjusting part 32; and along the second direction, adjusting shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjusting part 31 and the second adjusting part 32; and along the height direction of the fixture bracket 1, adjusting shims 33 of different numbers and / or thicknesses can be selectively clamped between the first adjusting part 31 and the second adjusting part 32. This is to effectively improve the accuracy of the setting position of the adjusting detection element 2.

[0052] When adjusting the setting position of the detection element 2 along the first direction, increase or decrease the number of adjusting shims 33 set between the first adjusting part 31 and the second adjusting part 32 along the first direction, and / or replace the adjusting shims 33 with different thicknesses; when adjusting the setting position of the detection element 2 along the second direction, increase or decrease the number of adjusting shims 33 set between the first adjusting part 31 and the second adjusting part 32 along the second direction, and / or replace the adjusting shims 33 with different thicknesses; when adjusting the setting position of the detection element 2 along the height direction of the fixture bracket 1, increase or decrease the number of adjusting shims 33 set between the first adjusting part 31 and the second adjusting part 32 along the height direction of the fixture bracket 1, and / or replace the adjusting shims 33 with different thicknesses.

[0053] Specifically, the first adjusting part 31 is provided with a first through hole, and the second adjusting part 32 is provided with a second through hole. The first adjusting structure 3 also includes a first bolt and a first nut. The first bolt passes through the second through hole and the first through hole and is threadedly connected to the first nut. The diameter of the first through hole is larger than the outer diameter of the threaded portion of the first bolt. Further, the first adjusting structure 3 also includes a mounting shim. The outer diameter of the mounting shim is larger than the diameter of the first through hole. The first bolt passes through the second through hole, the first through hole, and the mounting shim and is threadedly connected to the first nut; or, the outer diameter of the first nut is larger than the diameter of the first through hole. The first bolt passes through the second through hole and the first through hole and is threadedly connected to the first nut. This allows for the detachable connection of the first adjusting part 31 and the second adjusting part 32, and the setting position of the detection element 2 can be adjusted by increasing or decreasing the number of adjusting shims 33 or by replacing adjusting shims 33 of different thicknesses.

[0054] Specifically, in this embodiment, such as Figure 3 and Figure 4 As shown, both the first adjusting part 31 and the second adjusting part 32 are adjusting plates. In other embodiments, both the first adjusting part 31 and the second adjusting part 32 are adjusting blocks. Further, as... Figure 3 and Figure 4 As shown, the first adjustment part 31 is L-shaped, and the second adjustment part 32 is rectangular. This allows the second adjustment part 32 to move relative to the first adjustment part 31 along the first direction, the second direction, and the height direction of the fixture bracket 1.

[0055] In other embodiments, the adjustment structure is an electrically driven lifting and translation mechanism or a multi-axis robotic arm. The specific structures of the electrically driven lifting and translation mechanism and the multi-axis robotic arm are existing technologies and will not be described in detail here.

[0056] In other embodiments, the adjustment structure is a multi-degree-of-freedom slide rail slider structure. The specific structure of the multi-degree-of-freedom slide rail slider structure is prior art and will not be described in detail here.

[0057] Optionally, such as Figure 1-3 As shown, at least part of the adjustment structure also includes a second adjustment structure 4. The second adjustment structure 4 includes a linear slider 41. The fixed part 411 of the linear slider 41 is fixedly disposed on the fixture bracket 1, and the sliding part 412 of the linear slider 41 is slidably disposed on the fixed part 411. The first adjustment part 31 is fixedly disposed on the sliding part 412. It can be understood that the sliding direction of the sliding part 412 is a first direction, a second direction, the height direction of the fixture bracket 1, or any other orientation. This setting can further improve the accuracy of the setting position of the adjustment detection part 2; secondly, when the vehicle assembly fixture is used to assemble vehicles of different models, it can quickly and efficiently adjust the vehicle assembly fixture to adapt to the assembly of a specific vehicle model, improving the versatility of the vehicle assembly fixture. Further, the linear slider 41 is a first linear bearing, or the linear slider 41 is a single-degree-of-freedom slide rail slider structure, etc. The specific structure of the first linear bearing and the specific structure of the single-degree-of-freedom slide rail slider structure are both prior art, so they will not be described in detail here. The fixing part 411 is fixed to the fixture bracket 1 by means of threaded connection, welding or integral molding, etc.

[0058] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, in at least some of the adjustment structures, there are multiple first adjustment structures 3. This can effectively improve the working stability of the corresponding detection element 2.

[0059] In this embodiment, the structure to be inspected is exemplary, set as an assembly fixture for assembling a vehicle dashboard assembly. For example... Figure 1-4As shown, the vehicle assembly fixture includes four inspection components 2 and four adjustment structures, with each component corresponding to the others. The four adjustment structures are divided into two groups along the height of the fixture bracket 1, with two adjustment structures in each group spaced apart along a first direction. The two upper adjustment structures along the height of the fixture bracket 1 each include a second adjustment structure 4, where the linear sliding component 41 is a first linear bearing, and the sliding direction of the sliding part 412 is the first direction. The two lower adjustment structures along the height of the fixture bracket 1 each include two first adjustment structures 3. This allows for fine-tuning of the positions of the four inspection components 2, as well as significant adjustment of the two upper inspection components 2 moving closer or further apart along the first direction, making it suitable for assemblies of vehicle dashboards for different models. The specific structure of the assembly fixture for assembling vehicle dashboards is prior art and will not be described further here.

[0060] Specifically, such as Figure 1-3 As shown, the second adjustment structure 4 also includes a locking member 42, which can lock the relative positions of the fixed part 411 and the sliding part 412.

[0061] Optionally, such as Figure 1-3 As shown, the locking member 42 is a pin, the sliding part 412 is provided with a third through hole, and the fixing part 411 is provided with a plurality of fourth through holes spaced apart along the sliding direction of the sliding part 412. The pin is inserted into the third through hole and can be inserted into any of the fourth through holes. This allows the relative positions of the fixing part 411 and the sliding part 412 to be locked.

[0062] In other embodiments, the locking member 42 is a pin, the sliding part 412 is provided with a third through hole, and the fixing part 411 is provided with a plurality of threaded holes spaced apart along the sliding direction of the sliding part 412. The pin is inserted into the third through hole and can be threadedly connected to any of the threaded holes. This can also lock the relative position of the fixing part 411 and the sliding part 412.

[0063] In other embodiments, the locking member 42 includes a second bolt and a second nut, the sliding part 412 is provided with a third through hole, and the fixing part 411 is provided with a plurality of fourth through holes spaced apart along the sliding direction of the sliding part 412. The second bolt passes through the third through hole and one of the fourth through holes and is threadedly connected to the second nut. This also achieves locking of the relative position of the fixing part 411 and the sliding part 412.

[0064] It is understandable that other types of locking elements 42 can also be used, as long as they can lock the relative positions of the fixed part 411 and the sliding part 412.

[0065] Optionally, such as Figure 1-4As shown, the testing component 2 includes a connecting portion 21 fixedly disposed at the output end of the adjustment structure, and a second insertion positioning portion 22 slidably disposed on the connecting portion 21. Specifically, the connecting portion 21 is fixedly disposed on the second adjustment portion 32. It can be understood that the sliding direction of the second insertion positioning portion 22 is a first direction, a second direction, the height direction of the fixture bracket 1, or any other orientation. By using a sliding insertion method for testing, the efficiency of testing the structure under test can be effectively improved. After the setting position of the vehicle assembly fixture is fixed, the second insertion positioning portion 22 is inserted into the structure under test by sliding. If each second insertion positioning portion 22 can be inserted into the corresponding position on the structure under test, it indicates that the accuracy of the structure under test is qualified; if at least one second insertion positioning portion 22 cannot be inserted into the corresponding position on the structure under test, it indicates that the accuracy of the structure under test is unqualified. The fixed connection method is threaded connection, welding, or integral molding, etc.

[0066] In some embodiments, the second insertion positioning part 22 is a third insertion post extending along its own sliding direction. Correspondingly, a third slot is provided on the structure to be inspected, and the third insertion post is inserted into the third slot. Further, the shape of the cross-section of the third insertion post along the axial direction is the same as the shape of the cross-section of the third slot on the structure to be inspected along the axial direction.

[0067] In other embodiments, such as Figure 1-3 As shown, the free end of the second insertion positioning part 22 is recessed with a fourth slot along the sliding direction of the second insertion positioning part 22. Correspondingly, the structure under test is provided with a fourth post, which is inserted into the fourth slot. Further, the shape of the cross-section of the fourth slot along the axial direction is the same as the shape of the cross-section of the fourth post along the axial direction on the structure under test.

[0068] In this embodiment, taking the assembly tooling for assembling a vehicle dashboard assembly as an example, the sliding direction of the second insertion positioning part 22 is the second direction, and the free end of the second insertion positioning part 22 is recessed along the second direction with a fourth slot.

[0069] Preferably, such as Figure 3 and Figure 4 As shown, the connecting part 21 is provided with a stroke hole 211 extending along the sliding direction of the second insertion positioning part 22. The detection element 2 also includes a lever 23, which passes through the stroke hole 211 and is fixedly connected to the second insertion positioning part 22. This can limit the stroke of the second insertion positioning part 22 along its own sliding direction, preventing the second insertion positioning part 22 from disengaging from the connecting part 21. Secondly, the lever 23 facilitates the adjustment of the setting position of the second insertion positioning part 22 along its own sliding direction, making it convenient for the second insertion positioning part 22 to be inserted into or separated from the structure under test.

[0070] More preferably, such as Figure 3As shown, along the sliding direction of the second insertion positioning part 22, one or both ends of the travel hole 211 are provided with limiting holes 212. The limiting holes 212 communicate with the travel hole 211 and are distributed at an angle to the travel hole 211. The lever 23 can be at least partially accommodated in the limiting holes 212. This can limit the relative position of the connecting part 21 and the second insertion positioning part 22 along the sliding direction of the second insertion positioning part 22.

[0071] In some embodiments, the limiting hole 212 and the travel hole 211 are arranged at right angles. This provides a good limiting effect on the second insertion positioning part 22. In other embodiments, the limiting hole 212 and the travel hole 211 are arranged at an obtuse angle. In other embodiments, the limiting hole 212 and the travel hole 211 are arranged at an acute angle.

[0072] In this embodiment, as Figure 3 As shown, along the sliding direction of the second insertion positioning part 22, a limiting hole 212 is provided at one end of the stroke hole 211 away from the insertion positioning end of the second insertion positioning part 22; the limiting hole 212 is distributed at a right angle to the stroke hole 211. When the second insertion positioning part 22 is slid away from the structure to be inspected, the sliding lever 23 moves to one end of the limiting hole 212 away from the second insertion positioning part 22, and then rotates the lever 23 around the central axis of the second insertion positioning part 22 so that the lever 23 is partially accommodated in the limiting hole 212, thereby limiting the relative position of the connecting part 21 and the second insertion positioning part 22 along the sliding direction of the second insertion positioning part 22; when the structure to be inspected is detected by the second insertion positioning part 22, the lever 23 is rotated around the central axis of the second insertion positioning part 22 so that the lever 23 is located in the stroke hole 211, and then the second insertion positioning part 22 is slid closer to the structure to be inspected to determine whether the second insertion positioning part 22 can be inserted into the corresponding position on the structure to be inspected. In other embodiments, a limiting hole 212 is provided at one end of the travel hole 211 near the insertion positioning end of the second insertion positioning part 22 along the sliding direction of the second insertion positioning part 22. In other embodiments, limiting holes 212 are provided at both ends of the travel hole 211 along the sliding direction of the second insertion positioning part 22.

[0073] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, along the height direction of the fixture bracket 1, the two lower adjustment structures each include two first adjustment structures 3. The second adjustment part 32 of one first adjustment structure 3 is fixedly connected to the connecting part 21. The second adjustment part 32 of the other first adjustment structure 3 has a fifth through hole extending along the sliding direction of the second insertion positioning part 22. The second insertion positioning part 22 passes through the fifth through hole along its own sliding direction. In other embodiments, a second linear bearing is provided inside the fifth through hole. The outer ring of the second linear bearing is fixed to the inner circumferential wall of the fifth through hole, and the inner ring of the second linear bearing is fixedly sleeved on the outer circumference of the second insertion positioning part 22. This improves the smoothness of the sliding of the second insertion positioning part 22. The specific structure of the second linear bearing is prior art and will not be described further here.

[0074] Optionally, the fixture bracket 1 is made of aluminum alloy or carbon fiber. This improves the lightweight effect of the vehicle assembly fixture and further facilitates the handling and adjustment of the fixture's position. In other embodiments, the fixture bracket 1 may also be made of other materials such as titanium alloy.

[0075] Preferably, such as Figure 1 , Figure 2 and Figure 4 As shown, the fixture bracket 1 is equipped with a handling handle 13. This further facilitates the handling and adjustment of the fixture's position for vehicle assembly. It is understood that the position and number of handling handles 13 can be adjusted according to actual working conditions. The handling handles 13 are connected to the fixture bracket 1 by welding, threaded connections, or other methods.

[0076] Specifically, such as Figure 1 and Figure 2 As shown, the fixture support 1 includes a support base 14 and at least two uprights 15 fixedly mounted on the support base 14. Along the height direction of the fixture support 1, a first insertion positioning part 11 and a support block 12 are both located at the bottom of the support base 14. An adjustment structure is provided on the uprights 15. The fixing method includes welding, threaded connection, etc.

[0077] It is understandable that the extension direction of the upright 15 is parallel to the height direction of the fixture bracket 1.

[0078] Optionally, such as Figure 1-4 As shown, the fixture bracket 1 also includes a first reinforcing rod 16, and at least one first reinforcing rod 16 is fixedly installed between any two adjacent uprights 15. This improves the support stability and reliability of the uprights 15. The fixing methods include welding, threaded connection, etc.

[0079] Optionally, such as Figure 1-4As shown, the fixture bracket 1 also includes at least two second reinforcing rods 17, each corresponding to one of the at least two uprights 15. One end of each second reinforcing rod 17 is fixedly connected to an upright 15, and the other end is fixedly connected to the bracket base 14. This further enhances the support stability and reliability of the uprights 15. The fixing methods include welding, threaded connection, etc.

[0080] In this embodiment, as Figure 1 and Figure 2 As shown, two uprights 15 are arranged along the first direction, and each upright 15 is provided with two adjustment structures; a first reinforcing rod 16 is arranged between the two uprights 15.

[0081] In this embodiment, as Figure 1 and Figure 2 As shown, along the first direction, both uprights 15 are provided with handling handles 13 on their outer sides, and the support base 14 is also provided with handling handles 13 on both sides. This facilitates the handling and adjustment of the vehicle assembly fixtures in different external environments.
