Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0032] Example 1

[0033] In order to solve the problems existing in the prior art, the embodiments of the present application provide a positioning device for auxiliary assembly, such as Figure 1 As shown, it includes: a frame 1; at least one pair of body positioning mechanisms 2 symmetrically arranged on the frame 1 along the y direction of the frame 1, the body positioning mechanism 2 includes a body positioning portion 201 and a first adjusting component, the body positioning portion 201 is connected to the first adjusting component, and the body positioning portion 201 can adjust the position relative to the frame 1 along the x direction and / or the y direction through the first adjusting component; the body positioning portion 201 is arranged along the z direction, and is used to cooperate with the first tooling hole preset for connecting the body 9; at least one pair of front cover positioning mechanisms 3 symmetrically arranged on the frame 1 along the y direction, the front cover positioning mechanism 3 includes a front cover positioning portion 301 and a second adjusting component, the front cover positioning portion 301 is connected to the second adjusting component, and the front cover positioning portion 301 can adjust the position relative to the frame 1 along the x direction and / or the y direction through the second adjusting component; the front cover positioning portion 301 is arranged along the z direction, and is used to cooperate with the second tooling hole preset for connecting the front cover 10; wherein the x direction, the y direction and the z direction are directions in a Cartesian coordinate system, and the three directions correspond to the length, width and height directions of the body 9, respectively.

[0034] The frame 1 is the basic supporting structure of the entire positioning device, and is usually made of high-strength steel or other hard materials to ensure overall stability. The specific structure of the frame 1 is not limited, so as to be able to set the body positioning structure 2 and the front cover positioning mechanism 3, and can be placed on the body 9 without affecting the installation of the front cover 10. The body positioning part 201 and the front cover positioning part 301 can be structures such as pins or protrusions.

[0035] A pair of body positioning mechanisms 2 are symmetrically arranged along the y direction of the frame 1, and the body positioning part 201 is arranged along the z direction and extends into the first tooling hole symmetrically preset along the y direction of the body 9. In this way, the position of the body 9 in the x direction and the y direction can be determined, and the precise positioning of the frame 1 relative to the body 9 is achieved. Through the first adjustment component, the body positioning part 201 can be adjusted in the x direction and the y direction. This design adapts to different vehicle models or different assembly requirements and ensures the position accuracy between the frame 1 and the body 9.

[0036] A pair of front cover positioning mechanisms 3 are also symmetrically arranged along the y direction of the frame 1, and the front cover positioning part 301 is arranged along the z direction, and is used to extend into the second tooling hole symmetrically preset along the y direction of the front cover 10. The position of the front cover 10 in the x direction and the y direction can be determined, thereby achieving accurate positioning of the front cover 10 relative to the vehicle body 9. Through the second adjustment component, the front cover positioning part 301 can be adjusted in the x direction and the y direction. This ensures that the same positioning accuracy can be achieved each time the front cover 10 is assembled to the vehicle body 9 frame, that is, the relative position relationship between the front cover 10 and the vehicle body 9 frame remains consistent, avoiding large fluctuations or deviations.

[0037] The auxiliary assembly positioning device provided in the embodiment of the present application realizes accurate, stable and repeatable positioning of the vehicle body 9 and the front cover 10 during the assembly process through the design of the vehicle body positioning mechanism 2 and the front cover positioning mechanism 3. This not only improves the assembly efficiency, but also ensures the consistency and stability of product quality.

[0038] In some embodiments of the present application, the first adjustment component includes: a first positioning block 202, a second positioning block 203 and an adjustment pad 206; the first positioning block 202 is detachably connected to the second positioning block 203 in the y direction, and adjustment pads 206 of different numbers or different thicknesses are arranged between the first positioning block 202 and the second positioning block 203; the second positioning block 203 is detachably connected to the frame 1 in the x direction, and adjustment pads 206 of different numbers or different thicknesses are arranged between the second positioning block 203 and the frame 1; the body positioning part 201 is connected to the first positioning block 202.

[0039] The second positioning block 203 can be directly connected to the frame 1, or in order to match the structure of the vehicle body 9, the second positioning block 203 can be connected to the frame 1 through the first connecting block 205. Figure 2 and Figure 3As shown, the second positioning block 203 can be bolted to the first connection block 205 and the first positioning block 202, respectively. The adjustment pad 206 is located between the first positioning block 202 and the second positioning block 203 and between the second positioning block 203 and the frame 1. By removing the bolt fasteners, different numbers or thicknesses of adjustment pads can be selected between the first positioning block 202 and the second positioning block 203 and between the second positioning block 203 and the frame 1 as needed. By increasing or decreasing the number of adjustment pads or replacing adjustment pads of different thicknesses, the vehicle body positioning part 201 can be precisely fine-tuned in the x-direction and y-direction.

[0040] The first adjustment component can effectively solve the problem of inaccurate positioning caused by factors such as component manufacturing tolerance, assembly clearance, etc. When the position of the vehicle body positioning part 201 needs to be adjusted, only the adjustment pad 206 needs to be added, removed or replaced, without making major changes to the entire device, which is convenient and fast and improves the flexibility and accuracy of positioning.

[0041] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the first adjustment assembly further includes a third positioning block 204, which is connected to the first connecting block 205 and is used to support the vehicle body positioning portion 201 along the z direction. When the vehicle body positioning portion 201 is connected to the first tooling hole of the vehicle body 9, the third positioning block 204 can abut against the frame or other structural surface of the vehicle body 9, thereby providing a stable supporting force for the vehicle body positioning portion 201.

[0042] In some embodiments of the present application, the second adjustment component includes a group of slider assemblies 305 respectively arranged along the x-direction and the y-direction, and a group of slider assemblies 305 are slidably connected to each other. The front cover positioning portion 301 is slidably connected to one of the slider assemblies 305, and the front cover positioning portion 301 can realize bidirectional sliding adjustment in the x-direction and the y-direction through a group of slider assemblies 305.

[0043] By means of the slider assembly 305 arranged along the x-direction and the y-direction, the front cover positioning portion 301 can be conveniently and accurately moved on a two-dimensional plane to adapt to various size and shape changes, thereby ensuring perfect docking between the front cover 10 and the vehicle body 9 and greatly improving assembly accuracy and consistency.

[0044] Specifically, the second adjustment component also includes a fourth positioning block 302, a fifth positioning block 303, and a second connecting block 304. The front cover positioning portion 301 is connected to the fourth positioning block 302, and the fourth positioning block 302 is arranged on a slider of a slider assembly 305 arranged along the y direction, and the front cover positioning portion 301 can reciprocate along the y direction through the slider. The slider assembly 305 arranged along the y direction is connected to one end of the second connecting block 304, and the other end of the second connecting block 304 is connected to the slider of the slider assembly 305 arranged along the x direction. The slider assembly 305 arranged along the x direction is connected to the fifth positioning block 303, and the fifth positioning block 303 is fixedly connected to the frame, and the front cover positioning portion 301 can reciprocate along the x direction through the slider.

[0045] In some embodiments of the present application, the slider assembly 305 is composed of a slider and a slide rail, and the slider and the slide rail are precisely matched to achieve smooth sliding of the slider while maintaining high-precision positioning. The slider assembly 305 can be further equipped with a locking structure, which is used to firmly fix the slider in the selected position after the positioning adjustment is completed, to prevent the slider from accidentally moving due to vibration or other external forces during the actual assembly process, thereby maintaining the stability and accuracy of the front cover positioning part 301. The locking structure can be in various forms such as threaded locking, snap-on locking, butterfly nut locking, etc. For example, it may be a manual or automatic adjustment knob installed at the end of the slider or the slide rail, and by turning the knob, a spring can be compressed or a wedge can be pushed to press the slider to tighten it on the slide rail.

[0046] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the fourth positioning block 302 is connected to the second connecting block 304 through a slider assembly 305 arranged along the y direction, the second connecting block 304 and the fifth positioning block 303 are detachably connected in the x direction, the fifth positioning block 303 is connected to the frame 1, and adjustment gaskets of different quantities or thicknesses can be selected between the second connecting block 304 and the fifth positioning block 303 as needed, so that the front cover positioning part 301 can be accurately fine-tuned along the x direction.

[0047] The first adjustment component can also be connected in the manner of a slider component to adjust the position of the vehicle body positioning portion 201, and the second adjustment component can also be connected in the manner of an adjustment gasket to adjust the position of the front cover positioning portion 301. The specific structures of the first adjustment component and the second adjustment component can be determined according to the actual site environment.

[0048] In some embodiments of the present application, Figure 1As shown, the auxiliary assembly positioning device also includes at least one pair of support mechanisms 4 symmetrically arranged on the frame 1 along the y direction, and the support mechanism 4 includes a pair of first support blocks 401 and second support blocks 402 arranged along the z direction and in opposite directions. The first support blocks 401 and the second support blocks 402 are used to support the vehicle body 9 and the front cover 10, respectively.

[0049] The first support block 401 and the second support block 402 are arranged in the z direction, i.e., in a direction perpendicular to the surface of the vehicle body 9, and their directions are opposite, i.e., one up and one down. The first support block 401 and the second support block 402 correspond to different parts of the vehicle body 9 and the front cover 10, respectively, and are used to provide stable support from below and above during the assembly process to prevent the vehicle body 9 and the front cover 10 from tilting or deforming during assembly, especially to maintain balance and stability under the action of gravity. By providing up and down bidirectional support for the vehicle body 9 and the front cover 10, it is effectively ensured that during the assembly process, the vehicle body 9 and the front cover 10 can maintain the correct posture and position, avoid deformation or dislocation caused by their own weight, and improve the assembly accuracy.

[0050] In some embodiments of the present application, Figure 1 As shown, the frame 1 is sequentially provided with a first area, a second area and a third area along the x direction; a pair of vehicle body positioning mechanisms 2 are provided in the first area, a pair of front cover positioning mechanisms 3 are provided in the second area, and a pair of support mechanisms 4 are provided in the third area.

[0051] By distributing the body positioning mechanism 2, the front cover positioning mechanism 3 and the support mechanism 4 in different areas, the assembly process can be streamlined in the order of positioning first and then supporting, which effectively saves the time of workpiece transfer and positioning and improves production efficiency. Moreover, each area works independently without affecting each other. The body positioning mechanism 2 and the front cover positioning mechanism 3 can independently and accurately complete their respective positioning tasks, and the support mechanism 4 can ensure that the body 9 and the front cover 10 always maintain a stable support state during the assembly process, thereby ensuring the accuracy and quality of the final assembly to the greatest extent.

[0052] In some embodiments of the present application, Figures 1 to 3 As shown, the auxiliary assembly positioning device also includes at least one pair of fastening mechanisms 5, which are arranged on the frame 1 along the y direction relative to each other, and the fastening mechanisms 5 have nailing devices 505 for bolting the vehicle body 9 and the front cover 10.

[0053] The core component of the nailing device 505 can be a traditional bolt fastening structure, such as a ratchet wrench, etc., or an existing fastening technology such as an advanced electric nailing device can be used. It is used to firmly fix the body 9 and the front cover 10 together through bolt connection when the body 9 and the front cover 10 are correctly aligned. After the body 9 and the front cover 10 are accurately aligned through the positioning mechanism, the nailing device 505 can intervene in time and firmly connect the two through bolt connection to ensure the durability and stability of the assembly. The pre-set nailing device 505 simplifies the assembly steps, saves the time of temporarily finding suitable fasteners, and effectively speeds up the pace of assembly of the body 9 and the front cover 10.

[0054] In some embodiments of the present application, the fastening mechanism 5 also includes a third adjustment component, and the nailing device 505 is connected to the frame 1 through the third adjustment component. The nailing device 505 can adjust its position relative to the frame 1 along the x direction, y direction and z direction through the third adjustment component.

[0055] Specifically, Figure 2 and Figure 3 As shown, the third adjustment component includes a third connecting block 501, a sixth positioning block 502, a seventh positioning block 503, and an eighth positioning block 504. The third connecting block 501 is connected to the frame 1, and the sixth positioning block 502 is detachably connected to the third connecting block 501 in the x direction. Adjustment gaskets of different numbers or thicknesses are arranged between the sixth positioning block 502 and the third connecting block 501 as needed; the sixth positioning block 502 is detachably connected to the seventh positioning block 503 in the z direction, and adjustment gaskets of different numbers or thicknesses are arranged between the sixth positioning block 502 and the seventh positioning block 503 as needed; the seventh positioning block 503 is detachably connected to the eighth positioning block 504 in the y direction, and adjustment gaskets of different numbers or thicknesses are arranged between the seventh positioning block 503 and the eighth positioning block 504 as needed; the eighth positioning block 504 is connected to the nailing device 505, so as to realize flexible adjustment of the nailing device 505 in three directions: the x direction, the y direction, and the z direction. Through the third adjustment component, the nailing device 505 can be accurately adjusted according to the actual size and assembly position of the vehicle body 9 and the front cover 10, thereby ensuring that the bolts or nails are accurately driven into the predetermined position, greatly improving the assembly accuracy and efficiency.

[0056] In some embodiments of the present application, the fastening mechanism 5 further includes a floating device 506 , which is connected to the nailing device 505 along the z direction, and one end of the floating device 506 facing away from the nailing device 505 can reciprocate along the z direction.

[0057] Since the nailing device 505 may vibrate greatly along the z direction when working, such as the impact force generated during electric nailing or bolt tightening, the additional floating device 506 can effectively absorb this part of the vibration energy. When the nailing device 505 is subjected to vibration impact, the floating device 506 can make the nailing device 505 float up and down to a certain extent within a limited range, thereby alleviating the impact force during the tightening process, ensuring uniform tightening force, and avoiding the deviation of the tightening position due to excessive vibration or unnecessary damage to the vehicle body 9 and the front cover 10.

[0058] In some embodiments of the present application, the floating device 506 includes a telescopic rod and a spring arranged along the z direction, the telescopic rod is a hollow structure, the spring is arranged in the telescopic rod, and two ends of the spring are respectively connected to two ends of the telescopic rod.

[0059] The telescopic rod adopts a hollow structure, and a spring is contained inside. The two ends of the spring are respectively connected to the two ends of the telescopic rod, so that the floating device 506 forms a built-in spring-type buffer system. The telescopic rod can perform a certain range of telescopic movement in the z direction, and the built-in spring can effectively absorb and release the vibration or impact force from the nailing device 505 along the z direction when the telescopic rod is subjected to the vibration or impact force from the nailing device 505, thereby achieving floating support and shock absorption effect for the nailing device 505.

[0060] A flexible material, such as a rubber buffer pad, can be provided at one end of the telescopic rod facing away from the nailing device 505, so as to avoid that when the floating device 506 reciprocates in the z direction, if it comes into contact with the vehicle body 9, the rubber buffer pad can play a good buffering and anti-collision role, thereby avoiding direct hard collision to cause damage to the surface or internal structure of the vehicle body 9.

[0061] In some embodiments of the present application, Figures 1 to 3 As shown, a third support block 6 is provided at each position close to the fastening mechanism 5, and the third support block 6 is connected to the frame 1. The third support block 6 is used to support the position where the vehicle body 9 and the front cover 10 need to be connected. For example, when the front cover 10 and the vehicle body 9 are connected by two hinges, a third support block 6 is provided near the position where each hinge is located. During the assembly process, when the nailing device 505 begins to act on the hinge area, the third support block 6 can ensure that the hinge parts of the vehicle body 9 and the front cover 10 are fully and evenly supported during the fastening stage, thereby ensuring the stability of the assembly process and helping to improve the overall assembly quality and efficiency.

[0062] In some embodiments of the present application, Figure 1As shown, the auxiliary assembly positioning device also includes a pair of guide blocks 7 arranged on the frame 1 along the y direction. The guide blocks 7 are used to provide precise guide support for the front cover 10 during the assembly process, ensuring smooth docking along the preset path when moving forward and backward, reducing the position error during the assembly process, thereby improving the overall assembly accuracy. The structure of the guide block 7 can match the contour of the front cover 10.

[0063] In some embodiments of the present application, Figure 1 As shown, the auxiliary assembly positioning device also includes a pair of handles 8 arranged on the frame 1 along the y direction. By providing the handles 8, the operator can move, adjust and position the positioning device more intuitively and conveniently.

[0064] The use process of the auxiliary assembly positioning device provided in the embodiment of the present application is as follows:

[0065] The operator takes out the auxiliary assembly positioning device from a specific storage rack and then accurately installs it at the preset assembly position of the vehicle body 9, such as Figures 4 to 6 As shown. The worker places the matching nut on the nailing device 505 inside the auxiliary assembly positioning device in advance to prepare for the subsequent tightening operation. The front cover 10 is taken from the material supply rack and accurately placed on the properly installed auxiliary assembly positioning device to ensure that the front cover 10 is aligned with the vehicle body 9 in the initial stage. Afterwards, the worker uses the nailing device 505 to strictly tighten the front cover 10 to ensure that the bolts or nails can accurately and firmly connect the front cover 10 to the vehicle body 9. After all the tightening operations are completed, as shown in FIG.
