Description

Technical Field

[0001] The present application relates to the technical field of automobile assembly, and in particular to a positioning tool for assembling vehicle parts. Background Art

[0002] When assembling a vehicle, due to factors such as assembly technology and overall design, gaps and surface differences are usually designed between various vehicle components, such as between doors and fenders, and between retractable side radar covers and fenders. Appropriate gaps can reduce wear and abnormal noise, and reasonable surface differences can make the overall lines of the vehicle smooth, coordinated and beautiful. Therefore, whether the gaps and surface differences between vehicle components meet the design standards will directly affect the use of the vehicle.

[0003] In the related art, when assembling two vehicle parts, an operator observes or uses a detection tool, such as a ruler, to detect whether the gap and surface difference between the two vehicle parts meet the requirements, and then another operator adjusts the position of one of the two parts relative to the other. Repeated measurements and adjustments are performed to complete the control of the gap and surface difference between the two.

[0004] However, when the gap and flushness of two vehicle components are controlled in the above manner to complete assembly, operation is inconvenient and assembly efficiency is low. Utility Model Content

The embodiments of the present application will be described in detail below with reference to the drawings.

Therefore, it should not be construed as a limitation to the present application.

[0042] The terms "first", "second", "third", "fourth", etc. in the description, claims and above-mentioned drawings of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0043] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0044] As described in the background art, in the related art, when assembling two vehicle components, for example, when assembling a telescopic side radar cover and a fender, the telescopic side radar cover needs to be embedded in the fender, and clearance surface differences are designed between the upper, lower, left and right sides adjacent to the fender of the telescopic side radar cover and the fender; and when assembling a door and a door frame, the door needs to be embedded in the door frame, and clearance surface differences are designed between the upper, lower, left and right sides adjacent to the door frame of the door and the door frame; by an operator observing or using a detection tool, such as a ruler, etc. to detect whether the clearance surface difference between the two vehicle components meets the requirements, and then another operator adjusts the position of one of the two components relative to the other, and such repeated measurement and adjustment are performed to complete the control of the clearance surface difference between the two.

[0045] However, when controlling the clearance surface difference between two vehicle components in the above manner to complete the assembly, it will result in inconvenient operation and low assembly efficiency.

[0046] In view of this, the present application provides a positioning tool for vehicle component assembly. By providing a contact member and a plurality of spacers, the plurality of spacers are all connected to the positioning surface of the contact member, and the spacers are arranged at intervals along the circumference of the contact member, so that the first side surfaces of the spacers and a part of the positioning surface jointly enclose a positioning area; by providing a vacuum suction member, the vacuum suction member is connected to the contact member.

[0047] Thus, when assembling the first vehicle component and the second vehicle component, the first vehicle component is placed in the positioning area, so that each first side surface and a part of the positioning surface are in contact with the first vehicle component to achieve full contact, which is beneficial to improving the structural stability; then the vacuum suction member and the second vehicle component are adsorbed, so that the second vehicle component is in a limited state relative to the first vehicle component for assembly, and the second vehicle component is in contact with the positioning surface and at least one of the second side surfaces of the spacers, so as to respectively control the surface difference and clearance between the first vehicle component and the second vehicle component through the positioning surface and the spacers; after the assembly is completed, the vacuum suction member is disengaged from the adsorption with the second vehicle component, so that the second vehicle component is in a movable state. The positioning tool for vehicle component assembly provided by the present application is convenient to operate and has high assembly efficiency.

[0048] Hereinafter, the present application will be described in detail with reference to the drawings and specific embodiments.

[0049] Refer to Figures 1 to 3 As shown in the figure, the positioning tool for vehicle component assembly provided by the present application includes a positioning assembly 100 and a vacuum suction member 200; the positioning assembly 100 includes a contact member 110 and a plurality of spacers 120. The contact member 110 has a positioning surface 111. The plurality of spacers 120 are all arranged on the positioning surface 111, and the spacers 120 are arranged at intervals in sequence along the circumference of the contact member 110. The spacer 120 has a first side surface 121 and a second side surface 122 which are oppositely arranged. The first side surfaces 121 and a part of the positioning surface 111 jointly enclose a positioning area 101. The positioning area 101 is used for placing the first vehicle component 600, and each first side surface 121 and a part of the positioning surface 111 are in contact with the first vehicle component 600; the vacuum suction member 200 is connected to the contact member 110. The vacuum suction member 200 is used for adsorbing or disengaging from the second vehicle component 700, so that the second vehicle component 700 can be switched between a limited state and a movable state relative to the first vehicle component 600. In the limited state, the second vehicle component 700 is in contact with the positioning surface 111 and at least one of the second side surfaces 122 of the spacers 120.

[0050] It should be noted that the first vehicle component 600 and the second vehicle component 700 in the embodiments of the present application are two components that need to be installed according to the specified clearance surface difference requirements during the vehicle assembly process. Exemplarily, the first vehicle component 600 can be a car door 800, and the second vehicle component 700 can be a fender 710 or a door frame (not shown in the figure); the first vehicle component 600 can be a telescopic side radar cover 610 or a car hood, and the second vehicle component 700 can be a fender 710.

[0051] It should also be noted that in order to enable the first vehicle component 600 to be more stably placed in the positioning area 101 jointly surrounded by the first side surfaces 121 and part of the positioning surfaces 111, the plurality of spacers 120 in the embodiments of the present application refer to at least four.

[0052] Specifically, the positioning surface 111 of the contact member 110 is used to provide a basic support for the assembly of the first vehicle component 600 and to ensure that there is a surface difference value required by the assembly design between the first vehicle component 600 and the second vehicle component 700; the spacer 120 is used to make there be a clearance value required by the assembly design between the first vehicle component 600 and the second vehicle component 700; by arranging the spacers 120 at intervals along the circumference of the contact member 110, the positioning area 101 jointly surrounded by the first side surfaces 121 and part of the positioning surfaces 111 matches the structure of the first vehicle component 600, provides a plurality of abutting points for the first vehicle component 600, avoids the shaking of the first vehicle component 600 during the assembly process, ensures the accurate alignment of the first vehicle component 600, and improves the reliability of the positioning installation.

[0053] The vacuum suction attachment 200 is used to adsorb the second vehicle component 700, so as to prevent relative movement between the two during the process of assembling the second vehicle component 700 and the first vehicle component 600, which is beneficial to improving the stability of controlling the clearance surface difference and ensuring the assembly accuracy. The vacuum suction attachment 200 can realize the rapid fixing and releasing of the second vehicle component 700, without additional fixing tools, simplifies the assembly process. In addition, the vacuum suction attachment 200 can be adapted to second vehicle components 700 of different materials, and has a wide application range.

[0054] In specific implementation, the positioning surface 111 of the contact member 110 can be designed accordingly according to the structures of the first vehicle component 600 and the second vehicle component 700 and the surface difference value required by the assembly design. Exemplarily, the size of the positioning surface 111 of the contact member 110 is larger than the size of the first vehicle component 600, and the spacers 120 are arranged at intervals along the circumference of the contact member 110 according to the structure of the first vehicle component 600, so that the positioning surface 111 is divided into Figure 2The first sub-positioning surface 1111 and the second sub-positioning surface 1112 are shown. Among them, the first side surface 121 of each spacer 120 and the first sub-positioning surface 1111 enclose a positioning area 101. The spacer 120 can be set as a rib or other structures, as long as the distance between the first side surface 121 and the second side surface 122 of the spacer 120 matches the clearance value. The embodiments of the present application do not limit this.

[0055] By setting the first sub-positioning surface 1111 to match the structure of the first vehicle component 600 to ensure sufficient contact between the two, and the second sub-positioning surface 1112 to match the structure of the second vehicle component 700 to ensure sufficient contact between the two; further, when the surface difference required for the assembly design of the first vehicle component 600 and the second vehicle component 700 is zero, it is set that the connecting line formed at the connection position of the first sub-positioning surface 1111 and the spacer 120 and the connecting line formed at the connection position of the second sub-positioning surface 1112 and the spacer 120 are located in the same plane. When the surface difference required for the assembly design of the first vehicle component 600 and the second vehicle component 700 is greater than zero, the two connecting lines are set to be staggered and located in different planes. With such a setting, the surface difference between the first vehicle component 600 and the second vehicle component 700 can be controlled more precisely.

[0056] The embodiments of the present application do not limit the specific structure of the contact member 110, as long as it has a positioning surface 111 that meets the above requirements. Exemplarily, the outer shape of the contact member 110 can be set as a regular rectangle, that is, as Figure 2 shown, so as to facilitate processing and manufacturing; in addition, on the basis of not affecting the function of the contact member 110, some structures other than the connection part with the spacer 120 can be omitted, so that the contact member 110 has an outer shape as Figure 6 shown, so that the structure of the contact member 110 is compact and occupies less space.

[0057] When using the positioning tooling to assemble the first vehicle component 600 and the second vehicle component 700, place the first vehicle component 600 in the positioning area 101 so that each first side surface 121 and part of the positioning surface 111, that is, the first sub-positioning surface 1111, are in contact with the first vehicle component 600 to achieve full contact, which is beneficial to improving the structural stability; by adsorbing the vacuum adsorber 200 and the second vehicle component 700, the second vehicle component 700 is in a limited state relative to the first vehicle component 600 for assembly, and the second vehicle component 700 is in contact with the second sub-positioning surface 1112 and at least one second side surface 122 of each spacer 120. Thus, the surface difference and clearance between the first vehicle component 600 and the second vehicle component 700 are respectively controlled by the positioning surface 111 and the spacer 120. When the second vehicle component 700 is in contact with multiple second side surfaces 122, the clearances in different directions between the first vehicle component 600 and the second vehicle component 700 can be controlled by using multiple spacers 120; after the assembly is completed, the vacuum adsorber 200 is detached from the second vehicle component 700, making the second vehicle component 700 in a movable state; overall, the operation is convenient and the assembly efficiency is high.

[0058] Exemplarily, as Figure 3 shown, the first vehicle component 600 is a telescopic side radar cover 610, and the second vehicle component 700 is a fender 710. Among them, the fender 710 has been pre-positioned and installed at the corresponding position of the vehicle, and a placement area 711 communicating with the interior of the vehicle is provided on the fender 710; the contact member 110, as Figure 2 shown, two spacers 120 are provided on both the upper and lower sides in the Y direction, and the two spacers 120 are spaced in the X direction. One spacer 120 is provided in the middle of the left and right sides of the contact member 110 in the X direction. It can be understood that the thickness of the spacers 120 provided on the left and right sides of the contact member 110 in the X direction and the thickness of the spacers 120 provided on the upper and lower sides of the contact member 110 in the Y direction may vary according to different clearance design values.

[0059] Combined with Figures 1 to 7, by placing the telescopic side radar cover 610 within the positioning area 101, the first side surfaces 121 and the first sub-positioning surfaces 1111 are brought into contact with the telescopic side radar cover 610. Then, when the two are placed on the placement area 711, the vacuum suction attachment 200 is used to adsorb onto the fender 710 to restrict the relative movement between the fender 710 and the telescopic side radar cover 610, that is, the fender 710 is in a limited position relative to the telescopic side radar cover 610. Overall, the contact member 110 is located on the side of the placement area 711, and the spacer members 120 and the telescopic side radar cover 610 are located within the placement area 711, so that the fender 710 comes into contact with the second side surfaces 122 and the second sub-positioning surfaces 1112. Then, the installation work of the telescopic side radar can be carried out. After the assembly is completed, the vacuum suction attachment 200 is disengaged from the adsorption with the second vehicle component 700.

[0060] Refer to Figure 1 , in some embodiments, the positioning tooling for vehicle component assembly further includes a connecting member 300; the connecting member 300 is connected to the side of the contact member 110 facing away from the positioning surface 111, and the vacuum suction attachment 200 is connected to the contact member 110 through the connecting member 300.

[0061] Specifically, by providing the connecting member 300, the reliable connection between the vacuum suction attachment 200 and the contact member 110 is ensured, reducing the displacement of components caused by vibration or impact during the assembly process, which is beneficial to improving the structural stability of the positioning tooling.

[0062] Connecting the side of the contact member 110 facing away from the positioning surface 111 to the vacuum suction attachment 200 through the connecting member 300 can avoid affecting the structure of the positioning surface 111, preventing interference with the positioning and surface difference control of vehicle components.

[0063] The present application embodiment does not limit the specific structure of the connecting member 300. Exemplarily, the connecting member 300 can be set as a plate-like structure, which has a simple structure and is convenient for production and processing.

[0064] Refer to Figure 1 and Figure 8 , in some examples, the vacuum suction attachment 200 is a flexible suction cup. The flexible suction cup is detachably connected to the connecting member 300. The flexible suction cup has a receiving cavity 220 with an opening 210 on one side, and the opening 210 faces away from the connecting member 300.

[0065] Specifically, the flexible suction cup can adapt to different shapes and surface characteristics of the second vehicle component 700. The structure of its receiving cavity 220 with an opening 210 on one side ensures good contact and sealing with the surface of the second vehicle component 700, and can maintain a stable adsorption force even on uneven or curved surfaces, improving the adaptability and versatility of the positioning tooling.

[0066] By designing the opening 210 to face away from the connecting member 300, the flexible suction cup can contact the vehicle component without obstruction, avoiding interference of the connecting member 300 with the adsorption effect. At the same time, it is also beneficial to the subsequent cleaning and inspection of the flexible suction cup, ensuring the cleanliness and adsorption efficiency of the adsorption surface.

[0067] In specific implementation, the flexible suction cup can be made of elastic materials such as rubber or silica gel, and the flexible suction cup is detachably connected to the connecting member 300. When the flexible suction cup is worn or damaged, it can be easily disassembled and replaced, and it is also convenient for regular cleaning of the suction cup, reducing the maintenance cost.

[0068] Refer to Figure 1 , in a specific example, the positioning tool for vehicle component assembly further includes a holding member 400. The holding member 400 is connected to the connecting member 300, and the holding member 400 and the flexible suction cup are located on opposite sides of the connecting member 300; the holding member 400 is used to push and press the flexible suction cup when the flexible suction cup contacts the second vehicle component 700, so as to form a negative pressure in the accommodation cavity 220 to adsorb the flexible suction cup on the second vehicle component 700.

[0069] In this way, the operator controls the adsorption and release of the flexible suction cup on the second vehicle component 700 by performing pressing or pushing and pulling actions through the holding member 400, and at the same time, the adsorption force can be adjusted by adjusting the magnitude of the pressing force; the connecting member 300 not only serves as a bridge between the flexible suction cup and the contact member 110, but also provides a fixed fulcrum for the holding member 400, simplifying the structure of the positioning tool.

[0070] In order to facilitate the operator to perform the adsorption operation of the vacuum adsorption component 200 on the second vehicle component 700, in other examples, the positioning tool for vehicle component assembly further includes a vacuum pump (not shown in the figure). The vacuum pump is communicated with the accommodation cavity 220; the vacuum pump is used to suck the accommodation cavity 220 to form a negative pressure in the accommodation cavity 220 when the flexible suction cup contacts the second vehicle component 700, so as to adsorb the flexible suction cup on the second vehicle component 700.

[0071] The vacuum pump is used to provide a stable and adjustable negative pressure source for the flexible suction cup, ensuring the reliability of the adsorption process.

[0072] In specific implementation, the vacuum pump can be connected to the accommodation cavity 220 through a pipeline to form an air flow path from the vacuum pump to the accommodation cavity 220. The operator starts the vacuum pump, and the vacuum pump sucks the air in the accommodation cavity 220 to form the negative pressure required for adsorption. At the same time, the air pressure in the accommodation cavity 220 can be restored relatively quickly during the release stage, facilitating the separation of the flexible suction cup, reducing the operation time, and being beneficial to improving the adsorption and release efficiency.

[0073] Refer to Figure 1, in a specific example, the number of vacuum suction members 200 is two. The connecting member 300 has opposite first end 310 and second end 320 in its extending direction. One of the two vacuum suction members 200 is connected to the first end 310, and the other is connected to the second end 320. The contact member 110 is located between the first end 310 and the second end 320.

[0074] Specifically, by respectively disposing the two vacuum suction members 200 at both ends of the connecting member 300, and using the two vacuum suction members 200 to adsorb to the second vehicle component 700, the adsorption force on the second vehicle component 700 can be increased, and the situation of inaccurate positioning caused by relative movement between the first vehicle component 600 and the second vehicle component 700 can be avoided.

[0075] Exemplarily, the extending direction of the connecting member 300 is the X direction as shown in Figure 1 . When connecting the connecting member 300 with the contact member 110, the first end 310 and the second end 320 are symmetrically arranged relative to the contact member 110. In this way, the stable state of the contact member 110 is facilitated by the adsorption forces of the two vacuum suction members 200 of equal magnitude, and the shaking and deviation during the assembly process are reduced.

[0076] Referring to Figure 5 , in some examples, the first side surface 121 includes a guiding section 1211 and an abutting section 1212 arranged in sequence. One end of the abutting section 1212 is connected to the guiding section 1211, and the other end of the abutting section 1212 is connected to the positioning surface 111.

[0077] Specifically, the guiding section 1211 is used to guide the first vehicle component 600 into the positioning area 101, ensuring that the first vehicle component 600 moves smoothly and accurately along the correct trajectory into the positioning area 101; the abutting section 1212 is used to provide a stable contact point for the first vehicle component 600, and by abutting against the first vehicle component 600, displacement of the first vehicle component 600 caused by vibration or external force is avoided, enhancing the stability of the first vehicle component 600 during the assembly process.

[0078] In specific implementation, the shape and size of the guiding section 1211 can be set according to the structure of the first vehicle component 600. Exemplarily, the first vehicle component 600 is provided with an arc-shaped outer end, and the guiding section 1211 is a chamfer matching the arc of the outer end.

[0079] In some embodiments, anti-scratch layers (not shown in the figure) are provided on the first side surface 121, the second side surface 122, and the positioning surface 111.

[0080] Thus, the scratch-resistant layer can prevent scratches or abrasions on the surface of vehicle components during the assembly process, maintaining aesthetics and integrity. Among them, the scratch-resistant layer on the first side 121 ensures that the first vehicle component 600 will not be damaged due to friction when entering the positioning area 101; the scratch-resistant layer on the second side 122 can prevent scratches on the surface of the second vehicle component 700 when the second vehicle component 700 is in contact with it and in a limited position state, keeping the surface of the component intact; the scratch-resistant layer on the positioning surface 111 ensures that the first vehicle component 600 and the second vehicle component 700 will not be damaged when contacting the positioning surface 111, and at the same time helps to reduce the positioning error caused by friction during the positioning process and improve the positioning accuracy.

[0081] In specific implementation, the scratch-resistant layer can be made of wear-resistant materials with a low friction coefficient, such as silicone, resin, or flocked cloth.

[0082] Continue to refer to Figure 1 , in some embodiments, the positioning tooling for vehicle component assembly further includes a fixing component 500. The fixing component 500 includes a first fixing member 510 and a second fixing member 520. The flexible suction cup is detachably connected to the connecting member 300 through the first fixing member 510, and the holding member 400 is detachably connected to the connecting member 300 through the second fixing member 520.

[0083] The first fixing member 510 is used to ensure a stable connection between the flexible suction cup and the connecting member 300. At the same time, the position of the flexible suction cup can be adjusted or different specifications of suction cups can be replaced according to needs, simplifying the maintenance and replacement process.

[0084] The second fixing member 520 is used to connect the holding member 400 and the connecting member 300, ensuring the stability of the holding member 400 during operation. At the same time, it is also convenient to adjust the position or replace the holding member 400 to meet different operation requirements.

[0085] In specific implementation, the first fixing member 510 can be set as a first screw, and the second fixing member 520 can be set as a second screw. The flexible suction cup includes a suction cup body and a mounting member connected to the suction cup body; by opening a first through hole and a second threaded hole on the connecting member 300, a first threaded hole on the mounting member, and a second through hole on the holding member 400, when assembling the positioning tooling, the first screw is passed through the first through hole and connected to the first threaded hole, and the second screw is passed through the second through hole and connected to the second threaded hole to complete the connection between the flexible suction cup and the connecting member 300, and the connection between the holding member 400 and the connecting member 300.

[0086] In a specific example, the contact member 110 and each spacer 120 are integrally formed.

[0087] Specifically, the one-piece forming process refers to the process of forming the entire component in one go within a single mold. Compared with the traditional step-by-step manufacturing process, one-piece forming can simplify the manufacturing process, and it has high precision, high production efficiency, and low production costs.

[0088] The contact member 110 and each spacer 120 are integrally formed, which can avoid the problem of loose connection between the two, and prevent the occurrence of gaps between the two, which may affect the structural strength of the positioning assembly 100.

[0089] Furthermore, the use of one-piece forming can avoid the connection and additional processing between the contact member 110 and each spacer 120, which is conducive to improving production efficiency and reducing production costs.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
