Description

Technical Field

[0001] The present application relates to the technical field of automobile parts production equipment, and in particular to an assembly tooling structure. Background Art

[0002] Cars have many parts, and assembling a single door or tailgate into a finished product often requires the coordination of dozens or even hundreds of components. Existing plastic tailgates, due to their unique structure and shape, are typically assembled in multiple steps. Each step requires different conditions for the tailgate. The tailgate's position needs to be adjusted for each subsequent step, and the tailgate's angle may even need to be flipped and adjusted during reassembly. This necessitates the development of multiple sets of tooling tailored to each process, resulting in high development costs. Furthermore, the tailgate needs to be repositioned each time the next step is switched. Repeated positioning wastes significant time in adjusting and moving the tailgate, and repeated positioning can also cause scratches on the tailgate's exterior. To achieve cost savings and efficiency gains, reduce development costs, and improve production efficiency, a new set of tooling for tailgate assembly is required. Utility Model Content

DETAILED DESCRIPTION

[0026] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0027] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0028] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0029] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0030] Reference Figure 1 and Figure 2 The upper structure 110 of the plastic tailgate 100 is an inclined slope, and the middle part of the slope is hollowed out to form a hollow structure for installing window glass. The inner side of the lower structure 120 of the plastic tailgate 100 is provided with a reinforcing structure to improve the structural rigidity. The lower structure 120 of the plastic tailgate 100 is capable of bearing loads.

[0031] The assembly tooling for transporting the plastic tailgate 100 of the present application is based on the above-mentioned situation of the plastic tailgate 100, optimizes the assembly tooling structure of the plastic tailgate 100, and redesigns the positioning or limiting structure for the plastic tailgate 100, so that the assembly tooling structure can adjust the posture angle of the plastic tailgate 100 according to different processes.

[0032] like Figure 3 As shown, the assembly tooling structure provided in the present application includes a frame 210, a rotating frame, and a locking mechanism 240, wherein the rotating frame is rotatably arranged on the frame 210 so that the rotating frame can rotate to a desired angle, and the locking mechanism 240 is used to limit the rotation of the rotating frame so as to fix the rotating frame to any desired angle.

[0033] Among them, the rotating frame includes a positioning assembly and a clamping assembly 260. The positioning assembly is used to position and support the outer surface of the plastic tailgate 100. The clamping assembly 260 includes a clamping piece 262. The clamping piece 262 can be flipped toward the positioning assembly to clamp the plastic tailgate 100 positioned on the positioning assembly.

[0034] During assembly of the plastic tailgate 100, the locking mechanism 240 is released, the rotating frame is rotated to an angle suitable for positioning the plastic tailgate 100, and then the locking mechanism 240 is locked in place. The positioning assembly positions the outer surface of the plastic tailgate 100 against the rotating frame. Once the plastic tailgate 100 is positioned, the pressing assembly 260 is activated, and the pressing member 262 rotates to press against the inner side of the plastic tailgate 100, pressing the plastic tailgate 100 against the positioning assembly. The corresponding assembly process can then begin.

[0035] When the assembly of one process is completed, the assembly tooling structure is pushed to the next process, and the rotation restriction of the rotating frame by the locking mechanism 240 is released. The operator can freely rotate the angle of the rotating frame according to the assembly requirements to adjust the angle posture of the plastic tailgate 100 to a state that meets the process. The rotating frame is then locked by the locking mechanism 240 to start the assembly of accessories for the next process.

[0036] Compared with the prior art, the tooling of the present application is simple in design and easy to operate. The angular posture of the positioned plastic tailgate 100 can be quickly adjusted through the cooperation of the rotating frame and the locking mechanism 240, so that the entire assembly tooling can be used in various processes, and there is no need to reposition the plastic tailgate 100 between processes. It only needs to be positioned once to be quickly assembled between various processes, effectively improving production efficiency and the turnover rate of the assembly tooling structure, and reducing the development cost of the assembly tooling structure.

[0037] In some embodiments, a receiving structure is provided between the two ends of the rotating frame, and positioning components arranged in the receiving structure form contoured positioning surfaces that adapt to the outer surface of the plastic tailgate 100. By providing a receiving space and arranging the positioning components for the plastic tailgate 100 within the receiving space according to the outer surface shape of the plastic tailgate 100, a contoured positioning surface that adapts to the outer surface shape of the plastic tailgate 100 is formed, ensuring accurate positioning. Furthermore, the provision of the receiving space allows the rotation center of the positioned and fixed plastic tailgate 100 to approach or coincide with the rotation center of the rotating frame, facilitating adjustment of the center of gravity of the rotating frame on which the plastic tailgate 100 is placed, and preventing the entire assembly tool from tipping over due to a shift in center of gravity during rotation.

[0038] In the embodiment of the present application, the rotating frame is placed horizontally, the rotation axis of the rotating frame is set horizontally, and the bottom of the accommodating space is offset from the rotation axis of the rotating frame. Of course, in some embodiments, the rotating frame can also be placed or set in other non-horizontal states.

[0039] In the embodiment of this application, Figures 3 to 5As shown, the rotating frame includes a mounting member 230, and the mounting member 230 includes a first frame body 231 and a second frame body 232 connected to each other. The connection position between the first frame body 231 and the second frame body 232 deviates from the rotation center axis of the rotating frame to form the above-mentioned accommodating structure. The rotation center axis of the rotating frame is located between the first frame body 231 and the second frame body 232.

[0040] The first frame 231 and the second frame 232 can be constructed and welded from square tubes or aluminum profiles, which can reduce the overall weight of the mounting member 230 and make rotation more labor-saving. Specifically, the angle formed between the first frame 231 and the second frame 232 is determined according to the angle formed between the upper structure 110 and the lower structure 120 of the plastic tail, which is not specifically limited here. The connection position between the first frame 231 and the second frame 232 deviates from the rotation center axis of the rotating frame, so that the rotation center of the positioned and fixed plastic tailgate 100 is close to or coincides with the rotation center of the rotating frame, which is beneficial for adjusting the center of gravity of the rotating frame on which the plastic tailgate 100 is placed, and facilitates subsequent rotation adjustment.

[0041] In some embodiments, such as Figure 4 and Figure 5 As shown, the positioning assembly includes a first positioning member 271, a second positioning member 272, a third positioning member 273 and a fourth positioning member 274. The first positioning member 271 is arranged on the first frame body 231, and the second positioning member 272 is arranged at the connection position between the first frame body 231 and the second frame body 232. The positioning surface of the first positioning member 271 cooperates with the positioning surface of the second positioning member 272 to form a first positioning reference that is adapted to the outer surface of the lower structural part of the plastic tailgate 100. The third positioning member 273 and the fourth positioning member 274 are arranged on the second frame body 232. The positioning surface of the third positioning member 273 and the positioning surface of the fourth positioning member 274 form a second positioning reference that is adapted to the outer surface of the upper structural part of the plastic tailgate 100. The first positioning reference and the second positioning reference form a contoured positioning surface.

[0042] Specifically, at least two first positioning members 271 are provided, and the positioning surface of the first positioning member 271 is adapted to the outer surface shape of the side of the lower structure 120 away from the upper structure 110. At least two second positioning members 272 are provided, and the positioning surface of the second positioning member 272 is adapted to the outer surface shape of the side of the lower structure 120 close to the upper structure 110; the first positioning reference formed by the combination of the positioning surface of the first positioning member 271 and the positioning surface of the second positioning member 272 clamps and positions the lower structure 120 of the plastic tailgate 100.

[0043] At least two third positioning members 273 are provided, and the positioning surface of the third positioning member 273 is adapted to the outer surface shape of the side of the upper structure 110 bordering the lower structure 120. At least two fourth positioning members 274 are provided, and the positioning surface of the fourth positioning member 274 is adapted to the outer surface shape of the side of the upper structure 110 away from the lower structure 120; the second positioning reference formed by the combination of the positioning surface of the third positioning member 273 and the positioning surface of the fourth positioning member 274 clamps and positions the upper structure 110 of the plastic tailgate 100.

[0044] In some specific embodiments, the first positioning member 271 and the second positioning member 272 are both close to the corners of the lower structure 120, and a clamping assembly 260 is arranged near the first positioning member 271 and the second positioning member 272. The clamping assembly 260 also includes a driving member 261 and a transmission member 263. The driving member 261 is rotatably arranged on the mounting member 230, and the transmission member 263 is rotatably arranged on the mounting member 230. One end of the transmission member 263 is rotatably connected to the driving end of the driving member 261, and the other end of the transmission member 263 is provided with a clamping member 262.

[0045] The driver 261 drives the pressing member 262 to flip via the transmission member 263, so that when the pressing operation is not in progress, the pressing assembly 260 does not interfere with the positioning of the plastic tailgate 100. The driver 261 can be a pneumatic cylinder or an electric push rod. The pressing member 262 is used to press against one side of the plastic tailgate 100 to provide a buffer layer. The buffer layer is made of an elastic material. Specifically, the buffer layer can be made of rubber, or a flexible material such as sponge or cloth. The provision of the buffer layer can reduce damage to the surface of the plastic tailgate 100 during the pressing process.

[0046] In some embodiments, such as Figures 6 and 7 As shown, the frame 210 includes two symmetrically arranged support members 212, which are arranged vertically. The two ends of the rotating frame are respectively rotatably connected to the two support members 212. The locking mechanism 240 is provided at the rotatable connection between the support members 212 and the rotating frame. The two support members 212 support the rotating frame on both sides, simplifying the structure used to support the rotating frame, avoiding excessive space occupied by too many parts, and providing more assembly space for operators, facilitating transfer and assembly. The simplified structure also reduces the manufacturing cost of the assembly tooling structure, reduces the overall weight of the assembly tooling structure, and facilitates movement and turnover.

[0047] In some embodiments, as Figure 6As shown, the rotating frame also includes a tilting member 220. Both ends of the tilting member 220 are rotatably connected to the support member 212 via a rotating shaft. The middle portion of the tilting member 220 is recessed away from the rotating frame's central axis to form a recessed structure. The mounting member 230 is detachably mounted in the recessed structure. Specifically, the mounting member 230 is secured to the recessed structure via bolts. The recessed structure facilitates adjustment of the rotating frame's center of gravity.

[0048] The flip member 220 includes a flip beam 221 and an extension arm 222. The extension arm 222 is provided on both sides of the flip beam 221. The extension arm 222 is provided on the support member 212 through a rotating shaft. In order to make the rotation smoother, a bearing is provided at the connection between the rotating shaft and the support member 212.

[0049] like Figure 7 and Figure 8 As shown, the locking mechanism 240 includes a first limiting member 241 and a second limiting member 242 . The first limiting member 241 is arranged at the rotation position of the rotating frame, and the second limiting member 242 is arranged on the support member 212 . The support member 212 can move to press against the first limiting member 241 .

[0050] In some specific embodiments, a locking mechanism 240 is provided on each of the two support members 212 , and the second limiting member 242 is fixed on the rotating shaft. The provision of the two locking mechanisms 240 makes the locking more reliable.

[0051] Furthermore, the surface of the second limiting member 242 is provided with a first tooth structure 2411, and the first limiting member 241 is provided with a second tooth structure 2421 that matches the first tooth structure 2411. The engagement of the first tooth structure 2411 and the second tooth structure 2421 achieves more reliable locking.

[0052] In the embodiment of the present application, the first limiting member 241 may be a gear, and the second limiting member 242 may be a rack.

[0053] The extension and retraction of the second limiting member 242 is achieved through a driving source 243 , which may be an air cylinder, an oil cylinder, or an electric push rod.

[0054] In some embodiments, the frame 210 also includes a connecting member 211, which serves as a reference for installation. The support member 212 is arranged on the connecting member 211, and the connecting member 211 is arranged in a horizontal direction. A reinforcement member is arranged between the connecting member 211 and the support member 212 to improve the structural rigidity of the support member 212. The bottom of the connecting member 211 is provided with rollers and support feet that can be telescopically adjusted so that the assembly tooling structure can be switched between fixed and mobile for easy turnover.

[0055] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
