Description

Technical Field

[0001] This utility model relates to the field of automotive hinge assembly technology, and in particular to an automotive hinge assembly angle adjustment tool. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are most commonly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges have emerged, characterized by a buffering function when the door closes, minimizing noise from the door colliding with the cabinet. In automotive manufacturing, hinges are typically assembled at the door.

[0003] However, in the existing technology, when assembling the hinges of existing car doors, the car door is usually fixed first, and then the hinges are assembled on one side of the door. However, most car door hinge assembly fixtures can only fix doors of the same model when fixing them, and cannot clamp and fix them according to different models and sizes of car doors, resulting in a limited range of applications. Moreover, the angle of the door cannot be adjusted according to the assembly requirements, which is inconvenient for people to use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tooling for adjusting the assembly angle of automotive hinges.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for adjusting the assembly angle of an automotive hinge, comprising: a base plate and a main frame, a fixing structure being provided on the top of the base plate, an adjusting structure being provided between the base plate and the main frame, the fixing structure comprising two bases, a bidirectional screw being rotatably mounted on the inner side of the bases, and movable blocks being threadedly connected to the outer sides of the bidirectional screws near both ends, a placement plate being fixedly mounted on the top of each of the two movable blocks, a fixing block being fixedly mounted on one side of each of the two placement plates, a pressure block being slidably mounted on one side of each fixing block, an L-shaped frame being fixedly mounted on the top of the base, a hydraulic rod being fixedly mounted on the top of the L-shaped frame, a movable frame being fixedly mounted through the bottom end of the hydraulic rod through the L-shaped frame, two T-shaped sliding plates being provided on the inner side of the movable frame, connecting rods being fixedly mounted on the bottom of each of the two T-shaped sliding plates, and the bottom ends of the two connecting rods respectively penetrating the tops of the two fixing blocks and being fixedly connected to the two pressure blocks respectively.

[0006] In a preferred embodiment, the top of the base is provided with a first sliding groove, and the two movable blocks are disposed inside the first sliding groove and slide in contact with the base. The bottom of the movable frame is provided with a T-shaped sliding groove, and the two T-shaped sliding plates are disposed inside the T-shaped sliding groove and slide in contact with the movable frame.

[0007] In a preferred embodiment, two guide rods are fixedly installed between the L-shaped frame and the base, and both guide rods pass through the movable frame and slide in contact with the movable frame.

[0008] In a preferred embodiment, a gear is rotatably mounted on the inner side of the main frame, and two racks are meshed with the outer side of the gear. A connecting block is fixedly mounted on the top of each of the two racks. Two rectangular sliding grooves are opened on the top of the main frame, and the two connecting blocks are respectively disposed inside the two rectangular sliding grooves and slide in contact with the main frame.

[0009] In a preferred embodiment, the two connecting blocks are respectively fixedly connected to the two bases. A first motor is fixedly installed on one side of the base. The output end of the first motor passes through one side of the base and is fixedly connected to a bidirectional screw. A second motor is fixedly installed at the bottom of the main frame. The output end of the second motor passes through the bottom of the main frame and is fixedly connected to a gear.

[0010] In a preferred embodiment, the adjustment structure includes two first fixed seats and a connecting seat. The first fixed seats are fixedly installed on the top of the base plate, and a first connecting rod is rotatably installed between the two first fixed seats. The connecting seat is fixedly installed on the bottom of the main frame, and second connecting rods are rotatably installed on both sides of the connecting seat.

Then, a second motor is started to drive a gear to rotate, which in turn moves two racks in mesh, and then moves two bases through two connecting blocks, thereby adjusting the width of the car door placement. This allows for corresponding adjustments based on different car door models and sizes, effectively improving the applicability of the tooling.

[0014] 2. The No. 1 connecting rod is driven by the No. 3 motor to rotate, which in turn drives the two No. 2 connecting rods to perform a circular motion with the connection between the No. 1 connecting rod and the two No. 2 connecting rods as the center. This, in turn, drives the main frame to perform a circular motion with the connection between the two No. 2 fixed seats and the support seat as the center, thereby adjusting the angle of the main frame. This changes the angle of the car door, making it more convenient for workers to assemble the car door and hinges, and effectively improving the tooling's performance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figure 1-5As shown, this utility model provides a technical solution: an automotive hinge assembly angle adjustment fixture, comprising: a base plate 11 and a main frame 12. A fixing structure 2 is provided on the top of the base plate 11, and an adjustment structure 3 is provided between the base plate 11 and the main frame 12. The fixing structure 2 includes two bases 21. A bidirectional screw 22 is rotatably mounted on the inner side of the base 21. Moving blocks 23 are threadedly connected to the outer sides of the bidirectional screw 22 near both ends. A placement plate 24 is fixedly mounted on the top of each of the two moving blocks 23, and a fixing block 2 is fixedly mounted on one side of each of the two placement plates 24. 5. A pressure block 26 is slidably installed on one side of the fixed block 25. An L-shaped frame 28 is fixedly installed on the top of the base 21. A hydraulic rod 29 is fixedly installed on the top of the L-shaped frame 28. The bottom end of the hydraulic rod 29 passes through the L-shaped frame 28 and a movable frame 210 is fixedly installed thereon. Two T-shaped sliding plates 211 are provided on the inner side of the movable frame 210. A connecting rod 212 is fixedly installed at the bottom of each of the two T-shaped sliding plates 211. The bottom ends of the two connecting rods 212 pass through the tops of the two fixed blocks 25 and are fixedly connected to the two pressure blocks 26 respectively. A first sliding groove is opened on the top of the base 21. Each movable block 23 is disposed inside the first sliding groove and slides in contact with the base 21. A T-shaped sliding groove is provided at the bottom of the movable frame 210. Two T-shaped sliding plates 211 are disposed inside the T-shaped sliding groove and slide in contact with the movable frame 210. Two guide rods 213 are fixedly installed between the L-shaped frame 28 and the base 21. Both guide rods 213 pass through the movable frame 210 and slide in contact with the movable frame 210. A gear 214 is rotatably installed on the inner side of the main frame 12. Two racks 215 are meshed on the outer side of the gear 214. The tops of the two racks 215 are fixedly installed with... There is a connecting block 216. The top of the main frame 12 has two rectangular sliding grooves. The two connecting blocks 216 are respectively set inside the two rectangular sliding grooves and slide in contact with the main frame 12. The two connecting blocks 216 are respectively fixedly connected to the two bases 21. A first motor 27 is fixedly installed on one side of the base 21. The output end of the first motor 27 passes through one side of the base 21 and is fixedly connected to the bidirectional screw 22. A second motor 217 is fixedly installed at the bottom of the main frame 12. The output end of the second motor 217 passes through the bottom of the main frame 12 and is fixedly connected to the gear 214.

[0025] In this embodiment, both movable blocks 23 are disposed inside the first sliding groove of the base 21 and slide in contact with it. When the bidirectional screw 22 rotates, it can limit the movement of the two movable blocks 23, preventing them from rotating. This ensures that the two movable blocks 23 can drive their top structures to move in opposite directions. Through the cooperation of the T-shaped sliding groove at the bottom of the movable frame 210 and the two T-shaped sliding plates 211, the two T-shaped sliding plates 211 can slide correspondingly inside the T-shaped sliding groove when the two movable blocks 23 drive their top structures to move, thereby ensuring that the movement is smooth. When the moving frame 210 moves up and down, it can exert corresponding up and down forces on the two T-shaped sliding plates 211. The two guide rods 213 that pass through the moving frame 210 can effectively guide the up and down movement of the moving frame 210, making the movement of the moving frame 210 more stable. The two rectangular sliding grooves opened in the main frame 12 can effectively limit the connecting block 216, thereby limiting the rack 215 at the bottom of the two connecting blocks 216, thus ensuring that the two racks 215 will not move out of place and cause the gear 214 to disengage. Example

[0026] like Figure 1 , 2 As shown in Figure 6, the adjustment structure 3 includes two first fixed seats 31 and a connecting seat 34. The first fixed seats 31 are fixedly installed on the top of the base plate 11. A first connecting rod 32 is rotatably installed between the two first fixed seats 31. The connecting seat 34 is fixedly installed on the bottom of the main frame 12. Second connecting rods 33 are rotatably installed on both sides of the connecting seat 34. The first connecting rod 32 is rotatably connected to the two second connecting rods 33. A support seat 36 is fixedly installed on the top of the base plate 11. Two second fixed seats 35 are fixedly installed on the bottom of the main frame 12. The support seat 36 is located between the two second fixed seats 35 and is rotatably connected to the two second fixed seats 35. A third motor 37 is fixedly installed on one side of one of the first fixed seats 31. The output end of the third motor 37 passes through one of the first fixed seats 31 and is fixedly connected to the first connecting rod 32.

[0027] In this embodiment, the rotational connection between the support base 36 and the two second fixed bases 35 allows the main force point of the main frame 12 to be located at the connection between the support base 36 and the two second fixed bases 35. When the main frame 12 rotates, it can rotate around the connection between the two second fixed bases 35 and the support base 36. Through the cooperation of the first connecting rod 32 and the second connecting rod 33, the first connecting rod 32 can be rotated by the third motor 37. The second connecting rod 33, which is rotatably connected to the first connecting rod 32, will rotate accordingly, thereby driving the connecting base 34 and the main frame 12 on one side of the two second connecting rods 33 to rotate. The first connecting rod 32 and the two second connecting rods 33 are in surface contact, resulting in low pressure, the ability to withstand large loads, and impact resistance, making the structure more stable in use.

[0028] Working principle:

[0029] like Figure 1-6 As shown, in use, the car door is placed on top of the four placement plates 24. Then, the two hydraulic rods 29 are activated to move the two moving frames 210 downwards. The two T-shaped sliding plates 211 then move the two connecting rods 212 downwards, causing the pressure blocks 26 at the bottom of the connecting rods 212 to move accordingly. This clamps and secures the car door placed on top of the placement plates 24, allowing for the assembly of the car hinges. When installing car door hinges of different sizes, the first motor 27 is activated. The specific model of the first motor 27 is not described here; the model should be determined based on the compatible equipment. The first motor 27 will... The double-acting screw 22 rotates, causing two moving blocks 23 to move in opposite directions, which in turn moves the top mounting plate 24, thereby adjusting the length of the car door. Then, the second motor 217 is started. The specific model of the second motor 217 is not described here, but depends on the compatible equipment. The second motor 217 drives the gear 214 to rotate, which in turn drives the two racks 215 to mesh and move. Then, through the two connecting blocks 216, the two bases 21 move, thereby adjusting the width of the car door. This allows for corresponding adjustments based on different car door models and sizes, effectively improving the applicability of the tooling.

[0030] During hinge assembly, motor 37 (the specific model of motor 37 is not described here, but refers to the compatible equipment) is started. Motor 37 drives the first connecting rod 32 to rotate, which in turn drives the two second connecting rods 33 to perform a circular motion centered on the connection between the first connecting rod 32 and the two second connecting rods 33. This, in turn, drives the main frame 12 to perform a circular motion centered on the connection between the two second fixed seats 35 and the support seat 36 via the connecting seat 34. This adjusts the angle of the main frame 12, thereby changing the angle of the car door. This makes it easier for workers to assemble the car door with the hinge and effectively improves the tooling's performance.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
