A tailgate support rod assembly jig

Abstract

This utility model discloses a tailgate strut assembly fixture, belonging to the field of assembly fixture technology. The tailgate strut assembly fixture includes a drive assembly and two connecting frames. The two connecting frames are fixedly connected, and the drive assembly is located above the connecting frames. Clamping components are set at both ends of the connecting frames. When the drive block is pushed upwards, the connecting shaft drives the slider upwards, causing the two support arms to respectively drive the clamping claws two and one to close and clamp the strut. At this point, it can be lifted with one hand, aligned with the installation point, and installed, thus eliminating the need for installers to touch the strut with their hands and preventing contamination of subsequently installed parts. Since the two clamping components are fixed and immovable, the strut can be fully straightened before clamping it, and then the two clamping components can clamp the inner and outer cylinders of the strut respectively, preventing the strut from retracting during installation and eliminating the need for repeated adjustments during installation.

Description

Technical Field

[0001] This utility model relates to the field of assembly fixture technology, and more specifically, to a tailgate strut assembly fixture. Background Technology

[0002] A tailgate strut assembly fixture is a tooling device specifically designed for the installation, fixing, and adjustment of automotive tailgate struts (also known as tailgate support rods or tailgate gas springs). It ensures that the struts are accurately positioned and securely installed during assembly, meeting design requirements to guarantee the normal opening and closing function and service life of the tailgate. It improves assembly accuracy, reduces human error, increases production efficiency, and shortens assembly time.

[0003] The tailgate of a car is mainly opened by the support of hydraulic struts. In traditional car assembly lines, the struts are installed manually. However, the inner cylinder of the strut is coated with a large amount of lubricating oil to allow it to extend and retract smoothly. Therefore, when you pick it up and install it by hand, your hands or gloves will inevitably come into contact with the inner cylinder, becoming covered in oil. This can easily contaminate parts when installing other components later.

[0004] Meanwhile, when installing the strut, both ends of the strut need to be installed on the tailgate and the rear pillar respectively. However, the strut has the characteristic of telescopic extension, which can easily cause the strut to retract and change its length during installation. Since the positions of the two installation points remain unchanged, after one end is installed, the strut needs to be stretched again to align with the other installation point, which causes inconvenience in installation.

[0005] Therefore, a tailgate strut assembly fixture is proposed to address the above problems. Utility Model Content

[0006] This utility model provides a tailgate strut assembly fixture, which can improve the problems existing in related technologies: In traditional automobile assembly lines, the struts are installed manually. However, the inner cylinder of the strut is coated with a large amount of lubricating oil to allow for smooth extension and retraction. Therefore, when the strut is picked up and installed by hand, the hand or gloves inevitably come into contact with the inner cylinder, resulting in oil stains. This can easily contaminate parts when installing other components later. At the same time, when installing the strut, both ends of the strut need to be installed on the tailgate and the rear pillar respectively. However, the strut has the characteristic of extension and retraction, which can easily cause the strut to retract and change length during installation. Since the positions of the two installation points remain unchanged, after one end is installed, the strut needs to be lengthened again to align with the other installation point, which causes inconvenience in installation.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] This application provides a tailgate strut assembly fixture, including a drive assembly and two connecting frames. The two connecting frames are fixedly connected, and the drive assembly is located above the connecting frames. Limiting components are provided at both ends of the drive assembly, and clamping components for clamping the strut are provided at the bottom ends of the two limiting components. The clamping components include two symmetrically arranged support arms. A first clamping claw is fixedly connected to the outer end of one support arm, and a second clamping claw is fixedly connected to the outer end of the other support arm. Clamping pouches are fixedly installed on the inner sides of both the first and second clamping claws. The ends of the two support arms are brought close to each other so that the first and second clamping claws clamp the strut through the clamping pouches.

[0009] The technical solutions described in this application embodiment have at least the following technical effects: (1) By setting clamping components at both ends of the connecting frame, when the drive block is pushed up, the connecting shaft will drive the slider to move upward. At this time, the drive shaft will drive the movable block to move, so that the two support arms will drive the second and first clamps to close and clamp the support rod. Then, it can be lifted with one hand and aligned with the installation point for installation, so that the installer does not need to touch the support rod with his hands, which can prevent the subsequent installed parts from being contaminated.

[0010] (2) Since the two clamping components are fixed and cannot be moved, they should be fully straightened before clamping the strut. Then, the two clamping components should clamp the inner and outer cylinders of the strut respectively to prevent the strut from retracting during installation. This will allow the strut to be installed in one go without repeated adjustments, thus improving the efficiency and convenience of installation.

[0011] In some embodiments, both ends of the two connecting frames are fixedly connected to a fixing frame for installing the limiting component, and a plurality of connecting plates are fixedly connected to the inner side of one of the connecting frames, and a handle is fixedly installed on the top of one of the connecting plates.

[0012] In some embodiments, a fixed rod is fixedly connected between the handle and the connecting plate, and movable grooves are provided at both ends of the handle.

[0013] In some embodiments, the drive assembly includes a drive block and two drive rods. The two drive rods are respectively fixedly installed on both sides of the drive block. The outer end of the drive block has a through hole that matches the fixed rod. The fixed rod passes through the through hole. The two drive rods extend through the two movable slots to both sides of the handle.

[0014] In some embodiments, the limiting component includes a housing and a slider. The housing is fixedly installed inside the fixing frame, and the slider is slidably connected to the inner wall of the housing. A telescopic spring is provided inside the housing, and the two ends of the telescopic spring abut against the slider and the top of the inner wall of the housing, respectively. A connecting shaft is fixedly connected to the top of the slider, and the connecting shaft extends through the inner wall of the housing to the outside, and is fixedly connected to one end of the drive rod.

[0015] In some embodiments, the clamping assembly further includes a mounting block, a movable block, and a drive shaft. The bottom end of the housing is fixedly connected to the mounting block. One end of the drive shaft passes through the bottom of the housing and is fixedly connected to the slider. The other end of the drive shaft passes through the mounting block and is fixedly connected to the movable block. One end of each of the two support arms is rotatably connected to both sides of the mounting block.

[0016] In some embodiments, both ends of the movable block are rotatably connected to connecting rods, the other end of the connecting rods is rotatably connected to the outer end of the support arm, the outer end of the first gripper is provided with a slot, and when the second gripper and the first gripper are close to each other, the outer end of the second gripper is inserted into the slot.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 A tailgate strut assembly fixture includes a drive assembly 5 and two connecting frames 1. The two connecting frames 1 are fixedly connected. The drive assembly 5 is located above the connecting frames 1. Limiting components 7 are provided at both ends of the drive assembly 5. Clamping components 6 for clamping the strut are provided at the bottom ends of the two limiting components 7. The clamping components 6 include two symmetrically arranged support arms 63. A first clamping claw 66 is fixedly connected to the outer end of one support arm 63, and a second clamping claw 67 is fixedly connected to the outer end of the other support arm 63. Clamping pouches 69 are fixedly installed on the inner sides of both the first clamping claw 66 and the second clamping claw 67. The ends of the two support arms 63 are brought close to each other so that the second clamping claw 67 and the first clamping claw 66 clamp the strut through the clamping pouches 69.

[0021] Both ends of the two connecting frames 1 are fixedly connected to a fixing frame 8 for installing the limiting component 7. Multiple connecting plates 2 are fixedly connected to the inner side of one of the connecting frames 1, and a handle 3 is fixedly installed on the top of one of the connecting plates 2.

[0022] A fixing rod 9 is fixedly connected between the handle 3 and the connecting plate 2, and movable grooves 4 are opened at both ends of the handle 3.

[0023] The device in this solution is mainly used to assist in the installation of hydraulic struts for car tailgates. Two connecting frames 1 are arranged in two layers and fixed together. They can be made of galvanized square tubing. Fixing frames 8 are fixed at both ends of the two connecting frames 1. The fixing frames 8 are mainly used to fix the limiting component 7. Two fixing frames 8 fix one limiting component 7. A clamping component 6 is installed at the bottom of the limiting component 7. The clamping component 6 is mainly used to clamp the strut, while the limiting component 7 is mainly used to cooperate with the drive component 5 to drive the clamping component 6. Three connecting plates 2 are fixed inside the upper connecting frame 1. The two ends of the handle 3 are fixed to two of the connecting plates 2. The user can lift the entire device through the handle 3. The drive component 5 is located below the handle 3 and passes through it. A fixing rod 9 is fixed between the connecting plate 2 in the middle and the handle 3. The fixing rod 9 is mainly used to raise the drive component. 5. Stability during vertical movement: Clamping components 6 are installed at both ends of the connecting frame 1. When the drive block 52 is pushed upward, the connecting shaft 73 drives the slider 74 to move upward. At this time, the drive shaft 62 drives the movable block 65 to move, so that the two support arms 63 respectively drive the second clamp 67 and the first clamp 66 to close and clamp the support rod. Then, it can be lifted with one hand and aligned with the installation point for installation. This eliminates the need for the installer to touch the support rod, preventing contamination of the parts to be installed later. At the same time, since the two clamping components 6 are fixed and cannot be moved, they can be fully straightened before clamping the support rod. Then, the two clamping components 6 clamp the inner and outer cylinders of the support rod respectively, and then the two ends of the support rod are directly aligned with the two installation points. This prevents the support rod from retracting during installation, eliminating the need for repeated adjustments and allowing for a smooth installation in one go, improving installation efficiency and convenience. Please see Figures 1-4 The drive assembly 5 includes a drive block 52 and two drive rods 51. The two drive rods 51 are fixedly installed on both sides of the drive block 52. The outer end of the drive block 52 is provided with a through hole 53 that matches the fixed rod 9. The fixed rod 9 passes through the through hole 53. The two drive rods 51 pass through the two movable slots 4 and extend to both sides of the handle 3.

[0024] The limiting component 7 includes a housing 71 and a slider 74. The housing 71 is fixedly installed inside the fixing frame 8. The slider 74 is slidably connected to the inner wall of the housing 71. A telescopic spring 72 is provided inside the housing 71. The two ends of the telescopic spring 72 abut against the slider 74 and the top of the inner wall of the housing 71, respectively. A connecting shaft 73 is fixedly connected to the top of the slider 74. The connecting shaft 73 extends through the inner wall of the housing 71 to the outside and is fixedly connected to one end of the drive rod 51.

[0025] In this scheme, the drive component 5 and the limiting component 7 work together to drive the clamping component 6. Both ends of the drive block 52 are fixed with drive rods 51, and both ends of the movable slot 4 are opened with movable slots 4. The two drive rods 51 pass through the two movable slots 4 respectively and pass through the bottom of the drive block 52. The drive block 52 and the handle 3 are coaxially set. The outer end of the drive block 52 is provided with a through hole 53, and the fixing rod 9 passes through the through hole 53 so that the drive block 52 can remain stable when moving up and down.

[0026] The housing 71 is fixed to the connecting frame 1 by the fixing bracket 8. The interior of the housing 71 is hollow. A slider 74 is slidably connected inside the housing 71. A connecting shaft 73 is fixed to the top of the slider 74. The connecting shaft 73 passes through the top of the housing 71 and extends to the outside, connecting to the drive rod 51. A telescopic spring 72 is installed inside the housing 71 and is also sleeved on the outer end of the connecting shaft 73. The two ends of the telescopic spring 72 abut against the top of the slider 74 and the housing 71, respectively. A drive shaft 62 is fixed to the bottom of the slider 74 and passes through the housing 71. Extending outwards, the force of the connecting shaft 73 can press the slider 74 downwards, so that the clamping component 6 is in an unfolded state when stationary. When the user needs to clamp the clamping component 6, he only needs to pinch the drive block 52 and the handle 3 at the same time and push the drive block 52 toward the handle 3. At this time, the drive rod 51 will move upwards with the drive block 52, so that the connecting shaft 73 drives the slider 74 and the drive shaft 62 to move upwards, while compressing the telescopic spring 72. Then, the clamping component 6 can be clamped by pulling the drive shaft 62. After releasing, it will return to its original position by the force of the telescopic spring 72.

[0027] Please see Figure 4 and Figure 5 The clamping assembly 6 also includes a mounting block 61, a movable block 65, and a drive shaft 62. The bottom end of the housing 71 is fixedly connected to the mounting block 61. One end of the drive shaft 62 passes through the bottom of the housing 71 and is fixedly connected to the slider 74. The other end of the drive shaft 62 passes through the mounting block 61 and is fixedly connected to the movable block 65. One end of each of the two support arms 63 is rotatably connected to both sides of the mounting block 61.

[0028] Both ends of the movable block 65 are rotatably connected to the connecting rod 64. The other end of the connecting rod 64 is rotatably connected to the outer end of the support arm 63. The outer end of the first gripper 66 is provided with a slot 68. When the second gripper 67 and the first gripper 66 approach each other, the outer end of the second gripper 67 is inserted into the slot 68.

[0029] The clamping assembly 6 in this design is mainly used to clamp the support rod. The housing 71 is fixed on the mounting block 61. Support arms 63 are rotatably mounted on both sides of the mounting block 61. At the same time, the drive shaft 62 also passes through the mounting block 61. A movable block 65 is fixed to the end of the drive shaft 62. Connecting rods 64 are rotatably connected to both ends of the movable block 65. The ends of the two connecting rods 64 are rotatably connected to the two support arms 63 to drive the two support arms 63. The ends of the two support arms 63 are respectively fixedly connected to the second gripper 67 and the first gripper 66. The thickness of the first gripper 66 is greater than that of the second gripper 67, and the outer end of the first gripper 66 has a slot 68, so that the protruding part of the outer end of the second gripper 67 can be inserted into the slot 68, so that the two will not block each other. When the drive shaft 62 pulls the movable block 65, since both ends of the connecting rod 64 are rotatably connected, the connecting rod 64 will change its angle and pull the two support arms 63 closer together. At this time, the second gripper 67 and the first gripper 66 will be driven to move closer together, and the outer end of the second gripper 67 will be inserted into the slot 68 to clamp the support rod.

[0030] Clamping pouches 69 are installed on the inner arc of both jaw 2 67 and jaw 1 66. The inside of the clamping pouches 69 is hollow and filled with air. Since the clamping pouches 69 are made of rubber, they have a large friction force. When jaw 2 67 and jaw 1 66 clamp the support rod, they can clamp it more stably through friction. At the same time, due to the relatively soft nature of the clamping pouches 69, it is not easy to scratch the outer surface of the support rod when clamping it with force, thus giving it better safety.

[0031] Working principle: When using this device, first, the support rod needs to be stretched out. Then, use two clamping components 6 to clamp the outer and inner cylinders of the support rod respectively. Simply pinch the drive block 52 and the handle 3 at the same time, and push the drive block 52 toward the handle 3. At this time, the drive rod 51 will move upward with the drive block 52, thereby causing the connecting shaft 73 to drive the slider 74 and the drive shaft 62 to move upward. At the same time, the telescopic spring 72 is compressed. Then, the drive shaft 62 will pull the movable block 65. Since both ends of the connecting rod 64 are rotatably connected, the connecting rod 64 will change its angle and pull the two support arms 63 closer together. At this time, the second clamp 67 and the first clamp 66 will be driven to move closer together. The outer end of the second clamp 67 is inserted into the slot 68 to clamp the support rod. Clamping pouches 69 are installed on the inner sides of both clamping claws 2 67 and clamping claw 1 66. The inside of the clamping pouches 69 is hollow and made of rubber. Therefore, when clamping claws 2 67 and clamping claw 1 66 clamp the support rod, they can clamp it more stably through friction. At the same time, due to the relatively soft nature of the clamping pouches 69, it is not easy to scratch the outer surface of the support rod when clamping it with force.
