Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing and repair equipment technology, and in particular to an adjustable alignment tool for installing a front bumper beam. Background Technology

[0002] The front bumper beam is a critical safety component of a car body, and its installation quality directly affects the overall safety performance of the vehicle. During the final assembly or repair of a car, one of the procedures is to precisely align the front bumper beam with the pre-set mounting point at the front of the vehicle body and tighten it.

[0003] Because the front bumper beam is quite heavy and has an irregular shape, relying solely on manual labor for handling and positioning is not only extremely physically demanding and poses high safety risks, but also makes precise position control virtually impossible. Therefore, in actual production, auxiliary tooling, such as simple manual hydraulic platforms or lifting devices, is typically used to lift and support the bumper beam.

[0004] However, while these conventional auxiliary tools solve basic load-bearing and lifting problems, they still have significant technical shortcomings in the most critical precision alignment stage, especially in fine-tuning the vertical height. After lifting the crash beam to its approximate position, operators often need to make fine adjustments by manually cranking the lever or repeatedly jogging the lifting device. This operation is slow to respond and difficult to control precisely, making the alignment process time-consuming and laborious. Operators need to rely on experience and feel to try repeatedly, making it difficult to effectively guarantee installation efficiency and consistency of accuracy.

[0005] Therefore, this utility model proposes an adjustable alignment tool for installing front bumper beams to address the shortcomings of existing technologies. Utility Model Content

[0008] Preferably, the positioning adjustment mechanism further includes a second fixing block, which is fixed to the top of the base plate, and the end of the threaded rod away from the motor is rotatably connected to the second fixing block.

[0009] Preferably, the positioning adjustment mechanism further includes a sensor, which is fixed to the top plate and electrically connected to the motor.

[0010] Preferably, the tool further includes a gripper replacement mechanism disposed on the hydraulic gripper.

The locking block is slidably disposed within the hydraulic gripper, the spring abuts against the hydraulic gripper and the locking block, and the pressing plate is pressably disposed outside the hydraulic gripper. When pressed, the pressing block drives the spring to release the engagement of the clamp.

[0011] Preferably, the clamp has a guide ramp formed thereon, which is used to guide the movement of the locking block when the clamp is installed.

[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. 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.

[0020] Reference Figures 1-5The present invention provides an embodiment of an adjustable alignment tool for installing a front bumper beam, comprising a base plate 7 as the supporting base of the entire tool, a plurality of pulleys 6 rotatably mounted on the bottom of the base plate 7, and a handle 5 for pushing the tool to move fixedly connected to the base plate 7; a top plate 407 is provided above the base plate 7, and a hydraulic gripper 3 for clamping the bumper beam body 1 is fixedly connected to the top of the top plate 407; a tool rack 2 is also fixedly connected to the base plate 7, and the tool rack 2 is used to place various tools required during the installation process.

[0021] The top plate 407 is connected to the bottom plate 7 through the positioning adjustment mechanism 4 and is driven to rise and fall by the positioning adjustment mechanism 4, thereby realizing precise height adjustment and alignment of the anti-collision beam body 1 held by the hydraulic gripper 3. The positioning adjustment mechanism 4 includes a motor 402, a threaded rod 405, a threaded slider 406, a connecting rod 403 and a first fixing block 404. Specifically, the positioning adjustment mechanism 4 is described as follows: Motor 402 is fixedly mounted on the base plate 7. The output end of motor 402 is connected to one end of threaded rod 405 to drive the threaded rod 405 to rotate. The threaded rod 405 is vertically oriented. The other end of threaded rod 405, i.e., the end furthest from motor 402, is rotatably supported on the base plate 7. The inner wall of threaded slider 406 is threaded, and the threaded slider 406 is threadedly connected to the outer wall of threaded rod 405, so that when motor 402 drives threaded rod 405 to rotate, threaded slider 406... 6. It can perform reciprocating linear motion along the axial direction of the threaded rod 405. The first fixed block 404 is firmly fixed to the bottom of the top plate 407. Both ends of the connecting rod 403 are provided with rotating shafts. One end of the connecting rod 403 is rotatably connected to the threaded slider 406 through the rotating shaft, and the other end of the connecting rod 403 is rotatably connected to the first fixed block 404 through the rotating shaft. In this way, the linear motion of the threaded slider 406 can be transmitted to the first fixed block 404 through the swing of the connecting rod 403, thereby driving the entire top plate 407 to rise or fall smoothly. It also includes a second fixing block 408, which is fixedly connected to the top surface of the base plate 7. As mentioned above, one end of the threaded rod 405 is driven by the motor 402, while the other end of the threaded rod 405 away from the motor 402 is rotatably connected to the second fixing block 408 through a bearing. By fixing and supporting both ends of the threaded rod 405, the threaded rod 405 has excellent running stability when rotating at high speed, avoiding vibration or sway, thereby ensuring the smoothness of the lifting and lowering of the threaded slider 406 and the accuracy of its positioning. Meanwhile, in order to realize intelligent control and monitoring of the lifting position of the top plate 407, the positioning adjustment mechanism 4 also includes a sensor 401. The sensor 401 is fixed on the top plate 407 and electrically connected to the controller of the motor 402. The sensor 401 can detect the height or position information of the top plate 407 in real time and feed the information back to the control system. The control system accurately controls the rotation start and stop, speed and direction of the motor 402 according to the preset value or operation command, thereby realizing the automation and closed-loop control of the lifting process of the top plate 407, which greatly improves the accuracy and convenience of the positioning operation. To accommodate the installation requirements of different models or specifications of front bumper beams, the hydraulic gripper 3 in this embodiment is also equipped with a gripper replacement mechanism 8. This gripper replacement mechanism 8 includes a clamp 802 detachably mounted on the hydraulic gripper 3, and a locking block 804, a spring 803, and a pressing plate 801 for locking or releasing the clamp 802. The shape of the clamp 802 is adapted to the shape of the bumper beam body 1. The base of the clamp 802 is slidably inserted into a slot inside the hydraulic gripper 3. The locking block 804 is slidably disposed within the hydraulic gripper 3 and can extend into the slot under the action of the spring 803 to engage with a pre-set slot at the base of the clamp 802. In this way, the clamp 802 is firmly locked onto the hydraulic gripper 3; the spring 803 is disposed in the inner cavity of the hydraulic gripper 3, one end of the spring 803 abuts against the inner wall of the hydraulic gripper 3, and the other end abuts against the locking block 804, continuously applying a spring force to the locking block 804 to move it toward the clamping position of the clamp 802; the push plate 801 is movably disposed on the outside of the hydraulic gripper 3, and the inner side of the push plate 801 is linked with the locking block 804. When the push plate 801 is pressed inward, the push plate 801 drives the locking block 804 to move inward synchronously and compress the spring 803, so that the locking block 804 is disengaged from the slot of the clamp 802, thereby releasing the lock on the clamp 802; A guide ramp is also formed on the clamp 802. The guide ramp is located at the front end of the base of the clamp 802. When the clamp 802 needs to be installed, the clamp 802 is pushed into the slot of the hydraulic gripper 3. The guide ramp will first contact the popped-out block 804 and press the block 804 inward, so that the clamp 802 can slide in smoothly. When the block 804 is aligned with the slot of the clamp 802, the block 804 will automatically pop out and lock into the slot under the elastic force of the spring 803, realizing the quick self-locking installation of the clamp 802. In order to clarify the position of the anti-collision beam body 1 on the tool, the anti-collision beam body 1 in this solution is directly clamped on the clamp 802 of the gripper changing mechanism 8, and the hydraulic gripper 3 provides a stable clamping force.

[0022] Working principle: When adjusting and aligning the height, the operator starts the motor 402. The rotation of the motor 402 is transmitted to the threaded rod 405 through the drive connection, causing the threaded rod 405 to rotate around its own axis. Since the threaded slider 406 and the threaded rod 405 are connected by a thread, the rotation of the threaded rod 405 is converted into the linear lifting and lowering motion of the threaded slider 406 along the axis of the threaded rod 405. The lifting and lowering of the threaded slider 406 is transmitted to the first fixed block 404 through the rotating connecting rod 403, thereby driving the top plate 407 fixed above the first fixed block 404 to rise or fall smoothly. During this process, the sensor 401 continuously detects the position of the top plate 407 and feeds the signal back to the control system to precisely control the start and stop of the motor 402, and finally adjusts the anti-collision beam body 1 clamped on the hydraulic gripper 3 to the precise installation height. When it is necessary to replace the anti-collision beam body 1 to adapt to different models, the operator presses the push plates 801 set on both sides of the hydraulic gripper 3 inward. When the push plates 801 move inward, they will squeeze the spring 803 and drive the locking block 804 to retract inward, so that the locking block 804 disengages from the slot of the clamp 802. At this time, the old clamp 802 can be easily pulled out from the slot of the hydraulic gripper 3. When installing the new clamp 802, simply align the new clamp 802 with the slot and push it inward. The guide slope at the front end of the clamp 802 will force the locking block 804 to retract inward automatically. After the clamp 802 is fully pushed into place, the locking block 804 will automatically pop out under the reaction force of the spring 803 and re-lock into the slot of the new clamp 802, completing the quick locking.
