Description

Technical Field

[0001] This utility model relates to an installation device, and more particularly to a device that can assist workers in accurately and efficiently installing a buffer pad onto the corresponding position of the bumper assembly, belonging to the technical field of bumper buffer pad installation equipment. Background Technology

[0002] In the vehicle manufacturing industry, the installation of bumper assembly buffer pads primarily relies on manual operation. Assembly personnel visually align the buffer pads with the mounting holes on the bumper base plate before attaching and securing them. However, this existing technology has several shortcomings. First, manual operation heavily depends on worker experience, making it difficult to accurately align the buffer pads with the mounting holes on the bumper base plate. This often results in bolts or clips failing to be inserted smoothly during subsequent installation, forcing assembly personnel to make repeated adjustments and significantly reducing assembly efficiency. Second, misalignment between the buffer pads and the bumper base plate can negatively impact the bumper's collision energy absorption effect and may even cause abnormal noises or loosening. Third, any product quality defects caused by these issues will lead to serious customer dissatisfaction and complaints, negatively impacting the development of subsequent new products and the company's overall image. Therefore, a device is needed to assist workers in accurately attaching and installing buffer pads, thereby ensuring product quality. Utility Model Content

[0015] See Figure 1 , 2 and Figure 3 This utility model includes a long strip plate 1 and two padding parts; the number of padding parts is two, and they are both set on the long strip plate 1. The two ends of the long strip plate 1 are set on the ground by brackets; a bumper has two base plates, so two padding parts are provided for attaching cushioning pads to different bumper base plates respectively; the padding part includes a position adjustment mechanism, a pressing mechanism, and a padding mechanism; the position adjustment part is set on the long strip plate 1; the position adjustment part is used to adjust the position of the padding mechanism to ensure that the two padding mechanisms can simultaneously contact their corresponding bumper base plates; the pressing mechanism is set on the position adjustment mechanism, and the padding mechanism is set on the pressing mechanism; the pressing mechanism provides force to the padding mechanism, so that the padding mechanism can attach the cushioning pads to the two base plates of the bumper.

[0016] The position adjustment mechanism includes a square sleeve 2, a turntable 3, and an inclined component. A long strip 1 passes through the inner wall of the square sleeve 2, and its outer wall is in contact with the inner wall of the square sleeve 2. A threaded hole is provided on the bottom end face of the square sleeve 2, and a bolt passes through this threaded hole and presses against the bottom end face of the long strip 1. The position of the square sleeve 2 can be adjusted by sliding it, thereby adjusting the relative position between the two padding mechanisms, so that the distance between the two padding mechanisms is consistent with the distance between the two bottom plates of the bumper. Tightening the bolt at the bottom end of the square sleeve 2 fixes its position. The center axis of the bottom end face of the turntable 3 is centrally located at the center of the top surface of the outer wall of the square sleeve 2. A threaded hole is provided on the turntable 3, and a bolt passes through this threaded hole and presses against the top surface of the outer wall of the square sleeve 2. The inclined component is located on the turntable 3. Tightening the bolt on the turntable 3 fixes its relative position, preventing it from rotating.

[0017] The tilting component includes a tilting plate 4, a column 5, and an electric cylinder 6. A first hinge seat and a column 5 are provided on the top surface of the turntable 3, and their positions are symmetrical about the axis of the turntable 3. A second hinge seat and a third hinge seat are provided at both ends of the bottom surface of the tilting plate 4. The housing of the electric cylinder 6 is hinged to the first hinge seat, and the end of the piston rod of the electric cylinder 6 is hinged to the second hinge seat. The top of the column 5 is hinged to the third hinge seat. By extending and retracting the piston rod of the electric cylinder 6, the tilting plate 4 can be tilted. Combined with the rotation adjustment of the turntable 3, the tilting plate 4 can be adjusted to any desired orientation and tilt angle, making the plane of the pressure plate 10 parallel to its corresponding bumper base plate. Since the two base plate planes of the bumper are not on the same plane, the tilt angle and orientation of the two pressure plate planes 10 need to be adjusted individually to make them parallel to the corresponding bumper base plate planes.

[0018] The pressing mechanism includes a base 7, a displacement plate 8, guide rods, and an impact cylinder. The base 7 is located on the top surface of the inclined plate 4, and a hole is provided at the center of its top surface. The impact cylinder is located in the center hole of the bottom surface of the base 7. The end of the piston rod of the impact cylinder is connected to the center of the bottom surface of the displacement plate 8. The impact cylinder can provide a large forward force to the displacement plate 8 with one action, so that the buffer pad 12 on the pressure plate can be smoothly stuck to the designated position on the bumper bottom plate. Guide rods are provided at the four corners of the bottom surface of the displacement plate 8, and guide holes are provided at the four corners of the top surface of the base 7. Each guide hole of the base 7 is inserted with a corresponding guide rod. The presence of the guide rods provides guidance for the movement of the displacement plate 8, ensuring its reliable movement.

[0019] The padding mechanism includes springs 9, a central guide post, a pressure plate 10, a positioning pin 11, and a buffer pad 12. Multiple springs 9 are evenly distributed between the pressure plate 10 and the displacement plate 8. The springs act as a buffer when the displacement plate 8 impacts and moves forward, applying force to the pressure plate 10. This ensures that the force is elastic when the pressure plate drives the buffer pad 12 to press against the bumper bottom plate, preventing excessive force from deforming the buffer pad 12. A guide hole is provided at the center of the top surface of the displacement plate 8, and the central guide post on the bottom surface of the pressure plate 10 is inserted into the guide hole on the top surface of the displacement plate 8. The central guide post provides guidance for the movement of the displacement plate 8, ensuring reliable movement. Multiple threaded holes are evenly distributed on the top surface of the pressure plate 10, and an outer threaded hole is provided at the bottom of the outer wall of the positioning pin 11. The bottom ends of multiple positioning pins 11 are threaded and connected to the threaded holes in the pressure plate 10. The multiple threaded holes allow the positioning pins 11 to be flexibly adjusted to ensure that the position of each combination of positioning pins 11 corresponds to the position of the hole in the buffer pad 12, ensuring that the hole in the buffer pad 12 can be smoothly passed through by the positioning pins 11 and that the buffer pad 12 falls smoothly on the pressure plate. The number of positioning pins 11 is the same as the number of holes in the buffer pad 12, and the relative position of the positioning pins 11 is the same as the relative position of the hole in the buffer pad 12. The bottom end of the buffer pad 12 is placed on the pressure plate 10, and the adhesive side of the buffer pad 12 faces upward. Each hole in the buffer pad 12 is passed through by the corresponding positioning pin 11. The position of the hole in the buffer pad 12 is the same as the position of the through hole in the area where the buffer pad 12 is pre-attached to the bumper bottom plate.

[0020] The bumper base plate has holes for connecting to the vehicle frame. Therefore, when installing the buffer pad 12 on the base plate, the buffer pad 12 itself has holes to prevent it from blocking the holes.

[0021] Operating principle: For bumpers of the same batch, the padding part only needs to be adjusted once. After that, only the buffer pad 12 needs to be placed. The padding part will only be adjusted when the bumper is changed to a different batch, or when the spacing between the bottom plates or the position of the holes on the bottom plates changes.

[0022] The steps for adjusting the padding are as follows:

[0023] Pull the two square sleeves to make the distance between the two pressure plates 10 the same as the distance between the bottom plates at both ends of the bumper. Then, adjust the tilt position of the two pressure plates 10 by rotating the adjustment turntable 3 and adjusting the extension of the electric cylinder 6 to ensure that the planes of the two pressure plates 10 are parallel to the planes of the two bottom plates of the bumper. Then, take a bumper for simulation and control the two bottom plates of the bumper to move closer to the two pressure plates. During this process, fine-tune the spacing of the square sleeves 2 to ensure that the two bottom plates of the bumper can fall smoothly onto the two pressure plates. Then, fine-tune the position of the bumper so that the insertion holes on the two bottom plates of the bumper can match the threaded holes of the pressure plates, ensuring that each hole on the bottom plate has a corresponding threaded hole on the pressure plate. Then, pass the positioning pin 11 through the hole in the bottom plate and thread it into the threaded hole of the corresponding pressure plate 10. After all the positioning pins 11 are in place, remove the bumper and tighten the bolts on the square sleeves and turntable 3 to fix its position.

[0024] After the above preparations are completed, the above actions will not be required when installing the buffer pad 12 on the same bumper in the future.

[0025] The installation process is as follows: peel off the film on the buffer pad 12 to expose the adhesive layer, and then place it on the pressure plate 10. At this time, each positioning pin 11 passes through the corresponding hole on the buffer pad 12. After the two buffer pads 12 are placed, the worker takes a bumper and aligns the holes on the bottom plates at both ends with the corresponding positioning pins 11. Then, the two impact cylinders are activated. Under the action of the impact cylinders, the pressure plate 10 is pushed close to the bottom plate, and the buffer pad 12 on it is accurately pasted onto the bottom plate. At this time, the buffer pad 12 is successfully pasted onto the bottom plates at both ends of the bumper. Then, the bumper is removed, and the above installation action is repeated until the buffer pads 12 of all bumpers in the same batch are installed.
