Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an assembly tooling for an automotive energy-absorbing box. Background Technology

[0002] Energy-absorbing boxes are an important component of a vehicle's passive safety system, typically installed between the front and rear bumper beams and the vehicle's longitudinal beams. Their main function is to absorb impact energy through deformation during low-speed collisions, reducing damage to the vehicle's main structural components.

[0003] During the manufacturing process of automotive energy-absorbing boxes, multiple parts and rivets need to be installed on them. Currently, when installing parts and rivets on automotive energy-absorbing boxes, workers need to use a handheld rivet gun or electric screwdriver to install the parts. However, manual operation is prone to oversights, which can easily result in parts or rivets being missed on the automotive energy-absorbing boxes. Utility Model Content

[0004] In view of the above problems, this utility model provides an assembly tooling for an automotive energy-absorbing box.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A tooling for assembling an automotive energy-absorbing box is provided, including a tooling frame, a support rod rotatably mounted on the tooling frame, a tooling seat for mounting workpieces mounted on the support rod, a first fixing component for fixing the energy-absorbing box mounted on the support rod, a first driving component for driving the support rod to rotate on the tooling frame, an operating station for an operator to operate and install parts on one side of the tooling frame, and a detection component for detecting missing parts on the energy-absorbing box on the other side of the tooling frame.

[0007] Furthermore, the first driving component is a drive motor, and rotating shafts are fixedly installed at both ends of the support rod. The rotating shafts are rotatably connected to the tooling frame. A transmission box is fixedly installed on one side of the tooling frame, and the drive motor is connected to the rotating shafts via sprockets and chains.

[0008] Furthermore, the first fixing component includes a first driving cylinder and a transmission rod. A support seat is provided on the support rod. The first driving cylinder is fixedly mounted on the support seat. The output end of the first driving cylinder is hinged to one end of the transmission rod. A pressure block is fixedly mounted on the other end of the transmission rod. A transmission joint is hinged to the middle of the transmission rod. The other end of the transmission joint is hinged to the support seat. The pressure block is used to abut against the outer wall of the workpiece away from the support rod.

[0009] Furthermore, it also includes a second fixing component, which includes a second driving cylinder. The second driving cylinder is fixedly mounted on the support rod. A lower pressure seat is fixedly connected to the piston rod of the second driving cylinder. The lower pressure seat is used to abut against the outer wall of the workpiece away from the support rod. Positioning cylinders are fixedly mounted on both sides of the lower pressure seat. Positioning blocks are fixedly mounted on the piston rod of the positioning cylinder. The positioning cylinder is used to drive the positioning blocks to engage with the holes on both sides of the workpiece.

[0010] Furthermore, the detection assembly includes a support frame fixedly mounted on a tooling base, a mounting plate fixedly mounted on the support frame, a movable plate mounted on the side of the mounting plate near the support rod, a third drive cylinder mounted on the mounting plate for driving the movable plate to move, and multiple photoelectric sensors mounted on the movable plate, each photoelectric sensor corresponding to a part mounting hole on the workpiece.

[0011] Furthermore, a parts box for holding parts is fixedly installed on one side of the tooling frame at the operating station, and an mounting bracket for attaching a rivet gun is fixedly installed on the other side of the tooling frame at the operating station.

[0012] The beneficial effects of this utility model are as follows: When the operator assembles the parts on the automotive energy-absorbing box, the energy-absorbing box is aligned and installed on the tooling base. The workpiece is fixed on the tooling base by the first fixing component. The support rod is driven to rotate by the first driving component, so that the side of the energy-absorbing box on which the part needs to be installed rotates to face the operating position. The operator then installs the part on the workpiece. After the part is installed, the first driving component is activated to drive the support rod to rotate, so that the side of the energy-absorbing box on which the part is installed rotates to face the detection component. The detection component detects the hole position of the part on the workpiece, effectively avoiding the situation of missing parts during the installation process and improving the assembly quality of the energy-absorbing box.

[0019] This application discloses an assembly fixture for an automotive energy-absorbing box, referring to... Figure 1 and Figure 2 The fixture includes a fixture frame 1, on which a support rod 2 is rotatably mounted. The axis of the support rod 2 is horizontal, and both ends of the support rod 2 are fixedly connected to rotating shafts. The support rod 2 is rotatably connected to the fixture frame 1 via the rotating shafts. The fixture frame 1 is equipped with a first driving component 4 for driving the support rod 2 to rotate. The axis of the support rod 2 is parallel to the axis of the rotating shaft. The support rod 2 is equipped with a fixture seat 21 for mounting workpieces, which can be fitted with the workpiece. The support rod 2 is equipped with a first fixing component for fixing the energy-absorbing box. One side of the fixture frame 1 is equipped with an operating station for operators to operate and install parts, and the other side of the fixture frame 1 is equipped with a detection component 5 for detecting missing parts on the energy-absorbing box.

[0020] In this embodiment, the first driving component 4 can be a drive motor. A transmission box is fixedly mounted on the tooling frame 1, and the drive motor is installed inside the transmission box. The output shaft of the drive motor is connected to the rotating shaft via a sprocket and a chain. In other embodiments, the drive motor can also drive the rotating shaft to rotate via gears. By driving the support rod 2 to rotate, the side of the part to be installed on the tool rotates to face the operating station or detection component 5.

[0021] Reference Figure 3 and Figure 4Specifically, the first fixing component can consist of a first driving cylinder 31 and a transmission rod 32. A support base 22 is fixedly installed on the support rod 2, and a transmission joint 33 is hinged to the transmission rod 32. The end of the transmission joint 33 away from the transmission rod 32 is hinged to the support base 22. The first driving cylinder 31 is fixedly installed on the support base 22 by screws. The piston rod of the first driving cylinder 31 is hinged to one end of the transmission rod 32, and a pressure block 34 is fixedly installed on the other end of the transmission rod 32. The pressure block 34 is located on the side of the transmission rod 32 closer to the support rod 2. The pressure block 34 and the first driving cylinder 31 are respectively connected to both sides of the transmission joint 33 on the transmission rod 32. As the piston rod of the first driving cylinder 31 extends and retracts, it can push the transmission rod 32 to rotate, so that the pressure block 34 can press against the outer wall of the workpiece.

[0022] Furthermore, a second fixing assembly is included, which may consist of a second drive cylinder 61 and a lower pressure seat 62. The second drive cylinder 61 is fixedly mounted on the support rod 2 by screws, and the piston rod of the second drive cylinder 61 is fixedly connected to the lower pressure seat 62. The axis of the piston rod of the second drive cylinder 61 is parallel to the axis of the piston rod of the first drive cylinder 31. The lower pressure seat 62 is fixedly connected to the piston rod of the second drive cylinder 61. By driving the lower pressure seat 62 downward by the second drive cylinder 61, the workpiece can be stably pressed onto the tooling base 21 in conjunction with the first fixing assembly.

[0023] Positioning cylinders 63 are fixedly connected to both sides of the lower pressure seat 62. The positioning cylinders 63 are located opposite to the two sides of the workpiece. Positioning blocks 64 are fixedly installed on the piston rod of the positioning cylinder 63. As the piston rod of the positioning cylinder 63 extends, the two positioning blocks 64 are respectively inserted and engaged with the holes on both sides of the workpiece. By using the two positioning cylinders 63 and the positioning blocks 64, the workpiece on the tooling seat 21 can be further positioned and fixed.

[0024] In this embodiment, the detection component 5 includes a support frame 51 vertically fixedly installed on the side edge of the tooling base 21.

A third drive cylinder 54 is provided on the mounting plate 52 to drive the movable plate 53 to move. Multiple photoelectric sensors 55 are provided on the movable plate 53, each photoelectric sensor corresponding to a part mounting hole on the workpiece. During the rotation of the support rod 2, the third cylinder drives the movable plate 53 to move closer to the mounting plate 52, making room for the rotation of the support rod 2 and the tooling base 21. When all parts on the workpiece are installed and a check for missing parts is needed, the side of the workpiece with the parts is rotated towards the detection component 5. The third cylinder drives the movable plate 53 to move closer to the workpiece, bringing each photoelectric sensor 55 on the movable plate 53 closer to the workpiece. The photoelectric sensors 55 detect whether any parts are installed in the part mounting holes on the workpiece. This allows for simultaneous detection of multiple part mounting holes on one side of the workpiece, effectively reducing the possibility of missing parts.

[0025] In this embodiment, a parts box 7 is fixedly mounted on one side of the tooling frame 1 at the operating station, which can hold parts to be installed on the workpiece for easy access by the operator.

[0026] Furthermore, the support rod 2 is provided with multiple tooling seats 21 along its length. Different workpieces can be installed on the multiple tooling seats 21 respectively, and the workpieces can be installed from different angles. This allows operators to install parts on different surfaces of the workpieces on different tooling seats 21. At the same time, multiple operators can operate on the tooling frame 1 side, which can realize the assembly line processing of parts on the automotive energy absorption box and effectively avoid missing parts on the workpiece.
