[0002] The energy-absorbing box is an important energy-absorbing device in the automotive bumper system. It is installed between the crossbeam and the longitudinal beam of the vehicle frame. When a car is involved in a severe collision, it undergoes plastic deformation to absorb part of the impact force. The bumper beam energy-absorbing box is generally composed of the energy-absorbing box and the connecting plate. Welding these two components together requires a positioning and clamping device. The existing positioning and clamping device requires manual intervention to adjust the position of the energy-absorbing box, which is cumbersome and difficult to fix. It also makes it difficult to securely install the two components together, which makes welding difficult, resulting in poor welding effect, low overall quality, difficulty in improving production efficiency, and is not conducive to automated production.

The pressing handle is connected to the cylinder, the cylinder is connected to the union joint, one end of the hinge rod is connected to the positioning pressure head, and the other end is connected to the positioning pressure head. The cylinder drives the union joint and the hinge rod to move, and causes the positioning pressure heads in four directions to move towards the center for clamping.

[0005] In the above-mentioned integrated positioning and clamping mechanism for an anti-collision beam energy-absorbing box, an upper pressure block for the energy-absorbing box is also provided next to the positioning pressure head, and a guide head is provided on the upper pressure block for the energy-absorbing box.

[0006] In the above-mentioned anti-collision beam energy-absorbing box positioning and clamping integrated mechanism, the energy-absorbing box clamping assembly is connected to a rotary drive assembly. The rotary drive assembly includes a rotary operating handle and a rotary hinge rod connected to the rotary operating handle. The energy-absorbing box clamping assembly is connected to the rotary drive assembly. The rotary operating handle can drive the rotary drive assembly to rotate and insert the energy-absorbing box clamping assembly into the inner hole of the energy-absorbing box and contact the upper inclined surface of the energy-absorbing box.

[0007] In the above-mentioned anti-collision beam energy absorption box positioning and clamping integrated mechanism, the connecting plate placement fixture assembly includes a placement platform and a pressing component. The pressing component is connected to a pressing cylinder, and the pressing cylinder drives the pressing component to press the connecting plate on the placement platform.

[0008] In the above-mentioned anti-collision beam energy absorption box positioning and clamping integrated mechanism, a pre-compression fixing pin is provided on the placement platform.

[0009] Compared with the prior art, the advantages of this utility model are that the connecting plate for placing the fixture assembly and the energy-absorbing box clamping assembly can quickly perform positioning and clamping work. The entire positioning and clamping structure can realize the fixed installation of the energy-absorbing box and cooperate with welding. Moreover, the clamping of the energy-absorbing box ensures accurate positioning and does not affect subsequent welding work, which can meet the needs of automated production.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] In the figure, the following components are included: connecting plate placement fixture assembly 100; energy absorption box clamping assembly 200; pressing handle 300; cylinder 400; union joint 500; hinge rod 600; positioning pressure head 700; energy absorption box 800; connecting plate 900; rotating operating handle 1000; rotating hinge rod 1001; placement platform 1002; pressing component 1003; pressing cylinder 1004; pre-pressing fixing pin 1005; upper pressing block of energy absorption box 1006; and guide head 1007.

[0014] like Figure 1 and Figure 2As shown, this anti-collision beam energy-absorbing box positioning and clamping integrated mechanism includes a connecting plate placement fixture assembly 100 and an energy-absorbing box clamping assembly 200. The energy-absorbing box clamping assembly 200 includes a pressing handle 300, a cylinder 400, a union joint 500, a hinge rod 600, and positioning pressure heads 700 in four directions. The pressing handle 300 is connected to the cylinder 400, and the cylinder 400 is connected to the union joint 500. One end of the hinge rod 600 is connected to the positioning pressure head 700, and the other end is connected to the positioning pressure head 700. The cylinder 400 drives the union joint 500 and the hinge rod 600 to move, and causes the positioning pressure heads 700 in four directions to move towards the center. The clamping process is performed. The energy-absorbing box clamping assembly 200 is mainly used to clamp the energy-absorbing box 800. By manually operating the handle 300, the piston rod of the cylinder 400 drives the live joint 500 and the hinge rod 600, causing the positioning pressure heads 700 in the four directions to move towards the center until they reach the dead point position. At this time, the eight surfaces in the four directions are completely in contact with the cross rib surface of the energy-absorbing box 800, thereby achieving rapid positioning and clamping. In order to ensure the accuracy of the positioning direction, an upper pressure block 1006 for the energy-absorbing box is also provided next to the positioning pressure head 700. A guide head 1007 is provided on the upper pressure block 1006 for guiding.

[0015] A rotary drive assembly is connected to the energy-absorbing box clamping assembly 200. The rotary drive assembly includes a rotary operating handle 1000 and a rotary hinge rod 1001 connected to the rotary operating handle 1000. The energy-absorbing box clamping assembly 200 is connected to the rotary drive assembly. The rotary operating handle 1000 can drive the rotary drive assembly to rotate and insert the energy-absorbing box clamping assembly 200 into the inner hole of the energy-absorbing box and make it contact the upper inclined surface of the energy-absorbing box. Here, the energy-absorbing box clamping assembly 200 is inserted into the inner hole of the energy-absorbing box and contacts the upper inclined surface of the energy-absorbing box by rotating the rotary operating handle 1000 by 90 degrees. For initial positioning of the energy-absorbing box, the connecting plate placement fixture assembly 100 includes a placement platform 1002 and a pressing component 1003. A pressing cylinder 1004 is connected to the pressing component 1003. The pressing cylinder 1004 drives the pressing component 1003 to press the connecting plate 900 on the placement platform 1002. A pre-pressing fixing pin 1005 is provided on the placement platform 1002. Here, the pressing component 1003 and the pre-pressing fixing pin 1005 achieve a secure positioning of the connecting plate 900. The entire positioning and clamping process is accurate and does not affect subsequent welding work, which can meet the needs of automated production.
