For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: an energy absorption box aluminum profile sawing tooling, which includes an installation base 1 and an installation bottom plate 5. A transverse fixing portion 200 is installed on the front surface of the installation base 1, and a longitudinal supporting portion 300 is installed on the upper surface of the installation bottom plate 5. The transverse fixing portion 200 and the longitudinal supporting portion 300 respectively expand and fix the inner cavity side wall of the energy absorption box 4 and support and fix the lower surface. The transverse expansion distance of the transverse fixing portion 200 is adjustable, and the longitudinal supporting distance of the longitudinal supporting portion 300 is adjustable.

[0026] The installation base 1 and the installation bottom plate 5 are the component bearing structures of this tooling, and are respectively used for the installation of the transverse fixing portion 200 and the longitudinal supporting portion 300. Under the effect that the transverse expansion distance of the transverse fixing portion 200 is adjustable, the energy absorption box 4 with different inner cavity widths can be expanded and clamped and fixed. The longitudinal distance adjustment of the longitudinal supporting portion 300 can support the bottom of the energy absorption box 4 to support the force during downward sawing. Under the effect that the supporting and fixing lengths of both are adjustable, the fixing of energy absorption boxes of different sizes can be satisfied.

[0027] In some embodiments, to achieve the expansion ability of the transverse fixing portion 200, the transverse fixing portion 200 includes a first control component 201, an expansion component 202, and a transmission component 203. There are four groups of expansion components 202, which are respectively arranged on both sides of the first control component 201, and there are two groups on each side distributed up and down. The expansion component 202 is connected to the first control component 201 through the transmission component 203.

[0028] The first control component 201 is the power source for adjusting the expansion distance of the transverse fixing portion 200. The elongation of the first control component 201 pushes the expansion component 202 through the transmission component 203, so that the four expansion components 202 expand outwards to support and fix the inner cavity of the energy absorption box 4.

[0029] In some embodiments, the first control assembly 201 includes a first push-pull cylinder 201a. A transmission plate 201b is installed at the output end of the first push-pull cylinder 201a. Connecting grooves 201c are formed on both side walls of the transmission plate 201b.

[0030] After the first push-pull cylinder 201a extends, it pushes the transmission plate 201b to move. The transmission plate 201b drives the connecting groove 201c to move, and the connecting groove 201c drives the transmission assembly 203 to move, thereby generating a lateral thrust by means of a longitudinal thrust.

[0031] In some embodiments, the transmission assembly 203 includes a sleeve rod 203c. The sleeve rod 203c is fixedly connected to the inside of the connecting groove 201c. A sleeve 203b is sleeved on the outer wall of the sleeve rod 203c. One end of a transmission rod 203a is fixedly connected to the outer wall of the sleeve 203b.

[0032] After the transmission assembly 203 receives a lateral thrust, the sleeve rod 203c moves along with the movement of the installation groove 202c, driving the sleeve 203b to rotate and move on its outer wall. The longitudinal movement of the sleeve 203b pushes the transmission rod 203a, and the transmission rod 203a pushes the expansion assembly 202 to expand outwards.

[0033] In some embodiments, the expansion assembly 202 includes a sliding frame 202a. A runner 202b is slidably installed inside the sliding frame 202a. An installation cylinder 202c is installed at the center of the runner 202b through a bearing. The other end of the transmission rod 203a is connected to the outer wall of the installation cylinder 202c. An installation rod 202d is inserted into the inside of the installation cylinder 202c. An expansion plate 202f is installed on the installation rod 202d. The installation rods 202d between the upper and lower two groups of expansion assemblies 202 on each side are connected by a limiting plate 202e.

[0034] The sliding frame 202a plays a role in ensuring the lateral expansion trajectory of the expansion assembly 202, and the runner 202b can roll inside it to achieve smooth movement. After the transmission rod 203a pushes the installation cylinder 202c to move, it drives the runner 202b to rotate on its outer wall, and also drives the installation rod 202d and the expansion plate 202f to move. The limiting plate 202e connects and fixes the upper and lower two installation rods 202d, playing a role in preventing the installation rod 202d and the expansion plate 202f from rotating when the installation cylinder 202c rotates. The outward expansion movement of the expansion plate 202f supports and fixes the inner wall of the energy absorption box 4.

[0035] In some embodiments, the longitudinal support portion 300 includes a second control assembly 301 and a support assembly 302. The second control assembly 301 is connected to the support assembly 302.

[0036] The lifting control support assembly 302 of the second control assembly 301 adjusts the longitudinal distance to support the energy absorption box 4 at different heights.

[0037] In some embodiments, the second control assembly 301 includes a support rod 301a. One end of the support rod 301a is connected to the mounting base plate 5, and the other end of the support rod 301a is provided with a mounting frame 301b. A second push-pull cylinder 301c is installed inside the mounting frame 301b, and a push plate 301d is installed at the output end of the second push-pull cylinder 301c.

[0038] The support rod 301a supports the mounting frame 301b. The mounting frame 301b houses the second push-pull cylinder 301c. The second push-pull cylinder 301c pushes the push plate 301d to move horizontally. The shape of the push plate 301d is triangular, and the support assembly 302 is supported at different positions of its inclined surface to adjust the support distance, replacing the longitudinal support force with a horizontal support force to reduce the support pressure.

[0039] In some embodiments, the support assembly 302 includes a U-shaped tube 302b and a rolling groove 302c. The U-shaped tube 302b is installed on the upper surface of the mounting base plate 5, the rolling groove 302c is formed on the push plate 301d, both ends of the telescopic frame 302a are inserted into the two ends inside the U-shaped tube 302b, a wheel frame 302e is installed on the lower surface of the top of the telescopic frame 302a, a roller 302d is movably installed inside the wheel frame 302e, one end of a connecting rod 302f is installed on the upper surface of the top of the telescopic frame 302a, and the other end of the connecting rod 302f is installed with a support plate 302g.

[0040] The telescopic frame 302a telescopically moves up and down inside the U-shaped tube 302b, driving the connecting rod 302f and the support plate 302g to move longitudinally. The length of the connecting rod 302f offsets the lifting position of the support plate 302g from the position of the second push-pull cylinder 301c. The rolling groove 302c moves along with the push plate 301d, and the rolling groove 302c pushes the roller 302d to move. The roller 302d rolls on the wheel frame 302e to ensure that the movement process is not jammed, so as to drive the telescopic frame 302a to adjust its longitudinal position, driving the support plate 302g to stick to the bottom of the energy absorption box 4 for support.

[0041] In some embodiments, the material of the expansion plate 202f is plastic, and the soft hardness of the plastic can prevent damage to the energy absorption box 4 when the expansion plate 202f expands and supports it.

[0042] In some embodiments, the installation of the expansion plate 202f on the mounting rod 202d is detachable, and the detachable effect can facilitate the repair and replacement of the expansion plate 202f.

[0043] Working principle: Place the energy absorption box 4 on the front surface of the mounting base 1. Insert the four expansion plates 202f into the inner cavity of the energy absorption box 4. After the first push-pull cylinder 201a extends, it pushes the transmission plate 201b to move. The transmission plate 201b drives the connecting groove 201c to move. The sleeve rod 203c moves along with the movement of the mounting groove 202c, driving the sleeve 203b to rotate and move on its outer wall. The longitudinal movement of the sleeve 203b pushes the transmission rod 203a. The transmission rod 203a pushes the mounting cylinder 202c to move, driving the runner 202b to rotate on its outer wall, and also driving the mounting rod 202d and the expansion plate 202f to move. The mounting cylinder 202c drives the runner 202b to slide and rotate inside the sliding frame 202a. The outward expansion movement of the expansion plate 202f supports and fixes the inner wall of the energy absorption box 4. The second push-pull cylinder 301c pushes the push plate 301d to move horizontally. The rolling groove 302c moves along with the push plate 301d, and the rolling groove 302c pushes the roller 302d to move. The roller 302d rolls on the wheel frame 302e to ensure that the movement process is not jammed, so as to push the telescopic frame 302a to adjust its longitudinal position, driving the support plate 302g to stick to the bottom of the energy absorption box 4 for support. With the support adjustable in horizontal expansion and the support adjustable in longitudinal bottom, the energy absorption box 4 of different sizes can be fixed.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
