[0003] The side beams of the EMU chassis are long aluminum alloy sections, 24 to 25 meters in length, about 460 mm in height, and about 100 mm in thickness. The side beams are symmetrical on both sides. The following problems exist during the machining of the EMU chassis: (1) The side beams need to be placed horizontally during machining, and the machining surface needs to be perpendicular to the tool spindle.

The existing process model is as follows: the side beams are hoisted from the rack, then placed on the support pads, and then the bolts and pressure plates are manually installed and machined. Finally, the bolts and pressure plates are manually removed. However, the number of bolts and pressure plates that need to be manually installed and removed is large, and it is difficult to maintain consistent clamping force.

[0032] The first pressing device includes a cylinder mounting seat 3, a first rotary cylinder 2, and a first polyurethane screw pressing head 12; the second pressing device includes a second rotary cylinder 7, a guide rail 9, and a second polyurethane screw pressing head 8;

[0033] The mounting seat of the first rotary cylinder 2 is installed at a corner of one end of the base plate 1, and the first rotary cylinder 2 is installed and fixed on the cylinder mounting seat 3. The end of the piston rod of the first rotary cylinder 2 is connected to the first polyurethane screw pressure head 12, and the guide rail 9 is arranged at the other end of the base plate 1, and is diagonally opposite to the position of the cylinder mounting seat 3. The second rotary cylinder 7 is installed on the guide rail 9 and can move on the guide rail 9, and the end of the piston rod of the second rotary cylinder 7 is connected to the second polyurethane screw pressure head 8; the moving direction of the second rotary cylinder 7 is the width direction of the side beam, that is, the guide rail 9 is arranged along the width direction of the side beam, so that the clamping device can adapt to side beams of different widths; the first rotary cylinder 2 and the second rotary cylinder 7 can be rotated 90° to realize the rotation of the first polyurethane screw pressure head 12 and the second polyurethane screw pressure head 8.

[0034] Furthermore, the above-mentioned first polyurethane screw press head 12 and second polyurethane screw press head 8 have the same structure, and both press the side beam from the top of the side beam; the pressing device is suitable for fixing the side beam in the direction perpendicular to the workbench, so that the side beam will not vibrate up and down significantly during processing, keeping the processing surface level and avoiding overcutting.

[0035] Specifically, the first polyurethane screw ram 12 and the second polyurethane screw ram 8 each include a connecting block, one end of the connecting block is connected to the first rotary cylinder 2 and the second rotary cylinder 7, and the other end is provided with a screw, which is threadedly connected to the end, and a protective pad is provided at the bottom of the screw.

[0036] Furthermore, the first rotary cylinder 2 and the second rotary cylinder 7 are connected to the pressing cylinder valve, and the propulsion cylinder 6 is connected to the propulsion cylinder valve.

[0037] Furthermore, the propulsion device includes a propulsion cylinder 6, a propulsion plate 4 and a mounting plate 5; the propulsion cylinder 6 and the second rotary cylinder 7 are located at the same end of the base plate 1, the propulsion cylinder 6 is installed on the base plate 1 through the mounting plate 5, and the propulsion cylinder 6 is connected to the propulsion plate 4; the propulsion device is used to clamp and fix the side of the side beam so that the side beam will not shake or slip out of the tooling during processing, and it fixes the side beam from one side of the side beam; the other side of the side beam is positioned by the lateral positioning block of the base 10.

[0038] Furthermore, the propulsion plate 4 includes a rectangular block, and a positioning block is provided on the top of the rectangular block. The positioning block can position the side beam from the top of the side beam.

[0039] Furthermore, a guide rail may be provided at the bottom of the propulsion cylinder 6 to adjust its position.

[0040] Furthermore, the above-mentioned base 10 is installed on the base plate 1, arranged along the width direction of the profile, and located on the side where the second rotary cylinder 7 is located. A side beam pad 11 is provided on the base 10; the top surface of the side beam pad 11 is in close contact with the outer contour surface of the workpiece 13, supporting the workpiece 13 so that the upper plane of the workpiece 13 is in a horizontal state, and the bottom of the side beam pad 11 is plugged into the base 10, that is, a plurality of slots are provided on the base 10, and a plurality of plug-ins are provided at the bottom of the side beam pad 11, the plug-ins are inserted into the slots, and the shape and size of the side beam pad 11 can be adjusted according to the outer contour surface of the workpiece 13.

The lateral positioning block and the above-mentioned propulsion plate 4 are located on different sides of the side beam, and the side beam is positioned from both sides of the side beam to ensure that the side beam is on the same straight line during processing, thereby improving processing accuracy.

[0042] Furthermore, the base 10 on the tooling base plate 1 ensures that the contact surface height between the workpiece 13 and the tooling is consistent in the Y direction, which is used for the installation of the side beam pad 11.

[0043] Furthermore, the base plate 1 adopts an integral steel plate structure, which is installed on the workbench of the machining center using bolts. The base plate 1 integrates components such as the side beam propulsion device, the side beam clamping device, and the base 10 to form a long and large material processing and clamping device module.

[0044] Furthermore, the aforementioned propulsion cylinder and rotary cylinder can also be directly mounted on the processing workbench. This solution requires moving the cylinder position when switching the processing vehicle type, and the cylinder movement is very cumbersome.

[0045] The specific usage is as follows:

[0046] The fixture for processing and clamping long and large profiles consists of a propulsion cylinder valve and a clamping cylinder valve. It is simple and clear, making it easy for the operator to operate and avoid misoperation caused by complex operations. The cylinder valve operation instructions are as follows:

[0047] Advancing process: Rotating the advancing cylinder valve clockwise moves the tooling advancing device toward the workpiece 13 at a steady and moderate speed. The tooling stops advancing when the tooling advancing plate 4 is in close contact with the side beam. Rotating the advancing cylinder valve counterclockwise moves the tooling advancing device in the opposite direction of the workpiece 13, releasing the side beam.

[0048] Clamping process: Rotating the clamping cylinder valve clockwise causes the tool clamping device (first rotary cylinder 2, second rotary cylinder 7) to rotate above the side beam and move downward. After the side beam is clamped, the downward pressure stops. Rotating the clamping cylinder valve counterclockwise causes the tool clamping device pressure head to rise and rotate back to its initial position.

[0049] This fixture can be used for clamping and securing aluminum alloy underframe side beams for high-speed EMU trains. Its primary function is to secure 25-meter-long EMU underframe side beams to the machining center worktable. The fixture includes a universal base and side beam spacers, which elevate the bottom of the side beam and keep the top of the beam horizontal, ensuring that the tool is perpendicular to the beam processing surface during machining. The fixture features an automatic push mechanism and a push plate at the end to tighten the side beam. The fixture also includes an automatic clamping mechanism, where a rotary cylinder rotates the clamp 90° and presses it against the side beam processing surface. The universal base, side beam spacers, automatic push mechanism, and automatic clamping mechanism are integrated into a base plate, which is bolted to the machining center worktable. The base plate is mounted clear of the side beam processing area. If the tool interferes with the tool when switching to a different model's side beam, the entire base plate can be moved to avoid the processing area, making relocation more convenient. The contact surfaces of the universal base, side beam spacers, automatic push mechanism, and automatic clamping mechanism with the side beam are all made of aluminum.

[0050] The pusher, clamping device, and universal base of this device are integrated into the baseplate to form a module. Up to 32 modules can be used to clamp side beam profiles. The universal base of this fixture features lateral positioning blocks that automatically tighten to ensure that the side beams are machined in the same straight line, improving machining accuracy. When machining side beam profiles with varying outer contours, side beam spacers can be replaced to fit the profile, ensuring that the machined surface of the side beam is perpendicular to the tool spindle.

[0051] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
