Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, the fixed beam gantry machining apparatus for machining a middle beam of a helicopter provided in the present embodiment includes a base 1, a table 2, a gantry structure 3, a saddle 4, and a main shaft 5. The workbench 2 is arranged on the base 1 in a sliding manner through an X-axis roller linear rail. The gantry structure 3 comprises two vertical beams 31 and a cross beam 32 which are equal in length and parallel to each other, wherein the vertical beams 31 are vertically fixed at two ends of the cross beam 32 on the workbench 2 and are respectively arranged at the top of the vertical beams 31. The saddle 4 is slidably arranged on the cross beam 32 through a Y-axis roller line rail. The main shaft 5 is vertically arranged on the saddle 4 in a sliding way. The surface of the workbench 2 is provided with a groove 21 which is convenient for clamping a workpiece to be processed, and a vacuum adsorption structure is arranged inside the groove 21. Wherein, base 1 sets up on the level ground for other structures on the supporting processingequipment, and base 1 has sufficient weight, can not shake in order to ensure other structures on the base 1 when the motion, ensures the machining precision. The workbench 2 is arranged on the base 1 in a sliding mode through the X-axis roller linear rail, and the workbench 2 can be fed on the base 1 accurately along the X-axis direction through the X-axis roller linear rail. The gantry structure 3 comprises two vertical beams 31 and a cross beam 32 which are equal in length and parallel to each other, the vertical beams 31 and the cross beam 32 are manufactured in an integral casting mode, a Y-axis roller linear rail (perpendicular to an X-axis roller linear rail) is arranged on the cross beam 32, and the gantry structure 3 is used for supporting a main shaft 5 arranged above. The main shaft 5 is fixed on a Y-axis roller linear rail of the cross beam 32 through the saddle 4, so that the main shaft 5 can displace in the Y-axis direction, and the main shaft 5 can displace in the Y-axis direction and the Z-axis direction due to the fact that the main shaft 5 can vertically slide up and down on the saddle 4, and the workbench 2 can displace in the Y-axis direction, so that the machining device can machine a three-dimensional structure. And the upper surface of the working table 2 is provided with a groove 21, the shape and specification of the groove 21 can be designed according to a specifically processed workpiece, so that the workpiece to be processed can be fixed by the groove 21. Further in order to enable the workpiece to be fixed on the surface of the workbench 2 more stably, a vacuum adsorption structure is further arranged on the workbench 2, and the workpiece is fixed on the workbench 2 through vacuum force by the vacuum adsorption structure. Because the section beam in the helicopter is of an irregular structure, effective fixation cannot be carried out only by adopting clamp clamping or only adopting a vacuum adsorption structure for adsorption (because the section beam in the helicopter is of an irregular structure, the contact area between a workpiece and a clamp is smaller when the clamp is used for clamping, so that the clamping is not firm, and the workpiece is easy to deform by adopting the clamp clamping, and when only adopting a vacuum adsorption mode, the contact area between the workpiece and the workbench 2 is small, so that the position where the vacuum adsorption structure can act on the workpiece is also small, and the workpiece is not firm to adsorb). Only when the groove 21 is adopted to improve the contact area between the fixed workpiece of the workbench 2 and the workpiece, the vacuum adsorption structure can be used for applying more positions and areas on the workpiece, so that the adsorption force is improved, the fixed beam gantry machining device for machining the middle beam of the helicopter can firmly fix the workpiece on the workbench 2, and the machining precision of the workpiece is ensured.

In order to further improve the adsorption firmness degree of the workpiece, the shape structure of the groove 21 is the same as that of the workpiece to be processed, and the workpiece to be processed is tightly attached to the groove 21 during processing. The appearance structure that sets up messenger's recess 21 is the same with the appearance of treating the processing work piece, can be so that work piece and workstation 2 between have the biggest area of contact to the area that makes the vacuum adsorption structure can act on is bigger, thereby improves the power that the vacuum adsorption structure adsorbs the work piece, and then makes the more firm fixing of work piece on workstation 2. Further, the smooth finish on the surface of the groove 21 can be improved, so that the gap between the workpiece and the groove 21 is smaller after the workpiece is contacted with the groove, the workpiece can be better matched with a vacuum adsorption structure, the amount of external air pressure leaking into the vacuum adsorption hole 22 from the gap between the workpiece and the groove 21 is reduced, a higher vacuum degree is ensured to be kept between the vacuum adsorption structure and the workpiece, the adsorption force is ensured to be at a higher level, and the workpiece is firmly adsorbed on the workbench 2.

Further, the vacuum adsorption structure includes a vacuum pump, a vacuum adsorption hole 22. The vacuum pump is used for providing vacuum degree required by vacuum adsorption. Vacuum adsorption hole 22 sets up in workstation 2 and leads to the recess 21 surface, and vacuum adsorption hole 22 is connected with the vacuum pump output through the vacuum tube. The vacuum pump gives the vacuum degree to the vacuum adsorption hole 22 in a pumping mode, and when a workpiece contacts the vacuum adsorption hole 22, the workpiece is adsorbed on the workbench 2 due to the existence of negative pressure (the external air pressure of the workpiece is large, and the air pressure of the position, close to the vacuum adsorption hole 22, of the workpiece is small).

Further, the vacuum suction holes 22 are uniformly distributed on the surface of the groove 21. The uniform lung of the vacuum adsorption hole 22 is arranged on the groove 21, so that the surface of the workpiece in the groove 21 can be subjected to uniform adsorption force, and the stability of the workpiece in the groove 21 is improved. Further, can also set up a plurality of vacuum pumps and supply the vacuum to the vacuum adsorption hole 22 of difference respectively for can not lead to whole vacuum adsorption structure to lose whole vacuum adsorption power when certain vacuum adsorption hole 22 takes place to leak gas, when preventing that the vacuum adsorption hole 22 of certain department from taking place to leak, the work piece directly takes place the displacement and breaks away from.

Further, a switch controller 6 is arranged on a vertical beam 31 of the gantry structure 3, and the switch controller 6 is electrically connected with a power supply of a vacuum generating device in the vacuum absorption structure. The switch controller 6 can control the work of the vacuum generating device in the vacuum adsorption structure, thereby being more convenient when clamping and dismounting the workpiece. And a vacuum detection device can be added on the vacuum adsorption structure, and the working condition of the vacuum adsorption structure can be judged according to the detection result.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
