Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, and particularly relates to a gantry frame of a five-axis machining center. Background Art

[0002] Generally, a gantry frame is arranged in a large machine tool. It is slidably arranged at the machine tool, and a numerical control machining machine for processing is generally arranged at the gantry frame, so that the machining machine can be driven to slide in multiple directions at the machine tool, so as to machine parts placed on the surface of the machine tool.

[0003] During the movement of the gantry frame, debris can be cleaned. In this process, the cleaning plate is integrally connected to the gantry frame, indicating that the cleaning of debris by the cleaning plate still generates a certain resistance to the track. At the same time, the cleaning of the cleaning plate moves with the movement of the position of the gantry frame. If the gantry frame does not move the whole journey, it will cause debris to accumulate on the machining table, affecting the flatness of the machining parts placed on the machining table. At the same time, if the debris accumulates too high, it will cause the debris to spill to both sides of the machining table, resulting in the debris falling on the slide rail and affecting the movement of the gantry frame. Content of the Utility Model

[0004] The purpose of the utility model is to provide a gantry frame of a five-axis machining center aiming at the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a gantry frame of a five-axis machining center, including a workbench. A slide rail is connected to the side of the workbench. A frame body is supported on the two slide rails. The innovation lies in that: the workbench includes a table body. A chip collection groove is opened in the middle of the table body, so that the table body forms a frame structure. A plurality of chip dropping grooves are opened on the top surface of the table body. The chip dropping grooves are communicated with the chip collection groove. A table frame protruding upward is arranged between the chip dropping grooves. The table frame is of a trapezoidal structure as a whole, and the left and right sides are inclined planes. A plurality of pairs of air outlet holes are opened in the table frame, and each pair of air outlet holes penetrates through the left and right inclined planes. A conveying air duct is longitudinally arranged in the middle of each pair of air outlet holes. The lower part of the conveying air duct is communicated by the same horizontally arranged air inlet duct. One end of the air inlet duct is closed, and the other end is open and connected to the same air pipe. The air pipe is externally connected to a gas source.

[0006] Further, baffles are arranged on the left and right sides of the top surface of the table body. The baffles are higher than the table frame, and the inside is also provided with air outlet holes, conveying air ducts and air inlet ducts, and the air inlet duct is communicated with the air pipe.

[0007] Further, the air outlet holes are located in the upper part of the table frame and are arranged obliquely downward.

[0008] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0009] By providing a bench with a trapezoidal structure, the utility model can prevent debris from staying on the bench for a long time. The debris can slide down from the inclined surface of the bench into the chip collecting groove through the chip dropping groove. Meanwhile, air is blown through the air outlet holes to blow off the attached debris, so as to completely clean the workbench, prevent debris accumulation, and avoid the unstable placement of the workpieces on the workbench caused by debris accumulation.

[0014] The following further describes the utility model with reference to the drawings.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the following further details the utility model with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0016] Refer to Figure 1-2, A gantry frame of a five-axis machining center, including a workbench 1, a slide rail 2 is connected to the side of the workbench, and a frame body 3 is supported on the two slide rails 2 together. The workbench 1 includes a table body 11, a chip collection groove 12 is opened in the middle of the table body 11, so that the table body forms a frame structure. A plurality of chip dropping grooves 13 are opened on the top surface of the table body 11, the chip dropping grooves 13 are communicated with the chip collection groove 12, and a table frame 14 protruding upward is arranged between the chip dropping grooves 13. The table frame 14 is a trapezoidal structure as a whole, and the left and right sides are inclined surfaces. A plurality of pairs of air outlet holes 15 are opened in the table frame 14, and each pair of air outlet holes 15 penetrates through the left and right inclined surfaces, and a conveying air duct 16 is longitudinally arranged in the middle of each pair of air outlet holes 15. The lower part of the conveying air duct 16 is communicated by the same horizontally arranged air inlet duct 17. One end of the air inlet duct 17 is closed, and the other end is open and connected to the same air pipe 18, and the air pipe 18 is externally connected to a gas source. Specifically, due to the inclined surfaces on the left and right sides of the trapezoidal table frame 14, the chips can be slid into the chip collection groove 12 as much as possible, and the chips are prevented from adhering to the frame body 3 as much as possible. At the same time, the width of the upper top surface of the table frame 14 is as small as possible to avoid chip adhesion. At the same time, after using for a certain period of time, the gas source is turned on, and the gas is sequentially conveyed to the air inlet duct 17 and the conveying air duct 16 through the air pipe 18, and finally discharged from the air outlet holes 15 to blow the opposite inclined surfaces respectively, and the chips on the inclined surfaces are blown off. Control the air pressure of the gas source to avoid excessive air pressure and blowing the chips too far.

[0017] In this embodiment, baffles 19 are arranged on the left and right sides of the top surface of the table body 11. The baffles 19 are higher than the table frame 14, and air outlet holes, conveying air ducts and air inlet ducts are also arranged inside, and the air inlet duct is communicated with the air pipe. The baffle 19 is used to block the chips from entering the slide rail 2 and avoid the chips from affecting the normal use of the slide rail 2 as much as possible.

[0018] In this embodiment, the air outlet holes 15 are located at the upper part of the table frame 14 and are inclined downward, so as to blow the entire inclined surface of the table frame 14 as much as possible, and blowing downward can make the chips fall into the chip collection groove 12 as much as possible. The downward inclination of the air outlet holes 15 can also prevent chips from falling into them and causing chip blockage.

[0019] The above is only used to illustrate the technical solution of the present invention and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered by the scope of the claims of the present invention.
