[0032] The following disclosure provides many different embodiments or examples for implementing the different aspects of the present application.

[0033] As Figures 1 to 4The utility model discloses a gantry machining device, including first column 1, second column 2, the beam 3 of setting on first column 1 and second column 2 and set up on the machining device 4 of beam 3, its characterized in that, the front end of beam 3 has the gap 5, and the gap 5 forms bottom mounting surface 31 and front mounting surface 32, is provided with bottom guide rail 311 on bottom mounting surface 31, is provided with front guide rail 321 on front mounting surface 32, machining device 4 is slidably arranged on beam 3 through bottom guide rail 311 and front guide rail 321, and at least part of machining device 4 is supported above bottom guide rail 311.

[0034] Wherein, first column 1, second column 2 and the beam 3 of setting on first column 1 and second column 2 are the main basic framework of gantry machining device, and first column 1 and second column 2 are the stable support of beam 3, and beam 3 provides installation and movement foundation as the bearing platform for machining device 4, and machining device 4 is the component of gantry machining device directly used for carrying out various machining operations on workpiece.

[0035] Meanwhile, bottom guide rail 311 is arranged on bottom mounting surface 31, and front guide rail 321 is arranged on front mounting surface 32, machining device 4 is slidably arranged on beam 3 through bottom guide rail 311 and front guide rail 321, and at least part of machining device 4 is supported above bottom guide rail 311.When machining device 4 is slidably installed on beam 3, its gravity can be decomposed into two components perpendicular to bottom mounting surface 31 and parallel to front mounting surface 32.Bottom guide rail 311 on bottom mounting surface 31 provides a larger support area, and the contact pressure between bottom guide rail 311 and machining device 4 is relatively uniform, so that bottom guide rail 311 bears most of the weight of machining device 4.The unit pressure borne by bottom guide rail 311 is within a reasonable range, so that the main weight part of machining device 4 can be stably supported.The front guide rail 311 of front mounting surface 32 bears a small part of the weight, can cope with the additional force component generated by the specific angle movement of machining device 4 when machining device 4 moves up and down in the vertical direction or carries out complex processes such as inclined cutting, and plays the role of auxiliary balance and positioning, limits the movement of machining device 4 in the unintended direction, so that the movement of machining device 4 on beam 3 is more accurate and orderly, and the precision requirement of machining is guaranteed.Bottom guide rail 311 and front guide rail cooperate with each other, so that the overall stress of beam 3 is more balanced, the carrying capacity of beam 3 to machining device 4 and the stability of the movement of machining device 4 on beam 3 are enhanced, and the situation that beam is deformed or the precision of machining device 4 is reduced due to excessive local stress is effectively reduced,

[0036] In some embodiments, as Figure 1 And Figure 2As shown, the bottom mounting surface 31 and the front mounting surface 32 are arranged in an L shape, the front guide rail 321 includes a first front guide rail 3211 and a second front guide rail 3212, and the first front guide rail 3211 and the second front guide rail 3212 are located in the same vertical plane. The L-shaped arrangement of the bottom mounting surface 31 and the front mounting surface 32 can make full use of the space at the front end of the beam, so that the installation and movement of the machining device 4 on the beam 3 are more stable. When the machining device 4 is in a working state, whether it is subjected to a cutting force from the horizontal direction, a feed resistance, or a force in the vertical direction due to its own gravity or machining action, the two mounting surfaces of the L shape can work together to effectively support and transmit the force. For example, when milling is performed, the horizontal cutting force generated by the machining device 4 on the workpiece can be transmitted to the beam 3 through the bottom mounting surface 31, and when the height of the machining device needs to be adjusted or vertical machining action is performed, the front mounting surface 32 can better bear the corresponding vertical force, avoiding instability such as tilting and shaking of the machining device, and improving the stability and precision of machining.

[0037] In actual machining process, the machining device 4 often needs to be accurately adjusted in the vertical direction, such as when drilling, the up-down position of the machining device needs to be accurately controlled according to the thickness of the workpiece and the machining requirements. The first front guide rail 3211 and the second front guide rail 3212 in the same vertical plane provide accurate and stable vertical movement guidance for the machining device 4, so that the machining device 4 can move along the predetermined straight line track during up-down movement, effectively reducing the vertical movement deviation caused by unreasonable guide rail layout, improving the vertical precision of machining, and the machined workpiece can better meet the machining requirements in terms of verticality of holes and parallelism between planes. At the same time, the first front guide rail 3211 and the second front guide rail 3212 work together, compared with a single front guide rail, they can share more force from the vertical direction, and enhance the stability and carrying capacity of the machining device 4 during vertical movement, further improving the reliability of the entire gantry machining device when performing various complex machining tasks.

[0038] In some embodiments, as Figure 4As shown, the top of the cross beam 3 is provided with an upper mounting surface 33, which is parallel to the bottom mounting surface 31, and the upper mounting surface 33 is provided with an upper guide rail 331, and the machining device 4 is also connected with the cross beam 3 through the upper guide rail 331, and at least part of the machining device 4 is supported above the upper guide rail 331. By further increasing the upper mounting surface 33 and the upper guide rail 331, a new support dimension is added to the machining device 4, and when the machining device 4 is working, especially when facing larger cutting force or machining some large and heavy workpieces, the upper guide rail 331 can further share the force with the bottom guide rail 311 and the front guide rail 321, thereby avoiding deformation and accelerated wear of the guide rail due to excessive force on a certain guide rail, thereby prolonging the service life of the guide rail and the entire gantry machining device.

[0039] At the same time, in the process of sliding of the machining device 4 along the cross beam 3, the upper guide rail 331 also plays a further guiding role, and since it is parallel to the bottom guide rail 311, it can better constrain the movement of the machining device 4 in the vertical direction, so that the machining device 4 always maintains good straightness and parallelism when moving, and the movement trajectory of the machining device 4 is more accurate, thereby further improving the machining precision of the entire gantry machining device.

[0040] In some embodiments, as shown in Figure 1 and 2 The front mounting surface 32 is provided with a power device 6, which includes a motor 61 fixed on the front mounting surface 32, a lead screw 62 drivingly connected with the motor 61, a drive nut 63 arranged on the lead screw 62, and a lead screw mounting seat 64 arranged at the end of the lead screw 62, the lead screw mounting seat 64 is fixed on the front mounting surface 32, and the machining device 4 is connected with the drive nut 63. The rotating power generated by the motor 61 is transmitted to the lead screw 62, and the lead screw 62 makes the drive nut 63 move linearly through screw transmission, and the machining device 4 is connected with the drive nut 63, and finally drives the machining device 4 to realize linear feeding motion along the cross beam 3, and the lead screw mounting seat 64 reliably fixes the lead screw 62 on the front mounting surface 32, which guarantees the stability and accuracy of the entire transmission process. The components of the power device 6 work cooperatively to provide a motion control basis for the machining operation of the gantry machining device.

[0041] In some embodiments, as shown in Figure 1 and Figure 3As shown, a first groove 322 and a second groove 323 are formed on the front mounting surface 32. The first groove 322 and the second groove 323 are disposed between the plurality of front guide rails 321 or / and between the front guide rail 321 and the bottom guide rail 311. There are at least two power units 6, which are disposed in the first groove 322 and the second groove 323, respectively. The first groove 322 and the second groove 323 provide precise positioning and suitable installation space for the power unit 6, so that the power unit 6 does not encroach on the normal working space of the guide rails and affect the smooth sliding of the processing device 4 on the guide rails. Furthermore, the gaps between these components are cleverly utilized, resulting in a compact and efficient layout of the entire front mounting surface 32.

[0042] When the power unit 6 is installed in the first groove 322 and the second groove 323, its relative position to the front guide rail 321 and the bottom guide rail 311 is just right, facilitating the subsequent connection between the power unit 6 and the processing device 4, making power transmission smoother and ensuring that the processing device 4 can accurately move along the guide rails based on the power provided by the power unit 6. At the same time, the first groove 322 and the second groove 323 can be equipped with at least two power units 6, each of which can independently provide power to a processing device 4. This allows the gantry processing device to better adapt to the requirements of different workpieces, different processing technologies, and different production rhythms, fully leveraging the synergistic advantages of multiple power units 6 and processing devices 4, and significantly improving the processing efficiency of the gantry processing device.

[0043] In some embodiments, as Figure 1 and 2 As shown, the bottom guide rail 311 and the front guide rail 321 are each provided with a plurality of sliders 34, and the processing device 4 is fixedly connected to the sliders 34. The processing device 4 slides in contact with the sliders 34 of the bottom guide rail 311 and the front guide rail 321, effectively reducing friction between the processing device 4 and the bottom guide rail 311 and the front guide rail 321, thereby increasing the service life of the bottom guide rail 311 and the front guide rail 321. At the same time, the plurality of sliders 34 work together to constrain the processing device 4 to move according to the straightness and parallelism requirements set by the bottom guide rail 311 and the front guide rail 321, further enhancing the stability of the processing device 4 moving on the crossbeam 3.

[0044] At the same time, the processing device 4 will be subjected to various external forces such as its own gravity and cutting force during operation. These external forces are transmitted to the slider 34 through the processing device 4, and then transmitted to the lifting bottom guide rail 311 and the front guide rail 321 and even the crossbeam 3 by the slider 34. The slider 34 can optimize the transmission and distribution of forces, and evenly disperse these forces to the lifting bottom guide rail 311 and the front guide rail 321, so as to avoid deformation or damage to the lifting bottom guide rail 311 and the front guide rail 321 due to excessive local forces.

[0045] In some embodiments, as shown in Figure 1 and Figure 3 The machining device 4 includes a spindle box 41 and a spindle 42 arranged in the spindle box 41, and the spindle box 41 is slidably arranged on the beam 3 through the bottom guide rail 311 and the front guide rail 321. At the same time, the center of gravity of the spindle box 41 is located above the bottom guide rail 311 or on the side of the vertical support plane of the bottom guide rail 311 close to the front guide rail 321.

[0046] When the center of gravity of the spindle box 41 is located above the bottom guide rail 311, most of the weight of the machining device 4 can be directly transmitted to the beam 3 through the bottom guide rail 311, the carrying capacity of the bottom guide rail 311 can be fully utilized, the machining device 4 arranged on the beam 3 is more stable, and the instability phenomenon such as inclination and shaking caused by the deviation of the center of gravity is avoided, which helps to maintain the balance of the overall structure of the gantry machining device and ensures the machining precision.

[0047] In addition, the center of gravity of the spindle box 41 can also be located on the side of the vertical support plane of the bottom guide rail 311 close to the front guide rail 321. When the machining device 4 performs some complex motion that needs to consider both horizontal and vertical directions, such as inclined milling, drilling, or during rapid movement, because the center of gravity is close to the front guide rail 321, the front guide rail 321 can better share a part of the additional force component caused by the deviation of the center of gravity or motion, and cooperate with the bottom guide rail 311 to maintain the balance and stability of the machining device 4, which helps to improve the motion stability of the machining device 4 under various complex working conditions, reduce the machining error caused by uneven stress and unstable center of gravity, and improve the machining quality and reliability of the entire gantry machining device, so that it can better meet the diversified machining task requirements.

[0048] In some embodiments, as shown in Figure 1 The first column 1, the second column 2 and the beam 3 are integrally formed, the bottom mounting surface 31 and the front mounting surface 32 are transitioned through a circular arc, and the bottom mounting surface 31 and the front mounting surface 32 are perpendicular to each other. The first column 1, the second column 2 and the beam 3 adopt an integrally formed design, so that there is no problem such as loosening and wear of the connection part caused by welding and bolt connection, and the error caused by assembly is reduced, and the integrity of the overall structure is better maintained. At the same time, the integrally formed structure can more effectively transmit and disperse stress, so that the stress can be more uniformly distributed along the whole, reducing the possibility of structural deformation or damage caused by stress concentration at the connection part, and improving the overall strength and stability of the entire gantry machining device.

[0049] In addition, the transition between the bottom mounting surface 31 and the front mounting surface 32 through the circular arc shape can make the force more smooth in the transmission process, effectively disperse the stress, and effectively reduce the stress concentration at the corner, thereby improving the durability and reliability of the cross beam 3. The bottom mounting surface 31 and the front mounting surface 32 are perpendicular to each other, the bottom mounting surface 31 can mainly bear the horizontal force, such as the horizontal component of the gravity of the machining device 4, the inertial force during the horizontal feeding motion, etc., the front mounting surface 32 can mainly bear the vertical force, such as the force generated by the vertical adjustment motion of the machining device 4, the vertical cutting force during the tool cutting, etc., the two cooperate with each other to orderly and stably transmit the external force of the machining device 4 to the cross beam 3 in different motion and machining states, maintain the force balance and stability of the whole gantry machining device. At the same time, the vertical layout of the bottom mounting surface 31 and the front mounting surface 32 can provide accurate horizontal and vertical direction reference for the machining device 4, so as to reduce the motion deviation caused by the angle problem of the mounting surface during the movement and machining process.

[0050] The utility model also provides a machine tool on the other side still includes base and sets up the workstation on base, still includes any one of the gantry machining device, the gantry machining device sets up on base, and the working end of gantry machining device is towards the workstation. Since the machine tool has the foregoing gantry machining device, it also has the effects of the gantry machining device, which will not be repeated here.

[0051] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and its equivalents.
