[0002] In the use of bridge-type gantry automated machining platforms, heavy workpieces are generally placed on the platform, and then adjusted continuously by external equipment to achieve the workpiece position adjustment process. However, due to the large size and heavy weight of the workpieces, hoisting equipment is required to hoist and place them. If the workpiece is not placed flat during hoisting, the contact area between the workpiece and the machining platform will be small, which can easily damage the workpiece. Furthermore, during the machining process, the workpiece may also shift slightly due to vibrations generated during machining, which is not conducive to the machining process and is inconvenient to adjust. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] In the use of bridge-type gantry automated machining platforms, heavy workpieces are generally placed on the platform, and then adjusted continuously by external equipment to achieve the workpiece position adjustment process. However, due to the large size and heavy weight of the workpieces, hoisting equipment is required to hoist and place them. If the workpiece is not placed flat during hoisting, the contact area between the workpiece and the machining platform will be small, which can easily damage the workpiece. Furthermore, during the machining process, the workpiece may also shift slightly due to vibrations generated during machining, which is not conducive to the machining process and is inconvenient to adjust. Therefore, it is necessary to solve the above technical problems.

[0017] Depend on Figures 1-10This invention relates to a bridge-type gantry automated machining platform, comprising a gantry milling machine 1 with a machining platform 2. The gantry milling machine 1 includes a gantry frame 20 and a bottom platform 21 fixed to each other. The machining platform 2 is slidably mounted on the bottom platform 21, and the bottom platform 21 is provided with an axial drive assembly for driving the machining platform 2. The gantry frame 20 is provided with a planar drive assembly and a milling cutter assembly. The planar drive assembly is used to drive the milling cutter assembly to move in a plane. The machining platform 2 is provided with a horizontal rail 3 and a vertical rail 4, which are perpendicular and connected. An auxiliary unit is provided at the contact point between the horizontal rail 3 and the vertical rail 4, and a push unit for driving the auxiliary unit is provided in both the horizontal rail 3 and the vertical rail 4.

[0018] With this design, the workpiece is placed on the machining platform 2 by hoisting or other means during use. Then, the position of the workpiece on the machining platform 2 is adjusted. After the adjustment is completed, the machining platform 2 is moved by the axial drive component on the bottom platform 21, so that the machining platform 2 moves to the vicinity of the gantry frame 20. Then, the milling cutter assembly is moved by the planar drive component, so that the milling cutter assembly moves in the horizontal or vertical direction. The milling operation on the workpiece is realized by the milling cutter assembly, thus realizing the machining process of the workpiece.

[0019] It should be noted that both the axial drive assembly and the planar drive assembly use lead screw drive mechanisms. The difference is that the planar drive assembly has lead screw drive mechanisms in both the transverse and longitudinal directions to achieve position adjustment of the milling cutter assembly. The above content is all existing technology, so it will not be elaborated further.

[0020] Both of the push units work in conjunction with the auxiliary unit. Therefore, when the auxiliary unit is located at the overlap of the horizontal track 3 and the vertical track 4, one of the push units can push the auxiliary unit, causing the auxiliary unit to disengage from the other push unit. Then, under the pushing action of the previous push unit, the auxiliary unit can move linearly along the horizontal track 3 or the vertical track 4, thereby adjusting the position of the workpiece on the plane of the processing platform 2.

[0021] Specifically, the pushing unit includes a power component and a pushing block 5. The power component is fixedly installed and its output end is fixed to the pushing block 5. The auxiliary unit includes a base 6, a lifting component, a top seat 7, and an elastic support mechanism. The base 6 is slidably engaged with the horizontal track 3 and the vertical track 4, respectively. The outer wall of the base 6 is provided with at least two vertically engaged limiting grooves 8. The pushing block 5 is slidably engaged with the limiting grooves 8. The base 6 has a cavity 9. The lifting component is fixed in the cavity 9 and is used to drive the top seat 7 to move longitudinally. The elastic support mechanism is located in the top seat 7. The top seat 7 includes an upper cover 10, a middle elastic band 11, and a lower cover 12. The upper cover 10 is fixed to the lower cover 12 through the middle elastic band 11. The lower cover 12 is slidably installed in the cavity 9 and is driven by the lifting component. The elastic support mechanism is located between the upper cover 10 and the lower cover 12 for buffering.

[0022] With this design, when the workpiece is not placed on the processing platform 2, the lifting component first moves the top seat 7. More precisely, the lifting component moves the lower cover 12 upward. The lower cover 12 moves the upper cover 10 upward through the middle elastic belt 11 and the elastic support mechanism, so that the upper cover 10 extends out of the interior of the horizontal track 3 or the vertical track 4 and is higher than the processing platform 2. At this time, when the workpiece is placed on the processing platform 2, the top seat 7 can first buffer the workpiece.

[0023] To be precise, the workpiece first contacts the upper cover 10, and the upper cover 10 transmits the pressure to the elastic support mechanism. The elastic support mechanism plays the main buffering role. Since the middle elastic band 11 can deform, when the upper cover 10 and the lower cover 12 gradually approach each other, the pressure between them increases. This causes the middle elastic band 11 to deform and abut against the inner wall of the cavity 9. On the one hand, the friction between the middle elastic band 11 and the inner wall of the cavity 9 plays a role in relieving pressure. On the other hand, the combination of air pressure and the deformation of the middle elastic band 11 can enhance the buffering effect.

[0024] After the workpiece is placed and supported by multiple auxiliary units, when it needs to be adjusted, the power component drives the push block 5 to move. The push block 5 drives the base 6 to move through the limit groove 8. Thus, the push block 5 pushes the base 6 to move within the horizontal track 3, thereby adjusting the position of the workpiece located on the auxiliary unit. During this process, the push block 5 in another push unit disengages from another limit groove 8 on the base 6. In the same way, the base 6 can be moved within the vertical track 4, thereby adjusting the position of the workpiece on the processing platform 2.

[0025] After adjustment, the lifting mechanism returns the top seat 7 to its original position and no longer supports the workpiece. At this time, the upper cover 10 and lower cover 12 inside the top seat 7 are located inside the horizontal track 3 or the vertical track 4. Then, the pushing unit pushes the top seat 7 to the outer space of the workpiece. The lifting mechanism raises the top seat 7 again. After the top seat 7 is raised, it is higher than the plane of the processing platform 2. Finally, the pushing unit drives the top seat 7 to move closer to the workpiece, thereby clamping and fixing the outer wall of the workpiece through the top seat 7 to improve the stability of the workpiece during the processing.

[0026] It should be noted that reinforcing ribs can be provided in both the transverse and longitudinal directions inside the medium elastic band 11 to further improve the stress strength of the medium elastic band 11.

[0027] Specifically, the number of horizontal rails 3 and the number of vertical rails 4 can be set according to actual needs. For example, there are two horizontal rails 3 and two vertical rails 4, with the two horizontal rails 3 arranged in parallel and the two vertical rails 4 arranged in parallel.

[0028] This design allows for the installation of a corresponding number of auxiliary units at the overlap of the horizontal track 3 and the vertical track 4, based on actual needs, to meet practical requirements and improve the effective support strength for the workpiece.

[0029] Specifically, the power component includes a fixedly mounted horizontal cylinder 13, the output end of which is fixed to the push block 5. This design facilitates the movement of the push block 5 via the horizontal cylinder 13, thereby enabling the drive operation of the push block 5.

[0030] Specifically, the lifting component includes a fixedly mounted vertical cylinder 14, the output end of which is fixed to the lower cover 12. This design facilitates the movement of the lower cover 12 via the vertical cylinder 14, thereby enabling the driving operation of the top seat 7.

[0031] Furthermore, the upper cover 10 is provided with a mounting groove 15, and a platform 16 is rotatably mounted in the mounting groove 15, with the upper end face of the platform 16 protruding from the upper cover 10. With this design, when the workpiece is in an inclined state, the two auxiliary units on the same side do not move, while the two auxiliary units on the other side can move synchronously, so that the platform 16 can follow the workpiece to rotate, avoiding wear on the workpiece after rotation.

[0032] Specifically, the elastic support mechanism includes multiple elastic support components, including a guide rod 17, a support 18, and a support spring 19. The guide rod 17 is fixed to the inner bottom wall of the lower cover 12, the support 18 is fixed to the inner side wall of the upper cover 10, the guide rod 17 and the rod hole on the support 18 are slidably engaged, and the support spring 19 is wrapped around the guide rod 17 and located between the support 18 and the lower cover 12.

[0033] With this design, when the workpiece exerts pressure on the upper cover 10, the pressure is transmitted sequentially through the upper cover 10 and the support 18 to the support spring 19. The support spring 19 acts as a buffer when the workpiece is placed. When it is necessary to fix the workpiece from the side, the lower cover 12 can drive the guide rod 17 to move. The guide rod 17 drives the upper cover 10 to move through the support 18. Thus, the upper cover 10 and the lower cover 12 can clamp and fix the workpiece from the side to ensure the stability of the workpiece during processing.
