Description

Technical Field

[0001] The utility model belongs to the technical field of truss robots, and in particular relates to a truss robot for a numerically controlled machine tool. Background Art

[0002] A gantry robot is also called a gantry robot. In industrial applications, it is a multi-purpose manipulator that can realize automatic control, reprogrammable, and has freedom of movement. It can carry objects and operate tools to complete various tasks. It is widely used in production workshops to grab and transfer objects.

[0003] At present, in order to facilitate the loading and unloading of some materials with heavy weight in CNC machine tool processing, truss robots are usually built on both sides of the CNC machine tool. Among them, the document CN208375290U discloses a heavy-load truss robot, which mainly solves the problem that the existing truss robot has a large load limit and is difficult to lift and carry heavy parts. However, it was found in the long-term use process that the specific structure of the truss robot, when facing the shaking of objects during the transportation process, because the rack and the guide rail are located on the same side wall, the gear and rack of the drive motor are easily unstable when the object shakes, thereby producing abnormal noise during operation. In order to optimize this solution, practitioners have designed a truss robot for CNC machine tools. Utility Model Content

[0004] The purpose of the utility model is to provide a truss robot for CNC machine tools in order to solve the problem that when the existing truss robot is lifting a heavy object and the meshing between the rack and the gear is unstable, thereby generating abnormal noise during operation.

[0006] Furthermore, a mounting base plate is provided at the bottom of each column, and threaded holes are provided at four corners of the mounting base plate.

[0007] Furthermore, the driving body is sleeved on the outside of the running beam.

[0008] Furthermore, a blowing duct is arranged on the upper side wall of the driving body, the blowing duct is arranged along the guide groove, and the angle between the blowing duct and the horizontal plane is 45°.

[0009] Furthermore, anti-collision components are provided at both ends of the rack located on the side wall of the running beam;

[0010] The anti-collision component comprises an anti-collision bottom plate, an extension plate is arranged on the surface of the anti-collision bottom plate, and a rubber column is arranged at the end of the extension plate.

[0011] Furthermore, a nitrogen spring is provided on the inner wall of the driving body, and there is a gap between the end of the nitrogen spring and the running beam.

[0012] Beneficial effects: The utility model has reasonable design, simple and stable structure, strong practicality, and has the following beneficial effects:

[0013] 1. The auxiliary wheels and sliders assist the driving body from top to bottom, which can reduce the shaking feeling of the driving body during the subsequent material shaking process, and also ensure the balance of the force points during the operation process, without causing the stress to be biased to one side;

[0014] 2. The lifting hook is located directly below the driving body, which can try to keep the center of gravity of the material from deviating to the side after lifting, thereby avoiding greater force on one side of the driving body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1:

[0022] Combination Figure 1 to Figure 2 A truss robot for a CNC machine tool shown in the figure comprises two sets of columns 1 arranged opposite to each other, a mounting base plate 12 is arranged at the bottom of each column 1, threaded holes are opened at the four corners of the mounting base plate 12, and the columns 1 are conveniently fixed to the ground through the threaded holes to ensure the installation in the subsequent use process, a running beam 2 is arranged between the two sets of columns 1, a driving body 3 is arranged on the running beam 2, and the driving body 3 is sleeved on the outer side of the running beam 2 to ensure that even if the driving body 3 is at risk of derailment, it will not fall directly to the ground, but will be hung on the running beam 2, a lifting hook 4 is arranged at the bottom of the driving body 3, and the lifting hook 4 is located directly below the driving body 3 to ensure that the center of gravity will not shift to one side of the driving body 3 when the object is subsequently lifted, A guide groove 5 is provided on the upper surface of the running beam 2, and an auxiliary wheel 6 matched with the guide groove 5 is arranged above the cavity of the driving body 3. This arrangement can avoid shaking during the subsequent operation of the driving body 3 and improve the meshing degree of the rack 9 and the gear 11. A guide rail 7 is provided at the bottom of the running beam 2, and a slider 8 matched with the guide rail 7 is provided below the cavity of the driving body 3. This part forms an upper and lower cooperation with the auxiliary wheel 6 to ensure the stability of the overall structure of subsequent operation. Among them, a rack 9 is provided on the side wall of the running beam 2, and a driving motor 10 is provided on the side wall of the driving body 3. The rotating shaft of the driving motor 10 passes through the driving body 3 and is provided with a gear 11. The rack 9 is meshed with the gear 11, thereby ensuring the most basic driving effect.

[0023] In this embodiment, a blowing duct 13 is arranged on the upper side wall of the driving body 3. The blowing duct 13 is arranged along the guide groove 5. The angle between the blowing duct 13 and the horizontal plane is 45°. This part is mainly used to regularly clean the dust inside the guide groove 5 to avoid long-term accumulation affecting the coordination effect between the auxiliary wheel 6 and the guide groove 5.

[0024] In this embodiment, refer to Figure 3 As shown, both ends of the rack 9 located on the side wall of the running beam 2 are provided with anti-collision components 14, and the anti-collision components 14 prevent the driving body 3 from colliding with the column 1 when running to the end;

[0025] The anti-collision component 14 includes an anti-collision base plate 1401, which is the main fixed installation component. An extension plate 1402 is arranged on the surface of the anti-collision base plate 1401. The extension plate 1402 is used to prevent the anti-collision component 14 from interfering with other components. A rubber column 1403 is arranged at the end of the extension plate 1402. The material of the rubber column 1403 itself has a certain elastic effect, which can reduce a certain impact. In addition, its service life is relatively long.

[0026] In this embodiment, a nitrogen spring 15 is provided on the inner wall of the driving body 3. There is a gap between the end of the nitrogen spring 15 and the running beam 2. The nitrogen spring 15 is a preset component. Its main function is to passively start the rollover of the driving body 3 when there is a risk of derailment of the auxiliary wheel 6, and then act on the side wall of the running beam 2 to avoid further rollover of the driving body 3, which may cause the risk of the slider 8 detaching from the guide rail 7.
