Technical Field
[0001] This utility model relates to a gantry casting with an external anti-collision structure, belonging to the field of gantry castings. Background Technology
[0002] The gantry frame casting is a core support structure of the machine tool. It usually adopts a portal frame design and is composed of large castings such as columns and beams. It has high strength, high rigidity and stability.
[0003] To enhance the connection and support performance of the columns and beams, existing gantry castings often have welded reinforcing ribs installed on the inner side of the connection. However, these welded reinforcing ribs are prone to cracking at the connection when impacted, which affects the connection's stability and support performance. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a gantry casting with an external anti-collision structure. This solves the problem that existing gantry castings, in order to strengthen the connection and support performance of the columns and beams, have welded reinforcing ribs installed on the inner side of the connection between the two. When the welded reinforcing ribs are impacted by an object, the connection is prone to cracking, thus affecting the connection firmness and support performance.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a gantry frame casting with an external anti-collision structure, the structure of which includes two columns spaced apart, a crossbeam, and an anti-collision reinforcement component; the crossbeam is horizontally connected to the upper ends of the two columns so that the two columns and the crossbeam form a gantry support structure; the anti-collision reinforcement component is located at the inner corner of the top of the gantry support structure to strengthen the connection between the crossbeam and the columns; The anti-collision reinforcement component includes an anti-collision outer frame and a connecting support plate. The top plate of the anti-collision outer frame is fixedly connected to the bottom surface of the crossbeam. One side of the anti-collision outer frame is fixedly connected to the inner side of the column. The other side of the anti-collision outer frame has an opening. The connecting support plate is embedded in the opening of the anti-collision outer frame. The top edge of the connecting support plate and the side away from the opening of the anti-collision outer frame both extend into a plug-in part. The two plug-in parts protrude from the outer wall of the anti-collision outer frame and are respectively embedded in the bottom surface of the crossbeam and the inner side of the column. Both the crossbeam and the outer wall of the column are provided with fixing components that are fixedly connected to the corresponding plug-in parts.
[0006] Furthermore, to improve the connection strength, the top edge and side edge of the anti-collision frame are connected to the bottom surface of the crossbeam and the inner side of the column by welding, respectively.
[0007] Furthermore, in order to reduce the transmission of vibrations generated during machine operation, a filling groove is formed between the front and rear end faces of the connecting support plate and the inner wall of the anti-collision outer frame opening, and the filling groove is filled with vibration damping material.
[0008] Furthermore, in order to disperse external forces and improve the stability of the connection, the other side of the connecting support plate is flush with the side of the opening of the anti-collision frame, and both are inclined.
[0009] Furthermore, in order to perform bolt fixing, the fixing component is specifically a bolt, and the insertion part is provided with an internal threaded hole adapted to the bolt.
[0010] Furthermore, in order to improve the connection stability between the beam and the column, two anti-collision reinforcement components are provided, and the two anti-collision reinforcement components are symmetrically arranged at the two inner corners of the top of the gantry support structure.
[0011] The beneficial effects of this utility model are as follows: An anti-collision reinforcement component is provided at the top inner corner of the gantry casting. The anti-collision outer frame in the anti-collision reinforcement component plays a role in the initial connection and fixation of the crossbeam and the column. The connecting support plate located inside the anti-collision outer frame further strengthens the connection and fixation of the crossbeam and the column through the plug-in part extending on it. Even if the anti-collision outer frame cracks at the connection due to impact, it will not affect the overall connection firmness and support performance of the anti-collision reinforcement component for the crossbeam and the column.

[0015] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution for an external anti-collision structure gantry casting: its structure includes two spaced columns 1, a crossbeam 2, and an anti-collision reinforcement component 3; the crossbeam 2 is horizontally connected to the upper ends of the two columns 1 so that the two columns 1 and the crossbeam 2 form a gantry support structure; the anti-collision reinforcement component 3 is located at the inner corner of the top of the gantry support structure to strengthen the connection between the crossbeam 2 and the columns 1; Among them, column 1 and beam 2 are integrally cast; like Figure 2 , 3 As shown, the anti-collision reinforcement component 3 includes an anti-collision outer frame 31 and a connecting support plate 32. The top plate of the anti-collision outer frame 31 is fixedly connected to the bottom surface of the crossbeam 2. One side of the anti-collision outer frame 31 is fixedly connected to the inner side of the column 1. The other side of the anti-collision outer frame 31 has an opening. The connecting support plate 32 is embedded in the opening of the anti-collision outer frame 31. The top edge of the connecting support plate 32 and the side away from the opening of the anti-collision outer frame 31 both extend with a plug-in part 33. The two plug-in parts 33 protrude from the outer wall of the anti-collision outer frame 31 and are respectively embedded in the bottom surface of the crossbeam 2 and the inner side of the column 1. The anti-collision outer frame 31 is made of aluminum alloy, which has the advantages of high hardness and strong impact resistance. The connecting support plate 32 is made of one of the following materials: carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloy, preferably cast iron, which has the advantages of strong support performance and strong shock absorption. The anti-collision outer frame 31 and the connecting support plate 32 are connected by welding. Both the crossbeam 2 and the outer wall of the column 1 are provided with fixing components that are fixedly connected to the corresponding insertion part 33.
[0016] To improve connection strength, the top edge and side edge of the anti-collision frame 31 are connected to the bottom surface of the crossbeam 2 and the inner side of the column 1 by welding.
[0017] Among them, the bottom surface of the crossbeam 2 and the inner side of the column 1 are provided with insertion grooves 11 that fit into the insertion part 33.
