[0002] The top cover structure of the CNC machine tool can be opened when the CNC machine tool is in use, and materials can be added to the machine tool through the top to prevent waste chips from bursting out.

[0003] For example, a CNC machine tool top cover structure with the authorization announcement number "CN220407841U" has an upper baffle plate locked at the bottom of the connecting angle seat, a circulating structure welded under the upper baffle plate, and a connecting pipeline with claws on the circulating structure. The circulating structure flips down when the transverse push rod motor retracts, and the connecting pipeline points to the loading area of ​​the shaft head after flipping down, thereby forming a loading channel during the loading process, and the internal environment of the machine tool can be sealed during the processing to prevent debris from splashing into the external space and making it difficult to clean. However, in the use of the CNC machine tool top cover structure, the top cover is flipped down to open. At this time, the top cover is located inside the CNC machine tool, which will block some structures and reduce the internal space. When personnel add materials, they are prone to arm injuries, resulting in safety hazards in the CNC machine tool top cover structure, affecting normal use. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4In the present embodiment, a top cover structure of a CNC machine tool includes a CNC machine tool 1, and the front and rear sides of the CNC machine tool 1 are respectively connected with an opening and closing structure 2. How to operate and use the CNC machine tool 1 is already the prior art, and no further elaboration is given. The model is selected according to usage requirements. The inner wall of the opening and closing structure 2 is connected with a baffle 4, and the front and rear ends of the top of the baffle 4 are respectively fixed with a second curved plate 5, and the outer side of the top of the opening and closing structure 2 is connected with a fixed structure 3, and the inner side of the fixed structure 3 is plugged into the inner wall of the second curved plate 5.

[0021] The opening and closing structure 2 includes a cylinder 201 and a cross plate 202. The inner sides of the two cylinders 201 are respectively fixed to the front and rear sides of the CNC machine tool 1. The model of the cylinder 201 is selected according to the use requirements. The output end of the cylinder 201 is fixed to the bottom of the cross plate 202. The left and right sides of the top of the cross plate 202 are respectively fixed with a bent rod 203. The inner side of the outer wall of the bent rod 203 is slidably connected with a slot plate 204. The up and down movement of the bent rod 203 can make the slot plate 204 move left and right. The top of the slot plate 204 The straight plate 205 is fixedly connected to the inner side of the straight plate 205, and a square frame 206 is fixedly connected to the inner side of the two square frames 206. The inner sides of the two square frames 206 are fitted together, and the square frame 206 is forced to move left and right on the top of the CNC machine tool 1. The inner sides of the horizontal plate 202 and the slot plate 204 are respectively fitted with the front and rear sides of the CNC machine tool 1. The bottom of the straight plate 205 is fitted with the top of the CNC machine tool 1. The square frame 206 is located above the top opening and closing of the CNC machine tool 1. The inner wall of the square frame 206 is fixedly connected to the outer wall of the baffle 4, and the baffle 4 is a glass plate;

[0022] The working output end of the cylinder 201 in the opening and closing structure 2 drives the horizontal plate 202 to move upward, and the moving horizontal plate 202 moves the bent rod 203 upward, and the moving bent rod 203 moves outward through the inclined groove of the outer wall of the groove plate 204, and the moving groove plate 204 moves the straight plate 205 outward, so that the square frame 206 moves outward, and the two square frames 206 are opened to realize the top opening of the CNC machine tool 1, and then the material is added to the inside through the top opening of the CNC machine tool 1, and then the opening and closing structure is reversed to make the inner sides of the two square frames 206 fit together, thereby eliminating the safety hazard of the top cover structure of the CNC machine tool and ensuring normal use.

[0023] The fixed structure 3 includes a first curved plate 301 and a straight rod 302. The bottom of the first curved plate 301 is fixedly connected to the top of the straight plate 205. The inner wall of the first curved plate 301 is slidably engaged with the outer wall of the straight rod 302. The straight rod 302 slides back and forth through the inner wall of the first curved plate 301 under force. A circular plate 303 is fixedly connected to the outer side of the straight rod 302. A spring 304 is sleeved on the outer wall of the straight rod 302. The two ends of the spring 304 are respectively fixedly connected to the outer side of the first curved plate 301 and the inner side of the circular plate 303. After the circular plate 303 is forced to move outward, it rebounds due to the elastic force of the spring 304. The inner side of the outer wall of the straight rod 302 is plugged into the outer circular opening of the second curved plate 5.

[0024] Working principle:

[0025] When the structure is used, the working output end of the cylinder 201 drives the horizontal plate 202 to move upward, and the moving horizontal plate 202 moves the bent rod 203 upward. The moving bent rod 203 moves outward through the inclined groove of the outer wall of the slot plate 204, and the moving slot plate 204 moves the straight plate 205 outward, so that the square frame 206 moves outward. The two square frames 206 are opened to realize the top opening of the CNC machine tool 1, and then the material is added to the inside through the top opening of the CNC machine tool 1, and then the opening and closing are reversed. The structure allows the inner sides of the two square frames 206 to fit together. When replacing the baffle 4, the straight rod 302 is pulled outward in cooperation with the circular plate 303, so that the inner side of the outer wall of the straight rod 302 is separated from the second curved plate 5. At the same time, the circular plate 303 stretches the spring 304, and then the second curved plate 5 is pulled upward to separate the baffle 4 from the inside of the square frame 206. Then, the new baffle 4 is inserted into the square frame 206, and the circular plate 303 is released. The spring 304 provides a rebound force, so that the circular plate 303 moves inward with the straight rod 302 and is inserted into the second curved plate 5.

[0026] Embodiment 2:

[0027] See also Figure 1-4 : In this embodiment, a CNC machine tool top cover structure also includes a slide groove 6 and a bent rod 7. Multiple slide grooves 6 are respectively processed above the front and rear sides of the CNC machine tool 1. The inner wall of the slide groove 6 is slidably clamped with a bent rod 7, and the inner side of the bent rod 7 is fixedly connected to the outer side of the groove plate 204.

[0028] Working principle:

[0029] When the slot plate 204 slides left and right, the bent rod 7 will slide left and right in the sliding groove 6, and the bent rod 7 supports the slot plate 204 to ensure the movement stability of the slot plate 204.
