[0020] The application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and are not a limitation on the utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0021] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and embodiments.

[0022] As Figure 1As shown, the bracket mechanism of a three-sided horizontal machine tool of this application is composed of an upper bracket 1, a buffer groove 11, a lower bracket 2, a slide groove 21, a connecting screw hole 22, a buffer hole 23, a connecting column 3, a buffer spring a4, a buffer protrusion 5, a buffer spring b6, and a fixing screw hole 7.

[0023] like Figures 1-3 As shown, both the upper bracket 1 and the lower bracket 2 are rectangular and aligned. The upper bracket 1 has a buffer groove 11 in the center at its lower part, and several fixing screw holes 7 are provided on it. These fixing screw holes 7 can be used to connect to the equipment processing the parts via bolts. Several connecting posts 3 are provided diagonally at the lower part of the upper bracket 1, and each connecting post 3 is movably fitted with a buffer spring a4. The buffer spring a4 is located between the upper bracket 1 and the lower bracket 2. When the machine tool vibrates while processing parts, this vibration is transmitted to the buffer spring a4, which can reduce the vibration of the processing equipment.

[0024] like Figures 1-3 As shown, each side of the lower support 2 is provided with a T-shaped groove 21. The groove 21 is precision machined and can cooperate with the T-shaped protrusion of the machine tool to increase stability. Connecting screw holes 22 are also provided on both sides of the lower support 2, but on the side corresponding to the groove 21. The connecting screw holes 22 are through holes with internal threads, which can be threaded to the lead screw of the machine tool. When the machine tool starts, the lower support 2 moves horizontally along with the connecting screw holes 22. Several buffer holes 23 are provided on the diagonal of the lower support 2 and can cooperate with the connecting post 3. A buffer protrusion 5 is located in the middle of the lower support 2, and there is a gap between the buffer protrusion 5 and the buffer groove 11. Several buffer springs b6 are fixedly connected between the buffer protrusion 5 and the buffer groove 11. The buffer springs b6 can further reduce the vibration of the processing equipment in the machine tool. Several spring grooves are provided on the sides of both the buffer protrusion 5 and the buffer groove 11. The two ends of the buffer springs b6 are fixedly connected in the spring grooves, and the spring grooves can prevent the buffer springs b6 from falling off.
