[0035] Please see Figure 2 and 3 The utility model provides a machining center, including a main component 100 and a plate body 200 arranged on the main component 100, the main component 100 is used to set a motion component 101, and a connecting plate 300 is further arranged between the main component 100 and the plate body 200, the connecting plate 300 is detachably connected to the main component 100 and the plate body 200, the connecting plate 300 includes a first connecting portion 310 connected to the main component 100, and a second connecting portion 320 connected to the plate body 200, so as to facilitate the connection of the connecting plate 300 with the column 110 and the plate body 200, and a bending portion 330 is arranged between the first connecting portion 310 and the second connecting portion 320. The main component 100 includes a column 110, and the extending direction of the bending line of the bending portion 330 is a direction perpendicular to the side of the column 110 or a direction parallel to the extending direction of the column 110, that is, the extending direction of the bending line of the bending portion 330 is a horizontal or vertical direction. It can be understood that the connecting plate 300 is an intermediate plate between the main component 100 and the plate body 200. The connecting plate 300 itself has a shock-absorbing function, thereby reducing the vibration transmitted from the main component 100 to the plate body 200. At the same time, it can also reduce the vibration transmitted from the plate body 200 to the main component 100, thereby reducing the vibration of the plate body 200, ensuring the stability of the connection between the plate body 200 and the main component 100, reducing the vibration transmitted from the plate body 200 to the main component 100, and reducing the adverse effects of external vibrations on the movement accuracy of the moving component 101, thereby ensuring processing accuracy.

[0036] Please see Figure 4 and 5It can be understood that the number of the bending portions 330 can be one or more. This embodiment is described by taking the number of the bending portions 330 as more than one. Specifically, the bending portion 330 includes a first bending portion 331 formed by bending the vertical edge of the connecting plate 300 away from the column 110, and the second connecting portion 320 is arranged on the first bending portion 331.

It can be understood that the direction of the bending line of the first bending portion 331 is parallel to the extension direction of the column 110, that is, along the vertical direction, so as to reduce the vibration between the first connecting portion 310 and the second connecting portion 320 in the lateral direction. The direction of the bending line of the second bending portion 332 is parallel to the extension direction of the column 110, that is, along the vertical direction, so as to reduce the vibration between the first connecting portion 310 and the second connecting portion 320 in the lateral direction.

[0037] Please see Figure 4 and 5 The connecting plate 300 further includes a third bending portion 333 extending obliquely from the bottom toward a direction away from the connecting plate 300, the top of the third bending portion 333 is connected to the bottom of the connecting plate 300, and the side of the third bending portion 333 away from the column 110 is connected to the first bending portion 331; the horizontal distance from the third bending portion 333 to the vertical edge is the smallest at the bending line formed by the first bending portion 331 and the third bending portion 333. In this embodiment, the extending direction of the bending line of the third bending portion 333 is perpendicular to the side direction of the column 110, that is, in the horizontal direction, so as to absorb the vibration between the plate body 200 and the connecting plate 300 in the vertical direction.

[0038] Please see Figure 4 and 5The connecting plate 300 further includes a fourth bending portion 334 extending from the bottom edge of the third bending portion 333 in a direction away from the third bending portion 333, the top of the fourth bending portion 334 is connected to the third bending portion 333, and the side of the fourth bending portion 334 away from the column 110 is connected to the first bending portion 331. The angle between the fourth bending portion 334 and the third bending portion 333 is a reflex angle, for example, the reflex angle can be 120°-160°. The fourth bending portion 334 is parallel to the front side of the column 110, and the side of the fourth bending portion 334 close to the column 110 is provided with a second notch 3341, and the second notch 3341 is used to avoid the telescopic shield. By providing the second notch 3341, the connecting plate 300 can be adapted to the shape of the telescopic shield, so that the connecting plate 300 and the telescopic shield are tightly connected without generating a gap, thereby ensuring the sealing between the connecting plate 300 and the telescopic shield.

[0041] Please see Figure 2 and 3, the connecting plate 300 is located above the chassis plate 201, and the plate body 200 also includes an outer cover guard plate 202 arranged on the chassis plate 201. It can be understood that in this embodiment, the rear end of the tool magazine protection plate 400 is connected to the second bending portion 332 so that the tool magazine protection plate 400 can extend toward the front end surface of the column 110, so that the tool magazine installed on the top of the front end surface of the column 110 can be better protected, and the tool magazine can make full use of the position of the first notch 340 of the connecting plate 300, making the machining center more compact.

[0042] In some other embodiments, see Figure 2 The motion assembly 101 includes a spindle box 1011. A grating ruler 500 is provided at the front of the connecting plate 300 near the spindle box 1011.
