Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

1 to 4, the present utility model will be described in detail. A CNC machine tool base involved in this embodiment includes a base side wall 1 , a top plate 2 and a bottom plate 7 . The top plate 2 is provided with a groove portion 3 along the longitudinal direction of the base, and the bottom surface of the groove portion 3 is inclined. The groove portion 3 is wedge-shaped as a whole. One end of the entire groove portion 3 is shallow and the other end is deep. This inclined arrangement enables the liquid falling on the top plate 2 to quickly flow out from the top plate 2 to the outside.

The top plate 2 is provided with a motor seat 4 and a bearing seat bracket 5 at the position of the groove portion 3 . The bottom of the motor base 4 and the bottom surface of the groove portion 3 are provided with a communication hole 13 . Two bearing seats 5 are arranged symmetrically, and there is a space between the two bearing seats 5 ; the top plate 2 is fixed with a line rail fixing portion 6 arranged in parallel. The motor seat 4 is used for fixedly installing the motor, the bearing seat bracket 5 is used for installing a bearing seat, and a rod pair is arranged between the motor and the bearing seat. A Y-axis rail is fixedly installed on the line rail fixing part 6, and a saddle is provided on the Y-axis rail.

In this embodiment, the bottom plate 7 is hollow, and the top plate 2 and the bottom plate 3 are connected by a support portion. The hollowed-out arrangement of the bottom plate 7 can reduce the weight of the bottom plate. In this embodiment, the specific shape of the hollowed-out portion is a rounded rectangle.

Specifically, in this embodiment, the support portion includes an upright support portion 10 , and a first inclined support portion 11 and a second inclined support portion 12 located on both sides of the upright support portion 10 . More specifically, the upright support portion 10 , the first inclined support portion 11 and the second inclined support portion 12 are arranged in a row, and the support portions are composed of multiple rows. The first inclined support portion 11 and the second inclined support portion 12 are inclined in opposite directions, and the distance between the first inclined support portion 11 and the second inclined support portion 12 on the bottom plate 7 is smaller than that on the top plate 2 . Such an arrangement may enable better support for the top plate.

Furthermore, the upright support portion 10 , the first inclined support portion 11 and the second inclined support portion 12 have cross-sections. With this arrangement, the upright support portion 10 , the first inclined support portion 11 and the second inclined support portion 12 have good rigidity and can provide better support.

Furthermore, a U-shaped protrusion 13 is provided on the side wall 1 of the base. The U-shaped protrusion 13 communicates with the deeper end of the groove portion 3 , and the opening direction of the U-shaped protrusion is upward. When the liquid falling on the top plate 2 flows out from the groove part 3, it can flow out from the U-shaped protrusion 13 and fall into the container placed under it.

Furthermore, support feet 8 are fixedly arranged on the bottom plate 7 , and recesses 9 are provided on the side wall 1 of the base at positions opposite to the support feet 8 . A fixing bolt is arranged on the ground, inserted into the through hole, and the base can be fixed with the ground through a nut. In this embodiment, the number of the supporting feet 8 is 8, and one side is 4.

Further, the supporting feet 8 are U-shaped, and the direction of the opening thereof faces the outside of the base. The location of the vias is within the U-shape, making it easier to locate.

Further, the base is T-shaped as a whole, and a mounting portion 15 is provided at the wider end. The mounting portion 15 is a column portion for mounting the CNC machine tool. And the deeper end of the groove portion 3 is located at the wider end of the base.

The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present invention without creative efforts. Therefore, any technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning or limited experiments on the basis of the prior art according to the concept of the present invention shall fall within the protection scope determined by the claims. .
