[0002] The light machine is the low -end product of numerical control machine tool, relative to numerical control system etc. machine tool core part, the technical content is lower. However, this does not mean that the light machine is very easy to manufacture. The design and manufacturing process level of light machine is directly related to the quality, life and reliability of numerical control machine tool, requires that the production enterprise has very high technology and management level.

[0003] When the numerical control light machine is processing parts, the parts need to be placed on the processing platform and fixed, and the processing platform and the processing components can be moved at any time according to the actual processing requirements during the processing operation. However, the three-axis feeding direction of the traditional light machine is prone to limit in actual operation experiment, especially the installation angle and movement direction of the processing platform will produce processing blind area, which needs to be adjusted constantly. In this state, the processing precision and efficiency cannot be guaranteed. UTILITY MODEL CONTENT

[0004] The utility model discloses a three-axis feeding structure for numerical control light machine, which can solve the problems of the traditional light machine, such as the three-axis feeding direction being prone to limit in actual operation experiment, the processing precision and efficiency being not guaranteed during the process of constantly adjusting the installation angle and movement direction of the processing platform to produce processing blind area.

[0005] The utility model discloses a three-axis feeding structure for numerical control light machine, which can solve the problems of the traditional light machine, such as the three-axis feeding direction being prone to limit in actual operation experiment, the processing precision and efficiency being not guaranteed during the process of constantly adjusting the installation angle and movement direction of the processing platform to produce processing blind area.

[0006] The main shaft feeding structure, the base feeding structure and the processing platform feeding structure jointly constitute a three-axis feeding structure. The feeding direction of the base feeding structure is a horizontal feeding direction, the feeding direction of the processing platform feeding structure is a vertical feeding direction, and the installation direction of the processing platform feeding structure is a horizontal installation direction. This three-axis feeding structure will not be limited during the movement and feeding process, thereby avoiding the generation of processing blind area.

[0007] Further, the bed base includes a support foot, and the support foot is provided with a seat body. The seat body is directly connected to the bed column and supports the base feeding structure.

[0008] Further, the main shaft feeding structure comprises a main shaft sliding rail, a main shaft sliding block slidably connected to the main shaft sliding rail, a main shaft box mounting plate mounted on the main shaft sliding block, a main shaft box mounted on the main shaft box mounting plate, a machining head mounted at an end of the main shaft box, and a main shaft screw rod arranged at a middle position of the main shaft sliding rail and penetrating through the main shaft box mounting plate, wherein a main shaft control motor is arranged above the main shaft screw rod and fixed to a top of the column of the bed body.

[0009] Further, the base feeding structure comprises a fixed plate, base feeding sliding rails fixed to both sides of the fixed plate, base feeding sliding blocks slidably connected to the base feeding sliding rails, a base sliding plate mounted on the base feeding sliding blocks, and a base feeding screw rod arranged at a middle position of the base feeding sliding rails and penetrating through the base sliding plate, wherein a base control motor is arranged at an end of the base feeding screw rod and fixed to the fixed plate.

[0011] Beneficial effects: 1. The base feeding structure is installed in a horizontal direction, which ensures that the machining platform feeding structure moves horizontally. In a three-axis feeding structure, the base feeding structure controls the movement range, which is usually large. Before fine machining, the position of the clamped workpiece needs to be adjusted. This step requires the machining platform to have a maximum range of movement space. The horizontal installation direction can meet this requirement. Since the movement direction of the base feeding structure is parallel to the column of the bed body, there is no problem of position conflict and limitation with the column of the bed body during movement.

[0012] 2, the installation direction of the machining platform feeding structure is longitudinal installation, the action of the structure is to fine adjust the position of the clamped workpiece on the machining platform to ensure the machining precision, and since the control direction of the main shaft feeding structure can only move up and down, the machining platform is further required not to move in a large range to avoid exceeding the working range of the machining head, the machining platform feeding structure can perfectly control the machining position of the machining platform and the machining head to match, this part does not need to move in a large range, only needs to move in a small range in the longitudinal direction, although the longitudinal installation position is perpendicular to the bed column, but will not appear the limiting problem under the small range movement, is suitable for position fine adjustment;

[0013] 3, the machining platform installed in the transverse direction has enough space for fine adjustment of the position of the clamped workpiece under the premise of ensuring the design size, since the longitudinal installation will inevitably affect the fine adjustment space of the position if the design size is ensured, and the transverse installation will not have the problem.
