Embodiment Construction

[0014] figure 1 Is a schematic diagram of the structure of the present invention, figure 2 It is the left side view of the present invention. Combine figure 1 , 2 It can be seen that the new machine tool bed casting assembly includes an integrated casting molded chassis base 1 and an integrated casting molding workbench 2, wherein the top of the workbench 2 is provided with multiple T-slots 3, and the bottom of the chassis base 1 is provided with multiple mounting holes 17. A guide rail 4 is provided on the top of the chassis base 1, and the guide rail can be a V-static pressure guide rail with good shock absorption performance. A bracket 5 is provided in the middle of the chassis base 1, and an X-axis drive device 6 connected to the workbench 2 is provided on the bracket 5. The X-axis drive device 6 includes a workbench drive motor 7 and a rack 8 provided at the bottom of the workbench 2. , The table driving motor 7 is connected to the end of the worm 9 on the shaft, the wor...

Abstract

The invention relates to a novel machine tool bed casting assembly which comprises an integrally cast chassis base and an integrally cast working platform, wherein a plurality of T-shaped slots are arranged at the top of the working platform; a guide rail is arranged at the top of the chassis base, a support is arranged in the center of the chassis base, and an X-axis driving device connected with the working platform is arranged on the support; and a guide rail oil chamber is arranged at the bottom of the working platform, and the guide rail oil chamber is spaced on the guide rail. The novel machine tool bed casting assembly has the characteristics of reliable structure, good working stability, strong guide rail impact resistance, difficulty in wearing and the like. Because pressure oil is introduced between the guide rail and the working platform contact surface, a moving part is slightly floated, the friction factor is extremely small, the transmission efficiency is very high, and the crawling phenomenon can not occur during low-speed movement. Worms and gears are adopted for the X-axis transmission of the working platform, so that the working platform has the characteristics of large transmission ratio, smooth transmission and small noise. The novel machine tool bed casting assembly well solves the problems that the traditional working platform guide rail has poor impact resistance, is not applicable to heavy-load processing, is easy to wear and the like.

Description

Technical field [0001] The invention relates to a processing machine, in particular to a novel machine tool bed casting assembly. Background technique [0002] The machine bed is the foundation of the machine tool and a key part of the machine tool manufacturing. It is used to connect other parts, fix the workpiece, support the worktable, and achieve the effect of vibration reduction and anti-vibration. It bears a great weight and workpiece weight. The feed of the guide rail, the position relationship of each part, and the progress of the processing feed are all guaranteed by the bed, which must have sufficient rigidity, shock resistance, and wear resistance. Most of the existing machine tool bed castings are made by resin sand casting, which has the characteristics of high hardness, no heating, and high resin sand regeneration rate. It can save a lot of mold opening costs, shorten the production cycle, and has the advantages of good casting surface quality. [0003] The machine ...
