detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The utility model discloses a multifunctional five-axis machine tool turntable, through which a plurality of workpiece placement tables can work synchronously, sequentially clamp a plurality of identical workpieces for synchronous processing, and improve processing efficiency. The five-axis machine tools currently on the market are generally cutting-based. Considering the cutting range, the general turntable is designed to be relatively large, and there is only one turntable to meet the clamping and cutting requirements of various workpieces. However, many industrial products have the characteristics of small size, high processing requirements, small cutting volume, and large batches of processed products. It is obviously difficult to meet the requirements of production efficiency by using five-axis machine tools on the market. Therefore, it is necessary to reduce the number of turntables of the five-axis machine tool and increase the number. At the same time, the cutting power of the spindle is reduced and the number is increased. Using the motion properties of the five-axis machine tool, five workpieces can be processed simultaneously.

Referring to Figures 1 to 5, we will describe in detail the structure of the multifunctional five-axis machine tool of the present invention. a main shaft 30, and a workpiece placement table 20 is fixed on the top of each main shaft 30; the inside of the housing 10 is provided with a driving device 101, a screw mandrel 102, a screw nut 103, a guide rail 104, a guide rail slider 105, and a rack 106. and a plurality of gears 107; the driving device 101 is used to drive the screw 102 to rotate, and the screw nut 103 is arranged on the screw 102; the rack 106 is fixedly connected to the guide rail 104, and the The guide rail 104 is slidably arranged on the guide rail slider 105, and the guide rail 104 is also fixedly connected to the screw nut 103; each of the main shafts 30 is correspondingly fixed in a gear 107, and the gear 107 Both are meshed with the rack 106, and the gear 107 and the main shaft 30 are driven to rotate by the rack 106.

Further, the multifunctional five-axis machine tool turntable includes at least four main shafts 30 and the same number of gears 107 as the main shafts 30; and as a preferred embodiment, the multifunctional five-axis machine tool turntable includes five main shafts 30 and five 107 gears.
