Rotary worktable and high-speed numerical control reaming and honing machine tool with same

Abstract

The invention discloses a rotary worktable, and belongs to the technical field of reaming and honing machine tools. The rotary worktable comprises a driving unit, an output shaft, a rotary working disc, a cam and a rotary disc base, wherein the center of the rotary working disc is arranged on the rotary disc base through a rotating shaft; the driving unit is arranged below the rotary working disc and drives the rotary working disc to rotate through the rotating shaft, the output shaft rotates synchronously with the rotating shaft through gear mesh, the output shaft stretches out of the rotary disc base, and the cam is arranged on the output shaft; and each of one side of a transmission shaft and the lower portion of the rotary working disc is provided with one position sensor, the positions of the protruding edges on the two sides of the cam are recognized through the two position sensors, and operation of the driving unit is controlled. The rotary worktable is high in working efficiency and stable in machining quality, and the manual operation amount in the whole process is small, so that the safety coefficient is greatly increased; angular contact ball bearings and a tightening nut are adopted, so that the rotating precision of the transmission shaft is higher; and through rotary connection and the transmission shaft with a central water outlet flow channel, cutting fluid and disintegrating slag can be rapidly discharged, and a good cooling and lubricating effect is achieved so that the thermal deformation of a deep and long hole in the machining process can be reduced, and the machining precision is improved.

Description

technical field [0001] The invention relates to the technical field of reamer honing machines, in particular to a rotary worktable and a high-speed numerically controlled reamer honing machine tool with the same. Background technique [0002] The CNC reaming honing machine is a grinding machine that uses a honing head to honed the surface of the workpiece. It is mainly used for honing the holes of workpieces in manufacturing industries such as automobiles, tractors, hydraulic parts, bearings, and aviation. There are two types of reaming honing machine tools, vertical and horizontal. The main shaft of the vertical reaming honing machine tool has a short working stroke, which is suitable for honing cylinders and box holes. The honing head inlaid with oil stone is driven to rotate by the vertically arranged spindle, and at the same time it is driven by the hydraulic device to perform vertical reciprocating feed movement. The horizontal reaming honing machine has a long working...

Problems solved by technology

[0008] The object of the present invention is to provide a rotary table and a high-speed numerical control reaming honing machine tool with it, to solve the problems of safety and product quality when the traditional reaming honing machine tool is honing the workpiece proposed in the prior art, and can effectively prevent the rotary table from turning. In place, the tragic accident of collision between the tool and the workpiece due to different axes occurred, which not only ensures the safety of the CNC machine tool, but also makes batch processing safer and more reliable
