Problems solved by technology
A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. The existing clamping tools of the machine tool are all fixed at one end on the eight-station turret (spindle chuck or other clamping mechanism), and the other end is supported by a thimble. , but in the case of high-speed rotation or long-term use of the machine, it is easy to cause center deviation and insufficient rigidity, resulting in large errors in the workpiece produced by cutting

Embodiment
[0031] During use, one end of the workpiece to be processed is placed in the hydraulic chuck 20, (the eight-station turret 19 moves forward under the action of the X-axis servo motor 18 and the Z-axis servo motor 11, and one end of the workpiece is processed, processed After completion, the main shaft stops at a certain angle), the eight-station turret 19 retreats to a safe position, and the sub-spindle 17 is positioned according to the set angle and quickly moves to the processed workpiece end under the control of the Z-axis servo motor 11, clamping Hold the processed end, and at the same time the hydraulic chuck 20 is released, the sub-spindle 17 clamps the workpiece back to the sub-spindle 17 processing position, the eight-station turret 19 moves forward under the action of the X-axis servo motor 18, and the The unprocessed parts are processed, the spindle motor 1 of the left clamping device drives the spindle box 21 through the timing belt A 22 to rotate the hydraulic chuck...

The invention discloses a machine tool with a novel clamping mechanism, and belongs to the technical field of mechanical equipment. The machine tool comprises a base, a left clamping device and a right clamping device; the left clamping device and the right clamping device are arranged on the left side and the right side of the base; the left clamping device comprises a main shaft box and a main shaft motor; the right side of the main shaft box is connected with a hydraulic chuck; the right clamping device comprises a secondary main shaft, and a secondary main shaft rotating motor for drivingthe secondary main shaft to rotate; the left side of the secondary main shaft is connected with a cylinder clamping base for fixing mechanical parts; a positioning cylinder is arranged on the front side of the secondary main shaft; and eight-station cutter towers are arranged on the back sides of the left clamping device and the right clamping device. The machine tool has the beneficial effects ofhigh stability of workpieces in the machining process, low vibration and displacement in the cutting process, effective reduction of errors, increment of the cutting speed and the cutting quantity, reduction of the wear and improvement of the working efficiency and the machining quality.
Description
technical field [0001] The invention relates to a machine tool with a novel clamping mechanism, which belongs to the technical field of mechanical equipment. Background technique [0002] Machine tool (English name: machine tool) refers to a machine that manufactures a machine, also known as a machine tool or a machine tool, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing. In addition to cutting, there are casting, (casting) forging, welding, stamping, extrusion, etc., but for parts with high precision requirements and fine surface roughness requirements, generally All need to use the cutting method on the machine tool for final processing. A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. The existing clamping tools of the machine tool are all fixed...
