Numerical control lathe based on deep rotating and distance adjusting of high-speed claw tool for groove planing of gearbox cylinder cover

Abstract

The invention discloses a numerical control lathe based on deep rotating and distance adjusting of a high-speed claw tool for groove planning of gearbox cylinder cover. The numerical control lathe structurally comprises a human-computer interface screen, a double-column end tool holder, an inner lamp tube, a three-jaw chuck, a lathe bin door, a mechanical transmission case and a base bottom plate.According to the numerical control lathe, the double-column end tool holder is utilized to be matched with the three-jaw chuck, a double-drilling machining effect of a side thin blade and an inclinedplane cutter plate is formed, cutting the cylinder diameter is carried out on the cylinder cover deep groove in a first step, and trimming the cylinder opening chamfer thread is sequentially carriedout in a second step, so that the embedment degree of the cylinder cover is enabled to be high, a bottom plate groove block abuts against the three-jaw chunk in a buckling manner and aligned with a gearbox shell in position, a same frequency effect of the measurement distance and the zooming vibration amplitude is formed through a vibration pad overturning rod, so that the rotation deviation amplitude is consistent, the wide-diameter large offset is directly reduced, the synchronous deviation is enabled to directly eliminate interference factors, the angular velocity and the linear speed machining propulsion effect of the same-amplitude deep rotation are realized according to the original size, and the stability of a rack and the internal heat value coefficient of the gearbox cylinder cover butt jointing lathe body motor piston are guaranteed to reach the standard.

Description

technical field [0001] The invention relates to a CNC lathe based on the planing groove of a gearbox cylinder head, and belongs to the field of CNC lathes. Background technique [0002] CNC lathe is an automatic programming and processing equipment for parts with multi-tool rotary deep planing and cutting. It is also fast and efficient for deep turning and cutting of gearbox cylinder head and cylinder groove. After the completeness of the gearbox is improved, the shortcomings of the current technology that need to be optimized are: [0003] The CNC lathe processing of the gearbox requires deep cutting of the multi-cylinder ports to fit the cylinder head thread butt joint, which prevents the tool holder offset on the lathe from vibrating too much, but the gearbox shell itself with the three-jaw chuck clamp has a high dead weight. The large range of rotary centrifugal shaking makes the horizontal feed and rotation of the tool post larger than the conventional cutting rotary d...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a CNC lathe based on the grooving of the gearbox cylinder head with high-speed claw knife deep-turning and pitch-adjusting, so as to solve the problem of deep cutting and laminating cylinders with multiple cylinder ports in the CNC lathe processing of the gearbox. The cover is threaded butt joint, so that the offset of the tool post on the lathe cannot be too large. However, the gearbox shell of the three-jaw chuck clamp has a high deadweight and a large range of centrifugal shaking, so that the tool post does not move when the tool is in and out. The rotation amount of the horizontal feed is larger than that of the conventional cutting rotation circle, which causes the depth and inner width of the cylinder mouth to become larger, which affects the friction coefficient and internal heat value of the piston rod in the piston cylinder. The slippage of the movement increases, the reciprocating driving force decreases, and the consumption of lubricating oil is too large, causing serious dimensional deviation problems to the deep groove of the cylinder head
