Fully CNC Camshaft Milling Machine

Abstract

The invention discloses a full numerical control camshaft milling machine, which comprises a bed (9), a guide rail plate (10), a guide rail (19), a rotating power head (6), a milling power head (3) and a lifting power head (16), Rotary power heads are respectively arranged at both ends of the guide rail plate, hydraulic chucks (11) are arranged on the rotating power heads, and auxiliary supports (8) are arranged between the hydraulic chucks, and the milling power heads are arranged on the lifting platform, and the lifting platform (20) can move on the column (14). The milling power head includes the milling cutter spindle (23). The column can move left and right on the guide rail (19). An inertial balance wheel (27) or a milling cutter spindle is arranged on the milling cutter spindle. The main shaft is connected with the inertia balance wheel through the driven wheel (24) on the milling cutter main shaft. The milling cutter spindle of the present invention does not generate vibration, which not only reduces the processing noise, prolongs the service life of the milling cutter, but also improves the milling quality, reduces the reserved grinding amount, reduces the grinding workload, improves the processing efficiency, and reduces the Camshaft machining cost.

Description

Technical field [0001] The invention relates to camshaft processing equipment, in particular to a fully numerically controlled camshaft milling machine. Background technique [0002] As we all know, camshaft cam profiles are mostly processed by copying lathes. With the development of science and technology and the improvement of technological quality requirements, most of the camshaft camshaft machining has been replaced by a CNC camshaft milling machine with compact structure, good performance, no profiling, high machining efficiency, and strong applicability. However, the existing CNC camshaft milling machine still has the following problems in processing: First, the existing CNC camshaft adopts dual power head synchronous transmission, which is formed by the cross axle bridge transmission mechanism, and the cross axle bridge synchronous transmission Although the mechanism can achieve synchronization, its synchronization transmission accuracy is poor, the transmission structur...

Problems solved by technology

But the existing numerical control camshaft milling machine also has the following problems in processing: one is that the existing numerical control camshaft adopts double power head synchronous transmission, and the double power head synchronous transmission is formed by the cross shaft bridge transmission mechanism, and the cross shaft bridge synchronous transmission Although the mechanism can achieve synchronization, its synchronous transmission accuracy is poor, the transmission structure is more complicated, and the manufacturing and installation are troublesome, which increases the manufacturing cost of the milling machine and reduces the production efficiency; The plane range occupied by the front and rear movement of the guide rail is relatively large, which increases the floor area of ​​the workshop; and because the milling head is processed as intermittent cutting, it is affected by the cutting force during the machining process, and the speed of the milling cutter spindle is unbalanced, and the milling cutter spindle will generate Vibration is prone to broaching and tool collision, which not only increases the processing noise and reduces the service life of the milling cutter, but also affects the milling quality. The reserved grinding amount is more, which increases the grinding workload and reduces the grinding efficiency. Increased camshaft machining costs
