Abstract
An assembled main shaft unloading device of a numerically controlled lathe solves the problems of forced deformation of a main shaft and working vibration resulting from that a belt of an existing single-main shaft numerically controlled lathe radially draws the main shaft. The assembled main shaft unloading device is characterized in that an unloading sleeve (3) fixed onto a main shaft box body (2) through a fastening piece (7) is arranged at the tail end of a main shaft (1), a belt pulley (4) is mounted on and rotates round the unloading sleeve (3) through a pair of deep groove ball bearings (9), a shaft sleeve circular disk (5) is arranged between the belt pulley (4) and the main shaft (1), the end face of the circular disk is fixed onto the belt pulley (4), and a groove mounting flat key (6) is correspondingly arranged between the inner wall of a hole and the main shaft (1). The unloading sleeve fixed onto the main shaft box body bears all radial pulling force, thereby effectively avoiding vibration and even forced deformation during rotation of the main shaft, and greatly increasing processing precision of products.
Description
One, technical field
The utility model belongs to mechanical transmission, relates in particular to a kind of numerically controlled lathe assembled main shaft relief arrangement.
Two, background technology
The spindle of numerical control lathe case has frame modes such as single main shaft and two main shafts usually, numerically controlled lathe in the market much is to adopt single main axle structure, the main motor of this structure normally drives main axis rotation by the belt pulley of the direct drive installation of belt on main shaft, its radial pull acts directly on the machine tool chief axis, cause the flutter of machine tool chief axis stress deformation and lathe when work main shaft easily, thereby influence the operating accuracy of lathe.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, can eliminate the assembled main shaft relief arrangement of main shaft radial pull.
The technical solution of the utility model is: the tail end that stretches out the main shaft casing at main shaft is provided with an off-load cover, be fixed in by securing member on the axis hole end face of main shaft casing, belt pulley is installed in by a pair of deep groove ball bearing that off-load puts and can be around the rotation of off-load cover, between belt pulley and main shaft, be provided with an axle sleeve disk, this axle sleeve disk kink is on main shaft, its disk end face and pulley surface are fixedly connected by fastening bolt, correspondence is provided with groove flat key is installed on the axle sleeve hole inwall of axle sleeve disk and the main shaft, by this key axle sleeve disk rotatablely moving of belt pulley is passed to main shaft.
The beneficial effects of the utility model are: owing to be provided with an off-load cover and axle sleeve disk at the main shaft tail end, make belt pulley around the rotation of off-load cover, drive main axis rotation by flat key, the off-load cover has born whole radial pulls, thereby effectively prevent flutter even stress deformation in the main shaft rotation process, the machining accuracy of product is significantly promoted.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is at main shaft, and 2 is the main shaft casing, and 3 are the off-load cover, and 4 is belt pulley, and 5 is the axle sleeve disk, and 6 is flat key, and 7,8 is securing member, and 9 is deep groove ball bearing.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, choose metal material and make off-load cover 3 and axle sleeve disk 5, the internal orifice dimension of off-load cover 3 is greater than the main shaft 1 afterbody diameter of axle, and its end face is fixed in the screw of main spindle box axon hole end surface setting by fastening bolt 7, makes off-load cover 3 and main shaft casing 2 form one.The shaft hole diameter of axle sleeve disk 5 is slightly larger than main shaft 1 tail end diameter and takes movingly, and is provided with groove at shaft hole inner wall and main shaft tail end correspondence, places flat key 6 in groove, and has matched the tight degree of flat key control inspection.Belt pulley 4 is installed on the off-load cover 3 by a pair of deep groove ball bearing 9 and can rotates around it, and the disc surfaces of axle sleeve disk 5 is fixedlyed connected with the outer surface of belt pulley 4 by fastening bolt 8, and belt pulley 4 links to each other with belt pulley on the motor by belt.Enforcement of the present utility model is owing to transfer to the radial pull between belt pulley 4 and the motor fully on off-load cover 3 and the main shaft casing 2, drive pulley on the motor makes belt pulley 4 around 3 rotations of off-load cover by belt, drive axle sleeve disk 5 and rotate, be arranged at that the flat key 6 in the groove rotates main shaft 1 between axle sleeve disk 5 and the main shaft 1.This power of unloading constructional device makes main shaft no longer be subjected to the effect of belt radial pull and produces flutter even deform, and the product quality precision that numerically controlled lathe is produced is greatly enhanced.
Claims (1)
