Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 3, a fixing device for shaft sleeve processing, which comprises a frame 1, the frame 1 is rotatably connected with a rotating shaft 2, a cavity 3 is arranged in the rotating shaft 2, a disc 4 is slidably connected in the cavity 3 in a left-right direction, a cone 5 is fixed at the right end of the disc 4, a plurality of sliding rods 6 are slidably connected in the radial direction and uniformly distributed on the rotating shaft 2, the sliding rods 6 are hinged with idler wheels 7 which are connected with the cone 5 in a rolling manner, a check block 8 which is positioned at the outer side of the rotating shaft 2 is fixed on the sliding rods 6, a spring 9 sleeved on the sliding rods 6 is installed between the check block 8 and the rotating shaft 2, a cylinder 10 is fixed in the cavity 3, the cylinder 10 is slidably connected with a piston rod 11, the other end of the piston rod 11 is fixedly connected with the.

The frame 1 is fixed with a motor 14, and the motor 14 is coaxially and fixedly connected with the rotating shaft 2.

The diameter of the cone 5 is reduced from left to right in turn.

In order to increase the friction coefficient, the slide bar 6 is fixed with an arc-shaped friction block 15 corresponding to the inner wall of the shaft sleeve workpiece 13.

When the utility model is used, the indication directions or position relations of the terms of front, back, left, right, up and down are based on the front view, when the shaft sleeve type workpiece with shorter length needs to be processed, the shaft sleeve workpiece 13 is sleeved on the outer surface of the rotating shaft 2, the left end of the shaft sleeve workpiece 13 is aligned with the right end of the baffle disc 12, then the air cylinder 10 is started, the air cylinder 10 drives the piston rod 11 to slide rightwards, the piston rod 11 drives the disc 4 to slide rightwards in the cavity 3, the disc 4 drives the cone 5 to slide rightwards, the diameter of the cone 5 is reduced from left to right, so that the diameter of the contact position of the roller 7 and the cone 5 is sequentially increased in the rightward sliding process of the cone 5, the cone 5 extrudes the roller 7, and the plurality of slide rods 6 are simultaneously far away from the central position of the rotating shaft 2 to slide radially, the spring 9 is in a stretching, when the slide bar 6 drives the arc-shaped friction block 15 to be tightly attached to the inner wall of the shaft sleeve workpiece 13, the inner wall of the shaft sleeve workpiece 13 is clamped and positioned, the air cylinder 10 is closed, the motor 14 is started, the motor 14 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the plurality of slide bars 6 to rotate together, the arc-shaped friction block 15 is tightly attached to the inner wall of the shaft sleeve workpiece 13, the arc-shaped friction block 15 drives the shaft sleeve workpiece 13 to rotate together, the turning processing of the shaft sleeve workpiece 13 is facilitated, the structure is novel, the cone 5 can control the slide bars 6 to extend out of different lengths, and further the shaft sleeve workpieces 13 with different inner diameters can be clamped, the application range is wide, the operation is simple, the fixing effect is good, after the processing is completed, the motor 14 is closed, the air cylinder 10 is started to reset, the cone 5 is reset in a, the flexibility is good.
