DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 3 The embodiment of the present application provides a multi-directional milling device for guide sleeve processing, including a frame 1, a moving device is installed on the frame 1, a milling device is installed on the moving device, a rotation drive device 2 is installed on the frame 1, the rotation drive device 2 can be a servo motor, a rotating frame 3 is installed on the output end of the rotation drive device 2, the moving device is located directly above the rotating frame 3, an electric cylinder 4 is installed on the rotating frame 3, a lifting plate 5 is installed on the output end of the electric cylinder 4, a slide groove 6 is provided on the lifting plate 5, two sliders 7 are slidably connected in the slide groove 6, a semicircular clamping block 8 is installed on the slider 7, the size of the semicircular clamping block 8 is adapted to the inner diameter of the guide sleeve, a linear actuator 9 is installed in the slide groove 6, and a linear actuator 9 is installed in the linear actuator 9. Actuator 1 9 can be a double-headed hydraulic cylinder with two telescopic ends that can be telescoped synchronously. The oil inlet and oil outlet of the double-headed hydraulic cylinder are connected to the hydraulic station through a connecting pipe, and the output end of linear actuator 1 9 is connected to the slider 7; two moving grooves 10 are provided on the rotating frame 3, and the moving grooves 10 are arranged opposite to each other. A moving block 11 is slidably connected in the moving groove 10, and an arc-shaped clamping plate 12 is installed on the moving block 11. The inner arc surface of the arc-shaped clamping plate 12 is adapted to the outer diameter of the guide sleeve. A linear actuator 2 13 is installed in the moving groove 10. Linear actuator 2 13 can be a hydraulic cylinder. The oil inlet and oil outlet of the hydraulic cylinder are connected to the hydraulic station through a connecting pipe, and the output end of linear actuator 2 13 is connected to the moving block 11.

[0020] In this embodiment, when the guide sleeve is milled, the hydraulic station gives pressure to the linear actuator 19, so that it drives the slider 7 sliding in the slide groove 6 to move outward, so that the inner wall of the guide sleeve is clamped and fixed by the semicircular clamping block 8 on the slider 7. After the fixing is completed, the outer cylindrical surface of the guide sleeve can be milled. After the milling is completed, the hydraulic station gives pressure to the linear actuator 213, so that it drives the moving block 11 sliding in the moving groove 10 to move, and the moving block 11 arranged oppositely drives the arc clamping plate 12 to fix the outer cylindrical surface of the guide sleeve. After the fixing is completed, the linear actuator 19 drives the slide 7, so that the semicircular clamping plate 8 no longer squeezes and fixes the inner wall of the guide sleeve. At the same time, the electric cylinder 14 drives the lifting plate 5 to move downward, so that the semicircular clamping block 8 moves downward, which does not affect the milling of the inner wall of the guide sleeve by the milling device.

When moving up and down, the limiting hole 17 on the frame 1 guides and limits the lifting frame 16 to avoid damage to the electric cylinder 2 15.

[0023] In some embodiments, in order to facilitate the milling of the guide sleeve, a milling device is provided including a motor 20, the motor 20 is mounted on the slide 19, and a milling cutter 21 is mounted on the output end of the motor 20. The moving track of the rotation center of the milling cutter 23 intersects with the rotation center line of the rotary drive device 2, so that the milling of different positions of the inner and outer circular surfaces of the guide sleeve can be achieved.
