A cross guide slide and lead screw feeding mechanism, which cannot adjust the resistance at each position to ensure consistency, and will vibrate after a long period of use. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sliding sleeve feed structure with high precision, large load capacity and low vibration.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This application provides a sliding sleeve feed structure, including:

[0006] The turbine housing has an upper through hole and a lower through hole that pass through the front and back, respectively, in its upper and lower parts.

[0007] The sliding sleeve is slidably installed inside the lower through hole;

[0008] The bearing is fixedly installed in the upper through hole;

[0009] The ball screw nut is rotatably installed in the bearing hole of the bearing;

[0010] A ball screw is connected to the ball screw nut, and one end of the ball screw is fixedly connected to one end of the sliding sleeve;

[0011] A limiting component, which cooperates with the ball screw nut, is used to limit the axial movement of the ball screw nut relative to the ball screw;

[0012] A servo motor is fixedly mounted on the turbine housing, and the servo motor is connected to the ball screw nut.

[0013] Furthermore, the limiting assembly includes a round nut and a motor plate. The motor plate is fixedly mounted on the turbine housing, and the servo motor is fixedly mounted on the motor plate. A groove is formed on the inner side of the bottom end of the motor plate. One end of the bearing is abutted and mounted in the groove. The head of the ball screw nut is provided with a stepped portion and an external thread that are arranged oppositely. The stepped portion is located on the head of the ball screw nut near the end of the groove. One end of the ball screw nut is abutted and connected to the stepped portion. The round nut is threaded and fixedly mounted on the external thread. The round nut is abutted and connected to the other end of the bearing and the ball screw nut.

[0014] Furthermore, it also includes an active synchronizing pulley, a passive synchronizing pulley, and a timing belt.

[0015] Furthermore, it also includes a handwheel, which is fixedly connected to the active synchronizing wheel via a handle.

[0016] Furthermore, one end of the ball screw is fixedly connected to one end of the sliding sleeve via a flange.

[0017] The beneficial effects of this utility model are as follows:

[0018] By employing the aforementioned sliding sleeve feeding structure, a ball screw is fixedly connected to the sliding sleeve, and a limiting component is used to limit the ball screw nut mounted on the ball screw, preventing the ball screw nut from moving axially. The servo motor drives the ball screw nut to rotate. Since the ball screw nut cannot move axially, the ball screw that meshes with the ball screw nut can move forward or backward axially, thereby synchronously driving the sliding sleeve to move axially. During this process, the forward and backward movement of the sliding sleeve is achieved through the meshing of the ball screw and the ball screw nut. The meshing transmission between the ball screw nut and the ball screw has the characteristics of high transmission accuracy, good load capacity, and smooth transmission. Therefore, the sliding sleeve also has the characteristics of high accuracy, large load capacity, and low vibration during movement. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] See appendix Figure 1 To be continued Figure 4 As shown, this embodiment provides a sliding sleeve feed structure 100, including a worm gear box 1, a sliding sleeve 2, a bearing 11, a ball screw nut 17, a ball screw 13, a limit assembly, and a servo motor 10.

[0028] In this embodiment, refer to the appendix Figure 4 As shown, the upper part and lower part of the worm gear box 1 are respectively provided with an upper through hole 14 and a lower through hole 15. The upper through hole 14 and the lower through hole 15 are arranged in parallel and penetrate the front end face and the rear end face of the worm gear box 1.

[0029] Continue to refer to the appendix Figure 4 As shown, the sliding sleeve 2 is installed in the lower through hole 15 at the bottom of the turbine housing, and the outer wall of the sliding sleeve 2 is slidably connected to the inner wall of the lower through hole 15, that is, the sliding sleeve 2 can move back and forth relative to the lower through hole 15.

[0030] The ball screw 13 is mounted in the upper through hole 14 of the worm gear box 1 via a ball screw nut 17, which is installed in the bearing 11 hole of the bearing 11. In this embodiment, to ensure that the ball screw 13 can move axially back and forth, the ball screw nut 17 can only rotate. Therefore, in this embodiment, the ball screw nut 17 is limited to rotation by a limiting component.

[0031] See attached document Figure 4As shown, in this embodiment, one end of the ball screw 13 is fixedly connected to one end of the lower sliding sleeve 2, so that the ball screw 13, which is in a back-and-forth moving state, can synchronously drive the lower sliding sleeve 2 to move back and forth synchronously.

[0032] See attached document Figure 4 As shown, the power output by the servo motor 10 is transmitted to the ball screw nut 17, causing the ball screw nut 17 to rotate. Due to the limitation of the limiting component, the rotating ball screw nut 17 can only rotate, while the ball screw 13 meshing with it moves axially, that is, the ball screw 13 can move forward or backward. The ball screw 13 in the forward and backward movement state can synchronously drive the lower sliding sleeve 2 to move forward and backward. During the forward and backward movement of the sliding sleeve 2, since it is driven by the upper ball screw 13 to move synchronously, and the meshing transmission between the ball screw 13 and the ball screw nut 17 has the characteristics of high precision, smooth transmission and good load capacity, the movement of the sliding sleeve 2 also has the characteristics of high precision, smooth transmission and good load capacity.

[0033] See attached document Figure 4 and attached Figure 5 As shown, in this embodiment, the limiting component specifically includes a round nut 12 and a motor plate 4. The motor plate 4 is fixedly mounted on the turbine housing, and the servo motor 10 is fixedly mounted on the motor plate 4. A groove 41 is provided on the inner side of the bottom end of the motor plate 4. One end of the bearing 11 is abutted and installed in the groove 41. The head of the ball screw nut 17 is provided with a stepped portion 16 and an external thread. The stepped portion 16 is located on the head of the ball screw nut 17 near the end of the groove 41. One end of the ball screw nut 17 is abutted and connected to the stepped portion 16. The round nut 12 is threaded and fixedly mounted on the external thread. The round nut 12 is abutted and connected to the other end of the bearing 11 and the ball screw nut 17. That is, the left and right sides of the bearing 11 are limited and fixed by the round nut 12 and the groove 41 on the motor plate 4, respectively; the left and right sides of the ball screw nut 17 are limited and fixed by the round nut 12 and the stepped portion 16, respectively.

[0034] See attached document Figure 1 and attached Figure 4 As shown, in this embodiment, the ball screw 13 and the sliding sleeve 2 are fixedly connected by a flange 3, that is, the forward and backward movement of the ball screw 13 can be synchronously transmitted to the sliding sleeve 2 below through the flange 3.

[0035] See attached document Figure 1 and attached Figure 4As shown, in this embodiment, an active synchronous pulley 5 is fixedly installed on the output shaft of the servo motor 10, and a passive synchronous pulley 9 is fixedly installed at the tail of the ball screw nut 17. A synchronous belt 8 is installed between the active synchronous pulley 5 and the passive synchronous pulley 9. In this way, the power output by the servo motor 10 drives the passive synchronous pulley 9 to rotate through the active synchronous pulley 5 and the synchronous belt 8, and the passive synchronous pulley 9 in turn drives the ball screw nut 17 to rotate.

[0036] See attached document Figure 1 and attached Figure 4 As shown, a handwheel 7 is also provided at the other end of the active synchronous wheel 5 relative to the servo motor 10. The handwheel 7 is fixedly connected to the active synchronous wheel 5 via a handle 6. The handwheel 7 allows the sliding sleeve 2 to be started and stopped at any position. That is, by manually turning the handwheel 7, the handwheel 7 drives the active synchronous wheel 5 to rotate. The active synchronous wheel 5 then drives the ball screw nut 17 to rotate via the synchronous belt 8 and the passive synchronous wheel 9. The rotating ball screw nut 17 causes the ball screw 13 meshing with it to move back and forth. The back and forth movement of the ball screw 13 synchronously drives the sliding sleeve 2 below to move back and forth. Thus, by rotating the handwheel 7, the position of the sliding sleeve 2 can be adjusted, thereby achieving the purpose of starting and stopping the sliding sleeve 2 at any position.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
