Description

Technical Field

[0001] This application relates to the field of shaft clamping flange technology, and more particularly to a shaft clamping flange device. Background Technology

[0002] A shaft clamping flange is a mechanical device used to connect shafts, typically used for equipment inlets and outlets or for connecting two pieces of equipment.

[0003] However, existing shaft clamping flanges do not have axial and radial limiting mechanisms, which can cause them to detach or slip when subjected to large axial forces or torques. Therefore, in order to correct the above defects, we propose a shaft clamping flange device. Summary of the Invention

[0004] In view of the above problems, this application provides a shaft clamping flange device to solve the problem of not having an axial limiting mechanism and a radial limiting mechanism.

[0005] This application provides a shaft clamping flange device, including a shaft and a rocker arm: a pair of positioning sleeves are fitted on the shaft, a pair of first screws pass through the upper positioning sleeve, and the top of the lower positioning sleeve has a threaded groove matching the first screws. A limiting tube is fitted on the pair of positioning sleeves, and a flange is fixedly connected to the right side wall of the limiting tube. A limiting groove is formed on the side wall of the flange, and a stop plate is provided in the limiting groove. A stabilizing tube is fixedly connected to the left side wall of the stop plate. The stabilizing tube is fitted on the shaft, and a plurality of second screws pass through the stop plate. The second screws pass through the stop plate and the stabilizing tube, and a spiral groove matching the second screws is formed on the side wall of the positioning sleeve.

[0006] In some embodiments, a pair of the first screws are symmetrically arranged about the central axis of the positioning sleeve.

[0007] In some embodiments, a first locking block is fixedly connected to the inner wall of a pair of positioning sleeves, and a first locking groove matching the first locking block is provided on the shaft.

[0008] In some embodiments, a pair of second locking blocks are fixedly connected to the inner wall of the limiting tube, and a pair of second locking slots that match the second locking blocks are provided on the positioning sleeve.

[0009] In some embodiments, the inner diameter of the stabilizing tube is equal to the diameter of the shaft.

[0010] In some embodiments, a pair of the first card blocks are symmetrical about the central axis of the shaft.

[0011] In some embodiments, a pair of the second card blocks are symmetrically arranged about the central axis of the positioning sleeve.

[0012] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0013] 1. By setting up the flange, limiting groove, blocking plate, stabilizing tube and second screw, the flange is prevented from moving to the left by the inclined surface on the left side of the positioning sleeve. When the flange is subjected to an axial force to the right, the blocking plate and the second screw can prevent the flange from moving to the right, thereby improving the radial stability of the flange.

[0014] 2. By setting the first locking block, positioning sleeve and first locking groove, the axial rotation of the positioning sleeve is prevented during the use of the flange. Furthermore, by setting the second locking block and second locking groove, the axial rotation of the flange and the limiting tube can be prevented, thereby improving the axial stability of the flange during use.

[0028] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0029] This application provides a shaft clamping flange device, including a shaft body 1 and a swing arm 15: a pair of positioning sleeves 2 are fitted on the shaft body 1, a pair of first screws 3 pass through the upper positioning sleeve 2, and the top of the lower positioning sleeve 2 is provided with a threaded groove that matches the first screws 3. A limiting tube 4 is fitted on the pair of positioning sleeves 2, and a flange 5 is fixedly connected to the right side wall of the limiting tube 4. A limiting groove 6 is provided on the side wall of the flange 5, and a stop plate 7 is provided in the limiting groove 6. A stabilizing tube 8 is fixedly connected to the left side wall of the stop plate 7. The stabilizing tube 8 is fitted on the shaft body 1, and a plurality of second screws 9 pass through the stop plate 7. The second screws 9 pass through the stop plate 7 and the stabilizing tube 8. A spiral groove 10 that matches the second screws 9 is provided on the side wall of the positioning sleeve 2.

[0030] In the technical solution of this application embodiment, the force is uniform, which improves the stability of the positioning sleeve 2. A pair of first screws 3 are symmetrically arranged about the central axis of the positioning sleeve 2. The axial rotation of the positioning sleeve 2 is prevented by the first locking block 11 and the first locking groove 12. The first locking block 11 is fixedly connected to the inner wall of the pair of positioning sleeves 2, and the shaft 1 is provided with a first locking groove 12 that matches the first locking block 11.

[0031] The swing arm 15 is connected to the flange 5 through a threaded hole on it.

[0032] In the technical solution of this application embodiment, the limiting tube 4 is limited to prevent the flange 5 from rotating. A pair of second locking blocks 13 are fixedly connected to the inner wall of the limiting tube 4, and a pair of second locking grooves 14 matching the second locking blocks 13 are opened on the positioning sleeve 2.

[0033] In the technical solution of this application embodiment, the stabilizing tube 8 is limited to improve the stability of the blocking plate 7. The inner diameter of the stabilizing tube 8 is equal to the diameter of the shaft 1. A pair of first locking blocks 11 are symmetrical about the central axis of the shaft 1, and a pair of second locking blocks 13 are symmetrical about the central axis of the positioning sleeve 2.

[0034] Working principle: In use, a pair of positioning sleeves 2 are placed on the shaft 1, and the first locking block 11 is engaged in the first locking groove 12. Then, the first screw 3 is tightened to fix the pair of positioning sleeves 2. Next, the limiting tube 4 is placed on the pair of positioning sleeves 2, and the second locking block 13 is engaged in the second locking groove 14. Then, the stabilizing tube 8 is inserted into the inner hole of the flange 5 and placed on the shaft 1. Then, the second screw 9 is tightened in the spiral groove 10 to fix the blocking plate 7 in the limiting groove 6 on the flange 5, thereby fixing the position of the flange 5. When the flange 5 is subjected to axial force, the flange 5 is prevented from dislodging to the right by several second screws 9, and the flange 5 is prevented from moving to the left by the inclined surface of the positioning sleeve 2. When the flange 5 is subjected to torque, the pair of positioning sleeves 2 is prevented from rotating by the first locking block 11, and the limiting tube 4 and the flange 5 are prevented from rotating by the second locking block 13, thereby improving the radial stability of the flange 5.
