Description

Technical Field

[0001] This utility model relates to the technical field of coupling installation tools, specifically a coupling installation and calibration auxiliary device. Background Technology

[0002] A coupling, also known as a shaft coupling, is a mechanical component used to securely connect the driving shaft and driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts with other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are connected by keys or tight fits and fastened to the two shaft ends. The two halves are then connected together in some way. Couplings can also compensate for the misalignment (including axial misalignment, radial misalignment, angular misalignment, or combined misalignment) between the two shafts due to manufacturing and installation inaccuracies, deformation during operation, or thermal expansion; as well as mitigate shock and absorb vibration.

[0003] When installing a coupling, the center of the coupling needs to be aligned with the center of the driving or driven shaft. However, most existing couplings are installed manually by holding the coupling and aligning it with the driving or driven shaft. This process can easily cause the coupling to tilt, which affects the accuracy and stability of the installation. Therefore, those skilled in the art have proposed a coupling installation and calibration auxiliary device to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for coupling installation and calibration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A coupling installation and calibration auxiliary device includes a base, a movable groove at the top of the base, and first electric telescopic rods installed on the inner walls of both sides of the movable groove. Movable seats are installed at the adjacent ends of the two first electric telescopic rods. A fixed sleeve and a mounting base are connected to the top of the movable seats. A drive motor is installed inside the mounting base, and a drive gear is installed at the output end of the drive motor. A rotating cylinder is installed inside the fixed sleeve and can rotate within the fixed sleeve. A driven gear is installed on the outer wall of the rotating cylinder, and the drive gear meshes with the driven gear. Two clamping assemblies are symmetrically distributed at one end of the rotating cylinder.

[0006] As a further improvement of this utility model: both the inner wall of the fixed sleeve and the outer wall of the rotating cylinder are provided with annular grooves, and a number of rolling balls are provided in the annular grooves.

[0007] As a further embodiment of this utility model: the clamping assembly includes a second electric telescopic rod and a clamping plate mounted on the rotating cylinder, wherein the clamping plate is detachably mounted on one end of the second electric telescopic rod that extends into the rotating cylinder.

[0008] As a further improvement of this utility model: a mounting sleeve is connected to the center of the outer wall of the clamping plate, and the mounting sleeve is provided with a mounting hole on its side that cooperates with a bolt. The mounting sleeve is detachably mounted on one end of the second electric telescopic rod by means of a bolt.

[0009] As a further improvement of this utility model: an anti-slip pad is installed on the inner circumference of the clamping plate, and the anti-slip pad is fixed to the inner wall of the clamping plate by adhesive.

[0010] This utility model has the following advantages: The device adds a movable seat position through the first electric telescopic rod, making it easy for one end of the shaft to connect with one end of the coupling. The drive motor, drive gear, and driven gear work together to drive the rotating cylinder to rotate within the fixed sleeve. The rotating cylinder is equipped with a clamping assembly to clamp the shaft and coupling. In turn, the rotation of the rotating cylinder drives the shaft and coupling to rotate, which facilitates the adjustment of the connection and installation point between the shaft and the coupling. It is convenient for workers to install one end of the shaft and one end of the coupling together. The overall device has a simple structure and is easy to operate. It can ensure the stability of the shaft and coupling during installation and has greater practicality. Attached Figure Description

[0018] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0019] Example 1: Please refer to Figures 1 to 3 A coupling 21 installation and calibration auxiliary device includes a base 1. The top of the base 1 is provided with a movable groove 2. The inner walls of both sides of the movable groove 2 are each equipped with a first electric telescopic rod 3. A movable seat 4 is installed at one end of the two first electric telescopic rods 3 that are close to each other. The top of the movable seat 4 is connected to a fixed sleeve 8 and a mounting seat 5. A drive motor 6 is installed in the mounting seat 5. A drive gear 7 is installed at the output end of the drive motor 6. A rotating cylinder 9 is installed in the fixed sleeve 8. The rotating cylinder 9 can rotate within the fixed sleeve 8. A driven gear 10 is installed on the outer wall of the rotating cylinder 9. The drive gear 7 meshes with the driven gear 10. Two clamping components 13 are symmetrically distributed at one end of the rotating cylinder 9.

[0020] Please see Figure 1 , Figure 2The inner wall of the fixed sleeve 8 and the outer wall of the rotating cylinder 9 are both provided with annular grooves 11. Several balls 12 are provided in the annular grooves 11. The bottom end of the fixed sleeve 8 is connected to the top end of the movable seat 4 through a vertical rod. This structure makes the fixed sleeve 8 a bearing-like structure, which facilitates the rotation of the rotating cylinder 9 within the fixed sleeve 8.

[0021] Example 2: See Figures 1 to 3 Based on Embodiment 1, the clamping assembly 13 includes a second electric telescopic rod 14 and a clamping plate 15 mounted on the rotating cylinder 9. The clamping plate 15 is detachably mounted on one end of the second electric telescopic rod 14 that extends into the rotating cylinder 9. An installation sleeve 16 is connected to the center of the outer wall of the clamping plate 15. The side of the installation sleeve 16 is provided with an installation hole 18 that mates with a bolt 17. The installation sleeve 16 is detachably mounted on one end of the second electric telescopic rod 14 by the bolt 17. When clamping shafts 20 and couplings 21 of different shapes and sizes, the clamping plate 15 of the corresponding size can be replaced. The clamping plate 15 is arc-shaped.

[0022] Please see Figure 1 , Figure 2 The clamping plate 15 is equipped with an anti-slip pad 19 on its inner circumference. The anti-slip pad 19 is fixed to the inner wall of the clamping plate 15 by adhesive. The models of the drive motor 6, the first electric telescopic rod 3, and the second electric telescopic rod 14 can be selected from the prior art.

[0023] Working principle: In use, the drive motor 6, the first electric telescopic rod 3, and the second electric telescopic rod 14 are all connected to the external control circuit. The shaft 20 and the coupling 21 are placed in the two rotating cylinders 9 respectively. The second electric telescopic rod 14 drives the clamping plate 15 to move to clamp and fix the shaft 20 and the coupling 21. Then, the first electric telescopic rod 3 drives the two movable seats 4 to move closer to each other, thereby adjusting the end positions of the shaft 20 and the coupling 21. The drive motor 6 drives the drive gear 7 to rotate, which in turn drives the driven gear 10 to rotate, which in turn drives the rotating cylinder 9 to rotate, thereby driving the shaft 20 and the coupling 21 to rotate, so as to facilitate the combination and installation of the shaft 20 and the coupling 21.
