Description

Technical Field

[0001] The utility model relates to the technical field of stepping motors, in particular to a highly compatible interface adapter for a stepping motor shaft. Background Art

[0002] An interface adapter for a motor shaft is an adapter used to connect a motor shaft to other devices or components. It allows the motor shaft to be connected to other devices according to specific interface standards, thereby realizing the effective connection and function realization between the motor and other devices. There are various types of interface adapters for motor shafts. According to different application scenarios and requirements, the design and specifications of the adapters will also vary.

[0003] Generally, an interface adapter for a motor shaft is designed only for one or two specific shaft diameters or interface types and cannot be flexibly applied to various motors or load devices on the market. Ordinary adapters often lack sufficient adjustment mechanisms and cannot effectively compensate for the possible slight misalignment between shafts, thus causing additional vibration and noise. Long-term operation will also exacerbate equipment wear and shorten the service life. Some adapters with fixed designs bring inconvenience to on-site operations, especially in places with limited space or where the equipment is already installed in place, increasing the installation difficulty, prolonging the maintenance time, and affecting production efficiency. Content of the Utility Model

[0004] In order to overcome the shortcoming that a general interface adapter for a motor shaft cannot be applied to various different shaft diameters, the purpose of the utility model is to provide a highly compatible interface adapter for a stepping motor shaft that is applicable to various different shaft diameters.

[0005] A highly compatible interface adapter for a stepping motor shaft includes a first fixing plate, a first shaft sleeve, a reinforcing rod, a second fixing plate, and a buffer assembly. A buffer assembly is connected to the right side of the first fixing plate. The second fixing plate is connected to the right side of the first fixing plate through the buffer assembly. First shaft sleeves are fixedly connected to the mutually remote sides of the first fixing plate and the second fixing plate. The mutually remote sides of the left and right first shaft sleeves are both open. Thread grooves are formed on both the left and right first shaft sleeves. Reinforcing rods are threadedly connected to both the left and right first shaft sleeves through the thread grooves.

[0006] Optionally, the buffer assembly includes a first nut, a first screw rod, a second screw rod, a second nut, and a rubber block. At least one rubber block is circumferentially and contactingly connected to the left side of the first fixing plate. The first screw rod and the second screw rod are inserted into each rubber block. The first screw rod is slidably connected to the second fixing plate. A first nut is threadedly connected to the first screw rod. At least one through hole is formed in the first fixing plate in the circumferential direction. The second screw rods all pass through the through holes. The second screw rods are slidably connected to the second fixing plate. A second nut is threadedly connected to the second screw rod.

[0007] Optionally, the buffer assembly further includes a buffer piece and a limit piece. One end of the second screw rod close to the through hole of the first fixed disk is fixedly connected with the buffer piece. The buffer piece is located in the through hole of the first fixed disk. Limit pieces for limiting the rubber blocks are fixedly connected to one sides of the first screw rods away from the first fixed disk.

[0008] Optionally, the buffer assembly further includes a gasket. Gaskets for fastening the first screw rod and the second screw rod are slidably connected to the first screw rod and the second screw rod.

[0009] Optionally, it further includes a second bushing and a pin. Second bushings are slidably connected inside the first bushings. The second bushings are plugged and connected with the reinforcing rods. The reinforcing rods all pass through the second bushings. First jacks are circumferentially formed on one sides of the left and right second bushings away from each other. Second jacks are circumferentially formed on one sides of the left and right first bushings away from each other. The second jacks are communicated with the first jacks. The second jacks are plugged with pins through the first jacks.

[0010] Optionally, it further includes a guide block. The guide block is fixedly connected to the outer wall of the second bushing. A guide groove adapted to the guide block is formed on the inner wall of the first bushing.

[0011] The utility model has the following advantages: By arranging the second bushing and the reinforcing rod, the utility model can enable rotating shafts of different sizes to be placed into the second bushing and then fixed by the reinforcing rod. And through the buffer assembly, the vibration and impact during the use of the utility model can be reduced, thereby improving the stability of the utility model during use. And a buffer piece is arranged in the buffer assembly, which can reduce the friction between the second screw rod and the first fixed disk. Description of the Drawings

Detailed implementation mode

[0018] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] A highly compatible interface adapter for a stepping motor shaft, as Figures 1-5 shown, comprising a first fixed disk 1, a first bushing 2, a reinforcing rod 3, a second fixed disk 11 and a buffer assembly. The buffer assembly is connected to the right side of the first fixed disk 1, and the second fixed disk 11 is connected to the right side of the first fixed disk 1 through the buffer assembly. Fixedly connected to the mutually remote sides of the first fixed disk 1 and the second fixed disk 11 are first bushings 2. The mutually remote sides of the left and right first bushings 2 are both open, and the openings of the first bushings 2 are both circular. Threaded grooves 31 are formed in both the left and right first bushings 2, and both the left and right first bushings 2 are threadedly connected to a reinforcing rod 3 through the threaded grooves 31. A flat notch is provided on the side of the reinforcing rod 3 away from the first bushing 2, enabling the use of a flat screwdriver to rotate and adjust the reinforcing rod 3. When using this interface adapter, the two rotating shafts of the device are respectively inserted into the left and right first bushings 2, and then the reinforcing rod 3 is rotated and tightened to squeeze the rotating shafts, thereby fixing the two rotating shafts in the left and right first bushings 2 respectively through the reinforcing rod 3. It can be applicable to rotating shafts with a diameter smaller than the inner diameter of the first bushing 2, and during the rotation process of this interface adapter, the buffer assembly can reduce vibration and impact.

[0020] Such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the buffer assembly includes a first nut 7, a first screw 8, a second screw 10, a second nut 12, and a rubber block 9. Five rubber blocks 9 are circumferentially and contact-connected to the right side of the first fixed disk 1. The first screw 8 and the second screw 10 are inserted into each rubber block 9. The first screw 8 is slidably connected to the second fixed disk 11, and the second screw 10 is slidably connected to the second fixed disk 11. A first nut 7 is threadedly connected to each first screw 8. Five through holes are circumferentially formed in the first fixed disk 1. The second screw 10 passes through the through holes, and a second nut 12 is threadedly connected to each second screw 10. During the use of this interface adapter, the buffer assembly makes the first fixed disk 1 and the second fixed disk 11 be flexibly connected. The rubber block 9 can absorb the impact load generated when the device starts or suddenly changes speed, reduce the instantaneous impact on the transmission shaft and bearings, and extend the service life of the entire transmission system. When the rubber block 9 needs to be replaced, rotate and unscrew the first nut 7 and the second nut 12, remove the first screw 8 and the second screw 10, and then insert the new rubber block 9 into the first screw 8 and the second screw 10.

[0021] As Figure 2 and Figure 5 shown, the buffer assembly further includes a buffer piece 101 and a limit piece 81. A buffer piece 101 is fixedly connected to one end of the second screw 10 close to the through hole of the first fixed disk 1. The buffer piece 101 is made of rubber and is located in the through hole of the first fixed disk 1. A limit piece 81 for limiting the rubber block 9 is fixedly connected to the side of the first screw 8 away from the first fixed disk 1. The limit piece 81 is made of iron. When the rubber block 9 is inserted into the first screw 8 and the second screw 10, the limit piece 81 can prevent the rubber block 9 from falling out of the first screw 8, thereby fixing the rubber block 9. The buffer piece 101 can reduce the friction between the second screw 10 and the first fixed disk 1, thereby protecting the second screw 10 and the first fixed disk 1.

[0022] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the buffer assembly further includes a gasket 13. The gasket 13 is made of circular iron. Gaskets 13 for fastening the first screw 8 and the second screw 10 are slidably connected to the first screw 8 and the second screw 10. The left gaskets 13 are located between the first screw 8 and the first fixed disk 1, and the right gaskets 13 are located between the second screw 10 and the second fixed disk 11. When the first nut 7 and the second nut 12 are tightened, the gasket 13 can make the installation of the first screw 8 and the second screw 10 more stable.

[0023] As Figure 2 and Figure 3As shown in the figure, it further includes a second bushing 4 and a pin 5. A second bushing 4 is slidably connected inside each of the first bushings 2. The open ends of the left and right second bushings 4 are arranged on the sides facing away from each other. The second bushing 4 is connected to the reinforcing rod 3 in a plug-in manner. The reinforcing rods 3 all pass through the outer wall of the second bushing 4. First insertion holes 41 are circumferentially formed on the sides of the left and right second bushings 4 facing away from each other. Second insertion holes 51 are circumferentially formed on the sides of the left and right first bushings 2 facing away from each other. The second insertion holes 51 are all communicated with the first insertion holes 41. Pins 5 are inserted into the first insertion holes 41. The pins 5 are connected to the second insertion holes 51 through the first insertion holes 41 in a plug-in manner. When the second bushing 4 needs to be used, the two second bushings 4 are respectively placed inside the first bushings 2 so that the first insertion holes 41 are all aligned with the second insertion holes 51. Then the pins 5 are inserted into the second insertion holes 51 through the first insertion holes 41. The two rotating shafts of the device are respectively inserted into the left and right second bushings 4, and then the rotating shafts are squeezed and fixed by the reinforcing rods 3, which can further increase the compatibility of this interface adapter, enabling smaller-diameter rotating shafts to be connected through this interface adapter.

[0024] As Figure 3 shown in the figure, it further includes a guide block 6. The guide block 6 is fixedly connected to the outer wall of the second bushing 4. Guide grooves 61 adapted to the guide block 6 are formed on the inner walls of the first bushing 2 and the second bushing 4, which can clamp a smaller bushing through the guide grooves 61 inside the second bushing 4. When the second bushing 4 is placed inside the first bushing 2, first align the guide block 6 with the guide groove 61, and then move the second bushing 4 to place it inside the first bushing 2, which can accelerate the installation of the second bushing 4 and ensure that the first insertion hole 41 is accurately aligned with the second insertion hole 51.

[0025] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
