[0021] The utility model is further described below in conjunction with embodiments.

[0022] pass Figure 1-Figure 6It can be seen that the hydraulic swing cylinder with encoder is provided with a swing cylinder body 1, and the front end position and the rear end position of the swing cylinder body 1 are respectively provided with a front end fixing seat 2 and a rear end fixing seat 3.

[0023] A main shaft 10 is provided inside the swing cylinder body 1, and an encoder 7 is fixedly provided at the front end of the main shaft 10. An axial encoder connecting hole 5 is provided at the front end of the main shaft 10. A rotation detection shaft 11 is provided on the encoder 7. The other end of the rotation detection shaft 11 is fixedly connected to the encoder connecting hole 5. When the main shaft 10 rotates, the rotation detection shaft 11 is driven to rotate synchronously. The encoder 7 collects the rotation angle of the rotation detection shaft 11 in real time and then transmits it to the detector. The operator can understand the operating status of the swing cylinder at the first time.

[0024] An encoder fixing seat 4 is provided on the outside of the encoder 7, one end of the encoder fixing seat 4 is fixedly connected to the outside of the encoder 7, and the other end of the encoder fixing seat 4 is fixedly connected to the front end fixing seat 2. The encoder fixing seat 4 is used to fix the encoder 7 to prevent the encoder 7 from shaking when the main shaft 10 rotates, thereby affecting the accuracy of the encoder 7 detection. In addition, the encoder fixing seat 4 can also prevent foreign objects such as dust and particles in the workplace from causing damage to the encoder.

[0025] A connecting sleeve 8 is provided at one end of the rotation detection shaft 11 close to the encoder connecting hole 5, and the rotation detection shaft 11 is fixedly connected to the inner hole of the connecting sleeve 8. A connecting shaft 9 is provided at the other end of the connecting sleeve 8, and the connecting shaft 9 is fixedly connected to the inner hole of the connecting sleeve 8, and the other end of the connecting shaft 9 is fixedly connected to the encoder connecting hole 5.

[0026] Specifically, the encoder connecting hole 5 is a threaded hole, the connecting shaft 9 is provided with an external thread, and the connecting shaft 9 and the encoder connecting hole 5 are threadedly fixed and locked.

[0027] The inner hole of the connecting sleeve 8 is a threaded hole, and the rotation detection shaft 11 is provided with an external thread. The two ends of the connecting sleeve 8 are respectively threadedly fixed and locked with the connecting shaft 9 and the rotation detection shaft 11.

[0028] By using threaded locking between the rotation detection shaft 11 and the connecting sleeve 8, when the encoder 7 needs to be repaired or replaced with an encoder 7 of a different specification, the encoder 7 can be quickly disassembled and assembled, which is convenient to operate and saves time.

[0029] By using threaded locking between the connecting sleeve 8, the connecting shaft 9, and the encoder connecting hole 5, it is possible to adapt to hydraulic swing cylinders with encoder connecting holes 5 of different specifications by replacing connecting shafts 9 of different specifications, such as different aperture sizes and shapes of the encoder connecting holes 5, thereby achieving quick assembly and quick maintenance and saving time.

[0030] A through hole is provided on the encoder fixing seat 4 at the position where it is connected to the front end fixing seat 2, and a threaded hole 6 is provided on the front end fixing seat 2. The encoder fixing seat 4 is threadedly locked by a locking screw 13 passing through the through hole 14 and the threaded hole 6 on the front end fixing seat 2, so that the encoder fixing seat 4 and the front end fixing seat 2 are fixedly connected. Through the threaded locking method, the encoder fixing seat 4 can be quickly disassembled and assembled, saving operation time.

[0031] An axial encoder connecting hole 5 is provided at the rear end of the main shaft 10, and a threaded hole 6 is provided on the rear end fixing seat 3. When the encoder 7 cannot be installed at the front end of the main shaft 10 due to external obstacles, damage to the encoder connecting hole 5 at the front end of the main shaft 10, etc., the encoder 7 can be installed at the same position at the rear end of the main shaft 10 to avoid delays in normal working progress due to the inability to install and use the encoder, and enable the swing cylinder to operate in different terrain environments.

[0032] The encoder 7 can be connected to the monitor electrical signal via wireless signal transmission or using a communication line 12, and the operator can view the operation status of the swing cylinder in real time through the monitor.

[0033] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
