Referring to fig. 1, an encoder housing coupling mechanism mainly includes: a fixing frame 30 provided at a side of a motor (not shown) and carrying the encoder 10 at the same time, and a synchronous driving unit 40 provided in the fixing frame 30 to connect the motor spindle 20 and the encoder 10 for transmission.

Referring to fig. 2, the fixing frame 30 has a protrusion 33 extending outwards laterally, the protrusion 33 is further provided with a long groove 34 pointing to the axis of the fixing frame 30, and the long groove 34 enables the fixing frame 30 with one size design to be matched with a plurality of motors with different types for fixing. The protrusions 33 cooperate with fastening means with one to two fixing points on the same line, preventing the follow-up torsion of the fixing frame 30 when rotating along with the step driving unit 40.

Referring to fig. 3, the synchronous drive unit 40 is connected to the main shaft 20 through a first end 43 thereof and to the output shaft 11 of the encoder 10 through a second end 44. The joint 41 is disposed between the first end 43 and the second end 44 in connection with the bearing 50. The joint 41 has a ring 42 on the side near the first end 43, a second fastening member 46 is screwed on the side near the second end 44, and a gap 47 for accommodating a spring washer 46a is left between the second fastening member 46 and the joint 41, so that the synchronous drive unit 40 rotates inside the fixed frame 30 through a bearing 50. Preferably, the engaging portion 41 is in clearance fit with the bearing 50 in the radial direction, so that the assembly is facilitated.

Referring to fig. 4, the fixing frame 30 is formed by a frame 31 as a bearing body, the ends of both sides of the frame 31 are respectively provided with a first opening 35 and a second opening 36, the second opening 36 is used for setting the encoder 10, the synchronous driving unit 40 extends outwards from the first opening 35 to be connected with the main shaft 20, and the side part of the frame 31 is also provided with an operation window 32 for adjusting the installation of the synchronous driving unit 40.

Referring to the assembly illustration of fig. 5 in combination, the ring 42 is in close proximity to the inner race of the bearing 50, and the second fastener 46 engages the spring washer to engage the ring 42 to compress the bearing 50 from both sides for securement. The first end 43 is secured to the spindle 20 in a form-fitting relationship, and a first fastener 45 is provided between the spindle 20 and the ring 42. The second end 44 is connected to the output shaft 11 by a fastener 60, preferably a coupler. The side of the second end 44 is also cut with a boss 44a for connection to different types of couplings. The encoder 10 is fixed to one side of the second opening 36 by a fastener. The bearing 50 employs deep groove ball bearings to accommodate high rotational speed operating scenarios. The core point of the utility model is that the second opening 36 is coaxial with the bearing 50 and the synchronous drive unit 40, so that the encoder 10 can be quickly arranged coaxially with the spindle 20 by this mechanism.
