Description

Technical Field

[0001] The utility model belongs to the technical field of encoder installation accessories and relates to an encoder fixing device. Background Art

[0002] The encoder is a signal feedback device commonly used in the production process. The encoder shaft is connected to the motor shaft through a flexible connection. The rotation of the motor shaft drives the encoder shaft to rotate, so that the encoder can monitor the movement state of the motor and realize servo, speed regulation and other functions. Figure 1 As shown, the flexible connection is located between the encoder and the motor, connecting the encoder bearing and the motor's rotating bearing, so that the encoder and the motor are in the same axis working state. The flexible connection is usually used to buffer the vibration shock transmitted from the motor's rotating bearing.

[0003] However, in the actual production process, the relative position between the encoder and the motor will shift when the encoder works for a long time, resulting in the encoder shaft and the motor shaft being out of sync. Long-term operation of the encoder in the absence of synchrotron radiation will cause the soft connection to break, causing serious impact on production and safety.

[0004] The existing solution is to install a fixture on the encoder to fix the encoder, so as to ensure that the encoder and the motor are in a coaxial working state. However, after the encoder is fixed, the existing fixture can only adjust the position of the encoder in a limited number of directions. When the axis offset is not in the adjustable direction, the encoder needs to be reinstalled and fixed. In addition, the existing fixture has high requirements for the installation position of the motor's moving axis and is very limited by the installation environment. In particular, when there is an angle between the motor's moving axis and the horizontal plane, the existing encoder fixture will not be able to meet the requirements and cannot adapt well to the actual production situation. Summary of the invention

[0005] The purpose of the utility model is to provide an encoder fixing device, through which the encoder can be flexibly fixed in multiple directions and angles, and the installation and adjustment are convenient and quick, which expands the application scenarios and improves adaptability.

[0008] The fixing plate is provided with a mounting hole for the encoder connecting shaft to pass through, and is also provided with a plurality of fixing holes for fixing the encoder on the fixing plate;

[0012] The second rotating plate is detachably fixedly connected to the fixed support member group.

[0013] As a limitation, the fixing holes are distributed around the mounting hole.

[0014] As a second limitation, the fixed support member group includes a vertical long strip first support frame, and the first support frame is provided with a first strip hole along the length direction of the first support frame;

[0016] As a further limitation, the fixed support member group further includes a horizontal long strip second support frame, and the second support frame is provided with a second strip hole along the length direction of the second support frame;
