Background
As shown in fig. 1 and 2, the encoder 100 is widely used in various industrial fields, and a common industrial encoder 100 is provided with an encoder fixing portion 110 at a bottom thereof, and the mounting portion 110 is provided with a mounting groove 111, where the mounting groove 111 is generally an annular groove. When the encoder 100 is fixedly installed, the encoder 100 is conventionally fixed by using a circular gasket having an annular gasket on the outer circumference, and the annular gasket has a fixing lug on the outer circumference, and the fixing lug is provided with a bolt hole. When the encoder 100 is fixedly installed, the annular gasket is located in the annular groove, and the fixing lug is connected to the bottom plate 200 through the bolt. The device has large jitter in the working state, so that the angle deviation and even the falling of the encoder are easily caused; the traditional fixing method has the advantages that the contact area between the gasket and the mounting groove is small, the pressing force is small, in the pressing process, part of the gasket is stressed, the other part of the gasket is in a suspended state, the stress is unstable, and the encoder can fall off for 3-4 times in a circle.
In addition, the angle of the encoder needs to be readjusted every time the encoder falls off, and only when the fixed angle position of the encoder is correct, the measured value is correct. The traditional fixing method causes that when the angle of the encoder is adjusted, the bolt has to be loosened, readjusted and fastened, if the adjustment fails, the bolt needs to be loosened repeatedly until the angle is correct, and a great deal of time and energy are wasted. .

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms such as "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and changes or modifications of the relative relationship may be made without substantial technical changes.
As shown in fig. 3, 5 and 6, an encoder mounting base in an embodiment of the present invention includes a mounting base body 300, the mounting base body 300 defines an accommodating hole 310 of an encoder fixing portion 110, a protruding engaging portion 320 is disposed on an inner sidewall of the accommodating hole 310, and the engaging portion 320 is adapted to the mounting groove 111 of the encoder fixing portion 110.
Taking the example of fixing the encoder 100 to the base plate 200, when the encoder 100 is mounted on the base plate 200, the engagement portion 320 is located in the mounting groove 111 of the encoder fixing portion 110, and is therefore restricted to the encoder mounting seat in the axial direction and the radial direction of the accommodating hole 310, and the encoder mounting seat is fixed to the base plate 200 by bolts. The accommodating hole 310 accommodates the encoder fixing portion 110, and the bottom end surface of the mount body 300 is attached to the base plate 200 and fixed to the base plate 200.
As shown in fig. 3 and 4, the catching portion 320 is an annular protrusion. The annular protrusion is confined in the annular groove of the mounting portion 110, and it can be ensured that the clamping portion 320 and the annular protrusion are uniformly stressed in the axial direction of the receiving hole 310. Meanwhile, the annular protrusion and the annular groove are matched tightly, but it is still ensured that the encoder fixing part 110 can still rotate in the accommodating hole 310 even if the encoder fixing part 110 is limited on the encoder mounting seat in the axial direction and the radial direction of the accommodating hole 310, and further the angle of the encoder 100 can be adjusted. Since the vibration of the machine is generally along the axial and radial directions of the receiving hole 310, interference with the circumferential movement of the encoder is relatively small, and thus the encoder 100 has a small possibility of being displaced by the machine vibration after the angular adjustment is completed.
As shown in fig. 4, the mounting base body 300 is formed by splicing a plurality of mounting base parts 330. Preferably, the mounting seat body 300 is of a half structure, and the mounting seat body 300 can be divided into two parts along a diameter, so that the manufacturing of the mounting seat body 300 is facilitated, and the installation of the encoder mounting seat for fixing the encoder 100 is facilitated.
As shown in fig. 5 and 6, the mount body 300 is made of nylon, which has many advantages such as high mechanical strength, good toughness, and strong shock and stress absorbing ability, and can absorb the vibration of the encoder from the machine body.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
