Description

An adjustable encoder mounting mechanism Technical Field

[0001] This utility model relates to an adjustable encoder mounting mechanism, belonging to the field of encoder technology. Background Technology

[0002] An encoder is a component in motion control systems and an important device widely used in computer communication, automation control, and industrial automation. Encoders convert analog or digital signals into digital codes, which are then fed back to the actuator to achieve precise speed and position control. An encoder typically consists of a rotating part and a stationary part. The rotating part follows the rotation of the object being detected, while the stationary part is attached to the stationary object. The encoder converts the displacement caused by the rotation of the rotating part into a digital signal, thereby enabling the measurement and control of the object. This helps manufacturers produce high-quality parts or move objects quickly and smoothly from one point to another.

[0003] Encoders, as information acquisition elements for detecting the operating status of an object, are generally connected to the object being detected via mechanical mounting. The object being detected is typically a rotating shaft. In most cases, an encoder mounting bracket needs to be installed at a suitable position at the end of the rotating shaft to secure the encoder, and a flexible coupling is used to connect the encoder end shaft and the rotating shaft. During coupling installation, any form of misalignment error can lead to undesirable consequences, particularly by subjecting the coupling to avoidable stresses, which can eventually cause tearing or damage to the coupling material. To ensure the effectiveness and safety of the rotating shaft rotation and the data acquisition system operation, the coaxiality of the encoder end shaft and the rotating shaft is crucial. The encoder and rotating shaft must be installed concentrically; any deviation can cause the mechanical load on the encoder shaft to exceed the rated range, thereby shortening the encoder's service life.

[0004] Therefore, encoder mounting brackets require strict machining precision and geometric tolerances to ensure concentricity between the encoder and the rotating shaft. However, in commonly used encoder mounting structures, the coaxiality between the encoder, coupling, and rotating shaft is difficult to adjust during installation, and the adjustment range is limited. This can easily lead to coupling tearing and damage due to misalignment after installation, as well as a shortened encoder lifespan. Furthermore, some customers' on-site equipment was not designed with encoders for control and measurement in mind. For encoders that need to be installed later, precise measurements of the installation location and determination of a suitable installation position are often required before designing and manufacturing the encoder mount. On-site assembly after production further complicates the installation and use of the encoder. Summary of the Invention

[0028] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0029] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or it can be indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," "right," "top," and "bottom" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

[0030] Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and not for limiting the scope of the invention. The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0031] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0032] Referring to Figures 1 and 2, in some embodiments, the adjustable encoder mounting mechanism according to the present invention includes a first clamp 110, a second clamp 120, a first shaft 210, a second shaft 220, and a third shaft 230 for connecting the encoder 500; the first shaft 210 is perpendicular to the second shaft 220, the second shaft 220 is perpendicular to the third shaft 230, and the third shaft 230 is perpendicular to the first shaft 210; the first clamp 110 is movably connected to the first shaft 210 and the second shaft 220 respectively, and the second clamp 120 is movably connected to the second shaft 220 and the third shaft 230 respectively.

[0033] The encoder 500 of this invention is fixed on an adjustable encoder mounting mechanism. By moving the first shaft 210, the second shaft 220, and the third shaft 230 relative to the first clamp 110 and the second clamp 120, the position of the encoder 500 in the three directions of the first shaft 210, the second shaft 220, and the third shaft 230 can be adjusted, as well as the concentricity of the encoder 500 with the rotating shaft can be adjusted. This achieves multi-degree-of-freedom adjustment of the encoder 500 mounting position, flexibly and conveniently adjusting the concentricity of the encoder 500 with the rotating shaft, while reducing the requirements for the encoder 500 mounting position.

[0034] Specifically, this invention includes a first axis 210, a second axis 220, and a third axis 230, each corresponding to one of the three coordinate directions in a coordinate system. For example, the first axis 210, the second axis 220, and the third axis 230 correspond to the X-axis, Y-axis, and Z-axis, respectively. The encoder 500 is mounted on the third axis 230. The third axis 230 and the second axis 220 are movable relative to the second clamp 120, and the second axis 220 and the first axis 210 are movable relative to the first clamp 110. This allows adjustment of the encoder 500's position in the X, Y, and Z directions, meaning its vertical, horizontal, and forward / backward positions are adjustable. Furthermore, the third axis 230 and the second axis 220 are rotatable relative to the second clamp 120, and the second axis 220 and the first axis 210 are rotatable relative to the first clamp 110, allowing for flexible adjustment of the encoder 500's mounting angle. Using the adjustable encoder 500 mounting mechanism of this invention, the requirements for the mounting position of the encoder 500 can be reduced, thereby facilitating the adjustment of the concentricity between the encoder 500 and the rotating shaft. It is understood that the first shaft 210, the second shaft 220, and the third shaft 230 of this invention can be optical shafts.

[0035] It should be noted that in the conventional structure of encoder 500, coupling 600, and rotating shaft (client-side drive), coupling 600 and encoder 500 are respectively located on opposite sides of the mounting bracket. The encoder 500's connecting shaft passes through the mounting bracket and connects to coupling 600. The other end of coupling 600 is used to connect to the client-side drive, such as a motor's rotating shaft. The traditional installation method for encoder 500 and rotating shaft generally includes: using a base or other suitable location on the rotating shaft as the mounting position for encoder 500; fixing the encoder 500 mounting bracket with screws; and ensuring the precise positioning of the mounting bracket, specifically aligning the center height of the circular hole on the mounting bracket that positions the encoder 500 with the center height of the motor's rotating shaft. After that, tighten the screws to secure the mounting bracket; fit the stop of the front mounting flange of the encoder 500 into the positioning hole of the mounting bracket, and fix the encoder 500 to the mounting bracket with screws; move the flexible coupling 600 that was previously fitted onto the rotating shaft so that the holes at both ends of the coupling 600 fit onto the rotating shaft and the connecting shaft of the encoder 500 respectively, and then tighten the internal hex screws on the coupling 600 so that the connecting shaft of the encoder 500 is connected to the rotating shaft of the object being detected; slightly loosen the screws that fix the encoder 500 bracket, rotate the rotating shaft by hand, and at the same time move and adjust the position of the bracket until the encoder 500 rotates with the motor without shaking. At this point, the coaxiality adjustment is complete. Tighten the fixing screws to firmly fix the encoder 500 bracket to the base. In response to the problems in the traditional encoder 500 mounting structure mentioned above, such as the difficulty in adjusting the concentricity between the encoder 500 and the rotating shaft and the requirement for specific requirements in the mounting position of the encoder 500 mounting bracket, this application designs an adjustable encoder mounting mechanism to achieve multiple free and flexible adjustment of the encoder 500 mounting position and flexible adjustment of the concentricity between the encoder 500 and the rotating shaft.

[0036] In some embodiments, the encoder 500 mounting mechanism of this utility model includes a first base 310, which is connected to the end of a first shaft 210. Specifically, the first base 310 is fixed to the ground by base screws, and the lower end of the first shaft 210 is inserted into and fixed to the first base 310, so that the first shaft 210 is vertically positioned. Further, the first base 310 can be fixed to the first shaft 210 by clamping with screws. Referring to Figures 1 and 2, the first base 310 includes a first base plate 311 and a first fixing block 312. The first base plate 311 is fixed to the ground by base screws. The first fixing block 312 is disposed on the upper side of the first base plate 311. The first fixing block 312 is provided with a first fixing hole 313. The hole wall of the first fixing hole 313 is provided with a first fixing groove 314. The two side walls of the first fixing groove 314 are each provided with a first hole 315. When the lower end of the first shaft 210 is inserted into the first fixing hole 313, the first fixing screw is inserted into the first hole 315 on the two side walls and tightened by fixing nuts, so that the hole wall of the first fixing hole 313 abuts against the first shaft 210, thereby fixing the first shaft 210 on the first base 310 and setting it vertically.

[0037] In some embodiments, the encoder 500 mounting mechanism of this invention includes a second base 320, which is connected to the end of a third shaft 230. Specifically, one end of the third shaft 230 is inserted into and fixed to the second base 320. Further, the second base 320 can be used to fix the third shaft 230 by clamping with screws. Referring to Figures 1 and 2, the second base 320 includes a second base plate 321 and a second fixing block 322. The second base plate 321 is fixed to the mounting plate 400 by screws. The second fixing block 322 is disposed on one side of the second base plate 321. The second fixing block 322 is provided with a second fixing hole, and a second fixing groove is provided on the wall of the second fixing hole. Second holes are provided on both side walls of the second fixing groove. When one end of the third shaft 230 is inserted into the second fixing hole, the second fixing screw is inserted into the second holes on the two side walls and tightened with a fixing nut, so that the wall of the second fixing hole abuts against the third shaft 230, thereby fixing the third shaft 230 to the second base 320. It is understood that the first base 310 and the second base 320 have the same structure. Furthermore, the first base 310 and the second base 320 can use existing national standard parts, making the purchasing channels diverse and allowing for direct purchase and use without secondary processing, effectively saving production and usage costs.

[0038] In some embodiments, the encoder 500 mounting plate 400 of this invention is connected to the second base 320. Specifically, the mounting plate 400 is disposed on the side of the second base 320 facing away from the third shaft 230, and the second base plate 321 of the second base 320 is fixedly connected to the mounting plate 400 by base screws. Further, the mounting plate 400 is provided with mounting holes 410 for connecting the encoder 500, and the mounting holes 410 are disposed on the side of the second base 320. Referring to Figures 1 and 2, the length of the mounting plate 400 is greater than the length of the second base plate 321. The second base plate 321 is fixed to one side of the mounting plate 400, while the other side of the mounting plate 400 is provided with mounting holes 410. Mounting holes 410 are also provided on the mounting plate 400 around the mounting holes 410. The encoder 500's connecting shaft protrudes through the mounting holes 410 and onto the other side of the mounting plate 400. After the mounting surface of the encoder 500 is flush with the side of the mounting plate 400, mounting screws are passed through the security holes and tightened to fix the encoder 500 to the mounting plate 400. Then, the coupling 600 is installed on the connecting shaft of the encoder 500. It should be noted that the encoder 500 is located on the side of the mounting plate 400 facing the third shaft 230. Furthermore, the coupling 600 of this utility model is a flexible coupling 600, and the flexible encoder 500 is an open type. By fitting the flexible coupling 600 onto the shaft head of the encoder 500 and tightening the connecting screws on the flexible encoder 500, the flexible coupling 600 can be clamped onto the shaft head of the encoder 500.

[0039] In some embodiments, the first clamp 110 is provided with two mutually perpendicular first connecting holes 111, and the first shaft 210 and the second shaft 220 are respectively movably inserted into the two first connecting holes 111, thereby achieving the first shaft 210 being perpendicular to the second shaft 220 through a simple structure.

[0040] In some embodiments, the second clamp 120 is provided with two mutually perpendicular second connecting holes 121, and the second shaft 220 and the third shaft 230 are respectively movably inserted into the two second connecting holes 121, thereby achieving the second shaft 220 being perpendicular to the third shaft 230 through a simple structure.

[0041] In some embodiments, the encoder 500 mounting mechanism of the present invention includes a plurality of adjusting screws for adjusting the contact positions of the first shaft 210 and the first clamp 110, the second shaft 220 and the first clamp 110, the second shaft 220 and the second clamp 120, and the third shaft 230 and the second clamp 120, respectively.

[0042] This explanation uses the following examples: the first shaft 210 is vertically positioned and extends in the up-down direction; the second shaft 220 is horizontally positioned and extends in the left-right direction; and the third shaft 230 is horizontally positioned and extends in the front-back direction. Specifically, the lower end of the first shaft 210 is connected to the first base 310, the upper side of the first shaft 210 passes through a first connecting hole 111 of the first clamp 110, the left side of the second shaft 220 passes through another first connecting hole 111 of the first clamp 110, the right side of the second shaft 220 passes through a second connecting hole 121 of the second clamp 120, the rear end of the third shaft 230 passes through another second connecting hole 121 of the second clamp 120, and the front end of the third shaft 230 is connected to the second base 320, thereby realizing the adjustment of the encoder 500's up-down, left-right, and front-back positions.

[0043] It is understandable that the first fixture 110 and the second fixture 120 have the same structure. Furthermore, the first fixture 110 and the second fixture 120 can adopt existing national standard parts, which makes the purchase channels diverse and can be purchased and used directly without secondary processing, effectively saving production and manufacturing costs and usage costs.

[0044] Referring to Figures 1 and 2, each of the two first connecting holes 111 has a first adjusting groove on its sidewall. Each of the two sidewalls of the first adjusting groove has a first threaded hole. When the first shaft 210 or the second shaft 220 is inserted into the first connecting hole 111, the adjusting screw is inserted into the two corresponding first threaded holes of the first connecting hole 111 and tightened, thus fixing the first clamp 110 onto the first shaft 210 or the second shaft 220. Furthermore, loosening the adjusting screw allows the first clamp 110 to move up and down relative to the first shaft 210, or to move left and right relative to the second shaft 220.

[0045] Referring to Figures 1 and 2, each of the two second connecting holes 121 has a second adjusting groove 122 on its sidewall. The two sidewalls of the second adjusting groove 122 each have a second threaded hole 123. When the second shaft 220 or the third shaft 230 is inserted into the second connecting hole 121, the adjusting screw is inserted into the two corresponding second threaded holes 123 of the second connecting hole 121 and tightened, thus fixing the second clamp 120 onto the second shaft 220 or the third shaft 230. Furthermore, loosening the adjusting screw allows the second clamp 120 to move left or right relative to the second shaft 220, or to move back and forth relative to the third shaft 230.

[0046] Here, a specific embodiment is used for illustration. When installing the encoder 500 and the rotating shaft using the adjustable encoder mounting mechanism of this embodiment, first select a suitable position around the rotating shaft device to be mounted, fix the first base 310 in the aforementioned suitable position, and then install the first shaft 210, the first clamp 110, the second shaft 220, the second clamp 120, the third shaft 230, the second base 320, the mounting plate 400, the encoder 500, and the coupling 600. Since the first shaft 210, the second shaft 220, and the third shaft 230 all have a certain length, during the installation process, the contact position of the first clamp 110 with the first shaft 210 and the second shaft 220, as well as the contact position of the second clamp 120 with the second shaft 220 and the third shaft 230, can be adjusted according to the position of the rotating shaft. This allows the axial center position of the encoder 500 and the coupling 600 to match the axial center position of the rotating shaft, and also adjusts the concentricity of the rotating shaft and the encoder 500.

[0047] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
