Description

Technical Field

[0001] The utility model relates to the technical field of encoder installation structures, in particular to a simple encoder installation and connection device. Background Art

[0002] In many old industrial fields, due to the design at that time, automatic control is generally not necessarily available, or the control accuracy is not high. With the development of intelligent manufacturing, unmanned and fully automated, encoders are often added to old motors or old rotating mechanical equipment to improve positioning or control accuracy or unmanned operation. However, in the original simple electromechanical control system, the output shaft of the old rotating electromechanical equipment was not extended (because the output shaft does not need to be installed with other equipment, and the outermost end of the output shaft is flush with the end face of the protective cover), and there are generally three types of encoders on the market (sleeve type: the encoder needs to be inserted into the rotating shaft; hanging flange connection type; base installation). Sometimes, in order to prevent the axial movement of the mechanical or motor shaft, an elastic (soft) coupling needs to be added between the output shaft of the rotating electromechanical equipment and the encoder. These connection methods require the old rotating electromechanical equipment to have an extended output shaft, but the rotating shaft of the old equipment did not have this condition in the past. Of course, the old rotating output shaft can also be updated by manufacturing a new extended shaft for installing the encoder to replace the old short shaft, or by modifying the old shaft and adding a dummy shaft to the electromechanical output shaft, but both methods or means have the problem of high cost and troublesome handling. Utility Model Content

[0003] The purpose of the utility model is to provide a simple encoder installation and connection device to solve at least one of the above problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A simple encoder installation and connection device comprises a mounting bracket, a fastening screw, a universal nut, a connecting pin and a flexible connector, wherein the lower end of the mounting bracket is fixedly mounted on a mounting seat, the upper end of the mounting bracket is provided with a protective cover, an encoder mounting position is provided on a vertical plate of the mounting bracket, the encoder mounting position comprises a middle through hole and a plurality of second connecting holes corresponding to the first connecting hole on the encoder flange, the second connecting holes are located around the middle through hole, the output shaft of the encoder passes through the middle through hole and is fixedly connected to the mounting hole at one end of the flexible connector, the universal nut is welded to the rotating output shaft of the motor or the reduction box, one end of the connecting pin is threadedly connected to the universal nut, and the other end of the connecting pin is fixedly connected to the mounting hole at the other end of the flexible connector.

[0006] This technical solution solves the problem of how to add an encoder to an old rotating machine or motor without an extra extended output shaft by installing a bracket, fastening screws, universal nuts, connecting pins and flexible connectors. This patent not only has low manufacturing and modification processing costs, but also has strong versatility, is easy to implement, and is very convenient to install or construct. By adding a connecting pin and a universal nut welded to the rotating output shaft of the motor or reducer, the function of extending the output shaft can be achieved on the output shaft of the old equipment. The connecting pin is also suitable for installing a sleeve encoder, and when equipped with a mounting bracket, it can also be used for base-type flange-mounted or suspended flange-mounted encoders. This solution can add an encoder to the output shaft of an old motor or old rotating machine (such as a reducer, etc.), and can be used in the field of installing a sleeve or flange-face encoder on a rotating shaft. This technical solution is simple, low-cost and highly practical. This technical solution, by adding a connecting pin, the connecting pin is a cylinder with unequal or equal diameters at both ends, one end with an external thread, the diameter or thread matches the inner diameter of the universal nut welded on the output shaft of the old rotating equipment, and the other end is consistent with the inner diameter of the mounting hole of the commercially available flexible connector (which absorbs axial movement and the difference in centering accuracy between the encoder and the output shaft of the rotating machinery, and can extend the service life of the encoder). That is, a universal nut plus a connecting pin can solve the problem of no extension of the output shaft of the old equipment (most of the original designs of old equipment did not consider adding encoders, so their output shafts are basically flush with the external cover). This patent solves the problems of encoder (flange type) installation and waterproof and dustproof protection by installing universal nuts, connecting pins and protective and fixed brackets. The bracket is simple and practical. Adding a flexible connector between the connecting pin and the mounting bracket solves the problems of encoder centering and preventing damage to the encoder caused by axial movement of electromechanical equipment.

[0007] Furthermore, in order to better protect the encoder, the protective cover is a U-shaped protective cover, and the encoder is located below the U-shaped protective cover.

[0008] Furthermore, in order to match the installation of the encoder, three second connection holes are provided at the encoder installation position, and the three second connection holes are arranged at equal intervals around the middle through hole.

[0009] Furthermore, in order to improve the stability of the mounting bracket, the mounting bracket includes a horizontal plate, an inclined support plate is provided between the horizontal plate and the vertical plate, and the horizontal plate is welded and fixed to the rotating machinery or motor mounting base.

[0010] Furthermore, in order to conveniently realize the fixed installation of the encoder output shaft and the flexible connector, the output shaft of the encoder and the mounting hole of the flexible connector are fixedly connected by a positioning pin.

[0011] Furthermore, in order to solve the problem that the output shaft of the old rotating electromechanical equipment has no extension, the output shaft is extended by welding a universal nut on the output shaft of the old rotating electromechanical equipment and adding a connecting pin.

[0012] The beneficial effects of the utility model are as follows: by means of mounting brackets, fastening screws, universal nuts, connecting pins and flexible connectors, the problem of how to simply and efficiently add encoders to old rotating machinery is solved, with low cost, strong versatility, easy implementation, and convenient installation or construction. The function of extending the output shaft of the old equipment is achieved by means of connecting pins and universal nuts welded on the rotating output shaft of the motor or the reducer. The connecting pin is also suitable for installing shaft sleeve encoders, and when equipped with a mounting bracket, it can also be suitable for base-mounted and suspended flange-mounted encoders. This solution can add encoders to the output shafts of old motors or old rotating machinery (such as reducers, etc.), and can be used in fields where shaft sleeve, base-mounted or suspended flange-mounted encoders need to be installed on rotating shafts. The technical solution is simple, low-cost and practical. This technical solution adds a connecting pin, which is a cylinder with two diameters, one end with an external thread, the diameter of which matches the inner diameter of the universal nut welded to the output shaft of the old rotating equipment, and the other end is consistent with the inner diameter of the mounting hole of the commercially available flexible connector (which absorbs axial movement and poor centering accuracy, and can extend the service life of the encoder). That is, a universal nut plus a connecting pin can solve the problem of extending the output shaft of the old equipment. The installation bracket solves the problems of encoder (flange type) installation and waterproof and dustproof protection. The bracket is simple and practical. Adding a flexible connector between the connecting pin and the mounting bracket solves the problems of encoder centering and preventing damage to the encoder caused by axial movement of electromechanical equipment.

[0020] like Figure 1-Figure 4 As shown, this embodiment provides a simple encoder installation and connection device, including a mounting bracket 1, a fastening screw 2, a universal nut 3, a connecting pin 4 and a flexible connector 5. The lower end of the mounting bracket 1 is fixedly mounted on the mounting seat 6, and the upper end of the mounting bracket 1 is provided with a protective cover 7.

The encoder mounting position includes a middle through hole 10 and a plurality of second connecting holes 13 corresponding to the first connecting hole 11 on the encoder flange 12. The second connecting holes 13 are located around the middle through hole 10. The output shaft of the encoder 9 passes through the middle through hole 10 and is fixedly connected to the mounting hole at one end of the flexible connector 5. The universal nut 3 is welded on the rotating output shaft 14 of the motor or the reducer. One end of the connecting pin 4 is threadedly connected to the universal nut 3, and the other end of the connecting pin 4 is fixedly connected to the mounting hole at the other end of the flexible connector 5.

[0021] This technical solution, through the installation bracket 1, fastening screws 2, universal nuts 3, connecting pins 4 and flexible connectors 5, solves the problem of how to add an encoder to an old rotating machine or motor without an extra extended output shaft. This patent not only has low manufacturing and modification processing costs, but also has strong versatility, is easy to implement, and is very convenient to install or construct. By adding a connecting pin 4 and a universal nut 3 welded to the rotating output shaft 14 of the motor or reducer, the function of extending the output shaft can be realized on the output shaft of the old equipment. The connecting pin 4 is also suitable for installing a sleeve encoder. At the same time, it is equipped with a mounting bracket 1 and can also be used for base-type flange-mounted or suspended flange-mounted encoders. This solution can add an encoder to the output shaft of an old motor or old rotating machine (such as a reducer, etc.), and can be used in the field of installing a sleeve or flange-face encoder on a rotating shaft. This technical solution is simple, low-cost and highly practical. This technical solution, by adding a connecting pin 4, the connecting pin 4 is a cylinder with unequal or equal diameters at both ends, one end with an external thread, the diameter or thread matches the inner diameter of the universal nut 3 welded on the output shaft of the old rotating equipment, and the other end is consistent with the inner diameter of the mounting hole of the commercially available flexible connector 5 (which absorbs axial movement and the difference in centering accuracy between the encoder and the output shaft of the rotating machinery, and can extend the service life of the encoder). That is, a universal nut 3 plus a connecting pin 4 can solve the problem of no extension of the output shaft of the old equipment (most of the original designs of the old equipment did not consider adding an encoder, so its output shaft is basically flush with the external cover). This patent solves the problems of encoder (flange type) installation and waterproof and dustproof protection by installing a universal nut 3, a connecting pin 4 and a protective and fixed bracket. The bracket is simple and practical. Adding a flexible connector 5 between the connecting pin 4 and the mounting bracket 1 solves the problems of encoder centering and preventing damage to the encoder caused by axial movement of electromechanical equipment.

[0022] Embodiment 2:

[0023] This embodiment is optimized based on the above-mentioned embodiment 1.

[0024] In order to better protect the encoder 9 , the protective cover 7 is a U-shaped protective cover 7 , and the encoder 9 is located below the U-shaped protective cover 7 .

[0025] Embodiment 3:

[0026] This embodiment is optimized based on the above-mentioned embodiment 1.

[0027] In order to match the installation of the encoder 9 , three second connection holes 13 are provided at the encoder installation position, and the three second connection holes 13 are arranged around the middle through hole 10 at equal intervals.

[0034] This technical solution can be installed on the output shaft of the motor rotor shaft or the gearbox without a cover plate and an extended shaft. With the requirements of intelligent manufacturing and full automation of the entire industry, many old motors and old reducer output shafts were originally designed to be straight with the end cover, and there is no setting for installing a sleeve encoder or an external mounting base and an extended shaft to receive the encoder. In order to install the encoder on the output shaft of the old equipment (motor or reducer economically and conveniently, this technical solution uses commercially available universal nuts and flexible connectors, equipped with newly designed connecting pins and mounting brackets designed according to the encoder installation size. It does not need to process and modify the output shaft of the old motor or old reducer to meet the electrical requirements for encoder installation. On the one hand, it is simple to make and easy to install. On the other hand, the price is very cheap. It is a very practical and economical encoder combined connector. At the same time, in terms of working characteristics, on the one hand, it can absorb axial movement, and on the other hand, the diameter of the mounting pin can be changed according to the radius of the output shaft of the different encoders.
