Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of encoders, in particular to a split type encoder capable of adapting to various motor installation sizes, and specifically to a split type encoder capable of realizing various installation modes and a rotating device provided with the split type encoder. BACKGROUND

[0002] An encoder is a sensor that can deliver angle, speed and number of turns in real time. It is generally installed on the rotating shaft of a servo motor or an automatic device to convert the speed and angular displacement of the rotating shaft into an electrical signal for closed-loop feedback. With the popularization of industrial intelligence, various automatic devices have increasingly high requirements for the stability, precision and other performance of servo control systems, and the requirements for the installation size, stability and service life of encoders as important feedback units in servo control systems are also increasing.

[0003] At present, mainstream encoders can be generally divided into integrated encoders and split type encoders in terms of structural form. The integrated encoder has contact type bearings inside and has high installation stability but a relatively large size. The split type encoder has a non-contact form between the magnet shaft and the encoder body, and the overall size of the split type encoder is small. Since the split type encoder adopts a non-contact form, its service life is high, but the split type encoder needs to adapt to the installation sizes of different motors, so it is generally matched with multiple specifications of installation bases, which causes problems such as complicated replacement and high installation and use cost in specific applications.

[0004] In order to solve the above problems, the Chinese utility model patent CN202122427173.X discloses a split type encoder adapted to different motor shaft lengths, which includes a double-sided installation body, a magnet holder assembly, an integrated circuit board assembly, a metal shield, a special-shaped anti-disassembly bolt and the like. The magnet holder assembly includes a magnet holder and a magnet, and the integrated circuit board assembly includes an integrated circuit board, a magnetic chip and a quick plug terminal plug. The double-sided installation body includes double-sided installation stations with the same structure and different side wall heights, and each installation station is provided with a positioning column for installing and accurately positioning the integrated circuit board and an internally threaded embedded part threadedly matched with the special-shaped anti-disassembly bolt. The special-shaped anti-disassembly bolt passes through the mounting holes of the metal shield and the integrated circuit board to fix them on the double-sided installation body. The double-sided installation body is fixed on the motor housing.

[0005] Although the scheme disclosed in the above patent document can match different shaft length specifications of the motor by changing the mounting station of the double-sided mounting body, the installation process is complicated and basically includes the following steps: 1. installing the magnet support assembly: fixing and installing the magnet support assembly (including the magnet support and the magnet) on the motor shaft; 2. positioning the integrated circuit board assembly: placing the integrated circuit board assembly (including the integrated circuit board, the magnetic chip and the quick plug terminal plug) above the magnet support assembly; 3. installing the metal shield: placing the metal shield on the integrated circuit board; 4. using a special anti-disassembly bolt: passing the special anti-disassembly bolt through the mounting hole on the metal shield and the integrated circuit board, and then fixing it on the double-sided mounting body; 5. using the body mounting bolt to fix the double-sided mounting body on the motor housing through the body mounting hole. Basically, the above steps are reversed to be the disassembly process of the encoder. After disassembly, the double-sided mounting body needs to be turned over, and then the encoder is installed in place according to the above installation steps. Therefore, the encoder structure disclosed in the above patent document is relatively complex, and it is not convenient to change and disassemble.

[0006] Therefore, the current split type encoder is still not well solved the problem of complicated replacement and high installation and use cost, and it is still necessary to propose a new technical scheme to solve the above problems. Utility model content

[0033] Embodiment one

[0034] The embodiment provides a split encoder capable of realizing various installation modes. Figure 1 The split encoder mainly comprises a body assembly and a magnet assembly. The body assembly comprises a mounting seat 3, a circuit board 2 and a fastening screw 1. The circuit board 2 is mounted in the mounting seat 3. The mounting seat 3 is provided with mounting protrusions 31 for positioning the circuit board 2 in the radial and axial directions. Meanwhile, the mounting positions are provided with different heights to meet the requirements of different installation sizes. Finally, the circuit board 2 and the mounting seat 3 are mounted on a rotating device through the fastening screw 1.

[0035] Specifically, continuing to refer to Figure 1 , the upper surface of the mounting seat 3 is provided with at least two mounting protrusions 31. Each mounting protrusion 31 is formed with at least two horizontal mounting surfaces 311 with different heights. The horizontal mounting surfaces 311 with the same height of the two mounting protrusions 31 form mounting stations of the circuit board 2. The horizontal mounting surfaces 311 are provided with vertical fastening holes 312. The circuit board 2 is provided with two mounting holes 21 in opposite positions. The mounting holes 21 are in communication with the vertical fastening holes 312 to form mounting channels for mounting the fastening screw 1. The fastening screw 1 is matched with the threaded holes on the rotating device.

[0036] The number of the horizontal mounting surfaces 311 with different heights provided on the mounting protrusions 31 in the application is the number of various installation modes of the split encoder provided by the application. Therefore, the application realizes the split encoder structure meeting at least two installation size requirements without replacing the base by providing the mounting protrusions 31 with multiple horizontal mounting surfaces with different heights on the mounting seat 3, which can effectively reduce the use cost of the split encoder.

[0037] In a preferred embodiment of the application, the upper surface of the mounting seat 3 is provided with two mounting protrusions 31 in opposite positions. Each mounting protrusion 31 is provided with two horizontal mounting surfaces with different heights. The first horizontal mounting surface on one mounting protrusion 31 has the same height as the first horizontal mounting surface on the other mounting protrusion 31, thereby forming a first mounting station of the circuit board 2. The second horizontal mounting surface on one mounting protrusion 31 has the same height as the second horizontal mounting surface on the other mounting protrusion 31, thereby forming a second mounting station of the circuit board 2, as shown in Figure 2 Each horizontal mounting surface is provided with a vertical fastening hole 312. The circuit board 2 is provided with two mounting holes 21 in opposite positions. The fastening screw 1 is sequentially penetrated through the mounting holes 21 and the vertical fastening holes 312 and then matched and connected with the threaded holes provided on the rotating device.

[0038] In other embodiments, the upper surface of the mounting seat 3 can be provided with three, four or more mounting protrusions 31. All the mounting protrusions 31 are uniformly distributed along the outer edge of the mounting seat 3. Each mounting protrusion 31 is formed with multiple horizontal mounting surfaces with different heights.

[0039] In one preferred embodiment of the present application, a middle portion of the mounting base 3 is provided with a mounting base hole for mounting the magnet assembly. Referring to Figure 1 、 3 , the magnet assembly comprises a magnet 4, a magnet shaft 5 and a set screw 6. The magnet shaft 5 is provided with a connecting hole along an axial direction thereof. The connecting hole is formed with a receiving cavity for accommodating the magnet 4 near one end of the circuit board 2. The connecting hole is adapted to the rotating shaft 8 of the rotating device. The magnet shaft 5 is provided with one or more threaded holes for mounting the set screw 6 along a radial direction of a side wall thereof. In a specific installation, at least a portion of the magnet 4 is mounted in the receiving cavity inside the magnet shaft 5 and is fixed by adhesion.

[0040] In operation, the magnet assembly is adapted to the rotating shaft 8 of the rotating device through the connecting hole on the magnet shaft 5 and is fixed to the rotating shaft 8 through the set screw 6. The magnet assembly can rotate with the rotating shaft 8 of the rotating device. Like the conventional split type encoder, the circuit board 2 provided on the body assembly can sense the polarity of different magnetic poles on the magnet and convert the sensed rotating magnetic field signal into an electrical signal that can be used for an external intelligent control system. The electrical signal is transmitted to the external intelligent control system through an interface provided on the circuit board 2 to form a closed loop control.

[0041] In one preferred embodiment of the present application, referring to Figure 1 , the upper surface of the mounting base 3 is provided with a positioning column 32 near the mounting protrusion 31. The circuit board 2 is provided with a positioning hole 22 adapted to the positioning column 32. The positioning column 32 can assist in installation and positioning. The circuit board 2 can be installed and positioned in the axial and radial directions through the positioning column 32 and the fastening screw 1.

[0042] In one preferred embodiment of the present application, referring to Figure 1 , the upper surface of the mounting base 3 is provided with two mounting clamping protrusions 33 in addition to the two mounting protrusions 31. The mounting protrusions 31 and the mounting clamping protrusions 33 are alternately arranged along the outer edge of the mounting base 3. Specifically, each mounting clamping protrusion 33 is formed with a first clamping surface 331, a second clamping surface 332 and a limiting protrusion 333. The first clamping surface 331 has the same height as the first horizontal mounting surface on the two mounting protrusions 31. The second clamping surface 332 has the same height as the second horizontal mounting surface on the two mounting protrusions 31. The limiting protrusion 333 is a protruding structure adjacent to the second clamping surface 332. The top of the limiting protrusion 333 is higher than the second clamping surface 332.

[0043] In addition, the outer edge of the circuit board 2 is provided with two limiting grooves 23 and two accommodating grooves 24. Referring to Figure 2When the circuit board 2 is installed on the first horizontal installation surface of the two installation protrusions 31, the two installation lugs 33 are respectively installed in the two limiting grooves 23, and the edges of the circuit board 2 are installed on the first clamping surfaces 331 of the installation lugs 33, and the portions of the two installation protrusions 31 forming the second horizontal installation surface are respectively accommodated in the two accommodating grooves 24. When the circuit board 2 is installed on the second horizontal installation surface of the two installation protrusions 31, the limiting lugs 333 of the two installation lugs 33 are respectively installed in the two limiting grooves 23, and the edges of the circuit board 2 are installed on the second clamping surfaces 332 of the installation lugs 33. In the present application, the installation lugs 33 can cooperate with the installation protrusions 31 to achieve installation and positioning of the circuit board 2, and the stability of the installation of the circuit board 2 can be improved.

[0044] Therefore, the split encoder provided by the present application can realize multiple installation modes. The installation protrusions 31 are arranged on the mounting seat 3, and multiple horizontal installation surfaces with different heights are arranged on each installation protrusion 31, so that the horizontal installation surfaces with the same height on each installation protrusion 31 form an installation station of the circuit board 2, thereby forming a mounting seat 3 with multiple installation heights. In this way, the split encoder can meet at least two installation size requirements without replacing the base, and the use cost of the split encoder can be effectively reduced. In addition, the split encoder provided by the present application adopts a split design, has small installation size, can save installation space, and the body assembly and the magnet assembly adopt a non-contact form, so that the service life of the encoder can be improved.

[0045] Referring to Figure 2 When the split encoder provided by the present application needs to be replaced or installed on a rotating device with different sizes, it is not necessary to replace parts. The circuit board 2 is only separated from the mounting seat 3, and then the circuit board 2 is rotated and fixed with the mounting seat 3 again to change into the second installation mode. It can be seen that the split encoder provided by the present application has simple replacement operation, and the efficiency of installing and replacing the encoder can be improved.

[0046] Embodiment Two

[0047] The present embodiment provides a rotating device provided with the split encoder capable of realizing multiple installation modes provided by the first embodiment.

[0048] The rotating device provided by the present embodiment comprises a rotating mounting seat 3 and a rotating shaft 8 arranged in the rotating mounting seat 3. The rotating mounting seat 3 is provided with a fastening screw hole 7 corresponding to and matched with the fastening screw 1. The rotating shaft 8 is provided with one or more screw holes on the side wall thereof extending out of the rotating mounting seat 3 and along the radial direction thereof, and the screw holes are corresponding to and matched with the fastening screw 6.

[0049] Referring to Figure 3As can be seen from the sectional view, the magnet shaft 5 of the split encoder in the application is provided with a through hole opened along the axial direction thereof, when installed, the axial hole on the magnet shaft 5 is sleeved into the rotating shaft 8 of the rotating device, in addition, the rotating shaft 8 of the rotating device is provided with screw holes distributed along the radial direction thereof, the set screw 6 is in contact with the rotating shaft 8 of the rotating device through the screw holes and is fastened.

[0050] The installation and fixing mode of the split encoder provided by the application can be briefly described as follows: referring to Figure 4 , when the split encoder is fixed on the measured device (such as the rotating device in the application), the first step is to pass the magnet assembly of the encoder into the measured rotating shaft 8 through the axial hole on the magnet shaft 5, the second step is to sequentially screw and tighten the set screw 6 to relatively fix the magnet assembly and the rotating shaft 8, the third step is to place the encoder body assembly on the installation surface of the rotating mounting seat 3 of the rotating device, so that the bottom end surface of the mounting seat 3 is attached to the installation surface, and the threaded hole for installing the fastening screw 1 opened on the body assembly is aligned with the fastening threaded hole 7 opened on the mounting seat 3, the fourth step is to sequentially pass the fastening screw 1 through the threaded holes on the circuit board 2 and the mounting seat 3 and screw it into the fastening threaded hole 7 of the rotating device, so that the body assembly is relatively fixed with the body of the rotating device.

[0051] Therefore, when the split encoder provided by the application changes the installation mode, only the fastening screw needs to be removed, so that the structure separation between the circuit board and the mounting seat and the structure separation between the mounting seat and the rotating device can be realized, after the fastening screw is removed, without replacing the parts, only the circuit board needs to be rotated to the position and then fixed with the mounting seat through the fastening screw, so that the change of the installation mode can be realized, therefore, the split encoder provided by the application has simple replacement operation and can improve the efficiency of installing and replacing the encoder.
