Description

Technical Field

[0001] The utility model relates to the technical field of encoders, and in particular to an encoder jig. Background Art

[0002] Encoders are widely used in fields such as industrial control, mechanical manufacturing, and optics. They compile and convert signals or data and output them as signals that can be used for communication, transmission, and storage. When used in a spectrometer, an encoder can detect and provide feedback on the rotation angle of the grating, thereby improving the overall performance of the spectrometer.

[0003] In a specific usage scenario, the encoder's rotor is connected to the grating base's drive shaft, and the spectrometer's stator is bolted to the spectrometer's main body, allowing the rotor to stably rotate synchronously with the drive shaft. However, this fixing method makes it easy for disassembly and assembly to damage the encoder's structure. Furthermore, when fixed, stress concentrates at the connection between the stator and the spectrometer's main body, which can also easily cause structural damage. This affects the accuracy of the rotor's synchronous rotation with the drive shaft and reduces the encoder's detection accuracy. Utility Model Content

Furthermore, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0030] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present invention are not absolute but relative. These descriptions are applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0031] On the one hand, the present invention provides an encoder fixture, please refer to Figures 1 to 4An encoder jig provided in one embodiment of the present invention is used to connect an encoder 3 and a spectrometer body 4. The encoder 3 includes a connected body and a connecting portion 32. The connecting portion 32 is located on the outer periphery of the body. The encoder jig mainly includes a jig body 1 and a fastener 2. The jig body 1 includes a main body portion 11 and an extension portion 12 connected in a bent manner. The main body portion 11 is provided with a positioning hole 114. The main body portion 11 is sleeved on the outside of the main body 31 through the positioning hole 114. The connecting portion 32 is located between the main body portion 11 and the spectrometer body 4. The main body portion 11 can prevent the connecting portion 32 from escaping from the side where the main body portion 11 is located. The extension portion 12 is used for gripping. The fastener 2 is respectively connected to the main body portion 11 and the spectrometer body 4, and the main body portion 11 presses the connecting portion 32 against the spectrometer body 4 to connect the encoder 3 and the spectrometer body 4.

[0032] In the encoder jig of the present embodiment, during installation, the encoder 3 is moved to a position opposite the spectrometer body 4, the main body 11 is placed over the main body 31 of the encoder 3, and the main body 11 is connected to the spectrometer body 4 via the fastener 2. Since the connecting portion 32 is located between the main body 11 and the spectrometer body 4 and does not fall out from the side where the main body 11 is located, the main body 11 applies pressure to the connecting portion 32 under the action of the fastener 2, pressing the connecting portion 32 against the spectrometer body 4. Thus, through the cooperation of the jig body 1 and the fastener 2, the encoder 3 and the spectrometer body 4 are connected. During disassembly, the operations are performed in the reverse order. Using this encoder jig, the encoder 3 and the spectrometer body 4 can be quickly and easily assembled and disassembled. The disassembly process does not require direct operation on the encoder 3, reducing the possibility of damage to the encoder 3 structure due to improper assembly and disassembly. During the installation and removal of the jig body 1, the operator can adjust the main body 11 by holding the extension 12, further improving the convenience of operation. On the other hand, the main body 11 presses the connecting part 32 onto the spectrometer body 4, and the pressure is transmitted through the contact surface between the main body 11 and the connecting part 32 and the contact surface between the connecting part 32 and the spectrometer body 4. The evenly distributed pressure enables the connecting part 32 to be fixed on the spectrometer body 4 more stably and reliably, and can reduce structural damage caused by excessive local stress, thereby improving the accuracy of the synchronous rotation of the rotor 312 of the encoder 3 and the grating seat transmission shaft 42, and improving the detection accuracy of the encoder 3.

[0033] Furthermore, the positioning holes 114 of the fixture body 1 play a role in positioning and supporting the encoder 3 body, ensuring that the encoder 3 will not shake or tilt left and right, and further ensuring that the encoder 3 can be stably fixed on the spectrometer body 4.

[0034] In a specific embodiment, the fastener 2 includes a connected rod and a cap. The rod has threads, passes through the body 11, and is screwed to the spectrometer body 4. The cap is used to press the body 11 against the connecting portion 32. The screw connection method has the characteristics of reliable connection and quick and convenient disassembly.

[0035] In a specific embodiment, the main body 11 is provided with a positioning groove (not shown in the accompanying drawings) that cooperates with the connecting portion 32. When the connecting portion 32 is pressed against the spectrometer body 4, the connecting portion 32 is located within the positioning groove. On the one hand, the positioning groove facilitates rapid alignment during installation, improving installation accuracy and efficiency. On the other hand, the groove wall of the positioning groove can restrict the connecting portion 32, thereby limiting the displacement and relative rotation of the encoder 3 as a whole on the plane, ensuring that the encoder 3 can be stably and accurately fixed to the spectrometer body 4, thereby improving the detection accuracy of the encoder 3.

[0036] On the other hand, the present invention provides an encoder assembly, see Figure 2 The encoder assembly includes an encoder 3 and an encoder fixture of any one of the above embodiments. The encoder 3 includes a main body and a connecting portion 32 connected to each other. The connecting portion 32 is located on the outer peripheral side of the main body.

[0037] See also Figures 1 to 4 In an embodiment in which the main body 11 is sleeved on the outside of the body through the positioning hole 114, the main body 11 is provided with a first portion 111, a second portion 112 and a third portion 113 respectively connected to one end of the first portion 111 and one end of the second portion 112, which are spaced side by side. The positioning hole 114 is formed between the first portion 111, the second portion 112 and the third portion 113, and an opening 115 communicating with the positioning hole 114 is formed between the other end of the first portion 111 and the other end of the second portion 112.

[0038] During the specific installation process, the operator holds the extension portion 12, aligns the opening 115 with the main body 31 of the encoder 3, and pushes the main body 31 of the encoder 3 into or out of the positioning hole 114 along the direction of the opening 115. The first part 111, the second part 112, and the third part 113 work together to press the connecting portion 32 against the spectrometer body 4. This structural design facilitates the operation of the main body 31 of the encoder 3 entering and exiting the positioning hole 114, thereby improving installation efficiency. In this embodiment, the third part 113 is connected to the extension portion 12, and the extension portion 12 is connected to the third part 113. When the operator holds the extension portion 12, the holding force can be evenly distributed on the main body 11, thereby improving the stability of the overall structure.

[0039] It is conceivable that the fastener 2 can be connected to the spectrometer body 4 through part or all of the first part 111, the second part 112 and the second part 112. In this embodiment, the fastener 2 is connected to the spectrometer body 4 through the first part 111 and the second part 112 respectively.

[0040] In a further embodiment, two limiting grooves 3111 are provided on the outer peripheral wall of the main body 31, and the first portion 111 and the second portion 112 are respectively inserted into the two limiting grooves 3111 to prevent the fixture body 1 from detaching from the main body 31 toward the side away from the spectrometer body 4. On the one hand, the cooperation between the limiting grooves 3111, the first portion 111, and the second portion 112 greatly enhances the stability and reliability of the connection between the fixture body 1, the main body 31 of the encoder 3, and the spectrometer body 4. On the other hand, the two limiting grooves 3111, the first portion 111, and the second portion 112 respectively prevent the main body 31 of the encoder 3 from rotating on a plane, further improving detection accuracy.

[0041] In other embodiments, the main body 11 is annular in structure and needs to be moved axially in the positioning hole 114 to fit and separate the main body 11 and the main body of the encoder 3. In scenarios where the operating space is limited, the operation is inconvenient. In order to enhance the connection stability and reliability, additional limiting structures are required on the jig body 1 and the main body 31 of the encoder 3. The overall structure is relatively complex and not convenient for quick and easy disassembly and assembly.

[0042] See also Figure 1 and Figure 2 In a specific embodiment, two connecting portions 32 are provided, symmetrically arranged on either side of the main body 31, and are respectively pressed against the spectrometer body 4 by the first portion 111 and the second portion 112. Because the first portion 111 and the second portion 112 are spaced apart side by side, and the two connecting portions 32 are symmetrically arranged on either side of the main body 31, the two connecting portions 32 are respectively pressed by the first portion 111 and the second portion 112, providing a more uniform pressure effect. The two connecting portions 32 can also disperse the pressure, preventing pressure from being concentrated on a single connecting portion 32. Furthermore, even if one of the connecting portions 32 cannot be pressed, the connection remains effective, making the connection more reliable.

[0043] In a further embodiment, two groups of fasteners 2 are provided, one group of fasteners 2 being connected to the first portion 111 and the spectrometer body 4, respectively, and the other group of fasteners 2 being connected to the second portion 112 and the spectrometer body 4, respectively. Each group of fasteners 2 includes at least two fastening sub-components 21, and two connecting portions 32 are respectively provided between two adjacent fastening sub-components 21 of the two groups of fasteners 2. The connection between the fasteners 2, the first portion 111, the second portion 112, and the two connecting portions 32 can effectively prevent loosening of the connection and enhance the stability and reliability of the connection between the encoder assembly and the spectrometer body 4.

[0044] See also Figure 1 、 Figure 2 and Figure 4 On the other hand, the present invention provides a spectrometer, comprising a spectrometer body 4 and an encoder assembly according to any one of the above-described embodiments. The spectrometer body 4 comprises a housing 41 and a grating seat transmission shaft 42 that passes through the housing 41 and is partially exposed outside the housing 41. The main body 31 comprises a stator 311 and a rotor 312 rotatably disposed within the stator 311. The stator 311 is connected to the connecting portion 32. The main body 11 presses the connecting portion 32 against the housing 41. The rotor 312 is in transmission connection with the grating seat transmission shaft 42. The cooperation between the main body 11 and the connecting portion 32 secures the stator 311 to the housing 41, thereby ensuring the accuracy of the synchronous rotation between the rotor 312 and the transmission shaft and the detection accuracy of the spectrometer body 4.

[0045] See also Figure 3 and Figure 4 In a specific embodiment, a through-hole is formed on the housing 41, and a bearing seat 411 is provided in the through-hole. The grating seat transmission shaft 42 passes through the bearing seat 411 and is partially exposed outside the housing 41. The fastener 2 is connected to the bearing seat 411, and the connecting portion 32 is pressed against the bearing seat 411. The encoder assembly is tightly connected to the spectrometer body 4 through the cooperation among the fastener 2, the fixture body 1, the connecting portion 32 and the bearing seat 411. This connection method ensures that the stator 311 has a stable relative position with respect to the grating seat transmission shaft 42, ensuring the accuracy of the synchronous rotation between the rotor 312 and the transmission shaft. Moreover, since the bearing seat 411 is a component directly associated with the transmission shaft, its positional accuracy is relatively high. The fastener 2 is connected to the bearing seat 411, and the connecting portion 32 is pressed against the bearing seat 411. The high-precision positioning of the bearing seat 411 can be utilized to ensure the accuracy of the encoder 3 when measuring the rotation of the transmission shaft.
