Description

Technical Field

[0001] This utility model relates to the field of encoder technology, specifically to a rapid calibration auxiliary device for encoders. Background Technology

[0002] An encoder is a device that converts signals (such as mechanical motion) into electrical signals. It is widely used in various industrial and electronic systems. It can accurately measure and record physical quantities such as position, speed, and direction, and output this information in the form of digital or analog signals. An encoder typically contains a rotating part and a sensor. When the rotating part rotates, the sensor detects this change and converts it into a corresponding electrical signal. These signals can be read and processed by a microprocessor to control the movement of a machine or monitor the operating status of a system.

[0003] There are various types of encoders, including incremental and absolute encoders. Incremental encoders provide relative position information and generate a series of pulses with each rotation. By counting these pulses, the amount of rotation can be determined. Absolute encoders provide absolute position information and can remember their position even after power failure. Encoders have a wide range of applications, from simple counting applications to complex robot control, CNC machine tools, and automotive electronic systems. Their high precision and reliability make them an indispensable component of modern automation and precision control.

[0004] To ensure the accuracy of encoders, a rapid calibration auxiliary device is needed to calibrate them. This device typically involves placing the encoder body and driving it with an external motor. While the external motor rotates the encoder body's input shaft, it simultaneously detects the encoder body and adjusts parameters to correct any errors. While this method can calibrate the encoder body, the stability of its placement is crucial. If the device's positioning capability is poor, the external motor's drive can cause slight vibrations or displacements, leading to deviations in the calibration process. Therefore, this paper proposes a rapid calibration auxiliary device for encoders to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A rapid calibration auxiliary device for an encoder includes a base 1, a fixed seat 2 fixedly connected to the top rear end of the base 1, an encoder body 3 disposed above the fixed seat 2, positioning components 4 symmetrically disposed on the left and right sides of the fixed seat 2, a motor seat 5 fixedly connected to the top front end of the base 1, a calibration auxiliary component 6 disposed above the motor seat 5, an operation panel 7 disposed on one side of the base 1, the positioning component 4 includes an electric push rod 41, one side of the electric push rod 41 fixedly connected to the side wall of the fixed seat 2, the bottom of the electric push rod 41 fixedly connected to the top of the base 1, a transmission support rod 42 fixedly connected to the output end of the electric push rod 41, a positioning clamp 43 fixedly connected to the end of the transmission support rod 42 away from the electric push rod 41, a placement groove 21 is provided on the top of the fixed seat 2, and the bottom of the encoder body 3 is embedded in the placement groove 21.

[0027] As a further implementation of this solution, the positioning clamp 43 is vertically trapezoidal in shape. The side of the positioning clamp 43 closest to the encoder body 3 has an open structure. A reinforcing clamp 44 is provided inside the positioning clamp 43. The reinforcing clamp 44 is arc-shaped, and both its upper and lower ends are fixedly connected to the inner wall of the positioning clamp 43. Multiple rubber clamping blocks 45 are provided on the side of the reinforcing clamp 44 closest to the encoder body 3. The rubber clamping blocks 45 are trapezoidal in shape, and their wider sides are fixedly connected to the reinforcing clamping blocks 44. The side of the positioning clamp 43... An adjusting screw 46 runs through the wall and is threadedly connected to the positioning clamp 43. One end of the adjusting screw 46 is fixedly connected to an adjusting knob 47, and the other end of the adjusting screw 46 is fixedly connected to a reinforcing clamp 44. The positioning component 4 can perform double positioning of the encoder body 3 after it is placed in the placement groove 21. Double positioning can provide excellent positioning capability for the encoder body 3 and prevent the encoder body 3 from vibrating or displacing slightly due to the drive of the servo motor 61, thereby avoiding deviations in the detection and calibration of the encoder body 3.

[0028] As a further implementation of this solution, the calibration auxiliary component 6 includes a servo motor 61 fixedly connected to the top of the motor base 5. The output end of the servo motor 61 is fixedly connected to a drive shaft 62. An angle sensor 63 is sleeved on the outside of the drive shaft 62. A coupling 64 is provided on the side of the drive shaft 62 away from the servo motor 61. The drive shaft 62 and the input shaft of the encoder body 3 are positioned correspondingly. The end of the drive shaft 62 away from the servo motor 61 is connected to the adjacent end of the coupling 64. The end of the input shaft of the encoder body 3 is connected to the adjacent end of the coupling 64. The calibration auxiliary component 6 can perform detection and calibration on the encoder body 3.

[0029] Workflow: First, power on the operation panel 7 and electrically connect all electrical appliances to it. During calibration, first place the encoder body 3 in the placement groove 21 on top of the mounting base 2. The positioning component 4 can double-position the encoder body 3 after it is placed in the placement groove 21. Control the electric push rod 41 to retract via the operation panel 7. The retraction of the electric push rod 41 will drive the positioning clamp 43 to move towards the encoder body 3 and contact the side of the encoder body 3 through the transmission support rod 42. The contact between the positioning clamp 43 and the side of the encoder body 3 provides four-point clamping, so that the encoder body 3 is in the placement groove 21. The encoder exhibits good stability in the first position. Then, by adjusting knob 47, the adjusting screw 46 rotates on the positioning clamp 43. The rotating adjusting screw 46 moves the reinforcing clamp 44 towards the encoder body 3 until the rubber clamp 45 contacts the side of the encoder body 3. At this point, the contact points between the positioning clamp 43 and the side of the encoder body 3, plus the contact points between the rubber clamp 45 and the side of the encoder body 3, provide multiple clamping points, further improving the stability of the encoder body 3 in the placement groove 21. Furthermore, the rubber clamp 45 can buffer the clamping force due to its rubber properties, preventing damage to the encoder due to excessive clamping force. Damage to the encoder body 3 can be mitigated by the dual positioning of the positioning clamp 43 and the rubber clamp 45, which provides excellent positioning capability and prevents slight vibration or displacement of the encoder body 3 caused by the servo motor 61. This avoids deviations in the detection and calibration of the encoder body 3. After positioning, the input shaft end of the encoder body 3 is connected to the adjacent end of the coupling 64 in the calibration auxiliary component 6, and the end of the drive shaft 62 away from the servo motor 61 is connected to the adjacent end of the coupling 64. The servo motor 61 is controlled by the operation panel 7 to drive the drive shaft 62 to rotate at a preset speed. The drive shaft 62 is connected to the coupling 64. Simultaneously, the input shaft of the encoder rotates. The angle sensor 63 monitors the rotation angle of the drive shaft 62 in real time and transmits the data to the operation panel 7. The operation panel 7 processes and analyzes the data to determine whether the angle detection result of the encoder body 3 is qualified. If the detection result is qualified, the device automatically stops running, displays the detection result on the operation panel 7, and stores the detection data and historical records. If the detection result is unqualified, the device automatically stops running, displays the detection result on the operation panel 7, and personnel can then adjust the parameters of the encoder body 3 for calibration and continue testing with this device until the calibration is qualified.
