Technical Field

[0001] The utility model belongs to the technical field of press-fitting devices, and specifically relates to a code disk press-fitting device. Background Art

[0002] In the field of motor processing technology, the code disk, as a digital encoder for measuring angular displacement, is widely used in various occasions that require precise measurement of the shaft rotation angle position due to its advantages such as strong resolution ability, high measurement accuracy, and reliable operation. The code disk is mainly divided into two types: the absolute encoder and the incremental encoder. The former can directly give the digital code corresponding to the angular position, and the latter calculates the angular displacement by performing addition and subtraction operations on the pulse increment generated by the rotating code disk through a calculation system;

[0003] During the press-fitting process of the code disk, it is necessary to fix the motor to be press-fitted, and each time the motor is fixed, it is necessary to manually calibrate the fixed position of the motor. The operation process is not only cumbersome but also consumes a lot of labor. Therefore, a code disk press-fitting device is proposed for the above problems. Summary of the Utility Model

The upper inner wall of the fixing frame is fixedly connected with a second fixing seat. The middle part of the lower end of the second fixing seat is fixedly connected with an electric cylinder in an inserted manner. The lower end of the electric cylinder is fixedly connected with a press-fitting structure.

[0007] Preferably, the clamping structure is located inside the operation cavity, and the press-fitting structure corresponds to the clamping structure in position.

[0008] Preferably, the clamping structure includes a bottom plate and four clamping blocks. Four adjustment grooves are arranged at equal distances in a circular array on the upper end of the bottom plate. First fixing rods are arranged on the lower sides of the four clamping blocks.

[0011] By adopting the above technical solution: The bottom plate is attached to the inner lower wall of the operation chamber, which can reduce the pressure on the connection between the bottom plate and the servo motor brought by the motor to be press-fitted.

[0012] Preferably, the guide frame is located above the bottom plate and fixedly connected to the inner surface of the operation chamber.

[0013] By adopting the above technical solution: The guide frame can guide the four clamping blocks, so that the four clamping blocks can move in a horizontal state.

[0016] Preferably, the press-fitting structure includes a fixing plate. A press-fitting cylinder is fixedly connected to the middle of the lower end of the fixing plate. Support plates are fixedly connected to the left and right sides of the lower end of the fixing plate respectively.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] The following gives specific embodiments.

[0037] Please refer to Figures 1-6 , the present invention provides a code disk pressing device, including a fixed frame 1. The lower inner wall of the fixed frame 1 is fixedly connected with a first fixed seat 2. The middle part of the upper end of the first fixed seat 2 is provided with an operation cavity 3. The lower inner wall of the operation cavity 3 is provided with a fixed groove 4. A servo motor 5 is fixedly connected inside the fixed groove 4. The output end of the servo motor 5 is fixedly connected with a clamping structure 6. The upper inner wall of the fixed frame 1 is fixedly connected with a second fixed seat 7. The middle part of the lower end of the second fixed seat 7 is inserted and fixedly connected with an electric cylinder 8. The lower end of the electric cylinder 8 is fixedly connected with a pressing structure 9. The clamping structure 6 is located inside the operation cavity 3, and the pressing structure 9 corresponds to the position of the clamping structure 6.

[0038] Further, as Figures 2-3 shown, the clamping structure 6 includes a base plate 61 and four clamping blocks 62. Four equally spaced annularly arrayed adjusting grooves 63 are opened at the upper end of the base plate 61. First fixed rods 64 are provided on the lower sides inside the four clamping blocks 62. Second fixed rods 65 are fixedly connected to the lower ends of the four clamping blocks 62. A guide frame 66 is slidably connected to the outer surfaces of the four first fixed rods 64. The base plate 61 is fixedly connected to the output end of the servo motor 5, and the lower end of the base plate 61 is in contact with the lower inner wall of the operation cavity 3. The guide frame 66 is located above the base plate 61 and is fixedly connected to the inner surface of the operation cavity 3. The four second fixed rods 65 are respectively located inside the four adjusting grooves 63 and are respectively slidably connected to the four adjusting grooves 63.

[0039] Through the above solution: When using the device for the press-fitting operation of the code disk, the motor to be press-fitted can be placed between the four clamping blocks 62 in the clamping structure 6. The four clamping blocks 62 can achieve synchronous positioning and clamping through the drive of the servo motor 5, so that after the motor to be press-fitted is clamped and fixed, there is no need for deliberate positioning operation.

[0040] Furthermore, as Figures 4-6 shown, the press-fitting structure 9 includes a fixing plate 91. A press-fitting cylinder 92 is fixedly connected to the middle of the lower end of the fixing plate 91. Support plates 93 are fixedly connected to the left and right sides of the lower end of the fixing plate 91 respectively. Activity holes 94 are opened in the middle of the lower sides of the outer surfaces of the two support plates 93. Guide rods 95 are inserted and movably connected to the inner surfaces of the two activity holes 94. Springs 96 are sleeved on the outer parts of the two guide rods 95. Limit plates 97 are fixedly connected to the mutually remote ends of the two guide rods 95. Clamping plates 98 are fixedly connected to the mutually close ends of the two guide rods 95. Positioning grooves 99 are opened in the lower parts of the inner surfaces of the two clamping plates 98. The fixing plate 91 is fixedly connected to the electric cylinder 8. The two springs 96 are respectively located between the two support plates 93 and the two clamping plates 98. The two clamping plates 98 are both located below the press-fitting cylinder 92.

[0041] Through the above solution: By providing two adjustable clamping plates 98 in the press-fitting structure 9, and at the same time, positioning grooves 99 for positioning the levelness of the code disk are opened on the inner surfaces of the two clamping plates 98, when the device performs the press-fitting operation of the code disk, it can be clamped and used for code disks of different models, and the code disk can maintain the required levelness when fixed, avoiding deviation in press-fitting.

[0042] Working principle: In the operation process of the device, through precise control of the operation of the servo motor 5, flexible operation of the clamping structure 6 is realized. Specifically, when the servo motor 5 is started to rotate forward, the bottom plate 61 is driven to rotate clockwise, which causes the four clamping blocks 62 to separate accordingly, creating enough space for the motor to be press-fitted. Subsequently, the prepared motor is accurately placed at the central position of the four separated clamping blocks 62. Next, the rotation direction of the servo motor 5 is changed to make the bottom plate 61 rotate counterclockwise, driving the four clamping blocks 62 to move synchronously towards the center and tightly clamp the motor. This process not only stabilizes the motor but also completes its positioning and calibration work, ensuring the accuracy of subsequent press-fitting operations.

[0043] Immediately afterwards, according to actual needs, a corresponding model of the code disk is selected and embedded between the two clamping plates 98. The horizontally designed positioning grooves 99 inside the two clamping plates 98 provide accurate levelness positioning for the code disk, ensuring that the code disk remains horizontal during the installation process and avoiding installation deviation.

[0044] Finally, start the electric cylinder 8, and use its downward pressure to push the pressing cylinder 92 to descend vertically, directly and effectively press the code disk onto the motor. The entire operation process is smooth and efficient, not only simplifying the complex steps of traditional pressing operations, but also greatly improving the flexibility and applicability of the device, enabling code disks of different models to be perfectly pressed and processed on this device.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
