Description

Technical Field

[0001] The utility model relates to the field of clamping and coding of shaft products, in particular to a coding and feeding mechanism for automatic coding of motor shafts. Background Art

[0002] In the production of motor shafts, in order to facilitate the traceability of information such as production batches and manufacturers, after the motor shaft is processed, the motor shaft will be coded on the surface of the motor shaft by laser coding. The existing coding machine mainly includes a frame, a laser coding device, a code reading device, a multi-station rotary workbench and a controller. At least one station is arranged on the multi-station rotary workbench. Each station is provided with a universal fixture for clamping the workpiece to be coded. The laser coding device is located next to the coding station and is used to perform laser coding on the workpiece to be coded. The laser coding device, the code reading device and the motor are all electrically connected to the controller to receive the control instructions issued by the controller. When coding the workpiece, the motor drives the rotary workbench to rotate at a uniform speed and stops after rotating to the set angle. At this time, the controller issues an instruction to control the laser coding device to perform laser coding on the workpiece to be coded on the universal fixture at the coding station, and after the coding is completed, it issues an instruction to the motor to continue rotating, and in this way, the motor shaft coding and feeding are realized.

[0003] The existing coding devices include packaging box coding, bullet coding, and CD coding. The fixtures used for each coding are adapted to the corresponding product shape. There is a lack of special fixtures for coding motor shafts. Therefore, there is an urgent need for an automatic coding feeding mechanism that can position the motor shaft and is easy to pick up, install, and disassemble. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a coding and feeding mechanism for automatic coding of motor shafts, so as to solve the problem that the workpiece clamping fixture in the feeding mechanism of the existing automatic code scanning device is not suitable for the motor shaft.

In this way, when the motor shaft needs to be coded, first place the motor shaft in the motor shaft clamping groove of the U-shaped block, and then push the motor shaft so that its shaft shoulder is in close contact with the motor shaft shoulder fitting surface of the U-shaped block, and the end is clamped in the shaft end positioning hole on the positioning plate, and the shaft end positioning hole matches the end of the motor shaft, so as to avoid the rolling of the multi-station turntable during rotation and affect the coding position. After the motor shaft is fixed, start the drive motor, the multi-station turntable rotates, and the corresponding motor shaft rotates to the laser coding device, and the laser coding device performs coding. After the coding is completed, you only need to pull the motor shaft in the direction of the center of the multi-station turntable to remove the coded motor shaft. This structure can effectively position the motor shaft. When the motor shaft is installed, there is no obstruction and it is easy to install. When removing the motor shaft, you only need to pull it, which can effectively improve efficiency.

[0007] Furthermore, the angles between every two adjacent motor shaft positioning clamps are equal. In this way, the motor shaft positioning frame angles are evenly spaced, which facilitates the controller to set the rotation angle of the multi-station turntable, ensuring that after each rotation of a certain angle, the adjacent motor shaft positioning clamps are rotated to the coding station.

In this way, the multi-station turntable and the U-shaped block are fixed by the positioning pins, which is convenient for installation and disassembly, so that the corresponding U-shaped block can be replaced for different types of motor shafts.

[0009] Further, the motor shaft positioning clamp is made of plastic or rubber. In this way, the hardness of plastic and rubber is small, and after the motor shaft positioning clamp is made of plastic or rubber, scratches are not easy to appear when the motor shaft is placed.

[0010] Furthermore, the motor shaft clamping slot is arc-shaped or V-shaped, and the slot is tilted outwards and horn-shaped. In this way, the slot at the upper end of the motor shaft clamping slot is larger, thereby facilitating the placement of the motor shaft and being able to accommodate the placement of multiple motor shafts with different diameters.

[0011] Furthermore, a keyway connected to the shaft end positioning hole is provided. In this way, after the keyway is provided, it can cooperate with the spline at the end of the motor shaft, thereby determining the placement orientation of the motor shaft after placement, ensuring that the laser coding position of each motor shaft is at the set position.

[0017] In this embodiment, the motor shaft to be coded has a shoulder in the middle and a spline at one end. Figure 1-Figure 3As shown, the coding and feeding mechanism for automatic coding of motor shafts in this embodiment includes a multi-station turntable 1 whose lower end is fixedly connected to the output shaft of the driving motor, and a plurality of motor shaft positioning clamps 2 are detachably mounted on the multi-station turntable 1, and the motor shaft positioning clamps 2 are radially distributed with the center of the multi-station turntable 1, and each motor shaft positioning clamp 2 includes a U-shaped clamping block 21, and a motor shaft clamping through groove 22 is formed in the middle of the U-shaped clamping block 21; a positioning plate 23 is fixed to one end of the U-shaped clamping block 21 close to the outer edge of the multi-station turntable 1, and a shaft end positioning hole 24 matching the end of the motor shaft to be coded is provided on the positioning plate 23, and the end surface of the U-shaped clamping block 21 close to the center of the multi-station turntable 1 forms a motor shaft shoulder fitting surface 26. Using the coding feeding mechanism in this embodiment, when the motor shaft needs to be coded, the motor shaft is first placed in the motor shaft clamping groove 22 of the U-shaped block 21, and then the motor shaft is pushed so that its shaft shoulder is in close contact with the motor shaft shoulder fitting surface 26 of the U-shaped block 21, and the end is clamped in the shaft end positioning hole 24 on the positioning plate 23, and the shaft end positioning hole 24 cooperates with the motor shaft end, so as to avoid the multi-station turntable 1 from rolling during the rotation process, affecting the coding position. After the motor shaft is fixed, the drive motor is started, the multi-station turntable 1 rotates, and the corresponding motor shaft rotates to the laser coding device, and the laser coding device is used for coding. After the coding is completed, the motor shaft only needs to be pulled in the center direction of the multi-station turntable 1 to remove the coded motor shaft.

When removing the motor shaft, it only needs to be pulled, which can effectively improve efficiency.

[0018] In this embodiment, the outer end of each motor shaft positioning clamp 2 (the end close to the outer edge of the multi-station turntable 1) is extended out of the multi-station turntable 1, and the distance from the inner end of each motor shaft positioning clamp 2 to the center of the multi-station turntable 1 is equal. This arrangement ensures that the motor shaft positioning clamp 2 longer than the radius of the multi-station turntable 1 can also be assembled on the multi-station turntable 1, so as to adapt to the clamping and positioning of motor shafts of various lengths.

[0019] Furthermore, the angle between each two adjacent motor shaft positioning clamps 2 is equal, which is 60°. In this way, the motor shaft positioning frame angles are evenly spaced, which facilitates the controller to set the rotation angle of the multi-station turntable 1, ensuring that after each rotation of a certain angle, the adjacent motor shaft positioning clamps 2 are rotated to the coding station.

[0020] Furthermore, a plurality of mounting holes 11 for assembling the motor shaft positioning clamps 2 are provided on the multi-station turntable 1, and a plurality of positioning pins are provided at intervals along the length direction of each U-shaped block 21 on the lower end surface of each U-shaped block 21, and the U-shaped block 21 is fixed by the positioning pins and the mounting holes 11. In this way, the multi-station turntable 1 and the U-shaped block 21 are fixed by the positioning pins, which is convenient for installation and disassembly, so that the corresponding U-shaped block 21 can be replaced for different types of motor shafts.

[0021] Further, the motor shaft positioning clamp 2 is made of plastic or rubber. In this way, the hardness of plastic and rubber is small, and after the motor shaft positioning clamp 2 is made of plastic or rubber, scratches are not easy to appear when the motor shaft is placed.

[0022] Furthermore, the motor shaft clamping slot 22 is arc-shaped or V-shaped, and the slot is tilted outwards, forming a trumpet shape. In this way, the slot at the upper end of the motor shaft clamping slot 22 is larger, thereby facilitating the placement of the motor shaft and being able to accommodate the placement of multiple motor shafts with different diameters.

[0023] Further, a keyway 25 connected thereto is provided at the shaft end positioning hole 24.
