Description

Technical Field

[0001] The utility model belongs to the technical field of motor armature core detection, and in particular relates to a correction mechanism for the armature core of a brushed motor. Background Art

[0002] The armature core of the motor is one of the core components of the motor. It is usually made of conductive materials such as copper or copper alloy. The armature core is located in the rotor part of the motor and is responsible for carrying current and generating a magnetic field, thereby interacting with the magnetic field of the motor to achieve rotation. The rotating part of the DC brushed motor is the armature core, so the quality of the armature core directly affects the performance of the motor.

[0003] At present, many methods for correcting the armature core of a motor are to place the motor armature cores uniformly after detecting that the motor armature cores are defective, and then use heating correction to correct them. Since the diameter of some motor armature cores is small, the heating correction method can achieve the purpose, but there are more processes and a large investment, which is not conducive to use for small motor armature cores.

[0004] Therefore, a correction mechanism for the armature core of a brushless motor is designed to change the above technical defects. Utility Model Content

DETAILED DESCRIPTION

[0023] This specific implementation is a correction mechanism for the armature core of a brushless motor, and its structural diagram is shown in FIG. Figure 1-Figure 5 As shown, it includes a base plate 13, the top surface of the base plate 13 is equipped with a first cylinder 1, the side wall of the first cylinder 1 is slidably connected to a limit block 2, the output end of the first cylinder 1 is fixedly connected to the limit block 2, the side wall of the limit block 2 is fixedly connected to a mounting plate 3, the side wall of the mounting plate 3 is provided with a transmission assembly, the top surface of the base plate 13 is located at the rear side of the mounting plate 3 and a detection assembly is provided, the top surface of the base plate 13 is equipped with a support seat 14, the top surface of the support seat 14 is equipped with two support plates 15, the top of the support plate 15 is V-shaped, a correction assembly is provided near the rear side of the top surface of the support seat 14, and a grabbing assembly is provided on the front side of the base plate 13.

[0024] The left side of the bottom plate 13 needs to be used in conjunction with a conveyor belt to transport the undetected armature core, so that the left side clamp 25 can grab it and place it on the support plate 15 .

[0025] like Figure 1 and Figure 3 As shown, the transmission assembly includes two groove wheels 5 rotatably connected to the front side wall of the mounting plate 3, a rubber belt 6 is transmission-connected between the two groove wheels 5, a motor 7 is fixedly mounted on the rear side wall of the mounting plate 3, the output shaft of the motor 7 is fixedly connected to the right groove wheel 5, and a groove 4 is provided on the bottom surface of the mounting plate 3.

[0026] Specifically, when the armature core is inspected, after the armature core is placed in place, the first cylinder 1 first drives the transmission assembly to move downward through the limit block 2, so that the rubber belt 6 is tightly attached to the armature core, and then the motor 7 is started to drive the rubber belt 6 to rotate, and the friction between the rubber belt 6 and the armature core is used to drive the armature core to rotate.

[0027] like Figure 1 and Figure 2 As shown, the detection component includes a slide rail 8 mounted on a base plate 13, the side wall of the slide rail 8 is slidably connected to a slider 9, the side wall of the slider 9 is equipped with a detection pressure rod 10, the bottom end of the detection pressure rod 10 is installed with a displacement sensor 11, and the top end of the detection pressure rod 10 is installed with an indicator light 12.

[0028] When the transmission assembly drives the armature core to rotate, the slider 9 drives the detection pressure rod 10 to move downward, so that the displacement sensor 11 fits with the armature core and detects it. During the detection process, the indicator light 12 lights up and goes out after the detection is completed.

[0029] like Figure 4 As shown, the correction assembly includes two second cylinders 16 mounted on the top surface of the support seat 14 near the rear side, the output end of the second cylinder 16 is fixedly connected to a correction block 17, and the side walls opposite to the correction block 17 are respectively provided with arc grooves 18.

[0030] Specifically, the correction block 17 and the second cylinder 16 are detachably connected. Different correction blocks 17 are replaced for different types of armature cores, so that the arc groove 18 can correspond to the diameter of the armature core, which is convenient for correction. Generally, the offset position of the armature core is small. During the correction process, the force does not need to be too large to complete the correction. If the offset distance is too large, manual detection and correction can be used later.

[0031] like Figure 1 and Figure 5 As shown, the grabbing assembly includes a track 19, a movable block 20 is slidably connected to the track 19, a connecting plate 21 is fixedly connected to the top surface of the movable block 20, a third cylinder 22 is fixedly installed on the top surface of the connecting plate 21, a cross plate 23 is fixedly connected to the output end of the third cylinder 22, two fourth cylinders 24 are installed on the top surface of the cross plate 23 near both ends, and a clamp 25 is provided on the fourth cylinder 24, and the side wall of the clamp 25 is arc-shaped.

[0032] Specifically, when a defective product is detected, after correction, the right clamp 25 needs to place it in the scrap slot 26 to facilitate later manual re-inspection. After the defective product is placed in the scrap slot 26, the right clamp 25 needs to cooperate with the left clamp 25 to continue to move to the right to the position above the placement plate 27, so that the left clamp 25 can place the undetected armature core on the support plate 15.

[0033] like Figure 1 As shown, a waste slot 26 is provided near the right side of the top surface of the bottom plate 13 , and the waste slot 26 is inclined downward. A placement plate 27 is provided on the top surface of the bottom plate 13 and located on the right side of the waste slot 26 .

[0034] Working principle: A conveyor belt is provided on the left side of the bottom plate 13 for conveying the armature core. During operation, the third cylinder 22 is first started to drive the fourth cylinder 24 to move downward, so that the armature cores between the conveyor belt and the support plate 15 are all located between the clamps 25, and then the fourth cylinder 24 is operated to drive the clamps 25 to clamp the armature core. After that, the third cylinder 22 drives the armature core to rise through the fourth cylinder 24. At this time, the movable block 20 moves to the right on the track 19. When the armature core clamped on the left side is located above the support plate 15, the third cylinder 22 descends to place the undetected armature core on the support plate 15, and the detected armature core is placed on the placement plate 27. The good armature core on the placement plate 27 is taken away by an external manipulator.

[0035] Then, the first cylinder 1 is operated to drive the mounting plate 3 to move downward through the limit block 2, so that the rubber belt 6 is against the armature core, and then the motor 7 is started. The motor 7 drives the rubber belt 6 to rotate through the groove wheel 5, and the friction force of the rubber belt 6 is used to drive the armature core to rotate. Then, the slide rail 8 is operated to drive the detection pressure rod 10 to move downward through the slider 9, and the armature core is detected by the displacement sensor 11. If the armature core is detected to be a defective product, the third cylinder 22 drives the fourth cylinder 24 to move downward, and the right fourth cylinder 24 is operated to hold the armature core, and then the second cylinder 16 is operated. The second cylinder 16 drives the correction block 17 to wrap the end of the armature core for correction. At this time, the downward pressure limit of the right clamping jaw 25 is used to prevent the armature core from detaching. At the same time, the rubber belt 6 can be used to transmit it. After the correction is completed, the right clamping jaw 25 puts it into the waste slot 26 for subsequent re-inspection or manual correction.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
