Description

Technical Field

[0001] The utility model belongs to the technical field of micro-commutator production devices, and particularly relates to a micro-commutator inner hole detection device. Background Technique

[0002] A commutator, also known as a "commutator", is an important component on the armature of a DC motor and an AC commutator motor. It is composed of many copper sheets separated by mica sheets and is in a cylindrical or disc shape. Each copper sheet is connected to a certain number of armature winding elements. When the armature rotates, the copper sheets successively contact the fixed brushes. In a DC motor, the alternating current in the armature winding is changed into direct current between the brushes through the brushes and the commutator. In an AC commutator motor, the frequency of the alternating current between the brushes meets the working requirements.

[0003] During the production process of a micro-commutator, it is necessary to detect the inner hole of the micro-commutator to see if the size of the inner hole is qualified and whether subsequent processing can be carried out. Existing detection devices can only fix and detect micro-commutators of a single size, with a small scope of application and being unfavorable for production. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Combined with Figures 1 to 7A micro-commutator inner hole detection device shown in the figure includes an operation table 1, with several support legs 2 provided below the operation table 1.

On the side of the upper end of the connecting plate 4 close to the operation table 1, there is a fixing plate 5. Below the fixing plate 5, there are two detection devices 6. The detection device 6 includes a first electric telescopic rod 61. Below the first electric telescopic rod 61, there is an operation plate 62. In the middle position of the lower surface of the operation plate 62, there is a circular groove 63. On both sides of the circular groove 63, there are through-connected limit grooves 64. On the side surfaces of the limit grooves 64, there are through-connected moving grooves 66. On the side surfaces of the moving grooves 66, there are through-connected cylindrical grooves 67. Below the circular groove 63, there is a testing device 68. Inside the moving groove 66, there is a movable connection with a push plate 69. Inside the cylindrical groove 67, there is a movable connection with a cylinder 610. Right below the detection device 6, there is a fixing device 7. The fixing device 7 includes a fixing block 71. On the upper surface of the fixing block 71, there is a sliding groove 72. On both sides of the fixing block 71, there are symmetrically arranged support plates 73. Above the support plates 73, there are symmetrically arranged second electric telescopic rods 74. On the sides of the second electric telescopic rods 74, there are clamping plates 75. Below the clamping plates 75, there are sliders 76. On one end of the fixing plate 5 close to the controller 3, there are symmetrically arranged two indicator lights 8.

[0027] Among them, the testing device 68 includes a testing cylinder 681. Inside the lower ends of both sides of the testing cylinder 681, there are contact sensors 682. In the middle above the testing cylinder 681, there is a main adjusting column 683. On both sides of the adjusting column 683, there are symmetrically arranged placing grooves 684. Inside the placing grooves 684, there are springs 685. On the side surfaces of the springs 685, there are symmetrically arranged arc-shaped limit blocks 686; the sizes of the arc-shaped limit blocks 686 match those of the placing grooves 684 and the limit grooves 64. The arc-shaped limit blocks 686 are located inside the limit grooves 64 and are movably connected to each other. The testing cylinder 681 is located inside the circular groove 63 and is movably connected to and fits with it. The arc-shaped surfaces on the side surfaces of the arc-shaped limit blocks 686 are in mutual contact with the side surface of the testing cylinder 681; the testing device can be replaced according to the inner holes of micro-commutators of different sizes, so that the detection device can detect whether the inner hole sizes of micro-commutators of different sizes are qualified.

[0028] The fixing blocks 71 are all fixedly connected to the operation table 1. The sliders 76 are all located inside the sliding grooves 72 and are movably connected to and fit with each other. The clamping plates 75 are located on the upper surface of the fixing blocks 71 and are movably connected to them; the first electric telescopic rods 61 are all fixedly connected to the fixing plate 5; the push plate 69 is fixedly connected to the cylinder 610. The size of the push plate 69 matches the size of the moving groove 66; the length of the cylinder 610 is greater than the sum of the lengths of the cylindrical groove 67 and the moving groove 66. The cylindrical groove 67 is through-connected between the operation plate 62; the side surfaces of the moving grooves 66 are all in contact with the outermost ends on both sides of the circular groove 63. Figure 3 The unmarked circular columns above are micro-commutators.

[0029] Working principle: When the present utility model is in use, first replace the test device 68 according to the inner hole size of the micro-commutator. When replacing, first push the two cylinders 610 towards the circular groove 63, driving the push plate 69 to move to both sides of the circular groove 63. When the push plate 69 moves, the arc-shaped limiting block 686 located inside the limiting groove 64 can be moved into the placement groove 684. Then rotate the test cylinder 681 so that the arc-shaped limiting block 686 moves away from the side of the limiting groove 64, and then move down to take out the test cylinder 681. Then take out the test cylinder 681 suitable for the inner hole of this batch of micro-commutators, then insert the arc-shaped limiting block 686 into the placement groove 64, making the spring 685 in a compressed state. Then put the adjusting column 683 into the circular groove 63, and then rotate the test cylinder 681. When the arc-shaped limiting block 686 moves to the side of the limiting groove 64, the arc-shaped limiting block 686 will move into the limiting groove 64 under the action of the spring 685 to fix the test cylinder 681. After replacing all the test cylinders 681, the micro-commutator to be detected can be placed above the fixed block 71. Then, through the controller 3, the second electric telescopic rods 74 on both sides of the fixed block 71 are controlled to fix the micro-commutator and move the commutator to directly below the test cylinder 681. Then, the controller is used to control the first electric telescopic rod 61 to descend, driving the test cylinder 681 to descend into the inner hole of the micro-commutator. When the inner hole size of the micro-commutator is qualified, the contact sensor 682 will contact the inner hole of the commutator, and then the indicator light will remain off. When the inner hole of the micro-commutator is too large, the contact sensor 682 on the side of the test cylinder 681 will not contact the inner wall when it descends into the inner hole. When the inner hole is too small, the test cylinder 681 cannot descend into the inner hole, and the contact sensor 682 will not contact the inner wall either. In both cases, the indicator light will light up, indicating that the inner hole of this micro-commutator is unqualified. The unqualified micro-commutators can be taken out, and the qualified ones can be taken out for subsequent processing. In the present utility model, the control connection method between the controller and the electric telescopic rod is the prior art and will not be described in detail. The control connection method between the indicator light and the contact sensor in the present utility model is the prior art and will not be described in detail. The electric telescopic rods, indicator lights, contact sensors, and electric telescopic rods in the present utility model are all the prior art and will not be described in detail.
