Description

Technical Field

[0001] The utility model belongs to the technical field of commutators, and in particular relates to a commutator hook and other indexing mechanism which is easy to position. Background Art

[0002] An electric motor is a rotating electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or a distributed stator winding to generate a magnetic field and a rotating armature or rotor. The power range that an electric motor can provide is very large, from milliwatts to kilowatts. For example, machine tools and water pumps need to be driven by electric motors; electric locomotives and elevators need to be pulled by electric motors; electric fans, refrigerators, washing machines, and even various electric motor toys in family life cannot do without electric motors. The commutator (English: commutator), commonly known as the rectifier, is a component of a DC permanent magnet series motor that allows the motor to continue to rotate. When the coil passes through the current, it will rotate through the attraction and repulsion force under the action of the permanent magnet. When it rotates to balance with the magnet, the contact piece on the commutator corresponding to the original wire that carries the current is separated from the brush, and the brush is connected to the contact piece corresponding to the group of coils that generate the driving force. This is repeated over and over again, and the DC motor starts to rotate.

[0003] At present, the existing commutator hook calibration and equal indexing mechanism such as patent number: CN202121524533.1, a commutator outer hook calibration and equal indexing mechanism, including a frame, an outer hook equal indexing calibration position is provided on the frame, a calibration mold is provided in the outer hook equal indexing calibration position, a standard outer hook groove is provided in the calibration mold, an upper pressing assembly is provided above the outer hook calibration position, and a lower lifting assembly is provided below the outer hook calibration position; the upper pressing assembly includes an upper pressing head and an upper pressing driver for driving the upper pressing head to rise and fall; the lower lifting assembly includes a lower lifting head and a lower lifting driver for driving the lower lifting head to rise and fall;

[0004] Although this patent improves the efficiency of inspecting the commutator by using an upper pressing head to press the commutator into the correction mold and then using a lower lifting head to eject the commutator from the correction mold, during operation, it is necessary to first extend the transfer plate through a longitudinal drive so that the commutator is located in the transfer hole at one end of the transfer plate, and then drive the commutator to move through a transverse drive. However, when the longitudinal drive drives the transfer plate to retract, the commutator located in the transfer hole may be dragged by the retracting transfer plate, causing the position of the commutator on the frame to shift, and the shifted commutator cannot be accurately positioned in the transfer hole in subsequent operations. Utility Model Content

[0005] The purpose of the utility model is to provide a commutator hook calibration and other dividing mechanism which is easy to position, and aims to solve the problem proposed in the prior art that during the operation of the existing commutator hook calibration and other dividing mechanism, it is necessary to first extend the transmission plate through a longitudinal drive so that the commutator is located in the transmission hole at one end of the transmission plate, and then drive the commutator to move through a transverse drive. However, when the longitudinal drive drives the transmission plate to retract, the commutator located in the transmission hole may be dragged by the retracting transmission plate, thereby causing the position of the commutator on the frame to shift, and then the shifted commutator cannot be accurately positioned in the transmission hole in subsequent operations.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a commutator hook-calibrating and equal indexing mechanism that is easy to position, comprising a first frame, a commutator is arranged on the top of the first frame, a pressing driver is installed on the top and bottom of the first frame, a second frame is arranged on one side of the first frame, a longitudinal driver is installed on the top of the second frame, one end of the longitudinal driver is connected to a carrying plate, a transmission plate is arranged on the top of the carrying plate, and a transverse driver is arranged on the top of the second frame;

[0007] A double-headed motor is installed at the bottom of the first frame, and a rotating rod is connected to the output end of the double-headed motor, one end of the rotating rod is connected to the first bevel gear, the bottom of the first frame is fixedly connected to a support plate, and two mounting brackets are installed on the top of the first frame, one side of the two mounting brackets is provided with a screw rod, one end of the screw rod is connected to the second bevel gear, an opening is opened on the surface of the mounting bracket, the outer wall of the screw rod is threadedly connected to a connecting block, and one end of the connecting block is connected to a limiting plate.

[0008] As a preferred commutator hook-calibrating and other indexing mechanism for facilitating positioning of the utility model, one end of the rotating rod passes through the surface of the supporting plate.

[0009] As a preferred commutator hook-calibrating and other indexing mechanism that is easy to position in the utility model, one end of the screw rod extends through and to the bottom of the first frame.

[0010] As a preferred commutator hook calibration and equal indexing mechanism for easy positioning of the utility model, the first bevel gear is meshed with the second bevel gear.

[0011] As a preferred commutator hook calibration and other indexing mechanism that is easy to position in the utility model, one end of the connecting block is located inside the opening.

[0012] As a preferred indexing mechanism for a commutator hook calibration that is easy to position in the utility model, the limit plate is located on the top of the transmission plate.

[0013] As a preferred commutator hook-calibrating and other indexing mechanism of the utility model which is easy to position, one end of the screw rod forms a rotation connection structure with the mounting frame through a bearing.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By starting the double-headed motor to drive the rotating rod to rotate, due to the meshing relationship between the first bevel tooth and the second bevel tooth, the lead screw can be driven to rotate by the rotating rod. At this time, the connecting block on the outer wall of the lead screw will drive the limit plate to descend under the action of its rotation until the bottom of the limit plate contacts the top of the transmission plate and fits together. At this time, the transmission plate is recovered through the longitudinal drive, and the top of the commutator dragged by the transmission plate will be blocked by the limit plate, thereby avoiding the commutator being dragged and offset by the transmission plate, which is convenient for the subsequent positioning of the commutator.

[0024] It should be noted that the detailed working principle can be found in the cited patent;

[0025] A double-headed motor 8 is installed at the bottom of the first frame 1, and a rotating rod 9 is connected to the output end of the double-headed motor 8, and one end of the rotating rod 9 is connected to a first bevel gear 10. A support plate 11 is fixedly connected to the bottom of the first frame 1, and two mounting frames 12 are installed on the top of the first frame 1. A screw rod 13 is arranged on one side of the two mounting frames 12, and one end of the screw rod 13 is connected to a second bevel gear 14. An opening 15 is opened on the surface of the mounting frame 12, and a connecting block 16 is threadedly connected to the outer wall of the screw rod 13, and one end of the connecting block 16 is connected to a limiting plate 17;

[0026] It should be noted that the connection terminal of the double-headed motor 8 is connected to an external power supply and a control switch, the support plate 11 is used to support one end of the rotating rod 9; the two mounting frames 12 are symmetrically distributed; and a connecting block 16 is connected to each end of the limit plate 17.

[0027] Preferably: one end of the rotating rod 9 passes through the surface of the support plate 11, one end of the screw rod 13 extends through and extends to the bottom of the first frame 1, the first bevel gear 10 is meshed with the second bevel gear 14, one end of the connecting block 16 is located on the inner side of the opening 15, the limit plate 17 is located on the top of the transmission plate 7, and one end of the screw rod 13 forms a rotating connection structure with the mounting frame 12 through a bearing.

[0028] During specific use, the double-headed motor 8 is started to drive the rotating rod 9 to rotate. Since the first bevel gear 10 and the second bevel gear 14 are in a meshing relationship, the screw rod 13 can be driven to rotate by the rotating rod 9. At this time, the connecting block 16 on the outer wall of the screw rod 13 will drive the limit plate 17 to descend under the action of its rotation until the bottom of the limit plate 17 contacts the top of the transmission plate 7 and fits together. At this time, the transmission plate 7 is recovered by the longitudinal drive 5, and the top of the commutator 2 dragged by the transmission plate 7 will be blocked by the limit plate 17, thereby preventing the commutator 2 from being dragged and offset by the transmission plate 7.

[0029] Working principle: When using the commutator hook and other dividing mechanisms that are easy to position, first, the conveying plate 7 is extended through the longitudinal driver 5 so that the commutator 2 on the first frame 1 is in the conveying hole, and then the commutator 2 is driven to move through the transverse driver 18. When the conveying plate 7 is to be recovered, the rotating rod 9 is driven to rotate by starting the double-headed motor 8. Since the first bevel gear 10 and the second bevel gear 14 are in a meshing relationship, the screw rod 13 can be driven to rotate by the rotating rod 9. At this time, the connecting block 16 on the outer wall of the screw rod 13 will drive the limit plate 17 to descend under the action of its rotation until the bottom of the limit plate 17 contacts the top of the conveying plate 7 and fits. At this time, when the conveying plate 7 is recovered by the longitudinal driver 5, the top of the commutator 2 dragged by the conveying plate 7 will be blocked by the limit plate 17, thereby avoiding the commutator 2 being dragged and offset by the conveying plate 7, which is convenient for the subsequent positioning of the commutator 2.
