DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 As shown, the carbon brush holder on the existing DC motor is composed of an auxiliary disk 3 and a base 4. The auxiliary disk 3 is located between the base 4 and the DC motor. The auxiliary disk 3 is used to connect the base 4 and the DC motor. The base 4 is a cylinder. The horizontal area of ​​the base 4 is smaller than the horizontal area of ​​the auxiliary disk 3. At this time, the base 4 is located at the center of the auxiliary disk 3.

[0025] Since the carbon brush is easy to wear and tear, it needs to be replaced more frequently, and the blocking piece 2 is difficult to be pushed out from the limit groove. The DC motor carbon brush assembly assembly of the present application can be installed on the carbon brush holder to quickly and conveniently push out the blocking piece 2. Figures 2 to 9 As shown:

[0026] The present invention comprises a positioning frame, which is docked on the carbon brush holder 1. The positioning frame is composed of a positioning component 5 and a control component 6. The control component 6 is connected to the positioning component 5. The positioning component 5 comprises an inner ring sleeve 7, which can be sleeved on the base 4 of the carbon brush holder 1. An outer ring sleeve 8 is connected to the inner ring sleeve 7. The diameter of the outer ring sleeve 8 is larger than the diameter of the inner ring sleeve 7, and the central axis of the inner ring sleeve 7 is on the same straight line as the central axis of the outer ring sleeve 8. The outer ring sleeve 8 is sleeved on the auxiliary disk 2. The outer ring sleeve 8 is connected to the inner ring sleeve 7 by a pull rod. A side buckle plate 9 is also connected to the outer ring sleeve 8. The side buckle plate 9 extends along the length direction of the DC motor. The outer ring sleeve 8 is cylindrical. The control component 6 is connected to the outer ring sleeve 8. The side buckle plate 9 is a part of the control component 6. The side buckle plate 9 is a long strip-shaped plate body. A strip-shaped notch 14 is provided on the side buckle plate 9. The strip-shaped notch 14 passes through the side buckle plate 9. The strip notch 14 is arranged to be located at the center of the side clip plate 9, and at this time the strip notch 14 corresponds to the notch on the carbon brush holder. It should be noted that there is a certain gap between the inner side of the side clip plate 9 and the carbon brush holder 1, and a sliding sheet 11 is installed at the strip notch 14 of the side clip plate 9. The sliding sheet 11 can move in the strip notch 14 along the length direction of the strip notch 14, and an adsorption component 12 is installed on the sliding sheet 11, and the adsorption component 12 is connected to the pressure rod 13, and the pressure rod 13 is located at the center of the sliding sheet 11 and penetrates the sliding sheet 11. After the adsorption component is adsorbed and connected to the blocking sheet, when the sliding sheet 11 moves in the strip notch 14, the blocking sheet 2 moves accordingly. At this time, the copper sheet between the carbon brush and the blocking sheet 2 leaks out, the copper sheet is removed, and then the old carbon brush is taken out, and the new carbon brush is assembled in the notch, and the carbon brush can be replaced.

[0027] When the sliding piece 11 is controlled to move along the length direction of the strip notch 14, in order to ensure the stability of the moving trajectory of the sliding piece 11, limiting grooves 10 are provided on the inner and outer surfaces of the side buckle plate 9, and the strip notch 14 connects the two limiting grooves 10. At this time, the sliding piece 11 is located in the limiting groove 10, and the length direction of the limiting groove 10 is on the same straight line as the length direction of the side buckle plate 9. Since there are two blocking pieces 2 on the DC motor and the two blocking pieces 2 are symmetrically arranged, there are also two side buckle plates 9. At this time, the pressure rod 13 passes through the strip notch, and the pressure rod 13 can move along the length direction of the limiting groove 10. The pressure rod 13 is passed through the through hole, so that the pressure rod 13 can be controlled to slide along the axial direction of the through hole. When pressure is applied to the outer end of the pressure rod 13, the pressure rod 13 moves toward the carbon brush holder 1. Since the adsorption component 12 is connected to the inner end of the pressure rod 13, the adsorption component will move toward the blocking piece 2 until the adsorption component 12 is adsorbed and connected with the blocking piece 2. At this time, when the sliding piece and the pressure rod 13 are controlled to move along the length direction of the strip notch, the blocking piece can be driven to move, so that the blocking piece is moved out of the slot.

[0028] In addition, the side clip plate 9 is connected to the outer ring sleeve 8, and the width of the strip notch 14 is smaller than the width of the limiting groove 10, but the width of the strip notch 14 should be larger than the width of the carbon brush, otherwise the carbon brush will not be able to pass through the strip notch and be inserted into the groove of the carbon brush holder.

[0029] In order to ensure the stability of the sliding piece 11 in the limiting groove 10, the sliding piece 11 includes an upper limit plate 15 and a lower limit plate 16, and a movable plate 17 is arranged between the upper limit plate 15 and the lower limit plate 16. The three are disc-shaped, and the movable plate 17 is fixedly connected to the upper limit plate 15 and the lower limit plate 16 at the same time. The diameters of the upper limit plate 15 and the lower limit plate 16 are both larger than the diameter of the movable plate 17. The movable plate 17 is located in the strip-shaped notch 14, and the diameter of the movable plate 17 is equal to The width of the strip notch 14, the upper limit plate 15 and the lower limit plate 16 are respectively located in the limit grooves 10 set on the inner and outer sides of the side buckle plate 9, wherein the upper limit plate 15 is located on the outer side of the side buckle plate 9, and the lower limit plate 16 is located on the inner side of the side buckle plate 9. A plug hole 18 is set at the center position of the upper limit plate 15, the movable plate and the lower limit plate 16. After the plug hole 18 penetrates the upper limit plate 15, the movable plate and the lower limit plate 16 at the same time, a through hole is formed on the sliding sheet 11, and the pressure rod 13 is located The pressure rod 13 is in the insertion hole 18, and the pressure rod 13 can move along the length direction of the insertion hole 18. The handle on the pressure rod 13 is located on the outside of the upper limit plate 15. The adsorption component 12 is connected to the end of the pressure rod 13 close to the carbon brush 1. The adsorption component 12 is a suction cup. The pressure rod 13 can be connected to the carbon brush holder 1 through the suction cup. When the pressure rod 13 moves radially inward in the insertion hole 18, that is, when the pressure rod 13 moves toward the direction of the carbon brush holder 1, the suction cup is adsorbed on the blocking piece 2 of the carbon brush holder 1. When the sliding piece 11 moves along When moving along the length direction of the limiting groove 10, the blocking piece 2 can be pushed out of the limiting groove of the DC motor, and then the copper sheet installed on the carbon brush holder 1 can be taken out, and the carbon brush can fall out of the groove, thereby completing the process of taking out the carbon brush, and then a new carbon brush is placed in the groove, and the spring and the copper sheet are installed on the groove, so that the blocking piece 2 is aligned with the limiting groove, and the sliding piece 11 is moved in the reverse direction, and the blocking piece 2 can be installed on the carbon brush holder 1, and so on, the replacement of the carbon brush of the DC motor can be completed.

[0030] In addition, the inner ring sleeve 7 is a cylinder, and a groove 19 matching the base 4 of the carbon brush holder 1 is provided on the inner surface of the inner ring sleeve 7. The carbon brush holder 1 can be installed on the inner ring sleeve 7 and the outer ring sleeve 8. The setting of the inner ring sleeve 7 can ensure the stability of the sliding plate 11 when it moves along the length direction of the limiting groove 10.

[0031] During implementation, the positioning component 5 is sleeved on the carbon brush holder 1. At this time, the base 4 is located in the inner ring sleeve 7, and part of the auxiliary disk 3 is located in the outer ring 8. The pressure rod 13 is pushed radially to move the pressure rod 13 toward the carbon brush holder 1, so that the suction cup is adsorbed on the blocking piece 2 on the carbon brush holder 1, and then the pressure rod 13 and the sliding piece 11 are slid along the length direction of the limiting groove 10, so that the blocking piece 2 can be pushed out of the limiting groove, and the copper sheet and spring above the groove are removed, so that the old carbon brush can be conveniently taken down, and the new carbon brush is installed in the groove 19, and the spring and the copper sheet are installed on the groove, so that the blocking piece 2 is aligned with the limiting groove, and the pressure rod 13 and the sliding piece 11 are moved in the opposite direction, and the blocking piece 2 can be installed on the carbon brush holder 1, and so on, the replacement of the carbon brush of the DC motor can be completed.
