Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically an electric brush grinding device. Background Technology

[0002] A brush is an important component of an electric motor, responsible for conducting current between rotating and stationary parts. Because it is mostly made of graphite, it is also called a carbon brush. Brushes are mostly mounted on commutators or slip rings and are sliding contact bodies with characteristics such as smoothness, wear resistance, and good conductivity.

[0003] In the prior art, the way the abrasive belt is installed in the brush grinding device is not convenient for fixing, and the grinding state is a horizontal grinding state. This causes the carbon powder generated during grinding to not fall freely, so it is inconvenient to clean the residue on the surface of the grinding cylinder. Therefore, those skilled in the art have provided a brush grinding device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an electric brush grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric brush grinding device, including a mounting base, a first motor fixedly embedded in the top of the mounting base, a grinding cylinder fixedly connected to the top of the output shaft of the first motor, two rectangular plates slidably connected through the grinding cylinder, and the upper and lower sides of the two rectangular plates extending to the top and bottom of the grinding cylinder respectively, multiple tension springs vertically arranged and fixedly connected on opposite sides of the two rectangular plates, clamping rings fixedly connected to the top and bottom of the rectangular plates, an abrasive belt wound around the outer wall of the grinding cylinder, the surface of the abrasive belt tightly fitting the inner sides of the multiple clamping rings, a receiving box throughly snapped into the top of the mounting base, a moving block slidably connected to the top of the mounting base, a mounting frame fixedly connected to the top of the moving block, multiple second clamping plates vertically arranged and fixedly connected to the side of the mounting frame near the grinding cylinder, an adjusting screw rotatably connected to the side of the mounting frame away from the second clamping plates, and a first clamping plate threaded onto the outer wall of the adjusting screw.

[0006] As a further embodiment of this utility model: a rectangular hole is provided through the top of the grinding cylinder, and one side of the two rectangular plates is slidably connected to the inner wall of the rectangular hole, with the upper and lower sides of the two rectangular plates passing through the upper and lower openings of the rectangular hole.

[0007] As a further improvement of this utility model: the top of the mounting base is provided with a through hole, and the receiving box is through and snapped into the receiving box. The through hole partially surrounds the first motor. The receiving box is located below the grinding cylinder, and both the through hole and the receiving box are U-shaped.

[0008] As a further embodiment of this utility model: a connecting seat is fixedly connected to the top of the mounting base, and a second motor is fixedly embedded in the connecting seat. A drive screw is fixedly sleeved on the outer wall of the output shaft of the second motor, and the drive screw thread passes through the moving block.

[0009] As a further improvement of this utility model: two limiting rods are symmetrically fixedly connected to the inner side of the first clamping plate, and both limiting rods pass through the mounting frame and extend to one side of the mounting frame.

[0010] As a further improvement of this utility model: multiple teeth are fixedly connected to the inner sides of the second clamping plate, the first clamping plate, and the mounting bracket, and the multiple teeth are arranged vertically.

[0011] As a further embodiment of this utility model: a limiting block is fixedly connected to the bottom of the moving block, and the bottom of the limiting block penetrates the top of the mounting base; the grinding cylinder is located on one side of the mounting frame; a support plate is fixedly connected to the top of the output shaft of the first motor, and the top of the support plate is fixedly connected to the bottom of the grinding cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the sanding belt needs to be installed, pull the two rectangular plates away from each other. When the two rectangular plates move away from each other, multiple tension springs will be stretched, and multiple clamping rings will also move away from each other. At this time, a space will be left between the inner wall of the clamping rings and the outer wall of the grinding cylinder. Then, the sanding belt is inserted into this space and wrapped around the outer wall of the grinding cylinder. Finally, the rectangular plates are released, and the two rectangular plates will move closer to each other due to the tension of multiple tension springs. At this time, multiple clamping rings will also move closer to each other and stick tightly to the surface of the sanding belt, thus completing the clamping and fixing of the sanding belt. When the first motor is started, it can drive the support plate, grinding cylinder, and sanding belt to rotate together to grind the brushes attached to the surface of the sanding belt. The debris generated during grinding will fall into the receiving box for collection.

[0014] This invention is simple to use. The grinding cylinder is vertically set, and the surface can be clamped by multiple clamping rings to install a sanding belt for grinding the brush. This facilitates the installation and replacement of the sanding belt. When the adjusting screw is rotated, the first clamping plate can be moved closer to the second clamping plate to clamp and fix multiple brushes. This allows multiple brushes to be clamped and processed at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the present invention, an electric brush grinding device includes a mounting base 1. A first motor 2 is fixedly embedded in the top of the mounting base 1. A grinding cylinder 18 is fixedly connected to the top of the output shaft of the first motor 2. Two rectangular plates 17 are slidably connected through the grinding cylinder 18, and the upper and lower sides of the two rectangular plates 17 extend to the top and bottom of the grinding cylinder 18, respectively. Multiple tension springs 20 are vertically arranged and fixedly connected to one side of the two rectangular plates 17. Clamping rings 4 are fixedly connected to the top and bottom of the rectangular plates 17. A sanding belt 3 is wound around the outer wall of the grinding cylinder 18. The surface of the sanding belt 3 and the inner side of multiple clamping rings 4 are tightly fitted. A receiving box 5 is snapped through the top of the mounting base 1. A moving block 10 is slidably connected to the top of the mounting base 1. A mounting frame 13 is fixedly connected to the top of the moving block 10. Multiple second clamping plates 15 are vertically arranged and fixedly connected on the side of the mounting frame 13 near the grinding cylinder 18. An adjusting screw 11 is rotatably connected on the side of the mounting frame 13 away from the second clamping plates 15. A first clamping plate 12 is threaded on the outer wall of the adjusting screw 11.

[0023] In this embodiment, a rectangular hole 19 is provided through the top of the grinding cylinder 18, and one side of the two rectangular plates 17 is slidably connected to the inner wall of the rectangular hole 19. The upper and lower sides of the two rectangular plates 17 are through the upper and lower openings of the rectangular hole 19.

[0024] In this embodiment, the top of the mounting base 1 has a through hole 16, and the receiving box 5 is through and snapped into the receiving box 5. The through hole 16 partially surrounds the first motor 2. The receiving box 5 is located below the grinding cylinder 18, and both the through hole 16 and the receiving box 5 are U-shaped.

[0025] In this embodiment, a connecting seat 8 is fixedly connected to the top of the mounting base 1, and a second motor 7 is fixedly embedded in the connecting seat 8. A drive screw 9 is fixedly sleeved on the outer wall of the output shaft of the second motor 7, and the drive screw 9 is threaded through the moving block 10.

[0026] In this embodiment, two limiting rods 14 are symmetrically fixedly connected to the inner side of the first clamping plate 12, and both limiting rods 14 pass through the mounting frame 13 and extend to one side of the mounting frame 13.

[0027] In this embodiment, multiple teeth 22 are fixedly connected to the inner sides of the second clamping plate 15, the first clamping plate 12, and the mounting bracket 13, and the multiple teeth 22 are arranged vertically. The two sides of the multiple brushes are attached to the inner sides of the second clamping plate 15 and the mounting bracket 13. Then, the adjusting screw 11 is rotated to move the first clamping plate 12 closer to the second clamping plate 15. The limiting rod 14 passes through the mounting bracket 13 and can limit the first clamping plate 12. This can prevent the first clamping plate 12 from rotating together when the adjusting screw 11 is rotated. At that time, the first clamping plate 12 will approach the multiple brushes to be attached, thereby completing the clamping and fixing of the multiple brushes. In addition, the teeth 22 are provided on the inner sides of the second clamping plate 15, the mounting bracket 13, and the first clamping plate 12, which can play an anti-slip role when clamping the brushes.

[0029] The working principle of this utility model is as follows: When the second motor 7 is started, it can drive the drive screw 9 to rotate. After the drive screw 9 rotates, it can drive the moving block 10 and the mounting bracket 13 to move. After the mounting bracket 13 moves, it can drive the clamped brush to move closer to and fit against the grinding cylinder 18. The limiting block 6 penetrates through the top of the mounting base 1 and can limit the moving block 10, and prevent the moving block 10 from rotating together when the drive screw 9 rotates. When the sanding belt 3 needs to be installed, the two rectangular plates 17 are pulled away from each other. When the two rectangular plates 17 move away from each other, multiple tension springs 20 will be stretched, and multiple clamping rings 4 will move away from each other. At that time, a space will be left between the inner wall of the clamping ring 4 and the outer wall of the grinding cylinder 18. Then, the sanding belt 3 is inserted into the space and wrapped around the outer wall of the grinding cylinder 18. Finally, the rectangular plate 17 is released, and the two rectangular plates 17 will approach each other through the tension of multiple tension springs 20. At that time, multiple clamping rings 4 will also approach each other and stick tightly to the surface of the sanding belt 3, thereby completing the clamping and fixing of the sanding belt 3. When the first motor 2 is started, it can drive the support plate 21, the grinding cylinder 18, and the sanding belt 3 to rotate together to grind the brush attached to the surface of the sanding belt 3. The debris generated during grinding will fall into the receiving box 5 for collection. The receiving box 5 can be snapped into the card hole 16 and can be pulled out directly.
