Description

Technical Field

[0001] The present invention relates to the technical field of generator equipment, namely a portable generator carbon brush grinding device, which can be applied to the replacement of collector ring carbon brushes in generators in the power industry. Background Art

[0002] When replacing the collector ring carbon brushes of a generator, it is necessary to grind the plane where the new carbon brushes contact the collector ring. Otherwise, the contact area between the newly installed carbon brushes and the collector ring is small, which may cause the temperature at the position of the newly replaced carbon brushes to rise abnormally during the normal operation of the generator. In the prior art, when grinding new carbon brushes, only protection can be carried out around the collector ring, and sandpaper is placed on the collector ring body to grind the new carbon brushes. Since carbon powder will splash everywhere during carbon brush grinding, it greatly affects the safety during the normal operation of the generator. Summary of the Invention

[0003] The purpose of the present invention is to provide a portable generator carbon brush grinding device that is safer and more convenient to use in view of the above deficiencies.

[0004] The technical solution of the present invention is: a portable generator carbon brush grinding device, which is characterized by including a support plate. There are four suction cups for sucking the ground at the four corners under the support plate. The front side of the upper end surface of the support plate is connected with a carbon brush grinding arc template. The rear end of the carbon brush grinding arc template is connected with a screw rod for adjusting the arc radius. The upper part of the carbon brush grinding arc template is provided with a sandpaper fixing clip. There is a carbon block clip corresponding to the front end of the carbon brush grinding arc template. There are wheels at the bottom of the carbon block clip for swinging left and right. A handle is installed and fixed on the carbon block clip. The front end of the carbon block clip is connected with a long screw rod, and the other end of the long screw rod is provided with an adjusting nut for adjusting the length.

[0005] In the above solution, it further includes: There is a slideway at the bottom of the carbon block clip for the wheels to slide.

[0006] The screw rods are two in a fan-shaped opening, and there are nuts on the screw rods for adjusting the length of the screw rods.

[0007] The suction cups are trapezoidal in the height direction.

[0008] The advantages of the present invention are: The carbon brush grinding arc template of this device can adjust the curvature by adjusting the long screw rod, and can adapt to the sizes of collector rings of generators used in various power plants, with a wide range of applications. There is a carbon block clip corresponding to the front end of the carbon brush grinding arc template. There are wheels at the bottom of the carbon block clip for swinging left and right, and there is a slideway at the bottom of the carbon block clip for the wheels to slide. The carbon block slides freely, saving time and effort, and having a good grinding effect.

[0009] This device is installed with 4 suction cups and can be used on the floors of various workshops such as warehouses and self-leveling floors, with low usage conditions.

[0010] It can be used away from the production area, is safer to use, and is easy to protect and clean.

[0011] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Description of the Drawings

[0012] Figure 1 It is a top view structural sketch of the present invention.

[0013] Figure 2 is Figure 1 a left view structural sketch. Detailed Embodiments

[0014] Refer to Figure 1 and 2 The names of the components are as follows: suction cup 1, sandpaper fixing clip 2, screw 3, carbon brush grinding arc template 4, slideway 5, carbon block clip 6, handle 7, support plate 8, wheel 9, long screw 10, adjusting nut 11, nut 12, center of circle 13.

[0015] Refer to Figure 1 and 2 The portable generator carbon brush grinding device includes a quadrilateral support plate 8. There are four suction cups 1 for adsorbing the ground at the four corners under the support plate 8. The suction cups 1 are trapezoidal in the height direction. At the front side of the upper end surface of the support plate 8, a carbon brush grinding arc template 4 is connected. At the rear end of the carbon brush grinding arc template 4, a screw 3 for adjusting the arc radius is connected. The screw 3 is composed of two fan-shaped opened screws. The two angularly arranged screws 3 are at the same center of circle 13 and can adapt to the sizes of different types of slip rings. The center of circle 13 is fixed on the support plate 8. There is a nut 12 on the screw 3 for adjusting the length of the screw 3. Two sandpaper fixing clips 2 are installed at intervals on the upper part of the carbon brush grinding arc template 4. The sandpaper on the side in contact with the carbon block can meet the requirements of convenient and simple sandpaper replacement. Corresponding to the front end of the carbon brush grinding arc template 4, there is a carbon block clip 6. At the bottom of the carbon block clip 6, there are wheels 9 for left and right swinging, and at the bottom of the carbon block clip 6, there is a slideway 5 for the wheels to slide. A handle 7 is installed and fixed on the carbon block clip 6. The front end of the carbon block clip 6 is connected with a long screw 10 (to distinguish it from the shorter screw 3, and their functions are the same). The other end of the long screw 10 is provided with an adjusting nut 11 for adjusting the length, which can adjust the distance between the carbon block clip 6 and the carbon brush grinding arc template 4. A handle 7 is installed and fixed on the carbon block clip 6. A constant force spring is installed on the carbon block clip 6, which will apply a constant force to push the carbon block forward. After installing the carbon block, only one-way sliding is required to grind the carbon block. The slideway 5 is an arc-shaped smooth and solid plate. In fact, as long as it is smooth and solid, a rectangular shape is also acceptable. It mainly relies on the wheels under the carbon block clip 6 for sliding, and the radius length is adjusted through the adjusting nut 11.

[0016] Usage steps: First, fix the entire device on the ground with the suction cup 1. Then, adjust the arc of the carbon brush grinding arc template 4 through two screws 3 according to the size of the slip ring. After determining the radius of the slip ring, adjust the carbon brush grinding arc template 4 by adjusting the length of the screw 3. After determining the arc of the carbon brush grinding arc template 4, fix the sandpaper on the sandpaper fixing clip 2, and only fix one piece of sandpaper with two fixing clips 2 at a time. After the carbon brush grinding arc template 4 is adjusted, fix the carbon block to be ground on the carbon block clamp 6 and clamp it tightly. Adjust the distance between the carbon block clamp 6 and the carbon brush grinding arc template 4 by means of the long screw 10 and the adjusting nut 11. Finally, hold the handle 7 and slide the grinding carbon block unidirectionally to achieve grinding.

[0017] The above description is only the specific implementation mode of the present invention, and various examples do not constitute a limitation to the substantial content of the present invention.
