Description

Technical Field

[0001] The utility model relates to the technical field of grinders, and specifically discloses a grinder for steel processing. Background Art

[0002] A grinder is a manual or electric tool used for grinding the surface of metals. During the process of grinding the surface of a steel pipe with an existing grinder, only the hand is used to control the grinder, and it is easy for the grinding disc to slide on the surface of the steel pipe, making it inconvenient to manually perform the grinding operation, and it is also difficult to manually control the grinding depth. Content of the Utility Model

[0003] In view of the above defects or deficiencies in the prior art, the present application aims to provide a grinder for steel processing, which includes a grinder body, a handle arranged on the outer side of the grinder body, and a grinding disc fixedly installed on the grinder body. An installation boss is arranged on the outer side of the grinder body, a U-shaped frame is clamped on the outer side of the installation boss, an adjusting mechanism is installed on the outer side of the U-shaped frame, and a support sleeve located below the grinding disc is rotatably connected to the inside of the adjusting mechanism through a fixing rod.

[0004] Preferably, the adjusting mechanism includes a guide post threadedly sleeved inside the installation boss and movably sleeved inside the U-shaped frame. A U-shaped plate located on the outer side of the U-shaped frame and fixedly sleeved on the outer side of the fixing rod is sleeved on the outer side of the guide post, and a lead screw with its bottom end rotatably connected inside the U-shaped frame is threadedly sleeved inside the U-shaped plate.

[0005] Preferably, a guide groove adapted to the guide post penetrates through the inside of the U-shaped plate.

[0006] Preferably, damping bearings fixedly sleeved on the inner sides of the support sleeve are fixedly sleeved on the outer sides of both ends of the fixing rod, and a rubber sleeve is arranged on the outer side of the support sleeve. Advantageous Effects

[0007] 1. For this grinder for steel processing, the contact between the support sleeve and the surface of the steel pipe can limit and support the grinder body, so that during the grinding operation of the grinder, there are multiple points of limit support for the grinder body itself, making it not easy for the grinding disc to slide. And by controlling the grinder body to rotate around the axis of the fixing rod, the grinding depth of the grinding disc can be controlled, which is convenient for the grinding operation.

[0008] 2. For this grinder for steel processing, the damping bearings make it not easy for the support sleeve to rotate, and the rubber sleeve can increase the friction with the surface of the steel pipe, so that when the rubber sleeve contacts the surface of the steel pipe, the support sleeve is not easy to roll and slide, ensuring that the support sleeve can stably limit and support the grinder body.

Detailed implementation manners

[0016] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0017] In the drawings of the embodiments of the present utility model: Different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the sectional views of the components in the figure.

[0018] Please refer to Figures 1-5 , a grinder for steel processing, including a grinder body 1, a handle 2 arranged outside the grinder body 1, and a grinding disc 3 fixedly installed on the grinder body 1. An installation boss 4 is arranged outside the grinder body 1, a U-shaped frame 5 is clamped outside the installation boss 4, an adjustment mechanism 6 is installed outside the U-shaped frame 5, and a support sleeve 8 located below the grinding disc 3 is rotatably connected inside the adjustment mechanism 6 through a fixed rod 7.

[0019] Among them, the adjusting mechanism 6 includes a guide post 61 that is threadedly sleeved inside the mounting boss 4 and movably sleeved inside the U-shaped frame 5. A U-shaped plate 62 is sleeved outside the guide post 61 and is fixedly sleeved outside the fixed rod 7 and outside the U-shaped frame 5. A lead screw 63 is threadedly sleeved inside the U-shaped plate 62, and the bottom end of the lead screw 63 is rotatably connected inside the U-shaped frame 5. The guide post 61 can limit and fix the U-shaped frame 5 while limiting and guiding the U-shaped plate 62. And the lead screw 63 can limit the U-shaped plate 62 to prevent the U-shaped plate 62 from rotating around the axis of the guide post 61. At the same time, the position of the support sleeve 8 can be adjusted by rotating the lead screw 63.

[0020] Among them, a guide groove 9 adapted to the guide post 61 penetrates inside the U-shaped plate 62. Through the cooperation of the guide groove 9 and the guide post 61, the U-shaped plate 62 can drive the support sleeve 8 to move under the rotation of the lead screw 63, thereby adjusting the contact part between the grinding disc 3 and the steel pipe. When the polishing machine body 1 rotates around the axis of the fixed rod 7, the grinding disc 3 can contact the surface of the steel pipe.

[0021] Among them, damping bearings 10 fixedly sleeved outside both ends of the fixed rod 7 are fixedly sleeved inside the support sleeve 8. Through the damping bearings 10, the support sleeve 8 can slowly rotate around the axis of the fixed rod 7, ensuring that the support sleeve 8 can stably support the polishing machine body 1. A rubber sleeve 11 is arranged outside the support sleeve 8. The rubber sleeve 11 can increase the friction with the steel pipe. When the rubber sleeve 11 contacts the steel pipe, the polishing machine body 1 can be limited by the friction force to prevent the support sleeve 8 from sliding.

[0022] When the polishing machine is in use, the rubber sleeve 11 is abutted against the outside of the steel pipe, and the polishing machine body 1 is rotated around the axis of the fixed rod 7 so that the grinding disc 3 is abutted against the outside of the steel pipe. If it is found that the fitting part between the grinding disc 3 and the steel pipe is small, the U-shaped frame 5 can be driven to move by rotating the lead screw 63 while driving the polishing machine body 1 to move. Then, by continuing to rotate the polishing machine body 1, the size of the contact part between the grinding disc 3 and the steel pipe can be adjusted. After the contact part of the grinding disc 3 is adjusted, start the polishing machine body 1 to drive the grinding disc 3 to rotate, and the steel pipe is polished by the rotation of the grinding disc 3. When moving the position of the polishing machine body 1, the rubber sleeve 11 should always be abutted against the surface of the steel pipe. Through the damping bearings 10, the polishing machine body 1 can slowly move along with the rubber sleeve 11 outside the steel pipe. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to detail this application.

[0024] The above description is only a preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
