Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe inner ring processing, in particular to a grinding device for steel pipe inner ring processing. Background Art

[0002] At present, during the processing of steel pipes, the steel pipes need to be polished. When the inner ring of the steel pipe is polished, the polishing debris is easily adhered to the inner wall of the steel pipe, so that the inner ring of the steel pipe needs to be cleaned after polishing, thereby reducing the practicality of the polishing device.

[0003] Existing Chinese patent CN207724092U discloses a grinding device for processing the inner ring of a steel pipe. The grinding device for processing the inner ring of a steel pipe is used in conjunction with a steel wire rope, a servo motor and an electric motor. When the servo motor drives the steel wire rope for transmission, the electric motor can drive the grinding head to move while grinding the inner ring of the steel pipe, and at the same time drive the brush plate to brush the inner wall of the steel pipe back and forth;

[0004] However, because the right end of the electric motor is connected by a steel wire rope, when the electric motor drives the rotating shaft to rotate, and then drives the grinding structure and brush plate structure to work, the friction between the inner wall of the steel pipe and the grinding head and brush plate will react on the rotating shaft, and then act on the electric motor, causing the electric motor itself to twist, and then causing the steel wire rope itself to twist, making the overall structure unstable and posing a safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide a grinding device for processing the inner ring of a steel pipe, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a grinding device for processing the inner ring of a steel pipe, comprising a base plate, a mounting frame fixedly mounted on the top of the base plate, a conveying component fixedly mounted on the top of the base plate, a lifting component fixedly mounted on the top of the mounting frame, and a grinding component fixedly mounted on the lifting end of the lifting component;

An adjusting slot 405 is provided at the center of the adjusting plate 404. A fixing bolt 406 is fixedly installed on the side of the mounting plate 403. The fixing bolt 406 passes through the adjusting slot 405. The adjusting slot 405 is strip-shaped. A nut is threaded on the fixing bolt 406, and the nut is tightly pressed on the adjusting plate 404. There are two mounting plates 403. A cleaning brush 407 is fixedly installed on the end of the adjusting plate 404 on the left mounting plate 403, and a grinding head 408 is fixedly installed on the end of the adjusting plate 404 on the right mounting plate 403. The mounting plate 403 is close to the left end of the rotating shaft 402, and the left end of the rotating shaft 402 is aligned with the left end of the base plate 1. The lifting component 3 is provided for adjusting the grinding up and down. The height of component 4 makes the central axis of the mounting plate 403 in the grinding component 4 coincide with the central axis of the steel pipe. A conveying component 5 is provided for conveying the steel pipe. The motor 401 drives the rotating shaft 402 to rotate, thereby driving the mounting plate 403 to rotate. The rotation of the mounting plate 403 drives the adjusting plate 404 to rotate, thereby driving the cleaning brush 407 and the grinding head 408 to rotate. The grinding head 408 grinds the inner wall of the steel pipe, and the cleaning brush 407 cleans the debris generated by grinding. During the grinding process, the steel pipe is conveyed by the conveying component 5, and the position of the grinding component 4 remains unchanged. Therefore, a rigid structure can be used to fix the grinding component 4, and the adjusting plate 404 is installed with the fixing bolt 406 and the adjusting slot 405, so that the distance between the adjusting plate 404 and the center of the mounting plate 403 is adjustable. Then, when grinding steel pipes with different inner diameters, the position of the adjusting plate 404 can be adjusted so that the cleaning brush 407 and the grinding head 408 can contact the inner wall of the steel pipe.

[0024] The lifting component 3 includes an electric telescopic rod 301, which is fixedly mounted on the top of the mounting frame 2.

The outer wall sliding sleeve of the guide rod 302 is provided with a guide sleeve 303. The guide sleeve 303 is fixedly mounted on the inner wall of the mounting frame 2. The lifting frame 304 is the lifting end of the lifting component 3. The motor 1 401 is fixedly mounted on the lifting frame 304. The electric telescopic rod 301 drives the lifting frame 304 to move up and down, thereby driving the motor 1 401 to move up and down. The lifting of the motor 1 401 drives the rotating shaft 402 to move up and down, thereby driving the mounting plate 403 to move up and down, and adjusting the height of the mounting plate 403. The guide rod 302 and the guide sleeve 303 are provided to guide the lifting frame 304 to reduce the radial force acting on the extended end of the electric telescopic rod 301.

[0025] The conveying component 5 includes a fixed seat 501 and an inclined plate 504. The fixed seat 501 and the inclined plate 504 are fixedly installed on the top of the bottom plate 1. There are two inclined plates 504, and they are symmetrically distributed front and back about the center of the fixed seat 501. The inner side of the fixed seat 501 is rotatably connected to the conveying roller 503 through a bearing. The outer wall of the fixed seat 501 is fixedly installed with a motor 502. The output end of the motor 502 is fixedly connected to the central axis of the conveying roller 503. The inner wall of the inclined plate 504 is threadedly connected with a screw rod 507, and the screw rod 507 is oriented toward the fixed seat 501. One end is rotatably connected to the second fixing seat 505 through a bearing, and the inner side of the second fixing seat 505 is rotatably connected to the pressing roller 506 through a bearing. The outer wall of the second fixing seat 505 is fixedly installed with a sliding rod 508, and the sliding rod 508 movably penetrates the outer wall of the inclined plate 504. The position of the second fixing seat 505 is changed by rotating the screw rod 507, thereby driving the pressing roller 506 to move, so that the pressing roller 506 presses the steel pipe on the conveying roller 503, and the conveying roller 503 is driven to rotate by the second motor 502. The friction between the conveying roller 503 and the steel pipe drives the steel pipe to move;

[0026] There are multiple adjustment plates 404 on the mounting plate 403, and the adjustment plates 404 are distributed in a circular array on the mounting plate 403, which are used to set multiple cleaning brushes 407 and grinding heads 408 to improve the processing efficiency of the steel pipe;

[0027] The lifting frame 304 is an L-shaped aluminum alloy frame with low weight and sufficient strength. The right end of the lifting frame 304 is aligned with the right end of the bottom plate 1, so that there is enough space between the motor 401 and the left end of the rotating shaft 402;

[0028] There are two groups of fixed seats 1 501 and fixed seats 2 505, wherein the two groups of fixed seats 2 505 are fixedly connected by a connecting plate 6, which is used to set two groups of conveying rollers 503 and clamping rollers 506 to increase the contact area during the steel pipe conveying process, thereby improving the stability of steel pipe conveying. The connecting plate 6 is set to connect the two groups of fixed seats 2 505, so that when the position of one group of fixed seats 2 505 is adjusted, the other group can be adjusted synchronously.

[0029] Working principle: When in use, adjust the position of the adjustment plate 404 according to the inner diameter of the steel pipe, and turn on the electric telescopic rod 301 to drive the lifting frame 304 to move up and down, thereby driving the motor 1 401 to move up and down, and the lifting of the motor 1 401 drives the shaft 402 to move up and down, thereby driving the installation plate 403 to move up and down, and adjust the height of the installation plate 403 so that the central axis of the installation plate 403 coincides with the central axis of the steel pipe, and move the steel pipe horizontally so that it falls on the conveying roller 503, and rotate the screw rod 507 to adjust the position of the fixing seat 2 505, thereby causing the pressing roller 506 to push the steel pipe. The steel pipe is pressed onto the conveying roller 503. At this time, the cleaning brush 407 and the grinding head 408 are extended into the steel pipe. The motor 1 401 is turned on to drive the rotating shaft 402 to rotate, and then the mounting plate 403 is driven to rotate. The rotation of the mounting plate 403 drives the adjustment plate 404 to rotate, and then the cleaning brush 407 and the grinding head 408 are driven to rotate. The grinding head 408 grinds the inner wall of the steel pipe, and the cleaning brush 407 cleans the debris generated by grinding. The motor 2 502 is turned on to drive the conveying roller 503 to rotate. The friction between the conveying roller 503 and the steel pipe drives the steel pipe to move to the right.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
