Description

Technical Field

[0001] This utility model belongs to the field of pipe grinding technology, and in particular relates to a pipe grinding device. Background Technology

[0002] When grinding pipes and fittings, grinding equipment is needed to remove burrs from the surface and make the pipes smooth and flat. Currently, existing grinding equipment typically grinds the outer and inner circumference of the pipes separately, which requires improvement in grinding efficiency. Utility Model Content

[0003] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a pipe grinding device, which solves the problem that the outer circle and inner circle of the pipe are ground separately and sequentially when grinding the pipe, and the grinding efficiency needs to be improved.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pipe grinding device for grinding pipes, including a grinding bracket, on which two horizontally arranged outer grinding rollers are rotatably mounted. The two large outer grinding rollers are both connected to a driving component that drives their rotation. The rotation directions of the outer grinding rollers are the same. The pipe is placed above and between the two large outer grinding rollers. An n-shaped bracket is provided above and between the two large outer grinding rollers and can be raised and lowered. A round shaft is fixed on the n-shaped bracket. The axis of the round shaft is parallel to the axis of the large outer grinding rollers. Multiple small outer grinding rollers are rotatably mounted on the round shaft. An inner grinding roller is provided at one end of the pipe. The inner grinding roller is connected to a horizontal telescopic component that drives its horizontal movement. The inner grinding roller can be inserted into the pipe. A chip collection box is provided below the two large outer grinding rollers.

[0005] As a further improvement of this utility model, the driving component includes a motor, which is connected to one end of the outer grinding roller.

[0006] As a further improvement of this utility model, a limiting block is provided at both ends of the small outer grinding roller on the circular shaft.

[0007] As a further improvement of this utility model, the horizontal telescopic member is a first electric push rod.

[0008] As a further improvement of this utility model, the two ends of the round shaft are detachably connected to the n-shaped bracket, and the two ends of the round shaft are provided with threaded sections. The threaded sections at both ends of the round shaft extend out of the n-shaped bracket and are threadedly connected to the nuts.

[0009] As a further improvement of this utility model, the n-shaped bracket is connected to the fixed base through a second electric push rod that drives its lifting and lowering.

[0010] As a further improvement of this utility model, the grinding bracket includes a support, and the two ends of the large outer grinding roller are connected and mounted on the support through bearing seats.

[0011] Beneficial effects:

[0012] 1. By using two large, rotating outer grinding rollers and one horizontally movable inner grinding roller, the pipe is placed above and between the two large outer grinding rollers during grinding. The smaller outer grinding roller is adjusted up and down until its bottom contacts the outer wall of the pipe, thus limiting its movement. Then, the drive mechanism is activated, causing the two large outer grinding rollers to rotate. This rotation causes the pipe to rotate, and the large outer grinding rollers grind the outer wall of the pipe during rotation. Afterward, the inner grinding roller is inserted into the pipe, and it grinds the inner wall of the pipe during rotation. This allows for simultaneous grinding of both the inner and outer walls, greatly improving grinding efficiency. Furthermore, the large and small outer grinding rollers support and limit the movement of the pipe while simultaneously grinding it, resulting in a simple overall structure.

[0013] In addition, by providing a chip collection box, the iron filings that are ground off can be collected.

[0014] 2. By setting a limiting block at both ends of the small outer grinding roller on the round shaft, the small outer grinding roller can be limited. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0018] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0019] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0020] This utility model discloses a pipe grinding device. (Refer to...) Figure 1 A pipe grinding device is disclosed for grinding pipe fittings 1. It includes a grinding support 2, on which two horizontally arranged outer grinding rollers 3 are rotatably mounted. Both large outer grinding rollers 3 are connected to a driving component 4 that drives their rotation. The driving component 4 includes a motor, which is connected to one end of each outer grinding roller. The motor is fixed to the grinding support 2. The outer grinding rollers rotate in the same direction and at the same speed. The pipe fitting 1 is placed above and between the two large outer grinding rollers 3. An n-shaped support 5 is vertically movable above and between the two large outer grinding rollers 3. A circular shaft 6 is fixed on the n-shaped support 5, with its axis parallel to the axis of the large outer grinding rollers 3. Multiple small outer grinding rollers 7 are rotatably mounted on the circular shaft 6. A limiting block 10 is provided at both ends of each small outer grinding roller 7 on the circular shaft 6, thus limiting the movement of the small outer grinding rollers 7.

[0021] One end of the pipe fitting 1 is equipped with an inner grinding roller 8, which is connected to a horizontal telescopic component that drives its horizontal movement. The horizontal telescopic component is a first electric push rod 11, the body of which is fixed on the frame 18. The inner grinding roller 8 can be inserted into the pipe fitting 1 to grind the inner wall of the pipe fitting 1. A chip collection box 9 is provided below the two large outer grinding rollers 3 to collect the grinding chips.

[0022] More specifically, the two ends of the circular shaft 6 are detachably connected to the n-shaped bracket 5. The two ends of the circular shaft 6 are provided with threaded sections 12, which extend out of the n-shaped bracket 5 and are threadedly connected to nuts 13. The n-shaped bracket 5 is connected to the fixed base 15 via a second electric push rod 14 that drives its lifting and lowering. The grinding bracket 2 includes a support 17, and the two ends of the large outer grinding roller 3 are connected and mounted on the support 17 via bearing seats 16.

[0023] This invention features two large, rotating outer grinding rollers 3 and one horizontally movable inner grinding roller 8. During grinding, the pipe 1 is placed above the two large outer grinding rollers 3, and the small outer grinding roller 7 is adjusted vertically until its bottom contacts the outer wall of the pipe 1, thus limiting its movement. Then, the drive mechanism is activated, causing the two large outer grinding rollers 3 to rotate. This rotation of the large outer grinding rollers 3 causes the pipe 1 to rotate, grinding its outer wall. Subsequently, the inner grinding roller 8 is inserted into the pipe 1, grinding its inner wall as it rotates. This allows for simultaneous grinding of both the inner and outer walls of the pipe 1, significantly improving grinding efficiency. Furthermore, the large outer grinding rollers 3 and the small outer grinding roller 7 support and limit the movement of the pipe 1 while simultaneously completing the grinding process. The overall structure is simple.
