Description

Technical Field

[0001] The utility model relates to the technical field of grinding block mechanisms for grinding the inner wall of a pipe body, in particular to a grinding block mechanism for grinding the inner wall of a pipe body. Background Art

[0002] Announcement No. CN207771459U discloses a grinding block mechanism for grinding the inner wall of a pipe body, comprising an outer shell, an inner wall of the outer shell fixedly connected to a threaded rod, an inner sleeve inserted into the outer shell, an inner wall of the inner sleeve fixedly connected to an internally threaded column, the internally threaded column being threadedly connected to the threaded rod, a through hole being opened on the surface of the outer shell, a connecting rod being inserted into the inner wall of the through hole, and one end of the connecting rod being fixedly connected to a wedge block. The utility model rotates the inner sleeve by rotating the knob. When the inner sleeve rotates, the connection between the internally threaded column and the threaded rod causes the inner sleeve to expand and contract within the outer sleeve. The wedge block, under the force of the spring, always adheres to the surface of the inner sleeve. As the inner sleeve continues to move, the diameter of the contact area between the inner sleeve and the wedge block also changes continuously, causing the connecting rod to expand and contract. By adjusting the connecting rod expansion and contraction, the diameter of the grinding block mechanism is adjusted, so that the grinding block can perfectly fit the inner wall of the pipe body, making it easier to grind the inner wall of the pipe body. In traditional pipe inner wall grinding technology, manual or semi-automated equipment is usually used to control the position and rotation of the grinding tool. This design method lacks automated precision guidance and movement control, resulting in low grinding accuracy and prone to deviation, resulting in uneven grinding of the inner wall surface, affecting the processing quality. Traditional methods lack a synchronized rotation mechanism during the grinding process, making it difficult to achieve full-scale grinding. Multiple adjustments and repeated operations are often required to cover all areas of the inner wall. This not only increases the workload but also reduces overall efficiency, and needs improvement.

[0007] Preferably, the gear is meshed with the gear ring, and the gear is rotationally connected to the slider. Here, the motor B can smoothly drive the rotating ring to rotate through the gear and the gear ring.

[0008] Preferably, a clamping block is fixedly mounted on the side of the slider, which is internally slidably connected to a limit block. A brush is fixedly mounted on the surface of the limit block. The limit block is internally slidably connected to a limit rod. A push plate is fixedly mounted on one end of the limit rod. A spring B is fixedly mounted on the side of the push plate. Here, the limit block and brush can smoothly clean waste and debris inside the pipe, avoiding the need for cleaning after grinding is completed, thereby improving overall efficiency.

[0009] Preferably, the limit rod is slidably connected to the clamping block, and one end of the spring B is fixedly connected to the limit block. Here, the spring B can automatically slide the limit rod from the inside of the limit block to the inside of the clamping block, so that the limit block and the brush are clamped and fixed.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] 1. In this utility model, the slider moves automatically by coordinating with the screw and guide rod, and the rotating ring rotates during the slider's movement, thereby achieving comprehensive grinding of the pipe inner wall by the grinding block. This design enables the grinding block mechanism to automatically and comprehensively cover the inner wall surface, ensuring a uniform grinding effect, effectively improving work efficiency, reducing the need for human intervention, and enhancing the efficiency of precision grinding.

[0012] 2. In the utility model, by setting the card block, the limit block, the brush, the limit rod, the push plate and the spring B, it is possible to automatically clean up some debris during the grinding process, so that the inner wall of the pipe can be automatically ground while the waste can be cleaned, thereby improving the efficiency of waste treatment.

[0024] Example 2

[0025] See also Figure 1-5The side of the slider 5 is fixedly installed with a block 13, the internal sliding connection of the block 13 is limited to the block 14, and the surface of the limit block 14 is fixedly installed with a brush 15, the internal sliding connection of the limit block 14 is limited to the rod 16, and one end of the limit rod 16 is fixedly installed with a push plate 17, and the side of the push plate 17 is fixedly installed with a spring B18.
