Description

Technical Field

[0001] This utility model relates to the technical field of pipe grinding machines, specifically a pipe beveling grinding machine. Background Technology

[0002] Pipe grinding machines are tools specifically designed for beveling the front face of pipes or flat plates. They aim to solve problems such as non-standard angles, rough bevels, and high noise levels in traditional processes such as flame cutting and polishing.

[0003] The patent with publication number CN214517971U discloses a simple pipe beveling machine, which includes a first fixing mechanism, a second fixing mechanism, a driving mechanism, and a hole opener; the first fixing mechanism includes a first base and a fixing seat for fixing the pipe. The device has a simple structure, is easy to operate, has a low cost, greatly saves the time of manual beveling, and improves work efficiency.

[0004] However, the existing device directly clamps and limits the pipe using a limiting ring and locking mechanism, and then grinds the pipe bevel using an opening device. However, the bevel width of the beveling machine must be controlled by the operator, that is, the operator must manually move the opening device continuously towards the pipe and constantly observe the degree of bevel opening. The operation is cumbersome. Therefore, a pipe beveling grinding machine is proposed to solve the problem that the existing beveling machine cannot achieve precise beveling according to the beveling requirements.

[0025] Furthermore, the T-block 10 is fixedly connected to the adjusting seat 6, the bottom of the hydraulic telescopic rod 8 is fixedly connected to the bottom of the inner cavity of the adjusting seat 6, the two sides of the high-strength spring 13 are respectively connected to the adjusting seat 6 and the L-shaped adjusting seat 5, the left side of the scale 14 is fixedly connected to the adjusting seat 6, the scale 14 passes through the L-shaped adjusting seat 5 and the two are slidably connected.

[0026] Furthermore, when the high-strength spring 13 is in its normal state, the zero mark of the scale 14 is aligned with the right boundary of the L-shaped adjustment seat 5, the output shaft of the servo motor 12 passes through the adjustment groove 4 and is fixedly connected to the screw 11, and the screw 11 passes through the L-shaped adjustment seat 5 and is threaded.

[0027] Furthermore, the clamping mechanism 7 includes clamping plates 701 symmetrically arranged in the inner cavity of the placement seat 15, and the opposite surfaces of the clamping plates 701 are symmetrical and fixedly connected with arc-shaped clamping blocks 702.

After the pipe is placed in the placement seat 15 and the right side of the pipe is in contact with the cavity wall of the placement seat 15, the electric push rods 703 are turned on, which drives the clamping plate 701 to move towards the pipe. Then, in conjunction with the arc-shaped clamping block 702, the pipe is clamped and limited according to its size.

[0031] Working principle: When using this pipe beveling grinding machine, after adjusting the opening mechanism 3 according to the pipe size, the round pipe is placed in the placement seat 15 and limited. Then, the hydraulic telescopic rod 8 in the adjusting seat 6 drives the pipe to move up to the appropriate position.

With the help of the T-block 10 in the T-slot 9, the adjusting seat 6 moves to the right to compress the high-strength spring 13 and makes the scale 14 equal to the beveling width. At this time, when the opening mechanism 3 beveles the pipe, the elastic force of the high-strength spring 13 achieves the purpose of precise beveling, which solves the problem that existing beveling machines cannot achieve precise beveling grinding according to beveling requirements.
