Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fastening structure of beveling machines, and in particular relates to a fixing device for pipe beveling machines. Background Technology
[0002] Before beveling the pipe sleeve end face, the pipe beveling machine needs to be installed on the outside of the pipe sleeve, allowing it to move along the pipe wall to bevele the pipe end face. When the mounting clamp of the pipe beveling machine is installed on the outside of the pipe, the top post on the side of the mounting clamp needs to be pressed tightly against the outer wall of the pipe to fix the mounting clamp to the outer wall of the pipe and to make the mounting clamp adaptable to pipes of various sizes. However, when the top post on the side wall of the mounting clamp protrudes at different lengths, the center of the mounting clamp will not coincide with the axis of the pipe cylinder. This will prevent the beveling machine from accurately beveling the pipe end face when moving on the mounting clamp, resulting in an uneven beveling of the pipe end face.
[0003] To address these issues, we provide a fixing device for pipe beveling machines. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for a pipe beveling machine. By clamping the first and second pipe clamps in the outer clamping assembly to the outside of the pipe, and setting the rotating mounting assembly at the upper end of the outer clamping assembly, the cutting mechanism of the beveling machine is set in the rotating mounting assembly, so that the outer clamping assembly can clamp pipes of different sizes. By sleeve the inner support assembly inside the pipe and fixing the lower end of the rotating mounting assembly to the upper end of the inner support assembly, the rotation axis of the rotating mounting assembly is made to coincide with the pipe cylinder axis, so that the rotation axis of the beveling machine in the rotating mounting assembly is made to coincide with the pipe cylinder axis, thus avoiding uneven beveling of the pipe due to installation misalignment of the beveling machine.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] A further feature of this invention is that the inner support assembly includes an inner threaded rod, a threaded support sleeve, and a set of support rods.

Detailed Implementation
[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Example 1
[0026] Please see Figure 1 and Figure 2This utility model relates to a fixing device for a pipe beveling machine, comprising an outer clamping assembly 1, an inner support assembly 2, and a rotating mounting assembly 3. The outer clamping assembly 1 includes a first pipe clamp 101 and a second pipe clamp 102. By clamping the first pipe clamp 101 and the second pipe clamp 102 in the outer clamping assembly 1 to the outside of the pipe, and setting the rotating mounting assembly 3 at the upper end of the outer clamping assembly 1, the cutting mechanism of the beveling machine is set in the rotating mounting assembly 3, so that the outer clamping assembly 1 can clamp pipes of different sizes. By sleeved the inner support assembly 2 inside the pipe and fixing the lower end of the rotating mounting assembly 3 at the upper end of the inner support assembly 2, the rotation axis of the rotating mounting assembly 3 is made to coincide with the pipe cylinder axis, thereby making the rotation axis of the beveling machine in the rotating mounting assembly 3 coincide with the pipe cylinder axis, avoiding uneven beveling of the pipe due to installation misalignment of the beveling machine.
[0027] Specifically, both the first pipe clamp 101 and the second pipe clamp 102 are horizontally open V-shaped structures. The open ends of the first pipe clamp 101 and the second pipe clamp 102 are opposite to each other. The first side handle 101a and the second side handle 102a are respectively fixed on the side of the first pipe clamp 101 and the second pipe clamp 102 away from the V-shaped open ends. A column is fixed on the upper end of the first side handle 101a and the second side handle 102a respectively.
[0028] Furthermore, the two sides of the first pipe clamp 101 are provided with clamping grooves 101b, and the two sides of the second pipe clamp 102 are slidably sleeved in the two clamping grooves 101b respectively. The inner support assembly 2 is disposed between the first pipe clamp 101 and the second pipe clamp 102.
[0029] Furthermore, the outer clamp assembly 1 also includes two pull rods 103. The two side edges of the second pipe clamp 102 extend and are fixedly provided with threaded ears 102b on the side away from the opening end. One end of each of the two pull rods 103 is rotatably installed on the end face of the two side edges of the first pipe clamp 101 and extends into the clamping groove 101b. The pull rods 103 are threaded into the threaded ears 102b. The end of the pull rod 103 away from the end of the transition with the end face of the first pipe clamp 101 is fixedly connected with a rotating end cap 103a. The first pipe clamp 101 and the second pipe clamp 102 are clamped on both sides of the pipe. By rotating the two pull rods 103, the first pipe clamp 101 and the second pipe clamp 102 clamp the pipe tightly.
[0030] The operation process in this embodiment is as follows:
[0031] The first pipe clamp 101 and the second pipe clamp 102 are fitted onto the outside of the pipe sleeve. The two pull rods 103 are rotated to clamp the pipe tightly. The inner support assembly 2 is rotated and fitted into the inside of the pipe. The lower end of the rotating installation assembly 3 is fixedly connected to the upper end of the inner support assembly 2. The upper end of the rotating installation assembly 3 is connected to the two columns at the upper ends of the first pipe clamp 101 and the second pipe clamp 102, so that the rotation axis of the rotating installation assembly 3 coincides with the pipe cylinder axis. The beveling machine is then installed into the rotating installation assembly 3, so that the rotation axis of the beveling machine in the circumferential motion coincides with the pipe cylinder axis.
[0032] Example 2
[0033] Please see Figures 1 to 5 Based on Embodiment 1, the rotating mounting assembly 3 includes a crossbeam 301, a mounting frame 302, and a sliding adapter sleeve 303. The inner support assembly 2 includes an inner threaded rod 201, a threaded support sleeve 202, and a set of wall support rods 203. The upper end of the crossbeam 301 is fixedly mounted on the upper ends of two columns, the sliding adapter sleeve 303 is slidably fitted onto the outside of the crossbeam 301, the mounting frame 302 is rotatably mounted on the lower end of the sliding adapter sleeve 303, and the lower end of the mounting frame 302 is fixedly mounted on the upper end of the inner support assembly 2. The connecting structure of the beveling machine is then installed inside the mounting frame 302, enabling the beveling machine to... When rotating, the mounting frame 302 is driven to rotate, while the rotation axis is restricted by the mounting frame 302, so that the rotation axis of the beveling machine coincides with the pipe cylinder axis; by rotating the threaded support sleeve 202 on the outside of the inner shaft threaded rod 201, a set of wall support rods 203 hinged at the lower end of the inner shaft threaded rod 201 is opened until the upper end of the wall support rod 203 is attached to the inner wall of the pipe, so that the rod axis of the inner shaft threaded rod 201 coincides with the pipe cylinder axis, and the rotation axis of the mounting frame 302 coincides with the pipe cylinder axis; wherein, the inner shaft threaded rod 201 only provides axial positioning and does not rotate with the mounting frame 302.
[0034] Specifically, column end sleeves 301a are slidably sleeved at both ends of the crossbeam 301. The two column end sleeves 301a are fixedly connected to the upper end faces of the columns on the first side handle 101a and the second side handle 102a, respectively. The sliding adapter sleeve 303 is slidably sleeved on the crossbeam 301. The mounting frame 302 is rotatably mounted on the lower end of the sliding adapter sleeve 303. The lower end of the mounting frame 302 is fixedly mounted on the upper end of the inner support assembly 2.
[0035] Furthermore, the upper ends of the sliding adapter sleeve 303 and the two column end sleeves 301a are all provided with threaded sleeves. A tightening stud 304 is screwed into the threaded sleeves at the upper ends of the sliding adapter sleeve 303 and the two column end sleeves 301a respectively. The lower end of the tightening stud 304 presses against the upper end plate of the crossbeam 301, so that the sliding adapter sleeve 303 and the two column end sleeves 301a are fixedly installed on the crossbeam 301.
[0036] Furthermore, a set of hinge seats 201a are fixedly arranged circumferentially on the lower outer wall of the inner shaft threaded rod 201. The lower ends of each wall support rod 203 are respectively hinged to each hinge seat 201a. The threaded support sleeve 202 is threadedly engaged on the outer side of the inner shaft threaded rod 201. The lower end of the mounting frame 302 is fixedly installed on the upper end face of the inner shaft threaded rod 201. The threaded support sleeve 202 is rotated downwards to open each wall support rod 203, so that the upper end of the wall support rod 203 is attached to the inner wall of the pipe.
[0037] Furthermore, a wall-adhering roller seat 203a is hinged to the upper end of the wall-supporting rod 203. The hinge rotation axis of the wall-adhering roller seat 203a and the wall-supporting rod 203 is perpendicular to the rod axis of the inner shaft threaded rod 201. A wall-adhering roller 203a-1 is rotatably mounted on the wall-adhering roller seat 203a. The roller axis of the wall-adhering roller 203a-1 is parallel to the rod axis of the inner shaft threaded rod 201. When the wall-supporting rod 203 is opened, the wall-adhering roller 203a-1 adheres to the inner wall of the pipe. When the beveling machine rotates, it drives the mounting frame 302 to rotate, and at the same time, it causes the inner shaft threaded rod 201 to rotate. The rolling contact between the wall-adhering roller 203a-1 and the inner wall of the pipe reduces friction.
[0038] The operation process in this embodiment is as follows:
[0039] The threaded support sleeve 202 is rotated downwards, causing it to open each of the wall support rods 203. When the wall support rods 203 are opened, the wall-adhering roller 203a-1 adheres to the inner wall of the pipe. When the beveling machine rotates, it drives the mounting frame 302 to rotate, which in turn causes the inner shaft threaded rod 201 to rotate. The rolling contact between the wall-adhering roller 203a-1 and the inner wall of the pipe reduces friction.
