Description

Technical Field

[0001] The utility model relates to a pipe cutting auxiliary tool, in particular to a pipe cutting auxiliary support frame. Background Art

[0002] When a cutting machine is used to cut a round tube manually, since the cutting point of the cutting machine has a certain height, the round tube needs to be supported to a certain extent so that the tube is in a horizontal state to ensure that the cut of the round tube is flush during cutting. When a cutting machine is used to cut a round tube manually, square steel, angle steel, bricks and other objects are generally placed under the tube. On the one hand, the height of the round tube cannot be accurately adjusted to make the tube in a horizontal state. On the other hand, the round tube is prone to move left and right and deflect during the cutting process. Therefore, a support frame is urgently needed to support the round tube when the cutting machine is used to cut the round tube manually, to ensure the horizontality of the round tube and prevent it from shifting. Utility Model Content

[0003] The utility model aims to provide a pipe cutting auxiliary support frame to solve the problem that the horizontality of the round pipe cannot be guaranteed and the round pipe is prone to deviation when the round pipe is cut manually using a cutting machine.

[0004] The utility model is implemented as follows: a pipe cutting auxiliary support frame, including a base, a column is arranged on the base, the column is perpendicular to the base, an adjusting nut is threadedly connected to the column, and a lifting frame is sleeved on the column, the lifting frame is supported by the adjusting nut, and the height of the lifting frame is adjusted by the adjusting nut, support plates are respectively arranged at both ends of the lifting frame, a horizontal roller shaft is axially connected between the two support plates, and a centering groove is arranged around the axis of the roller shaft in the middle part.

[0005] As a further improvement of the auxiliary support frame for pipe cutting of the utility model, the axis of the roller is located on one side of the axis of the column, and the roller and the column are staggered with each other in the horizontal direction.

[0006] As a further improvement of the auxiliary support frame for pipe cutting of the utility model, the base is disc-shaped and the lifting frame is rectangular.

[0007] As a further improvement of the pipe cutting auxiliary support frame of the utility model, a hand wheel is arranged on the adjusting nut, and the center of the hand wheel coincides with the center of the adjusting nut.

[0008] As a further improvement of the auxiliary support frame for pipe cutting of the utility model, a contact plate is arranged on the top of the adjusting nut, and the diameter of the contact plate is larger than the diameter of the adjusting nut.

[0009] As a further improvement of the auxiliary support frame for pipe cutting of the utility model, a baffle extending upward is arranged on the top of the support plate.

[0010] As a further improvement of the pipe cutting auxiliary support frame of the utility model, both ends of the roller shaft are installed on the support plate through bearings.

[0011] The utility model is a pipe cutting auxiliary support frame, which is used to support the round pipe when the pipe is cut manually by a cutting machine. Multiple of the utility models can be set as needed, and the round pipe is supported by multiple pipe cutting auxiliary support frames at the same time, and the height of each pipe cutting auxiliary support frame is adjusted respectively, so that the height of the round pipe is adapted to the cutting machine and the horizontality of the round pipe is ensured. When the round pipe is placed on the roller, the lower part of the round pipe falls into the centering groove, so that the round pipe can be automatically centered and aligned, and the centering groove can limit the round pipe to the left and right, which can prevent the deviation of the round pipe to a certain extent.

[0012] The columns are staggered with the rollers in the horizontal direction, so that when adjusting the height, the columns extending upward will not immediately interfere with the round tubes on the rollers. The round tubes will only be affected when the tops of the columns exceed the bottoms of the round tubes, thus maximizing the height adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The structure of the utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5As shown, the utility model is a pipe cutting auxiliary support frame, including a base 1, a column 2, an adjusting nut 3, a lifting frame 4 and an axis roller 6. The base 1 is provided with a column 2, the column 2 is perpendicular to the base 1, the column 2 is threadedly connected with an adjusting nut 3, and the lifting frame 4 is sleeved on the column 2, the lifting frame 4 is supported by the adjusting nut 3, and the height of the lifting frame 4 is adjusted by the adjusting nut 3, support plates 5 are respectively provided at both ends of the lifting frame 4, a horizontal roller is axially connected between the two support plates 5, and a centering groove 7 is provided around the axis of the roller in the middle of the roller.

[0021] The column 2 is vertically fixed on the upper surface of the base 1 . The base 1 can be in a circular, rectangular or other shape, and the column 2 is generally located at the center of the base 1 .

[0022] The column 2 passes through the lifting frame 4 upward, and an external thread is provided on the surface of the column 2. The adjusting nut 3 is connected to the column 2 through the external thread. Since the adjusting nut 3 is located below the lifting frame 4, the height of the lifting frame 4 and the shaft roller 6 located on the lifting frame 4 can be adjusted by adjusting the nut 3. The shaft roller 6 can be located directly above the column 2. However, when adjusting the height, the column 2 extending upward may be blocked by the column 2, thereby limiting the height adjustment range.

[0023] In the pipe cutting auxiliary support frame of the utility model, a centering groove 7 is set in the middle of the shaft roller 6. In addition to contacting with the surface of the round tube 12 to automatically align the round tube 12, the centering groove 7 can also avoid the column 2 to a certain extent. The top of the column 2 can extend into the centering groove 7, thereby increasing the height adjustment range.

[0024] As a further improvement of the pipe cutting auxiliary support frame of the utility model, in order to further increase the height adjustment range, the axis of the roller is located on one side of the axis of the column 2, and the roller and the column 2 are staggered in the horizontal direction. In this way, when the lifting frame 4 descends, the column 2 extending upward will not be hindered by the shaft roller 6, as long as the top of the column 2 does not contact the round tube 12 placed on the shaft roller 6, thereby increasing the adjustable range of the height.

[0025] During use, after the pipe is placed on the utility model, the height of the pipe is approximately located on the cutting plane of the cutting machine, and generally only fine-tuning of the height of the pipe is required. Therefore, the above-mentioned improvement can basically meet the need for height adjustment.

[0026] The lifting frame 4 is generally a rectangular plate-shaped structure. The lifting frame 4 is in a horizontal state, and the column 2 is located on the left-right symmetrical center line of the lifting frame 4 .

[0027] The two support plates 5 on the support frame are located at two ends of the upper surface of the lifting frame 4 . The two support plates 5 are bilaterally symmetrical and perpendicular to the lifting frame 4 .

[0028] The shaft roller 6 is in a horizontal state, and both ends of the shaft roller 6 are respectively mounted on the support plates 5 at both ends through bearings 10, so that the shaft roller 6 can rotate freely.

[0029] The centering groove 7 is located in the middle of the shaft roller 6. The centering groove 7 is arc-shaped or V-shaped. When the round tube 12 is placed on the shaft roller 6, under the action of its own weight, the round tube 12 contacts the centering groove 7 and has two contact points. The two contact points are symmetrical about the center of the length direction of the shaft roller 6, thereby realizing automatic centering and alignment of the round tube 12.

[0030] The centering groove 7 can limit the movement of the round tube 12 . In order to prevent the round tube 12 from escaping from the centering groove 7 and falling along the shaft roller 6 , a baffle 11 extending upward is provided on the upper part of the support plate 5 .

[0031] For ease of operation, a handwheel 8 is provided on the adjusting nut 3, and the center of the handwheel 8 coincides with the center of the adjusting nut 3. By rotating the handwheel 8, the adjusting nut 3 can be driven to rotate, thereby achieving height adjustment. The diameter of the outer ring of the handwheel 8 is large, and the operator can operate it conveniently without being affected by the lifting frame 4.

[0032] At the same time, a contact plate 9 is arranged on the top of the adjusting nut 3. The diameter of the contact plate 9 is larger than the diameter of the adjusting nut 3. The contact plate 9 directly has a large contact area with the lower surface of the lifting frame 4, which can ensure the stability of the support between the adjusting nut 3 and the lifting frame 4.

[0033] When in use, several of the utility models are arranged along a straight line, and then the round tube 12 to be cut is placed on the shaft roller 6 of the utility model, the cutter is placed in the forward direction of the round tube 12, and the round tube 12 is sent between the cutter blade and the base 1, and each utility model is adjusted so that the round tube 12 is in a horizontal state and the height is just that the lower part of the round tube 12 contacts the cutter base 1, the length of the extended round tube 12 is adjusted, the cutter is started for cutting, and the round tube 12 is moved forward as needed, so as to continuously cut to obtain several sections of the round tube 12 of the required length.

[0034] The utility model has a simple structure and is easy to operate. It can adjust the height and levelness of the round tube 12. When the round tube 12 is placed on the roller, the lower part of the round tube 12 falls into the centering groove 7, so that the round tube 12 can be automatically centered and aligned, and the centering groove 7 can limit the round tube 12 to the left and right, which can prevent the round tube 12 from deviating to a certain extent, thereby improving the cutting stability and cutting quality, and ensuring the flushness of the cutting surface. The utility model can adapt to the situation where the ground height is uneven at the operation site, and the levelness adjustment of a long round tube 12 can be achieved through a plurality of the utility models.
