AI Technical Summary
Existing CNC flame cutting machines have difficulty adjusting the height and position of the torch when the plate is uneven or not on the same horizontal plane as the track, resulting in poor cutting quality. In addition, the lack of limiters on the lifting rod makes it inconvenient to use and causes position changes.
A mechanical automatic height adjustment flame cutting torch was designed, which adopts a gear and rack structure and a limiting block. The movement of the lifting rod is restricted by the meshing of the gear and rack to prevent it from sliding down under the action of gravity and to prevent the torch position from changing.
It enables stable adjustment of the cutting torch height and position, ensuring cutting quality, simplifying the plate feeding process, and avoiding arbitrary changes in the cutting torch position.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flame cutting machine technology, and in particular to a mechanical automatic height adjustment flame cutting torch. Background Technology
[0002] During operation, CNC flame cutting machines often experience changes in the distance between the nozzle and the material due to unevenness of the sheet metal or the sheet metal and the track not being on the same horizontal plane. This makes it impossible to manually adjust the height and position of the torch at any time, which can easily lead to defects such as missing material at the bevel and unevenness, affecting the cutting quality, ensuring the quality of the bevel, and affecting the next process. In severe cases, it can even burn out the nozzle.
[0003] CN 215999054 U discloses a mechanical automatic height adjustment CNC flame cutting torch and a CNC flame cutting machine, including a lifting rod, clamping rollers, clamping blocks, a crossbeam, casters, and a cutting torch; the cutting torch and clamping blocks are fixed on the crossbeam, the clamping rollers are fixed above the crossbeam, the lifting rod passes through the clamping rollers and clamping blocks from top to bottom and is connected to the casters, and the lifting rod is fixed together with the clamping blocks and the crossbeam, and the casters can slide freely up and down between the clamping rollers under the action of external force, carrying the lifting rod and the crossbeam.
[0004] During operation, the torch height adjustment device drives the torch to move synchronously. When the surface of the sheet metal is uneven, the lifting rod of the torch height adjustment device moves up and down, simultaneously driving the torch up and down, so that the change in torch height matches the change in sheet metal unevenness. However, the lifting rod of the aforementioned flame cutting torch lacks a limit switch. When no sheet metal is placed on the cutting machine, the lifting rod will fall to its lowest point under gravity. This means that the lifting rod needs to be raised again each time a sheet metal is placed, which is inconvenient to use. Furthermore, the lifting rod can rotate freely between the clamping rollers, which can easily change the position of the torch during cutting, affecting the cutting quality. Utility Model Content
[0005] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a mechanical automatic height adjustment flame cutting torch.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a mechanical automatic height-adjustable flame cutting torch, including a crossbeam, on which several sets of cutting torches are installed, universal wheels are fixedly installed at the bottom of the crossbeam, a lifting rod is fixedly installed at the top of the crossbeam, a support frame is provided around the lifting rod, several sets of first clamping wheels are movably installed on the front side of the support frame, several sets of second clamping wheels are rotatably installed on the rear side of the support frame, gears are fitted on the second clamping wheels, a rack is embedded in the side wall of the lifting rod, and a limit block is movably installed on the side of the support frame near the second clamping wheels.
[0007] Furthermore, the support frame includes two sets of side uprights, which are located on the left and right sides of the lifting rod, respectively, and connecting plates are fixedly installed on the rear side walls of the two sets of side uprights.

The limiting block restricts the rotation of the gear, thereby preventing the lifting rod from sliding down under the action of gravity, so as to facilitate the subsequent loading and processing of the plate. In addition, the rack is installed on the lifting rod in an embedded manner. The gear can prevent the lifting rod from rotating freely, thereby preventing the position of the cutting torch from changing during cutting, and thus ensuring the cutting quality.

[0024] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0025] according to Figure 1-6 As shown, a mechanical automatic height-adjustable flame cutting torch includes a crossbeam 1, on which several sets of torches 2 are mounted. A caster wheel 3 is fixedly mounted at the bottom of the crossbeam 1, and a lifting rod 4 is fixedly mounted at the top of the crossbeam 1. A support frame is provided around the lifting rod 4. Several sets of first clamping wheels 8 are movably mounted on the front side of the support frame, and several sets of second clamping wheels 13 are rotatably mounted on the rear side of the support frame via bearings. Gears 134 are fitted onto the second clamping wheels 13. A rack 5 is embedded in the side wall of the lifting rod 4, and a limit block 15 is movably mounted on the side of the support frame near the second clamping wheels 13.
[0026] In this embodiment, the support frame includes two sets of side plates 6, which are located on the left and right sides of the lifting rod 4, respectively. A connecting plate 7 is fixedly installed on the rear side wall of the two sets of side plates 6, and the side plates 6 on the left and right sides of the lifting rod 4 are connected to each other through the connecting plate 7. A mounting seat 16 is fixedly installed on the outer wall of the two sets of side plates 6, and the support frame is fixedly installed on the flame cutting machine through the mounting seat 16.
[0027] In this embodiment, the side plate 6 has an "I" shaped structure. The upper and lower ends of the front side wall of the side plate 6 are provided with sliding grooves 61. Each set of sliding grooves 61 is provided with a first clamping wheel 8. The side wall of the first clamping wheel 8 is provided with a first arc-shaped groove 81 that matches the lifting rod 4. The left and right sides of the first clamping wheel 8 are rotatably mounted with sliding seats 9. The two sets of sliding seats 9 are slidably mounted in the sliding grooves 61 respectively. The front ends of the two sets of sliding seats 9 are fixedly mounted with connecting frames 10. The front ends of the sliding grooves 61 are fixedly mounted with baffles 11. Fastening bolts 12 are installed on the baffles 11 by threaded engagement. By tightening the fastening bolts 12, the ends of the fastening bolts 12 abut against the connecting frames 10, thereby pushing the first clamping wheel 8 to fit tightly against the lifting rod 4.
[0028] In this embodiment, the second clamping wheel 13 includes two sets of wheel discs 131, which are symmetrically arranged. The side wall of each wheel disc 131 is provided with a second arc-shaped groove 1311 that matches the lifting rod 4. A connecting shaft 132 is installed between the two sets of wheel discs 131 by key engagement. The gear 134 is installed on the connecting shaft 132 by key engagement. The wheel discs 131 and the gear 134 are connected to each other through the connecting shaft 132. When the gear 134 rotates, it drives the wheel discs 131 to rotate synchronously through the connecting shaft 132.
[0029] In this embodiment, a threaded through hole 1321 is provided at the center of the connecting shaft 132. The wheel 131 and the connecting shaft 132 are fixedly connected by a connecting bolt 133. The connecting bolt 133 clamps the two sets of wheel 131 toward the middle of the connecting shaft 132, so that the side wall of the gear 134 is in close contact with the wheel 131.
[0030] In this embodiment, a cylinder 14 is fixedly installed on the bottom end of the connecting plate 7 away from the second clamping wheel 13. The power output end of the cylinder 14 passes through the connecting plate 7 and is fixedly connected to the limiting block 15. The limiting block 15 is provided with a toothed block that matches the gear 134. The cylinder 14 drives the limiting block 15 to move closer to the bottommost second clamping wheel 13 and makes the limiting block 15 mesh with the gear 134, thereby limiting the rotation of the second clamping wheel 13 through the limiting block 15, and thus limiting the movement of the lifting rod 4.
[0031] When this utility model is in use, after the plate cutting is completed and the material is unloaded, the push rod of the cylinder 14 is pushed out, so that the limiting block 15 is engaged with the gear 134 on the bottommost second clamping wheel 13. The limiting block 15 restricts the rotation of the gear 134. With the cooperation of the rack 5 and the gear 134, the lifting rod 4 is prevented from sliding down under the action of gravity, so as to facilitate the subsequent loading and processing of the plate. The rack 5 is installed on the lifting rod 4 in an embedded manner, and the gear 134 is inserted into the groove on the side wall of the lifting rod 4. The gear 134 prevents the lifting rod 4 from rotating freely, thereby preventing the position of the cutting torch from changing during cutting, and thus ensuring the cutting quality.

The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
