Description

Technical Field

[0001] This utility model relates to the technical field of flame cutting devices, specifically a flame cutting device that is easy to adjust in distance. Background Technology

[0002] Flame cutting is a common method for rough machining of steel plates. Flame cutting, also known as gas cutting, traditionally used acetylene, later propane, and now natural gas cutting has emerged. Due to its abundant reserves, low price, and pollution-free characteristics, natural gas has become the preferred choice for flame cutting. Natural gas flame cutting typically involves adding natural gas additives to generate a new type of flame cutting gas. Using this gas for flame cutting can improve cutting results, increase cutting efficiency, and reduce cutting costs.

[0003] According to CN217071078U, a high-precision flame cutting device is disclosed. This technology discloses a technical solution such as "a high-precision flame cutting device, including a storage groove, a frame above the storage groove, a movable groove inside the frame, a movable block movably installed inside the movable groove, a flame cutting machine fixedly installed at the bottom of the movable block, and a spray head movably installed at the bottom of the flame cutting machine". It has the technical effect of "the ball bearing at the bottom of the mounting plate can contact the top of the steel plate. When the surface of the steel plate is uneven, the limiting spring at the bottom of the movable rod ensures that the ball bearing is always in contact with the surface of the steel plate. Since one end of the movable rod is connected to the movable plate, the relative distance between the movable plate and the surface of the steel plate can be kept constant, that is, the distance between the spray head and the surface of the steel plate remains constant".

[0004] Existing flame cutting heads may have relatively fixed fixing methods, lacking sufficient adjustment space or adjustment mechanisms. Some may allow users to change the angle of the cutting head by turning adjustment knobs or moving levers using tools. Since the appropriate tools are required for each operation, this increases the complexity and tediousness of the operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flame cutting device that facilitates distance adjustment. It features the ability to adjust the torch angle simply by pressing the pin, and to disassemble and assemble the torch simply by rotating the cylinder cover.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame cutting device with adjustable distance, comprising a machine tool and a cutting torch, wherein the machine tool is equipped with an adjustment mechanism for adjusting the position of the cutting torch, the adjustment mechanism comprising:

[0007] The main components include a fixed base mounted on the machine tool, a bracket rotatably mounted on the fixed base, a mounting bracket mounted on the bracket, and a mounting seat mounted at the front end of the mounting bracket.

[0008] The actuator includes a rear shell fixed inside the front end of the mounting bracket, a front shell rotatably mounted on the rear shell via a pivot, several equally spaced grooves on the inner wall of the front shell, a slidingly mounted pin through the interior of the rear shell, a protrusion fixed at the front end of the pin and cooperating with the groove, and a spring sleeved on one end of the pin.

[0009] A fixing component, which is set on the main component and used to fix the cutting torch.

[0010] Preferably, the fixing component includes a cylindrical shell fixed inside the front end of the mounting base, a rubber head installed inside the cylindrical shell, a clamping sleeve installed at the lower end inside the cylindrical shell, and a cylindrical cover threadedly installed at the lower end of the cylindrical shell.

[0011] Preferably, the fixing component further includes a plurality of slots evenly distributed on the rubber head.

[0012] Preferably, the actuating component further includes a slot formed inside the pin, and the rotating shaft passes through the slot.

[0013] Preferably, the main component further includes a first bolt installed between the fixed seat and the bracket, and the fixed seat and the bracket are fixed together by the first bolt.

[0014] Preferably, the main component further includes waist-shaped holes formed on both sides inside the bracket, and a second bolt for mounting between the bracket and the mounting frame.

[0015] Beneficial effects

[0016] This invention provides a flame cutting device with easily adjustable distance. Compared with the prior art, it has the following advantages:

[0017] (1) By pressing the pin, the protrusion is disengaged from the groove, thereby releasing the fixation between the rear shell and the rotating shaft. This allows the rotating mounting base to rotate and adjust the angle of the cutting torch fixed on the fixing assembly. Then, the pressed pin is released and the spring return pressure causes the protrusion to be inserted into the corresponding groove, fixing the rear shell and the rotating shaft. This also fixes the angle of the cutting torch fixed on the fixing assembly through the mounting base, so that the angle of the cutting torch can be adjusted simply by pressing the pin.

[0018] (2) When the cutting torch is inserted into the cylinder shell and passes through the rubber head, the clamping sleeve and the cylinder cover, rotate and tighten the cylinder cover to push the clamping sleeve, so that the clamping sleeve squeezes the groove and shrinks, thereby fixing the cutting torch in the middle, so that the cutting torch can be disassembled and assembled by simply rotating the cylinder cover.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a flame cutting device with easily adjustable distance: a flame cutting device with easily adjustable distance, comprising a machine tool 1 and a cutting torch 3, characterized in that: the machine tool 1 is provided with an adjustment mechanism 2 for adjusting the position of the cutting torch 3, the adjustment mechanism 2 comprising:

[0027] The main component 21 includes a fixed base 211 mounted on the machine tool 1, a bracket 212 rotatably mounted on the fixed base 211, a mounting bracket 213 mounted on the bracket 212, and a mounting seat 214 mounted at the front end of the mounting bracket 213.

[0028] The execution component 22 includes a rear shell 221 fixed inside the front end of the mounting bracket 213, a front shell 223 rotatably mounted on the rear shell 221 via a pivot 222, a plurality of equally distributed grooves 224 on the inner wall of the front shell 223, a pin 225 slidably mounted through the interior of the rear shell 221, a protrusion 226 fixed at the front end of the pin 225 and cooperating with the grooves 224, and a spring 227 sleeved on one end of the pin 225;

[0029] The fixing component 23 is disposed on the main component 21 and is used to fix the cutting torch 3.

[0030] In this embodiment, pressing the pin 225 causes the protrusion 226 to disengage from the groove 224, thereby releasing the fixation between the rear shell 221 and the rotating shaft 222. This allows the rotatable mounting base 214 to rotate and adjust the angle of the cutting torch 3 fixed on the fixing assembly 23. Then, releasing the pressed pin 225 and using the pressure of the spring 227 to push the protrusion 226 into the corresponding groove 224, fixes the rear shell 221 and the rotating shaft 222. This fixes the angle of the cutting torch 3 fixed on the fixing assembly 23 through the mounting base 214, so that the angle of the cutting torch 3 can be adjusted simply by pressing the pin 225.

[0031] Specifically, the fixing component 23 includes a cylindrical shell 231 fixed inside the front end of the mounting base 214, a rubber head 232 installed inside the cylindrical shell 231, a clamping sleeve 234 installed at the lower end inside the cylindrical shell 231, and a cylindrical cover 235 threadedly installed at the lower end of the cylindrical shell 231.

[0032] In this embodiment, after the cutting torch 3 is inserted into the cylinder shell 231 and passes through the rubber head 232, the clamping sleeve 234 and the cylinder cover 235, the cylinder cover 235 is rotated and tightened to push the clamping sleeve 234, so that the clamping sleeve 234 squeezes the groove 233 to shrink, thereby fixing the cutting torch 3 in the middle, so that the cutting torch 3 can be disassembled and assembled by simply rotating the cylinder cover 235.

[0033] Specifically, the fixing component 23 also includes a number of slots 233 evenly distributed on the rubber head 232.

[0034] In this embodiment, when the rubber head 232 is squeezed by the clamping sleeve 234, it has a certain space to shrink towards the center through the groove 233.

[0035] Specifically, the actuator 22 also includes a slot 228 formed inside the pin 225, and the rotating shaft 222 passes through the slot 228.

[0036] In this embodiment, the pin 225 is moved through the slot 228 to avoid motion interference with the rotating shaft 222.

[0037] Specifically, the main body component 21 also includes a first bolt 215 installed between the fixed seat 211 and the bracket 212, and the fixed seat 211 and the bracket 212 are fixed together by the first bolt 215.

[0038] In this embodiment, the angle between the fixed base 211 and the bracket 212 can be adjusted by the first bolt 215, thereby adjusting the angle between the cutting torch 3 and the machine tool 1.

[0039] Specifically, the main component 21 also includes waist-shaped holes 216 opened on both sides inside the bracket 212, and a second bolt 217 installed between the bracket 212 and the mounting bracket 213.

[0040] In this embodiment, the length between the bracket 212 and the mounting bracket 213 is adjusted and fixed by using the waist-shaped hole 216 and the second bolt 217, thereby adjusting the distance between the cutting torch 3 and the machine tool 1 and avoiding interference between the cutting torch 3 and the equipment next to the machine tool 1 during the cutting process under special circumstances.

[0041] The working principle and usage process of this utility model are as follows: First, the cutting torch 3 is inserted into the cylinder shell 231 and passes through the rubber head 232, the clamping sleeve 234, and the cylinder cover 235. Then, the cylinder cover 235 is rotated and tightened to push the clamping sleeve 234, causing the clamping sleeve 234 to compress the groove 233 and shrink, thereby fixing the cutting torch 3 in the middle. Then, the angle between the fixing seat 211 and the bracket 212 can be adjusted by the first bolt 215, thereby adjusting the angle between the cutting torch 3 and the machine tool 1. Then, the length between the bracket 212 and the mounting frame 213 is adjusted and fixed by the slotted hole 216 and the second bolt 217, thereby adjusting the distance between the cutting torch 3 and the machine tool 1 to avoid special situations. During the cutting process, the cutting torch 3 interferes with the equipment next to the machine tool 1. Finally, by pressing the pin 225, the protrusion 226 is disengaged from the groove 224, thereby releasing the fixation between the rear shell 221 and the rotating shaft 222. This allows the rotating mounting base 214 to rotate and adjust the angle of the cutting torch 3 fixed on the fixing assembly 23. Then, the pressed pin 225 is released, and the spring 227 returns, causing the protrusion 226 to embed into the corresponding groove 224, fixing the rear shell 221 and the rotating shaft 222. This fixes the angle of the cutting torch 3 fixed on the fixing assembly 23 through the mounting base 214, so that the angle of the cutting torch 3 can be adjusted simply by pressing the pin 225.
