DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] See also Figure 1 A gas distribution assembly 11 is fixedly arranged on the semi-automatic flame cutting machine body 1, and the gas distribution assembly 11 is connected to the cutting nozzle body 13 through a pipeline, and a cross bar 2 is installed on the gas distribution assembly 11 through a cross bar mounting frame 12. The gas distribution assembly 11 on the semi-automatic flame cutting machine body 1 can supply fuel to the cutting nozzle body 13 to achieve flame cutting. It is worth noting that this is a prior art, so no further description is given.

[0043] Among them, an adjustment seat 3 is movably provided on the crossbar 2, an internal adjustment member 32 is fixedly provided inside the adjustment seat 3, an inner cavity 21 is adapted to be opened on the crossbar 2 corresponding to the internal adjustment member 32, and an adjustment cavity 321 is opened inside the internal adjustment member 32. A vertical plate 5 is movably provided on the fixed seat 4, a fine-tuning component 51 is provided at the bottom of the vertical plate 5, a cutting nozzle frame 511 is fixedly provided on the fine-tuning component 51, and a cutting nozzle body 13 is installed on the cutting nozzle frame 511. By moving the adjustment seat 3 on the crossbar 2, the X-axis position of the cutting nozzle body 13 can be adjusted, and by moving the vertical plate 5 on the fixed seat 4 vertically, the Z-axis position of the cutting nozzle body 13 can be adjusted. By setting the fine-tuning component 51, the X-axis position and Z-axis position of the cutting nozzle body 13 can be fine-tuned.

[0044] The semi-automatic flame cutting machine body 1 is mounted on a slide rail for movement, and by moving the semi-automatic flame cutting machine body 1 on the slide rail, the Y-axis position of the cutting nozzle body 13 can be adjusted. This is a prior art, so no further details are given.

[0045] See also Figure 2-6 One end of the crossbar 2 is provided with an inner cavity 21, which is adapted to the inner adjustment member 32 on the adjustment seat 3. In this way, when the adjustment seat 3 is sleeved on the crossbar 2 and moves, the inner adjustment member 32 can be adapted to be located in the inner cavity 21 and move synchronously. A clamping member cavity 22 is provided inside the crossbar 2 on one side of the inner cavity 21, and a plurality of clamping members 62 are fixedly arranged in the clamping member cavity 22, and the clamping members 62 are all adapted to the elastic spring 61.

[0046] A lower transverse cavity 23 is provided inside the crossbar 2 at the other side of the inner cavity 21, and a plurality of first limiting cavities 231 are provided above the lower transverse cavity 23. Both the lower transverse cavity 23 and the first limiting cavities 231 are adapted to the first limiting member 341, so that when the first limiting member 341 is located in the lower transverse cavity 23, the first limiting member 341 can move in the X-axis direction; when the first limiting member 341 moves upward and enters the first limiting cavity 231, the first limiting member 341 is locked, and at this time, it cannot move in the X-axis direction.

[0047] See also Figure 7-13 The middle of the adjustment seat 3 is provided with a crossbar cavity 31, and when the crossbar 2 is inserted into the crossbar cavity 31, the adjustment seat 3 can be sleeved and installed on the crossbar 2. An inner adjustment member 32 is provided in the middle of the crossbar cavity 31, and the inner adjustment member 32 is fixedly connected to the adjustment seat 3. An adjustment cavity 321 is provided in the inner adjustment member 32, and a liquid storage capsule 33 is provided in the adjustment cavity 321. The liquid storage capsule 33 is made of a flexible material, and a sealed hydraulic oil is provided inside it, and the liquid storage capsule 33 is separated by a partition 322.

[0048] The liquid storage capsule 33 is fixedly connected with a pressure plate 72 and a movable member 34 on both sides of the partition 322. When the pressure plate 72 moves downward, the liquid storage capsule 33 can be compressed and deformed, so that the liquid in the liquid storage capsule 33 moves toward the movable member 34, thereby pushing the movable member 34 upward. When the movable member 34 moves downward, the liquid in the liquid storage capsule 33 moves toward the pressure plate 72, thereby pushing the pressure plate 72 upward.

[0049] Since the top of the adjustment seat 3 is movably provided with the first pull plate 7 and the second pull plate 8, the bottom of the first pull plate 7 is fixedly provided with a connecting plate 71, which directly extends into the adjustment cavity 321 and is connected to the pressing plate 72, the vertical movement of the pressing plate 72 can be controlled by the first pull plate 7. In addition, the top of the adjustment seat 3 is provided with spring cavities 35 on both sides of the first pull plate 7, and springs 73 are provided in the spring cavities 35, and the springs 73 are connected to the ends of the first pull plate 7. Through the provision of the spring 73, the first pull plate 7 can be pressed downward, thereby ensuring that the pressing plate 72 can stably press the liquid storage capsule 33 downward.

[0050] When the first pull plate 7 is pressed downward, the pressure plate 72 moves downward synchronously, so that one side of the liquid storage capsule 33 can be pressed downward, so that the movable member 34 on the other side of the liquid storage capsule 33 can be pushed outward. Since the first stoppers 341 on the movable member 34 are all extended from the inner adjustment member 32 through the vertical cavity 323, and the extended first stoppers 341 are all located in the lower transverse cavity 23 on the cross bar 2. When the movable member 34 moves upward, the first stoppers 341 in the lower transverse cavity 23 can all move upward into the first stopper cavity 231, so that the adjustment seat 3 can be fixed by the mutual clamping between the first stoppers 341 and the first stopper cavity 231.

[0051] Since the top of the first limiting cavity 231 passes through the cross bar 2, when the first limiting member 341 is located in the first limiting cavity 231, the first N-pole magnet 342 at the end of the first limiting member 341 can be adapted to contact with the second N-pole magnet 422 on the second limiting member 42. At this time, the second N-pole magnet 422 can be away from the first N-pole magnet 342 on the first limiting member 341 by the repulsive magnetic force, so that the second limiting member 42 in the extension cavity 37 can be pushed outward by the repulsive magnetic force. Since the second limiting members 42 are connected by the connecting rod 421, a connecting rod cavity 371 adapted to the connecting rod 421 is provided between the extension cavities 37. Since both ends of the connecting rod cavity 371 are not connected to the outside world, it can be ensured that the second limiting member 42 will not fall off from the extension cavity 37 during the movement.

[0052] When the second pull plate 8 moves downward, the push column 81 can be synchronously located in the push column cavity 36 and move downward, so that the first limiter 341 can be pressed downward by the push column 81, so that the first limiter 341 can return from the first limiter cavity 231 to the lower transverse cavity 23. And when the push column 81 moves downward, the S-pole magnet 811 on the push column 81 can also move downward synchronously. When the S-pole magnet 811 moves to one side of the second limiter 42, the second N-pole magnet 422 on the second limiter 42 can be adsorbed by the S-pole magnet 811 through the magnetic force of attraction, so that the second limiter 42 can be reset and pulled back to the top extension cavity 37 through the magnetic attraction force. And it is worth noting that the corresponding S-pole magnet 811 below the push column cavity 36 is adapted to be provided with an S-pole magnet cavity 361.

[0053] See also Figure 2 , 7 , 9, 15-16, the side clamping seats 41 are fixedly arranged on the fixed seat 4, and the vertical movement of the vertical board 5 can be realized by clamping the side clamping seats 41 on both sides. Since the inner walls of the side clamping seats 41 are fixedly arranged with guide protrusions 411, and the vertical board 5 is provided with guide grooves 53 corresponding to the guide protrusions 411, the stability of the vertical board 5 during vertical movement can be further improved by the adaptation between the guide protrusions 411 and the guide grooves 53.

[0054] A plurality of second limiting cavities 52 are adapted to correspond to the second limiting members 42 on the vertical plate 5. When the second limiting members 42 extend from the top extension cavity 37, the second limiting members 42 can be adapted to be inserted into the second limiting cavities 52 on the vertical plate 5, thereby fixing the vertical plate 5.

[0055] A fine-tuning assembly 51 is provided at the bottom of the vertical plate 5, and a cutting nozzle frame 511 is provided on the fine-tuning assembly 51, and the cutting nozzle body 13 can be installed through the cutting nozzle frame 511. Through the setting of the fine-tuning assembly 51, the X-axis and Z-axis positions of the cutting nozzle frame 511 can be fine-tuned. It is worth noting that the fine-tuning assembly 51 is rotatably provided with an X-axis screw rod and a Z-axis screw rod, and is fixedly provided with an X-axis guide column and a Z-axis guide column adapted to the X-axis screw rod and the Z-axis screw rod, so that the X-axis and Z-axis positions of the cutting nozzle frame 511 can be fine-tuned by rotating the X-axis screw rod and the Z-axis screw rod. It is worth noting that this is a prior art, which does not belong to the main technical problem to be solved in the present technical solution, so it will not be elaborated.

[0056] See also Figure 5 , 13 -16, a reed cavity 6 is opened inwardly on the outer side of the inner adjusting member 32, and an elastic reed 61 is arranged inside the reed cavity 6, and the elastic reed 61 is adapted to the clamping member 62 in the clamping member cavity 22.

[0057] A reed cavity 6 is inwardly opened on the inner wall of the side clamp seat 41 , and an elastic reed 61 is arranged in the reed cavity 6 , and clamps 62 are adapted and arranged on both sides of the vertical plate 5 corresponding to the elastic reed 61 .

[0058] Since a limited gap is set between the clamps 62, and the part of the elastic spring 61 extending from the spring cavity 6 is located in the limited gap between the clamps 62. In this way, when the user moves the adjustment seat 3 or the vertical plate 5, the part of the elastic spring 61 extending out will be compressed into the spring cavity 6 due to the elastic force when it contacts the clamps 62; and when the elastic spring 61 is located in the limited gap between the clamps 62, it will automatically extend from the spring cavity 6 due to the elastic force. In this way, when the adjustment seat 3 or the vertical plate 5 moves, a certain sense of frustration can be brought about by the elastic spring 61 and the clamps 62.

[0059] When the elastic spring 61 on the inner adjusting member 32 is clamped in the limiting gap between the clamps 62 in the clamp cavity 22 , the first limiting member 341 on the adjusting seat 3 is adapted and aligned with the first limiting cavity 231 .

[0060] When the elastic spring sheet 61 on the side clamp seat 41 is clamped in the limiting gap between the clamping members 62 on the side of the vertical plate 5 , the second limiting cavity 52 is adapted and aligned with the top extension cavity 37 .

[0061] In this way, when the user operates the first limiter 341 and the second limiter 42, the user can align the position to be locked by the sense of frustration generated by the limit gap between the elastic spring 61 and the clamp 62, so as to facilitate the user's operation, and the problem of being unable to be locked due to the misalignment of the first limiter 341 and the second limiter 42 with the position to be locked will not occur. It is worth noting that the adaptation setting between the elastic spring 61 and the clamp 62 is a prior art, so it will not be described in detail.

[0062] In this embodiment, the gas distribution assembly 11 on the semi-automatic flame cutting machine body 1 can be provided to supply dye to the cutting nozzle body 13, so that the flame cutting of the workpiece can be achieved through the cutting nozzle body 13. The semi-automatic flame cutting machine body 1 can move along the Y axis by moving on the track; the adjustment seat 3 can move along the crossbar 2 to achieve the X axis movement of the cutting nozzle body 13; the vertical movement between the side clamping seats 41 on both sides of the vertical plate 5 can achieve the Z axis movement of the cutting nozzle body 13. And through the fine adjustment assembly 51, the X axis and Z axis positions of the cutting nozzle body 13 can be finely adjusted.

[0063] Furthermore, when the user needs to adjust the Z-axis position of the cutting nozzle body 13, the user only needs to press the second pull plate 8 downward, and the push column 81 moves downward, and the S-pole magnet 811 on the push column 81 also moves downward synchronously in the S-pole magnet cavity 361. When the S-pole magnet 811 moves downward to one side of the second limiter 42, the second N-pole magnet 422 at the end of the second limiter 42 can be attracted by the S-pole magnet 811, so that the second limiter 42 can be attracted into the top extension cavity 37. At this time, the second limiter 42 stuck in the second limiter cavity 52 is retracted into the top extension cavity 37, and the user can move the vertical plate 5 vertically at this time, so as to adjust the Z-axis position of the cutting nozzle body 13.

[0064] Furthermore, when the user needs to adjust the X-axis position of the cutting nozzle body 13, he only needs to press the second pull plate 8 downward, and the push column 81 can move downward and press the first limiter 341 in the first limit cavity 231 into the lower transverse cavity 23. At this time, the movable member 34 can move downward through the first limiter 341 and press the liquid storage capsule 33, so that the liquid on one side of the liquid storage capsule 33 can flow to the other side and push the pressure plate 72 upward, thereby driving the connecting plate 71 and the first pull plate 7 to push upward synchronously. At this time, the user only needs to grab the first pull plate 7 that is pushed out, and lift the second pull plate 8 upward to reset the bottom of the push column 81 from the first limit cavity 231 to the push column cavity 36. At this time, the user can directly move the adjustment seat 3 on the cross bar 2, so as to adjust the X-axis position of the cutting nozzle body 13.

[0065] Furthermore, when the user needs to fix the adjustment seat 3 and the vertical plate 5 again, he only needs to loosen the first pull plate 7 and the second pull plate 8, and the first pull plate 7 can automatically move downward and reset due to the elastic force of the spring 73. This can drive the connecting plate 71 and the pressing plate 72 to move downward, and the pressing plate 72 presses one side of the liquid storage capsule 33 downward, so that the liquid in the liquid storage capsule 33 can move to the other side and push the movable member 34 upward.

[0066] Thus, the first limiter 341 can be moved upwards into the first limiter cavity 231 again through the movable member 34, thereby fixing the adjustment seat 3. At this time, the push column 81 is lifted upwards by the first limiter 341, thereby driving the second pull plate 8 to move upwards and reset. And when the first limiter 341 is located in the first limiter cavity 231, the first N-pole magnet 342 on the first limiter 341 is located on one side of the second N-pole magnet 422 on the second limiter 42, thereby the second limiter 42 can be pushed out by the repulsive magnetic force between the first N-pole magnet 342 and the second N-pole magnet 422. In this way, the second limiter 42 can be pushed out from the top extension cavity 37 into the second limiter cavity 52 on the vertical plate 5, thereby fixing the vertical plate 5.

[0067] Furthermore, the matching arrangement between the elastic spring 61 and the clamp 62 can make the adjustment seat 3 and the vertical plate 5 feel stuck during the movement. This can not only prevent the adjustment seat 3 and the vertical plate 5 from accidentally sliding during adjustment, but also make the first limiter 341 always aligned with the first limiter cavity 231 during adjustment; and the second limiter cavity 52 always aligned with the top extension cavity 37 through the generated setback. After the adjustment is completed, the user can easily reset the first limiter 341 and the second limiter 42 to fix the adjustment seat 3 and the vertical plate 5 again.

[0068] In this way, the user only needs to press the second pull plate 8 downward to move the upright plate 5 vertically. Alternatively, after the second pull plate 8 is pressed downward, the first pull plate 7 and the second pull plate 8 are pulled up synchronously to move the adjustment seat 3 horizontally. In this way, the X and Z axis directions of the cutting nozzle body 13 can be adjusted quickly, and the user only needs to loosen the first pull plate 7 and the second pull plate 8 to automatically fix the upright plate 5 and the adjustment seat 3 again.

[0069] In the present invention, flame cutting of the workpiece can be achieved through the cutting nozzle body 13 on the semi-automatic flame cutting machine body 1, the adjustment seat 3 can be fixed by the mutual clamping between the first limit piece 341 and the first limit cavity 231, and the vertical plate 5 can be fixed by the mutual clamping between the second limit piece 42 and the second limit cavity 52. ​​The user only needs to control the first pull plate 7 and the second pull plate 8 to manually adjust the position of the adjusting seat 3 and the vertical plate 5 to achieve position adjustment of the cutting nozzle body 13. This method of adjusting the cutting nozzle body 13 is relatively simple and convenient, and is easy for users to use.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
