[0032] Figure 1 , is a schematic diagram of the structure of a height adjustment device in one embodiment.

[0033] In this embodiment, the height adjustment device is used to raise or lower the laser cutting head in the laser and flame composite cutting machine to adjust the distance between the bottom of the laser cutting head and the workpiece to be processed. Figure 1 As shown, the height adjustment device includes a receiving mechanism 10, a height adjustment mechanism 20 and a sensing mechanism 30.

[0034] The receiving mechanism 10 includes a contact assembly 120 and an auxiliary support assembly 140; along the vertical direction, the contact assembly 120 is arranged below the auxiliary support assembly 140; the auxiliary support assembly 140 can surround the cutting head.

[0035] The receiving mechanism 10 may be a functional structure that can be separated from the bottom end surface of the cutting head and contact the side of the cutting head, and cooperate with the sensing mechanism 30 to sense the distance between the contact component 120 and the workpiece to be processed. The contact component 120 may be a sensor component that can contact the surface of the workpiece to be processed and obtain position information. The auxiliary support component 140 may be an annular support structure that can contact the side of the cutting head and provide a supporting force in the vertical direction.

[0036] The height adjustment mechanism 20 includes a sliding assembly 220 and a supporting assembly 240. One end of the sliding assembly 220 is connected to the auxiliary supporting assembly 140. The other end of the sliding assembly 220 is slidably connected to the supporting assembly 240 along the vertical direction. The supporting assembly 240 is connected to the cutting head.

[0037] The height adjustment mechanism 20 may be a functional structure that can contact the side of the cutting head and limit the position in the horizontal direction, and can raise or lower the receiving mechanism 10 and the cutting head in the vertical direction. The sliding assembly 220 may be a sliding drive assembly that can provide a driving force in the vertical direction to act on the cutting head. The support assembly 240 may be a plate-like support structure that can be fixedly contacted with the side or end face of the cutting head and limit the degree of freedom of the cutting head in the vertical and horizontal directions.

[0038] It should be noted that, compared with the support assembly 240 in the height adjustment mechanism 20, the auxiliary support assembly 140 in the receiving mechanism 10 always remains connected to the side or end face of the laser cutting head and limits the cutting head during the processing, while the auxiliary support assembly 140 can be detached from the bottom end face of the cutting head in some height adjustment scenarios (such as measuring the distance between the laser cutting head and the workpiece to be processed).

[0039] Alternatively, if Figure 2 As shown, the sliding assembly 220 includes a first connecting member 2220 , a second connecting member 2240 , a sliding member 2260 and a driving member 2280 , the first connecting member 2220 is connected between the sliding member 2260 and the auxiliary support assembly 140 , and the second connecting member 2240 is connected between the sliding member 2260 and the driving member 2280 .

[0040] The first connecting member 2220 may be a connecting functional member capable of fixedly connecting the auxiliary supporting assembly 140 in the receiving mechanism 10 and the sliding assembly 220 in the height adjustment mechanism 20. The second connecting member 2240 may be a connecting functional member capable of fixedly connecting the driving member 2280 and the sliding member 2260. The sliding member 2260 may be a plate-shaped slide rail structure capable of being slidably connected to the supporting assembly 240. The driving member 2280 may be a driver capable of driving the supporting assembly 240 to slide in a vertical direction relative to the sliding member 2260.

[0041] Optionally, the driving member 2280 includes a driving sub-member, a first driving positioning sub-member and a second driving positioning sub-member, the first driving positioning sub-member is connected between the driving sub-member and the sliding assembly 220 , and the second driving positioning sub-member is connected between the driving sub-member and the supporting assembly 240 .

[0042] The driving sub-component may be a cylinder driver, a screw driver, a hydraulic driver, a driving motor, etc. The first driving positioning sub-component may be a threaded structure that fixes one end of the driving sub-component close to the receiving structure to the sliding component 220. The second driving positioning sub-component may be a screw structure that fixes the middle of the driving sub-component to the supporting component 240.

[0043] Optionally, a corner connection portion is provided on the side of the sliding member 2260 close to the receiving mechanism 10, and the first connecting member 2220 is connected to the auxiliary support assembly 140 through the corner connection portion, which can ensure that the auxiliary support assembly 140 arranged in the horizontal direction and the sliding assembly 220 arranged in the vertical direction are smoothly and stably connected, ensure the synchronization of the movement of the two, and improve the accuracy of height adjustment.

[0044] Alternatively, if Figure 3 As shown, the support assembly 240 includes a third connecting member 2420, a fourth connecting member 2440, an elastic member 2460 and a support frame 2480, the third connecting member 2420 is connected between the elastic member 2460 and the support frame 2480, and the fourth connecting member 2440 is connected between the support frame 2480 and the sensing mechanism 30. The elastic expansion and contraction direction of the elastic member 2460 is set along the vertical direction, and the elastic expansion and contraction end of the elastic member 2460 is connected to the sliding assembly 220.

[0045] The third connecting member 2420 may be a connecting functional member capable of fixing the elastic member 2460 to the support frame 2480. The fourth connecting member 2440 may be a connecting functional member capable of fixing the sensing mechanism 30 to the support frame 2480. The elastic member 2460 may be an elastic functional member capable of outputting elastic telescopic force in the vertical direction and applying the elastic telescopic force to the sliding assembly 220. The support frame 2480 may be a mounting frame that is slidably connected to the sliding assembly 220, fixedly connected to the elastic telescopic end of the elastic member 2460, and in contact with the side of the cutting head.

[0046] Optionally, the elastic expansion and contraction direction of the elastic member 2460 is arranged in the vertical direction, including: the elastic expansion and contraction direction of the elastic member 2460, the driving direction of the driving member 2280 of the sliding assembly 220 and the geometric center line of the support frame 2480 in the vertical direction are coplanar. In the height adjustment scenario where the distance between the bottom of the cutting head and the workpiece to be processed needs to be measured, after the machining zero point calibration is completed, the sliding assembly 220 moves downward, while driving the elastic member 2460 connected to the sliding assembly 220 to quickly respond to forced compression, and drives the contact assembly 120 and the auxiliary support assembly 140 in the receiving mechanism 10 to detach from the cutting head and move downward basically synchronously with the sliding assembly 220, so that the contact assembly 120 can be in contact with the surface of the workpiece to be processed and the distance measurement can be achieved.

[0047] The sensing mechanism 30 is disposed on the top of the supporting assembly 240 and is capable of sensing the distance between the contact assembly 120 and the workpiece to be processed in the vertical direction.

[0048] The sensing mechanism 30 may be a distance measuring sensor that can be used in conjunction with the contact component 120 in the receiving mechanism 10 to detect the distance between the contact component 120 and the workpiece to be processed.

[0049] The height adjustment device provided in this embodiment, during the laser and flame composite cutting process of the workpiece, the receiving mechanism 10 can be separated from the bottom end face of the cutting head to contact the side face of the cutting head and provide a supporting force in the vertical direction through the auxiliary support component 140 surrounding the side face of the cutting head, and the height adjustment mechanism 20 contacts the side face or end face of the cutting head through the support component 240 connected to the cutting head and limits the position in the horizontal direction or the vertical direction, and the contact component 120 arranged below the auxiliary support component 140 in the receiving mechanism 10 in the vertical direction and the sensing mechanism 30 arranged on the top of the support component 240 can cooperate to The device can sense the distance between the contact component 120 and the workpiece to be processed in the vertical direction. When the distance needs to be adjusted (such as machining zero point calibration or flame cutting in progress), the height adjustment mechanism 20 raises or lowers the receiving mechanism 10 and the cutting head in the vertical direction through the sliding component 220 that is slidably connected to the support component 240, thereby ensuring the normal zero point calibration and follow-up height control of the cutting head, while improving the large deviation between the actual cutting height and the cutting height measurement value caused by the accumulation of high-temperature slag on the device and the melting of the probe due to high temperature, so that the device can be used stably for a longer time, ensuring the machining accuracy and stability of the composite cutting.

[0050] Figure 4 , is a schematic diagram of the specific structure of the receiving mechanism 10 in an embodiment.

[0051] In this embodiment, if Figure 4As shown, the receiving mechanism 10 includes a contact assembly 120 and an auxiliary support assembly 140, the auxiliary support assembly 140 includes a square support member 1420 and a side positioning member 1440, the end face of the square support member 1420 can contact the side of the cutting head, and the first connecting member 2220 is connected to the side positioning member 1440 through the corner connecting part.

[0052] The square support member 1420 may be a hollow square support ring that can be adapted to the side dimensions of the cutting head so that the cutting head can partially pass through. The side positioning member 1440 may be a positioning functional member that is disposed on a side surface close to the sliding member 2260 and can fix the receiving mechanism 10 to the corner connection portion of the sliding member 2260.

[0053] The contact assembly 120 includes a contact probe 1220 and a probe positioning member 1240 . A probe through hole is provided on the square support member 1420 , and the probe positioning member 1240 passes through the probe through hole and is connected to the contact probe 1220 .

[0054] Optionally, the contact probes 1220 and the probe positioning members 1240 are evenly distributed at the center positions around the square support member 1420 .

[0055] like Figure 5 As shown, in the distance measurement state (i.e. when the distance between the laser cutting head and the workpiece to be processed needs to be measured), the contact component 120 descends to contact the surface of the workpiece to be processed, and the sensing mechanism 30 detects the distance between the contact probe 1220 in the contact component 120 and the bottom end face of the cutting head. After the machining zero point calibration is completed, the distance between the bottom end face of the cutting head and the surface of the workpiece to be processed will be controlled at a constant distance. When flame cutting is performed, the sliding component 220 (such as a cylinder drive component) drives the contact component 120 and the auxiliary support component 140 to rise upward, so that the contact component 120 is separated from the bottom end face of the cutting head to prevent the slag from melting and accumulating the probe and affecting the follow-up distance measurement. Figure 6 As shown, during the compound cutting process, by controlling the on and off of the cylinder air inlet and outlet, the contact assembly 120 and the auxiliary support assembly 140 can be lowered at a specific time point for distance measurement, thereby preventing the contact probe 1220 from being in contact with the workpiece to be processed all the time, which may easily lead to melting due to high temperature.

[0056] The receiving mechanism 10 provided in this embodiment, through the cooperation of the square support member 1420, the side positioning member 1440, the contact probe 1220 and the probe positioning member 1240, can be detached from the bottom end face of the cutting head during flame cutting to change the distance between the receiving mechanism 10 and the workpiece to be processed, until it contacts the side of the cutting head and provides a supporting force in the vertical direction, while improving the large deviation between the actual cutting height and the cutting height measurement value caused by the accumulation of high-temperature slag on the device and the melting of the probe due to high temperature, further limiting the cutting head is achieved, improving the problem of accidental shaking caused by factors such as accidental collision of the cutting head, and effectively improving the working stability of the height adjustment device; and when it is necessary to measure the distance between the laser cutting head and the workpiece to be processed, it can be parallel to the bottom end face of the cutting head, that is, the contact probe 1220 in the contact assembly 120 contacts the surface of the workpiece to be processed, thereby realizing distance measurement and ensuring the processing accuracy and stability of the composite cutting.

[0057] The present application also provides a laser and flame composite processing head, which includes a height adjustment device as in the above embodiment.

[0058] The present application also provides a processing device, which includes a height adjustment device as described in the above embodiment.

[0059] The division of the various modules in the above-mentioned height adjustment device is only for illustration. In other embodiments, the height adjustment device can be divided into different modules as needed to complete all or part of the functions of the above-mentioned height adjustment device.

[0060] The height adjustment device and processing equipment provided in the above-mentioned embodiment, during the laser and flame composite cutting process of the workpiece, the receiving mechanism 10 can be separated from the bottom end face of the cutting head to contact the side face of the cutting head and provide a supporting force in the vertical direction through the auxiliary support component 140 surrounding the side face of the cutting head, and the height adjustment mechanism 20 contacts the side face or end face of the cutting head through the support component 240 connected to the cutting head and limits the position in the horizontal direction or the vertical direction, and the contact component 120 arranged below the auxiliary support component 140 in the receiving mechanism 10 in the vertical direction and the sensing mechanism 30 arranged on the top of the support component 240 can cooperate to sense the contact component The distance between the component 120 and the workpiece to be processed in the vertical direction. When the distance needs to be adjusted (such as machining zero point calibration or flame cutting is in progress), the height adjustment mechanism 20 raises or lowers the receiving mechanism 10 and the cutting head in the vertical direction through the sliding component 220 that is slidably connected to the supporting component 240, thereby ensuring the normal zero point calibration and follow-up height control of the cutting head, while improving the large deviation between the actual cutting height and the cutting height measurement value caused by the accumulation of high-temperature slag on the device and the melting of the probe due to high temperature, so that the device can be used stably for a longer time, ensuring the machining accuracy and stability of composite cutting, which has important economic value and promotion and practical value.
