Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a laser cutting head replacement structure. Background Technology

[0002] Laser cutting differs from traditional blade rotation cutting. Instead, it uses a laser cutting head to irradiate the material with a laser beam, heating the irradiated area until it vaporizes and forms a hole. As the laser head or the material moves, the hole becomes a slit, thus cutting the material open.

[0003] After working for a period of time, laser cutting heads may need to be disassembled for inspection and maintenance, or replaced with a new laser cutting head, or replaced with a laser cutting head of a different power or type, due to reasons such as operational errors leading to collisions between the laser cutting head and materials, thermal runaway, damage to electronic components, lens blurring, or maintenance. In such cases, it is necessary to replace the laser cutting head by changing its structure.

[0004] The existing laser cutting head replacement connector is relatively simple. It is usually a metal block with threaded holes, which is installed on a slide or bracket by bolts or other means. The laser cutting head is mainly connected to the replacement structure by bolts. There are usually four or more bolts. During operation, the operator needs to continuously rotate the bolts with a wrench to loosen or tighten them. This operation needs to be done four times. During this process, the bolt support is weak. The operator needs to hold the laser cutting head with one hand to prevent it from falling, and control the bolts with the other hand. This makes the operation not only cumbersome and time-consuming, but also laborious. If the operator slips, the laser cutting head may fall and cause damage. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a laser cutting head replacement structure to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting head replacement structure, comprising a fixing plate, a laser cutting head body, and a mounting plate. Multiple fixing bolts are provided on both sides of the back of the fixing plate. Slide grooves are formed on both sides of the outer surface of the fixing plate. Bidirectional screws penetrate both sides of the fixing plate, and two adjusting brackets are connected between the bidirectional screws and the slide grooves. Four trapezoidal screws penetrate the tops of the two adjusting brackets, and four adjusting seats are connected to the outside of each of the four trapezoidal screws. Insert rods are fixed to the outer surfaces of the four adjusting seats, and pins penetrate the tops of the insert rods.

[0007] By adopting the above technical solution, during disassembly, the operator first holds the laser cutting head body horizontally to prevent it from falling after the pin is removed. Then, the operator pulls the pin upwards to stop the laser cutting head from being locked. Finally, the operator simply removes the laser cutting head horizontally to complete the disassembly operation. When installing other laser cutting heads and the mounting plate and the insertion rod positions do not correspond, the operator can adjust the distance between the two adjusting brackets by rotating the bidirectional screw, thereby adjusting the lateral distance between the four insertion rods. The operator can also adjust the distance between the four adjusting seats by rotating the four trapezoidal screws individually. The distance between the four insert rods is adjusted by the presence of a round hole to prevent the adjusting seat from contacting the two trapezoidal screws and causing conflict. During installation, the operator moves the laser cutting head body horizontally until it is in contact with the adjusting frame. At this point, the mounting plate will be penetrated by the insert rods. The weight of the laser cutting head is borne by the insert rods, adjusting seat, and other structures. The operator only needs to hold the laser cutting head body down, without having to lift or grip it, which is more labor-saving. Then, the operator inserts the pins into the insert rods from top to bottom to limit the laser cutting head body and prevent it from falling off due to horizontal displacement.

[0008] Furthermore, the adjustment frame is provided with "T"-shaped sliders on both the upper and lower back sides, and the adjustment frame is slidably connected to the slide groove via the sliders.

[0009] By adopting the above technical solution, the adjusting frame is guided by the slider and the slide groove during the rotation of the bidirectional screw, so as to prevent the adjusting frame from rotating with the bidirectional screw, and the T-shaped slider prevents the adjusting frame from falling out of the slide groove.

[0010] Furthermore, the adjusting bracket is threadedly connected to a bidirectional screw.

[0011] By adopting the above technical solution, workers can adjust the distance between the two adjustment frames by rotating the bidirectional screw, thereby adjusting the lateral distance between the four insertion rods.

[0012] Furthermore, the top and bottom sides of the adjusting seat are threadedly connected to the trapezoidal screw, and the adjusting seat is slidably connected to the adjusting frame.

[0013] By adopting the above technical solution, workers can adjust the distance between the four adjustment seats by individually rotating the four trapezoidal screws, thereby adjusting the longitudinal distance between the four insertion rods.

[0014] Furthermore, four circular holes are respectively provided on the other side of the top and the other side of the bottom of the four adjustment seats, and the diameter of the circular holes is larger than the diameter of the trapezoidal screw.

[0015] By adopting the above technical solution, the staff can adjust the distance between the four adjusting seats by rotating the four trapezoidal screws. Due to the existence of the round holes, it is avoided that the adjusting seats will contact the two trapezoidal screws and cause conflicts.

[0016] Further, the cross-section of the bolt pin is in an inverted "mountain" shape, and the bolt pin is detachably connected to the bolt rod.

[0017] By adopting the above technical solution, during disassembly, the staff first holds the main body of the laser cutting head horizontally to prevent the main body of the laser cutting head from falling after the bolt pin is removed. Then, the staff pulls out the bolt pin upward to end the limitation of the laser cutting head. Finally, the staff only needs to remove the laser cutting head horizontally to complete the disassembly operation.

[0018] Further, the main body of the laser cutting head is located in front of the fixing plate, and four mounting plates are respectively fixed on both sides of the main body of the laser cutting head. An interface is arranged on the top of the main body of the laser cutting head, and a laser head is arranged at the bottom of the main body of the laser cutting head.

[0019] By adopting the above technical solution, after the main body of the laser cutting head is installed, the staff connects the cable to the interface. After the laser cutting head generates a laser beam, it is emitted through the laser head, thereby cutting the material.

[0020] Further, the mounting plate is detachably connected to the bolt rod, and the bolt pin abuts against the mounting plate.

[0021] By adopting the above technical solution, during installation, the staff directly moves the main body of the laser cutting head horizontally until it fits with the adjusting frame. At this time, the mounting plate will be penetrated by the bolt rod. Then, the staff inserts the bolt pin into the bolt rod from top to bottom to limit the main body of the laser cutting head, avoiding the phenomenon that the main body of the laser cutting head is displaced horizontally and falls off.

[0022] Further, hexagonal protrusions are fixed at both ends of the bidirectional screw, and hexagonal protrusions are fixed at the top ends of two of the trapezoidal screws and the bottom ends of the other two trapezoidal screws.

[0023] By adopting the above technical solution, the hexagonal protrusions at both ends of the bidirectional screw facilitate the staff to rotate the bidirectional screw with a wrench, making the operation more labor-saving; and the hexagonal protrusions at one end of the trapezoidal screw facilitate the staff to rotate the trapezoidal screw with a wrench, making the operation more labor-saving. Moreover, the hexagonal protrusions on the four trapezoidal screws are two on the top and two on the bottom, corresponding to the two upper adjusting seats and the two lower adjusting seats, which is convenient for the staff to identify which adjusting seat the trapezoidal screw for operation corresponds to.

[0024] To sum up, the main beneficial effects of the present utility model are as follows:

[0025] 1. This utility model, through the setting of the insert rod and pin, allows for easy installation. During installation, the laser cutting head body is moved horizontally until it aligns with the adjusting frame. At this point, the mounting plate is penetrated by the insert rod, and the weight of the laser cutting head is supported by the insert rod, adjusting base, and other structures. Only the laser cutting head body needs to be held down during this process; no force is required to lift or grip it, making it much easier. Then, the pin is inserted into the insert rod from top to bottom to limit the laser cutting head body, preventing horizontal displacement and potential detachment. The operation is very quick and convenient. For disassembly, first hold the laser cutting head body horizontally to prevent it from falling after removing the pin. Then, pull the pin upwards to stop limiting the laser cutting head. Finally, simply remove the laser cutting head horizontally to complete the disassembly. The operation is time-saving, labor-saving, and very convenient.

[0026] 2. This utility model, through the arrangement of a bidirectional screw, adjusting bracket, trapezoidal screw, and adjusting seat, allows for adjustments to the lateral spacing between the four insert rods when the mounting plate and the insertion rod positions do not correspond when installing other laser cutting heads. This can be achieved by rotating the bidirectional screw to adjust the distance between the two adjusting brackets, thus adjusting the lateral spacing between the four insert rods. Alternatively, the distance between the four adjusting seats can be adjusted by individually rotating the four trapezoidal screws, thus adjusting the longitudinal spacing between the four insert rods. The presence of a circular hole prevents the adjusting seat from contacting the two trapezoidal screws and causing conflict. This facilitates adjustment to accommodate a wider variety of laser cutting heads. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following will describe the embodiments of the present utility model according to its overall structure.

[0034] Embodiment 1:

[0035] A laser cutting head replacement structure, as Figures 1-4 shown, includes a fixed plate 1, a laser cutting head main body 3 and a mounting plate 4. On both sides of the back of the fixed plate 1, a plurality of fixing bolts 2 are provided. Through the fixing bolts 2, it is convenient to install the fixed plate 1 on a sliding table or a bracket; on both sides of the outer surface of the fixed plate 1, chutes 8 are opened. A bidirectional screw 7 penetrates through both sides of the fixed plate 1. Between the bidirectional screw 7 and the chute 8, two adjusting frames 9 are connected. The adjusting frame 9 is threadedly connected to the bidirectional screw 7. Above and below the back of the adjusting frame 9, sliders in the shape of "T" are provided. The adjusting frame 9 is slidably connected to the chute 8 through the sliders. Workers can adjust the distance between the two adjusting frames 9 by rotating the bidirectional screw 7, thereby adjusting the horizontal distance between the four inserting rods 12; four trapezoidal screws 10 penetrate through the tops of the two adjusting frames 9 respectively. Four adjusting seats 11 are respectively connected to the outer parts of the four trapezoidal screws 10. One side of the top and one side of the bottom of the adjusting seat 11 are threadedly connected to the trapezoidal screw 10. The adjusting seat 11 is slidably connected to the adjusting frame 9. On the other side of the top and the other side of the bottom of the four adjusting seats 11, four circular holes are respectively opened. The diameter of the circular hole is larger than the diameter of the trapezoidal screw 10. Workers can also adjust the distance between the four adjusting seats 11 by separately rotating the four trapezoidal screws 10, thereby adjusting the vertical distance between the four inserting rods 12. During this period, due to the existence of the circular holes, it is avoided that the adjusting seat 11 contacts the two trapezoidal screws 10 and causes conflicts; on the outer surfaces of the four adjusting seats 11, inserting rods 12 are respectively fixed. An inserting pin 13 penetrates through the top of the inserting rod 12. The cross-section of the inserting pin 13 is in the shape of an inverted "mountain". The inserting pin 13 is detachably connected to the inserting rod 12. The mounting plate 4 is detachably connected to the inserting rod 12. The inserting pin 13 abuts against the mounting plate 4. During installation, workers directly move the laser cutting head main body 3 horizontally until it fits with the adjusting frame 9. At this time, the mounting plate 4 will be penetrated by the inserting rod 12. At this time, the weight of the laser cutting head is borne by structures such as the inserting rod 12 and the adjusting seat 11. During this period, workers only need to hold the laser cutting head main body 3, without having to hold it up with force, which is relatively labor-saving. After that, workers can insert the inserting pin 13 into the inserting rod 12 from top to bottom to limit the laser cutting head main body 3, avoiding the phenomenon that the laser cutting head main body 3 is horizontally displaced and falls off.

[0036] Refer to Figure 1 , in the above embodiment, the laser cutting head main body 3 is located in front of the fixed plate 1. Four mounting plates 4 are respectively fixed on both sides of the laser cutting head main body 3, which is convenient for installation; an interface 6 is provided on the top of the laser cutting head main body 3, which is convenient for connecting an optical fiber to make the laser cutting head main body 3 generate a laser beam; a laser head 5 is provided at the bottom of the laser cutting head main body 3. The laser beam is emitted through the laser head 5 to cut materials.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are made for ease of operation.

[0039] See Figures 1-4 In the above embodiment, both ends of the bidirectional screw 7 are fixed with hexagonal protrusions. The hexagonal protrusions at both ends of the bidirectional screw 7 make it easier for the operator to rotate the bidirectional screw 7 with a wrench, making the operation more labor-saving. The top ends of the two trapezoidal screws 10 and the bottom ends of the other two trapezoidal screws 10 are fixed with hexagonal protrusions. The hexagonal protrusions at one end of the trapezoidal screw 10 make it easier for the operator to rotate the trapezoidal screw 10 with a wrench, making the operation more labor-saving. The hexagonal protrusions on the four trapezoidal screws 10 are two on top and two on the bottom, corresponding to the two upper adjustment seats 11 and the two lower adjustment seats 11, making it easier for the operator to identify which adjustment seat 11 the trapezoidal screw 10 corresponds to.

[0040] The implementation principle of this utility model is as follows: First, during disassembly, the operator presses down on the laser cutting head body 3 in the horizontal direction to prevent the laser cutting head body 3 from falling after the pin 13 is removed. Then, the operator pulls the pin 13 upward to end the limitation on the laser cutting head. Finally, the operator only needs to remove the laser cutting head in the horizontal direction to complete the disassembly operation.

[0041] When installing other laser cutting heads and the mounting plate 4 and the insertion rod 12 are not aligned, the operator can adjust the distance between the two adjusting brackets 9 by rotating the bidirectional screw 7, thereby adjusting the lateral distance between the four insertion rods 12. During this process, the hexagonal protrusions at both ends of the bidirectional screw 7 make it easier for the operator to rotate the bidirectional screw 7 with a wrench, making the operation more effortless. The operator can also adjust the distance between the four adjusting seats 11 by rotating the four trapezoidal screws 10 individually, thereby adjusting the longitudinal distance between the four insertion rods 12. During this process, the presence of round holes prevents the adjusting seat 11 from contacting the two trapezoidal screws 10 and causing conflict. Furthermore, the hexagonal protrusion at one end of the trapezoidal screw 10 makes it easier for the operator to rotate the trapezoidal screw 10 with a wrench, making the operation more effortless. The hexagonal protrusions on the four trapezoidal screws 10 are two on top and two on the bottom, corresponding to the two upper adjusting seats 11 and the two lower adjusting seats 11, making it easier for the operator to identify which adjusting seat 11 the trapezoidal screw 10 corresponds to.

[0042] During installation, the operator moves the laser cutting head body 3 horizontally until it is in contact with the adjusting frame 9. At this time, the mounting plate 4 will be penetrated by the insertion rod 12. The weight of the laser cutting head is supported by the insertion rod 12, adjusting seat 11 and other structures. During this process, the operator only needs to hold the laser cutting head body 3, without having to lift or grasp it forcefully, which is more labor-saving. Afterwards, the operator inserts the pin 13 into the insertion rod 12 from top to bottom to limit the laser cutting head body 3, preventing the laser cutting head body 3 from falling off due to horizontal displacement. This is suitable for laser cutting with low precision requirements, such as cutting materials.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
