[0036] mechanism, the welding head of the present utility model can be flexibly adjusted in three-dimensional space, so as to adapt to the welding requirements of workpieces with different shapes and specifications, and improve the versatility and adaptability of the equipment.
[0037] (2) The adjustment mechanism of the present utility model is simply designed, and the adjustment process is convenient and fast, reducing the complexity and

However, if the adjustment in multiple angles is realized, the structure will be relatively more complex. If the adjustment is controlled by an electric or pneumatic method, although it can achieve convenient adjustment, the adjustment of the welding head is mostly not complex, and the cost of the electric or pneumatic method is higher, the maintenance is more cumbersome, and the electricity cost is also increased. Therefore, manual adjustment is more advantageous. However, in the existing manual adjustment, most of them are either with a cumbersome structure or the adjustment orientation cannot meet the requirements. Therefore, in this application, a height adjustment mechanism, an angle adjustment mechanism, a first adjustment mechanism, and a second adjustment mechanism are integrally arranged. The overall structure is compact and lightweight, occupies a small area, can adapt to the requirements of various scenarios, has more adjustment orientations, and is also more convenient for maintenance.

[0056] When current ultra-high strength steel is applied to roll forming, there are different welding requirements. To meet the weld forming requirements of a variety of different products, this application proposes a laser welding head device with adjustable angles in a roll forming equipment, which is specifically as follows:
[0057] As shown in FIGS. 1-3, the structure of this application is mainly symmetrically arranged with the positioning die 1 of the roll forming equipment. The positioning die 1 plays a role in supporting and positioning the welded product. The laser welding head device of this application meets the welding work of a variety of welded products in the positioning die 1.
[0058] As shown in FIGS. 1-3, the laser welding head device of this application mainly consists of a first adjustment mechanism 2, a second adjustment mechanism 3 that reciprocates on the first adjustment mechanism 2, an angle adjustment mechanism 4 installed on the second adjustment mechanism 3, and a height adjustment mechanism 5 detachably installed on the angle adjustment mechanism 4, and a welding head 7 connected to the height adjustment mechanism 5 through a first connecting shaft 6; through the mutual cooperation between these structures, the overall equipment is manually adjusted in multiple directions to meet the adjustment of the roll forming equipment based on different welding requirements, and reduce the need to disassemble and reinstall the welding equipment adapted to the orientation again when changing the production product.
[0059] As shown in FIGS. 1 and 4, the first adjustment mechanism 2 and the second adjustment mechanism 3 have the same structure and are connected to each other, and they form a cross shape after connection. When the first adjustment mechanism 2 works, it can cause the second adjustment mechanism 3 and the structures installed on the second adjustment mechanism 3 to reciprocate along the direction of the first adjustment mechanism 2. When the second adjustment mechanism 3 moves, it can cause the angle adjustment mechanism 4 and the structures installed on the angle adjustment mechanism 4 to reciprocate along the direction of the second adjustment mechanism 3. During the movement of the first adjustment mechanism 2 and the second adjustment mechanism 3, the welding head 7 is driven to move, so that the welding head 7 can be adjusted along the cross-shaped movement trajectory during the movement.
[0060] Furthermore, in an embodiment, when the first adjustment mechanism 2 is horizontally installed on the support surface, the welding head 7 moves back and forth, left and right based on the movement of the first adjustment mechanism 2 and the second adjustment mechanism 3; in another embodiment, the first adjustment mechanism 2 is vertically (the vertical direction is not limited to perpendicular, and it can also be vertically inclined) installed and fixed on the support surface, and it can complete the movement trajectory of back and forth, up and down. The installation methods of the two embodiments are determined based on the actual situation. No matter which embodiment is selected, it will not affect the use of the welding head 7.
[0061] Among them, the first adjusting mechanism 2 includes a bottom plate 21, a first sliding table 22, a handwheel 23 and a first locking member 24. The bottom plate 21 is used to support and install the first sliding table 22, the handwheel 23 and the first locking member 24. The first sliding table 22 is fixedly installed on the bottom plate 21. The handwheel 23 is connected to the input end of the first sliding table 22. When the handwheel 23 rotates, the guide rail system in the first sliding table 22 makes a reciprocating motion. The bottom of the first locking member 24 is fixedly connected to the bottom plate 21, and its top is sleeved at the input end of the first sliding table 22.
[0062] The bottom plate 21 is used to determine the installation position according to actual needs and is fixed on a supporting surface through structures such as connecting pieces or screws. The first sliding table 22 is fixedly installed on the bottom plate 21 to work. The first sliding table 22 is an existing manually controlled sliding table, which includes a guiding system (slider and ball) and a lead screw and other structures. Since it is a common existing structure, this application will not elaborate too much. The handwheel 23 is installed at the lead screw at the input end of the first sliding table 22, and a first locking member 24 is provided at the lead screw at the input end. When the handwheel 23 rotates to cause the guiding system of the first sliding table 22 to move, the welding head 7 is adjusted in orientation. After determining the position, it is locked by the first locking member 24. At this time, the handwheel 23 cannot rotate again, and the adjustment work is completed.
[0063] Further explanation, the first locking member 24 can adopt any one of the existing pressing plate type screw locking, eccentric clamping or mechanical brake, etc. At the same time, in order to observe whether the first sliding table 22 of the first adjusting mechanism 2 and the second adjusting mechanism 3 is bent and deviated after long-term use, a measuring mark 211 is provided on the first locking member 24. One end of the measuring mark 211 far from the first locking member 24 is bent and located above the handwheel 23. The gap between the bent part of the measuring mark 211 and the handwheel 23 is one centimeter. During specific inspections, the gap can be checked through a measuring device. If it is too large or too small, it means that the various structural brackets of the first adjusting mechanism 2 or the second adjusting mechanism 3 have deformed, etc., so as to detect the situation at this position and reduce the risk of discovering problems only when the subsequent loss is large.
[0064] The bottom plate in the second adjusting mechanism 3 is installed and fixed in the guide rail system of the first sliding table 22. By rotating the handwheel 23, the second adjusting mechanism 3 is driven to move through the guide rail system. The guide rail system of the second adjusting mechanism 3 is connected to the angle adjusting mechanism 4. When the second adjusting mechanism 3 rotates through the handwheel, it will drive the angle adjusting mechanism 4 to move.
[0065] Referring to FIG. 5, after adjustment by the first adjustment mechanism 2 and the second adjustment mechanism 3, the welding head 7 has been adjusted to a generally required orientation; to further precisely position the orientation of the welding head 7, an angle adjustment mechanism 4 is provided on the second adjustment mechanism 3; wherein, the angle adjustment mechanism 4 includes a base 41, a large gear 42, and a small gear 43. The base 41 is installed on the guide rail system of the second adjustment mechanism 3. The large gear 42 is rotatably provided on the base 41, and the small gear 43 is located above the base 41 and meshes with the large gear 42.
[0066] The large gear 42 and the small gear 43 are installed on the base 41, and the base 41 serves the function of connection and installation; the large gear 42 is connected to the base 41 through a rotating shaft, and the small gear 43 is located beside the large gear 42 and is installed on the base 41. Among them, the small gear 43 meshes with the large gear 42. When the small gear 43 rotates, it can drive the large gear 42 to rotate, causing the welding head 7 to move along a circular trajectory to make an orientation adjustment.
[0067] Among them, in order to prevent the small gear 43 from rotating again after adjustment and causing the rotation of the large gear 42, a second locking member 411 is provided at the bottom of the base 41. The second locking member 411 is connected to the small gear 43, and the small gear 43 is locked by the second locking member 411 to ensure the stability of the large gear 42 by no longer rotating.
[0068] The adjustment of the circular track is completed through the angle adjustment mechanism 4. At this time, this structure already has multiple orientation adjustments and can meet the needs of adapting to the welding of various products. However, deficiencies are still found in production; for example, there is still a deviation that cannot be overcome between the products produced subsequently and the previous group of products.
[0069] For example, in an embodiment, when the first adjustment mechanism 2 is installed horizontally (as shown in FIG. 1), then during adjustment, it can be adjusted in the ways of left - right, front - back, and circular movement. However, when making this adjustment, the height of the welding head 7 from the installation position of the first adjustment mechanism 2 in a straight - line distance will not change; then when the product in the equipment is a little higher or lower, the welding head 7 cannot accurately perform the welding work. In another embodiment, when the first adjustment mechanism 2 is installed vertically (as shown in FIG. 2), during adjustment, it can be adjusted in the ways of up - down, front - back, and circular movement. However, under this adjustment, the height of the welding head 7 from the installation position of the first adjustment mechanism 2 in a straight - line distance will not change. Then when the product in the equipment is a little to the left or right, the welding head 7 cannot accurately perform the welding work.
[0070] Reference may be made to FIGS. 6-10. To solve this problem, a height adjustment mechanism 5 is provided in this application. The height adjustment mechanism 5 includes a disc 51, a shaft block 52, and a shaft ball 53. The disc 51 is fixedly installed on the upper surface of the angle adjustment mechanism 4. The shaft block 52 is slidably disposed within the disc 51. When the shaft block 52 rotates on the disc 51, the connection depth between its bottom and the disc 51 increases from small to large. When the shaft block 52 rotates clockwise, the front end of the welding head 7 faces downward. When the shaft block 52 is in the neutral position, the welding head 7 is originally set. When the shaft block 52 rotates counterclockwise, the front end of the welding head 7 faces upward. The shaft ball 53 is disposed in the middle of the connection between the disc 51 and the shaft block 52 for stability.
[0071] Two left inclined holes 511 and two right inclined holes 512 are coaxially distributed on the surface of the disc 51. Chute grooves are provided in both the two left inclined holes 511 and the two right inclined holes 512. The chute grooves in the two left inclined holes 511 change from smooth to inclined upward in the clockwise rotation direction of the disc 51. The chute grooves in the two right inclined holes 512 change from smooth to inclined upward in the counterclockwise rotation direction of the disc 51. The shaft block 52 includes a trapezoidal block 521 and a second connecting shaft 522. The trapezoidal block 521 is fixedly connected to the disc 51 by bolts. The trapezoidal block 521 is in the shape of a right trapezoid, which is inclined at the starting position. The two right-angle parts thereof are movably connected to the two right inclined holes 512 through the second connecting shaft 522, and the two parts away from the right angle are movably connected to the left inclined holes 511 through the second connecting shaft 522.
[0072] Reference may be made to FIGS. 9-10. In another embodiment, the shaft block 52 may further include a square block 523 and a mounting shaft 524. The mounting shaft 524 is the same as the second connecting shaft 522, and its specific starting form is not limited, as long as the bottom surface of the shaft block 52 is horizontal and the square surface at the starting time is satisfied. Secondly, whether it is the square block 523, the trapezoidal block 521, or others, there is a certain gap between them and the disc 51 to satisfy the rotation radian of the shaft block 52.
[0073] Referring to FIG6, when the shaft block 52 does not move, the connection between the shaft block 52 and the two left oblique holes 511 and the two right oblique holes 512 is in the middle of the chute, and the bottom of the shaft block 52 is horizontal and the upper surface of the disc 51 is two straight lines that will never intersect (as shown in a in FIG8). At this time, the welding head 7 will not change due to the shaft block 52; when the shaft block 52 rotates clockwise, one end of the shaft block 52 is tilted along the chute (as shown in b in FIG8), then the front end of the connection welding head 7 changes (downward or rightward); when the shaft block 52 rotates counterclockwise, the other end of the shaft block 52 is tilted along the chute (as shown in c in FIG8), then the front end of the connection welding head 7 changes (upward or leftward). This adjustment is applicable when the square block 523 or the trapezoidal block 521 is selected.
[0074] Therefore, further adjustments can be made according to different product conditions, so that the welding adjustment is more in line with actual needs. Further explanation: the top of the second connecting shaft 522 is fixedly connected to the lower surface of the trapezoidal block 521, and the bottom of the second connecting shaft 522 is provided with a steering shaft wheel to meet the need to maintain the direction of the shaft block 52 when the shaft block 52 is tilted; and after adjustment, the trapezoidal block 521 can be fixed to the disc 51 by bolts. Then, under the condition of customizing a full coverage of production product needs, prefabricated installation holes can be made on the disc 51 and the shaft block 52 in advance along the required adjustment direction to provide convenient adjustment.
[0075] 6, the surface of the shaft ball 53 is provided with a track, and the track matches the inner cavity at the bottom of the shaft block 52. When the shaft block 52 rotates, the inner cavity of the shaft block 52 moves along the track to increase the stability of the shaft block 52, maintain the overall force dispersion, and reduce the risk of concave bending.
[0076] Referring to Figures 1-3, the welding head 7 is arranged on the upper side of the height adjustment mechanism 5, which is an existing laser welding head. In order to promote the stability and fit of the connection between the two, a first connecting shaft 6 is arranged between the welding head 7 and the height adjustment mechanism 5. One side of the first connecting shaft 6 fits the shape of the body of the welding head 7, and the other side fits the shape of the height adjustment mechanism 5, so that the connection between the two is more stable. Secondly, in some special cases, the thickness of the first connecting shaft 6 can be limited to adapt to the required height of the equipment, and when height adjustment occurs in the production line, it can also be solved by replacing a more suitable first connecting shaft 6.
[0077] Based on the above, the operating steps of the utility model are as follows:
[0078] First, based on the situation of the rolling equipment production line, select the installation position of the first adjustment mechanism 2, and install it oppositely to the positioning die 1 on the opposite side. After the overall installation is stable, drive the first adjustment mechanism 2 and the second adjustment mechanism 3 to adjust the welding head 7 back and forth, left and right (or back and forth, up and down). Then, adjust the welding head 7 annularly through the angle adjustment mechanism 4, and based on the situation, adjust the welding head 7 up and down (or left and right) again through the height adjustment mechanism 5. After the adjustment, make specific fine-tuning based on the welding position until the requirements of the welding position are met. If there are changes during use, the welding head 7 can be installed by disassembling and setting a more suitable first connecting shaft 6, so that the welding head 7 is more in line with the actual requirements when starting the welding work.
[0079] The above description is only for explaining the present invention. It should be understood that the present invention is not limited to the above embodiments, and various equivalent forms that conform to the idea of the present invention are within the protection scope of the present invention.
