As shown in fig. 1 to fig. 3, a laser welding tooling device provided in an embodiment of the present invention includes: the device comprises a positioning mechanism 1, an end face pressing mechanism 2, an inner support positioning pressing mechanism 3 and a spinning mechanism 4;
the positioning mechanism 1 comprises a guide post 11, a positioning piece 12 and a supporting seat 13; the guide post 11 and the positioning piece 12 are mounted (mounted by screws and the like) on the support base 13; the positioning piece 12 is used for positioning a first workpiece 101 to be welded; as can be appreciated, the positioning member 12 is used for positioning the first workpiece 101 on the supporting seat 13; preferably, the positioning member 12 is a positioning pin, and the positioning member 12 may be designed in a plurality according to actual requirements. The guide post 11 may be a separate structural member mounted on the support base 13 by a process such as screwing, welding, or the like, or may be a structural member integrally formed on the support base 13.
The end face pressing mechanism 2 is mounted on the supporting seat 13, and the end face pressing mechanism 2 is used for pressing the positioned first workpiece 101 on the supporting seat 13;
preferably, the guide post 11 is subjected to surface hardening treatment, so that the wear resistance of the guide post 11 is improved, and the service life of the laser welding tool equipment is prolonged.
The inner support positioning and pressing mechanism 3 comprises a side positioning block 31 and a limiting block copying limiting block 32 connected with the side positioning block 31, wherein a first positioning through hole 311 is formed in the side positioning block 31, and a second positioning through hole 321 communicated with the first positioning through hole 311 is formed in the copying limiting block 32; the second workpiece 102 to be welded is sleeved on the side positioning block 31 and abutted against the profiling limiting block 32, and the guide column 11 passes through the first positioning through hole 311 and the second positioning through hole 321 to position the second workpiece 102; it can be understood that the profile stopper 32 may be an integrally formed structure of the side positioning block 31, or may be a separate structural member connected to the side positioning block 31 by means of screw connection, welding, or the like; the side positioning block 31 is designed according to the shape of the workpiece through hole of the second workpiece 102, and is a precise contact surface of the second workpiece 102.
When a pressing instruction of a second workpiece 102 is received, the spinning mechanism 4 presses one end of the profiling limiting block 32, which is far away from the second workpiece 102, so as to drive the profiling limiting block 32, the side positioning block 31 and the second workpiece 102 to move towards the first workpiece 101 along the guide column 11 until a second welding edge of the second workpiece 102 is pressed against a first welding edge of the first workpiece 101. Specifically, when the inner support positioning and pressing mechanism 3 passes through the first positioning through hole 311 and the second positioning through hole 321 through the guide post 11, a compression space is left between the lower surface of the inner support positioning and pressing mechanism 3 and the upper surface of the positioning mechanism 1, the rotary telescopic mechanism drives the profiling limiting block 32 to move downwards, so that the second workpiece 102 is pressed on the first workpiece 101 through the side positioning block 31, and the first welding edge of the first workpiece 101 is aligned with the second welding edge of the second workpiece 102; it can be understood that the profile limiting stopper 32 cannot pass through the workpiece through hole of the second workpiece 102, the side positioning block 31 can pass through the workpiece through hole of the second workpiece 102, and the height of the side positioning block 31 is greater than the height of the second workpiece 102, so that the rotating expansion element 41 can drive the second workpiece 102 to press against the first workpiece 101 when driving the profile limiting stopper 32 to move down.
It is understood that the portion where the first workpiece 101 and the second workpiece 102 are connected to each other is a laser welding area of the laser welding tooling equipment, that is, the first welding edge and the second welding edge are laser welding areas of the laser welding tooling equipment, and preferably, the first workpiece 101 and the second workpiece 102 include, but are not limited to, two portions that need to be welded to each other in the energy absorption box of the automobile impact beam shown in fig. 1.
In the invention, firstly, the first workpiece 101 is accurately installed on the supporting seat 13 through the positioning piece 12, then the first workpiece 101 is pressed on the supporting seat 13 through the end face pressing mechanism 2, the second workpiece 102 is installed on the inner support positioning pressing mechanism 3 through the adaptive connection of the side positioning block 31 and the second workpiece 102, the second workpiece 102 is installed on the end face pressing mechanism 2, the second workpiece 102 is pressed on the second workpiece 102 through the spinning mechanism 4, and the first welding edge of the first workpiece 101 is aligned with the second welding edge of the second workpiece 102, so that the relative displacement between the first workpiece 101 and the second workpiece 102 is avoided in the laser welding process, and the laser welding quality of the laser welding tooling equipment is improved, the laser welding precision and the welding strength of the first workpiece 101 and the second workpiece 102 are improved, and cracks of the welding seam of the first workpiece 101 and the second workpiece 102 are avoided; and the side positioning block 31 is designed according to the workpiece shape matching of the second workpiece 102, so that the second workpiece 102 can be accurately installed on the inner support positioning and pressing mechanism 3, and the deformation of the second workpiece 102 in the laser welding process is reduced.
In an embodiment, as shown in fig. 1 and 10, the laser welding tooling equipment further includes a movement monitoring mechanism 5 for detecting whether the second workpiece 102 is mounted in place; the movement monitoring mechanism 5 comprises a first telescopic piece 51 and a detection rod 52 arranged on the first telescopic piece 51; a workpiece hole 1021 is formed in the second workpiece 102; it will be appreciated that the first telescopic member 51 may be a linear driving member such as a linear motor, a hydraulic cylinder, a pneumatic cylinder, a rack and pinion driving mechanism, etc.
When the first telescopic piece 51 drives the detection rod 52 to extend to a preset length; if the detection rod 52 extends into the workpiece hole 1021, it is confirmed that the second workpiece 102 is installed in place; if the detection rod 52 abuts against the outer wall of the second workpiece 102, it is confirmed that the second workpiece 102 is not mounted in place. It can be understood that the preset length is a length of the first telescopic member 51 carrying the detection rod 52 forward, and when the detection rod 52 moves forward by the preset length, only two states of the front end of the detection rod 52 are possible: extend into the workpiece aperture 1021 or contact the outer wall of the second workpiece 102; further, in order to improve the quality of the laser welding between the first workpiece 101 and the second workpiece 102, the second workpiece 102 needs to be accurately mounted on the side positioning block 31 of the inner support positioning mechanism 1, the first telescopic member 51 can drive the detection rod 52 to move towards the second workpiece 102, and when the detection rod 52 extends into the workpiece hole 1021 and does not contact with the outer wall of the second workpiece 102 (i.e. the detection rod 52 detects the workpiece hole 1021), it indicates that the second workpiece 102 is accurately mounted on the side positioning block 31; when the detecting rod 52 does not extend into the workpiece hole 1021 but contacts the outer wall of the second workpiece 102, it indicates that the second workpiece 102 is not precisely mounted on the side positioning block 31, and the second workpiece 102 needs to be mounted again. In summary, through the design of the movement monitoring mechanism 5, the error-proofing performance of the laser welding tooling equipment is improved, and the laser welding quality of the first workpiece 101 and the second workpiece 102 is improved.
Preferably, as shown in fig. 10, the movement monitoring mechanism 5 further includes a return spring 53 connected to an end of the detection lever 52 remote from the second workpiece 102, and a detection sensor 54 communicatively connected to the detection lever 52; when the first telescopic piece 51 drives the detection rod 52 to move forward and contact with the outer wall of the second workpiece 102, the detection sensor 54 sends a signal that the installation is not in place to a control module of the laser welding tooling equipment, and the control module controls the laser 7 not to perform laser processing on the first workpiece 101 and the second workpiece 102; when the detection rod 52 extends into the workpiece hole 1021 without abutting against the outer wall of the second workpiece 102, the detection sensor 54 will send a signal of being installed in place to the control module, and the control module will control the laser 7 to perform laser processing on the first workpiece 101 and the second workpiece 102; the return spring 53 is provided to assist the detection rod 52 to retract toward the end away from the second workpiece 102 when the detection rod 52 abuts against the outer wall of the second workpiece 102, so as to avoid the impact between the detection rod 52 and the second workpiece 102, that is, improve the laser welding quality of the second workpiece 102, and prolong the service life of the detection rod 52.
In an embodiment, as shown in fig. 3, the laser welding tooling equipment further includes a rotary displacement mechanism 6 for driving the supporting seat 13 to rotate; the rotary displacement mechanism 6 comprises a bottom plate 61, a rotary driving piece 62 and a rotary drag chain 63 for accommodating pipelines; the rotary driving piece 62 and the rotary drag chain 63 are both mounted (mounted by means of screw connection, welding and the like) on the bottom plate 61; the support base 13 is mounted (by means of screw connection, welding, etc.) on the rotary drive 62. Preferably, the rotary drive 62 is a torque motor. It can be understood that the pipelines comprise the pipeline of the end face pressing mechanism 2, the pipeline of the inner support positioning pressing mechanism 3, the pipeline of the spinning mechanism 4 and the pipeline of the positioning mechanism 1, since the supporting seat 13 is installed on the rotary driving member 62, and the positioning mechanism 1, the end face pressing mechanism 2, the inner support positioning pressing mechanism 3 and the spinning mechanism 4 are all installed on the supporting seat 13, the rotary driving member 62 will drive the positioning mechanism 1, the end face pressing mechanism 2, the inner support positioning pressing mechanism 3 and the spinning mechanism 4 to rotate through the supporting seat 13, the rotary drag chain 63 can ensure that the supporting seat 13 drives the rotary drag chain 63 to rotate in the process of rotating the rotary driving piece 62, so as to ensure that the pipelines are not mutually wound and rubbed; therefore, due to the design of the rotary drag chain 63, the abrasion of a pipeline is effectively avoided, and the service life of the laser welding tool equipment is prolonged.
In summary, the spinning mechanism 4 can drive the positioning mechanism 1, the end face pressing mechanism 2, the inner support positioning pressing mechanism 3, the spinning mechanism 4, the first workpiece 101, and the second workpiece 102 to rotate, so that laser welding of the first workpiece 101 and the second workpiece 102 can be completed under the condition of one-time clamping, the laser welding efficiency of the laser welding tooling equipment is improved, batch production of the first workpiece 101 and the second workpiece 102 is facilitated, and the laser welding cost of the first workpiece 101 and the second workpiece 102 is reduced.
In one embodiment, as shown in fig. 9, the rotary shift mechanism 6 further includes a limiting block 64 for limiting the moving position of the rotary drag chain 63 on the bottom plate 61 and a sensing switch 65 for monitoring whether the rotary driving member 62 is rotated to the right position; the inductive switch 65 and the limiting block 64 are both installed on the bottom plate 61. It can be understood that the limiting block 64 and the inductive switch 65 can be provided in plural according to actual requirements, and are disposed on a side of the rotating drag chain 63 away from the rotating driving member 62. It can be understood that the inductive switch 65 is used for monitoring and feeding back the rotation arrival condition of the rotary driving element 62 in real time, when the rotary driving element 62 fails or the rotary driving element 62 does not rotate in place, the inductive switch 65 sends a control signal to the control module, and the control module controls the laser welding tooling equipment to perform power-off protection, so that the inductive switch 65 plays a role of hard software limiting; in addition, the limiting block 64 is disposed on the bottom plate 61 for limiting the moving position of the rotating drag chain 63 on the bottom plate 61, and when the supporting seat 13 drives the rotating drag chain 63 to rotate beyond the moving position thereof, the rotating drag chain 63 will contact with the limiting block 64, so that the limiting block 64 functions as a mechanical hard limiting block, and the rotating drag chain 63 can be prevented from exceeding the moving position thereof on the bottom plate 61. To sum up, the design of the limiting block 64 and the inductive switch 65 plays a role in double protection of the pipeline, so that the safety of the laser welding tool equipment is improved, and the service life of the laser welding tool equipment is prolonged.
