Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 5, the structure of the clamping fixture for laser welding of the B-pillar of the vehicle roof provided by the invention is schematically illustrated. As is well known, the B-pillar of the roof includes a frame, a B-pillar disposed on one side of the frame, and two cross members disposed on the frame. The two cross beams and the B column are respectively positioned on two sides of the frame. The clamping fixture for the B-pillar laser welding of the roof comprises a base 10, an abutting rod 20 arranged on the base 10, an upper abutting mechanism 30 arranged on the base 10, and a swinging abutting mechanism 40 arranged on the base 10. It is contemplated that the vehicle roof B-pillar laser welding clamping fixture may further include other functional modules, such as assembly components, mounting components, electrical connection components, etc., which are well known to those skilled in the art and will not be described herein.
The base 10 is used for mounting and fixing the abutting rod 20, the upper abutting mechanism 30 and the swinging abutting mechanism, and is also used for fixing the clamping fixture on the welding table, which is not described in detail herein. The base 10 includes a post 11. The purpose of the prop 11 will be described in detail below in connection with the abutting rod 20 and the upper abutting mechanism.
The abutting rod 20 is disposed at the top end of the pillar 11 and includes a first abutting surface 21, a second abutting surface 22, and a third abutting surface 23. The shapes of the first, second, and third abutting surfaces 21, 22, and 23 may be determined according to actual needs, and are all disposed toward the upper abutting mechanism 30, which is not described herein again. The abutting rod 20 is fixed and is used for cooperating with the abutting work of the upper abutting mechanism 30.
The upper propping mechanism 30 is arranged on the side of the pillar 11 of the base 10 and comprises a linear driving seat 31 arranged on the pillar 11, a chicken head 32 arranged on the linear driving seat 31, a transition seat 33 arranged on the chicken head 32, and an upper propping rod 34 arranged on the transition seat 33. The linear driving seat 31 may be a cylinder, which can drive the chicken head 32 to reciprocate. The chicken head 32 is disposed on the linear driving seat 31 and can reciprocate under the driving of the linear driving seat 31. The transition seat 33 is fixedly arranged on the chicken head 32, and may be in a right-angle shape to connect the chicken head 32 with the upper propping rod 34. The upper abutting rod 34 is fixedly disposed on the transition 33 and includes a fourth abutting surface 341, a fifth abutting surface 342 spaced apart from the fourth abutting surface 341, and a sixth abutting surface 343 spaced apart from the fifth abutting surface 342. The shapes of the fourth, fifth and sixth butting faces 341, 342, 343 can be designed according to actual needs, and will not be described in detail here. However, in practical applications, the fourth, fifth and sixth abutting surfaces 341, 342 and 343 are respectively opposite to the first, second and third abutting surfaces 21, 22 and 23 of the retaining bar 20 for clamping the frame and the B-pillar. When the chicken head 32 moves under the driving of the linear driving seat 31, the fourth, fifth and sixth abutting surfaces 341, 342 and 343 abut against the first, second and third abutting surfaces 21, 22 and 23 respectively to fix the corresponding parts of the roof when in operation. For the purpose of buffering and avoiding the surface of the car roof from being damaged during clamping, buffering cushions can be further arranged between the chicken head 32 and the transition seat 33 and between the transition seat 33 and the upper abutting rod 34 to buffer the impact from the upper abutting rod 34 and avoid damaging the workpiece.
The swing abutting mechanism 40 comprises a swing frame 41 arranged on the base 10, a swing driving mechanism 42 arranged between the swing frame 41 and the base 10, an abutting rod 43 arranged on the swing driving mechanism 42, two beam abutting mechanisms 44 arranged on the swing frame 41 and positioned at two sides of the abutting rod 43, and a beam positioning mechanism 45 arranged right below the abutting rod 43.
The swing frame 41 includes two L-shaped swing arms 411 pivotally connected to the base 10, and a bracket 412 mounted on the two L-shaped swing arms 411. It is conceivable that two vertical plates are required for the base 10 to pivot the L-shaped swing arm 411, and then the two vertical plates are connected in series with the two L-shaped swing arms 411 through a pivot shaft, so that the L-shaped swing arms 411 can rotate around the pivot shaft. It is conceivable that one side of the L-shaped swing arm 411 is disposed apart from the base 10, not directly abutting on the base 10, so that the L-shaped swing arm 411 can be rotated. The bracket 412 is fixedly arranged on the other side of the L-shaped rocker arm 411, so that the position relation between the two L-shaped rocker arms 411 is fixed. In practical operation, when one side of the L-shaped rocker 411 abuts against the base 10, the first, second, and third abutting surfaces 21, 22, and 23 abut against the fourth, fifth, and sixth abutting surfaces 341, 342, and 343, respectively, that is, the frame and the B-pillar are clamped.
The swing driving mechanism 42 includes a driving plate 421 disposed on the bracket 412, and a driving device 422 for driving the driving plate 421 to rotate. The driving plate 421 is fixed on the bracket 412, and is aligned with the upper abutting rod 34. The driving device 422 is a cylinder, which is disposed on the base 10, and an output end of the cylinder is pivotally connected to the driving plate 421, so that when the output end of the cylinder reciprocates, the driving plate 421 and the swing frame 41 can be driven to rotate.
The abutting lever 43 is provided on the driving plate 421 and extends toward the upper abutting mechanism 20. The abutment lever 43 comprises a U-shaped head 431 and two abutment surfaces 432 which are arranged on the U-shaped head 431, respectively. When one side of the L-shaped rocker 411 abuts against the base 10, that is, when the upper abutting mechanism 30 and the abutting rod 20 clamp the relative position between the B-pillar and the frame, the abutting portion 432 of the abutting rod 43 abuts against the B-pillar to support the B-pillar, and the relative position between the B-pillar and the frame can be maintained. The abutting rod 20 is inserted into the U-shaped head 431, so that the structural volume of the whole clamping fixture can be reduced, and the clamping fixture is more compact.
The beam abutting mechanism 44 includes a lower rod 441 disposed on the support 412 of the swing frame 41, and a movable abutting mechanism 442 disposed on the support 412 of the swing frame 41. The lower prop rod 441 is perpendicular to the plane of the base 10, i.e. parallel to the moving direction of the linear driving seat 31. The movable abutting mechanism 442 includes a mounting frame 443 disposed on the swing frame 41, a link mechanism 444 pivotally connected to the mounting frame 443, an upper prop 445 disposed on the link mechanism 444, and a driver 446 for driving the link mechanism 444 to move. The mounting frame 443 is a frame-shaped structure for accommodating not only the link mechanism 444 but also for mounting a pivot for rotating the link mechanism 444. The link mechanism 444 includes a right-angle link 4441 pivotally connected to the mounting frame 443, a pull rod 4442 having one end fixedly connected to a corner of the right-angle link 4441, and a driving rod 4443 pivotally connected to the other end of the pull rod 4442. The end of one side of the right angle link 4441 is pivotally connected to the mounting frame 443 so that the other side of the right angle link 4441 can move up and down as the right angle link 4441 pivots. One end of the pull rod 442 is fixed to a corner of the right angle link 4441, so that the right angle link 4441 can be driven to rotate around its pivot when the pull rod 442 is pulled up and down. The other end of the pull rod 4442 is pivoted to the driving rod 4443, and the driving rod 443 is driven to rotate by the driving of the driver 446. When the pull rod 442 rotates, the right-angle link 4441 can be driven to rotate. The upper post 445 is disposed on the right-angle shaped connecting rod 4441 and includes a seventh abutting surface 4451. In order to make the seventh abutting surface 4451 abut against the lower abutting rod 441, the upper ejector rod 445 has a U shape, and the seventh abutting surface 4451 is disposed at the end of the U-shaped structure. By providing the U-shaped structure, the lower post rod 441 and the movable abutting mechanism 442 can be disposed on the bracket 412 of the swing frame 41, so that the structural volume of the clamping fixture can be reduced, and the structure thereof is compact.
The beam positioning mechanism 45 includes a reciprocating driving mechanism 451 provided on the support 411 of the rocking beam 41, a support plate 452 mounted on the reciprocating driving mechanism 451, and two positioning pins 453 provided at intervals on the support plate 452. The reciprocating drive mechanism 451 may be a pneumatic cylinder, and will not be described in detail herein. The support plate 452 is disposed at the output end of the reciprocating drive mechanism 451, and the moving direction thereof may be parallel to the driving direction of the linear drive base 31, i.e., when clamping and positioning a workpiece. Two positioning insertion rods 453 are fixed on the support plate 452 and located on both sides of the abutting rod 43 to insert and position two works, i.e., a cross beam and a frame.
When the linear driving device works, a vehicle frame is firstly placed on the dummy ejection rod 20, the first, second and third ejection surfaces 21, 22 and 23 of the dummy ejection rod 20 are ejected to corresponding positions of the vehicle frame, then a B column is placed on corresponding positions of the vehicle frame, and finally the linear driving seat 31 is opened to eject the fourth, fifth and sixth ejection surfaces 341, 342 and 343 of the upper ejection rod 34 to the B column. Then, the driving device 422 is turned on, so that the abutting surface 432 of the abutting rod 43 abuts against the B-pillar, thereby fixing the relative position of the B-pillar and the roof frame.
A cross member is then placed in the corresponding position on the frame and the positioning pins 453 of the cross member positioning mechanism 45 are inserted into the corresponding insertion holes of the cross member and the frame, which positions the cross member and the frame. Then the corresponding position of the cross beam and the frame is inserted between the seventh butting surface 4451 of the lower ejector rod 441 and the upper ejector rod 445, and finally the driver 446 is opened to make the lower ejector rod 441 and the seventh butting surface 4451 butt against and fix the cross beam and the frame.
Compared with the prior art, the vehicle roof B-pillar laser welding clamping fixture provided by the invention clamps the vehicle frame and the B-pillar together through the abutting rod 20 and the upper abutting mechanism 30, and then rotates the swinging abutting mechanism 40 to enable the abutting rod 43 to abut against the B-pillar so as to fix the relative position of the B-pillar and the vehicle frame. When the leaning rod 43 is leaned against the B column, a cross beam is arranged on the frame, the relative position between the cross beam and the frame is fixed through the cross beam positioning mechanism 45, then the cross beam and the frame are clamped through the cross beam leaning mechanism 44, and the other cross beam can be clamped on the roof frame by repeating the steps. Through the structural design of the virtual abutting rod 20 and the upper abutting mechanism 30, especially through the structural design of the swinging abutting mechanism 40, the laser welding clamping fixture is compact in structure, and the clamping effect is good under the clamping of the abutting rod 43 and the beam positioning mechanism 45. In addition, the swing driving mechanism 42, the beam abutting mechanism 44 and the beam positioning mechanism 45 are driven by different driving devices so as to ensure the clamping stability of the beam positioning mechanism, poor welding caused by looseness during welding is avoided, and the B column, the roof frame and the two beams can be clamped by one laser welding clamping fixture for the B column of the roof, so that the laser welding efficiency can be improved.
