Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a clamping device for large sheet metal parts with dual workstations. Background Technology

[0002] The car body frame, such as longitudinal beams and cross beams, is usually made of high-strength sheet metal parts. These sheet metal parts are formed by bending, stamping and other processes and assembled into a sturdy frame to provide support and strength for the entire car body, protect the safety of the occupants, and withstand various loads and impacts during vehicle operation.

[0003] Given the complexity and precision of automotive body structures, large sheet metal parts often cannot be directly formed in one step. Instead, several smaller sheet metal parts need to be precisely spliced ​​together, and then welded or assembled to firmly bond them together, ultimately achieving the dimensional and strength standards required for the large sheet metal part. After the smaller sheet metal parts are placed in the designated positions, effective fixing measures must be used to secure them firmly to prevent displacement or shaking during welding or assembly, which could affect the quality of the process. In existing technologies, each small sheet metal part is equipped with a matching fixing fixture. On the one hand, due to the complexity of the vehicle body structure and the large number of small sheet metal parts required, this directly leads to a sharp increase in the number of fixing fixtures used on the production line. On the other hand, workers need to install and adjust the corresponding fixing fixture for each small sheet metal part one by one, a time-consuming and labor-intensive process that greatly slows down the overall production pace.

[0004] Therefore, those skilled in the art are dedicated to developing a clamping device for large sheet metal parts with dual workstations, which can quickly and securely clamp multiple small sheet metal parts and improve the efficiency of sheet metal assembly. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, a clamping device for large sheet metal parts with dual workstations includes a base 510. Height adjustment components 511 are also installed at the four corners of the bottom of the base 510. The height adjustment components 511 can be composed of a fixing nut, an adjusting screw and a support cup group. By adjusting the height of each corner, it can adapt to different ground conditions and keep the plane of the base 510 horizontal.

[0034] The first clamping assembly 520 and the second clamping assembly 530 are both mounted on the base 510, and the ends of the first clamping assembly 520 and the second clamping assembly 530 are connected by a linkage assembly 540. The first clamping assembly 520 and the second clamping assembly 530 both have clamping arms 550 for pressing against sheet metal parts. When the telescopic force-applying assembly 560 is activated, the linkage assembly 540 can be used to realize the synchronous action of the two clamping assemblies and drive the clamping arms 550 to rotate. The telescopic force-adding component 560 is installed at the ends of the first clamping component 520 and the second clamping component 530. The telescopic force-adding component 560 extends and retracts to drive the clamping arm 550 to rotate and press against the sheet metal part.

[0035] like Figure 1 , Figure 2As shown, in some embodiments, both the first clamping assembly 520 and the second clamping assembly 530 include a rotating column 521. The end of the rotating column 521 is mounted on the base 510 via a support seat 522, allowing the rotating column 521 to rotate stably under the support of the support seat 522 and bear the torque generated during clamping. The clamping arm 550 is vertically connected to the rotating column 521 to ensure efficient force transmission, allowing the clamping arm 550 to rotate smoothly and accurately under the drive of the rotating column 521. An adjusting rod 551 is installed on the clamping arm 550. The adjusting rod 551 can be a screw, which is installed on the clamping arm 550 through the cooperation of the screw and a locking nut. A rubber post 552 for abutting against the sheet metal part is installed at the end of the adjusting rod 551. When clamping sheet metal parts of different sizes and shapes, the length or position of the adjusting rod 551 can be adjusted to allow the rubber post 552 to accurately abut against the surface of the sheet metal part, and the rubber material can buffer the clamping force and prevent damage to the surface of the sheet metal part.

[0036] In another embodiment, the linkage assembly 540 includes a linkage seat 541, on which a rotating rod 542 is mounted via a support bearing. The support bearing reduces the friction of the rotating rod 542 during rotation, ensuring flexible rotation. Both ends of the rotating rod 542 extend beyond the linkage seat 541 and connect to the ends of the rotating column 521. When the telescopic force-applying assembly 560 actuates, causing the rotating column 521 of the second clamping assembly 530 to rotate, the rotating rod 542 can simultaneously drive the rotating column 521 of the first clamping assembly 520 to rotate, achieving simultaneous clamping at two stations.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the telescopic force-adding assembly 560 includes a telescopic cylinder 561, which is mounted on the base 510. The output end of the telescopic cylinder 561 is connected to a hinge assembly. The end of the rotating column 521 is equipped with a rotating block 523 for abutting against the hinge assembly. The telescopic cylinder 561 extends and retracts, causing the hinge assembly and the rotating block 523 to rotate, so that the clamping arm 550 rotates around the rotating column 521. Specifically, the hinge assembly includes a hinge post 562. One end of the hinge post 562 is hinged to the output end of the telescopic cylinder 561, allowing the hinge post 562 to swing within a certain angle range to adapt to the rotation trajectory of the clamping arm 550. The other end of the hinge post 562 is close to the rotating block 523. The middle part of the hinge post 562 is connected to one end of the hinge plate 563. The other end of the hinge plate 563 is hinged to the base 564. The base 564 is mounted on the telescopic cylinder 561. When the telescopic cylinder 561 extends or retracts, the hinge post 562 converts linear motion into rotation of the rotating post 521 by abutting against the rotating block 523, thereby driving the clamping arm 550 to move.

[0038] In this embodiment, a first position detection component 570 and a second position detection component 580 are also installed on the rotating column 521 to monitor the position of the clamping arm 550 in real time and provide feedback to the automated control system for precise control of the clamping process.

[0039] The first position detection component 570 includes a first photoelectric sensor 571. The detection end of the first photoelectric sensor 571 is horizontally set. A first detection block 572 for cooperating with the first photoelectric sensor 571 is installed on the rotating column 521. When the clamping arm 550 reaches the preset horizontal position, the first detection block 572 blocks or reflects light to the photoelectric sensor, triggering a corresponding signal.

[0040] Similarly, the second position detection component 580 includes a second photoelectric sensor 581. The detection end of the second photoelectric sensor 581 is vertically arranged. A second detection block 582 is installed on the rotating column 521 to cooperate with the second photoelectric sensor 581. This block is used to detect the position of the clamping arm 550 in the vertical direction, ensuring that the clamping arm 550 accurately completes the clamping action and improving the reliability and automation of the entire device.
