Description

Technical Field

[0001] The utility model belongs to the technical field of passenger car covering part processing, and particularly relates to a frame loading robot for a passenger car covering part stamping line. Background Technique

[0002] When installing an automobile frame, a frame loading robot for a passenger car covering part stamping line is required. The common frame loading robot for a passenger car covering part mainly consists of a six-axis robotic arm and a 3D vision positioning system. The robotic arm is driven to move through the 3D positioning system to grab the car frame parts, so as to replace manual labor. This can not only reduce the labor intensity of workers, but also improve the processing efficiency of passenger car covering parts, thereby realizing the efficient processing of passenger car covering parts.

[0003] However, the existing frame loading robots for passenger car covering parts generally require different mechanical claws when grabbing different car frames, and most mechanical claws and robotic arms are fixed by multiple bolts or other fixing parts. Therefore, when replacing the mechanical claws, workers need to disassemble the bolts or fixing parts multiple times, which is rather cumbersome to use and increases the replacement time.

[0004] To solve the above problems, a frame loading robot for a passenger car covering part stamping line is proposed in this application. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides a Figure 1 framing robot for a passenger car body panel stamping line as shown in

[0028] Controller 1, a rotating component 2 is arranged on the top of the controller 1, a first connecting arm 3 is arranged at one end of the rotating component 2, a rotatable second connecting arm 4 is arranged at the bottom of the first connecting arm 3, and a mechanical claw 5 for grasping materials is arranged at the bottom of the second connecting arm 4; wherein, the specific structures and working principles of the controller 1, the rotating component 2, the first connecting arm 3, the second connecting arm 4 and the mechanical claw 5 are all existing structures. For specific reference, please refer to the comparative document (publication number: CN217669451U, name: A robotic arm for automobile manufacturing), and no further elaboration will be made here.

[0029] As can be seen from the above, during use, first, the controller 1 is used to control the mechanical claw 5 to grasp the car frame, then the controller 1 is used to control the second connecting arm 4 to rotate. The second connecting arm 4 drives the mechanical claw 5 to rotate, enabling the controller 1 to control the rotating component 2 to rotate. The rotating component 2 drives the first connecting arm 3 to rotate, and the first connecting arm 3 drives the mechanical claw 5 to rotate through the second connecting arm 4. At the same time, the controller 1 controls the first connecting arm 3 to lift to a specified height through the rotating component 2, so that the mechanical claw 5 drives the car frame to move to a specified position and then installs it.

[0030] Reference Figures 1 - 5 As shown, a fixing device 6 is arranged between the second connecting arm 4 and the mechanical claw 5. The fixing device 6 includes a housing 601 fixed on the controller 1. A cavity is formed by the middle part of the housing 601 being recessed inward. A telescopic rod 602 is arranged in the cavity. Two rotatable clamping plates 604 are arranged on both sides of the telescopic rod 602. A transmission mechanism is arranged between the housing 601 and the clamping plate 604;

[0031] The transmission mechanism includes two positioning rods 603 fixed inside the cavity. The clamping plate 604 is provided with inclined slots adapted to the positioning rods 603, and the clamping plate 604 is sleeved outside the positioning rods 603. The bottom of the clamping plate 604 extends outside the cavity and contacts the mechanical claw 5. A cavity is provided in the upper half of the housing 601. The top of the telescopic rod 602 is fixed with a main inclined block 605. A movable sub-inclined block 606 is arranged in the cavity. The top of the main inclined block 605 is provided with a first inclined surface, and the bottom of the sub-inclined block 606 is provided with a second inclined surface adapted to the first inclined surface. A through hole adapted to the main inclined block 605 is provided in the cavity. The first inclined surface and the second inclined surface are in contact. A second spring is arranged between the main inclined block 605 and the cavity. One end of the sub-inclined block 606 is provided with a rotatable threaded rod 607. The top of the housing 601 is provided with a threaded hole adapted to the threaded rod 607. The end of the threaded rod 607 away from the sub-inclined block 606 penetrates through the housing 601 and is located outside the housing 601. Two positioning plates are symmetrically fixed on the upper half of the outer wall of the telescopic rod 602. A rotating shaft is arranged on the positioning plate. The top of the clamping plate 604 is provided with a groove adapted to the positioning plate. The clamping plate 604 is rotatably installed on the positioning plate through the rotating shaft and the groove. A transmission rod 608 is arranged inside the telescopic rod 602, and a groove is provided inside the telescopic rod 602. A first spring 610 is arranged in the groove. The top of the transmission rod 608 is fixed to the bottom of the main inclined block 605.

[0032] By adopting the above technical solutions:

[0033] During use, rotate the threaded rod 607. The threaded rod 607 mates with the threaded hole of the housing 601 to make the threaded rod 607 move horizontally. The threaded rod 607 drives the sub-inclined block 606 to move. The second inclined surface cooperates with the first inclined surface to separate the sub-inclined block 606 from the main inclined block 605. The second spring releases elastic force to drive the main inclined block 605 to move downward. The main inclined block 605 drives the transmission rod 608 to move downward. The first spring 610 releases elastic force to drive the telescopic rod 602 to move downward. The telescopic rod 602 drives the clamping plate to move downward. The clamping plate drives the clamping plate 604 to move downward, so that the positioning rod 603 moves along the inclined slot of the clamping plate 604. The inclined slot limits the clamping plate 604, so that the clamping plate 604 rotates around the rotating shaft, and the bottom of the clamping plate 604 contacts the bottom of the telescopic rod 602, separating the clamping plate 604 from the mechanical claw 5, thus facilitating people to replace the mechanical claw 5.

[0034] In addition, referring to Figures 3 - 5 As shown, a threaded portion is provided at the bottom of the transmission rod 608, and two nuts 609 are screwed on the threaded portion.

[0035] By adopting the above technical solutions:

[0036] During use, rotate the nut 609 to engage the nut 609 with the threaded portion of the transmission rod 608, separate the nut 609 from the transmission rod 608, and pull the telescopic rod 602 to separate the telescopic rod 602 from the transmission rod 608, thereby facilitating the replacement of the first spring 610 by people and further improving the convenience of the device.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
