Technical Field
[0001] The utility model relates to the field of manipulator sheet metal processing equipment, and particularly relates to a positioning and clamping mechanism for punching a connecting piece of a manipulator. Background Art
[0002] A manipulator is an automatic operation device that can imitate some action functions of human hands and arms and is used to grab, transport objects or operate tools according to a fixed program. Manipulators are widely used in automated production lines and can effectively improve the production quality and production efficiency of products.
[0003] The connecting piece is one of the parts that make up the manipulator. The connecting piece is a kind of rectangular plate part and needs to be drilled during the processing. Since the thickness of the connecting piece is small, in order to avoid deformation during processing, it is necessary to support the connecting piece during punching. Moreover, the connecting piece has various specifications, the lengths of different specifications of connecting pieces are different, and the punching positions are different. Therefore, a positioning and clamping mechanism for punching a connecting piece of a manipulator is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a positioning and clamping mechanism for punching a connecting piece of a manipulator, which can adapt to the positioning, clamping and support during punching of connecting pieces of different specifications, prevent deformation during punching, and can automatically unload the connecting piece after processing.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions: a positioning and clamping mechanism for punching a connecting piece of a manipulator, including a base. A double-threaded screw rod and a discharging cylinder are arranged on one side of the base. Two positioning seats are slidably connected to the other side of the base. The two positioning seats are respectively connected to the two threaded segments of the double-threaded screw rod. A seat plate is fixedly connected to the positioning seat. A pressing cylinder is fixedly connected to the seat plate. The piston rod of the pressing cylinder passes through the seat plate and is fixedly connected to a pressing plate. A chute is opened on the lower side of the base. A support seat is slidably connected to the chute. A让位孔 (releasing hole) is opened on the support seat. The support seat is fixedly connected to the base through a screw rod. A push fork is fixedly connected to the piston rod of the discharging cylinder.
[0006] [[ID=**22**]]Further, the double-threaded screw rod is rotationally connected to the base, and the discharging cylinder is fixedly connected to the base.
[0007] [[ID=**25**]]Further, the positioning seat is L-shaped, and the pressing plate is located between the seat plate and the positioning seat.
[0008] [[ID=**28**]]Further, the push fork is C-shaped, the push fork is located between the two positioning seats, and the push fork is arranged in a staggered manner with the support seat and the positioning seat.
[0009] It should be noted that there is a Chinese term "让位孔" in the original text which is translated as "releasing hole" here tentatively. If there is a more accurate English term for this in the context of mechanical engineering, it can be adjusted accordingly.The beneficial effects of the utility model are: through the coordinated use of the double-threaded screw, the unloading cylinder, the positioning seat, and the clamping cylinder, it can adapt to the positioning, clamping and support when punching connecting pieces of different specifications, prevent deformation during punching, and can automatically unload the connecting pieces after processing is completed.

[0016] The double-threaded screw rod 2 is rotatably connected to the base 1 . The rotation of the double-threaded screw rod 2 is used to adjust the distance between the two positioning seats 4 to adapt to the positioning and placement of connecting pieces of different specifications. The unloading cylinder 3 is fixedly connected to the base 1 .
[0017] The positioning seat 4 is L-shaped, and the pressing plate 403 is located between the seat plate 401 and the positioning seat 4. The pressing plate 403 is driven to rise and fall by the pressing cylinder 402 to achieve the tightening and loosening of the connecting piece.
