Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to a robot pneumatic fixture for wiring harness cable welding. Background Art

[0002] At present, in the large-scale use of robot equipment for automation during the welding of wire harnesses and cables, the improvement and optimization of the structure of the robot equipment itself must be carried out simultaneously to meet the ever-changing processing needs. For example, the patent document with application number 201921087858.0 proposes "a pneumatic clamp for a wire harness and cable welding robot, including: a mounting seat, a cylinder, a connecting plate, a guide rod, a sleeve, a connecting rod, a clamp, a connecting flange, an upper clamp, a lower clamp, a clamp, and a rubber pad". After specific implementation, "the utility model sets the clamp and the rubber pad in a V-shape when viewed from the side, which is convenient for the cooperation between the V-shaped clamp and the rubber pad to improve the stability of the ABS wire harness cable during clamping, and the rubber pad is used to protect the surface of the ABS wire harness cable."

[0003] However, in the actual processing process, the surface of the wire harness cable is smooth. Although the rubber pad provided in the above patent document can increase the friction of the wire harness cable in the V-shaped clamp, the increase range is limited. Moreover, as the diameter of the wire harness cable decreases, the effect of increasing the friction of the rubber pad will gradually decrease, and there are still limitations in practicality.

[0010] Selected, in order to further improve the stability of the reciprocating lifting of the composite transition curved plate and the top clamp frame plate, the number of the guide rods is three and they are distributed in a triangular shape between the composite transition curved plate and the top of the clamp base.

[0011] Preferably, auxiliary plates and pressure sensors are installed inside both sides of the top clamp frame plate, and clearance grooves are opened on the inner walls on both sides of the top clamp frame plate, and elastic sheets are nested in the two clearance grooves to provide structural deformation conditions for subsequent pressure detection.

[0012] Preferably, the inside of the two auxiliary plates are both provided with detection rods, and the detection rods include a T-shaped rod and a spring. The middle part of the T-shaped rod is clamped in the inside of the corresponding auxiliary plate, and the two ends of the spring are respectively fixedly connected to the surface of one end of the T-shaped rod and the surface of the auxiliary plate.

[0013] Preferably, both ends of the T-shaped rod are spherical structures to avoid scratches, and the two spherical structures are respectively connected to the pressure-sensitive surface of the pressure sensor and the surface of the elastic sheet.

[0014] Preferably, a protective frame is mounted on the outer side of the first meshing output component, and the top of the protective frame is in a movably connected state with the guide rod and the straight tooth plate. The protective frame is used to provide peripheral protection for the first meshing output component, thereby improving the safety of the overall device when in use.

[0015] Selectedly, the second meshing output component includes an L-shaped tooth plate, a second gear and a pneumatic push rod. The L-shaped tooth plate as the output structure of the second meshing output component is meshed with the bottom of the straight tooth plate for transmission.
