Description

Technical Field

[0001] The utility model relates to the technical field of I-beam web punching machines, in particular to a tugboat assembly of the I-beam web punching machine. Background Art

[0002] The tugboat assembly is a device that uses a shaft fixedly connected to the inner side of a fixed bracket as the central axis of a rotating wheel to provide support for the transported material, and reduces the friction loss of the transported material by rotating, thereby increasing the transmission rate of the transported material;

[0003] In the process of using a tugboat assembly to support and transport the curved I-beam processed by a punching machine, since the curved I-beam has a certain curvature, in the process of using a rotating wheel to support and transport it, the moving trajectory of the curved I-beam is curved, and the supporting rotating wheel arranged parallel to the outside of the fixed shaft is not convenient for the curved I-beam to rotate smoothly during its side movement, which can easily cause the rotating wheel supporting the curved I-beam to get stuck due to the increased friction with the fixed shaft, affecting the movement and transportation of the curved I-beam. In addition, it is not convenient to adjust the distance between the tugboats when transporting I-beams of different thicknesses, and the model range suitable for transporting I-beams is relatively small. Therefore, in view of the above problems, a tugboat assembly of an I-beam web punching machine is proposed. Utility Model Content

[0004] The utility model aims to provide a tug wheel assembly of an I-beam web punching machine to solve the problems that a supporting rotating wheel arranged in parallel on the outer side of a fixed shaft is not convenient for the arc-shaped I-beam to rotate smoothly during its lateral movement, which easily leads to the rotating wheel supporting the arc-shaped I-beam getting stuck due to the increased friction with the fixed shaft, and it is inconvenient to adjust the distance between the tug wheels when transporting I-beams of different thicknesses.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The cam is an axially-coupled device for engaging with the guide wheel assembly and the guide wheel assembly is actuated by a threaded rod, and the guide wheel is engaged with the guide wheel on the cam side.

[0007] Preferably, there are two tugboat seats, which are symmetrically arranged on the same vertical line inside the tugboat chassis. The tugboat seat inside the upper end of the tugboat chassis is restricted and fixed by four bolts on the inner side of the tugboat seat and four nuts on the outer side of the upper end of the tugboat chassis, and the tugboat seat inside the lower end of the tugboat chassis is fixed and restricted by four screws and four threaded holes opened on the inner side of the bottom of the tugboat chassis.

[0008] Preferably, the internal threaded tube is fixed to the upper end of the tugboat chassis, the limit plate is in close contact with the inner side of the tugboat seat at the inner upper end of the tugboat chassis, and the rubber spring slidably connected to the internal threaded tube and the outer side of the bolt is in the same horizontal plane and parallel to each other.

[0009] Preferably, two bearings arranged parallel to each other on the outside of the pin shaft are fixedly connected by a second spacer ring, and the first spacer rings to which the two bearings fixedly connected on the outside of the pin shaft are respectively fixedly connected are tightly attached to two symmetrical inner sides of the tugboat seat.

[0010] Preferably, the hole retaining spring is arranged on the outside of the first spacer ring, and the hole retaining spring is tightly attached to the side of the bearing away from the center of the tugboat seat. The outer diameter of the hole retaining spring is larger than the maximum inner diameter of the tugboat, and the inner diameter of the hole retaining spring is smaller than the maximum outer diameter of the bearing. The maximum inner diameter of the tugboat is the same as the maximum outer diameter of the bearing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, by arranging an adjusting screw rod, an internal threaded tube, a rubber spring, a bolt, a bearing, a tugboat, a first spacer ring, a second spacer ring and a hole retaining spring, a combination of a bolt and a nut can fix and stably restrict a tugboat seat to the inner upper end of a tugboat chassis, and make the tugboat seat keep a certain distance from the upper end of the tugboat chassis, so that the adjusting screw rod inside the internal threaded tube can be rotated so that the limit plate can adjust the straight-line distance between the tugboat seat at the inner upper end of the tugboat chassis and the tugboat seat at the inner bottom of the tugboat chassis, and the tugboat is restricted to the outer side of the bearing fixedly connected to the outer side of the pin shaft by using the hole retaining spring, so that while ensuring that the tugboat has good rotation performance on the outer side of the bearing, the bearing itself has good rotation performance, which can effectively enhance the smooth movement and transportation of the arc I-beam on the tugboat assembly, and increase the range of the tugboat assembly for transporting I-beams of different thicknesses, thereby improving the practical significance of the tugboat assembly.
