Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing technology, and more specifically, it relates to a push-tube type rear support mechanism. Background Technology

[0002] The push-tube type rear support mechanism uses the push tube as the core transmission component. The linear extension and retraction motion of the push tube directly acts on the rear support component, avoiding the wear problem at the hinge of the traditional linkage and greatly improving the accuracy and stability of the pushing process. At the same time, the push tube structure is compact and occupies little space. Compared with the gear and rack structure, it is less susceptible to interference from external impurities, effectively improving the reliability and durability of the system. However, since the traditional pushing method uses a passive rocker arm, it is limited by the angle, which restricts its formation. Therefore, a push-tube type rear support mechanism is needed to facilitate the processing of workpieces. Utility Model Content

[0006] Preferably, the bottom support frame is configured as a platform structure; the side support frame is configured as a platform structure; and the mounting housing is provided with shaft holes.

[0007] Preferably, a transmission assembly is rotatably connected to the mounting frame; a drive motor is fixedly connected to the top of the mounting frame; the motor shaft of the drive motor is connected to a pulley, and the pulley of the drive motor is kept connected to the transmission assembly on the mounting frame via a belt; the transmission pulley is kept connected to the transmission assembly on the mounting frame via a belt.

[0008] Preferably, the displacement slider is slidably connected inside the mounting housing.

[0009] Preferably, the two sets of guide rods are fixedly connected to the inner side of the mounting housing.

[0010] Preferably, the pusher assembly is slidably connected inside the mounting housing.

[0011] The push-tube type rear support mechanism proposed in this utility model has the following beneficial effects:

[0012] 1. The transmission mechanism consisting of crankshaft, connecting rod, displacement slider and impact connecting rod can efficiently convert the circular motion of crankshaft into the linear reciprocating motion of pusher assembly, so that pusher assembly pushes workpiece according to set frequency and stroke with high precision. Through impact connecting rod, the mechanism stroke is longer. By adjusting the speed of drive motor, the working frequency of pusher assembly can be flexibly changed to adapt to different production rhythms and pusher requirements, which significantly improves work efficiency.
