Description

Technical Field

[0001] This utility model relates to the technical field of material feeding, specifically a dual-channel automatic feeding mechanism. Background Technology

[0002] When assembling bearings, a retaining ring needs to be installed at the bottom of the bearing (see...). Figure 1 ), and composite gaskets (see Figure 2 The existing technology involves assembling the retainer into the bearing first, and then assembling the composite washer into the retainer. In practice, this requires two independent assembly stations during bearing assembly, resulting in a relatively large number of assembly stations and increasing the likelihood of defective products. Research has shown that assembling the composite washer and retainer directly before bearing assembly, and then assembling the composite together onto the bearing, would improve the assembly yield and reduce the number of stations in the bearing assembly equipment, thereby increasing production efficiency. Therefore, there is an urgent need to develop a mechanism that can directly assemble the composite washer onto the retainer before feeding it into the bearing. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a dual-channel automatic feeding mechanism that allows composite washers to be fed directly after the retaining ring is assembled, reducing the number of workstations in the bearing assembly equipment and thus improving the bearing assembly efficiency.

[0004] A dual-channel automatic feeding mechanism, characterized in that it comprises:

[0005] The first vibrating hopper includes a first hopper and a first flow channel, and a retaining ring is placed inside the first hopper;

[0006] The second vibrating hopper includes a second hopper and a second flow channel, and a composite gasket is placed inside the second hopper;

[0007] First linear discharge mechanism;

[0008] Second linear discharge mechanism;

[0009] The material mixing seat includes a feeding positioning block, a retaining ring guide block, a composite gasket pushing cylinder, a retaining ring guide block pushing cylinder, and a lifting and pressing cylinder. The feeding positioning block is provided with a contoured flow channel for placing a single composite gasket. The starting end of the contoured flow channel is the composite gasket feeding station, and the ending end is the composite feeding station. The composite gasket pushing cylinder drives the composite gasket located at the composite gasket feeding station to move to the lower layer of the composite feeding station. The retaining ring guide block is provided with a retaining ring positioning notch. The retaining ring guide block pushing cylinder drives the retaining ring in the retaining ring positioning notch to move linearly to the upper layer of the composite feeding station. The lifting and pressing cylinder lifts and pushes the composite gasket into the lower layer installation space of the retaining ring.

[0010] When the retaining ring is being fed, the first flow channel of the first vibrating hopper is connected to the retaining ring positioning notch of the retaining ring guide block through the first linear discharge mechanism;

[0011] When the composite gasket is being fed, the second flow channel of the second vibrating hopper is connected to the composite gasket feeding station of the feeding positioning block through the second linear discharge mechanism.

[0012] Its further features are:

[0013] The material mixing seat also includes a mounting frame. The composite gasket pusher cylinder is fixed on one side of the mounting frame, and the retaining ring guide block pusher cylinder is fixed on the other side of the mounting frame. The feeding positioning block is fixed inside the piston end of the composite gasket pusher cylinder. The piston end of the composite gasket pusher cylinder is provided with a push rod, and the push rod extends into the contoured flow channel.

[0014] The piston output end of the retaining ring guide block pusher cylinder is fixedly connected to the retaining ring guide block. A guide rail is provided between the bottom of the retaining ring guide block and the upper support plate of the mounting frame to ensure stable and reliable linear conveying of the retaining ring guide block.

[0015] The material mixing seat is also provided with a first pressure plate above the feeding positioning block. The first pressure plate is fixed to the mounting frame by a first connecting bracket. The first connecting bracket is also provided with a first sensor at the position of the composite gasket feeding station. The first pressure plate is provided with a first clearance hole at the composite gasket feeding station. The first sensor detects whether the composite gasket is fed into place through the first clearance hole.

[0016] The material mixing seat is provided with a second pressure plate corresponding to the straight travel direction of the retaining ring guide block. The second pressure plate is fixed to the mounting frame by a second connecting bracket. The second connecting bracket is provided with a second sensor corresponding to the retaining ring positioning notch position when the retaining ring is in the material feeding state. The second pressure plate is provided with a gap around the retaining ring positioning notch when the retaining ring is in the material feeding state. The second sensor detects whether the retaining ring is in place through the gap.

[0017] The second pressure plate is provided with a third guide notch corresponding to the position of the composite feeding station, and the feeding positioning block is provided with a lifting clearance opening corresponding to the position of the composite feeding station. When the lifting rod of the lifting and pressing cylinder is in working state, it passes through the lifting clearance opening to push the composite gasket into the lower installation space of the retaining ring. The external transfer mechanism takes away the composite gasket and retaining ring combination structure through the third guide notch.

[0018] With this invention, the composite washers in the second hopper are conveyed one by one to the starting end of the contouring channel via a vibrating hopper along the second material channel. Then, the composite washer pusher cylinder drives the composite washer located at the composite washer loading station to move to the lower layer of the composite loading station. The composite washers in the first hopper are conveyed one by one to the retaining ring guide block with a retaining ring positioning notch via a vibrating hopper along the first material channel. Then, the retaining ring guide block pusher cylinder drives the retaining ring in the retaining ring positioning notch to move linearly to the upper layer of the composite loading station. Then, the lifting and pressing cylinder lifts and pushes the composite washer into the lower installation space of the retaining ring. After that, the external transfer mechanism removes the composite washer and retaining ring assembly structure. Then, the composite washer pusher cylinder and the retaining ring guide block pusher cylinder reset, and the cycle repeats. This allows the composite washer to be directly assembled with the retaining ring before loading, reducing the number of workstations in the bearing assembly equipment and thus improving the bearing assembly efficiency.

Then, the retaining ring guide block pusher cylinder drives the retaining ring in the retaining ring positioning notch to move linearly to the upper layer of the composite loading station. Then, the lifting and pressing cylinder lifts and pushes the composite washer into the lower installation space of the retaining ring. Then, the external transfer mechanism removes the composite washer and retaining ring combination structure. After that, the composite washer pusher cylinder and the retaining ring guide block pusher cylinder reset, and the operation is repeated. This allows the composite washer to be directly assembled with the retaining ring before loading, reducing the number of workstations in the bearing assembly equipment and thus improving the bearing assembly efficiency.
