Detailed ways

As shown in Figures 1 and 2, a track conveying structure includes a support plate 1 and two long linear guide rails 2 arranged side by side on the support plate 1, and is characterized in that each of the long linear guide rails 2 includes a machine Frame 3, the guide bar 4 that is positioned at the top of frame 3 and the protective frame 5 erected on one side of frame 3, described protective frame 5 is provided with several transmission units, each transmission unit 6 includes transmission shaft 7 and setting The first C-shaped clamp 8 on the transmission shaft 7, the second C-shaped clamp 9, the spring 10, the first bevel gear 11, the first friction plate 12 and the second friction plate 13, the first C-shaped The clip 8 is connected to the spring 10, the spring 10 is connected to one end of the first bevel gear 11 through a thrust ball bearing, the other end of the first bevel gear 11 is connected to the first friction plate 12, and the first friction plate 12 is connected to the first bevel gear 11. A friction plate 12 is connected to the second friction plate 13, the second friction plate 13 is connected to the second C-shaped clamp 9, and the second bevel gear 14 is arranged between the frame 3 and each transmission unit 6 , the second bevel gear 14 and the first bevel gear 11 are arranged in a vertical position, the second bevel gear 14 meshes with the first bevel gear 11, and the second bevel gear 14 is provided with a bracket, The workpiece to be transported is placed on the bracket.

Wherein, the several transmission units share one transmission shaft 7 . The transmission shaft 7 is connected with the motor.

Wherein, the second friction plate 13 is a non-metal wear-resistant friction plate.

Wherein, the first bevel gear 11 is a non-metallic bevel gear.

Wherein, the second bevel gear 14 is a metal bevel gear with rollers.

The pressure between the first bevel gear 11 and the first friction plate 12 is provided by the spring 10 connected to the first bevel gear 11. When the materials of the first bevel gear 11 and the first friction plate 12 are constant, the first bevel The friction force between the gear 11 and the first friction plate 12 is a fixed value, which is set as the critical friction force F; when the bracket moves, the friction force between the bracket and the second bevel gear 14 is F1; when the bracket stops moving , the friction force between the bracket and the second bevel gear 14 is F2. By changing the friction coefficient and pressure between the bracket and the second bevel gear 14, F2>F, F1<F.

The motor drives the transmission shaft 7 to drive the second C-shaped clamp 9 and the second friction plate 13 to rotate. The second friction plate 13 is transmitted to the first friction plate 12 by friction force, and the connection between the first friction plate 12 and the first bevel gear 11 The friction force between them is F. When the bracket on the second bevel gear 14 is in a free state, the friction force between the bracket and the second bevel gear 14 is F1, and F1<F, the first friction plate 12 drives the first bevel gear 11 to rotate, and the first friction plate 12 drives the first bevel gear 11 to rotate. A bevel gear 11 meshes with the second bevel gear 14 to drive the bracket on the second bevel gear 14 and the workpiece to be transported on the bracket to move forward.

When the movement of the bracket on the second bevel gear 14 is restricted, the frictional force between the bracket and the second bevel gear 14 is F2. The transmission shaft 7 drives the second C-shaped clamp 9 and the second friction plate 13 to rotate, and the second friction plate 13 transmits to the first friction plate 12 by friction force. Since F2>F, the first friction plate 12 and the first bevel gear 11 relatively slides, and the first bevel gear 11 and the second bevel gear 14 are in a stopped state. Other transmission units not connected to the bracket are in normal transmission state and meet production requirements.

To sum up, the track conveying structure of the present invention has a simple structure, conveniently achieves the effect of moving or stopping the workpiece to be conveyed, and meets the production needs of the factory. On the other hand, when the track conveying structure of the present utility model is required to be in a partially stopped state, there is no need to disconnect the power supply of the entire conveying line, reducing the damage to the conveying line caused by frequent switching or closing, and the service life of the track conveying structure of the present utility model is greatly improved. extend.
