Detailed Description

As shown in figures 1-5, the metal pulley bracket comprises a track 1, wherein the track 1 extends forwards and backwards, three frames 2 are arranged at the top of the track 1, the frames 2 are uniformly distributed along the extending direction of the track 1, pulleys 3 are rotationally connected to the four corners of the bottom of the frames 2, the pulleys 3 are in sliding fit with the track 1, a fixing frame 4 is arranged at the top of the frame 2, the left end and the right end of the fixing frame 4 are bent upwards by ninety degrees, a lifting screw 5 is rotationally connected to the middle part of the bottom of the fixing frame 4, the lifting screw 5 downwards penetrates through the top of the frame 2, the lifting screw 5 is in threaded fit with the frame 2, a crank I6 is fixedly connected to the bottom end of the lifting screw 5, clamping screws 7 are in threaded connection with the left side wall and the right side wall of the fixing frame 4, clamping screws 7 are rotationally connected with clamping plates 8, the bottoms of the clamping plates 8 are in clearance fit with the tops of the fixing frame 4, and crank II are fixedly connected to the opposite ends of the two clamping screws 7.

Firstly, the rail 1 is fixed at a required position, the rail is ensured to be stable, the front-back extending direction is correct, the three frames 2 are placed on the rail 1 through the pulleys 3 at the bottom of the frames, the smooth sliding fit of the pulleys 3 and the rail 1 is ensured, and the clamping stagnation phenomenon is avoided.

The lifting screw rod 5 is rotated by the crank 6, and the lifting screw rod 5 is in threaded fit with the frame 2, so that the lifting screw rod 5 can move up and down along the top of the frame 2 during rotation, and the lifting screw rod 5 moves up and down to drive the fixing frame 4 and all parts (including the clamping screw rod 7, the clamping plate 8 and the like) on the fixing frame 4 to synchronously lift, so that the height adjustment of long and straight bars to be processed on the fixing frame 4 is realized.

The long straight bar to be processed is placed on the fixing frame 4, the bar is ensured to be positioned between the two clamping plates 8, the two crank handles 9 are respectively rotated, the clamping screw rod 7 is driven to rotate on the side wall of the fixing frame 4, and the clamping screw rod 7 moves towards the center during rotation due to the fact that the clamping screw rod 7 is in threaded connection with the fixing frame 4.

The clamping screw rod 7 moves to push the clamping plates 8 to approach the center until the clamping plates 8 tightly clamp the bar stock, so that the workpiece is firmly fixed.

After the height is adjusted and the workpiece is clamped, the frame 2 can be pushed to move back and forth along the track 1 so as to adapt to different processing position requirements, the rolling design of the pulley 3 ensures that the moving process is stable and the resistance is small, and after the pulley is moved to a designated position, the working procedures such as processing and cutting can be performed. The utility model protects only the mechanical part, and the functions realized by the software control part related to the mechanical part are not within the protection scope of the utility model.
