Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a clamping device for a band saw. Background Technology

[0002] In machining, band saws are often used for processing, and clamping devices are needed to fix the workpiece during processing.

[0003] A band saw is disclosed in Chinese patent publication number CN205254240U. It can effectively block flying chips, and the band saw has uniform cooling and a simple structure.

[0004] While the aforementioned patent can effectively block flying chips, during the processing, the iron chips generated by the sawing machine are easily left in the clamping device, making them inconvenient to clean. Subsequent workpieces are easily misplaced, affecting processing accuracy. Feeding the material inward is also quite laborious, affecting efficiency. Utility Model Content

[0010] A further feature of this invention is that a second lead screw slide is fixedly installed at the bottom of the inner wall of the feeding box, and a second slider is slidably connected inside the second lead screw slide.

[0011] By adopting the above technical solution, the second lead screw slide is used to drive the second slider to move.

[0012] A further feature of this invention is that a movable plate is fixedly connected to the top of the second slider, and a pusher plate is fixedly connected to the top of the movable plate.

[0013] By adopting the above technical solution, the second slider is used to drive the moving plate and the pusher plate to move, thereby pushing the material.

[0014] A further feature of this invention is that: a first support rod is fixedly connected to both sides of the front side of the pusher plate, and a second support rod is fixedly connected to both sides of the back side of the pusher plate.

[0015] By adopting the above technical solution, the first support rod and the second support rod are used to limit the pusher plate, making the pusher plate move more stably.

[0016] A further feature of this invention is that a slide rail is provided in the middle of the inner wall of the feeding box, and a limit plate is slidably connected to the inner wall of the slide rail.

[0018] A further feature of this invention is that a base is fixedly installed at the bottom of the feeding box, and a protective block is fixedly connected to the bottom of the base.

[0019] By adopting the above technical solution, the base and protective block are used to support the feeding box.

[0020] A further feature of this invention is that a feeding plate is fixedly installed on one side of the feeding box, and a baffle is fixedly connected to one side of the upper surface of the feeding plate.

[0021] By adopting the above technical solution, the feeding plate is used to place materials, eliminating the need to remove materials from the ground each time, and the baffle prevents materials from falling.

[0022] A further feature of this invention is that a rubber strip is fixedly connected to the other side of the upper surface of the feeding plate.

When processing the workpiece, the workpiece is placed between the first clamping plate and the second clamping plate, and the cylinder is activated to push the first clamping plate to move towards the second clamping plate, clamping the workpiece for processing. After processing is completed... After releasing the workpiece, the first lead screw slide is activated to drive the first slider to descend. This, in turn, drives the connecting block and clamping table to descend via the tilting rod, retracting the clamping table into the band saw. Then, the first motor is activated to drive the tilting rod to rotate. As the tilting rod rotates, it drives the clamping table to rotate via the connecting block, causing iron filings on the surface of the clamping table to fall off. The clamping table continues to descend, and the second motor is activated to drive the roller brush to rotate, sweeping away the iron filings on the surface of the clamping table to prevent them from affecting the machining accuracy. During machining, the material to be processed can be placed on the feeding plate, and the workpiece to be processed can be placed on the feeding box. The second lead screw slide is activated to drive the second slider to move. The second slider drives the moving plate and the pusher plate to move, pushing the material. The first and second support rods are used to limit the pusher plate, making the pusher plate move more stably and facilitating feeding. Attached Figure Description
