Description

Technical Field

[0001] The present application relates to the field of mechanical manufacturing equipment, and in particular to a boring machine Background Art

[0002] A boring machine is a machine tool that mainly uses a boring cutter to bore prefabricated holes in a workpiece. When processing an arc-shaped metal block, the arc-shaped metal block is generally placed on a workbench, and then the boring cutter is driven to rotate by the main machine to cut the arc-shaped metal block. During this cutting process, a large amount of iron chips will be generated, and the iron chips will remain on the workpiece, which can easily affect the accuracy of the workpiece processing. Summary of the invention

[0003] In order to facilitate the processing of iron filings remaining on a workpiece, the present application provides a boring machine.

[0004] The present application provides a boring machine, which adopts the following technical solution:

[0005] A boring machine comprises a machine body and a workbench for mounting a workpiece, wherein a turntable is rotatably connected to the machine body, a tool holder is fixed to the turntable, a tool head is fixedly connected to the tool holder, electromagnetic plates are arranged on both sides of the tool head, and a power supply device for powering on or off the electromagnetic plates is arranged on the tool holder.

[0006] By adopting the above technical solution, the electromagnetic plates are arranged on both sides of the cutter head, so that when the cutter head is cutting the workpiece, the electromagnetic plates are powered by electricity and rotate to generate magnetic force to adsorb iron chips. When the electromagnetic plates rotate to the outside of the workpiece following the tool holder, the power supply to the electromagnetic plates is cut off by the power supply device, so that the electromagnetic plates lose magnetic force and the iron chips fall off, so that the iron chips remaining on the workpiece can be brought to the outside of the workpiece, preventing the iron chips from remaining on the workpiece and affecting the processing accuracy of the workpiece.

[0007] Optionally, a connecting rod is slidably connected to the tool holder along its length direction, the electromagnetic plate is fixed on the connecting rod, a driving member for driving the connecting rod to slide is provided on the machine body, the power supply device includes a power supply block and a battery, the battery and the power supply block are both fixed on the tool holder, the battery and the power supply block are electrically connected, a conductive block is provided on the connecting rod, and the connecting rod slides to allow the conductive block to contact or detach from the power supply block.

[0008] By adopting the above technical scheme, when the workpiece is cut with a head, the conductive block and the power supply block collide with each other, the electromagnetic plate is energized, and the iron chips are adsorbed. After the tool holder rotates to the point where the electromagnetic plate is located outside the workpiece, the conductive block is separated from the power supply block through the sliding connection of the driving member, the electromagnetic plate is powered off, and the iron chips adsorbed on the electromagnetic plate fall off. The power supply device has a simple structure and is easy to operate. For some arc-shaped workpieces, when the arc surface is long, it is difficult for the electromagnetic plate to separate from the workpiece range even if it rotates, but the sliding of the connecting rod can enable the electromagnetic plate to separate from the workpiece better.

[0009] Optionally, the driving member includes a fixing rod, which is fixed to the machine body, and the end of the connecting rod away from the cutter head rotates to abut against the fixing rod and slides under the resistance of the fixing rod so that the electromagnetic plate is located outside the workpiece and the conductive block is separated from the power supply block; a spring is provided on the tool holder for resetting the connecting rod.

[0010] By adopting the above technical solution, when the tool holder rotates to the point where the electromagnetic plate is located outside the workpiece, one end of the connecting rod abuts against the fixed rod and slides under the action of the fixed rod, so that the conductive block is separated from the power supply block. The driving component has a simple structure and utilizes the rotation of the tool holder to stabilize the transmission, while the spring facilitates the resetting of the connecting rod and the continuous operation of the electromagnetic plate.

[0011] Optionally, one end of the connecting rod away from the cutter head is fitted and fixedly connected with a rubber pad.

[0012] By adopting the above technical solution, the collision between the connecting rod and the fixing rod can be alleviated.

[0013] Optionally, a mounting block is fixedly connected to the connecting rod, and a clearance groove is provided on the mounting block for the conductive block to be inserted, and the clearance groove is provided with two springs for pressing the conductive block against the power supply block, and the end of the conductive block away from the cutter head is an arc-shaped convex surface.

[0014] By adopting the above technical solution, the second spring has a pre-tightening effect, which can make the conductive block stably contact the power supply block to a certain extent, and the arc surface setting of the conductive block facilitates the conductive block to contact the power supply block again.

[0015] Optionally, a hanging ring is provided on the conductive block, and a hook for hanging the hanging ring is fixedly connected to the connecting rod. When the hanging ring is hung on the hook, the conductive block is separated from the power supply block.

[0016] By adopting the above technical solution, when the electromagnetic plate does not need to be energized, the hanging ring can be hung on the hook to separate the conductive block and the power supply block.

[0017] Optionally, the electromagnetic plate is rotatably connected to the connecting rod, and the connecting rod is provided with a nut for locking the electromagnetic plate.

[0018] By adopting the above technical solution, the angle of the electromagnetic plate can be adjusted to adapt to different adsorption requirements.

[0019] Optionally, the workbench is provided with a collection box for receiving iron filings from the electromagnetic plate.

[0020] By adopting the technical solution, it is convenient to collect iron filings.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The present application facilitates the transportation of iron chips remaining on the workpiece to the outside of the workpiece by setting an electromagnetic plate and a power supply device, thereby preventing iron chips from remaining on the workpiece and affecting the machining accuracy of the workpiece;

[0023] 2. The present application can, through the provision of spring 2, to a certain extent, enable the conductive block to stably contact the power supply block. BRIEF DESCRIPTION OF THE DRAWINGS
