[0003] The staff often finds that different types and different models of cutters are used in the process of processing round steel during using the current round steel processing numerical control lathe, and in order to ensure safety, the machine needs to be stopped first when replacing the cutter, and then the staff uses tools to manually remove the original cutter and replace the new cutter, so that the stop replacement reduces the work efficiency. UTILITY MODEL CONTENTS
[0004] The utility model aims at solving the shortcomings in the prior art and provides a round steel processing numerical control lathe.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a round steel processing numerical control lathe, comprising a lathe body, two upright columns are slidably connected to the lathe body, a cross beam is commonly slidably connected to the two upright columns, a moving block is slidably connected to the cross beam, a fixed block is fixedly connected to the lathe body, a first motor is fixedly connected to the fixed block, a three-jaw chuck is fixedly connected to the output shaft of the first motor, a replacement structure is arranged on the lathe body, the replacement structure mainly comprises a cutter box, the cutter box is fixedly connected to the lathe body, a plurality of placing grooves are formed in the cutter box, a push plate is arranged in the placing groove, a plurality of air cylinders are fixedly connected to the lathe body, the piston rod of the air cylinder is fixedly connected with the push plate, a rubber pad is fixedly connected to the push plate, two sliding grooves are formed in the cutter box, and a dustproof plate is commonly slidably connected to the two sliding grooves.
[0006] The aforementioned components achieve the following effect: The operator mounts the round steel bar onto the three-jaw chuck, and then mounts the cutting tool onto the clamping device on the moving block. The two columns, crossbeam, and moving block are all driven by motors and lead screws. The user uses CAM software to write a machining program, generating G-code. The CNC system receives and parses the G-code instructions, and the control system converts the instructions into drive signals for the servo motors, controlling the tool movement to achieve numerical control and process the round steel bar. The first motor is started, and its output shaft drives the round steel bar to rotate via the three-jaw chuck. Different cutting tools are inserted into each slot, leaving one slot empty. When a cutting tool needs to be changed, the moving block can be adjusted to the corresponding position via the CNC system. Above the placement slot, the tool mounted on the clamping component of the moving block is placed in the empty placement slot. Then, the moving block is moved above the tool to be retrieved. The corresponding cylinder is activated by the CNC system, causing the piston rod of the cylinder to drive the push plate to push out the corresponding tool, making it easy for the clamping component to pick up the tool. This achieves automatic tool changing without stopping the machine. The rubber pad prevents the push plate from wearing down the tool head. When not in use, the dust cover can be slid to cover several placement slots to prevent dust from falling in. This avoids the current situation where, for safety reasons, the machine must be stopped before changing tools, and the operator must manually remove the old tool and replace it with a new one, which reduces work efficiency due to machine downtime.

[0014] The above-mentioned components achieve the effect that the tool is placed in the fixed ring, and the three clamping blocks clamp the tool by sliding the three slide rods, and the rubber pad improves the clamping effect.
[0015] Preferably, the moving block is rotatably connected with a rotating ring, and the rotating ring is fixedly connected with three adjusting blocks.
[0016] The above-mentioned components achieve the effect that counterclockwise rotation of the rotating ring causes the three adjusting blocks to push the three slide rods to slide inward synchronously, so that the clamping operation is more convenient.
[0017] Preferably, the slide rod is sleeved with a second spring, one end of the second spring is fixedly connected to the fixed ring, and the other end of the second spring is fixedly connected to the slide rod.
[0018] The above-mentioned components achieve the effect that when the tool is clamped, the three second springs are in a contracted state, so when the rotating ring is rotated clockwise, the three slide rods will slide outward under the action of the elastic force of the second spring, releasing the clamping of the tool, so that the tool can stay in the placing groove under the action of gravity.
[0019] Preferably, the moving block is rotatably connected with a rotating block, the rotating block is fixedly connected with a third motor, the output shaft of the third motor is fixedly connected with a second screw rod, the rotating ring is fixedly connected with a rectangular block, and the rectangular block is threadedly connected with the second screw rod.
