Description

Technical Field

[0001] The present application relates to the technical field of CNC machine tools, and in particular to a CNC turning machine. Background Art

[0002] CNC turning machine is a CNC turning machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions and decode them, express them in coded numbers, and input them into the CNC device through information carriers to control the movement of the machine tool, thereby automatically processing parts according to the shape and size required by the drawing.

[0003] Turning generally processes round shaft-shaped parts, and general parts are manually clamped on the lathe for processing. However, when processing parts with longer diameters and lengths, manual clamping is more troublesome, resulting in a longer clamping time, and the clamping position is prone to offset, resulting in lower processing efficiency and quality of the turning machine. Summary of the invention

[0004] In order to improve the processing efficiency and processing quality of a special turning machine, the present application provides a special CNC turning machine.

[0005] This application provides a CNC turning machine, which adopts the following technical solution:

[0006] A CNC turning machine includes a box, a machine head arranged on the box, and a tool holder slidably arranged on the box and used for processing parts. The box is provided with a feeding mechanism for auxiliary feeding, and the feeding mechanism includes:

[0007] A sliding seat, wherein the sliding seat is slidably arranged on the box body, and the tool holder is located between the machine head and the sliding seat;

[0008] A first chuck and a second chuck, wherein the first chuck and the second chuck are rotatably disposed on the machine head and the sliding seat respectively so that two ends of the part abut against the first chuck and the second chuck and are used to clamp the part;

[0009] A first lifting platform and a second lifting platform, wherein the first lifting platform and the second lifting platform are respectively slidably arranged on the machine head and the tool holder, and the first lifting platform is located below the first chuck and cooperates with the second lifting platform to support and position the parts;

[0010] A driving assembly is arranged on the box body and connected with the sliding seat.

[0011] By adopting the above technical solution, the parts are hoisted and placed on the first lifting platform and the second lifting platform, and then the first lifting platform and the second lifting platform move up, and then the driving component starts to drive the sliding seat to move, and the movement of the sliding seat drives the second chuck to approach and abut against the part, so that the second chuck pushes the part to abut against the first chuck, and then the first chuck and the second chuck start to clamp the two ends of the part, and then the first lifting platform and the second lifting platform move down away from the part, and then the tool holder starts to process the part, thereby reducing the probability of reducing processing efficiency and quality due to manual clamping, thereby improving the processing efficiency and processing quality of the turning machine.

[0012] Optionally, the first chuck comprises:

[0013] A base plate, the base plate is rotatably arranged on the machine head, and three clamping claws are arranged on the base plate to slide radially along the base plate;

[0014] Three positioning plates are detachably arranged on three clamping jaws and are in contact with the parts for positioning and can be clamped on the side walls of the parts for positioning.

[0015] By adopting the above technical solution, the part contacts the base plate, and then the three clamps are started to drive the three positioning plates to clamp the part for positioning, thereby clamping the part. At the same time, the three positioning plates can be replaced as needed to adapt to the clamping of parts of different sizes, thereby increasing the adaptability of the parts.

[0016] Optionally, a mounting frame is mounted on the machine head so as to slide in a direction close to or away from the first chuck, the first lifting platform is arranged on the mounting frame and can be moved to the outside of the first chuck, and a movable cylinder connected to the mounting frame is arranged on the machine head.

[0017] By adopting the above technical solution, when the part needs to be supported and positioned, the mobile cylinder is started to drive the first lifting platform to move under the second chuck. When the part is clamped and the tool holder needs to process the part at the first lifting platform, the mobile cylinder drives the first lifting platform to move to the outside of the first chuck, thereby achieving auxiliary part clamping while reducing interference caused by part processing.

[0018] Optionally, the first lifting platform and the second lifting platform are both provided with a supporting mechanism, and the supporting mechanism includes:

[0019] Two supporting wheels, the two supporting wheels are rotatably arranged on the first lifting platform and are located on both sides of the part, and the part is placed on the two supporting wheels;

[0020] A support belt, which is sleeved on two support wheels and closely attached to the parts for support;

[0021] A tensioning assembly is slidably arranged on the first lifting platform and located inside the support belt. The tensioning assembly can move with the extrusion of the parts and tension the support belt to support the parts.

[0022] By adopting the above technical solution, the tensioning assembly makes the support belt in a tensioned state, and the parts are placed on the support belt, and the parts are pressed against the support wheel, the support wheel supports the parts, and the tensioned support belt is tightly attached to the parts for support, and the rotation of the parts drives the support belt to move, thereby improving the support effect on the parts, while also reducing the probability of relative rotation between the support belt and the parts and reducing the quality of the parts, and the tensioning assembly can move with the extrusion of the parts and always keep the support belt tensioned, so that the support belt can adapt to supporting parts of different sizes, thereby improving the adaptability of the support mechanism.

[0023] At the same time, when the parts are rough-machined, the machining allowance is large, so the parts are prone to vibrate and the machining quality is low. Therefore, the support mechanism supports the parts, reduces the probability of vibration of the parts, and improves the quality of the parts. When the parts are fine-machined, the machining allowance is small, so the probability of vibration of the parts is small. Therefore, the first lifting platform and the second lifting platform can also start to drive the support mechanism to separate from the parts, thereby reducing the probability of vibration of the parts. At the same time, it also reduces the probability of reduction in part quality due to relative displacement between the support belt and the parts, thereby improving the machining quality of the turning machine.

[0024] Optionally, the tensioning assembly comprises:

[0025] A first tensioning block and a second tensioning block, wherein the first tensioning block and the second tensioning block are slidably arranged on the first lifting platform along the radial direction of the part;

[0026] A tensioning spring, wherein both ends of the tensioning spring are respectively connected to the first tensioning block and the second tensioning block;

[0027] The first tensioning wheel and the second tensioning wheel are rotatably arranged on the first tensioning block and the second tensioning block respectively and pressed against the two opposite inner side walls of the support belt under the action of the tensioning spring and used for tensioning the support belt.

[0028] By adopting the above technical solution, the first tensioning wheel and the second tensioning wheel tension the support belt under the action of the tensioning spring, and at the same time the first tensioning wheel or the second tensioning wheel can also support the parts, thereby further improving the supporting effect on the parts while achieving the tensioning of the support belt.

[0029] Optionally, the tool holder is provided with a lifting component for driving the first lifting platform to move up and down, and the lifting component includes:

[0030] A pushing block, which is horizontally slidably disposed on the machine head and is provided with an inclined pushing surface for pushing the first lifting platform to move up and down;

[0031] A pushing cylinder, which is arranged on the machine head and connected to the pushing block;

[0032] A push rod, the push rod is arranged on the push block and is provided with an inclined guide surface close to one end of the support belt so as to facilitate pressing against the support belt, and two push rods are provided and are respectively located on one side of the two support wheels;

[0033] An arc-shaped push ring is arranged on the side wall on the opposite side of the two push rods and is located close to the support wheel. When the support belt is tightly attached to the part, the push rod and the arc-shaped push ring are located below the support belt. The upward movement of the first lifting platform can drive the push rod to press against the support belt, and the push rod continues to move to drive the arc-shaped push ring to press against the support belt for positioning.

[0034] By adopting the above technical solution, the push cylinder is started to drive the push block to move, and the movement of the push block drives the first lifting platform to move downward, and the downward movement of the first lifting platform drives the support belt in contact with the support wheel to separate from the part, and the push rod and the arc-shaped push ring are close to the support belt under the action of the push block, so that the push rod is pressed against the support belt for positioning, and the first lifting platform continues to move downward to drive the arc-shaped push ring to press against the support belt for positioning, so that the support belt moves down and away from the part, so that the support mechanism is completely disengaged from the part, thereby shortening the distance that the support mechanism moves to separate from the part, thereby achieving support for the part while also improving the processing efficiency of the turning machine.

[0035] At the same time, the arc-shaped push ring presses against the support belt to position the tensioning assembly, thereby reducing the probability of the tensioning assembly detaching from the first lifting platform, thereby improving the supporting effect of the supporting mechanism.

[0036] Optionally, the tool holder is provided with a tool for processing parts and a protective cover covering the tool, and the box body is provided with a cooling and dust collection mechanism connected to the protective cover, and the cooling and dust collection mechanism includes:

[0042] By adopting the above technical solution, the dust suction fan is started, and dust and hot air enter the dust suction box, and then the dust and hot air are cooled by the cooling component, so that the hot air is cooled and the dust falls down to the filter frame for collection, and the cooled air is blown to the tool through the cooling pipe, so as to collect the dust and cool the tool at the same time, and the cooling component cools the hot air, thereby reducing the probability of dust continuing to fly, so that more dust is moved to the filter frame for collection, thereby reducing dust pollution to the environment, and also improving the processing quality of the turning machine.
