Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a CNC lathe that facilitates pipe bending. Background Technology

[0002] CNC lathes are modern machining equipment that uses digital information to automatically control the movement of machine tools and their machining processes. They are widely used in the precision machining of various shaft and disc parts. CNC lathes are one of the main types of CNC machine tools and occupy a very important position among them.

[0003] When machining bent pipes on existing CNC lathes, the irregular shape of the bent pipe makes it impossible to support it stably between the three-jaw chuck and the tailstock center like a straight shaft. During the machining process, especially when turning the end face, drilling or tapping, the cutting force can easily cause the bent pipe to rotate or move, which not only affects the machining accuracy and surface quality, but also poses safety hazards such as tool damage or even workpiece flying out. Utility Model Content

[0004] In view of this, the present invention provides a CNC lathe for convenient pipe bending, and the main technical problem to be solved is: the inability to stably fix the bent pipe, resulting in poor processing accuracy and quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a CNC lathe for convenient pipe bending, comprising a CNC lathe, wherein a connecting plate is fixedly connected inside the CNC lathe, and a fixed seat is fixedly connected to the top and right side of the connecting plate, a sliding column is movably connected inside the fixed seat, a clamping plate is movably connected inside the sliding column, and a bent pipe is placed inside the clamping plate, the fixed seat includes a seat body fixedly connected to the right side and top of the connecting plate, an adjusting screw is movably connected inside the seat body, a guide column is fixedly connected to the inner side of the seat body, and movable holes are provided on both the front and rear sides of the seat body.

[0006] By adopting the above technical solution, during use, the adjusting screw is turned so that it can rotate inside the base. The adjusting screw hole is adapted to the thread on the outside of the adjusting screw. By rotating the adjusting screw and turning it forward or backward, the column can move back and forth on the outside of the guide column, thereby adjusting the position of the clamping plate. By adjusting, the clamping plate can be positioned on the outside of both ends of the bend. The outer side of the bidirectional screw has two opposite threads, and the inside of the slider has a screw hole adapted to the thread on the outer side of the bidirectional screw. By turning the bidirectional screw and turning it forward or backward, the front and rear sliders can move simultaneously towards the middle or the front and rear sides. By moving the front and rear sliders simultaneously towards the middle, the plate is driven so that the fixing block can continuously move closer to the bend. As they move closer, the rubber pad can be pressed against the outside of the bend, thereby fixing the bend. Fixing is relatively convenient and can fix bends of different diameters. The fixed bend is more stable, which helps to ensure the processing accuracy and surface quality of the bend, and also ensures higher processing safety.

[0007] As a further description of the above technical solution: the CNC lathe includes a lathe body, a PLC controller and a control panel are fixedly connected to the front side of the lathe body, a tool mechanism is provided inside the lathe body, a movable door is movably connected to the front side of the lathe body, a base is fixedly connected to the lower part of the lathe body, and a spindle is movably connected inside the lathe body.

[0008] By adopting the above technical solution, the spindle is fixedly connected to the disc body to drive the disc body to rotate, which facilitates changing the position of the bent tube.

[0009] As a further description of the above technical solution: the connecting plate includes a plate body fixedly connected inside the CNC lathe, and a connecting column is fixedly connected to the right side of the plate body.

[0010] By adopting the above technical solution, the connecting column is used to connect with the two base bodies.

[0011] As a further description of the above technical solution: the sliding column includes a column body movably connected to the outside of the guide column, an adjusting screw hole is provided in the middle of the inside of the column body, and through holes are provided on both the front and rear sides of the inside of the column body. A bidirectional screw is movably connected inside the column body.

[0012] By adopting the above technical solution, the through hole is used for the column to move on the outside of the guide column, the outside of the bidirectional screw is provided with two opposite threads, and the inside of the slider is provided with a screw hole that matches the outside thread of the bidirectional screw. Tightening the bidirectional screw allows the two sliders to move simultaneously to the middle or to the front and back sides.

[0013] As a further description of the above technical solution: the clamping plate includes a slider movably connected inside the sliding column, a plate is fixedly connected to the side of the slider near the curved tube, a fixing block is fixedly connected to the inner side of the plate, and a rubber pad is fixedly connected to the outer side of the fixing block.

[0014] By adopting the above technical solution, the rubber pad is made of rubber material, which has a certain anti-slip effect, ensuring a more stable fixation of the bend and preventing scratches on the bend.

[0015] As a further description of the above technical solution: the midpoint between the clamping plates on the right side of the connecting plate's fixed seat coincides with the axis of the connecting plate.

[0016] By adopting the above technical solution, the axis of one end of the bent tube fixed between the two clamping plates on the right side coincides with the axis of the disc body, and the axis of the main spindle coincides with the axis of the disc body. This ensures that the main spindle can drive the disc body and one end of the bent tube fixed between the two clamping plates on the right side to rotate on the same axis, which facilitates the improvement of machining accuracy.

[0017] By employing the above technical solution, the CNC lathe of this utility model, which facilitates pipe bending, has at least the following beneficial effects:

[0018] Compared with existing technologies, this CNC lathe, which facilitates pipe bending, features clamping plates, sliding columns, and fixed seats. This design helps to stably fix the bent pipe. Tightening the adjusting screw changes the position of the column, which in turn changes the position of the two clamping plates on the column. This allows for easy adjustment of the clamping plate positions according to the size of the bent pipe. By adjusting the clamping plates, they can be positioned on the outer sides of both ends of the bent pipe. Then, turning the double-ended screw presses the rubber pads onto the outer sides of both ends of the bent pipe, thus fixing it in place. This method is convenient and can fix bent pipes of different diameters. The fixed bent pipe is more stable, ensuring the processing accuracy and surface quality, and also enhancing processing safety. Attached Figure Description

[0025] Reference Figure 1-4This utility model provides a CNC lathe for convenient pipe bending: It includes a CNC lathe 1, with a connecting plate 4 fixedly connected inside the CNC lathe 1. A fixed seat 3 is fixedly connected to the top and right side of the connecting plate 4. A sliding column 5 is movably connected inside the fixed seat 3, and a clamping plate 6 is movably connected inside the sliding column 5. A bent pipe 2 is placed inside the clamping plate 6. The fixed seat 3 includes a base 301 fixedly connected to the right side and top of the connecting plate 4. An adjusting screw 302 is movably connected inside the base 301. The inner side of the base 301... A guide post 303 is fixedly connected, which guides the movement of the column 501. The base 301 has moving holes 304 on both its front and rear sides. These holes allow the bidirectional screw 504 to pass through, ensuring its normal movement under the influence of the column 501. In use, the adjusting screw 302 is turned to allow it to rotate inside the base 301. The adjusting screw hole 502 is matched with the thread on the outer side of the adjusting screw 302. The rotation of the screw 302, by adjusting its forward or reverse rotation, allows the column 501 to move back and forth on the outside of the guide column 303, thereby adjusting the position of the clamping plate 6. The clamping plate 6 can be positioned on the outside of both ends of the bend 2. The double-acting screw 504 has two opposite threads on its outer side, and the slider 601 has a threaded hole inside that matches the outer thread of the double-acting screw 504. By turning the double-acting screw 504, the front and rear sliders 601 can move simultaneously towards the center or to the front and rear sides. This simultaneous movement of the two sliders 601 towards the center drives the plate 602, causing the fixing block 603 to continuously move closer to the bend 2. This continuous movement allows the rubber pad 604 to press against the outside of the bend 2, thus fixing the bend 2. This method is convenient and can fix bends 2 of different diameters. The fixed bend 2 is more stable, ensuring the processing accuracy and surface quality of the bend 2, and also enhancing processing safety.

[0026] Furthermore, the CNC lathe 1 includes a lathe body 101. A PLC controller 102 and a control panel 103 are fixedly connected to the front of the lathe body 101. A tool mechanism 105 is provided inside the lathe body 101. A movable door 107 is movably connected to the front of the lathe body 101. The movable door 107 can move left and right on the front of the lathe body 101. A base 106 is fixedly connected to the lower part of the lathe body 101. A spindle 104 is movably connected inside the lathe body 101. The spindle 104 is fixedly connected to the disc body 401 and is used to drive the disc body 401 to rotate, so as to facilitate changing the position of the bent tube 2.

[0027] Furthermore, the connecting plate 4 includes a plate body 401 fixedly connected inside the CNC lathe 1, and a connecting post 402 fixedly connected to the right side of the plate body 401. The connecting post 402 is used to connect with the two bases 301.

[0028] Furthermore, the sliding column 5 includes a column 501 movably connected to the outside of the guide column 303. An adjusting screw hole 502 is provided in the middle of the inside of the column 501. Through holes 503 are provided on both the front and rear sides of the inside of the column 501. The through holes 503 are used for the column 501 to move outside the guide column 303. A bidirectional screw 504 is movably connected inside the column 501. Two opposite threads are provided on the outer side of the bidirectional screw 504. The slider 601 has a screw hole inside that matches the thread on the outer side of the bidirectional screw 504. Tightening the bidirectional screw 504 allows the two sliders 601 to move simultaneously to the middle or to the front and rear sides.

[0029] Furthermore, the clamping plate 6 includes a slider 601 movably connected inside the sliding column 5. The slider 601 can move inside the sliding column 5. A plate 602 is fixedly connected to the side of the slider 601 near the bend 2. A fixing block 603 is fixedly connected to the inner side of the plate 602. A rubber pad 604 is fixedly connected to the outer side of the fixing block 603. The rubber pad 604 is made of rubber and has a certain anti-slip effect, ensuring that the bend 2 is fixed more securely and will not scratch the bend 2.

[0030] Furthermore, the midpoint between the clamping plates 6 on the right side of the connecting plate 4 and the axis of the connecting plate 4 coincides, so that the axis of one end of the bent tube 2 fixed between the two clamping plates 6 on the right side coincides with the axis of the plate body 401, and the axis of the spindle 104 coincides with the axis of the plate body 401, so that the axis of one end of the bent tube 2 fixed between the two clamping plates 6 on the right side coincides with the axis of the spindle 104, ensuring that the spindle 104 can drive the plate body 401 and one end of the bent tube 2 fixed between the two clamping plates 6 on the right side to rotate on the same axis, which facilitates the improvement of machining accuracy.

[0031] Working principle: During use, the adjusting screw 302 is turned so that it can rotate inside the base 301. By turning the adjusting screw 302 forward or backward, the column 501 can move back and forth outside the guide column 303, thereby adjusting the position of the clamping plate 6. By adjusting, the clamping plate 6 can be positioned outside both ends of the bend 2. By turning the bidirectional screw 504 forward or backward, the two sliders 601 can move simultaneously towards the middle or towards the front and rear sides. By moving the two sliders 601 towards the middle, the plate 602 is driven so that the fixing block 603 can move closer and closer to the bend 2. By moving closer and closer, the rubber pad 604 can be pressed against the outside of the bend 2, thereby fixing the bend 2. The fixing is relatively convenient and can fix bends 2 of different diameters. The fixed bend 2 is more stable, which helps to ensure the processing accuracy and surface quality of the bend 2, and also ensures higher processing safety.
