Description

Technical Field

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

[0002] CNC lathes, as precision tools in modern manufacturing, are machine tools that achieve automated machining through computer numerical control technology. They can precisely control the movement trajectory of the cutting tool and machining parameters according to preset program instructions, thereby completing the turning of complex-shaped parts. Therefore, CNC lathes are often used for machining tubular materials.

[0003] The machining process of a CNC lathe involves controlling the relative position of the cutting tool and the raw material to bring them into contact and perform turning. Therefore, ensuring the accuracy of this relative position is crucial for controlling machining accuracy. To prevent uncontrollable deviation of the raw material during machining, a clamping device is needed to position it. While existing clamping devices can effectively clamp tubular materials, they are typically mounted at the end of the material and clamp from the outside. This results in some overlap between the clamping device and the end of the tubular material, causing interference between the cutting tool and the clamping device. Therefore, machining tubular materials on a lathe requires at least two passes, especially when machining the outer wall shape. That is, after machining a portion of the tubular material, it is rotated. Consequently, the machining efficiency of CNC lathes is relatively low when working with tubular materials.

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] A clamping device for CNC lathe machining includes: an adjusting screw 1, a sliding plate 2, a fixed plate 3, a power unit 4, a positioning structure 5, and an assembly housing 6. Multiple positioning structures 5 are arranged circumferentially along the sliding plate 2. The positioning structures 5 are positioned between the sliding plate 2 and the fixed plate 3. Each positioning structure 5 includes two positioning rods 51. The positioning rods 51 are oscillatingly connected. One positioning rod 51 is oscillatingly connected to the sliding plate 2, and the other positioning rod 51 is oscillatingly connected to the fixed plate 3. The sliding plate 2 and the fixed plate 3 are fitted onto the adjusting screw. The inner wall of the sliding plate 2 has threads corresponding to those on the adjusting screw 1. The power unit 4 is connected to the sliding plate 2 via the adjusting screw 1 to drive the sliding plate 2 closer to or further away from the fixed plate 3.

[0019] Specifically, the positioning structure 5 also includes a swing base 52 and a swing joint 53. The swing base 52 corresponds one-to-one with the positioning rod 51. The swing base 52 is swayably connected to the positioning rod 51. One swing base 52 is fixedly connected to the sliding plate 2. The other swing base 52 is fixedly connected to the fixed plate 3. The swing joint 53 is disposed between the positioning rods 51. The swing joint 53 includes a connecting plate 531 and a clamping plate 532. The clamping plate 532 is swayably connected to the connecting plate 531. The clamping plate 532 is fixedly connected to one of the positioning rods 51. The connecting plate 531 is fixedly connected to the other positioning rod 51.

[0020] In practical applications, the position of the tubular material is adjusted so that its center coincides with the adjusting screw 1. The tubular material is then pushed so that the adjusting screw 1 and the positioning rod 51 extend into the tubular material. At this time, the power device 4 is activated. Driven by the power device 4, the adjusting screw 1 rotates continuously, thereby causing the sliding plate 2 to move along the adjusting screw 1, gradually reducing the distance between the sliding plate 2 and the fixed plate 3.

[0021] When the distance between the sliding plate 2 and the fixed plate 3 decreases, the sliding plate 2 will press against the positioning rod 51, causing the positioning rod 51 to swing. At this time, the positioning rod 51 will swing relative to the sliding plate 2 and the fixed plate 3 with the swing base 52. At the same time, the swing joint 53 performs a corresponding action. That is, the connecting plate 531 swings relative to the clamping plate 532. Thus, based on the swinging process of the positioning rod 51, the swing joint 53 will gradually move away from the adjusting screw 1, and finally the swing joint 53 will come into contact with the inner wall of the tubular material. Thus, the tubular material is positioned by utilizing the friction between the swing joint 53 and the inner wall of the tubular material. Since the swing joint 53 and other structures are located inside the tubular material, the cutting tool will not interfere with the device, so when machining the outer wall shape of the tubular material, the lathe can complete the machining in one go, thereby improving the machining efficiency to a certain extent. On the other hand, the tubular material can be positioned within the range of motion of the swing joint 53. Therefore, this utility model can effectively adapt to tubular materials with different inner diameters.

[0022] Secondly, the positioning structure 5 also includes a bonding plate 54. The bonding plate 54 is provided with a connecting block 541, a rotating shaft 542, and positioning screws 543. The connecting block 541 clamps the swing joint 53. The rotating shaft 542 passes through the connecting block 541 and the swing joint 53. The positioning screws 543 are respectively located at both ends of the rotating shaft 542. The positioning screws 543 rotate with the rotating shaft 542. The screwing directions of the positioning screws 543 are opposite.

[0023] When the swing joint 53 approaches the inner wall of the tubular material, it will drive the bonding plate 54 to move synchronously. Thus, the bonding plate 54 will replace the swing joint 53 in contact with the inner wall of the tubular material. On one hand, a bonding plate 54 matching the inner diameter of the tubular material can be selected, allowing for a closer fit between the device and the tubular material, thereby enhancing the stability of the device's positioning. On the other hand, the contact area between the device and the tubular material can be increased, further improving the stability of the device's positioning. Simultaneously, when dealing with tubular materials of different inner diameters, the positioning screw 543 can be removed, allowing the rotating shaft 542 to be pulled out, and the bonding plate 54 can then be removed from the swing joint 53. Therefore, bonding plates 54 of different shapes and sizes can be selected to meet different usage requirements.

[0024] The power unit 4 includes a power motor 41, a driving gear 42, and a driven gear 43. The driven gear 43 is connected to the adjusting screw 1. The driving gear 42 is connected to the output end of the power motor 41. The driving gear 42 and the driven gear 43 mesh with each other.

[0025] When the power motor 41 is started, its output will drive the drive gear 42 to rotate. Driven by the drive gear 42, the driven gear 43 will rotate synchronously, thereby driving the adjusting screw 1 to rotate. When the adjusting screw 1 rotates, the aforementioned process can be performed.

[0026] The housing 6 has a through hole for the adjusting screw 1. The housing 6 also has a cavity for accommodating the power unit 4.

[0027] In practical applications, the mounting housing 6 can be combined with other assembly structures such as mounting flanges to facilitate the assembly of this device with other structures of the lathe. It is worth noting that the mounting housing 6 has corresponding through holes to connect wiring compatible with the power motor 41, thereby supporting the normal operation of the power motor 41.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
