Description

Technical Field

[0001] This utility model relates to the field of lathe technology, specifically to a milling and turning platform and a CNC lathe. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] When machining workpieces, existing CNC lathes typically use a three-jaw chuck to clamp and fix one end of the workpiece, while the other end is fixed by a centering pin. Driven by the rotation of the three-jaw chuck, the tool post on the lathe slides to perform turning operations on the workpiece. However, when machining round parts, the end fixed by the centering pin may shift due to vibrations generated by the contact between the workpiece and the milling cutter, affecting the turning accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a milling and turning platform and a CNC lathe to solve the problem mentioned in the background art. When machining workpieces, existing CNC lathes usually use a three-jaw chuck to clamp and fix one end of the workpiece, while the other end is fixed by a centering pin. Under the rotation of the three-jaw chuck, the tool post on the lathe slides to perform turning operations on the workpiece. However, when machining round parts, the end fixed by the centering pin will be displaced due to the vibration generated by the contact between the workpiece and the milling cutter, which affects the turning accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a milling and turning platform, comprising a carriage and a clamping part:

[0006] The clamping part is rotatably disposed on the side of the slide. The clamping part includes a rotating cylinder rotatably disposed on the side of the slide. One end of the rotating cylinder is provided with a bearing. A sliding clamping block is slidably disposed inside the rotating cylinder. A transmission rod is rotatably disposed at one end of the sliding clamping block. A transmission joint is slidably disposed inside the rotating cylinder along the axis of the rotating cylinder. The circumference of the transmission joint is rotatably connected to the transmission rod. The transmission joint slides and drives the transmission rod to rotate so as to drive the transmission joint to slide displacement.

[0007] By adopting the above technical solution, when processing a workpiece, one end of the workpiece can be brought into contact with the transmission joint and pushed, causing the transmission joint to slide inside the rotating drum and drive the transmission rod to rotate. The rotating transmission rod then drives the sliding clamp to slide, thereby clamping and fixing one end of the workpiece.

[0008] Preferably, the clamping part further includes four sliding grooves opened inside the rotating drum, and four sliding clamping blocks are embedded in the sliding grooves and slidably connected thereto. The four sliding clamping blocks have a central rotational symmetry structure around the axis of the rotating drum.

[0009] By adopting the above technical solution, the sliding clamp block can slide along the groove inside the rotating drum.

[0010] Preferably, the clamping part further includes a clamping head disposed at the front end of the sliding clamping block, and the inward side of the clamping head is provided with an arc surface.

[0011] By adopting the above technical solution, the sliding displacement of the sliding clamping block can cause the clamping head to come into contact with the workpiece, thereby clamping and fixing the workpiece.

[0012] Preferably, the clamping part further includes a rotating groove formed inside the sliding clamp block, one end of the transmission rod is embedded in the rotating groove and rotatably connected to the sliding clamp block, each sliding clamp block is rotatably connected to one end of two transmission rods, the transmission joint is provided with rotating grooves around its perimeter, and each side of the transmission joint is rotatably connected to two transmission rods.

[0013] By adopting the above technical solution, the transmission rod can be rotated by the sliding displacement of the transmission joint inside the rotating drum, so that the rotating transmission rod can in turn drive the sliding clamp block to slide.

[0014] Preferably, the clamping part further includes a spring disposed at one end of the transmission joint and a pressure plate disposed at the other end of the transmission joint, the spring being located between the transmission joint and the rotating drum.

[0015] By adopting the above technical solution, the transmission section can be pushed outward by the spring, thereby enabling the outward sliding transmission section to drive the four sliding clamps to remain open.

[0016] A CNC lathe includes a milling and turning platform as described in any one of the above claims, and the CNC lathe further includes a lathe body:

[0017] The lathe body is equipped with a slide rail on its top, and a tool post is slidably mounted on the top of the slide rail along its direction. A three-jaw chuck is rotatably mounted inside the lathe body, and a power unit is mounted on the three-jaw chuck. The bottom of the carriage is slidably connected to the slide rail, and a locking structure is mounted inside the carriage.

[0018] By adopting the above technical solution, one end of the workpiece can be clamped and fixed by a three-jaw chuck, while the other end is fixed by a clamping part. Driven by the rotation of the three-jaw chuck, the tool post on the slide rail slides to perform turning operations on the workpiece.

[0019] Preferably, the rotation axis of the three-jaw chuck coincides with the rotation axis of the drum.

[0020] By adopting the above technical solution, it can be ensured that the workpiece can rotate stably along the axis.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by providing a slide and a clamping part, when processing a workpiece, one end of the workpiece can be made to abut against the transmission joint and push the transmission joint, so that the transmission joint slides inside the rotating drum and drives the transmission rod to rotate. The rotating transmission rod drives the sliding clamp to slide, thereby clamping and fixing one end of the workpiece, which increases the stability of the equipment when clamping the workpiece.

A bearing 203 is disposed at one end of the rotating cylinder 201. A sliding clamping block 204 is rotatably disposed inside the rotating cylinder 201. A transmission rod 206 is rotatably disposed at one end of the sliding clamping block 204. A transmission joint 207 is rotatably disposed inside the rotating cylinder 201 along the axis of the rotating cylinder 201. The circumference of the transmission joint 207 is rotatably connected to the transmission rod 206. The transmission joint 207 slides and drives the transmission rod 206 to rotate, thereby causing the transmission joint 207 to slide and move. When processing the workpiece, by having one end of the workpiece abut against the transmission joint 207 and push the transmission joint 207, the transmission joint 207 slides and moves inside the rotating cylinder 201, thereby driving the transmission rod 206 to rotate. The rotating transmission rod 206 drives the sliding clamping block 204 to slide and move, thereby clamping and fixing one end of the workpiece.

[0032] Example 2: Please refer to Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a milling and turning platform, including a clamping part 2, a transmission joint 207, and a sliding clamping block 204.

[0033] Four sliding grooves 202 are provided inside the rotating drum 201. Four sliding clamping blocks 204 are embedded in and slidably connected to the sliding grooves 202. The four sliding clamping blocks 204 have a centrally rotationally symmetrical structure around the axis of the rotating drum 201, allowing them to slide along the grooves 202 within the rotating drum 201. A clamping head 205 is provided at the front end of each sliding clamping block 204. The inward-facing side of the clamping head 205 has an arc surface, allowing it to contact the workpiece through the sliding displacement of the sliding clamping block 204, thereby clamping and fixing the workpiece. A rotating groove is provided inside each sliding clamping block 204. One end of a transmission rod 206 is embedded in the rotating groove and rotatably connected to the sliding clamping block 204. Each sliding clamping block 204 is connected to two... One end of the transmission rod 206 is rotatably connected, and the transmission section 207 has rotating grooves on all four sides. Each side of the transmission section 207 is rotatably connected to two transmission rods 206. The transmission section 207 can slide inside the rotating drum 201, which can drive the transmission rods 206 to rotate. The rotating transmission rods 206 can then drive the sliding clamps 204 to slide. A spring 209 is provided at one end of the transmission section 207, and a pressure plate 208 is provided at the other end of the transmission section 207. The spring 209 is located between the transmission section 207 and the rotating drum 201. The spring 209 can push the transmission section 207 to slide outward inside the rotating drum 201, so that the outward sliding transmission section 207 can drive the four sliding clamps 204 to remain open.

[0034] Example 3: Please refer to Figure 1 , Figure 2 and Figure 4 This embodiment provides another technical solution: a CNC lathe, which also includes a lathe body 3.

[0035] The lathe body 3 has a slide rail 301 on its top. A tool post 302 is slidably mounted on the top of the slide rail 301 along its mounting direction. A three-jaw chuck 303 is rotatably mounted inside the lathe body 3. The three-jaw chuck 303 is equipped with a power unit. The bottom of the carriage 1 is slidably connected to the slide rail 301. The carriage 1 has a locking structure inside, which allows the three-jaw chuck 303 to clamp and fix one end of the workpiece, while the other end is fixed by the clamping part 2. Driven by the rotation of the three-jaw chuck 303, the tool post 302 on the slide rail 301 slides to perform turning operations on the workpiece. The rotation axis of the three-jaw chuck 303 coincides with the rotation axis of the drum 201, which can ensure that the workpiece can rotate stably along the axis.

[0036] Working principle: First, the device is powered on. Then, one end of the workpiece is clamped and fixed by the three-jaw chuck 303. Then, the sliding displacement carriage 1 is moved along the slide rail 301, so that the other end of the workpiece abuts against the pressure plate 208. This pushes the transmission joint 207 to slide inside the rotating drum 201. The sliding displacement of the transmission joint 207 inside the rotating drum 201 drives the transmission rod 206 to rotate. The rotating transmission rod 206 can then drive the sliding clamp 204 to slide. A clamping head 205 is provided at the front end of the sliding clamp 204. The inward side of the clamping head 205 is provided with an arc surface. Through the sliding displacement of the sliding clamp 204, the clamping head 205 abuts against the workpiece, thereby clamping and fixing the workpiece. Then, driven by the rotation of the three-jaw chuck 303, the tool holder 302 on the slide rail 301 slides to perform turning operations on the workpiece.
