Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe with a workpiece guiding structure. Background Technology

[0002] A CNC lathe is a machine tool controlled by computer numerical control technology. It is mainly used to process workpieces with rotational symmetry. The CNC lathe controls the machine tool's movements through computer programming and mainly consists of cutting tools, chuck, bed, CNC system, etc. During the machining process, the operator writes G-code to instruct the CNC system to control the machine tool's movement path and machining process, thereby accurately machining the parts.

[0003] When fixing a shaft workpiece on a CNC lathe, a chuck is used to limit the workpiece. At this time, the operator needs to ensure that the workpiece is aligned with the center of the chuck. Generally, it is necessary to support or adjust the workpiece to help it stabilize in the chuck and ensure that the workpiece enters the chuck correctly. Therefore, the operator generally needs to spend more physical strength and energy to ensure the stability of the workpiece, which increases the labor intensity. Therefore, we propose a CNC lathe with a workpiece guiding structure. Utility Model Content

[0004] The purpose of this invention is to provide a CNC lathe with a workpiece guiding structure to solve the problem mentioned in the background art, where operators need to support or adjust the workpiece when fixing the shaft workpiece on a CNC lathe, requiring a lot of physical strength and effort to ensure the stability of the workpiece, thus increasing labor intensity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC lathe with a workpiece guiding structure, comprising a CNC lathe body and a chuck, wherein the chuck is installed on the inner side of the CNC lathe body, and a connecting pipe is fixed on the outer side of the CNC lathe body, and two sliding grooves are formed on the outer side of the connecting pipe, wherein the sliding grooves are slidably connected to the slide plate, and the inner side of the connecting pipe is movably connected to a gear through a bearing, wherein a threaded groove is formed on the inner side of the gear, and a screw passes through the inside of the threaded groove, wherein the upper end of the screw is fixed to the slide plate.

[0006] Preferably, gear one is mated to gear two on its outer side, and the lower side of gear two is movably connected to the main body of the CNC lathe via a bearing.

[0007] Preferably, the upper side of the second gear is movably connected to the first support plate via a bearing, and the first support plate is connected to the main body of the CNC lathe.

[0008] Preferably, a drive motor is installed on the upper side of the support plate one, and the output end of the drive motor is fixed to the gear two.

[0009] Preferably, a bracket is fixed to the lower side of the screw, and the outer side of the bracket is fixed to the connecting frame.

[0010] Preferably, a second screw runs through the interior of the connecting frame, and the inner side of the bracket is movably connected to the support cover via a rotating shaft.

[0011] Preferably, the lower end of the second screw is movably connected to the slide via a bearing, and the side of the support cover near the slide is connected to the second support plate.

[0012] Preferably, the second support plate has a second sliding groove on the side near the slide, and the slide is slidably connected to the second sliding groove.

[0013] Preferably, the first slide groove matches the slide plate, and the first gear and the second gear are meshed together.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The CNC lathe with a workpiece guiding structure rotates the second screw, causing the arc surface of the support to face upwards. The shaft workpiece is placed inside the support. The drive motor is started, allowing the support to move the shaft workpiece upwards towards the chuck. Once the shaft workpiece is aligned with the chuck, the shaft workpiece is pushed to engage with the chuck, thus binding the chuck and shaft workpiece together. At this point, the second screw is rotated in the opposite direction, causing the arc surface of the support to face downwards. The drive motor is then started, positioning the support above the shaft workpiece. This reduces the operator's workload when fixing the shaft workpiece on the CNC lathe. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-Figure 5 This utility model provides a technical solution: a CNC lathe with a workpiece guiding structure, including a CNC lathe body 1 and a chuck 101. The chuck 101 is installed on the inner side of the CNC lathe body 1, and a connecting pipe 2 is fixed on the outer side of the CNC lathe body 1. Two sliding grooves 201 are opened on the outer side of the connecting pipe 2, and the sliding grooves 201 are slidably connected to the slide plate 202. The inner side of the connecting pipe 2 is movably connected to a gear 203 through a bearing. A threaded groove 204 is opened on the inner side of the gear 203, and a screw 205 passes through the inside of the threaded groove 204. The upper end of the screw 205 is fixed to the slide plate 202. A gear 206 is connected to the outer side of the gear 203, and the lower side of the gear 206 is movably connected to the CNC lathe body 1 through a bearing. The upper side of the gear 206 is movably connected to a support plate 207 through a bearing. The support plate 207 is connected to the CNC lathe body 1. A drive motor 208 is mounted on the upper side of component 7, and the output end of the drive motor 208 is fixed to gear 206. A bracket 209 is fixed to the lower side of screw 205. The outer side of the bracket 209 is fixed to the connecting frame 210. Screw 211 passes through the interior of the connecting frame 210. The inner side of the bracket 209 is movably connected to the support cover 212 via a rotating shaft. The lower end of screw 211 is movably connected to the slide 213 via a bearing. The support cover 212 is close to the slide. One side of 213 is connected to the second support plate 214. The second support plate 214 has a second slide groove 215 on the side near the slide 213, and the slide 213 slides and connects with the second slide groove 215. The first slide groove 201 matches the slide plate 202. The first gear 203 meshes with the second gear 206. The threaded groove 204 is threadedly connected to the first screw 205. The connecting frame 210 is threadedly connected to the second screw 211. The slide 213 matches the second slide groove 215.

[0023] In specific implementation, according to Figure 1-Figure 5 When fixing the shaft workpiece on a CNC lathe, the second screw 211 is rotated and connected to the connecting bracket 210 by a thread, causing the second screw 211 to move downward along the connecting bracket 210. At this time, the second screw 211 pushes the slide 213 to slide along the inner side of the second slide groove 215, causing the slide 213 to press against the second slide groove 215. This causes the second support plate 214 to drive one side of the support cover 212 to rotate downward inside the bracket 209, so that the arc surface of the support cover 212 is horizontal and facing upward. At this time, the shaft workpiece can be placed on the support cover 212. Inside, the drive motor 208 is activated, causing its output to rotate gear 206. Gear 203 meshes with gear 206, causing gear 206 to rotate gear 203. The threaded groove 204 inside gear 203 rotates accordingly. The sliding groove 201 matches the sliding plate 202, preventing the threaded groove 204 from rotating the screw 205. The threaded groove 204 then connects to the screw 205, allowing the screw 205 to rotate. 05 moves upward along the threaded groove 204, causing the screw 205 to gradually retract into the connecting pipe 2. At this time, the screw 205 drives the support 212 to move upward, allowing the support 212 to stably drive the shaft workpiece upward, causing the shaft workpiece to gradually approach the chuck 101. When the shaft workpiece is aligned with the chuck 101, the operator can directly push the shaft workpiece to engage with the chuck 101, thus confining the chuck 101 and the shaft workpiece together. At this time, the screw 211 is rotated in the opposite direction, causing the screw 211 to drive the slide 213 upward, thereby... The slide 213 pulls the support plate 214 upward through the slide groove 215, causing the support cover 212 to rotate downward on the underside of the shaft workpiece, so that the arc surface of the support cover 212 faces downward. At this time, the drive motor 208 is started, causing the screw 205 to drive the support cover 212 upward, so that the support cover 212 is above the shaft workpiece. This ensures that the support cover 212 will not affect the cutting tool of the CNC lathe body 1 in processing the shaft workpiece. When the CNC lathe fixes the shaft workpiece, the operator does not need to support the workpiece, reducing the labor intensity of the operator.

[0024] In summary, when fixing the shaft workpiece on a CNC lathe, rotating screw 211 causes the arc surface of the support 212 to face upwards. The shaft workpiece can then be placed inside the support 212. The drive motor 208 is then activated, allowing the support 212 to stably move the shaft workpiece upwards towards the chuck 101. Once the shaft workpiece is aligned with the chuck 101, the operator can directly push the shaft workpiece to engage with the chuck 101, thus binding the chuck 101 and the shaft workpiece together. Then, screw 211 is rotated in the opposite direction, causing the arc surface of the support 212 to face downwards. The drive motor 208 is then activated, positioning the support 212 above the shaft workpiece. This eliminates the need for the operator to support the workpiece when fixing it on the CNC lathe, reducing the operator's workload. Content not described in detail in this specification is prior art known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
