[0001] This utility model relates to the field of CNC lathe technology, specifically a slant bed linear guide CNC lathe with shock absorption effect. Background Technology

[0002] Slant bed CNC lathes are high-precision, high-efficiency automated machine tools. Equipped with multi-station turrets or power turrets, these machines offer a wide range of machining capabilities, capable of processing complex workpieces such as straight cylinders, slanted cylinders, arcs, and various threads, grooves, and worm gears. They also feature linear interpolation, circular interpolation, and various compensation functions, demonstrating excellent economic benefits in the mass production of complex parts.

[0003] A search revealed Chinese Patent CN213671853U, which discloses a slant bed linear guide CNC lathe with a protective mechanism. The lathe includes a lathe bed, a lathe body, and a protective mechanism, which comprises a protective cover and a support plate.

[0022] 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.

[0023] like Figure 1 As shown, this utility model provides a technical solution for a slant bed linear guide CNC lathe with shock absorption effect, including a lathe body 1. The lathe body 1 is electrically connected to an external municipal power supply through a wire, thereby effectively supplying power to the electrical equipment in this application.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, a damping mechanism 2 is provided on the outside of the lathe body 1. The damping mechanism 2 includes a damping box 201, which is fixed by fasteners such as fixing bolts. A damping rod 202 is fixedly connected to the inner bottom wall of the damping box 201. The damping rod 202 can provide motion resistance and effectively reduce the shaking force generated by the operation of the lathe body 1.

[0025] The extension end of the damping rod 202 is fixedly connected to the connecting rod 203. The outer surface of the connecting rod 203 is fixedly connected to the hinge frame 204. The outer surface of the damping rod 202 is sleeved with a buffer spring 205. The two ends of the buffer spring 205 are fixedly connected to the damping rod 202 and the hinge frame 204 respectively. The inner wall of the hinge frame 204 is hinged to the swing rod 206 through a pin. The buffer spring 205 effectively supports the lathe body 1, reduces the pressure on the damping rod 202, and buffers the shaking force of the lathe body 1.

[0026] The end of the swing rod 206 away from the hinge frame 204 is hinged to the hinge slider 207 by a pin. The bottom surface of the hinge slider 207 is slidably connected to the shock absorber box 201. When the swing rod 206 swings, it can drive the hinge slider 207 to slide on the inner bottom wall of the shock absorber box 201 at the same time.

[0027] The inner wall of the hinged slider 207 is slidably connected to a limiting rod 208. The two ends of the limiting rod 208 are fixedly connected to the shock absorber box 201. The limiting rod 208 effectively limits the hinged slider 207, making the hinged slider 207 more stable during movement.

[0028] The outer surface of the limiting rod 208 is fitted with a second buffer spring 209 and a third buffer spring 210. The two ends of the second buffer spring 209 and the third buffer spring 210 are fixedly connected to the shock absorber box 201 and the hinge slider 207, respectively. By sliding the hinge slider 207 in the length direction of the limiting rod 208, the second buffer spring 209 and the third buffer spring 210 can be simultaneously driven to extend and contract. Through the interaction of their elasticity, the movement force of the hinge slider 207 can be effectively buffered, thereby further reducing the shaking force of the lathe body 1.

[0029] The inner wall of the shock absorber 201 is slidably connected to a limit slider 211. The outer surface of the limit slider 211 is fixedly connected to the lathe body 1. The inner wall of the shock absorber 201 is fitted with a support spring 212. The two ends of the support spring 212 are fixedly connected to the shock absorber 201 and the limit slider 211 respectively. The support spring 212 can buffer and support the lathe body 1, effectively distributing the downward pressure of the damping rod 202 and the buffer spring 205.

[0030] like Figure 4 As shown, a protective mechanism 3 is provided inside the lathe body 1. The protective mechanism 3 includes a transmission rod 301. The outer surface of the transmission rod 301 is rotatably connected to the lathe body 1. A protective door plate 302 is fixedly connected to the outer surface of the transmission rod 301. A transparent plate 303 is fixedly connected to the inner wall of the protective door plate 302. With the setting of the transparent plate 303, when the protective door plate 302 is driven to close the working area of ​​the lathe body 1, the operator can observe the status of the workpiece being processed in real time.

[0031] A drive motor 304 is fixedly connected to the inner wall of the lathe body 1. A transmission rod 305 is fixedly connected to the output end of the drive motor 304. A control button for the drive motor 304 is installed on the outer surface of the lathe body 1. The drive motor 304 can be started and stopped by the control button. When the drive motor 304 is started, the transmission rod 305 can be driven to rotate.

[0032] The end of the transmission rod 305 away from the drive motor 304 is fixedly connected to the driving worm 306. The end of the driving worm 306 away from the transmission rod 305 is rotatably connected to the lathe body 1. The outer surface of the driving worm 306 is meshed with the driven worm wheel 307. The outer surface of the driven worm wheel 307 is fixedly connected to the transmission rod 301. By driving the driving worm 306 to rotate, the driven worm wheel 307 can be driven to rotate simultaneously according to the meshing force, effectively changing the rotation direction of the driving worm 306.

[0033] The damping rod 202 and the drive motor 304 in this application are common components and electrical equipment in the prior art, and this application will not elaborate on their models and internal structures.

[0034] Working principle: When the lathe body 1 shakes during the machining of the workpiece, the lathe body 1 will press the hinge frame 204 on the surface of the connecting rod 203 to move. The movement of the hinge frame 204 presses the damping rod 202 to extend and retract, and simultaneously causes the buffer spring 205 to extend and retract. The damping rod 202 and the buffer spring 205 can provide resistance to the shaking of the lathe body 1, effectively buffering and reducing the force generated by the shaking. During the movement of the hinge frame 204, it will simultaneously drive the swing rod 206 to swing. The swing rod 206 drives the hinge slider 207 to slide on the surface of the limit rod 208. The sliding of the hinge slider 207 compresses and stretches the buffer springs 209 and 210. The elasticity of the buffer springs 209 and 210 interacts simultaneously to... The hinged slider 207 can buffer the movement force of the hinged slider 207, effectively reducing the shaking of the lathe body 1, making the lathe body 1 more stable during workpiece processing, and greatly improving the quality of workpiece production. During workpiece processing, the drive motor 304 drives the active worm gear 306 at one end of the transmission rod 305 to rotate. The rotation of the active worm gear 306 drives the driven worm wheel 307 to rotate through the meshing force. The rotation of the driven worm wheel 307 drives the protective door plate 302 on the surface of the transmission rod 301 to rotate around the transmission rod 301 as the axis, effectively enclosing the processing area of ​​the lathe body 1, avoiding the situation where waste chips generated during workpiece processing are splashed and injure the staff, further making the device more practical and safe.
