Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding mechanism technology, specifically a feeding mechanism for machining cylindrical parts on a CNC lathe. Background Technology
[0002] The feeding mechanism for cylindrical parts machining on a CNC lathe is an auxiliary device used on CNC lathes. Its main function is to automatically or manually feed cylindrical parts into the machining area of the lathe, ensuring that the parts can stably and accurately enter the clamping device (such as a chuck) of the lathe during the machining process.
[0003] The cylindrical part feeding mechanism for CNC lathe disclosed in CN213944908U, although it has two limiting grooves on the side of the part box near the top surface of the support rod, and four pneumatic cylinders in pairs, all in the extended state, with the output ends of the two sets of pneumatic cylinders fixedly connected to limiting blocks, during feeding, the two pneumatic cylinders near the outlet of the part box retract, and the remaining pneumatic cylinders remain stationary, thereby releasing the cylindrical part, realizing the feeding operation of the cylindrical part, and at the same time preventing the cylindrical part from falling automatically, thus making it easier for the user to control the lathe to process the part.
[0004] However, the feeding mechanism for machining cylindrical parts on this CNC lathe has the following disadvantages:
[0005] (1) The feeding mechanism for cylindrical parts of the CNC lathe has a weak function of limiting the parts when feeding them. If the parts are of different sizes, the column body may not fall along the feeding direction when feeding them, causing the parts to get stuck on the inner wall of the device, which affects the normal feeding.
[0006] (2) The feeding mechanism for cylindrical parts of the CNC lathe has a weak buffering function for the parts. After the part is placed into the part box from the slot, the surface of the part will wear against the bottom wall of the device, which will reduce the service life of the part and the feeding mechanism. Utility Model Content
[0007] The purpose of this utility model is to provide a feeding mechanism for machining cylindrical parts on a CNC lathe, so as to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for machining cylindrical parts on a CNC lathe, comprising: a base, a limiting component, and a buffer component. A storage frame is fixedly connected to the top of the base, and a bidirectional screw is rotatably connected inside the storage frame. A knob is fixedly connected to one end of the bidirectional screw, and an adjusting slider is threadedly connected to the outer surface of the bidirectional screw. A limiting plate is fixedly connected to the bottom of the adjusting slider, and a limiting slider is fixedly connected to one side of the bottom of the limiting plate. Frames are fixedly connected to both ends of the top of the base, and a pneumatic rod is fixedly connected to the inner top wall of the frame. A stop block is fixedly connected to the bottom of the pneumatic rod.
[0009] A feeding frame is fixedly connected to the top of the storage frame, a telescopic rod is fixedly connected to the inner bottom wall of the storage frame, a spring is sleeved on the outer surface of the telescopic rod, a buffer plate is fixedly connected to the top of the telescopic rod, a protective layer is fixedly connected to the top of the buffer plate, a connecting slider is fixedly connected to the side of the buffer plate, and a connecting groove is provided on the inner side wall of the storage frame.
[0010] Optionally, a limiting groove is provided on one side bottom of the storage frame, and the outer surface of the limiting slider is slidably connected to the inner wall of the limiting groove. When the limiting slider slides inside the limiting groove, the limiting groove limits the limiting slider, thereby limiting the movement position of the limiting plate.
[0011] Optionally, the bottom of the spring is fixedly connected to the top side of the base, and the top of the spring is fixedly connected to the bottom of the buffer plate. Through the connection between the spring, the base, and the buffer plate, the base supports and fixes one end of the spring. When the spring extends or retracts, it will drive the buffer plate to move together.
[0012] Optionally, the number of telescopic rods is two, and the number of springs is two. The arrangement of two telescopic rods and two springs can improve the cushioning performance.
[0013] Optionally, the protective layer is made of rubber, and the bottom of the base is fixedly connected to a stand. The stand can support and fix the base while raising the height of the device.
[0014] Optionally, a rectangular slot is provided on one side of the top of the storage frame, and the outer surface of the stop is movably connected to the inner wall of the rectangular slot. The rectangular slot can prevent the stop from shifting position.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The cylindrical part feeding mechanism of this CNC lathe, through the setting of the limit component, when in use, rotating the knob drives the bidirectional screw to rotate. The bidirectional screw rotates and drives the adjusting slider and the limit plate to move, and at the same time drives the limit slider to move. The limit slider limits the movement position of the limit plate, thereby limiting the part when it falls, which improves the stability of the part feeding position. It avoids the situation where if the parts are of different sizes, the cylindrical body may not fall along the feeding direction, causing the parts to get stuck on the inner wall of the device and affecting normal feeding.
[0017] 2. The feeding mechanism for machining cylindrical parts on this CNC lathe, through the setting of a buffer assembly, allows the part to fall onto the buffer plate when it is placed in the device. At this time, the buffer plate presses down, causing the telescopic rod and spring to retract. The spring then rebounds to buffer the part. The protective layer can reduce the wear between the part and the buffer plate. When the buffer plate moves, it causes the connecting slider to slide inside the connecting groove. At the same time, the connecting groove limits the movement of the connecting slider, thereby preventing the buffer plate from shifting its position. This achieves the effect of protecting the feeding mechanism and avoids the situation where the surface of the part will wear against the inner wall of the device after the part is placed from the slot into the part box, which would reduce the service life of the part and the feeding mechanism.

[0023] 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.
[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution: a feeding mechanism for machining cylindrical parts on a CNC lathe, comprising: a base 1, a limiting component 2, and a buffer component 3. A storage frame 201 is fixedly connected to the top of the base 1. A bidirectional screw 202 is rotatably connected inside the storage frame 201. A knob 203 is fixedly connected to one end of the bidirectional screw 202. An adjusting slider 204 is threadedly connected to the outer surface of the bidirectional screw 202. A limiting plate 205 is fixedly connected to the bottom of the adjusting slider 204. One end of the limiting plate 205... A limiting slider 206 is fixedly connected to the bottom side. A frame 207 is fixedly connected to both ends of the top of the base 1. A pneumatic rod 208 is fixedly connected to the inner top wall of the frame 207. A stop block 209 is fixedly connected to the bottom of the pneumatic rod 208. Rotating the knob 203 drives the bidirectional screw 202 to rotate. The bidirectional screw 202 rotates to drive the adjusting slider 204 and the limiting plate 205 to move, and at the same time drives the limiting slider 206 to move. The limiting slider 206 limits the movement position of the limiting plate 205, thereby limiting the falling of the part.
[0025] A feed frame 301 is fixedly connected to the top of the storage frame 201. A telescopic rod 302 is fixedly connected to the inner bottom wall of the storage frame 201. A spring 303 is sleeved on the outer surface of the telescopic rod 302. A buffer plate 304 is fixedly connected to the top of the telescopic rod 302. A protective layer 305 is fixedly connected to the top of the buffer plate 304. A connecting slider 306 is fixedly connected to the side of the buffer plate 304. A connecting groove 307 is provided on the inner side wall of the storage frame 201. When a part is placed in the device, the part falls onto the buffer plate 304. At this time, the buffer plate 304 presses down, causing the telescopic rod 302 and the spring 303 to retract. Then, the spring 303 rebounds to buffer the part. The protective layer 305 can reduce the wear between the part and the buffer plate 304. When the buffer plate 304 moves, it causes the connecting slider 306 to slide inside the connecting groove 307. At the same time, the connecting groove 307 limits the connecting slider 306, thereby preventing the buffer plate 304 from shifting its position.
[0026] A limiting groove 4 is provided on one side bottom of the storage box 201. The outer surface of the limiting slider 206 is slidably connected to the inner wall of the limiting groove 4. When the limiting slider 206 slides inside the limiting groove 4, the limiting groove 4 limits the limiting slider 206, thereby limiting the movement position of the limiting plate 205.
[0027] The bottom of the spring 303 is fixedly connected to the top side of the base 1, and the top of the spring 303 is fixedly connected to the bottom of the buffer plate 304. Through the connection between the spring 303, the base 1 and the buffer plate 304, the base 1 supports and fixes one end of the spring 303. When the spring 303 extends or retracts, it will drive the buffer plate 304 to move together.
[0028] There are two telescopic rods 302 and two springs 303. The buffering performance can be improved by setting two telescopic rods 302 and two springs 303.
[0029] The protective layer 305 is made of rubber, and the bottom of the base 1 is fixedly connected to the foot bracket 5. The foot bracket 5 can support and fix the base 1 while raising the height of the device.
[0030] A rectangular slot is provided on one side of the top of the storage frame 201. The outer surface of the stop 209 is movably connected to the inner wall of the rectangular slot. The rectangular slot prevents the stop 209 from shifting position.
[0031] In this invention, the working steps of the device are as follows:
[0032] First step: Rotating knob 203 drives bidirectional screw 202 to rotate. The bidirectional screw 202 rotates, causing adjusting slider 204 and limiting plate 205 to move, and simultaneously causing limiting slider 206 to move. Limiting slider 206 limits the movement of limiting plate 205, thus limiting the part when it falls. When the part is placed in the device, it falls onto buffer plate 304. At this time, buffer plate 304 presses down, causing telescopic rod 302 and spring 303 to retract. Then spring 303 rebounds to buffer the part. Protective layer 305 can reduce wear between the part and buffer plate 304. When buffer plate 304 moves, it causes connecting slider 306 to slide inside connecting groove 307. At the same time, connecting groove 307 limits connecting slider 306, thereby preventing buffer plate 304 from shifting its position.
[0033] The second step: When the limiting slider 206 slides inside the limiting groove 4, the limiting groove 4 limits the limiting slider 206, and thus limits the movement position of the limiting plate 205. Through the connection of the spring 303 with the base 1 and the buffer plate 304, the base 1 supports and fixes one end of the spring 303. When the spring 303 extends and retracts, it will drive the buffer plate 304 to move together. The setting of two telescopic rods 302 and two springs 303 can improve the buffer performance. The setting of the foot bracket 5 can support and fix the base 1 while raising the height of the device. The setting of the rectangular slot can prevent the stop block 209 from shifting position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
