Description

Technical Field

[0001] This utility model belongs to the field of CNC turning technology, and in particular relates to a workpiece feeding structure for CNC turning. Background Technology

[0002] CNC turning is a technology that uses CNC machine tools (CNC lathes) to perform rotary cutting operations on workpieces. By programming and controlling the cutting tools to follow a set trajectory, it performs various turning operations on the workpiece, such as external turning, internal turning, face turning, and thread turning. This technology has advantages such as high machining accuracy, high degree of automation, and suitability for mass production, and is widely used in fields such as machinery manufacturing, aerospace, and automotive. By changing the cutting tools and adjusting the program, it can also flexibly machine parts with different structures and materials.

[0003] Existing technologies disclose several utility model patents in the field of CNC turning technology. Among them, utility model patent application number CN221363921U discloses a workpiece loading rack structure for CNC machine tools. Its basic description is as follows: A workpiece loading rack structure for CNC machine tools, characterized by a base frame, support rod, storage box, top part, telescopic cylinder, and unloading part. One end of the base frame is fixedly connected to the support rod, and the top of the support rod is inclinedly fitted with the storage box. One end of the storage box is in contact with the top part, and the top part is connected to the telescopic cylinder. The telescopic end of the cylinder is connected, and the telescopic cylinder is fixedly installed on the base frame. The other end of the base frame is provided with a material dropping part. The material storage box installed at a certain inclined angle contains stored materials. The first shaft workpiece is located on the moving block. The telescopic cylinder controls the moving block to move upward. The moving block pushes the material out and slowly moves upward. When the top surface of the moving block and the top surface of the material dropping inclined plate are on the same inclined line, the workpiece rolls down the material dropping inclined plate into the positioning box due to the inclination of the bottom surface. Then the telescopic cylinder drives the moving block to reset, thus completing one workpiece loading operation.

[0004] The existing technology has the following problems during use: workpieces are prone to accumulation during feeding, resulting in poor feeding or jamming; the pusher structure may push multiple workpieces at the same time during operation, affecting the accuracy of feeding; in addition, workpieces cannot directly enter the processing area after being discharged, resulting in poor process connection and low operating efficiency. Utility Model Content

[0005] This utility model provides a workpiece feeding structure for CNC turning, aiming to solve the following problems existing in the prior art: workpieces are prone to accumulation during feeding, resulting in poor feeding or jamming; the pusher structure may push multiple workpieces at the same time during operation, affecting the accuracy of feeding; in addition, after the workpiece is unloaded, it cannot directly enter the processing area, resulting in poor process connection and low operating efficiency.

[0006] This utility model is implemented as follows: a workpiece feeding structure for CNC turning includes: a support frame, a storage device fixedly connected to the support frame, a pushing component attached to one side of the storage device, a guide plate attached to one side of the pushing component, both the pushing component and the guide plate being mounted on the support frame, a pushing device fixedly connected to one side of the guide plate, and a blocking device fixedly connected to the pushing component.

The two mounting plates are fixedly connected to the support frame, and the same drive motor is fixedly connected inside the two mounting plates. A turntable is fixedly connected to the output end of the drive motor, and an eccentric rod is fixedly connected to the eccentric part of the turntable. The extrusion rod is fixedly connected to the lower surface of the storage box.

[0009] Preferably, one end of the pull-back spring is fixedly connected to the bottom of the connecting leg, and the other end of the pull-back spring is fixedly connected to the fixing rod.

[0017] Compared with related technologies, the workpiece feeding structure for CNC turning provided by this utility model has the following beneficial effects:

[0018] 1. By setting up a storage device and a blocking device, when it is necessary to load a workpiece, the drive motor is started. The drive motor drives the turntable to rotate, and the turntable drives the eccentric rod to rotate synchronously. After the eccentric rod rotates to a certain area, it squeezes the extrusion rod. After the extrusion rod is squeezed, it drives the storage box to move. When the storage box moves, it drives the telescopic rod and the return spring to extend. After the extrusion rod moves away from the extrusion, the return spring applies elastic force to the connecting leg, so that the storage box and the telescopic rod are reset. During the reset, it shakes. At this time, the workpiece in the storage box can smoothly enter the pushing component after being shaken. At this time, after multiple workpieces are blocked by the baffle, a single tool enters the pushing component, which can complete the loading of the workpiece and avoid the workpiece getting stuck in the storage box.

[0019] 2. By setting up a pushing device, when the workpiece enters the two clamps, the infrared sensor detects the workpiece and activates the electric push rod through the command. The electric push rod pushes the workpiece into the processing area, thus completing the monitoring of the workpiece and avoiding the need for manual intervention. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a workpiece feeding structure for CNC turning, such as... Figure 1-4 As shown, it includes: a support frame 1, a storage device 2 fixedly connected to the support frame 1, a pushing component 3 attached to one side of the storage device 2, a guide plate 4 attached to one side of the pushing component 3, both the pushing component 3 and the guide plate 4 are mounted on the support frame 1, a pushing device 6 fixedly connected to one side of the guide plate 4, and a blocking device 5 fixedly connected to the pushing component 3.

[0028] The storage device 2 includes a storage box 201. Two connecting legs 202 are installed on the lower surface of the storage box 201. A telescopic rod 203 is fixedly connected to the lower part of the connecting legs 202. A fixed rod 204 is fixedly connected to the lower part of the telescopic rod 203. A pull spring 205 is sleeved on the telescopic rod 203.

[0029] In a further preferred embodiment of this utility model, the storage device 2 further includes two mounting plates 206 and an extrusion rod 210. The two mounting plates 206 are fixedly connected to the support frame 1. The same drive motor 207 is fixedly connected inside the two mounting plates 206. The output end of the drive motor 207 is fixedly connected to a turntable 208. An eccentric rod 209 is fixedly connected to the eccentric part of the turntable 208. The extrusion rod 210 is fixedly connected to the lower surface of the storage box 201. One end of the pull-back spring 205 is fixedly connected to the lower part of the connecting leg 202. The other end of the pull-back spring 205 is fixedly connected to the fixing rod 204. The storage box 201 is set in an inclined shape with a certain angle. One end of the eccentric rod 209 and the extrusion rod 210 are both provided with hemispherical parts that facilitate extrusion. The blocking device 5 includes a baffle 51. Two vertical rods 52 are symmetrically installed on the lower surface of the baffle 51. The two vertical rods 52 are fixedly connected to the pushing component 3. The height of the vertical rods 52 is slightly larger than the diameter of the workpiece cross-section.

[0030] In this embodiment, a pressing rod 210 is provided at the bottom of the storage box 201. One end of the return spring 205 is connected to the lower end of the connecting leg 202, and the other end is connected to the fixed rod 204. Through the elastic return action of the spring, the pressing rod 210 can quickly return to its original position after the eccentric wheel drives it to complete the pressing, ensuring the reciprocating stability of the pressing action. This structure can effectively prevent the workpiece from blocking at the outlet of the storage box 201. Through periodic pressing, the workpiece falls into the area of ​​the pushing component 3 one by one, improving the continuity and reliability of feeding. Two mounting plates 206 are firmly fixed on the support frame 1 for mounting the same drive motor 207. The drive motor 207 drives the eccentric wheel to rotate. A hemispherical contact surface is provided between the eccentric rod 209 and the pressing rod 210 to ensure smooth force transmission and buffering effect. This combination structure can realize periodic pushing of the bottom of the storage box 201. Through nonlinear curve motion, a gentle intermittent pressing is achieved, improving the controllability of the feeding rhythm and effectively reducing equipment operating noise and impact.

[0031] In a further preferred embodiment of this utility model, the pushing device 6 includes two fixed blocks 61 and an electric push rod 65. The two fixed blocks 61 are fixedly connected to the outside of the support frame 1. The same long plate 62 is fixedly connected to the two fixed blocks 61. Two clamping plates 63 are fixedly connected to the long plate 62. An infrared sensor 64 is provided in the two clamping plates 63. The infrared sensor 64 is fixedly connected to the long plate 62. The electric push rod 65 is fixedly connected to the long plate 62. V-shaped grooves are opened on the upper surface of the two clamping plates 63. The infrared sensor 64 and the electric push rod 65 are electrically connected.

[0032] In this embodiment, the long plate 62 serves as an installation platform, on which an infrared sensor 64 and an electric push rod 65 are mounted to form a closed-loop control system. The infrared sensor 64 can detect in real time whether the workpiece has entered the designated position. When the workpiece is detected to be in place, the electric push rod 65 is triggered to further push the workpiece. This combination of structures not only improves the intelligence of feeding, but also effectively prevents erroneous actions such as empty pushing or multiple pushing, thereby improving the accuracy and automation level of equipment operation.

[0033] In summary, when workpiece loading is required, the drive motor 207 is started, which drives the turntable 208 to rotate. The turntable 208 drives the eccentric rod 209 to rotate synchronously. After rotating to a certain area, the eccentric rod 209 presses the extrusion rod 210. After being pressed, the extrusion rod 210 moves the storage box 201. When the storage box 201 moves, it causes the telescopic rod 203 and the return spring 205 to extend. After the extrusion rod 210 moves away from the extrusion point, the return spring 205 then extends the connecting leg 20. 2. Apply elastic force to reset the storage bin 201 and telescopic rod 203. Shake during reset. The workpiece in the storage bin 201 can smoothly enter the pushing assembly 3 after being shaken. After multiple workpieces are blocked by the baffle 51, a single tool enters the pushing assembly 3 to complete the loading of the workpiece. When the workpiece enters the two clamping plates 63, the infrared sensor 64 detects the workpiece and starts the electric push rod 65 through the command. The electric push rod 65 pushes the workpiece, so that the workpiece enters the processing area.
