Description

Technical Field

[0001] This utility model relates to the field of automation device technology, and in particular to a loading and unloading device for CNC machine tools. Background Technology

[0002] With the increasing application of injection molded products, steel sleeves, as key inserts, play an important role in connecting different components. Their tails need to be through, and some steel sleeves have strict dimensional accuracy requirements at their tails, requiring secondary processing to meet assembly needs. This makes steel sleeve processing an indispensable part of the manufacturing industry.

[0003] In the existing technology, the processing of this type of steel sleeve generally adopts the traditional manual loading and unloading mode. The operation process is as follows: the steel sleeve to be processed is manually placed on the clamping fixture of the CNC lathe. After the CNC lathe completes the turning of the tail of the steel sleeve, the processed steel sleeve is removed from the clamping fixture by the operator. Then the above steps are repeated for the processing of the next steel sleeve.

[0004] However, in the existing manual loading and unloading process, operators need to extend their arms into the CNC lathe to perform the placement and removal actions. Since the CNC lathe operates at high speed, this greatly increases the risk of mechanical injury, posing a serious threat to the operator's safety. Furthermore, manual operation has limited speed and is prone to fatigue after prolonged work, leading to unstable loading and unloading intervals, difficulty in controlling the processing rhythm, and overall low production efficiency, failing to meet the demands of large-scale mass production. Moreover, manual loading and unloading requires dedicated operators, increasing labor costs; simultaneously, the instability of manual operation can lead to misalignment of the steel sleeve placement, resulting in defective products and further increasing material waste and rework costs.

[0005] With the continuous improvement of automation in the manufacturing industry, the existing manual loading and unloading mode is no longer suitable for the requirements of modern production for high efficiency, safety and low cost. Utility Model Content

[0023] like Figure 1-5 As shown, the present invention proposes a loading and unloading device for CNC machine tools, comprising: The main structure 100 is located at the usage site and adjacent to the CNC machine tool 500. The feeding mechanism 200 is mounted on the main structure 100, and is used for sorting and conveying steel sleeves. During use, the steel sleeves are placed in the feeding mechanism 200, and after sorting, they are conveyed one by one. The transfer mechanism 300 is mounted on the main structure 100, and supports the feeding mechanism 200. The handling mechanism 400 is mounted on the transfer mechanism 300, and grabs the steel sleeves conveyed by the feeding mechanism 200, places them into the CNC machine tool 500, and removes the steel sleeves processed by the CNC machine tool 500. Specifically, the handling mechanism 400... After the steel sleeve is picked up from the feed mechanism 200, it is conveyed by the transfer mechanism 300 to the loading position (where the steel sleeve is placed on the CNC machine tool 500).

After the steel sleeve is removed from the CNC machine tool 500, the next steel sleeve is placed in the CNC machine tool 500 for processing. The removed steel sleeves are recycled (which can be done manually or by an external robotic arm). This cycle is repeated to achieve automatic placement and removal of steel sleeves.

[0024] In addition, this utility model also includes a controller 600, which is connected to the feeding mechanism 200, the transplanting mechanism 300 and the handling mechanism 400 via data cables and controls the operation of each component.

[0025] The technical solution of this utility model achieves automatic loading and unloading of steel sleeves through the coordination of the feeding mechanism 200, the transplanting mechanism 300 and the handling mechanism 400. It eliminates the need for operators to put their arms into the high-speed CNC lathe, avoids the risk of mechanical injury accidents, and completely solves the safety hazards of manual loading and unloading.

[0026] Compared to the limited speed of manual operation and the unstable loading and unloading intervals caused by fatigue during long-term operation, this device can maintain a stable automated operation rhythm, avoid processing interruptions, effectively shorten the steel sleeve processing cycle, meet the demand for high-efficiency processing in large-scale mass production, and significantly improve overall production efficiency.

[0027] In addition, the technical solution of this utility model has two advantages. First, automated loading and unloading eliminates the need for dedicated operators, reducing labor costs. Second, the high precision of mechanical gripping and placement avoids deviations in the placement of steel sleeves caused by manual operation, reducing the rate of defective products, material waste costs, and rework costs, thus meeting the requirements of modern production for low cost.

[0028] like Figure 1 As shown, the main structure 100 includes a base plate 101 set at the point of use; several fixing components 102 set on a frame; in the fixed state, the fixing components 102 are connected to the base plate 101; several lifting components 103 are set on the frame, and when the fixing components 102 are adjusted, the frame is lifted by the lifting components 103; several casters 104 are set at the bottom of the frame; during use, the frame is fixed to the base plate 101 by connecting the fixing components 102 to the base plate 101; when the frame needs to be moved after use, the frame is raised by the lifting components 103, and the angle of the fixing components 102 is adjusted.

[0029] like Figure 2As shown, the transplanting mechanism 300 includes a transplanting plate 301 mounted on the main body 100; a first driving device 302 mounted on the transplanting plate 301; a moving track 303 mounted on the transplanting plate 301, and a moving plate 304 mounted on the moving track 303, the moving plate 304 being connected to the output shaft of the first driving device 302; a slider 305 mounted on the moving track 303, and a material distribution mounting plate 306 mounted on the slider 305; a second driving device 307 mounted on a vertical plate 308; and the vertical plate 308 being fixed to the transplanting plate 301; the transplanting mechanism 300... 01 After being fixed to the frame, the upper components are installed and supported; in actual use, the first drive device 302 drives the moving plate 304 to move linearly on the moving track 303. Since the conveying mechanism 400 is set on the moving plate 304, the moving plate 304 will drive the conveying mechanism 400 to change position during the movement; while the conveying mechanism 400 moves, the second drive device 307 is activated to stop the moving plate 304 and put the conveying mechanism 400 in the loading position, so as to put the steel sleeve into the CNC machine tool 500 or take out the steel sleeve. In addition, the transplanting mechanism 300 also includes a first limiting body 309 disposed on the transplanting plate 301 and positioned on one side of the moving plate 304; a second limiting body 310 disposed on the transplanting plate 301 and positioned on the other side of the moving plate 304; the first limiting body 309 and the second limiting body 310 respectively limit the movement position of the moving plate 304; when the moving plate 304 contacts the first limiting body 309, the first driving device 302 stops operating, and when the moving plate 304 contacts the second limiting body 310, the first driving device 302 stops operating; when the moving plate 304 separates from the second limiting body 310, the controller 600 receives a signal and controls the second driving device 307 to operate, while simultaneously controlling the first driving device 302 to stop operating; specifically, a third limiting body 311 is provided at one end of the moving plate 304; the output end of the second driving device 307 extends... After exiting, it contacts the third limiting body 311 to achieve positioning of the moving plate 304; in this utility model, the second driving device 307 is set below the moving plate 304. When the moving plate 304 separates from the second limiting body 310, the output end of the second driving device 307 moves and contacts the third limiting body 311, the second driving device 307 stops moving, and the conveying mechanism 400 places or removes the steel sleeve into the CNC machine tool 500; wherein, the second driving device 307 is provided with a contact plate 371, the contact plate 371 is connected to the output shaft of the second driving device 307, the contact plate 371 is provided with a sliding groove, the sliding groove is placed on the protrusion on the second driving device 307, so that when the second driving device 307 moves, it drives the contact plate 371 to move, and through the contact plate 371, it contacts the third limiting body 311 to achieve the second driving device 307 to stop moving; In this invention, the first limiting body 309 includes a limiting plate 391 and a hydraulic buffer 392 (the hydraulic buffer 392 is connected to the controller 600 via a signal line). During the movement of the moving plate 304, after contacting the hydraulic buffer 392, the first driving device 302 stops operating. Furthermore, the structures of the second limiting body 310 and the third limiting body 311 are the same as the first limiting body 309. Additionally, the first driving device 302, the second driving device 307, the first limiting body 309, the second limiting body 310, and the third limiting body 311 are respectively connected to the controller 600. When the moving plate 304 contacts the first limiting body 309, the signal generated by the first limiting body 309 is transmitted to the controller 600, which then controls the first driving device 302 to stop operating. When the first driving device 302 pushes the moving plate 304 to move, when the moving plate 304... 4. After contacting the second limiting body 310, the signal generated by the second limiting body 310 is transmitted to the controller 600, which controls the first driving device 302 to stop moving. When the moving plate 304 separates from the second limiting body 310 under the drive of the first driving device 302, the signal generated by the second limiting body 310 is transmitted to the controller 600, which controls the first driving device 302 to stop moving and the second driving device 307 to move. The second driving device 307 drives the contact plate 371 to contact the third limiting body 311. The third limiting body 311 generates a signal and transmits the signal to the controller 600, which controls the first driving device 302 and the second driving device 307 to stop running and stops the moving plate 304 at the loading position. Then, the controller 600 controls the conveying mechanism 400 to move. When the controller 600 controls the conveying mechanism 400 to place or remove the steel sleeve, the controller 600 controls the second drive device 307 to reset the contact plate 371, and controls the first drive device 302 to move the moving plate 304 to the position of the first limit body 309, and the conveying mechanism 400 grabs the next steel sleeve. The cyclical movement realizes the placement and grabbing operation of the steel sleeve by the conveying mechanism 400. In this utility model, the first drive device 302 and the second drive device 307 are both motors.

[0030] like Figure 3As shown, the feeding mechanism 200 includes a vibratory feeder 201 mounted on the main body 100; a feeding rack 202 mounted on the material distribution mounting plate 306, and a linear vibrator 203 mounted on the feeding rack 202; a feeding channel 204 mounted on the linear vibrator 203, and a first sensor 205 and a second sensor 206 respectively mounted at both ends of the feeding channel 204; and a material distribution device 207 mounted on the feeding rack 202, which extracts the steel sleeves fed from the feeding channel 204 one by one. According to actual usage needs, the position of the slider 305 on the moving track 303 can be adjusted, thereby adjusting the position of the material distribution mounting plate 306 to achieve material distribution. The position of the material rack is adjusted to meet the needs of the conveying mechanism 400. During use, the steel sleeves are poured into the vibratory feeder 201, and under the action of the vibratory feeder 201, the steel sleeves enter the feed channel 204. Under the action of the linear vibrator 203, the steel sleeves in the feed channel 204 are conveyed one by one. The first sensor 205 and the second sensor 206 detect the condition of the steel sleeves at both ends of the feed channel 204 respectively, and feed the detection results back to the controller 600. The controller 600 controls the material distribution device 207 to extract the steel sleeves on the feed channel 204, and the conveying mechanism 400 grabs the steel sleeves on the material distribution device 207. Specifically, the material distribution device 207 includes a material distribution plate 271 mounted on the feed rack 202, and a third drive device 272 mounted on the material distribution plate 271; a material taking plate 273 mounted on the output end of the third drive device 272, and a fourth drive device 274 mounted on the material taking plate 273, with an insertion rod 275 mounted on the output end of the fourth drive device 274; when the steel sleeve in the feed channel 204 is conveyed to the location of the first sensor 205, the first sensor 205 sends the detected signal to the controller 600, which then controls the third drive device 272 to perform the operation. The mechanism operates by simultaneously moving the material-grabbing plate 273, adjusting the position of the fourth drive device 274, and then actuating the fourth drive device 274 to insert the insertion rod 275 into the steel sleeve inside the feed channel 204. The fourth drive device 274 and the third drive device 272 then reset sequentially, moving the insertion rod 275 away from the feed channel 204. This provides sufficient movement space for the handling mechanism 400 to grasp the steel sleeve and prevents the handling mechanism 400 from contacting the feeding mechanism 200 when grasping the steel sleeve. In this invention, both the third drive device 272 and the fourth drive device 274 are cylinders.

[0031] like Figure 4As shown, the conveying mechanism 400 includes a conveying seat 401 mounted on the transplanting mechanism 300; a first reversing device 402 mounted on the conveying seat 401 and connected to one end of a first connecting arm 403; a second reversing device 404 mounted on the other end of the first connecting arm 403; and a second connecting arm 405 mounted on the second reversing device 404; a third reversing device 406 mounted on the second connecting arm 405 and connected to a synchronization device 407 at the other end of the second connecting arm 405 via a rotating belt; and a conveying head 408 mounted on the synchronization device 407. During use, the first connecting arm 403 rotates on the conveying seat 401 under the drive of the first reversing device 402, and during this rotation, the second reversing device 404, the second connecting arm 405, and the conveying head 408 simultaneously change position; the second connecting arm 405 is driven by the second reversing device 404. Rotation of device 405 allows for further adjustment of the position of the conveying head 408. Simultaneously, the third reversing device 406 drives the synchronizing device 407 to rotate, which in turn drives the conveying head 408 to rotate, thus changing the angle of the conveying head 408. In this invention, the third reversing device 406 and the conveying head 408 are connected by a rotating belt (preferably a timing belt or a regular belt). It should be noted that the first reversing device 402, the second reversing device 404, and the third reversing device 406 are all geared motors. The synchronizing device 407 is a rotating shaft that rotates under the drive of the third reversing device 406, simultaneously rotating the conveying head 408. Furthermore, the first reversing device 402, the second reversing device 404, and the third reversing device 406 are all connected to the controller 600, which controls their operation. The conveying head 408 includes a conveying frame 481 mounted on a synchronization device 407; a fifth drive device 482 is mounted on the conveying frame 481; a rotating body 483 is mounted on the fifth drive device 482, and a first conveying claw 484 and a second conveying claw 485 are respectively mounted at both ends of the rotating body 483; in actual use, the conveying claws are used to pick up and place steel sleeves; after the first conveying claw 484 picks up the steel sleeve from the feeding mechanism 200, the synchronization device 407 drives the conveying frame 481 to rotate to the position for placing the steel sleeve on the CNC machine tool 500, and the first conveying claw 484 places the steel sleeve into the CNC machine tool 500; after being transferred by the transfer mechanism 300, the first conveying claw 484 picks up the next steel sleeve. By adjusting the first connecting arm 403, the second connecting arm 405, and the transport frame 481, the second transport claw 485 removes the steel sleeve that has been processed inside the CNC machine tool 500. Under the drive of the fifth drive device 482, the rotating body 483 rotates, and the first transport claw 484 and the second transport claw 485 are swapped, placing the next steel sleeve on the first transport claw 484 onto the CNC machine tool 500. Thus, the steel sleeve picking and placing operation is completed in one adjustment of the first connecting arm 403 and the second connecting arm 405, improving the overall operating efficiency. In addition, the first transport claw 484 is a pneumatic gripper mounted on a cylinder, and the movement of the pneumatic gripper is controlled by the cylinder to grasp the steel sleeve. In this utility model, the fifth drive device 482 is a rotary cylinder.
