Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an auxiliary loading and unloading device for machining centers. Background Technology

[0002] CNC machining refers to precision machining controlled by computer digital control. CNC machining lathes, CNC milling machines, CNC boring and milling machines, etc. CNC machining centers include mold CNC machining centers. Mold CNC machining centers contain positioning devices for positioning mold workpieces. The positioning devices position the mold workpieces so that the CNC machining center can perform stable machining on the mold workpieces.

[0003] Machining centers evolved from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, thus achieving multiple machining functions.

[0004] In the prior art, there is a Chinese patent with authorization announcement number CN222269495U entitled "A CNC Machining Center Loading and Unloading Device". The patent discloses a CNC machining center loading and unloading device, including a loading and unloading belt conveyor and an adjustment component located at the bottom of the loading and unloading belt conveyor. The adjustment component includes a frame fixed to the bottom of the loading and unloading belt conveyor, and a connecting block is fixedly provided at the center of the bottom of the frame. The bottom of the frame is provided with a base plate, and two fixed seats are fixed at the top of the base plate. The two adjustment components are respectively provided on the front and rear sides of the connecting block, and the connecting block is rotatably connected to the fixed seats. Two electric push rods for driving the frame to rotate are provided between the frame and the base plate. The conveyor belt of the loading and unloading belt conveyor is provided with multiple sets of blocking components, which are used to prevent workpieces from falling during loading and unloading.

[0005] For example, Chinese patent CN208629000U, entitled "An Automatic Loading and Unloading Device for a Machining Center," discloses such a device. The device includes a machining table with a sleeve fixedly connected to its upper surface. A connecting rod is inserted into the sleeve, and a machining seat is fixedly connected to the upper surface of the connecting rod. The lower surface of the machining seat is fixedly connected to one end of a first spring. This automatic loading and unloading device, by incorporating a loading frame, a first cylinder, a second cylinder, and a telescopic rod, allows the first cylinder to drive the telescopic rod to push the workpiece upwards, and the second cylinder to push it into the machining slot for processing. This makes loading the machining center more convenient. Furthermore, by incorporating a spring rod, a second spring, a moving rod, and a third spring, the spring rod moves downwards under force, pressing the moving rod backwards. The reaction forces of the second and third springs then drive the unloading plate to push the workpiece downwards, achieving high loading and unloading efficiency.

[0006] While the aforementioned patents can meet the loading and unloading needs of machining centers to some extent, these devices also bring some operational inconveniences while improving processing quality and safety. To ensure safety and cleanliness during processing, machining centers are typically designed with a closed structure, which effectively prevents the spread of contaminants such as iron filings and cutting fluid, and also reduces noise levels. However, because machining centers are encased in sheet metal and have only one or two loading / unloading ports with protective doors, loading and unloading can only be done through these pre-existing ports after each processing cycle. This restricts operators' direct access to workpieces, increases loading and unloading time and complexity, and ultimately affects work efficiency. Utility Model Content

[0029] 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.

[0030] Please see Figures 1-9 This utility model provides a technical solution: an auxiliary loading and unloading device for a machining center, including a machine body 29, a support frame 1 installed on the machine body 29, a first positioning frame 2 slidably connected to the support frame 1 via a third positioning frame 4, a second positioning frame 3 rotatably connected to the first positioning frame 2; a loading and unloading assembly slidably connected to the second positioning frame 3; the loading and unloading assembly includes a first connecting plate 14 slidably connected to the second positioning frame 3, and also includes a tray 7, with a telescopic rod 9 provided between the tray 7 and the first connecting plate 14.

[0031] Specifically, the auxiliary loading and unloading device of the machining center includes a main body 29, which includes components such as a worktable and a tool magazine, which will not be described in detail here. A support frame 1 is mounted on the main body 29, and a first positioning frame 2 is slidably connected to the support frame 1 via a third positioning frame 4. Specifically, to improve the stability of the first positioning frame 2 during installation, the third positioning frame 4 is integrated with the support frame 1. A second positioning frame 3 is rotatably connected to the first positioning frame 2, and a loading and unloading assembly is slidably connected to the second positioning frame 3. The loading and unloading assembly includes a first connecting plate 14 slidably connected to the second positioning frame 3, and a tray 7 for storing the workpieces 28 being processed. A telescopic rod 9 is provided between the tray 7 and the first connecting plate 14. Specifically, the telescopic rod 9 can be designed as a multi-stage telescopic rod to meet the loading and unloading needs of the workpieces 28. Specifically, by sliding the first positioning frame 2 on the third positioning frame 4, rotating the second positioning frame 3 relative to the first positioning frame 2, and sliding the loading and unloading components on the second positioning frame 3, the pallet 7 can accurately reach the loading and unloading port of the machining center, adapting to the loading and unloading needs of workpieces 28 in different positions, greatly improving the flexibility and convenience of loading and unloading, and reducing the complexity and time cost of manual operation.

[0032] In the embodiments provided by this utility model, a sliding component is provided between the first positioning frame 2 and the third positioning frame 4. By providing the sliding component, it can be ensured that the first positioning frame 2 slides more smoothly and steadily, reducing friction and jamming during the sliding process, thereby improving the operating efficiency and reliability of the entire device, extending the service life of the equipment, and also helping to improve the accuracy and stability of loading and unloading.

Specifically, the size of the limiting component is set according to the working requirements. By reasonably setting the position and size of the limiting component, it can be ensured that the first positioning frame 2 moves within a safe range, improving the safety and reliability of the device, and also facilitating the operator to control and operate the device.

[0036] In the embodiments provided by this utility model, the limiting member includes a limiting shaft 17 slidably connected to the first positioning frame 2, and a horizontal groove is provided on the third positioning frame 4. When the first positioning frame 2 slides within the third positioning frame 4, the limiting shaft 17 slides within the horizontal groove. By sliding the limiting shaft 17 within the horizontal groove, the sliding range of the first positioning frame 2 can be directly limited, ensuring that it moves within a predetermined track and improving the stability of the first positioning frame 2 during sliding.

[0037] In the embodiments provided by this utility model, a locking component is further provided between the first positioning frame 2 and the third positioning frame 4. The locking component includes a guide seat 16 mounted on the first positioning frame 2, a limiting shaft 17 slidably connected to the guide seat 16, a screw 26 threadedly connected to the guide seat 16, and a pressing groove provided on the limiting shaft 17.

A compression spring 20 is provided between the pressing block and the pressing groove. More specifically, the locking component enables the first positioning frame 2 to be reliably fixed after sliding to a predetermined position, preventing it from accidentally sliding due to external forces during processing, thereby ensuring the stability and safety of the loading and unloading device during operation. At the same time, through the cooperation of the screw 26, the pressing block, and the compression spring 20, the locking and releasing of the limiting shaft 17 can be achieved, that is, the friction between the limiting shaft 17 and the horizontal groove can be adjusted to adjust the locking force, further improving the reliability and flexibility of the device.

[0038] In the embodiment provided by this utility model, a second connecting plate 24 is installed on the pallet 7, and a telescopic rod 9 is installed between the first connecting plate 14 and the second connecting plate 24.

[0039] In the embodiments provided by this utility model, the first connecting plate 14 and the second positioning frame 3 are slidably connected by a positioning component. The positioning component ensures that the sliding connection between the first connecting plate 14 and the second positioning frame 3 is more stable and reliable, avoiding loosening or falling off during the sliding process. Specifically, the positioning component includes a positioning rod installed on the first connecting plate 14, wherein a positioning groove adapted to the positioning rod is provided on the second positioning frame 3, and the positioning rod is slidably connected to the positioning groove. More specifically, a strong damping is provided between the positioning rod and the positioning groove, which can automatically adjust the position of the first connecting plate 14 according to the working needs to meet the working requirements.

[0040] In the embodiments provided by this utility model, the second positioning frame 3 and the first positioning frame 2 are rotatably connected by a rotating mechanism. The setting of the rotating mechanism enables the second positioning frame 3 to rotate flexibly relative to the first positioning frame 2, further expanding the movement range and flexibility of the loading and unloading components, adapting to the structure of different machining centers and the loading and unloading requirements of workpieces 28, improving the versatility and applicability of the device, and also providing operators with greater operating space and convenience.

[0041] In the embodiments provided by this utility model, the rotating mechanism includes a first limiting plate 13 installed on the first positioning frame 2, and a second limiting plate installed on the second positioning frame 3. An extension column 12 is provided on the second limiting plate, and the extension column 12 is rotatably connected to the first limiting plate 13, which can further improve the stability of the rotation when the first positioning frame 2 and the second positioning frame 3 are installed.

[0042] In the embodiments provided by this utility model, an overlapping block 11 is installed on the first limiting plate, and the extension column 12 is rotatably connected to the overlapping block 11 to avoid separation between the first positioning frame 2 and the second positioning frame 3, thereby improving safety.
