Description

Technical Field

[0001] This utility model relates to the technical field of hardware accessories engraving and milling equipment, specifically an automatic engraving and milling equipment for the surface of hardware accessories. Background Technology

[0002] Generally, engraving and milling equipment is considered to be a CNC milling machine that uses small cutting tools, high-power and high-speed spindle motors. Engraving and milling equipment can both engrave and mill, and is a highly efficient and precise CNC machine tool. Its application range is relatively wide, widely used in industries such as one-time rough and finish machining of precision mold cores, mold copper electrodes, batch processing of aluminum products, and hardware accessories. For example, our company independently developed an automatic engraving and milling equipment for hardware accessories and its usage method, with Chinese patent announcement number CN114952354B. This equipment involves inserting two connecting plugs into and securing the hardware accessories, and then using an accessory clamping mechanism to secure the hardware accessories to a rotating plate. After the rotating plate rotates, the surfaces of each hardware accessory can respectively fit onto the front and rear rows of matching mold surface placement slots, providing a placement and support function. Furthermore, the rotary cylinders on both sides of the mold surface placement slots can rotate sequentially. The upper surface of the hardware parts is pressed and held in place, and then the base and multi-head milling mechanism press down to mill the surface of the hardware parts. This structure greatly improves the milling efficiency of hardware parts. However, in the existing technology, the connecting plug is mainly clamped by the pushing action of the telescopic cylinder, which makes the connecting plug stuck between the lower clamping slot and the upper clamping slot. Although this method is simple, the stability of fixing the two connecting plugs of the hardware parts needs to be improved. Moreover, since there is usually a groove protrusion between the lower clamping slot and the upper clamping slot, the picking and placing cannot be smooth and fast. In particular, after the processing is completed, they need to be removed one by one by hand, and the efficiency of loading and unloading needs to be improved. Therefore, it is necessary to propose an automatic engraving and milling equipment for the surface of hardware parts to improve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic engraving and milling equipment for the surface of hardware accessories, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a frame, hardware accessories, a milling head disposed on the upper side of the frame, and two connecting plugs integrally disposed at the bottom of the hardware accessories. A base plate is disposed in the middle of the frame, and a rotating table is rotatably connected to the upper side of the base plate. A plug-in frame plate for installing hardware accessories is fixedly disposed on the upper side of the rotating table. A plug-in slot is opened on the top surface of the plug-in frame plate for corresponding insertion of the connecting plugs. Multiple limiting rods for synchronously clamping the connecting plugs inside each plug-in slot are movably disposed on the inner side of the plug-in frame plate.

[0005] Preferably, each pair of limiting rods forms a group and is slidably inserted into the two sides of the insertion slot. The inner side of the insertion frame plate is provided with two sets of rectangular sliding plates for installing each limiting rod. The top and bottom surfaces of the rectangular sliding plates slide against the inner side of the insertion frame plate, and the insertion frame plate is provided with a synchronous drive structure for transmitting the relative displacement of the two sets of rectangular sliding plates.

[0006] Preferably, the synchronous drive structure includes a rotating rod rotatably connected to the inner side of the plug-in frame plate. The rotating rod is provided with two sets of transmission threads, with each pair of opposite transmission threads forming a set. The two sets of transmission threads are respectively connected to two sets of rectangular sliding plate threads. A drive motor for driving the rotating rod to rotate is installed on the left side of the plug-in frame plate.

[0007] Preferably, hydraulic telescopic rods are hinged to both the front and rear sides of the base plate. The telescopic ends of the hydraulic telescopic rods are movably connected to the rotating platform and are used to push the rotating platform to flip to the right. A horizontal upright plate is installed on the upper left side of the base plate. The horizontal upright plate is used to support the left side of the bottom surface of the rotating platform to keep it horizontal. A rubber pad is laminated on the upper side of the horizontal upright plate and makes elastic contact with the bottom surface of the rotating platform.

[0008] Preferably, L-shaped connecting rods can be detachably connected to both the front and rear sides of the rotating platform, and the middle part of the L-shaped connecting rod is set downward and rotatably connected to the telescopic end of the hydraulic telescopic rod.

[0009] Preferably, a conveyor belt is installed on one side of the frame, and the conveyor belt is located on the right side of the base plate. When the rotating table is pushed to flip to the right, the plug-in frame plate is positioned above the conveyor belt.

[0010] Preferably, the connecting plug has an inwardly recessed groove in the middle, and the end of the limiting rod is fitted and locked into the groove.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model features a plug-in frame plate on the rotating table. The plug-in frame plate has plug-in slots that allow the two connecting plugs at the bottom of the hardware parts to be inserted. This allows the hardware parts to be placed quickly and smoothly on the plug-in frame plate without the connecting plugs being stuck by the slot protrusions. Furthermore, during discharge, the hardware parts on the plug-in frame plate can be quickly unloaded by directly combining the rotation effect of the rotating table with the flipping effect of the rotating table onto the conveyor belt.

[0013] Meanwhile, a synchronous drive structure is provided on the inner side of the plug-in frame plate, which can synchronously push the two sets of limit rods to move relative to each other and press them against the annular groove in the middle of the two connecting plugs. This synchronous clamping has a good effect, the connecting plugs are not easy to fall off, and can work with the rotation of the rotating table to flip the clamped hardware over to the top of the conveyor belt. After the limit rods return to their original positions, the connecting plugs can slide down to the conveyor belt for outward conveying. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to this document. Figures 1-2 This utility model provides a technical solution for an automatic engraving and milling equipment for hardware accessories: it includes a frame 1, hardware accessories 3, an engraving and milling head 2 located on the upper side of the frame 1, and two connecting plugs 31 integrally set at the bottom of the hardware accessories 3. The frame 1 is mounted on a base plate 4 through a cross slide in the middle, which enables the base plate 4 to move flexibly and move the position of the hardware accessories 3 to be milled by the engraving and milling head 2. A rotating table 5 is rotatably connected to the upper side of the base plate 4, and a plug-in frame plate 6 for installing the hardware accessories 3 is fixed on the upper side of the rotating table 5. The top surface of the plug-in frame plate 6 is provided with a plug-in slot 61 for corresponding plug-in of the connecting plugs 31. Four limiting rods 62 are movably arranged inside the plug-in frame plate 6 for synchronously clamping the connecting plugs 31 inside each plug-in slot 61.

[0020] Specifically, each pair of limiting rods 62 forms a group and is slidably inserted into the two sides of the insertion slot 61. The inner side of the insertion frame plate 6 is provided with two sets of rectangular sliding plates 63 for mounting each limiting rod 62. Each set of rectangular sliding plates 63 consists of two rods. Therefore, each pair of limiting rods 62 is fixed to opposite sides of each pair of rectangular sliding plates 63. This allows each set of limiting rods 62 to be secured to the two connecting plugs 31 when the rectangular sliding plates 63 move relative to each other. The top and bottom surfaces of the rectangular sliding plates 63 slide against the inner side of the insertion frame plate 6, and the insertion frame plate 6 is equipped with a synchronous drive mechanism for transmitting the relative displacement of the two sets of rectangular sliding plates 63. The synchronous drive structure includes a rotating rod 64 rotatably connected to the inner side of the plug-in frame plate 6. The rotating rod 64 is provided with two sets of transmission threads 65, with each pair of opposite transmission threads 65 forming a set. The two sets of transmission threads 65 are respectively threadedly connected to two sets of rectangular slide plates 63. A drive motor 66 for driving the rotating rod 64 to rotate is installed on the left side of the plug-in frame plate 6. Therefore, the drive motor 66 drives the rotating rod 64 to synchronously drive the two sets of opposite transmission threads 65 to rotate synchronously, realizing the relative displacement of each set of two rectangular slide plates 63. This allows the limiting top rod 62 to clamp the groove line of the connecting plug 31 from the side. This structure is simple, synchronous, and stable in use.

[0021] In this embodiment, hydraulic telescopic rods 41 are hinged to both the front and rear sides of the base plate 4. The telescopic ends of the hydraulic telescopic rods 41 are movably connected to the rotating table 5 and are used to push the rotating table 5 to flip to the right. This can adjust the angle of the hardware accessories 3 that are clamped by the plug-in frame plate 6. It can also flip the entire rotating table 5 and the plug-in frame plate 6 directly above the conveyor belt 7. After the synchronous drive structure is reset, the hardware accessories 3 can slide into the conveyor belt 7 and be directly output outward.

[0022] A horizontal upright plate 42 is installed on the upper left side of the base plate 4. This horizontal upright plate 42 is used to support the left side of the bottom surface of the rotating platform 5 to keep it horizontal. The upper side of the horizontal upright plate 42 is coated with a rubber pad that makes elastic contact with the bottom surface of the rotating platform 5, reducing wear and noise caused by hard contact. L-shaped connecting rods 51 can be detachably connected to both the front and rear sides of the rotating platform 5. The two ends of the L-shaped connecting rods 51 are locked to the rotating platform 5 with screws. The middle part of the L-shaped connecting rods 51 is set downward and is rotatably connected to the telescopic end of the hydraulic telescopic rod 41. The L-shaped connecting rods 51 have different sizes and models, which can be replaced according to the usage requirements, so that the middle part of the L-shaped connecting rods 51 is at different heights. In this way, when the hydraulic telescopic rod 41 extends and extends to push the rotating platform 5, it can be flipped to different angles.

[0023] In practical use, by inserting the connector 31 of the hardware accessory 3 into the insertion slot 61 on the insertion frame plate 6, the drive motor 66 drives the rotating rod 64 to cause the two sets of two opposing transmission threads 65 to respectively drive the two sets of two rectangular sliding plates 63 to move relative to each other. This allows the limiting top rods 62 on both sides of the insertion slot 61 to move relative to each other, pressing against the annular groove of the connector 31 from the side, thus achieving stable clamping of the hardware accessory 3. The engraving and milling machine head 2 then performs milling operations. During this process, the rotating table 5 can be rotated by the hydraulic telescopic rod 41 as needed, thereby allowing the clamped hardware accessory 3 to rotate to the desired position. Milling can be performed at a suitable angle. The base plate 4 can be operated in conjunction with the sliding of the cross slide table to achieve flexible milling. During the processing, the hardware parts 3 can be inserted into the insertion slot 61 in a different direction according to the usage requirements, and the other side can be rotated for processing. After the processing is completed, the hydraulic telescopic rod 41 extends fully, allowing the rotating table 5 and the insertion frame plate 6 to flip over to the top of the conveyor belt 7. At this time, the control limit rod 62 slides synchronously to both sides to disengage from the annular groove of the connecting plug 31, allowing the hardware parts 3 to slide down onto the conveyor belt 7 for external conveying and discharge, thus improving the overall usage effect and efficiency.
