Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a fully automatic vertical machining center with automatic feeding. Background Technology

[0002] A vertical machining center (VMC) is a CNC milling machine equipped with a tool magazine and automatic tool changer. CNC is a technology that controls machine tool movements through digital programs. The spindle of a vertical machining center is vertically arranged and is mainly used for precision machining such as milling, drilling, and tapping. It typically features multi-axis linkage, high precision, and automated machining capabilities, belonging to a high-end sub-category of CNC machine tools. Traditionally, vertical machining centers typically use manual loading, requiring operators to manually clamp the workpiece onto the worktable and unload it after machining. This is inefficient and increases safety hazards during large-scale continuous production.

[0003] The publication number CN221474366U discloses a CNC machining center that facilitates automatic feeding. By setting up a feeding component, a vacuum suction cup is used to pick up the material. A servo motor drives an electric push rod to rotate, causing the suction cup to rotate from outside the machine tool to above the machining table. The air pump is then turned off, allowing the material to fall onto the machining table, thus achieving automatic feeding.

[0004] However, in actual use, suction cups are only suitable for adsorbing materials with regular surfaces. After processing, the material surface becomes irregular, making it difficult to be picked up and impossible to achieve automatic feeding. In addition, the height of the suction cup is not adjustable, which has high requirements for the original size of the material and cannot be adapted to materials of different sizes.

[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] Example 1:

[0031] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0032] A fully automated vertical machining center with automatic feeding, comprising:

[0033] Machining center 1, with a horizontal moving component 2 on the side of machining center 1, a gripping component 3 in the middle of the horizontal moving component 2, and two conveyor belts 4 arranged side by side below the gripping component 3, which are used for loading and unloading respectively.

[0034] The conveyor belt 4 can be a metal chain conveyor belt. In practical applications, photoelectric sensors or other devices for detecting the position of workpieces can be installed on the conveyor belt 4 to facilitate the gripping component 3 to grip the materials.

[0035] The machining center 1 includes a frame 11, a machining table 12 is provided on the front side of the top surface of the frame 11, the machining table 12 can move horizontally along its own axis, and a machine head 13 is provided vertically on the rear side of the top surface of the frame 11, the machine head 13 is used for part processing.

[0036] The movement of the machining table 12 is driven by a motor and a lead screw, which is a well-known technology and will not be elaborated here.

[0037] A protective cover 14 is also fixedly installed on the top surface of the frame 11 by bolts. A feeding door 15 is slidably installed on the side of the protective cover 14 through a first linear module 16. The first linear module 16 is used to drive the feeding door 15 to move horizontally.

[0038] The protective cover 14 is used to prevent chips and coolant from splashing.

[0039] The first linear module 16 is driven by a high-precision servo motor and, in conjunction with an encoder, achieves closed-loop control, enabling the loading gate 15 to slide back and forth, thus achieving automatic opening and closing. When the loading gate 15 is closed, it prevents chips and coolant from splashing. When the loading gate 15 is open, it facilitates material loading.

[0040] The horizontal moving component 2 is used to drive the gripping component 3 to move horizontally, thereby driving the material to move between the conveyor belt 4 and the processing center 1.

[0041] The horizontal moving component 2 is located outside the loading gate 15. The horizontal moving component 2 includes a horizontal support 21. A sliding frame 23 is slidably mounted on the top surface of the horizontal support 21 through a second linear module 22. A second sliding frame 25 is slidably mounted on the inner side of the sliding frame 23 through a third linear module 24.

[0042] Both the second linear module 22 and the third linear module 24 are driven by high-precision servo motors and use encoders to achieve closed-loop control. Both the second linear module 22 and the third linear module 24 have two sets of lead screws and two sets of guide rails. The two lead screws rotate synchronously through bevel gears and a drive shaft.

[0043] The second linear module 22 is used to drive the sliding frame 23 to move horizontally, and the third linear module 24 is used to drive the second sliding frame 25 to move horizontally.

[0044] The horizontal support 21 and the sliding frame 23 are U-shaped and their openings face the loading gate 15. The end of the sliding frame 23 can extend beyond the end of the horizontal support 21 and into the protective cover 14.

[0045] After the sliding frame 23 extends into the protective cover 14, the second sliding frame 25 is moved to the head of the sliding frame 23, so that the second sliding frame 25 can be moved into the protective cover 14.

[0046] The gripping component 3 includes a lifting component, which is connected to the horizontal moving component 2. The lifting component is connected to a vacuum suction cup 36. The lifting component is used to drive the vacuum suction cup 36 to move vertically, and the vacuum suction cup 36 is used to pick up materials.

[0047] Vacuum suction cup 36 is made of flexible material and works with negative pressure equipment to suck up materials using vacuum.

[0048] The negative pressure device uses a known vacuum pump. The vacuum suction cup 36 is connected to the vacuum pump via a hose. A solenoid valve needs to be installed on the pipeline to open or close the vacuum passage.

[0049] The lifting assembly includes a first telescopic rod 31, which is fixedly installed at the center of the top surface of the second sliding frame 25. The first telescopic rod 31 passes through the second sliding frame 25 and is fixedly connected to the lifting frame 32 by bolts. The first telescopic rod 31 is used to drive the lifting frame 32 to move in the vertical direction.

[0050] The first telescopic rod 31 can be a servo electric actuator or a hydraulic cylinder. When the first telescopic rod 31 is working, it can drive the lifting frame 32 to move in the vertical direction.

[0051] Both the lifting frame 32 and the second sliding frame 25 adopt a hollow design to reduce weight.

[0052] The lifting frame 32 is vertically slidably mounted with a slide rod 34 via a hydraulic expansion sleeve 33. The slide rod 34 is hollow, and a vacuum suction cup 36 is threadedly installed at the end of the slide rod 34. The pipe of the vacuum suction cup 36 passes through the slide rod 34 and connects to the negative pressure equipment.

[0053] The slide bar 34 is hollow, allowing the connecting hose of the vacuum suction cup 36 to pass through easily, thus protecting the pipeline.

[0054] When the hydraulic expansion sleeve 33 is pressurized, it can expand the space between the side of the slide rod 34 and the lifting frame 32 to fix the slide rod 34. When the hydraulic expansion sleeve 33 is depressurized, the slide rod 34 can slide in the vertical direction.

[0055] The pressure supply to the hydraulic expansion sleeve 33 can be provided by a known hydraulic station and controlled by an electromagnetic control valve, which facilitates automatic control.

[0056] The slide bar 34 allows the vacuum suction cup 36 to adhere to the material surface, making it suitable for irregularly shaped materials.

[0057] The slide bar 34 is threaded with a counterweight 35, which can increase the descent speed of the slide bar 34 and make the vacuum suction cup 36 fit the material surface more closely.

[0058] When the slide bar 34 is fixed, the first telescopic rod 31 works and can drive the slide bar 34 to move through the lifting frame 32, thereby driving the vacuum suction cup 36 to move, thus changing the height of the vacuum suction cup 36 to adapt to materials of different heights. After the vacuum suction cup 36 adsorbs the material, it can drive the material to move.

[0059] Working principle:

[0060] Material feeding stage:

[0061] Using the left-side conveyor belt 4, the billet is transported to below the horizontal support 21. The second linear module 22 and the third linear module 24 are controlled to work, driving the sliding frame 23 and the second sliding frame 25 to move, so that the gripping component 3 moves directly above the billet.

[0062] The first telescopic rod 31 is controlled to work, driving the lifting frame 32 to descend, while the hydraulic tensioning sleeve 33 is controlled to release the slide rod 34.

[0063] After all the vacuum suction cups 36 are in contact with the material surface, the hydraulic expansion sleeve 33 is controlled to fix the slide rod 34, and at the same time, the negative pressure device is used to generate negative pressure so that the vacuum suction cups 36 adsorb the material.

[0064] The first telescopic rod 31 is controlled to work again, driving the lifting frame 32 to rise, and the material is lifted by the vacuum suction cup 36.

[0065] Control the first linear module 16 to work, drive the loading gate 15 to move towards the back of the machining center 1, and open the side of the protective cover 14.

[0066] The control table 12 moves towards the upward material gate 15, and at the same time controls the second linear module 22 and the third linear module 24 to work, driving the sliding frame 23 and the second sliding frame 25 to move, so that the gripping component 3 carries the material to the top of the processing table 12.

[0067] The processing table 12 moves towards the upward material gate 15, which allows the starter head 13 to move.

[0068] After the gripping component 3 moves the material to a predetermined position above the processing table 12, it controls the first telescopic rod 31 to work, drives the lifting frame 32 to descend, so that the material falls onto the processing table 12, disconnects the negative pressure pipeline of the vacuum suction cup 36, and releases the adsorption on the material.

[0069] The first telescopic rod 31 is controlled to work again, driving the lifting frame 32 and vacuum suction cup 36 to rise and move away from the material. Then the second linear module 22 and the third linear module 24 are controlled to work, driving the sliding frame 23 and the second sliding frame 25 to move, so that the gripping component 3, the sliding frame 23 and the second sliding frame 25 exit the protective cover 14.

[0070] Material feeding stage:

[0071] Control the first linear module 16 to work, drive the loading gate 15 to move towards the back of the machining center 1, and open the side of the protective cover 14.

[0072] The control table 12 moves towards the upward material gate 15, and at the same time controls the second linear module 22 and the third linear module 24 to work, driving the sliding frame 23 and the second sliding frame 25 to move, so that the gripping component 3 moves above the processing table 12.

[0073] The first telescopic rod 31 is controlled to work, driving the lifting frame 32 to descend, while the hydraulic tensioning sleeve 33 is controlled to release the slide rod 34.

[0074] After all the vacuum suction cups 36 are in contact with the material surface, the hydraulic expansion sleeve 33 is controlled to fix the slide rod 34, and at the same time, the negative pressure device is used to generate negative pressure so that the vacuum suction cups 36 are adsorbed to the processed workpiece.

[0075] The first telescopic rod 31 is controlled to work again, driving the lifting frame 32 to rise, and the material is lifted by the vacuum suction cup 36.

[0076] Then, the second linear module 22 and the third linear module 24 are controlled to operate, driving the sliding frame 23 and the second sliding frame 25 to move, so that the sliding frame 23, the second sliding frame 25 and the gripping assembly 3 carry the material out of the protective cover 14. And the gripping assembly 3 and the material are moved above the right conveyor belt 4.

[0077] After the gripping component 3 moves the material to a predetermined position above the conveyor belt 4, it controls the first telescopic rod 31 to work, drives the lifting frame 32 to descend, so that the material falls onto the conveyor belt 4, disconnects the negative pressure pipeline of the vacuum suction cup 36, and releases the adsorption on the material.

[0078] The first telescopic rod 31 is activated again, driving the lifting frame 32 and vacuum suction cup 36 to rise and move away from the material. The unloading is then complete.

[0079] After the material falls onto conveyor belt 4, it is transported to the next workstation by conveyor belt 4 on the right side.
