Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an automated loading and unloading CNC machining equipment. Background Technology

[0002] Currently, in the CNC machining industry, most companies still manually fix semi-finished workpieces onto fixtures for processing, resulting in long machine downtime, requiring a large number of operators, and low efficiency. This increases labor costs and reduces competitiveness. Existing patents, such as Chinese patent application number 202210779175.1, disclose an automated loading and unloading device for CNC machine tools. This device includes a movable support mechanism located at the front of the machine tool, a rotating mechanism mounted on the movable support mechanism for rotating and switching workpieces, a gripping mechanism for grasping and placing workpieces on the rotating mechanism, and a feeding mechanism located at the front of the movable support mechanism for conveying workpieces. The gripping mechanism is connected to the rotating mechanism, and the rotating mechanism is connected to the movable support mechanism. The movable support mechanism includes a base with a column at its upper end. This patent document describes a process where a feeding mechanism synchronously transports workpieces, while a moving support mechanism, a rotating mechanism, and a gripping mechanism intermittently grip, rotate, and move the raw materials and workpieces for loading and unloading. This continuous processing, while improving machine tool efficiency to some extent, still results in low overall efficiency and difficulty in ensuring workpiece stability and positional accuracy during processing. Therefore, the shortcomings are significant, necessitating a solution. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an automated loading and unloading CNC machining equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated CNC machining equipment for loading and unloading materials includes a CNC machine tool, a worktable mounted on the table of the CNC machine tool, a receiving box located on one side of the worktable, a clamping mechanism located on the worktable, an unloading robot movably mounted inside the CNC machine tool, a base located on one side of the CNC machine tool, a feeding mechanism mounted on the base, an loading robot mounted on the base and located on one side of the feeding mechanism, a storage platform located on the other side of the worktable for storing pressure frame parts, and a pick-and-place robot movably mounted inside the CNC machine tool. The pick-and-place robot is used to pick up and place pressure frame parts. The loading robot is movably mounted above the discharge end of the feeding mechanism and above the worktable, and the unloading robot is movably mounted above the worktable and the receiving box. The top surface of the worktable is provided with a bearing cavity for holding workpieces. When the pressure frame parts are placed on the workpieces held in the bearing cavity, the clamping mechanism presses the pressure frame parts firmly onto the worktable, and the cutting tools of the CNC machine tool are used to process the workpieces.

[0006] Furthermore, the clamping mechanism includes two clamping assemblies respectively installed on the worktable, with the two clamping assemblies located on both sides of the bearing cavity.

[0007] Furthermore, the clamping assembly includes a corner pressing cylinder installed on the bottom of the worktable and a pressing block installed on the output end of the corner pressing cylinder. The output end of the corner pressing cylinder moves through the worktable, and the pressing block is movably positioned above the worktable.

[0008] Furthermore, there are multiple bearing cavities and multiple pressing mechanisms, with each bearing cavity corresponding to one of the multiple pressing mechanisms.

[0009] Furthermore, multiple bearing cavities are arranged in a rectangular array, and in two adjacent rows of bearing cavities, two adjacent bearing cavities share a single clamping assembly.

[0010] Furthermore, the feeding mechanism includes a vibrating plate mounted on the base, a material rail connected to the discharge port of the vibrating plate, and a receiving seat set at the discharge end of the material rail.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the feeding mechanism supplies the workpiece to a preset position. The loading robot picks up the workpiece supplied by the feeding mechanism and places it in the bearing cavity of the worktable. The bearing cavity initially positions the workpiece. Then, the pick-and-place robot picks up the pressure frame on the storage frame and places it on the workpiece in the bearing cavity, so that the pressure frame covers the edge of the workpiece. Then, the clamping mechanism clamps the pressure frame onto the worktable, pressing the edge of the workpiece. Next, the CNC machine tool's cutting tool processes the workpiece. After processing, the clamping mechanism releases the pressure frame, the pick-and-place robot picks up the pressure frame and places it on the storage table. The storage table stores the pressure frame. Finally, the unloading robot picks up the processed workpiece and places it into the receiving box. This utility model can realize automated loading, processing, and unloading of workpieces, with a high degree of automation, improving the efficiency of workpiece processing.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figs. 1 to 4 As shown, this utility model provides an automated loading and unloading CNC machining equipment, which includes a CNC machine tool 1, a worktable 2 mounted on the table of the CNC machine tool 1, a receiving box 3 located on one side of the worktable 2, a clamping mechanism 4 located on the worktable 2, an unloading robot 5 movably mounted inside the CNC machine tool 1, a base 6 located on one side of the CNC machine tool 1, a feeding mechanism 7 mounted on the base 6, an loading robot 8 mounted on the base 6 and located on one side of the feeding mechanism 7, a storage table 9 located on the other side of the worktable 2 for storing the pressing frame 11, and a movable... A pick-and-place robot 10 is movably installed inside the CNC machine tool 1. The pick-and-place robot 10 is used to pick up and place the pressure frame 11. A loading robot 8 is movably installed above the discharge end of the feeding mechanism 7 and the worktable 2. A unloading robot 5 is movably installed above the worktable 2 and the receiving box 3. The top surface of the worktable 2 is provided with a bearing cavity 12, which is used to hold the workpiece 13. After the pressure frame 11 is placed on the workpiece 13 held in the bearing cavity 12, the clamping mechanism 4 clamps the pressure frame 11 onto the worktable 2. The cutting tool of the CNC machine tool 1 is used to process the workpiece 13. Specifically, the CNC machine tool 1 can be a milling machine, a drilling machine, etc., which will not be described in detail here.

[0024] In practical applications, the feeding mechanism 7 supplies the workpiece 13 to a preset position. The loading robot 8 picks up the workpiece 13 supplied by the feeding mechanism 7 and places the workpiece 13 in the bearing cavity 12 of the worktable 2. The bearing cavity 12 performs preliminary positioning of the workpiece 13. Then, the pick-and-place robot 10 picks up the pressure frame 11 on the storage ring and places the pressure frame 11 on the workpiece 13 carried by the bearing cavity 12, so that the pressure frame 11 covers the edge of the workpiece 13. Then, the clamping mechanism 4 clamps the pressure frame 11 on the worktable 2, and the pressure frame 11 clamps the edge of the workpiece 13. Then, the tool of the CNC machine tool 1 processes the workpiece 13. After processing, the clamping mechanism 4 releases the pressure frame 11, the pick-and-place robot 10 picks up the pressure frame 11 and places the pressure frame 11 on the storage table 9. The storage table 9 stores the pressure frame 11. Then, the unloading robot 5 picks up the processed workpiece 13 and puts it into the receiving box 3. This utility model can realize automated feeding, processing and unloading of workpiece 13. It has a high degree of automation and improves the efficiency of processing workpiece 13. Furthermore, by adding a pressure frame 11 to press and fix workpiece 13, the positional accuracy and stability of workpiece 13 are improved, thereby improving the quality of processed workpiece 13.

[0025] Specifically, the CNC machine tool 1 is provided with an outer cover 25, and the outer cover 25 is provided with a through hole, through which the loading robot 8 extends into the CNC machine tool 1.

[0026] In this embodiment, the clamping mechanism 4 includes two clamping components 14 respectively installed on the worktable 2, with the two clamping components 14 located on both sides of the bearing cavity 12. In practical applications, the two clamping components 14 clamp the two ends of the clamping frame 11, improving the stability of clamping the clamping frame 11, and thus further ensuring the stability of the workpiece 13.

[0027] In this embodiment, the clamping assembly 14 includes a corner pressing cylinder 15 installed on the bottom of the workbench 2 and a pressing block 16 installed on the output end of the corner pressing cylinder 15. The output end of the corner pressing cylinder 15 movably passes through the workbench 2, and the pressing block 16 is movably disposed above the workbench 2.

[0028] In practical applications, under normal conditions, the piston rod of the corner pressing cylinder 15 is in the extended state, and the pressing block 16 is located outside the bearing cavity 12. When the pressing frame 11 is placed on the edge of the workpiece 13, the corner pressing cylinder 15 is activated. The corner pressing cylinder 15 first drives the pressing block 16 to rotate at a preset angle, so that the pressing block 16 is located above the edge of the workpiece 13. Then, the corner pressing cylinder 15 drives the pressing block 16 to descend, so that the pressing block 16 presses the pressing frame 11.

[0029] In this embodiment, there are multiple bearing cavities 12 and multiple clamping mechanisms 4, with each bearing cavity 12 corresponding to one of the multiple clamping mechanisms 4. This structural design enables multiple workpieces 13 to be clamped at one time, improving the efficiency of workpiece processing.

[0030] In this embodiment, multiple bearing cavities 12 are arranged in a rectangular array. In two adjacent rows of bearing cavities 12, two adjacent bearing cavities 12 share a single clamping assembly 14, which reduces the number of clamping assemblies 14, simplifies the structure, makes the structure compact, and reduces costs.

[0031] In this embodiment, the feeding mechanism 7 includes a vibratory feeder 17 mounted on the base 6, a feed rail 18 connected to the discharge port of the vibratory feeder 17, and a receiving seat 19 disposed at the discharge end of the feed rail 18. In practical applications, a large number of workpieces 13 to be processed are placed in the vibratory feeder 17. The vibratory feeder 17 operates to drive the workpieces 13 to move along the feed rail 18, so that the workpieces 13 on the feed rail 18 move one by one to the receiving seat 19. The loading robot 8 loads the workpieces 13 carried by the receiving seat 19 into the bearing cavity 12.

[0032] In this embodiment, the feeding mechanism 7 includes a translation driver 20 mounted on the base 6, and a receiving seat 19 mounted on the translation end of the translation driver 20. One end of the receiving seat 19 is recessed with a receiving cavity for communicating with the discharge port of the material rail 18, and the other end of the receiving seat 19 is provided with a sealing surface 21 for blocking the discharge port of the material rail 18. Specifically, the translation driver 20 can be a cylinder. In practical applications, when the receiving cavity of the receiving seat 19 corresponds to and communicates with the discharge port of the material rail 18, the workpiece 13 on the material rail 18 moves to the receiving cavity. Then, the translation driver 20 drives the receiving seat 19 to move closer to the loading robot 8, so that the receiving seat 19 moves the workpiece 13 to the loading position. At the same time, the sealing surface 21 of the receiving seat 19 blocks the discharge port of the material rail 18 to ensure that the material rail 18 can supply workpieces 13 one by one. This structural design facilitates the loading robot 8 to pick up the workpieces 13.

[0033] In this embodiment, the storage platform 9 is provided with a storage cavity 22, which is used to store the pressure frame 11. The storage cavity 22 stores the pressure frame 11, ensuring the stability and positional accuracy of the pressure frame 11.

[0034] In this embodiment, the table of the CNC machine tool 1 is provided with a fixing frame 23, and the receiving box 3 is detachably installed in the fixing frame 23. The fixing frame 23 fixes the receiving box 3, making it easy to assemble and disassemble the receiving box 3.

[0035] In this embodiment, the base 6 is equipped with a controller 24, and the clamping mechanism 4, CNC machine tool 1, feeding mechanism 7, loading robot 8, unloading robot 5, and pick-and-place robot 10 are all electrically connected to the controller 24. The controller 24 facilitates the operator's control of the machine.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
