Description

Technical Field

[0001] This utility model relates to the field of CNC drilling and milling machine technology, and in particular to a material unloading device for CNC drilling and milling machines. Background Technology

[0002] A drilling and milling machine is a machine tool that integrates drilling, milling, boring, and grinding, and is used for processing small and medium-sized parts. When processing a workpiece, rough machining is usually performed first, followed by finish machining of the workpiece surface to improve the accuracy of the finished product.

[0003] Chinese patent publication number CN220862790U discloses a "material stripping device for CNC drilling and milling machine production". This device, consisting of a lifting plate and fixed cylinders, supplies power to an electromagnetic block when stripping is required. This magnetizes the electromagnetic block, attracting a permanent magnet block and causing it to move upwards. This, in turn, drives the lifting plate and multiple fixed cylinders upwards, pushing the circuit board upwards for rapid stripping. Simultaneously, a drive motor is activated, rotating a worm gear. The meshing of the worm gear and worm wheel drives multiple transmission shafts to rotate synchronously, which in turn drives a drive sprocket. Through a transmission chain, a driven sprocket rotates, which in turn drives a transfer roller in conjunction with a rotating shaft. This allows for rapid transfer and unloading of the circuit board, significantly improving stripping efficiency and quality, and making it easy to use.

[0004] However, the aforementioned patent cannot control the upward movement of the lifting plate, and consequently cannot control the upward movement of the multiple sets of fixed cylinders. This could lead to the circuit board falling due to the excessive upward movement speed of the multiple sets of fixed cylinders. Therefore, we propose a CNC drilling and milling machine unloading device to solve the aforementioned problems. Utility Model Content

[0005] This utility model proposes a material unloading device for a CNC drilling and milling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CNC drilling and milling machine unloading device includes a worktable. Multiple sets of placement slots are provided on the upper surface of the worktable. A circuit board body is provided inside each of the multiple sets of placement slots. A set of through holes is opened on the lower surface of each of the multiple sets of placement slots. Unloading components are provided inside the multiple sets of through holes.

[0008] The unloading assembly includes multiple sets of push rods, which are respectively inserted into multiple sets of through holes. A push plate is provided on the lower end surface of the multiple sets of push rods, and a pusher is provided on the lower end surface of the push plate.

[0009] Preferably, the pushing component includes a fixed plate disposed on one side below the pushing plate. A drive motor is mounted on the side wall of the fixed plate. The output end of the drive motor is connected to a rotating rod. A disc is sleeved on the outer side of the rotating rod. The rotating rod is connected to the upper side wall of the disc. A circular groove is formed on the side wall of the disc. A rotating wheel is engaged with the lower side wall of the circular groove. A lifting block is rotatably connected to one side of the rotating wheel. A lifting rod is disposed on the upper end surface of the lifting block. A lifting plate is disposed on the upper end surface of the lifting rod. The upper end surface of the lifting plate is connected to the lower end surface of the pushing plate.

[0010] Preferably, a support rod is provided on the upper end face of the fixing plate, and a cylinder is provided on the other end face of the support rod. The cylinder is slidably sleeved on the outer side wall of the lifting rod, and a buffer spring is provided on the lower end face of the cylinder. The buffer spring is sleeved on the outer side of the lifting rod, and the lower end of the buffer spring is connected to the upper end face of the lifting block.

[0011] Preferably, a limiting block is provided on the side wall of the cylinder, a limiting rod is provided on the limiting block, and a slider is slidably sleeved on the outer side of the limiting rod, the slider being connected to the outer wall of the lifting block.

[0012] Preferably, a set of support legs is provided at each of the four corners of the lower end face of the workbench.

[0013] Preferably, a connecting block is provided on one side wall of the fixing plate, and a connecting rod is provided on the other end face of the connecting block. The two ends of the connecting rod are respectively connected to the side walls of the two sets of support legs.

[0014] Preferably, a set of damping springs is provided on the inner wall of the bottom end of each of the multiple sets of push rods, and a set of sliding plates is provided on the upper end surface of each of the multiple sets of damping springs. The multiple sets of sliding plates are slidably disposed on the inner wall of the multiple sets of push rods, and a set of top rods is provided on the upper end surface of each of the multiple sets of sliding plates. The upper end surface of each of the multiple sets of top rods slides through the upper end wall of the push rod and extends to the outer side of the push rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] This CNC drilling and milling machine unloading device, through the unloading assembly consisting of multiple sets of push rods, push plates, and push components, can drive the push plate upward by starting the drive motor. The push plate then drives multiple sets of push rods upward. At the same time, by controlling the speed and switch of the drive motor, the upward speed and position of the push rods can be controlled. This avoids the problem of the circuit board being pushed off due to the inability to control the upward position of multiple sets of fixed cylinders, which could be caused by the upward speed of the multiple sets of fixed cylinders being too fast.

A lifting rod 14 is provided on the upper surface of the lifting block 13. A lifting plate 15 is provided on the upper surface of the lifting rod 14. The upper surface of the lifting plate 15 is connected to the lower surface of the pushing plate 6. A support rod 16 is provided on the upper end face of the fixed plate 7, and a cylinder 17 is provided on the other end face of the support rod 16. The cylinder 17 is slidably sleeved on the outer wall of the lifting rod 14. A buffer spring 18 is provided on the lower end face of the cylinder 17, and the buffer spring 18 is sleeved on the outer side of the lifting rod 14, with the lower end of the buffer spring 18 connected to the upper end face of the lifting block 13.

A slider 21 is slidably sleeved on the outer side of the limit rod 20, and the slider 21 is connected to the outer wall of the lifting block 13.

[0028] In this embodiment, after the circuit board bodies 3 inside the multiple placement slots 2 are processed, the drive motor 8 is started. The drive motor 8 drives the rotating rod 9 to rotate, the rotating rod 9 drives the disc 10 to rotate, the disc 10 drives the rotating wheel 12 to move upward through the circular groove 11, the rotating wheel 12 drives the lifting block 13 to move upward, the lifting block 13 drives the lifting rod 14 to move upward, and while the lifting block 13 moves upward, it drives the slider 21 to slide outside the limiting rod 20, which limits the lifting of the lifting block 13.

When the multiple sets of push rods 5 move upward, they drive the multiple sets of top rods 26 to move upward. When the multiple sets of top rods 26 move upward, they can be squeezed by the circuit board body 3. The top rods 26 squeeze the damping springs 24. Under the elastic action of the damping springs 24, they can assist in pushing the circuit board body 3, further improving the working efficiency of unloading the circuit board body 3.
