Technical Field

[0001] The utility model belongs to the technical field related to circuit board production, in particular to a micro drill four-station machine grooving mechanism. Background Art

[0002] The drill needle four-station machine is a device used to process micro drill needles, mainly used for micro-hole processing of PCB boards. This equipment usually includes multiple workstations, each of which is responsible for different processing procedures, such as rough grinding, fine grinding, groove grinding, back grinding, and sharpening. The design purpose of the drill needle four-station machine is to improve production efficiency, reduce manual operations, and improve processing accuracy and stability. When it is working, it cuts grooves through a groove cutting mechanism, but it still has the following disadvantages in actual use:

[0003] When the grooving mechanism of the drill needle four-station machine is working, it is usually limited to grooving one circuit board. When facing the grooving requirements of circuit boards of different sizes and models, it is necessary to replace accessories to adapt to the grooving requirements of different circuit boards, which is not convenient to use;

[0004] When the grooving mechanism of the drill needle four-station machine is working, it directly rotates through the grooving to cut grooves on the circuit board along the tangent direction. During the working process, it needs to cut grooves of different shapes many times, and it is not convenient to adjust the grooving position. Utility Model Content

[0005] The purpose of the utility model is to provide a micro drill four-station machine grooving mechanism, which solves the problems that the four-station machine grooving mechanism of the drill is not suitable enough for grooving different circuit boards during operation and the grooving position is not convenient to adjust by setting a fixed seat, a fixed plate, a lifting frame and a supporting seat.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a micro-drill four-station machine slotting mechanism, comprising a fixed seat, a fixed plate, a lifting frame and a support seat, wherein the support seat is arranged at the top center of the fixed seat, and the two short sides of the top of the fixed seat are fixed with a fixed plate, and the two fixed plates are arranged on one side close to each other, and the two short sides of the two movable plates are fixed with a side plate, and the two side plates of the same movable plate are arranged on the one side close to each other. A limiting plate is arranged on the side where the two side plates of the same movable plate are close to each other. A lifting frame is arranged above the fixed seat, and a positioning plate is fixed at a short side of the top of the lifting frame, and a moving frame is arranged on the side of the positioning plate close to the center of the lifting frame, and a driving motor is arranged on the top of the moving frame, and an electric push rod 2 is fixed on the top of the moving frame on one side of the driving motor, and the telescopic end of the electric push rod 2 is fixed to the driving motor. When working, the support seat is supported thereon by the fixed seat, and the circuit board is suspended and supported thereon by the support seat, and the support groove is supported thereon by the fixed plate when working, and the structure for slotting is supported thereon by the lifting frame.

[0008] Furthermore, a movable opening is fixed at the center of the top of the fixing seat, and a plug-in block is fixed at the center of the bottom of the supporting seat. The plug-in block is plugged into the movable opening. When the fixing seat is working, the plug-in block is movably connected through the movable opening.

When the fixed seat is working, the rotating frame is rotated to drive the threaded rod to rotate, so that the positions of the movable plate and the limiting plate are changed during work.

[0010] Furthermore, an electric push rod 1 is fixed on the side of the positioning plate away from the moving frame, and the piston rod of the electric push rod 1 passes through the positioning plate and is fixed to the moving frame. When the positioning plate is working, the electric push rod 1 drives the piston rod to change the position of the moving frame.

[0011] Furthermore, a driving shaft is fixed to the output end of the driving motor, and the driving shaft passes through the moving frame and a limiting plate is fixed on the periphery of the driving shaft at the bottom of the moving frame. The top of the limiting plate is in contact with the bottom of the moving frame. When the driving motor is working, the driving shaft rotates to drive the tool to rotate.

[0012] Furthermore, a tool is fixed to the bottom end of the driving shaft, and a slot is formed on the top of the supporting seat. The width of the slot is greater than the diameter of the tool, so that the tool can slot the circuit board when rotating.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the grooving mechanism of the drill needle four-station machine is not suitable for grooving different circuit boards when working by arranging a fixing seat, a fixing plate and a supporting seat. The shape of the groove on the circuit board to be grooved is determined, and then a suitable supporting seat is selected, and the plug-in block at the bottom of the supporting seat is inserted into the movable hole on the fixing seat, and the work can be started. By placing the circuit board to be processed on the top of the supporting seat on the fixing seat, the rotating frame on the threaded rod connected with the two movable plates is driven to abut against the two ends of the circuit board on the supporting seat under the threaded connection between the threaded rod and the fixing plate, and the rotating frame is rotated again to adjust the position of the circuit board on the supporting seat, and then the rotating frame on the threaded rod outside the side plate is rotated, so that the rotating frame drives the threaded rod to rotate, and the limiting plate is driven to clamp on the circuit board through the rotation of the threaded rod until the position of the circuit board to be grooved is adjusted to correspond to the position of the grooved opening of the supporting seat, and the grooving work can be started. When working, the grooving mechanism of the drill needle four-station machine is more suitable for grooving different circuit boards when working.

[0015] The utility model solves the problem that it is not convenient to adjust the cutting position of the cutting mechanism of the four-station drilling machine by arranging a fixed seat, a lifting frame and a supporting seat. When the circuit board is working, after the structure connected by the fixed plate is clamped on the fixed seat, the lifting structure outside the lifting frame is started to drive the lifting frame to descend to the position where the tool is close to the circuit board for cutting grooves, and then the electric push rod one is started to drive the moving frame to move, and then the driving motor is driven by the electric push rod two until the bottom of the tool is aligned with the top of the circuit board cutting position, and the driving motor can be started, and the driving motor drives the driving shaft to rotate, driving the tool to rotate, and the lifting frame is driven down by the external lifting device, so that when working, the moving frame is pushed to move by the electric push rod one to cut grooves on the circuit board, making it more convenient for the cutting mechanism of the four-station drilling machine to adjust the cutting position.
