Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a multi-axis linkage CNC machine tool. Background Technology

[0002] Multi-axis linkage CNC machine tools are the core equipment for achieving high-precision machining of complex curved surfaces in modern manufacturing. They significantly improve machining accuracy, efficiency, and flexibility by synchronously controlling the coordinated movement of multiple coordinate axes through a computer numerical control system. They are widely used in high-end manufacturing fields such as aerospace, automobiles, ships, and medical devices.

[0003] However, in the current technology, many CNC machine tools still use manual loading and unloading, which results in low production efficiency and can easily lead to fatigue for workers.

[0004] Therefore, we propose a multi-axis linkage CNC machine tool. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that many existing CNC machine tools still use manual loading and unloading, which results in low production efficiency and easy fatigue for workers. Therefore, a multi-axis linkage CNC machine tool is proposed.

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

[0007] A multi-axis linkage CNC machine tool, comprising:

[0008] The base has a rectangular groove on its surface, and a mounting seat is fixedly connected inside the rectangular groove. A through-hole is punched through the surface of the mounting seat.

[0009] Two first electric push rods are fixedly connected to the inner wall of the bottom of the base, and the output shaft end of the first electric push rod is fixedly connected to the support plate;

[0010] Two material boxes are respectively set on the surface of two support plates. The material boxes have openings of different sizes on opposite sides, and multiple parallel placement plates are fixedly connected to the inner walls of both sides.

[0011] Two conveyor belts are installed in mounting grooves on the surface of the base, and the two conveyor belts feed in opposite directions;

[0012] The material pushing mechanism includes a connecting plate fixedly connected to the surface of the base, a second electric push rod, and a third electric push rod. The second electric push rod is fixedly connected to the connecting plate, and the axis of the third electric push rod forms an angle of ° with the horizontal plane. The output shaft ends of the second and third electric push rods are both fixedly connected to the material pushing plate.

[0013] One possible design also includes:

[0014] Two mounting brackets are fixedly connected to the surface of the base;

[0015] The movable frame is slidably connected between two fixed frames;

[0016] The slide is slidably connected to one side of the movable frame;

[0017] The lifting seat is slidably connected to the bottom of the slide seat;

[0018] The cylinder is fixedly connected to one side of the lifting seat, and the piston rod end is fixedly connected to the stamping head.

[0019] In one possible design, a first motor is fixedly connected to one side of the fixed frame, the output shaft of the first motor is fixedly connected to a first screw, and the first screw thread passes through the movable frame;

[0020] The movable frame is fixedly connected to a second motor at its end, and the output shaft of the second motor is fixedly connected to a second screw, with the thread of the second screw passing through the slide block.

[0021] The top of the slide is fixedly connected to a third motor, and the output shaft of the third motor is fixedly connected to a third screw, with the thread of the third screw passing through the lifting seat.

[0022] In one possible design, a T-shaped positioning plate is fixedly connected to the outside of the material box, and positioning grooves are opened on the inner walls of both sides of the base, with the positioning plate and the positioning grooves fitting together with a clearance.

[0023] In one possible design, two hydraulic cylinders are also included, symmetrically fixed to the surface of the base, with a clamping plate fixedly connected to the end of the piston rod of the hydraulic cylinder, and a pressure sensor embedded on one side of the clamping plate.

[0024] In one possible design, the bottom of the rectangular groove is connected to an arc-shaped discharge groove that extends to the side wall of the base.

[0025] In one possible design, after stamping is completed, a hydraulic cylinder drives a clamping plate to push the workpiece to another conveyor belt, which then feeds the workpiece into a material box. A third electric push rod drives a pusher plate to push the workpiece completely into the material box.

[0026] In this application, during use, a material box containing the workpiece to be processed is placed on the right-side support plate, and an empty material box is placed on the left-side support plate. After the infrared sensor detects the material box, the conveyor belt is started, and simultaneously, the first electric push rod is activated to raise the support plate and material box to a specified height. Then, the second electric push rod is activated to move the pusher plate, which pushes the uppermost workpiece onto the conveyor belt. The conveyor belt moves the workpiece, and when the infrared sensor detects that the workpiece has reached the specified position, the hydraulic cylinder is activated to move the right-side clamping plate to push the workpiece onto the mounting base. Then, the left-side clamping plate is controlled to move to clamp the workpiece, and the pressure sensor monitors the pressure in real time. Force is applied to control the stroke distance of the hydraulic cylinder, ensuring that the clamping force on the workpiece remains within a suitable range. Then, the operation of the first, second, and third motors is controlled, synchronously controlling the cylinder and the stamping head to move in multiple coordinate directions. The cylinder is started to drive the stamping head to stamp the workpiece. The stamped material passes through the stamping through hole and is discharged along the discharge groove. After stamping is completed, the left clamping plate resets, and the right clamping plate continues to push the workpiece to another conveyor belt. The conveyor belt moves the workpiece toward the material box and feeds it into the material box. Then, the third electric push rod is started to drive the pusher plate to move, pushing the workpiece completely into the material box. The above steps are repeated.

[0027] Beneficial effects: In this utility model, the multi-axis linkage CNC machine tool, through the setting of structures such as push plate, second electric push rod and material box, can automatically complete the loading and unloading of multiple workpieces, saving the energy of the staff and improving work efficiency;

[0028] In this utility model, the multi-axis linkage CNC machine tool, through the setting of positioning grooves, positioning plates and support plates and other structures, makes it convenient for people to replace material boxes, and the operation is simple and convenient.

[0029] In this utility model, the multi-axis linkage CNC machine tool, through the arrangement of a first motor, a second motor and a third motor, can synchronously control the coordinated movement of multiple coordinate axes through a computer numerical control system, thus ensuring the machining accuracy.
