Description

Technical Field

[0001] This utility model belongs to the technical field of PIN pin processing equipment, specifically relating to a milling machine for PIN pin processing. Background Technology

[0002] Pins are typically used in connectors to perform conductive transmission. Pin processing sometimes involves using relatively hard materials. When milling or rounding these materials, a large clamping force is required. Insufficient clamping force can cause the pins to wobble or rotate during processing, reducing the product yield. Furthermore, some special pin blanks have a structure where one end is thicker than the other, or they have undergone previous processing, necessitating optimization of the relative positions of the pins during material handling, clamping, and milling. Therefore, it is necessary to design a pin milling machine capable of handling these processing requirements. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a milling machine for PIN processing. This machine can improve the clamping force of the clamping device, prevent the PIN from swinging or rotating during processing due to incomplete clamping, and also meet the processing requirements of PINs with special structures in the blank.

[0004] This utility model is achieved through the following technical solution:

[0005] A milling machine for PIN pin processing includes a machine base, characterized in that: a material storage device and a clamping device are arranged side by side on the left and right sides of the rear part of the machine base, and a transverse transmission track is provided at the front part; a transverse slide is provided on the transverse transmission track, and a gripping robot and a milling device are installed on the left and right sides of the transverse slide; the gripping robot is provided with a drive motor for driving the robot arm to move back and forth, and a cylinder for opening and closing the robot fingers; the clamping device includes a cavity, a chuck, and a clamping drive motor; the chuck has a three-jaw shaped gripper at the front part and a positioning groove running back and forth on the outer edge of the rear part; the outer edge of the gripper has a conical surface structure; when the chuck is pulled backward by the clamping drive motor, the conical surface of the gripper is squeezed by the cavity to clamp the workpiece; the cavity is also equipped with a positioning block that engages with the positioning groove; the machine base is also provided with a receiving box.

[0006] Furthermore, the storage device is provided with a Y-axis slide at the bottom, and a Z-axis slide is mounted on the frame above the Y-axis slide. A storage plate for storing workpieces to be processed is installed on the Z-axis slide.

[0007] Furthermore, the transverse transmission track and the transverse slide are equipped with position sensors. The position sensors detect the position of the transverse slide, thereby controlling the sliding stroke and dwell time of the transverse slide.

[0008] Furthermore, a cable chain is provided between the transverse slide and the machine base.

[0009] Furthermore, a control box is also installed on the machine base, which controls and adjusts the operating parameters of all drive motors and mechanical finger opening and closing cylinders on the machine base.

[0010] The beneficial effects of this utility model are as follows: The milling machine for PIN processing designed in this utility model has a three-jaw shaped clamp for clamping the workpiece, which can improve the clamping force of the clamping device of the milling machine and prevent the PIN from swinging or rotating during processing due to incomplete clamping, thereby improving the milling machine's ability to process hard materials; the position design of the material storage, material retrieval, clamping and milling station ensures that the material storage and clamping devices are on the same side, which is convenient for processing PINs with asymmetrical structures or secondary processing of the blank material itself.

Detailed Implementation

[0016] The technical solution of this utility model will be further illustrated below with specific examples and accompanying drawings.

[0017] like Figures 1-4As shown, a milling machine for PIN pin processing includes a machine base 1. A storage device 2 and a clamping device 6 are arranged side-by-side on the rear left and right sides of the machine base 1, and a transverse transmission track 3 is provided at the front. A Y-axis slide 21 is provided below the storage device 2, and a Z-axis slide 22 is mounted on a frame above the Y-axis slide 21. A storage plate 23 for storing workpieces to be processed is installed on the Z-axis slide 22. A transverse slide 4 is provided on the transverse transmission track 3, and a gripping robot 5 and a milling device 7 are installed on the transverse slide 4 on the left and right sides. A drag chain is provided between the transverse slide 4 and the machine base 1. The gripping robot 5 is equipped with a drive motor for moving the robotic arm back and forth, and a cylinder for opening and closing the robotic fingers; the clamping device 6 includes a cavity, a chuck 61, and a clamping drive motor 62. The chuck 61 has a three-jaw shaped gripper 611 at the front and a positioning groove 612 running back and forth on its outer rear edge; the outer edge of the gripper 611 has a conical surface structure. When the chuck 61 is pulled backward by the clamping drive motor 62, the conical surface of the gripper 611 is squeezed by the cavity and clamps the workpiece. The cavity is also equipped with a positioning block that is inserted into the positioning groove 612; the machine base 1 is also equipped with a receiving box 8.

[0018] The transverse transmission track 3 and the transverse slide 4 are equipped with position sensors. The position sensors detect the position of the transverse slide 4, thereby controlling the sliding stroke and dwell time of the transverse slide 4.

[0019] The machine tool is also equipped with a control box 9, which controls and adjusts the operating parameters of all drive motors and mechanical finger opening and closing cylinders on the machine tool 1.

[0020] When it works, such as Figures 1-4The PIN pins to be processed are stored on the storage plate 23. The height of the storage plate 23 is adjusted by the Z-axis slide 22 so that the gripping robot 5 always grips the PIN pins to be processed on the storage plate 23 at the same height. The gripping robot 5 picks up the PIN pins to be processed from the storage plate 23, and then slides them on the transverse transfer track 3 and transverse slide 4 until the gripping robot 5 is aligned with the chuck 61 of the clamping device 6. The chuck 61 is initially in the open state (the three-jaw chuck 61 is naturally open). Then, the clamping drive motor 62 is activated, pulling the chuck 61 slightly backward through the lead screw. The conical structure on the outer edge of the jaw 611 is squeezed by the cavity and clamps the PIN pins to be processed. The cavity of the clamping device 6 is equipped with a positioning block that is inserted into the positioning groove 612. Due to the restriction of the positioning groove 612, the chuck 61 will not rotate, so the part of the PIN pin being processed is relatively fixed. Then, the gripping robot 5 opens its fingers to release the PIN pins, while the robot arm retracts. The lateral slide 4 slides to the milling device 7, aligning with the clamping device 6. During the sliding process, the milling head of the milling device 7 flattens the PIN pins clamped by the clamping device 6. Then, the lateral slide 4 continues to slide, and the gripping robot 5 clamps the chuck 61 of the clamping device 6 again. The chuck 61 of the clamping device 6 releases the processed PIN pins, and the gripping robot 5 removes the processed PIN pins and releases them into the receiving box 8. Then, the gripping robot 5 returns to the storage plate 23 to grip the PIN pins to be processed, and this process is repeated. For blanks with asymmetrical structures, such as one end being thicker than the other, or for PINs that have undergone secondary processing, the more regular and thicker end is inserted into the slot of the storage plate 23. This makes it easier for the PINs to be processed to be stored in the storage plate 23 and less likely to fall off. After being conveyed by the transverse slide 4, since the storage plate 23 and the clamping device 6 are on the same side, the more regular and thicker end is inserted into the chuck 61 of the clamping device 6 again, making the PIN clamping more stable and preventing the PINs from swinging or rotating during processing due to incomplete clamping.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
