Detailed Description of the Embodiment

[0022] The following will describe in detail a numerically controlled lathe automatic loading and unloading manipulator provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0023] As Figure 1 - Figure 3 shown, an embodiment of the present utility model provides a numerically controlled lathe automatic loading and unloading manipulator, including: a movable seat 1, movably connected to one side of the numerically controlled lathe, which can be adjusted in position according to processing requirements to ensure that the manipulator can cover multiple processing areas of the lathe, and can perform lifting activities through a lifting device. The lifting device adopts a gear and rack mechanism or controls the lifting of the movable seat 1 through a telescopic cylinder. A rotating seat 2 is provided at the bottom of one side of the movable seat 1, and a positioning sleeve 3 is provided at the bottom of the rotating seat 2; a rotating shaft 11, with a support seat 12 provided at the top, the rotating shaft 11 is rotatably connected to the positioning sleeve 3 in a matching manner, and the support seat 12 is rotatably connected to the rotating seat 2 through a bearing 10 in a matching manner; a fixed seat 4, fixed to the bottom of the rotating shaft 11, a cavity is opened at the bottom of the fixed seat 4, and a threaded rod 14 is rotatably connected inside the cavity; a slider 15, threadedly connected to the threaded rod 14 in a matching manner, the bottom of the slider 15 is connected to a pneumatic gripper 7 through an extension rod 16, the slider 15 is entirely located inside the cavity at the bottom of the fixed seat 4, and is slidably connected to the cavity of the fixed seat 4 in a matching manner.

[0024] Through the cooperation of the rotating seat 2, the positioning sleeve 3 and the rotating shaft 11, a stable and flexible rotational connection is achieved, facilitating driving the pneumatic gripper 7 to perform precise flipping movements, and cooperating with the pneumatic gripper 7 slidably connected to the fixed seat 4 to achieve automatic loading and unloading of the workpieces on the numerically controlled lathe, thereby completing the end-face clamping and replacement of the workpieces.

[0025] As Figure 1As shown in the figure, it further includes a rotation drive assembly 5, which is located above the rotating seat 2 and fixed on the side wall of the movable seat 1. At the center position of the top of the support seat 12, there is a mounting seat 13 for cooperating with the output end of the rotation drive assembly 5 to be connected. Among them, the rotation drive assembly 5 can adopt components such as direct drive by a servo motor, a servo motor cooperating with a reduction box, or a rotary cylinder, aiming to drive the fixed seat 4 to make a cyclic reciprocating 180° flipping motion.

[0026] As Figure 2 shown in the figure, an installation groove 8 is opened at the top of the rotating seat 2. The installation groove 8 is internally connected to the positioning sleeve 3, and a boss 9 is provided at the bottom of the installation groove 8. The boss 9 protrudes from the inner side wall of the installation groove 8. The bearing 10 is a flat thrust ball bearing 10, and both sides are respectively abutted against the bottom of the support seat 12 and the top of the boss 9.

[0027] Using the flat thrust ball bearing 10 as the connecting piece between the support seat 12 and the rotating seat 2 effectively reduces the friction and wear during the rotation process, improves the durability and service life of the manipulator. The design of the boss 9 further enhances the contact area between the installation groove 8 and the bearing 10, improves the stability of the connection, and prevents loosening problems caused by vibration or impact.

[0028] As Figure 3 shown in the figure, it further includes a driving motor 6, which is fixed on the outer side of one end wall of the fixed seat 4. The output end of the driving motor 6 passes through the end wall of the fixed seat 4 and is connected to the threaded rod 14 for driving the threaded rod 14 to rotate. It further includes two guide rods 17, which are arranged on both sides of the threaded rod 14. The two guide rods 17 are arranged parallel to the threaded rod 14 and fixedly connected to both end walls of the fixed seat 4.

[0029] The driving motor 6 is fixed on the fixed seat 4. By driving the rotation of the threaded rod 14, using the principle of screw drive, it pushes the slider 15 to make a linear reciprocating movement in the cavity of the fixed seat 4. This design realizes the precise control of the pneumatic gripper 7 in the vertical direction, and can accurately grasp and place workpieces at different heights. At the same time, the setting of the guide rods 17 ensures the stability of the slider 15 during the movement process, preventing grasping failure or workpiece damage caused by deviation.

[0030] In the technical solution provided by the present utility model, during actual operation, according to the size, position and processing requirements of the workpiece to be processed, the initial position of the movable seat 1 on one side of the numerical control lathe is adjusted to ensure that the manipulator can cover the required processing area; the lifting device (such as a rack and pinion mechanism or a telescopic cylinder) is controlled by the numerical control system to lower the movable seat 1 and the entire manipulator to an appropriate height so that the pneumatic gripper 7 can approach the workpiece, and the pneumatic gripper 7 is activated to open it by supplying air from the air source; subsequently, the rotation drive assembly 5 (such as a servo motor, a servo motor combined with a reduction box or a rotary cylinder) is activated to drive the fixed seat 4 and the pneumatic gripper 7 to perform an accurate flipping motion around the rotating shaft 11 until the pneumatic gripper 7 is aligned with the workpiece, and the drive motor 6 is activated to make the pneumatic gripper 7 approach the lathe chuck and clamp the workpiece. After the pneumatic gripper 7 clamps the workpiece, the drive motor 6 drives the pneumatic gripper 7 to reset, and then the rotation drive assembly 5 drives the fixed seat 4 and the pneumatic gripper 7 as a whole to perform a flipping motion. Subsequently, the drive motor 6 is started again to make the pneumatic gripper 7 drive the workpiece to approach the lathe chuck. After the chuck clamps the workpiece, the manipulator resets. It should be specifically noted that during the process of the manipulator performing loading and unloading work alone, it only needs to cooperate with the movable seat 1 and the drive motor 6 to complete, and there is no need to cooperate with the rotation drive device.

[0031] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components and circuits are not described in detail.

[0032] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
