Description

Technical Field

[0001] The utility model specifically relates to the technical field of full-automatic machining centers, in particular to a full-automatic machining center. Background Art

[0002] The fully automatic machining center is a highly automated machine tool equipment, which plays an extremely important role and has a wide range of applications. It controls the motion trajectory and processing parameters of the tool through pre-written programs to achieve precise processing of the workpiece. Usually, the operator inputs the designed processing program into the control system. The system will drive the motor, lead screw and other components according to the program instructions, so that the tool can perform cutting, drilling, milling and other operations according to the predetermined path and speed. High precision: It can achieve very high processing accuracy and meet the needs of industries with strict requirements on product quality. For example, in the aerospace field, the accuracy of parts directly affects the performance and safety of aircraft. High efficiency: It can process continuously and automatically, greatly shortening the production cycle and improving production efficiency. For example, the large-scale production of automotive parts can quickly produce a large number of high-quality parts. High automation: It reduces manual intervention and labor intensity, and also reduces errors caused by human factors. Multi-function: It can complete a variety of complex processing processes, such as milling, drilling, boring, tapping, etc.

[0003] However, when the clamps of the conventional machining center clamp the workpiece, it is usually necessary to effectively clamp the raw material of the workpiece. In this way, when the top of the workpiece is processed, the clamping device will affect the stroke of the tool, and it is impossible to effectively ensure that the tool reaches the processing position. In addition, when the workpiece is placed, the plate-shaped raw material may be installed upside down. In this way, during processing, the machining center cannot effectively ensure the precise processing of the workpiece, resulting in the scrapping of the raw material and the damage of the machining tool, which greatly reduces the machining efficiency of the machining center.

[0004] After searching, Chinese patent publication number CN202221970018.0 discloses a fully automatic mold processing center; it includes support plates arranged at both ends of the upper side of the processing table, the upper ends of the two support plates are respectively provided with Z-axis slide rails, the upper ends of the two Z-axis slide rails are respectively provided with first electric sliders, an X-axis slide rail is installed between the two first electric sliders, a second electric slider is provided on the surface of the X-axis slide rail, an L-shaped support plate is fixedly connected to the front end of the second electric slider, a cylinder is installed on the upper side of the L-shaped support plate, the cylinder lifting shaft slides and extends to the lower end of the L-shaped support plate and is fixedly connected to a processing box, a processing part is installed at the lower end of the processing box, and a rotating clamping part is installed between the two support plates

[0005] When the machining center in the above patent processes the workpiece, although the X-axis slide rail and the Z-axis slide rail can be used to drive the second electric slide block to slide effectively and realize the movement of the workpiece, when the workpiece in the above patent is clamped, the clamping plate is driven by the telescopic rod to clamp effectively. When the size of the workpiece is smaller than the two clamping plates, the two ends of the workpiece will be blocked after the workpiece is fixed, and the tool cannot effectively process the two ends. In addition, the motor and the mounting plate in the above patent are suspended, so the workpiece to be processed cannot be effectively supported when the workpiece is installed.

[0006] In view of the above situation, we provide a fully automatic machining center. In this device, a clamp is fixedly installed on the horizontal slide of the X-axis moving component, a base plate is installed on the base through multiple support columns, and different numbers of positioning pins are arranged at both ends of the base plate. In this way, when the placement plate is placed, the situation of upside-down installation can be effectively avoided, and then the upper positioning frame and the lower positioning frame on the base plate are used for effective support to ensure the stability of the placement plate during processing. During processing, the position of the processing tool and the clamp is effectively adjusted through the cooperation between the X-axis moving component, the Y-axis moving component and the Z-axis moving component, ensuring that during the processing, the processing tool can realize one-time processing and forming of the placement frame, ensuring the processing accuracy, and greatly improving the working efficiency of the machining center.
