Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a CNC machining center with a precision feeding mechanism. Background Technology

[0002] A CNC machining center is a program-controlled automated machine tool. This control system can logically process programs with control codes or other symbolic instructions, decode them through a computer, and thus enable the machine tool to perform the prescribed actions. It processes raw materials into finished parts through cutting tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in one clamping through an automatic tool changer, realizing multiple machining functions.

[0003] When using a CNC machining center to process rectangular plates, positional deviations may occur during the feeding process, leading to problems such as tilting of the rectangular plates. This can affect the processing accuracy of the rectangular plates and even cause the raw materials to be scrapped, seriously affecting the normal operation of the CNC machining center.

[0004] To address these issues, we propose a CNC machining center with a precision feeding mechanism. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figs. 1-3 As shown, this utility model embodiment proposes a CNC machining center with a precision feeding mechanism, comprising:

[0023] The CNC machining center 1 is a mature existing technology that can process workpieces into finished parts through cutting tools. Multiple placement bases are fixedly connected to the CNC machining center 1, all of which are convex to ensure stable placement. An auxiliary connecting plate is fixedly connected inside the CNC machining center 1, and a machining device 2 is fixedly connected to the auxiliary connecting plate for easy tool replacement. A feeding table 3 is fixedly connected to the outer wall of the CNC machining center 1 through multiple disassembly and assembly components. The disassembly and assembly components include a working slot on the feeding table 3, and a disassembly and assembly block 14 installed in the working slot. The disassembly and assembly block 14 is L-shaped and cooperates with the working slot. The other end of the disassembly and assembly block 14 cooperates with the CNC machining center 1. Multiple disassembly and assembly bolts 15 are also installed on the disassembly and assembly block 14, allowing operators to quickly disassemble and install parts, greatly facilitating regular maintenance of components.

[0024] A high-precision feeding assembly includes a working cavity within a feeding table 3. A working screw 4 is rotatably connected within the working cavity. The two sides of the working screw 4 have opposite thread directions. Two working sliders 5 are threaded onto the working screw 4 and are symmetrically installed. Each working slider 5 cooperates with one end of the working screw 4, so that when the working screw 4 rotates, it drives the two working sliders 5 to move along both ends of the working screw 4. The ends of both working sliders 5 furthest from the working screw 4 slide through the working cavity. The feeding table 3 has... There are two working slides, and two working sliders 5 are slidably connected to the two working slides respectively, so as to ensure that the working sliders 5 can slide normally. Positioning clamps 6 are fixedly connected to both working sliders 5, and guide grooves 7 are opened on both positioning clamps 6. After the positioning clamps 6 hold the two ends of the workpiece to be processed, they limit it, so that the workpiece to be processed is in the accurate feeding position and in the unclamped sliding state. Under the action of external force, it can slide along the guide grooves 7 into the CNC machining center machine 1 to achieve precise feeding.

[0025] A feeding telescopic motor 8 is fixedly connected to the feeding worktable 3. A pusher plate 9 is fixedly connected to the output end of the feeding telescopic motor 8, which can push the workpiece to be processed into the CNC machining center 1 for processing. The pusher plate 9 is coated with a protective coating that adheres to the outer wall of the pusher plate 9 to prevent damage to the workpiece. A transmission assembly is also installed inside the working cavity. The transmission assembly includes a support plate fixedly connected to the inner wall of the working cavity. A working motor 10 is fixedly connected to the support plate. The feeding worktable 3 is equipped with multiple working buttons, which are all in conjunction with the working motor 10. The operator can operate the working button to control the start, stop, forward and reverse rotation of the working motor 10. A bevel gear 11 is fixedly connected to the output end of the working motor 10, and a bevel gear 2 12 is fixedly connected to the end of the working screw 4 near the working motor 10. The bevel gear 11 and bevel gear 2 12 are meshed with each other, so that when the working motor 10 starts, it can drive the working screw 4 to rotate through the gear meshing transmission. A limit slide rod 13 is also fixedly connected to the inner side wall of the working cavity. The limit slide rod 13 slides through the two working sliders 5, thereby limiting the working sliders 5 so that they can only slide along the direction of the working screw 4.

[0026] In the process of using this utility model, the operator first places the rectangular plate to be processed on the feeding worktable 3, and then starts the working motor 10, so that the bevel gear 11 fixedly connected to the working motor 10 starts to rotate. Due to the meshing characteristics of the gears, the bevel gear 12 will also start to rotate, thereby driving the working screw 4 to rotate. Due to the characteristics of the threaded connection, and the opposite directions of the threads on both sides of the working screw 4, the two working sliders 5 threadedly connected to the working screw 4 will slide along both ends of the working screw 4 under the limiting action of the limiting slider 13, thereby driving the positioning clamps 6 fixedly connected to the working sliders 5 to move together, so that the two positioning clamps 6 abut against the two side walls of the rectangular plate.

[0027] At this time, the rectangular plate is precisely positioned facing the CNC machining center machine 1. Then, the operator starts the feeding telescopic motor 8, which drives the rectangular plate to slide along the guide groove 7 on the positioning clamping plate 6 through the pusher plate 9 into the CNC machining center machine 1 for processing, achieving precise feeding. When the operator needs to perform regular maintenance on the parts, he only needs to remove the disassembly bolts 15 and the disassembly clamping blocks 14 to remove the feeding worktable 3 for maintenance.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
