[0002] With the gradual advancement of production automation, the automotive processing industry, as a cutting-edge sector, is moving towards full-line automation. For products with multiple groove designs based on component structure requirements, existing tooling structures are used, but the grooves are cut one by one, requiring repositioning each time, resulting in cumbersome operation and low processing efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-precision cutting machine with a scientific and reasonable design, simple structure, and stable and reliable operation.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A high-precision cutting machine includes a cutting assembly, a housing, and a tool drive structure. The cutting assembly is installed inside the housing, and the tool drive structure is also installed inside the housing and connected to the cutting assembly.

[0006] The cutting assembly includes a tool structure and a support structure. The support structure is located in the middle of the machine housing and is used to limit and support the workpiece to be cut. The tool structure is guided and moved above the support structure. The tool structure includes blades, a cutter shaft, and a motor. The cutter shaft is horizontally arranged, and multiple blades are evenly spaced and fixed in the middle of the cutter shaft. The blades are all parallel circular structures. One end of the cutter shaft is connected to the motor, and the motor drives the multiple blades to rotate synchronously to perform the cutting work.

[0007] Furthermore, multiple nozzles are fixedly mounted on the upper front end of the support structure, and each nozzle is connected to a coolant delivery device via a conduit.

[0008] Moreover, the support structure includes a base, a limiting frame, a cylinder, and a clamping plate. The base is fixedly installed inside the machine box. A limiting frame is provided at the upper end of the base. The limiting frame is provided with multiple through slots, and the through slots correspond one-to-one with the positions of the blades. The workpiece is clamped between the base and the limiting frame.

[0009] Furthermore, multiple parallel-spaced cylinders are installed in the base below the workpiece. Adjacent cylinders are arranged in opposite directions. Each cylinder's drive rod end is fixed with a clamping plate. When the cylinder tightens, the clamping plate clamps the workpiece from both longitudinal sides to prevent the workpiece from moving when being cut by the blade.

[0010] Furthermore, the tool drive structure specifically comprises horizontally longitudinally arranged tool rails symmetrically installed in the middle of the two transverse sides inside the chassis, and guide rods arranged parallel to each other on the outer side of the tool rails, with the tool rails and guide rods slidably connected to the tool structure.

[0011] Furthermore, each end of the cutter shaft is connected to a slider via a bearing. The slider is slidably connected to the cutter drive structure, and can move back and forth along the cutter path to drive the cutter shaft to move.

[0012] Furthermore, the top plate of the chassis is provided with a horizontally extending track along the upper edge of the front end, and the track is slidably connected to the upper track groove of the chassis door; the bottom plate of the chassis is provided with a track along the upper edge of the front end, and the track is slidably connected to the lower track groove of the chassis door; a drive rod is also connected to the upper end of the chassis door, and the other end of the drive cylinder is fixedly connected to the chassis. The drive cylinder is arranged parallel to the track, and the drive cylinders corresponding to the two sides of the chassis door drive in opposite directions, driving the chassis door to move laterally to both sides respectively.

[0013] Furthermore, the front of the chassis is equipped with double-sided doors that can be opened and closed, and sealing strips are installed on the sides where the doors meet to seal the seams between the two doors.

[0014] The advantages and positive effects of this utility model are:

[0015] This utility model has a simple structure and operation, and can quickly and accurately complete the cutting of multiple wire grooves required for accessories. It has high cutting precision and accurate and reliable positioning. Attached Figure Description
