Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically to a guide and clamping structure. Background Technology

[0002] A milling and drilling machine is a specialized machine tool used for the efficient machining of shaft parts. It is mainly used for milling end faces, drilling center holes, drilling, tapping, and other processes, and is suitable for industries such as automotive, machinery manufacturing, and rail transportation. Milling and drilling machines can be classified into manual milling machines and automatic milling machines according to their structure. Automatic milling machines are further divided into CNC milling machines and general-purpose milling machines. CNC milling machines achieve complex machining through computer program control, while general-purpose milling machines offer more flexible operation.

[0003] Traditional milling and drilling machines have difficulty accurately drilling holes at the center of the object to be assembled when drilling holes on the end face of the object. They also have difficulty maintaining the coaxiality of the center holes when aligning the center holes of two sets of objects to be assembled. Utility Model Content

[0009] Using the above technical solution, the fixed positioning tapered ring is used to place and limit the items to be assembled. The fixed positioning tapered ring in the first fixed seat is used to place and limit one group of items to be assembled, and the fixed positioning tapered ring in the second fixed seat is used to place and limit another group of items to be assembled. The linear guide post and sleeve are used for limiting.

[0010] A further improvement of this utility model is that the guide rod locking fixing seat is located outside the second fixing seat, and the guide rod locking fixing seat is also located outside the first fixing seat.

[0012] A further improvement of this utility model is that the inner side of the piston rod of the oil cylinder is on the same horizontal plane as the inner side of the rotary hydraulic cylinder.

[0013] Using the above technical solution, the sliding positioning seat can be moved horizontally along the guide rod body by extending and retracting the piston rod of the hydraulic cylinder.

[0014] A further improvement of this utility model is that: the guide rod body is located on both sides of the cylinder piston rod body, the cylinder piston rod is located on both sides of the fixed positioning tapered ring, and the sliding positioning seat passes through the outer surface of the guide rod body.

[0015] By adopting the above technical solution, the sliding positioning seat is limited by the guide rod body to prevent the position of the sliding positioning seat from shifting.

[0016] A further improvement of the present invention is that the guide and clamping assembly includes a rotor hub body fixedly connected to the inner end of the fixed positioning tapered ring in the first fixed seat. A tapered sleeve is fixedly connected to the inner wall of the rotor hub body. An auxiliary component is fixedly provided at the inner center of the tapered sleeve. A center drill is connected to the inner end of the auxiliary component. A tool holder is fixedly connected to the upper side of the inner wall of the tapered sleeve. Triangular blades are provided on both sides of the outer wall of the auxiliary component.

[0017] A further improvement of this utility model is that the tool holder is located above the center drill, and the triangular blades are located on both sides of the center drill.
