Description

Technical Field

[0001] The utility model relates to a numerical control milling machine for processing valve stems to prevent workpiece offset, belonging to the field of milling machines for processing valve stems. Background Technique

[0002] The valve stem is an important component of the valve and is used for transmission. It is connected to the actuator or handle at the upper part and directly drives the valve core to move or rotate at the lower part. When the valve stem is installed according to the equipment, it can be processed by a milling machine, which is a machine tool for processing the surface of the workpiece with a milling cutter to process the size of the valve stem.

[0003] In the prior art, when the valve stem processing milling machine performs rotary processing, it is necessary to position and fix the internal valve stem. Due to the different sizes of the valve stems, when the internal arc-shaped clamping plates clamp smaller or larger valve stems, the force fixation on the surface of the valve stem is not firm enough, which affects the offset of the milling cutter during the processing of the valve stem. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a numerical control milling machine for processing valve stems to prevent workpiece offset, so as to solve the problems put forward in the above background technique.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical scheme: a numerical control milling machine for processing valve stems to prevent workpiece offset, including a processing machine tool. An adjusting plate is arranged inside the processing machine tool. A clamping mechanism is arranged above the adjusting plate. The clamping mechanism includes a protruding plate. A cross-shaped fixing piece penetrates through the inside of the protruding plate. One end of the cross-shaped fixing piece is movably connected to a clamping and engaging plate.

[0006] On the reverse side of the clamping and engaging plate, there is a fixed clamping plate fixedly connected above the adjusting plate. A sliding groove is opened above the clamping and engaging plate. One side of the clamping and engaging plate is fixedly connected to a right-angle plate. An electric push rod is fixedly connected to the outer wall of the right-angle plate. One end of the electric push rod is fixedly connected to a transverse clamping plate.

[0007] Preferably, the cross-shaped fixing piece is threaded through the inside of the protruding plate and connected to the clamping and engaging plate. An arc-shaped groove is opened on the outer wall of the clamping and engaging plate.

[0008] Preferably, a cross clamping is formed between the clamping and engaging plate, the fixed clamping plate and the transverse clamping plate. A telescopic structure is formed between the electric push rod and the transverse clamping plate.

[0009] Preferably, long grooves are opened inside the upper part of the adjusting plate. The number of the long grooves is four, and they are evenly distributed at the front and rear ends above the adjusting plate.

[0010] Preferably, an operation panel is closely attached to the front of the processing machine tool. A protective wire board is movably clamped above the operation panel, and the operation panel is connected to the processing machine tool by screws.

[0011] Preferably, a square groove is provided below the operation panel and is opened on the front of the processing machine tool. One side of the processing machine tool is fixedly connected with a ventilation board.

[0012] Preferably, support feet are fixedly connected to the lower part of the processing machine tool. One side of the operation panel is provided with a front cover plate that is movably connected to the front of the processing machine tool.

[0013] Preferably, the support feet are respectively arranged around the lower part of the processing machine tool, and the front cover plate is snap-fitted and fixed to the front of the processing machine tool.

[0014] Advantages of the present utility model:

[0015] Compared with the prior art, the CNC milling machine for valve stem processing that prevents workpiece offset is internally connected through a clamping mechanism. When clamping and fixing the internal valve stem, the electric push rod inside can be operated to clamp and fix the central valve stem with the connected horizontal clamping plate, so that the clamping plate forms a cross-directional force clamping and fixing on the valve stem. When the milling machine rotates and processes the valve stem, it can perform more precise processing and avoid the offset generated during rotation processing.

[0016] Compared with the prior art, the CNC milling machine for valve stem processing that prevents workpiece offset clamps and fixes the valve stem through a clamping mechanism.
