Abstract
The utility model provides a kind of novel valve stem peripheral milling equipment, comprise lathe, lathe has the lathe middle carriage that the scroll chuck on lathe spindle, the thimble on tail stock, lathe saddle and lathe saddle are arranged, it is characterized in that: lathe middle carriage is fixed with an extruding scroll chuck, the center of extruding scroll chuck is high high consistent with lathe spindle center, three claws of extruding scroll chuck are along pawl, the head of three claws is circular, and the head of three claws installs three deep groove ball bearings respectively.The utility model carries out fineness processing by extrusion principle to valve rod polished rod surface, and can improve the surface smoothness after the processing of valve rod polished rod position, and the processing avoiding manual operation to bring is dangerous, the utility model can obtain old Lathe Modification, and cost is low.
Description
Technical field
The utility model belongs to a kind of valve processing equipment, particularly relates to a kind of equipment processed the valve rod polished rod position of valve.
Background technology
In existing valvular valve rod process engineering, the surface smoothness requirements at valve rod polished rod position is higher, and requirement on machining accuracy reaches 1.6 or 0.8.General is all utilize lathe process, and sand for surface cloth sanding and polishing improves stem surface fineness.
Because valve rod is lathe process, valve rod polished rod surface recycling emery cloth carries out surface finish polishing, but this processing mode cannot reach the designing requirement of more high-precision surface smoothness.Run in opening-closing process at valve, just very easily cause filler place to reveal, make medium formation run, emit, leak, drip.When carrying out sanding and polishing with emery cloth to valve rod, degree of danger is also high, very easily causes industrial accident.
Utility model content
The utility model provides a kind of novel valve stem peripheral milling equipment, its objective is the shortcoming solving prior art and exist, and improve the surface smoothness after the processing of valve rod polished rod position, and it is dangerous to reduce processing, reduces costs.
The utility model solves the technical scheme that its technical problem adopts:
A kind of novel valve stem peripheral milling equipment, comprise lathe, lathe has the lathe middle carriage that the scroll chuck on lathe spindle, the thimble on tail stock, lathe saddle and lathe saddle are arranged, it is characterized in that: lathe middle carriage is fixed with an extruding scroll chuck, the center of extruding scroll chuck is high high consistent with lathe spindle center, three claws of extruding scroll chuck are along pawl, the head of three claws is processed as circle, and the head of three claws installs three deep groove ball bearings respectively.
On lathe middle carriage, spiral shell is provided with angle-iron frame, and extruding scroll chuck is fixedly mounted on angle-iron frame.
Usefulness of the present utility model is:
The utility model carries out fineness processing by extrusion principle to valve rod polished rod surface, and can improve the surface smoothness after the processing of valve rod polished rod position, and the processing avoiding manual operation to bring is dangerous, the utility model can obtain old Lathe Modification, and cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model part-structure figure;
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Detailed description of the invention
As shown in Figure 1, the present invention utilizes extrusion principle, improves valve rod polished rod surface smoothness.Existing used car bed is suitably improved, this lathe have the scroll chuck on lathe spindle, the movable thimble on tail stock, lathe saddle 1, lathe saddle 1 are arranged lathe middle carriage 2, lathe middle carriage 2 has lathe upper slide rest, lathe upper slide rest is arranged on lathe upper slide rest positioning bolt hole, upper slide rest has cutter platform.First the cutter platform on lathe middle carriage 2 and upper slide rest are disassembled.With Plate Welding angle-iron frame 3, below angle-iron frame 3 with lathe upper slide rest positioning bolt hole for key well, with bolt, angle-iron frame 3 is fixed on lathe middle carriage 2, an extruding scroll chuck 4 is installed in angle-iron frame 2 side, and the chuck hub of extruding scroll chuck 4 is high high with lathe spindle center consistent after angle-iron frame 3 installs.Three claws 5 on extruding scroll chuck 4 adopt along pawl, and the head of three claws 5 is processed as circle, install the deep groove ball bearing 6 of three same models respectively.
When extrusion process is carried out to valve rod polished rod 7, valve rod head (being also valve rod and flashboard junction) is clamped with the scroll chuck on lathe spindle, tail stock movable thimble withstands valve rod screw mandrel head, the gap of the centre of the deep groove ball bearing 6 of three same models that the polished rod 7 of valve rod is installed from the extruding scroll chuck 4 angle-iron frame 3 is through (center line of scroll chuck 4 is consistent with lathe spindle center line, angle-iron frame 3 is locked on lathe middle carriage 2), three deep groove ball bearings 6 of extruding scroll chuck 4 are utilized to clamp one end (any of valve rod polished rod 7) of valve rod polished rod 7, start lathe, lathe saddle 1 adopts autofeed pattern, saddle 1 is advanced, middle carriage 2 is advanced, extruding scroll chuck 4 is advanced, three deep groove ball bearings 6 are advanced along valve rod polished rod 7 and extrude valve rod polished rod 7 position, valve rod polished rod 7 surface smoothness is made to reach designing requirement.
