Abstract

The invention provides novel valve rod cylindrical grinding equipment. The novel valve rod cylindrical grinding equipment comprises a lathe. The lathe is provided with a three-jaw chuck, an ejector pin, a large lathe carriage and a medium lathe carriage which is arranged on the large lathe carriage. The three-jaw chuck is arranged on a lathe spindle. The ejector pin is arranged on a tail seat of the lathe. The novel valve rod cylindrical grinding equipment is characterized in that an extrusion three-jaw chuck is fixed to the medium lathe carriage; the center height of the extrusion three-jaw chuck is identical to that of the lathe spindle; three clamping jaws of the extrusion three-jaw chuck are smooth jaws; the heads of the three clamping jaws are round; three deep groove ball bearings are installed on the heads of the three clamping jaws correspondingly. The invention further provides a valve rod cylindrical grinding method. According to the novel valve rod cylindrical grinding equipment and the valve rod cylindrical grinding method, through an extrusion principle, smoothness machining is conducted on the surface of a polish rod of a valve rod, the surface smoothness of the polish rod position of the valve rod after machining can be improved, and machining danger caused by manual operation is avoided. Through the novel valve rod cylindrical grinding equipment and the valve rod cylindrical grinding method, an old lathe can be modified, and the cost is low.

Description

A kind of novel valve stem peripheral milling equipment and valve rod peripheral milling method
Technical field
The invention belongs to a kind of valve processing equipment, particularly relate to a kind of Apparatus and method for that the valve rod polished rod of valve is processed。
Background technology
In now 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。Being typically all and utilize lathe process, sand for surface cloth sanding and polishing improves stem surface fineness。
Owing to valve rod is lathe process, valve rod polished rod surface recycling emery cloth carries out surface finish polishing, but this processing mode is unable to reach the designing requirement of the high-precision surface smoothness of comparison。Run in opening-closing process at valve, just very easily cause filler place to reveal, make medium formation run, emit, leak, drip。When valve rod being carried out sanding and polishing with emery cloth, degree of danger is also high, very easily causes industrial accident。
Summary of the invention
The present invention provides a kind of novel valve stem peripheral milling equipment, its objective is to solve the shortcoming that prior art exists, and improves the surface smoothness after the processing of valve rod polished rod position, and reduces processing danger, reduces cost。
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel valve stem peripheral milling equipment, including lathe, lathe has the lathe middle carriage arranged on the scroll chuck on lathe spindle, the thimble on tail stock, lathe saddle and lathe saddle, it is characterized in that: lathe middle carriage is fixed with an extruding scroll chuck, the center of extruding scroll chuck is high high with lathe spindle center consistent, three claws of extruding scroll chuck are that the head of three claws is processed as circle, and the head of three claws is respectively mounted three deep groove ball bearings along pawl。
On lathe middle carriage, spiral shell is provided with angle-iron frame, and extruding scroll chuck is fixedly mounted on angle-iron frame。
A kind of method of valve rod peripheral milling, it is characterized in that: by valve rod two ends by the thimble clamping of the scroll chuck on lathe spindle and tail stock, valve rod polished rod passes the gap of the centre of three deep groove ball bearings on the extruding scroll chuck being installed on lathe middle carriage and clamps, start lathe, lathe saddle adopts autofeed pattern, saddle is advanced, saddle drives middle carriage to advance, middle carriage drives extruding scroll chuck to advance, and three deep groove ball bearings are advanced along valve rod polished rod and valve rod polished rod position is extruded。
The invention have benefit that:
Valve rod polished rod surface is carried out fineness processing by extrusion principle by the present invention, it is possible to improving the surface smoothness after the processing of valve rod polished rod position, and avoid the processing that manual operation brings dangerous, old Lathe Modification can be obtained by the present invention, and cost is low。
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described。
Fig. 1 is part-structure figure of the present invention;
Fig. 2 is that the A of Fig. 1 is to schematic diagram。
Detailed description of the invention
As it is shown in figure 1, the present invention utilizes extrusion principle, improve valve rod polished rod surface smoothness。Existing used car bed is suitably modified, this lathe has on the scroll chuck on lathe spindle, the movable thimble on tail stock, lathe saddle 1, lathe saddle 1 and has lathe upper slide rest on the lathe middle carriage 2 of setting, lathe middle carriage 2, lathe upper slide rest is arranged on lathe upper slide rest positioning bolt hole, and upper slide rest has cutter platform。First the cutter platform on lathe middle carriage 2 and upper slide rest are disassembled。With one angle-iron frame 3 of Plate Welding, with lathe upper slide rest positioning bolt hole for key well below angle-iron frame 3, 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, the head of three claws 5 is processed as circle, is respectively mounted the deep groove ball bearing 6 of three same models。
When valve rod polished rod 7 is carried out extrusion process, valve rod head (namely 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 (centrage of scroll chuck 4 is consistent with lathe spindle centrage, angle-iron frame 3 is locked on lathe middle carriage 2), three deep groove ball bearings 6 utilizing extruding scroll chuck 4 clamp one end (any one head 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 valve rod polished rod 7 position are extruded, valve rod polished rod 7 surface smoothness is made to reach designing requirement。
