Description

Flange mounting hole tool back plane machining tools

Technical field

The utility model is related to a kind of machining tools.The utility model is suitable for valve, water pump connecting flange is installed Hole back side cutting tool.

Background technology

Flanged joint is the main connection type that the equipment such as valve, water pump are connected with each other with medium delivery pipe road, in valve When being connect with pipe flange, passes through flange hole to coordinate with nut using bolt and fix the flange on the flange and pipeline on valve body Sealing installation, valve flange and pipe flange contact with each other face can by machine tooling, in order to bolt and nut can reliably by Valve flange is closely connect with mounting flange, it is desirable that the flange hole back side have with the mutually matched burnishing surface in bolt and nut end face, The especially processing at the valve flange hole back side, since position limits, machine tool puts in processing, currently, to valve flange hole The processing of back side plane all uses drilling machine that shaft is inserted into the valve flange hole back side, and cutter is inserted into shaft by operating personnel In radial hole, drilling machine drives shaft and cutter rotation, and cutter is made to realize the machining to valve flange hole back side plane, processing Behind a complete hole, pulling-out of cutter is exited shaft and reinserts another valve flange out of shaft radial hole by operating personnel Hole, then cutter is inserted into shaft radial hole to the machining for carrying out second valve flange hole by operating personnel, operation is non- Often trouble, and processing efficiency is very low.When especially to the valve flange hole machined of large-diameter butterfly valve, operating personnel need up and down It runs and loads and unloads cutter, work is tired, efficiency is low.

Invention content

The purpose of this utility model is to be directed to disadvantage of the existing technology, provides a kind of simple to operate, processing effect The high flange mounting hole tool back plane machining tools of rate.

The technical solution of the utility model includes shaft；Mainly axial window is formed on the cylinder of shaft lower part side Mouthful, automatic telescopic cutter mechanism is installed in the axial direction window；The automatic telescopic cutter mechanism is by rotary shaft, knife rest and set of blades At；Rotating shaft terminal is mounted in the upper and lower ends face of axial window, and the center line of rotary shaft is located at the right side of shaft centerline, The two center line is mutually parallel, and knife rest side is installed on the rotary shaft, and blade is inlaid in knife rest left plane, outside the right plane of knife rest Side has the cylindrical surface of curved surface identical as shaft external cylindrical surface, has between the right planar inner of knife rest and axial window right side mutual Retention device, the blade upper end knife edge is coordinated to protrude plane on knife rest；When knife rest is rotated in place to the left with respect to shaft, knife rest is whole In embedded axial direction window, when knife rest is rotated in place to the right with respect to shaft, the blade upper end knife edge is on the outside of shaft cylindrical surface.

In above technical scheme, blade uses triangular structure, and the bayonet in knife rest left side plane is mutual with blade The triangle bayonet of cooperation.

In above technical scheme, the triangle bayonet inferior horn of knife rest is connected to a circular-shaped, concave cavity, described in blade inferior horn is inserted into In circular-shaped, concave cavity.

In above technical scheme, when knife rest is rotated in place to the right with respect to shaft, the blade upper end knife edge is located at shaft radial direction On direction.

The utility model has the advantages that using the cutter mechanism with automatic telescopic function, drilling machine or numerically-controlled machine tool band turn When axial right rotation, knife rest is retracted the axial window interior of shaft together with blade under the action of the centrifugal force, and shaft is inserted into flange hole Interior to take knife rest and blade to the flange hole back side, then, shaft is stretched out to anticlockwise, knife rest together with blade under the action of the centrifugal force Shaft external cylindrical surface, the blade upper end knife edge carry out machining to the flange hole back side, after processing is completed by shaft to right rotation, knife Frame is retracted the axial window interior of shaft together with blade again, and shaft is exited the next flange hole back side of processing from flange hole, In whole process, operating personnel do not have to handling cutter, easy to operate, laborsaving, high in machining efficiency.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

Flange mounting hole tool back plane machining tools as shown in Figure 1, including shaft 1,1 upper end of shaft can be clamped in brill On bed or numerically-controlled machine tool collet, left or right direction is driven to rotate by drilling machine or main shaft of numerical control machine tool；In 1 lower part side cylinder of shaft It is formed with axial window 2 on body, automatic telescopic cutter mechanism is installed in the axial direction window 2；The automatic telescopic cutter mechanism is by revolving Shaft 3, knife rest 6 and blade 5 form；3 both ends of rotary shaft are mounted in the upper and lower ends face of axial window 2, the center of rotary shaft 3 Line is located at the right side of 1 center line of shaft, and the two center line is mutually parallel, and 6 side of knife rest is mounted in rotary shaft 3, and blade 5 is embedded in In 6 left side plane of knife rest, blade 5 uses wolfram steel piece, is inlaid in the bayonet of 6 left side plane of knife rest, wolfram steel piece center is by interior Hex screw 4 is fixedly mounted with knife rest 6, and 6 right planar outboard of knife rest has the cylindrical surface of curved surface identical as 1 external cylindrical surface of shaft, There is mutual cooperation retention device between 2 right side of 6 right planar inner of knife rest and axial window, the retention device force knife rest 6 with For shaft 1 jointly to anticlockwise, the 5 upper end knife edge of blade protrudes plane on knife rest 6；It is rotated in place to the left with respect to shaft 1 in knife rest 6 When, in the whole embedded axial window of knife rest 62, when knife rest 6 is rotated in place to the right with respect to shaft 1, the 5 upper end knife edge of blade, which is in, to be turned On the outside of 1 cylindrical surface of axis, make shaft 1 to when anticlockwise, blade 5 cuts the flange hole back side, the external cylindrical surface and method of shaft 1 Flange aperture inner wall activity coordinates, and ensures the flexible rotating in flange hole of shaft 1.When starting processing, shaft 1 is driven by drilling machine first To right rotation, knife rest 6 to be hidden into inside axial window 2, shaft 1 passes through flange hole, and knife rest 6 is made to be located at the flange hole back side, then, Shaft 1 throws away axial window 2 to anticlockwise, by knife rest 6, and under the action of retention device, blade 5 cuts the flange hole back side Cut processing；After the completion of machining, shaft 1 hides knife rest 6 into inside axial window 2 to right rotation again, from the flange hole back side It exits, prepares to process next flange hole back side.The centrifugal force that blade 5 generates when being rotated by shaft 1 automatically controls, operation side Just, laborsaving, it is high in machining efficiency.Shaft 1 can also be fixedly installed in axial window 2, at this point, being used between knife rest 6 and shaft 1 Flexible connection, allows knife rest 6 to be rotated in shaft 1.

Blade 5 uses triangular structure, and the bayonet in 6 left side plane of knife rest is and 5 mutually matched triangle card of blade Mouthful.

The triangle bayonet inferior horn of knife rest 6 is connected to a circular-shaped, concave cavity 7, and 5 inferior horn of blade is inserted into the circular-shaped, concave cavity 7, makes Two sides of 5 triangle of blade are in close contact with two sides of 6 triangle bayonet of knife rest.

When knife rest 6 is rotated in place to the right with respect to shaft 1, the 5 upper end knife edge of blade is located at shaft 1 radially.
