Abstract

A mechanical grinding device of a return valve sealing face comprises a taper-shank core shaft; the upper end of the taper-shank core shaft is connected with a main shaft of a radial drilling machine; the lower end of the taper-shank core shaft is provided with internal holes which are matched with the upper portion of a connection shaft in a clearance mode; a lower portion seam allowance of the connection shaft is matched with a guide sleeve; the lower end of the taper-shank core shaft is arranged inside the guide sleeve; guiding of the guide sleeve is achieved along with axial movement of the taper-shank core shaft; a compression spring is arranged between the taper-shank core shaft and the connection shaft inside the guide sleeve; the lower portion of the connection shaft is provided with an offcenter hole; an offcenter block which is downwardly connected with a grinding rod is arranged inside the offcenter hole; the top of the grinding rod is connected with the top face of a connection plate; the connection plate is connected with a grinding plate which is arranged under the connection plate through coupling screws; and an axial limitation pin is arranged in the compression spring to control the maximum compression amount of the compression spring. The mechanical grinding device of the return valve sealing face has the advantages of having multiple functions on the basis that the existing functions of the radial drilling machine are not destroyed; being complex in grinding track, reasonable in movement and convenient to use, being capable of replacing grinding tools according to workpiece sizes, improving the efficiency and meanwhile guaranteeing quality stability of grinding.

Description

Return valve sealing surface mechanical lapping equipment
Technical field
The utility model relates to the mechanical lapping technical field.
Background technology
At present, conventional Ginding process is hand lapping, and simple milling tool is used in hand lapping, does not need complicated milling apparatus or mechanism, but takes a lot of work effort, and production efficiency is low, grinds the technical merit that quality depends on the workman.Therefore, grinding quality stablizes inadequately.Adopt mechanical grinding device to grind, the efficient height, stay in grade is no longer dependent on operating personnel's technical capability.But the most grinding track of existing mechanical milling apparatus is simple, and is improper as if selecting for use, can make sealing surface not reach the geometrical precision of regulation, causes low quality; If select the grinder of grinding track complexity for use, can improve the quality and efficient, but acquisition cost will increase greatly.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to propose a kind of return valve sealing surface mechanical lapping equipment, can reduce equipment investment, improve grind quality, have easy for installation, simple in structure, good rigidly, flexible and convenient operation, be suitable for the characteristics of suitability for industrialized production.
For achieving the above object, the utility model is taked following technical scheme:
A kind of return valve sealing surface mechanical lapping equipment, comprise that the upper end is connected in the taper shank mandrel 9 of radial drilling machine main shaft, the lower end of taper shank mandrel 9 is provided with the endoporus that cooperates with the upper gap of connecting axle 6, the bottom seam of connecting axle 6 cooperates with fairlead 7, the lower end of taper shank mandrel 9 is arranged in fairlead 7, and fairlead 7 moves axially along taper shank mandrel 9 and realizes guiding; Between fairlead 7 inner taper shank mandrels 9 and connecting axle 6, be provided with compression spring 8, connecting axle 6 bottoms have eccentric orfice, be provided with eccentric block 5 in the eccentric orfice, eccentric block 5 connects milling bar 4 downwards, milling bar 4 tops connect the end face of terminal pad 2, and terminal pad 2 connects the abrasive disk 1 of below by attachment screw 3.
Be provided with axial limiting pin 10 in the described compression spring 8, with the maximum compressibility of control compression spring 8.
Described milling bar 4 tops are spherical, are positioned at the draw-in groove that terminal pad 2 end faces arrange.
Compared with prior art, the utility model designs mechanical lapping equipment at radial drilling machine, radial drilling machine is increased grind function, and do not destroy original function, a tractor serves several purposes.Reduce equipment investment cost, met or exceeded the effect of mechanical grinding device.Grinding track complexity of the present utility model, motion are rationally, and be easy to use, can change lap tool by the workpiece size, guaranteed to grind the stable of quality when raising the efficiency, and experimental results show that this mechanism integrates economy, practicality.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
A kind of return valve sealing surface of the utility model mechanical lapping equipment, comprise that the upper end is connected in the taper shank mandrel 9 of radial drilling machine main shaft, the lower end of taper shank mandrel 9 is provided with endoporus, the top of connecting axle 6 and the little matched in clearance of this endoporus, the bottom seam of connecting axle 6 cooperates with fairlead 7 and is connected by sunk screw 11.The lower end of taper shank mandrel 9 is arranged in fairlead 7, and the straight section cylindrical of the cover endoporus upper end edge taper shank mandrel 9 of fairlead 7 can move axially realizes guiding; Between fairlead 7 inner taper shank mandrels 9 and connecting axle 6, be provided with compression spring 8, be provided with axial spacer pin 10 in the compression spring 8, with the maximum compressibility of control compression spring 8.Connecting axle 6 bottoms have eccentric orfice, eccentric block 5 is arranged in the eccentric orfice, radially clamp by pinching screw 12, eccentric block 5 connects milling bar 4 downwards, milling bar 4 tops are spherical, be positioned at the draw-in groove that terminal pad 2 end faces arrange, terminal pad 2 bottoms are abrasive disk 1, connect by attachment screw 3 between the two.
The radial drilling machine main shaft drives milling bar 4 motions by taper shank mandrel 9 and connecting axle 6, eccentric block 5 can be regulated offset in circumferential locations by changing its top, spherical position, milling bar 4 tops drives abrasive disk 1 by terminal pad 2 and rotates in a circumferential direction, radially wobble under the effect of eccentric block 5 simultaneously, final abrasive disk 1 is realized the grinding of sealing surface under the drive of radial drilling machine main shaft.
The above only is embodiment of the present utility model, it is to be noted, for a person skilled in the art, can also make a lot of modification and improvement according to invention spirit of the present utility model and principle, as: the change of each parts connected mode, eccentric block is changed into other form, is connected in other lathes etc.But these modification and improvement all belong to the claim that the utility model is applied for.
