The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1, shown in 2, a kind of changement that is used on the load-sensitive proportional multi-path valve is press-fitted uses frock, comprises base 6 and handle set 3; Described handle set 3 is fixed on the left side of said base 6 through first screw 1, is provided with first connecting rod 9 and second connecting rod 10 in the said handle set 3, wherein; Install successively from bottom to up on the described base 6 and decide direction pin 11 and depthkeeping degree pin 12, the described right-hand member of deciding direction pin 11 has been attacked external screw thread, and is connected on the base 6 through external screw thread; The right-hand member 16 of described depthkeeping degree pin 12 is with spring 5; And be fixed in the locational screw hole of round bottom plate 8 axial lines, described round bottom plate 8 is fixed on the base 6 through second screw 7, on the stage casing 15 of described depthkeeping degree pin 12 elongate slots is arranged; The 3rd screw 4 on the said base 6 inserts and withstands described elongate slots; The left end 14 of said depthkeeping degree pin 12 has one 2, and described axle 2 levels are installed on the handle set 3, and perpendicular to depthkeeping degree pin 12; Axle 2 is provided with radial hole; Be with the left end 14 and first connecting rod 9 of depthkeeping degree pin 12 in the described radial hole, described first connecting rod 9 is installed in the U-lag of second connecting rod 10 upper ends, and the inverted U-channel of described second connecting rod 10 lower ends blocks the described left end of deciding direction pin 11.
Described depthkeeping degree pin 12 is the step axle; Adopt modified steel manufacturing, quenching and tempering hardness is HRC25~30, is quenched to HRC30~35; The stage casing matched in clearance of 15 cylindricals in dowel hole of said depthkeeping degree pin 12 is 0.01~0.03mm; Concentricity is not more than 0.02mm, and left end 14 cylindricals matched in clearance in the radial hole on axle is 0.01~0.03mm, and described depthkeeping degree pin surfaces blackout is handled.
Describedly decide direction pin 11 and be the step axle, adopt modified steel manufacturing, quenching and tempering hardness is HRC25~30, saidly decide the processing of direction pin surfaces blackout.
Described base 6 adopts modified steel manufacturing, and quenching and tempering hardness is HRC25~30, and is installed on the flat-nose pliers of pressure workbench, and said susceptor surface blackout is handled.
Described first connecting rod 9 is press-fitted the degree of depth according to the locational screw adjusted of said round bottom plate 8 axial lines in the radial hole of axle 2.
Described first screw 1, second screw 7 and the 3rd screw 4 are hexagon socket cap head screw.
Described second connecting rod 10 is vertical with described 2.
Like Fig. 1, shown in 2, during installation, at first let radial hole on left end 14 aiming axis 2 of depthkeeping degree pin 12, depthkeeping degree pin can rely on spring force to withstand on all the time in the radial direction through hole on the described axle 2, rotates to prevent axle 2; Then the sub-assembly of first connecting rod in the changement 9 and second connecting rod 10 is loaded onto, blocked the said left end cylindrical of deciding direction pin 11 with the inverted U-shaped notch of described second connecting rod 10, the right-hand member of first connecting rod 9 is the radial hole on the aiming axis 2 then; At last be pressed into the radial hole on the axle to the right-hand member of first connecting rod 9 by forcing press, and the described depthkeeping degree of roof pressure pin 12 is toward moving down, the compression spring props up base 6 surfaces and accomplishes and be press-fitted operation until the largest end face 17 of described depthkeeping degree pin 11.
Frock is not used or is press-fitted and accomplishes the back when frock is taken off changement, owing to stopping of the 3rd screw arranged, can prevent that depthkeeping degree pin from deviating from the tool locating pin-and-hole.
Consult Fig. 9,10, be the assembly----changement structure diagram that the present invention need be press-fitted, the first connecting rod 9 among the figure on the connection rod set component need be pressed in the radial direction through hole of axle 2 on handle set 3 sub-assemblies, promptly is assembled into changement.If it is dark or shallow excessively that first connecting rod 9 was press-fitted in axle 2 radial direction through hole, or second connecting rod 10 and axle 2 out of plumb, the follow-up assembling that makes banked direction control valves can't be carried out.
