Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that if related in the utility model embodiment directionality instruction (such as upper and lower, left and right, it is preceding,
Afterwards ...), then directionality instruction is only used for explaining opposite between each component under a certain particular pose (as shown in the picture)
Positional relationship, motion conditions etc., if the particular pose changes, directionality instruction is also correspondingly changed correspondingly.
In addition, if relating to the description of " first ", " second " etc. in the utility model embodiment, " first ", " the
Two " etc. description is used for description purposes only, and is not understood to indicate or imply its relative importance or is implicitly indicated meaning
The quantity of the technical characteristic shown." first " is defined as a result, the feature of " second " can explicitly or implicitly include at least one
A this feature.It in addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Based on personnel can be realized, this technical side will be understood that when the combination of technical solution appearance is conflicting or cannot achieve
The combination of case is not present, also not within the protection scope of the requires of the utility model.
The utility model provides a kind of hole drilling positioning fixture for valve body.
In the present embodiment, referring to Figures 1 and 2, the hole drilling positioning fixture for being used for valve body include bottom plate 1, supporting table 2,
Cabinet 4, cylinder block 5 and cylinder 6 with installation cavity 3, the supporting table 2 are arranged on the bottom plate 1 in installation cavity 3, the case
4 front end of body has opening, and the upper side wall of cabinet 4 is equipped with the axis hole 7 protruded into for drill bit, passes through sliding rail in the installation cavity 3
Slide block assembly 8 is provided with left clamp 9 and right clamping plate 10, is provided with contraction spring between the left clamp 9 and the left side wall of cabinet 4
11 and eccentric stiffener, the eccentric stiffener is for driving left clamp 9 to horizontally slip on sliding-rail sliding component 8, the cylinder 6
It is fixed on cylinder block 5, push rod 12 is fixed on the output shaft of cylinder, is connected at the top of the push rod with right clamping plate.Eccentric stiffener
Be able to drive left clamp and carry out left and right fine tuning, when valve body outer dimension changes lesser can by the adjusting of left clamp come
It is directed at bore position, without re-replacing fixture, improves production efficiency, the scope of application is wider.Wherein contraction spring is for a left side
The return of clamping plate.
In the present invention, the bottom plate is equipped with mounting hole 13；5 two sides of cylinder block have outstanding
Rank 14, the step 14 are equipped with screw hole 15, and cylinder block 5 is bolted on bottom plate；The left clamp 9 and right clamping plate
