Description
Technical field
The utility model is related to a kind of piston rod and draws hole tool.
Background technology
Current piston rod is on periphery or end face perforate, and the required precision in hole is tighter, and directly drill centering difficulty,
And it is less efficient, it is difficult to ensure quality.
It is generally to fix to aid in by other fixtures, without specific purpose tool, so when hole is drawn, precision reaches in operation
Less than, or even easily brill is inclined in hole, does not reach predetermined effect, causes piston rod to scrap, production cost is high, the process-cycle is long, and
It cannot be guaranteed that the product quality of piston rod.
Utility model content
The utility model provides a kind of piston rod and draws hole tool, realizes that to draw hole centering accurate, conveniently, and efficiency compared with
High, quality is preferable.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：A kind of piston rod draws hole tool, bag
Include that end face draws aperture apparatus and cylinder draws aperture apparatus, end face draws aperture apparatus and draws hole fixed cover including end face, and end face draws in the fixed cover of hole
Stepped hole provided with docking, the diameter of the inboard aperture of stepped hole is suitable with diameter of piston rod, and the apertura lateralis of stepped hole is fixed for end face
Position hole；Cylinder, which draws aperture apparatus, includes the upper and lower deck by screw fixation, is respectively equipped with the horizontal direction on upper and lower deck pair
The upper and lower groove that should coordinate, upper and lower groove forms piston rod and accommodates cavity after coordinating, upper blocking seat middle part is vertically provided with
Cylinder positioning hole, cylinder positioning hole is connected with upper groove.
Upper and lower groove is semi-circular recesses, and the cylindrical cavity being adapted with piston rod is formed after correspondence split.
Lower deck upper surface is provided with square guide pillar, and corresponding upper blocking seat lower surface is provided with square guide pillar hole.
Cylinder positioning hole forms for up big and down small upper and lower stepped hole docking.
Lock-screw is provided with the side wall in top bar hole in the horizontal direction.
Provided with four square guide pillars at corner on lower deck upper surface, corresponding upper blocking seat lower surface is provided with four sides
The guide pillar hole of shape.
Screw is provided with upper and lower deck corner and sets screw to fasten.
Relative to prior art, the utility model is when drawing hole, it is ensured that the perpendicularity in hole so that be unlikely to bore inclined,
The quality of piston rod product is ensure that, percent defective is reduced, while reducing production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A-A sectional views.
Embodiment
Embodiment：As shown in Figure 1, 2, a kind of piston rod draws hole tool, including end face draws aperture apparatus 3 and cylinder draws aperture apparatus
2, end face draws aperture apparatus 3 and draws hole fixed cover including end face, and end face draws the stepped hole provided with docking in the fixed cover of hole, stepped hole it is interior
The diameter of side opening is suitable with the diameter of piston rod 1, and the apertura lateralis of stepped hole is end face positioning hole；Cylinder draws aperture apparatus 2 and includes passing through
The upper and lower groove of corresponding matching is respectively equipped with lower deck 7, the upper blocking seat 6 of screw fixation, upper and lower deck in the horizontal direction,
Upper and lower groove forms piston rod and accommodates cavity after coordinating, the middle part of upper blocking seat 7 is vertically provided with cylinder positioning hole 9, and cylinder is fixed
Position hole 9 is connected with upper groove.
Upper and lower groove is semi-circular recesses, and the cylindrical cavity being adapted with piston rod is formed after correspondence split.
The lower upper surface of deck 7 is provided with square guide pillar 5, and the corresponding lower surface of upper blocking seat 6 is provided with square guide pillar hole.
Cylinder positioning hole 9 forms for up big and down small upper and lower stepped hole docking.
Lock-screw 8 is provided with the side wall in top bar hole in the horizontal direction.
Provided with four square guide pillars 5 at corner on the lower upper surface of deck 7, corresponding upper blocking seat lower surface is provided with four
Square guide pillar hole.
Screw is provided with upper and lower deck corner and sets screw 4 to fasten.
When using, piston rod is placed on upper blocking seat 7, and one end insertion end face draws in the stepped hole of aperture apparatus 3, so
Four square guide pillar hole corresponding matchings of the four square guide pillars 5 descended afterwards on the upper surface of deck 7 and upper blocking seat, by upper blocking seat
After 6 fasten, fixed with screw lock.Then as needed end face or cylinder can be carried out drawing hole operation.
