Description

Axis hole and milling flat verticality detect frock
Technical field
The present invention relates to a kind of axis hole and milling flat verticality and detect frock, belong to the technical field of tooling device.
Background technology
In the processing of workpiece, assembling process, often need the verticality of two of workpiece structures to measure, determine whether workpiece meets the requirements such as processing, assembling.Existing verticality measuring tool is mainly try square, three-coordinates measuring machine, plumb bob, laser measuring apparatus etc.These instruments are often simple in structure, can be for straight line and planes, and the measurement between plane and plane.But the complex structure of a lot of workpiece, traditional testing apparatus for verticality is not in workpiece, to put position measurement well, be exactly measuring process too complexity or survey instrument are too expensive, traditional simple vertical degree pick-up unit can not be finely applied in workpiece assembling process and go.The measurement mechanism of some verticality, although can carry out squareness measurement to workpiece, measures
Result can not show very intuitively.
Summary of the invention
The problems such as the object of the invention is to provide a kind of axis hole and milling flat verticality to detect frock, has solved testing apparatus for verticality that prior art exists and can not put into workpiece and measure, and squareness measurement process is too complicated, squareness measurement result is not directly perceived.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs:
It comprises base, described base is provided with horizontal plane and the perpendicular intersecting vertically, described horizontal plane and perpendicular intersection are provided with vertical through hole, one spacer vertically arranges and occupy in the middle of described vertical through hole, described spacer and perpendicular are fixed, described spacer is provided with horizontal through hole, the axis of described horizontal through hole and the vertically intersect vertical axis of through hole, position away from vertical through hole on described base is provided with two vertical pin rods, and described vertical pin rod is about described horizontal through hole
Axis symmetrical, one test rod that is elongated rod shape structure has the insertion end that can insert in horizontal through hole, the length of described test rod is greater than the distance of the mid point of vertical through-bore axis to a two vertical pin rod, and the other end of described test rod is fixed with a test rod handle.
What axis hole and milling flat verticality detection frock mainly detected is the workpiece with milling flat and axis hole connectivity structure.In testing process, first workpiece for measurement is inserted in the vertical through hole on base, guarantees that milling flat is close to spacer and axis hole is aimed at the horizontal through hole on spacer.Then allow the insertion end of test rod be inserted in the horizontal through hole on spacer by axis hole.At the other end of test rod, observe the position relationship of test rod and vertical pin rod.If test rod through the mid point of two vertical pin rods, represent axis hole and milling flat verticality high.If test rod is partial to vertical pin rod, axis hole and milling flat out of plumb are described.According to test rod, be partial to the degree size of vertical pin rod, can intuitive judgment axis hole and the requirement such as the whether satisfied processing of verticality of milling flat, assembling.
The present invention utilizes a test rod that is far longer than axis hole length, and the minute angle that has expanded axis hole and milling flat changes the change in location on the limit of bringing, and by the location comparison with vertical through-bore axis, intuitively, fast workpiece has been carried out to verticality detection.
As preferably, described base is provided with a horizontal tapped through hole, and described horizontal tapped through hole is coaxial with described horizontal through hole, and a fixed bar and described horizontal screw thread through hole whorl match, and described fixed bar is provided with fixed bar handle.
In use put into after workpiece for measurement, turn fixed bar, fixed bar is compressed workpiece for measurement near vertical through hole one end, thereby fix workpiece.Complete after testing, unscrew fixed bar, just can take out workpiece.On fixed bar, be provided with fixed bar handle, make easily to turn fixed bar.The effect of fixed bar, makes stable being placed in axis hole and milling flat verticality detection frock of workpiece for measurement, prevents that the slight jitter and the displacement that in operating process, produce from exerting an influence to testing result.
As preferably, described fixed bar is smooth sphere structure near the vertical end of through hole.Smooth sphere structure can protect workpiece for measurement to avoid damage and wearing and tearing.
As preferably, described spacer is flat rectangular structure.Spacer and perpendicular are fixed by two screws.Adopt flat rectangular structure, can allow spacer in lower end, have a plane to contact with horizontal plane, can allow the placement of spacer more stable.
As preferably, the axis that the length of described test rod is greater than described vertical through hole is provided with the distance of an end margin of vertical pin rod to base.In actual measuring process, test bar be extracted or be inserted to the backstay that exceeds base edge can aspect user.
As preferably, the insertion end of described test rod is that tapering is the truncated cone-shaped structure of 1: 250~1: 400.Truncated cone-shaped structure makes test rod front end occur tapering, has the test rod of tapering can easily be inserted in the horizontal through hole of spacer and goes.
As preferably, described test rod is made by Hardmetal materials.In detecting the verticality process in axle milling flat and hole, workpiece to be detected is all metal material, is easy to cause wearing and tearing to detecting frock in testing process.Meanwhile, in testing process, whether test rod is straight very important to testing result.Test rod adopts Hardmetal materials, makes in long-term use procedure, has improved the wear-resistant ability of test rod, has extended serviceable life.Hardmetal materials is not easy distortion, has guaranteed the accuracy of testing result.
As preferably, the length of described test rod handle is symmetrical about the axis of test rod.Symmetrical test rod handle, makes the movement of test rod steady.
Therefore, the present invention has conveniently, observes intuitively the verticality relation of axis hole and milling flat, can fast and stable fixing workpiece for measurement, the feature such as frock is wear-resistant.
