Abstract

The utility model relates to a measuring tool, in particular to a measuring tool which can be used to check axial verticality and height simultaneously and solves the problems of an existing measuring tool that the operations are trivial and waste time and labor, the measurement error is big, and the like. The measuring tool comprises a base and a center frame, wherein a percentage meter is arranged on the center frame, a measuring plate is fixed on the top end of the center frame, a through hole is arranged on one end of the measuring plate, a measuring post which is matched with the through hole precisely in a sliding mode is arranged in the through hole, the upper end surface of the measuring post is in a step shape, the base is in a V shape, side touch boards are respectively arranged on relative positions inside the base, and a supporting nail is additionally arranged under the base. The measuring tool is used to measure the verticality and the height size of a shaft which is pressed in a hole precisely and simultaneously, the measuring demands of obtaining the practical size of workpieces rapidly and accurately in time are realized, subsequent processing parameters are adjusted in time, the checking cost and period are reduced, the technological requirements of timely measurement are satisfied, and the measurement precision can guarantee the precision demands of product drawings completely, and the measuring tool provides accurate and reliable measurement technical support for mass production.

Description

Detect axle verticality and measurer highly simultaneously

Technical field

The utility model relates to a kind of survey instrument, is specially a kind of axle verticality and measurer highly of detecting simultaneously.

Background technology

Known, in the axial compression hand-hole, should guarantee the axle and the verticality of hole end surface, guarantee the height dimension of axle again, if detection respectively to hole end surface, operate comparatively loaded down with trivial details, main detection method has following two kinds at present: the one, utilize the three-dimensional detector to detect: the precision height, the expense height, the cycle is long, survey crew will possess certain qualification and technical ability, and workpiece must unload and could detect from lathe; The 2nd, utilize universal standard measurer to detect: detect height with height gauge earlier, use angle square, clearance gauge detection of vertical degree again, there is bigger measuring error in not only complex operation step, and this measuring method.

Summary of the invention

There is complex operation in the utility model, wastes time and energy in order to solve the existing measurer that detects axle verticality and height simultaneously, and problem such as measuring error increasing, and a kind of measurer that detects axle verticality and height simultaneously is provided.

The utility model is to adopt following technical scheme to realize: the measurer that detects axle verticality and height simultaneously, comprise base and be fixed on centre frame on the base, dial gauge is set on the centre frame, the centre frame top is fixed with the measurement plate, measure plate one end and have through hole, the measurement column that is slidingly matched with its precision is set in the through hole, and the measurement column upper surface is step-like, is respectively appear on the stage terrace and leave from office terrace.Measurement column with measure plate on can be as the criterion cooperating of through hole along the activity of through hole easy on and off with measurement column, to guarantee that promptly screw thread cooperates size suitably; The difference in height of upper and lower step surface is axial compression and goes into the height tolerance size; Described dial gauge is existing known survey instrument, and its concrete structure and measuring principle, method are that those of ordinary skill in the art knows.

During use base is placed on the hole end surface, then the gauge head of the dial gauge on the centre frame is pushed down the periphery and the zeroing of axle, base is pivoted a week, observe the dial gauge reading, be i.e. the verticality of axial compression hand-hole as can be known; The measurement column lower end of centre frame upper end contacts with the axle upper surface simultaneously, makes measurement column move up and down in measuring plate, if the upper and lower step surface of measurement column upper surface is being measured between the plate, axial compression goes into highly promptly to meet the requirements so.

Compared with prior art, the utility model is used for verticality and the height dimension that simultaneously accurate measurement axis is pressed into the hole, realized obtaining the measurement requirement of workpiece physical size fast, accurately, in good time, in time adjust the following process parameter, reduce testing cost and cycle, satisfied the technological requirement of in good time measurement; And measuring accuracy can guarantee the accuracy requirement of product drawing fully, for production in enormous quantities provides accurately, measuring technique support reliably.

Embodiment

Detect axle verticality and measurer highly simultaneously, as shown in Figure 1, comprise base 1 and be fixed on centre frame 2 on the base 1, as shown in Figure 3, dial gauge 3 is set on the centre frame 2, dial gauge is threaded with centre frame, need not make at measurer, be convenient to the dismounting of dial gauge, centre frame 2 tops are fixed with measures plate 4, measures plate 4 one ends and has through hole 5, the measurement column 6 that is slidingly matched with its precision is set in the through hole 5, as shown in Figure 4, measurement column 6 upper surfaces are step-like, are respectively appear on the stage terrace 7 and leave from office terrace 8;

In order further to optimize structure of the present utility model, base 1 is V-shaped, is convenient to be placed on 12 end faces of hole; A nail 9 is set up in base 1 below, can reduce the friction of base and hole end surface, also can be convenient to easily move this measurer; As shown in Figure 2, base 1 inboard relative position is provided with side touch panel 10 respectively, during measurement, can reduce the measurer wearing and tearing in long-term measuring process with the side touch panel near axle 11.

The size between a plate and the nail is measured in principal security when this measurer is made, i.e. height is gone in axial compression, and the measured axial compression of each measurer goes into highly to determine, so this measurer can be made into series of products, to satisfy the needs of different occasions.
