Abstract
The invention discloses an auxiliary tooling for a portable hardometer, which comprises a standing pole, a detecting flat-plate sliding along the standing pole is arranged on the standing pole, and a guide rod is vertically fixed at the lower part of the standing pole; and the guide rod is sleeved with a support frame for supporting the standing pole on a workpiece, and a centrobaric ball is hung below the guide rod by a fine line. The auxiliary tooling disclosed by the invention has the advantages of simple structure and low manufacture cost, and solves the problem that the highest point on the cylindrical face of the surface of a shaft neck of a cam shaft is difficult to be found by the portable hardometer, so that inaccurate detection is caused.
Description
Technical field
The present invention relates to a kind of tooling for measuring hardness, more particularly, it relates to a kind of portable hardometer auxiliary mould.
Background technology
Originally the sclerometer in workshop is fixing bench mounted hardness tester, and has certain limit to limit to the diameter of the outside cylinder of camshaft, directly causes the large-scale camshaft of part cannot use this sclerometer.And portable hardometer hand-held stability in centering face of cylinder peak and testing process has larger difficulty, so that have inaccurate when detecting.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned deficiency for prior art, provides a kind of portable hardometer auxiliary mould, and this auxiliary mould can find the peak of cam face fast, detects the hardness of camshaft, and structure is simple, easy to carry.
Technical scheme of the present invention is such: a kind of portable hardometer auxiliary mould, comprises vertical rod, and it is dull and stereotyped that described vertical rod is provided with the detection slided up and down along vertical rod, is fixed with a guide rod in vertical rod lower vertical; On described guide rod, cover has one for vertical rod being supported on the bracing frame on workpiece, is provided with the center of gravity ball by fine rule hanging below guide rod.
Further, described bracing frame is the annular solid of upper opening, and described detection flat board is positioned at the upper opening portion of bracing frame.
Further, support frame as described above lower inside both sides are respectively equipped with the cushion block for supporting workpiece, are respectively equipped with the second screw be fixed on by bracing frame on workpiece on the both sides, upside of bracing frame.
Further, described detection flat board is provided with the open slot being convenient to determine to detect position.
Further, described detection flat board passes through the first screw lock in vertical rod.
Beneficial effect
Compared with prior art, structure of the present invention is simple, easy to manufacture, easy to install, easy to carry, is applicable to the hardness determination at different occasion, different size camshaft in the present invention; Effectively can solve the problem swung when portable hardometer is difficult to centering face of cylinder peak and checks, the hardness of camshaft can be detected easily and quickly, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the front view of portable hardometer auxiliary mould of the present invention;
Fig. 2 is the left view of portable hardometer auxiliary mould of the present invention;
Fig. 3 is the vertical view of portable hardometer auxiliary mould of the present invention.
In figure: 1, the first screw, 2, detect dull and stereotyped, the 3, second screw, 4, bracing frame, 5, cushion block, 6, vertical rod, 7, fine rule, 8, center of gravity ball, 9, guide rod.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Embodiments of the invention are such: as shown in Figures 1 to 3, a kind of portable hardometer auxiliary mould, comprise vertical rod 6, vertical rod 6 is provided with the detection flat board 2 slided up and down along vertical rod 6, detect dull and stereotyped 2 and be provided with screw, can be locked by the first screw 1 and be fixed in vertical rod 6 detecting dull and stereotyped 2, unscrew the first screw 1 and detection dull and stereotyped 2 can be allowed to slide up and down along vertical rod 6, to adapt to the bent axle hardness determination of different-diameter; Detecting the open slot being provided with on dull and stereotyped 2 and being convenient to determine to detect position, the convenient points hardness of portable hardometer to workpiece of placing is detected; Be fixed with a guide rod 9 in the lower vertical of vertical rod 6, on described guide rod 9, cover has one for vertical rod 6 being supported on the bracing frame 4 on workpiece, and bracing frame 4 can slide on guide rod 9, to adapt to different measuring positions; Bracing frame 4 in the present embodiment is the annular solid of upper opening, is convenient to bracing frame 4 to be enclosed within crankshaft end, and described detection flat board 2 is positioned at the upper opening portion of bracing frame 4; The center of gravity ball 8 by fine rule 7 hanging is provided with below guide rod 9; Vertical rod 6 can be made to remain vertical state.
In the present embodiment, support frame as described above 4 lower inside both sides are respectively equipped with the cushion block 5 for supporting workpiece, slide for preventing bracing frame 4; Be respectively equipped with the second screw 3 be fixed on by bracing frame 4 on workpiece on the both sides, upside of bracing frame 4, bracing frame 4 is fixed on workpiece by two the second screws 3.
When the present invention specifically uses, first cushion block 5 is fixedly connected with by lock-screw with bracing frame 4, bracing frame 4 is enclosed within guide rod 6, again detection dull and stereotyped 2 is installed in vertical rod 6, with fine rule 7, center of gravity ball 8 is hung in below guide rod 6, fine rule 7 and center of gravity ball 8 make vertical rod 6 keep vertical by center of gravity effect, at this moment adjust bracing frame 4, vertical groove on bracing frame 4 is overlapped with fine rule 7, ajusts bracing frame 4 with this.
Continue to keep frock to be in vertical state, bracing frame 4 is placed on camshaft mandrel end, located by cushion block 5, mobility detect dull and stereotyped 2 contacts with camshaft journal cylindrical, tightening the first screw 1 is fixed on detect dull and stereotyped 2 in vertical rod 6, even if at this moment detect the cam arc-shaped surface peak measurement range within the scope of dull and stereotyped 2 intermediate open channel, thus the peak obtaining cam face detects position, detects dull and stereotyped 2 and is in same level with arc surface peak; Then by tightening the second screw 3 stationary cam axle that bracing frame 4 top is symmetrical set, prevent camshaft from rolling, portable hardometer can be placed on reposefully and detect on dull and stereotyped 2, detects position carry out hardness determination to the cam face peak determined.It is simple that aid of the present invention has structure, carries easy to assembly, be applicable to the hardness determination at different occasion, different size camshaft; The detection position of cam face peak can be found out rapidly and accurately, all right stationary cam axle, prevent from testing process, occur that camshaft rotates or tilts, effectively ensure that the accuracy of testing result.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these all can not affect effect of the invention process and practical applicability.
