Abstract
The invention discloses a cylindrical surface hardness testing fixture which comprises a clamp, and is characterized in that a groove with a V-shaped cross section is formed in the clamp; the cylindrical surface hardness testing fixture also comprises a cylindrical probe aligned with the groove; and the probe comprises a conical tip aligned with the groove, and a cylinder which drives the probe to move to the groove. According to the cylindrical surface hardness testing fixture, a cylindrical workpiece is clamped by the V-shaped groove and is extruded through the probe, and the hardness of the surface of the workpiece is evaluated by checking the thrust of the driving cylinder; and after the detection, the probe is loosened, and the workpiece can be taken out. The whole device is simple in structure and high in efficiency, and the workpiece is prevented from being damaged.
Description
Technical field
The present invention relates to a kind of measurement jig, especially the measurement jig of face of cylinder surface of the work hardness.
Background technology
Cylindrical work is not easy to fix, and therefore not Easy Test is when especially carrying out hardness test to its surface.At present, employing be to utilize anchor clamps that workpiece is fixed, but the holding force of anchor clamps do not control well, easily surface of the work is caused damage; And the process of clamping and the anchor clamps that unclamp needs operations such as swivel bolt usually, slow, inefficiency.
Summary of the invention
In order to overcome this problem, the invention provides a kind of simple in structure, do not damage surface of the work, the tool of face of cylinder hardness test efficiently.
Technical scheme of the present invention provides a kind of face of cylinder hardness test tool, it comprises anchor clamps, it is characterized in that: the groove that on the described anchor clamps xsect to be set be the V font, it also comprises a cylindrical needle over against described groove, described probe comprises the conical tip over against described groove, and it also comprises the cylinder that the described probe of driving moves to described groove.
Preferably, also be provided with the measurement instrument of the described cylinder thrust of a detection on the described cylinder.
Preferably, described anchor clamps comprise columniform clamp body, and described groove is arranged on the end face of described clamp body.
Preferably, described clamp body does not arrange on the end face of described groove and the coaxial columniform boss that arranges of described clamp body.
Preferably, described probe is along the axis direction setting of described clamp body.
Preferably, described probe is made by wolfram steel.
A kind of face of cylinder hardness test tool of the present invention utilizes the groove of a V-shape to come the clamping cylindrical work, by a probe extruding workpiece, estimates the hardness of surface of the work by checking the thrust that drives cylinder then; After having detected, unclamp probe and can take out workpiece; Whole apparatus structure very simply, can not damage workpiece, and efficient height.
Description of drawings
Fig. 1 is the structural representation of a kind of face of cylinder hardness test tool of the present invention.
Embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of face of cylinder hardness test tool of the present invention comprises anchor clamps 10, and anchor clamps 10 comprise a columniform clamp body 12.The groove 14 that on the end face of clamp body 12 xsect to be set be the V font, a columniform boss 16 coaxial with clamp body 12 is set on another end face, boss 16 is in the circular hole (not shown) that is inserted on the operator's console (not shown), so that anchor clamps 10 are fixed on the operator's console, groove 14 up at this moment.Also comprise a cylindrical needle 18 over against groove 14, probe 18 comprises the conical tip over against groove 14, and probe 18 is made by relatively hard materials such as wolfram steel.Probe 18 is driven by cylinder (not shown) and moves to groove 14, also is provided with the measurement instrument (not shown) of a detection cylinder thrust on the cylinder.
Like this, just can when detecting workpiece be placed in the groove 14, the tip of air cylinder driven probe 18 is pushed to surface of the work, by checking the reading on the impression of surface of the work and corresponding measurement instrument, can draw the hardness of surface of the work, and is very convenient.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Claims (6)
1. face of cylinder hardness test tool, it comprises anchor clamps, it is characterized in that: the groove that on the described anchor clamps xsect to be set be the V font, it also comprises a cylindrical needle over against described groove, described probe comprises the conical tip over against described groove, and it also comprises the cylinder that the described probe of driving moves to described groove.
2. hardness test tool in the face of cylinder according to claim 1 is characterized in that: the measurement instrument that also is provided with the described cylinder thrust of a detection on the described cylinder.
