Description
Technical field
The utility model relates to frock clamp, particularly relates to a kind of metallographic sample preparation process time saving and energy saving, and can improve the metallographic sample preparation frock clamp of sample preparation efficiency and security.
Background technology
Metallographic Analysis is one of important means of metal material experimental study, adopt quantitative metallography principle, the three dimensions pattern of alloy structure is determined by the measurements and calculations of the metallographic microstructure of two-dimentional metallographic specimen flour milling or film, thus the quantitative relationship set up between alloying component, structure and properties, first sample when carrying out Metallographic Analysis to metal, and the rough surface of sampling and irregular contour sample are repaired shaping, namely according to inspection object determination flour milling direction, and by smooth for its reconditioning, namely carry out metallographic corase grind.Existing metallographic rough grinding pass generally takes hand-held test block to grind, grind metallographic test block not only very easily hot or slippage in process, thus injure operator, and it is long owing to adopting this kind of method to grind the time, sample preparation efficiency is low, wastes time and energy, simultaneously due to hand-held poor stability, easily cause test block to occur multi-surface, add the difficulty that metallographic grinds.
Summary of the invention
The utility model mainly provides that a kind of structure is simple, metallographic sample preparation process is time saving and energy saving, quality good, and the metallographic sample preparation frock clamp of sample preparation efficiency and security can be improved, solve when metallographic sample preparation is carried out in the hand-held test block existed in prior art waste time and energy, sample preparation efficiency is low, of poor quality, and test block grinds easily hot or slippage in process, thus cause the technical problem of security incident etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of metallographic sample preparation frock clamp, comprise the circular positioning pipe being set in metallographic sample preparation one end, the outer wall of circular positioning pipe spins hold-down bolt, and the screw terminal of hold-down bolt passes the wall apical grafting of circular positioning pipe on the surface of metallographic sample preparation.One end of metallographic sample preparation is inserted one end of circular positioning pipe, be crimped on the surface of metallographic sample preparation in the mesopore that the hold-down bolt be screwed on circular positioning pipe outer wall extends to circular positioning pipe, metallographic sample preparation is made to be clamped in the mesopore of circular positioning pipe, during metallographic corase grind, the hand-held circular positioning pipe other end relative with metallographic sample preparation can be processed, structure is simple, because metallographic sample preparation and circular positioning pipe are a linear contact lay, the heat that in rough grinding pass, test block produces only has a little branch to conduct to circular positioning pipe, therefore there will not be the phenomenon of scalding operator, clamping is pressed by circular positioning pipe internal face and hold-down bolt, good stability, Grinding Process is safe and reliable, and sample making course is time saving and energy saving, quality is good, efficiency is high.
As preferably, at the bottom of the circular positioning pipe other end relative with described metallographic sample preparation is packaged with tin, at the bottom of cylinder, be connected with positioning bolt, the screw terminal of positioning bolt through apical grafting at the bottom of cylinder on the inner side end of metallographic sample preparation.At the bottom of arranging in the bottom of circular positioning pipe tin, and at the bottom of cylinder on positioning bolt is set, both stretched into the metallographic sample preparation length in circular positioning pipe mesopore by positioning bolt regulable control, the position of test block can have been fixed again further, prevent it from grinding play before and after in process, improve stability.
As more preferably, at the bottom of described positioning bolt is coaxially screwed in tin.Guarantee the medial extremity stable support of bolt at metallographic sample preparation of transposing.
As preferably, be less than circular positioning pipe internal diameter 2mm to 5mm corresponding to the metallographic sample preparation width in described circular positioning pipe.Rational gap is set between metallographic sample preparation and circular positioning pipe inwall, rocking of test block can be reduced, improve crudy.
As preferably, described hold-down bolt is radially screwed on the circular positioning pipe outer wall of metallographic sample preparation end.Can guarantee when hold-down bolt radially spins that its top is pressed in the middle part of metallographic sample preparation, guarantee that test block location is reliable; Hold-down bolt is positioned on the circular positioning pipe of metallographic sample preparation side, is convenient to the other end of hand-held circular positioning pipe, reduces the multiaspect phenomenon ground in process, increases work efficiency and quality.
Therefore, metallographic sample preparation frock clamp of the present utility model has following advantage: the working (machining) efficiency and the security that improve metallographic sample preparation: the gripping sense improving sample in sample making course, avoids test block to fly out and hurts sb.'s feelings; Avoid because hot or test block skidding injure operator's finger and affect operating efficiency or scald; Make operating personnel's health relatively away from grinding wheel, improve the security ground in process.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of metallographic sample preparation frock clamp of the utility model.
Detailed description of the invention:
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of metallographic sample preparation frock clamp of the present utility model, comprise the circular positioning pipe 1 being set in metallographic sample preparation one end, circular positioning pipe 1 internal diameter 2.5mm is less than corresponding to the metallographic sample preparation width in circular positioning pipe 1, circular positioning pipe 1 outer wall near metallographic sample preparation side radially spins a hold-down bolt 2, the screw terminal of hold-down bolt 2 is connected on the surface of metallographic sample preparation through the wall vertical top of circular positioning pipe 1, at the bottom of circular positioning pipe 1 other end relative with metallographic sample preparation is welded tin 3, at the bottom of cylinder, the middle part of 3 spins a positioning bolt 4, the screw terminal of positioning bolt 4 passes 3 apical graftings at the bottom of cylinder in the middle part of the inner side end of metallographic sample preparation.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
