Description
Technical field
The utility model relates to a kind of pick-up unit, specifically a kind of device of detection laser welding diamond tool weld strength.
Background technology
The utilization more and more widely of diamond tool quilt for the sake of security, has been formulated the examination criteria of diamond tool weld strength in the world.What instrument to check its intensity with is the problem that each diamond tool factory must consider.At present, the device that lacks the diamond tool of detection laser welding easily and fast weld strength on the market.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can satisfy the detection laser welding diamond tool weld strength of above-mentioned requirements, and this apparatus structure is simple, and is easy to operate, can fast detecting laser welded diamond tool weld strength.
For realizing above-mentioned utility model purpose, a kind of device of detection laser welding diamond tool weld strength, comprise chuck and elastic rod, it is characterized in that: described chuck comprises the upper and lower chuck that is flexibly connected by connecting link, have hole with the level on the chuck, the spring and the set screw that are used for adjustable clamp draught animals footpath are housed in the hole; One end of elastic rod is fixed on the lower chuck, and the other end is equipped with handle, and dial gauge is fixed on the elastic rod by bearing, and its expansion link contacts with chuck.
Characteristics of the present utility model are that volume is little, and structure is light and handy, can be useful for the check of the saw blade tip weld strength of variety classes, different-thickness and size.Easy to use, low price.

Embodiment
This pick-up unit inventor is referred to as torque spanner, is the torsion pincers again, is actually a torsional moment structure.Its structure as shown in Figure 1.Compositions such as upper and lower chuck 1,12, elastic rod 6, dial gauge 3, bearing 4.Upper and lower chuck flexibly connects by connecting link 14, vertically has " " type hole on chuck, and spring 13 and set screw 2 are housed in the hole, and set screw 2 can be regulated the bore of chuck, to adapt to the cutter head of different-thickness.One end of elastic rod 6 is fixed on the chuck, and the other end is equipped with handle 5.Dial gauge is fixed on the elastic rod 6 by bearing 4.The effect of bearing is fixing dial gauge, and bearing need not move after the position on the elastic rod mixes up generally speaking, and elastic rod under the effect of power deflection takes place, thereby the pointer that drives dial gauge deflects, elastic rod reaches chuck with power, makes cutter head stressed, and weld seam produces moment of flexure.What and the direct proportion that is deformed into of elastic rod of the needle deflection of dial gauge, and the distortion of elastic rod is relevant with the size of power, thus pass through the size of the needle deflection situation energy measurement power of dial gauge.
The measuring principle of this device is when measuring weld strength, can regard elastic rod as a semi-girder, is subjected to after the power that chuck transmits deflection taking place, and whole process is illustrated with Fig. 2.If the distance that dial gauge is ordered from A is X, deflection and corner that this takes place under the F3 effect are:
The amount of deflection of bar is: δ=(F
3L
3X
2/ 2-F
3X
3/ 6)/EI (7)
Angle is: θ=(F
3L
3X-F
3X
2/ 3)/maximum defluxion and the hard-over of EI (8) elastic rod occur in the end, for:
Maximum defluxion: δ
Max=(F
3* L
3 3)/2EI
Hard-over: θ
Max=(F
3* L
3 2)/2EI
Annotate: the deflection Δ L=AB-X of the bendind rigidity bar of El---beam
As shown in Figure 2: certain for X, F3 is big more, and δ is big more, and θ is big more, and AB is big more, and then Δ L is big more, can detect the size of F3 by Δ L, i.e. the size of M detects the bending strength of weld seam thus.In addition, under the effect of same power F3, X is big more, and promptly the dial gauge distance of ordering from A is far away more, and δ is big more, and θ is big more, and AB is big more, and promptly the reading of dial gauge is big more, also means big more to the enlargement factor of power.So, can come the demonstration multiple of realizable force by the position of regulating dial gauge to different occasions.
Determining of dial gauge reading: in elastic range, power that torque spanner handle center is executed and dial gauge reading are approximately linear dependence to be changed.Apply the reading that certain power makes dial gauge in torque spanner handle center and be respectively 5,10,15,20, peek is learned average, calculates the size of the power of each little lattice representative of dial gauge, with this as standard.
According to the different size of various tool,, calculate the size of Laser Welding (LBW) instrument weld seam checker's required power that applies on the handle of torque spanner when meeting the intensity level of DSA standard according to some formula of the DSA standard and the mechanics of materials; And then do standard according to the power of the every little lattice representative of dial gauge, determine when check the reading that should show on the dial gauge.
The using method of said apparatus as shown in Figure 3,
1) saw blade 15 is enclosed within on the central shaft 9 of same specification, is placed horizontally on the check-out console, press cover plate 10;
2) chuck 1,12 of torque spanner is clamped the cutter head of required check, right hand handle 5 is upwards firmly pulled, and swings to up to dial gauge 3 till the reading of regulation; Firmly pull downwards again, swing to up to dial gauge till the reading of regulation; If do not fall tooth, illustrate that promptly the weld seam of this cutter head satisfies the DSA standard, this cutter head is qualified.If fall tooth, illustrate that promptly the weld seam of this cutter head does not satisfy the DSA standard, this cutter head is defective, must reprocess.
3) rotate saw blade to next cutter head, repeating step 2 is till all cutter heads of whole saw blade have all inspected.
4) check other saw blade by 1 ~ 3 step again.
The also similar said method of the check of other parts such as drill bit.
