The detection fixture huge number of the right alignment of current measurement part, there is a kind of coaxiality check fixture, comprise inspection grip assembly and inspection rod, the scroll chuck formula mechanism that described inspection grip assembly comprises the base plate be sleeved on inspection rod, cover plate and is arranged between base plate and cover plate, described scroll chuck formula mechanism comprises screw knob and three claws, three claws are all threaded with screw knob, three claws make coaxially equidistant stretching motion under the effect of screw drive, and the end of three claws is on same circle; Inspection rod is also provided with clock gauge.This cubing can measure the coaxiality error between the Kong Yukong of hole type parts, but, this cubing is in measuring process, part is needed to rotate, adopt above-mentioned cubing, produce larger friction between the inwall meeting of part rotating hole and jaw, on the one hand easily make hole in piece part inwall damage, the rotation of another aspect part is owing to need overcome larger frictional resistance and inconvenient.
Utility model content
The utility model is intended to provide one can not cause damage to part inwall, and easy to operate right alignment detects built-up jig.
Right alignment in this programme detects built-up jig, comprise clip claw mechanism, locating shaft, testing agency, locating shaft is fixedly connected on clip claw mechanism, one end away from clip claw mechanism on locating shaft is connected with testing agency, described clip claw mechanism comprises jaw and clamping seats, the quantity of jaw at least three, and jaw is threaded on clamping seats, the bare terminal end of jaw is provided with roller, and the axial line of described locating shaft and the geometric center of clamping seats side coincide; Described testing agency comprises the detection seat being connected to locating shaft one end, and is arranged on and detects clock gauge on seat and detection head.
Beneficial effect: before detection, rotation jaw tightens up, tested part is enclosed within jaw, rotate jaw and carry out tensioning, note ensureing that each jaw upper roller center is identical to clamping seats centre distance in tensioning process, the hole of jaw clamping is datum hole, detection head is adjusted in measured hole, detection head is just contacted with measured hole inwall, and clock gauge is set to zero, rotate tested part, detection head is slided in measured bore, read reading, the maximum registration of appearance is the coaxiality error of this hole and datum hole.Adopt the program, jaw is provided with roller, in measuring process, the slip of jaw and part inwall is converted into rolling, reduces the friction between jaw and part inwall, prevent part from occurring scratching, decrease frictional resistance simultaneously, operate more laborsaving convenience.
Further, described detection cover for seat is connected on locating shaft, and the outer wall of detection seat is connected with the clamping screw that locking detects seat.Regulate the axial displacement detecting seat, to adapt to the part of different interior hole length.
Further, described detection seat is provided with chute, and clock gauge and detection head are arranged on and are positioned on the slide block of this chute, and detection seat is also connected with the adjusting bolt for locking sliding block, end and the slide block of adjusting bolt push against.For the endoporus of different-diameter, can by regulating the height of detection head to adapt to the detection of different size endoporus.
Further, the end of described jaw is rotationally connected wheeled base, and roller is rotatably connected on wheel seat, and ensure that roller can not be followed jaw and together be rotated, impact detects hardness.
Further, the quantity of described jaw is three, and structure is simple, can reach the locating effect of part simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model right alignment detects built-up jig embodiment;
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: clamping seats 1, jaw 11, wheel seat 12, roller 13, locating shaft 2, detection seat 3, clock gauge 31, slide block 311, adjusting bolt 312, clamping screw 313, detection head 32, part 4.
Embodiment is substantially as shown in Figures 1 and 2:
Right alignment in this programme detects built-up jig, comprise jaw 11 mechanism, locating shaft 2, testing agency, locating shaft 2 is fixedly connected in jaw 11 mechanism, locating shaft 2 is connected with testing agency away from one end of jaw 11 mechanism, described jaw 11 mechanism comprises jaw 11 and clamping seats 1, the quantity of jaw 11 is three, jaw 11 is threaded on clamping seats 1, the end of jaw 11 is provided with wheel seat 12, jaw 11 is through clamping seats 1, on jaw 11, the two ends of clamping seats 1 are processed with convex shoulder respectively, carry out spacing between the wall of clamping seats 1 is sandwiched in, roller 13 is arranged on wheel seat 12.Testing agency comprises the detection seat 3 being connected to locating shaft 2 one end, and is arranged on and detects clock gauge 31 on seat 3 and detection head 32.
