Description
Technical field：
The utility model is related to a kind of Thin-wall cylindrical part coaxality measurement servicing unit.Be particularly suitable for use in thin wall tubular shape
The servicing unit of part measurement.
Background technology：
My Products part has many Thin-wall cylindrical parts such as Fig. 1, in coaxality measurement, and used axiality is surveyed
Instrument is measured as shown in Fig. 2 being positioned using one end end face, the spring that rises is clamped, the other end is the metering system of cantilever.As production needs,
Part length is lengthened, and because deadweight causes tail drop, causes the data measured unstable, it is impossible to reach measurement request.
The content of the invention：
The purpose of this utility model is to overcome above-mentioned technological deficiency to meet accurate measurement axiality requirement there is provided one kind
The Thin-wall cylindrical part coaxality measurement servicing unit used cooperatively with existing axiality measuring apparatus.
The technical scheme that the utility model is used is a kind of Thin-wall cylindrical part coaxality measurement servicing unit, its main points
Be it include top, bearing gland, radial ball bearing, positioning sleeve, thrust ball bearing, top body, sleeve, front pedestal, block,
Screw rod, handle, bottom plate composition, front pedestal are bolted on bottom plate, and screw rod is fixed in front pedestal by two and half shape blocks,
The inner is connected with sleeve, and the front end of sleeve connects with top body phase, and handle is connected with screw rod outer end, and its circumference outer surface is provided with axle
To chute, there is alignment pin to be fixed in front pedestal, top is engaged with axial slide, the rotation of screw rod becomes the movement of sleeve,
Top to be connected with top body by radial ball bearing, positioning sleeve, thrust ball bearing, the end face of top body is fixed with bearing pressure
Lid, so as to realize that the rotation of screw rod drives whole top move forward and backward.
The utility model is on the basis of existing axiality measuring apparatus, to add measurement servicing unit, to the tail of part
End is supported, and overcomes the defect of tail drop, improves measurement accuracy.
The utility model has the advantage of：It is simple in construction, it is easy to operate, the rotation of screw rod is driven by handle, it is final real
Existing top axial translation Clamp blocks, are applicable to the part of different length, make the relatively reliable stabilization of positioning, and measurement result is accurate
Really.

Wherein 1, top 2, bearing gland 3, radial ball bearing 4, positioning sleeve 5, thrust ball bearing 6, top body 7, sleeve
71st, axial slide 72, alignment pin 8, front pedestal 9, block 10, screw rod 11, handle 12, bottom plate.
Embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings, professional and technical personnel can be made more to manage
Utility model is solved, following embodiments is modified, it is all possible to add and replace, all without departing from of the present utility model
Protection domain.
As shown in Figure 3,4, a kind of Thin-wall cylindrical part coaxality measurement servicing unit, it is to coordinate existing coaxality measurement
Instrument is used together, and it includes top 1, bearing gland 2, radial ball bearing 3, positioning sleeve 4, thrust ball bearing 5, top body 6, sleeve
7th, front pedestal 8, block 9, screw rod 10, handle 11, bottom plate 12 are constituted, and front pedestal 8 is bolted on bottom plate, and screw rod 10 is by two
Individual half shape block 9 is fixed in front pedestal 8, the inner be connected with sleeve 7, the front end of sleeve 7 is connected with top body 6, handle 11 and
The outer end of screw rod 10 is connected, and the circumferential outer surface of sleeve 7 is provided with axial slide 71, has alignment pin 72 to be fixed in front pedestal 8, top with
Axial slide 71 is engaged, and prevents sleeve from rotating, and the rotation of screw rod becomes the axial movement of sleeve 7, and top 1 leads to top body 6
Cross radial ball bearing 3, positioning sleeve 4, thrust ball bearing 5 to be connected, the end face of top body 6 is fixed with bearing gland 2, so as to realize
The rotation of screw rod drives whole top movable, flexible rotating between top 1 and top body 6.
Screw rod in the utility model is fixed in front pedestal by two semicircle blocks, and sleeve is housed in front pedestal, led to
Cross handle and rotate screw rod, its circumference outer surface is provided with the cooperation of longitudinal chute and alignment pin, makes the rotation between screw rod and sleeve
Turn band moving sleeve to move forward and backward.The endoporus of top body is equipped with radial ball bearing and thrust ball bearing, and outer ring and the endoporus of bearing are matched somebody with somebody
Close, separated between bearing with positioning sleeve, the inner ring of bearing coordinates with top, is locked by bearing gland on top body, real
The flexible rotating and top 1 for showing tail centre are axially fixed at top body 6.Top body is by Morse's taper and sleeve taper fit, set
Cylinder drives top body translation, finally realizes top translation.
Operation principle of the present utility model, the utility model is fixed on bottom plate 12 together with axiality measuring apparatus, will
One end of part to be measured is connected with axiality measuring apparatus, and handle drives screw rod to rotate, because alignment pin 72 is stuck in axial slide 71
In, sleeve can only be moved forward and backward, and drive top move forward to hold out against the other end of part, now piece surface is measured, measure
During part it is free to rotate.
