Description

A kind of cylindrical measurement servicing unit of thin-wall part
Technical field
It the utility model is related to a kind of servicing unit of the cylindrical measurement of thin-walled.
Background technology
Sleeve as shown in Figure 1, such as:Bushing, grommet etc., such part wall thickness is thin, and its cylindrical and cylinder ring coordinates, therefore right Cylindrical processing dimension is required, and when examining part outside diameter, we are surveyed usually using clamp as shown in Figure 2 Amount.Thin-wall part, due to the effect of external force, is easily deformed it in cargo handling process is processed, but this part is in use state When inside held round equipped with rod member, as long as so its excircle dimension it is qualified be just certified products, and directly surveyed at present with clamp 8 Amount, measurement inaccuracy is easily caused, part certified products is mistaken for waste product, direct economic loss is brought to enterprise.
The content of the invention
The purpose of this utility model is to overcome the above-mentioned technological deficiency existing for the clamp measurement cylindrical measurement of thin-wall part, carried For a kind of servicing unit that can meet its accurate measurement thin-wall part outside diameter, erroneous judgement is reduced, improves economy.
Technical scheme is a kind of cylindrical measurement servicing unit of thin-wall part used by the utility model, its be characterized by it by Mandrel, nut, pad, the spring that rises, fixed block, bottom plate composition, mandrel are two-stage structure, and upper end is the screw rod being engaged with nut, The outer surface of lower end is up-small and down-big cone, and four square holes being engaged with fixed block are machined with the center of lower surface, fixed Block is tetragonal prism, and one end is fixed on bottom plate, and the other end is connected with mandrel, and the spring endoporus that rises is the taper hole being engaged with mandrel, is covered In outside the cone of mandrel lower end, the outer surface for the spring that rises is the cylinder being engaged with inner bore of part to be measured, and pad is in nut and risen Between spring, the diameter of pad is more than the internal diameter for spring upper surface of rising, less than the external diameter for the spring that rises.
Its bottom of mandrel in the utility model is milled with square hole and fixed block square shaft and coordinated, and during tightening nut, can prevent two Rotated between person, while also allow for loading and unloading.Bottom plate is fixed on the table, and part is inserted in into the spring that rises during use, manual with Flexible spanner Nut, pad is promoted to be pressed into the spring that rises, in the presence of mandrel taper, so that the spring harmomegathus that rises reaches tensioner workpiece, realization is held round With clamping, reach the purpose of artificial adjustment deformation, unload fixed block part afterwards, measured using clamp.
The upper/lower terminal of spring of rising all is provided with 2-6 bars and risen groove vertically, and the length for the groove that rises is the 1/2-4/5 of spring length of rising.This Utility model is gentle to the recuperation of part to be measured, not injuring part.
Circular hole is machined with the end for the groove that rises, the groove that rises connects with circular hole, and the groove that rises has identical center line, circular hole with circular hole Diameter be more than the width of groove of rising.
2 times of a diameter of well width that rises of circular hole.
The utility model has the advantage of:It is simple in construction, it is easy to operate, nut is turned by monkey wrench and realizes that the spring that rises supports Circle, reaching artificial correcting deformed purpose, the device is easily realized, and can meet that requirement makes measurement result accurate, reduces erroneous judgement, Improve economy.

Wherein:The pad 4 of 1 mandrel, 11 screw rod, 12 cone, 13 4 square hole, 2 nut 3 circular hole 5 of groove 42 that rises of spring 41 that rises is fixed 6 bottom plate of block, 7 clamp of part 8 to be measured.
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 Solve the utility model
As seen in figures 3-6, the cylindrical measurement servicing unit of a kind of thin-wall part, it is by mandrel 1, nut 2, pad 3, the spring 4 that rises, solid Determine block 5, bottom plate 6 forms, mandrel 1 is two-stage structure, and upper end is the screw rod 11 being engaged with nut 2, and the outer surface of lower end is upper Small lower big cone 12, four square holes 13 being engaged with fixed block 5 being machined with the center of lower surface, fixed block 5 is tetragonal prism, By being fixedly welded on bottom plate 6, the other end, which is inserted in four square holes 13, to be realized with the connection of mandrel 1 for one end, the endoporus of spring 4 that rises be with The taper hole that mandrel 1 is engaged, it is placed on outside the cone 12 of the lower end of mandrel 1, the outer surface for the spring 4 that rises is to be engaged with inner bore of part to be measured Cylinder, be typically chosen and be slightly less than inner bore of part to be measured, the upper/lower terminal of the spring 4 that rises all is provided with 2-6 bars and risen groove 41 vertically, this It is each 5 up and down in figure, the length for the groove 41 that rises is the 1/2-4/5 of spring total length of rising, and the groove 41 that rises circumferentially is evenly arranged, and is handed over up and down Poor equi-spaced apart arrangement.Be machined with circular hole 42 in the end for the groove 41 that rises, the groove 41 that rises connects with circular hole 42, the center line for the groove 41 that rises with Point-blank, the diameter of circular hole 42 is more than the width for the groove 41 that rises to the center line of circular hole 42, the diameter of circular hole 42 in the application For 2 times of the width of groove 41 that rises.Pad 3 is in nut 2 between the spring 4 that rises, and the diameter of pad 3 is more than the internal diameter for the upper surface of spring 4 of rising, Less than the external diameter for the spring 4 that rises.After fixed block 5 welds with bottom plate 6, bottom plate is fixed on the table, and rise spring internal taper hole and mandrel taper Coordinate, locked using nut, pad, slid by the elastic spring that makes to rise of adjusting nut on mandrel, realization holds round and loaded and unloaded;Mandrel The square hole of bottom coordinates with fixed block square shaft, both when preventing elastic between relatively rotate.
Part 7 to be measured is inserted in the spring that rises during use, with Flexible spanner manual nut, promotes pad to be pressed into the spring that rises, is bored in mandrel In the presence of degree, so that the spring harmomegathus that rises reaches tensioner workpiece, realization holds round and clamped, and reaches the purpose of artificial adjustment deformation, Fixed block and bottom parts are unloaded afterwards, as shown in fig. 6, recycling the external diameter of clamp measurement part 7 to be measured.
