Abstract

The utility model relates to a concentricity detector, which comprises a dial indicator and a mandrel. The dial indicator is fixed via a clamping device, the clamping device comprises a cross rod, a vertical rod, a slider and a slide groove, wherein one end of the cross rod is connected with a measuring rod of the dial indicator through a locking mechanism, the vertical rod is movably connected with the cross rod, the slider and the slide groove are placed correspondingly, the lower end of the vertical rod is connected to the slider, the mandrel is tubular and is fixed between a supporting object and a support through a locking screw, and the support and the supporting object are fixed onto a bottom plate. The concentricity detector is simple in structure, simple and convenient in use and low in production cost, is not high in requirements of work environments, and can be used for fast and accurately measuring products during mass production of the products.

Description

A kind of concentricity pick-up unit
Technical field
The utility model relates to a kind of concentricity pick-up unit.
Background technology
Add man-hour for machining pipe fitting such as powder metallurgy sleeve etc., the special-purpose concentricity meter of high precision is generally adopted in the detection of concentricity.Such detector can accurately detect the concentricity of institute's processing metal sleeve pipe, precision height, but this detector complex operation in use, itself costs an arm and a leg instrument, and working environment is had relatively high expectations, be not easy to fast carry out exactly in big the production measurement of product specification.
Summary of the invention
The utility model is for solving the problem in the above-mentioned technology, proposed a kind of easy and simple to handle, production cost is low and can fast carry out the concentricity pick-up unit that product is measured exactly big production.
Concentricity pick-up unit of the present utility model comprises dial gauge and plug, described dial gauge is fixed by a clamping device, described clamping device comprises cross bar, montant, slide block and chute, wherein, one end of cross bar is connected with the sounding rod of dial gauge by locking mechanism, montant and cross bar flexibly connect, the corresponding placement of slide block with chute, and the lower end of montant is connected to slide block; Described plug is the pipe shape and is fixed between stilt and the support by tie down screw that described support and stilt are fixed on the base plate.The axial line of the axial line of described plug and the measuring head of dial gauge is in same plane; The external diameter of described plug is less than the internal diameter of test product, and both differ and are no more than 0.1mm; Above support is an angle bar.
The utility model is simple in structure, and is easy to use, and production cost is low, less demanding and can carry out product more exactly in big production and measure to working environment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1, support; 2, dial gauge; 3, tie down screw; 4, cross bar; 5, montant; 6, slide block; 7, chute; 8, plug; 9, stilt; 10, base plate.
Embodiment
Embodiment 1
Below in conjunction with accompanying drawing the utility model is described.
As shown in the figure, concentricity pick-up unit of the present utility model, comprise dial gauge 2 and plug 8, dial gauge 2 is fixed by a clamping device, and clamping device comprises cross bar 4, montant 5, slide block 6 and chute 7, wherein, one end of cross bar 4 is connected by the sounding rod of locking mechanism with dial gauge 2, montant 5 flexibly connects with cross bar 4, slide block 6 and chute 7 corresponding placements, and the lower end of montant 5 is connected to slide block 6; Plug 8 is fixed between stilt 9 and the support 1 for the pipe shape and by tie down screw 3, and support 1 and stilt 9 are fixed on the base plate 10.Wherein the axial line of the measuring head of the axial line of plug 8 and dial gauge 2 is in same plane, and the external diameter of plug is less than the internal diameter of test product, and both differ and are no more than 0.1mm, and stilt 9 is an angle bar.
The utility model is used to measure the concentricity of hollow bushing such as powder metallurgy sleeve, during use, at first select a plug 8 that matches with the casing inner diameter size that will measure, use tie down screw 3 that plug 8 is fixed between angle bar and the support 1 then, the measured sleeve pipe box is gone into an end of plug 8, dial gauge is placed the top of sleeve pipe, the axial line of measuring head that makes the axial line of plug 8 and dial gauge 2 is in same plane, regulating cross bar 4 makes the measuring head of dial gauge 2 just contact the surface of tested sleeve pipe, the tested pipe fitting of hand rotation or push-and-pull, in this course of action, observe the beat of pointer situation of dial gauge 2, if beat of pointer scope surpasses the maximal value that allows, illustrate that then the concentricity of measured tube is undesirable; If beat of pointer scope then illustrates the concentricity requirement up to specification of measured tube less than the maximal value that allows.
