Abstract

The utility model discloses a detection device applied to circle run-out of drill blank bars. The detection device comprises a dial indicator, a V-shaped detection platform, a square groove, a deflector rod and a deflector rod support, wherein the V-shaped detection platform is composed of two groups of four steady bearing idler wheels and one manual-operated bearing idler wheel, the steady bearing idler wheels are arranged on the square groove, the manual-operated bearing idler wheel is arranged on the deflector rod, and the deflector rod is arranged on the deflector rod support. The manual-operated bearing idler wheel is located on the steady bearing idler wheels, and the wheel diameter of the manual-operated bearing idler wheel is greater than that of each steady bearing idler wheel. According to the detection device, two groups of support structures formed by the four bearing idler wheels and the manual-operated bearing idler wheel structure driving bars to rotate are used to replace a common V-shaped groove at present, and therefore not only is labor saved but also the bars are enabled to rotate at uniform velocity, and rolling measurement of the bars is facilitated. The detection device is simple in structure, low in manufacturing cost, simple and convenient to operate, suitable for testing of products of hard alloy micro-drill bars, and capable of greatly improving detection precision and work efficiency and lowering labor intensity of workers.

Description

Hair bear grudge for drill rod runout detection device

Technical field

The utility model relates to a hair bear grudge for drill rod runout detection device.

Background technology

Detect at present after the centerless grinding shape errors such as the circle of bar is beated, circularity, two kinds of detection meanss are arranged: the one, bar is placed on detects with feeler gauge with the rolling of hand propelled bar on the grouan platform; The 2nd, bar is placed in the V groove, the moving bar rotation of hand-screw (also useful motor-driven) adopts clock gauge to detect round beating.Above detection method is applicable to and detects diameter and the bigger bar of length; And to the little brill bar about diameter phi 3.25mm length 40mm; Not only labour intensity is big, efficient is low for above detection method, and depends on the experience of quality inspection personnel, and the testing result error is bigger than normal; Detection difficulty is very big, can not be used for the detection that little brill bar circle is beated reliably, efficiently.

The utility model content

The purpose of the utility model is to provide a kind of portable detector that little brill bar circle is beated that is used for detecting.

The utility model provides this applies to drill rod runout hairy bear grudge detection devices, including dial gauge, supported by two four roller bearings, roller bearings consisting of a manual V-detection platform, installation support bearing rollers square tank, installation manual lever roller bearings, mounted lever of the lever bracket; manual roller bearings located above the support bearing rollers, manual roller bearing wheel diameter greater than the diameter of a wheel support bearing rollers.

The height of said driving lever support is greater than the height of said square groove.

One end of said driving lever has the vertical notch with said manual bearing roller coupling, and the other end bottom of driving lever is connected with back-moving spring.

Said clock gauge is positioned at a side of said driving lever, is connected with the dial plate anchor clamps, and the dial plate anchor clamps are connected with the connection support, and the bottom that connects support connects a base plate.

The lower end of said square groove, driving lever support, back-moving spring is fixed on the said base plate; The centerline collineation of three on base plate; Square groove is positioned at the other end heteropleural that connects support on the base plate, and back-moving spring and driving lever support are successively between said connection support and square groove.

The utility model uses two groups of four bearing rollers supporting construction of forming and the manual bearing roller structure replacement V-type groove commonly used at present that drives the bar rotation, and is not only laborsaving but also bar is at the uniform velocity rotated, and helps the bar tolling measurement.This apparatus structure is simple, and cost of manufacture is low, and is easy and simple to handle, is applicable to that the product of the little brill bar of wimet detects, and can greatly improve accuracy of detection and work efficiency, reduces working strength of workers.

Embodiment

Figures 1 to 5, the invention provides such a suitable drill rod runout wool bear grudge detection apparatus includes a base plate 1, the lever 2, the indicator 3, the lever holder 4, the indicator contacts 5, 6 manually roller bearing, bracket 7, the support bearing rollers 8, Table 9, Block, square groove 10, the dial clamp 11, the return spring 12, the dial 13.The height of driving lever support 4 is greater than the height of square groove 10, and clock gauge 3 comprises dial plate 13, gauge stand 9, measuring contacts 5.One end of driving lever 2 has the vertical notch with manual bearing roller 6 couplings.

Installation process is following: on base plate 1, offer five positioning spiro pits, respectively as shown position fixedly square groove 10, driving lever support 4, connect support 7, back-moving spring 12.The upper end that connects support 7 is connected dial plate anchor clamps 11, and the other end of dial plate anchor clamps 11 is connected with the gauge stand 9 of clock gauge 3.The upper end, the other end that have an end of notch to be installed on driving lever support 4 driving lever 2 are connected with back-moving spring 12; Spring bearing roller 8 is vertically connected in the upper end notch of square groove 10; Manually bearing roller 6 is vertically connected in the notch on the driving lever 2; Spring bearing roller 8 has two groups, is arranged in parallel, and the longitudinal center line that guarantees manual bearing roller 6 is the axial symmetrical center line of two groups of spring bearing rollers 8.

Specific operation process is following: press this end that driving lever 2 leans on back-moving spring 12 with hand; Driving lever 2 rotates around the tie point of itself and driving lever support 4; Manually bearing roller 6 is inclined upwardly to move thereupon and opens, and product to be measured is lain on the support roller 8, unclamps driving lever 2; Under the effect of back-moving spring 12, manually bearing roller 6 compresses product to be measured automatically.Two groups of spring bearing rollers parallel to each other 8 steadily grasp product to be checked with manual bearing roller 6; Gauge stand 9 extends to the roller place with the contact 5 of clock gauge 3; Adjustment form plate clamp 11 guarantees that clock gauge contact 5 contacts with the face of cylinder of product to be measured; Stir manual bearing roller 6, product to be checked and spring bearing roller 8 will be driven together and rolled.Be readablely on the dial plate 13 of 0.001mm clock gauge 3 must justify the numerical value of beating in precision.

The utility model is particularly suitable for printed circuit board micro drill rod that is slightly hairy bear grudge drill rod runout mechanical testing.
