Abstract
The utility model discloses a fast detecting apparatus of straightness of a precision cold-rolled seamless steel pipe. An upper flat plate and a lower flat plate, which are oblique and parallel and have a certain distance between each other, are supported on support angle irons, wherein an entrance of the upper flat plate and the lower flat plate is connected with a material tray, an exit of the upper flat plate and the lower flat plate is connected with a material-holding area, and the certain distance between the upper flat plate and the lower flat plate equals to a maximum diameter of the steel pipe plus a maximum allowable error of the straightness of the steel pipe. A lower portion of a support rack is fixedly connected with a turnover vehicle. Through adopting the provided technical scheme of the fast detecting apparatus of straightness of a precision cold-rolled seamless steel pipe, efficiency is high and reliability is stable, and moreover, effect of using at any time and detecting at any time can be received, and problems such as low working efficiency, failure of eliminating non-qualified products completely and large labor intensity caused by detection methods in the prior art can be solved.
Description
Technical field
The utility model relates to a kind of accurate cold rolling seamless steel linearity device for fast detecting, belongs to linearity detection technique field.
Background technology
At present; The weldless steel tube of welding usefulness has strict requirement to linearity in the minicar transmission shaft, and in the car constant velocity cardan joint transmission shaft, tubular shaft is to be welded to form by two ends spindle nose and middle accurate cold rolling seamless hollow tubular; Locate two ends spindle nose car profile with the two ends center pit welding back; The intermediate hollow pipe is not processed, and in the bearing length range, external diameter is jumped the two ends center bore has strict demand; The degree of crook of finding hollow tubular in the actual process is the most remarkable to the footpath jumping influence of bearing opposite end center pit, therefore must the strict linearity of controlling hollow tubular.Prior art to the detection method of hollow tubular linearity is: hollow tubular is placed on two v blocks; One end leans against on the location-plate; Place three dial gauges that have the magnetic force dial framework simultaneously at the hollow tubular two ends and in the middle of the hollow tubular; Behind good table, rotate the reading that hollow tubular is seen three tables, which piece meter reading surpasses setting and all rejects.The disadvantage of this method is to measure the flexibility of any part of hollow tubular, and the relative measurement benchmark is two place's cylindricals, therefore can not unacceptable product 100% be chosen; Cause ultra-poor products to change next procedure over to, the influence assembling causes waste; Efficient is low simultaneously, and labour intensity is big.
Summary of the invention
The utility model technical matters to be solved is; A kind of accurate cold rolling seamless steel linearity device for fast detecting is provided; This device can overcome the shortcoming of existing detection technique, has realized that detection is quick, laborsaving, reliable, and the weldless steel tube qualification rate of use reaches 100%; Simultaneously can reduce labour intensity, boost productivity.
The technical scheme that the utility model provided is: accurate cold rolling seamless steel linearity device for fast detecting; It is characterized in that; Have the support angle bar, support the upper flat plate that is supported with inclinations, parallel, set a distance on the angle bar and dull and stereotyped down, the inlet of flat board is connected with care feed tray up and down; Dull and stereotyped up and down outlet is connected with the charge district, and the set a distance between said upper flat plate and following flat board is the maximum tolerance that the maximum gauge of steel pipe adds the steel pipe linearity.Supporting the angle bar bottom is fixedly connected with tote cart.
The technical scheme that the utility model provided detects the overproof problem of accurate cold rolling seamless hollow tubular linearity of tubular shaft center section for solving in the car constant velocity cardan joint transmission shaft.Through using this programme, can solve can not unacceptable product 100% being chosen that existing detection technique method caused, cause ultra-poor products to change next procedure over to, problem such as the influence assembling causes waste, and efficient is low simultaneously, and labour intensity is big.
Description of drawings
In conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the accurate cold rolling seamless steel linearity of the utility model device for fast detecting.
Fig. 2 be among Fig. 1 C to structural representation.
1 backgauge post, 2 swash plates, 3 upper flat plates, 4 nuts, 5 cylinder parallels, 6 times flat boards, 7 care feed trays, 8 support angle bar, 9 handles, 10 tote carts, 11 weldless steel tubes, 12 charge districts among the figure.
Embodiment
The accurate cold rolling seamless steel linearity of the utility model device for fast detecting; Supporting the upper flat plate 3 that is supported with inclinations, parallel, set a distance on the angle bar 8 and flat board 6 down; Dull and stereotyped up and down inlet is connected with care feed tray 7; Dull and stereotyped up and down outlet is connected with charge district 12, and front portion, charge district is provided with backgauge post 1, and the rear portion is provided with swash plate 2; The weldless steel tube 11 that the detection of straight lines degree is qualified is contained between backgauge post and the swash plate, and the set a distance between said upper flat plate and following flat board is the maximum tolerance that the maximum gauge of seized steel pipe adds the steel pipe linearity.Support the angle bar bottom and be fixedly connected with tote cart 10, tote cart 10 is provided with handle 9.Nut 4, cylinder parallels 5 are web members of upper and lower flat board among the figure.
According to the maximum linear degree of steel pipe maximum gauge and permission, confirm the relative position of two parallel plates, make distance between two parallel plates equal the maximum linear degree sum of steel pipe maximum gauge and permission.Parallel flat becomes certain pitch angle with surface level; In the self-locking scope, avoid skidding (adopting 7 degree) is if steel pipe is done pure rolling between two parallel planes; The overproof steel pipe of then every linearity is when doing pure rolling under the effect of its deadweight between two parallel planes; Its tactical diameter can not pass through two parallel planes greater than two plane distances, then rejects immediately; The not overproof steel pipe of every linearity is when doing pure rolling under the effect of its deadweight between two parallel planes, its tactical diameter is not more than distance between two parallel planes, can pass through two parallel planes smoothly, gets into the charge district.
Two parallel steel plates pass through the angle bar bolt on tote cart; The parallel steel plate porch is a care feed tray; Width is than the long 1mm of pipe material length, and pipe is expected to be placed on the care feed tray pure rolling again and descended, behind two parallel steel plates; Get into the charge district along swash plate, four round steel of front, charge district can prevent that the pipe material from falling earthward.All have alternate groove on the relative workplace of two parallel steel plates, can reduce the contact area of workpiece, be convenient to cleaning.Two parallel steel plate two ends must have groove (the dark 2mm of wide 5mm) simultaneously, and effect is that the flange burr that produces when making the blanking of steel pipe two ends moves in groove, can not run into two parallel steel plate workplaces, thereby avoid qualified part erroneous judgement to defective.Another benefit of using this device is part entrucking voluntarily after fast detecting, unnecessaryly is placed in again in the container car again, has saved the turnaround time, space and manpower.Two dull and stereotyped measuring instrument steel or the T10A tool steel of adopting about in the process, hardness HRC58-62 behind the Q-tempering should carry out Ageing Treatment, with anti-buckling deformation.(height tolerance≤0.005mm) is to guarantee the two dull and stereotyped depth of parallelisms for high property such as four cylindrical cushion blocks should guarantee.Should be coated with rust preventive oil in the use, avoiding getting rusty influences precision, should keep clean simultaneously.
