The utility model solves the problem of fast and reliably detecting minor axis (the pin roll of the chain is unqualified) so as to carry out correction in time. The measuring instrument is simple in structure, easy for processing, low in cost and high in reliability with practicability.
Description
Technical field
The utility model relates to the part processing field, specifically is a kind of detector of chain hinge pin length of the detection that is used for chain hinge pin length.
Background technology
In automation process, the bearing pin blanking of chains such as bicycle, motorcycle is by specialized equipment high speed bearing pin blanker blanking.Though this kind processing mode efficient is higher, can produce the minor axis phenomenon because of feeding is unstable, the way that adopts is with the outer diopter artificial visually examine sorting of bearing pin at present, but following deficiency is arranged: efficient is low, and the visual inspection of personnel selection method is adopted a large amount of artificial, increases production cost; Precision is low, and bearing pin length can sort out when having only error big, and error hour artificial visually examine can't be differentiated; Reliability is low, and the artificial visually examine can not guarantee 100% pinpoint the problems because of human factor.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of device of special inspection chain hinge pin length, concrete technical scheme is as follows:
A kind of detector of chain hinge pin length comprises depression bar, base, and depression bar and base flexibly connect, and constitutes lever construction, and depression bar and base junction are the fulcrum of lever construction; Be provided with locating slot on base, the width of locating slot opening is not less than the width of tested chain; Be provided with measuring head on depression bar, measuring head is corresponding with the position of locating slot; Also be provided with feeler lever on the depression bar, also be provided with contact with the feeler lever correspondence position.
The length of described measuring head is 1.1～1.5 times of chain pitch.
Described depression bar is provided with elastic device.(make this detector under the situation that is not subjected to other external force, depression bar is in pressed status.)
Described depression bar and base junction are provided with rotation axis.Described elastic device is the torsion spring that is provided with on rotation axis; One end of described torsion spring connects depression bar, and the other end connects base.
Described elastic device also can be the extension spring that is provided with on depression bar, and an end of described extension spring connects depression bar, and the other end is located at the fixed position outside the depression bar.
As improvement, the width of measuring head is not more than the width of locating slot; During measurement, measuring head is in locating slot.In locating slot, the corresponding measuring head that also is provided with down with measuring head.The effect of following measuring head is to hold up chain, guarantees the length of a bearing pin of measuring head while contact measurement up and down.
Described contact is a microswitch.
By analysis, bearing pin can not have the overlength phenomenon because of the principle of work decision of blanker only minor axis might take place.As long as this device is the minor axis in the discovery chaining.
The utility model has solved fast, finds the minor axis (chain hinge pin is defective) in the chaining reliably, so that the problem of timely finishing.This surveying instrument is simple in structure, and practicality is easy to processing, and cost is low, the reliability height.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
A kind of detector of chain hinge pin length comprises depression bar, base, and depression bar and base flexibly connect, and constitutes lever construction, and depression bar and base junction are the fulcrum of lever construction; Be provided with locating slot on base, the width of locating slot opening is not less than the width of tested chain; Be provided with measuring head on depression bar, measuring head is corresponding with the position of locating slot; Also be provided with feeler lever on the depression bar, also be provided with contact with the feeler lever correspondence position.Described contact is a microswitch.
The length of described measuring head is 1.1～1.5 times of chain pitch.Extension spring is set on depression bar, and an end of extension spring connects depression bar, and the other end is located at the fixed position outside the depression bar, makes depression bar stressed downwards.
The width of measuring head is not more than the width of locating slot; During measurement, measuring head is in locating slot.In locating slot, the corresponding measuring head that also is provided with down with measuring head.
In this example, feeler lever uses screw.Screw is installed in the rear portion of depression bar, passes depression bar, fixes with nut.Described microswitch connects switch or other electrical equipment of control traction electric machine.
Also be provided with limit for height in this example and survey axle bed, locating slot is located in limit for height is surveyed axle bed, as the passage of tested chain.This also plays limit for height and surveys the axle bed pedestal effect of measuring head and depression bar up and down.
As Fig. 3, during measurement, chain is the suitable channel flow of checking under traction is used under the effect of traction electric machine.Measuring head is in locating slot, and the width of measuring head is not more than the width of locating slot.Chain stands in the locating slot on the base, chain hinge pin axially identical with the opening direction of locating slot.Chain hinge pin is clipped between measuring head and the following measuring head.
Chain is checked channel flow in the traction lower edge of traction electric machine, measures bearing pin length through measuring head and following gauge head.Measuring head length is that 1.1P～1.5P (P is a chain pitch) guarantees have a bearing pin to be measured length separately when surveying inspection, and can not slip between adjacent two bearing pins and be stuck (as Fig. 3).When short pin shaft passed through measuring head, measuring head and feeler lever moved down under the extension spring effect, touched microswitch, then shut down.
Relation between bearing pin length and the feeler lever displacement is amplified by lever principle, for example, when bearing pin length weak point 0.01mm, feeler lever displacement 0.05mm (amplifying 5 times).Halt switch contact (being microswitch) can be appointed the length of regulating tested bearing pin.
The inspection method of this detector is, when by chain minor axis being arranged, utilizes lever principle displacement enlargement feeler lever variable quantity, reaches the purpose of accurate judgement.
