Abstract
The utility model provides a continuous and automatic chain length measuring device, which can detect the length of a chain under the condition of continuous and automatic sliding of the chain, and solve the existing problems of low production efficiency of manual inspection, poor inspection precision and high expense. The continuous and automatic chain length measuring device comprises a fixed wheel arranged on a base, a movable pulley, two center distance adjusting wheels, and a chain wheel matched with the chain; axial lines of the wheels are parallel; a movable pulley shaft sleeved with the movable pulley is arranged on the base in a sliding manner; when the movable pulley shaft slides, the distance from the movable pulley shaft to a fixed wheel shaft can be changed; a counterweight is connected to the movable pulley shaft, and the counterweight leads the movable pulley shaft to be far away from the fixed wheel shaft in a normal state; the two center distance adjusting wheels are arranged at the upper part or lower part between the fixed wheel and the movable pulley; and the chain penetrates one center distance adjusting wheel, the fixed wheel, the movable pulley and the other center distance adjusting wheel in sequence.
Description
Technical field
The utility model relates to the continuously automatic measuring motion of chain, can be used for chain and surveys processes such as length, manufacturing, merogenesis, check.
Background technology
The chain check is generally and comprises the steps: prestretching, surveys long, merogenesis.Prestretching is after the chain assembling is finished, and gives the certain pulling force of chain to eliminate the fit-up gap.Survey length and be inspection chain overall length whether in the technical requirement scope, merogenesis is that the assembling rear chain is cut off by kind requirement joint number.Survey farm labourer's preface now by manually chain being carried out prestretching one by one, surveys length, production efficiency is low, and testing accuracy is poor, the labour cost height.
The utility model content
The purpose of this utility model provides the continuously automatic measuring motion of a kind of chain that can detect its length under the situation that chain flows to continuously and automatically, low to solve existing desk checking production efficiency, testing accuracy is poor, the problem that expense is high.
The continuously automatic measuring motion of this chain comprises fast pulley, movable pulley, two sprocket wheels that the centre distance adjustment is taken turns, cooperated with chain of being arranged on the base, parallel axes of above-mentioned each wheel; The slip wheel shaft of suit movable pulley is slidingly arranged on the base, when the slip wheel shaft slides, can change it and arrive the fixedly distance of wheel shaft; When being connected with on the slip wheel shaft, make the slip wheel shaft away from the fixing counterweight of wheel shaft in normality; Two centre distance adjustment wheel be arranged between fast pulley and the movable pulley above or below; Chain is successively by a centre distance adjustment wheel, fast pulley, movable pulley, another centre distance adjustment wheel.
During use, configuration forms the pulling force to chain, and this pulling force will be by the tension of the chain between the tight and loose pulley, so the distance between the tight and loose pulley reflects the chain length between the tight and loose pulley indirectly.When chain passes through tight and loose pulley automatically, the slip wheel shaft has reflected the chain length mobility scale of certain chain link with respect to the fixing position range of wheel shaft, that is to say, if the position range of slip wheel shaft is in certain amplitude range the time, chain length is promptly in the scope that requires and not overproof; If the position range of slip wheel shaft surpasses in certain amplitude range, illustrate that chain length is overproof.Therefore the utility model can detect its length under the situation that chain flows to continuously and automatically, the efficient height, and the precision height, labour cost is low.
As improvement to the continuously automatic measuring motion of above-mentioned chain, it also comprises two angle sheaves that contact with chain, two centre distance adjustment wheel and two angle sheaves are arranged on the periphery of sprocket wheel, the part of chain a centre distance adjustment take turns and the effect of an angle sheave under mesh with sprocket wheel one side; Another part of chain meshes with the sprocket wheel opposite side under the effect of another centre distance adjustment wheel and another angle sheave.Like this, the sprocket wheel by a rotation can drive flowing to of chain simultaneously and flow out simple and ingenious structure.
As to the improvement of measuring motion automatically continuously of above-mentioned chain, between slip wheel shaft and counterweight, be connected with pull pressure sensor.Can see the pulling force of counterweight immediately by pull pressure sensor to chain.
Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Referring to chain shown in Figure 1 continuously automatically measuring motion comprise the fast pulley 1 that is arranged on the base, movable pulley 2, two 3, two angle sheaves 4 of centre distance adjustment wheel, the sprocket wheel 5 that cooperates with chain, sprocket wheel 5 is connected with its rotating mechanism of drive.The parallel axes of above-mentioned each wheel.Two centre distance adjustment wheels 3 are arranged on the both sides, top of sprocket wheel, and two angle sheaves 4 are arranged on the both sides, top of sprocket wheel.6 parts (section of flowing to) of chain mesh with sprocket wheel 5 left sides under the effect of an angle sheave in centre distance adjustment wheel in left side and left side; Another part of chain 6 (flowing out section) meshes with sprocket wheel 5 right sides under the effect of an angle sheave of right side centre distance adjustment wheel and right side.The slip wheel shaft 7 of suit movable pulley 2 is slidingly arranged on the base, when the slip wheel shaft slides, can change it and arrive the fixedly distance of wheel shaft.When being connected with on the slip wheel shaft 7, make the slip wheel shaft away from the fixing counterweight 8 of wheel shaft in normality; Between slip wheel shaft and counterweight, be connected with pull pressure sensor 9.The plane parallel at 3 axis places is taken turns in the plane at fast pulley 1 axis and movable pulley 2 axis places and two centre distance adjustment, and tangent line also is simultaneously a tangent line outside the top of two centre distance adjustment wheels 3 outside fast pulley 1 and movable pulley 2 bottoms.Chain flows to from the angle sheave 4 in left side, more successively by sprocket wheel 5 left sides, left side centre distance adjustment wheel, fast pulley 1, movable pulley 2, the centre distance adjustment wheel on right side, sprocket wheel 5 right sides, after right hand guide wheels 4 outflows.
Claims (3)
1. the continuous automatically measuring motion of chain is characterized in that: it comprises the fast pulley that is arranged on the base, movable pulley, two centre distance adjustment wheels, the sprocket wheels that cooperate with chain, above-mentioned parallel axes of respectively taking turns; The slip wheel shaft of suit movable pulley is slidingly arranged on the base, when the slip wheel shaft slides, can change it and arrive the fixedly distance of wheel shaft; When being connected with on the slip wheel shaft, make the slip wheel shaft away from the fixing counterweight of wheel shaft in normality; Two centre distance adjustment wheel be arranged between fast pulley and the movable pulley above or below; Chain is successively by a centre distance adjustment wheel, fast pulley, movable pulley, another centre distance adjustment wheel.
