Abstract
The utility model relates to a crankshaft testing bracket positioning device, which comprises a limiting plate, a pin sleeve, a positioning pin and a stop rod, wherein a rotatable shaft of the testing bracket is fixed to the limiting plate, the testing bracket rotates around the rotatable shaft, the pin sleeve is fixed to the rotatable testing bracket, the positioning pin is arranged inside the pin sleeve, the positioning pin controlled by a handle on the upper portion of the positioning pin and the stop rod can controllably insert into or depart from positioning round holes on the limiting plate. When the stop rod is positioned inside a long groove on the end portion of the pin sleeve, the positioning pin can be inserted into the holes of the limiting plate, thereby preventing the crankshaft testing bracket from rotating. Besides, when the stop rod stretches across the long groove on the end portion of the pin sleeve, the positioning pin completely shrinks back inside the pin sleeve, thereby the limiting device is under departing condition and the crankshaft can rotate freely around the rotatable shaft. The utility model has the advantages of simple structure and convenient usage, which can not only enable the testing bracket to rotate around the rotatable shaft of the bracket, but also enable the same to be positioned reliably. Moreover, the bracket can rotate around the rotatable shaft and depart and combine conveniently.
Description
Technical field
The utility model relates to a kind of locating device, specifically a kind of positioning device for crankshaft checking bracket
Background technology
We know that the check of bent axle quality generally is supported on bent axle on the crankshaft checking bracket to be carried out.When carrying out visual testing, require bent axle together with support, rotate around the rotating shaft of support.But when dimensional measurement, then require bent axle and support to maintain static.Up to now, also there is not special-purpose positioning device for crankshaft checking bracket.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to use, in the checkout procedure, checking bracket is rotated around the rotating shaft of support, checking bracket is reliably located, and support rotates around the axis and separates and in conjunction with positioning device for crankshaft checking bracket easily.
The technical scheme in the invention for solving the above technical problem is: a kind of positioning device for crankshaft checking bracket, it is characterized in that: it includes limiting plate, guide, register pin, arresting lever, said limiting plate maintains static, the rotating shaft of checking bracket is fixed on the limiting plate, checking bracket rotates around the shaft, guide is fixed on the rotatable checking bracket, register pin is installed in the guide, register pin is subjected to the control of its upper handle and arresting lever, controllably inserts or leave the positioning round orifice on the limiting plate.
The said guide of the utility model is the right cylinder with stepped appearance endoporus, and the diametric(al) of its aperture end, top has an elongated slot that connects.Said register pin is the little axle of a ladder, and its large-diameter portion divides and cooperates with the large-diameter portion subdivided gap of guide endoporus, and outer cover is equipped with a spring, and the diameter circular hole identical with arresting lever bored at register pin path position, and arresting lever is installed in this circular hole.During assembling spring, register pin are installed in the guide successively, and make the path part of register pin, pass the aperture of guide, and make the circular hole at register pin path position expose the end face of guide, and arresting lever is installed in circular hole.
The locating device that the utility model assembles is installed on the crankshaft checking bracket of rotation.During work, mention and the rotational positioning pin by handle, when in the elongated slot that arresting lever is placed the guide end, register pin is under the effect of spring, and its large-diameter portion branch stretches out the guide outside, insert in the hole of limiting plate, thus the rotation of restriction crankshaft checking bracket; When with arresting lever across on the elongated slot of guide end the time, spring is compressed, register pin large-diameter portion branch will leave limiting plate, all be withdrawn into the guide the inside, stop means is in released state, crankshaft checking bracket can freely rotate around the shaft.Against existing technologies, the utility model is simple in structure, and is easy to use, in the checkout procedure, checking bracket rotated around the rotating shaft of support, and checking bracket is reliably located, and support rotates around the axis and separates and the combination convenience.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cross section view of Fig. 1.
1. guidees among the figure, 2. spring, 3. register pin, 4. handle, 5. arresting lever, 6. plain cushion, 7. checking bracket, 8. round nut, 9. limiting plate, 10. rotating shaft.
Embodiment
As shown in Figure 1 and Figure 2, a kind of positioning device for crankshaft checking bracket is made up of guide 1, spring 2, register pin 3, handle 4, arresting lever 5, plain cushion 6, round nut 8, limiting plate 9.Limiting plate 9 is fixed.Rotating shaft 10 is fixed on the limiting plate 9.Guide 1 is fixed on the rotatable crankshaft checking bracket 7 by round nut 8, makes this locating device with crankshaft checking bracket 7 10 rotations around the shaft.
The said guide 1 of the utility model is the right cylinder with stepped appearance endoporus, and the diametric(al) of its aperture end, top has an elongated slot that connects.The degree of depth of elongated slot equals the stroke of register pin, and width is slightly larger than the diameter of arresting lever.Spring 2, plain cushion 6, register pin 3 are installed in the guide 1, and register pin 3 can slide in guide 1.
Said register pin 3 is the little axles of a ladder, and its large-diameter portion divides and cooperates with the large-diameter portion subdivided gap of guide 1 endoporus, and outer cover is equipped with a spring 2.The diameter of register pin 3 path part undersized shoulder hole aperture in guide 1.In the big footpath of register pin 3 distance approximately with the path position at guide 1 equal altitudes place, bore the identical circular hole of a diameter and arresting lever 5, arresting lever is installed in this circular hole.During assembling spring, register pin are installed in the guide successively, and make the path part of register pin, pass the aperture of locating sleeve, and make the circular hole at register pin path position expose the end face of guide, and arresting lever is installed in circular hole.Register pin 3 is subjected to the restriction of arresting lever 5 can not break away from guide 1.When mentioning and turning handle 4, when making the elongated slot on the arresting lever 5 aligning guidees 1, register pin 3 moves down under the effect of spring 2, and guide 2 is ejected in the end, and is inserted in the circular hole of limiting plate 9, and restriction crankshaft checking bracket 7 is around the rotation of axle 10.When mentioning and rotary handle 4 makes arresting lever 5 across on the elongated slot of guide 1 end the time, register pin 3 leaves limiting plate 9, all is withdrawn into the guide the inside, and stop means is in released state, and bent axle support 7 can 10 freely rotate around the shaft.The utility model is simple in structure, separates, in conjunction with efficient and convenient, and is very practical.
