Description
Technical field
This utility model relates to the technical field of lathe copying device, is specifically related to the profiling clamping device of a kind of automobile crane.
Background technology
Bent axle is as the term suggests it is an axle, and axle is bending.Automobile crane is most important parts in electromotor.It bears the power that connecting rod transmits, and is transformed into torque and is exported by bent axle and drive other adnexaes work on electromotor.
Because bent axle has multiple flex point, and not along axisymmetrical, therefore the geometric center of bent axle is not on axis.When laterally disposed for bent axle on a certain plane and not bent axle is not applied external force time, because the contact surface of bent axle Yu plane is less, bent axle is susceptible to rotation, and position heavier on bent axle can go to lowest point under gravity.
In order to make bent axle clamp by required angle, it is necessary to arrange the workbench contacted with bent axle curved surface according to the laying state needed for bent axle.Such a workbench may be only available for some laying state of bent axle, and this versatility allowing for workbench is not strong.
Utility model content
This utility model provides a kind of automobile crane positioner, may be only available for some laying state of bent axle, the problem that versatility is not strong with the workbench solving to contact with automobile crane.
nullIn order to solve above-mentioned technical problem，This utility model provides following technical scheme: a kind of automobile crane positioner，Including base and clamping device，Clamping device is located on base，Also include stage clip and the baffle plate being arranged on base，Base has stopper slot，Several locating pieces are had in stopper slot，The length of locating piece is mated with the width of stopper slot，The height of locating piece mates with the degree of depth of stopper slot，The length direction of locating piece is parallel with the width of stopper slot，It is connected by stage clip between bottom surface and the bottom surface of locating piece of stopper slot，The initial length of stage clip is more than 2 centimetres，The coefficient of elasticity of stage clip is less than 0.5N/mm，Baffle plate is positioned at a long side of stopper slot，Described clamping device includes pole、Cylinder and push rod，Pole is connected with base，Cylinder is connected on pole，Push rod is slidably connected in cylinder，One end of push rod is towards baffle plate，The side of cylinder has through hole，Fastening bolt it is installed with in through hole.
In this article, the one of stopper slot long side refers to the one side of stopper slot length direction.
The principle of this programme: during operation, is placed on locating piece by bent axle, and the axis direction of bent axle is consistent with the length direction of locating piece, the shape according to bent axle, and locating piece can sink therewith, with the mating shapes of bent axle.The curved surface of bent axle also can contact with baffle plate, is finally located by clamping device.
Compared with prior art, the utility model has the advantage of: 1, be provided with locating piece in the stopper slot of base, the bottom surface of locating piece is provided with initial length more than 2 centimetres, the coefficient of elasticity stage clip less than 0.5N/mm.The locating piece contacted with bent axle can sink according to the bent axle shape being in contact with it.2, the two of stopper slot long sides are provided with baffle plate and push rod, and being placed on the bent axle on locating piece can contact with baffle plate simultaneously.Push rod can slide along cylinder, and when push rod contacts with automobile crane, available fastening bolt is located, thus realizing when bent axle is in required laying state, bent axle being clamped.This utility model increases the contact area between bent axle and clamping device, and bent axle, under the constraint of locating piece and baffle plate, is not susceptible to rotate, it is adaptable to the multiple laying state of different bent axles, versatility is stronger.
Further, the distance of described baffle plate and locating piece less than 1 centimetre, the close together of baffle plate and locating piece, it is ensured that no matter the bent axle being positioned on locating piece with which kind of angle is placed, all can contact with baffle plate.
Further, the width of described locating piece is that 5 millimeters of points that can guarantee that locating piece contacts with bent axle are more, makes the sinking of locating piece and the shape of bent axle more fit.
Further, described baffle plate is provided with rubber layer towards the one side of location-plate, adds the coefficient of friction between bent axle and baffle plate.
Further, described push rod is provided with magnetosphere towards the end face of baffle plate, and because automobile crane is magnetic metal, therefore the end face of push rod can be close to automobile crane under the effect of magnetic force.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of this utility model automobile crane positioner embodiment.
Fig. 2 is the structural representation of this utility model automobile crane clamping device stopper slot embodiment.
Detailed description of the invention
Accompanying drawing labelling in Figure of description includes: base 1, stage clip 2, stopper slot 3, locating piece 4, baffle plate 5, cylinder 6, push rod 7, fastening bolt 8.
As it is shown in figure 1, a kind of automobile crane clamping device in the present embodiment, it is installed on base 1 including base 1, stage clip 2, baffle plate 5 and clamping device, clamping device and baffle plate 5.
As in figure 2 it is shown, have stopper slot 3 on base 11, the length of stopper slot 3 is 20 centimetres, and width is 10 centimetres, and the degree of depth is 8 centimetres.Having 40 locating pieces 4 in stopper slot 3, the length of locating piece 4 is 10 centimetres, and width is 5 millimeters, is highly 8 centimetres.When placing, the length direction of locating piece 4 is parallel with the width of stopper slot 3.Being connected by stage clip 2 between the bottom surface of stopper slot 3 and the bottom surface of locating piece 4, the initial length of stage clip 2 is 2 centimetres, and the coefficient of elasticity of stage clip 2 is less than 0.4N/mm.
Baffle plate 5 is positioned at the side of stopper slot 3, and baffle plate 5 is provided with rubber layer towards the one side of locating piece 4, and clamping device is positioned at the opposite side of stopper slot 3.Clamping device includes pole, cylinder 6 and push rod 7, and pole is connected with base 1, and cylinder 6 is connected on pole, and push rod 7 is slidably connected in cylinder 6.One end of push rod 7 is towards baffle plate 5, and push rod 7 is provided with magnetosphere towards the end face of baffle plate 5.The side of cylinder 6 has through hole, is installed with fastening bolt 8 in through hole.
In the present embodiment, during operation, automobile crane is placed on locating piece 4 by required angle, and makes the curved surface of automobile crane contact with the rubber layer of baffle plate 5.It is to be noted that the axis direction of bent axle is consistent with the length direction of locating piece 4.Because the bottom surface of locating piece 4 is provided with comparatively sensitive spring, locating piece 4 is subject to again the restriction of stopper slot 3 and will not move in the horizontal direction, therefore 4 meetings of locating piece are sunk according to the shape of the automobile crane touched, the curved surface of automobile contacts with baffle plate 5 again simultaneously, on condition that an external force is not applied, automobile crane is without rotating, it is prevented that position heavier on bent axle can go to lowest point under gravity.Then unscrewing fastening bolt 8, released by push rod 7 in cylinder 6, push rod 7 can move closer to automobile crane, and under the effect of magnetic force, push rod 7 can fit tightly with automobile crane.Finally screw fastening bolt 8, automobile crane is correctly positioned.
For a person skilled in the art; under the premise without departing from this utility model structure; can also making some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.
