Description
Technical field
The utility model relates to a kind of Crankshaft Machining frock, particularly relates to a kind of clamping tool for machining crankshafts, belongs to mechanical manufacturing field.
Background technology
When the major axis of machining crankshafts, minor axis and crank exterior arc surface, outer face, need the major axis or the minor axis that clamp bent axle, it is inaccurate to there is location in the clamping tool adopted the processing of same kind of parts outer round surface at present, thus causes machining tolerance large, the problem that precision is low.Good fixture can ensure crudy, and the top priority of jig ensures machining accuracy, particularly ensures that workpiece to be machined is machined surface and locating surface and surface to be machined positional precision each other.Boost productivity, reduce costs, the utility model can reduce the non-cutting times such as line, centering, and is easy to realize multistation processing.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of clamping tool for machining crankshafts of a kind of easy and simple to handle, accurate positioning, stable and reliable operation.
The technical scheme in the invention for solving the above technical problem is: a kind of clamping tool for machining crankshafts, comprise pedestal, fixture block, spring and push rod, square cavity is provided with in described pedestal, cavity runs through two relative faces of pedestal, the both sides of cavity are respectively equipped with fixture block, clamping plate and pedestal adopt axis of rotation to be connected, described fixture block comprises chuck portion and root, chuck portion and root lay respectively at the two ends of fixture block, the root of described fixture block is provided with circular arc installation cavity, circular arc installation cavity is semi-closed structure, the arc surface of circular arc installation cavity is greater than the circular arc of hemicycle, round steel is provided with in circular arc installation cavity, push rod is located between the root of two fixture blocks, push rod comprises tapered portion and vertical bar portion, the tapered portion exterior surface round steel of push rod, vertical bar portion is located in cavity spacing by cavity, can only extend to movement along cavity, the root of two fixture blocks adopts spring to connect.
The utility model also comprises connecting plate, and connecting plate two ends penetrate rotating shaft and install.
Push rod described in the utility model is 40Cr material.
The utility model compared with prior art, has the following advantages and effect:
1, pedestal described in the utility model is structure as a whole, pedestal is as the main force part of pinching action, adopt integrative-structure intensity high, the root of fixture block is provided with round steel, round steel can rotate in installation cavity, round steel and push rod comprise tapered portion and contact rear rolling friction, there is frictional resistance little, push rod effect advantage flexibly, circular arc installation cavity is semi-closed structure, the arc surface of circular arc installation cavity is greater than the circular arc of hemicycle, and round steel only needs directly to insert in circular arc installation cavity, assembles fast easy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1, a kind of clamping tool for machining crankshafts described in the utility model, comprise pedestal 1, fixture block 2, spring 3 and push rod 4, square cavity 11 is provided with in described pedestal 1, cavity 11 runs through two relative faces of pedestal, the both sides of cavity 11 are respectively equipped with fixture block 2, clamping plate 2 and pedestal 1 adopt rotating shaft 5 to be rotationally connected, described fixture block 2 comprises chuck portion 21 and root 22, chuck portion 21 and root 22 lay respectively at the two ends of fixture block, chuck portion 21 is positions of clamping work pieces G, the root 22 of described fixture block 2 is provided with circular arc installation cavity 23, circular arc installation cavity 23 is semi-closed structure, namely the arc surface of circular arc installation cavity 23 is greater than the circular arc of hemicycle, round steel 6 is provided with in circular arc installation cavity 23, therefore round steel 6 is limited in circular arc installation cavity 23, can not shift out from the opening of circular arc installation cavity 23, push rod 4 is located between the root 22 of two fixture blocks 2, push rod 4 comprises tapered portion 41 and vertical bar portion 42, the tapered portion 41 exterior surface round steel 6 of push rod 4, vertical bar portion 42 is located in cavity 11 spacing by cavity 11, push rod 4 can only along the extension of cavity 11 to movement, the root 22 of two fixture blocks 2 adopts spring 3 to connect.
The utility model also comprises connecting plate 7, and connecting plate 7 two ends penetrate rotating shaft 5 and install.Connecting plate 7 plays booster action at this stress point of rotating shaft 5.
Push rod described in the utility model is 40Cr material.
Running, promote push rod 4 by hydraulic pressure or cylinder, push rod 4 is when moving to direction, chuck portion 21, tapered portion 41 contacts round steel 6, thus is closed up in two chuck portions 21, thus clamping work pieces G, after push rod 4 returns, fixture block 2 is by spring force effect, and workpiece G is unclamped in chuck portion 21.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
