Description
Technical field
The utility model relates to a kind of Crankshaft Machining Aided Machine, specifically a kind of crankshaft journal positioning clamping device.
Background technology
We know, need position clamping during crankshaft grinding to axle journal, if position during clamping is not fixed, the phenomenon that when easily causing axle journal grinding, circularity is not up to standard, and common detent mechanism, can only position by tolerance, there is certain error during clamping.Adopt the adjustable positioner of clamping force fundamentally can solve the unfixed problem of clamped position, get rid of error during clamping.But yet there are no the bibliographical information of the adjustable crankshaft journal positioning clamping device of clamping force up to now.
Summary of the invention
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, and provide a kind of simple and reasonable for structure, easy for operation, clamping and positioning is reliable, stable, the adjustable crankshaft journal positioning clamping device of clamping force.
The technical scheme in the invention for solving the above technical problem is: a kind of crankshaft journal positioning clamping device, it comprises locating piece, clamping bar, spring, adjusting nut, it is characterized in that: described locating piece is provided with a taper elongated slot being used for place work piece, locating piece side is provided with a cylinder shoulder hole communicated with taper elongated slot, and this cylinder shoulder hole rearward end is with internal thread; Described clamping bar is stepped cylindrical structure, and it is arranged in cylinder shoulder hole, front end and absorption surface, and on the cylinder of rear portion, cover has spring; Between the boss that described spring is provided with on adjusting nut and clamping bar; Described adjusting nut is provided with the external screw thread with locating piece screw-internal thread fit, rotates adjusting nut, and the decrement of adjustment spring, realizes the automatic adjustment of clamping bar to Workpiece clamping power.
Clamping bar front end described in the utility model is smooth ball head structure.
The utility model adopts above-mentioned composition structure, arranges the clamping bar of removable adjustment, position clamping to workpiece in the side of locating piece.Against existing technologies, the utility model is simple and reasonable for structure, easy for operation, and clamping and positioning is reliable, stable, and clamping force is adjustable, is a kind of desirable crankshaft journal positioning clamping device.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the structural representation of the utility model confined state.
Label in figure is: 1. locating piece, 2. clamping bar, 3. spring, 4. adjusting nut, 5. workpiece.
Detailed description of the invention
As can be seen from Figure 1, a kind of crankshaft journal positioning clamping device, it comprises locating piece 1, clamping bar 2, spring 3, adjusting nut 4, workpiece 5 etc.
Locating piece 1 top described in the utility model is provided with a taper elongated slot being used for place work piece, is convenient to workpiece 5 and puts into fast.Locating piece 1 side is provided with a cylinder shoulder hole communicated with taper elongated slot, and this cylinder shoulder hole rearward end is with internal thread.Described clamping bar 2 is stepped cylindrical structure, and it is arranged in cylinder shoulder hole, and front end contacts with workpiece 5, and on the cylinder of rear portion, cover has spring 3.Described spring 3 is regulating between the boss that spiral shell 4 mother and clamping bar 2 are provided with.Clamping bar 2 is moved around by spring 3 in cylinder shoulder hole, the guide effect that stepped cylindrical hole is risen.
Described adjusting nut 4 is provided with the external screw thread with locating piece 1 screw-internal thread fit, rotates adjusting nut 4, and the decrement of adjustment spring 3, realizes the automatic adjustment of clamping bar 2 pairs of workpiece 5 clamping forces, carry out clamping and positioning to workpiece.
Clamping bar 2 front end described in the utility model is smooth ball head structure.Like this, when workpiece 5 falls under gravity, the bulb that workpiece 5 is smooth with clamping bar 2 front end contacts, and move after extruding clamping bar 2, Compress Spring, does not hinder freely placing of workpiece.After freely falling, the bullet 3 of compression forces again clamping bar 2 pairs of workpiece 5 to implement location clamping.Rotate adjusting nut, the decrement of adjustment spring, and then realize the automatic adjustment of clamping bar to Workpiece clamping power.The cylinder of clamping bar rear end plays guide effect to spring.
The utility model adopts above-mentioned composition structure, arranges the clamping bar of removable adjustment, position clamping to workpiece in the side of locating piece.It is simple and reasonable for structure, easy for operation, and clamping and positioning is reliable, stable, and clamping force is adjustable, is a kind of desirable crankshaft journal positioning clamping device.
