Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Fig. 1 is the structural representation of the keyseat frock that the utility model embodiment one provides, Fig. 2 is the structural representation of base in Fig. 1, Fig. 3 is the left view of Fig. 2, Fig. 4 is the structural representation of back-up block in Fig. 1, Fig. 5 is that sectional view is looked on a left side of Fig. 4, Fig. 6 is the structural representation of Fig. 1 middle guide, Fig. 7 is the top view of Fig. 6, Fig. 8 is the structural representation of the second clamp in Fig. 1, Fig. 9 be guide rail with the first clamp coordinate schematic diagram, for convenience of explanation, the part relevant to the utility model is only gived in figure.

The keyseat frock that the utility model provides, comprise base 1, base 1 is provided with the first chute 2 and the second chute 3, first chute 2 and the second chute 3 arrange on the same line, first chute 2 and the second chute 3 are concave slot, the first tailstock 4 is slidably fitted with in first chute 2, the second tailstock 5 is slidably fitted with in second chute 3, first tailstock 4 is provided with first top 6 near one end of the second tailstock 5, second tailstock 5 be provided with near one end of the first tailstock 46 positions top with first corresponding second top 7, base 1 is also provided with two guide rails 8, two guide rails 8 be arranged in parallel and between the first tailstock 4 and the second tailstock 5, the bearing of trend of guide rail 8 and the bearing of trend of the first chute 2 perpendicular, two guide rails 8 are slidably fitted with the first clamp 9 and the second clamp 10, first clamp 9 is provided with the first installing hole, in first installing hole, screw is installed, second clamp 10 is provided with second installing hole corresponding with the first position of mounting hole, first clamp 9 is connected leading screw 11 respectively by screw with the second installing hole with the second clamp 10, leading screw 11 extends back-up block 12 away from one end of the second clamp 10, back-up block 12 is fixedly mounted on base 1.

Guide rail 8 comprises on fixed part 81 and guide part 82, first clamp 9 and the second clamp 10 and is equipped with the breach suitable with guide part 82 shape, and guide part 82 is arranged in breach.

Its using method is:

First regulate the distance between the first tailstock 4 and the second tailstock 5, make to be arranged on first top 6 on the first tailstock 4 and to be arranged on second top 7 on the second tailstock 5 camshaft is held out against, rotational lead screw 11 again, first the rotation of leading screw 11 can drive the second clamp 10 to move to the direction near back-up block 12, until the second clamp 10 touches camshaft, being rotated further leading screw 11 can allow the first clamp 9 move to the direction away from back-up block 12, until the first clamp 9 touches camshaft, camshaft clamps by the first clamp 9 and the second clamp 10, can ensure that camshaft can not rotate in the process of keyseat, ensure the machining accuracy of keyway, keyway symmetry is high.
