Description
Technical field
The utility model relates to a kind of anchor clamps, specifically, relates to a kind of flywheel dynamic balance running anchor clamps.
Background technology
Flywheel after finishing making, install before, need carry out dynamic balance running to it, whether up to standard with the quality of check flywheel.Generally, when flywheel is carried out dynamic balance running, be to adopt straight pin that flywheel is positioned on the dynamic balance running worktable.Owing to have tolerance clearance between the dead eye of straight pin and flywheel, influence the precision of the dynamic balance running of flywheel.
Summary of the invention
The purpose of this utility model provides a kind of flywheel dynamic balance running anchor clamps that improve flywheel dynamic balance running precision.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of flywheel dynamic balance running anchor clamps is characterized in that: this test fixture comprises clamp body, spacing collar, elastic body, centration axis, blocks a shot and is fixed on the dish that connects of clamp body bottom; Clamp body is the solid of revolution of hollow, and the inwall at middle part is provided with internal thread, and the lateral wall on top is the conical surface; Spacing collar is socketed on the clamp body, and is fixed on the outward extending step of outer wall at clamp body middle part; Spacing collar is provided with a power transmission pin and a nail, and the power transmission pin is plugged in the spacing collar downwards and fixes, and a nail lower end is fixed on the spacing collar; Elastic body is " ∏ " shape, and its top is socketed on the centration axis, and the bottom is stuck in the top of clamp body; The madial wall of elastic body bottom is and the corresponding conical surface of the lateral wall on clamp body top; Block is located at elastomeric top, and the upper end that is socketed in centration axis is also fixing; The lower end of centration axis is threaded on the middle part inwall of clamp body.
The bottom of described power transmission pin is fixed in the spacing collar by tight fixed bolt.
Described block is fixed on the centration axis by taper bolt.
Owing to adopted above-mentioned technical scheme, compare with traditional straight pin locator meams, flywheel is assemblied in the enterprising action balance test of the utility model, can improve flywheel dynamic balance running precision.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of anchor clamps among the embodiment of the present utility model;
Fig. 2 is the assembling synoptic diagram of anchor clamps described in the embodiment of the present utility model and flywheel.
Embodiment
Embodiment: a kind of flywheel dynamic balance running anchor clamps as shown in Figure 1, comprise clamp body 4, spacing collar 5, elastic body 8, centration axis 9, block 10 and are fixed on connecing of clamp body 4 bottoms by screw 3 and coil 2.Clamp body 4 is the solid of revolution of hollow, and the inwall at middle part is provided with internal thread, and the lateral wall on top is the conical surface.Spacing collar 5 is socketed on the clamp body 4, and is fixed on by screw 13 on the outward extending step of outer wall at clamp body 4 middle parts; Spacing collar 5 is provided with a power transmission pin 7 and a nail 12, and the bottom of power transmission pin 7 is plugged on downwards in the spacing collar 5, and fixing by tight fixed bolt 6.Propping up nail 12 lower ends is fixed on the spacing collar 5.Elastic body 8 is " ∏ " shape, and its top is socketed on the centration axis 9, and the bottom is stuck in the top of clamp body 4; The madial wall of elastic body 8 bottoms is the corresponding conical surface of lateral wall with clamp body 4 tops.Block 10 is located at the top of elastic body 8, is socketed in the upper end of centration axis 9, and fixing by taper bolt 11.The lower end of centration axis 9 is threaded on the middle part inwall of clamp body 4.
When flywheel is carried out dynamic balance running, by screw 1 above-mentioned test fixture is installed on the dynamic balance running worktable earlier, then flywheel 14 is assemblied on the test fixture.Fit as shown in Figure 2, the dead eye of flywheel 14 is enclosed within on the elastic body 8, power transmission pin 7 correspondences are inserted in the pilot hole of flywheel 14,12 pairs of flywheels 14 of nail play a supportive role.Then, rotate centration axis 9, because clamp body 4 is fixed, centration axis 9 moves down, and block 10 promotes elastic body 8 and moves down, when elastic body 8 moves down, and the dead eye of the outside tensioner flywheel 14 of meeting, thus flywheel 12 is fixed on the clamp body 4.
During dynamic balance running, start worktable, worktable can drive and connect dish 2 rotations, connects dish 2 and drives clamp bodies 4, and clamp body 4 drives spacing collar 5, and spacing collar 5 drives flywheel 14.Like this, just finished the dynamic balance running of flywheel.
