Abstract
The utility model discloses a double tensioning device for dynamic balance test of a double-mass flywheel, wherein a large tensioning sleeve is connected with a first spring seat, a baffle, a first connecting column and a second connecting column, the first spring compresses the first spring seat to drive the large tensioning sleeve to move downwards, and the conical surface of a core cone drives the diameter of the large tensioning sleeve to be increased so as to tension a primary flywheel; the small expansion sleeve is connected with the pull rod, the second spring seat and the third connecting column are in threaded connection with the base, the second spring compresses the pull rod to drive the small expansion sleeve to move downwards, and the conical surface of the core cone drives the diameter of the small expansion sleeve to be increased so as to expand the secondary flywheel. The utility model has the advantages that the cover that rises greatly rises and the cover that rises slightly independently rises primary flywheel and secondary flywheel respectively, improves the reliability to the cost is reduced.
Description
Technical Field
The utility model relates to a test fixture field, in particular to two tight devices that rise of two quality flywheel dynamic balance tests.
Background
The dynamic balance test needs to be carried out in the manufacturing process of the dual-mass flywheel, and because the primary side and the secondary side of the dual-mass flywheel can rotate relatively due to the structural characteristics of the dual-mass flywheel, a tensioning device is needed on the test equipment, and the primary side and the secondary side of the dual-mass flywheel can be tensioned simultaneously. The existing tensioning devices are imported, so that the cost is high, and the maintenance cost is also high. This is where the application needs to be focused on.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a two tight devices that rise of two quality flywheel dynamic balance tests with low costs will be provided.
In order to solve the technical problem above, the utility model provides a two tight devices that rise of two quality flywheel dynamic balance tests, include:
the large expansion sleeve is connected with the first spring seat, the baffle, the first connecting column and the second connecting column, the first spring is arranged in the first spring seat and tightly presses the first spring seat to drive the large expansion sleeve to move downwards, and the conical surface of the core cone drives the diameter of the large expansion sleeve to be increased so as to expand the primary flywheel;
the small expansion sleeve is connected with the pull rod, the second spring seat and the third connecting column are in threaded connection with the base, the second spring is arranged in the second spring seat and compresses the pull rod to drive the small expansion sleeve to move downwards, and the conical surface of the core cone drives the diameter of the small expansion sleeve to be increased so as to expand the secondary flywheel.
The core cone is connected with the base.
The base is connected with the positioning seat, the positioning seat is used for placing a workpiece, the positioning seat is connected with the positioning pin, and the positioning pin is used for positioning the workpiece.
The utility model has the advantages that:
1) the large expansion sleeve and the small expansion sleeve of the double expansion device of the utility model independently expand the primary flywheel and the secondary flywheel respectively, thereby increasing the reliability of the double expansion device;
2) the structure is simple, the processing and the assembly are easy, and the manufacturing cost and the maintenance cost are reduced.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 and fig. 2 show schematic structural diagrams of embodiments of the present invention. As shown in fig. 1 and 2, the utility model provides a double-tensioning device for dynamic balance test of a dual-mass flywheel, wherein the double-tensioning device is a large-expansion sleeve and a small-expansion sleeve. The core cone 6 is in threaded connection with the base 3, the base 3 is in threaded connection with the positioning seat 4, the positioning seat 4 is used for placing the dual-mass flywheel, the positioning seat 4 is in threaded connection with the positioning pin 5, and the positioning pin 5 is used for positioning the dual-mass flywheel. The large expansion sleeve 7 is in threaded connection with a spring seat A8, a baffle plate 10, a connecting column A9 and a connecting column B11, a spring A12 is arranged in the spring seat A8, a pressing spring seat A8 drives the large expansion sleeve 7 to move downwards, and the conical surface of a core cone 6 drives the diameter of the large expansion sleeve 7 to be increased so as to tension the primary flywheel 1; the small expansion sleeve 13 is connected with the pull rod 14, the spring seat B15 and the connecting column C16 are fixedly screwed with the base 3, the spring B17 is arranged in the spring seat B15, the pull rod 14 is pressed to drive the small expansion sleeve 13 to move downwards, and the conical surface of the core cone 6 drives the small expansion sleeve 13 to increase in diameter so as to tension the secondary flywheel 2. The core cone 6 is fixed with the base 3 by screw connection.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
