Description
Technical Field
The utility model relates to a dynamic balance anchor clamps.
Background
The current clamps for dynamic balancing are generally of the following two types: the balance method can simulate the working state of the part more truly, but a cantilever structure appears in the clamping of the part, so that the stability of the balance precision is reduced. The other is to mount a bearing on the part datum for dynamic balance, the balance mode can model the working state of the part and can provide enough part rigidity, but due to the existence of axial clearance and radial clearance of the bearing, part balance errors can be generated, particularly when a high-precision part is balanced, the errors are greatly influenced, and the clamping is troublesome.
Disclosure of Invention
The utility model discloses the main technical problem who solves is: how to clamp parts in dynamic balance test.
The technical scheme of the utility model is that:
the utility model provides a quick clamping's high accuracy is from deciding cardiac balance anchor clamps, includes the dabber, is fixed with supporting disk and setting element on the dabber, and the setting element outside sets up the gland, adjusts the gland through installing the adjusting nut of spindle for the distance of setting element, and the gland excircle has certain tapering.
The mandrel is a stepped shaft, two ends of the mandrel are thin, the middle of the mandrel is thick, and one end of the mandrel is provided with an adjusting nut, a gland, a positioning piece and a supporting disk sequentially from outside to inside on shaft sections with different diameters.
The adjusting nut is arranged on the thread section of the mandrel, and the inner side of the thread section is a finishing section for installing the gland.
The adjusting nut is of a two-stage stepped tubular structure, threads are arranged on the inner wall with the smaller diameter, and the part with the larger diameter can be sleeved on the finish machining section.
The supporting disk is in a disk shape, and bolts are arranged on the outer edge of the disk.
A circle of round holes are formed in the supporting disc.
And a gasket is arranged between the gland and the positioning piece.
The gasket is sleeved on the convex edge of the left end face of the positioning piece.
The dynamic balance clamp takes a mandrel as a main component, a supporting disc is used for tensioning and is used as a working reference of a part, a positioning piece is used for supporting a gasket, the gasket is used for limiting the axial movement position of a nut, a certain taper is arranged on the excircle of a gland and is used for compressing the part and centering the part, the nut is used for compressing the gland, when the nut is screwed down, the gland moves axially, and the part is automatically centered when the part is compressed.
The utility model has the advantages that:
(1) the welding device has simple structure, and the clamping and positioning are rapid and stable;
(2) the processing period is short, the clamping and the dismounting of the clamp are convenient, and the tack welding time is short;
(3) the cost is low, and the clamp is formed by splicing standard blocks and can be repeatedly utilized. The time and high cost for manufacturing the special fixture are saved.
