Abstract
The utility model relates to a quick closing-in replacing device for an annular closing-in self-locking nut. A C-shaped seat body is used as a foundation, a stepped cylindrical guide sleeve and a workpiece positioning seat are press-fit in the seat body, a closing-in end of a closing-in die is inserted into the guide sleeve, and the device is arranged on a press. The quick closing-in replacing device for the annular closing-in self-locking nut has the advantages of convenience in operation, economy and practicality, easiness in implementation, wide use range, and obvious effect, and can be popularized and applied to closing-in of various annular closing-in self-locking nuts.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of annular closing in self-locking nut quick change closing device.
Background technology
Self-locking nut is because it is lightweight, easy for installation, and particularly annular closing in class self-locking nut, does not need special cutting tool special for processing and testing tool, is therefore widely used in the product scopes such as industry, agricultural, science and technology, Aero-Space.The quality of self-locking nut locking property, be directly connected to performance and the life-span of product, and the quality of self-locking nut crimping quality is one of key factor directly affecting its locking property.Therefore, the quality of self-locking nut locking end closing in quality is most important.The more self-locking nut of using at aerospace field is annular closing in class self-locking nut, and annular closing in class self-locking nut has non-metallic insert hexagonal self-locking nut and fluting hexagonal self-locking nut.These two kinds of self-locking nuts are in machine-shaping process, after not only requiring locking end to close up, outside dimension precision is higher, and locking end closing in external diameter and screw thread must have higher axiality, guarantee coupling mechanism force is even, improve product reliable lock and service life, but closing in external diameter and thread coaxiality are measured difficulty, easily cause measure error and affect product locking property, even if adopt special measurement frock to detect screening, control to a certain extent substandard products and flow into next process, but still have larger hidden danger of quality.On the other hand, the outside dimension causing when closing in and coaxiality deviation, cannot only reprocess and scrap, and causes compared with large resource waste and economic loss.Only control closing in quality from the source of closing up, be only the key of dealing with problems.
summary of the invention
The utility model object is for overcoming above-mentioned defect, and technical problem to be solved is to provide a kind of general, easy, annular closing in self-locking nut-crimping device fast.
The utility model provides following technical scheme: a kind of annular closing in self-locking nut quick change closing device, comprise: C shape pedestal, cylinder guide pin bushing, closing in die, positioning seat, lower end at C shape pedestal is provided with positioning seat, upper end is provided with cylinder guide pin bushing, closing in die penetrates in cylinder guide pin bushing, positioning seat is fitted on C shape pedestal, then the closing in end of closing in die is inserted in guide pin bushing.
The utility model annular closing in self-locking nut quick change closing device only needs a C type pedestal and a ladder barrel guide pin bushing, by changing positioning seat and closing in die, can cover the closing in of the locking end annular closing in class self-locking nut such as the various non-metallic insert self-locking nuts of screw thread specification M3～M36, fluting self-locking nut.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model annular closing in self-locking nut quick change closing device.
In figure: 1-C shape pedestal, 2-ladder barrel guide pin bushing, 3-closing in die, 4-positioning seat.
The specific embodiment
The technical solution of the utility model specific embodiment:
As shown in Figure 1, a kind of annular closing in self-locking nut quick change closing device, this measurement mechanism comprises: C shape pedestal 1, ladder barrel guide pin bushing 2, closing in die 3, positioning seat 4.Ladder barrel guide pin bushing and each one of workpiece positioning seat are fitted on pedestal, then the closing in end of closing in die is inserted in guide pin bushing.When closing in, package unit is placed on press bench table top, rotation pressure machine flywheel, moves down press ram, the upper end of closing in die is inserted in slide block die shank installing hole to die shank lock-screw on fastening slide block.Slowly rotation pressure machine flywheel, guarantee that closing in die can steadily slide up and down in guide pin bushing, the annular self-locking nut quick change closing device that closes up is pressed on press bench with pressing plate and tommyhead bolt, adjusts press ram stroke, can complete the closing in of annular closing in class self-locking nut.The utility model annular closing in self-locking nut quick change closing device is by changing the closing in applicable to locking end annular closing in class self-locking nuts such as the various non-metallic insert self-locking nuts of screw thread specification M3～M36, fluting self-locking nuts of closing in die 3, positioning seat 4.
The utility model annular closing in self-locking nut quick change closing device is easy to operate, economical and practical, is easy to realize, and adds formula wide ranges, and successful, can be popularized and applied to the closing in of various annular closing in self-locking nuts.
