Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0017] refer to Figure 1-2 , a closing device for fasteners, comprising a base 1, the top of the base 1 is fixed with a column 2 by bolts, the top of the column 2 is fixed with a support platform 4 by hexagonal screws, and the upper surface of the support platform 4 is welded with The support plate 7, through the setting of structures such as the support plate 7, the spring 8, and the clamping plate 9, when the fastener is placed, the elastic force of the spring 8 can push the clamping plate 9 to clamp and fix the outer side of the fastener. Workpieces of all sizes can be quickly fixed, easy to use, one side of the support plate 7 is welded with a spring 8, the othe...

Abstract

The invention relates to the technical field of closing-in devices, in particular to a closing-in device for a fastener. The closing-in device overcomes the defects of high limitation and low processing precision in the prior art. The closing-in device comprises a base. A stand column is fixedly arranged on the top of the base by bolts. A support platform is fixedly arranged at the top of the stand column through a hexagonal screw. Support plates are welded to the upper surface of the support platform. A spring is welded to one side of each support plate, and a clamping plate is welded to theother end of each spring. A servo motor is mounted on the top of the base through screws. The output end of the servo motor is connected with a rotating shaft through a coupling. By arranging the structures such as a rotating disc, the support platform, a ring groove, the servo motor, extrusion blocks and a scale, after the servo motor drives the rotating disc to rotate, the fastener can be subjected to closing-in by the extrusion blocks automatically, in cooperation with the scale reading, the closing-in size can be accurately controlled, and the high-precision processing requirement can be met.

Description

technical field [0001] The invention relates to the technical field of closing devices, in particular to a closing device for fasteners. Background technique [0002] Use the equipment to force the fastener to deform in the radial direction. The deformed part is the closure. The closure allows the fastener to form an interference fit during assembly, and the radial compression generates friction to prevent loosening. The structure of the fastener , external dimensions, materials, heat treatment, thread manufacturing tolerances, etc., will affect the friction torque at the closure to a certain extent, but when the above conditions are certain, the most critical factor is the closure size of the fastener. [0003] The closure device in the prior art has the following defects: First, the fasteners cannot be quickly fixed to fasteners of all sizes due to the different sizes, which has high limitations. In addition, the size control of the closure is inaccurate, and the machining...
