Abstract
The utility model relates to a correcting device for locking torque of a self-locking nut. The correcting device comprises a core rod of a cylindrical structure and a correcting base, two ends of the core rod are round sharp edges, the core rod matches with a central hole in the correcting base which is integrally of a cylindrical step structure, a thread is formed on the outer surface at one end of the correcting base, a cross recess is formed in the thread end axially, and the central hole is positioned at the center of the correcting base and axially penetrates through the whole correcting base. The correcting device for locking torque of the self-locking nut is simple in structure, easy to implement, safe and reliable in effect and capable of reducing economic loss, can be popularized and applied to all kinds of machinery industries and has good economic and social benefits.
Description
Technical field
The utility model belongs to mechanical manufacturing field, particularly a kind of means for correcting of self-locking nut.
Background technology
Closing in type self-locking nut is to make screw thread produce certain distortion by nut is closed up, thereby makes threaded connection pair in the situation that not bearing axial load, needs certain rotating torque when smooth rotation nut.Between this moment energy effective impedance threaded connection pair, relatively rotate, thereby realize the self-locking locking function of nut.
The closed up impact of the many factors such as size, heat treatment, surface treatment of the size of the locking torque of closing in type self-locking nut, therefore, in process, strictly control various factors.Self-locking nut is as defective in found locking torque in the time of performance test, can only scrap, and has produced thus very large economic loss.
Utility model content
For overcoming above-mentioned defect, the defective device of doing over again and proofreading and correct of locking torque when the technical problems to be solved in the utility model is to provide a kind of self-locking nut when discovery finished product in performance test.
A means for correcting for self-locking nut locking torque, this means for correcting is made up of plug and correction base; The cylindrical structure of described plug, two ends sharp edge is mellow and full, matches with the heart hole of proofreading and correct on base; Described correction base entirety is cylindrical shape ledge structure, is provided with screw thread at its one end outer surface; In axial direction be provided with cross recess at the end of thread simultaneously; Heart hole is positioned at the center of proofreading and correct base, axially runs through whole correction base.
The utility model means for correcting is simple in structure, easy to implement, effect is safe and reliable, can effectively reduce economic loss simultaneously, can be popularized and applied to various machinery industries, has good economic benefit and social benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In self-locking nut production process in the past, when the self-locking nut of finished product is as defective in discovery locking torque super large in the time of performance test, can only scrap processing, produce thus very large economic loss.For this phenomenon, technical staff, by research, designs a kind of locking torque means for correcting.As shown in Figure 1, Figure 2, Figure 3 shows, a kind of device that can proofread and correct the self-locking nut of the locking torque super large having closed up, this device is made up of plug 1 and correction base 2.The cylindrical structure of plug 1, two ends sharp edge is mellow and full, matches with the heart hole 5 of proofreading and correct on base 2.Proofreading and correct base 2 entirety is cylindrical shape ledge structure, is provided with screw thread 3 at one end outer surface of proofreading and correct base 2, is connected for the self-locking nut of proofreading and correct with need; Simultaneously in axial direction be provided with cross recess 4 at its end of thread so that the self-locking nut that needs to proofread and correct while screwing in cross recess 4 shrink to be spun on easily and proofread and correct on base 2.Heart hole 5 is positioned at the center of proofreading and correct base 2, axially runs through whole correction base 2.
Operation principle of the present utility model is: the self-locking nut that need are proofreaied and correct is spun on and is proofreaied and correct on base 2 by screw thread 3, opened vertically cross recess 4 owing to proofreading and correct base 2, when the self-locking nut that need proofread and correct is screwed in, cross recess 4 shrinks and self-locking nut can be spun on easily proofread and correct on base 2.Plug 1 is pressed into from heart hole 5, self-locking nut is carried out to bulging, reversible deformation is played at the position that makes to close up, thereby reaches the object of the locking torque that changes self-locking nut.
The utility model means for correcting be the self-locking nut of finished product in the time that performance test generation locking torque super large is defective, do over again proofread and correct a kind of device.Control reversible deformation degree by adjusting the outside dimension of plug 1 and the screw-in depth of self-locking nut, thereby obtain qualified locking torque.The utility model is simple in structure, easy to implement, effect is safe and reliable, can effectively reduce economic loss simultaneously.
