Abstract
The invention discloses a method for separating parts by a thread hole. In a projection surface range of contact surfaces of two solids, one solid is selected, a thread hole with a general specification is formed in an area of the solid capable of operating without influencing functions, and the other solid is self solid in the projection area of the thread hole; when the disassembly is needed, a screw with a corresponding specification is loaded in the thread hole, and the rotating force of the screw is converted to multiple times of pushing force so as to overcome the binding force to separate the two solids. The method can thoroughly separate the contact planes of the two solids under the effect of binding force in a connecting state to prevent the condition of polluting working planes and tools.
Description
Technical field
The present invention is that a kind of screwed hole that uses can the method for light and handy separating component, relates to the improvement of the metal structure of electronic power parts.
Background technology
In the application of power electronics, usually power model or (PCC) power can be installed on a heat sink.Usual way is: add heat-conducting silicone grease at the contact surface place of two parts, then they locked with screw, allows two parts fully contact, to ensure best heat-conducting effect.
In above-mentioned installation process, heat-conducting silicone grease has filled up the not closely sealed space of contact surface, and their air of contact surface is almost all extruded again by screw locking process, and joint is in almost vacuum state immediately.Due to the effect of atmospheric pressure, their contact surface is larger, and atmospheric pressure is larger, and the vacuum adsorption force between them is larger, adds the comprehensive cohesive force that the adhesion of heat-conducting silicone grease produces simultaneously, and this is very favourable to installation process, as shown in Figure 1.
But in unloading process, this comprehensive cohesive force hinders exactly.Tear little power device open can manage it, tear a large point module or assembly open just unbearable.Gap between power component and radiator contact surface, screwdriver of generally whipping not again inserts; The carefully thin metallic rod cohesive force that unable antagonism is larger again, in a word can not be neat and tidy in dismounting, and the scope of operation and instrument can be polluted by heat-conducting silicone grease often, has influence on the outward appearance after removal efficiency and maintenance.
Summary of the invention
For dismounting in not convenient, unclean problem, the present invention proposes a kind of method that screwed hole makes isolation of components, under the state that the contact plane of two entities is linked together under cohesive force effect, can be separated with a snap.
Technical scheme of the present invention is as follows:
A kind of screwed hole makes the method for isolation of components, within the scope of the perspective plane in two material contact faces, select one of them entity, its can operation, the region that do not affect again its function, the screwed hole of a common-use size is set, require that the view field of another entity residing for described screwed hole is for himself entity, be not namely passing condition state simultaneously herein; When needing dismounting, in screwed hole, load the screw of a dimension, utilize it revolving force to be converted to the pushing force of several times, overcome cohesive force by two entity separation.
Further, the specification of described screwed hole and the installation screw thread specification of two entities consistent.
Advantageous Effects of the present invention is:
Adopting the present invention, on the power model of power electronics and the heat radiating metal base of power modules, placing a screwed hole for dismantling; Usually, the specification of this screwed hole is consistent with the installation screw thread specification of power model and power modules, and the screw of dismounting just can obtain smoothly, so just more improves the Discussing Convenience of engineering.
By simple screwed hole, engineering staff can be made away from the past in the face of the scope of operation and the contaminated embarrassment of instrument.
Accompanying drawing explanation
Fig. 1 is parts connection status figure.
Fig. 2 is screwed hole state diagram.
Fig. 3 is isolation of components state diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 2, within the scope of the perspective plane in two material contact faces, select one of them entity 2, its can operation, the region that do not affect again its function, the screwed hole of a common-use size is set, require that the view field of another entity 1 residing for its screwed hole is for himself entity, namely must not be passing condition state simultaneously herein.
As shown in Figure 3, when needing dismounting, load the screw of a dimension at screwed hole, utilize it that revolving force of screwdriver is converted to the pushing force of several times, just can overcome cohesive force like a cork, by two isolation of components.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
Claims (2)
1. one kind makes the method for isolation of components with screwed hole, it is characterized in that: within the scope of the perspective plane in two material contact faces, select one of them entity, its can operation, the region that do not affect again its function, the screwed hole of a common-use size is set, require that the view field of another entity residing for described screwed hole is for himself entity, be not namely passing condition state simultaneously herein; When needing dismounting, in screwed hole, load the screw of a dimension, utilize it revolving force to be converted to the pushing force of several times, overcome cohesive force by two entity separation.
2. screwed hole according to claim 1 makes the method for isolation of components, it is characterized in that: the specification of described screwed hole is consistent with the installation screw thread specification of two entities.
