Embodiment 1

[0023] Such as figure 1 As shown, when the screw 1 and the nut 2 need to be closely combined, the filling layer 1 in liquid form can be added to the gap between the two parts. When the liquid is solidified, the parts can be tightly combined, and the air can also be prevented from entering, so as to realize the firm combination between the parts and achieve the purpose of safety and efficiency. The filling layer is in a liquid state when it is higher than normal temperature, and is solid in a normal temperature state. The cross section of the screw is circular. The inner diameter cross-section of the nut matches the screw. The outer diameter cross-section of the nut is circular.

Embodiment 2

[0025] Such as figure 2 As shown, when the screw 1 and the nut 2 need to be closely combined, the filling layer 1 in liquid form can be added to the gap between the two parts. When the liquid is solidified, the parts can be tightly combined, and the air can also be prevented from entering, so as to realize the firm combination between the parts and achieve the purpose of safety and efficiency. The filling layer is in a liquid state when it is higher than normal temperature, and is solid in a normal temperature state. The cross section of the screw is circular. The inner diameter cross-section of the nut matches the screw. The outer diameter cross-section of the nut is square.

Embodiment 3

[0027] Such as image 3 As shown, when the screw 1 and the nut 2 need to be closely combined, the filling layer 1 in liquid form can be added to the gap between the two parts. When the liquid is solidified, the parts can be tightly combined, and the air can also be prevented from entering, so as to realize the firm combination between the parts and achieve the purpose of safety and efficiency. The filling layer is in a liquid state when it is higher than normal temperature, and is solid in a normal temperature state. The cross section of the screw is circular. The inner diameter cross-section of the nut matches the screw. The outer diameter cross-section of the nut is a regular hexagon.

Abstract

The invention relates to a fixing device for parts combination. The device comprises a nut, a screw, and a fill layer. The nut is in threaded connection with a screw. The fill layer is arranged at the threaded connection part between the nut and the screw, and is seamlessly connected with the nut and the screw. Compared with the prior art, the device has the following advantages of: being secure and tight: as the filler can fully penetrate into the junction of parts, the close integration between the parts can be achieved, which do not become loose; being safe: as the prior art can not achieve the exact combination between the parts, and the accuracy can not meet the standardized requirements, the perfect combination of materials can be achieved after the addition of the filler, thus improving the machine performance and safety; and being durable: as the filler is completely in a close integration at the junction of parts, which plays the role of isolating the air, corrosion of the parts is prevented and long-term use of the parts is achieved.

Description

technical field [0001] The invention relates to a fixing device, in particular to a component combining fixing device. Background technique [0002] The design and manufacture of today's machinery has not fully achieved the accuracy of the design of a part. The service life of the part will inevitably be affected in the old days, and the use of the machine is not particularly comfortable and safe, so the filler at the joint of the parts It can be the combination of various parts to achieve a firm effect, so that the machine can run stably. [0003] Patent application number 01119187 relates to a fixing device for fixing a machine member having a cylindrical hole to a shaft, wherein a pair of members have mutually facing mating inclined surfaces interposed between the machine member and the shaft, the surfaces move relative to each other to increase the clamping force between the machine component and the shaft, wherein the device includes first and second thin-walled sleeve...
