Abstract
The utility model relates to a positioning installation screw bolt with controlled torque. The positioning installation screw bolt consists of a twisting part, a twist-off part, a cone positioning part, a guide part and a screw thread part, wherein the twisting part and the twist-off part are arranged at one end of the cone positioning part and are integrated with the guide part and the screw thread part; the cone positioning part and the screw thread part are arranged at two ends of the guide part; in the installation and connection process, the twisting part is twisted to screw the positioning screw bolt in place through the guide part and the cone positioning part; after the whole connection process ends, the twisting part and the twist-off part are twisted off from the end part of the cone positioning part; and the twisting part can be made into a shape of an external hexagon, an internal hexagon or an external duodecagon. The positioning installation screw bolt is characterized in that through a cone pin part and the twisting part which are added on an ordinary screw bolt, the installation torque of the screw bolt is controlled, the reliability of the installation position is guaranteed, the problem that the installation bodies are damaged due to excessive torque is prevented, a special installation tool is not required, and therefore the installation efficiency is greatly improved.
Description
Technical field
The utility model belongs to mechanical manufacturing field, and particularly a kind of torque-controllable is installed holding down bolt.
Background technique
The many casings of machinery industry and cover board connection structure need to be installed holding down bolt, and these connection parts are higher to pretightening force (mounting torque) control, position accuracy demand.Therefore need a kind of mounting torque to control and the bolt that can play the role of positioning again connects, to guarantee that mounting torque in claimed range, can guarantee again the positional accuracy between casing and the cover plate simultaneously.
The model utility content
The technical problems to be solved in the utility model provides a kind of registration and the controlled holding down bolt of mounting torque.
A kind of torque-controllable is installed holding down bolt, comprises the twisting position, twists into two parts the position, paniculidine bit position, targeting part, helical thread portion; The twisting position, twist into two parts the end that the position is positioned at the paniculidine bit position, be integrated with targeting part and helical thread portion; Paniculidine bit position, helical thread portion are positioned at the two ends of targeting part;
When connection is installed, turn the twisting position and by targeting part and paniculidine bit position the holding down bolt twisting put in place, after integrated connection is good, at last with the twisting position, twist into two parts position integral body and twist into two parts from the end of paniculidine bit position.
The twisting position can be made into outer-hexagonal, interior hexagonal or outer 12 jiaos.
Compare with plain bolt, taper pin, the utility model is by increasing taper pin part and twisting position at plain bolt, controlled the bolt mounting torque, can also play the effect of location, both guaranteed the mounting point reliability, avoid simultaneously the excessive damage of moment that matrix is installed, and do not needed special installation tool, greatly improved installation efficiency.
Description of drawings
Fig. 1 is the structural representation that the utility model can be controlled the mounting torque bolt.
Embodiment
The technical solution of the utility model is connected with bolt for having increased taper pin position, twisting position at plain bolt, and the twisting position can be made into difformity, such as outer-hexagonal, interior hexagonal, outer 12 jiaos etc., to satisfy different installation conditions requirements.The utility model is by selecting different materials to make the bolt of different intensity grades, be used for the connection of varying strength claimed structure, the prerequisite that guarantees the mounting point can guarantee mounting torque again, the mounting torque full accuracy reaches the 0.2N.m scope, remove as the mounting process piece at the twisting position after installing, and does not increase overall weight.
As shown in Figure 1, the utility model can control that the mounting torque bolt comprises twisting position 1, twists into two parts position 2, paniculidine bit position 3, targeting part 4, helical thread portion 5.Twisting position 1, twist into two parts the end that position 2 is positioned at paniculidine bit position 3, be integrated with targeting part 4 and helical thread portion 5; Paniculidine bit position 3, helical thread portion 5 are positioned at the two ends of targeting part 4.When connection is installed, turn twisting position 1 and by targeting part 4 and paniculidine bit position 3 the holding down bolt twisting put in place, after integrated connection is good, at last with twisting position 1, twist into two parts position 2 integral body and twist into two parts from the end of paniculidine bit position 3.Twisting into two parts the size at position 2 can determine according to the size of bolt.
The utility model can be selected different materials according to different needs, to the bolt of mounting torque requirement not too high (more than 0.3～0.5N.m), twists into two parts the position and can process before heat treatment; To the bolt that mounting torque is had relatively high expectations, twist into two parts the position and can after heat treatment, process.Twist into two parts spot size control by adjustment and twist into two parts moment, thus the mounting torque of control bolt.
Compare with the plain bolt technology, the utility model has been controlled the bolt mounting torque by increased paniculidine bit position 3 and twisting position 1 at plain bolt, can also play the effect of location, has both guaranteed the mounting point reliability, has improved simultaneously installation efficiency.Setting tool is required to reduce, need not measure detection, simplify working procedure, many important connection parts are had very high application prospect, especially Aero-Space, nuclear industry field and machinery industry can be widelyd popularize, and have good economic benefit and social benefit.
