Abstract
The invention discloses the controllable fastening screws with fastening face distance, head and threaded shank including integral structure, it is characterized by: more than head being connected with the external screw thread body of rod, the top of the external screw thread body of rod is equipped with and pulls hole, body is pulled to be externally provided in head, body is pulled equipped with internal screw thread, the external screw thread body of rod is equipped with external screw thread, it pulls and is attached between body and the external screw thread body of rod using the screw thread mode of being screwed on, the bottom end face for pulling body is equipped with counterbore, the hole size of counterbore is greater than the physical dimension on head, the depth dimensions of counterbore are greater than the height dimension on head, the difference of counterbore depth dimensions and head height dimension is setting value A；When fastening screw is tightened, the distance between the head lower end face of fastening screw and fastening face are equal to A.The present invention can make the distance between the fastening screw head after tightening and fastening face identical, so that all fastening screws be enable easily to realize the fastening for carrying out same degree to same workpiece surface.
Description
Technical field
The present invention relates to a kind of fastener products, and in particular to a kind of controllable fastening screw with fastening face distance.
Background technique
Currently, for same workpiece surface, if multiple screws are difficult to realize to workpiece surface using multiple screws
The fastening of same degree is carried out, and then leads to workpiece surface unbalance stress.If screw is manipulated with torque wrench, although can be right
Screw imposes same torque, to guarantee there is workpiece surface the fastening of same degree, but condition be need screw to workpiece have compared with
, for the screw-driving occasion of small fastening force, torque wrench does not play the role of due big fastening force, can exist tight
Weight misalignment.In addition, the workpiece to work under certain high-temperature work environments, heated to generate thermal expansion, how to realize in high temperature shape
All fastening screws are made to can be realized the fastening for carrying out same degree to workpiece surface under state, this comes to workpiece service life is improved
It says and is very important, this requires fastening screw under normal temperature state to have identical minim gap or zero clearance to work piece face,
It is difficult to accomplish at present, takes complex measures to be just able to achieve.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the invention is to provide one kind can make the fastening screw head after tightening
The distance between fastening face is all identical, so that it is identical to the progress of same workpiece surface so that all fastening screws is easily realized
The controllable fastening screw with fastening face distance of degree fastening.
The present invention is implemented by the following technical programs:
The controllable fastening screw with fastening face distance, head and threaded shank including integral structure, it is characterised in that: head with
On be connected with the external screw thread body of rod, the top of the external screw thread body of rod, which is equipped with, pulls hole, and body is pulled to be externally provided in head, pull body be equipped with it is interior
Screw thread, the external screw thread body of rod are equipped with external screw thread, pull and are attached between body and the external screw thread body of rod using the screw thread mode of being screwed on, are pulled
The bottom end face of body is equipped with counterbore, and the hole size of counterbore is greater than the physical dimension on head, and the depth dimensions of counterbore are greater than head
Height dimension, the difference of counterbore depth dimensions and head height dimension is setting value A；When fastening screw is tightened, fastening
The distance between the head lower end face of screw and fastening face are equal to A.
The fastening screw of above-mentioned technical proposal can make the distance between the fastening screw head after tightening and fastening face all phases
Together, so that so that all fastening screws is easily realized carries out same degree fastening, concrete operating principle to same workpiece surface
Be: screw when in use, will first pull body and be screwed on the external screw thread body of rod, and then turn and pull body, screw outer spiral shell when pulling body
After rasp bar body, continue to turn and pull body and then threaded shank is driven to rotate, until pulling the bottom end face of body and workpiece surface (fastens
Face) it is in contact, the distance between screw head lower end surface and fastening face just can place thickness apart from interior in A for A(in advance at this time
Comparable gasket), it is then log out and pulls body, the fastening screw head after achieving that all tighten in this way and between fastening face
Distance all, thus enable all fastening screws easily realize to same workpiece surface progress same degree fastening.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is the structural diagram of the present invention,
Fig. 2 is the top-direction view of Fig. 1.
Specific embodiment
As shown, the controllable fastening screw with fastening face distance of the invention, head 2 and spiral shell including integral structure
Bar portion 1,2 or more head are connected with the external screw thread body of rod 5, and the top of the external screw thread body of rod 5 is equipped with interior hexagonal and pulls hole 6, other than head 2
Body 4 is pulled equipped with the external shape of outer-hexagonal, pulls body 4 equipped with internal screw thread, the external screw thread body of rod 5 is equipped with external screw thread, pulls body 4 and outer
It is attached between the screw thread body of rod 5 using the screw thread mode of being screwed on, the bottom end face for pulling body 4 is equipped with counterbore 3, the inner hole of counterbore 3
Size is greater than 2 physical dimension of head, and the depth dimensions of counterbore 3 are greater than the height dimension on head 2,3 depth dimensions of counterbore and head 2
The difference of height dimension is setting value A, and setting value A should tighten situation according to difference and design in advance.It is tight when above structure
Gu the bottom end face that screw was tightened, pulled body is in contact with fastening face, the head lower end face of fastening screw and fastening face it
Between distance be equal to A, certainly, before fastening screw is tightened, should place in advance and the comparable gasket of A dimensional thickness.Specifically
Situation has: when spacer thickness is slightly larger than A size, (gasket will select elastomeric pad, such as the group of rubber pad or plain cushion, spring washer
Close), all screws can impose the fastening force of same degree to same workpiece surface；When spacer thickness is equal to A size, all spiral shells
Nail can carry out identical zero clearance to workpiece surface, zero pressure fastens, or when spacer thickness is slightly less than A size, then all spiral shells
Can be there are the minim gap of same size between nail head and fastening face, the identical minim gap can disappear simultaneously after workpiece thermal expansion
It loses, workpiece can be made to better conform to the work under high-temperature work environment, and so that workpiece is thermally expanded uniform force, and then in the condition of high temperature
Under enable all fastening screws easily realize to same workpiece surface carry out same degree fastening, improve workpiece use the longevity
Life.
