Abstract
The invention discloses automatic control fastening force screws, 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, counterbore base is equipped with elastic washer, the thickness of elastic washer is added with the height dimension on head is greater than counterbore depth dimensions, and the difference of the two is less than the maximum of elastic washer by decrement.The present invention can make fastening force of the screw after tightening to workpiece surface with same degree, and structure is simple.
Description
Technical field
The present invention relates to a kind of fastener products, and in particular to a kind of fastening screw.
Background technique
Currently, for workpiece surface, if multiple screws are difficult to realize to carry out workpiece surface using multiple screws
The fastening of same degree, and then lead to workpiece surface unbalance stress.If screw is manipulated with torque wrench, although can be to screw
Same torque is imposed, to guarantee there is workpiece surface the fastening force of same size, but condition is that need screw to have workpiece larger
Fastening force, for the screw-driving occasion of smaller fastening force, torque wrench does not play the role of due, can exist tight
Weight misalignment.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the invention is to provide one kind can carry out workpiece surface after tightening
The fastening of same degree, the simple automatic control fastening force screw of structure.
The present invention is implemented by the following technical programs:
Automatic control fastening force screw, head and threaded shank including integral structure, it is characterised in that: more than head be connected with external screw thread
Body is pulled to be externally provided in the body of rod, head, pulls body equipped with internal screw thread, the external screw thread body of rod is equipped with external screw thread, pulls body and external screw thread
It is attached between the body of rod using the screw thread mode of being screwed on, the bottom end face for pulling body is equipped with counterbore, and the hole size of counterbore is greater than
The physical dimension on head, counterbore base are equipped with elastic washer, and the thickness of elastic washer, which is added to be greater than with the height dimension on head, to sink
Hole depth size, and the difference of the two is less than the maximum of elastic washer by decrement.
The fastening screw of above-mentioned technical proposal, structure is simple, can carry out the tight of same degree to workpiece surface after tightening
Gu concrete operating principle is: 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, when
Pull after body screws the external screw thread body of rod, continue to turn and pull body and then threaded shank is driven to rotate, until pull the bottom end face of body with
Workpiece surface (i.e. fastening face) is in contact, and elastic washer is by elastic compression and all identical by decrement at this time, then to screw
Head generates an equal amount of reaction force, and then all screw heads is made to generate the fastening force of same size to workpiece surface,
It can realize that the screw after tightening carries out the fastening of same degree to workpiece surface, easily thus to guarantee that workpiece surface stress is equal
It is even.
Preferably, the top of the external screw thread body of rod, which is equipped with interior hexagonal, pulls hole.The purpose of above-mentioned design makes screw exist
It can smoothly be exited after being tightened and pull body, and guarantee is exited the head of screw, threaded shank during pulling body and will not be generated
Rotation guarantees that screw remains unchanged the fastening force of workpiece surface.
Preferably, the elastic washer is rubber washer.
Preferably, the body of pulling is with the external shape of outer-hexagonal.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
As shown, automatic control fastening force screw of the invention, head 2 and threaded shank 1 including integral structure, head 2 with
On be connected with the external screw thread body of rod 6, the top of the external screw thread body of rod 6 is equipped with interior hexagonal and pulls hole 7, and head 2 is to be externally provided with outer-hexagonal body
Shape pulls body 5, pulls body 5 equipped with internal screw thread, and the external screw thread body of rod 6 is equipped with external screw thread, pull body 5 and the external screw thread body of rod 6 it
Between be attached using the screw thread mode of being screwed on, the bottom end face for pulling body 5 is equipped with counterbore 3, and the hole size of counterbore 3 is greater than head
2 physical dimension, 3 bottom of counterbore are equipped with elastic washer 4, and elastic washer 4 is rubber washer, the thickness of elastic washer 4 and head 2
Height dimension be added and be greater than 3 depth dimensions of counterbore, and the difference A of the two is less than the maximum by decrement of elastic washer 4, should
Difference A be setting value, according to screw specifically tighten situation depending on.
