Description
Technical field
The present invention relates to lock screw technical field, the outdoor application product lock screw works of espespecially a kind of higher waterproofing grade
Skill.
Background technique
The Product Assembly of LED lamp (such as outdoor use projecting lamp), including the assembly in lamps and lanterns upper casing and lower casing.It is general next
It says, after glass is installed between upper casing and lower casing, also sealing ring can be installed in the seam crossing of upper casing and lower casing, to improve product
Entirety is dust-proof, waterproof performance.After being placed in sealing ring between upper casing and lower casing, need to lock spiral shell on the periphery of upper casing and lower casing
Silk fixes lamps and lanterns assembly.
Referring to Fig. 5, traditional locks screw technique is direct lock screw, the compression of sealing ring is eliminated during locking screw
Amount.It locks screw setting torsion T=lock screw torsion t1+ and eliminates the torsion t2 that sealing ring decrement needs.With locking screw
Quantity increases, and sealing ring thickness is smaller and smaller, and the torsion that t2 needs is smaller and smaller, and T is definite value, so t1 will increase.This is just
There are following two drawbacks: will lead to sealing ring over-voltage when locking last screw, over-voltage can make the service life of sealing ring shorten；
The process of the boil down to dynamic compression of sealing ring, is easy to appear the non-uniform phenomenon of compression, and compression unevenly will lead to local infiltration
The problem of leakage.
Summary of the invention
To solve the above problems, the present invention provides a kind of outdoor application product lock screw technique of higher waterproofing grade,
The outdoor application product for solving higher waterproofing grade directly locks screw by traditional locks screw technique and (does not carry out precompressed and eliminate sealing
Enclose decrement), lock end screw unevenly shortens and product seepy question with the sealing ring service life caused by over-voltage because of sealing ring compression.
To achieve the above object, the technical solution adopted by the present invention is that: first clamp workpiece, sealing ring compression is eliminated in precompressed
Amount, makes sealing ring reach optimum thickness, then lock screw.Guarantee that sealing ring compresses uniformly/not over-voltage, good seal.
The production technology comprises the following steps that
Step 1 calculates sealing ring decrement (sealing ring decrement Δ=H1-H2, wherein H1 is sealing ring before compressing
Thickness, H2 are the thickness of sealing ring after compression), and clamp system is designed and produced according to workpiece (cylinder, oil cylinder or machine can be used
Tool gear grips, over-voltage caused by clamp system needs to determine block with travel switch or machinery to prevent stroke excessive)；
Workpiece is packed into clamp system by step 2；
Step 3 is clamped workpiece using clamp system, the disposable decrement for eliminating workpiece inner seal ring entirety；
Step 4, lock screw or nut；
Step 5 unclamps clamp system, takes out workpiece.
The beneficial effects of the present invention are: the invention discloses dust-proof, waterproofing grade be IP66~68, to be related to sealing ring close
The lock screw technique of envelope, fastened by screw (screw quantity is greater than 4pcs) product, comprising the following steps: 1. calculate sealing ring compression
Amount, designs and produces clamp system；2. filling workpiece to clamp system；3. clamping, sealing ring decrement is eliminated；4. lock screw；5.
It unclamps clamp system and takes out workpiece.Above-mentioned technical proposal " first clamps, eliminate sealing ring decrement, then lock screw ", guarantees sealing
Circle is pressurized uniformly, will not compress unevenly because of sealing ring after locking screw and screw does not lock caused leakage, sealing ring office
Service life caused by portion's over-voltage shortens problem.
