Description

The installation tool and installation method of a kind of bolt spring block
Technical field
The present invention relates to the installation tool and installation method technical field of spring block, more particularly to a kind of bolt spring block installation tool and installation method.
Background technology
Part composite class fastener such as adjustable diameter bolt, is cased with multiple extrusion expansion components on the body of bolt.Need to back out nut when the component is installed, due to being sliding fit between compression assemblies and the body of bolt, to prevent component from coming off, generally there is a block with spring on the body of bolt, block ride out is more than compression assemblies internal diameter, plays the purpose for preventing compression assemblies from coming off.Spring is lined with block, when compression assemblies and nut need installation or removal, block can be pressed with hand, under pressure, block can be retracted in the body of bolt, dog height is less than compression assemblies and nut internal diameter, and compression assemblies or nut can pass freely through stop location, and distress resolves backstop stretches out the body of bolt again.
Each component of block of bolt is installed inside the body of bolt, and block is needed by a block pin through block centre bore come spacing.Block centre bore and block pin are excessively cooperation, ensure that block pin overlaps with block centre bore during installation, it is therefore desirable to which the block pin equipped with spring is accurately positioned.Additionally due to block pin can only be installed from the bottom outlet of bolt tail, bottom outlet depth is more than block pin length, and block pin size is smaller(Less than 2mm), directly install relatively difficult with hand.But the introduction of corresponding block pin installation tool and installation method is not inquired at present, it is necessary to design a kind of special block pin installation tool and installation method.
The content of the invention
In order to solve above-mentioned technical problem, the invention provides the installation tool and installation method of a kind of bolt spring block, the easy purpose for installing block by hand is realized, specific technical scheme is:
A kind of installation tool of bolt spring block, it is characterised in that:Instrument and block pin installation tool are positioned including block, the block positioning instrument is the internal column structure for being provided with a hole, the block pin installation tool includes paxilla and big cylinder, the paxilla diameter is less than big column diameter, connected by cone between the paxilla and big cylinder, blind hole is provided with inside the paxilla front end.
A kind of installation method of bolt spring block, it is characterised in that:Comprise the following steps;
Step one:According to required spring block to be mounted and the size of bolt uropore, block positioning tool sizes are calculated;
Step 2:Instrument is positioned using block to compress spring block, and spring block is fixed on the center of body of bolt tail hole;
Step 3:By in the blind hole inside block pin insertion preprepared block pin installation tool small cylinder;
Step 4:The block pin that block pin installation tool will be inserted is entered in block centre bore by bolt bottom outlet;
Step 5:Apply axial force in block pin installation tool, block pin is arranged on block;
Preferably:Block positioning instrument in the step one is made of common metal or plastic material.
Preferably:The block pin installation tool uses hardness HRC>35 material is made.
Preferably:The block positioning instrument is the internal cylindrical structure for being provided with a hole, the block pin erecting device includes small cylinder and big cylinder, connected by cone between the small cylinder and big cylinder, blind hole is provided with inside the small cylinder front end, the diameter of the blind hole is than the big 0.05mm of block pin diameter.
Key to the invention is that with the size of block and bolt uropore as foundation, positioning tool inner bore size can be calculated, therefore block centre bore can be compressed in the case where instrumental purpose is positioned and overlapped with bolt uropore center, be easily installed.Block pin is smaller and length is less than bolt uropore depth, cannot directly be installed with hand, block pin can be transported to block central hole by block pin installation tool point diameter smaller portions by bolt bottom outlet, and smoothly block pin can be installed on block with after-applied axial force.
The acquired compared with prior art technique effect of the present invention is:The present invention devises the manual installation tool and installation method for body of bolt spring block, by the size design for positioning tool inner bore, can the block of effectively fixing band spring realize being accurately positioned for block centre bore and bolt uropore simultaneously, block pin installation tool solves block length less than bolt bottom outlet depth, the problem of installation site cannot be transported to hand, and pin right angle setting hole direction can be retained stop and installation is smoothly completed, installation tool is simple to operate, used time is short, is suitable to manual installation.
