Description
Technical field
The invention belongs to assembling jig technical field, more particularly, to a kind of flexibility folder for cylindrical bay section Butt Assembling
Hold device.This device can be used for clamp different radii cylindrical bay section, and underworker complete cylindrical bay section to tipping
Be equipped with and bay section outer wall auxiliary device installation.
Background technology
In the assembling process of cylindrical plant equipment, need to complete to dock along axis by different bay sections, and engaging
On the bay section outer wall becoming, various auxiliary devices are installed.At present, the Butt Assembling for different radii cylinder bay section needs to pass through
Different types of assembling jig completes the clamping to bay section, and assembly cost is higher, and pacifies on the bay section outer wall completing to dock
Hinder bay section rotation during dress auxiliary device, reduce work efficiency, increased the difficulty of workman's assembling, using more inconvenience, and
And therefore indirectly reduce the precision of assembling, cause equipment to assemble the decline of quality.Additionally, for scientific research activity small batch
Produce, some scientific research institutions can select to complete positioning and the assembling of cylindrical bay section using wooden cushion block, this kind of way precision
Difference, efficiency is low, and assembly difficulty is high.
In order to meet the demand of industrial automation, improve efficiency of assembling, need computer-aided control to complete the right of bay section
Connect and bay section outer wall on auxiliary device installation.In view of the requirement of production cost, same production line should complete as far as possible
The Butt Assembling of different radii bay section, therefore corresponding clamping device should realize the clamping work(to different radii cylinder bay section
Can, and when its outer wall installs auxiliary device, this device can not hinder bay section around its axial rotation.And consider automatization and
The requirement of precision, the regulation for flexible fixture should be automatically performed.Obviously existing apparatus cannot meet the demand.
Consider the impact of the factors such as efficiency of assembling, precision and cost it should a kind of device of design meets cylinder
The demand of bay section Butt Assembling.This equipment should meet the following requirements：First, in order to ensure stablizing during Butt Assembling
Property, multiple spot on cylindrical bay section outer wall can be clamped and be ensured with the precision positioning；2nd, it is the bay section adapting to different radii,
This device should have flexibility, and its retained part should do corresponding adjustment according to different radiuses；3rd, it is to meet bay section
The installation requirements of outer wall auxiliary device, this device retained part can not hinder bay section rotatable around its axis it should also to outside bay section
The installation of wall auxiliary device leaves enough spaces.4th, this equipment should have certain automaticity, easy to use, effect
Rate is high.
At present, domestic Duo Jia mechanism all relates to the assembling jig of bay section docking, and it meets above-mentioned to a certain extent
4 points of requirements, the such as Chinese patent application of Publication No. CN 204171918U, disclose a kind of three axles and move adjustable V-arrangement bracket,
Including undersetting, upper bracket, upper line slideway, beam mechanism, it is vertically directed mechanism, V-arrangement bracket, lower line slideway and leading screw spiral shell
Bar, during use, circular bay section is placed on V-arrangement bracket, completes the accurate docking of bay section by adjusting the motion of three axles.This dress
Put the positioning that can realize cylindrical bay section, be related to a kind of bracket for the docking of large-scale bay section level, vee-block can be realized
Adaptation to different radii bay section.But its exist defect be vee-block can only in the change of narrower range endoadaptation bay section diameter,
And the mode of vee-block positioning is insufficient to the clamping of circular bay section, it is only capable of playing the effect supporting bay section, when bay section needs admittedly
Regularly, this equipment can not meet requirement.And because the external cylindrical surface that this equipment relies on cylindrical bay section realizes bay section around it axially
Rotation, when cylindrical bay section outer wall install auxiliary device after due to its outer surface be no longer the complete face of cylinder, now bay section
Cannot rotate on the apparatus again, therefore can not meet the mission requirements of assembling.
For solving the problems, such as that bay section can not be rotated about axis on fixture, domestic Duo Jia mechanism proposes kinds of schemes.As
The Chinese patent application of Publication No. CN 202291830U, discloses a kind of erection welding device of multi cabin butt girth welding seam,
It is directed to a kind of bracket for the docking of cylindrical bay section, can be used to complete the clamping of circular bay section.Above-mentioned bracket by
Shelf enclosure, roller and half snap ring composition with holes, form a full circle to cylindrical component with two half snap rings with holes during use
Compressed, and due to above-mentioned half snap ring synthesize a complete circle, its can on shelf enclosure smart scroll.This device
Rely on the rotation of the cylindrical bay section of outer wall realization of two half snap rings with holes, meeting bay section in assembling process can be rotated about axis
Requirement and can effectively bay section be positioned.And the deficiency that this device exists is, this device is directed to a kind of circle of radius
Cylindricality bay section is accomplished by a kind of half snap ring with holes of radius and shelf enclosure carries out clamping, is unsatisfactory for the demand of flexible assembly,
Use cost is high.
In order to overcome the defect of bay section fixture bad adaptability, domestic Duo Jia mechanism proposes associated solutions.As Ha Er
Shore polytechnical university Master degree candidate Ma Wuyuan is in its master thesis《Guided missile flexibility general assembly systematic research》(tutor：Yao Zhi
Intelligent, reply in June, 2011 on date) in refer to a kind of bay section fixture, its structure by fixture body, locking nut, claw, rotating shaft with
And pull fastening type toggle quick clip five part composition.Wherein two sections fixture bodies pass through a rotating shaft and are connected, and the other end is drawn by one
Button toggle quick clip is realized connecting.In fixture body, uniform four claws, its axle has screw thread, spiral shell corresponding with fixture body
Hole connects, and is locked by locking nut.Claw can have certain radial direction adjustment amount, to meet regulation of mental activities or clamping different shaped
Number bay section.The advantage of this covering device is that with multipoint clamping bay section and can have certain flexibility, is adapted to different radii
Cylindrical bay section, will not hinder bay section rotatable around its axis and reserve sufficient space to the installation of bay section outer wall affiliated facility.Its
Shortcoming is that the claw to each fixture will manually be adjusted, and this process repeats loaded down with trivial details, and the amount of labour is big, and cannot be accurate
Adjustment claw stretches, and therefore this equipment is it cannot be guaranteed that the positioning precision of bay section, and inefficiency, high labor intensive.
