Abstract
The invention discloses a special fixture for disassembling and assembling a wedge-shaped ring, and the special fixture comprises a support structure, a stretching pin component and a trapezoidal transmission screw; in use, after cylinders are fixed by the support structure, the stretching pin bottom is extended into the installing hole of the wedge-shaped ring I, the head (1) of the trapezoidal transmission screw stands up to the groove on the stretching pin when the trapezoidal transmission screw is tightened by a torque wrench, the trapezoidal transmission screw adopts a lever principle to together move the stretching pin component and the wedge-shaped ring I around the pin axis, at the same time, the axial direction of the stretching pin component is subject to frictional resistance of the wedge-shaped ring I and the spring in the stretching pin component is elongated, so that the spring in the stretching pin component executes circumference movement around the cylinders along with the wedge-shaped ring I to assemble the wedge-shaped ring I; the mechanical structure is saved in force and low and even in pressure functioned on the wedge-shaped ring I and the cylinders, thereby ensuring personnel and product security.
Description
Technical field
The present invention relates to a kind of special tooling, particularly a kind of special tooling for wedge ring dismounting.
Background technology
In cylinder product design process, need to select the connected mode between cylinder, what more generally adopt is that screw connects.Screw connects and wedge ring is connected with following shortcoming:
1, cylinder radial space is taken large;
2, junction structural strength is lower;
3, cylinder air-tightness is difficult to ensure.
Wedge-Ring Connection Structure can overcome above-mentioned shortcoming, but its complex structure and require strict to assembly and disassembly methods.
The typical structure that wedge ring connects comprises three parts: cylinder I, cylinder II and a pair wedge ring.During assembling, need cylinder I cover to receive and cylinder II completes cabin body circumference and locate and alignment pin is installed and fix.Again the installing hole of a wedge ring from cylinder I is installed along clockwise, further another wedge ring is installed along counterclockwise from installing hole.
In addition, wedge ring install after stressing conditions comparatively complicated, for wedge ring II, it is subject to 5 frictional force respectively, and these 5 power not only hinder wedge ring dismounting, and there will not be loosening after also ensure that wedge ring installation, that is these power should overcome and are used again.Assembling in early stage needs two people to adopt the mode of knocking to complete simultaneously, and damage larger product rejection rate to cylinder product and wedge ring high, wedge ring assembly difficulty is large.
Further, be difficult to ensure that it is in place, also cannot judge whether it is in place after wedge ring dismounting, namely the operability of this operation is all poor with the property examined.Adopt early stage the way of rocking cabin body to test, security is difficult to ensure.
Further, wedge ring unloading process still needs two people to adopt the reverse mode of knocking to complete simultaneously, and damage larger product rejection rate to cylinder product and wedge ring high, wedge ring dismounting difficulty is large.
Summary of the invention
The present invention adopts lever principle jackscrew to drive telescopic pin to promote the motion of wedge ring; Provide a kind of stable, laborsaving, can one man operation, effectively prevent damaged products, quantization operation and the property examined to be used on the mechanical device of wedge ring dismounting.Concrete scheme is as follows:
For a special tooling for wedge ring dismounting, comprise supporting construction, telescopic pin assembly and trapezoidal turn-screw;
Supporting construction is made up of snap ring I, snap ring II, hoop I, hoop II, two double end connecting studs and supporting component.
Hoop I is fixedly connected with integral with snap ring I, and hoop II is fixedly connected with integral with snap ring II, and hoop I and hoop II distinguish preset trapezoidal turn-screw screwed hole; On hoop I and hoop II, be positioned at trapezoidal turn-screw screwed hole both sides and have screwed hole, two double end connecting stud two ends are equipped with screw thread, snap ring I and snap ring II are connected into the domain by the screwed hole on hoop I and clip II by double end connecting stud, and then domain snap ring I and snap ring II connected into is fixing on the cylinder.
Supporting component comprises a supporting traverse and two support cant beams.Preset telescopic pin installing hole a and pin shaft hole on supporting traverse; The one end supporting cant beam and supporting traverse is threaded with hoop I respectively by supporting component installing hole preset on hoop I; Supporting traverse and support the cant beam other end and be equipped with hole, supporting traverse and two support cant beam passing hole, pin I is hinged, supports cant beam and serves supporting role to supporting traverse, ensure that the intensity of supporting traverse.
Telescopic pin assembly comprises telescopic pin joint, telescopic pin sheath, spring, pin II and telescopic pin, preset telescopic pin installing hole b on telescopic pin joint; Telescopic pin joint and telescopic pin sheath are threaded connection, and can macroscopically regulate telescopic pin assembly overall length; Preset spring in telescopic pin sheath; There is continuous groove telescopic pin both sides, and bottom telescopic pin, protruding end is cylinder, can fully contact with wedge ring I installing hole, and the power of applying process stabilization is controlled, can realize the limit function to wedge ring I, wedge ring II; The slotted hole that pin II passes in telescopic pin, telescopic pin sheath both sides are preset, telescopic pin sheath is connected with telescopic pin, ensure that the integraty of telescopic pin sheath and telescopic pin when telescopic pin compression or extension spring move up and down, the object being regulated telescopic pin length component by spring on microcosmic can be realized again simultaneously.
Trapezoidal turn-screw is connected with hoop I and hoop II by trapezoidal turn-screw screwed hole, and turn-screw screwed hole plays guide effect to trapezoidal turn-screw on the one hand, can ensure the stationarity of transmission efficiency and transmission on the other hand.Trapezoidal turn-screw head is taper rounding, can with the continuous groove of telescopic pin both sides select with the use of.
Supporting traverse and telescopic pin assembly are by telescopic pin installing hole a preset on telescopic pin installing hole b preset on telescopic pin joint and supporting traverse and pin shaft hole and pinned connection, such structure ensures that telescopic pin assembly can swing in certain angle around bearing pin, and telescopic pin assembly can be up and down.
During use, after supporting construction fixes cylinder product, will stretch in the installing hole of wedge ring I bottom telescopic pin, now telescopic pin assembly one end be limited in bearing pin, and the other end is by the resistance of wedge ring I.When turning trapezoidal turn-screw with torque spanner, trapezoidal turn-screw 1 head withstands the groove in telescopic pin, trapezoidal turn-screw application lever principle makes telescopic pin assembly force wedge ring I to move around bearing pin together, the frictional resistance that simultaneous retractable pin assemblies is axially subject to wedge ring I causes telescopic pin assembly inner spring to extend forcing telescopic pin assembly to follow wedge ring I circling around cylinder product circumference, reach the object forcing wedge ring I along cylinder circumferential movement, thus complete the assembling of wedge ring I.
Further, based on the single assembling completing opposite side wedge ring II of same principle, reverse operation also singlely can complete dismounting wedge ring I and wedge ring II.
The process stabilization that bottom telescopic pin, protruding end applies power to wedge ring I installing hole is controlled, knock mode without the need to adopting, therefore damage can not be caused to wedge ring I and cylinder product, and whole wedge ring I program is installed, one man operation can complete, and achieves the optimization of human resources; This frame for movement is laborsaving, and the pressure acting on wedge ring I and cylinder product is little and even, ensure that the safety of personnel and product.
