Specific embodiment
As depicted in figs. 1 and 2, according to the positioning fixture of the side tight lantern ring type waterproof roll of the present embodiment, it includes base
1st, the both sides being actively located at base 1 and waterproof roll can be clamped two clamping plates 2, be used for driving two clamping plates 2 relatively to transport
Dynamic drive mechanism.
Specifically, the length bearing of trend that this drive mechanism is included respectively along every piece of clamping plate 2 is outside from the end of clamping plate
Extend and width become narrow gradually locating piece 3, be separately positioned on clamping plate 2 both ends and the die cavity that can match with locating piece 3
4th, it is used for promoting the push rod 5 that die cavity 4 moves, power source along clamping plate 2 length direction, wherein, die cavity 4 is from towards locating piece 3
End face caves inward and forms groove 40, and when the die cavity 4 at both ends moves to locating piece 3 respectively, locating piece 3 is along groove 40
Side wall moves into die cavity 4, with the outer inclined-plane of locating piece 3 and the side wall of groove 40 so that two clamping plates 2 gradually draw close and
Clamping waterproof roll.
Meanwhile, above-mentioned positioning fixture also includes enabling to locating piece 3 two after losing the stress that die cavity 4 produces to it
The return unit 6 that block clamping plate 2 resets.
Specifically, the clamping plate 2 positioned at base 1 both sides, locating piece 3 are symmetrical arranged with regard to the centrage of base 1 length direction.
The draw-in groove 11 extending (direction of motion of clamping plate 2) along its own width is provided with base 1, in clamping plate 2
Bottom is provided with the clamp 20 being movably arranged as in draw-in groove 11.
In this example, draw-in groove 11 is in inverted t type with the section of clamp 20.And then the movement of clamping plate 2 can be limited so that clamping plate
2 can only move back and forth along the bearing of trend of t type draw-in groove 11.Guarantee that two clamping plates 2 remain to be arranged in parallel.
Further, the cross section of locating piece 3 is in a rectangular trapezoid, and the cross section of groove 40 is in isosceles trapezoid, and isosceles ladder
Another base angle that the base angle of shape is removed outside right angle with right-angled trapezium is equal.
Specifically, between the base angle of isosceles trapezoid is 45 °～80 °.
In this example, the base angle of isosceles trapezoid is 68 ° (in conjunction with Fig. 2), in the case of not considering frictional force, acts on clamping plate
Air pressure on 2 provides 2.5 times (tan68 ° of ≈ 2.5) of pressure that is to say, that in the pressure conversion providing air pump being in for air pump
After chucking power between two clamping plates, 2.5 times of effects of chucking power can be increased, so that the more stable clamping waterproof of clamping plate
Coiled material.
In the same manner, for the trapezoidal wing plate (positioning needing raising pressure to increase the during multiple it is only necessary to suitable base angle of selection
Block) and supporting corresponding die cavity.Therefore, in this example, locating piece 3 is matched with the groove 40 of die cavity 4, and is able to tear open
That unloads is located on clamping plate 2 and push rod 5, thus the die cavity 4 being more suitable for can be selected according to the characteristic of different types of waterproof roll
With locating piece 3.
Return unit 6 is spring, and has two, and is located at respectively between two locating pieces 3 at clamping plate 2 two ends.Specifically may be used
In conjunction with Fig. 2, but it is worth explaining, return unit 6 has the effect of two aspects: is on the one hand common reset function；Another
Aspect be so that clamping plate 2 in clamping waterproof roll more steadily it is ensured that clamping plate 2 mistake that will not be subject to the change of knife stress and occur
Position or skew, so that clamping plate 2 is in motor process, also keep opposing parallel state, consequently facilitating the stabilization clamp of waterproof roll
Hold.
Additionally, power source is air pump (or air compressor), drive mechanism also includes the plunger shaft being connected with air pump
7, what push rod 5 can stretch is arranged in plunger shaft 7.
The specific implementation process of the present embodiment is as follows:
Air pump work so that push rod 5 promotes die cavity 4 to move to locating piece 3, the outer inclined-plane of locating piece 3 now gradually with
The sidewall contact of groove 40, under the cooperation on inclined-plane and inclined-plane so that two pieces of opposing clamping plate 2 along t type draw-in groove bearing of trend
Move closer to, until clamping the both sides of waterproof roll, return unit 6 now is in compressive state；When shedding pressure, die cavity 4
It is gradually disengaged with locating piece 3, and two clamping plates 2 slowly reset under return unit 6 auxiliary, until die cavity 4 is completely de- with locating piece 3
From rear, two clamping plates 2 recover to original state.
In sum, this enforcement is mainly by the perpendicular clamping with clamping plate direction of stress transmission along clamping plate direction
Power, realizes relatively drawing close and clamp of two clamping plates by the way of side is tight, and groove and locating piece are tightly mainly passed through in side therein
Cooperation, this groove similar to a collar, is gradually reduced by the internal diameter of the collar and realizes relatively drawing close of two pieces of locating pieces, that is, real
The relative of existing two clamping plates is drawn close.
Above the present invention is described in detail, its object is to allow the personage being familiar with this art will appreciate that this
The content of invention is simultaneously carried out, and can not be limited the scope of the invention with this, all spirit institutes according to the present invention
The equivalence changes made or modification, all should cover within the scope of the present invention.
