The specific embodiment
Such as Fig. 1 to Fig. 3, this three figure has showed a kind of its primary structure of positioning pressure pin device of present embodiment:
In the present embodiment, the movable rotation-shaft for pad is the rotating shaft of a motor; The purpose of this device, be will with pin 19 along movable rotation-shaft 11 radially pass simultaneously coaxial 13 and movable rotation-shaft 11, movable rotation-shaft 11 is provided with the first pin hole 14, coaxial 13 is the part of a worm.
Fix a fixed mount 20 at the slide rail 9 of strip, this fixed mount 20 can carry out spacing to main body 12; A travelling carriage 30 is arranged, can fixedly be plugged on it described movable rotation-shaft with coaxial 13 of the second pin hole 15; Described travelling carriage 30 is snug fit at slide rail 9, and this travelling carriage 30 is fixed coaxial 13 in position and attitude, and makes the first pin hole of the second pin hole 15 alignment activity rotating shafts 11 of coaxial 13, makes the two relatively fixing; A guide pin 51 that can vertically penetrate movable rotation-shaft 11 its first pin holes 14 is arranged below movable rotation-shaft 11, and this guide pin 51 is that axial sliding fit is in the below of slide rail 9; And the pad mechanism 4 that is used for pad is positioned at the top of slide rail 9 and movable rotation-shaft 11, and adopts the mode that presses down to squeeze into movable rotation-shaft 11 and coaxial 13 by a pad head 40 fixing pins 19.
Fig. 4 travelling carriage 30 has an accommodation chamber 31, coaxial 13 is that square from it opening loads and unloads, accommodation chamber 31 has limited coaxial 13 in position axial, that the footpath makes progress, especially, accommodation chamber 31 also has the rotation that stopper slot 32 clampings that vertically arrange are prevented coaxial 13, locates its circumferential position.In the translation of travelling carriage 30, can be inserted in movable rotation-shaft 11 for coaxial 13 and can not be offset, rotate.
Fig. 5 is the first view of present embodiment; Fig. 6 is the second view of present embodiment; Fig. 7 is the third state schematic diagram of present embodiment; This three figure has only showed the relation between the movable part, has omitted some fixed parts; In conjunction with this three figure, by a complete pad circulation present embodiment is described:
After at first main body 12 being fixed in fixed mount 20, guide pin 51 is the state that passes the first pin hole 14 of movable rotation-shaft 11 from bottom to top, and so guide pin 51 is with the circumferential position location of movable rotation-shaft 11; Then coaxial 13 is fixed in the travelling carriage 30, so obtains the first state shown in Figure 5, movable rotation-shaft 11 can't be reversed, be offset, simultaneously coaxial 13 fixing lower alignment activity rotating shaft 11 at travelling carriage 30 by 51 of guide pins are spacing under this first state.
On the basis of the first state, drive travelling carriage 30 and slide near movable rotation-shaft 11, so, coaxial 13 begins to be inserted in movable rotation-shaft 11.Owing to an interlinked mechanism 50 is arranged, so when driving travelling carriage 30 moved to right by the horizontal direction of arrow, guide pin 51 can by the vertical arrows direction synchronously towards lower slider, to such an extent as to begin to detach movable rotation-shaft 11, obtain the second state shown in Figure 6.In this second state, coaxial 13 beginning tight fit is inserted in movable rotation-shaft 11, so movable rotation-shaft 11 is subjected to coaxial 13, the Dual positioning of guide pin 51 simultaneously.The effect of interlinked mechanism 50 mainly is that the translation with travelling carriage 30 is converted into and drives guide pin 51 and vertically move, although the two can controlled independent driving, so can save a power source and control loop.Interlinked mechanism 50 can be realized with a lot of modes, especially, interlinked mechanism has mainly used a lever arm 52 in the present embodiment, this lever arm 52 is the metal material of rigidity, its two ends are matched with travelling carriage 30 and guide pin 51 with the rotating shaft activity respectively, and as seen, its structure is very simple, and cooperate precision, collisionless, noise is little, loss is also little, is specially adapted to high-speed motion.
On the basis of the second state shown in Figure 6, driving travelling carriage 30 continues to move to right, until coaxial 13 with movable rotation-shaft 11 complete in place alignment (being that the first pin hole 14 and the second pin hole 15 align among Fig. 3), at this moment, guide pin 51 has withdrawed from fully, obtains the third state as shown in Figure 7, under this state, can control pad mechanism 4 and carry out the work of pad, pin finally stably can be pressed into the first pin hole 14.
As seen, the mode that adopted travelling carriage 30 to cooperate with guide pin 51 has realized the accurately and rapidly location between movable rotation-shaft 11, coaxial and the pin, the contraposition of having avoided the problem such as unstable of movable rotation-shaft 11 to cause was fully lost efficacy, to such an extent as to affect the hidden danger of pad quality, make the pad operation become reliable and stable.Adopt interlinked mechanism 50, can drive simultaneously mutually vertical movable travelling carriage 30 and guide pin 51 with single power source, installation cost and complexity are reduced.
As can be seen from Fig. 3, fixed mount 20 is other to have a location block 21, and in coaxial 13 process of being inserted in movable rotation- shaft 11,21 pairs of main bodys of this position block 12 are carried out spacing, keep the axial restraint of movable rotation-shaft 11.This position block 21 is subject to the driving control of one second cylinder 62, can carry out spacing to the main body 12 of different size neatly.
Fig. 8 is the enlarged drawing of present embodiment pad head 4, with the signal of analysing and observe of sleeve 41 parts; Pad head 4 comprises:
One sleeve 41, its internal diameter is suitable with pin 19, and a side of these sleeve 41 walls is fixed a permanent magnet 43, and a permanent magnet wherein utmost point touches thimble 42 towards sleeve 41 inside, and another utmost point is towards the outside of sleeve 41; Sleeve 41 is fixed in a receiver 44; Thimble 42 axial sliding fits are fixed in a thimble seat 45 in sleeve 41.
Fig. 9 is right view embodiment illustrated in fig. 1, and pad head 40 has a rotation preventive mechanism 70, is used for preventing that pad head 40 from pressing down or retraction process spins, to such an extent as to affect the pin contraposition.Rotation preventive mechanism 70 has a spline arm 71, and this spline arm 71 is snug fit at pad mechanism 4 by a linear bearing 72 dead axles.The pad head can not rotated in a circumferential direction, and its attitude is more stable.
In addition, as shown in Figure 1, this pressure pin device also comprises an air nozzle 8, and this air nozzle 8 is towards the position of 4 pad mechanisms at movable rotation-shaft 11; Its effect is, pin 19 be completely fixed coaxial 13 with movable rotation-shaft 11 after, this air nozzle 8 is controlled to utilize pressure-air to blow off because chips that the pad action brings.
The above, it only is the utility model preferred embodiment, so can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
