Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 4, proposing an embodiment of the locking nut anti-loose structure of injection moulding machine mode-locking oil cylinder of the present utility model, is the locking nut locking structure be applied on injection moulding machine mode-locking oil cylinder, comprises crosshead 2 and locking nut 1.The end face relative with locking nut 1 of crosshead 2 is provided with by certain angle and position the screwed hole 21 distributed around circular hole, axially mill out the square groove 11 corresponding to screwed hole 21 in the outside wall surface of locking nut 1 simultaneously, load onto in the process that piston rod 5 tightens at locking nut 1, screwed hole 21 and square groove 11 align, slightly adjust after tightening like this and just can load onto screw 3 in the screwed hole 21 of alignment and square groove 11, thus reach the locking object of shearing.
And, locking nut 1 is made notch 12 at radial direction fluting, makes out limit nut, the end face of locking nut 1 arranges the screw 13 axially running through notch 12, in the screw 13 opening limit nut, loads onto screw 4, the object that friction is locking after tightening like this, can be played.
Being arranged on square groove 11 in the present embodiment with the screw 3 of screwed hole 21 is grub screw 3, and the screw 4 be arranged in screw 13 is hexagonal socket head cap screw 4.
Screwed hole 21 in the present embodiment is provided with 8, and square groove 11 is provided with 8.As Fig. 2, shown in 3, screwed hole 21 is distributed in on the circle that is the center of circle of the center of circle of the circular hole of crosshead 2 end face, and be that a component becomes two groups of arrangements with 4, the central angle that the center of circle of the screwed hole 21 be often connected in group is formed to the round center of circle is 20 °, wherein the screwed hole 21 being placed in end of a group is positioned on round vertical symmetry axis, angle between the connecting line in the center of circle to the center of circle of circle of the screwed hole 21 being placed in end of another group and the vertical symmetry axis of circle is 10 °, central angle between the screwed hole 21 of one opposite end of two groups is 130 °, central angle between the screwed hole 21 of another opposite end is 110 °.Square groove 11 is uniformly distributed around the central shaft of locking nut 1, and the angle between the center line of the square groove 11 that is connected is 45 °.
As shown in Figure 4, load onto in the process that piston rod 5 tightens at locking nut 1,8 screwed holes 21 and 8 square grooves 11 locking nut 1 often tighten advance 0.05mm just have a screwed hole 21 and square groove 11 just on, slightly adjust after tightening like this and just can load onto grub screw 3, reach and shear locking object.In the screw 13 of locking nut 1, load onto hexagonal socket head cap screw 4 to tighten simultaneously, the object that friction is locking can be played.Whole installation process is simple to operate, easy and convenient.
Through the results show repeatedly, this kind of injection moulding machine mode-locking oil cylinder locking nut new construction can prevent from getting loose in locking nut 1 course of work completely, and installation process is simple to operate, easy and convenient.
Traditional locking nut and universal locking nut combine by the utility model, get both advantages, the shortcoming overcoming both designs, not only can realize traditional locking nut structure simple, advantage easy for installation, and the advantage that can realize that universal locking nut 1 under any circumstance can play locking effect.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
