Description
Technical field
The utility model relates to a kind of connection set that is used for oil hydraulic cylinder, a kind of oil hydraulic cylinder bolt-type connection set that carries out position probing of saying so more specifically.
Background technique
In the hydraulic transmission field, oil hydraulic cylinder when it is connected with the external movement component, needs Placement reliably, simply and fast as a requisite element, should possess the position detecting function of its hydraulic cylinder piston rod or latch simultaneously.In the actual using process of oil hydraulic cylinder, most of outside component require and can only translation can not axially rotate.Existing Placement mainly is threaded, and promptly the screw thread through hydraulic cylinder piston rod directly is connected with exterior part, on Placement, also exceptionally is threaded and two kinds of forms of internal thread.The screw thread of this kind structure is easy to generate the stress concentration phenomenon; Strengthened the installation, maintenance difficulty in narrow and small place, certain operations space; If connected exterior part is heavier and when adopting cantilever structure; The piston rod of oil hydraulic cylinder directly is connected meeting with it oil hydraulic cylinder itself is caused damage, and externally component do not have and can drive piston rod under the situation of guide rail yet and rotate simultaneously, make it not reach the requirement of exterior part translation.And the also mechanical stroke switches that adopt of the position detecting function on the existing oil hydraulic cylinder linkage structure are realized more, because that it is applied in this performance is unreliable, and the deviation that causes higher level's control system to read easily.
The model utility content
The purpose of the utility model is to solve above-mentioned deficiency, and a kind of extruding force that produces when bearing cantilever structure and a kind of oil hydraulic cylinder bolt-type connection set that carries out position probing of flexural stress are provided.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of oil hydraulic cylinder bolt-type connection set that carries out position probing that the utility model provided; Comprise oil hydraulic cylinder, described connection set also comprises sleeve and latch, and an end and the sleeve of oil hydraulic cylinder interfix; And the two ends of sleeve are provided with fixing device; A latch part gets into the inside of sleeve, and the piston rod end of oil hydraulic cylinder contacts with latch or directly inserts latch, and flexibly connects through straight pin and latch; Also be equipped with on the described sleeve near switch.
Further technological scheme is: described latch is flat, and its any side external surface also is provided with a plane.
Technological scheme further is: the end that described latch is connected with piston rod is flat stepped.
Technological scheme further is: described latch is a flat stair-stepping end by the spacing engaging of Cock screw that is fixed on the sleeve, and the plane that the latch outer surface is provided with is corresponding with the position of Cock screw.
Technological scheme further is: the fixing device at described sleeve two ends is attachment screws.
Technological scheme further is: describedly be installed on the sleeve through cover plate near switch.
Technological scheme further is: described cover plate passes through screw in cartridges sides.
Compared with prior art; The beneficial effect of the utility model is: through adopting sleeve the linkage structure of hydraulic cylinder piston boom end is protected, made oil hydraulic cylinder when being connected with the exterior part of cantilever structure, can be used for supporting be squeezed power and flexural stress, the piston rod of protection oil hydraulic cylinder is not hit; That on sleeve, installs simultaneously is used to two location statuss detecting the insertion of latch and extract near switch; And with its detected data-signal to higher level's control system transmission, and a kind of oil hydraulic cylinder bolt-type connection set that carries out position probing that the utility model provided, compact structure; Bearing load is big; Easy for installation, remote controlled, can extensively should be in rocket gun car launcher, ECM antenna car, radar antenna car, civil engineering car and nonstandard product; Be used for moving elements such as launcher, antenna, lifting structure are carried out mechanical caging, application area is wide.

Fig. 3 is the B-B sectional view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
Fig. 1 is the overall structure schematic representation of the utility model.
A kind of oil hydraulic cylinder bolt-type connection set that carries out position probing as shown in Figure 1, that the utility model provided comprises oil hydraulic cylinder 1; Described connection set also comprises sleeve 2 and latch 3, and an end and the sleeve 2 of oil hydraulic cylinder 1 interfix, and the two ends of sleeve 2 are provided with fixing device; Latch 3 parts get into the inside of sleeve 2, and latch 3 is inserted in piston rod 4 ends of oil hydraulic cylinder 1, and piston rod 4 also can only contact with an end of latch 3 simultaneously; And they flexibly connect through straight pin 9 and latch 3; In conjunction with shown in Figure 3, Fig. 3 is the B-B sectional view of Fig. 1, and piston rod 4 ends and latch 3 are radially fixing through straight pin 9; On the Placement for piston rod 4 and latch 3, piston rod 4 inserts latches 3 inside or only contacts with an end of latch 3, all can realize identical technique effect.
For the shape of above-mentioned latch 3, comparatively preferred scheme is that it is set to flat and in use rotates to prevent it, and its with an end of piston rod 4 flexible connections on the stair-stepping structure of one deck at least is set.On the technological means that prevents its rotation; The technological scheme that is more preferably is that the outer surface at latch 3 is provided with a plane; Through being fixed on the Cock screw 6 spacing engagings on the sleeve 2, and the position on Cock screw 6 and this plane is to corresponding, with further reinforcement latch 3 mounting stability; Also further avoid rotating in actual use, improve the accuracy of position probing simultaneously.
Shown in Fig. 1-2, the oil hydraulic cylinder bolt-type connection set of above-mentioned carried out position probing, the fixing device at sleeve 2 two ends can be for having the device of fixation arbitrarily, and what adopted in this mode of execution is attachment screw.And be the function that realizes its position probing; Also need on sleeve 2, also to install near switch 5, its preferred mounting type is for to be installed on the sleeve 2 through cover plate 7, and cover plate 7 adopts the side of screw at sleeve 2; Preferably be set to two near switch 5; One is normally off, and another is a normally open, is respectively applied for the insertion that detects latch 3 and puts in place and extract two location statuss that put in place; And the stroke of latch 3 can confirm that latch 3 strokes that the inventor of the utility model is adopted are 0 to 40 millimeter according to the size of device in experiment.The end that above-mentioned latch 3 is connected with piston rod 4 is provided with stair-stepping another purpose for ease of detect the state of latch 3 near switch 5.
And above-mentioned latch 3 flexibly connects through straight pin 9 and piston rod 4; Adopted the surplus drive fit between straight pin 9 and the latch 3,9 of piston rod 4 and latch 3 and straight pins are big Spielpassung, so when latch 3 bears radial load under stressed situation; Make latch 3 distortion backs only power passed to sleeve 2; Thereby guaranteed that piston rod 4 does not receive radial load, improved the stability that oil hydraulic cylinder uses, made that the utility model especially suits in cantilever beam structure, to install and use.
The utility model in actual use, the attachment screw 8 that only need take sleeve 2 the other ends apart is tightened in sleeve 2 on other carrier and gets final product, for example cantilever structure; Simultaneously for ease of detect the position of latches 3 near switch 5, the special one-tenth of an end of latch 3 is stepped, when latch 3 is inserted into; Detecting less than metal near switch of normally off provides the latch signal that puts in place, when latch 3 pulls out when putting in place; Normally open detect metal near switch, provide the signal that puts in place of pulling pin.
