Description

Telescopic damping positioner

Technical field

The utility model relates to positioner, particularly steel pipe is carried out the telescopic damping positioner that axial location is used.

Background technology

As shown in Figure 1, have at present in the steel tube factory positioner 1a is installed on many stations, this positioner major function is that steel pipe 2a is carried out axial location, be that steel pipe 2a advances under the axial driving of V-type conveying roller 4a, because positioner 1a realizes the location, vertically be transplanted on next station by stepping feeding beam 3a then and realize finishing steps such as cutting thread or chamfering.Shown in Fig. 2 a and Fig. 2 b, this positioner 1a mainly is made up of baffle plate 11a and bakelite backing plate 12a, is fixed together by screw 13a between the two.Bakelite backing plate 12a can change, and in the production use, mainly there is following defect problem in this positioner 1a:

1) positioning accuracy is low, causes later process crudy instability.In process of production, steel pipe 2a V-type roller 4a carry advance strike positioner 1a after, form bounce-back easily, be that steel pipe 2a retreats vertically, the steel pipe 2a amount of retreating of different size is inconsistent, cause and regulate difficulty, thereby it is low to form positioning accuracy, precision quality just can't be stablized in the later process processing like this;

2) bakelite backing plate 12a damages easily.Steel pipe 2a carries by V-type roller 4a and advances rigid impact on positioner 1a, and the end face impulsive force of steel pipe 2a often breaks the bakelite backing plate 12a of positioner 1a, and bakelite backing plate life cycle is short;

3) form fault, damage equipment and tube material easily.In the production use, when bakelite backing plate 12a damages, the middle part forms a pit, the steel pipe 2a in perhaps producing more in short-term, steel pipe is behind the location, the steel pipe positioning end contacts (perhaps being absorbed in the pit of bakelite backing plate 12a) with the surface of positioner 1a, when step rate 3a rose steel pipe 2a picking-up rising, steel pipe one end was subjected to downward resistance, must cause steel pipe to tilt to an end, thereby the fault of causing causes corresponding damage (see figure 3).

Summary of the invention

The purpose of this utility model is a kind of new telescopic damping positioner of design, improve the positioning accuracy in the steel pipe processing, guarantee product processing quality, improve the spare part service life of positioner simultaneously, avoid the generation of accident, to solve the defective that original positioner exists.

For achieving the above object, the utility model provides a kind of telescopic damping positioner, comprise baffle plate, be fixed to the bakelite backing plate on the baffle plate, wherein, this device also comprises frame, and it is the U type frame structure of left opening, have last stop surface, lower support face and back installed surface, last stop surface extends a stopper section downward vertically near an end of opening, and the baffle plate lower hinge is on the lower support face, and baffle plate top backstop is in the medial surface of stopper section; Leather bag, it is positioned at frame, and an end is connected on the baffle plate middle part, and the other end is a screw thread tracheae, and this screw thread tracheae passes the back installed surface of frame and fixes; Spring, it is positioned at frame, and an end is connected in baffle plate top, and the other end is fixed on the back installed surface of frame.

Above-mentioned positioner also comprises compressed air control system, and this system links by the screw thread tracheae of tracheae and leather bag; This compressed air control system comprises a reversal valve; Described leather bag is one, and its two ends are fixed on respectively on frame and the baffle plate; Upwards protrude out two spaced apart back-up blocks with interstitial hole on the lower support face of above-mentioned frame, described baffle plate bottom is fixed by the interstitial hole that bearing pin passes two back-up blocks.

Advantage of the present utility model is: because the setting of leather bag and spring; played the effect of vibration reduction and cushioning; avoided impact failure to the bakelite backing plate; also avoid simultaneously the bounce-back of steel pipe, improved the positioning accuracy of steel pipe, avoided the generation of accident simultaneously; reduced equipment downtime; improve the service life of part of appliance, guaranteed product processing quality, increased productivity effect.

The specific embodiment

Shown in Fig. 4 a, 4b, in a preferred embodiment of the present utility model, a kind of telescopic vibration damping positioner 100 is provided, its primary structure is made up of frame 1, baffle plate 2, bakelite backing plate 3, bearing pin 4, three leather bags 5, spring 6, screw 7, nut 8 etc., wherein, baffle plate 2 is a steel plate, and its surface design has four screwed holes 21, is used for by screw 7 bakelite backing plate 3 being fixed in baffle plate 2; Baffle plate 2 lower ends are provided with an outstanding axis hole 22.Frame 1 is the U type framework of left opening, and it plays the fixing effect of benchmark, and it has back installed surface 11, lower support face 12 and last stop surface 13, and back installed surface 11 is a plane, and the center design on this plane has a tapped through hole 111; Be arranged at intervals with two back-up blocks 121 near opening 14 places, a frame left side along opening direction on the lower support face 12, these two back-up blocks 121 form from make progress vertical projection of lower support face 12, each back-up block is provided with supported hole 122, these two supported holes 122 are aimed at the axis hole 22 of baffle plate 2 lower ends, pass successively wherein by bearing pin 4 baffle plate 2 is movably connected on the frame 1, bearing pin 4 drives baffle plates 2 and can rotate around bearing pin 4 frame 1 in; Last stop surface 13 is the plane, and the front side edge on plane is along being extended with stopper section 131 downward vertically, realizes spacing when baffle plate 2 stretches out, the perpendicularity of baffle plate 2 when guaranteeing the location; One end of leather bag 5 is fixed on the baffle plate 2, and the other end has screw thread tracheae 51, and the screw thread tracheae 51 of the leather bag 5 of close back installed surface 11 passes the tapped through hole 111 on the frame 1 back installed surface 11, and is fixing with nut 8 then.One end of spring 6 is connected in baffle plate 2 tops, and the other end is fixed on the back installed surface 11 of frame 1, and when leather bag 5 inflation, leather bag 5 promotes baffle plates 2 and stretches out and lean against on the inboard of stopper section 131 of frame 1; When leather bag 5 exhausts, spring 6 drives baffle plate 2 and withdraws automatically, and like this, the bakelite backing plate 3 that is fixed on the baffle plate 2 can stretch out under the effect of leather bag 5 and spring 6 or withdraw together.

As Fig. 5 a, shown in the 5b, in use, as long as telescopic vibration damping positioner 100 is installed in the front of V-type conveying roller 200, frame 1 is fixing, and compressed air control system 300 is linked in the screw thread tracheae 51 of leather bag 5, in producing use, telescopic vibration damping positioner 100 control valve 301 when electric, leather bag 5 inflations, baffle plate 2 stretches out, V-type conveying roller 200 is transported to steel pipe 400 to locate on the positioner (sees Fig. 5 a), though this moment, steel pipe 400 directly impinged upon on the baffle plate 2,, reached the effect of vibration reduction and cushioning owing to there are leather bag 5 inflations to have compressibility, avoided impact failure, also avoided the bounce-back of steel pipe 400 simultaneously bakelite backing plate 3; After finish the location, control valve 301 outages, compressed air in the leather bag 5 releases, baffle plate 2 is withdrawn under the effect of spring force, the baffle plate 2 of positioner 100 breaks away from come (seeing Fig. 5 b) fully with the end face of steel pipe 400 at this moment, like this when step rate 500 liftings delivery steel pipe 400 during to next station, the accident that forms with regard to the obstruction of having avoided 2 pairs of steel pipes 400 of baffle plate.
