Be equipped with two vertical limiting plates 11 of inside extension on the interior curb plate face of mounting panel 6, each limiting plate 11 is corresponding with a set of wind big gun, is located the intermediate position of each wind big gun of group on general, and when wind big gun subassembly 9 downwardly moving to extreme position, its connecting plate can contact with limiting plate 11 to stop wind big gun subassembly 9 and continue downstream, restriction wind big gun subassembly 9 descends the height, prevents that the wind big gun from compressing tightly the bolt excessively, guarantees the normal clear of dismantlement work.

The mounting plate 6 is also provided with a synchronous positioning mechanism 12 at a position below the mounting plate, and the synchronous positioning mechanism 12 is used for realizing accurate alignment of the wind cannon and the bolt.

Referring to fig. 3, fig. 3 is a schematic structural diagram of the synchronous positioning mechanism shown in fig. 1.

As shown in the figure, the synchronous positioning mechanism mainly comprises a synchronous positioning rod 13 and a third driving cylinder 14, wherein the third driving cylinder 14 is used for driving the synchronous positioning rod 13 to move to a position where the inner end (i.e. one end pointing to the mold) enters between two adjacent bolts of the mold or to exit between two adjacent bolts of the mold, and when a bolt located at the rear side (i.e. the opposite direction of the moving direction of the mold) of the two adjacent bolts moves to a position where the bolt contacts with the synchronous positioning rod 13 along with the mold, four wind cannons of the wind cannon assembly 9 are vertically aligned with four bolts on the mold within a screwing range.

Specifically, the cylinder body of the third driving cylinder 14 is fixed below the mounting plate 6 in a hanging manner through a first connecting plate 15, the telescopic rod of the third driving cylinder 14 points to the outside and is connected with a second connecting plate 16, the synchronous positioning rod 13 is parallel to the third driving cylinder 14, the moving direction of the synchronous positioning rod is perpendicular to the arrangement direction of the wind cannons, the inner end of the synchronous positioning rod 13 is in sliding fit with a through hole in the first connecting plate 15, and the outer end of the synchronous positioning rod is fixedly connected with the second connecting plate 16.

In order to ensure that the synchronous positioning rod 13 moves smoothly, a slide rod 17 is further arranged, the inner end of the slide rod 17 is fixedly connected with the first connecting plate 15, the outer end of the slide rod 17 is in sliding fit with the through hole on the second connecting plate 16, the slide rod 17 is positioned above the third driving cylinder 14, the synchronous positioning rod 13 is positioned below the third driving cylinder 14, the slide rod 17 and the synchronous positioning rod 13 are parallel to the axis of the third driving cylinder 14 and have the same distance with the axis of the third driving cylinder 14, that is, the slide rod 17 and the synchronous positioning rod 13 are arranged vertically and symmetrically by taking the axis of the third driving cylinder 14 as the center in terms of position. Of course, both may be arranged symmetrically in the front-rear direction with respect to the axis of the third drive cylinder 14.

When the telescopic rod of the third driving cylinder 14 extends outwards, the distance between the first connecting plate 15 and the second connecting plate 16 gradually becomes larger, the inner end of the synchronous positioning rod 13 retracts inwards relative to the first connecting plate 15, and the outer end of the slide rod 17 retracts inwards relative to the second connecting plate 16.

When the telescopic rod of the third driving cylinder 14 retracts inwards, the distance between the first connecting plate 15 and the second connecting plate 16 becomes smaller gradually, the inner end of the synchronous positioning rod 13 extends outwards relative to the first connecting plate 15, and the outer end of the sliding rod 17 extends outwards relative to the second connecting plate 16.

Although there are two synchronous positioning mechanisms 12 shown in the figure, it can be understood that the use requirement can be satisfied by only one synchronous positioning mechanism 12, and the two synchronous positioning mechanisms 12 are provided, on one hand, the precision of synchronous operation and alignment can be improved, and on the other hand, when one of the synchronous positioning mechanisms 12 fails, the other synchronous positioning mechanism 12 can still normally operate, thereby avoiding the phenomenon of operation interruption.

Furthermore, in the process of the continuous forward uniform movement of the mold, the bolts on the mold are screwed in a grouped manner, when screwing the last bolts of the mold, because the number of the remaining bolts may not be equal to the number of the wind cannons, for example, there are fourteen bolts on each side of the mold, and the number of the wind cannons of the wind cannon assembly is four, four groups of bolts on the mold are respectively screwed in four times, in the first three groups, the number of each group of bolts is four, and the number of the last group of bolts is two, that is, when screwing the last time, there are two bolts left at the position of the mold close to the tail end to be screwed, in this case, if there are two synchronous positioning mechanisms 12, the synchronous positioning rods 13 of the synchronous positioning mechanism 12 on the front side can be abutted against the last bolt, so as to perform synchronous positioning, the synchronous positioning mechanism 12 at the rear side will only perform the idle extension action and does not participate in the synchronous positioning because no bolt corresponds to the synchronous positioning mechanism.

In other embodiments, considering that the synchronous positioning rod 13 has a certain impact force when contacting with the bolt, the first connecting plate 15 is provided with a first sliding sleeve 18 at the through hole for sliding fit with the inner end of the synchronous positioning rod 13, and the second connecting plate 16 is provided with a second sliding sleeve 19 at the through hole for sliding fit with the outer end of the sliding rod 17. Can improve synchronous positioning rod 13's impact strength through setting up first sliding sleeve 18 and second sliding sleeve 19, avoid causing the pole body to buckle when contacting with the bolt, guarantee synchronous positioning rod 13's normal use.

When the device works, the two die bolt screwing machines 1 are symmetrically arranged at two sides of a die conveying channel, the die can move towards the same direction at a constant speed under the driving of the conveying mechanism, the time for the synchronous positioning rod 13 of the synchronous positioning mechanism 12 to extend towards the die can be set according to actual conditions, the synchronous positioning rod 13 extends out and then is positioned between two adjacent bolts, the bolt positioned at the rear side can be contacted with the synchronous positioning rod 13 along with the movement of the die, then the first driving cylinder 7 pushes the mounting plate 6 to synchronously move along the same direction with the die (the mounting plate 6 does not move before the bolt is contacted with the synchronous positioning rod 13), then the second driving cylinder 10 pushes the air cannon component 9 to descend to be matched with the bolt to carry out bolt screwing or unscrewing work, after the bolt is screwed or unscrewed, the third driving cylinder 14 drives the synchronous positioning rod 13 to retract, the second driving cylinder 10 drives the air cannon component 9 to upwards return to the original, the first driving cylinder 7 drives the mounting plate 6, the air cannon assembly 9 on the mounting plate and the synchronous positioning mechanism 12 to reset backwards together, and the operation of automatically screwing all bolts on the die can be completed by repeating the operation.

In order to reserve enough running time for each subsequent execution action, after the synchronous positioning rod 13 extends out, the synchronous positioning rod can be as close to the bolt positioned at the rear side as possible, namely, the distance between the synchronous positioning rod 13 and the front side bolt is larger than that between the synchronous positioning rod 13 and the rear side bolt at the moment of extending out, so that the time required by the rear side bolt to be contacted with the synchronous positioning rod is shortened as much as possible.

As shown in fig. 4, the wind big gun can set up radial movement's removal subassembly and axial pivoted runner assembly, removal subassembly and runner assembly play the effect of adjusting the wind big gun position, so that the wind big gun has certain activity, realize screwing up or the unscrewing to the bolt in certain error band, avoid causing wind big gun mechanism or bolt to damage, the spiro union sleeve 20 of wind big gun can set up the horn mouth 21 that plays the guide effect, if there is certain error, then can lead by the horn mouth.

The driving cylinder can be an oil cylinder or an air cylinder, and can also be replaced by a mode that a motor is driven by a gear rack mechanism; moreover, the bolt driving member may be a pneumatic screwing tool, i.e., a pneumatic gun, an electric screwing tool, a hydraulic driving screwing tool, or the like, and the bolt driving member drives the bolt to rotate in a forward direction or a direction mainly through continuous rotation, so that the purpose of loosening or screwing is achieved.

Alternatively, the third driving cylinder 14 may be arranged in the reverse direction, and the telescopic rod thereof may be directly used as the synchronization positioning rod 13, so that the synchronization positioning rod 13 and the slide bar 17 separately provided may be omitted, or the synchronization positioning rod 13 may be coaxially connected to the telescopic rod of the third driving cylinder 14 after the reverse arrangement, so that the slide bar 17 may be omitted. However, it should be noted that both of these ways are liable to cause direct impacts on the third driving cylinder 14, which can be effectively avoided by providing the parallel synchronizing jumper 13 and slide bar 17.

The above embodiments are merely preferred embodiments of the present invention, and are not limited thereto, and different embodiments can be obtained by performing targeted adjustment according to actual needs. For example, the synchronous positioning mechanism 12 is directly disposed at the lower portion of the mounting plate 6, or the extending and retracting direction of the synchronous positioning rod 13 is inclined at a certain angle relative to the arrangement direction of the wind cannons, or the synchronous positioning member is designed as a synchronous positioning plate, or the number of the wind cannons is reduced to three or increased to five, and so on. This is not illustrated here, since many implementations are possible.
