As shown in fig. 3,4, and 13 to 23, the limiting plate pressing device includes a first positioning tool 100, a pressing mechanism 200, a feeding mechanism 400, and a feeding manipulator 300.

As shown in fig. 13 to 19, the first positioning tool 100 includes a workbench 130, a first pushing mechanism 140 and a second pushing mechanism 150, the workbench 130 is provided with a first groove 131 penetrating up and down, the first groove 131 includes a first station area and a second station area, the workbench 130 is provided with a notch capable of exposing the compression end 106 of the limiting plate 102, the notch is communicated with the first groove 131, when the limiting plate 102 is placed in the first station area, the compression end 106 of the limiting plate 102 is exposed from the notch, the limiting plate 102 is in a free state, and the clamp spring 105 thereof is not deformed under pressure, as shown in fig. 15. The shape of the second station area is consistent with the shape of the groove 103 of the valve plate 101, and the clamp spring 105 of the limiting plate 102 in the second station area is deformed under pressure, so that the limiting plate 102 is pressed into the groove 103 of the valve plate 101 from the second station area. The shape of the first groove 131 is formed by overlapping the first station area and the second station area.

In this embodiment, the workbench 130 may be composed of a transverse plate and a vertical plate, and the transverse plate is provided with a first groove 131. When the limiting plate 102 is placed in the first station area, the right side and the front side of the pressing end 106 of the limiting plate 102 are exposed from the notch.

The first pushing mechanism 140 is used for pushing the pressing end 106 of the limiting plate 102 to drive the fastening end of the limiting plate 102 to move from the first station area to the second station area.

Specifically, the first pushing mechanism 140 includes a first telescopic cylinder 141 and a first push rod 142, where the first telescopic cylinder 141 is disposed on the workbench 130 by a bolt, one end of the first push rod 142 is connected with a piston rod of the first telescopic cylinder 141, for example, through a bolt connection, and the other end of the first push rod 142 can be abutted with a side surface of the compression end 106 away from the fastening end. The piston rod of the first telescopic cylinder 141 drives the first push rod 142 to linearly move, and thrust is applied to the rear side surface of the compression end 106 of the limiting plate 102; under the action of the pushing force, the limiting plate 102 moves from right to left, so that the buckling end of the limiting plate 102 moves from the first station area to the second station area, the side surface of the buckling end contacts with the wall surface of the first groove 131, and the clamping spring 105 also contacts with the wall surface of the first groove 131, namely the second positioning wall surface 133 but is not deformed, as shown in fig. 16.

The second pushing mechanism 150 is used for pushing the pressing end 106 of the limiting plate 102 to drive the pressing end 106 to move from the first station area to the second station area and deform the buckling end under compression.

Specifically, the second pushing mechanism 150 includes a second telescopic cylinder 151 and a second push rod 152, where the second telescopic cylinder 151 is disposed on the workbench 130 by a bolt, one end of the second push rod 152 is connected with a piston rod of the second telescopic cylinder 151, for example, through a bolt connection, and the other end of the second push rod 152 can be abutted with a side surface of the pressing end 106 away from the second station area. The piston rod of the second telescopic cylinder 151 drives the second push rod 152 to linearly move, and thrust is applied to the front side surface of the compression end 106 of the limiting plate 102; under the action of the pushing force, the pressing end 106 of the limiting plate 102 moves from front to back, so that the pressing end 106 is caused to swing from the first station area to the second station area, the rear side surface of the pressing end 106 is contacted with the first positioning wall surface 132, and the clamp spring 105 of the limiting plate 102 is caused to be deformed under the pressure of the second positioning wall surface 133, as shown in fig. 17.

In order to enhance the movement stability of the first push rod 142 and the second push rod 152, the table 130 may be provided with a guide hole, and the first push rod 142 and the second push rod 152 may be prevented from being greatly swayed when moving by the guide function of the guide hole. The cross-sectional shape of the first push rod 142 and the second push rod 152 is square.

In the present embodiment, the first push rod 142 and the second push rod 152 extend downward to form a protruding portion at an end near the limiting plate 102, so that the first push rod 142 and the second push rod 152 are L-shaped overall, and can apply a pushing force to the limiting plate 102, and an increase in the contact area between the first push rod 142 and the table 130 and an increase in the contact area between the second push rod 152 and the table 130 are avoided, resulting in an increase in friction force.

Of course, the first pushing mechanism 140 and the second pushing mechanism 150 may be a combination of a push rod, a link mechanism and a motor, or a combination of a push rod, a loop bar and a screw rod mechanism, as long as the push rod can move linearly.

The pressing mechanism 200 is disposed above the first positioning tool 100, and the pressing mechanism 200 is used for pushing the limiting plate 102 located in the second station area to move downward.

Specifically, the pressing mechanism 200 includes a first mounting seat 220, a first driving cylinder 210 and a pressing member 250, where the first driving cylinder 210 is disposed on the first mounting seat 220 by a bolt, and the first mounting seat 220 provides a supporting function for the first driving cylinder 210, and its shape can be set according to practical situations. The piston rod of the first driving cylinder 210 is connected to the pressing member 250, such as by a bolt. When the piston rod of the first driving cylinder 210 extends, the pressing member 250 moves downward, so that the limiting plate 102 can be pushed down into the groove 103 of the valve plate 101 from the second station area, and at this time, the second pushing mechanism 150 keeps applying pressure to the limiting plate 102, so that the limiting plate 102 is prevented from swinging due to the acting force between the clamping spring 105 and the second positioning wall 133, and the limiting plate 102 cannot be pressed into the groove 103 of the valve plate 101.

Of course, instead of using the first driving cylinder 210, a screw slider mechanism or other linear driving member may be used to drive the pressing member 250 upward or downward.

The pressing member 250 includes a pressing seat 255, a spring 252, and a pressing lever 251, and the pressing seat 255 is connected to a piston rod of the first driving cylinder 210, for example, by a bolt. The upper end of the spring 252 is connected to the pressing base 255, and the lower end of the spring 252 is connected to the pressing rod 251, for example, by welding or a snap-fit structure. The pressing seat 255 is connected with the first slider 230 through a bolt, the first installation seat 220 is provided with the first sliding rail 240, two ends of the first sliding rail 240 extend along the up-down direction, and the movement stability of the pressing seat 255 can be increased when the first driving cylinder 210 drives the pressing seat 255 to lift through the sliding connection of the first slider 230 and the first sliding rail 240.

In addition, the pressing seat 255 may be provided with a guide hole, and the upper end portion of the pressing rod 251 is inserted into the guide hole, so that the pressing rod 251 moves more stably in the up-down direction under the guiding action of the guide hole and the elastic force of the spring 252.

Because limiting plate 102 is thin slice special-shaped part, warp easily, set up spring 252 between pushing down seat 255 and pushing down the depression bar 251, when pushing down the depression bar 251 to limiting plate 102, spring 252 can play the cushioning effect, avoids limiting plate 102 to warp the damage because of too big pushing down effort. In the present embodiment, only one pressing bar 251 is shown, and two or more pressing bars 251 may be provided according to actual circumstances.

In other embodiments, three pressing rods 251 are provided, and downward pushing forces are applied to the buckling end, the clamping spring 105 and the pressing end 106 of the limiting plate 102 respectively.

When the pressing mechanism 200 works, the top surface of the valve plate 101 is attached to the horizontal bottom surface of the workbench 130, the horizontal projection of the groove 103 of the valve plate 101 is overlapped with the second station area of the first groove 131 of the workbench 130, so that the clamp spring 105 is always in a pressed deformation state in the process of moving the limiting plate 102 downwards from the second station area to the groove 103, and the limiting plate 102 is clamped in the groove 103.

Further, the pressing component 250 further includes a second driving cylinder 254 and a limiting rod 253, the second driving cylinder 254 is disposed on the pressing seat 255 through a bolt, the upper end of the limiting rod 253 is connected with a piston rod of the second driving cylinder 254, for example, through a fastening structure or a bolt connection, and the lower end of the limiting rod 253 can be abutted against the workbench 130.

Since the second driving cylinder 254 is disposed on the pressing base 255, when the pressing rod 251 applies a downward force to the limiting plate 102, the second driving cylinder moves together with the pressing base 255. When the limiting rod 253 is abutted against the top surface of the workbench 130, a certain mechanical limiting effect can be achieved on the pressing seat 255, and the limiting plate 102 is prevented from being crushed due to the fact that the pressing rod 251 moves down too far. The second driving cylinder 254 extends through the piston rod thereof, drives the limiting rod 253 to move downwards, and can adjust the downward movement stroke of the pressing rod 251.

As shown in fig. 14, further, the first positioning fixture 100 further includes a lifting mechanism. The lifting mechanism has a fixed end and a movable end, and the movable end is connected to the workbench 130 to drive the workbench 130 to move up and down. Specifically, the lifting mechanism comprises a fixing seat 110 and a lifting cylinder 120, the lifting cylinder 120 is arranged on the fixing seat 110 through bolts, and the fixing seat 110 plays a supporting role on the lifting cylinder 120.

Of course, the lifting mechanism may also adopt a screw rod sliding block mechanism or other linear driving members, and only needs to lift the workbench 130.

In other embodiments, the first positioning fixture 100 is not provided with a lifting mechanism, but a lifting mechanism is provided on the station base, for example, a telescopic cylinder drives the station base to lift, so that the station base can contact with the workbench 130.

The length direction of the stopper plate 102 coincides with the length direction of the feed rail 430.

And, the feeding track 430 is provided with a limiting piece, and the limiting piece can be contacted with the top surface of the limiting plate 102, so that the limiting plates 102 can not move orderly due to the overlapping between two adjacent limiting plates 102.
