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 region and a second station region, the workbench 130 is provided with a notch capable of exposing the pressing 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 region, the pressing end 106 of the limiting plate 102 is exposed from the notch, the limiting plate 102 is in a free state, and the snap spring 105 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 snap spring 105 of the limiting plate 102 located in the second station area deforms 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 working platform 130 may be composed of a horizontal plate and a vertical plate, and the horizontal plate is provided with a first groove 131. When the retainer plate 102 is placed in the first station area, the right and front sides of the pressing end 106 of the retainer plate 102 are exposed from the notch.

The first pushing mechanism 140 is used for pushing the pressing end 106 of the position limiting plate 102 to drive the buckling end of the position 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, the first telescopic cylinder 141 is disposed on the workbench 130 through a bolt, one end of the first push rod 142 is connected to a piston rod of the first telescopic cylinder 141, for example, through a bolt, and the other end of the first push rod 142 can abut against a side surface of the pressing end 106 far away from the fastening end. The piston rod of the first telescopic cylinder 141 drives the first push rod 142 to move linearly, and thrust is applied to the rear side face of the pressing end 106 of the limiting plate 102; under the pushing force, the position-limiting plate 102 moves from right to left, so that the fastening end of the position-limiting plate 102 moves from the first station area to the second station area, the side surface of the fastening end contacts with the wall surface of the first groove 131, and the clamp spring 105 also contacts with the wall surface of the first groove 131, i.e., 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 so as to drive the pressing end 106 to move from the first station area to the second station area and to deform the fastening end under pressure.

Specifically, the second pushing mechanism 150 includes a second telescopic cylinder 151 and a second push rod 152, the second telescopic cylinder 151 is disposed on the working table 130 through a bolt, one end of the second push rod 152 is connected to a piston rod of the second telescopic cylinder 151, for example, through a bolt, and the other end of the second push rod 152 can abut against a side surface of the pressing end 106 away from the second station area. A piston rod of the second telescopic cylinder 151 drives the second push rod 152 to move linearly, so that thrust is applied to the front side surface of the pressing end 106 of the limiting plate 102; under the pushing force, the pressing end 106 of the stopper plate 102 moves from front to back, so that the pressing end 106 swings from the first station area to the second station area, and the rear side surface of the pressing end 106 contacts with the first positioning wall surface 132, so that the snap spring 105 of the stopper plate 102 is deformed by the pressure of the second positioning wall surface 133, as shown in fig. 17.

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

In this embodiment, the first push rod 142 and the second push rod 152 extend downward to form a protrusion at an end close to the position-limiting plate 102, so that the first push rod 142 and the second push rod 152 are L-shaped as a whole, and can apply a pushing force to the position-limiting plate 102, and avoid an increase in friction force due to an increase in a contact area between the first push rod 142 and the workbench 130 and an increase in a contact area between the second push rod 152 and the workbench 130.

Of course, the first pushing mechanism 140 and the second pushing mechanism 150 may also adopt 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 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 configured to push the limiting plate 102 located in the second station area to move down.

Specifically, the pressing mechanism 200 includes a first mounting seat 220, a first driving cylinder 210 and a pressing member 250, the first driving cylinder 210 is disposed on the first mounting seat 220 through a bolt, and the first mounting seat 220 provides a supporting function for the first driving cylinder 210, and the shape of the first driving cylinder can be set according to actual conditions. The piston rod of the first drive cylinder 210 is connected to the hold-down member 250, such as by a bolt. When the piston rod of the first driving cylinder 210 extends, the pressing member 250 moves downward, and the limiting plate 102 can be pushed downward into the groove 103 of the valve plate 101 from the second station area, at this time, the second pushing mechanism 150 keeps applying pressure to the limiting plate 102, and the situation that the limiting plate 102 cannot be pressed into the groove 103 of the valve plate 101 due to the fact that the limiting plate 102 swings due to the acting force between the clamp spring 105 and the second positioning wall surface 133 is avoided.

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 to move up or down.

The depressing member 250 includes a depressing seat 255, a spring 252, and a depressing rod 251, and the depressing seat 255 is connected with the piston rod of the first driving cylinder 210, for example, by a bolt. The upper end of the spring 252 is connected to the lower holder 255, and the lower end of the spring 252 is connected to the lower pressing bar 251, for example, by welding or a snap structure. The lower pressing base 255 is connected with the first sliding block 230 through a bolt, the first mounting base 220 is provided with a first sliding rail 240, two ends of the first sliding rail 240 extend along the vertical direction, and the first sliding block 230 is connected with the first sliding rail 240 in a sliding manner, so that the movement stability of the lower pressing base 255 can be improved when the first driving air cylinder 210 drives the lower pressing base 255 to lift.

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

Because the limiting plate 102 is a sheet special-shaped part and is easy to deform, the spring 252 is arranged between the pressing seat 255 and the pressing rod 251, and when the pressing rod 251 presses the limiting plate 102 downwards, the spring 252 can play a buffering role, so that the limiting plate 102 is prevented from being deformed and damaged due to excessive pressing acting force. In the present embodiment, only one pressing bar 251 is shown, and two or more pressing bars 251 may be provided according to actual conditions.

In other embodiments, three pressing rods 251 are provided to apply downward pushing force to the fastening end of the limiting plate 102, the clamp spring 105 and the pressing end 106.

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 limiting plate 102 is always in a pressed and deformed state in the process of moving downwards to the groove 103 from the second station area, and the limiting plate 102 is clamped in the groove 103.

Further, the pressing component 250 further comprises a second driving cylinder 254 and a limiting rod 253, the second driving cylinder 254 is arranged on the pressing base 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 buckling structure or a bolt connection, and the lower end of the limiting rod 253 can be abutted to the workbench 130.

Since the second driving cylinder 254 is provided on the pressing base 255, when the pressing rod 251 applies a downward force to the stopper plate 102, it moves together with the pressing base 255. When the limiting rod 253 abuts 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 by the pressing rod 251 due to overlarge downward moving distance. The second driving cylinder 254 extends through its piston rod to drive the stopper 253 to move downward, so as to adjust the downward movement stroke of the downward pressing rod 251.

As shown in fig. 14, further, the first positioning tool 100 further includes a lifting mechanism. The lifting mechanism has a fixed end and a movable end, and the movable end is connected with the worktable 130 to drive the worktable 130 to move up and down. Specifically, the lifting mechanism includes a fixing base 110 and a lifting cylinder 120, the lifting cylinder 120 is disposed on the fixing base 110 through a bolt, and the fixing base 110 supports the lifting cylinder 120. The piston rod of the lifting cylinder 120 can extend and retract along the up-down direction, the piston rod is connected with the workbench 130, the workbench 130 is connected with the fixed seat 110 through a slider sliding rail structure, and the workbench 130 can slide up and down relative to the fixed seat 110.

The piston rod of the lifting cylinder 120 is shortened to drive the workbench 130 to move downwards, so that the workbench 130 is in contact with the valve plate 101 located on the limiting plate station seat 913, and the limiting plate 102 is favorably pressed into the groove 103 of the valve plate 101.

Of course, the lifting mechanism may also be a screw-slider mechanism or other linear driving member, and only needs to be able to lift the worktable 130.

In other embodiments, the first positioning tool 100 does not have a lifting mechanism, and a lifting mechanism is provided at the station seat, for example, a telescopic cylinder is used to lift the station seat, so that the station seat can contact with the workbench 130.

As shown in fig. 13, 22 and 23, the feeding mechanism 400 is provided with an ejection station of the limiting plate 102, and the feeding manipulator 300 is disposed above the ejection station and can transfer the limiting plate 102 from the ejection station to the first station area, so that automatic feeding of the limiting plate 102 is realized, and the limiting plate 102 does not need to be manually placed in the first station area.

The feeding mechanism 400 includes a vibration plate 410, a linear vibrator 420, and a feeding rail 430. The feeding rail 430 is horizontally disposed, one end of the feeding rail 430 is connected to the discharge port of the vibration plate 410, and the other end of the feeding rail 430 is a discharge station, so that the limiting plate 102 on the feeding rail 430 moves horizontally.

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

In addition, the feeding rail 430 is provided with a limiting member, and the limiting member can contact with the top surface of the limiting plate 102, so as to prevent the limiting plates 102 from being orderly moved due to overlapping between two adjacent limiting plates 102. The limiting member may be a limiting rod or a limiting sheet, for example, the height distance between the limiting rod and the bottom surface of the feeding track 430 is slightly greater than the thickness of the limiting plate 102, and the length direction of the limiting rod is consistent with the length direction of the feeding track 430.
