[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model discloses an automated feeding device for a shearing machine.

[0032] Example 1

[0033] Reference Figure 1-6 An automated feeding device for a shearing machine includes a base 1, a rotating rod 2 rotatably connected to the upper surface of the base 1, a rotating table 3 fixedly connected to the upper surface of the rotating rod 2, an L-shaped plate 6 fixedly connected to the upper surface of the base 1, a hydraulic shearing machine 7 fixedly connected to the lower surface of the L-shaped plate 6, and a driving mechanism provided on the upper surface of the base 1. The rotating rod 2 rotates through the driving mechanism, which includes a motor 8, a first bevel gear 9, and a second bevel gear 10. The motor 8 is fixedly connected to the upper surface of the base 1, the first bevel gear 9 is fixedly sleeved on the output end of the motor 8, and the second bevel gear 10 is fixedly connected to the outer surface of the rotating rod 2 and meshes with the first bevel gear 9.

[0034] Start the motor 8 to make the first bevel gear 9 rotate, which in turn drives the second bevel gear 10 to rotate, thereby allowing the rotating rod 2 to rotate. Since the rotating rod 2 is fixedly connected to the rotating platform 3, the rotating platform 3 will rotate with the rotating rod 2.

[0035] Reference Figure 1-2 and Figure 4-6The upper surface of the rotating platform 3 has multiple placement holes, and a placement platform 4 is slidably disposed inside each placement hole. Each placement platform 4 has a fixing mechanism inside, which includes multiple cylinders 11, multiple first trapezoidal blocks 12, multiple second trapezoidal blocks 13, multiple T-shaped blocks 14, and multiple clamping plates 15. The upper surface of each placement platform 4 has two grooves symmetrically formed, and a sliding hole is formed between the two corresponding grooves. Each first trapezoidal block 12 is symmetrically slidably disposed inside the corresponding sliding hole. Each clamping plate 15 is fixedly connected to one end of the corresponding first trapezoidal block 12. The inclined surface of each first trapezoidal block 12 has a T-shaped groove. Each T-shaped block 14 is slidably disposed inside the corresponding T-shaped groove. Each second trapezoidal block 13 is fixedly connected between the two corresponding T-shaped blocks 14. The lower surface of each sliding hole has a placement groove. Each cylinder 11 is fixedly connected inside the corresponding placement groove. The output end of each cylinder 11 is fixedly connected to the lower surface of the corresponding second trapezoidal block 13.

[0036] The workpiece is placed on the upper surface of the placement table 4, and then the cylinder 11 is activated, which causes each second trapezoidal block 13 to move down. Then, by sliding the T-shaped block 14, the corresponding two first trapezoidal blocks 12 can move closer to each other, so that the two clamping plates 15 can clamp the workpiece and prevent the workpiece from shaking during the shearing process. Then, by rotating the rotating table 3, the workpiece can be automatically sent to the hydraulic shearing machine 7, preventing the operator from directly contacting the hydraulic shearing machine 7, thereby preventing the occurrence of danger.

[0037] Reference Figure 1-3 Each placement platform 4 has a movable plate 5 fixedly connected to its lower surface. The base 1 has an internal cavity containing an adjustment mechanism. The movable plate 5 moves via this mechanism, which includes a lead screw 16, a sliding plate 17, two connecting blocks 18, and a rotating plate 19. The lead screw 16 is rotatably connected to the inside of the cavity. The sliding plate 17 is threaded onto the wall of the lead screw 16. The two connecting blocks 18 are symmetrically fixedly connected to the lower surfaces of the two sliding plates 17. One end of each connecting block 18 penetrates the lower surface of the cavity and is fixedly connected to the upper surface of the movable plate 5. The upper end of the lead screw 16 penetrates the upper surface of the cavity. The rotating plate 19 is fixedly connected to the upper surface of the lead screw 16. At the end, a limiting mechanism is provided above the rotating platform 3. The limiting mechanism is matched with the adjustment mechanism. The limiting mechanism includes a fixed frame 20, a plug rod 21, a spring 22, a stop block 23 and a pull ring 24. The fixed frame 20 is fixedly connected to the upper surface of the rotating plate 19. The upper end of the rotating plate 19 is provided with a plug hole. The plug rod 21 is set inside the fixed frame 20 and slidably sleeved inside the plug hole. The stop block 23 is fixedly sleeved on the rod wall of the plug rod 21. The spring 22 is slidably sleeved on the rod wall of the plug rod 21. The upper end of the plug rod 21 is fixed to the upper surface of the fixed frame 20 and fixedly connected to the pull ring 24. Multiple slots are provided around the upper surface of the base 1. Each slot matches the corresponding plug rod 21.

[0038] To adapt the device to workpieces of different heights, pull the pull ring 24 to move the insertion rod 21 out of the slot. Then, rotate the rotating plate 19, which will drive the lead screw 16 to rotate, thereby allowing the slide plate 17 to move up and down. Then, through the connection of the two connecting blocks 18, the moving plate 5 can move up and down, and then the placement platform 4 can move up and down so that the tail of the workpiece of different heights can be flush with the upper surface of the rotating platform 4.

[0039] Example 2

[0040] Based on Example 1, referring to Figure 1 The hydraulic shearing machine 7 is attached to the upper surface of the rotating table 3.

[0041] Because the hydraulic scissor 7 fits snugly against the upper surface of the rotating table 3, more of the tailstock can be removed to facilitate subsequent grinding.

[0042] Example 3

[0043] Based on Example 1, referring to Figure 1 The lower surface of the movable plate 5 has a strip-shaped hole that matches the motor 8.

[0044] The use of the slotted holes ensures that the moving plate 5 is not blocked by the motor 8 when it moves downward, thus allowing the moving plate 5 to move normally.

[0045] Example 4

[0046] Based on Example 1, referring to Figure 1 The upper surface of the slide plate 17 has an internal threaded hole that matches the lead screw 16.

[0047] The internal threaded hole allows the slide plate 17 to be easily threaded onto the wall of the corresponding lead screw 16.

[0048] Example 5

[0049] Based on Example 1, referring to Figure 1 and Figure 3 Each sliding hole has a limiting groove on its upper surface, and two limiting blocks 25 are slidably arranged inside each limiting groove. Each limiting block 25 is fixedly connected to the upper surface of the corresponding first trapezoidal block 12.

[0050] Each limiting block 25 can be used to make each first trapezoidal block 12 move stably and prevent it from sliding out of the corresponding sliding hole.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
