[0025] Referring to Figure 1 and Figure 2 The utility model provides a kind of mechanical gripper for metal plate processing, comprising: support 1, turnover plate 2, clamping plate 3 and drive assembly 4.

[0026] In the embodiment, support 1 is sheet-shaped. Specifically, support 1 has a front surface and a back surface. The back surface of support 1 is provided with a mechanical arm to move the entire mechanical gripper.

[0027] The opposite sides of the front surface of support 1 are formed with support plates 11. The front surface of support 1 is provided with a base 12. The base is arranged at the middle position of the front surface of the support.

[0028] The number of turnover plates 2 is two. The two turnover plates are arranged between the two support plates 11. The middle part of the turnover plate 2 is hinged to the support plate 11. One end of the turnover plate 2 extends to the outside of the side away from the support 1 of the two support plates 11.

[0029] As a preferred embodiment, the middle part of the turnover plate 2 is hinged to the support plate 11 through a first hinge shaft 21.

[0030] The number of clamping plates 3 is two. The clamping plates 3 are arranged on the opposite sides of the two turnover plates 2. The clamping plates 3 are angularly connected to one end of the turnover plates 2. In the embodiment, the clamping plates are arranged towards the opposite clamping plates. The first clamping space for the metal plate 5 to pass through is formed between the two clamping plates 3.

[0031] The inner side of the clamping plate 3 is reversibly provided with a conveying roller 31. The second clamping space for the metal plate 5 to pass through is formed between the two conveying rollers 31. The second clamping space is aligned with the first clamping space.

[0032] As a preferred embodiment, the roller shaft of the conveying roller 31 is connected with a support rod 32. The support rod 32 is reversibly installed on the inner side of the clamping plate 3 through a second hinge shaft 33. The second hinge shaft 33 is arranged in the same direction as the first hinge shaft 21. The electric hydraulic push rod 34 is hinged between the support rod 32 and the clamping plate 3.

[0033] In the embodiment, a first motor is mounted on the support rod 32. The first motor is drivingly connected to the roller shaft of the conveying roller 31.

[0034] A driving assembly 4 is mounted on the base 12. The driving assembly 4 is used to push the other end of the two turnover plates 2.

[0035] As a preferred embodiment, the driving assembly 4 comprises a driving sleeve 41, a lead screw 42 and a second motor.

[0036] Specifically, the driving sleeve 41 is arranged along the thickness direction of the support plate. The driving sleeve 41 is formed with an internal thread. The driving sleeve 41 is rotatably mounted on the base 12.

[0037] The number of the lead screws 42 is two. The front surface of the bracket 1 is mounted with a support sleeve (not shown in the figure). The lead screws 42 are movably arranged in the support sleeve. The lead screws can move along the axial direction of the support sleeve and can rotate in the support sleeve. The outer diameter of the lead screws is adapted to the inner diameter of the support sleeve.

[0038] One end of the lead screw 42 is screwed to the driving sleeve 41. The other end of the lead screw 42 is hingedly connected with a sliding block.

[0041] In combination with Figure 1 and Figure 2 shown, when the mechanical gripper for metal plate machining of the utility model is used to grab the metal plate, the metal plate is arranged between the two clamping plates. After the metal plate is arranged between the two clamping plates, the second motor drives the driving sleeve to rotate through the driving gear, so that the lead screws at both ends of the driving sleeve move away from each other at the same time. At this time, the turnover plate rotates, so that the two clamping plates approach each other and clamp the metal plate (i.e. the metal plate is arranged in the first clamping space). Then, the electric hydraulic push rod is elongated, the support rod is turned over, so that the two driving rollers are pressed against the opposite sides of the metal plate, i.e. the metal plate is arranged in the second clamping space.

[0042] The mechanical gripper for metal plate machining of the utility model is driven by the mechanical arm to load the metal plate into the sheet metal machining machine. At this time, the second motor is reversely rotated, so that the two clamping plates move away from each other by a distance. At this time, the metal plate is movably arranged between the two clamping plates. At the same time, the first motor drives the conveying roller shaft to rotate, and the two conveying roller shafts push the metal plate into the sheet metal machining machine for sheet metal machining.

[0043] The mechanical gripper for metal plate processing is used for clamping the metal plate through the two clamping plates, and the metal plate is clamped and transferred to the sheet metal processing machine through the two conveying roller shafts, so that the sheet metal processing of the metal plate improves the feeding processing efficiency and conveying stability.
