DETAILED DESCRIPTION OF THE INVENTION

[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0023] AttachedFigures 1-4 The multi-functional handling fixture described in the present invention includes a mounting base 1, a bar clamping assembly 3 provided at the bottom of the mounting base 1, and a sheet clamping assembly 2 provided at one end of the mounting base 1. The bar clamping assembly 3 includes a fixed clamping plate 31 provided at one end of the bottom of the mounting base 1, a linear servo module 33 provided at the bottom of the mounting base 1 and placed along the length direction of the mounting base 1, and a movable clamping plate 34 provided on the driving end of the linear servo module 33. The sheet clamping assembly 2 includes a mounting plate 21 provided on the back of the fixed clamping plate 31, two guide rails 23 provided on the front of the mounting plate 21 and placed along the length direction of the mounting plate 21, clamping jaws 26 respectively provided on the two guide rails 23, and two clamping cylinders 22 provided on the back of the mounting plate 21 to drive the two clamping jaws 26 to approach or move away simultaneously. When working: The multi-functional handling fixture described in the present invention is installed on the manipulator 5. When it is necessary to grasp a bar, under the drive of the manipulator 5, the fixed clamping plate 31 is first made to abut against one end of the bar, and then the movable clamping plate 34 is driven by the linear servo module 33 to abut against the other end of the bar, so that the bar can be firmly clamped for handling, effectively avoiding the bar from tilting during handling and causing danger. When it is necessary to grasp a sheet, under the drive of the manipulator 5, the sheet is made to be located between the two clamping jaws 26, and then the two clamping cylinders 22 respectively drive the two clamping jaws 26 to approach simultaneously to clamp the sheet, facilitating grasping the sheet from the cutting equipment or grasping the sheet onto the cutting equipment. When the bar clamping assembly 3 cannot directly grasp the bar, first clamp one end of the bar by the sheet clamping assembly 2 and pull it out, and then grasp it, with rich functions.

[0024] Furthermore, the sheet clamping assembly 2 further includes a synchronization assembly. The synchronization assembly includes a synchronization rod 24 rotatably provided at the center of the mounting plate 21, and two connecting rods 25 whose two ends are respectively hinged to one end of the synchronization rod 24 and the clamping jaw 26. When the two clamping cylinders 22 respectively drive the two clamping jaws 26 to approach or move away simultaneously, under the action of the synchronization rod 24 and the two connecting rods 25, the two clamping jaws 26 can be guaranteed to move synchronously.

[0025] Furthermore, the mounting plate 21 is hinged to the back of the fixed clamping plate 31. A flipping cylinder 4 for driving the mounting plate 21 to flip is provided on the mounting base 1. When working: Driven by the flipping cylinder 4, the mounting plate 21 can be placed horizontally or vertically, making it more flexible to use when clamping the bar or the sheet.

[0026] Furthermore, the clamping surfaces of the two clamping jaws 26 are both provided with arc-shaped first rubber pads 27, which can not only increase the friction force to facilitate clamping the material, but also prevent scratching the surface of the material.

[0027] Furthermore, the clamping surfaces of the fixed clamping plate 31 and the movable clamping plate 34 are both provided with second rubber pads 35, which can not only increase the friction force to facilitate clamping the material, but also prevent scratching the surface of the material.

[0028] Furthermore, pressure sensors are provided inside both the first rubber pad 27 and the second rubber pad 35, which can detect the clamping torque in real time and enable more stable grasping of materials.

[0029] Furthermore, limit switches 32 for restricting the movement range of the movable clamping plate 34 are respectively provided at both ends of one side of the mounting base 1, which play a role of limit protection.

[0030] Furthermore, reinforcing brackets 36 are provided on the backs of both the fixed clamping plate 31 and the movable clamping plate 34, which play a reinforcing role, prevent the fixed clamping plate 31 and the movable clamping plate 34 from deforming during material grasping, and improve the service life.

[0031] Furthermore, a plurality of hollow structures 11 are provided on the mounting base 1, which can reduce the weight, thereby reducing the requirements for the manipulator 5 and saving costs.

[0032] Furthermore, a reinforcing rod 6 for connecting the manipulator 5 is also provided on the mounting base 1; after the multifunctional handling jig of the present invention is installed on the manipulator 5, the reinforcing rod 6 plays a reinforcing role, making the connection more stable and not prone to shaking during the handling process.

[0033] The above are only specific application examples of the present invention and do not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present invention.
