Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to a gripping mechanism for an industrial robot. Background Technology

[0002] Industrial robots are processing robots used in the industrial field that can imitate human actions to assemble products, transport logistics, etc. Industrial robots can use mechanical transmission to complete corresponding processing operations. Industrial robots are generally equipped with corresponding gripping mechanisms to grasp items and then perform subsequent processing operations.

[0003] However, the gripping mechanism of existing industrial robots usually grips one side of the object during operation. When unloading the object, this gripping method can only place the object from top to bottom. However, some processing machines have cage doors, frames or other structures on the top, which makes it inconvenient to place the object from top to bottom. Therefore, it is necessary to place the object through one side of the processing machine.

[0004] Therefore, it is necessary to provide a gripping mechanism for industrial robots to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gripping mechanism for industrial robots.

[0007] A gripping mechanism for an industrial robot includes a gripping module and a mounting plate;

[0008] The grasping module includes a slide groove with a cross-shaped cross-section. A cross-shaped slider is provided inside the slide groove. The outer sides of the cross-shaped slider are respectively connected to a pair of connecting rods by pins. The inner two ends of the slide groove are respectively movably connected to one end of a lead screw. The lead screw is threaded to the cross-shaped slider. One end of the lead screw passes through the slide groove. The output shaft of the motor is fixedly connected to one end of the lead screw. The output shaft of the motor passes through a U-shaped plate. The motor is fixedly connected to the U-shaped plate.

A set of corresponding U-shaped protrusions are fixedly connected to the outer side of the square rod. A set of U-shaped protrusions on the same side are hinged to a set of corresponding connecting rods. A set of connecting rods on the same side are arranged parallel to each other. One end of a set of connecting rods on the same side is fixedly connected to a corresponding clamping rod. The side of a set of connecting rods near the slide groove is hinged to one end of a corresponding connecting rod through a pin.

[0010] Preferably, the mounting plate is fixedly connected to one side of the U-shaped plate.

[0011] Preferably, the mounting plate is provided with a set of evenly arranged mounting holes.

[0014] Compared with related technologies, the beneficial effects of this utility model are:

[0015] 1. Use bolts to install the mounting plate onto the robotic arm of the industrial robot through the mounting holes to fix the device. Through the gripping module, it can clamp and fix the inner and outer walls of the cylindrical object, and grasp one end of the cylindrical object, making it easy for the robotic arm to put the cylindrical object into the processing equipment from one side.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] A gripping mechanism for an industrial robot includes a gripping module 2 and a mounting plate 3;

[0029] The gripping module 2 includes a slide groove 22 with a cross-shaped cross-section. A cross-shaped slider 211 is provided inside the slide groove 22. The outer sides of the cross-shaped slider 211 are respectively connected to a pair of connecting rods 28 by pins. The two ends of the inner side of the slide groove 22 are respectively movably connected to one end of a lead screw 29. The lead screw 29 is threaded to the cross-shaped slider 211. One end of the lead screw 29 passes through the slide groove 22. The output shaft of the motor 210 is fixedly connected to one end of the lead screw 29. The output shaft of the motor 210 passes through a U-shaped plate 21. The motor 210 is fixedly connected to the U-shaped plate 21.

[0030] The U-shaped plate 21 is fixedly connected to the slide groove 22. A square rod 23 is fixedly connected to one side of the slide groove 22. A set of corresponding U-shaped protrusions 24 are fixedly connected to the outer side of the square rod 23. A set of U-shaped protrusions 24 on the same side are hinged to a set of corresponding connecting rods 27. A set of connecting rods 27 on the same side are arranged parallel to each other. One end of a set of connecting rods 27 on the same side is fixedly connected to a corresponding clamping rod 26. The side of a set of connecting rods 27 near the slide groove 22 is hinged to one end of a corresponding connecting rod 28 through a pin.

[0031] The mounting plate 3 is fixedly connected to one side of the U-shaped plate 21.

[0032] The mounting plate 3 is provided with a set of evenly arranged mounting holes 31.

[0033] A set of evenly arranged anti-slip blocks 25 are fixedly provided on one side of each of the clamping rods 26.

[0034] On the other side of one set of clamping rods 26, a set of evenly arranged anti-slip blocks 212 are fixedly provided.

[0035] Working principle: First, the mounting plate 3 is installed on the robotic arm of the industrial robot using bolts through the mounting holes 31, thus fixing the device. When it is necessary to grip the outer wall of the cylindrical object 1, a set of clamping rods 26 is placed on the outer end of the cylindrical object 1. The motor 210 is started, and the motor 210 drives the lead screw 29 to rotate. The lead screw 29 drives the cross-shaped slider 211 to slide along the slide groove 22. The cross-shaped slider 211 drives a set of connecting rods 1 28 to swing. The corresponding set of connecting rods 1 28 drives a corresponding set of connecting rods 27 to swing. The corresponding set of connecting rods 27 drives the clamping rods 26 to move, so that the set of clamping rods 26 moves closer to the outer wall of the cylindrical object 1, thereby clamping and fixing the cylindrical object 1. At the same time, a set of anti-slip blocks 25 can increase the friction between the cylindrical object 1 and the clamping rods 26, making the clamping of the cylindrical object 1 more stable.

[0036] When gripping the inner wall of the cylindrical object 1 as needed, a set of clamping rods 26 are placed at the end of the inner wall of the cylindrical object 1. The above operation is repeated to clamp and fix the inner wall of the cylindrical object 1 with a set of clamping rods 26. At the same time, a set of anti-slip blocks 212 can increase the friction between the cylindrical object 1 and the clamping rods 26, making the clamping of the cylindrical object 1 more stable and facilitating the subsequent operation of the cylindrical object 1 by the robotic arm of the industrial robot.

[0037] Beneficial effects: The mounting plate 3 is installed on the robotic arm of the industrial robot using bolts through the mounting holes 31, thus fixing the device. Through the gripping module 1, the inner and outer walls of the cylindrical object 1 can be clamped and fixed, and one end of the cylindrical object 1 can be gripped, making it easier for the robotic arm to put the cylindrical object 1 into the processing equipment from one side. At the same time, the setting of a set of anti-slip blocks 1 25 and a set of anti-slip blocks 212 can increase the friction between the cylindrical object 1 and the gripping rod 26, making the gripping of the cylindrical object 1 more stable and facilitating subsequent operations of the cylindrical object 1 by the robotic arm of the industrial robot.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
