Description

Technical Field

[0001] This utility model relates to the field of robot gripper technology, and in particular to robot grippers. Background Technology

[0002] Robots are an important piece of equipment in modern industrial production and processing. They are favored by manufacturers because of their intelligence and high efficiency. When facing different production lines, robots need to be equipped with different types and models of grippers according to different products. The grippers are installed at the robot's operating end to ensure that intelligent production and processing operations can be carried out stably.

[0003] Existing grippers are inadequate in automatically adapting to products of different sizes and maintaining a constant gripping force, and their overall practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a robotic gripper that can automatically adapt to gripping materials of different sizes and achieve a fixed gripping force, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A robotic gripper includes a first mounting base, a second mounting base fixedly mounted inside the first mounting base, a motor fixedly mounted on the outer surface of the second mounting base, a screw fixedly connected to one end of the motor's rotating shaft, a linkage block threaded onto the external thread of the screw, a linkage seat on one side of the linkage block, two mounting holes on the outer surface of the linkage seat adjacent to the linkage block, and a second detection seat mounted inside the mounting holes, a piston rod slidably mounted inside the second detection seat, one end of the piston rod fixedly connected to the side surface of the linkage block, a first detection seat fixedly mounted on the outer surface of the first mounting base, the two second detection seats and the first detection seat connected by a fluid guiding hose, both the second and first detection seats being filled with hydraulic oil, and a pressure sensor fixedly mounted inside the mounting hole on the side surface of the first detection seat.

[0007] By adopting the above technical solution, the piston rod, the first detection seat, the second detection seat, and the hydraulic oil can be used to convert and transmit the force, and the pressure sensor can be used to detect the pressure to realize the feedback detection of the clamping force. This allows the gripper to automatically adapt to the gripping operation of materials of different sizes and achieve fixed-value gripping.

[0008] Furthermore, two limiting slide rods are fixedly connected to the outer surface of the second mounting base, and the limiting slide rods pass through the sliding holes on the outer surface of the linkage block.

[0009] By adopting the above technical solution, it is ensured that the linkage block will not rotate when it moves.

[0010] Furthermore, a clamping arm is rotatably mounted at each end of the outer surface on both symmetrical sides of the second mounting base.

[0011] By adopting the above technical solution, the rotation of the gripping arm can be used to perform material gripping operations.

[0012] Furthermore, a linkage rod is rotatably connected to each end of the outer surface on both sides of the linkage seat, and the other end of the linkage rod is rotatably connected to the middle section of the clamping arm.

[0013] By adopting the above technical solution, it is ensured that the linkage rod can drive the clamping arm to rotate, thereby enabling effective material gripping operations.

[0014] Furthermore, one end of the clamping arm is provided with a threaded hole, and a clamping end is installed in the internal thread of the threaded hole.

[0015] By adopting the above technical solution, the clamping end can be flexibly loaded and unloaded.

[0016] Furthermore, a through hole is provided on the outer surface of the linkage seat, and both the screw and the limiting slide rod pass through the through hole on the outer surface of the linkage seat.

[0017] By adopting the above technical solution, the screw and limit slide rod are prevented from causing obstacles to the movement of the linkage seat.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for material gripping by starting a motor, which drives the screw to rotate. Since the screw is threadedly connected to a linkage block, and the linkage block is slidably fitted onto the outside of a limiting slide rod, the rotation of the screw effectively moves the linkage block along the screw's axial direction. This movement of the linkage block then moves the piston rod. The piston rod's movement inside the second detection seat causes hydraulic oil inside the second detection seat to flow through the guide hose into the first detection seat. This change in oil pressure inside the first detection seat is accurately detected by a pressure sensor, which transmits the detection data to the control system. This allows for automatic gripping of different materials at a fixed pressure, making it highly practical and widely applicable.

[0020] 2. This utility model provides a threaded hole at one end of the clamping arm, with the clamping end threaded into the threaded hole at the end of the clamping arm. This allows for flexible replacement of different types and models of clamping ends as needed during use, resulting in high flexibility in loading and unloading and improving overall practicality.

[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The robotic gripper includes a first mounting base 1, a second mounting base 5 fixedly mounted inside the first mounting base 1, a motor 13 fixedly mounted on the outer surface of the second mounting base 5, a screw 11 fixedly connected to one end of the rotating shaft of the motor 13, a linkage block 12 threaded onto the external thread of the screw 11, a linkage seat 9 provided on one side of the linkage block 12, two mounting holes provided on the outer surface of the linkage seat 9 adjacent to the linkage block 12, and a second detection seat 14 installed inside the mounting holes, a piston rod 15 slidably mounted inside the second detection seat 14, one end of the piston rod 15 fixedly connected to the side surface of the linkage block 12, a first detection seat 2 fixedly mounted on the outer surface of the first mounting base 1, the two second detection seats 14 and the first detection seat 2 connected by a fluid guiding hose 3, both the second detection seats 14 and the first detection seat 2 filled with hydraulic oil, a mounting hole provided on the side surface of the first detection seat 2, and a pressure sensor 4 (PN7094) fixedly mounted inside the mounting hole, and a second detection seat 14 fixedly mounted on the outer surface of the second mounting base 5. Two limiting slide rods 10 are connected, and the limiting slide rods 10 pass through the sliding holes on the outer surface of the linkage block 12. The outer surface of the linkage seat 9 is provided with through holes. Both the screw 11 and the limiting slide rods 10 pass through the through holes on the outer surface of the linkage seat 9. When gripping materials, the motor 13 can be started, and the motor 13 drives the screw 11 to rotate. Since the screw 11 is threadedly connected to the linkage block 12, and the linkage block 12 is slidably sleeved on the outside of the limiting slide rods 10, the rotation of the screw 11 can effectively drive the linkage block 12 to move along the axial direction of the screw 11. At this time, the linkage block 12 drives the piston rod 15 to move. The movement of the piston rod 15 inside the second detection seat 14 can drive the hydraulic oil inside the second detection seat 14 to enter the interior of the first detection seat 2 through the liquid guide hose 3. At this time, the oil pressure inside the first detection seat 2 changes, which can be accurately detected by the pressure sensor 4. The pressure sensor 4 can transmit the detection data to the control system, which can automatically realize the fixed pressure gripping operation of different materials. It is highly practical and has a wide range of applications.

[0028] Reference Figure 2 A clamping arm 6 is rotatably mounted at both ends of the symmetrical outer surfaces of the second mounting base 5. A linkage rod 8 is rotatably connected at both ends of the symmetrical outer surfaces of the linkage base 9. The other end of the linkage rod 8 is rotatably connected to the middle section of the clamping arm 6. One end of the clamping arm 6 is provided with a threaded hole, and a clamping end 7 is installed in the threaded hole. By providing a threaded hole at one end of the clamping arm 6, the clamping end 7 is threadedly connected to the threaded hole at the end of the clamping arm 6. During use, different types and models of clamping end 7 can be flexibly replaced according to actual needs, which is highly flexible in loading and unloading and also improves the overall practicality.

[0029] Working principle: First, install the gripper on the robot's operating end. Then, select the appropriate gripping end head 7 according to actual needs. Next, thread the gripping end head 7 onto one end of the gripping arm 6. Normal operation is then possible. During use, start the motor 13. The motor 13 drives the screw 11 to rotate. Since the screw 11 is threadedly connected to the linkage block 12, and the linkage block 12 is slidably sleeved on the outside of the limit slide rod 10, the rotation of the screw 11 effectively drives the linkage block 12 to move along the axial direction of the screw 11. At this time, the linkage block 12 drives the piston rod 15 to move. The piston rod 15 is then positioned on the second detection seat 14. The internal movement can drive the second detection seat 14 and the linkage seat 9 to move along the axial direction of the screw 11. Under the linkage of the linkage rod 8, the clamping arm 6 rotates. At this time, the two clamping arms 6 placed opposite each other can effectively clamp the material and realize the material gripping operation. During the gripping process, the piston rod 15 can drive the hydraulic oil inside the second detection seat 14 to enter the interior of the first detection seat 2 through the liquid guide hose 3. At this time, the oil pressure inside the first detection seat 2 changes and can be accurately detected by the pressure sensor 4. The pressure sensor 4 can transmit the detection data to the control system and can automatically realize the fixed pressure gripping operation of different materials.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
