Description

Technical Field

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

[0002] With the rapid development of industrial automation and intelligent manufacturing, industrial robots have become an indispensable and important piece of equipment in modern manufacturing. They are widely used in many fields such as automobile manufacturing, electronic assembly, and machining, performing a variety of tasks such as welding, handling, painting, and assembly.

[0003] In these high-precision, high-load operations, the importance of the locking mechanism is self-evident. It not only needs to ensure the secure fixation of the robot's end effector (such as a clamp or welding torch) to prevent loosening or falling off during operation, but also needs to adapt to various complex working conditions and dynamic environments to ensure the continuity and safety of the operation.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] When using existing locking mechanisms, a lot of adjustments and modifications are often required when dealing with end effectors of different sizes, shapes and positions. This inflexibility not only reduces production efficiency, but also increases operating costs and maintenance difficulty. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a locking mechanism for industrial robots to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides a locking mechanism for an industrial robot, comprising a robot forearm, a rotating shaft, and a connector. The rotating shaft is disposed at the front end of the robot forearm, and the connector is disposed at one end of the rotating shaft. The mechanism also includes an L-shaped support, a cylinder, a sliding support plate, a connecting block, and a locking mechanism. The L-shaped support is disposed on the outside of the robot forearm and is fixedly connected to the rotating shaft. The L-shaped support is fixedly connected to the upper end of the cylinder. The sliding support plate is slidably connected inside the L-shaped support. The connecting block is fixedly connected to the outer end of the sliding support plate and is fixedly connected to the movable end of the cylinder. The locking mechanism is disposed at the lower end of the sliding support plate.

[0008] Optionally, the locking mechanism includes a supporting main frame box, a sliding tube, a connecting slider, and a rack. The supporting main frame box is fixedly connected to the sliding support plate. The sliding tube is slidably connected to one end of the inner side of the supporting main frame box. The connecting slider is fixedly connected to one end of the outer side of the sliding tube. The rack is fixedly connected to one end above the connecting slider. A rotating shaft, a motor, and a gear are also included. The rotating shaft is rotatably connected to the upper part of the supporting main frame box and extends out of the supporting main frame box at both ends. The motor is fixedly connected to the outer side of the supporting main frame box, and the gear is fixedly connected to one end of the outer side of the rotating shaft. A threaded rod, a top plate, a rubber top block, and a rotating component are also included. The threaded rod is threadedly connected to the inside of the sliding tube. The top plate is fixedly connected to one end of the threaded rod head. The rubber top block is fixedly connected to the surface of the top plate, and the rotating component is fixedly connected to one end of the threaded rod tail.

[0009] Optionally, the L-shaped support, cylinder, sliding support plate, connecting block and locking mechanism are each provided in two sets, with the two sets of L-shaped support arranged on both sides of the robot forearm.

[0010] Optionally, the connecting slider is slidably connected to the supporting main frame box, the motor output end is fixedly connected to the rotating shaft, and the gear is meshed with the rack.

[0011] Optionally, the sliding tube, threaded rod, top plate, rubber top block and rotating part are each provided in three sets, and the connecting slider, rack, motor and gear are each provided in two sets. The two sets of connecting sliders are evenly fixedly connected between the three sets of sliding tubes, the two sets of motors are symmetrically arranged on both sides of the main support box, and the two sets of gears are symmetrically arranged at both ends of the outer side of the rotating shaft.

[0012] The beneficial effects of this utility model are as follows: The motor drives the rotation of the shaft and gears. Through the connection between the gears and rack, and the connection between the sliding tube and connecting slider and the support frame box, the sliding tube and connecting slider move within the support frame box, thereby changing the position of the threaded rod inside the sliding tube. This causes the top plate and rubber block at one end of the threaded rod to extend. The arrangement of these two locking mechanisms allows the end effector to be clamped from both sides, achieving the purpose of locking. The rubber block increases the stability and cushioning of the clamping. By twisting the rotating component to drive the rotation of the threaded rod, the length of the threaded rod can be adjusted. Adjusting multiple sets of threaded rods allows for better clamping and locking of end effectors with different regular surfaces. Through the connection between the cylinder and the connecting block, the driving cylinder can drive the sliding support plate to extend from the L-shaped support component, thereby adjusting the length of the sliding support plate to better accommodate end effectors of different sizes.

The L-shaped support 4 is fixedly connected to the upper end of the cylinder 5. The sliding support plate 6 is slidably connected to the inside of the L-shaped support 4. The connecting block 7 is fixedly connected to the outer end of the sliding support plate 6 and is fixedly connected to the movable end of the cylinder 5. The locking mechanism 8 is disposed at the lower end of the sliding support plate 6.

[0022] In some optional specific embodiments, such as Figures 1 to 6 As shown, the locking mechanism 8 includes a supporting main frame box 801, a sliding tube 802, a connecting slider 803, and a rack 804. The supporting main frame box 801 is fixedly connected to the sliding support plate 6. The sliding tube 802 is slidably connected to one end of the inner side of the supporting main frame box 801. The connecting slider 803 is fixedly connected to one end of the outer side of the sliding tube 802. The rack 804 is fixedly connected to one end above the connecting slider 803. The mechanism also includes a rotating shaft 805, a motor 806, and a gear 807. The rotating shaft 805 is rotatably connected inside the supporting main frame box 801. Above, with support frame boxes 801 extending from both ends, the motor 806 is fixedly connected to the outside of the support frame box 801, and the gear 807 is fixedly connected to one end of the outer side of the rotating shaft 805; threaded rod 808, top plate 809, rubber top block 810 and rotating component 811, the threaded rod 808 is threadedly connected to the inside of the sliding tube 802, the top plate 809 is fixedly connected to one end of the head of the threaded rod 808, the rubber top block 810 is fixedly connected to the surface of the top plate 809, and the rotating component 811 is fixedly connected to one end of the tail of the threaded rod 808.

[0023] In some optional specific embodiments, such as Figures 1 to 6 As shown, there are two sets of the L-shaped support 4, cylinder 5, sliding support plate 6, connecting block 7 and locking mechanism 8, and the two sets of L-shaped support 4 are arranged on both sides of the robot forearm 1.

[0024] In some optional specific embodiments, such as Figures 1 to 6 As shown, the connecting slider 803 is slidably connected to the supporting main frame box 801, the output end of the motor 806 is fixedly connected to the rotating shaft 805, and the gear 807 is meshed with the rack 804.

[0025] In some optional specific embodiments, such as Figures 1 to 6 As shown, the sliding tube 802, threaded rod 808, top plate 809, rubber top block 810 and rotating component 811 are each provided in three sets, and the connecting slider 803, rack 804, motor 806 and gear 807 are each provided in two sets.

The L-shaped support 4 rotates with the rotation of the rotating shaft 2, thereby ensuring that the locking mechanism 8 always corresponds to the robot's end effector. The rotating shaft 805 and gear 807 are driven to rotate by the motor 806. Through the connection between the gear 807 and rack 804, and the connection between the sliding tube 802 and connecting slider 803 and the support frame box 801, the sliding tube 802 and connecting slider 803 move within the support frame box 801, thereby changing the position of the threaded rod 808 inside the sliding tube 802. This causes the top plate 809 and rubber top block at one end of the threaded rod 808 to move. Extending 810, the two sets of locking mechanisms 8 can clamp the end effector from both sides, achieving the purpose of locking. The rubber top block 810 increases the stability and cushioning of the clamping. By twisting the rotating component 811 to drive the rotation of the threaded rod 808, the length of the threaded rod 808 can be adjusted. By adjusting multiple sets of threaded rods 808, end effectors with different regular surfaces can be better clamped and locked. Through the connection between the cylinder 5 and the connecting block 7, the driving cylinder 5 can drive the sliding support plate 6 to extend from the L-shaped support component 4, thereby adjusting the length of the sliding support plate 6 to better accommodate end effectors of different sizes.
