[0024] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1-6 , the utility model discloses a robot fixture, including a flange 12 detachably connected to the robot, the end of the flange 12 away from the robot is fixedly connected to a driving assembly, one side of the driving assembly is fixedly connected to a limit assembly, sliders 2 are symmetrically arranged in the limit assembly, two sliders 2 are fixedly connected to the ends away from each other with clamps 3, two clamps 3 are detachably connected to tooling 4, and the clamps 3 are fixedly connected to the driving assembly.

[0027] The size of the flange 12 can be adjusted according to the flange on the robot to be installed. The flange 12 can be installed on the flange on the robot.

[0028] The utility model drives the two clamping jaws 3 to move through the driving assembly, so that the two clamping jaws 3 can quickly clamp or separate the tool fixture 4; at the same time, the slider 2 slides in the limit assembly, so that the clamping jaws 3 can move stably and can stably clamp or separate the tool fixture 4.

[0029] Further optimization scheme, the driving assembly includes a box body 1, the top surface of the box body 1 is fixedly connected to the bottom surface of the flange 12, one side of the box body 1 is fixedly connected to the limit assembly, the box body 1 is fixedly connected to the fixed top of the cylinder 11, and the piston end of the cylinder 11 extending out of the box body 1 is fixedly connected to the clamp 3.

[0030] To further optimize the solution, the cylinder 11 adopts a double-head double-outlet cylinder. The cylinder 11 uses a self-holding solenoid valve to ensure that the tooling 4 will not fall off after a sudden air failure; an air pressure sensor is installed in the air circuit of the solenoid valve to monitor the air circuit pressure in real time, so that the clamping jaws 3 can clamp accurately and smoothly.

[0031] By the telescopic movement of the two piston ends of the cylinder 11, the cylinder 11 can drive the two jaws 3 to approach or separate from each other. When the two jaws 3 approach each other, they can clamp the tooling 4. When the two jaws 3 separate from each other, they can unload the tooling 4.

[0032] In a further optimized solution, the limiting component includes an upper fixing plate 13. A lower fixing plate 14 is arranged below the upper fixing plate 13. Both the upper fixing plate 13 and the lower fixing plate 14 are fixedly connected to the side wall of the box body 1. The slider 2 is slidably connected between the upper fixing plate 13 and the lower fixing plate 14.

[0033] By the sliding of the slider 2 between the upper fixing plate 13 and the lower fixing plate 14, the jaw 3 can stably move between the upper fixing plate 13 and the lower fixing plate 14.

[0034] In a further optimized solution, a trapezoidal block 21 is fixedly connected to one side of the slider 2. The trapezoidal block 21 is slidably connected to the upper fixing plate 13 and the lower fixing plate 14.

[0035] In a further optimized solution, the upper fixing plate 13, the lower fixing plate 14 are adapted to the trapezoidal block 21.

[0036] On the opposite sides of the upper fixing plate 13 and the lower fixing plate 14, inclined surfaces adapted to the trapezoidal block 21 are provided. After the jaw 3 clamps the tooling 4, the jaw 3 will not deflect, enabling the jaw 3 to effectively clamp the tooling 4.

[0037] In a further optimized solution, on the opposite sides of the two jaws 3, guide and positioning pins 31 are symmetrically and fixedly connected respectively. An air supply pipe 32 is arranged between the two guide and positioning pins 31. The air supply pipe 32 is fixedly connected to the jaw 3. The guide and positioning pin 31 is detachably connected to the tooling 4. The air supply pipe 32 is detachably connected to and communicated with the tooling 4.

[0038] In a further optimized solution, the air supply pipe 32 penetrates through the jaw 3. One end of the air supply pipe 32 away from the tooling 4 is communicated with an air source.

[0039] In a further optimized solution, on both sides of the tooling 4, pin holes 41 are symmetrically opened respectively. An air hole 42 is arranged between the two pin holes 41. The air hole 42 is opened on the tooling 4.

[0040] The tooling 4 includes symmetrically arranged clamping blocks. The sizes of the middle holes on the two clamping blocks are adjusted according to the diameter of the held tool, enabling different tools to be installed without changing the size of the clamping blocks.

[0041] In a further optimized solution, the pin holes 41 and the guide and positioning pins 31 are arranged in one-to-one correspondence, and the air holes 42 and the air supply pipe 32 are arranged in correspondence.

[0042] Working process: When the gripper 3 moves towards the tooling 4, the guiding and positioning pin 31 is inserted into the pin hole 41. The two guiding and positioning pins 31 on each gripper 3 can effectively clamp and position the tooling 4, so that after the two grippers 3 clamp the tooling 4, the tooling 4 will not move, enabling the gripper 3 to stably clamp the tooling 4; it can not only maintain the locking force without falling off when the longitudinal force is abnormal, but also improve the reliability of the lateral force operation.

[0043] After the air supply pipe 32 is inserted into the air hole 42, the air source enters the air hole 42 through the air supply pipe 32, enabling the air source to supply air to the tool on the tooling 4, so that the tool does not require an external air source.

[0044] In order to reduce the overall weight, each component is made of aluminum, which can effectively reduce the overall mass and effectively avoid the overload problem of the small robot.

[0046] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
