[0033] The hardness testing device includes a material tray 1, a first transverse slide 4, a second transverse slide 5 and a robotic arm 2. The first transverse slide 4 is slidably provided with a workbench 41. The second transverse slide 5 is arranged above the first transverse slide 4, and a detection component 52 is slidably provided on the second transverse slide 5 in the vertical direction. The second transverse slide 5 is supported by a column 51. The robotic arm 2 is arranged between the material tray 1 and the first transverse slide 4, and loading and unloading are performed by the robotic arm 2. The use of the robotic arm 2 can reduce labor costs, reduce material waste and improve production efficiency, thereby bringing higher economic benefits. Among them, a first storage rack 7 and a second storage rack 8 are also provided within the range of motion of the robotic arm 2. The first storage rack 7 is adapted to the first gripper 21, and the first gripper 21 can be stored on the first storage rack 7. The second storage rack 8 is adapted to the second gripper 22, and the second gripper 22 can be stored on the second storage rack 8. Both the first gripper 21 and the second gripper 22 are adapted to the robotic arm 2. When the model and size of the workpiece to be inspected changes, the robot arm 2 needs to replace its gripper to adapt to the change of the workpiece. The robot arm 2 can store the clamped first gripper 21 or second gripper 22 on the first storage rack 7 or the second storage rack 8, and remove and install the second gripper 22 or the first gripper 21 from the second storage rack 8 or the first storage rack 7, which greatly improves the efficiency of the robot arm 2 in replacing the gripper, thereby improving the efficiency of hardness detection.

[0034] The specific structures of the first gripper 21, the first storage rack 7 and the detection assembly 52 are described below:

[0035] The first gripper 21 includes a first connecting base 211, a left claw 212, and a right claw 213. A linear slide 215 is provided on the first connecting base 211, and the left and right claws 212, 213 are mounted on the linear slide 215. The left and right claws 212, 213 are each connected to a telescopic assembly 214 in opposite directions. The telescopic assembly 214 and the linear slide 215 are arranged in the same direction. The telescopic assembly 214 can be a hydraulic cylinder. When the two telescopic assemblies 214 extend simultaneously, they can drive the left and right claws 212, 213 to close and clamp the workpiece. When the two telescopic assemblies 214 retract simultaneously, they can drive the left and right claws 212, 213 to open and release the workpiece.

[0036] The first storage rack 7 includes a first cover plate 73 and a bracket 71 adapted for the first gripper 21. The first cover plate 73 is arranged on the top of the bracket 71, and the first cover plate 73 is connected to a rotary cylinder. The rotation of the rotary cylinder can drive the first cover plate 73 to change between a horizontal state and a vertical state. After the first gripper 21 is placed on the first storage rack 7, the first cover plate 73 in the horizontal state can cover the upper part of the first gripper 21 to prevent debris and dust from falling on the first gripper 21. A first contact sensor 72 is also provided upward on the upper surface of the bracket 71. The first contact sensor 72 can be a commercially available EPSM12A high-precision contact sensor to automatically determine whether the first gripper 21 is placed on the first storage rack 7, thereby improving the degree of automation of the hardness detection device.

[0037] Inspection assembly 52 includes a vertically mounted milling spindle, a height sensor, a force-applying mechanism, and a visual camera. A tool on the milling spindle mills the upper surface of the workpiece to be inspected, smoothing the surface. The height sensor determines the amount of milling during this process. The force-applying mechanism applies pressure to the surface to be inspected, while the visual camera records the indentation and the height sensor measures the depth. The hardness of the workpiece is determined by combining the shape and depth of the indentation.

[0038] The specific structures of the second gripper 22, the second storage rack 8 and the tooling beam 6 are described below:

[0039] The second gripper 22 includes a second connecting base 221 and a centering chuck 222 disposed on the second connecting base 221. The centering chuck 222 can be a three-jaw self-centering chuck 222. The second storage rack 8 includes a base 81, an annular support plate 82, and a support rod 84. The annular support plate 82 is disposed on the base 81, and the support rod 84 is disposed between the two annular support plates 82. The upper portion of the support rod 84 is connected to two second cover plates 85 via two rotating cylinders. When the rotating cylinder drives the second cover plate 85 to rotate to a horizontal position, the second cover plate 85 is disposed horizontally directly above the annular support plate 82.

[0040] After the second gripper 22 is placed on the second storage rack 8, the horizontally positioned second cover plate 85 shields the upper portion of the second gripper 22, preventing debris and dust from settling on the second gripper 22. A second contact sensor 83, which can be a commercially available EPSM12A high-precision contact sensor, is also positioned upward on the upper surface of the annular support plate 82 to automatically determine whether the second gripper 22 is placed on the second storage rack 8, thereby enhancing the automation level of the hardness testing device.

[0041] The apparatus further includes a transverse tooling beam 6, positioned above the first transverse slide rail 4 and connected to a vertically mounted lifting support mechanism 61. Vertically, the tooling beam 6 is offset from the second transverse slide rail 5. The lifting support mechanism 61 drives the tooling beam 6 downward to press against the workpiece on the workbench 41. Prior to inspecting a workpiece on the workbench 41, the tooling beam 6 is first pressed downward to ensure close contact with the workbench 41, preventing any gaps between the workpiece and the workbench 41 that could affect subsequent inspection.

[0042] The specific structures of the primary material transport slide 3, the secondary material transport slide 31 and the material tray 1 are described below:

[0043] It also includes a horizontally arranged primary material transport slide 3 and a secondary material transport slide 31, the secondary material transport slide 31 is slidably arranged on the primary material transport slide 3, the primary material transport slide 3 and the secondary material transport slide 31 are arranged vertically, and the robot arm 2 is arranged on the secondary material transport slide 31. The sliding between the primary material transport slide 3 and the secondary material transport slide 31 can drive the robot arm 2 to move horizontally.

[0044] At least two material trays 1 are provided, arranged side by side along the length of the primary material transport rail 3. One tray 1 is used for loading, and the other for unloading, without interfering with each other. A first storage rack 7 and a second storage rack 8 are located at one end of the primary material transport rail 3. The first and second storage racks 7, 8 are arranged around the primary material transport rail 3, making it easy for the robot arm 2 to place and remove the first and second storage racks 7, 8, respectively.

[0045] The specific workflow of this utility model is as follows:

[0046] First, according to the shape of the workpiece to be inspected, the first gripper 21 or the second gripper 22 is installed on the robot arm 2. Then the workpiece is placed on the material tray 1, and the robot arm 2 moves horizontally along the primary material transport slide 3 and the secondary material transport slide 31 to clamp the workpiece onto the workbench 41. The workbench 41 moves along the first transverse slide 4 to the lower part of the tooling beam 6, and the lifting support mechanism 61 drives the tooling beam 6 downward to press the workpiece. The workbench 41 moves along the first transverse slide 4 to the bottom of the detection component 52 for inspection. Finally, the workbench 41 is reset, and the robot arm 2 clamps the inspected workpiece on the workbench 41 onto the material tray 1 to complete the inspection of the workpiece. When the model of the workpiece to be inspected changes and the gripper needs to be replaced, the robot arm 2 moves horizontally along the primary material transport slide 3 and the secondary material transport slide 31 to a position close to the first storage rack 7 and the second storage rack 8 to quickly replace the first gripper 21 or the second gripper 22.

[0047] It can be seen that in the above-mentioned hardness detection device, when the model and size of the workpiece to be detected changes, the robot arm 2 needs to replace the gripper to adapt to the change of the workpiece. The robot arm 2 can store the clamped first gripper 21 or the second gripper 22 on the first storage rack 7 or the second storage rack 8, and remove and install the second gripper 22 or the first gripper 21 from the second storage rack 8 or the first storage rack 7, which greatly improves the efficiency of the robot arm 2 in replacing the gripper, thereby improving the hardness detection efficiency.

[0048] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
