[0031] During vehicle body reliability testing, in order to effectively test the insertion, removal, and rotation torque of the lock cylinder key, and to stably clamp the key to ensure testing efficiency and versatility, such as... Figure 1 As shown, this utility model provides a robot hand gripper for durability testing of lock cylinder keys. The robot hand gripper for durability testing of lock cylinder keys includes a docking assembly 1, a guide rod 2, a clamping assembly 3, and a locking assembly.
[0032] The docking assembly 1 includes a buffer 11 and a fixing member 12 arranged coaxially. The buffer 11 faces the robot hand, and a first fastener passes through the fixing member 12 and the buffer 11 to connect to the robot hand. The guide rod 2 is coaxially arranged with the fixing member 12, and one end of the guide rod 2 is connected to the fixing member 12. The clamping assembly 3 includes a mounting plate 31 and two grippers. The mounting plate 31 is fixedly mounted on the other end of the guide rod 2, and the two grippers are slidably mounted on the mounting plate 31 and are capable of clamping the lock cylinder key. A locking assembly is mounted on the two grippers and is used to lock the lock cylinder key to the grippers.
[0033] With the above setup, the locking component and gripper work together to stably lock the lock cylinder key, allowing for effective insertion, removal, and rotation torque testing by controlling the robot hand. Because the lock cylinder key is stably held, no adjustments are needed during testing, ensuring testing efficiency. Furthermore, since the gripper is slidably mounted on the mounting plate 31, the gripper spacing can be adjusted according to different types of lock cylinder keys, thus adapting to different types of lock cylinder key testing and improving versatility. The buffer 11 prevents rigid collisions that could break the lock cylinder key during insertion, ensuring smooth testing.
[0034] In some embodiments, the gripper is L-shaped and includes a horizontal plate 32 and a vertical plate 33 connected to each other. A first slot 321 is formed on the horizontal plate 32 along its extension direction, and a first threaded hole is formed on the mounting plate 31. A second fastener 4 passes through the first slot 321 and is screwed into the first threaded hole. This arrangement facilitates the installation of the gripper. Furthermore, by providing the first slot 321, the position of the gripper can be adjusted according to the type of lock cylinder key, thereby ensuring effective clamping of the lock cylinder key. In this embodiment, the second fastener 4 is a bolt. This method results in a simple structure and ease of adjustment.
[0035] In some embodiments, a second slot 331 is formed on the vertical plate 33 along its extending direction. The locking assembly includes at least two fixing bolts, which pass through the second slot 331 of the two grippers and the through hole on the lock cylinder key, and are connected to a nut. This configuration stably secures the lock cylinder key to the grippers, ensuring smooth subsequent testing. Furthermore, the second slot 331 allows for flexible adjustment of the position according to the length of the lock cylinder key, accommodating different types of lock cylinder keys. In other embodiments, a positioning pin can also be used as the locking assembly; further limitations are not specified here.
[0036] In some embodiments, a plurality of first mounting holes are spaced apart circumferentially along the buffer member 11, and a plurality of second mounting holes 121 opposite to the first mounting holes are spaced apart circumferentially along the fixing member 12. A plurality of first fasteners are provided corresponding to each of the plurality of first mounting holes. In this embodiment, the first fasteners are bolts. By using a plurality of first fasteners to install and fix the docking assembly 1 on the robot hand, a stable connection between the robot hand gripper used for the lock cylinder key durability test and the robot hand can be ensured.
[0037] In some embodiments, the fixing member 12 has a second threaded hole on the side opposite to the buffer member 11, and the guide rod 2 is screwed into the second threaded hole. The threaded connection facilitates the connection between the guide rod 2 and the fixing member 12. In other embodiments, the fixing member 12 and the guide rod 2 can also be welded together; this is not a limitation.
[0038] In some embodiments, the guide rod 2 is provided with a screwing groove 21, the bottom of which is a flat surface. By providing the screwing groove 21, it is convenient to screw and install the guide rod 2 using tools such as wrenches.
[0039] In some embodiments, the buffer 11 has a through hole on the side facing the robot's hand. By providing the through hole, the weight of the buffer 11 can be reduced, while also reducing the amount of material used.
[0040] In some embodiments, the first end of the guide rod 2, which is screwed into the second threaded hole, is located in the through hole, and a locking nut is screwed onto the first end of the guide rod 2. By providing the locking nut, the position of the guide rod 2 on the fixing member 12 can be further locked, preventing the guide rod 2 from moving axially.
[0041] In some embodiments, the buffer 11 is made of rubber. By using rubber, its elasticity can be utilized to provide cushioning during the insertion of the lock key.
[0042] In some embodiments, the mounting plate 31 has a third threaded hole, and the guide rod 2 is screwed into the third threaded hole. The third threaded hole facilitates the screwing installation of the guide rod 2 and the mounting plate 31.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
