DETAILED DESCRIPTION

[0016] The utility model will be further described below in combination with the drawings and examples, but not as the basis for limiting the utility model.

[0017] An embodiment of this utility model: A gripper testing device includes a base plate 1 with a groove in the middle. Four threaded through holes A11 are provided on the left side of the base plate 1. A bolt groove 13 is provided at the front and rear of the base plate 1 at the groove. A motor support base plate 4 is provided on the base plate 1 at the groove. A vertically arranged motor support platform 3 is fixed to the center of the top surface of the motor support base plate body 41 of the motor support base plate 4. A through hole B43 is provided at both the front and rear ends of the motor support base plate body 41. Locking bolts 44 pass through the through holes B43 and the bolt grooves 13 to fix the motor support base plate 4 and the base plate 1 together. A horizontally arranged motor 7 is fixed to the right side wall of the motor support platform 3. The motor shaft of the motor 7 passes through the motor shaft hole 32 on the motor support platform 3 and points towards the left end of the base plate 1. The diameter of the motor shaft hole 32 is slightly larger than that of the motor shaft of the motor 7. A support frame 6 is installed at the bottom of the base plate 1.

[0018] During the test, the gripper support plate 2 of the gripper device 8 is fixed to the base plate 1 with screws. The four threaded through holes A11 on the base plate 1 are designed to facilitate the fixing of the gripper support plate 2, thus enabling quick installation of the gripper device 8. After the gripper device 8 is installed, the motor support platform 3 is moved to the left side of the base plate 1, so that the motor shaft of the motor 7 is close to the rotating shaft of the gripper device 8 and the two are connected together. Then, the locking bolt 44 is tightened to fix the position of the motor support platform 3, and the motor 7 can be started for testing. After the test is completed, the locking bolt 44 is loosened and the motor support platform 3 is moved in the opposite direction, which enables quick separation of the motor shaft and the rotating shaft of the gripper device 8, facilitating the replacement of a new gripper device 8.

[0019] In the entire structure, since the locking bolt 44 passes through the bolt groove 13 and the size of the bolt groove 13 matches the size of the rod of the locking bolt 44, the locking bolt 44 can not only play the role of locking and fixing, but also act as a guide rod to ensure that the motor support platform 3 moves back and forth in a straight line during the movement.

[0020] Since the locking bolt 44 needs to extend to the bottom of the base plate 1, a support frame 6 is provided to prevent the bottom of the locking bolt 44 from directly contacting the surface of the test device mounting table. This creates a gap between the bottom of the base plate 1 and the mounting table, making it convenient to tighten and loosen the locking bolt 44.

[0021] On the left side of the base plate 1, a pressure plate 5 is provided on both the front and rear top surfaces. The pressure plate 5 extends towards the groove and has a screw through slot. The fastening screw 121 passes through the screw through slot and extends into the threaded through hole B12 on the base plate 1, thereby fixing the pressure plate 5. At the same time, the other end of the pressure plate 5 presses the motor support base plate 4 tightly, further fixing the motor support base plate 4 and preventing displacement of the motor support base plate 4 if the locking bolt 44 loosens. For motor support base plates 4 of different heights, shims can be used to raise the pressure plate 5.

[0022] A square groove 14 is provided in the middle of the base plate 1 at the groove. Two through holes A42 are provided in the middle of the base plate 4 of the motor support platform. Two threaded holes 34 are opened at the bottom of the motor support platform 3. The depth of the threaded holes 34 is 1 / 3 of the height of the motor support platform body 31. The fixing screw 33 passes through the through hole A42 and extends into the threaded hole 34, thereby fixing the motor support platform 3 and the base plate 4 of the motor support platform together. At the same time, the nut end of the fixing screw 33 is located in the square groove 14, thereby preventing the nut end of the fixing screw 33 from contacting the surface of the base plate 1 at the groove during the back and forth movement of the base plate 4 of the motor support platform.

[0023] Each of the four corners of the base plate 1 is provided with a bolt slot 15. The screw passes through the bolt slot 15 and extends into the threaded hole of the support frame 6, thereby realizing the quick installation of the support frame 6.

[0024] The end of the motor shaft has a spline structure, which can be quickly connected to the spline on the rotating shaft of the gripper device 8. Once the two spline structures are quickly engaged, the motor 7 can be started for testing, making the connection and separation between the motor shaft and the rotating shaft of the gripper device 8 faster and more convenient.
