Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in 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. The nouns and pronouns about people in this patent application are not limited to specific genders.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form as well.

[0048] First, please refer to Figure 1, shows a floating clamp mechanism for turning over and carrying a machine base according to an embodiment of the utility model. The machine base is particularly a motor base, such as a motor base of model FS80&90. The floating clamp mechanism includes: a claw arm 10, which is configured to clamp the machine base 20 to be turned over and carried; a claw arm mounting structure 30, which is configured to install and position the claw arm 10, and the claw arm mounting structure 30 can control the movement of the claw arm 10 to open or retract it; and a floating base 40, the floating base 40 includes a first bottom plate 41, a second bottom plate 42 opposite to the first bottom plate 41, and an elastic device installed between the first bottom plate 41 and the second bottom plate 42, wherein the claw arm mounting structure 30 is fixedly mounted to the second bottom plate 42, and the first bottom plate 41 has a connection structure suitable for being installed to the end 50 of the manipulator, and the elastic device can be elastically deformed when subjected to external force, so that the distance between the first bottom plate 41 and the second bottom plate 42 changes.

[0049] According to one embodiment of the present invention, the elastic device may include at least two elastic components. Figure 4 , shows an exploded schematic diagram of a floating clamp mechanism for turning over and carrying a machine base according to an exemplary embodiment of the utility model. In this embodiment, the elastic device includes four elastic components, and the four elastic components are distributed around the center of the second bottom plate 42. The second bottom plate 42 is rectangular in shape, and the four elastic components are arranged in the inner areas of the four right angles of the rectangular shape corresponding to the second bottom plate 42. The four elastic components ensure the stability of the floating clamp mechanism.

[0050] Reference Figure 4 Each elastic component includes a spring 43, a limiting column 44 and a limiting sleeve 45. The spring 43 is clamped between the first base plate 41 and the second base plate 42, and the first end of the limiting sleeve 45 is installed on the second base plate 42. The limiting column 44 passes through the limiting sleeve 45, the second base plate 42 and the spring 43 in sequence, and the first end of the limiting column 44 is fixed to the first base plate 41. In particular, a locking recess 49 is provided on the circumferential surface of the first end of the limiting column 44, and the shape of the locking recess 49 can be generally rectangular, for example. Correspondingly, a threaded hole 48 is provided on the side of the first base plate 41, so that the locking recess 49 can be supported by a screw passing through the threaded hole 48 to play a fixing role. The second end of the limiting column 44 extends outward from the side of the second base plate 42 that is opposite to the first base plate 41, and a limiting flange 47 is provided on the second end of the limiting column 44 to prevent the second end of the limiting sleeve 45 from detaching from the limiting column 44.

[0051] Reference Figure 4A corresponding mounting recess 46 for mounting each limiting sleeve 45 is arranged on the side of the second bottom plate 42 facing away from the first bottom plate 41. The size of the mounting recess 46 is suitable for receiving the first end of the limiting sleeve 45, so that the first end of the limiting sleeve 45 is sunk into the mounting recess 46, and the first end of the limiting sleeve 45 is fixed by a screw member passing through the side of the second bottom plate 42 facing the first bottom plate 41. In this embodiment, the four limiting sleeves 45 ensure that the entire mechanism will not shake perpendicular to the axis.

[0052] Reference Figure 4 The connection structure of the robot end 50 includes a mounting plate 52 with a groove 51, and one side edge of the first bottom plate 41 is configured to be suitable for being embedded in the groove 51. Figure 4 It can be seen that the groove 51 has two positioning pin holes 53 and a plurality of threaded holes, so that the side edge of the first bottom plate 41 can be firmly installed in the groove 51 by using the positioning pins and the threaded members. Figure 4 Two positioning pin holes 53 and a plurality of threaded holes are shown in the figure, and it is obvious that the number of positioning pin holes and threaded holes can be appropriately changed according to the situation. By means of the positioning pins, it can be ensured that the whole mechanism will not shake.

[0053] The floating clamp mechanism may further include a connection block 60, which is used to more firmly mount the first base plate 41 to the mounting plate 52. Figure 4 The connection block 60 includes a first mounting surface 62 and a second mounting surface which are perpendicular to each other. The first mounting surface 62 is adapted to abut against the side of the first bottom plate 41 which is opposite to the second bottom plate 42, and the second mounting surface is adapted to abut against the surface of the adjacent groove of the mounting plate 52. The connection block 60 is fixed to the first bottom plate 41 and the mounting plate 52 by screws. A pair of mounting holes 61 may also be arranged on the connection block 60, so that the connection block 60 is firmly mounted on the mounting plate 52 through a pair of connecting members to ensure that the entire mechanism does not shake.

[0054] Reference Figure 4 The first bottom plate 41 is also rectangular in shape, and the area of ​​the first bottom plate 41 is larger than the area of ​​the second bottom plate 42 . Coaxially arranged through holes are formed in the center of the first bottom plate 41 and the center of the second bottom plate 42 .

[0055] Reference Figure 4 The claw arm mounting structure 30 may include a cylinder structure to control the movement of the claw arm 10 so that the claw arm 10 can be in an open state and a contracted state. The cylinder structure is fixed to the second base plate 42 by a screw.

[0056] In order to more clearly understand the solution of the utility model, the operation process of the floating clamp mechanism for turning over and carrying the machine base is described below. According to the floating clamp mechanism of the utility model, the floating base includes two bottom plates, namely a first bottom plate 41 and a second bottom plate 42, four springs are used for buffering between the two bottom plates, and four limit columns 44 are used to limit the maximum gap, and the spring 43 is sleeved on the limit column 44 and is limited between the two bottom plates.

[0057] When moving the machine base forward (see Figure 1 ), due to gravity, the second bottom plate 42 and the limiting sleeve 45 are pressed on the limiting flanges 47 of the four limiting pillars 44. If the bottom surface of the base and the equipment are in hard contact when the manipulator is at the discharge point, the base 20, the claw arm 10, and the second bottom plate 42 can press the spring 43 upward to protect the base 20, the claw arm 10, and the equipment from being squeezed and deformed.

[0058] When turning over the transport base (see Figure 2 ), due to the action of gravity, the machine base 20, the claw arm 10, and the second bottom plate 42 press the spring 43 downward, and the gap between the limiting sleeve 45 and the limiting flange 47 of the limiting column 44 is the maximum floating margin. If the bottom surface of the machine base and the equipment have hard contact when the manipulator is at the discharge point, the machine base 20, the claw arm 10, and the second bottom plate 42 can move upward within the maximum floating margin to protect the machine base, the clamping claw, and the equipment from being squeezed and deformed.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
