[0035] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] See also Figure 1 and Figure 2 , the embodiment of the utility model discloses a universal floating sleeve device for deburring a robot, comprising a detachably connected main body 2 and a mounting seat 1, wherein the mounting seat 1 is used to connect to an industrial robot, and the main body 2 is used to connect to a pneumatic spindle; an air inlet plug 11 is fixedly provided on the main body 2 or the mounting seat 1, and the air inlet plug 11 is used to connect the main body 2 and an external air pump. The main body 2 adopts a hollow design to facilitate the installation and wiring of external tools; an air path and a piston hole are designed in the main body 2, so that the structure formed by the main body 2 and the mounting seat 1 can be regarded as a cylinder. The universal floating sleeve device also includes a pair of dustproof sleeves, which are defined as a first dustproof sleeve 3 and a second dustproof sleeve 3'. One of the first dustproof sleeve 3 and the second dustproof sleeve 3' is fixedly connected to the main body 2, and the other is fixedly connected to the mounting seat 1. It can prevent dust and water, and can also prevent debris on the surface of the workpiece from splashing into the device during the deburring process. Figure 2As shown, in this embodiment, the first dust cover 3 is fixedly connected to the main body 2, and the second dust cover 3' is fixedly connected to the mounting base 1; preferably, a first fixing plate 4 is further provided on the side of the first dust cover 3 away from the main body 2, and the bolts pass through the first fixing plate 4 and the first dust cover 3 in sequence to achieve a fixed connection between the two. Similarly, a second fixing plate 4' is further provided on the side of the second dust cover 3' away from the mounting base 1, and the bolts pass through the second fixing plate 4' and the second dust cover 3' in sequence to fix the two. Among them, "first" and "second" are only used for distinction, and do not mean that there are structural differences between the two.

[0038] For further information, please also refer to Figures 3 to 5 The universal floating sleeve device also includes a piston 10 and a floating plate 7. There are several pistons 10, which are evenly distributed in the main body 2 and are slidably connected to the piston hole in the main body 2. The piston 10 abuts against the floating plate 7 to push the floating plate 7. A guide sleeve 8 is fixedly connected to the main body 2. A rolling element is clamped between the floating plate 7 and the guide sleeve 8. The floating plate 7 can move relative to the guide sleeve 8 through the rolling element. When the pneumatic spindle is subjected to axial force during the deburring process, the two sides of the floating plate 7 are respectively subjected to the force of the piston 10 and the workpiece, and the size of the two changes and the floating plate 7 moves relative to the guide sleeve 8. When the forces on both sides of the disk 7 are uneven, the pneumatic spindle can follow the floating disk 7 to produce a floating effect in the axial direction under the action of the rolling element; when the pneumatic spindle is subjected to radial force during the deburring process, the pneumatic spindle drives the floating disk 7 to press against one side of the guide sleeve 8, and the floating disk 7 and the pneumatic spindle can rotate relative to the rolling element, producing a floating effect in the radial direction. Therefore, the deburring universal floating sleeve device of the present invention can compensate for the accuracy deviation of the robot, the deviation in the debugging process and the dimensional error of the product through axial floating and radial floating, thereby improving the deburring effect.

[0039] Furthermore, in this embodiment, the rolling element is configured as a steel ball 9, the guide sleeve 8 is configured as a circular ring, and the inner wall of the circular guide sleeve 8 is evenly provided with a plurality of guide grooves 81. The direction of the guide groove 81 is consistent with the pushing direction of the piston 10. The number of steel balls 9 is the same as the number of guide grooves 81. The steel balls 9 are movably arranged in the guide grooves 81. The floating plate 7 is also configured as a circular ring. When the guide sleeve 8 and the floating plate 7 are installed in the main body 2, the outer wall of the circular floating plate 7 is provided with a receiving portion 71. The shape and position of the receiving portion 71 match the steel balls 9. Figure 4 As shown, specifically, in this embodiment, the number of the steel balls 9 is eight, and any steel ball 9 is clamped by the accommodating portion 71 and the guide groove 81 .

[0040] Preferably, the surface of the steel ball 9, the surface of the guide groove 81 and the surface of the accommodating portion 71 are respectively provided with Teflon coating. Based on the properties of Teflon itself, the setting of the Teflon coating can effectively reduce the friction coefficient and provide wear resistance, thereby ensuring the sensitivity and effect of floating.

[0041] like Figure 3 As shown, the universal floating sleeve device of this embodiment also includes a limit plate 6, which is fixedly connected to the guide sleeve 8. The limit plate 6 is configured as a hollow ring and is provided with a limit inner edge 61. The limit inner edge 61 is used to abut the floating plate 7 to ensure that the floating plate 7 does not move excessively, thereby ensuring the maximum movement range of the pneumatic spindle; the limit plate 6 is coaxially provided with a clamping block 5, which is also configured as a ring. The clamping block 5 is fixedly connected to the floating plate 7 and is used to clamp the pneumatic spindle. A truncation opening is opened on the annular clamping block 5, which is defined as an adjustment gap 51. Adjustment holes 52 are respectively provided on the clamping blocks 5 on both sides of the adjustment gap 51. One of the two adjustment holes 52 can be passed through a bolt, and the other is provided with a nut. By positioning and adjusting the bolt and nut, the size of the adjustment gap 51 is changed to achieve a clamping effect on pneumatic spindles of different sizes.

[0042] See also Figure 6 , Figure 6 The pneumatic spindle is connected to the universal floating sleeve device of this embodiment, and the center of the floating sleeve is defined as point B, the center of the contact surface between the pneumatic spindle and the workpiece is defined as point C, the distance between point B and point C is R1, the distance from the point where the piston 10 applies force to the floating sleeve to point B is R2, the radial force exerted on the pneumatic spindle by the workpiece is F1, the axial thrust of the piston 10 on the floating sleeve is F2, and the axial force exerted on the pneumatic spindle by the workpiece is F3 (not shown in the figure). When F1=0 and the relative sizes of F2 and F3 change, under the action of the steel ball 9, the pneumatic spindle can follow the floating plate 7 to produce a floating effect in the axial direction; when F1*R1>F2*R2, the floating plate 7 and the pneumatic spindle installed thereon will rotate around a certain steel ball 9, producing a radial floating effect.

[0043] To sum up, in a deburring universal floating sleeve device applied to a robot of the present invention, the pneumatic spindle is connected to the main body 2, and is penetrated and detachably connected to the floating plate 7. The piston 10 pushes the floating plate 7, and the pneumatic spindle and the floating plate 7 move synchronously. When the pneumatic spindle is subjected to axial force during the deburring process, the two sides of the floating plate 7 are respectively subjected to the force of the piston 10 and the workpiece. When the sizes of the two change and the forces on both sides of the floating plate 7 are uneven, under the action of the rolling element, the pneumatic spindle can follow the floating plate 7 to produce a floating effect in the axial direction; when the pneumatic spindle is subjected to radial force during the deburring process, the pneumatic spindle drives the floating plate 7 to press against one side of the guide sleeve 8, and the floating plate 7 and the pneumatic spindle can rotate relative to the rolling element, producing a floating effect in the radial direction. Therefore, the deburring universal floating sleeve device of the present invention can compensate for the accuracy deviation of the robot, the deviation in the debugging process and the dimensional error of the product through axial floating and radial floating, thereby improving the deburring effect.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
