Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a precision positioning plane floating connector. Background Art

[0002] With the development of industrialization, the maturity of AI technology, and the widespread application of automated production robots, the grasping of products with deviations in position is increasingly required to be reliable.

[0003] At the current stage, the grasping work is completed by using a visual inspection system and a six-axis robot. This method is large and expensive and cannot meet all the requirements. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art and proposes the following technical solutions:

[0005] A precision positioning planar floating connector includes a planar bearing outer sleeve and a planar bearing sleeve coaxially arranged from outside to inside, the bottom of the planar bearing outer sleeve having a first platform extending inward, the top of the planar bearing sleeve having a second platform extending outward, the first platform being spaced below the second platform, a slotless planar bearing being arranged between the first and second platforms, the planar bearing outer sleeve and the planar bearing sleeve being rotatably connected via the slotless planar bearing, and a gap being provided between the planar bearing outer sleeve and the planar bearing sleeve on the horizontal plane to allow floating.

[0006] Changing the traditional bearing structure not only ensures that the plane bearing outer shell and the plane bearing shaft sleeve can rotate relative to each other, but also ensures that the two can move relative to each other on the horizontal plane. It can accurately locate them in real time during each grasping to ensure the accuracy of each grasping and avoid the problem of decreased accuracy over time.

[0007] As a preferred embodiment of the above technical solution, an upper connecting plate is connected to the top of the plane bearing sleeve, and the bottom of the upper connecting plate presses against the upper end face of the plane bearing sleeve. In the installed state, the upper connecting plate cooperates with the first platform of the plane bearing sleeve to limit the plane bearing sleeve.

[0008] By connecting the upper connecting plate and the plane bearing sleeve, the upper connecting plate can be used to cooperate with the first platform of the plane bearing sleeve to limit the position of the plane bearing sleeve, thereby preventing the plane bearing sleeve from moving on the vertical plane, and limiting the balls in the grooveless plane bearing to be squeezed by the end face at all times, thereby preventing idle rolling and displacement.

[0009] As a preferred embodiment of the above technical solution, the bottom of the plane bearing sleeve is connected to a lower connecting plate, and the top of the lower connecting plate presses against the plane bearing outer sleeve. In the installed state, the second platform of the plane bearing sleeve cooperates with the lower connecting plate to limit the plane bearing outer sleeve, and the lower connecting plate is rotatably connected to the upper connecting plate and allows relative movement on the horizontal plane.

[0010] By connecting the plane bearing sleeve and the lower connecting plate, the lower connecting plate can be used to cooperate with the second platform of the plane bearing sleeve to limit the position of the plane bearing outer sleeve, thereby preventing the plane bearing outer sleeve from moving on the vertical plane, and limiting the balls in the grooveless plane bearing to be squeezed by the end face at all times, thereby preventing idle rolling and displacement; and since the upper connecting plate and the lower connecting plate are respectively connected to the plane bearing outer sleeve and the plane bearing sleeve, the plane bearing outer sleeve and the plane bearing sleeve are rotatably connected and allow floating adjustment.

[0011] As a preferred embodiment of the above technical solution, a movable plate is arranged between the lower connecting plate and the plane bearing sleeve, and the lower connecting plate indirectly presses the plane bearing sleeve through the movable plate. The movable plate has four groups of slides evenly distributed around the axis, and the extension line of each slide intersects with the axis. The four slides form a cross structure, and each group of the slides is slidably connected with a movable sleeve. The four groups of movable sleeves are alternately connected to the plane bearing sleeve and the lower connecting plate through limit pins.

[0012] The cross structure limits the sliding track of the movable sleeve, thereby limiting the relative floating tracks of the upper connecting plate and the lower connecting plate, allowing the two to move relative to each other in the vertical direction.

[0013] As a preferred embodiment of the above technical solution, a pneumatic internal three-claw is coaxially installed in the upper connecting plate, and the output end of the pneumatic internal three-claw is inserted into the plane bearing sleeve. In the working state, the pneumatic internal three-claw expands and drives the upper connecting plate and the lower connecting plate to move relative to each other.

[0014] The plane bearing sleeve and the upper connecting plate can be forced to be coaxial by driving the pneumatic inner three-claw.

[0015] The beneficial effects of the utility model are:

[0016] In this application, the traditional bearing structure is changed to ensure that the plane bearing outer sleeve and the plane bearing shaft sleeve can rotate relative to each other, while also ensuring that the two can move relative to each other on the horizontal plane. They can be accurately positioned in real time during each grasping to ensure the accuracy of each grasping and avoid the problem of decreased accuracy over time. BRIEF DESCRIPTION OF THE DRAWINGS

In the installed state, the upper connecting plate 2 cooperates with the first platform of the plane bearing sleeve 3 to limit the plane bearing sleeve 5; by connecting the upper connecting plate 2 and the plane bearing sleeve 3, the upper connecting plate 2 can be used to cooperate with the first platform of the plane bearing sleeve 3 to limit the position of the plane bearing sleeve 5, thereby preventing the plane bearing sleeve 5 from moving on the vertical plane, and limiting the balls in the grooveless plane bearing 4 so that they can be squeezed by the end surface at all times, thereby avoiding empty rolling and displacement.
