Description

Technical Field

[0001] The utility model relates to the technical field of floating grinding, in particular to a floating mechanism and a grinding device. Background Art

[0002] To improve the uniformity of workpiece surface polishing, two methods are generally used: one is to manually perform continuous point-by-point polishing by hard-adjusting the robot arm. However, during manual operation, the polishing force at each point is uneven and the adjustment accuracy is low, resulting in low polishing efficiency. The other method is to add a pressure sensor to the end of the robot arm. The pressure sensor monitors the pressure signal in real time during the polishing process, and the robot arm then makes corresponding point adjustments based on the pressure signal. However, pressure sensors are expensive and can only be developed for a single robot model, resulting in high polishing costs. Utility Model Content

[0070] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0071] See Figure 1 The present invention provides a polishing device 1000, comprising a floating mechanism 100, a transfer mechanism 200, a polishing member 300, and a workbench 400. The transfer mechanism 200 is connected to the floating mechanism 100 to drive the floating mechanism 100. The polishing member 300 is connected to the floating mechanism 100 and is used to polish a workpiece 500. The transfer mechanism 200 and the workpiece 500 are both located on the workbench 400. In this embodiment, the transfer mechanism 200 is a robot arm.

[0072] See Figures 2 to 4 In some embodiments, the floating mechanism 100 includes a fixing seat 110 , a driving member 120 , a mounting seat 130 , an elastic member 140 and a capacitive sensor 150 . The fixed seat 110 is used to connect with the transfer mechanism 200, and the driving member 120 includes a transmission body 121, a sliding body 122 and a driving body 123. The transmission body 121 and the sliding body 122 are in transmission cooperation. The driving body 123 is arranged on the fixed seat 110 and connected to the transmission body 121, and is used to drive the transmission body 121 to drive the sliding body 122 to move closer to or away from the fixed seat 110. The mounting seat 130 includes a guide member 131 and a mounting member 132. The guide member 131 is connected to the fixed seat 110, and the mounting member 132 is slidably connected to the guide member 131 to move closer to or away from the fixed seat 110, and the mounting member 132 is connected to the polishing member 300. The elastic member 140 elastically supports between the mounting member 132 and the sliding body 122. The capacitive sensor 150 is arranged on the sliding body 122, and is used to sense the distance between the mounting member 132 and the sliding body 122 to obtain spacing information. Among them, the sliding body 122 is used to stop the mounting part 132 in the movement direction of the mounting part 132, and the driving body 123 is electrically connected to the capacitive sensor 150, and is used to drive the transmission body 121 based on the spacing information obtained by the capacitive sensor 150 to drive the sliding body 122 and the capacitive sensor 150 to move closer to or away from the mounting part 132.

[0073] It should be noted that the capacitive sensor 150 can sense the position of the mounting member 132 to obtain the distance between the mounting member 132 and the sliding body 122. Its specific working principle and working process can be directly obtained in the published literature and will not be repeated here.

[0074] In this embodiment, the driving member 120 is a screw motor, wherein the transmission body 121 is a threaded rod of the screw motor, the sliding body 122 is a slider of the screw motor, and the driving body 123 is the main body of the screw motor.

[0075] See Figure 2 and Figure 3 In some embodiments, the fixing base 110 includes a fixing member 111, a connecting member 112, and a limiting member 113. The fixing member 111 is connected to the transfer mechanism 200, one end of the connecting member 112 is connected to the fixing member 111, and the limiting member 113 is connected to the other end of the connecting member 112 and is used to mount the driving body 123.

[0076] Therefore, an installation space for installing the driving body 123 is formed between the fixing member 111 and the limiting member 113 , which reduces the difficulty of assembling the floating mechanism 100 .

[0077] In order to facilitate the electrical connection between the floating mechanism 100 and the transfer mechanism 200 , an electrical interface 111 a is provided on the side of the fixing member 111 , and the driving body 123 is electrically connected to the transfer mechanism 200 via the electrical interface 111 a .

[0078] In some embodiments, there are multiple connectors 112, and the multiple connectors 112 are arranged at equal intervals around the driving body 123. In this embodiment, there are three connectors 112.

[0079] Therefore, the above configuration can improve the stability of the fixing base 110 .

[0080] See Figure 3 and Figure 4 In some embodiments, a limiting groove 113 a is defined on one side of the limiting member 113 facing the sliding body 122 , and the sliding body 122 is movably accommodated in the limiting groove 113 a .

[0081] Therefore, the limiting groove 113 a can limit the movement of the sliding body 122 , which is beneficial to improving the stability of the movement of the sliding body 122 .

[0082] In some embodiments, the transmission body 121 is inserted into the mounting member 132 , and the elastic member 140 is sleeved on the transmission body 121 .

[0083] Therefore, through the above configuration, the elastic stability of the elastic member 140 can be improved.

[0084] In some embodiments, the guide member 131 includes a guide rod 1311 and a mounting bearing 1312. The guide rod 1311 passes through the mounting member 132 and the sliding body 122 and is connected to the fixed base 110. The mounting bearing 1312 is sleeved on the guide rod 1311 and is connected to the mounting member 132 to guide the mounting member 132 toward or away from the fixed base 110 along the guide rod 1311.

[0085] Therefore, through the above configuration, the manufacturing cost of the floating mechanism 100 can be reduced.

[0086] In this embodiment, the mounting bearing 1312 is substantially T-shaped.

[0087] In some embodiments, the guide member 131 further includes a sliding bearing 1313 . The sliding bearing 1313 is sleeved on the guide rod 1311 and connected to the sliding body 122 to guide the sliding body 122 along the guide rod 1311 toward or away from the fixing base 110 .

[0088] Therefore, through the above configuration, the manufacturing cost of the floating mechanism 100 can be reduced.

[0089] In this embodiment, the sliding bearing 1313 is substantially in a T-shaped structure.

[0090] In some embodiments, there are multiple guide members 131 , and the multiple guide members 131 are arranged at equal intervals along the periphery of the mounting member 132 .

[0091] Therefore, the plurality of guide members 131 can improve the stability of the movement of the mounting member 132 relative to the fixing base 110 .

[0092] In this embodiment, there are three guide members 131, and the three guide members 131 and the three connecting members 112 are alternately arranged along the periphery of the stopper 113. Specifically, there are three guide rods 1311, three mounting bearings 1312, and three sliding bearings 1313, and the three guide rods 1311, the three mounting bearings 1312, and the three sliding bearings 1313 correspond to each other.

[0093] See Figure 4 and Figure 5 In this embodiment, the bottom wall of the limiting groove 113a is formed with three bearing grooves 113b, which correspond one-to-one with the three guide rods 1311 and the three sliding bearings 1313. Specifically, each guide rod 1311 is movably inserted into a corresponding bearing groove 113b, and each sliding bearing 133 is movably received in a corresponding bearing groove 113b.

[0094] Therefore, the bearing groove 113 b can limit the sliding bearing 1313 in the radial direction of the sliding bearing 1313 , which is beneficial to improving the stability of the movement of the sliding bearing 1313 .

[0095] See Figure 3 and Figure 4 In some embodiments, a sliding groove 122a is defined on the side of the sliding body 122 facing the mounting member 132. The mounting member 132 includes a main body 1321 and a stopper 1322. The main body 1321 is slidably connected to the guide member 131 to move closer to or away from the sliding body 122. The main body 1321 abuts against the elastic member 140 and is connected to the polishing member 300. The periphery of the main body 1321 corresponds to the periphery of the sliding body 122 in the direction of movement of the main body 1321. The stopper 1322 is connected to one end of the main body 1321 near the sliding body 122 and is movably received in the sliding groove 122a.

[0096] Therefore, the sliding groove 122 a can form a certain limit on the limiting platform 1322 to guide the installation member 132 to move relative to the fixing seat 110 , which is beneficial to improving the stability of the movement of the installation member 132 .

[0097] In this embodiment, the capacitive sensor 150 is installed on the bottom wall of the sliding groove 122 a , and the number of the capacitive sensors 150 is three.

[0098] To facilitate the installation of the bearing 1312 , in this embodiment, the cross-section of the main body 1321 is substantially H-shaped.

[0099] To prevent the elastic member 140 from damaging the main body 1321, the mounting member 132 further includes a stabilizing plate 1323. The stabilizing plate 1323 is embedded in the main body 1321 and sleeved over the plurality of mounting bearings 1312. The stabilizing plate 1323 can limit the radial direction of the mounting bearings 1312, thereby improving the stability of the movement of the mounting bearings 1312.

[0100] See Figure 3 and Figure 4 In this embodiment, the floating mechanism 100 further includes a stopper 160. The stopper 160 is connected to the bottom wall of the limiting groove 113a and is movably disposed through the sliding body 122. The stopper 160 is electrically connected to the driving body 123. When the stopper 160 abuts against the sliding body 122, the driving body 123 stops driving the transmission body 121 and drives the sliding body 122 upward.

[0101] In the above-mentioned floating mechanism 100 and grinding device 1000, the grinding piece 300 is installed on the mounting piece 132. The grinding piece 300 grinds the workpiece 500 and drives the mounting piece 132 to move relative to the fixed seat 110. At this time, the capacitive sensor 150 senses the distance between the mounting piece 132 and the sliding body 122 to obtain spacing information. The driving body 123 drives the transmission body 121 based on the spacing information obtained by the capacitive sensor 150 to drive the sliding body 122 and the capacitive sensor 150 to move closer to or away from the mounting piece 132 to adjust the elastic force of the elastic piece 140 on the mounting piece 132, so that the grinding piece 300 installed on the mounting piece 132 maintains a stable grinding force on the workpiece 500. The above-mentioned floating mechanism 100 and grinding device 1000 have a simple structure and low manufacturing cost, which improves the grinding efficiency and reduces the grinding cost.
