DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The device for repairing workpiece out-of-tolerance nickel plating according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the device for repairing out-of-tolerance nickel plating of a workpiece according to an embodiment of the utility model may include a base plate 100, a support plate 200, a lifting device 300, a first driving cylinder 400 and a repair device 500.

[0022] Among them, a wheel 101 is arranged at the bottom of the base plate 100, and the wheel 101 is a universal wheel with a brake structure. A handle 102 is arranged on one side of the base plate 100, and relevant staff can push the base plate 100 to move the entire device to the inner hole 600 of the workpiece.

[0023] The support plate 200 is disposed above the base plate 100 and connected thereto via a lifting device 300 .

[0024] In one embodiment of the utility model, the lifting device 300 includes a scissor arm 310 and a second driving cylinder 320, wherein the scissor arm 310 connects the support plate 200 and the base plate 100, and one end of the second driving cylinder 320 is rotatably set on the base plate 100, and the other end is set on the support rod of the scissor arm 310.

[0025] It should be noted that one side of the scissor arm 310 is pivotally connected to the support plate 200 and the base plate 100 respectively, and the other side is slidingly connected to the support plate 200 and the base plate 100 respectively. When the second driving cylinder 320 pushes the scissor arm 310, the scissor arm 310 can push the support plate 200 to move upward.

[0026] A vertical plate 201 is disposed on the support plate 200 , a first driving cylinder 400 is disposed on the vertical plate 201 , and a repair device 500 is connected to a telescopic end of the first driving cylinder 400 .

[0027] The repair device 500 includes a moving frame 510, a driving motor 520 and a rolling brush structure 530. The moving frame 510 is a U-shaped frame, and the bottom of the moving frame 510 is slidably connected to the support plate 200, and one end of the moving frame 510 is connected to the first driving cylinder 400.

[0028] As a possible situation, a limiting block is provided at the bottom of the movable frame 510, a sliding groove is provided on the support plate 200, and the limiting block is slidably connected to the sliding groove.

[0029] The driving motor 520 is disposed at the other end of the moving frame 510 , and the rolling brush structure 530 is disposed on the output end of the driving motor 520 .

[0030] like Figure 2 As shown, the roller brush structure 530 includes a fixing cavity 531 , a column 532 , a pressure plate 533 , a spring 534 , a mounting frame 535 and a cleaning brush 536 .

[0031] The fixed cavity 531 is disposed at the output end of the driving motor 520 , and the column 532 is slidably connected to the fixed cavity 531 .

[0032] It can be understood that the fixing cavity 531 is hollow inside and has a through hole on the top, and the column 532 passes through the through hole and is slidably connected to the fixing cavity 531 .

[0033] The pressing plate 533 is disposed at the end of the column 532 and is disposed in the fixing cavity 531.

[0034] It should be noted that the size of the pressing plate 533 is larger than the size of the through hole, and is in contact with the inner wall of the fixing cavity 531 .

[0035] The spring 534 is disposed in the fixed cavity 531 , and two ends of the spring 534 are respectively connected to the pressure plate 533 and the bottom of the fixed cavity 531 . The mounting frame 535 is disposed at the other end of the column 532 , and the cleaning brush 536 is rotatably disposed on the mounting frame 535 .

[0036] It should be noted that when the cleaning brush 536 contacts the inner hole 600 of the workpiece, the cleaning brush 536 drives the mounting frame 535 to press down the column 532, so that the column 532 drives the pressure plate 533 to press down the spring 534, and the spring 534 is in a compressed state.

[0037] Specifically, if Figures 1 to 3 As shown, when the relevant staff is nickel-plating the inner hole 600 of the workpiece, the relevant staff first pushes the base plate 100 to the inner hole 600 of the workpiece, and starts the lifting device 300 to raise the support plate 200, that is, by controlling the second driving cylinder 320, the scissor arm 310 is pushed by the second driving cylinder 320, so that the support plate 200 moves upward.

[0038] When the repair device 500 moves to the same height as the inner hole 600 of the workpiece following the support plate 200, the relevant staff pushes the base plate 100 to move the entire device again, and determines with the naked eye that the approximate position of the repair device 500 is coaxial with the inner hole 600 of the workpiece.

[0039] Next, the relevant staff starts the first driving cylinder 400 to move the repair device 500 toward the inner hole 600 of the workpiece, and applies nickel-plated repair liquid to the cleaning brush 536. Then, by pressing the cleaning brush 536, the cleaning brush 536 moves toward the fixed cavity 531, and the roller brush structure 530 moves into the inner hole 600 of the workpiece.

[0040] The relevant staff starts the driving motor 520 so that the driving motor 520 drives the roller brush structure 530 to rotate. Then, even if the output end of the driving motor 520 is slightly eccentric (i.e., not coaxial) with the inner hole 600 of the workpiece, the cleaning brush 536 is always pressed against the inner hole 600 of the workpiece under the action of the spring 534, thereby achieving uniform repair of the inner hole 600 of the workpiece. Therefore, the work requirements are not high and the operation is easier.

[0041] In summary, the device for repairing out-of-tolerance nickel plating of workpieces according to the embodiment of the utility model can quickly perform nickel plating repair on the inner hole of the workpiece, which is more efficient, reduces manual workload, and has low requirements for the coaxiality of the inner hole and is simple to operate.
