Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a polishing device for the inner wall of a cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The cylinder barrel is the container that houses the piston rod for reciprocating motion. The smoothness of the piston rod's movement depends in part on the smoothness of the inner wall of the hydraulic cylinder barrel. Therefore, during the production or maintenance of hydraulic cylinder barrels, the inner wall of the hydraulic cylinder barrel needs to be polished to ensure the smooth movement of the piston rod.

[0003] Since the polishing device requires the use of polishing wheels for waxing and polishing, and the existing polishing device uses polishing wheels that require manual waxing and polishing, and polishing must be stopped when waxing, thus it cannot automatically wax and polish. Therefore, there is an urgent need for a cylinder inner wall polishing device to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a cylinder inner wall polishing device, which is achieved through the following technical solution.

[0005] The cylinder inner wall polishing device includes a first fixed frame and a second fixed frame. The second fixed frame is movably connected to one end of the first fixed frame via a movable seat. A clamping cylinder is provided on the first fixed frame, and two sets of hydraulic cylinders are connected through the outer surface of the clamping cylinder. A first sliding rod is fixedly connected to the top of the second fixed frame. A vertical plate is movably connected to one end of the first sliding rod. A bracket is fixedly connected to one side of the vertical plate. A rotating rod is rotatably connected between the bracket and the vertical plate. A polishing wheel and a first pulley are fixedly connected to both ends of the rotating rod, respectively. The device also includes a waxing mechanism. The waxing mechanism is provided with a wax block box. Wax blocks are embedded inside the wax block box, and one end of the wax block is attached to the outer surface of the polishing wheel.

[0006] Furthermore, a first servo motor is fixedly connected to the other end of the first fixing frame, and the output shaft of the first servo motor is fixedly connected to the clamping cylinder.

[0008] Furthermore, a second sliding rod is fixedly connected to both sides of the wax block box. One end of the second sliding rod is movably connected to a pressing plate, and the other end of the wax block is pressed against the pressing plate. A spring is fixedly connected to the other end of the second sliding rod, and one end of the spring is fixedly connected to the pressing plate. The wax block box is fixedly connected to the support through a connecting frame.

[0009] Furthermore, a second servo motor is fixedly connected to the top of the movable seat, and a lead screw is fixedly connected to the output shaft of the second servo motor. One end of the lead screw is connected through the vertical plate, and the vertical plate and the lead screw are threaded together.

[0025] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0026] Example:

[0027] The cylinder inner wall polishing device includes a first fixed frame 1 and a second fixed frame 3. The second fixed frame 3 is movably connected to one end of the first fixed frame 1 via a movable seat 32. A clamping cylinder 2 is provided on the first fixed frame 1. Two sets of hydraulic cylinders 21 are connected through the outer surface of the clamping cylinder 2. A first sliding rod 33 is fixedly connected to the top of the second fixed frame 3. A vertical plate 4 is movably connected to one end of the first sliding rod 33. A bracket 41 is fixedly connected to one side of the vertical plate 4. A rotating rod 42 is rotatably connected between the bracket 41 and the vertical plate 4. A polishing wheel 421 and a first pulley 422 are fixedly connected to both ends of the rotating rod 42, respectively. The device also includes a waxing mechanism. The waxing mechanism is provided with a wax block box 5. A wax block 54 is embedded inside the wax block box 5. One end of the wax block 54 is attached to the outer surface of the polishing wheel 421.

[0028] By adopting the above technical solution, when using the device, the cylinder to be processed is first placed into the clamping cylinder 2 for clamping and fixing. Then, the clamped cylinder is driven to rotate by the first servo motor 12. Then, the second servo motor 34 and the third servo motor 43 are turned on. The third servo motor 43 can drive the polishing wheel 421 connected to the rotating rod 42 to rotate. While the polishing wheel 421 is rotating, it can adhere to the wax block 54 for waxing. The second servo motor 34 can drive the vertical plate 4 to move, and the vertical plate 4 can drive the rotating polishing wheel 421 to move, so that the polishing wheel 421 automatically polishes the inner wall of the cylinder. The structure is reasonable, which facilitates automatic waxing and polishing and can improve polishing efficiency.

[0029] Specifically, the other end of the first fixed frame 1 is fixedly connected to the first servo motor 12, and the output shaft of the first servo motor 12 is fixedly connected to the clamping cylinder 2.

[0031] Specifically, a third servo motor 43 is fixedly connected to the other side of the vertical plate 4. The output shaft of the third servo motor 43 is fixedly connected to a second pulley 431, and the first pulley 422 rotates synchronously with the second pulley 431 through a transmission belt.

[0032] By adopting the above technical solution, the third servo motor 43 can drive the second pulley 431 to rotate.

The first pulley 422 can drive the polishing wheel 421 to rotate through the rotating rod 42, thereby enabling the polishing wheel 421 to perform rotary polishing on the cylinder.

[0033] Specifically, a second slide rod 51 is fixedly connected to both sides of the wax block box 5. One end of the second slide rod 51 is movably connected to a pressing plate 52, and the other end of the wax block 54 is pressed onto the pressing plate 52.

[0037] Specifically, a support plate 31 is fixedly connected to the bottom of the second fixed frame 3, and a roller is rotatably connected to one end of the support plate 31.

[0038] By adopting the above technical solution, the support plate 31 can support the second fixed frame 3, and the rollers on the second fixed frame 3 can be moved on the ground.

[0039] Specifically, a screw 11 is rotatably connected to the first fixed frame 1, and the movable seat 32 is threadedly engaged with the screw 11.

[0040] By adopting the above technical solution, rotating the screw 11 can drive the threaded movable seat 32 to slide on the first fixed frame 1, thereby facilitating the adjustment of the second pulley 431 connected on the second fixed frame 3 to move and fit against the inner wall of the cylinder to be processed.
