Description

Technical Field

[0001] This invention relates to the technical field of polishing apparatus, and in particular to a polishing apparatus and polishing method that uses a mixture of solid wax and liquid wax. Background Technology

[0002] Wax is one of the most common lubricants in polishing processes. Currently, there are two methods for metal polishing: one is to add solid wax, and the other is to add liquid wax.

[0003] Solid waxes are generally used for surfaces requiring a greater thickness of polishing material, while liquid waxes are used for smaller thicknesses. Furthermore, solid waxes have a higher concentration than liquid waxes, and frequent application to the polishing wheel increases the risk of fire and lowers safety. Excessive application of liquid wax can lead to runoff due to the high-speed rotation, which is not cost-effective and causes environmental damage. Polishing typically involves rough polishing, fine polishing, and finishing. Currently, solid waxes are generally used for rough polishing, while liquid waxes are generally used for finishing. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of existing metal polishing technologies, such as low safety and cost-effectiveness, by providing a polishing device and method that uses a mixture of solid and liquid waxes to improve safety and save costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A polishing device for using a mixture of solid and liquid wax includes an upper support frame and a lower base. An intermittent turntable is mounted on the lower base and rotatably connected to it. Several evenly distributed clamps are mounted on the intermittent turntable and rotatably connected to it. Workpieces are detachably mounted on the clamps. The upper support frame is suspended above the lower base and has several sliders of equal number to the clamps. The sliders are slidably connected to the support frame. A servo motor, a solid wax feeding device, and a liquid wax spraying device are detachably mounted on each slider. Polishing wheels, corresponding to the solid wax feeding device, the liquid wax spraying device, and the respective workpieces, are mounted on the output end of the servo motor.

[0006] The lower base is provided with an intermittent turntable, which is rotatably connected to the lower base. The intermittent turntable is provided with several evenly distributed clamps, which are rotatably connected to the intermittent turntable. Workpieces are detachably mounted on the clamps. The upper support frame is suspended on the lower base. The upper support frame is provided with several sliders of equal number to the clamps. The sliders are slidably connected to the support frame. A servo motor, a solid wax feeding device, and a liquid wax spraying device are detachably mounted on the sliders. The output end of the servo motor is provided with polishing wheels corresponding to the solid wax feeding device, the liquid wax spraying device, and the corresponding workpiece. Several polishing wheels on the sliders correspond to several workstations. The operator sets the corresponding polishing steps for different workstations through the control system; sets the ratio of solid wax to liquid wax for each workstation; and calculates the waxing cycle and interval based on the rotation speed of the intermittent turntable; sets the order of adding solid wax and liquid wax; after setting, the control system controls the solid wax feeding device and liquid wax spraying device to feed the materials according to the ratio set for each workstation, and simultaneously controls servo motor 1 to work, which drives the polishing wheel to rotate at a uniform speed. It can be seen that by using solid wax and liquid wax in a reasonable combination according to the ratio, it is beneficial to avoid frequent addition of solid wax on the cloth wheel, reducing the occurrence of accidents. At the same time, it reduces the amount of liquid wax used, thereby reducing the loss of liquid wax, ultimately achieving the goal of improving safety and saving costs.

[0007] Preferably, the liquid wax spraying device includes a heat preservation box and an air gun. The heat preservation box stores liquid wax. Both the heat preservation box and the air gun are detachably connected to the side wall of the slider. The heat preservation box is provided with a liquid outlet pipe. An electric switch valve and an electronic flow meter are detachably connected to the liquid outlet pipe. One end of the liquid outlet pipe is fixedly connected to the heat preservation box, and the other end of the liquid outlet pipe is provided with a flexible hose. The heat preservation box is connected to one end of the air gun in sequence through the liquid outlet pipe and the flexible hose. The other end of the air gun is provided with a spray nozzle. The air gun is aligned with the polishing wheel through the spray nozzle. The air gun is located on the side of the solid wax feeding device. The insulation box helps prevent the liquid wax inside from solidifying. An inlet pipe can be installed on the insulation box for adding liquid via a pump. According to the ratio set by the control system, after the control system opens the electric switch valve, the liquid wax in the insulation box is sequentially delivered to the air gun through the outlet pipe and hose. The control system then controls the air gun to spray the liquid wax onto the polishing wheel. During this process, the electronic flow meter constantly monitors the flow rate of the liquid wax in the outlet pipe. When the flow rate reaches the set ratio, a signal is sent to the control system, which promptly closes the electric switch valve. This timely and sensitive response helps improve the accuracy of the mixing ratio.

[0008] Preferably, the solid wax feeding device includes a condensation tank corresponding to the polishing wheel, the condensation tank having a rectangular cross-sectional shape. A second servo motor is detachably mounted on the side wall of the slider. The heat preservation box, the second servo motor, and the first servo motor are distributed sequentially on the slider from top to bottom. The air gun is located on the side of the second servo motor. A cooling box surrounds the outer wall of the condensation tank, the cooling box storing coolant. The cooling box is in contact with and fixedly connected to the side wall of the condensation tank. The output end of the second servo motor is fixedly connected to the side wall of the cooling box. The condensation tank is fixedly connected to a screw rod. A servo motor is detachably installed on the bottom of the condensation tank. The output end of the servo motor passes through the bottom of the condensation tank and is fixedly connected to one end of the screw rod. The other end of the screw rod is located inside the opening of the condensation tank. The insulation box is equipped with a liquid outlet pipe. One end of the liquid outlet pipe is fixedly connected to the insulation box and located on the side of the liquid outlet pipe. The other end of the liquid outlet pipe is suspended and corresponds to the condensation tank. An electric switch valve and an electronic flow meter are detachably connected to the liquid outlet pipe. Initially, the opening of the condensation tank faces downwards, aligned with the polishing wheel. When solid wax needs to be added in proportion, the control system activates servo motor two, which rotates the condensation tank and cooling box 90° clockwise, aligning the opening of the condensation tank upwards with the outlet pipe two. According to the proportion set by the control system, the control system opens electric valve two, allowing liquid wax in the insulation box to enter the condensation tank through outlet pipe two. During this process, electronic flow meter two constantly monitors the flow rate of liquid wax in outlet pipe two. When the flow rate reaches the set proportion of solid wax, a signal is sent to the control system, which promptly closes electric valve two. This timely and sensitive response improves the accuracy of the mixing ratio. Since the wax solidifies at room temperature, to accelerate the solidification process, [further steps are taken] during the cooling process. A cooling box is installed outside the condensation tank to improve work efficiency; the coolant in the cooling box can be circulated by a pipeline pump; after the liquid wax in the condensation tank solidifies, the control system controls servo motor two to drive the condensation tank and cooling box to rotate 90° in the opposite direction, so that the opening end of the condensation tank faces downward and is aligned with the polishing wheel again; the control system controls servo motor three to work, and the screw rotates to push the solidified wax forward until it contacts the polishing wheel; through this structural design, there is no need to frequently replace the solid wax manually, making the wax addition operation simple, time-saving and labor-saving, while the monitoring of flow rate by electronic flow meters one and two helps to improve the proportioning accuracy; the cross-sectional shape of the condensation tank is rectangular, which facilitates the screw to push the solid wax forward.

[0009] Preferably, the servo motor three is located on the sides of the polishing wheel and the liquid outlet pipe two, respectively. The output end of the servo motor three is equipped with a driving wheel, which meshes with a driven wheel. The driven wheel is rotatably connected to the bottom of the condensation tank and fixedly connected to the screw. The servo motor three transmits power through the driving and driven wheels, which helps to reduce the distance between the opening end of the condensation tank and the liquid outlet pipe two after the condensation tank rotates 90°. This avoids excessive distance between the liquid outlet pipe two and the condensation tank, preventing liquid wax from splashing out of the condensation tank and causing waste, thereby saving costs and improving the accuracy of the mixing ratio.

[0010] Preferably, the driven wheel is provided with a rotating shaft, one end of which is located outside the condensation tank and fixedly connected to the center of the driven wheel, and the other end of which is located inside the condensation tank and fixedly connected to the screw. The bottom of the condensation tank is provided with a through hole, and a bearing is provided inside the through hole. The rotating shaft is rotatably connected to the through hole through the bearing under the drive of the servo motor.

[0011] Preferably, the upper support frame is circular in shape, with several columns evenly distributed around its circumference. These columns are located on the sides of the slider and are fixedly connected to the outer wall of the support frame. The lower base is located within the circular structure formed by the columns. The inner wall of the upper support frame has a C-shaped groove containing several cylinders corresponding to the sliders. The cylinders are detachably connected to the C-shaped grooves, and the telescopic ends of the cylinders penetrate the side wall of the C-shaped grooves and are fixedly connected to the top of the corresponding slider. The bottom of the slider is detachably connected to a servo motor. The upper support frame has several vertical plates corresponding to the sliders, and these plates are fixedly connected to the upper support frame. The solid wax feeding device, liquid wax spraying device, and polishing wheel are all located on one side of the slider. A T-shaped guide block is fixed to the opposite side of the slider. The vertical plates have T-shaped guide grooves that match the T-shaped guide blocks. Driven by the cylinders, the sliders slide up and down on the vertical plates via the matching T-shaped guide blocks and T-shaped guide grooves. The upper support frame is fixed to the ground by several columns, so that it is suspended above the turntable; the slider slides up and down under the control of the cylinder, and is connected to the vertical plate by matching T-shaped guide blocks and T-shaped guide grooves, which helps to improve the connection strength and stability of the structure.

[0012] Preferably, a pressure sensor is provided at the bottom of the slider, and the top of the pressure sensor is detachably connected to the slider. A hanging bracket is provided on the servo motor, and the bottom of the pressure sensor is detachably connected to the servo motor via the hanging bracket. The pressure sensor is used to sense the polishing force of the polishing wheel. The amount of wax and the ratio of solid wax to liquid wax can also be adjusted by the force sensed by the pressure sensor through system settings.

[0013] Preferably, the lower base has a groove, and the intermittent turntable is located at the open end of the groove. A servo motor four is installed inside the groove. The servo motor four is detachably connected to the bottom center of the groove, and its output end is fixedly connected to the bottom center of the intermittent turntable. Driven by the servo motor four, the intermittent turntable is sealed and rotatably connected to the open end of the groove. The intermittent turntable rotates intermittently under the control of the servo motor four, which facilitates the sequential polishing of the workpieces on the turntable according to the work steps. Placing the servo motor four inside the groove provides better protection for it and also improves operational safety.

[0014] Preferably, the bottom of the intermittent turntable is equipped with several servo motors, each corresponding to a clamp. These servo motors are detachably connected to the bottom of the turntable and located within a groove. The output end of each servo motor passes through the turntable and is fixedly connected to the clamp. Positioning the servo motors within the groove provides better protection and enhances operational safety.

[0015] Preferably, the workpiece is cylindrical, with its ends folded outward to form an annular flange. A polishing surface is provided on the flange, and the polishing wheel corresponds vertically to the polishing surface. The clamp is located on top of the intermittent turntable and holds the workpiece against its inner wall. While the polishing wheel rotates at high speed, the workpiece rotates at a uniform speed under the drive of servo motor five, facilitating the polishing wheel's circumferential polishing of the flange's polishing surface.

[0016] The present invention also provides a polishing method for a polishing apparatus that uses a mixture of solid wax and liquid wax, comprising the following steps: Step 1: Mount the workpiece onto the fixture; Step two: The polishing wheels on several sliders correspond to several corresponding workstations. The operator sets the corresponding polishing steps for different workstations through the control system; sets the ratio of solid wax and liquid wax for the corresponding workstations; and calculates the waxing cycle and interval time based on the rotation speed of the intermittent turntable; and sets the order of adding solid wax and liquid wax. Step 3: The control system moves the slider down to a certain distance, so that the polishing wheel contacts the workpiece surface; Step 4: The control system controls the solid wax feeding device and the liquid wax spraying device to work according to the ratio set for the corresponding workstation, and at the same time controls the servo motor to work, and the servo motor drives the polishing wheel to rotate at a uniform speed. Step five: The intermittent turntable rotates intermittently at calculated intervals, allowing the corresponding workpieces to proceed to the next step in an orderly manner, until all polishing steps are completed. Therefore, by using solid wax and liquid wax in a reasonable ratio, it is beneficial to avoid frequent application of solid wax to the polishing wheel, reducing the occurrence of accidents. At the same time, it reduces the amount of liquid wax used, thereby reducing liquid wax loss, ultimately achieving the goals of improving safety and saving costs.

[0017] The present invention also provides a polishing method using a polishing apparatus that mixes solid wax and liquid wax, comprising the following steps: Step 1: Mount the workpiece onto the fixture; Step two: The polishing wheels on several sliders correspond to several corresponding workstations. The operator sets the corresponding polishing steps for different workstations through the control system; sets the corresponding values ​​for the pressure sensors on the corresponding workstations; and adjusts the quantity and ratio of solid wax and liquid wax according to the values. Step 3: The control system moves the slider down to a certain distance, so that the polishing wheel contacts the workpiece surface; Step 4: The control system proportionally controls the solid wax feeding device and the liquid wax spraying device to work in an alternating manner, while simultaneously controlling the servo motor to work, which drives the polishing wheel to rotate at a uniform speed. Step five: The intermittent turntable rotates intermittently according to the intervals calculated by the control system, allowing the corresponding workpieces to proceed to the next step in an orderly manner until all polishing steps are completed. A pressure sensor is used to sense the polishing force applied by the polishing wheel. Through system settings, the amount of wax added and the ratio of solid wax to liquid wax can be adjusted based on the force sensed by this sensor. This helps avoid frequent application of solid wax to the polishing wheel, reducing the occurrence of accidents. Simultaneously, it reduces the amount of liquid wax used, thus minimizing liquid wax loss, ultimately achieving the goals of improved safety and cost savings.

[0032] The specific steps for polishing using the above method are as follows: Work steps Work step name Polishing wheel 1 rough polishing Ma Lun 2 Fine polishing 1 Fine hemp wheel 3 Fine polishing 2 Fine hemp wheel 4 Kiyomitsu Cloth wheel The specific implementation of the liquid wax spraying device 8 is as follows: the heat preservation box 10 helps to prevent the internal liquid wax from solidifying; the heat preservation box 10 can be equipped with a liquid inlet pipe, and liquid is added by pumping; according to the ratio set by the control system, after the control system controls the electric switch valve 13 to open, the liquid wax in the heat preservation box 10 is sequentially transported to the air gun 11 through the liquid outlet pipe 12 and the hose 15. The control system controls the air gun 11 to spray the liquid wax onto the polishing wheel 9. During this process, the electronic flow meter 14 monitors the flow rate of the liquid wax in the liquid outlet pipe 12 at all times. When the flow rate reaches the ratio set by the liquid wax, a signal is sent to the control system, and the control system closes the electric switch valve 13 in time. The response is timely and sensitive, which helps to improve the accuracy of the mixing ratio.

[0033] The specific implementation of the solid wax feeding device 7 is as follows: In the initial state, the opening end of the condensation tank 17 faces downwards and is aligned with the polishing wheel 9. When solid wax needs to be added in proportion, the control system controls the servo motor 18 to work. The servo motor 18 drives the condensation tank 17 and the cooling box 19 to rotate 90° clockwise, so that the opening end of the condensation tank 17 faces upwards and is aligned with the liquid outlet pipe 22. According to the proportion set by the control system, the control system controls the electric switch valve 23 to open, and the liquid wax in the insulation box 10 enters the condensation tank 17 through the liquid outlet pipe 22. During this process, the electronic flow meter 24 monitors the flow rate of the liquid wax in the liquid outlet pipe 22 at all times. When the flow rate reaches the proportion set for solid wax, a signal is sent to the control system, and the control system closes the electric switch valve 23 in time. The response is timely and sensitive, which helps to improve the accuracy of the proportioning. The wax solidifies at room temperature. To accelerate the solidification process, a cooling box 19 is installed outside the condensation tank 17, which improves work efficiency. The coolant in the cooling box 19 can be circulated by a pipeline pump. After the liquid wax in the condensation tank 17 solidifies, the control system controls the servo motor 18 to rotate the condensation tank 17 and the cooling box 19 in opposite directions by 90°, so that the opening end of the condensation tank 17 faces downward and is aligned with the polishing wheel 9 again. The control system controls the servo motor 21 to work, and the screw 20 rotates to push the solidified wax forward until it contacts the polishing wheel 9. With this structural design, there is no need to frequently replace the solid wax manually, making the waxing process simple, time-saving, and labor-saving.
