Abstract
Description
Technical Field
[0001] The invention relates to the technical field of grinding and polishing machine equipment, and in particular to a grinding and polishing machine capable of real-time temperature control. Background Art
[0002] Most of the existing temperature-controlled polishing devices simply heat the polishing liquid, and achieve a weak effect of heating the polishing disc and the polished workpiece through the heat transfer of the polishing liquid. The overall heating effect is negligible. In addition, there is no dynamic detection of the temperature of the workpiece during the processing, and the temperature change of the workpiece cannot be adjusted according to the real-time dynamic temperature. This will have an adverse effect on the final processing surface of the workpiece and cannot achieve the expected effect.

[0046] like Figure 1 , Figure 2 As shown, a grinding and polishing machine capable of real-time temperature control comprises a box body 1, a first motor 2 is mounted inside the box body 1, a shaft 3 is fixedly connected to the output shaft of the first motor 2, a polishing disc 4 is arranged at one end of the shaft 3 away from the first motor 2, the polishing disc 4 is fixedly connected to the shaft 3, the polishing disc 4 is penetrated through the top of the box body 1, a heating disc 5 is arranged at the bottom of the polishing disc 4, the heating disc 5 is sleeved on the shaft 3, an atomizing cooling component is arranged on one side of the box body 1, an atomizing port of the atomizing cooling component is mounted on the top of the box body 1, a temperature control component is arranged on the top of the box body 1, and the temperature control component is electrically connected to the heating component and the atomizing cooling component;
[0047] The temperature control component controls the operation of the heating plate 5 and the atomizing cooling component according to the temperature of the surface of the polishing plate 4, so that the processing temperature of the workpiece can be adjusted.
[0048] The shaft 3 is driven to rotate by the first motor 2, and the polishing disk 4 is driven to rotate by the shaft 3, so that the workpiece is ground. The temperature of the surface of the polishing disk 4 is monitored by the temperature control component, and the heating disk 5 and the atomizing cooling component are controlled to work according to the temperature. When the temperature of the surface of the polishing disk 4 exceeds the temperature set by the temperature control component, the atomizing cooling component is controlled by the temperature control component, and the workpiece is cooled by the cooled water vapor. When the temperature of the surface of the polishing disk 4 is lower than the temperature set by the temperature control component, the heating disk 5 is controlled by the temperature control component, and the temperature of the heating disk 5 is transferred to the polishing disk 4 to increase the temperature, so that the processing temperature of the workpiece can be adjusted and controlled according to demand, thereby further ensuring the processing quality of the workpiece and solving the problem that the existing temperature-adjusting polishing device can only perform simple heating and cannot be adjusted according to the temperature of the workpiece.
[0049] As an optional embodiment, a storage tank 6 is provided on the top of the box body 1 , and the storage tank 6 is sleeved on the bottom of the polishing plate 4 , and a guide pipe 7 connected to one side of the box body 1 is provided inside the storage tank 6 .
[0050] For example, the housing 1 is made of corrosion-resistant metal material. In order to avoid corrosion of the housing 1 by chemical reagents in the polishing liquid, a polishing liquid storage tank 6 and a guide pipe 7 are designed on the housing 1 to avoid overflow of the polishing liquid and inconvenience in recycling and collection during polishing. At the same time, the contact part between the polishing disc 4 and the housing 1 is sealed to prevent the polishing liquid from flowing into the first motor 2 along the shaft 3, causing the first generator to burn out.
[0051] As an optional embodiment, a flat threaded heating wire 8 is provided inside the polishing disc 4, and wires 9 are connected to both ends of the heating wire 8, respectively. Each of the wires 9 is inserted into the shaft 3, and a copper sheet 10 is provided at one end of each wire 9 away from the heating wire 8, and each of the copper sheets 10 is embedded in the shaft 3. A sleeve 11 is sleeved on the shaft 3, and one end of the sleeve 11 is fixedly connected to the housing of the first motor 2. Two symmetrically distributed brushes 12 are inserted into the sleeve 11, and at least one first spring 13 is provided between each brush 12 and the sleeve 11, respectively. The two ends of each of the first springs 13 respectively abut against the brush 12 and the sleeve 11, and each of the brushes 12 is electrically connected to the temperature control component.
[0052] For example, the current is output from the temperature control component and connected to the brush 12 of the sleeve 11. The brush 12 is lifted by the internal first spring 13 and pressed on the copper sheet 10 on the shaft 3. When the polishing disk 4 rotates, the brush 12 and the copper sheet 10 are always in a tangent state, so that the heating wire inside the polishing disk 4 is energized and heated through the wire 9, thereby increasing the temperature of the surface of the polishing disk 4.
[0053] As an optional embodiment, a bearing 14 is provided at the center of the heating disk 5, and the bearing 14 is sleeved on the shaft 3. The inner ring of the bearing 14 is fixedly connected to the shaft 3. A plurality of heating tubes 15 in an annular array are embedded on the top of the heating disk 5. One end of each heating tube 15 is arranged close to the bearing 14, and the other end is arranged close to the outer circle of the heating disk 5. The bottom of the heating disk 5 is provided with a concentrically arranged negative electrode fixing ring 16 and a positive electrode fixing ring 17. A plurality of first support rods 18 are fixedly provided at the bottom of the negative electrode fixing ring 16, and each of the first support rods 18 is fixedly connected to the housing of the first motor 2. The bottom of the positive electrode fixing ring 17 is fixedly provided with a plurality of second support rods 1 9. Each of the second support rods 19 is fixedly connected to the bottom of the box body 1. Two negative electrode coils 20 are adhered to the inner top of the negative electrode fixing ring 16. Two positive electrode coils 21 are adhered to the inner top of the positive electrode fixing ring 17. A plurality of annular arrays of negative electrode guide rods 22 and a plurality of annular arrays of positive electrode guide rods 23 are penetrated through the bottom of the heating plate 5. One end of each of the negative electrode guide rods 22 is respectively fixedly connected to the heating tube 15, and the other end is penetrated through the top of the negative electrode fixing ring 16 and tangent to the two negative electrode coils 20. One end of each of the positive electrode guide rods 23 is respectively fixedly connected to the heating tube 15, and the other end is penetrated through the top of the positive electrode fixing ring 17 and tangent to the two positive electrode coils 21.
[0054] For example, the positive and negative poles of the power output from the temperature control component are respectively connected to the positive electrode coil 21 and the negative electrode coil 20 of the positive electrode fixing ring 17 and the negative electrode fixing ring 16, and the positive electrode guide rod 23 and the negative electrode guide rod 22 connected by the heating tube 15 are respectively tangentially in contact with the corresponding positive electrode coil 21 and the negative electrode coil 20, so that the heating tube 15 is energized and generates heat, and by arranging the bearing 14 on the heating plate 5, the shaft rod 3 cannot drive the heating plate 5 to rotate, thereby preventing the positive electrode guide rod 23 and the negative electrode guide rod 22 from not being able to maintain contact with the corresponding positive electrode coil 21 and the negative electrode coil 20.
[0055] As an optional embodiment, a first support plate 24 and a plurality of second springs 25 are provided inside the negative electrode fixing ring 16, and the two ends of each second spring 25 are respectively pressed against the inner bottom of the negative electrode fixing ring 16 and the first support plate 24; a second support plate 26 and a plurality of third springs 27 are provided inside the positive electrode fixing ring 17, and the two ends of each third spring 27 are respectively pressed against the inner bottom of the positive electrode fixing ring 17 and the second support plate 26; an annular groove 28 is provided at the bottom of the heating plate 5, and at least two guide wheels 29 are provided inside the annular groove 28, and each guide wheel 29 is respectively rotatably connected and mounted on one side of the box body 1; a second motor 30 is mounted inside the box body 1, and a rotating shaft 31 is fixedly provided on the output shaft of the second motor 30, and a rubber wheel 32 is fixedly provided on the end of the rotating shaft 31 away from the second motor 30, and the rubber wheel 32 is arranged in the annular groove 28, and the rubber wheel 32 is pressed against an annular wall of the annular groove 28.
[0056] For example, the third spring 27 and the second spring 25 respectively tighten the first support plate 24 and the second support plate 26, so that the positive guide rod 23 and the negative guide rod 22 of the heating tube 15 are compressed and keep in contact with the positive electric coil 21 and the negative electric coil 20, thereby ensuring that the heating tube 15 continues to work. During heating, the heating plate 5 is driven by the second motor 30, and the second motor 30 drives the rotating shaft 31 to rotate, and drives the rubber wheel 32 to rotate through the rotating shaft 31, and drives the heating plate 5 to rotate in the annular groove 28 through the rubber wheel 32, wherein the heating plate 5 and the polishing plate 4 rotate in opposite directions, thereby ensuring uniform heat distribution during heating.
[0057] As an optional embodiment, a cooling shell 33 is provided on the top of the box body 1, and the cooling shell 33 is fixedly connected to the box body 1, one end of the cooling shell 33 extends downward and is mounted on the atomizing cooling component, and a detachably connected cover plate 34 is provided on the top of the cooling shell 33, and a feed port 35 is provided on the cover plate 34. A plurality of arranged and distributed cooling fans 36 are installed on one side of the cooling shell 33 close to the atomizing cooling component, and an exhaust fan 37 corresponding to all the cooling fans 36 is provided on the other side, and a refrigeration chip 38 is provided on the side of each cooling fan 36 close to the exhaust fan 37.
[0058] For example, in order to prevent the mist generated by the atomizing cooling component from being lost too quickly, a cooling shell 33 is provided to effectively prevent the mist from quickly dispersing to the surroundings. A cover plate 34 is provided on the cooling shell 33, and a feed port 35 is provided on the cover plate 34, so that the workpiece is not interfered with by the cooling shell 33 and contacts the polishing disk 4. The heat dissipation fan 36 generates an airflow to drive the mist to act on the polishing disk 4. The exhaust fan 37 guides the hot air generated by the polishing disk 4 to be discharged. A cooling chip 38 is installed on the heat dissipation fan 36 to further reduce the temperature of the airflow and prevent the airflow temperature from being affected by the high indoor temperature.
[0059] As an optional embodiment, the atomization cooling component includes:
[0060] A first water storage tank 39, disposed inside the cooling shell 33;
[0061] A first water pump 40 is mounted on one side of the first water storage tank 39, and a water inlet of the first water pump 40 is arranged close to the bottom of the first water storage tank 39;
[0062] A shunt pipe 41 is mounted on the side wall of the box body 1, and a water inlet of the shunt pipe 41 is connected to a water outlet of the first water pump 40;
[0063] One end of a plurality of connecting pipes 42 is connected to the diverter pipe 41 , and the other end is provided with an atomizing nozzle 43 , and each of the atomizing nozzles 43 is mounted on the top of the box body 1 .
[0064] For example, the first water pump 40 is used to introduce water in the first water tank 39 into the shunt pipe 41, and then distributed to each connecting pipe 42 through the shunt pipe 41. The water in the connecting pipe 42 is converted into mist by the atomizing nozzle 43 to act on the polishing disk 4, so that the polishing disk 4 is affected by the atomized water vapor to reduce the temperature.
[0065] As an optional embodiment, a second water tank 44 is provided inside the box body 1, a second water pump 45 is mounted on one side of the second water tank 44, a water inlet of the second water pump 45 is connected to the bottom of the second water tank 44, a threaded return pipe 46 is hung inside the cooling shell 33, the return pipe 46 is fitted with the connecting pipe 42, both ends of the return pipe 46 pass through the box body 1 and are respectively connected to the water outlet of the second water pump 45 and the second water tank 44.
[0066] For example, the second water pump 45 is used to introduce water in the second water tank 44 from the water inlet of the return pipe 46, and flows back to the second water tank 44 from the water outlet to complete the water circulation work. The return pipe 46 is set in a threaded shape and hung on the box body 1, and is in close contact with each connecting pipe 42, so as to increase the water circulation process, thereby increasing the cooling time of the connecting pipe 42 and further reducing the temperature of the mist.
[0067] As an optional embodiment, the temperature control component includes:
[0068] A temperature adjustment controller 47 is mounted on the top of the box 1;
[0069] A power regulator 48 is installed inside the box 1 and is used to be electrically connected to all circuits;
[0070] At least two fixing seats 49, both surrounding the polishing disc 4 and fixedly connected to the box body 1;
[0071] At least two infrared thermometers 50 are hinged on one of the fixing seats 49 respectively.
[0072] For example, there are four infrared thermometers 50. By adjusting the angles of the four infrared thermometers 50, the temperature measuring points are evenly distributed on the grinding track of the workpiece on the polishing pad. The measured temperature information is converted into an electrical signal and transmitted to the processor of the temperature control controller 47. After receiving the temperature signal, the PID algorithm is used for control and the control signal is sent to the power regulator 48. The power regulator 48 controls the power of the cooling system and the heating system, thereby finally achieving cooling or heating of the workpiece and maintaining a constant temperature.
[0073] A temperature control method for a grinding and polishing machine capable of real-time temperature control comprises the following steps:
[0074] S1: Start the first motor 2 to drive the shaft 3 to rotate, drive the polishing disc 4 to rotate through the shaft 3, and drive the polishing pad to rotate and grind the workpiece through the polishing disc 4;
[0075] S2: Detect the surface of the polishing disc by using the infrared thermometer 50, and send the detected temperature signal to the temperature adjustment controller 47;
[0076] S3: Compare the temperature detected by the infrared thermometer 50 received by the temperature adjustment controller 47 with the target temperature to determine whether the detected temperature is greater than the target temperature. If so, use the atomization cooling component to cool the polishing plate 4. If not, use the heating plate 5 and the heating wire 8 to heat the polishing plate 4.
[0077] S4: Compare the temperature after cooling or heating with the target temperature again to determine whether the current temperature is equal to the target temperature. If so, adjust the system output power through the PID control power regulator 48 in the temperature control controller 47. If not, return to the previous step and perform cooling or heating again until it is equal to the target temperature, and adjust the system output power through the PID control power regulator 48 in the temperature control controller 47.
