DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the present invention will be explained clearly below in conjunction with the drawings in the embodiments of the present invention; it will be described completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 11A clutch pressure plate surface grinding device comprises a body 1, a rotary positioning seat 2 for driving the pressure plate to turn over is installed on the body 1, a positioning assembly 3 for positioning and fixing the pressure plate is installed on the rotary positioning seat 2, a cleaning assembly 4 for cleaning the surface of the pressure plate is installed on one side of the body 1, and a control assembly 5 for controlling the cleaning assembly 4 is installed on the body 1;

[0031] The machine body 1 includes a support frame 11, on which a guide rail 12 is fixedly connected, a limit plate 13 is fixedly connected to one side surface of the guide rail 12, a gear ring 14 is installed on the support frame 11, a rotary positioning seat 2 includes a lower seat body 21 and an upper seat body 22, the lower seat body 21 includes a first slide 211 slidably connected to the guide rail 12 and the limit plate 13, a first electric cylinder 212 is installed on the first slide 211, and a first threaded rod 213 rotatably connected to the first electric cylinder 212 is installed on the output end of the first electric cylinder 212, the upper seat body 22 includes a second slide 221 slidably connected to the guide rail 12 and the limit plate 13, a second drive motor 222 is installed on the second slide 221, a fixed rod 223 is fixedly connected to the output end of the second drive motor 222, and a second threaded rod 224 is installed on the fixed rod 223, two positioning components 3 are respectively installed on the first threaded rod 213 and the second threaded rod 224, and a rotary drive component is provided below the lower seat body 21.

[0032] The rotary drive assembly includes a first drive motor 214 mounted on a side wall of the first slide 211 away from the first electric cylinder 212 , and a drive gear 215 meshing with the ring gear 14 is fixedly connected to the output end of the first drive motor 214 .

[0033] When surface grinding is performed on the existing clutch pressure plate blank, workers are usually required to fix the pressure plate blank first, and then use a grinding machine to grind it. Since the upper and lower side surfaces and edges of the pressure plate blank need to be grinded, and the pressure plate blank is generally fixedly installed, it is necessary to undergo multiple disassembly and reinstallation and angle adjustment to complete the overall grinding of the pressure plate blank. The operation is very cumbersome, time-consuming and labor-intensive. In addition, due to the influence of frictional heat generated during the grinding process, the surface temperature of the pressure plate blank is very high, and the turning over and angle adjustment of the pressure plate blank during the grinding process require workers to contact it, which may cause burns and pose a safety hazard.

[0034] In order to solve the above problems, the present invention is provided with a machine body 1, a rotatable positioning seat 2 and a positioning assembly 3. Before grinding the pressure plate blank, the first electric cylinder 212 is first controlled to shorten, and the output end of the first electric cylinder 212 drives the first threaded rod 213 and the positioning assembly 3 installed on the first threaded rod 213 to move downward until there is enough space between the first threaded rod 213 on the lower seat body 21 and the second threaded rod 224 on the upper seat body 22 to put the pressure plate blank in, and then the worker holds the pressure plate blank and places it on the positioning assembly 3 on the lower seat body 21, and then controls the first electric cylinder 212 to extend, and the first electric cylinder 212 is controlled to extend. The output end of the cylinder 212 drives the first threaded rod 213 and the positioning assembly 3 thereon to move upward together until the pressure plate blank is clamped and fixed between the two positioning assemblies 3 on the first threaded rod 213 and the second threaded rod 224, completing the positioning and fixing of the pressure plate blank. At this time, the pressure plate blank is in a horizontal state with the front side facing upward, and the second drive motor 222 is started. The output end of the second drive motor 222 drives the fixing rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank that is clamped and fixed between the two positioning assemblies 3 to rotate, and the front side of the pressure plate blank is polished using a polishing machine;

[0035] After the grinding of the front side of the pressure plate blank is completed, when the grinding position needs to be changed, the first drive motor 214 is started, and the output end of the first drive motor 214 drives the drive gear 215 to rotate, and the lower seat body 21 is driven to rotate around the support frame 11 by means of the meshing connection between the drive gear 215 and the gear ring 14 on the support frame 11. Since the pressure plate blank is pressed and fixed between the lower seat body 21 and the upper seat body 22, the lower seat body 21, the upper seat body 22 and the pressure plate blank are fixed as a whole at this time. Therefore, when the lower seat body 21 rotates around the support frame 11, the entire rotary positioning seat 2 drives the pressure plate blank to rotate together, so that the pressure plate blank rotates 90 degrees, changing from a horizontal state to a vertical state, and then turns off the first drive motor 214, starts the second drive motor 222, and the output end of the second drive motor 222 drives the fixing rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank pressed and fixed between the two positioning assemblies 3 to rotate, and uses a grinding machine to grind the side and edge of the pressure plate blank. In the process of rotating from horizontal to vertical, most of the metal scraps generated in the grinding process fall off the surface of the pressure plate blank;

[0036] After the grinding of the side and edge of the pressure plate blank is completed, the first drive motor 214 is started to continue to drive the rotary positioning seat 2 and the pressure plate blank to rotate 90°, changing it from a vertical state to a horizontal state with the back facing upward, the first drive motor 214 is turned off, and the second drive motor 222 is started. The output end of the second drive motor 222 drives the fixed rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank held and fixed between the two positioning assemblies 3 to rotate, and the back of the pressure plate blank is grinded by a grinding machine. After the grinding is completed, the first drive motor 214 is started to drive the rotary positioning seat 2 and the pressure plate blank to rotate 180° to reset, and restore the horizontal state with the front facing upward. After the pressure plate blank is cooled, the first electric cylinder 212 is controlled to shorten and the pressure plate blank is taken out;

[0037] During the overall grinding of the pressure plate blank using the present invention, the grinding position of the pressure plate blank can be adjusted without multiple disassembly and reinstallation. The overall operation is simple, easy to use, time-saving and labor-saving. In addition, since workers do not need to come into contact with the pressure plate blank during the grinding process, scalding accidents can be effectively avoided.

[0038] like Figure 6 As shown, the cleaning component 4 includes a fixed plate 41, a mounting plate 15 is installed on the support frame 11, the fixed plate 41 is fixedly connected to the mounting plate 15, a multi-stage electric push rod 42 is installed on the side surface of the fixed plate 41 close to the support frame 11, a pressure rod 43 is fixedly connected to the output end of the multi-stage electric push rod 42, a scraper 44 is fixedly connected to an outer surface of the pressure rod 43, and a cooling component is installed in the pressure rod 43.

[0039] like Figure 7 and Figure 8 The cooling assembly shown includes a wiping assembly 45 , which includes a mounting groove 451 and a water storage groove 452 opened in the lower half of the pressure rod 43 . The mounting groove 451 and the water storage groove 452 are interconnected, and a water-saving assembly is arranged in the mounting groove 451 .

[0040] like Fig. 9 As shown, the water-saving component includes a rubber roller 453, which is rotatably connected in the installation groove 451. A spiral groove is opened on the outer surface of the rubber roller 453, and a spiral sponge strip 454 is installed in the groove.

[0041] A ventilation slot 46 is formed in the upper half of the pressure rod 43 , and an air inlet pipe 47 connected to the ventilation slot 46 is installed on the top of the pressure rod 43 , and an axial flow fan is installed in the air inlet pipe 47 .

[0042] During the grinding process, as the pressure plate blank is turned over, most of the metal scraps will fall down under the action of gravity. Although it is not easy for metal scraps to remain on the sides and edges of the pressure plate blank, some metal scraps will still be attached to the front and back of the pressure plate blank. In order to conveniently and effectively clean up these metal scraps, the present invention is provided with a cleaning component 4. During the entire grinding process of the pressure plate blank, the pressure plate blank will rotate 360°, so it will experience two vertical states, and the two vertical states are respectively the front and back. Towards the cleaning component 4 and the reverse side toward the cleaning component 4, whenever the pressure plate blank is in a vertical state, the multi-stage electric push rod 42 can be controlled to extend, and the output end of the multi-stage electric push rod 42 drives the pressure rod 43 to approach the vertical pressure plate blank until the scraper 44 on the pressure rod 43 is against the side surface of the pressure plate blank close to the cleaning component 4, and the second drive motor 222 is started to drive the pressure plate blank to rotate. As the pressure plate blank rotates, the scraper 44 cleans away the metal scraps attached to the side of the pressure plate blank that contacts it.

[0043] After grinding is completed, in order to allow the pressure plate blank to cool down quickly so that the worker can take out the polished pressure plate blank as soon as possible, and then put in a new pressure plate blank for the next grinding process, thereby improving the grinding efficiency, the present invention is provided with a cooling component. Whenever the pressure plate blank is in a vertical state, the scraper 44 on the cleaning component 4 is used to clean the metal scraps attached to the pressure plate blank, and the side surface of the rubber roller 453 in the mounting groove 451 is also against the pressure plate blank like the scraper 44, and the water in the water storage tank 452 is wiped onto the pressure plate blank by the water absorption of the sponge strip 454. On the surface of the plate blank, as the second drive motor 222 drives the plate blank to rotate and wipe the surface of the plate blank, the plate blank is cooled down, and the setting of the sponge strip 454 can also effectively control the water consumption and avoid unnecessary waste. With the help of the axial flow fan, the outside air is sent into the air inlet pipe 47 and blown to the surface of the plate blank from the ventilation groove 46 to further increase the cooling speed. At the same time, the scraper 44 and the rubber roller 453 against the side wall of the plate blank can also ensure and improve the accuracy of the vertical state of the plate blank, thereby improving the grinding effect of the sides and edges.

[0044] like Fig.10As shown, the control component 5 includes a base 51, a fixed block 16 is installed at the highest point of the side surface of the support frame 11 close to the gear ring 14, the base 51 is fixedly connected to the fixed block 16, a plurality of sliding grooves are opened in the base 51, and sliding rods 52 are slidably connected in the plurality of sliding grooves, and arc-shaped contact plates 53 are fixedly connected to the bottom ends of the plurality of sliding rods 52, and limiting blocks 54 are fixedly connected to the top ends of the plurality of sliding rods 52, a pressing plate 56 is fixedly connected to the side surface of the contact plate 53 close to the base 51, and a pressing plate 56 is fixedly connected to one end of the pressing plate 56 close to the base 51, and a pressure touch switch 57 facing the pressing plate 56 is installed on the bottom side surface of the base 51, and the pressure touch switch 57 is electrically connected to the multi-stage electric push rod 42.

[0045] During the grinding process of the pressure plate blank, every time the pressure plate blank is rotated to a vertical state, it is necessary to manually control the extension of the multi-stage electric push rod 42. In order to further simplify the operation and control process, the present invention is provided with a control component 5. Every time the pressure plate blank is rotated to a vertical state, the side of the pressure plate blank will contact the contact plate 53 and push the contact plate 53 upward. The upward contact plate 53 drives the spring 55 and the pressing plate 56 to move toward the pressure touch switch 57. When the pressure plate blank is rotated to a vertical state, the pressing plate 56 presses the pressure touch switch 57 under the elastic force of the spring 55, so that the pressure touch switch 57 is closed, and the multi-stage electric push rod 42 automatically starts to extend and drives the pressure rod 43, the scraper 44 and the rubber roller 453 to press against the surface of one side of the pressure plate blank. With the help of the control component 5, the cleaning component 4 can be self-started after the pressure plate blank is rotated to a vertical state, thereby simplifying the operation and control process.

[0046] like Figure 5As shown, the positioning assembly 3 includes a positioning plate 31, which is in a truncated cone shape. A mounting sleeve 32 is fixedly connected to one side wall of the positioning plate 31, and a hexagonal screw block 33 is installed on the outer wall of the mounting sleeve 32. A threaded groove penetrating the positioning plate 31 is provided in the mounting sleeve 32. The two positioning plates 31 are respectively threadedly connected to the first threaded rod 213 and the second threaded rod 224 through the threaded groove. A positioning hole 34 penetrating the positioning plate 31 is provided on the positioning plate 31. Since the positioning plates 31 are in a truncated cone shape, the two positioning plates 31 are pressed and fixed to the pressure plate blank by the contact between the outer wall and the inner edge of the pressure plate blank, and the mounting sleeve 32 and the positioning plate 31 can be driven by rotating the hexagonal screw block 33. By rotating, the positions of the two positioning components 3 on the first threaded rod 213 and the second threaded rod 224 are adjusted with the help of the threaded connection. Therefore, the present invention can be applied to the pressing, fixing and grinding of pressure plate blanks of various sizes. The setting of the positioning hole 34 can be used for the positioning adjustment between the lower seat body 21 and the upper seat body 22. When there is an angular offset between the lower seat body 21 and the upper seat body 22 instead of facing each other, a positioning rod is inserted into the positioning hole 34 on one of the positioning components 3, and then the position of the lower seat body 21 or the upper seat body 22 is adjusted until the other end of the positioning rod can be inserted into the positioning hole 34 on the other positioning component 3. At this time, the lower seat body 21 and the upper seat body 22 are readjusted to a facing state.

[0047] In the present invention, before grinding the pressure plate blank, the first electric cylinder 212 is controlled to shorten, and the output end of the first electric cylinder 212 drives the first threaded rod 213 and the positioning assembly 3 installed on the first threaded rod 213 to move downward until there is enough space between the first threaded rod 213 on the lower seat body 21 and the second threaded rod 224 on the upper seat body 22 to put the pressure plate blank in, and then the worker holds the pressure plate blank and places it on the positioning assembly 3 on the lower seat body 21, and then controls the first electric cylinder 212 to extend, and the output end of the first electric cylinder 212 drives the first threaded rod 213 and the positioning assembly 3 installed on the first threaded rod 213 to move downward. The rod 213 and the positioning assembly 3 thereon move upward together until the pressure plate blank is clamped and fixed between the two positioning assemblies 3 on the first threaded rod 213 and the second threaded rod 224, completing the positioning and fixing of the pressure plate blank. At this time, the pressure plate blank is in a horizontal state with the front side facing upward, and the second drive motor 222 is started. The output end of the second drive motor 222 drives the fixing rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank that is clamped and fixed between the two positioning assemblies 3 to rotate, and the front side of the pressure plate blank is polished using a polishing machine;

[0048] After the grinding of the front side of the pressure plate blank is completed, when the grinding position needs to be changed, the first drive motor 214 is started, and the output end of the first drive motor 214 drives the drive gear 215 to rotate, and the lower seat body 21 is driven to rotate around the support frame 11 by means of the meshing connection between the drive gear 215 and the gear ring 14 on the support frame 11. Since the pressure plate blank is pressed and fixed between the lower seat body 21 and the upper seat body 22, the lower seat body 21, the upper seat body 22 and the pressure plate blank are fixed as a whole at this time. Therefore, when the lower seat body 21 rotates around the support frame 11, the entire rotary positioning seat 2 drives the pressure plate blank to rotate together, so that the pressure plate blank rotates 90 degrees, changing from a horizontal state to a vertical state, and then turns off the first drive motor 214, starts the second drive motor 222, and the output end of the second drive motor 222 drives the fixing rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank pressed and fixed between the two positioning assemblies 3 to rotate, and uses a grinding machine to grind the side and edge of the pressure plate blank. In the process of rotating from horizontal to vertical, most of the metal scraps generated in the grinding process fall off the surface of the pressure plate blank;

[0049] After the grinding of the side and edge of the pressure plate blank is completed, the first drive motor 214 is started to continue to drive the rotary positioning seat 2 and the pressure plate blank to rotate 90°, changing it from a vertical state to a horizontal state with the back facing upward, the first drive motor 214 is turned off, and the second drive motor 222 is started. The output end of the second drive motor 222 drives the fixed rod 223, the second threaded rod 224 and the positioning assembly 3 thereon to rotate, thereby driving the pressure plate blank held and fixed between the two positioning assemblies 3 to rotate, and the back of the pressure plate blank is grinded by a grinding machine. After the grinding is completed, the first drive motor 214 is started to drive the rotary positioning seat 2 and the pressure plate blank to rotate 180° to reset, and restore the horizontal state with the front facing upward. After the pressure plate blank is cooled, the first electric cylinder 212 is controlled to shorten and the pressure plate blank is taken out;

[0050] During the entire grinding process of the pressure plate blank, the pressure plate blank will rotate 360°, so it will experience two vertical states, and the two vertical states are respectively the front side facing the cleaning component 4 and the back side facing the cleaning component 4. Whenever the pressure plate blank rotates to the vertical state, the side of the pressure plate blank will contact the contact plate 53 and push the contact plate 53 upward, and the upward contact plate 53 drives the spring 55 and the pressing plate 56 to move toward the pressure touch switch 57. When the pressure plate blank rotates to the vertical state, the pressing plate 56 presses the pressure touch switch 57 under the elastic force of the spring 55, so that the pressure touch switch 57 is closed, and the multi-stage electric push rod 42 automatically starts to extend and drives the pressure rod 43, the scraper 44 and the rubber roller 453 to press against the pressure plate blank. On the surface of one side of the pressure plate blank, start the second drive motor 222 to drive the pressure plate blank to rotate. As the pressure plate blank rotates, the scraper 44 cleans up the metal scraps attached to the side of the pressure plate blank that contacts it. With the help of the water absorption of the sponge bar 454, the water in the water storage tank 452 is wiped onto the surface of the pressure plate blank. As the second drive motor 222 drives the pressure plate blank to rotate, the surface of the pressure plate blank is wiped to cool the pressure plate blank. The setting of the sponge bar 454 can also effectively control the water consumption and avoid unnecessary waste. At the same time, the scraper 44 and the rubber roller 453 against the side wall of the pressure plate blank can also ensure and improve the accuracy of the vertical state of the pressure plate blank, thereby improving the grinding effect of the sides and edges.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
