Description

Technical Field

[0001] The invention relates to the technical field of mining machinery grinding, in particular to a grinding device for mining machinery production. Background Art

[0002] In the production of mining machinery, the parts that need to be polished mainly include the following categories: main shaft and transmission shaft, bearing seat and slide rail, hydraulic and pneumatic components, etc. The purpose of polishing the main shaft and transmission shaft is to eliminate surface defects (such as casting sand holes and air holes), ensure that the journal size accuracy and surface roughness meet the assembly requirements, and the purpose of polishing the hydraulic outer wall is to reduce surface roughness, reduce friction resistance, and increase the service life of seals. Polishing is mainly done by grinding machines, and there are sandpaper grinding, sanding belt grinding, emery cloth, files, vibration grinding and laser grinding.

[0003] However, at present, some machinery used in mines needs to grind the outer walls of shaft parts and hydraulic cylinder telescopic rods during production. When grinding the transmission shaft and rotating shaft parts, they are clamped by a triangular claw disk, the shaft is rotated by a driving device, and the outer wall of the shaft is grinded with a grinder. There is no straightening mechanism on the grinding machine. Some semi-finished shafts are not axially straightened before grinding, which not only increases the difficulty of grinding, but also causes uneven stress and reduces strength, which is easy to cause breakage during later use; and after grinding, the radial shake and axial movement of the shaft surface need to be measured. Since the shaft is not straightened before grinding, the measurement is not coordinated with the straightening mechanism, resulting in repeated measurements after grinding, which increases the processing time; when the outer walls of some hydraulic rod telescopic rods are ground, their ends are not provided with an axial hole similar to the end of the transmission shaft, which is difficult to fix with the triangular claw disk clamp, and it is easy to cause the telescopic rod to shake when ground by the grinder, affecting the grinding accuracy.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1-11As shown, a grinding device for mining machinery production described in the present invention includes a table 1, a straightening mechanism 4 installed on the table 1, and a measuring mechanism 5 is provided on the straightening mechanism 4; the straightening mechanism 4 includes a slide 401, a slide 401 is slidably connected to the table 1, a cylinder 3 403 is installed on the slide 401, the telescopic end of the cylinder 3 403 is fixedly connected to a fixed frame 404, a pressure plate 405 is rotatably connected to the fixed frame 404, a plurality of pressure grooves 406 with different arc peaks are equidistantly provided on the side of the pressure plate 405, a worm gear 407 is keyed to the pressure plate 405, a worm 408 is rotatably connected to the fixed frame 404, and the worm 408 is meshed with the worm gear 407; the straightening mechanism 4 also includes an auxiliary frame 402 and an adjusting rod 411, the auxiliary frame 402 is installed on the table 1, and the slide 401 and the auxiliary frame 402 are slidably connected. , an adjusting rod 411 is slidably connected to the worm 408; the straightening mechanism 4 also includes an alignment hole 1 409 and an alignment hole 2 410, and the side wall of the worm wheel 407 is equidistantly provided with a plurality of alignment holes 1 409 opposite to the center of the pressing groove 406, and an alignment hole 2 410 of the same shape and size opposite to the alignment hole 1 409 is provided at the center of the outer wall of the fixed frame 404; a driving mechanism 7 is installed on the stage 1, and the driving mechanism 7 includes a motor 3 701 and a screw rod 2 702, a motor 3 701 is installed on the side of the stage 1, and a screw rod 2 702 is rotatably connected to the stage 1, and the screw rod 2 702 is connected to the output end of the motor 3 701 through a coupling, and the screw rod 2 702 is threadedly connected to the slide 401, and two slide rods 2 703 are fixedly connected to the stage 1, and the slide rod 2 703 is slidably connected to the slide 401;After the measurement is performed by selecting the method of connecting the mounting plate 501 with the slide 401, the motor 3 701 is started to drive the screw rod 2 702 to rotate. Since the slide 401 is slidably connected to the slide rod 2 703, the slide 401 is moved on the slide rod 2 703 when the screw rod 2 rotates. As the slide 401 moves, the pressure plate 405 is driven, and the micrometer 504 on the mounting bracket 2 506 also moves. Since the measuring position of the micrometer 504 corresponds to the center position of the pressure plate 405, the error after measurement is the pressure on the shaft 304. The position corresponding to the center of the disc 405 is realized by the slide 401 simultaneously driving the pressure plate 405 and the micrometer 504 at the bottom of the cylinder 3 403 to move together, without manually moving the micrometer 504, and accurately finding the position that needs to be pressed straight. After determining the position, the base 502 is flipped over by the hinge 508 to prevent the micrometer 504 from affecting the descent of the pressure plate 405. After flipping the micrometer 504, the cylinder 3 403 is started to realize the descent of the pressure plate 405 to press the shaft 304. The error place is pressed straight. When pressing, it is necessary to manually hold the shaft 304. According to the diameter of the shaft 304, Select the specified pressing groove 406. When selecting, you only need to match the desired pressing groove 406 with the shaft body 304. Then you need to determine the fit between the pressing groove 406 and the shaft body 304 when they are pressed straight. Therefore, when adjusting the pressure plate 405, turn the adjusting rod 411 to enable the worm 408 to drive the worm wheel 407 to rotate, and the worm 408 can limit the worm wheel 407. The alignment hole 1 409 on the opposite side of the desired pressing groove 406 can be matched with the alignment hole 2 410 on the fixing frame 404. This ensures that the desired pressing groove 406 is completely fitted with the shaft body 304 when pressed straight, ensuring stability when pressed straight. To improve the accuracy of straightening, after straightening, the slide 401 is driven by the motor 3 701, and the dial indicator 504 is also flipped to fit the shaft 304. As the slide 401 moves, the error position of the shaft 304 is continuously measured, and the straightening is completed again. Polishing after straightening can improve the strength of the shaft 304 and prevent the shaft 304 from breaking during use. During straightening, the limit frame 507 can be inserted into the limit groove 515 to ensure that the two pads 505 are located on both sides of the pressure plate 405 and are symmetrical about the pressure plate 405, thereby supporting the shaft 304 and facilitating support during straightening.

[0034] Specifically, refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 11As shown, the measuring mechanism 5 includes a mounting plate 501, a mounting plate 501 is installed on the side of the slide 401, a hinge 508 is installed on the mounting plate 501, a base 502 is installed on the hinge 508, a mounting frame 1 503 is fixedly connected to the base 502 by screws, a mounting frame 2 506 is fixedly connected to the mounting frame 1 503 by screws, and a micrometer 504 is installed on the mounting frame 2 506; the measuring mechanism 5 also includes an inner rod 509, an inner rod 509 is slidably connected to the slide 401, and the end of the inner rod 509 is fixedly connected to a connecting frame 511 with an X-shaped structure, and four plug rods 512 are distributed in a rectangular shape on the connecting frame 511. A spring 510 is clamped between 09 and the slide 401, and a mounting groove 514 is provided at the center of the mounting plate 501. The mounting plate 501 is inserted between the slide 401 and the connecting frame 511 through the mounting groove 514. Four sockets 513 are provided on the mounting plate 501 and the slide 401 in a relatively rectangular shape, and the insertion rod 512 is inserted into the inside of the socket 513; the measuring mechanism 5 also includes a limiting groove 515, and the mounting frame 503 is slidably connected to the inside of the limiting groove 515. The limiting groove 515 is located at the center of the surface of the base 502, and the limiting frame 507 is inserted into the inside of the limiting groove 515. The limiting frame 507 with a T-shaped structure is fixedly connected to both sides with a pad 505;Before grinding the semi-finished shaft 304 for mining machinery, it is necessary to measure it first. When measuring, the dial indicator 504 can be connected to the slide 401, that is, the movement of the slide 401 drives the dial indicator 504 to move on the slide 401 to measure the radial shake and axial play of the shaft 304. In order to facilitate the accurate straightening of the measured error parts, the dial indicator 504 can be installed on the slide 401. When installing, the inner rod 509 When the spring 510 is pulled out partially, the distance between the connecting frame 511 and the slide 401 becomes larger. Under the premise of ensuring that the insertion rod 512 does not block the mounting plate 501, the mounting plate 501 is inserted between the connecting frame 511 and the slide 401, and the mounting groove 514 on the mounting plate 501 is inserted into the outer wall of the inner rod 509, ensuring that the insertion rod 512 corresponds to the socket 513 on the mounting plate 501 and the socket 513 on the slide 401. 1 fits, loosens the inner rod 509 and then the spring 510 expands, and the further insertion rod 512 is inserted into the mounting plate 501 and the socket 513 on the slide 401, completing the installation of the mounting plate 501. Since the mounting plate 501 and the base 502 are hinged by the hinge 508, the base 502 can be rotated to fit the surface of the platform 1, and the position of the mounting frame 1 503 is adjusted at the limit groove 515 on the base 502 and fixed by a nut. The position of the mounting frame 2 506 is adjusted on the mounting frame 1 503 and fixed by a screw. The position of the dial indicator 504 is determined and the measuring needle contacts the shaft 304. Since the shaft 304 is not fixed, the shaft 304 can be manually rotated during measurement. Since the shaft 304 and the bearing 307 roll, there will be no error caused by rolling. The mounting plate 501 can also be disassembled by separating the insertion rod 512 and the socket 513, so that the dial indicator 504 can be manually moved to measure radial shake and axial play. ;

[0035] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the platform 1 is equipped with a clamping mechanism 3, and the clamping mechanism 3 includes two fixed platforms 301. The platform 1 has two fixed platforms 301 relatively fixedly connected, and two bearings 307 are connected to the two fixed platforms 301 for relative rotation. The platform 1 is equipped with a second cylinder 302, and the telescopic end of the second cylinder 302 is fixedly connected with a push rod 303. The two groups of bearings 307 are rollingly connected with a shaft 304, and the push rod 303 is in conflict with the hole at one end of the shaft 304. The side wall of the platform 1 is equipped with a side frame 308, and the side frame 308 is equipped with a second motor 305. The second motor 305 The output end is fixedly connected with a triangular claw disk 306, and the other end of the shaft 304 is clamped on the triangular claw disk 306; a grinding mechanism 2 is installed on the platform 1, and the grinding mechanism 2 includes two supports 202, two supports 202 are relatively installed on the platform 1, and a screw rod 205 is rotatably connected between the two supports 202, and two sliding rods 204 are fixedly connected between the two supports 202. A movable plate 203 is slidably connected to the two sliding rods 204, and the movable plate 203 is threadedly connected to the screw rod 205. A cylinder 206 is installed on the movable plate 203. A grinder 207 is slidably connected to the movable plate 203, and the telescopic end of the cylinder 1 206 is fixedly connected to the grinder 207. A motor 1 201 is installed on the stand 1, and the output end of the motor 1 201 is connected to the screw rod 1 205 through a coupling; when the shaft body 304 is straightened, the limit frame 507 can be pulled out from the inside of the limit groove 515, and the two pads 505 can be removed to avoid affecting the grinding, and one end of the shaft body 304 can be fixed by the triangular claw plate 1 306, and the cylinder 2 302 is started to push the push rod 303 out, and the hole at the other end of the shaft body 304 is made to contact the push rod 303, so as to realize the straightening of the shaft body. 304 is axially fixed, and the triangular claw disk 1 306 is driven to rotate by the motor 2 305 to realize the rotation and coordination of the shaft 304 for grinding. When the shaft 304 rotates, it rolls with the two bearings 307 on the two fixed platforms 301, reducing the friction during rotation. When grinding, the grinder 207 is started, and the motor 1 201 drives the screw rod 1 205 to rotate, so that the movable plate 203 moves on the two slide bars 1 204, and the position of the grinder 207 is adjusted laterally. The grinding disk contacts the shaft 304 for grinding, and the grinder 207 can be driven by the cylinder 1 206 to move on the movable plate 203, close to or away from the shaft 304.

[0036] Specifically, refer to Figure 1 、 Figure 2 and Figure 4As shown, a polishing mechanism 6 is installed on the stand 1, and the polishing mechanism 6 includes a shell 601, and the shell 601 is fixedly connected to the stand 1. An iron sand bucket 602 is placed inside the shell 601, and the iron sand bucket 602 is located at the bottom of the side frame 308; the polishing mechanism 6 also includes a transmission shaft 604, and the side frame 308 is vertically rotatably connected to the transmission shaft 604, and a bevel gear 1 605 is keyed to the transmission shaft 604, and the output end of the motor 2 305 is fixedly connected to the bevel gear 2 606, and the bevel gear 1 605 is meshed with the bevel gear 2 606, and the bottom of the transmission shaft 604 is fixedly connected to the triangular claw plate 2 603, and the transmission shaft 604 and the circle of the iron sand bucket 602 are located on the same axis. ; When the motor 2 305 drives the triangular claw disk 1 306 to rotate, the bevel gear 2 606 at the output end of the motor 2 305 drives the bevel gear 1 605 on the transmission shaft 604 to rotate. Then, the triangular claw disk 2 603 can also rotate at this time. If it is necessary to grind the outer wall of the telescopic rod of the hydraulic cylinder used for mining machinery, the required iron sand can be poured into the iron sand bucket 602 inside the shell 601. Before the motor 2 305 is started, the telescopic rod of the hydraulic equipment can be inserted into the iron sand bucket 602 filled with iron sand and fixed by the triangular claw disk 2 603. When the motor 2 305 rotates, it drives the transmission shaft 604 to rotate, thereby realizing the grinding of the telescopic rod of the hydraulic equipment inside the iron sand. The telescopic parts of the hydraulic equipment can be quickly clamped and fixed, saving grinding time.

[0037] When the present invention is used, first, before grinding the semi-finished shaft body 304 for mining machinery, it is necessary to measure it first. When measuring, the micrometer 504 can be connected to the slide 401, that is, the movement of the slide 401 drives the micrometer 504 to move on the slide 401 to measure the radial shake and axial play of the shaft body 304. In order to facilitate the accurate straightening of the measured error part, the micrometer 504 can be installed on the slide 401. When the inner rod 509 is pulled out a part, the spring 510 contracts, and the distance between the connecting frame 511 and the slide 401 becomes larger. Under the premise of ensuring that the insertion rod 512 does not block the mounting plate 501, the mounting plate 501 is inserted between the connecting frame 511 and the slide 401, and the mounting groove 514 on the mounting plate 501 is inserted into the outer wall of the inner rod 509, ensuring that the insertion rod 512 corresponds to the socket 513 on the mounting plate 501 and the socket 513 on the slide 401. 1 is fitted with the slide 401, and after the inner rod 509 is loosened, the spring 510 is expanded, and the further insertion rod 512 is inserted into the inside of the socket 513 on the mounting plate 501 and the slide 401 to complete the installation of the mounting plate 501. Since the mounting plate 501 and the base 502 are hinged by the hinge 508, the base 502 can be rotated to fit the surface of the platform 1, and the position of the mounting frame 503 is adjusted at the limit groove 515 on the base 502 and fixed by the nut. 3. Adjust the position of the mounting bracket 506 and fix it with screws. Determine the position of the dial indicator 504 and ensure that the measuring needle contacts the shaft 304. Since the shaft 304 is not fixed, the shaft 304 can be manually rotated during measurement. Since the shaft 304 and the bearing 307 roll, there will be no error caused by rolling. The mounting plate 501 can also be disassembled by separating the insertion rod 512 from the insertion hole 513, so that the dial indicator 504 can be manually moved to measure radial runout and axial play.

[0038] Then, after measuring by connecting the mounting plate 501 to the slide 401, the motor 3 701 is started to drive the screw rod 2 702 to rotate. Since the slide 401 is slidably connected to the slide rod 2 703, the slide 401 moves on the slide rod 2 703 when the screw rod 2 rotates. As the slide 401 moves, the pressure plate 405 is driven, and the micrometer 504 on the mounting bracket 2 506 also moves. Since the measuring position of the micrometer 504 corresponds to the center position of the pressure plate 405, the place where there is an error after measurement is the shaft 304. The position corresponding to the center position of the upper pressure plate 405 is realized by the slide 401 driving the pressure plate 405 and the micrometer 504 at the bottom of the cylinder 3 403 to move together, without manually moving the micrometer 504, and accurately finding the position that needs to be pressed straight. After determining the position, the base 502 is flipped over by the hinge 508 to prevent the micrometer 504 from affecting the descent of the pressure plate 405. After flipping the micrometer 504, the cylinder 3 403 is started to realize the descent of the pressure plate 405 to press the shaft 304. The error place is pressed straight. When pressing, it is necessary to manually hold the shaft 304, and the straightness of the shaft 304 can be adjusted. The diameter of the press groove 406 is selected. When selecting, it is only necessary to match the desired press groove 406 with the shaft body 304. Then, it is necessary to determine the fit between the press groove 406 and the shaft body 304 when they are pressed straight. Therefore, when adjusting the pressure plate 405, the adjusting rod 411 is turned to realize that the worm 408 drives the worm wheel 407 to rotate, and the worm 408 can limit the worm wheel 407. The alignment hole 1 409 on the opposite side of the desired press groove 406 is matched with the alignment hole 2 410 on the fixing frame 404. This ensures that the desired press groove 406 is completely fitted with the shaft body 304 when pressed straight, and ensures stability when pressed straight. , improve the accuracy of straightening, after straightening, the slide 401 is driven by the motor 3 701, and the dial indicator 504 is also turned over to fit the shaft 304, and the error position of the shaft 304 is continuously measured as the slide 401 moves, and straightening can be done again. Polishing after straightening can improve the strength of the shaft 304 and prevent the shaft 304 from breaking during use. When straightening, the limit frame 507 can be inserted into the limit groove 515 to ensure that the two pads 505 are located on both sides of the pressure plate 405 and are symmetrical about the pressure plate 405, so as to support the shaft 304 and facilitate support during straightening;

[0039] Next, when the shaft 304 is straightened, the limit frame 507 can be pulled out from the inside of the limit groove 515, and the two pads 505 can be removed to avoid affecting the grinding. One end of the shaft 304 is fixed by the triangular claw plate 1 306, and the cylinder 2 302 is started to push the push rod 303 out. The hole at the other end of the shaft 304 is pressed against the push rod 303 to achieve axial fixation of the shaft 304. The triangular claw plate 1 306 is driven to rotate by the motor 2 305 to realize the rotation of the shaft 304 to cooperate with the grinding. When the shaft 304 rotates, it rolls with the two bearings 307 on the two fixed platforms 301, reducing the friction during rotation. When grinding, the grinder 207 is started, and the motor 201 drives the screw 205 to rotate, so that the movable plate 203 moves on the two slide bars 204, thereby achieving the horizontal adjustment of the position of the grinder 207. The grinding disc contacts the shaft 304 for grinding, and the cylinder 206 can drive the grinder 207 to move on the movable plate 203, approaching or away from the shaft 304;

[0040] Finally, when the motor 2 305 drives the triangular claw plate 1 306 to rotate, the bevel gear 2 606 at the output end of the motor 2 305 drives the bevel gear 1 605 on the transmission shaft 604 to rotate. At this time, the triangular claw plate 2 603 can also rotate. If it is necessary to grind the outer wall of the telescopic rod of the hydraulic cylinder used in mining machinery, the required iron sand can be poured into the iron sand bucket 602 inside the outer shell 601. Before the motor 2 305 is started, the telescopic rod of the hydraulic equipment can be inserted into the iron sand bucket 602 filled with iron sand, and fixed by the triangular claw plate 2 603. When the motor 2 305 rotates, it drives the transmission shaft 604 to rotate, thereby realizing the grinding of the telescopic rod of the hydraulic equipment inside the iron sand. The telescopic parts of the hydraulic equipment can be quickly clamped and fixed, saving grinding time.
