[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0039] like Figures 1-17 As shown, the grinding mechanism for casting grinding equipment includes a base 1; a rotating platform 11 is provided on one side of the base 1, and the mechanism further includes:

[0040] The column 3 has a longitudinal adjustment mechanism 2 installed at its bottom, and the longitudinal adjustment mechanism 2 is installed above the base 1.

[0041] Side plate 5, there are two side plates 5, and the two side plates 5 are respectively installed to the front and back of the column 3 through two vertical adjustment mechanisms 4; a rotation adjustment mechanism is installed in the middle of the side plate 5; the rotation adjustment mechanism is a third motor 12, which drives the guide sleeve 6 to rotate, and is used to adjust the tilt angle of the first movable crossbeam 7 and the second movable crossbeam 8.

[0042] The first movable crossbeam 7 and the second movable crossbeam 8 are each fitted with a guide sleeve 6, and both the first movable crossbeam 7 and the second movable crossbeam 8 are connected to a lateral adjustment mechanism; the two guide sleeves 6 are respectively connected to the rotation adjustment mechanisms on the two side plates 5.

[0043] A rotating mechanism 15 is installed at one end of the first movable crossbeam 7 and one end of the second movable crossbeam 8;

[0044] Grinding assembly 9, which is connected to the rotating mechanism 15 on the first movable crossbeam 7;

[0045] Laser scanner 17 is connected to a rotating mechanism 15 on the second movable crossbeam 8.

[0046] like Figures 1-2 As shown, a motor is installed inside the rotating stage 11, and the motor is connected to the platform of the rotating stage 11. The motor drives the platform to rotate, causing the casting on the platform to rotate 180°. After grinding the inner cavity on one side of the casting, the other side of the casting is rotated to the base 1, and the inner cavity on the other side is ground through the structure on the base 1. This design is suitable for grinding the inner cavity of castings with a large length.

[0047] like Figure 3 As shown, the grinding assembly 9 includes a base 901; a disc cutter 902 and a bar cutter 903 are respectively mounted on the bottom and top of the base 901. An electric motor is installed in the base 901, which drives the disc cutter 902 and the bar cutter 903 to rotate for grinding.

[0048] The grinding mechanism of this invention is used for grinding the inner cavity of castings. The grinding steps for the inner cavity of castings are as follows:

[0049] 1. The casting is placed on the rotating stage 11. The longitudinal adjustment mechanism 2 drives the column 3 to move longitudinally, moving the laser scanner 17 to the side facing the casting. The transverse adjustment mechanism drives the second movable beam 8 to move laterally, allowing the laser scanner 17 to enter the casting. The laser scanner 17 scans and inspects the inner cavity of the casting. During the scanning process, the transverse adjustment mechanism, the longitudinal adjustment mechanism 2, and the rotation adjustment mechanism drive the second movable beam 8 to move laterally, longitudinally, and rotate, changing the position of the laser scanner 17. The rotation mechanism 15 drives the laser scanner 17 to rotate, facilitating a comprehensive scan of all areas of the inner cavity. When scanning castings of greater length, the rotating stage 11 rotates the casting 180°, and the above operation is repeated to scan both sides of the inner cavity. After scanning, the laser scanner 17 returns to its original position, leaving the inner cavity, while the rotating stage 11 rotates the casting 180° to its original position.

[0050] Second, the scanned data is transmitted to the external electrical control cabinet to generate the grinding trajectory.

[0051] 3. The grinding assembly 9 is moved to the side facing the casting by the longitudinal adjustment mechanism 2. The first movable crossbeam 7 is moved laterally by the transverse adjustment mechanism, so that the grinding assembly 9 is moved into the inner cavity of the casting. According to the grinding trajectory, the grinding assembly 9 is moved by the transverse adjustment mechanism, the longitudinal adjustment mechanism 2, the vertical adjustment mechanism 4 and the rotation mechanism 15, so that the disc cutter 902 grinds the four sides of the inner cavity, while the bar cutter 903 grinds the draft angle. During grinding, the tilt angle of the first movable crossbeam 7 is adjusted by rotating the adjustment mechanism to make it suitable for grinding when the upper and lower surfaces of the inner cavity are inclined. After grinding one side of the inner cavity of the casting, the casting is rotated 180° so that the un-grinded end is adjusted to one side of the base 1. The above operation is repeated to grind the entire inner cavity.

[0052] like Figure 1 As shown, the longitudinal adjustment mechanism 2 includes a first screw 201; a first motor 202 is fixed to the front side of the base 1, the output shaft of the first motor 202 is fixed to the end of the first screw 201, and the other end of the first screw 201 is rotatably connected to the top of the rear side of the base 1. A first nut seat 204 is threaded onto the first screw 201, and the first nut seat 204 is fixed to the bottom of the column 3. A first slide block 205 is also fixed to the bottom of the column 3, and the first slide block 205 is slidably connected to a first slide rail 203, which is fixed to the top of the base 1.

[0053] The first motor 202 drives the first screw 201 to rotate. The screw 201 and the first nut seat 204 are threaded together. With the sliding guidance of the first slide rail 203 and the first slide block 205, the column 3 can move longitudinally to adjust the longitudinal position of the column 3 and the structure on the column 3.

[0054] like Figure 1 and Figure 3 As shown, the vertical adjustment mechanism 4 includes a second motor 401 fixed to the top of the column 3. The output shaft of the second motor 401 is fixed with a second screw 402. The bottom end of the second screw 402 is rotatably connected to the bottom side of the column 3. A second nut seat 404 is threaded onto the second screw 402. The second nut seat 404 is fixed to the side plate 5. A second slide block 405 is fixed on the side plate 5. The second slide block 405 is slidably connected to a second slide rail 403, and the second slide rail 403 is fixed to the column 3.

[0055] The second motor 401 drives the second screw 402 to rotate. Through the threaded transmission between the second screw 402 and the second nut seat 404, and with the sliding guidance of the second slide block 405 and the second slide rail 403, the side plate 5 and the structure on the side plate 5 move vertically together.

[0056] like Figures 3-7 As shown, the lateral adjustment mechanism includes a first rack 13 and a drive mechanism 14; both the first movable crossbeam 7 and the second movable crossbeam 8 have strip-shaped grooves along their length direction, the first rack 13 is fixedly installed in the strip-shaped groove, the drive mechanism 14 includes a first frame 1401 and a second frame 1403 fixedly installed on the outer wall of the guide sleeve 6, a first gear 1405 is rotatably installed on the second frame 1403, and the first gear 1405 is meshed with the first rack 13, a fourth motor 1402 is fixedly installed on the first frame 1401, and the output shaft of the fourth motor 1402 is fixed to the first gear 1405 through a connecting shaft 1404.

[0057] The fourth motor 1402 drives the first gear 1405 to rotate through the connecting shaft 1404. Through the meshing transmission between the first gear 1405 and the first rack 13, the guide sleeve 6 provides a guiding function, so that the first movable crossbeam 7 and the second movable crossbeam 8 can move laterally.

[0058] The fourth motor, 1402, is a worm gear motor with self-locking properties.

[0059] The rotating mechanism 15 includes a fifth motor 1504 and a rotating shaft 1501. The fifth motors 1504 of the two rotating mechanisms 15 are respectively fixed to the ends of the first movable crossbeam 7 and the second movable crossbeam 8. The rotating shafts 1501 of the two rotating mechanisms 15 are respectively rotatably connected to the first movable crossbeam 7 and the second movable crossbeam 8. A third gear 1503 is fixedly sleeved on the output shaft of the fifth motor 1504, and a second gear 1502 is fixedly sleeved on the rotating shaft 1501. The second gear 1502 and the third gear 1503 are meshed together.

[0060] The rotating shafts 1501 of the two rotating mechanisms 15 are fixed to the base 901 of the grinding assembly 9 and the laser scanner 17, respectively. The third gear 1503 is driven to rotate by the fifth motor 1504. Through the meshing transmission between the third gear 1503 and the second gear 1502, the rotating shaft 1501 drives the grinding assembly 9 and the laser scanner 17 to rotate and adjust their positions.

[0061] like Figure 7 As shown, it also includes a protective box 10; the protective box 10 includes a box body 1001; the box body 1001 is fixed with a connecting plate 1002, the connecting plate 1002 is fixed with a guide sleeve 6 on the second movable crossbeam 8; one end of the box body 1001 is sleeved on the second movable crossbeam 8, and the other end of the box body 1001 is provided with a box cover 1003.

[0062] The protective housing 10 provides protection for the laser scanner 17 when it is not in use. When the laser scanner 17 is needed, the laser scanner 17 leaves the protective housing 10 and enters the casting through the lateral adjustment mechanism. After use, it returns to the protective housing 10 to provide dust and moisture protection.

[0063] The bottom of the box cover 1003 is provided with a first connecting seat 1004, and the first connecting seat 1004 is connected to an opening and closing mechanism 20. The bottom of the box body 1001 is fixedly installed with a protective shell 16, and the opening and closing mechanism 20 is located inside the protective shell 16.

[0064] like Figures 13-14As shown, the opening and closing mechanism 20 includes a first pulley 2003 and a second pulley 2004 rotatably mounted inside the protective shell 16. A belt 2002 is wound between the first pulley 2003 and the second pulley 2004. A shaft is fixed in the middle of the first pulley 2003, and the shaft is fixed to the first connecting seat 1004. A fourth gear 2005 is coaxially fixed to the second pulley 2004. The fourth gear 2005 is meshed with a vertical second rack 2006. A pressure column 2001 is fixed to the top of the second rack 2006. The pressure column 2001 is slidably sleeved with a groove opened at the bottom of the housing 1001. A side frame 2007 is fixed to one side of the second rack 2006. The top of the side frame 2007 is elastically connected to the bottom of the housing 1001 through a second spring 2008.

[0065] like Figure 8 As shown, the pressure column 2001 extends to the upper part of the bottom inner side of the box 1001, and the top of the pressure column 2001 is provided with an arc surface; the bottom side of the second movable crossbeam 8 is provided with a wedge-shaped surface 801 for pushing the top of the pressure column 2001.

[0066] like Figure 8 As shown, the laser scanner 17 is located inside the protective box 10 at this time, and the box cover 1003 is closed to protect the laser scanner 17. The lateral adjustment mechanism moves the second movable crossbeam 8 and the laser scanner 17 outward from the housing 1001, specifically towards the casting on the rotating platform 11. The wedge-shaped surface 801 presses down on the pressure column 2001, causing the pressure column 2001 to move downward until the bottom surface of the second movable crossbeam 8 contacts the top of the pressure column 2001. The pressure column 2001 is then pressed down to its lowest position. The pressure column 2001 drives the second rack 2006 to move downward together, stretching the second spring 2008. The second rack 2006 meshes with the fourth gear 2005, causing the second pulley 2004 to rotate. Through the belt 2002, the first pulley 2003 rotates. The first pulley 2003, through its shaft, drives the first connecting seat 1004 and the housing cover 1003 to flip together, causing one side of the housing 1001 to open automatically.

[0067] The laser scanner 17 returns to the housing 1001, and the wedge-shaped surface 801 re-fits with the top of the pressure column 2001. Through the elastic force of the second spring 2008, the second rack 2006 and the pressure column 2001 move upward together. Through the transmission of the second rack 2006 and the fourth gear 2005, as well as the transmission of the first pulley 2003, the second pulley 2004 and the belt 2002, the housing cover 1003 closes automatically.

[0068] Among them, belt 2002 is a synchronous belt, and first pulley 2003 and second pulley 2004 are synchronous pulleys.

[0069] like Figure 8 As shown, the laser scanner 17 is retracted into the housing 1001. In the protected state, there is a certain distance between the side of the laser scanner 17 away from the rotating shaft 1501 and the housing cover 1003. During the process of the pressure column 2001 being pressed down to its lowest point, the laser scanner 17 moves to consume this distance, and the laser scanner 17 does not leave the housing 1001. At the same time, by setting this distance, after the laser scanner 17 has just returned to the housing 1001, the pressure column 2001 is still fully pressed down, and the laser scanner 17 continues to move, so that one side of the laser scanner 17 forms a distance from the housing cover 1003, and the wedge-shaped surface 801 is in contact with the top of the pressure column 2001.

[0070] like Figure 8 and Figure 14 As shown, a sealing gasket is provided on one side of the box cover 1003 to fit against the side wall of the box body 1001; an inflatable sealing ring 21 is provided on the inner wall of the box body 1001 away from the box cover 1003; the inflatable sealing ring 21 is connected to an inflation / deflation mechanism 22, and the inflation / deflation mechanism 22 is fixed to the side frame 2007 of the opening and closing mechanism 20.

[0071] The inflation / deflation mechanism 22 includes a second cylinder 2202 fixedly installed on the bottom outer wall of the housing 1001; a piston disc 2203 is connected inside the second cylinder 2202, a connecting column 2201 is fixedly fixed at the bottom of the piston disc 2203, and the connecting column 2201 is slidably sleeved with the bottom end of the second cylinder 2202, the bottom end of the connecting column 2201 is fixed to the top surface of the side frame 2007, and a connecting pipe 2204 located in the bottom wall of the housing 1001 is fixedly connected to the top of the second cylinder 2202, and the connecting pipe 2204 is fixedly connected to the inflation sealing ring 21.

[0072] When the cover 1003 closes one side of the box body 1001, the pressure column 2001 and the side frame 2007 are in a high position, so that the piston disc 2203 is in a high position inside the second cylinder 2202, so that the gas inside the second cylinder 2202 is pushed into the inflation sealing ring 21, and the inflation sealing ring 21 is in an expanded state to ensure a seal.

[0073] When the box cover 1003 is opened, the pressure column 2001 moves downward, and the connecting column 2201 and piston disc 2203 move downward together through the side frame 2007. This causes the second cylinder 2202 to draw gas from the inflation seal ring 21 through the connecting pipe 2204, causing the inflation seal ring 21 to contract. This reduces the friction between the subsequent lateral movement of the second movable crossbeam 8 and the inflation seal ring 21, thereby reducing the wear caused.

[0074] When the cover 1003 is closed, the pressure column 2001 moves upward, causing the connecting column 2201 and the piston disc 2203 to move upward together, so that the gas in the second cylinder 2202 is injected into the inflation sealing ring 21 through the connecting pipe 2204, causing the inflation sealing ring 21 to expand to ensure sealing.

[0075] like Figure 7 As shown, it also includes an air supply mechanism 19; the air supply mechanism 19 is connected to two air blowing covers 18, which are respectively disposed on one side of the first objective lens 1701 and the second objective lens 1702 on the laser scanner 17. The air supply mechanism 19 supplies airflow into the air blowing covers 18, and the airflow is ejected through the air blowing covers 18 to blow away dust or dirt on the first objective lens 1701 and the second objective lens 1702, ensuring the effectiveness of their scanning and detection.

[0076] like Figures 9-11 As shown, the air supply mechanism 19 includes a first cylinder 1901; a second connecting seat 1902 is fixedly installed on the first cylinder 1901 and fixed to the bottom of the laser scanner 17; a movable cylinder 1913 is provided inside the first cylinder 1901; a first spring 1914 is provided inside the movable cylinder 1913; the movable cylinder 1913 is elastically connected to the first cylinder 1901 through the first spring 1914; a piston sleeve 1915 is fixedly sleeved on one end of the movable cylinder 1913 and is connected to the first cylinder 1901; a first one-way valve 1904 and a second one-way valve 1905 are installed on one side of the first cylinder 1901; a filter 1906 is connected to the second one-way valve 1905; and an air outlet pipe 1903 is fixedly connected to the first one-way valve 1904. The air outlet pipe 1903 is fixedly connected to two blower covers 18.

[0077] like Figure 12 As shown, the outer wall of the movable cylinder 1913 is slidably sleeved with the first cylinder 1901. A connecting rod 1907 is fixed to one end of the movable cylinder 1913. A magnetic seat 1908 is fixed to the bottom of the connecting rod 1907. A bottom groove 10011 is provided on the bottom inner wall of the box 1001. The bottom groove 10011 is open on the side near the box cover 1003 and at the top. A guide ring 1909 is fixed in the bottom groove 10011. A stop 1911 is slidably installed in the bottom groove 10011. An iron seat 1912 is fixed to the stop 1911 through a guide rod 1910. The iron seat 1912 is magnetically connected to the magnetic seat 1908. The guide rod 1910 is slidably sleeved with the guide ring 1909.

[0078] With the cover 1003 closed, the air supply mechanism 19... Figures 11-12As shown; during the opening of the box cover 1003, the laser scanner 17 and the second movable crossbeam 8 move together, the laser scanner 17 and the air supply mechanism 19 on the laser scanner 17 move together, and the magnetic seat 1908 and the iron seat 1912 are in a magnetic attraction state. The magnetic seat 1908 drives the iron seat 1912, the guide rod 1910 and the stop seat 1911 to move together until the stop seat 1911 is in contact with the guide ring 1909. At this time, the box cover 1003 has been opened; then the laser scanner 17 continues to move out of the box body 1001. The magnetic seat 1908 and the iron seat 1912 still maintain a magnetic attraction state, but the stop seat 1911 is blocked by the guide ring 1909, so that the movable cylinder 1913 moves relative to the first cylinder body 1901, and the piston sleeve 1915 and the guide ring 1909 move relative to the first cylinder body 1901. The first cylinder 1901 slides relative to the first cylinder 1901. The first cylinder 1901 draws in external air through the second one-way valve 1905 and the filter 1906, and stretches the first spring 1914 until one end of the piston sleeve 1915 of the movable cylinder 1913 contacts the inner wall of the end of the first cylinder 1901 and is blocked. The laser scanner 17 continues to move, the magnetic seat 1908 separates from the iron seat 1912, and the elastic force of the first spring 1914 resets the movable cylinder 1913 and the piston sleeve 1915, so that the gas in the first cylinder 1901 is pushed out. The gas passes through the first one-way valve 1904 and the air outlet pipe 1903 in sequence and enters the blower hood 18. The blower hood 18 blows and cleans the first objective lens 1701 and the second objective lens 1702.

[0079] The cleaning process described above is performed as the laser scanner 17 extends from inside the housing 1001, and the laser scanner 17 does not enter the casting during the cleaning process. This allows for scanning and inspection of the casting's internal cavity after cleaning.

[0080] When the laser scanner 17 returns to the housing 1001, the magnetic base 1908 contacts the iron base 1912, and the magnetic base 1908 pushes the iron base 1912, causing the iron base 1912, guide rod 1910, and stop 1911 to return to their original positions. Figure 12 The state shown.

[0081] The magnetic holder 1908 can use a permanent magnet.
