[0048] The auxiliary air buffering component 17 includes two outward expansion frames 1701 and two jet heads 1702.

[0049] The device uses the gravity of the part and the workbench to make the part move down continuously to contact the grinding wheel 505 to achieve grinding. This process simulates the force application state when grinding by hand, which is more conducive to controlling the grinding degree and avoiding edge defects of the part. At the same time, the grinding module 5 cooperates with the movable position fixing component 9, and an inclined grinding wheel 505 is used instead of the traditional flat grinding wheel 505, which can ensure better contact of the grinding surface and improve the grinding effect; the contact surfaces of the grinding wheel 505 and the part to be ground are both inclined, and there is an overall inclination angle, avoiding the force application state when the two contact being vertical, so as to prevent excessive kinetic energy and rebound phenomenon when the grinding wheel 505 contacts the part to be ground at a high speed of rotation.

[0050] Refer to Figure 2 、 Figure 3 and Figure 4, in a preferred embodiment, the grinding module 5 further includes a grinding wheel shaft 503. The grinding wheel shaft 503 is located inside the grinding base 502. The upper end of the grinding wheel shaft 503 is connected with a mounting plate 504 by bolts. The mounting plate 504 is rotatably connected with the grinding base 502 through a bearing. The grinding wheel 505 is connected with the mounting plate 504 by bolts. The lower end of the grinding wheel shaft 503 passes through the deflection table 501 and is connected with a wheel shaft gear 506 by bolts. A servo motor 507 is arranged beside the grinding base 502. The output end of the servo motor 507 is connected with a short shaft through a coupling. The other end of the short shaft passes through the deflection table 501 and is connected with a grinding gear 508 by bolts.

The telescopic ends of the two deflection hydraulic cylinders 511 are respectively connected with a movable head 512 by bolts. The two movable heads 512 are respectively located in the two notches of the deflection table 501 and are rotatably connected through bearings.

[0051] Specifically, when adjusting the grinding wheel 505: the deflection hydraulic cylinder 511 expands and contracts to push or pull the deflection table 501 to deflect; when performing grinding processing: the servo motor 507 drives the grinding gear 508 to rotate and mesh with the wheel shaft gear 506, and the grinding wheel shaft 503 rotates to drive the grinding wheel 505 to rotate;

[0052] In a specific application scenario, the grinding module 5 is applicable to the grinding processing link, that is, the grinding module 5 can perform edge grinding on thin strip-shaped parts by using the rotating grinding wheel 505 to realize the grinding processing of the parts; the inclined grinding wheel 505 can improve the contact effect during grinding processing. At the same time, it can effectively prevent the broken particles from being in the same horizontal plane as the grinding wheel 505 during the grinding process and entering the grinding position, resulting in damage or scratches on the parts and affecting the quality of the parts after grinding; the angle of the grinding wheel 505 is adjustable and can be adjusted according to the specifications of the parts to be ground, meeting the processing of grinding parts with different specifications and improving the applicable range of the device.

[0053] Refer to Figure 1 and Figure 2, in a preferred embodiment, a displacement seat 11 is bolted to the lower side of the lower workbench 4, and an inner seat 12 is bolted to the upper side of the base 2.

Moreover, an asynchronous motor 13 is arranged on one side of the inner seat 12 away from the lower workbench 4. A right-angle reducer 14 is arranged between the asynchronous motor 13 and the inner seat 12, and the output end of the right-angle reducer 14 is bolted to the ball screw 15.

[0054] Specifically, when the lower workbench 4 moves: start the asynchronous motor 13, drive the ball screw 15 to rotate under the conversion of the right-angle reducer 14, and the lower workbench 4 moves horizontally along with the displacement seat 11; the lower workbench 4 can perform horizontal reciprocating motion, and by adjusting the moving speed and the number of reciprocating motions of the lower workbench 4, the grinding quality can be controlled.

[0055] Refer to Figure 6 , Figure 7 and Figure 8 , in a preferred embodiment, the movable position fixing component 9 further includes a vertical frame 903.

An adjustment gear 912 is bolted to the movable position seat 902, and an adjustment motor 913 is bolted to the mounting table 901. The output end of the adjustment motor 913 is connected to a short shaft through a coupling, and the other end of the short shaft is bolted to a driving gear 914. The driving gear 914 is engaged with the adjustment gear 912 through a tooth groove.

[0056] Specifically, when installing the part: Place the part on the upper side of the placement plate 904, start the reverse motor 908 to drive the adjustment lead screw 909 to rotate, and the two clamping seats 906 approach each other until the clamping plate 907 clamps and fixes the part on the placement plate 904. Subsequently, start the pressing hydraulic cylinder 910 to extend. After the pressing plate 911 moves downward, it presses and fixes the part on the placement plate 904. Then start the adjustment motor 913 to drive the driving gear 914 to engage with the adjustment gear 912, and the movable seat 902 flips until the grinding surface of the part is parallel to the grinding wheel 505 below;

[0057] In a specific application scenario, the movable position fixing component 9 is applicable to the fixing link of thin strip-shaped parts. That is, the movable position fixing component 9 realizes the fixing of parts by means of left-right clamping and up-down pressing, which is more convenient for fixing and replacing parts and accelerates the overall efficiency of part processing; the movable seat 902 is adjustable and can be further adjusted according to the specification of the grinding surface of the part to be processed, ensuring the contact degree between the grinding surface and the grinding wheel 505 and effectively improving the grinding processing effect.

[0058] It should be noted that during the grinding process, the grinding degree of the cutting edge can also be adjusted by adjusting the flipping angle of the movable seat 902.

[0059] Refer to Figure 4 、 Figure 5 、 Figure 9 and Figure 10 , in a preferably embodiment, the gravity processing module 10 further includes a top frame 1005.

The upper end of the mounting rod 1004 passes through the round hole of the layer table 6 and is fixedly connected to the threaded mounting hole of the back seat 1001. And a sleeve 1006 is connected between the top seat and the back seat 1001 by bolts. The movable rod 1003 is slidably connected inside the sleeve 1006. A gasket is connected to the lower end of the movable rod 1003 by bolts. The spring 1007 is located outside the movable rod 1003, and the lower end of the spring 1007 is connected to the upper side of the gasket by bolts.

[0060] Specifically, before grinding: Start the cylinder 1002. The upper and lower chambers of the cylinder 1002 are connected to the atmosphere, and there is no pressure in the cylinder. The part and the upper workbench 8 move downward under the action of gravity. After the movable rod 1003 contacts the layer table 6, it moves upward in the sleeve 1006, and the spring 1007 is compressed into a buffer state until the part reaches the upper side of the grinding wheel 505 and enters the position to be processed. During grinding, since the part and the upper workbench 8 always have a downward force under the action of their own gravity, this force acts as a thrust to keep the part in contact with the grinding surface of the grinding wheel 505, so as to perform grinding.

[0061] In a specific application scenario, the gravity processing module 10 is applicable to the gravity processing link, that is, the gravity processing module 10 uses the gravity of the part and the workbench to urge the part to move downward continuously to contact the grinding wheel 505, so as to realize the grinding operation. This process simulates the force application state when grinding by hand, which is more conducive to controlling the grinding degree and avoiding edge defects of the part.

The upper end of the vertical seat 1601 is bolted with a suspension 1607. A liquid filling pipe 1608 and a liquid pumping pipe 1609 are bolted on one side of the suspension 1607 close to the back seat 1001. The liquid filling pipe 1608 and the liquid pumping pipe 1609 are respectively located directly above the liquid filling port 1605 and the liquid pumping port 1606.

The other ends of the two liquid infusion pipes 1611 are bolted to the liquid filling pipe 1608 and the liquid pumping pipe 1609 respectively.

[0063] Specifically, after the parts are weighed, they are placed and fixed, and the overall weight of the parts and the upper workbench is adjusted according to the actual weight: the overall weight of the upper workbench 8 has been determined, and the elastic coefficient of the spring 1007 is fixed. To ensure that the overall weight of the workbench and the parts is always greater than the preset value of the preset supporting weight of the spring 1007, it can be achieved by changing the weight in the weight adjustment box 1602. That is, when the parts are too light, the liquid in the liquid storage cylinder 1603 is added to the weight adjustment box 1602 by the centrifugal pump 1610. Conversely, the liquid in the weight adjustment box 1602 is extracted by the liquid extraction pipe 1609. The weight of the weight adjustment box 1602 feeds back data information through the pressure sensor 1604;

[0064] In a specific application scenario, the self-weight adjustment and adaptation module 16 is applicable to the adjustment link of changing the overall self-weight of the workbench and the parts. That is, the self-weight adjustment and adaptation module 16 adjusts the overall self-weight of the workbench and the parts by changing the amount of liquid in the weight adjustment box 1602, so as to ensure that the overall weight of the workbench and the parts is always greater than the preset supporting weight of the spring 1007, thereby ensuring the feasibility of gravity grinding processing; the setting of the self-weight adjustment and adaptation module 16 can meet the processing requirements of parts with different weights, avoid frequently replacing the spring 1007 due to different weight specifications of the parts, and improve the adaptability of part processing.

[0065] Refer to Figure 5 、 Figure 9 and Figure 10 In a preferred embodiment, the auxiliary air buffering component 17 further includes two umbrella-shaped windward plates 1703. The two outer expansion frames 1701 are located on both sides of the back seat 1001. The two umbrella-shaped windward plates 1703 are respectively located below the two outer expansion frames 1701 and are connected by bolts. Two symmetric installation round holes are opened on the layer table 6, and the two installation round holes are respectively located directly below the two windward plates. The two jet heads 1702 are respectively located inside the two installation round holes and are connected by bolts. An air pump 1704 is connected to the upper side of the side seat 3 by bolts. The air pump 1704 is provided with two exhaust interfaces, and two air delivery pipes 1705 are connected to the two exhaust interfaces by bolts. The other ends of the two air delivery pipes 1705 are respectively connected to the two jet heads 1702 by bolts.

[0066] Specifically, the auxiliary air buffering component 17 will be started synchronously with the gravity processing module 10. When the upper workbench 8 moves down to above the layer table 6, the air pump 1704 will eject pressurized gas upward through the jet head 1702 to act on the umbrella-shaped windward plate 1703, assisting in slowing down the fall of the upper workbench 8 until the upper workbench 8 stops at the position to be processed. At this time, the grinding surface of the part is close to but does not contact the grinding wheel 505; during processing, the auxiliary air buffering component will be closed, and the upper workbench 8 and the part will continue to move down under the action of gravity for grinding; during the processing, the auxiliary air buffering component 17 can also be turned on to make the part float above the grinding wheel 505, so as to observe and adjust.

[0067] In a specific application scenario, the auxiliary air buffering module is applicable to the falling link of the upper workbench 8 and the part, that is, the auxiliary air buffering module uses the high-pressure gas ejected upward to provide an upward thrust to the upper workbench 8, so that the part can float above the grinding wheel 505, avoiding the situation that the kinetic energy of the upper workbench 8 is too large when it falls and the spring 1007 cannot buffer in time, resulting in the contact and collision between the cutting edge of the part and the grinding wheel 505; after the auxiliary air buffering module is started, it can make the part float, which is convenient for personnel to observe and adjust the cutting edge of the part after grinding, and improves the operability of the grinding process.

[0068] A gravity grinding method for edge opening of thin strip-shaped parts, using a gravity grinding device for edge opening of thin strip-shaped parts as described above, includes the following steps:

[0069] Step 1: Adjust the angle of the grinding wheel 505 according to the specifications of the part to be ground (the deflecting hydraulic cylinder 511 expands and contracts to push or pull the deflecting table 501 to deflect).

[0070] Step 2: Fix the part to be ground using the active position fixing component 9 (place the part on the upper side of the placement plate 904, start the reverse motor 908 to drive the position adjustment lead screw 909 to rotate, and the two clamping seats 906 move closer to each other until the clamping plate 907 clamps and fixes the part on the placement plate 904. Then start the pressing hydraulic cylinder 910 to extend, and after the pressing plate 911 moves down, it presses and fixes the part on the placement plate 904. Then start the position adjustment motor 913 to drive the driving gear 914 to engage with the position adjustment gear 912, and the active position seat 902 flips until the grinding surface of the part is parallel to the grinding wheel 505 below). Start the self-adjusting weight adaptation module 16 according to the weight of the part (the part is weighed and then placed and fixed, and the overall weight of the part and the upper workbench is regulated according to the actual weight: the overall weight of the upper workbench 8 has been determined, and the elastic coefficient of the spring 1007 is fixed. To ensure that the overall weight of the workbench and the part is always greater than the preset value of the preset support weight of the spring 1007, it can be achieved by changing the weight in the weight adjustment box 1602. That is, when the part is too light, the liquid in the liquid storage cylinder 1603 is added to the weight adjustment box 1602 using the centrifugal pump 1610, and vice versa, the liquid in the weight adjustment box 1602 is extracted using the liquid extraction pipe 1609. The weight of the weight adjustment box 1602 feeds back data information through the pressure sensor 1604), and change the overall weight of the upper workbench 8;

[0071] Step 3: Start the gravity processing module 10 (start the cylinder 1002. The upper and lower chambers of the cylinder 1002 are connected to the atmosphere, and there is no pressure in the cylinder. The part and the upper workbench 8 move downward under the action of gravity. After the movable rod 1003 contacts the layer table 6, it moves upward in the sleeve 1006, and the spring 1007 is compressed into a buffer state until the part reaches the upper side of the grinding wheel 505 and enters the position to be processed) and the auxiliary air buffer component 17 (when the upper workbench 8 moves down above the layer table 6, the air pump 1704 will spray the pressurized gas upward through the jet head 1702 and act on the umbrella-shaped windward plate 1703 to assist in slowing down the fall of the upper workbench 8 until the upper workbench 8 stops at the position to be processed. At this time, the grinding surface of the part is close to but does not contact the grinding wheel 505), and the upper workbench 8 moves down to enter the position to be processed;

[0072] Step 4: Start the grinding module 5 to enter the grinding processing state, and turn off the auxiliary air buffer component 17. With the cooperation of the gravity processing module 10 (since the part and the upper workbench 8 always have a downward force under the action of their own gravity, this force serves as a thrust to keep the part in contact with the grinding surface of the grinding wheel 505 all the time, so as to carry out grinding), the part performs grinding processing operations (the servo motor 507 drives the grinding gear 508 to rotate and engage with the axle gear 506, and the grinding wheel shaft 503 rotates to drive the grinding wheel 505 to rotate). During the process, the lower workbench 4 moves left and right according to the set coordinates (start the asynchronous motor 13, which drives the ball screw 15 to rotate under the conversion of the right-angle reducer 14, and the lower workbench 4 moves horizontally along with the displacement seat 11).

[0073] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
