[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0049] For example, see Figures 1 to 11A multi-angle grinding device for processing a rotary joint workpiece comprises a workbench 1 and a support seat 9 rotatably mounted on the workbench 1, a sectional arm 11 is rotatably mounted on the support seat 9, a second sectional arm 12 is mounted at the end of the first sectional arm 11, and a mounting assembly for fixing the rotary joint is mounted on the second sectional arm 12; a plurality of legs are also fixed to the bottom of the workbench 1, and the legs are fixed to the bottom of the workbench 1 by bolts, which are not shown in the figure;

[0050] A support ring 10 fixed on the workbench 1, the support ring 10 is coaxially arranged with the support seat 9, a rust removal component and a polishing component are installed on the workbench 1, a groove 45 is arranged on the side of the support ring 10 facing the polishing component, and a loading and unloading component is installed on the side of the support ring 10 away from the polishing component, and the loading and unloading component cooperates with the installation component;

[0051] A driving assembly for driving the two arms 12 to rotate is installed in the support ring 10 . The driving assembly cooperates with the rust removal assembly and the polishing assembly by driving the two arms 12 to rotate.

[0052] In the embodiment of the present invention, the installation assembly is controlled to open / close by driving the loading and unloading assembly to fix the rotating joint 15 by installing the rotating joint 15 on the installation assembly and driving the installation assembly to open, so that the rotating joint 15 rotates or moves with the two-section arm 12;

[0053] After the installation of the rotary joint 15 is completed, the support seat 9 is driven to rotate by the driving assembly, so that the rotary joint 15 moves to the top of the rust removal assembly, and the rust removal assembly is used to remove the rust on the rotary joint 15. After the rust on the rotary joint 15 is cleaned, the rotary joint 15 is driven by the driving assembly to move to the polishing assembly, and the rotary joint 15 is polished by the polishing assembly;

[0054] Among them, it can be seen from the figure that the present invention is arranged for a circular distribution, which is respectively located at the twelve o'clock, three o'clock, six o'clock and nine o'clock positions. The loading and unloading assembly is at the twelve o'clock position, the rust removal assembly is at the three o'clock position, the polishing assembly is at the six o'clock position, and the nine o'clock position is the position of the laminating equipment. The laminating equipment is not shown in this application.

[0055] The mounting assembly includes at least three opening and closing members 41 arranged equidistantly around the circumference, and a slider is provided at the bottom of each of the three opening and closing members 41, and the slider is slidably matched with a slide groove provided at the end of the two-section arm 12;

[0056] The two arms 12 and the first arm 11 are both provided with assembly grooves 42, and a screw rod 38 is rotatably installed in the assembly grooves 42 of the two arms 12. The screw rod 38 passes through the two arms 12 and is inserted into the inner sides of the three opening and closing members 41. A threaded sleeve 39 threadedly matched with the screw rod 38 is sleeved on the screw rod 38, and three second rollers 40 are rotatably installed on the threaded sleeve 39 at equal intervals. The second rollers 40 roll in cooperation with the oblique surfaces provided in the opening and closing members 41;

[0057] A second gear 24 is rotatably mounted on one side of the second sectional arm 12 , and a rotating shaft of the second gear 24 is connected to the screw rod 38 via a third bevel gear set 43 .

[0058] In the embodiment of the present invention, the second gear 24 cooperates with the disassembly assembly to drive the second gear 24 to rotate clockwise / counterclockwise during the disassembly work. When the second gear 24 rotates, the screw rod 38 is driven to rotate through the third bevel gear set 43. When the screw rod 38 rotates, the screw sleeve 39 is driven to move axially along the screw rod 38 through the thread cooperation with the threaded sleeve 39. When the threaded sleeve 39 moves, the second roller 40 is driven to follow the movement. The cooperation between the second roller 40 and the inclined surface of the opening and closing member 41 drives the three opening and closing members 41 to move synchronously in the direction away from the axial direction of the screw rod 38.

[0059] The rotary joint 15 is fixed by driving the three stretching and closing members 41 away from the axial direction of the screw rod 38. During installation, the stretching and closing members 41 are sleeved on the three stretching and closing members 41, and the rotary joint 15 is limited and fixed by moving the stretching and closing members 41 away from the axis of the screw rod 38, so that the rotary joint 15 moves / rotates with the second section arm 12. During disassembly, the rotary joint 15 is released from the limit by driving the multiple stretching and closing members 41 toward the axis of the screw rod 38, and the rotary joint 15 can be removed;

[0060] It should be noted that the third bevel gear set 43 includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the screw rod 38 and the rotating shaft of the second gear 24 respectively.

[0061] The loading and unloading assembly includes a raised seat 26 fixed on the workbench 1, a rack plate 25 meshing with the second gear 24 is slidably mounted on the raised seat 26, an elastic member connected to the rack plate 25 is installed in the raised seat 26, and a handle 27 is fixed on one side of the rack plate 25;

[0062] The elastic member includes a guide rod 36 fixed in the cushion seat 26, a connecting block is slidably mounted on the guide rod 36, and a spring 37 fixed to the connecting block is sleeved on the guide rod 36;

[0063] The support ring 10 is provided with a slot for the rack plate 25 to pass through.

[0064] In the implementation of the present invention, the handle 27 is driven to move by an external force, and the rack plate 25 is driven to move when the handle 27 rotates, and the second gear 24 is driven to rotate by the movement of the rack plate 25. When the rack plate 25 moves, the spring 37 is stretched / compressed by the connecting block, so that the spring 37 reserves a certain amount of elastic potential energy. When the force driving the handle 27 and the rack plate 25 to move disappears, the rack plate 25 is driven to reset by releasing the elastic potential energy stored in the spring 37, and the second gear 24 is driven to rotate in the opposite direction accordingly.

[0065] During installation, the handle 27 is held and pushed / pulled to move the opening / closing member 41 so that the swivel joint 15 can be removed and mounted on the opening / closing member 41. After the swivel joint 15 is installed on the mounting assembly, the mounting assembly is opened by releasing the elastic potential energy stored in the spring 37, that is, when the force of pushing / pulling the handle 27 disappears, the swivel joint 15 is locked in a limited position.

[0066] It should also be noted that a rubber layer is provided on the outer wall of the tensioning and closing member 41 to prevent damage to the rotary joint 15 due to rigid contact and to prevent slipping.

[0067] The rust removal assembly includes a mounting groove 28 , in which a wire roller 14 is rotatably mounted. A third motor 13 is rotatably mounted on one side of the workbench 1 , and an output shaft of the third motor 13 is coaxially fixed with the wire roller 14 .

[0068] In the embodiment of the present invention, when the third motor 13 is working, the third motor 13 drives the wire roller 14 to rotate through the output shaft;

[0069] The driving assembly drives the rotary joint 15 to move above the wire roller 14, and drives the rotary joint 15 to rotate. The rust is removed by driving the rotary joint 15 and the wire roller 14 to rotate relative to each other. The rotation speed of the rotary joint 15 is less than;

[0070] The third motor 13 in the present invention is a high-speed DC motor.

[0071] The polishing assembly includes two conveying rollers 3 rotatably mounted on the workbench 1 , the two conveying rollers 3 are connected via a polishing belt 2 , and one of the conveying rollers 3 is connected to the driving assembly via a first transmission chain 4 .

[0072] In the embodiment of the present invention, when the driving assembly is working, the conveying roller 3 is driven to rotate by the first transmission chain 4, and when the conveying roller 3 rotates, the polishing belt 2 is driven to be conveyed;

[0073] When the driving assembly is working, the two-section arm 12 is also driven to rotate toward the polishing belt 2, and the rotary joint 15 is in a state of abutting the polishing belt 2, and the polishing belt 2 is transported to the rotary joint 15 for polishing.

[0074] Embodiment 2: The difference from Embodiment 1 is that: the driving assembly includes a first gear 23 rotatably mounted on the first truncated arm 11, the rotating shaft of the first gear 23 is connected to the rotating shaft of the second truncated arm 12 through a fourth bevel gear set 44, and the first gear 23 cooperates with a rotating assembly mounted on the workbench 1;

[0075] An angle adjustment component for driving the support seat 9 to rotate intermittently and at equal angles is installed at the bottom of the workbench 1.

[0076] In the embodiment of the present invention, when the angle adjustment assembly is working, the support seat 9 is driven to intermittently rotate at equal angles, and the second arm 12 and the first arm 11 are correspondingly driven to rotate accordingly, so that the rotary joint 15 is located on the rust removal assembly or the polishing assembly;

[0077] When the rotating component is working, it has the following two states:

[0078] State 1: When the rotary joint 15 is adjusted to above the wire roller 14 through the angle adjustment component, the first gear 23 is driven to rotate. When the first gear 23 rotates, the second sectional arm 12 and the parts installed on the second sectional arm 12 and the rotary joint 15 are driven to rotate through the fourth bevel gear set 44. When the rotary joint 15 is in contact with the wire roller 14 for rust removal, the rotary joint 15 is in a rotating state, so that the rust on the circumference of the rotary joint 15 can be evenly treated;

[0079] State 2: when the rotary joint 15 is adjusted to above the wire roller 14 by the angle adjustment assembly, the first gear 23 is driven to rotate intermittently at an equal angle, and at the same time, a section arm 11 is driven to reciprocate with the rotation connection between the section arm 11 and the support seat 9 as the rotation axis.

[0080] The angle adjustment assembly includes a driven disk 17 rotatably mounted on the bottom of the workbench 1, a plug-in block 19 is coaxially fixed on the driven disk 17, and the plug-in block 19 is inserted into a plug-in slot provided at the bottom of the support seat 9;

[0081] A driving disk 35 cooperating therewith is rotatably mounted on one side of the driven disk 17 . A fourth motor 18 is also fixed to the bottom of the workbench 1 via a support clamp 16 . The output shaft of the fourth motor 18 is coaxially fixed to the driving disk 35 .

[0082] In the embodiment of the present invention, when the fourth motor 18 is working, the output shaft drives the active disk 35 to rotate, and when the active disk 35 rotates one circle, the driven disk 17 is driven to rotate a quarter, and when the driven disk 17 rotates, the support seat 9 is driven to rotate with it through the plug-in block 19;

[0083] The active disk 35 in this embodiment adopts the Maltese cross movement in the prior art, which is a relatively mature prior art and will not be elaborated on herein.

[0084] The rotating assembly includes a first transmission rod 5, a second transmission rod 30, and a third transmission rod 33 rotatably mounted on the workbench 1, and the first transmission rod 5 is connected to one of the conveying rollers 3 through a first transmission chain 4;

[0085] A cam 21 is rotatably mounted on the workbench 1, the rotating shaft of the cam 21 is connected to one of the first transmission rods 5 through the first bevel gear set 20, and the cam 21 is also connected to the second transmission rod 30 through the third transmission chain 22, and the second transmission rod 30 is connected to the third transmission rod 33 through the second bevel gear set 32;

[0086] An incomplete gear 31 is coaxially fixed on the second transmission rod 30, and a third gear 34 is coaxially fixed on the third transmission rod 33. Both the third transmission rod 33 and the incomplete gear 31 cooperate with the first gear 23.

[0087] A first motor 7 is also fixed on the workbench 1 , and an output shaft of the first motor 7 is connected to the first transmission rod 5 via a second transmission chain 6 .

[0088] In the embodiment of the present invention, when the first motor 7 is working, the output shaft drives the first transmission rod 5 to rotate through the second transmission chain 6, and when the first transmission rod 5 rotates, the cam 21 is driven to rotate through the first bevel gear set 20, and when the cam 21 rotates, the second transmission rod 30 is driven to rotate through the third transmission chain 22, and when the second transmission rod 30 rotates, the third transmission rod 33 is driven to rotate by the second bevel gear set 32;

[0089] When the second transmission rod 30 rotates, the incomplete gear 31 is driven to rotate, and when the third transmission rod 33 rotates, the third gear 34 is driven to rotate;

[0090] When the rotary joint 15 is above the wire roller 14, the first gear 23 is in meshing with the third gear 34, so that the first gear 23 rotates. When the first gear 23 rotates, the second truncated arm 12 and the rotary joint 15 are driven to rotate through the fourth bevel gear set 44;

[0091] When the rotary joint 15 is on the polishing belt 2, it is in a state of cooperation with the incomplete gear 31. When the toothed portion of the incomplete gear 31 rotates to mesh with the first gear 23, the first gear 23 is driven to rotate. When the incomplete gear 31 is disengaged from the first gear 23, the first gear 23 stops rotating, so as to achieve the purpose of driving the rotary joint 15 to rotate intermittently at equal angles.

[0092] Preferably, in order to improve the accuracy of the equiangular intermittent drive of the incomplete gear 31, another set of Maltese cross movement is used, wherein the driving disc is coaxially fixed on the second transmission rod 30, the driven disc is rotatably mounted on the workbench 1, and a toothed ring is provided on the edge of the driven disc, and the first gear 23 is meshed with the toothed ring when the rotary joint 15 is on the polishing belt 2;

[0093] Due to the groove 45 provided on the support ring 10, when the rotary joint 15 is on the polishing belt 2, the rotary joint 15 has a force toward the polishing belt 2, so as to improve the polishing efficiency;

[0094] When the cam 21 rotates, when the protruding portion of the cam 21 faces toward the one section arm 11, the one section arm 11 is lifted up, so that the rotary joint 15 is separated from the contact with the polishing belt 2, and when separated, the one section arm 11 is driven to rotate once through the cooperation between the incomplete gear 31 and the first gear 23;

[0095] The cam 21 also has a first roller 29 rotatably mounted on the raised portion thereof, and the first roller 29 can reduce the friction force with the section arm 11;

[0096] It should be noted that when the first arm 11 is in the groove 45, it is in an inclined state, and the incomplete gear 31 cannot cooperate with the first gear 23. When the cam 21 lifts the first arm 11, the first arm 11 returns to a horizontal state, so that the first gear 23 can cooperate with the incomplete gear 31.

[0097] It should also be noted that the first bevel gear set 20 in this embodiment includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the cam 21 and the first transmission rod 5 respectively. The second bevel gear set 32 ​​also includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed to the second transmission rod 30 and the third transmission rod 33 respectively.

[0098] A second motor 8 is fixed on the support seat 9, and the output shaft of the second motor 8 is coaxially fixed with a section arm 11. The function of the second motor 8 is to drive the section arm 11 to rotate through the second motor 8 to achieve the required action of the coating assembly.

[0099] The present invention also provides a multi-angle grinding method for processing a rotary joint workpiece, wherein the multi-angle grinding method for processing a rotary joint workpiece adopts the multi-angle grinding device for processing a rotary joint workpiece, and comprises the following steps:

[0100] Step 1: Install or disassemble the rotary joint 15 by controlling the opening and closing of the installation component through the disassembly component;

[0101] Step 2: The driving assembly drives the support seat 9, the first arm 11, the second arm 12 to rotate at the same angle, so as to drive the rotary joint 15 to follow the movement;

[0102] Step three, when the rotary joint 15 is on the rust removal assembly, the rotary joint 15 is subjected to rust removal treatment by the rust removal assembly, and when the rotary joint 15 is on the polishing belt 2, the rotary joint 15 is subjected to polishing treatment by the polishing assembly.

[0103] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
