DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1, reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a magnetic field composite ultrasonic engine blade repair spraying device, which can realize the repair spraying of the magnetic field composite ultrasonic engine blade, and includes a spraying mechanism 100 and a clamping mechanism 200.

[0027] Specifically, the spraying mechanism 100 includes a machine platform 101, a fixed plate 102 is fixedly installed on the top of the machine platform 101, and a spraying robot 103 for repairing and spraying the blades is installed at the center of the surface of the fixed plate 102. At the same time, a drying bin 104 for drying the blades after spraying is also installed on the outer edge of the surface of the fixed plate 102.

[0028] The clamping mechanism 200 can clamp the blade to be repaired so that the subsequent repair process can proceed smoothly.

[0029] Furthermore, a circulating track 102a is provided on the outer edge of the surface of the fixed disk 102, and a positioning groove 102b is provided on the circulating track 102a. The circulating track 102a is a circular connecting track, and the clamping mechanism 200 cooperates with the circulating track 102a, so that the blade can slide in the circulating track 102a through the clamping mechanism 200 to realize the switching of the repair station, that is, the blade is sprayed when facing the spraying robot 103. After the spraying is completed, it can be transferred to the drying chamber 104 for drying through further sliding of the clamping mechanism 200.

[0030] In summary, through the movable setting of the clamping mechanism 200, the workstation switching during the blade repair process can be quickly achieved, thereby improving the blade repair efficiency.

[0031] Example 2, reference Figure 1 to Figure 7 This is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a clamping mechanism 200 and a driving mechanism 300 of a magnetic field composite ultrasonic engine blade repair spraying device, which solves the problem of inconvenience in clamping and locking the blade.

[0032] Specifically, the clamping mechanism 200 includes a circulating member 201 movably disposed inside the circulating track 102a on the fixed disk 102, a gear ring 202 is coaxially fixedly disposed outside the circulating member 201, and a clamping member 203 is disposed on the surface of the circulating member 201.

[0033] The driving mechanism 300 includes a motor 301 mounted on the machine platform 101 . The output shaft of the motor 301 is connected to a driving bevel gear 302 via a coupling. The outer side of the driving bevel gear 302 is connected to a control member 303 .

[0034] Furthermore, the circulating part 201 includes a slide 201a, a stop block 201b is fixedly provided at the bottom of the slide 201a, and a sleeve 201c coaxially arranged with the slide 201a is fixedly provided at the bottom of the stop block 201b, and a support spring 201d is fixedly embedded inside the sleeve 201c, and a positioning column 201e is connected to the bottom of the support spring 201d, and the support spring 201d can shrink through its own deformation to realize the retraction of the positioning column 201e into the interior of the sleeve 201c.

[0035] The clamping member 203 includes a fixed plate 203a fixed to the surface of the slide 201a and a movable plate 203b movably arranged on the opposite side of the fixed plate 203a. The bottom of the movable plate 203b is embedded in the inside of the slide 201a, and it can slide on the surface of the slide 201a. A return spring 203c is arranged on the outer side of the bottom of the movable plate 203b, and the other end of the return spring 203c is abutted against the inner wall of the slide 201a. At the same time, locking teeth 203d are fixedly arranged on both sides of the movable plate 203b.

[0036] The control member 303 includes a control ring 303a rotatably arranged on the periphery of the fixed disk 102, a driven bevel gear ring 303b202 is fixedly arranged at the bottom of the control ring 303a, a clamping push plate 303c is fixedly arranged on the inner edge of the top of the control ring 303a, and a driving tooth 303d and a stop buckle 303e are also arranged in sequence on the inner side of the control ring 303a.

[0037] Preferably, the sleeve 201c and the circulating track 102a are slidably matched, so that the slide seat 201a can move smoothly in the circulating track 102a through the sleeve 201c, and the positioning column 201e is matched with the positioning groove 102b, and the positioning groove 102b is lower than the circulating track 102a, so that when the positioning column 201e is located inside the positioning groove 102b, the sleeve 201c is difficult to continue to slide along the circulating track 102a, and the positioning column 201e can be in the positioning groove 102b. It rotates inside. It should be noted that the connection between the circulating track 102a and the positioning groove 102b is set at a slope. Therefore, under the retractable setting of the positioning column 201e squeezing the support spring 201d, when the sliding sleeve 201c is subjected to external thrust, the positioning column 201e can be pushed by the reverse force of the slope surface between the circulating track 102a and the positioning groove 102b. Retract into the sliding sleeve 201c, thereby ensuring the subsequent smooth sliding of the sliding seat 201a along the circulating track 102a.

[0038] Furthermore, the active bevel gear 302 is meshed with the driven bevel gear ring 303b202, so that when the motor 301 drives the active bevel gear 302 to rotate, the control ring 303a can be driven to rotate synchronously through the meshing between the active bevel gear 302 and the driven bevel gear ring 303b202, thereby meeting the subsequent coordination and use requirements of the clamping push plate 303c, the driving tooth 303d and the anti-rotation buckle 303e.

[0039] The clamping push plate 303c is arranged in a fan shape, and the movable plate 203b is located on the rotation path of the clamping push plate 303c. Therefore, when the clamping push plate 303c passes the position of the clamping push plate 303c as the control ring 303a rotates, the movable plate 203b can be acted on by the inclined surface of the clamping push plate 303c to push the movable plate 203b to move toward the fixed plate 203a, thereby clamping the blade to be repaired.

[0040] A plurality of drive teeth 303d are arranged in an equiangular array along the inner edge of the control ring 303a, and the drive teeth 303d are meshed with the gear ring 202. The number of drive teeth 303d is consistent with the number of teeth on the outer edge of the gear ring 202, so that when the drive teeth 303d are meshed with the gear ring 202, the gear ring 202 can be guaranteed to rotate one circle from the start of meshing to the disengagement of meshing. Therefore, the gear ring 202 can be used to make the entire slide 201a rotate in the positioning groove 102b, so that the blade can rotate during the spray repair process, which is convenient for the spray robot 103 to spray and repair various directions of the blade surface. There is no need for the user to repeatedly load and unload the blade according to the different repair positions of the blade, reducing the limitations caused by the fixed position during the blade repair.

[0041] The stop block 201b is set in an arc shape coaxial with the control ring 303a, and the stop buckle 303e can be plugged into the stop block 201b, so that when the stop buckle 303e is matched with the stop block 201b as the control ring 303a rotates, while the stop buckle 303e pushes the slide 201a to continue sliding along the circular track 102a, the stop buckle 303e can limit the rotation of the slide 201a to ensure that the blades are in a posture that cooperates with the drying chamber 104, so that the drying inside the drying chamber 104 can be carried out smoothly.

[0042] When in use, the blade to be repaired is placed between the fixed plate 203a and the movable plate 203b, and then the motor 301 is started, and the motor 301 drives the active bevel gear 302 to rotate, and then the active bevel gear 302 and the driven bevel gear ring 303b202 are meshed and cooperated, and the control ring 303a is synchronously driven to rotate. As the control ring 303a rotates, the clamping push plate 303c first contacts the movable plate 203b, and gradually pushes the movable plate 203b to move toward the fixed plate 203a, so that the blade to be repaired is repaired. The spraying robot 103 is then started to repair the blade, and as the control ring 303a continues to rotate, the inner driving tooth 303d of the control ring 303a gradually meshes with the outer tooth ring 202 of the slide 201a, thereby driving the slide 201a to rotate, so that the blade can automatically adjust the spraying position to meet the spraying repair needs of different positions of the blade. After the blade rotates one circle and the spraying repair is completed, the stop buckle 303e rotates with the control ring 303a. The plug-in cooperation with the stop block 201b is completed, thereby locking the slide 201a to prevent the slide 201a from driving the blade to rotate again. At this time, as the control ring 303a rotates further, the stop buckle 303e cooperates with the stop block 201b, and the stop buckle 303e pushes the clamping mechanism 200 as a whole to move with the rotation of the control ring 303a. At this time, the positioning column 201e is between the thrust of the stop buckle 303e and the slope surface between the circulating track 102a and the positioning groove 102b. Under the cooperation of the reaction force, the extrusion support spring 201d completes the contraction into the sleeve 201c, so that the positioning column 201e disengages from the positioning groove 102b. At this time, the slide 201a can slide inside the circulating track 102a driven by the sleeve 201c, and with the rotation of the control ring 303a, the slide 201a drives the blades to be transferred to the drying chamber 104 for drying. After the drying is completed, the control ring 303a continues to rotate to make the blades rotate out, and the blades are removed to complete the repair of the blades.

[0043] In summary, through the cooperation between the clamping mechanism 200 and the driving mechanism 300, the degree of automation of the blade repair process is improved, the automatic clamping of the blade by the device, the automatic adjustment of its own position during the blade repair process and the automatic conversion of the repair station are realized, and the repair efficiency of the blade is improved.

[0044] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a clamping mechanism 200 and a driving mechanism 300 of a magnetic field composite ultrasonic engine blade repair spraying device, which solves the problem of inconvenience in locking and unlocking the clamping state of the clamping member 203. It includes a clamping mechanism 200 and a driving mechanism 300.

[0045] Specifically, the clamping mechanism 200 also includes a locking piece 204 arranged on the outside of the clamping piece 203, and two groups of locking pieces 204 are symmetrically arranged about the clamping piece 203. The locking piece 204 includes a rotating column 204a rotatably embedded in the sliding seat 201a, a locking plate 204b is arranged on the outside of the rotating column 204a, and a friction wheel 204c is coaxially fixed at the end of the rotating column 204a.

[0046] The driving mechanism 300 further includes a friction plate 304 fixedly disposed on the surface of the fixed disk 102 .

[0047] Furthermore, the locking plates 204b are arranged in a horizontal array along the axial direction of the rotating column 204a, and the locking plates 204b are deformable, and at the same time, the locking plates are inclined toward the fixed plate 203a, so that when the movable plate 203b clamps the blades, as the movable plate 203b moves toward the fixed plate 203a, the latch teeth 203d on both sides thereof pass through the locking plates 204b in turn, and after completing the clamping of the blades, they engage with the adjacent blades, so that the position of the movable plate 203b is locked through the abutment between the latch teeth 203d and the locking plates 204b, thereby preventing the movable plate 203b from loosening its clamping of the blades.

[0048] The top of the friction wheel 204c protrudes from the surface of the slide 201a, and the friction plate 304 is arranged at the same horizontal plane as the friction wheel 204c. The rotation path of the friction plate 304 coincides with the friction wheel 204c, and the friction wheel 204c and the friction plate 304 rotate relative to each other. Therefore, after the blade is sprayed, repaired and dried, as the control ring 303a continues to rotate, the slide 201a gradually slides to the friction plate 304 on the circulating track 102a, thereby the contact between the friction plate 304 and the friction wheel 204c can be The friction causes the rotating column 204a to rotate. At this time, the relative position of the locking piece 204b and the latch tooth 203d changes with the rotation of the rotating column 204a, thereby releasing the position restriction of the movable plate 203b. The movable plate 203b can then be reset under the action of the reset spring 203c to release the clamping of the blade. At the same time, as the friction plate 304 continues to extend, the friction wheel 204c can be reset again under the continued movement of the slide 201a, so as to facilitate the subsequent use of the movable plate 203b to limit the position again.

[0049] When in use, after the blades are repaired by spraying and dried, the control ring 303a rotates again. At this time, as the slide 201a gradually moves, the friction wheel 204c gradually moves to the position of the friction plate 304 and contacts it. At this time, with the help of the friction force between the friction wheel 204c and the friction plate 304, the rotating column 204a is rotated to dislocate the locking piece 204b, thereby releasing the restriction on the movable plate 203b. Then, the movable plate 203b is reset under the push of the reset spring 203c, releasing the clamping of the blade, so that the user can remove the blade, and then the control ring 303a continues to rotate to push the clamping The holding mechanism 200 returns to the positioning groove 102b to facilitate the repair of the next blade, and after the clamping mechanism 200 is reset, the control ring 303a reverses itself again, so that the clamping push plate 303c returns to the opposite side of the movement direction of the clamping mechanism 200, so that it can cooperate with the clamping mechanism 200 again in subsequent use. During the return process of the clamping push plate 303c, the movable plate 203b will be pushed for the second time to perform the clamping action. At this time, the subsequent blades can be repaired, that is, after the clamping push plate 303c returns, the above-mentioned repair process is continued to achieve cyclic repair of multiple blades.

[0050] In summary, through the cooperation between the locking piece 204 and the friction plate 304, a material unloading station is provided for the entire repair process. After the blade is sprayed and dried, the blade unloading operation can be realized as the control ring 303a and the slide seat 201a continue to move. That is, the device provides a three-station operation for blade repair. After loading, spraying, drying and unloading are automatically performed in sequence, which reduces the user's workload and greatly improves the blade repair speed.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
