Description

Technical Field

[0001] The invention relates to the technical field of workpiece cleaning devices, and in particular to a workpiece surface cleaning device before thermal barrier coating is applied. Background Art

[0002] Thermal barrier coating is a special coating that is mainly used to improve the heat resistance of materials in high temperature environments. Therefore, in order to improve the performance of workpieces in high temperature environments, thermal barrier coating can be coated on the surface of workpieces to extend the service life of workpieces in high temperature environments. Before thermal barrier coating, the workpiece needs to be cleaned of dust, impurities and oil on the surface using a cleaning device to ensure the stability of subsequent thermal barrier coating work.

[0003] In order to improve the adhesion of the thermal barrier coating on the workpiece, the workpiece needs to be surface polished and cleaned. However, the existing surface cleaning device has a relatively single function and a low degree of automation in the actual working process. It cannot automatically and integratedly complete the polishing, brushing and drying of the workpiece, and the work efficiency is low. Due to the different sizes of workpieces in different batches, the existing surface cleaning device cannot be adjusted according to the different batches of workpieces in the actual working process, and thus cannot conveniently and stably complete the batch clamping and positioning of the workpiece, thereby failing to ensure convenient and stable cleaning of batch workpieces. The practicability and applicability are poor. Therefore, it is necessary to provide a workpiece thermal barrier coating surface cleaning device before coating to meet the needs of users.

[0056] In this embodiment, the side end surface of the first limiting plate 14 is fitted with the side end surface of the second limiting plate 18, the side end surface of the second limiting plate 18 is in an arc shape, a groove is provided on the first limiting plate 14, the direction of the rotating rod 15 is the same as the direction of the groove on the first limiting plate 14, eight second levers 19 are provided, and the eight second levers 19 are distributed at equal angles on the driven shaft 17, a limiting groove 21 is provided on the top of the center column 703, and the bottom of the limiting block 20 is limitedly slidably connected in the limiting groove 21 The cross-sections of the limit block 20 and the limit groove 21 are both rectangular, and electromagnetic valves are installed on the drain pipe 22 and the water inlet pipe 10. Driven by the second servo motor 13, the first lever 16 and the second lever 19 can drive the driven shaft 17 to automatically and stably rotate intermittently, and each rotation is 45°, thereby driving the clamped and positioned workpieces to gradually move to the grinding, brushing and drying locations, thereby ensuring the convenience and efficiency of subsequent grinding, brushing and drying of the workpieces.

[0057] It should be noted that the present invention is a device for cleaning the surface of a workpiece before thermal barrier coating is applied. First, the staff can drive the second servo motor 13 on the first transfer frame 5. Under the driving action of the second servo motor 13, the first limit plate 14 and the rotating rod 15 on the output shaft can be driven to rotate simultaneously. Under the rotation action of the rotating rod 15, the second lever 19 can be shifted by the first lever 16. When the first lever 16 shifts the second lever 19, the groove on the first limit plate 14 rotates to align with the second limit plate 18. At this time, the first limit plate 14 will not limit the second limit plate 18. Therefore, when the first lever 16 shifts the second lever 19, it can drive the second limit plate 18 on the driven shaft 17 to rotate. Then, the first limit plate 14 continues to rotate and fits with the second limit plate 18 again. At this time, Under the fitting action of the first limiting plate 14 and the second limiting plate 18, the arc surface can be used to limit the second limiting plate 18 to prevent the second limiting plate 18 from shaking when it stops rotating. In this way, the intermittent movement of the first lever 16 and the second lever 19 can drive the driven shaft 17 to automatically and stably rotate intermittently, and each time it rotates 45°. At this time, the driven shaft 17 can drive the center column 703 to rotate synchronously and intermittently through the limiting block 20 and the limiting groove 21, and each time it rotates 45°. Under the intermittent rotation of the center column 703, the first clamping plates 716 on both sides of each protective frame 707 can be driven to move between the first circular gear 605 and the second circular gear 622, so as to prevent the first circular gear 605 and the second circular gear 622 from causing motion interference with the first clamping plate 716.

[0058] Then the staff can drive the hydraulic rods 2 on both sides of the bottom plate 1. Under the driving action of the hydraulic rods 2 on both sides, the protective shell 3 can be pushed to move upward. Under the upward movement of the protective shell 3, the limit block 20 at the bottom end of the driven shaft 17 can be driven to move out of the limit groove 21 through the first transfer frame 5. Then the protective shell 3 continues to move upward until the protective shell 3 does not block the central column 703. Then the two staff members can place the workpiece to be cleaned between the first clamping plates 716 on both sides of the same group of protective frames 707. At the same time, the staff can rotate the first threaded rod 70 at the bottom of the central column 703. 4. Under the rotation of the first threaded rod 704, the connecting plate 705 connected by the thread can drive the rack 706 to move upward stably. Under the upward movement of the rack 706, the third circular gear 710 inside the same group of protective frames 707 can be driven to mesh and rotate at the same time. Under the rotation of the third circular gear 710, the worm 709 can be driven to rotate, and then the worm wheels 711 meshed on both sides of the worm 709 can be driven to rotate toward the middle at the same time. At this time, under the rotation of the worm wheels 711 on both sides, the first traction rod 713 on the gear shaft 712 can drive the fixed rod 714 to move, and cooperate with the corresponding The second traction rod 715 can drive the first clamping plates 716 on both sides to move toward the middle at the same time, so that the workpiece can be clamped and positioned conveniently and stably. Before clamping and positioning, the staff can rotate the second threaded rod 721 on the first clamping plate 716. Under the threaded rotation of the second threaded rod 721, the guide block 723 can be pushed to move toward the outside of the storage groove 717 through the rotating plate 722. Under the movement of the guide block 723, the guide groove 720 can push the second clamping plate 719 on the second rotating shaft 718 to rotate outward. By adjusting the rotation angle of the second clamping plates 719 on both sides, The clamping range can be conveniently adjusted according to the shape and size of the workpiece, ensuring the convenience and stability of the subsequent clamping and positioning of the workpiece, thereby ensuring the stability of the subsequent grinding and brushing of the workpiece. When cleaning the workpieces of the same batch, only one adjustment is required. When another batch of workpieces needs to be cleaned, it can be adjusted again according to the size of the other batch of workpieces, which effectively improves the practicality and applicability of the device. Subsequently, the staff can use the other three sets of protection frames 707 through the same operation to clamp and position other workpieces, thereby conveniently completing the batch clamping and positioning of the workpieces.

[0059] After each workpiece is clamped and positioned, the staff can drive the hydraulic rods 2 on both sides of the base plate 1 again, and then drive the protective shell 3 to move downward and reset. At this time, the first transfer frame 5 can drive the limit block 20 to stably insert into the limit groove 21 at the top of the center column 703 through the driven shaft 17, so as to ensure the stability of the subsequent driving work of the center column 703; then the staff can drive the first servo motor 4 in the protective shell 3, and under the driving action of the first servo motor 4, the first transfer frame 5 can be driven to rotate stably through the output shaft, and under the continuous rotation of the first transfer frame 5, each first fixed plate 601 and each The second fixing plate 614 performs circular motion at the same time. Meanwhile, during the rotation of the first transfer frame 5, the second servo motor 13 is not driven, but the second servo motor 13 performs circular motion following the first transfer frame 5. At this time, the first limiting plate 14 on the output shaft of the second servo motor 13 also performs circular motion. Under the circular motion of the first limiting plate 14, the first limiting plate 14 can move the second limiting plate 18 to perform synchronous motion by utilizing the fit limit between the first limiting plate 14 and the second limiting plate 18, thereby driving the center column 703 to perform synchronous rotation through the limiting block 20 on the driven shaft 17.

[0060] Then the staff can drive the second servo motor 13. Similarly, the first lever 16 and the second lever 19 can be intermittently moved to drive the driven shaft 17 to automatically and stably rotate intermittently, and rotate 45° each time relative to the first transfer frame 5. At this time, the driven shaft 17 can drive the center column 703 to rotate intermittently synchronously through the limit block 20 and the limit groove 21, and rotate 45° each time. Under the intermittent rotation of the center column 703, the workpieces clamped and positioned at each protective frame 707 can be driven to gradually move to the flexible grinding plate 613, the second transfer frame 619 and the nozzle 809.

[0061] During the circular motion of each first fixed plate 601 and each second fixed plate 614, the first circular gear 605 on each first rotating shaft 604 can be driven to move in a circular motion on the internal gear 606 through the first supporting plate 603. Similarly, the second circular gear 622 on each second transfer frame 619 can be driven to move in a circular motion on the internal gear 606 through the guide tube 618 on the second supporting plate 616. At this time, under the meshing drive of the internal gear 606, each first circular gear 605 and each second circular gear 622 can automatically rotate during the circular motion. When the workpiece moves to the flexible grinding plate 613, the rotation of each first circular gear 605 can drive the corresponding flexible grinding plate 613 to rotate synchronously, so that the upper and lower surfaces of the clamped and positioned workpiece can be automatically and stably polished.

[0062] Similarly, the rotation of each second circular gear 622 can drive the second transfer frame 619 to rotate synchronously. During the rotation of the second transfer frame 619, the cleaning water can be transported to the third transfer frame 9 through the water inlet pipe 10, and then stably transported to the first transfer frame 5 through the connecting pipe 11. At this time, the cleaning water can be stably transported to the guide pipe 618 through the first guide groove 615 in the second fixed plate 614 and the second guide groove 617 in the second support plate 616, and sprayed out through each through hole 620 on the second transfer frame 619; the workpiece after grinding can be rotated to the nozzle 809 after the first 45° rotation, and then continue to rotate. After the second 45° rotation, it can move to When the second transfer frame 619 is in operation, the second transfer frame 619 is continuously rotated, and the flexible brushes 621 are combined to efficiently perform batch scrubbing on the workpieces after the grinding process, thereby effectively removing dust, impurities and oil stains on the surface of the workpieces, and the waste water after use can be discharged through the drain pipe 22; and during the rotation of the first transfer frame 5, since the third transfer frame 9 and the connecting pipe 11 are fixed, a second sealing plate 12 is designed, and the bearing connection of the second sealing plate 12 is utilized. When the first transfer frame 5 rotates, the second sealing plate 12 can be in a stationary state, so the connecting pipe 11 can stably transport the cleaning water to the first transfer frame 5 in the continuous rotation process, thereby ensuring the stability of the subsequent scrubbing work;

[0063] The workpiece after brushing is then intermittently rotated 45 degrees again and moved to the nozzle 809. During the operation of the device, the air inside the device can be sucked through the first air duct 807 under the driving action of the air pump 806, and then the air is transported to each nozzle 809 on the second air duct 808 through the processing frame 801 and sprayed out. This reciprocating process can conveniently complete the circulation of air inside the device, and during the air circulation process, the circulating air can be efficiently heated under the continuous heating action of each electric heating tube 802, so that the workpiece after grinding and brushing can be heated. The filter frame 805 can be used to filter the air during the air circulation process. After the device is finished working, the magnetic cover 803 can be used to absorb the air. The staff only needs to lift the magnetic cover 803 to drive the filter frame 805 to move out of the processing frame 801 through the connecting rod 804, so as to complete the disassembly of the filter frame 805, thereby ensuring the convenience of subsequent cleaning of the filter frame 805. The filter frame 805 can be installed by simply placing the filter frame 805 into the processing frame 801, thereby ensuring the stability of the subsequent working state of the filter frame 805.

[0064] After all the workpieces have been polished, scrubbed and dried, the staff can drive the hydraulic rods 2 on both sides of the bottom plate 1 again. Under the driving action of the hydraulic rods 2 on both sides, the protective shell 3 can be pushed to move upward until the protective shell 3 does not block the central column 703. Then, the two staff members can reversely rotate the first threaded rod 704 at the bottom of the central column 703. Under the reverse rotation of the first threaded rod 704, the threaded connecting plate 705 can drive the rack 706 to move downward and reset. Under the downward movement of the rack 706, the worm 709 can be driven to rotate in the opposite direction through the third circular gear 710. At this time, under the reverse rotation of the worm wheels 711 on both sides, the first traction rod 713 on the gear shaft 712 can drive the fixed rod 714 to move, and cooperate with the corresponding second traction rod 715 to drive the first clamping plates 716 on both sides to move to both sides at the same time, thereby driving the first clamping plates 716 on both sides to move away from the workpiece, thereby conveniently completing the workpiece unloading work;

[0065] After the device is finished working, the staff can pull the clamping rod 609 on the connecting plate 607 to the side until the clamping rod 609 moves out of the clamping groove 612 on the positioning rod 611, and then the flexible grinding plate 613 can drive the positioning rod 611 to move out of the positioning groove 610 on the first circular gear 605, completing the disassembly of the flexible grinding plate 613. Then the staff can take a new flexible grinding plate 613 and insert the positioning rod 611 on the flexible grinding plate 613 into the positioning groove 610 on the first circular gear 605. During the insertion process of the positioning rod 611, it can contact the inclined surface of the end of the clamping rod 609 and push the clamping rod 609 to move to the side until the clamping groove 612 on the positioning rod 611 moves to the clamping rod 609. At this time, the clamping rod 609 can automatically engage with the clamping groove 612 on the positioning rod 611 under the elastic action of the reset spring 608, so that the clamping installation of the flexible grinding plate 613 can be completed conveniently, thereby improving the service life of the cleaning device.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
