Description

Technical Field

[0001] The invention relates to the technical field of thermal spraying, in particular to a thermal spraying fixture with ultrasonic vibration. Background Art

[0002] Thermal spraying technology is a method of using a heat source to heat the spraying material to a molten or semi-molten state, and then spraying it onto the pre-treated metal substrate surface at a certain speed to form a coating with specific functions. Generally, it can prepare anti-corrosion, wear-resistant, friction-reducing, high-temperature resistant, and anti-oxidation coatings, and is widely used in the industrial field. However, the existing fixtures used for thermal spraying have relatively single functions and are generally only suitable for spraying rotating parts, and are not competent for flat parts. In addition, there are many pores in the spraying process, which affect the final performance of the coating. Based on the above considerations, an ultrasonic vibration device is introduced to make full use of the characteristics of ultrasonic vibration. During the deposition process of spray powder, the grains can be refined, the pores of the coating can be reduced, and the bonding strength between the coating and the substrate can be improved, thereby ultimately improving the overall performance of the coating.

[0003] After searching, it was found that the prior art publication number is CN109321862B, which discloses a thermal spraying fixture with ultrasonic vibration, which is connected to a front and rear moving plate by sliding on a bottom plate; a gear rack transmission mechanism is connected between the front and rear moving plate and the bottom plate; a claw plate seat and a left and right moving plate arranged laterally opposite to each other are provided on the front and rear moving plates; a horizontal screw guide rail motion pair mechanism is connected between the left and right moving plates and the front and rear moving plates; a claw plate assembly is rotatably installed in the claw plate seat and the left and right moving plates; an ultrasonic vibration plate is installed in the claw plate assembly, and one side of one claw plate assembly is connected to a gear transmission mechanism, so that it is suitable for substrates of various specifications, and the spraying angle can be changed according to needs; at the same time, the substrate inclination angle can be adjusted in time according to the spraying needs, providing greater flexibility for the spraying process;

[0004] However, when the above-mentioned device is clamping the workpiece, a potential difference is generated when the workpiece contacts the contact surface of the claw disk assembly, resulting in electrical corrosion, that is, electrochemical corrosion. This corrosion will accelerate the material loss of the contact surface between the workpiece and the claw disk assembly, resulting in increased surface roughness, and even the formation of pits or cracks, which seriously affects the accuracy of the workpiece and the service life of the claw disk assembly. In addition, if the materials of the workpiece and the fixture are different, such as stainless steel and carbon steel, the potential difference may also affect the spraying quality. During the spraying process, the potential difference will cause defects in the spraying area, such as pores, cracks, etc., thereby reducing the effect and reliability of the spraying; in addition, the potential difference will cause uneven distribution of paint particles in the electric field. In areas with larger potential differences, paint particles may be subject to stronger electrostatic attraction, thereby depositing more on the surface of the workpiece to form a thicker coating, while in areas with smaller potential differences, the amount of paint particles deposited is relatively small, resulting in a thinner coating. This uneven deposition phenomenon will seriously affect the appearance and performance of the coating, and excessively aggregated paint particles may cause bulges or granularity on the coating surface, while uneven dispersion may cause spots or color differences on the coating surface;

[0005] Therefore, based on the above search and in combination with the prior art, a thermal spraying fixture with ultrasonic vibration is proposed to solve the above problems. Summary of the invention

[0029] 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.

[0030] In a typical implementation of this application, please refer to Figures 1 to 9As shown, a thermal spraying fixture with ultrasonic vibration includes two legs 1, a workbench 2 is fixedly installed on the top surface of the two legs 1, a distribution box 3 is fixedly installed on the front side wall of the workbench 2, the distribution box 3 can supply power to the equipment, a controller 4 is fixedly installed on the top surface of the workbench 2, the controller 4 can control various components on the equipment, a vibration guide rail 5 is fixedly installed at the center of the top surface of the workbench 2, limit blocks 6 are fixedly installed at both ends of the vibration guide rail 5, and a movable plate 7 is slidably connected to the vibration guide rail 5;

[0031] Connecting blocks 42 are fixedly installed at both ends of the bottom surface of the workbench 2, connecting rods 43 are fixedly installed on the side walls of the two connecting blocks 42, a connecting plate 44 is fixedly installed between the two connecting rods 43, a plurality of spray heads 45 are fixedly installed on the bottom surface of the connecting plate 44, a spray liquid storage box 46 is fixedly installed on the rear side wall of the workbench 2, and a connecting pipe 47 is arranged between the spray liquid storage box 46 and the connecting plate 44.

[0032] The clamping mechanism is arranged on the movable plate 7, and the clamping mechanism comprises:

[0033] Two semi-arc plates 8, the two semi-arc plates 8 are slidably connected to the top surface of the moving plate 7, the top surface of the moving plate 7 is provided with a slide groove 9, the inner wall of the slide groove 9 is rotatably connected with a threaded rod 10, the threaded rod 10 is provided with two sections of threads with opposite rotation directions, the two sections of threads of the threaded rod 10 with opposite rotation directions are connected with sliders 11, the top surfaces of the two sliders 11 are respectively fixedly connected to the bottom surfaces of the two semi-arc plates 8, and the left side wall of the moving plate 7 is fixedly installed with a driving motor 12, and the output shaft of the driving motor 12 is connected to the side wall of the threaded rod 10;

[0034] When clamping, firstly, the controller 4 is used to control the start of the driving motor 12, so that the threaded rod 10 connected to the output shaft of the driving motor 12 rotates, so that the slider 11 on the threaded rod 10 moves in the slide groove 9 and approaches each other, so that the semi-arc plate 8 fixedly connected to the slider 11 also moves synchronously, so that it approaches to clamp the workpiece between the two semi-arc plates 8, so as to facilitate spraying;

[0035] The above process is the basic process of thermal spray fixture clamping at present.

[0036] However, in the process of clamping the workpiece, a potential difference is generated when the workpiece contacts the contact surface of the semi-arc plate 8, resulting in electrical corrosion, i.e., electrochemical corrosion. This corrosion accelerates the material loss of the contact surface between the workpiece and the semi-arc plate 8, resulting in increased surface roughness, and even the formation of pits or cracks, which seriously affects the accuracy of the workpiece and the service life of the semi-arc plate 8. In addition, if the materials of the workpiece and the fixture are different, such as stainless steel and carbon steel, the potential difference may also affect the spraying quality. During the spraying process, the potential difference may cause defects in the spraying area, such as pores and cracks, thereby reducing the effect and reliability of the spraying.

[0037] In addition, the potential difference will cause uneven distribution of paint particles in the electric field. In areas with larger potential differences, paint particles may be subject to stronger electrostatic attraction, thereby depositing more on the workpiece surface to form a thicker coating. In areas with smaller potential differences, the amount of paint particles deposited is relatively small, resulting in a thinner coating. This uneven deposition phenomenon will seriously affect the appearance and performance of the coating, and excessive aggregation of paint particles may cause bumps or granularity on the coating surface, while uneven dispersion may cause spots or color differences on the coating surface.

[0038] Therefore, based on the above problems, we first design an insulating mechanism, which is arranged on the semi-arc plate 8 and is used to prevent the potential difference between the workpiece and the semi-arc plate 8; the insulating mechanism includes: two insulating liquid storage boxes 13, the two insulating liquid storage boxes 13 are respectively rotatably connected to the adjacent surfaces of the two semi-arc plates 8, and the adjacent surfaces of the two insulating liquid storage boxes 13 are provided with mounting grooves 14, and the interiors of the two mounting grooves 14 are fixedly installed with trapezoidal blocks 15, the two trapezoidal blocks 15 are symmetrically arranged and rotated ninety degrees to be installed in the mounting grooves 14, and the interiors of the two trapezoidal blocks 15 are provided with inner cavities 16, and the two insulating An ultrasonic vibrator 17 is fixedly installed on the top surface of the liquid storage box 13. The ultrasonic vibrator 17 can generate vibration during the clamping process of the workpiece, so that the sprayed paint is more uniform. When the ultrasonic vibrator 17 is working, it will cooperate with the vibration guide rail 5 to make the semi-arc plate 8 move evenly on the vibration guide rail 5, which can drive the workpiece to gradually pass under the nozzle 45 to spray the workpiece. The vibrating end of the ultrasonic vibrator 17 extends to the interior of the insulating liquid storage box 13. The insulating mechanism also includes two groups of fixed components and sealing components, and the two groups of fixed components and sealing components are respectively arranged in two trapezoidal blocks 15.

[0039] As a preferred implementation in this embodiment, please refer to Figure 5 , Figure 7 and Figure 8 As shown, the fixing assembly includes: two electric push rods 18, the two electric push rods 18 are fixedly mounted on the two inner walls of the inner cavity 16 respectively, the two electric push rods 18 are symmetrically arranged, and the output ends of the two electric push rods 18 are fixedly mounted with clamping rings 19.

[0040] As a preferred implementation in this embodiment, please refer to Figures 5 to 8As shown, the sealing assembly includes: a fixed plate 21, which is fixedly mounted on the top surface inside the trapezoidal block 15, a liquid leakage port 20 is provided on the top surface of the trapezoidal block 15, a sliding groove 22 is provided on the top surface of the fixed plate 21, a limit rod 23 is fixedly mounted on the inner wall of the sliding groove 22, two sliding blocks 24 are sleeved on the outer surface of the limit rod 23, both sliding blocks 24 slide in the sliding groove 22, springs 25 are provided on the side walls of the two sliding blocks 24, pulleys 26 are provided at both ends of the bottom surface of the fixed plate 21, ropes 27 are provided on the side walls of the two sliding blocks 24, one end of the rope 27 is connected to the side wall of the sliding block 24, and the other end is connected to the side wall of the clamping ring 19 through the pulley 26, and sealing strips 28 are fixedly mounted on the bottom surfaces of the two sliding blocks 24.

[0041] Through the above-mentioned features, the potential difference between the workpiece and the fixture can be avoided. Specifically, the two semi-arc plates 8 are adjusted to the appropriate position, and then the two ends of the workpiece are placed in the two trapezoidal blocks 15 respectively. Then the staff turns on the electric push rod 18 through the controller 4, so that the clamping ring 19 connected to the output shaft of the electric push rod 18 clamps the two ends of the workpiece. During the clamping process, the two clamping rings 19 are close to each other, and the two sliding blocks 24 are separated from each other by the pulling force of the rope 27. During this process, the two sliding blocks 24 will squeeze and deform the spring 25 on one side. At the moment when the sliding blocks 24 are separated from each other, the insulating liquid in the insulating liquid storage box 13 will flow into both sides of the workpiece through the leakage port 20 and accumulate in the inner cavity 16. After the workpiece is sprayed, the staff only needs to turn on the electric push rod 18 through the controller 4 to separate the two clamping rings 19 from each other. At this time, the two sliding blocks 24 will be closed to each other due to the rebound force of the spring 25, and the sealing strips 28 under the two sliding blocks 24 will also be close to each other to prevent the leakage port 20 from penetrating the insulating liquid.

[0042] Based on the above problems, we also designed a purification component, which is arranged on the movable plate 7 and is used to purify and filter the insulation so that it can be used for a second time. The purification component includes: a collection box 29, which is fixedly mounted on the front side wall of the movable plate 7, and a filter box 30 is fixedly mounted on the top surface of the collection box 29. The interior of the filter box 30 is slidably connected with an activated carbon plate 32, a silica purification plate 33, a PVC purification plate 34 and a blocking net 35 from bottom to top in sequence, and a cover plate 36 is slidably connected to the inner wall of the filter box 30. A card slot 31 is provided at both ends of the inner wall of the filter box 30, and a card block 37 is fixedly mounted at both ends of the cover plate 36. The card block 37 is engaged with the card slot 31. The purification component also includes a transmission component.

[0043] As a preferred implementation in this embodiment, please refer to Figure 4 and Fig. 9As shown, the transmission component includes: two connecting pipes 38, the two connecting pipes 38 are respectively arranged on the two trapezoidal blocks 15, one end of the connecting pipe 38 is connected to the interior of the trapezoidal block 15, and the other end passes through the top surface of the cover plate 36 and extends to the interior of the filter box 30 and is located above the blocking net 35. The top surface of the collecting box 29 is located on one side of the filter box 30 and a water pump 39 is fixedly installed thereon, a water suction pipe 40 is arranged on one side of the water pump 39, and a three-way pipe 41 is arranged on the other side of the filter box 30, one end of the three-way pipe 41 is connected to the side wall of the water pump 39, and the other two ends are respectively connected to the side walls of the two insulating liquid storage boxes 13.

[0044] As a preferred implementation in this embodiment, please refer to Figure 2 to Figure 6 As shown, a second drive motor 48 is fixedly mounted on the side wall of one of the semi-arc plates 8 , and the output shaft of the second drive motor 48 is connected to the side wall of one of the insulating liquid storage boxes 13 . Observation chambers 49 are provided on both side walls of the two insulating liquid storage boxes 13 .

[0045] Through the above-mentioned features, the insulating liquid accumulated inside the trapezoidal block 15 can be filtered and then returned to the insulating liquid storage box 13 to reduce the consumption of the insulating liquid. Specifically, after the insulating liquid accumulated in the two trapezoidal blocks 15 reaches the specified position, it will flow into the filter box 30 through the two connecting pipes 38 respectively, and then flow into the collection box 29 for collection after being filtered through the blocking net 35, the PVC purification board 34, the silica purification board 33 and the activated carbon board 32 in turn. Then, the water pump 39 is turned on to allow the suction pipe 40 to extract the insulating liquid inside the collection box 29, and then flow into the insulating liquid storage box 13 through the three-way pipe 41. If the upper part of the workpiece is sprayed and it is necessary to spray the lower part, the staff only needs to pass The two insulating liquid storage boxes 13 can be rotated synchronously by turning on the driving motor 2 48 through the controller 4, and the observation chamber 49 is used to observe the usage of the insulating liquid in the two insulating liquid storage boxes 13, so that the staff can add insulating liquid in time. If it is necessary to clean or replace the blocking net 35, PVC purification board 34, silica rock purification board 33 and activated carbon board 32, the staff only needs to pull the cover plate 36 out of the card slot 31 through the handle above the cover plate 36 to open the filter box 30, and clean or replace the blocking net 35, PVC purification board 34, silica rock purification board 33 and activated carbon board 32 inside the filter box 30. If there is too little insulating liquid in the two insulating liquid storage boxes 13, insulating liquid can also be directly added in this step.

[0046] Working principle:

[0047] When in use, first start the driving motor 12 through the controller 4 to rotate the threaded rod 10. This action causes the sliders 11 on the two sections of the thread that rotate in opposite directions to the threaded rod 10 to move in the slide groove 9 and approach each other, thereby pushing the semi-arc plate 8 fixedly connected to the slider 11 to move synchronously, thereby clamping the workpiece placed between the two semi-arc plates 8 for spraying operations. During the spraying process, the ultrasonic vibrator 17 generates vibrations, and this vibration is used in conjunction with the vibration guide rail 5, so that the semi-arc plate 8 and the workpiece clamped therein can move evenly on the vibration guide rail 5. This movement helps the workpiece to gradually pass under the nozzle 45 to ensure the uniformity of the spraying. In addition, the vibration generated by the ultrasonic vibrator 17 also helps to improve the uniform distribution of the coating and reduce the occurrence of spraying defects such as pores and cracks, thereby improving the effect and reliability of the spraying. In order to solve the problem of potential difference that may be generated when the workpiece contacts the semi-arc plate 8, an insulating mechanism is designed for this device. The core of the insulating mechanism is two insulating liquid storage boxes 13. They The trapezoidal blocks 15 in the insulating liquid storage box 13 are respectively connected to the adjacent surfaces of the two semi-arc plates 8 for rotation. The insulating liquid is applied to the surface of the workpiece through the leakage port 20, which effectively prevents the generation of potential difference, thereby avoiding electrochemical corrosion and spraying quality problems. In addition, the equipment is also equipped with a purification component, which includes a collection box 29, a filter box 30 and a series of filter materials such as an activated carbon plate 32, a silica purification plate 33, a PVC purification plate 34 and a barrier net 35, which are used to purify and filter the used insulating liquid to achieve secondary utilization of the insulating liquid and reduce consumption. Through transmission parts such as a connecting pipe 38, a water pump 39 and a three-way pipe 41, the insulating liquid can be recycled during the spraying process, reducing resource waste. When one side of the workpiece is sprayed, the driving motor 2 48 can be operated by the controller 4 to rotate the insulating liquid storage box 13 so that the other side of the workpiece can be sprayed. The observation bin 49 allows the staff to monitor the remaining amount of the insulating liquid to ensure the continuity and efficiency of the spraying process.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
