Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature brazing parts, and in particular to high-temperature brazing parts finishing equipment used in high-temperature continuous brazing furnace processing. Background Art

[0002] A brazing furnace is a device used for brazing and bright heat treatment of metals. It is suitable for mass-produced small and medium-sized stainless steel parts, such as bright quenching and tempering of martensitic stainless steel and bright annealing of austenitic stainless steel. Brazing furnaces are used to effectively connect the components of aluminum heat exchangers, utilizing the lower melting point of the brazing alloy. The brazing material is typically placed near or within the weld surface of the connection. Aluminum brazing flux is applied between the component and the weld surface, as well as on the surface. The components are heated under a protective inert gas atmosphere to a temperature where the brazing alloy melts without melting the component metal.

[0003] In the prior art, a Chinese patent document with publication number CN110355638B proposes an aluminum alloy die-casting finishing machine and method thereof. By adopting a series of mechanical structures, the three-end shaft holes of the high-temperature brazing T-shaped tee cylindrical structure aluminum alloy die-casting are simultaneously finished, thereby solving the problem that the finishing of the workpiece of this structure requires multi-angle and multiple processing. In actual use, although this type of processing machinery effectively improves the grinding and polishing efficiency of the T-shaped tube, since the grinding or polishing mechanism adopted is the same as the traditional one, after the high-temperature brazing T-shaped tube is ground and polished, its surface will still have fine grinding scratches due to factors such as grinding fluid, which in turn affects the surface processing effect of the high-temperature brazing T-shaped tube, affects the feel and appearance of use, and cannot achieve true finishing.

[0041] like Figure 1-8As shown, a high-temperature continuous brazing furnace processing high-temperature brazing parts finishing equipment includes a machine tool bed 1, a grinding mechanism 2 for grinding and polishing a T-shaped tube 3, and a horizontal slide 4 for placing multiple T-shaped tubes 3, multiple horizontal slides 4 are each equipped with a support assembly for supporting the T-shaped tube 3 at a corresponding position, the support assembly includes multiple limiting air bags 10 respectively sleeved in the corresponding T-shaped tube 3, and support columns 6 installed in the multiple T-shaped tubes 3 and respectively connected to the corresponding limiting air bags 10, multiple A connecting assembly for adjusting the spacing between adjacent horizontal slides 4 is also provided between the horizontal slides 4. A liftable operating box 5 is fixedly installed on the top of the multiple horizontal slides 4. A detection assembly for detecting whether there are scratches on the outer walls of the multiple T-shaped tubes 3 is provided in the operating box 5. The detection assembly includes a camera 25 that can rotate to shoot the surface of the T-shaped tube 3. A nozzle 26 for corroding scratches on the surface of the T-shaped tube 3 is also installed on the detection assembly. The nozzle 26 is used to spray chemical reagents. When the T-shaped tube 3 of the high-temperature brazing part is finely processed, the polishing mechanism 2 is used to polish the T-shaped tube 3. The T-shaped tube 3 is ground and polished, and the ground and polished T-shaped tube 3 is inserted into the support column 6 on the corresponding horizontal slide 4, so that the detection component can detect scratches on the outer wall of the ground and polished T-shaped tube 3, avoid accidental deflection during the detection process, achieve stable detection, and improve the accuracy of detection. The camera 25 on the detection component moves and rotates to detect whether there are small scratches on the outer wall of the T-shaped tube 3. The chemical reagent used to corrode the surface of the high-temperature brazing T-shaped tube 3 is sprayed to the corresponding position through the spray head 26 (the chemical reagent is an acidic or alkaline solution that can react with both aluminum and aluminum oxide films. It is a prior art and will not be described here). Since the scratches have sharp edges, the corrosion rate is fast, so that the small scratches can be completely eliminated after chemical polishing, thereby improving the surface gloss of the T-shaped tube 3 and achieving true finishing of the high-temperature brazing T-shaped tube 3. In addition, by providing a connecting component and a liftable support column 6, it can be adapted to high-temperature brazing T-shaped tubes 3 of different sizes, further improving the practicality of the entire finishing device.

[0042] As a preferred implementation in this embodiment, multiple horizontal slides 4 are provided with threaded holes, multiple support columns 6 are fixedly sleeved with threaded sleeves 7, and multiple threaded sleeves 7 are respectively threadedly sleeved in the corresponding threaded holes, and the top ends of multiple support columns 6 are respectively sleeved in the corresponding T-shaped tubes 3, multiple support columns 6 are provided with connecting cavities 8, and the top ends of multiple connecting cavities 8 are fixedly connected with two limiting airbags 10 with the same height, the two limiting airbags 10 in relative positions are respectively located in the two ends of the same T-shaped tube 3, and the top ends of multiple support columns 6 are provided with two receiving grooves 9 that are connected to the corresponding connecting cavities 8, and multiple limiting airbags 10 are respectively located in the corresponding receiving grooves 9, a groove is provided on the machine tool bed 1, the bottom ends of multiple support columns 6 extend into the groove, and the bottom ends of multiple support columns 6 are provided with a The air intake valve 11 controls whether the corresponding connecting cavity 8 is connected or not. Before performing surface inspection on the polished high-temperature brazed T-tube 3, multiple T-tubes 3 of the same batch are respectively inserted into the corresponding support column 6, and then multiple air intake valves 11 are opened, and gas is injected into the multiple connecting cavities 8 through an external air pump, so that the two limiting airbags 10 at the corresponding positions are expanded and clamped on the two ends of the T-tube 3 at the same height to limit the T-tube 3, achieve subsequent stable detection, and accurately detect scratches on the outer wall of the T-tube 3, thereby improving the detection accuracy. In addition, through the limiting method of the expansion of the limiting airbag 10, the limiting operation can be completed for T-tubes 3 of different sizes. At the same time, by spirally rotating the threaded sleeve 7, the height of the support column 6 is adjusted, and then it can be adapted to the use of T-tubes 3 of different lengths, thereby improving the practicality of the entire lathe.

[0043] As a preferred implementation in this embodiment, the connecting assembly includes multiple double-headed screws 13 respectively located between adjacent horizontal slides 4, and multiple horizontal slides 4 are provided with connecting grooves 12 on both sides. The two ends of the multiple double-headed screws 13 are respectively threadedly sleeved in the corresponding connecting grooves 12. The rotation of the double-headed screws 13 is used to drive the horizontal slides 4 on the corresponding sides to move closer or farther away from each other. The middle outer walls of the multiple double-headed screws 13 are fixedly sleeved with rotating sleeves 14, and the multiple rotating sleeves 14 are fixedly connected with multiple evenly distributed rotating rods. When the lengths of the multiple T-shaped tubes 3 are different, by rotating the rotating rods at the corresponding positions, the rotating sleeves 14 drive the corresponding double-headed screws 13 to rotate synchronously, so that the two adjacent horizontal slides 4 at the corresponding positions are moved away from or closer to each other, and adapted to the length of the T-shaped tube 3 at the corresponding position, thereby realizing unified and centralized detection of T-shaped tubes 3 of different sizes and beautifying the outer tube wall, thereby improving the finishing efficiency of the T-shaped tube 3.

[0044] As a preferred embodiment of this embodiment, the detection component includes a horizontal electric slider 16 for driving the camera 25 to move in the horizontal direction. Two horizontal linear slides 15 at the same height are fixedly installed on the inner wall of the operation box 5. The two horizontal electric sliders 16 are respectively slidably mounted on the horizontal linear slides 15 on the corresponding sides. The detection component also includes an incomplete arc slide 17 fixedly mounted on the two horizontal electric sliders 16 and coaxially arranged with the operation box 5. The bottom end of the incomplete arc slide 17 is provided with a defective groove adapted to multiple T-shaped tubes 3. The incomplete arc slide rail 17 is slidably sleeved with a first arc electric slider 18, and the first arc electric slider 18 is fixedly connected to a semicircular arc slide rail 19 coaxially arranged with the incomplete arc slide rail 17. The semicircular arc slide rail 19 is slidably sleeved with a second arc electric slider 21, and the camera 25 and the nozzle 26 are indirectly connected to the second arc electric slider 21. The semicircular arc slide rail 19 is also fixedly clamped with two connecting blocks 20 located on both sides of the first arc electric slider 18, and the two connecting blocks 20 are both slidably sleeved on the incomplete arc slide rail 17.A mounting plate 22 is fixedly mounted on the second arc-shaped electric slider 21, and an electric telescopic rod 23 is fixedly sleeved on one end of the mounting plate 22. A spherical seat 24 is fixedly mounted on the telescopic end of the electric telescopic rod 23. A camera 25 is sleeved in the spherical seat 24 and corresponds to the position of the T-shaped tube 3. A corrosion tube is fixedly sleeved on the other end of the mounting plate 22. One end of the corrosion tube is connected to the external chemical reagent supply end and is installed with a second valve 27. A nozzle 26 is fixedly mounted on the other end of the corrosion tube and is connected to the corrosion tube. A controller 30 electrically connected to the camera 25 and the second valve 27 is also fixedly mounted on the outer wall of the operating box 5. The T-shaped tubes 3 of multiple high-temperature brazing parts are respectively fixed on the corresponding support columns 6. After it is put up, the horizontal electric sliders 16 on both sides are controlled to operate synchronously. Under the guidance of the horizontal linear slide 15, the camera 25 is moved in the horizontal direction through the connection between the incomplete arc slide 17 and the semi-circular arc slide 19. At the same time, the operation of the first arc electric slider 18 drives the entire semi-circular arc slide 19 to rotate, thereby indirectly driving the camera 25 to rotate, and cooperating with the operation of the second arc electric slider 21 to drive the camera 25 to further move in a circular motion, screwing in the outer wall of the two ends at the same height on the T-shaped tube 3 and identifying scratches, so as to make up for the gap on the incomplete arc slide 17 to compensate for the recognition blind spot of the T-shaped tube 3. At the same time, when the semi-circular arc slide When the rail 19 moves to the joint position on the T-tube 3, the first arc-shaped electric slider 18 operates and drives the semi-circular arc slide rail 19 to rotate to one side of the T-tube 3 to avoid cross contact between the semi-circular arc slide rail 19 and the T-tube 3, and drives the camera 25 to rotate and shoot the outer wall of the lower end of the T-tube 3 through the spherical seat 24 according to the rotation principle of the spherical camera, thereby realizing the recognition of scratches on the outer wall of the high-temperature brazing part T-tube 3. It should be noted here that the camera 25 sends the shot video to the central processing unit (which is the existing technology). The central processing unit includes a video processing module, a defect model image library, a comparison processing module, a judgment module, and a signal sending module. For example, the video of the video processing module is divided into multiple frames. The framed photos are poured into the defect model image library. The comparison processing module compares the framed photos with the defect image data in the defect model library. The judgment module makes a judgment. When the high-temperature brazing part is photographed and there are defects such as scratches, the signal sending module sends a signal to the controller 30. The controller 30 receives the signal and instructs the second valve 27 to control the second valve 27 to open and spray the chemical reagent on the corresponding position on the T-shaped tube 3 through the nozzle 26. Since the scratches have sharp edges and the corrosion rate is fast, the small scratches can be completely eliminated after chemical polishing, thereby improving the surface gloss of the T-shaped tube 3 and realizing the true meaning of the finishing treatment of the high-temperature brazing part T-shaped tube 3.

[0045] As a preferred implementation in this embodiment, four cylinders 28 are fixedly installed on the top of the machine tool bed 1, which are respectively located on both sides of the operation box 5. The telescopic ends of the cylinders 28 are fixedly connected to arc-shaped support plates 29 that fit the outer wall of the operation box 5. By arranging the cylinders 28, the cylindrical operation box 5 can be kept coaxial with the two ends of the T-tubes 3 of different sizes at the same height, thereby achieving precise detection. The operation box 5 is also provided with an observation window 31 that is compatible with the sum of the lengths of multiple T-tubes 3. The observation window 31 is made of transparent glass. By opening the observation window 31, the operator can intuitively observe the operating status inside the operation box 5.

[0046] like Figure 8-12 and Figure 17 As shown, as a preferred embodiment of this embodiment, a loading mechanism 32 for driving the T-shaped tube 3 to load materials and a unloading mechanism 33 for driving the T-shaped tube 3 to discharge materials are respectively provided on both sides of the machine tool bed 1;

[0047] The horizontal slide 4 is provided with a rotating mechanism 34 for driving the T-shaped tube 3 to rotate to cooperate with the inspection and processing work, and an auxiliary mechanism 35 provided outside the nozzle 26 and used to assist the nozzle 26 in concentrated spraying and waste collection;

[0048] The feeding mechanism 32 includes a first mounting frame 38 connected to the output end of the electric push rod 37 through a telescopic member 36, two sets of second mounting frames 39 connected to the two ends of the first mounting frame 38, a push plate 40 connected to the telescopic member 36, multiple sets of identification components 41 arranged on one side of the first mounting frame 38 and the second mounting frame 39 and used to identify the dimensions of the two ends of the T-shaped tube 3, and two sets of adjustment components 42 arranged on both sides of the first mounting frame 38 and used to cooperate with the identification components 41 to drive the horizontal slide 4 to adjust the spacing;

[0049] The identification assembly 41 includes a limiting plate 44 symmetrically connected to the first mounting frame 38 and the second mounting frame 39 via a first spring 43, a first receiving plate 45 and a second receiving plate 46 respectively connected to the first mounting frame 38 and the second mounting frame 39 and used to receive the T-shaped tube 3, a guide plate 47 connected to the limiting plate 44, and a limiting member 48 connected to the limiting plate 44 and used to fix the position of the limiting plate 44;

[0050] The limiting member 48 includes a mounting block 49 connected to the limiting plate 44, a plurality of mounting holes 50 formed on the mounting block 49, and a clamping block 52 connected to the inside of the mounting hole 50 via a torsion spring 51;

[0051] The adjustment assembly 42 includes two sets of first racks 53 connected to both sides of the first mounting frame 38, a first gear 55 connected to the first mounting frame 38 via a rotating shaft 54 ​​and cooperating with the first racks 53 for transmission, a driving rack 56 connected to the limiting plate 44 and cooperating with the first gear 55 for transmission, a second rack 57 connected to the bottom of the first rack 53, a second gear 58 connected to the double-headed screw and cooperating with the second rack 57 for transmission, a limiting rod 59 connected to the second receiving plate 46, and a limiting slot 60 provided on the horizontal slide 4 for cooperating with the limiting rod 59 to drive the second mounting plate to move;

[0052] The unloading mechanism 33 includes a moving rod 63 driven by a sprocket chain transmission member and moving in the circular groove plate 62, a tube unloading rack 64 connected to the moving rod 63 and used to remove the T-shaped tube 3, and a blocking rod 66 connected to the circular groove plate 62 and cooperating with the tube unloading rack 64 to place the T-shaped tube 3 into the release agent box 65.

[0053] like Figure 13-16 As shown, in this embodiment, the degree of automation of the device is improved by providing a loading mechanism 32 and a discharging mechanism 33. At the same time, due to the inconsistent sizes of the T-shaped tubes 3, manual adjustment is required each time, which easily leads to deviations during the manual adjustment process. The inconsistent spacing results of each adjustment affect the detection work.

[0054] When the first and second mounting brackets 38 and 39 are engaged with the limiting rod 59 and the limiting groove 60, the first and second mounting brackets 38 and 39 stop moving. Then, under the contraction of the telescopic member 36, the push plate 40 starts to push the T-shaped tube 3 to move. The T-shaped tube 3 in the first position begins to contact and squeeze the inclined position of the limiting plates 44 on both sides. Then, the limiting plates 44 on both sides move and the T-shaped tube 3 moves to the vacant position of the first and second mounting plates 45 and 46. When the electric push rod 37 contracts, the squeezing of the T-shaped tube 3 is cancelled. At this time, the T-shaped tube 3 falls down along the guide plate 47 to the top of the support due to gravity. During the process, the limiting plate 44 drives the mounting block 49 to move, and clamps the edges of the first and second mounting brackets 38 and 39 through the clamping block 52 connected to the torsion spring 51, limiting The position of the limit plate 44 is controlled to prevent it from restoring, and as the limit plate 44 moves, the limit plate 44 drives the driving rack 56 to move, and the driving rack 56 drives the first rack 53 downward through the first gear 55, and the first rack 53 drives the second rack 57 downward and randomly drives the second gear 58 to rotate. As the second gear 58 rotates, the horizontal slide 4 automatically adjusts its position under the drive of the double-headed screw. At the same time, the horizontal slide 4 drives the second mounting brackets 39 on both sides to automatically adjust their positions through the cooperation of the limit rod 59 and the limit groove 60; when the inspection processing is completed, the operation box is first lifted and then the moving rod 63 is driven by the sprocket chain transmission member to move along the rectangular route in the return groove plate 62. During the process, the pipe unloading rack 64 first moves horizontally to fix the T-shaped pipe 3 with the end portion, and then moves upward to remove the T-shaped pipe 3 from the support column. Finally, during the backward movement, the T-shaped pipe 3 is separated from the pipe unloading rack 64 due to the obstruction of the blocking rod 66 and falls into the release agent box 65 for collection;

[0055] It should be noted that the elastic force generated by the contraction of the first spring 43 is relatively small, thereby ensuring that the T-shaped tube 3 can slide down under the action of its own gravity after the electric push rod 37 removes the pressure. When it is necessary to replace the T-shaped tube 3 of a different specification, it is necessary to manually rotate the rotating sleeve to restore the horizontal slide 4 to its initial position, and then press the block 52 on the limit member 48 to restore the limit plate 44. Finally, restore the second mounting brackets 39 on both sides to continue working and automatically identify the new size of the T-shaped tube 3 to adjust the position of each component.

[0056] As a preferred embodiment of this embodiment, the rotating mechanism 34 includes a cylindrical rod 69, which is sleeved with a second spring 67 and connected to the third rack 68 and the horizontal slide 4 at the top and bottom respectively; a vertical plate 71 connected to the horizontal slide 4 and connected to a round rod 70; a third gear 72 connected to the round rod 70 and cooperating with the third rack 68 for transmission; and a bevel gear 73 connected to the round rod 70 and the support column, which is meshed with each other and is used to drive the support column to rotate.

[0057] The auxiliary mechanism 35 includes a first ventilation pipe 75 connected to the outside of the nozzle 26 and connected to a second ventilation pipe 76 via a connecting seat 74; a blower unit 78 connected to the second ventilation pipe 76 and driven by the output end of a motor 77; a water filter plate 79 connected between the second ventilation pipe 76 and the first ventilation pipe 75 and synchronously driven by the output end of the motor 77 via a belt drive; and a drainage rod 61 connected to the second arc-shaped electric slider and used to squeeze water out of the water filter plate 79.

[0058] In this embodiment, the rotating mechanism 34 is provided so that the vertical direction of the T-tube 3 can be inspected during the inspection process. In addition, the chemical agent sprayed from the nozzle 26 can be more concentrated under the action of the auxiliary mechanism 35 to prevent it from diffusing outward. The large amount of water vapor generated by the reaction is also collected in time by the auxiliary mechanism 35 to prevent the formation of a water film adhering to the outer wall of the T-tube 3 and affecting the reaction.

[0059] In detail, when the camera detects a part that needs to be processed, the nozzle 26 first sprays out chemicals, and at the same time, the motor 77 drives the blower unit 78 to form an annular air wall around the sprayed chemicals through the second ventilation pipe 76 and the first ventilation pipe 75 to prevent the chemicals from being sprayed to other positions. In response, the motor 77 drives the blower unit 78 to reverse and inhale the generated water vapor and absorb it through the water filter plate 79; when it is necessary to inspect the vertical tube body of the T-shaped tube 3, first adjust the position of the nozzle 26 and the semicircular arc slide rail to prevent interference with the T-shaped tube 3, and then drive the operation box downward by the cylinder. During the process, the operation box squeezes the top of the third rack 68, and the third rack 68 moves downward and drives the round rod 70 to rotate through the third gear 72. The round rod 70 drives the support column to rotate through two mutually meshing bevel gears 73, and the support column drives the T-shaped tube 3 to rotate for detection. After the detection is completed, the second spring 67 drives the third rack 68 to reset as the operation box resets;

[0060] It should be noted that, when the support column rotates, the friction between the support column and the threaded sleeve is small, so the support column will not drive the threaded sleeve to rotate; the blower unit 78 is a metal frame with multiple fan blades installed.

[0061] Working steps

[0062] Before surface inspection of the polished high-temperature brazed T-tube 3, multiple T-tubes 3 of the same batch are respectively inserted into the corresponding support columns 6, and then multiple air inlet valves 11 are opened, and gas is injected into the multiple connecting cavities 8 through an external air pump, so that the two limiting airbags 10 at the corresponding positions are expanded and clamped on the two ends of the T-tube 3 at the same height, so as to limit the T-tube 3, realize subsequent stable detection, realize accurate detection of scratches on the outer wall of the T-tube 3, and improve the detection accuracy. In addition, through the limiting method of the expansion of the limiting airbag 10, the limiting operation can be completed for T-tubes 3 of different sizes. At the same time, by spirally rotating the threaded sleeve 7, the height of the support column 6 is adjusted, and then the T-tubes 3 of different lengths are adapted for use, thereby improving the practicality of the entire lathe.

[0063] When the lengths of multiple T-shaped tubes 3 are different, by rotating the rotating rod at the corresponding position, the rotating sleeve 14 drives the corresponding double-headed screw 13 to rotate synchronously, so that the two adjacent horizontal slides 4 at the corresponding position move away from or close to each other, adapting to the length of the T-shaped tube 3 at the corresponding position, thereby achieving unified and centralized inspection of T-shaped tubes 3 of different sizes and beautifying the outer tube wall, thereby improving the finishing efficiency of the T-shaped tube 3.

[0064] After fixing the T-tubes 3 of multiple high-temperature brazing parts on the corresponding support columns 6 respectively, the horizontal electric sliders 16 on both sides are controlled to operate synchronously. Under the guidance of the horizontal linear slide 15, the camera 25 is moved in the horizontal direction through the connection between the incomplete arc slide 17 and the semi-circular arc slide 19. At the same time, the operation of the first arc electric slider 18 drives the entire semi-circular arc slide 19 to rotate, thereby indirectly driving the camera 25 to rotate, and cooperates with the operation of the second arc electric slider 21 to drive the camera 25 to further move in a circular motion, screwing in the outer wall of the two ends at the same height on the T-tube 3 and identifying scratches, so as to make up for the gap on the incomplete arc slide 17 and compensate for the recognition blind spot of the T-tube 3. At the same time, when the semi-circular arc slide 19 moves to the joint position on the T-tube 3, the second arc electric slider 21 is used to rotate the camera 25. An arc-shaped electric slider 18 operates and drives the semi-circular slide rail 19 to rotate to one side of the T-shaped tube 3 to avoid cross-contact between the semi-circular slide rail 19 and the T-shaped tube 3, and drives the camera 25 to rotate and shoot the outer wall of the lower end of the T-shaped tube 3 through the spherical seat 24 according to the rotation principle of the spherical camera, thereby realizing the recognition of scratches on the outer wall of the high-temperature brazing part T-shaped tube 3. If the camera 25 transmits the shooting picture to the controller 30 and the controller 30 recognizes and distinguishes the presence of scratches, the controller 30 controls the second valve 27 to open, and sprays the chemical reagent on the corresponding position on the T-shaped tube 3 through the nozzle 26. Since there are sharp edges at the scratches, the corrosion rate is fast, so that the small scratches can be completely eliminated after chemical polishing, thereby improving the surface gloss of the T-shaped tube 3, and realizing the true meaning of the finishing treatment of the high-temperature brazing part T-shaped tube 3.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
