Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal joint manufacturing, and particularly relates to a device for producing and processing automobile brake oil pipe metal joints. BACKGROUND

[0002] The brake oil pipe metal joint is a core connecting piece in a pneumatic brake system, is used for accurately connecting brake hard pipes, hoses and brake master cylinders, calipers, wheel cylinders and proportional valves, guarantees the sealing transmission of brake fluid under high pressure conditions, and is a key part for maintaining the stability and safety of the brake system. The core value of the brake oil pipe metal joint lies in the structural strength and precise cooperation of the metal material, which can resist the instantaneous high pressure of the brake system, vehicle vibration and external corrosion, and can prevent leakage.

[0003] In the large-scale production process of the intelligent manufacturing equipment of the metal joint, the cutting processing of the metal pipe is a core pre-process, and the machining quality directly affects the precision of the subsequent cutting and tapping processes and the product performance of the final metal joint. The existing metal joint manufacturing equipment generally only has the function of cutting the metal pipe to a fixed length, and the cutting end face of the metal pipe is not polished and cleaned after cutting. During the cutting process of the metal pipe, the high-speed friction between the cutting saw blade and the metal pipe can cause a large amount of burrs and flash on the cutting end face, and the end face can also have problems such as insufficient flatness, local depression or protrusion. If these defects are not treated in time, the burrs can affect the cutting precision of the tool in the subsequent cutting and tapping processes, and can cause irregular thread processing, too large or too small fitting clearance, and thus reduce the assembly precision and connection stability of the metal joint. In severe cases, the burrs can also scratch the tool, increase the tool wear and replacement cost, and interrupt the production process. In addition, the metal scraps and impurities remaining on the cutting end face can be mixed into the machining surface in the subsequent processes, causing secondary scratches and affecting the surface quality of the metal joint. Especially for the metal joint with high sealing requirement, the end face defects can directly cause the sealing performance to fail, and cannot meet the use requirement. SUMMARY

[0008] Preferably, the cutting cooling mechanism comprises a plurality of flow-through members fixedly connected to the inside of the watering box, an inner pipe fixedly connected to the inside of each flow-through member, a watering pipe in communication with the inner pipe, and one end of the watering pipe away from the inner pipe penetrating to the outside of the watering box.

[0009] Preferably, a vertical rod is rotatably connected to the inner pipe, one end of the vertical rod fixedly connected to the inside of the inner pipe is provided with a baffle, one end of the vertical rod fixedly connected to the outside of the inner pipe is provided with a bottom gear, an inner rail is fixedly connected to the bottom of the flow-through member, a rack is slidingly connected to the inside of the inner rail, the rack is in meshing arrangement with the bottom gear, a return spring is fixedly connected to the outer side wall of the rack, and one end of the return spring away from the rack is in contact with the inner wall of the inner rail.

[0010] Preferably, the mechanical conveying mechanism includes sluices formed on both sides of the base plate, with a left telescopic rod and a right telescopic rod fixedly connected to the sluices on both sides respectively. A left plate and a right plate are slidably connected to the sluices on both sides respectively. The end of the left telescopic rod is fixedly connected to the left plate, and the end of the right telescopic rod is fixedly connected to the right plate. A left conveying head is fixedly connected to the left plate. Multiple bottom telescopic rods are fixedly connected inside the right plate. The ends of the multiple bottom telescopic rods are fixedly connected to the right conveying head. A metal tube is slidably connected to both the left and right conveying heads. A conveying wheel is installed on both the left and right conveying heads.

[0011] Preferably, a vertical plate is fixedly connected to the outer side wall of the right conveyor head, and a horizontal magnetic plate is provided on the vertical plate.

[0012] Preferably, a drive motor is fixedly connected to the outer wall of the driving member, a large gear is fixedly connected to the output end of the drive motor, a small gear is sleeved on the outer wall of the rotating rod, the large gear and the small gear are meshed, a mounting bracket is fixedly connected to the outer wall of the horizontal plate, an air jet pipe is fixedly connected to the mounting bracket, the air jet pipe communicates with the interior of the rotating rod, and does not contact the inner wall of the rotating rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the setting of the grinding disc and other mechanisms, after the cutting process is completed, the grinding disc can be driven by the rotating rod to perform low-speed grinding and polishing on the two cut end faces of the metal tube. This can effectively remove burrs and flash from the end faces, correct the flatness deviation of the end faces, and make the end faces meet the processing requirements of subsequent cutting and tapping processes. The ground end faces can avoid interference from burrs to the cutting tools, ensure neat thread processing, and improve the assembly accuracy and connection stability of the metal joints. At the same time, the subsequent air blowing cleaning can thoroughly remove residual metal chips and impurities on the end faces and inside and outside the metal tubes, prevent secondary scratches, ensure the surface quality and sealing performance of the metal joints, and significantly improve the product qualification rate.

[0015] 2. Through the setting of water spray box and other mechanisms, the cooling water volume can be precisely controlled. When cutting thin-walled metal pipes at conventional speeds, the baffle flips at a small angle, spraying a small amount of cooling water, which can meet the cooling needs of the saw blade and avoid water waste. When cutting thick-walled metal pipes at high speeds, the baffle opens fully at 90 degrees, significantly increasing the cooling water volume. This can effectively remove the large amount of heat generated by the saw blade, preventing high-temperature deformation and accelerated wear of the saw blade, ensuring cutting accuracy while extending the service life of the saw blade. At the same time, during the grinding process, the air jet blows air at a 25-degree angle to the grinding disc to cool it down, which can effectively remove the heat generated during grinding, prevent the grinding disc from aging and losing accuracy due to high temperature, and extend the service life of the grinding disc. Throughout the entire cutting and grinding process, the cooling system can be dynamically matched with the grinding conditions according to parameters such as the wall thickness and material hardness of the brake oil pipe metal joint, making the entire manufacturing equipment more intelligent.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 13A processing apparatus for manufacturing metal connectors for automotive brake lines includes a machine tool 1. A base plate 2 is fixedly connected to the outer wall of the machine tool 1. A mechanical conveying mechanism is provided on the base plate 2. A rear support 11 is fixedly connected to the outer wall of the base plate 2. Slide rails are fixedly connected to both sides of the rear support 11. Hydraulic telescopic rods 14 are provided inside the slide rails on both sides. A driving component 13 and a side mounting plate 31 are slidably connected inside the slide rails on both sides. A cross plate 17 is fixedly connected to the outer wall of the driving component 13. A bearing is fixedly connected to the outer wall of the side mounting plate 31. 33. A rotating rod 19 is rotatably sleeved on the horizontal plate 17. The end of the rotating rod 19 away from the horizontal plate 17 is rotatably sleeved on the bearing 33. A double-end cutting and grinding mechanism for steel pipe is set on the rotating rod 19. The double-end cutting and grinding mechanism for steel pipe includes a cutting saw blade 22 installed on the rotating rod 19. Two grinding discs 21 are installed on the rotating rod 19. The two grinding discs 21 are located on both sides of the cutting saw blade 22. Air jet holes 23 are opened on both sides of the rotating rod 19. A blocking member 24 is slidably sleeved on both sides of the rotating rod 19. An outer ring 25 is rotatably connected to both blocking members 24.

[0033] A connecting plate 26 is fixedly connected to both outer rings 25. An installation plate is fixedly connected to the outer wall of the horizontal plate 17. A limiting member 27 is fixedly connected to the installation plate. A pressing spring 28 is sleeved on the outer wall of the limiting member 27. The limiting member 27 is slidably connected to the connecting plate 26. A magnetic block 34 is fixedly connected to the outer wall of the connecting plate 26.

[0034] Water spray boxes 37 are installed on both sides of the rotating rod 19. Covering rings 36 are rotatably connected to both sides of the water spray boxes 37. Hard water pipes 35 are connected to the covering rings 36. A water tank 12 is fixedly connected to the outer wall of the rear bracket 11. The end of the hard water pipe 35 away from the covering ring 36 is connected to the inside of the water tank 12. Multiple water inlet holes 38 corresponding to the hard water pipes 35 are opened on the water spray boxes 37. A cutting and cooling mechanism is set inside the water spray boxes 37.

[0035] The cutting and cooling mechanism includes multiple flow components 40 fixedly connected inside the water spray box 37. Each of the multiple flow components 40 has an inner tube 41 fixedly connected inside. A water spray pipe 39 is connected to the inner tube 41, and the end of the water spray pipe 39 away from the inner tube 41 extends to the outside of the water spray box 37.

[0036] A vertical rod 44 is rotatably connected through the inner tube 41. A baffle 42 is fixedly connected to one end of the vertical rod 44 inside the inner tube 41, and a bottom gear 47 is fixedly connected to the other end of the vertical rod 44 outside the inner tube 41. An inner rail 43 is fixedly connected to the bottom of the flow member 40. A rack 45 is slidably connected inside the inner rail 43. The rack 45 and the bottom gear 47 are meshed. A return spring 46 is fixedly connected to the outer wall of the rack 45. The end of the return spring 46 away from the rack 45 contacts the inner wall of the inner rail 43.

[0037] In this embodiment, when the equipment is running, the metal tube 10 for making metal joints is first installed on the left conveying head 7 and the right conveying head 8. The two work together to convey the metal tube 10. The length of the metal tube 10 required for each metal joint is a preset rated value. When the conveying wheel 9 on the left conveying head 7 and the right conveying head 8 rotates to convey the metal tube 10, the cutting point of the cutting saw blade 22 is used as the reference boundary. When the right end of the metal tube 10 held by the right conveying head 8 reaches the rated manufacturing length of the metal joint, the conveying wheel 9 automatically stops rotating (this is the prior art and will not be described in detail).

[0038] At this time, the two hydraulic telescopic rods 14 can be controlled to extend synchronously. Through the linkage of components such as the drive component 13, the horizontal plate 17, the side mounting plate 31, and the bearing 33, the entire cutting saw blade 22 is pushed downward. During the downward movement of the cutting saw blade 22, the operator starts the drive motor 15, which drives the large gear 16 to rotate at normal power. Since the large gear 16 and the small gear 20 are meshed, when the large gear 16 rotates, it will drive the rotating rod 19 to rotate rapidly through the small gear 20. At the same time, the rotating rod 19 drives the cutting saw blade 22 to rotate rapidly. During the downward movement, the rapidly rotating cutting saw blade 22 contacts the metal pipe 10 and completes the cutting operation.

[0039] While the rotating rod 19 drives the cutting saw blade 22 to rotate and cut the metal pipe 10, it simultaneously drives the water spray box 37 to rotate. The centrifugal force generated by the rotation of the water spray box 37 causes the rack 45 to overcome the elastic force of the return spring 46 and move a small distance to the right (see reference). Figure 11 Because the rack 45 and the bottom gear 47 are meshed, when the rack 45 moves to the right, it will drive the vertical rod 44 and the baffle 42 to complete a rotation of less than 90 degrees through the bottom gear 47. After the baffle 42 is rotated, it will no longer completely block the inner tube 41. The cooling water thrown into the inner tube 41 during the rotation of the water spray box 37 will enter the water spray pipe 39 through the gap opened by the baffle 42, and then drip onto the surface of the cutting saw blade 22 through the water spray pipe 39, so as to achieve the cooling treatment of the cutting saw blade 22 and avoid the cutting saw blade 22 from being affected by the high temperature generated during the cutting operation, which would affect the cutting accuracy and service life.

[0040] If the metal pipe 10 to be cut by the cutting saw blade 22 has a large wall thickness, the operator can control the power of the drive motor 15 to increase the power, causing the drive motor 15 to drive the large gear 16 to rotate at high speed. According to the above-mentioned meshing transmission principle, the large gear 16 will drive the rotating rod 19 to rotate at high speed through the small gear 20, thereby driving the cutting saw blade 22 to complete the cutting operation at a higher speed. While the rotating rod 19 drives the cutting saw blade 22 to rotate at high speed to cut, it simultaneously drives the water spray box 37 to rotate at high speed. The large centrifugal force generated by the high-speed rotation of the water spray box 37 causes the rack 45 to overcome the elastic force of the return spring 46 and move to the rightmost position of the inner rail 43. Because the rack 45 meshes with the bottom gear 47, when the rack 45 moves a large distance to the right, it will drive the vertical rod 44 and the baffle 42 to complete a 90-degree rotation through the bottom gear 47. After the baffle 42 rotates 90 degrees, it completely releases the blocking effect on the inner tube 41. According to the above cooling water transportation principle, the cooling water thrown into the inner tube 41 at this time will enter the water spray pipe 39 in large quantities through the opening opened by the 90-degree rotation of the baffle 42. Finally, it will drip onto the surface of the cutting saw blade 22 through the water spray pipe 39. The amount of cooling water is significantly increased compared to before, which can fully meet the cooling requirements of the cutting saw blade 22 when cutting the thick-walled metal pipe 10 at high speed.

[0041] After the cutting saw blade 22 cuts the right end of the metal tube 10 to the rated length for making the metal joint, the operator controls the left telescopic rod 3 and the right telescopic rod 5 to retract. When the left telescopic rod 3 retracts, it pulls the left plate 4 to the left, and when the right telescopic rod 5 retracts, it pulls the right plate 6 to the right. The left plate 4 and the right plate 6, through the left conveyor head 7 and the right conveyor head 8 respectively, drive the two ends of the cut metal tube 10 to separate to both sides. Then, the operator controls the hydraulic telescopic rod 14 to extend. The hydraulic telescopic rod 14 pushes the rotating rod 19 to continue to move downward until the two grinding discs 21 contact the two cut end faces of the metal tube 10 respectively. After the two grinding discs 21 contact the two cut end faces of the metal tube 10, the left telescopic rod 3 and the right telescopic rod 5 can be extended a very small distance again, thereby pushing the cut end face of the metal tube 10 on the left conveyor head 7 and the right conveyor head 8 to have a certain contact pressure with the grinding disc 21, which helps with subsequent grinding (refer to...). Figure 12 ).

[0042] At this time, the drive motor 15 is controlled to run at low power, so that the rotating rod 19 rotates at a relatively low speed (it should be noted that the centrifugal force generated by the rotating rod 19 driving the water spray box 37 to rotate at a low speed is insufficient to make the rack 45 overcome the elastic force of the return spring 46 to move. Therefore, when the grinding disc 21 contacts the cutting end face of the metal pipe 10 for grinding, the water spray pipe 39 does not spray cooling water, which can effectively avoid wasting cooling water). After the two cutting end faces of the metal pipe 10 contact the corresponding grinding disc 21, the rotating rod 19 drives the grinding disc 21 to rotate at a relatively low speed to grind and polish the two cutting end faces of the metal pipe 10.

[0043] Example 2: Please refer toFigure 1 - Figure 13 This embodiment further describes Example 1. The mechanical conveying mechanism includes sluices formed on both sides of the base plate 2. A left telescopic rod 3 and a right telescopic rod 5 are fixedly connected to the sluices on both sides respectively. A left plate 4 and a right plate 6 are slidably connected to the sluices on both sides respectively. The end of the left telescopic rod 3 is fixedly connected to the left plate 4, and the end of the right telescopic rod 5 is fixedly connected to the right plate 6. A left conveying head 7 is fixedly connected to the left plate 4. A plurality of bottom telescopic rods 32 are fixedly connected inside the right plate 6. The ends of the plurality of bottom telescopic rods 32 are fixedly connected to the right conveying head 8. A metal tube 10 is slidably connected to both the left conveying head 7 and the right conveying head 8. A conveying wheel 9 is installed on both the left conveying head 7 and the right conveying head 8.

[0044] A vertical plate 29 is fixedly connected to the outer wall of the right conveyor head 8, and a horizontal magnetic plate 30 is provided on the vertical plate 29.

[0045] A drive motor 15 is fixedly connected to the outer wall of the drive component 13. A large gear 16 is fixedly connected to the output end of the drive motor 15. A small gear 20 is sleeved on the outer wall of the rotating rod 19. The large gear 16 and the small gear 20 are meshed. A mounting bracket is fixedly connected to the outer wall of the horizontal plate 17. An air jet pipe 18 is fixedly connected to the mounting bracket. The air jet pipe 18 is connected to the interior of the rotating rod 19 and does not contact the inner wall of the rotating rod 19.

[0046] In this embodiment, while the grinding disc 21 grinds the cut end face of the metal tube 10, the operator turns on the suction pump inside the jet pipe 18 to draw external air into the rotating rod 19. When the right conveying head 8 drives the cut end face of the right metal tube 10 to contact the right grinding disc 21, the vertical plate 29 blocks the right end opening of the rotating rod 19 (see reference). Figure 12 This allows the external airflow drawn into the rotating rod 19 to be sprayed at a 25-degree angle onto the surfaces of the two grinding discs 21 through the jet holes 23 on the left and right sides, thereby cooling the grinding discs 21 and preventing the grinding discs 21 from being affected by high temperatures during the grinding operation, which would affect the grinding effect and their service life.

[0047] After the grinding operation is completed, the operator first controls the right telescopic rod 5 to continue to retract, and then controls the bottom telescopic rod 32 to extend. The bottom telescopic rod 32 pushes the metal tube 10 cut on the right side to the front side of the rotating rod 19 through the right conveying head 8. When the metal tube 10 on the right side reaches the front side of the rotating rod 19, the horizontal magnetic plate 30 moves to the front side of the magnetic block 34, and the distance between the two decreases. Under the action of the mutually repulsive magnetic force, the connecting plate 26 is pushed to overcome the elastic force of the pressing spring 28, and the two outer rings 25 are moved to the left. Since the outer rings 25 and the blocking member 24 are rotatably connected, the outer rings 25 will drive the blocking member 24 to move synchronously when they move with the connecting plate 26, until the blocking member 24 completes the blocking of the two air jet holes 23. After the air jet holes 23 are blocked, the suction airflow inside the rotating rod 19 is blown to the metal tube 10 in large quantities through the right side of the rotating rod 19, and the internal and external surfaces of the metal tube 10 are cleaned by blowing air to remove the impurities remaining inside and outside the metal tube 10.

[0048] After the right metal tube 10 is cleaned, the bottom telescopic rod 32 retracts, and the right metal tube 10 is reset by the right conveyor head 8. Then, the feed wheel 9 on the right conveyor head 8 starts to transport the right metal tube 10 into the machine tool 1, where the machine tool 1 completes the cutting and tapping process to prepare a metal joint. When the right metal tube 10 is completely in the machine tool 1, the feed wheel 9 on the left conveyor head 7 rotates to transport the metal tube 10 on the left conveyor head 7 back through the right conveyor head 8, and repeats the above complete set of operation process (all of the above are existing technologies and will not be elaborated on further).

[0049] Additional explanation: When the water spray box 37 rotates, it drives multiple water inlet holes 38 to rotate synchronously. When the water inlet holes 38 rotate to coincide with the opening end of the rigid water pipe 35, the cooling water inside the water tank 12 transported by the rigid water pipe 35 enters the water spray box 37 through the water inlet holes 38. At the same time, both the side mounting plate 31 and the connecting plate 26 are provided with detachable parts, which can realize the left and right separation of the side mounting plate 31 and the connecting plate 26. When it is necessary to replace the cutting saw blade 22, first remove the right rigid water pipe 35 from the water tank 12, then separate the side mounting plate 31 and remove the bearing 33 from the rotating rod 19, then remove the right side part of the connecting plate 26, and finally remove the grinding disc 21 and the water spray box 37 to complete the replacement of the cutting saw blade 22 (this is existing technology and will not be elaborated further).
