Description

Technical Field

[0001] This invention relates to the field of turning equipment, and more specifically, to a turning equipment and method for dog-bone shaped pipe fittings. Background Technology

[0002] Dog-bone shaped tubing, also known as bar pins, is used in the front subframe of automobiles to ensure that the subframe can be firmly connected to the main frame, while also reducing vibration and noise and enhancing vehicle safety. Dog-bone shaped tubing requires turning during its production process.

[0003] However, during turning, the workpiece and the cutting tool come into contact with each other, generating a great deal of heat. Coolant is needed to cool the cutting tool, reduce wear, and extend tool life. But during the cutting process, the coolant flows continuously, and some of it is not cooled down in time and is drained away, resulting in a large amount of coolant being needed during cutting and increasing production costs. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a turning equipment and method for dog bone shaped pipe fittings.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A turning device for dog bone-shaped pipe fittings includes a waste collection frame, a mounting plate fixedly connected to one side of the waste collection frame, a turning mechanism and a support rail fixedly connected to the front and rear sides of one side of the mounting plate respectively, a clamping assembly fixedly connected to the side of the mounting plate away from the support rail, and an intermittent assembly fixedly connected to one side of the waste collection frame.

[0007] The intermittent assembly includes a liquid storage tank fixed to the rear side of the waste collection frame. A piston cylinder is fixedly connected to the upper surface of the liquid storage tank. A first one-way valve and a second one-way valve are symmetrically opened on the outer surface of the piston cylinder. A water inlet pipe is connected to the bottom of the second one-way valve, and a guide pipe is connected to the top of the first one-way valve. A piston is slidably connected inside the piston cylinder, and a driving component for driving its reciprocating movement is connected to one side of the piston.

[0008] Furthermore, the driving component includes a first driving motor fixed to one side of the liquid storage tank. A crank connecting rod is fixedly connected to the output end of the first driving motor. A first hinge rod is hinged to the outer surface of the crank connecting rod. One side of the first hinge rod is hinged to one side of the piston. Two support rods are slidably connected to the outer surface of the support rail. A top plate is fixedly connected to the top of the support rod. A collection assembly is fixedly connected to the top of the top plate. An anti-diffusion assembly is fixedly connected to one side of the two support rods. One end of the guide pipe passes through the top plate and is fixed to each other. The flow direction of the second one-way valve is from the inlet pipe to the piston cylinder, and the flow direction of the first one-way valve is from the piston cylinder to the guide pipe.

[0009] Furthermore, the collection assembly includes a fan frame fixed to the top of the top plate and a second gear fixed to the top of the crank connecting rod. A drive shaft is rotatably connected through the upper surface of the fan frame. A first gear and a fan impeller are fixedly connected to the top and bottom of the drive shaft, respectively. A drive belt is sleeved on the outer surface of the second gear and the first gear. A drain pipe is fixedly connected to the outer surface of the fan frame. The second gear is connected to an external oil mist treatment mechanism.

[0010] Furthermore, the second gear and the output shaft of the first drive motor are located on the same axis, and the guide tube is located in the middle of the transmission belt.

[0011] Furthermore, the anti-diffusion component includes an air pump base fixed to one side of the support rod, a double-headed air pump fixedly connected to one side of the air pump base, an air outlet pipe fixedly connected to both output ends of the double-headed air pump, and multiple air nozzles fixedly connected to the outer surface of the air outlet pipe, the air nozzles being inclined.

[0012] Furthermore, the clamping assembly includes a second drive motor fixed to one side of the mounting plate. The output end of the second drive motor passes through the mounting plate and is fixedly connected to a circular frame. A rotating ring is slidably connected to the outer surface of the circular frame. Two second hinge rods are hinged to the inner surface of the rotating ring. A mounting bracket is hinged to one end of each of the two second hinge rods. A pressing block is fixedly connected to the bottom of the mounting bracket. A telescopic rod is slidably connected inside the pressing block. A contact block is fixedly connected to the bottom of the telescopic rod. A fifth spring is sleeved on the outer surface of the telescopic rod. The top and bottom of the fifth spring are fixedly connected to the pressing block and the telescopic rod.

[0013] Furthermore, a release component is fixedly connected to the inner surface of the circular frame, a side clamping component is provided inside the contact block, and through holes are symmetrically provided on the inner surface of the circular frame, with the second hinge rod passing through the interior of the through holes.

[0014] Furthermore, the side clamping assembly includes two through slots formed inside the contact block. A sleeve is slidably connected inside the through slots. A trapezoidal block is fixedly connected to the bottom of the sleeve. A second spring is fixedly connected to the inner bottom of the sleeve. A pressing rod is fixedly connected to the top of the second spring. A first spring is fixedly connected to the inner surface of the through slots. The pressing rod slides against the sleeve. The outer surface of the sleeve is fixedly connected to one side of the first spring.

[0015] Furthermore, the release assembly includes four connecting brackets fixed to the inner surface of the circular frame, a second ratchet rack fixed to both sides of the mounting bracket, and a fourth spring fixed to the top of the mounting bracket. The outer surface of the connecting bracket is fitted with a third spring and a first ratchet rack, and a C-shaped rod is fixedly connected to the same side of the two first ratchet racks.

[0016] The turning method for dog-bone shaped tubular fittings using a turning machine includes the following steps:

[0017] S: Insert the flat end of the dog bone fitting horizontally between the two contact blocks. The two sides of the flat end of the fitting contact the inclined side of the trapezoidal block. The two contact blocks separate from each other, and the fifth spring is stretched to generate elastic force to clamp the fitting.

[0018] S: Rotating the rotating ring pushes one end of the second hinge rod to move, which drives the extrusion block to approach the pipe fitting through the mounting bracket and extrudes the extrusion rod. The extrusion rod presses down on the second spring, and the elastic force of the second spring is applied to the trapezoidal block, so that the two trapezoidal blocks generate horizontal relative forces to clamp the two sides of the pipe fitting.

[0019] S: Turn on the second drive motor to rotate the entire circular frame, which in turn rotates the pipe fitting, and the turning mechanism begins to turn the pipe fitting;

[0020] S: Start the first drive motor to drive the crank connecting rod to rotate. With the cooperation of the first hinge rod and the piston, the coolant inside the liquid storage tank can be intermittently delivered to the inside of the guide pipe to flush and cool the cutting part.

[0021] S: Simultaneously, the second gear rotates with the crank and connecting rod, and through the transmission belt, the first gear rotates synchronously, driving the fan impeller to rotate and generate suction to adsorb the water vapor generated during cutting. The dual-head air pump sprays air outward through the nozzle, forming an air wall around the working area, improving the water vapor absorption effect of the fan impeller.

[0022] S: After cutting is complete, pulling the two C-shaped rods can quickly release the first and second ratchet racks, and the two extrusion blocks will separate from each other through transmission. At this time, the pipe can be pulled out from between the two contact blocks.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This solution incorporates an intermittent component, enabling the piston to reciprocate within the piston cylinder, continuously drawing and pushing liquid into the cylinder. This allows the guide pipe to intermittently spray coolant, effectively reducing the amount of coolant sprayed during cutting of the pipe without sacrificing heat exchange and cooling. This significantly reduces coolant usage, improves heat exchange efficiency, lowers cutting costs, and achieves energy savings.

[0025] 2. This solution incorporates a collection component. The water vapor from the evaporation of the coolant is drawn into the fan frame by the suction of the fan impeller. The water vapor then passes through the fan frame into the drain pipe and enters the external oil mist treatment mechanism to treat the coolant water vapor. This prevents the coolant water vapor from spreading to the surrounding area and prevents workers from inhaling the coolant water vapor, thus ensuring the health and safety of workers during their work.

[0026] 3. This solution incorporates anti-diffusion components. The airflow from the two sets of jet nozzles forms an inverted V-shape, creating two air walls at the bottom of the top plate. When the water vapor from the coolant evaporates and diffuses to the surroundings, the airflow instantly transports the water vapor to the bottom of the fan frame upon contact with the air walls. The airflow then carries the water vapor to the inside of the drain pipe via the fan impeller. This maximizes the collection of coolant water vapor and effectively prevents water vapor from spreading to the surroundings from a distance from the fan frame, further ensuring the health of the staff.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1 to 10 A turning device for dog bone-shaped pipe fittings includes a waste collection frame 1, a mounting plate 2 fixedly connected to one side of the waste collection frame 1, a turning mechanism 3 and a support rail 4 fixedly connected to the front and rear sides of one side of the mounting plate 2 respectively, a clamping assembly 6 fixedly connected to the side of the mounting plate 2 away from the support rail 4, and an intermittent assembly 5 fixedly connected to one side of the waste collection frame 1.

[0051] like Figure 6 and Figure 7 As shown, the intermittent assembly 5 includes a liquid storage tank 59 fixed to the rear side of the waste collection frame 1. A piston cylinder 512 is fixedly connected to the upper surface of the liquid storage tank 59. A first one-way valve 56 and a second one-way valve 57 are symmetrically opened on the outer surface of the piston cylinder 512. A water inlet pipe 58 is connected to the bottom of the second one-way valve 57. A guide pipe 53 is connected to the top of the first one-way valve 56. A piston 514 is slidably connected inside the piston cylinder 512. A drive component for driving its reciprocating movement is connected to one side of the piston 514.

[0052] The driving components include a first drive motor 510 fixed to one side of the liquid storage tank 59, a crank connecting rod 511 fixedly connected to the output end of the first drive motor 510, a first hinge rod 513 hinged to the outer surface of the crank connecting rod 511, one side of the first hinge rod 513 hinged to one side of the piston 514, two support rods slidably connected to the outer surface of the support rail 4, a top plate 52 fixedly connected to the top of the support rods 51, a collection assembly 54 fixedly connected to the top of the top plate 52, an anti-diffusion assembly 55 fixedly connected to one side of the two support rods 51, one end of the guide pipe 53 passing through the top plate 52 and fixed to each other, the flow direction of the second one-way valve 57 is from the water inlet pipe 58 to the piston cylinder 512, and the flow direction of the first one-way valve 56 is from the piston cylinder 512 to the guide pipe 53.

[0053] When cutting the dog-bone shaped pipe, the first drive motor 510 is started to drive the crank connecting rod 511 to rotate. The crank connecting rod 511 drives one end of the first hinge rod 513 to move in a circle, thereby pulling the piston 514 to move back and forth inside the piston cylinder 512. When the piston 514 moves towards the crank connecting rod 511, the inside of the piston cylinder 512 is under negative pressure. The coolant inside the liquid storage tank 59 is drawn into the inside of the piston cylinder 512 through the second one-way valve 57 and the water inlet pipe 58. When the piston 514 moves to the other side, the coolant inside the piston cylinder 512 is pushed into the inside of the guide pipe 53 through the first one-way valve 56 and sprayed out through the guide pipe 53. In this way, the piston 514 moves back and forth, and the guide pipe 53 sprays coolant intermittently. This can effectively reduce the amount of coolant sprayed when cutting the pipe without sacrificing heat exchange and cooling, effectively reducing the use of coolant, with high heat exchange efficiency, reducing the cost during cutting, and achieving the effect of energy saving.

[0054] like Figure 8 and Figure 9 As shown, the collection assembly 54 includes a fan frame 541 fixed to the top of the top plate 52 and a second gear 544 fixed to the top of the crank connecting rod 511. A drive shaft 542 is rotatably connected through the upper surface of the fan frame 541. A first gear 543 and a fan impeller 547 are fixedly connected to the top and bottom of the drive shaft 542, respectively. A drive belt 546 is sleeved on the outer surface of the second gear 544 and the first gear 543. A drain pipe 545 is fixedly connected to the outer surface of the fan frame 541. The second gear 544 is connected to an external oil mist treatment mechanism.

[0055] The second gear 544 and the output shaft of the first drive motor 510 are on the same axis, and the guide tube 53 is located in the middle of the transmission belt 546.

[0056] At the moment the coolant comes into contact with the cutting tool, the coolant absorbs a large amount of heat, causing its temperature to rise. This results in some of the coolant evaporating, and the water vapor from the evaporated coolant can be inhaled into the lungs of workers, affecting their health.

[0057] When the first drive motor 510 drives the crank connecting rod 511 to rotate, the crank connecting rod 511 synchronously drives the second gear 544 to rotate. The second gear 544 drives the two first gears 543 to rotate synchronously through the transmission belt 546. The first gears 543 drive the fan impeller 547 to rotate synchronously through the transmission shaft 542, which generates suction at the bottom of the fan frame 541. When the water vapor of the coolant rises to the bottom of the fan frame 541, it will be sucked into the interior of the fan frame 541 by the suction of the fan impeller 547. The water vapor then enters the interior of the drain pipe 545 through the fan frame 541 and enters the external oil mist treatment mechanism through the drain pipe 545 to treat the water vapor of the coolant. This can prevent the water vapor of the coolant from spreading to the surroundings and prevent the workers from inhaling the water vapor of the coolant into their bodies, thus ensuring the health and safety of the workers during work.

[0058] like Figure 10 As shown, the anti-diffusion component 55 includes an air pump base 551 fixed to one side of the support rod 51. A double-headed air pump 552 is fixedly connected to one side of the air pump base 551. Both output ends of the double-headed air pump 552 are fixedly connected to an air outlet pipe 553. Multiple air nozzles 554 are fixedly connected to the outer surface of the air outlet pipe 553. The air nozzles 554 are inclined.

[0059] However, during the cutting process, there is a distance between the cutting point and the bottom of the fan frame 541. As the water vapor rises and moves, it gradually diffuses to the surroundings, causing a small portion of the water vapor to be unable to be drawn into the interior of the fan frame 541.

[0060] After the first drive motor 510 starts, the dual-head air pump 552 is turned on simultaneously. The dual-head air pump 552 works to deliver airflow into the air outlet pipe 553. The airflow is then quickly ejected through multiple jet nozzles 554. The two sets of jet nozzles 554 spray powerful airflow towards the bottom of the fan frame 541. The trajectory of the airflow from the two sets of jet nozzles 554 forms an inverted V shape, creating two air walls at the bottom of the top plate 52. When the water vapor from the coolant evaporates and diffuses to the surroundings, the water vapor comes into contact with the air walls, and the airflow transports the water vapor to the bottom of the fan frame 541. The water vapor is then transported to the drain pipe 545 through the fan impeller 547. This maximizes the collection of coolant water vapor and effectively prevents water vapor that is far from the fan frame 541 from spreading to the surroundings, further ensuring the health of the staff.

[0061] like Figure 3 - Figure 5As shown, the clamping assembly 6 includes a second drive motor 61 fixed to one side of the mounting plate 2. The output end of the second drive motor 61 passes through the mounting plate 2 and is fixedly connected to a circular frame 62. A rotating ring 63 is slidably connected to the outer surface of the circular frame 62. Two second hinge rods 65 are hinged to the inner surface of the rotating ring 63. A mounting bracket 610 is hinged to one end of each of the two second hinge rods 65. A pressing block 69 is fixedly connected to the bottom of the mounting bracket 610. A telescopic rod 66 is slidably connected inside the pressing block 69. A contact block 612 is fixedly connected to the bottom of the telescopic rod 66. A fifth spring 611 is sleeved on the outer surface of the telescopic rod 66. The top and bottom of the fifth spring 611 are fixedly connected to the pressing block 69 and the telescopic rod 66.

[0062] A release component 68 is fixedly connected to the inner surface of the circular frame 62. A side clamping component 67 is provided inside the contact block 612. A through hole 64 is symmetrically provided on the inner surface of the circular frame 62. The second hinge rod 65 passes through the interior of the through hole 64.

[0063] When clamping dog-bone shaped pipe fittings, the two ends of the fitting are flat, and traditional three-jaw chucks cannot clamp the two ends of the fitting. This causes the dog-bone shaped pipe fitting to shake during cutting, resulting in a decrease in the quality of pipe cutting and an increase in the defect rate.

[0064] With the clamping assembly 6 in place, the flat end of the dog-bone shaped pipe fitting is inserted between two contact blocks 612. The two contact blocks 612 are spread apart and move away from each other. The telescopic rod 66 moves and stretches the fifth spring 611, generating elastic force. The elastic force is applied to the contact blocks 612 to initially clamp the dog-bone shaped pipe fitting. At this time, hands can be freed, avoiding manual material handling and preventing accidental squeezing of the hands by the contact blocks 612 during pipe clamping, thus improving the safety of the preparation work. Then, the rotating ring 63 is rotated, which pushes one end of the second hinge rod 65 to move. The two second hinge rods 65 push the mounting bracket 610 to move the extrusion block 69 towards the center, further stretching the fifth spring 611. The extrusion block 69 extrudes the contact blocks 612, effectively clamping the pipe fitting through the two contact blocks 612.

[0065] like Figure 5 As shown, the side clamping assembly 67 includes two through slots 671 formed inside the contact block 612. A sleeve 676 is slidably connected inside the through slot 671. A trapezoidal block 675 is fixedly connected to the bottom of the sleeve 676. A second spring 674 is fixedly connected to the inner bottom of the sleeve 676. A pressing rod 673 is fixedly connected to the top of the second spring 674. A first spring 672 is fixedly connected to the inner surface of the through slot 671. The pressing rod 673 slides against the sleeve 676. The outer surface of the sleeve 676 is fixedly connected to one side of the first spring 672.

[0066] As the extrusion block 69 moves toward the contact block 612, it comes into contact with the top of the extrusion rod 673, pushing the rod into the sleeve 676 and squeezing the second spring 674 to generate elastic force, which is then applied to the trapezoidal block 675. Since the pipe fitting is in contact with the inclined side of the trapezoidal block 675, and the two sides of the flat end of the pipe fitting are in contact with the inclined side of the trapezoidal block 675 when the flat end is inserted between the two contact blocks 612, the two trapezoidal blocks 675 generate a horizontal opposing force applied to the pipe fitting, thus clamping both sides of the pipe fitting in four directions. This further improves the stability of the pipe fitting during cutting. Simultaneously, when the pipe fitting is inserted into the contact block 612, the two trapezoidal blocks 675 can limit its position, ensuring it is centered in the circular frame 62, improving the quality of cutting and reducing the defect rate.

[0067] like Figure 4 As shown, the release assembly 68 includes four connecting brackets 681 fixed to the inner surface of the circular frame 62, second ratchet racks 684 fixed to both sides of the mounting bracket 610, and a fourth spring 686 fixed to the top of the mounting bracket 610. The outer surface of the connecting bracket 681 is fitted with a third spring 682 and a first ratchet rack 683. A C-shaped rod 685 is fixedly connected to the same side of the two first ratchet racks 683.

[0068] After the pipe fitting is cut, the traditional three-jaw chuck requires one hand to turn the handle away from the operating area while the other hand holds the pipe fitting, which takes a long time to disassemble and assemble and is relatively inconvenient to operate.

[0069] After the pipe fitting is cut, pull the two C-shaped rods 685 away from each other. The first ratchet rack 683 and the second ratchet rack 684 disengage, and the stretched fourth spring 686 quickly returns to its original position, causing the mounting bracket 610 and contact block 612 to reset. The second hinge rod 65 also pushes the rotating ring 63 to rotate outside the circular frame 62. At this time, the fifth spring 611 remains stretched, applying a certain force to one end of the pipe fitting to prevent it from falling off. Finally, pull the pipe fitting out from between the two contact blocks 612. (Note: The last sentence about clamping is incomplete and likely refers to a different process.) The moving mounting bracket 610 stretches the fourth spring 686, simultaneously causing the second ratchet 684 to move to one side of the first ratchet 683. The inclined edge of the teeth of the second ratchet 684 slides against the inclined edge of the teeth of the first ratchet 683. After the clamping block 69 clamps the second ratchet 684, it cannot move in the opposite direction under the action of the first ratchet 683. After the clamping block 69 clamps the pipe fitting by pressing against the contact block 612, the clamping block 69 is also fixed. Therefore, when removing the pipe fitting from the equipment, the operation is simpler, the time is shorter, and the cutting efficiency is effectively improved.

[0070] A turning method for a dog-bone shaped tubular fitting using a turning machine includes the following steps:

[0071] S1: Insert the flat end of the dog bone tube horizontally between the two contact blocks 612. The two sides of the flat end of the tube contact the inclined side of the trapezoidal block 675. The two contact blocks 612 separate from each other. The fifth spring 611 is stretched to generate elastic force to clamp the tube.

[0072] S2: Rotating the rotating ring 63 pushes one end of the second hinge rod 65 to move, which drives the extrusion block 69 to approach the pipe through the mounting bracket 610 and extrudes the extrusion rod 673. The extrusion rod 673 presses down on the second spring 674. The elastic force of the second spring 674 is applied to the trapezoidal block 675, so that the two trapezoidal blocks 675 generate horizontal relative forces to clamp the two sides of the pipe.

[0073] S3: Turn on the second drive motor 61 to drive the circular frame 62 to rotate as a whole, which in turn drives the pipe to rotate, and the pipe is then turned by the turning mechanism 3.

[0074] S4: Start the first drive motor 510 to drive the crank connecting rod 511 to rotate. With the cooperation of the first hinge rod 513 and the piston 514, the coolant inside the liquid storage tank 59 can be intermittently delivered to the guide pipe 53 to flush and cool the cutting part.

[0075] S5: Simultaneously, the second gear 544 rotates with the crank connecting rod 511, and is driven by the transmission belt 546. The first gear 543 rotates synchronously, driving the fan impeller 547 to rotate and generate suction to adsorb the water vapor generated during cutting. The dual-head air pump 552 sprays air outward through the nozzle 554, forming an air wall around the working area, improving the water vapor absorption effect of the fan impeller 547.

[0076] S6: After cutting is completed, pulling the two C-shaped rods 685 can quickly release the first ratchet 683 and the second ratchet 684. The two extrusion blocks 69 are separated from each other through transmission. At this time, the pipe can be pulled out between the two contact blocks 612.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.

7. A turning method applicable to the dog-bone shaped pipe turning equipment of claim 6, characterized in that, Includes the following steps: S1: Insert the flat end of the dog bone tube horizontally between the two contact blocks (612). The two sides of the flat end of the tube contact the inclined side of the trapezoidal block (675). The two contact blocks (612) separate from each other. The fifth spring (611) is stretched to generate elastic force to clamp the tube. S2: Rotating the rotating ring (63) pushes one end of the second hinge rod (65) to move, and through the mounting bracket (610) drives the extrusion block (69) to approach the pipe and extrude the extrusion rod (673). The extrusion rod (673) presses down on the second spring (674). The elastic force of the second spring (674) is applied to the trapezoidal block (675), so that the two trapezoidal blocks (675) generate horizontal relative forces to clamp the two sides of the pipe.
