Description

Technical Field

[0001] This invention relates to the field of precision tube processing equipment, specifically a cutting and processing device for precision tube production in the automotive industry. Background Technology

[0002] In the automotive industry, precision tubing refers to tubular components used in critical parts of automotive powertrains, braking systems, and steering systems. These components possess high-precision dimensions, excellent mechanical properties, and good sealing performance. They are typically made of high-strength alloys or precision stainless steel, and require extremely high processing precision and surface quality. In automotive production, precision tubing needs to be cut to specific lengths according to assembly requirements. Cutting equipment enables the precision tubing to be cut to these specific lengths. Precision tube cutting equipment in the automotive industry mainly consists of a basic support structure, a fixing mechanism, a cutting mechanism, an adjusting mechanism, and a moving mechanism. The basic support structure provides a stable platform for the entire device, ensuring no shaking during processing; the fixing mechanism clamps the precision tubes to prevent dimensional deviations caused by vibration during cutting; the cutting mechanism cuts the tubes through high-speed rotation, and its accuracy directly determines the smoothness of the cut; the adjusting mechanism can adjust the cutting angle and depth according to the tube specifications to meet the processing requirements of different types of precision tubes; and the moving mechanism drives the workpiece or cutting components to move, enabling continuous batch production. Existing cutting and processing equipment cannot process the edges and corners of the cut after precision tubes are cut, resulting in burrs, flash, and other defects. These defects affect the accuracy of subsequent assembly. For example, in the pipe connections of automotive power systems or braking systems, burrs may lead to poor sealing, increased risk of leakage, and even accelerated wear of parts, reducing the safety and reliability of vehicle operation. The cut precision tubes need to be transferred to specialized chamfering equipment for secondary processing, which increases the process flow time and labor costs. Frequent process transfers not only reduce production efficiency but may also cause tube positioning deviations due to multiple handling, further affecting processing accuracy and making it difficult to meet the automotive industry's requirements for high efficiency and consistency in mass production. Summary of the Invention

[0003] The purpose of this invention is to provide a cutting and processing device for the production of precision tubes in the automotive industry, which solves the following technical problems: After the precision tube is cut, the edges and corners of the cut area cannot be processed. It needs to be transferred to a special chamfering equipment for secondary processing, which increases the process flow time and labor operation costs. This not only reduces production efficiency, but may also cause tube positioning deviation due to multiple handling, affecting processing accuracy and making it difficult to meet the high efficiency and consistency requirements of the automotive industry for mass production.

[0008] As a preferred embodiment of the present invention: the interior of the fixing block is provided with a plurality of evenly distributed sliding grooves, the outer wall of the connecting plate slidably connected to the interior sliding grooves of the fixing block, and an anti-slip pad is fixedly connected to one side of the clamping plate.

[0009] As a preferred embodiment of the present invention: a lead screw is rotatably connected inside the base, a drive motor is fixedly connected to one end of the lead screw, the outer wall of the lead screw is threadedly connected to the inside of the fixing block, two slide rails are fixedly connected to the top of the base, and the bottom of the fixing block is slidably connected to the outer wall of the slide rails.

[0013] The beneficial effects of this invention are: (1) The present invention fixes the tube by fixing the fixed block and the moving frame. The starting motor drives the cutting blade to rotate through the rotating shaft. Then, the hydraulic rod drives the lifting plate to descend, thereby completing the cutting of the precision tube. After the cutting is completed, as the hydraulic rod drives the lifting plate to descend, the fixed frame and the moving frame can be moved by the cooperation of the moving component. At the same time, the passive helical gear can be moved by the cooperation of the adjusting component and then mesh with the active helical gear. At this time, the rotating shaft can drive the grinding block to rotate. The grinding block can grind the edges and corners of the pipe by rotating, avoiding burrs at the cut, thereby improving the processing effect of the product.

[0014] (2) In this invention, the lowering of the lifting plate can drive the extrusion block to lower. The lowering of the extrusion block can drive the baffle to move through the cooperation of the protrusion. When the baffle extends, the lowering of the extrusion block can squeeze one side of the hinge, thereby allowing the hinge to extend, which in turn drives the fixed frame and the moving frame to move. The movement of the moving frame can drive the cut precision tube to move. The movement of the fixed frame can drive the lifting plate to move. When it moves to the end point, the lowering of the lifting plate can no longer touch the precision tube, and the grinding block just contacts one end of the precision tube. When the motor drives the grinding block to rotate, the chamfering of the precision tube can be completed. When the lifting plate rises, since the next cut is required, the position of the fixed block can be moved by the lead screw. As the lifting plate rises, the fixed frame and the moving frame are reset through the cooperation of the moving component. Then the fixed block drives the remaining precision tube to move to complete the next cut. During the chamfering process, the displacement distance is fixed, avoiding the decrease in accuracy caused by free movement of multiple workstations.

[0015] (3) The present invention can drive the extrusion plate to descend by lowering the lifting plate. With the cooperation of the fixed frame, when it descends to a certain extent, the extrusion plate begins to move. The movement of the extrusion plate drives the connecting plate to rotate, which in turn causes the moving plate to move, thereby making the passive helical gear mesh with the active helical gear. When it rises to a certain extent, the passive helical gear can be reset by the cooperation of the spring. After the passive helical gear is reset, when the rotating shaft drives the cutting blade to rotate, the grinding block cannot be rotated. The grinding block stops rotating, which not only reduces unnecessary energy consumption, but also avoids the grinding block rotation from causing accidental injury to the workers, and improves the safety of the working environment. (4) The present invention can drive the rotating block to rotate by starting the second motor. The rotation of the rotating block drives the second moving block to move through the connecting block. The movement of the second moving block drives the clamping plate to move through the second connecting plate. The clamping plate can fix the precision tube by moving. The stabilizer is equipped with rollers, which play a stabilizing role but cannot fix the precision tube. The moving frame is equipped with anti-slip pads, which can not only fix the precision tube but also prevent damage to it when fixing it. Attached Figure Description

Both sides of the inside of the lifting plate 22 are rotatably connected with a protrusion shaft 38. A passive helical gear 37 is slidably connected to the outer wall of the protrusion shaft 38 and meshes with the driving helical gear 36. Motor 31 drives worm 32 to rotate. Worm 32 rotates, which in turn drives worm wheel 33 to rotate. Worm wheel 33 rotates, which in turn drives shaft 34 to rotate. Shaft 34 rotates, which in turn drives cutting blade 35 and driving helical gear 36 to rotate. Driving helical gear 36 rotates, which in turn drives driven helical gear 37 to rotate.

The movement of the moving plate 43 can drive the passive helical gear 37 to move, so that the passive helical gear 37 meshes with the active helical gear 36.

The rotation of the convex shaft 38 can drive the grinding block 44 to rotate. The rotation of the grinding block 44 can chamfer both ends of the pipe. The moving component 5 includes a pressing block 51, the top of which is fixedly connected to the bottom side of the lifting plate 22.

The bottom of one mounting block 55 is fixedly connected to the top of the base 1, and the other mounting block 55 is fixedly connected to one side of the moving frame 13. The pressing block 51 is used to fix the baffle 53. When the lifting plate 22 is raised or lowered, it can drive the pressing block 51 to move down. When the pressing block 51 is lowered to a certain extent, it can press the baffle 53 to move through the cooperation of the protrusion 52, so that the baffle 53 extends out from the inside of the pressing block 51. When it extends, the pressing block 51 can press the top of one side of the hinge 54, so that the hinge 54 is extended. Since one of the hinges 54 is fixed to the top of the base 1, when the hinge 54 is extended, it can move the fixed frame 12 connected to it. The other hinge 54 is fixed to the moving frame 13. When it is extended, it can adjust the distance between the fixed frame 12 and the moving frame 13, and further drive the moving frame 13 to move. The moving distance between the fixed frame 12 and the moving frame 13 is 1:2. In this way, when the lifting plate 22 is lowered, it can avoid touching the precision tube.

The outer wall of the limit plate 49 is rotatably connected to the inside of the movable block 45. Movable block 45 is used to fix the grinding block 44. At the same time, movable block 45 can disassemble the grinding block 44 to replace it with different grinding blocks 44 to adapt to the processing of precision tubes of different diameters. The disassembly method can also fix movable block 45 to the grinding block 44 and disassemble movable block 45 from the electric telescopic rod 46. The electric telescopic rod 46 is used to drive movable block 45 to move. Movable block 45 can drive grinding block 44 to move by moving. During the rotation, grinding block 44 slowly moves to complete the chamfering of the pipe end. Spring 47 can drive movable plate 43 to return to its original position by elastic force. Limiting plate 48 prevents the passive helical gear 37 from falling out of the movable plate 43. Limiting plate 49 prevents grinding block 44 from accidentally falling out of movable block 45 during the grinding and chamfering process.

[0026] A damper 56 is fixedly connected to one side of the baffle 53. The end of the damper 56 away from the baffle 53 is fixedly connected to the inside of the compression block 51. The bottom of the side of the hinge 54 away from the mounting block 55 is fixedly connected to the inner wall of the fixing frame 12.

The bottom of the side of the baffle 53 near the mounting block 55 is fixedly connected to one side of the mounting block 55. The top of the side of the baffle 53 near the mounting block 55 is slidably connected to the inside of the mounting block 55. The damper 56 can drive the baffle 53 to reset through its elastic force. When the pressing block 51 descends to a certain extent, the baffle 53 can be extended through the protrusion 52. After the baffle 53 extends, it can drive the top of one side of the hinge 54 to move down, thereby extending it. When the pressing block 51 continues to descend, it disengages from the protrusion 52. At this time, the elastic force of the damper 56 drives the baffle 53 to reset and retract. At this time, the pressing block 51 can no longer drive the side of the hinge 54 to descend. Similarly, when it rises and reaches a specific position, it can drive the hinge 54 to reset.

[0027] The working principle of this invention is as follows: A precision tube is passed through the interior of the moving frame 13 and the stabilizing frame 14, with one end placed inside the fixed block 11. Starting motor 61 drives the rotating block 62 to rotate. The rotation of the rotating block 62, via the connecting block 63, drives the moving block 64 to move. The moving block 64 then drives the connecting plate 65 to move, subsequently moving the clamping plate 66 to complete the fixation of the precision tube. Starting motor 31 drives the worm gear 32 to rotate. The rotation of the worm gear 32, via the worm wheel 33, drives the rotating shaft 34 to rotate. The rotating shaft 34, through rotation, drives the cutting blade 35 to rotate. The hydraulic rod 21 drives the lifting plate 22 to descend. The descent of the lifting plate 22 drives the cutting blade 35 to descend. The cutting blade 35 rotates as it descends. The rotating mechanism can cut the precision tube by descending. After the cutting is completed, the lifting plate 22 continues to descend. The descent of the lifting plate 22 can drive the pressing block 51 to descend. After the pressing block 51 descends to a certain extent, it can drive the baffle 53 to move through the cooperation of the protrusion 52, thereby locking the top of one side of the hinge 54, so that one side of the hinge 54 moves synchronously with the pressing block 51. When one end of the hinge 54 descends, it can extend. Since one of the mounting blocks 55 is fixed to the top of the base 1, when the hinge 54 extends, it can drive the fixed frame 12 to move. The other mounting block 55 is fixed to one side of the moving frame 13, and similarly, it can drive the moving frame 13 to move. When it descends to a certain extent, it disengages from the protrusion 52, and at this time, the fixation of the hinge 54 is released. As the lifting plate 22 continues to descend, the pressing plate 41 can disengage from the groove of the fixed frame 12, and then the fixed frame 12 presses it, causing the pressing plate 41 to move. The movement of the pressing plate 41 drives the connecting plate 42 to rotate, which in turn drives the moving plate 43 to move. After the moving plate 43 moves, the passive helical gear 37 can mesh with the active helical gear 36. When the motor 31 drives the cutting blade 35 to rotate through the rotating shaft 34, it can also drive the active helical gear 36 to rotate. When the active helical gear 36 meshes with the passive helical gear 37, the rotation of the active helical gear 36 can drive the passive helical gear 37 to rotate. The rotation of the passive helical gear 37 can drive the convex shaft 38 to rotate, which in turn drives the grinding block 44 to rotate. During the chamfering process, the electric telescopic rod 46 drives the moving block 45 to move. The movement of the moving block 45 drives the grinding block 44 to move. The movement and rotation of the grinding block 44 can complete the chamfering of the precision tube end, improving the processing quality. After the end face is processed, the screw 15 drives the fixed block 11 to move. The movement of the fixed block 11 drives the precision tube to move, avoiding the collision between the lifting plate 22 and the precision tube during the rising process. The hydraulic rod 21 drives the lifting plate 22 to rise. Then, the adjustment component 4 and the moving component 5 work together to reset the fixed frame 12, the moving frame 13 and the grinding block 44. The precision tube that has been cut is removed from the moving frame 13. Then, the screw 15 drives the fixed block 11 to move for the next cut.

[0028] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
