Description

Technical Field

[0001] This invention is a turning equipment for automotive parts, belonging to the field of automotive parts processing technology. Background Technology

[0002] Turning, or lathe machining, is a part of mechanical processing. Before turning automotive parts, it is necessary to ensure that the rotation center of the workpiece coincides as closely as possible with the rotation center of the lathe spindle. Otherwise, workpiece eccentricity will lead to uneven cutting depth, resulting in a machining diameter that does not match the design value and cannot guarantee consistency. At the same time, the vibration caused by eccentricity will make the contact between the tool and the workpiece unstable, resulting in chatter marks and ripples on the machined surface, a decrease in surface finish, and the eccentric mass will generate unbalanced centrifugal force during high-speed rotation, causing strong vibration, affecting machining stability, and easily leading to production accidents, which is detrimental to safe production. Summary of the Invention

[0011] Furthermore, a calibration rod is inserted between the connecting blocks of the two support mechanisms, and a levelness measuring device is installed at the bottom of the calibration rod.

[0012] Furthermore, the levelness measuring device is one of a bubble level, an electronic level, or a laser level.

[0013] Furthermore, the snap-fit ​​block has a through hole, and a guide plate adapted to the through hole is fixed on the inner wall of the adjusting housing.

[0014] Furthermore, the gear ratio between the large gear and the small gear is 2:1.

[0015] The beneficial effects of this invention are:

[0016] By designing the support mechanism, to ensure that the rotation center of the workpiece coincides as much as possible with the rotation center of the lathe spindle during use, and to avoid uneven cutting depth and discrepancies between the machined diameter and the design value due to workpiece eccentricity, the two ends of the initially machined workpiece can be placed on the support frames of the two side support mechanisms respectively. Subsequently, because automotive parts are mostly irregular workpieces with different sizes in the two sections, the rotation center of the workpiece is tilted after being placed on the support frame. At this time, the workpiece is initially leveled by visually adjusting the height component. Then, the axis alignment component is used to locate the axis of the two sections of the workpiece. Then, a calibration rod is inserted between the two axis alignment components, and the tilt of the workpiece is determined by the levelness measuring device at the bottom of the calibration rod. Then, precise adjustment is made with the assistance of the levelness measuring device. After precise adjustment, the workpiece is fixed between the hydraulic chuck and the ejector pin, and the workpiece is rotated to match the tool head on the tool post for turning.

[0017] The height adjustment component is designed so that when adjusting the height, the rotating turntable drives the support shaft and drive gear to rotate. The drive gear drives the fixed rack and support column to move vertically. After the adjustment is completed, the turntable is pushed horizontally towards the support column. The end of the turntable is inserted horizontally into the embedded groove on the outer surface of the support column and engages with the locking plate to lock and fix the support column.

[0018] Through the design of the axial alignment component, during use, pushing the measuring plate upward causes the clamping end of the measuring plate to press down on the top of the workpiece. The measuring plate slides upward within the holes on the slide plate. At this time, the sliding block on the side of the measuring plate abuts against the bottom of the slide plate. As the measuring plate rises, the second traction rope is continuously pulled, which in turn drives the second side rack to move upward inside the measuring plate. The movement of the second side rack will drive the first side rack to move upward through the small gear and the large gear. Because the gear ratio of the large gear and the small gear is 2:1, the stroke of the first side rack is only half that of the second side rack. While the first side rack moves, it will pull the first traction rope at the bottom. The top of the first traction rope will pull the adjusting block. The adjusting block is subjected to force and descends in the receiving groove to squeeze the assembly module, pushing the two adjacent assembly modules to connect and fix them.

[0019] Through the modular design, the adjusting block gradually contacts several modules during its descent. The adjusting block first contacts the driving components on the modules, and the inclined surfaces of the docking groove and guide slope press against each other, causing the pushing end to move inside the adjusting housing. The pushing end then presses against the vertical slider two by pushing the inclined surface. The vertical slider two rises and simultaneously causes the top vertical plate to insert into the inclined groove at the bottom of the locking block. Again, guided by the inclined surface, the locking block moves and presses against the damping spring two. Subsequently, the adjusting block continues to descend along the outer surface of the modular assembly, pressing against the top inclined surface of the rotating block. Similarly, in… As the inclined plane is compressed and descends, the rotating block moves laterally and gradually disengages from the rotating hole on the inner wall of the receiving groove. The rotating block moves into the adjusting housing and pushes the horizontal slider to compress the inclined seat. The inclined seat pushes the vertical slider one and the locking part down. When the locking part is fully inserted into the adjusting housing below, the adjusting block disengages from the driving component. Under the action of the damping spring two and gravity, the vertical slider two and the inclined limiting block return to their original positions and descend. The inclined limiting block locks onto the outer surface of the horizontal slider near the rotating block to achieve locking and limiting of the horizontal slider. The driving component also returns to its original position and moves into the locking part, thus realizing the connection action of the upper and lower assembly modules.

[0020] By designing the baffle and travel limit block, after calibration, when the adjustment block shaft alignment assembly is stored, the baffle is first pulled out of the groove and fixed to the travel limit block. Then, the adjustment block is pressed down. At this time, the bottom of the baffle extending out of the adjustment block will be pressed together with the top of the slide plate. Then, the adjustment block pulls the first traction rope, which in turn pulls the first side rack, the second side rack, and the sliding block to reset and move, thus realizing the reset of the shaft alignment assembly.

[0042] 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.

[0043] Please see Figures 1-19This invention provides a technical solution for automotive parts turning equipment, including a lathe 1. The lathe used in this invention is a conventional lathe in the prior art, such as the CA6140A / CA6240A horizontal lathe produced by Shenyang No. 1 Lathe Factory, or the CA6150, CA6140, and CA6136 ordinary lathes produced by Shenyang Yiji General Lathe Co., Ltd. A hydraulic chuck 2 and a slide rail are provided on one side of the lathe 1. A center pin 3 and a tool post 6 are slidably connected on the slide rail. The tool post 6 is connected to a lead screw 4 and a feed rod 5. The lead screw 4 and the feed rod 5 are mounted on the lathe 1. The end of the lead screw 4 is connected to a motor inside the lathe 1. The top two... A blade 7, a coolant spray pipe 8, and a lighting lamp 9 are mounted on the side. The coolant spray pipe 8 is connected to the coolant outlet pipe, and the lighting lamp 9 is connected to a power source. A support mechanism 10 is slidably connected to the slide rail. A calibration rod 11 is inserted between the connecting blocks 26 of the two support mechanisms 10. A level measuring device is installed at the bottom of the calibration rod 11. The level measuring device is one of a bubble level, an electronic level, or a laser level. The support mechanism 10 includes a sliding seat 12 slidably connected to the slide rail. A support column 13 is vertically slidably connected to the middle of the sliding seat 12. The sliding seat 12 is provided with a height adjustment component adapted to the support column 13. The top of the support column 13... A support frame 20 is installed, and a slide plate 21 is laterally slidably connected to the bottom of the support frame 20. Both the support frame 20 and the slide plate 21 are threadedly connected to a tension knob. The end of the tension knob is provided with a damping block. The tension knob abuts and fixes the slide plate 21 and the measuring plate 22 through the damping block. The slide plate 21 is provided with a shaft alignment assembly. The shaft alignment assembly is made entirely of plastic material, which is low in cost and easy to install and replace. Through the design of the support mechanism 10, in order to ensure that the rotation center of the workpiece coincides as much as possible with the rotation center of the lathe spindle during use, and to avoid uneven cutting depth due to workpiece eccentricity, resulting in the diameter dimension after machining not matching the design value, the two ends of the initially machined workpiece can be placed on the two sides of the support. On the support frame 20 of the support mechanism 10, since most automotive parts are irregular workpieces with different sizes at both ends, the rotation center of the workpiece is tilted after being placed on the support frame 20. At this time, the workpiece is first initially leveled by the height adjustment component under visual conditions. Then, the axis alignment component is used to position the axis at both ends of the workpiece. Then, the calibration rod 11 is inserted between the two axis alignment components. The tilt of the workpiece is determined by the level measurement device at the bottom of the calibration rod 11. Then, the workpiece is precisely adjusted with the assistance of the level measurement device. After the precise adjustment, the workpiece is fixed between the hydraulic chuck 2 and the ejector pin 3, and the workpiece is rotated to match the cutter head 7 on the tool holder 6 for turning.

[0044] See Figure 4The height adjustment assembly includes an embedded groove on one side of the support column 13 and a support shaft 15 movably connected to the sliding seat 12. One end of the support shaft 15 movably extends through to the outside of the sliding seat 12 and is fixedly connected to the turntable 14. The other end of the support shaft 15 extends through to the inner and outer surfaces of the embedded groove, where two slide bars are symmetrically fixed. A drive gear 16 is slidably sleeved on the outside of the slide bars. The drive gear 16 is rotatably connected within the embedded groove. A fixed rack 17 that meshes with the drive gear 16 is fixed on one inner wall of the embedded groove. Several slots 18 are circumferentially formed at the center of the end of the support shaft 15. Several card plates 19, which are adapted to the card slots 18, are fixed vertically at equal intervals on the wall. Since automotive parts have fixed sizes for several batches, the card plates 19 only need to be installed according to their dimensions to ensure that they correspond to the card slots 18. Through the design of the height adjustment component, when adjusting the height, the rotating turntable 14 drives the support shaft 15 and the drive gear 16 to rotate. The drive gear 16 drives the fixed rack 17 and the support column 13 to move vertically. After the adjustment is completed, the turntable 14 is pushed horizontally towards the support column 13. The end of the turntable 14 is inserted horizontally into the embedded groove on the outer surface of the support column 13 and engages with the card plates 19 to lock and fix the support column 13.

[0045] See Figures 5-9The axis alignment assembly includes a measuring plate 22, which is vertically slidably connected to the end of the slide plate 21. A receiving groove 23 is formed on one outer surface of the measuring plate 22. Several assembly modules are provided on the inner wall of the receiving groove 23.

A traction rope 32 and a traction rope 33 are respectively connected to the bottom of the first side rack 27 and the top of the second side rack 28. The top of the second traction rope 33 extends to the top of the measuring plate 22. The outer side is connected to the sliding block 36, which is slidably connected to the slide rail 35 on the outer surface of the measuring plate 22. The end of the traction rope 32 is fixedly connected to the connecting end of the adjusting block 34. The adjusting block 34 is vertically slidably connected in the receiving groove 23. An movable opening adapted to the connecting end is provided between the receiving groove 23 and the receiving cavity 24. Guide wheels are provided at the bends of the traction rope 32 and the traction rope 33, which can reduce wear and ensure that the movement trajectory of the two does not change. Through the design of the height adjustment component, when adjusting the height, the rotating turntable 14 drives the support shaft 15 and the drive gear 16 to rotate. The drive gear 16 drives the fixed rack 17 and the support column 13 to move vertically. After the adjustment is completed, the turntable 14 is pushed horizontally towards the support column 13. The end of the turntable 14 is inserted horizontally into the embedded groove on the outer surface of the support column 13 and is engaged with the locking plate 19 to lock and fix the support column 13.

[0046] See Figures 10-17The assembly module includes an adjustment housing 25. A positioning block 37 is fixed to the top of each of the two sides of the outer surface of the adjustment housing 25. A horizontal slider 38 is slidably connected to each of the two sides of the interior of the adjustment housing 25. A rotating block 39 is fixed at the center of the side of each horizontal slider 38. The rotating block 39 extends through the outer side of the adjustment housing 25 into a rotating hole. The rotating hole is located within the receiving groove 23. A top inclined surface 40 is formed on the outer surface of the rotating block 39 at one end inside the receiving groove 23. Vertical... The vertical slider 41 and the vertical slider 46 are connected. The bottom of the vertical slider 46 is fixed with a sloping limiting block 47 that matches the horizontal slider 38. The top of the vertical slider 46 is fixed with a vertical plate 48. The top center of the vertical slider 41 has a sloping seat 42 that matches the horizontal slider 38. The bottom center of the vertical slider 41 has a locking part 43. The top and bottom centers of the adjusting housing 25 both have top and bottom insertion holes that match the locking part 43. The bottom of the locking part 43 has a locking groove 44. The bottom side of the vertical slider 41... A damping spring 45 is connected between the edge and the bottom of the adjusting housing 25. A locking block 49 is laterally slidably connected to the top of the adjusting housing 25 on both sides of the top insertion hole. The locking block 49 has a through hole 50. A guide plate 51 adapted to the through hole 50 is fixed on the inner wall of the adjusting housing 25. The locking end of the locking block 49 is locked and adapted to the locking groove 44. A damping spring 52 is connected between the other side of the locking block 49 and the inner wall of the adjusting housing 25. A sloped groove 53 is formed at the bottom of the locking block 49, and a through-hole extending to the top of the sloped groove 53 is formed at the top. The top of the groove 53 has a perforation 54; the assembly module also includes a driving component 55, which includes a push end 56 and a drive end 57 fixedly connected. The drive end 57 is located on the outside of the adjustment housing 25. Guide slopes 60 are provided on both sides of the outer surface of the drive end 57. The push end 56 is movably inserted into the adjustment housing 25. A clamping groove 58 is provided at the center of the end of the push end 56. A push slope 59 is provided at the bottom of the clamping groove 58. The bottom of the push slope 59 abuts against the bottom of the vertical slider 46. A travel limit plate 61 is also fixed on the side of the push end 56.Through the design of the assembly modules, the adjusting block 34 will gradually contact several assembly modules during its descent. The adjusting block 34 will first contact the driving component 55 on the assembly module. Through the inclined surface compression of the docking groove 63 and the guide inclined surface 60, the pushing end 56 will move inside the adjusting housing 25. The pushing end 56 will press the vertical slider 46 through the pushing inclined surface 59. The vertical slider 46 will rise and simultaneously drive the top vertical plate 48 to insert into the inclined groove 53 at the bottom of the locking block 49. Similarly, through the compression and guidance of the inclined surface, the locking block 49 will move and compress the damping spring 52. Subsequently, the adjusting block 34 will continue to descend along the outer surface of the assembly module. The adjusting block 34 will press the top inclined surface 40 on the outer surface of the rotating block 39. As the pressure decreases, the rotating block 39 moves laterally and gradually disengages from the rotating hole on the inner wall of the receiving groove 23. The rotating block 39 moves into the adjusting housing 25 to be housed and pushes the horizontal slider 38 to press against the inclined seat 42. The inclined seat 42 houses and pushes the vertical slider 41 and the locking part 43 downward. When the locking part 43 is fully inserted into the adjusting housing 25 below, the adjusting block 34 disengages from the driving member 55. Under the action of the damping spring 52 and gravity, the vertical slider 46 and the inclined limiting block 47 return to their original position and descend. The inclined limiting block 47 locks onto the outer surface of the horizontal slider 38 near the rotating block 39 to lock and limit the horizontal slider 38. The driving member 55 also returns to its original position and locks into the locking part 43, thus realizing the connection action of the upper and lower assembly modules.

[0047] See Figures 18-19 The adjusting block 34 has symmetrically formed positioning grooves 62 on its two inner walls that are adapted to the positioning block 37. The adjusting block 34 also has symmetrically formed docking grooves 63 on its inner wall in the middle that are adapted to the guide slope 60. The adjusting block 34 has symmetrically formed grooves 64 on its outer surface. A baffle 65 is rotatably connected inside the groove 64. A travel limiting block 66 adapted to the baffle 65 is fixed to the top of the opening of the groove 64. The design of the baffle 65 and the travel limiting block 66... Therefore, after calibration, when the axis alignment assembly of the adjusting block 34 is stored, the baffle 65 is first pulled out from the groove 64, and the baffle 65 is fixed to the travel limit block 66. Then, the adjusting block 34 is pressed down. At this time, the bottom of the baffle 65 extending out of the adjusting block 34 will be pressed together with the top of the slide plate 21. Then, the adjusting block 34 pulls the traction rope 32, and the traction rope 32 pulls the side rack 27, the side rack 28 and the sliding block 36 to reset and move, thus realizing the reset of the axis alignment assembly.

[0048] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0049] During use, to ensure that the rotation center of the workpiece coincides as much as possible with the rotation center of the lathe spindle, and to avoid uneven cutting depth and discrepancies between the machined diameter and the design value due to workpiece eccentricity, the two ends of the initially machined workpiece can be placed on the support frames 20 of the two side support mechanisms 10. Since automotive parts are mostly irregularly shaped and of different sizes, the rotation center of the workpiece will be tilted after being placed on the support frames 20. At this point, the workpiece should be initially leveled visually using the height adjustment component, and then aligned using the spindle alignment. The components position the axes of the two sections of the workpiece. Then, a calibration rod 11 is inserted between the two axis alignment components. The inclination of the workpiece is determined by the level measuring device at the bottom of the calibration rod 11. Subsequently, precise adjustment is performed with the assistance of the level measuring device. After precise adjustment, the workpiece is fixed between the hydraulic chuck 2 and the ejector pin 3, and the workpiece is rotated to match the cutter head 7 on the tool holder 6 for turning. The operation process of the height adjustment component is as follows: When adjusting the height, the support shaft 15 and the drive gear 16 are rotated by rotating the turntable 14. The drive gear 16 drives... The fixed rack 17 and support column 13 move vertically. After adjustment, the turntable 14 is pushed laterally towards the support column 13. The end of the turntable 14 is inserted laterally into the inner groove on the outer surface of the support column 13 and engages with the clamping plate 19 to lock and fix the support column 13. The operation process of the axis alignment assembly is as follows: When in use, push the measuring plate 22 upward so that the clamping end of the measuring plate 22 presses down on the top of the workpiece. The measuring plate 22 slides upward in the hole on the slide plate 21. At this time, the sliding block 36 on the side of the measuring plate 22 abuts against the bottom of the slide plate 21. As the measuring plate 22 moves, the measuring plate 22 slides upward in the hole on the slide plate 21. As the measuring plate 22 rises, the second traction rope 33 is continuously pulled, which in turn drives the second side rack 28 to move upward inside the measuring plate 22. The movement of the second side rack 28 will drive the first side rack 27 to move upward through the small gear 31 and the large gear 30. Because the gear ratio of the large gear 30 and the small gear 31 is 2:1, the stroke of the first side rack 27 is only half that of the second side rack 28. While the first side rack 27 moves, it will pull the first traction rope 32 at the bottom. The top of the first traction rope 32 will pull the adjusting block 34, and the adjusting block 34 will descend within the receiving groove 23 under force.During its descent, the adjusting block 34 gradually contacts several assembly modules. First, it contacts the drive component 55 on the assembly module. Through the pressure of the inclined groove 63 and the guide inclined surface 60, the pushing end 56 moves inside the adjusting housing 25. The pushing end 56 then presses against the vertical slider 46 via the pushing inclined surface 59. The vertical slider 46 retracts and rises, simultaneously causing the top vertical plate 48 to insert into the inclined groove 53 at the bottom of the locking block 49. Similarly, guided by the pressure of the inclined surface, the locking block 49 moves and presses against the damping spring 52. Subsequently, the adjusting block 34... As segment 34 continues to descend along the outer surface of the assembly module, adjusting block 34 presses against the top inclined surface 40 of the outer surface of rotating block 39. Similarly, under the pressure of the inclined surface, rotating block 39 moves laterally and gradually disengages from the rotating hole on the inner wall of the receiving groove 23. Rotating block 39 moves into the adjusting housing 25 for storage and pushes the horizontal slider 38 to press against the inclined seat 42. The inclined seat 42 then pushes the vertical slider 41 and the locking part 43 downwards. When the locking part 43 is fully inserted into the lower adjusting housing 25, adjusting block 34 disengages from the driving member 55, under the influence of damping spring 52 and gravity. Under the action of the vertical slider 46 and the inclined plane limiting block 47, the vertical slider 46 and the inclined plane limiting block 47 are reset and descend. The inclined plane limiting block 47 is engaged with the outer surface of the horizontal slider 38 near the rotating block 39 to achieve the engagement and limiting of the horizontal slider 38. The driving component 55 is also reset and moved into the engagement part 43, thus realizing the connection action of the upper and lower assembly modules. When the engagement end of the measuring plate 22 is pressed down on the top of the workpiece, the stroke of the measuring plate 22 is the diameter of the bow and arrow, while the pulling stroke of the adjusting block 34 is the radius of the workpiece. Moreover, the assembly modules within the pulling stroke have been connected into a whole. A radius marker is formed. Then, the radius marker is pulled outwards, and a calibration rod 11 is connected between the two ends of the radius marker. The height of the two support mechanisms 10 can be adjusted using the leveling device at the bottom of the calibration rod 11 to achieve the effect of calibrating the shaft center. The connecting block 26 has a slot and a locking block. These slot and locking block are respectively adapted to the top insertion hole on the outer surface of the adjusting housing 25 and the positioning block 37. Therefore, the connecting block 26 can be installed at the end of the adjusting housing 25 or on the side outer surface of the adjusting housing 25, thus adapting to workpieces of various sizes.
