A sleeve boring device for metal product processing

Abstract

The present invention relates to the field of metal processing, and in particular to a sleeve boring device for processing metal products. Due to the lack of targeted cleaning means, the existing metal sleeve boring device is difficult to quickly remove debris during processing, and it is easy to cause repeated friction in the processing area as the tool continues to rotate, which aggravates the wear of the boring tool and easily leads to uneven contact between the tool and the metal sleeve, and the roughness increases, which greatly damages the boring accuracy and smoothness, resulting in poor boring accuracy of the finished metal sleeve. A sleeve boring device for processing metal products includes a base, a control module and a support frame; one side of the base is fixedly connected to the control module, and the base is fixedly connected to the support frame. The boring tool is first limited by a clamping block, and the fixed frame then constrains the moving sleeve rod. The boring tool is limited by the moving sleeve rod for a second time. Under the double limit, the boring tool is stabilized, so that the inner side of the metal sleeve can be processed smoothly in the subsequent process.

Description

Technical Field

[0001] The invention relates to the field of metal processing, in particular to a sleeve boring device for processing metal products. Background Art

[0002] In modern industrial manufacturing processes, metal sleeves are key basic components of various mechanical equipment, and strict requirements are placed on their processing accuracy and quality. However, traditional metal sleeve boring devices have limitations in many key links, among which the problem of cleaning metal debris is particularly prominent.

[0003] Metal debris cleaning has always been the shortcoming of traditional boring devices. As the boring operation progresses, metal debris is continuously generated and accumulated on the lower inner side of the metal sleeve. Due to the lack of targeted cleaning methods in existing metal sleeve boring devices, the debris is difficult to remove quickly during processing, and it is easy for the debris to be repeatedly rubbed in the processing area as the tool continues to rotate, which aggravates the wear of the boring tool and shortens the tool life. It is also easy to cause the contact area between the tool and the metal sleeve to be uneven and the roughness to increase, which greatly damages the boring accuracy and smoothness, resulting in poor boring accuracy of the finished metal sleeve. Summary of the invention

[0004] In order to overcome the above shortcomings, the present invention provides a sleeve boring device for metal product processing, which can not only efficiently dissipate heat and cool the boring tool, but also clean up debris in time, thereby improving the boring accuracy and smoothness of the contact part between the boring tool and the metal sleeve.

[0008] Further explanation, the tool clamping part includes a movable sleeve rod, which is slidably connected to the fixed frame, and a fixed plate is fixedly connected to the movable sleeve rod. A tool groove is opened at one end of the movable sleeve rod, and a boring tool is slidably connected to the tool groove of the movable sleeve rod. An octagonal nut is fixedly connected to the fixed plate, and a locking screw is threadedly connected to the octagonal nut. A clamping block is rotatably connected to the lower part of the locking screw, and the clamping block is clamped in the limiting groove of the boring tool. A fixing bolt is fixedly connected to the middle part of the movable sleeve rod.

[0009] It is further explained that the limiting groove of the boring tool is a square concave surface.

[0010] Further description, the cooling part includes a water inlet pipe, which is fixedly connected to the fixed support rod, one end of the water inlet pipe is fixedly connected to a fixed ring, a hollow ring is rotatably connected to the fixed ring, one side of the hollow ring is fixed and connected to an extension pipe, an extension plate is fixedly connected to the bottom of the movable sleeve rod, a nozzle is fixedly connected to the upper part of the extension plate, and a rubber hose is connected between the nozzle and one end of the extension pipe through a clamp.

[0011] Further description, it also includes a booster, which is arranged on the fixed frame, and is used to increase the impact force of the coolant. The booster includes a convex ring, and the end of the fixed support rod away from the support frame is fixedly connected to the convex ring, and one side of the fixed frame is slidably connected to a movable inclined plane rod, one end of the movable inclined plane rod contacts the outer surface of the convex ring, and a reset spring is connected between the movable inclined plane rod and the fixed frame, and one side of the fixed frame is slidably connected to a lifting plate, and one side of the fixed plate is slidably connected to a lifting frame, and the middle part of the lifting frame is rotatably connected to a rotating ring, and compression springs are connected between the lifting frame and the fixed frame on both sides, and the upper part of the extension plate is fixedly connected to a limiting cover, and the end of the lifting plate close to the nozzle is fixedly connected to two guide rods, and the two guide rods are both slidably connected to the limiting cover, and extrusion springs are respectively connected between the two guide rods and the limiting cover.

[0012] The beneficial effects of the present invention are as follows: 1. The three clamping seats clamp the metal sleeve at the same time, which effectively prevents the subsequent displacement of the metal sleeve and ensures the boring quality of the metal sleeve. The boring tool is first limited by the clamping block, and the fixed frame then constrains the moving sleeve rod. The boring tool is limited for the second time by the moving sleeve rod. Under the double limitation, the boring tool is stabilized, so that the inner side of the metal sleeve can be processed smoothly subsequently.

[0013] 2. The boring tool performs a boring operation on the inner surface of the metal sleeve along the inner ring of the metal sleeve in a forward rotation manner, and then bores the inner side surface of the metal sleeve, so that the inner side surface of the metal sleeve gradually transforms from a rough initial state to a smooth and flat state.

[0014] 3. The coolant covers the contact area between the inner side of the metal sleeve and the boring tool. The coolant quickly wraps the boring tool, takes away the heat of the boring tool, cools down the boring tool in time, and ensures that it is always in a stable and efficient working state.

[0015] 4. The telescopic rod of the electric push rod will slowly pull the moving plate, causing the moving plate to retract. When the moving plate retracts, it will further drive the octagonal rod and the moving slot plate to retract together. The oblique groove on the moving slot plate pushes the fixing bolt, the moving sleeve rod, the boring tool and the extension plate to move along the guide of the fixed frame. During this process, the boring tool rotates and fits along the inner ring inclined surface of the metal sleeve, thereby boring the inner ring of the metal sleeve. The boring process can be completed on different inner diameter parts of the metal sleeve, so that the boring tool can bore the metal sleeve more comprehensively.

[0016] 5. The lifting plate moves upward, squeezing one end of the rubber hose close to the nozzle. As the rubber hose is squeezed, the pipe of the rubber hose gradually shrinks and deforms, the internal space shrinks, the pipe diameter becomes smaller, and the liquid pressure inside the rubber hose rises sharply, so that the impact force of the coolant ejected from the nozzle is also increased, so that the metal debris accumulated in the lower part of the inner side of the metal sleeve can be quickly and thoroughly washed away, making the contact part between the boring tool and the metal sleeve smooth and smooth, so that the accuracy and fluency of the boring between the boring tool and the metal sleeve are improved.

[0033] The boring part includes an octagonal rod 51, which is rotatably connected to the fixed support rod 3. A ring groove is opened on one side of the octagonal rod 51, and a movable plate 52 is sleeved on the ring groove of the octagonal rod 51. The lower part of the movable plate 52 is slidably connected to the support frame 2. An electric push rod 53 is fixedly connected to the middle part of the support frame 2. One end of the telescopic rod of the electric push rod 53 is welded to the movable plate 52. A servo motor 54 is fixedly connected to the upper part of the support frame 2. A pinion 55 is fixedly connected to the output shaft of the servo motor 54. An annular rod 56 is slidably connected to the octagonal rod 51. One end of the annular rod 56 is fixedly connected to a fixed gear 57. The pinion 55 meshes with the fixed gear 57. A fixed frame 58 is welded to the end of the annular rod 56 away from the fixed gear 57. The end of the octagonal rod 51 away from the movable plate 52 is fixedly connected to a movable groove plate 59, and an oblique groove is opened on the movable groove plate 59.

[0034] The tool clamping part includes a movable sleeve rod 61, which is slidably connected to the fixed frame 58, and a fixed plate 62 is fixedly connected to the movable sleeve rod 61. A tool groove is opened at one end of the movable sleeve rod 61, and a boring tool 63 is slidably connected to the tool groove of the movable sleeve rod 61. The surface of the boring tool 63 has a limiting groove, an octagonal nut 64 is welded to the fixed plate 62, and a locking screw 65 is threadedly connected to the octagonal nut 64. A clamping block 66 is rotatably connected to the lower part of the locking screw 65, and the clamping block 66 is clamped in the limiting groove of the boring tool 63. A fixing bolt 67 is welded to the middle part of the movable sleeve rod 61, and the fixing bolt 67 is located in the oblique groove of the movable groove plate 59.

[0035] The limiting groove of the boring tool 63 is a square concave surface.

[0036] The cooling part includes a water inlet pipe 71, which is fixedly connected to the fixed support rod 3. One end of the water inlet pipe 71 is fixedly connected to a fixed ring 72. A hollow ring 73 is rotatably connected to the fixed ring 72. The side of the hollow ring 73 away from the fixed ring 72 is fixed and connected to an extension pipe 74. An extension plate 75 is fixedly connected to the bottom of the movable sleeve rod 61. A nozzle 76 is fixedly connected to the upper part of the extension plate 75. A rubber hose 77 is connected between the nozzle 76 and one end of the extension pipe 74 away from the servo motor 54 through a clamp.

[0037] When the metal sleeve 44 needs to be bored, the staff first puts the metal sleeve 44 between the three clamping seats 43, and then uses an octagonal wrench to tighten the three octagonal bolts 42 in turn. The bolts drive the clamping seat 43 to move toward the metal sleeve 44 through the threads on the movable seat 41. The three clamping seats 43 clamp the metal sleeve 44 at the same time, which effectively prevents the subsequent displacement of the metal sleeve 44 and ensures the boring quality of the metal sleeve 44. Then, the boring tool 63 is inserted into the tool groove of the movable sleeve rod 61, and the octagonal wrench is used to rotate the locking screw 65 again. The locking screw 65 drives the clamping block 66 to move downward along the threads on the octagonal nut 64, and the clamping block 66 is clamped into the limiting groove on the surface of the boring tool 63. The boring tool 63 is limited by the clamping block 66 first, and the fixing frame 58 then constrains the movable sleeve rod 61, and the movable sleeve rod 61 limits the boring tool 63 for the second time. Under the double limit, the boring tool 63 is stabilized, so that the inner side of the metal sleeve 44 can be processed smoothly later. Then the staff connects the external coolant input pipe to one end of the water inlet pipe 71, and finally the staff starts the servo motor 54, the control module 11, the hydraulic cylinder body 45, the external coolant pump and the electric push rod 53. The output shaft of the servo motor 54 drives the pinion 55 to reverse, and the pinion 55 reverses to drive the fixed gear 57, the annular rod 56 and the octagonal rod 51 to rotate forward together. The forward rotation of the annular rod 56 drives the movable slot plate 59 to rotate forward, and the forward rotation of the annular rod 56 drives the fixed frame 58, the movable sleeve rod 61, the boring tool 63 and the extension plate 75 together In forward rotation, the control module 11 controls the push rod of the hydraulic cylinder 45 to start to retract. The retraction of the push rod of the hydraulic cylinder 45 drives the moving seat 41, the three octagonal bolts 42, the three clamping seats 43 and the metal sleeve 44 to move together in the direction of the boring tool 63. Since the fixed frame 58 and the boring tool 63 are in an in-situ rotating state, the inner ring of the metal sleeve 44 will contact the boring tool 63 at this time. In this state, the boring tool 63 boring operation is performed on the inner surface of the metal sleeve 44 along the inner ring of the metal sleeve 44 in a forward rotation manner, and then the inner side surface of the metal sleeve 44 is bored, so that the inner side surface of the metal sleeve 44 gradually transforms from a rough initial state to a smooth and flat state. The external coolant pump is running, driving the coolant to flow to the water inlet pipe 71. Then it flows into the hollow ring 73 along the pipeline. Inside the hollow ring 73, the coolant continues to flow, and then it is injected into the extension pipe 74, and then it flows smoothly along the rubber hose 77. Finally, the nozzle 76 sprays out the coolant delivered by the rubber hose 77. The coolant covers the contact part between the inner side of the metal sleeve 44 and the boring tool 63. The coolant quickly wraps the boring tool 63 and takes away the heat of the boring tool 63. The boring tool 63 is cooled in time to ensure that it is always in a stable and efficient working state. As time goes by, after the metal sleeve 44 is bored to a certain position, the control module 11 is started and controls the telescopic rod of the electric push rod 53 to retract. During the retraction process, the telescopic rod of the electric push rod 53 slowly pulls the moving plate 52, causing the moving plate 52 to retract accordingly.When the movable plate 52 retracts, it will further drive the octagonal rod 51 and the movable slot plate 59 to retract together. The oblique slot on the movable slot plate 59 pushes the fixing bolt 67, the movable sleeve rod 61, the boring tool 63 and the extension plate 75 to move along the guide of the fixed frame 58. In this process, the boring tool 63 rotates and fits along the inner ring inclined surface of the metal sleeve 44, so as to carry out a boring operation on the inner ring of the metal sleeve 44, and can complete the boring process on different inner diameter parts of the metal sleeve 44, so that the boring tool 63 can bore the metal sleeve 44 more comprehensively. Finally, the staff turns off the servo motor 54, the control module 11, the hydraulic cylinder body 45, the external coolant pump and the electric push rod 53, and the control module 11 is closed, the push rod of the hydraulic cylinder 45 and the telescopic rod of the electric push rod 53 remain in a stopped state, the external coolant pump no longer pumps coolant into the water inlet pipe 71, the staff uses an octagonal wrench to rotate the locking screw 65 to reset, the clamping block 66 is reset and no longer clamps the boring tool 63, the staff removes the boring tool 63 from the tool slot of the movable sleeve rod 61, and uses an octagonal wrench to rotate the octagonal bolt 42 in turn, the three clamping seats 43 are reset and no longer clamp the metal sleeve 44, the staff removes the bored metal sleeve 44, and finally the staff starts the servo motor 54, the control module 11, the hydraulic cylinder 45 and the electric push rod 53 to reset, and the movable seat 41 and the movable sleeve rod 61 are reset.

[0038] Embodiment 2: Based on embodiment 1, Fig.11 and Fig.12 As shown, a booster is also included, which is arranged on the fixed frame 58. The booster is used to increase the impact force of the coolant. The booster includes a convex ring 81. The convex ring 81 is welded to the end of the fixed support rod 3 away from the support frame 2. A moving inclined rod 82 is slidably connected to one side of the fixed frame 58. One end of the moving inclined rod 82 contacts the outer surface of the convex ring 81. A return spring 821 is connected between the moving inclined rod 82 and the fixed frame 58. A lifting plate 81 is slidably connected to one side of the fixed frame 58. 3. A lifting frame 84 is slidably connected to one side of the fixed plate 62, a rotating ring 85 is rotatably connected to the middle of the lifting frame 84, compression springs 86 are connected between both sides of the lifting frame 84 and the fixed frame 58, a limit cover 87 is fixedly connected to the upper part of the extension plate 75, and two guide rods 88 are fixedly connected to one end of the lifting plate 83 close to the nozzle 76, and the two guide rods 88 are slidably connected to the limit cover 87, and extrusion springs 89 are connected between the two guide rods 88 and the limit cover 87 respectively.

[0039] Since the fixed support rod 3 and the convex ring 81 are fixed, under the action of the return spring 821, the movable inclined rod 82 is fitted with the outer side of the convex ring 81, and the fixed frame 58 rotates forward to drive the movable inclined rod 82, the lifting plate 83, the lifting frame 84 and the rotating ring 85 to rotate together. When the movable inclined rod 82 rotates to the lower part of the convex ring 81, the convex ring 81 squeezes the movable inclined rod 82 to move, the return spring 821 is compressed, and the movable inclined rod 82 moves through the inclined surface on the movable inclined rod 82 to push the lifting frame 84 and the rotating ring 85 along the fixed frame 5 8 moves upward, the rotating ring 85 moves upward to push the lifting plate 83 and the two guide rods 88 to move upward under the guidance of the limit cover 87 and the fixing frame 58, the two extrusion springs 89 are compressed, and under the limit of the limit cover 87, the lifting plate 83 moves upward to squeeze the end of the rubber hose 77 close to the nozzle 76. With the squeezing of the rubber hose 77, the pipe of the rubber hose 77 gradually shrinks and deforms, the internal space is reduced, the pipe diameter becomes smaller, and the liquid pressure in the rubber hose 77 rises sharply, so that the coolant ejected from the nozzle 76 is ejected. The impact force is also improved, so that the metal debris accumulated in the lower part of the inner side of the metal sleeve 44 can be quickly and thoroughly washed away, so that the contact part between the boring tool 63 and the metal sleeve 44 is smooth and flat, so that the boring accuracy and fluency of the boring tool 63 and the metal sleeve 44 are improved. When the extension plate 75 moves, it drives the limit cover 87, the two guide rods 88 and the lifting plate 83 to move. The movement of the lifting plate 83 drives the rotating ring 85 to rotate on the lifting frame 84 through the friction force. When the moving inclined rod 82 continues to rotate to the upper part of the convex ring 81, the reset spring 82 1, the movable inclined rod 82 is reset, the movable inclined rod 82 is reset and no longer squeezes the lifting frame 84 and the rotating ring 85, the lifting frame 84 and the rotating ring 85 are reset under the action of the two compression springs 86, the rotating ring 85 is reset and no longer pushes the lifting plate 83, the lifting plate 83 is reset under the action of the two squeezing springs 89. When the lifting plate 83 stops squeezing the rubber hose 77, thanks to the elastic properties of the rubber hose 77 itself and the help of the continuously flowing coolant, the originally compressed and narrowed pipe diameter recovers autonomously and gradually returns to the initial state.
