Description

Technical Field

[0001] The present invention relates to the technical field of pin extraction, and particularly relates to a fully automatic and efficient pin extraction device. Background Art

[0002] The extraction of pins often encounters difficulties due to rust, interference fit or deformation. Traditional methods mostly use a screw rod to connect with the pin, and repeatedly knock the baffle upwards through an impact sleeve to generate an upward impact on the screw rod to pull out the pin. It relies on manual hammering to pull out the pin. The operation process lacks the coordination of automatic lubrication and vibration, and is prone to secondary jamming due to frictional resistance.

[0003] Existing pin extraction devices rely on manual impact or pulling actions, resulting in low efficiency and easy damage to components. Especially in high-strength and rust situations, it is difficult to achieve efficient and non-destructive pin extraction. Summary of the Invention

The knocking member includes a knocking part, and the knocking part is arranged outside the servo motor 15 and extends below the impact sleeve 8.

[0020] Specifically, the telescopic end of the electric rod 11 is connected with a connecting plate 12 through a connecting component and a fixing component, and the lower part of the connecting plate 12 is welded to the upper end of the telescopic plate 13.

[0021] A rubber pad is arranged below the supporting leg 14. The supporting leg 14 can be placed at the working place in cooperation with the rubber pad and provide support for the telescopic plate 13. The telescopic plate 13 can extend under the action of an external force, can contract under the action of gravity, and can provide support for the connecting plate 12. Through the connecting plate 12, support is provided for the electric rod 11 and the support plate 10, so that the support plate 10 can support the connecting sleeve 9. The connecting sleeve 9 can provide a rotational support for the T-bar 2 through a bearing, so that the T-bar 2 provides support for the guide rod 1 and the connecting cylinder 3. The guide rod 1 can provide support for the blocking disc 7. The longitudinal rod 4 can provide support for the inserting rod 5, and the inserting rod 5 can provide support for the screw rod 6 through a threaded action. The screw rod 6 can be threadedly connected to the upper end of the pin through a threaded action. The guide rod 1 can provide a moving guiding function for the impact sleeve 8, while the T-bar 2 can provide a resisting limit for the impact sleeve 8. The blocking disc 7 can bear the impact and transmit the impact force to the guide rod 1, the T-bar 2, the longitudinal rod 4, the inserting rod 5 and the screw rod 6. The support plate 10 can provide support for the servo motor 15. The servo motor 15 can drive the inclined rubber wheel 16 to rotate by using the driving end. The inclined rubber wheel 16 can use the inclined surface and the rotational power to push the inclined wheel 17 to rotate. The inclined wheel 17 will drive the T-bar 2 to rotate around the bearing as the center under the support of the connecting cylinder 3.

[0022] In the actual application process of this embodiment: The staff can control the electric rod 11 to extend according to the actual needs, so that the electric rod 11 drives the connecting plate 12, the telescopic plate 13 and the supporting feet 14 to translate away from the connecting sleeve 9 together under the support of the supporting plate 10 through the connecting components and the fixing components, thereby realizing the function of adjusting the gap between the multiple supporting feet 14, making it convenient for the supporting feet 14 to be placed at various working locations. The staff can move the taking-out device according to the actual needs, so that the screw rod 6, the inserting rod 5 and the sleeve 18 can be inserted into the hole where the pin to be taken out is located, and the supporting feet 14 are supported at the working location, so that the connecting sleeve 9 can support the T-bar 2 to keep it vertical. Subsequently, the staff needs to control the servo motor 15 to start, so that it drives the inclined rubber wheel 16 to rotate by using the driving end. The inclined rubber wheel 16 will then drive the inclined wheel 17 to rotate by using the frictional force. The inclined wheel 17 will drive the connecting cylinder 3, the T-bar 2, the one-way valve 50, the longitudinal rod 4, the inserting rod 5 and the screw rod 6 to rotate together by using the rotational power, so that the screw rod 6 is threadedly connected to the pin by using the gravity and rotational power of the components above it. At the same time, the longitudinal rod 4 will drive the sleeve 18 to rotate together by using the rotational power through the guide block 20.

[0023] The staff can drive the threaded ring 22 to rotate by using the abutting cylinder 21 according to the size requirement of the pin, so that the threaded ring 22 is threadedly separated from the sleeve 18. Subsequently, the screw rod 6 is separated from the inserting rod 5 by using the thread action, and the screw rod 6 and the abutting cylinder 21 with appropriate sizes for the pin are replaced according to the needs.

[0024] As a preferred embodiment of the present invention, the pushing member includes: The sleeve 18 is sleeved on the outside of the longitudinal rod 4 and the inserting rod 5, and is connected to the longitudinal rod 4 through a guiding member; The abutting cylinder 21 is threadedly connected to the lower end of the sleeve 18 and is located outside the screw rod 6; The pressing plate 24 is fixedly connected to one side of the lower cylinder through a connecting member; The push rods 25 are symmetrically fixed on the pressing plate 24, and the ends are arc-shaped.

[0025] Specifically, guide grooves 19 are symmetrically formed on the inner side of the sleeve 18. Guide blocks 20 are symmetrically welded on the outside of the longitudinal rod 4, and the guide blocks 20 extend into the inner side of the guide grooves 19 to provide moving guidance for the sleeve 18 and support the guide cylinder. A threaded ring 22 is welded to the upper end of the abutting cylinder 21, and the threaded ring 22 is threadedly connected to the lower end of the sleeve 18. The sleeve 18 can provide support for the abutting cylinder 21 by using the thread action. A side plate 23 is fixed on the outside of the sleeve 18, and the side plate 23 is welded to the pressing plate 24. The side plate 23 can provide support for the pressing plate 24 through the sleeve 18, so that the pressing plate 24 stably supports the push rods 25, and the push rods 25 can push the push ring 27 by using an external force.

[0026] The knocking member includes: The movable port 26 runs through the inclined rubber wheel 16 and is opened in a ring shape. The annular groove 29 is opened in the inclined rubber wheel 16, runs through the outer side of the inclined rubber wheel 16, and communicates with the movable port 26. The pushing and connecting part runs through the movable port 26. The magnetic pushing part is arranged in the inclined rubber wheel 16 and is located outside the inclined wheel 17.

[0027] Specifically, the inclined rubber wheel 16 can provide a space for opening the movable port 26 and the annular groove 29. The movable port 26 can provide a moving space for the pushing ring 27 and the support rod 28. The push rod 25 can use the arc-shaped end to provide a rotational support for the pushing ring 27.

[0028] The pushing and connecting part includes: The pushing ring 27 is movably arranged on the inner side of the movable port 26 and has a curvature on the outer side. There are multiple support rods 28, which are evenly and symmetrically welded on the pushing ring 27 and run through the upper end of the movable port 26. The connecting rod 35 is welded on the support rod 28. The supporting block 36 is welded on the connecting rod 35. The plug 37 is fixed on the supporting block 36.

[0029] Specifically, the pushing ring 27 can use an external force to push the support rod 28 and the connecting rod 35 upward, so that the connecting rod 35 drives the supporting block 36 and the plug 37 to move upward together.

[0030] The magnetic pushing part includes: There are multiple T-grooves 31, which are opened in the inclined rubber wheel 16 and communicate with the annular groove 29. There are multiple inclined arc plates 30, which are evenly distributed in a ring shape on the inner side of the annular groove 29. The two ends are inclined surfaces and are guidingly connected to the T-grooves 31, and the end close to the movable port 26 extends into the movable port 26. The magnet 33 is fixed at the end of the inclined arc plate 30 far from the movable port 26. The magnetic ring 34 is embedded on the outer side of the inclined wheel 17 and corresponds to the position of the magnet 33.

[0031] Specifically, a T-plate 32 is fixed on the inclined arc plate 30, and the T-plate 32 is guidingly connected to the T-groove 31. The T-groove 31 can provide a moving guiding function for the inclined arc plate 30 through the T-plate 32. The inclined arc plate 30 can provide a support for the magnet 33. The annular groove 29 can provide a moving guiding and supporting function for the inclined arc plate 30. The positive pole of the magnet 33 faces away from the movable port 26. The inclined wheel 17 can provide a support for the magnetic ring 34. The positive pole of the magnetic ring 34 faces away from the center line of the inclined wheel 17. The magnet 33 and the magnetic ring 34 are matched with the same-sex repulsion, and the magnetisms of the magnet 33 and the magnetic ring 34 do not interfere with each other in the initial state.

[0032] Since there are gaps between multiple inclined arc plates 30, during the rotation along with the inclined rubber wheel 16, the gaps will move to a position close to the magnetic ring 34, resulting in a temporary disappearance of the magnetic force applied to the magnetic ring 34. As a result, the downward pressure applied to the inclined wheel 17 disappears, and the spring 48 will use the elastic force to push the inclined wheel 17 upward through the inner plate 47. At this time, the moving distance of the inclined wheel 17 will be affected by the distance of the gap, so that the upward moving distance of the inclined wheel 17 is less than the downward moving distance of the inclined wheel 17 pushed by the magnet 33 and the magnetic ring 34, preventing the inclined wheel 17 from repeatedly contacting the inclined rubber wheel 16 due to the gap.

[0033] In the actual application process of this embodiment, when the screw 6 is threadedly connected to the pin, the lower end of the sleeve 18 will contact the upper end of the pin. As the screw 6 is threadedly connected to the pin, the screw 6 will drive the plug rod 5, the longitudinal rod 4, the connecting cylinder 3, the T-rod 2, the connecting sleeve 9, the support plate 10, the electric rod 11 and the connecting plate 12 to move downward together by the threaded action with the pin, causing the telescopic plate 13 to contract and become shorter under the support of the support leg 14. At the same time, the abutting cylinder 21 will, under the resistance of the pin, drive the sleeve 18 to move upward along the guide block 20 by using the guide groove 19 as the screw 6 and the plug rod 5 move downward (relative to the plug rod 5 and the longitudinal rod 4). At the same time, the sleeve 18 will gradually push the side plate 23 and the pressure plate 24 upward as the screw 6 is threadedly connected to the pin under the resistance of the abutting cylinder 21 and the pin, causing the pressure plate 24 to drive the push rod 25 to move upward together. When the screw 6 is completely threadedly connected to the pin, the push rod 25 can contact the lower part of the push ring 27 and push the push ring 27 upward, causing the push ring 27 to drive the support rod 28 to move upward in the movable opening 26 by external force. The support rod 28 will cooperate with the inclined rubber wheel 16 to provide guidance for the push ring 27, so that the push ring 27 can push the inclined arc plate 30 close to the inclined surface of the movable opening 26 by using the arc and external force during the upward movement. The inclined arc plate 30 is pushed to translate along the annular groove 29 in the direction away from the center line of the inclined rubber wheel 16 under the action of the external force and the cooperation of its own inclined surface close to the movable opening 26. At the same time, the inclined rubber wheel 16 will drive the magnet 33 to move together, so that the magnet 33 can gradually move in the direction close to the magnetic ring 34, and the magnet 33 uses the magnetic force and the inclined angle to push the magnetic ring 34, so that the magnetic ring 34 can drive the inclined wheel 17 to move downward under the guidance of the connecting cylinder 3 by using the magnetic force, so that the inclined wheel 17 can be separated from the inclined rubber wheel 16, thus realizing automatically stopping driving the longitudinal rod 4 and the plug rod 5 to rotate and switching the driving force of the servo motor 15 after the threaded connection between the screw 6 and the plug pin is completed.

[0034] The knocking parts include: A support ring 38, fixed at the lower end of the servo motor 15 and located outside the driving end of the servo motor 15; A rotating disk 39, arranged below the support ring 38 and rotatably connected to the support ring 38; The V-shaped cylinder 40 is welded to the rotating disk 39 and is located outside the servo motor 15; The rail groove 41 is opened at the upper end of the V-shaped cylinder; The push plate 45 is arranged below the impact sleeve 8 and is guidingly connected to the rail groove 41 through a connecting member.

[0035] Specifically, the servo motor 15 can provide a stable support for the support ring 38. The support ring 38 can provide a rotational support for the rotating disk 39 by using bearings. The rotating disk 39 can provide a support for the V-shaped cylinder. The V-shaped cylinder 40 can provide a space for opening the rail groove 41. A guide ball 44 is inlaid and guidingly connected inside the rail groove 41. An impact rod 43 is welded above the guide ball 44. The impact rod 43 movably penetrates through the support plate 10, and the upper end of the impact rod 43 is fixedly connected to the push plate 45. The rotating disk 39 can drive the V-shaped cylinder to rotate by using an external force. The V-shaped cylinder 40 can provide a moving space and a guiding function for the guide ball 44 by using the rail groove 41, so that the guide ball 44 can reciprocally push the impact rod 43 and the push plate 45 to move up and down during the rotation of the V-shaped cylinder 40. A through hole 42 is penetrated and opened inside the support plate 10, and the through hole 42 is located outside the impact rod 43 and is staggered with the electric rod 11.

[0036] In the actual application process of this embodiment, during the process of the threaded connection between the screw rod 6 and the pin, the support rod 28 will push the connecting rod 35 to move upward, so that the connecting rod 35 drives the support block 36 and the plug 37 to move upward together, so that the plug 37 is inserted into the inner side of the ring groove 57. As the inclined rubber wheel 16 rotates, the inclined rubber wheel 16 will drive the support rod 28 to rotate together, so that the support rod 28 drives the connecting rod 35, the support block 36 and the plug 37 to rotate together, so that the support block 36 rotates along the inner side of the ring groove 57. As the sleeve 18 moves upward, after the screw rod 6 is completely threadedly connected to the plug pin, the support block 36 can drive the plug 37 to move and be inserted into the inner side of the fitting groove 58 together. Furthermore, the inclined rubber wheel 16 can drive the support block 36, the plug 37 and the rotating disk 39 to rotate together through the support rod 28 and the connecting rod 35, so that the rotating disk 39 can drive the V-shaped cylinder 40 to rotate together. The V-shaped cylinder 40 will use the rotational power and the rail groove 41 to push the guide ball 44 to reciprocally move up and down, so that the guide ball 44 drives the impact rod 43 to push the push plate 45 up and down under the guidance of the through hole 42. Furthermore, the push plate 45 can push the impact sleeve 8 to move up and down along the guide rod 1 during the reciprocating movement process. At the same time, the impact sleeve 8 will contact and impact the stop disk 7 upward by using inertia during this process, so that the stop disk 7 drives the guide rod 1, the T rod 2, the connecting sleeve 9, the support plate 10, the electric rod 11, the connecting plate 12, the longitudinal rod 4, the insertion rod 5 and the screw rod 6 to move upward together by using the impact force. Furthermore, the screw rod 6 can intermittently pull out the pin upward by using the upward impact force, and at the same time, it will drive the telescopic plate 13 to extend, thereby realizing the function of automatically and intermittently knocking to take out the pin. High-frequency and low-amplitude knocking (instead of violent hammering) is adopted to improve the energy transfer efficiency and the pin taking-out efficiency.

[0037] During the removal of the pin, the pin provides support for the insertion rod 5 and all components above it through the screw rod 6, thereby promoting the elongation of the telescopic plate 13 and supporting it to maintain its position after elongation.

[0038] As a preferred embodiment of the present invention, a ring groove 29 is formed on one side of the rotating disk 39 close to the inclined rubber wheel 16. The inside of the rotating disk 39 is evenly provided with fitting grooves 58, and the fitting grooves 58 communicate with the ring groove 29 and correspond to the position of the plug 37. A lubricating injection part is arranged in the connecting cylinder 3, and the lubricating injection part penetrates through the vertical rod 4 and the insertion rod 5 and is connected to the self-driving part. The lubricating injection part includes an extrusion part and a lubricating injection and discharge part. The extrusion part is elastically arranged in the connecting cylinder 3 and is connected to the follower part. The lubricating injection and discharge part is arranged on the vertical rod 4 and the insertion rod 5 and is connected to the extrusion part.

[0039] Specifically, the rotating disk 39 can provide a space for forming the ring groove 29 and the fitting grooves 58. The fitting grooves 58 can provide a fitting space for the plug 37. The ring groove 29 can provide a moving space for the plug 37 and the supporting block 36.

[0040] The extrusion part includes: Side ports 46 are formed through both sides of the connecting cylinder 3. The inner plate 47 is fixed to the inner side of the inclined wheel 17 and penetrates through the side ports 46. The spring 48 is arranged in the connecting cylinder 3 and is fixedly connected to the inner plate 47 through a connecting component.

[0041] Specifically, the connecting cylinder 3 can provide a space for forming the side ports 46. The side ports 46 can provide a through channel for the inner plate 47. The inner plate 47 can drive the connecting cylinder 3 to rotate under the drive of the rotation of the inclined wheel 17, so that the connecting cylinder 3 can drive the one-way valve 50 and the T-bar 2 to rotate together. The connecting cylinder 3 can provide a moving space and support for the spring 48.

[0042] The lubricating injection and discharge part includes: The corrugated cylinder 49 is arranged inside the spring 48, with one end fixedly connected to the connecting cylinder 3 and the other end fixedly connected to the inner plate 47. There are two one-way valves 50. One of them is fixed on the inner plate 47 and is connected to the upper end of the corrugated cylinder 49 through a pipeline. The other is fixed to the lower end of the corrugated cylinder 49, penetrates through the connecting cylinder 3 and is fixedly connected to the upper end of the vertical rod 4 through a fixing component. The filling pipe 51 penetrates through the connecting cylinder 3. The solenoid valve 52 is fixed to the lower end of the filling pipe 51 and penetrates through the inner plate 47 to be connected to the upper end of the corrugated cylinder 49. The inclined pipe 53 is fixed to the output end of one of the one-way valves 50 and communicates with the filling pipe 51, having an upward inclination angle. The filling and discharging part is arranged through the longitudinal rod 4 and the inserting rod 5 and is connected to the filling pipe 51.

[0043] Specifically, the connecting cylinder 3 can provide support for the corrugated cylinder 49. The corrugated cylinder 49 is made of a transparent material and can provide a storage space for lubricating oil. It can be squeezed, shrunk and folded under the action of an external force. The staff can observe the connecting cylinder 3 from the position of the side port 46 and observe the liquid level of the lubricating oil stored inside it through the connecting cylinder 3. The inner plate 47 and the connecting cylinder 3 can respectively provide support for the two one-way valves 50. The one-way valves 50 are of the valve flap type and can respectively provide a one-way flow channel from top to bottom for gas and lubricating oil. The filling pipe 51 can provide a flow channel for lubricating oil and air. The solenoid valve 52 can control the opening and closing of the flow channel of the filling pipe 51, so that the lubricating oil can pass through the filling pipe 51 and enter the inside of the corrugated cylinder 49. One of the one-way valves 50 can provide stable support for the inclined pipe 53. The upward inclination angle of the inclined pipe 53 can prevent the lubricating oil from entering its inside and can provide a flow channel for the air in the filling pipe 51.

[0044] The filling and discharging part includes: The guide hole 54 is opened through the upper ends of the longitudinal rod 4 and the inserting rod 5; The discharge hole 55 is symmetrically opened through the inserting rod 5 and is communicated with the guide hole 54; The filling hopper 56 is fixed to the upper end of the filling pipe 51.

[0045] Specifically, the guide hole 54 can provide a flow channel for lubricating oil. The discharge hole 55 has an inclination angle and can provide a discharge channel for the lubricating oil in the guide hole 54, so that the lubricating oil can be discharged between the sleeve 18 and the abutting cylinder 21 and the screw rod 6 and flow to the outside of the plug pin for lubrication.

[0046] In the actual application process of this embodiment, before using the extraction device, the staff can control the solenoid valve 52 to open, and inject lubricating oil into the inner side of the injection hopper 56, so that the lubricating oil can pass through the injection hopper 56 and enter the injection pipe 51. Subsequently, the lubricating oil will pass through the injection pipe 51 and the solenoid valve 52 and flow into the corrugated cylinder 49 for storage. After the corrugated cylinder 49 is filled, the solenoid valve 52 is controlled to close. When the inclined arc plate 30 is pushed to drive the magnet 33 to move away from the center line of the inclined rubber wheel 16, and the magnet 33 uses magnetic force and the inclination angle to push the magnetic ring 34 and the inclined wheel 17 to move downward along the connecting cylinder 3, the inclined wheel 17 will drive the inner plate 47 to move downward along the side port 46 together, so that the inner plate 47 can use external force to push the spring 48 and the corrugated cylinder 49 to contract and deform. When the corrugated cylinder 49 contracts and deforms, under the sealing of the solenoid valve 52 and one of the check valves 50, the lubricating oil stored in the corrugated cylinder 49 is extruded downward by external force, so that the lubricating oil can be squeezed into the other check valve 50, and the lubricating oil passes through the check valve 50 and enters the guide hole 54. When the spring 48 rebounds due to the gap between the inclined arc plate 30 and the magnet 33 and pushes the inner plate 47 and the corrugated cylinder 49 to stretch and reset upward, the corrugated cylinder 49 will suck the air in the injection pipe 51 into the inclined pipe 53 through the check valve 50 and the inclined pipe 53, so that the air in the inclined pipe 53 can be squeezed into the check valve 50, and the air in the check valve 50 can pass through the check valve 50 and enter the corrugated cylinder 49, so that the corrugated cylinder 49 can use air to extrude and discharge lubricating oil next time. The lubricating oil discharged into the guide hole 54 will flow downward along the guide hole 54 under the action of gravity and vibration, pass through the guide hole 54 and flow into the discharge hole 55, and finally pass through the discharge hole 55. Under the blocking and guiding of the sleeve 18 and the abutting cylinder 21, it is discharged to the outside of the screw 6 and the plug, thereby realizing the functions of lubricating the plug and dissolving rust, and improving the efficiency and effect of pin extraction.

[0047] Working principle: The distance between the supporting feet 14 is adjusted by the telescopic movement of the electric rod 11 to adapt to different working environments. The rubber pads at the bottom of the supporting feet 14 provide stable support to ensure the vertical positioning of the device. The screw 6, the inserting rod 5 and the sleeve 18 are inserted into the hole where the pin is located. After the supporting feet 14 are fixed, the connecting sleeve 9 supports the T-bar 2 to keep it vertical, providing a basis for subsequent operations.

[0048] Start the servo motor 15, the inclined rubber wheel 16 rotates, and drives the connecting cylinder 3, the T-bar 2, the longitudinal rod 4, the inserting rod 5 and the screw 6 to rotate as a whole through the frictional force between the inclined surface and the inclined wheel 17. The screw 6 is automatically thread-connected to the upper end of the pin by using the rotational power and gravity. The sleeve 18 moves down with the screw 6 to contact the pin, triggering the action of the abutting member. The screw 6 and the abutting cylinder 21 can be quickly replaced to be compatible with pins of different sizes.

[0049] After the screw rod 6 is fully connected, the push rod 25 moves upward to push the push ring 27. The inclined arc plate 30 drives the inclined wheel 17 to move downward under the action of magnetic force, disengaging from the contact with the inclined rubber wheel 16 and stopping the rotation drive. The inclined rubber wheel 16 drives the rotating disk 39 to rotate through the support rod 28 and the connecting rod 35. The guide ball 44 is pushed up and down by the rail groove 41 of the V-shaped cylinder 40, driving the impact sleeve 8 to reciprocally impact the stop disk 7 along the guide rod 1. The stop disk 7 transmits the impact force to the guide rod 1 and the screw rod 6, achieving high-frequency and low-amplitude knocking, gradually pulling out the pin. The servo motor 15 drives the screw rod 6 to automatically screw into the pin without manual intervention. After the threaded connection is completed, the abutting cylinder 21, the sleeve 18, the magnet 33 and the magnetic ring 34 automatically switch to the knocking mode, reducing the operation steps.

[0050] Lubricating oil is filled into the corrugated cylinder 49 through the filling hopper 56. The solenoid valve 52 controls the opening and closing of the oil circuit. When the inclined wheel 17 moves downward, it squeezes the corrugated cylinder 49, and the lubricating oil flows to the contact surface between the screw rod 6 and the pin through the guide hole 54 and the discharge hole 55; when the inclined wheel 17 resets, air is inhaled to supplement the pressure, realizing continuous lubrication. The corrugated cylinder 49 and the check valve 50 realize the automatic injection of lubricating oil, reducing friction loss, prolonging the service life of the device, weakening the friction force of the pin, and accelerating the removal of the pin.

[0051] Through the synergistic effect of automatic drive, intelligent mode switching, high-frequency impact and self-lubrication system, efficient and low-loss operation of pin removal is achieved, while reducing manual dependence and maintenance costs.

[0052] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
