Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to an oil seal spring device. Background Art

[0002] The oil seal sleeve spring device gives the oil seal a strong sealing effect through the built-in spring. The spring provides continuous elastic force inside the oil seal sleeve, so that the oil seal and the sealed component fit tightly, effectively preventing oil leakage. Its working principle is that when the oil seal sleeve is installed in place, the elastic force of the spring keeps the oil seal in a certain compression state at all times. The oil seal fits tightly on the sealed component to form an efficient sealing ring, preventing oil from leaking through the gap. During use, the elasticity of the spring can maintain the long-term stability of the sealing performance of the oil seal. Even if the oil temperature changes or vibrations occur during the operation of the equipment, the spring can still provide stable pressure to ensure that the oil seal always maintains a good sealing effect, thereby significantly extending the service life of the mechanical components and improving the reliability of the overall system. During assembly, the assembly device precisely assembles the oil seal spring on the oil seal sleeve to ensure that the spring can accurately exert its elastic effect.

[0003] However, there are at least the following problems in the prior art:

[0004] The existing assembly device cannot guarantee the accurate position of the spring and the oil seal, resulting in position deviation when the spring and the oil seal are connected, affecting the spring assembly efficiency; in addition, the spring may be deformed or damaged during the spring assembly process, which will also affect the sealing effect of the oil seal. Especially in a high-temperature working environment, the elasticity of the spring will be reduced, further affecting the sealing performance of the oil seal, thereby shortening the service life of mechanical components and reducing system reliability. Summary of the Invention

[0036] The following will be combined with the Figure 1 To the attached Figure 13 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The oil seal spring device includes a conveying mechanism 1, a flipping and retrieving mechanism 2, an automatic alignment mechanism 3, and a pneumatic expander 4. It also includes a feeding mechanism 5 fixedly mounted on the top of the flipping and retrieving mechanism 2. The flipping and retrieving mechanism 2 is fixedly mounted on one side of the top of the conveying mechanism 1. The flipping and retrieving mechanism 2 consists of a mounting frame 201, a flipping shaft 204, a rack 205, a drive assembly 206, a lifting seat 207, and a flipping seat 208. A gear 2041 is fixedly mounted on one end of the flipping shaft 204, and the gear 2041 is meshed with the rack 205.

[0038] The pneumatic expander 4 is fixedly mounted on the bottom of the flip seat 208, and the automatic alignment mechanism 3 is fixedly mounted on the bottom of the pneumatic expander 4. The pneumatic expander 4 is driven to flip by the flipping and material-retrieving mechanism 2, and the flipped pneumatic expander 4 flexibly expands the oil seal spring to retrieve and discharge the material.

[0039] Among them, the driving component 206 drives the lifting seat 207 to move back and forth vertically, and the vertically reciprocating lifting seat 207 drives the flip shaft 204 to move vertically, and the vertically moving flip shaft 204 drives the gear 2041 to move vertically. When the gear 2041 moves on one side of the rack 205, the gear 2041 rotates with the meshing of the rack 205, driving the flip shaft 204 to rotate, thereby realizing that the pneumatic expander 4 drives the automatic alignment mechanism 3 to flip and move upward, and the flipped and moved automatic alignment mechanism 3 pushes up and takes material from the blanking mechanism 5, and utilizes the pneumatic expander 4 to uniformly expand the inner diameter of the spring through the pneumatic expansion airbag 402, thereby realizing flexible expansion and fixing the position of the spring, avoiding local stress concentration caused by manual expansion, and reducing the deformation rate during the spring assembly process;

[0040] The automatic alignment mechanism 3 consists of a servo motor 301, an expansion assembly 302, a mounting sleeve 303, six expansion rods 306, three return elastic members 307, and a second tapered rod 308. The three return elastic members 307 for flexible expansion and discharging are equidistantly embedded in the outer wall of the mounting sleeve 303 by bolts. The two ends of the return elastic members 307 are respectively connected to one end of the two expansion rods 306. The two expansion rods 306 and the return elastic member 307 form a set of expansion and centering mechanisms. The six expansion rods 306 and the three return elastic members 307 form three sets of expansion and centering mechanisms.

[0041] The servo motor 301 drives the expansion assembly 302 to rotate, and the rotating expansion assembly 302 drives the second tapered rod 308 to move. The moving second tapered rod 308 pushes the expansion rod 306 to move outward, thereby realizing the automatic alignment of the oil seal sleeve by the three sets of expansion centering mechanisms;

[0042] The servo motor 301 drives the expansion component 302 to rotate, and the expansion component 302 cooperates with the second tapered rod 308 connected by a thread. When the expansion component 302 rotates, the second tapered rod 308 is driven to move. When the second tapered rod 308 moves to the maximum stroke, the expansion component 302 that continues to rotate moves close to the second tapered rod 308. The expansion component 302 and the second tapered rod 308 that move relatively move to support the six expansion rods 306 to move outward, thereby expanding the three groups of expansion and centering mechanisms. The expanded three groups of expansion and centering mechanisms are used to contact the inner wall of the oil seal sleeve conveyed by the conveying mechanism 1. The synchronously expanded three groups of expansion and centering mechanisms realize automatic alignment and position locking of the oil seal sleeve, thereby preventing position deviation between the spring and the oil seal sleeve during assembly, thereby improving the spring assembly efficiency.

[0043] When releasing the position lock of the oil seal sleeve, the expansion assembly 302 is rotated in the reverse direction so that the expansion assembly 302 and the second tapered rod 308 are separated, thereby releasing the interference of the second tapered rod 308 and the expansion assembly 302 on the expansion rod 306, and the elastic reset force of the reset elastic member 307 is used to reset the expansion rod 306, thereby releasing the interference lock of the expansion rod 306 on the inner wall of the oil seal sleeve.

[0044] The expansion assembly 302 is movably mounted inside the mounting sleeve 303. The top of the expansion assembly 302 is engaged with the spline sleeve at the output end of the servo motor 301. The bottom end of the expansion assembly 302 is threadedly connected to the second tapered rod 308. The bottom end of the mounting sleeve 303 is threadedly mounted with a sleeve head 304. A guide block 305 is fixedly mounted on the inner wall of the sleeve head 304. The second tapered rod 308 is movably mounted inside the sleeve head 304 through the guide block 305.

[0045] Among them, the servo motor 301 is clamped with the top of the expansion component 302 through the spline sleeve. When the servo motor 301 drives the expansion component 302 to rotate through the spline sleeve, it does not affect the linear movement of the expansion component 302. When the expansion component 302 rotates, it drives the threaded second tapered rod 308 to move. The guide block 305 inside the sleeve 304 ensures that the second tapered rod 308 can be accurately guided along the predetermined path. When the second tapered rod 308 moves to the maximum stroke, the expansion component 302 that continues to rotate moves close to the second tapered rod 308, and the three sets of expansion centering mechanisms are driven to expand by using the relatively moving expansion component 302 and the second tapered rod 308.

[0046] The expansion assembly 302 consists of a transmission rod 3021, a first tapered rod 3022, a spline rod 3023, and a threaded rod 3024. One end of the first tapered rod 3022 is fixedly mounted on the top of the transmission rod 3021, the bottom end of the spline rod 3023 is fixedly mounted on the other end of the first tapered rod 3022, and the top end of the threaded rod 3024 is fixedly mounted on the bottom of the transmission rod 3021.

[0047] The servo motor 301 cooperates with the splined rod 3023 to drive the transmission rod 3021 to rotate through the spline sleeve, driving the first tapered rod 3022 and the threaded rod 3024 fixed on the top to rotate together. The rotating threaded rod 3024 drives the threaded second tapered rod 308 to move, and the guide block 305 ensures that the second tapered rod 308 can be accurately guided along the predetermined path. When the second tapered rod 308 moves to the maximum stroke, the guide groove inside the mounting sleeve 303 will limit the second tapered rod 308 from continuing to move. The transmission rod 3021 continues to rotate, driving the threaded rod 3024 to extend to the second tapered rod 308, so that the spline rod 3023 fixed at the other end of the first tapered rod 3022 moves along its axial direction, realizing the conversion of the rotation of the transmission rod 3021 into a linear displacement of the stroke, and finally achieving the linear displacement of the first tapered rod 3022. The linearly displaced first tapered rod 3022 pushes the expansion rod 306 to move outward, completing the mechanical expansion operation of the expansion rod 306, and ensuring the stability and reliability of the expansion process.

[0048] The pneumatic expander 4 is composed of a conical seat 401, a pneumatic expansion balloon 402, and a pneumatic pump 403. The pneumatic expansion balloon 402 is embedded in the outer wall of the conical seat 401. The pneumatic pump 403 is connected to the pneumatic expansion balloon 402 via a pipe, and the pneumatic pump 403 is fixedly mounted on the top of the flip seat 208.

[0049] Among them, the conical seat 401 provides support and positioning for the pneumatic expansion airbag 402, ensuring stability and accuracy during the expansion process; the pneumatic expansion airbag 402 is embedded in the outer wall of the conical seat 401, and when the pneumatic pump 403 injects compressed air into the pneumatic expansion airbag 402 through the pipeline, the pneumatic expansion airbag 402 is inflated, thereby expanding and fixing the spring; an exhaust valve is installed on the inner side of the pneumatic expansion airbag 402 through the pipeline, and the exhaust valve is used to discharge the air inside the pneumatic expansion airbag 402, thereby realizing the contraction control of the pneumatic expansion airbag 402, and facilitating the release of the expansion and fixation of the spring by the pneumatic expansion airbag 402.

[0050] The rack 205 is fixedly mounted on the back of the mounting frame 201. A movable chute 202 is provided along the longitudinal centerline of the mounting frame 201. Guide chute 203 is provided on both sides of the front of the mounting frame 201. A lifting seat 207 is movably mounted on the front of the mounting frame 201 through the guide chute 203. A tilting shaft 204 is movably mounted inside the movable chute 202. The tilting shaft 204 extends to the front of the lifting seat 207. A tilting seat 208 is fixedly mounted on the front of the tilting shaft 204. Blocks are equidistantly mounted on the outer wall of the tilting shaft 204.

[0051] Among them, the movable slide 202 provides an installation position for the flip shaft 204, which is convenient for limiting the moving direction of the flip shaft 204; two sliders are fixedly installed on both sides of the back of the lifting seat 207, and the two sliders extend to the inside of the guide slide 203 for movability connection, and the lifting seat 207 moves stably through the cooperation of the sliders and the guide slide 203; the rotating flip shaft 204 is used to drive the flip seat 208 to move and flip in the vertical direction, and the vertically moving and flipping flip seat 208 drives the pneumatic expander 4 and the automatic positioning mechanism 3 to move and flip in the vertical direction to complete the material picking and placing.

[0052] Mounting slots are provided at the top and bottom of both sides of the movable slide 202. A return spring 2021 is fixedly installed inside the mounting slot. A locking seat 2022 is fixedly installed on the top of the return spring 2021. The inner wall of the locking seat 2022 has slots equidistantly provided. When the tilt shaft 204 moves down to the top of the locking seat 222 and contacts it, the slots on the inner wall of the locking seat 222 cooperate with the blocks on the outer wall of the tilt shaft 204 to lock the tilt shaft 204.

[0053] Among them, when the flip shaft rod 204 moves down to the top of the locking seat 2022 and is connected with the collision, the card groove on the inner wall of the locking seat 2022 is used to cooperate with the card block on the outer wall of the flip shaft rod 204 to lock the position of the flip shaft rod 204, thereby preventing the flip shaft rod 204 from flipping and achieving stable maintenance of the flip state. At this time, the reset spring 2021 is compressed, releasing the elastic potential energy, and improving the locking stability; when the flip shaft rod 204 moves up to disengage from the locking seat 2022, the position lock of the flip shaft rod 204 is released, and the flip shaft rod 204 can rotate freely, and automatically reset under the elastic restoring force of the reset spring 2021, thereby achieving stable maintenance of the flip state and continuous operation of the reset process.

[0054] The drive assembly 206 consists of a servo motor 2061, a rotating wheel 2062, and an electric push rod 2063. The servo motor 2061 is fixedly mounted on the back of the mounting frame 201. The rotating wheel 2062 is rotatably mounted on the front of the mounting frame 201. The back of the rotating wheel 2062 is fixedly connected to the output end of the servo motor 2061. The top end of the electric push rod 2063 is mounted on the front of the rotating wheel 2062 via a shaft bolt. The bottom end of the electric push rod 2063 is movably connected to the lifting base 207 via a shaft bolt.

[0055] Among them, the electric push rod 2063 is self-locking through the worm gear transmission mechanism, so that when the servo motor 2061 drives the rotating wheel 2062 to rotate, the rotating rotating wheel 2062 drives the lifting seat 207 to move up and down through the electric push rod 2063 in the self-locking state; and the telescopic length is adjusted by energizing the electric push rod 2063, so that the displacement stroke of the lifting seat 207 can be adjusted; when the lifting seat 207 drives the flip shaft 204 to move down to the top of the locking seat 2022 to abut against the connection, the electric push rod 2063 is energized to drive the lifting seat 207 to continue to move downward, so that the lifting seat 207 drives the pneumatic expander 4 and the automatic alignment mechanism 3 below the flip seat 208 to move vertically, so that the automatic alignment mechanism 3 moves down into the oil seal sleeve, and the downward-moving pneumatic expander 4 discharges air through the exhaust valve to release the fixed spring. Since the pneumatic expander 4 is conical, the spring slides along the pneumatic expander 4 into the oil seal sleeve to achieve the assembly of the spring.

[0056] The unloading mechanism 5 is composed of a bracket 501, a placing cylinder 502 and an intermittent unloading assembly 503, wherein the placing cylinder 502 is fixedly mounted on the top of the bracket 501, the intermittent unloading assembly 503 is hoisted inside the placing cylinder 502, and the intermittent unloading assembly 503 is composed of a mounting tube 5031, a telescopic spring 5032, a telescopic rod 5033, an expansion spring 5034, a limiting shaft rod 5035 and a push rod 5036. The telescopic spring 5032 is fixedly mounted inside the mounting tube 5031, the telescopic rod 5033, the expansion spring 5034, the limiting shaft rod 5035 and the push rod 5036. The retracting rod 5033 is movably mounted within the mounting tube 5031, and the bottom end of the telescopic spring 5032 is fixedly connected to the top end of the telescopic rod 5033. A top rod 5036 is fixedly mounted to the bottom end of the telescopic rod 5033. Four equally spaced limiting shafts 5035 are mounted on the outer wall of the top rod 5036 via axle bolts. Four expansion springs 5034 are fixedly mounted on the tops of the four limiting shafts 5035. The top ends of the four expansion springs 5034 are fixedly connected to the bottom end of the telescopic rod 5033.

[0057] Among them, the telescopic spring 5032 is fixedly installed in the mounting tube 5031, providing elastic support for the movement of the telescopic rod 5033, and the telescopic rod 5033 can freely expand and contract inside the mounting tube 5031, and its top end is fixedly connected to the bottom end of the telescopic spring 5032 to ensure the stability of the telescopic movement; when the automatic alignment mechanism 3 flips to the top, the electric push rod 2063 drives the automatic alignment mechanism 3 to continue to move upward through the lifting seat 207, and the upward moving automatic alignment mechanism 3 resists the push rod 5036 and moves upward, and the upward moving push rod 5036 drives the telescopic rod 5033 and the limiting shaft rod 5035 to move upward, and the upward moving limiting shaft rod 5035 shrinks and moves upward toward the inside of the mounting tube 5031, and the upward shrinking limiting shaft rod 5035 releases the lock on the spring, and the setting spring slides to the outside of the pneumatic expander 4 through the automatic positioning mechanism 3 under the influence of gravity, and the spring is expanded and fixed by the pneumatic expander 4. At this time, the expansion spring 5034 is stretched and the telescopic spring 5032 is compressed. When the automatic positioning mechanism 3 moves down and flips to release the resistance to the push rod 5036, the elastic reset force of the telescopic spring 5032 is used to drive the push rod 5036 to move downward, and the expansion spring 5034 is gradually released from tension. The released expansion spring 5034 drives the limit shaft 5035 to reset; at the same time, the elastic force of the telescopic spring 5032 will cause the push rod 5036 to return to its initial position when unloading, thereby realizing intermittent quantitative unloading of materials.

[0058] A position sensor 101 is fixedly installed on the other side of the top of the conveying mechanism 1, and a PLC controller 102 is fixedly installed on the side of the top of the conveying mechanism 1 close to the position sensor 101;

[0059] Among them, the PLC controller 102 is electrically connected to the position sensor 101, the servo motor 2061, the electric push rod 2063, the servo motor 301, and the pneumatic pump 403 through wires. The PLC controller 102 presets the parameters of the servo motor 2061, the electric push rod 2063, the servo motor 301, and the pneumatic pump 403 according to the specifications of the spring and the oil seal sleeve; the PLC controller 102 receives and analyzes the feedback signal from the position sensor 101, and then adjusts the working status of the servo motor 2061, the electric push rod 2063, the servo motor 301, and the pneumatic pump 403 through a preset control strategy according to the specific specifications of the spring and the oil seal sleeve, ensuring that every action in the installation process can be accurately positioned, and ultimately achieving the goal of high-precision assembly of the oil seal spring.
