Description

Technical Field

[0001] This invention discloses a technical field of stabilizer bar outer bushing, specifically relating to a stabilizer bar bushing fabrication machine. Background Technology

[0002] Stabilizer bar bushings are key components in automotive suspension systems, primarily functioning to support the stabilizer bar, buffer vibrations, absorb shocks, and reduce road noise. As the automotive industry's demands for ride comfort and quietness continue to rise, the design and manufacturing processes of stabilizer bar bushings have also undergone continuous evolution. Among these advancements, adding a Teflon (PTFE) fabric liner to the inner surface of the bushing's bore has become a widely adopted noise reduction technique. Teflon material possesses an extremely low coefficient of friction and excellent wear resistance. By introducing a Teflon fabric sliding layer between the stabilizer bar and the rubber bushing, frictional noise generated by direct contact between the stabilizer bar and the rubber during torsion can be effectively avoided.

[0003] Currently, the bonding of Teflon fabric linings and rubber bushings is usually achieved through vulcanization molding. The typical manufacturing process is as follows: a tubular Teflon fabric lining is fitted over the shaft, and then the shaft with the Teflon fabric lining is placed into the mold cavity. Rubber is injected for vulcanization molding, which bonds the fabric and the rubber elastomer together. In this process, the process of fitting the tubular Teflon fabric lining over the shaft is a key step that determines product quality and production efficiency.

[0004] However, the current "cloth application" process generally relies on manual operation. When operators manually slip the tubular Teflon fabric over the shaft, they need to ensure the fabric is flat and wrinkle-free against the outside of the shaft. This manual method has the following problems: 1. Poor quality stability: When manually applying the fabric, it is difficult to precisely control the tension and uniformity of the fabric, which can easily lead to defects such as fabric wrinkles, misalignment or local looseness. This directly affects the bonding quality between the fabric lining and the rubber after subsequent vulcanization molding, and thus affects the noise reduction effect and service life of the finished lining. 2. Low production efficiency: The fabric application process relies entirely on manual labor, and each product takes a long time to complete, making it difficult to meet the needs of large-scale automated production. 3. High labor intensity: Fabric application requires delicate manual skills and a high degree of proficiency from the operators. Long-term repetitive work can easily lead to fatigue; once fatigued, errors are more likely to occur. 4. Difficulty in ensuring product consistency: The quality of the lining varies greatly between different operators and different batches, making it difficult to control the quality consistency of the finished lining and hindering the standardization of product quality.

[0005] Therefore, it is particularly important to design a fabric covering machine that can be used in the fabric covering process to achieve automated operation, improve work efficiency, and ensure quality stability. Summary of the Invention

[0006] The purpose of this invention is to provide a stabilizer bar bushing fabrication machine to solve the existing problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stabilizer bar bushing covering machine, comprising a frame and an air source, wherein an operating table, a shaft release button, a cloth release button, an assembly button, and an emergency stop button are provided on the table surface of the frame, and a first mounting through hole is provided in the center of the operating table, and a controller for controlling the operation of the equipment is provided inside the frame, the controller being electrically connected to the air source, the shaft release button, the cloth release button, the assembly button, and the emergency stop button, a mounting base is provided below the first mounting through hole, an inner lining cloth positioner is provided in the central through hole of the mounting base, and a second mounting through hole is provided in the center of the inner lining cloth positioner, concentrically arranged with the second mounting through hole, and one or more arc-shaped positioning pieces are distributed circumferentially above the inner lining cloth positioner, with a gap between adjacent arc-shaped positioning pieces, the arc-shaped positioning pieces protruding from the upper end surface of the mounting base, and in each Each arc-shaped positioning piece has limiting steps distributed along its outer wall. All limiting steps cooperate to form an annular step for positioning the inner lining fabric. All arc-shaped positioning pieces cooperate to form a circular support clamp for fitting the inner lining fabric. A cylinder is installed at the bottom of the frame. The piston rod of the cylinder is connected to a shaft positioning rod that extends out of the mounting through hole two when raised and separates from the inner lining fabric positioner when lowered. A pneumatic ring is installed between the mounting base and the operating table. The outer wall of the pneumatic ring has one or more pneumatic connectors distributed circumferentially. Each pneumatic connector is connected to a push head that pushes against the space between two adjacent arc-shaped positioning pieces. When the pneumatic connector is inflated, the push head is used to move the two adjacent arc-shaped positioning pieces toward the center of the mounting through hole two to reduce the size of the circular support clamp. The air source is used to pneumatically connect with each pneumatic connector to supply air to the pneumatic connector.

[0008] Preferably, to limit the direction of the external clamp movement, the mounting base includes a straight section and a trapezoidal section below the straight section. The upper part of the straight section is inserted into the pneumatic ring. A lifting plate located below the pneumatic ring is slidably connected to the straight section. One or more hinged arms are distributed circumferentially on the lifting plate. Each hinged arm extends longitudinally through the pneumatic ring and the upper and lower parts of the lifting plate. Both sides of each hinged arm are hinged to the lifting plate through a hinge shaft. An external clamp for engaging with the outer wall of the inner lining is provided above each hinged arm. All external clamps engage with a circular clamp for clamping the outer wall of the inner lining. A guide wheel is rotatably connected below each hinged arm. The guide wheel can fit against the outer wall of the trapezoidal section and rotate along the outer wall of the trapezoidal section when the lifting plate moves up and down. A mounting plate is fixed to the bottom of the trapezoidal section. A cylinder is fixed to each side of the mounting plate. The piston rods of the two cylinders are connected to the two sides of the bottom of the lifting plate.

[0009] To facilitate the reset of the external clamp, a spring groove is provided below each hinge arm, and all spring grooves are used to fit a reset spring.

[0010] In order to automatically detect whether there is an inner lining cloth inside the ring support clamp, a pair of photoelectric sensors are set on both sides of the platform of the frame opposite to the mounting through hole one, and the two photoelectric sensors cooperate with each other.

[0011] In order to increase the friction between the corresponding clamp and the outer and inner walls of the inner lining and further clamp the inner lining, the outer clamp is provided with one or more anti-slip ribs on the side facing the second mounting hole, and the arc-shaped positioning piece is provided with one or more anti-slip ribs on the side facing the second mounting hole.

[0012] For ease of assembly, a partition is provided at the center of the frame to separate the frame into upper and lower layers. The first cylinder is provided at the bottom of the partition. The piston rod of the first cylinder passes through the partition and is connected to a lifting plate. The shaft positioning rod is provided above the lifting plate.

[0013] In order to guide the shaft positioning rod when it moves up and down, the partition plate is provided with one or more guide sleeves, and the bottom of the lifting plate is provided with a guide rod that is slidably connected to the guide sleeve.

[0014] To facilitate the movement of this device, four omnidirectional casters are provided at the bottom of the frame.

[0015] Preferably, when the size of the ring support is reduced, the inner lining fabric can be fitted over the ring support.

[0016] Compared with the prior art, the beneficial effects of the present invention are: this structure only requires manual placement of the shaft and fabric to achieve rapid assembly of the shaft and fabric. Compared with the current manual fabric placement process, this structure has the following technical advantages: 1. High quality stability: This structure solves the problem of difficulty in accurately controlling the tension and uniformity of the fabric when manually applying it. When applying the fabric, the lower end of the fabric is clamped first, which can avoid defects such as fabric wrinkles, shifts or local looseness during the application process. 2. High production efficiency: The entire fabric application process is automated, and the operator only needs to place the roller and the fabric, which further improves production efficiency. 3. Low labor intensity: The entire fabric application process does not require fine manual skills and does not require a high level of proficiency from the operators; 4. Product consistency can be guaranteed: Since the entire fabric covering operation is automated, the manual labor only needs to place the shaft and the fabric. During the fabric covering process, the lower end of the fabric is clamped first, and the clamping force is consistent. As a result, the quality difference between different batches of fabric covering is not significant, which further ensures the consistency of the finished liner quality and is conducive to the standardization of product quality.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] Example 1 Please see Figures 1-8As shown, this embodiment discloses a stabilizer bar bushing covering machine, including a frame 1 and an air source 2. To facilitate movement of the device, four universal casters 22 are provided at the bottom of the frame 1. An operating table 3, a shaft-laying button 4, a cloth-laying button 5, an assembly button 6, and an emergency stop button 7 are provided on the platform of the frame 1. A mounting through hole 301 is provided in the center of the operating table 3. A controller 24 for controlling the operation of the device is provided inside the frame 1. The controller 24 is electrically connected to the air source 2, the shaft-laying button 4, the cloth-laying button 5, the assembly button 6, and the emergency stop button 7. Next, a mounting base 8 is provided below the mounting through hole 301. An inner lining cloth positioner 9 is provided in the central through hole of the mounting base 8. A second mounting through hole 10, concentrically arranged with the mounting through hole 301, is provided at the center of the inner lining cloth positioner 9. Above the inner lining cloth positioner 9, one or more arc-shaped positioning pieces 11 are distributed circumferentially, with a gap D between adjacent arc-shaped positioning pieces 11. The arc-shaped positioning pieces 11 protrude from the upper end face of the mounting base 8. Limiting steps 12, distributed along the outer wall of each arc-shaped positioning piece 11, are provided on the outer side of each arc-shaped positioning piece 11. All limiting steps 12 cooperate to form a... The annular step for positioning the inner lining fabric, with all the arc-shaped positioning pieces 11 cooperating to form a circular support clamp for fitting the inner lining fabric, is provided at the bottom of the frame 1. A cylinder 13 is provided at the bottom of the frame 1. A shaft positioning rod 14 is connected to the piston rod of the cylinder 13, which extends out of the mounting through hole 10 when raised and separates from the inner lining fabric positioner 9 when lowered. A pneumatic ring 15 is provided above the mounting base 8 and between the operating table 3. The outer wall of the pneumatic ring 15 has one or more pneumatic connectors 16 distributed circumferentially. Each pneumatic connector 16 is connected to a push head 17 that pushes against the space between two adjacent arc-shaped positioning pieces 11. The push head 17 is used to follow the air... When the movable connector 16 is inflated, it is used to move two adjacent arc-shaped positioning pieces 11 toward the center of the mounting through hole 2 10 to reduce the size of the circular support clamp. The air source 2 is used to pneumatically connect with each pneumatic connector 16 to supply air to the pneumatic connector 16. When an inner lining is needed, the size of the circular support clamp is reduced so that the inner lining can be fitted outside the circular support clamp. The controller 24 also needs to be electrically connected to the air source 2, each cylinder, and the through-beam sensor 812 to realize the automated control of the equipment. As for how the controller 24 realizes the automatic control design, it belongs to the conventional technology in this field, so it will not be described in detail.

[0021] Preferably, to limit the direction of change of the external clamp 806, the mounting base 8 includes a straight section 801 and a trapezoidal section 802 located below the straight section 801. The upper part of the straight section 801 is inserted into the pneumatic ring 15, and a limiting protrusion 8011 is provided on the straight section 801 to limit its movement. A lifting plate 803 located below the pneumatic ring 15 is slidably connected to the straight section 801. One or more hinge arms 804 are distributed circumferentially on the lifting plate 803. Each hinge arm 804 longitudinally penetrates the pneumatic ring 15 and the lifting plate 803, and each hinge arm 804 is connected to a hinge shaft 80 on both sides. 5. Hinged within the lifting plate 803, each hinge arm 804 has an outer clamp 806 above it for engaging with the outer wall of the inner lining fabric. All outer clamps 806 engage with a ring clamp for clamping the outer wall of the inner lining fabric. A guide wheel 807 is rotatably connected below each hinge arm 804. When the lifting plate 803 moves up and down, the guide wheel 807 can fit against the outer wall of the trapezoidal part 802 and rotate along the outer wall of the trapezoidal part 802. A mounting plate 808 is fixed to the bottom of the trapezoidal part 802. A cylinder 809 is fixed to each side of the mounting plate 808. The piston rods of the two cylinders 809 are respectively connected to the two sides of the bottom of the lifting plate 803.

[0022] To facilitate the reset of the external clamp 806, a spring groove 810 is provided below each hinge arm 804, and all spring grooves 810 are used to fit a reset spring 811.

[0023] In order to automatically detect whether there is an inner lining cloth inside the ring support clamp, a pair of photoelectric sensors 812 are provided on both sides of the platform of the frame 1 relative to the mounting through hole 301, and the two photoelectric sensors 812 cooperate with each other.

[0024] In order to increase the friction between the corresponding clamp and the outer and inner walls of the inner lining and further clamp the inner lining, the outer clamp 806 is provided with one or more anti-slip ribs 813 on the side facing the second mounting hole 10, and the arc-shaped positioning piece 11 is provided with one or more anti-slip ribs 814 on the side facing the second mounting hole 10.

[0025] For ease of assembly, a partition 18 is provided at the center of the frame 1 to separate the frame 1 into upper and lower layers. A cylinder 13 is provided at the bottom of the partition 18. The piston rod of the cylinder 13 passes through the partition 18 and is connected to a lifting plate 19. A shaft positioning rod 14 is provided above the lifting plate 19. The head of the shaft positioning rod 14 extends out of the frame 1. The operator can insert the bottom of the shaft 23 into the head of the shaft positioning rod 14, and then drive the lower cylinder 13 to move the shaft 23 down until it is located below the circular support clamp, so as to facilitate the placement of the cloth lining outside the circular support clamp.

[0026] In order to guide the shaft positioning rod 14 when it moves up and down, the partition plate 18 is provided with one or more guide sleeves 20, and the bottom of the lifting plate 19 is provided with a guide rod 21 that is slidably connected in the guide sleeve 20. In this embodiment, in order to facilitate the guidance of the shaft positioning rod 14 when it moves up and down, the guide rod 21 and the guide sleeve 20 are used to achieve the same effect, so as to avoid the shaft positioning rod 14 from shifting position when it moves up and down, which would prevent the shaft rod 23 from being inserted into the shaft positioning rod 14 smoothly in the later stage.

[0027] The working principle of this structure is as follows: Because the inner lining fabric is a cylindrical structure, during use... First, press the shaft release button 4. Cylinder 13 will work to drive the shaft positioning rod 14 to rise outside the frame 1. At this time, the cylinder will stop working (it should be noted that the stroke distance of the cylinder can be preset according to requirements. Once set, the cylinder will stop working when it reaches the stroke path. The setting of the cylinder stroke distance is a conventional technology in the field, so it will not be described in detail). Manually release the material and insert the shaft rod 23 into the exposed shaft positioning rod 14. Then, press and hold the cloth release button 5. At this time, the air source 2 supplies air to each pneumatic connector 16. The pneumatic connector 16 pushes the push head 17 to work towards the center of the second mounting hole 10, which reduces the size of the entire ring support clamp. At the same time, the second cylinder 809 works, driving the hinge arm 804 to move down, which makes the upper ring clamp 1 open outward. At this time, the inner lining cloth is quickly inserted between the ring support clamp and the ring clamp 1, ensuring that the lower end of the inner lining cloth is placed on the limiting step 12. Then release the cloth release button 5. The second cylinder 809 resets, the pneumatic connector 16 exhausts air, ensuring that the ring clamp 1 resets and becomes smaller and clamps the outer wall of the inner lining cloth, and the ring support clamp resets and becomes clamped on the inner wall of the inner lining cloth, finally clamping the lower part of the inner lining cloth. Finally, press the assembly button 6. At this time, cylinder 13 will work to drive the shaft positioning rod 14 to rise, so that the shaft 23 slowly approaches the bottom of the inner lining and is inserted from the bottom of the inner lining until the shaft positioning rod 14 rises to be placed outside the frame 1, ensuring that the entire shaft 23 passes through the entire inner lining. Then the lower outer clamp 806 is released, making it convenient for the user to remove and assemble. This completes the process of putting the inner lining on the shaft 23. Repeat the above steps to realize the automatic assembly process of the shaft 23 and the inner lining.

[0028] Therefore, this structure allows for rapid assembly of the shaft and fabric using only manual placement of the shaft and fabric. Compared to the current manual fabric placement process, this structure offers the following technical advantages: 1. High quality stability: This structure solves the problem of difficulty in accurately controlling the tension and uniformity of the fabric when manually applying it. When applying the fabric, the lower end of the fabric is clamped first, which can avoid defects such as fabric wrinkles, shifts or local looseness during the application process. 2. High production efficiency: The entire fabric application process is automated, and the operator only needs to place the roller and the fabric, which further improves production efficiency. 3. Low labor intensity: The entire fabric application process does not require fine manual skills and does not require a high level of proficiency from the operators; 4. Product consistency can be guaranteed: Since the entire fabric covering operation is automated, the manual labor only needs to place the shaft and the fabric. During the fabric covering process, the lower end of the fabric is clamped first, and the clamping force is consistent. As a result, the quality difference between different batches of fabric covering is not significant, which further ensures the consistency of the finished liner quality and is conducive to the standardization of product quality.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
