Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring processing technology, and specifically discloses a positioning tooling for processing rubber sealing rings. Background Technology

[0002] In the batch processing of rubber sealing rings, cutting is the core step that determines the final dimensional accuracy of the product. When it is necessary to cut the vulcanized rubber ring into a sealing ring of a preset width, the rubber ring needs to be firmly fixed in the preset position by a positioning fixture. The positioning fixture is the key equipment to ensure cutting quality and production efficiency.

[0003] In existing processing methods, the positioning fixtures for the cutting process are mostly single-station designs, meaning that only one rubber ring can be fixed for cutting at a time. After cutting a sealing ring, the machine must be stopped, the finished product must be manually removed, and a new rubber ring blank must be placed in the positioning position and recalibrated. This frequent stopping and starting not only significantly extends the overall processing cycle but also makes it difficult to meet the large-scale, high-efficiency production requirements of sealing rings in industries such as automotive and hydraulics. Therefore, a positioning fixture for rubber sealing ring processing is needed to solve the above problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figures 1-4 A rubber sealing ring processing and positioning fixture includes a base 1, and a continuous positioning mechanism is provided at the upper end of the base 1.

[0024] The continuous positioning mechanism includes two left and right support columns 5 rotatably connected to the upper end of the base 1. Gears 6 are fixedly connected to the outer walls of the two support columns 5. A vertical plate 2 is fixedly connected to the upper end of the base 1. An electric push rod 3 is installed on the outer wall of the vertical plate 2. The output end of the electric push rod 3 passes through the vertical plate 2 and is fixedly connected to a rack 4 that meshes with the two gears 6. A frame 8 and a column 9 are fixedly connected to the upper ends of the two support columns 5 respectively. Multiple evenly distributed positioning rods 10 are rotatably connected to both ends of the frame 8. Multiple evenly distributed support rods 7 are fixedly connected to both ends of the outer wall of the column 9.

[0025] The outer wall of the frame 8 is provided with a pushing mechanism, which includes a fixed plate 14 fixedly connected to the upper end of the frame 8. The left and right ends of the fixed plate 14 are each equipped with a second electric push rod 15. The left and right ends of the frame 8 are each provided with a push plate 16 sleeved on the outer wall of a plurality of positioning rods 10 on the same side. The output ends of the two second electric push rods 15 pass through the fixed plate 14 and are fixedly connected to the two push plates 16 respectively.

[0026] In this embodiment: During processing, the rubber rings to be cut are first placed on the positioning rods 10 on the left and right sides of the frame 8, respectively, and basic positioning is achieved by adhering to the inner wall of the rubber rings. At this time, the electric actuator 3 is activated, and its output end drives the rack 4 to move horizontally. The translation of the rack 4 is converted into the synchronous rotation of the two gears 6, which in turn drives the two support columns 5, the frame 8 and the column 9 to rotate in a coordinated manner. When rotated to the preset processing position, the support rod 7 on the column 9 corresponds precisely to and is tightly fitted with the positioning rod 10 on the frame 8.

[0027] Subsequently, the cutting mechanism performs cutting processing on the rubber ring in the positioning state. Once one side of the rubber ring is cut, the second electric push rod 15 on the fixed plate 14 is immediately activated. Its output end pushes the push plate 16 to move axially along the positioning rod 10, smoothly pushing the cut rubber ring off the positioning rod 10 and placing it on the outer wall of the corresponding support rod 7, completing automatic unloading. Then, the push plate 16 resets under the drive of the second electric push rod 15. Immediately afterwards, the electric push rod 3 drives the rack 4 to move in the opposite direction, causing the frame 8 and column 9 to rotate 180 degrees. Since the outer wall of the positioning rod 10 on the other side of the frame 8 has a pre-fitted rubber ring to be cut, it can directly enter the next round of positioning and cutting process, thus achieving continuous and uninterrupted positioning processing, significantly reducing equipment downtime and significantly improving production efficiency.

[0028] As a technical optimization of this utility model, a second sprocket 11 is fixedly connected to one end of a plurality of positioning rods 10 located on the inner wall of the frame 8. Motors 12 are installed at both ends of the frame 8. The output ends of the two motors 12 pass through the frame 8 and are fixedly connected to a first sprocket 13. The plurality of second sprockets 11 located on the same side and the corresponding first sprockets 13 are connected by chain meshing.

[0029] In this embodiment: the motor 12 drives the first sprocket 13 to rotate, and with the help of the chain transmission, it can drive multiple second sprockets 11 on the same side to rotate synchronously, thereby enabling multiple positioning rods 10 to rotate synchronously. During the cutting and processing of the rubber sealing ring, the synchronous rotation of the positioning rods 10 can drive the rubber ring fitted on it to rotate together, allowing the cutting blade 22 to cut the circumference of the rubber ring evenly.

[0030] As a technical optimization of this utility model, a T-shaped slider is fixedly connected to the lower end of the rack 4, and the T-shaped slider is slidably connected to the base 1 through the T-shape.

[0031] In this embodiment, the T-shaped slider is slidably connected to the base 1 via a T-shape, which can increase the stability of the rack 4 movement.

[0032] As a technical optimization of this utility model, the multiple positioning rods 10 located on the right side are respectively attached to the multiple support rods 7 located on the left side.

[0033] In this embodiment, the multiple positioning rods 10 located on the right side are respectively attached to the multiple support rods 7 located on the left side, so that the cut rubber ring can be smoothly moved to the outer wall of the support rod 7.

[0034] As a technical optimization of this utility model, the outer walls of the multiple positioning rods 10 are all fitted with rubber sleeves.

[0035] In this embodiment, the surface of the rubber sleeve has a certain roughness, which can increase the friction between it and the inner wall of the rubber sealing ring. During the process of the positioning rod 10 driving the sealing ring to rotate or the push plate 16 pushing the sealing ring to move, the relative sliding between the sealing ring and the positioning rod 10 can be reduced, ensuring that the two move synchronously, and further ensuring the stability of the cutting process and the smoothness of the unloading process.

[0036] As a technical optimization of this utility model, the ends of the multiple support rods 7 away from the column 9 are tapered.

[0037] In this embodiment, the ends of the multiple support rods 7 away from the column 9 are tapered, which can prevent jamming during the synchronous rotation of the support rods 7 and the positioning rods 10.

[0038] As a technical optimization of this utility model, a rectangular plate 17 is fixedly connected to the upper end of the base 1. A third electric push rod 18 is installed on the outer wall of the rectangular plate 17. The output end of the third electric push rod 18 passes through the rectangular plate 17 and is fixedly connected to an auxiliary plate 19. A fourth electric push rod 20 is installed at the rear end of the auxiliary plate 19. The output end of the fourth electric push rod 20 passes through the auxiliary plate 19 and is fixedly connected to an mounting plate 21. A cutting blade 22 is installed on the outer wall of the mounting plate 21.

[0039] In this embodiment: the output end of the third electric actuator 18 drives the auxiliary plate 19 and subsequent components to move in the horizontal direction, which can adjust the horizontal distance between the cutting blade 22 and the positioned rubber sealing ring. The fourth electric actuator 20 can push the mounting plate 21 and the cutting blade 22 to move in the front and back direction, so as to achieve precise control of the cutting depth.

[0040] The working principle and usage process of this utility model are as follows: During processing, the rubber rings to be cut are first placed on the positioning rods 10 on the left and right sides of the frame 8. The positioning rods 10 provide initial support for the rubber rings through their own structure, and basic positioning is achieved by adhering to the inner wall of the rubber rings. At this time, the electric actuator 3 is activated, and its output end drives the rack 4 to move horizontally. Since the rack 4 is engaged with the gears 6 on the outer wall of the two support columns 5, the translation of the rack 4 is converted into the synchronous rotation of the two gears 6, which in turn drives the two support columns 5, the frame 8, and the column 9 to rotate in a coordinated manner. When the rotation reaches the preset processing position, the support rod 7 on the column 9 corresponds precisely to and adheres to the positioning rod 10 on the frame 8.

[0041] Subsequently, the cutting mechanism performs cutting processing on the rubber ring in the positioning state. Once one side of the rubber ring is cut, the second electric push rod 15 on the fixed plate 14 is immediately activated. Its output end pushes the push plate 16 to move axially along the positioning rod 10, smoothly pushing the cut rubber ring off the positioning rod 10 and placing it on the outer wall of the corresponding support rod 7, completing automatic unloading. Then, the push plate 16 resets under the drive of the second electric push rod 15. Immediately afterwards, the electric push rod 3 drives the rack 4 to move in the opposite direction, causing the frame 8 and column 9 to rotate 180 degrees. Since the outer wall of the positioning rod 10 on the other side of the frame 8 has a pre-fitted rubber ring to be cut, it can directly enter the next round of positioning and cutting process, thus achieving continuous and uninterrupted positioning processing, significantly reducing equipment downtime and significantly improving production efficiency.

[0042] Simultaneously, when the motor 12 on the frame 8 is working, its output end drives the first sprocket 13 to rotate. The first sprocket 13 drives multiple second sprockets 11 on the same side to rotate via a chain, thereby causing multiple positioning rods 10 to rotate synchronously, cooperating with the cutting process to ensure uniform cutting. The cutting assembly, consisting of the rectangular plate 17, the third electric push rod 18, the auxiliary plate 19, the fourth electric push rod 20, the mounting plate 21, and the cutting blade 22 on the base 1, can adjust the position of the cutting blade 22 under the drive of the third electric push rod 18 and the fourth electric push rod 20 to complete the precise cutting of the rubber ring.
