Description

Technical Field

[0001] This utility model relates to the field of oil seal processing equipment, specifically an oil seal processing positioning mechanism. Background Technology

[0002] An oil seal is a mechanical component used in the machinery field to seal lubricating oil, mainly to prevent lubricating oil from leaking out of transmission components.

[0003] Oil seals are an indispensable and important component in various types of machinery, playing a role in isolation, lubrication, and prevention of leakage. The selection of materials, the suitability of types, and the correctness of installation are all crucial to the normal operation of machinery.

[0004] Oil seals are mostly ring-shaped. Some oil seals require grinding or cutting on their outer side during processing. This necessitates clamping and positioning the oil seals to facilitate subsequent processing. However, since both the inner and outer sides of the oil seals need to be processed, existing clamping and positioning devices cannot switch between inner and outer clamping, reducing the practicality of the positioning devices. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an oil seal processing positioning mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for processing oil seal parts, including a fixed platform, a motor fixedly mounted on one side of the fixed platform, a rotating shaft fixedly mounted at the output end of the motor, a hollow disk fixedly mounted on one side of the rotating shaft, a groove formed inside the rotating shaft, a through hole formed on the outer side of the rotating shaft, a plurality of hollow rods evenly fixedly mounted on the outer side of the hollow disk, a movable rod slidably mounted inside the hollow rod, a clamping rod fixedly mounted on the outer side of the movable rod, and an oil injection mechanism for conveniently injecting hydraulic oil into the hollow rods, wherein the mechanism is used... During operation, oil is injected into the tank through the perforation via the oil injection mechanism, allowing hydraulic oil to enter the hollow disc. This causes the movable rod to move along the inside of the hollow rod, which in turn moves the clamping rod, fitting the oil seal to be processed onto the outside of the clamping rod. In this way, the oil seal can be clamped from the inside by the clamping rod. When it is necessary to clamp the oil seal from the outside, the oil seal is placed between the clamping rods, and then the injected hydraulic oil is sucked out by the oil injection mechanism. At this time, the movable rod moves along the inside of the hollow rod towards the hollow disc under negative pressure until the oil seal is clamped and fixed from the outside.

[0007] Preferably, the oil injection mechanism includes an oil tank, an electric push rod, a pressing plate, a connecting pipe, and a hollow ring. The oil tank is fixed on a fixed platform, the electric push rod is fixed to one side of the oil tank, the pressing plate is fixed to one side of the electric push rod, and the outer side of the pressing plate is in movable sealed contact with the inner wall of the oil tank. The connecting pipe is embedded and fixed at the top of the oil tank, the hollow ring is fixed to one side of the fixed platform, and the top of the connecting pipe is embedded and fixed at the bottom of the hollow ring. The rotating shaft moves through the center of the hollow ring, and the rotating shaft is in movable sealed contact with the inner wall of the hollow ring. The through hole is located inside the hollow ring. When activated, the electric push rod moves the extrusion plate inside the oil tank, squeezing the hydraulic oil inside. The hydraulic oil is then injected into the hollow ring through the connecting pipe, and then into the hollow disc through the perforation and groove. After that, it is injected into the hollow rod, thus driving the movable rod to move along the hollow rod, causing the clamping rod to expand and perform clamping work. Before use, the hollow disc, groove, hollow ring, and connecting pipe are filled with hydraulic oil. When the electric push rod resets, the hydraulic oil is drawn into the oil tank. Under negative pressure, the movable rod resets along the hollow rod, causing the clamping rod to retract and perform clamping work.

[0008] Preferably, the groove is connected to the interior of the hollow disc, the perforation is connected to the interior of the groove, and the side of the hollow rod near the hollow disc is connected to the interior of the hollow disc.

[0009] Preferably, the outer side of the movable rod and the inner sidewall of the hollow rod are in a movable sealed contact.

[0010] Preferably, the clamping rod is arc-shaped on both the side closest to the hollow disc and the side furthest from the hollow disc.

[0011] Preferably, one side of the electric push rod is movably inserted into the oil tank, and the contact position with the oil tank is a movable sealed contact.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In use, this utility model injects oil into the tank through the perforation via the oil injection mechanism, so that the hydraulic oil is injected into the hollow disc, thereby driving the movable rod to move along the inside of the hollow rod, driving the clamping rod to move, and fitting the oil seal to be processed onto the outside of the clamping rod. In this way, the oil seal can be clamped from the inside of the oil seal by the clamping rod.

[0014] 2. When it is necessary to clamp the outside of the oil seal, the oil seal is placed between the clamping rods. Then, the injected hydraulic oil is sucked out by the oil injection mechanism. At this time, the movable rod moves along the hollow rod towards the hollow plate under the action of negative pressure until the oil seal is clamped and fixed from the outside.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a positioning mechanism for processing oil seal parts, including a fixed platform 1. A motor 2 is fixed to one side of the fixed platform 1 via a mounting bracket. A rotating shaft 12 is fixed to the output end of the motor 2 via a coupling. A hollow disk 6 is welded to one side of the rotating shaft 12. A groove 14 is formed inside the rotating shaft 12, communicating with the interior of the hollow disk 6. A through hole 13 is formed on the outer side of the rotating shaft 12, communicating with the interior of the groove 14. Several hollow rods 7 are uniformly welded to the outer side of the hollow disk 6. The side of the hollow rod 7 closest to the hollow disk 6 communicates with the interior of the hollow disk 6. A movable rod 8 slides inside the hollow rod 7. The outer side of the movable rod 8 and the inner sidewall of the hollow rod 7 are in movable sealing contact. A clamping rod 9 is fixed to the outer side of the movable rod 8 by bolts. The clamping rod 9 is close to the hollow disk 6 and connected to the inner sidewall of the hollow rod 7. The hollow disc 6 is curved on one side. The fixed platform 1 has an oil injection mechanism for injecting hydraulic oil into the hollow rod 7. In use, the oil injection mechanism injects oil into the groove 14 through the through hole 13, so that the hydraulic oil is injected into the hollow disc 6. This drives the movable rod 8 to move along the inside of the hollow rod 7, which in turn drives the clamping rod 9 to move. The oil seal to be processed is then fitted onto the outside of the clamping rod 9. In this way, the oil seal can be clamped from the inside by the clamping rod 9. When it is necessary to clamp the outside of the oil seal, the oil seal is placed between the clamping rods 9. Then, the oil injection mechanism is used to draw out the injected hydraulic oil. At this time, the movable rod 8 moves along the inside of the hollow rod 7 towards the hollow disc 6 under negative pressure until the oil seal is clamped and fixed from the outside.

[0022] The oil filling mechanism includes an oil tank 3, an electric push rod 4, a pressing plate 10, a connecting pipe 11, and a hollow ring 5. The oil tank 3 is fixed to the fixed platform 1 by bolts. The electric push rod 4 is fixed to one side of the oil tank 3 by a mounting bracket. One side of the electric push rod 4 movably penetrates into the oil tank 3, and the contact position with the oil tank 3 is a movable seal contact. The pressing plate 10 is fixed to one side of the electric push rod 4 by bolts. The outer side of the pressing plate 10 is in movable seal contact with the inner wall of the oil tank 3. The connecting pipe 11 is embedded and fixed to the top of the oil tank 3. The hollow ring 5 is fixed to one side of the fixed platform 1 by bolts. The top of the connecting pipe 11 is embedded and fixed to the bottom of the hollow ring 5. The rotating shaft 12 movably passes through the center of the hollow ring 5, and the rotating shaft 12 is in movable seal contact with the inner wall of the hollow ring 5. The perforation 13 is located inside the hollow ring 5. When in use, the electric push rod 4 is activated, which drives the extrusion plate 10 to move inside the oil tank 3, extruding the hydraulic oil inside the oil tank 3. The hydraulic oil is injected into the hollow ring 5 through the connecting pipe 11, and then enters the hollow disc 6 through the perforation 13 and the groove 14. After that, it is injected into the hollow rod 7, thus driving the movable rod 8 to move along the hollow rod 7, which in turn drives the clamping rod 9 to expand and perform clamping work. At the same time, before use, the hollow disc 6, the groove 14, the hollow ring 5, and the connecting pipe 11 are filled with hydraulic oil. When the electric push rod 4 is reset, the hydraulic oil is drawn into the oil tank 3. Under the action of negative pressure, the movable rod 8 is reset along the hollow rod 7, which drives the clamping rod 9 to retract and perform clamping work.

[0023] Working principle: During use, the oil injection mechanism injects hydraulic oil into the tank 14 through the perforation 13, causing the hydraulic oil to enter the hollow disc 6. This drives the movable rod 8 to move along the inside of the hollow rod 7, which in turn moves the clamping rod 9, allowing the oil seal to be processed to be fitted onto the outside of the clamping rod 9. Thus, the clamping rod 9 can clamp the oil seal from the inside. When clamping the outside of the oil seal is required, the oil seal is placed between the clamping rods 9, and then the oil injection mechanism draws out the injected hydraulic oil. At this time, the movable rod 8 moves along the inside of the hollow rod 7 towards the hollow disc 6 under negative pressure until the oil seal is clamped and fixed from the outside. When in use... The electric push rod 4 drives the extrusion plate 10 to move inside the oil tank 3, squeezing the hydraulic oil inside the oil tank 3. The hydraulic oil is injected into the hollow ring 5 through the connecting pipe 11, and then enters the hollow disc 6 through the perforation 13 and the groove 14. After that, it is injected into the hollow rod 7, thus driving the movable rod 8 to move along the hollow rod 7, which in turn drives the clamping rod 9 to expand and perform clamping work. At the same time, before use, the hollow disc 6, the groove 14, the hollow ring 5, and the connecting pipe 11 are filled with hydraulic oil. When the electric push rod 4 resets, the hydraulic oil is drawn into the oil tank 3. Under the action of negative pressure, the movable rod 8 resets along the hollow rod 7, which drives the clamping rod 9 to retract and perform clamping work.
