Description

Technical Field

[0001] This utility model relates to the field of oil seal and flange press-fitting technology, and in particular to a through shaft oil seal and flange press-fitting device. Background Technology

[0002] The oil seal and flange press-fitting process of the through shaft must ensure sealing performance and coaxiality. The flange press-fitting requires control of the interference fit. It should be slowly advanced by hydraulic or mechanical pressure, and the press-fitting force and displacement curve should be monitored in real time to ensure that it fits the shaft shoulder without gap after being in place. After pressing, check the integrity of the oil seal lip and the perpendicularity of the flange. If necessary, perform an airtightness test. Pay attention to dust prevention throughout the process to avoid secondary damage.

[0003] In the field of mechanical assembly, the pressing of oil seals and flanges on through shafts is a key process to ensure sealing performance and transmission accuracy. Traditional pressing processes usually rely on manual placement of oil seals, requiring operators to manually align the through shaft. However, due to the precision of the oil seal structure (such as the lip needing to face the sealing side), manual alignment is prone to deviation, resulting in poor sealing or lip damage after pressing, affecting product reliability and lifespan.

[0004] Based on the aforementioned technologies, the applicant believes that existing press-fitting equipment often lacks an effective clamping and positioning mechanism for the through shaft. During the press-fitting process, the shaft is prone to offset or tilting, resulting in poor fit between the flange and the shaft shoulder, causing assembly gaps or excessive coaxiality. Although some equipment adopts a simple guide structure, it is still difficult to guarantee the stability and consistency of the press-fitting process, increasing the rework rate and the risk of scrap. In response to the above problems, we have launched a press-fitting equipment for through shaft oil seals and flanges. Utility Model Content

[0005] This utility model discloses a through-shaft oil seal and flange pressing equipment, which aims to solve the technical problems that existing pressing equipment often lacks an effective clamping and positioning mechanism for the through-shaft, making the shaft prone to displacement or tilting during the pressing process, resulting in poor fit between the flange and the shaft shoulder, and causing assembly gaps or excessive coaxiality. Although some equipment adopts a simple guide structure, it is still difficult to guarantee the stability and consistency of the pressing process, increasing the rework rate and the risk of scrap.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The pressing mechanism includes a clamping assembly, a pressing assembly, and a dispensing assembly, which cooperate with each other. The clamping assembly includes a placement groove, which is opened on one side of the top of the placement base. A positioning plate is fixedly connected inside the placement base, and sliding columns are symmetrically slidably connected inside the positioning plate.

The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The through-shaft oil seal and flange press-fitting equipment disclosed in this utility model is mainly used in the scenario of oil seal and flange press-fitting.

[0030] Reference Figures 1-5A through-shaft oil seal and flange pressing device includes a pressing base 1, a placement base 2 fixedly connected to the top of the pressing base 1, and a pressing mechanism on the top of the pressing base 1. The pressing mechanism includes a clamping component, a pressing component, and a dispensing component, which cooperate with each other. The clamping component includes a placement groove 31, which is opened on one side of the top of the placement base 2. A positioning plate 32 is fixedly connected inside the placement base 2. Sliding columns 33 are symmetrically slidably connected inside the positioning plate 32. A limit plate 34 is fixedly connected to one end of each of the two sliding columns 33. A spring 35 is sleeved on the outer side of each of the two sliding columns 33. A clamping head 36 is fixedly connected to the other end of each of the two sliding columns 33. Sliding grooves 37 are symmetrically opened on both sides of the inner wall of the placement base 2. Sliding sleeves 38 are symmetrically slidably connected to the outer side of the placement base 2. Both sliding sleeves 38 are fixedly connected to the clamping head 36. The pressing assembly includes a cylinder 41, which is fixedly connected to the top of the pressing base 1. Slide rods 44 are symmetrically slidably connected to the top of the pressing base 1. A blocking plate 45 is fixedly connected to the top of each slide rod 44. A pressing column 43 is fixedly connected to the telescopic end of the cylinder 41. A stabilizing plate 42 is fixedly connected to the outside of the telescopic end of the cylinder 41. The top of the stabilizing plate 42 is fixedly connected to the bottom of the slide rod 44. The dispensing assembly includes fixed posts 61, which are symmetrically fixedly connected to the bottom of the inner wall of the press base 1. A connecting plate 62 is fixedly connected to the top of the two fixed posts 61. An installation sleeve 63 is fixedly connected to the top of the connecting plate 62. The outer wall of the installation sleeve 63 is provided with an external thread 68. The top of the installation sleeve 63 is provided with a dispensing cylinder 64. An internal thread groove 66 is opened at the bottom of the inner wall of the dispensing cylinder 64. The internal thread groove 66 and the external thread 68 mesh with each other. A material hopper 65 is fixedly connected to the top of the dispensing cylinder 64. A clearance groove 69 is symmetrically opened on the outer side of the dispensing cylinder 64. An oil seal body 67 is placed inside the dispensing cylinder 64.

[0031] In this embodiment: the through shaft to be pressed is placed horizontally in the placement groove 31. The two clamping heads 36 in the clamping assembly automatically move towards the center under the elastic force of the spring 35. Precise clamping is achieved through the guidance of the limiting plate 34 and the sliding column 33, ensuring that the through shaft is in a stable centered position. The material hopper 65 of the feeding assembly guides the oil seal body 67 into the feeding cylinder 64. The feeding cylinder 64 is easy to disassemble and assemble through the cooperation of the internal thread groove 66 and the external thread 68, so that the oil seal is accurately aligned with the end of the through shaft. When the pressing program is started, the controller 5 controls the cylinder 41 to move and push the pressing column 43 down. At the same time, the guide structure composed of the stabilizing plate 42 and the sliding rod 44 ensures that the pressing process is vertical and stable and avoids deflection. The pressing force is limited by the blocking plate 45 to prevent overpressure damage to the oil seal lip. Through the set pressing mechanism, the functions of automatic centering, precise clamping and controllable pressing are realized, so as to improve the pressing quality and efficiency of oil seal and flange, reduce human error, improve the level of assembly automation, and have a simple structure and strong practicality.

[0032] In the above technical solution, considering that existing pressing equipment often lacks an effective clamping and positioning mechanism for the through shaft, the shaft is prone to displacement or tilting during the pressing process, resulting in poor fit between the flange and the shaft shoulder, causing assembly gaps or excessive coaxiality. Although some equipment adopts a simple guiding structure, it is still difficult to guarantee the stability and consistency of the pressing process, increasing the rework rate and the risk of scrap. To solve these problems, the specific operation is as follows:

[0033] Reference Figures 1-5 In a preferred embodiment, fixing plates 7 are fixedly connected at equal intervals on both sides of the pressing base 1, and mounting holes 8 are provided inside the fixing plates 7. A pulling frame 39 is fixedly connected to the top of the clamping head 36. A controller 5 is fixedly connected to the outside of the pressing base 1, and the cylinder 41 is electrically connected to the controller 5.

[0034] In this embodiment: the fixing plate 7 and mounting holes 8 facilitate the overall fixation of the equipment, enhance the stability of the pressing process, reduce vibration interference, and ensure assembly quality. The pull bracket 39 of the clamping head 36 facilitates manual adjustment of the clamping position, improves operational flexibility, and adapts to through shafts of different sizes. The controller 5 is electrically connected to the cylinder 41 to achieve precise control of the pressing force, avoid excessive or insufficient pressure, and improve the level of automation and assembly reliability.

[0035] Working principle: First, the operator places the through shaft to be pressed horizontally in the placement groove 31. The two clamping heads 36 in the clamping assembly automatically move towards the center under the elastic force of the spring 35. Precise clamping is achieved through the guidance of the limiting plate 34 and the sliding column 33, ensuring that the through shaft is in a stable centered position. The material hopper 65 of the feeding assembly guides the oil seal body 67 into the feeding cylinder 64. The feeding cylinder 64 is easy to disassemble and assemble through the cooperation of the internal thread groove 66 and the external thread 68, so that the oil seal is accurately aligned with the end of the through shaft. When the pressing program is started, the controller 5 controls the cylinder 41 to operate. The pressing column 43 is pushed down, while the guide structure composed of the stabilizing plate 42 and the slide rod 44 ensures vertical stability during the pressing process and avoids skewing. The pressing force is limited by the blocking plate 45 to prevent overpressure damage to the oil seal lip. During the pressing process, the sliding sleeve 38 slides along the sliding groove 37 to maintain the stable clamping state of the clamping head 36 and prevent the through shaft from shifting. After the pressing is completed, the operator can manually release the clamping head 36 by pulling the frame 39 and take out the assembled workpiece. The whole process realizes automatic centering, precise positioning and controllable pressing of the oil seal and flange, which significantly improves the assembly quality and efficiency.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
