A shaft package for use with a press-fitting machine

Abstract

This utility model discloses a shaft seal press-fitting machine, relating to the field of press-fitting machine technology. The press-fitting machine includes a frame, from bottom to top, on which a lifting and positioning mechanism, a symmetrically arranged oiling mechanism, and a press-fitting mechanism are respectively installed. When the lifting platform rises to the middle position of the oiling mechanism, an electric cylinder drives the motor housing to move downwards, descending to be flush with the fuel injector. At this time, two symmetrically arranged cylinders push the fixing plates towards the shaft seal. When the two fixing plates move to near both sides of the shaft seal, the fuel injector applies oil to the shaft seal through the fuel line. A rotating motor drives the shaft seal on the magnetic suction cup to rotate, allowing the shaft seal to contact the oil sprayed from the fuel injector in all directions during the oiling process. Compared to static oiling, the rotating state allows for more even oiling of all parts of the shaft seal, avoiding dead zones or uneven thickness, thereby improving the lubrication performance and sealing effect of the shaft seal.

Description

Technical Field

[0001] This utility model specifically relates to the field of press-fitting machine technology, and more specifically to a press-fitting machine for shaft sealing. Background Technology

[0002] In industrial production, shaft seals, as a key component, are widely used in various mechanical equipment. Their function is to prevent leakage of liquids or gases inside the machine, while also preventing external impurities from entering the equipment, ensuring its normal operation and service life. With the acceleration of industrial modernization, especially the rapid development of industries such as automobile manufacturing, aerospace, and precision machining, extremely high demands are placed on the precision and efficiency of shaft seal assembly.

[0003] In traditional shaft seal assembly, manual operation is the primary method. Assembly workers must manually place the shaft seal in the predetermined position by visual inspection before pressing it in. This method has several drawbacks: Firstly, manual placement of the shaft seal requires frequent visual adjustments to ensure accurate positioning, which is time-consuming and inaccurate. If the shaft seal is misaligned, it not only increases the difficulty of subsequent processes but may also waste valuable production materials, leading to increased production costs. Secondly, in the pressing stage, the control of assembly pressure relies entirely on the worker's experience. Insufficient pressure results in an insecure shaft seal assembly, which can easily lead to leakage during equipment operation; excessive pressure may damage the shaft seal, affecting product quality and reducing the reliability and stability of the equipment.

[0004] Chinese Patent Publication No. CN 218533455 (U-type) discloses a shaft seal pressing device for an automotive electric compressor. The device includes a base platform with a shaft seal positioning fixture on the platform for positioning the shaft seal. Above the positioning fixture is a shaft seal cover positioning fixture for positioning the shaft seal cover. A guide mechanism connects the two fixtures. The device also includes a pressing mechanism that drives the shaft seal cover positioning fixture towards the positioning fixture, pressing the shaft seal onto the positioning fixture into the shaft seal cover. This invention features a simple structure, easy operation, and low cost. Even workers unfamiliar with shaft seal pressing can quickly learn and successfully complete the process. It effectively avoids reduced production efficiency and product quality issues caused by worker turnover and replacement, making it highly valuable for mass production in compressor assembly lines.

[0005] The aforementioned shaft seal press-fitting device is very inconvenient during press-fitting. Since the press head needs to be manually pressed through the operating handle, the problem of low efficiency becomes more and more prominent when facing large-scale production tasks, making it difficult to meet the high-efficiency and high-quality production needs of modern industry. Utility Model Content

[0006] The purpose of this utility model is to provide a shaft sealing press machine. By installing a lifting and positioning mechanism, an oiling mechanism and a pressing mechanism, the press machine can automate the pressing process while improving pressing efficiency and multifunctionality, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A shaft package for use with a press-fitting machine, comprising:

[0009] The frame is equipped with a lifting and positioning mechanism, a symmetrically arranged oiling mechanism, and a pressing mechanism from bottom to top.

[0010] The oiling mechanism includes an L-plate, on which a cylinder is mounted, and a slide rail is symmetrically arranged inside one side. The slide rail is slidably connected to a slide groove, which is symmetrically arranged on one side of a connecting plate. The bottom of the connecting plate is connected to the end of the cylinder. A cylinder is mounted on the upper end of the connecting plate, and a fixing plate is provided at the end of the cylinder. An oil nozzle is mounted in the middle of the fixing plate.

[0011] As a further technical solution of this utility model, the L-plate is symmetrically arranged on both sides of the inside of the mounting frame, and a base plate is provided at each of the four corners of the bottom of the mounting frame. The inner side of the mounting frame is also connected to the bottom plate, the H-plate and the top plate in sequence from bottom to top.

[0012] As a further technical solution of this utility model, a bottom lifting cylinder is installed in the middle position of the H plate, and slide rails are symmetrically installed on the upper surface. A sliding rod is provided in the slide rail, and a fixing ring is provided at the lower end of the sliding rod.

[0013] As a further technical solution of this utility model, a lifting platform is installed at the upper end of the lifting cylinder and the symmetrically arranged sliding rod. The lifting platform has a semi-enclosed design and is symmetrically arranged with fixing blocks inside. Each fixing block has a double cylinder installed at its upper end, and the ends of the double cylinders are provided with clamping plates.

[0014] As a further technical solution of this utility model, an electric cylinder is installed at the upper end of the top plate, and the end of the electric cylinder passes through the top plate and is fixedly connected to the motor box at the bottom. A rotary motor is installed inside the motor box, and the rotary motor is connected to the magnetic suction cup at the bottom through the bearing inside the motor box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the equipment to be assembled, which requires pressing the shaft seal, is first placed on the lifting platform. The equipment is clamped and fixed by the symmetrically installed double cylinders inside the lifting platform. The clamping of the equipment by the double cylinders can firmly fix it on the lifting platform, ensuring that it will not shift or shake during the pressing process, thereby ensuring the accuracy and quality of the pressing. Then, the lifting platform is raised by the bottom lifting cylinder until it reaches the middle position of the oiling mechanism. The bottom lifting cylinder stops rising. Different shaft seals and equipment to be assembled may have different heights. The lifting cylinder can adjust the height of the lifting platform according to actual needs, which is convenient for workers to operate, reduces the extent of bending or reaching by workers, and reduces labor intensity.

[0017] 2. In this utility model, when the lifting platform rises to the middle position of the oiling mechanism, the electric cylinder drives the motor box to move downwards until it is flush with the fuel injector. At this time, the two cylinders symmetrically arranged push the fixing plate to move towards the shaft seal. When the two fixing plates move to the vicinity of both sides of the shaft seal, the fuel injector applies oil to the shaft seal through the fuel line. The rotating motor drives the shaft seal on the magnetic suction cup to rotate, so that the shaft seal can come into contact with the oil sprayed by the fuel injector in all directions during the oiling process. Compared with static oiling, the shaft seal can be coated with oil more evenly in the rotating state, avoiding the occurrence of oiling dead corners or uneven thickness, thereby improving the lubrication performance and sealing effect of the shaft seal.

[0018] 3. In this utility model, after the oiling process is completed, the rotary motor stops rotating, and the electric cylinder continues to drive the magnetic chuck and shaft seal to move downwards until the shaft seal is pressed into the assembly equipment. The entire process is controlled by the electric cylinder and the rotary motor automated components, without the need for manual intervention in the pressing operation. This not only reduces the workload and labor intensity of manual operation, but also reduces the impact of human factors on the pressing quality, and improves the stability and reliability of the production process. At the same time, the use of the magnetic chuck to magnetically attract the shaft seal can firmly fix the shaft seal, ensuring that the shaft seal will not shift or fall off during the pressing process.

[0019] 4. In this utility model, the height of the shaft seal position may vary greatly for different types and specifications of equipment to be assembled. When the shaft seal position is too high, the connecting plate can be moved upward by the first cylinder. The connecting plate slides with the slide rail on the side of the L-plate through the slide groove on one side, thereby driving the second cylinder to move upward, so that the oil nozzle can rise to a suitable height for oiling. This greatly enhances the versatility of the press machine for different equipment, eliminates the need to equip equipment with special oiling devices for equipment with shaft seals of different heights, reduces equipment costs, and improves the adaptability of the press machine.

[0033] 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.

[0034] Please see Figure 1-8In this embodiment of the utility model, a shaft packaging press machine includes a frame 1, on which a lifting and positioning mechanism 2, an oiling mechanism 4 and a press mechanism 3 are respectively installed from bottom to top.

[0035] The oiling mechanism 4 includes an L-plate 41, on which a cylinder 43 is mounted. A slide rail 42 is symmetrically arranged inside one side of the L-plate 41. The slide rail 42 is slidably connected to a slide groove 44. The slide groove 44 is symmetrically arranged on one side of a connecting plate 45. The bottom of the connecting plate 45 is connected to the end of the cylinder 43. A cylinder 46 is mounted on the upper end of the connecting plate 45. A fixing plate 47 is provided at the end of the cylinder 46. An oil nozzle 48 is mounted in the middle of the fixing plate 47.

[0036] By adopting the above technical solution, when the lifting platform 25 rises to the middle position of the oiling mechanism 4, the electric cylinder 31 drives the motor box 32 to move downwards, descending to be flush with the fuel injector 48. At this time, the symmetrically arranged cylinders 46 push the fixing plate 47 to move towards the shaft seal. When the two fixing plates 47 move to the vicinity of both sides of the shaft seal, the fuel injector 48 applies oil to the shaft seal through the fuel line. The rotating motor 33 drives the shaft seal on the magnetic chuck 34 to rotate, so that the shaft seal can come into contact with the oil sprayed by the fuel injector 48 in all directions during the oiling process. Compared with static oiling, the shaft seal can be coated with oil more evenly in the rotating state, avoiding oiling dead corners or uneven thickness, thereby improving the lubrication performance and sealing effect of the shaft seal.

[0037] Different types and specifications of equipment to be assembled may have significant differences in the height of their shaft seal positions. When the shaft seal position is too high, the connecting plate 45 can be moved upward by the cylinder 43. The connecting plate 45 slides with the slide rail 42 on the side of the L plate 41 through the slide groove 44 on one side, thereby driving the cylinder 46 to move upward, so that the oil nozzle 48 can rise to a suitable height for oiling. This greatly enhances the versatility of the press machine for different equipment, eliminating the need to equip equipment with shaft seals of different heights with special oiling devices, reducing equipment costs and improving the adaptability of the press machine.

[0038] In this embodiment, the L plate 41 is symmetrically arranged on both sides of the inside of the mounting frame 12. The four corners of the bottom of the mounting frame 12 are each provided with a base plate 11. The inner side of the mounting frame 12 is also connected to the bottom plate 13, the H plate 14 and the top plate 15 from bottom to top.

[0039] A bottom lifting cylinder 21 is installed in the middle of the H plate 14, and slide rails 22 are symmetrically installed on the upper surface. A sliding rod 23 is provided in the slide rail 22, and a fixing ring 24 is provided at the lower end of the sliding rod 23.

[0040] The upper ends of the lifting cylinder 21 and the symmetrically arranged sliding rod 23 are equipped with a lifting platform 25. The lifting platform 25 has a semi-enclosed design and is equipped with symmetrically arranged fixing blocks 26 inside. Each fixing block 26 is equipped with a double cylinder 27 at its upper end, and the ends of the double cylinders 27 are equipped with clamping plates 28.

[0041] By adopting the above technical solution, during use, the equipment to be assembled, which requires pressing the shaft seal, is first placed on the lifting platform 25. The equipment is clamped and fixed by the symmetrically installed double cylinders 27 inside the lifting platform 25. The clamping of the equipment by the double cylinders 27 can firmly fix it on the lifting platform 25, ensuring that it will not shift or shake during the pressing process, thereby ensuring the accuracy and quality of pressing. Then, the lifting platform 25 is raised by the bottom lifting cylinder 21 until it reaches the middle position of the oiling mechanism 4. The bottom lifting cylinder 21 then stops rising. Different shaft seals and equipment to be assembled may have different heights. The lifting cylinders can adjust the height of the lifting platform 25 according to actual needs, which is convenient for workers to operate, reduces the extent to which workers bend over or reach out, and reduces labor intensity.

[0042] In this embodiment, an electric cylinder 31 is installed at the upper end of the top plate 15. The end of the electric cylinder 31 passes through the top plate 15 and is fixedly connected to the motor box 32 at the bottom. A rotary motor 33 is installed inside the motor box 32. The rotary motor 33 is connected to the magnetic suction cup 34 at the bottom through the bearing inside the motor box 32.

[0043] By adopting the above technical solution, after the oiling process is completed, the rotary motor 33 stops rotating, and the electric cylinder 31 continues to drive the magnetic chuck 34 and the shaft seal to move downwards until the shaft seal is pressed into the assembly equipment. The entire process is controlled by the electric cylinder 31 and the rotary motor 33 automated components, without the need for manual intervention in the pressing operation. This not only reduces the workload and labor intensity of manual operation, but also reduces the impact of human factors on the pressing quality, and improves the stability and reliability of the production process. At the same time, the magnetic chuck 34 can magnetically attract the shaft seal, which can firmly fix the shaft seal and ensure that the shaft seal will not be displaced or fall off during the pressing process.

[0044] The working principle of this utility model is as follows: First, the equipment to be assembled, which requires pressing of the shaft seal, is placed on the lifting platform 25. The equipment is clamped and fixed by symmetrically installed double cylinders 27 inside the lifting platform 25. This clamping of the equipment by the double cylinders 27 ensures it is firmly fixed to the lifting platform 25, preventing displacement or shaking during the pressing process, thus guaranteeing the accuracy and quality of the pressing. Then, the bottom lifting cylinder 21 drives the lifting platform 25 to rise to the middle position of the oiling mechanism 4, at which point the bottom lifting cylinder 21 stops rising. Different shaft seals and equipment to be assembled may have different heights; the lifting cylinders allow the height of the lifting platform 25 to be adjusted according to actual needs, facilitating worker operation, reducing the bending or reaching distance, and lowering labor intensity.

[0045] When the lifting platform 25 rises to the middle position of the oiling mechanism 4, the electric cylinder 31 drives the motor housing 32 to move downwards until it is flush with the fuel injector 48. At this time, the symmetrically arranged cylinders 46 push the fixing plate 47 to move towards the shaft seal. When the two fixing plates 47 move to the vicinity of both sides of the shaft seal, the fuel injector 48 applies oil to the shaft seal through the fuel line. The rotary motor 33 drives the shaft seal on the magnetic chuck 34 to rotate, so that the shaft seal can come into contact with the oil sprayed by the fuel injector 48 in all directions during the oiling process. Compared with static oiling, the shaft seal can be coated with oil more evenly in the rotating state, avoiding oiling dead corners or uneven thickness, thereby improving the lubrication performance and sealing effect of the shaft seal.

[0046] After the oiling process is completed, the rotary motor 33 stops rotating, and the electric cylinder 31 continues to drive the magnetic chuck 34 and the shaft seal to move downwards until the shaft seal is pressed into the assembly equipment. The entire process is controlled by the electric cylinder 31 and the rotary motor 33, which are automated components. No manual intervention is required for the pressing operation. This not only reduces the workload and labor intensity of manual operation, but also reduces the impact of human factors on the pressing quality, and improves the stability and reliability of the production process. At the same time, the magnetic chuck 34 can firmly fix the shaft seal, ensuring that the shaft seal will not shift or fall off during the pressing process.

[0047] Different types and specifications of equipment to be assembled may have significant differences in the height of their shaft seal positions. When the shaft seal position is too high, the connecting plate 45 can be moved upward by the cylinder 43. The connecting plate 45 slides with the slide rail 42 on the side of the L plate 41 through the slide groove 44 on one side, thereby driving the cylinder 46 to move upward, so that the oil nozzle 48 can rise to a suitable height for oiling. This greatly enhances the versatility of the press machine for different equipment, eliminating the need to equip equipment with shaft seals of different heights with special oiling devices, reducing equipment costs and improving the adaptability of the press machine.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
