Description

Technical Field

[0001] This application relates to the technical field of engine assembly, and in particular to a quick-change structure for press-fitting front and rear oil seals of an engine. Background Technology

[0002] As a critical sealing component ensuring the normal operation of an engine, the quality of its press-fitting directly affects the engine's sealing performance and service life. Improper press-fitting of the oil seal can easily lead to malfunctions such as oil leaks, which not only affect the engine's working efficiency but may also cause serious mechanical damage.

[0003] Currently, the pressing process for oil seals in existing engines typically involves first positioning the seal using a locating sleeve, and then completing the pressing operation with the aid of a push sleeve. However, during this process, manual operation makes it difficult to precisely control the magnitude and direction of the applied force, easily leading to uneven force distribution. While this uneven force distribution may seem to cause only minor damage to the oil seal, during the engine's subsequent long-term high-speed operation, these minor damages will be amplified, eventually damaging the sealing structure of the oil seal and ultimately causing oil seal failure. Oil seal failure not only increases engine maintenance costs and downtime but may also trigger a series of chain reactions due to oil leaks, posing a serious threat to the overall performance and operational safety of the engine. Therefore, to solve the above problems, this application provides a quick-change structure for pressing front and rear oil seals in engines. Utility Model Content

[0004] To address the aforementioned issues, this application provides a quick-change structure for press-fitting front and rear oil seals of an engine.

[0005] This application provides a quick-change structure for pressing and installing front and rear oil seals of an engine, including a sliding block that cooperates with an external platform, a positioning sleeve for placing the oil seal, and a push sleeve for pushing the oil seal. The outer sides of the positioning sleeve and the push sleeve are provided with a primary pushing structure for pushing the entire structure, and the inner side of the primary pushing structure is provided with a secondary pushing structure for independently pushing the push sleeve.

[0006] The device is positioned by a primary pushing structure, which pushes the oil seal to the required installation location. Then, a secondary pushing structure pushes the sleeve independently. Because it is located at the center of the sleeve, the force on each part of the sleeve is even, thus ensuring the quality of the oil seal installation.

[0007] Preferably, the primary pushing structure includes a support plate fixed to the positioning sleeve, and a hydraulic cylinder is provided between the support plate and the sliding block to control the distance between them.

[0008] Preferably, a column is fixedly provided between the positioning sleeve and the support plate.

[0009] Preferably, the secondary pushing structure includes a support ring disposed at the top of the push sleeve, and a bracket is fixedly disposed at the middle position of the support ring.

[0010] Preferably, the secondary pushing structure further includes a second hydraulic cylinder fixed below the support plate, and the output end of the second hydraulic cylinder is connected to the bracket.

[0011] Preferably, a partition is fixedly connected to the middle section of the column, and a CCD camera structure is fixedly installed on the partition.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The device is positioned by a primary pushing structure, which pushes the oil seal to the required installation location. Then, a secondary pushing structure pushes the sleeve independently. Because it is located at the center of the sleeve, the force on each part of the sleeve is even, thus ensuring the quality of the oil seal installation. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0019] Example 1:

[0020] A quick-change structure for press-fitting front and rear oil seals of an engine, referring to Figure 1 - Figure 3The system includes a sliding block 1 that cooperates with an external platform, which has X and Y axis adjustment capabilities. This architecture is very common and is not an improvement of this application, so it is not further disclosed in this application. The sliding block 1 is provided with a threaded pair that connects to a lead screw in this architecture. It also includes a positioning sleeve 9 for placing an oil seal and a push sleeve 8 for pushing the oil seal. The outer sides of the positioning sleeve 9 and the push sleeve 8 are provided with a primary pushing structure for pushing them as a whole, and the inner side of the primary pushing structure is provided with a secondary pushing structure for independently pushing the push sleeve 8.

[0021] The device is pushed to its position by a primary pushing structure, so that the oil seal reaches the required installation position. Then, the secondary pushing structure pushes the push sleeve 8 independently. Since it is located at the center of the push sleeve 8, the force on each part of the push sleeve 8 is even, thereby ensuring the quality of oil seal installation.

[0022] The push structure includes a support plate 3 fixed to the positioning sleeve 9. A hydraulic cylinder 2 is set between the support plate 3 and the sliding block 1 to control the distance between them. The hydraulic cylinder 2 extends and retracts to realize the transmission of the position of the support plate 3. Since the position between the support plate 3 and the positioning sleeve 9 is fixed, the positioning sleeve 9 will move accordingly to change the overall height of the device.

[0023] A column 4 is fixedly installed between the positioning sleeve 9 and the support plate 3. The secondary pushing structure includes a support ring 6 set at the top of the push sleeve 8, and a bracket 7 fixedly installed in the middle of the support ring 6. The bracket 7 has a cross-shaped structure as shown in the figure, which ensures that the force can be transmitted relatively evenly, while avoiding contact with the column 4. The secondary pushing structure also includes a second hydraulic cylinder 5 fixed below the support plate 3, and the output end of the second hydraulic cylinder 5 is connected to the bracket 7.

[0024] A partition 10 is fixedly connected to the middle section of the column 4, and a CCD camera structure 11 is fixedly installed on the partition 10. The CCD camera structure 11 is used to observe the alignment of the oil seal, thereby facilitating the docking between the positioning sleeve 9 and the engine.

[0025] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a press-fit quick-change structure for front and rear oil seals of an engine provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
