Description

Technical Field

[0001] This utility model relates to the field of skeleton oil seals, and in particular to a special installation tool for skeleton oil seals. Background Technology

[0002] A skeleton oil seal is a mechanical seal widely used in rotary shaft sealing. It is composed of a metal skeleton and elastic rubber material. Its core structure includes a metal skeleton, a rubber sealing body, and a spring. During operation, the flexible lip of the oil seal is pressed tightly against the shaft surface under the action of the spring, forming a dynamic seal, which effectively prevents lubricating oil leakage and blocks external contaminants from entering.

[0003] When installing the oil seal on the skeleton, the skeleton is squeezed and installed. It is necessary to ensure that the bottom skeleton is centered on the pressure column. Positioning is mostly determined by manual placement, which has poor positioning effect and poor installation limit effect between skeletons. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a special installation tool for skeleton oil seals, which improves the convenience of lower skeleton positioning and installation and ensures the accuracy of upper skeleton installation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A special installation tool for skeleton oil seals includes:

[0007] A bottom support plate for bottom support, with multiple support rods fixedly connected to the top of the bottom support plate, an upper support plate fixedly connected to the top of each support rod, mounting slide rails fixedly connected to both sides of the top of the bottom support plate, mounting slide blocks slidably connected to the outside of each mounting slide rail, a positioning plate slidably connected to the inside of each mounting slide block, an upper push plate slidably connected to the middle of the bottom support plate, a positioning ejector column fixedly connected to the top of the upper push plate, a support column fixedly connected to the inside of the bottom support plate, and a flip-up push assembly installed on the outside of each support column for pushing and positioning the frame upwards; a push plate disassembly assembly installed at the rear end of the mounting slide block for disassembling the complete frame.

[0008] A hydraulic cylinder is fixedly connected to the top center of the upper support plate. The output end of the hydraulic cylinder is fixedly connected to a lower pressure plate. The top of the lower pressure plate is fixedly connected to multiple limit rods. The outer side of the limit rods is slidably connected to the inside of the upper support plate. A push column is fixedly connected to the bottom center of the lower pressure plate. A limit mounting assembly is installed on the top of the mounting slide to limit the upper pressure mounting piece.

[0009] Furthermore, the limiting installation assembly includes a mounting plate that fits against the top of the mounting slide, an upper pressure limiting sleeve is fixedly connected to the top of the mounting plate, and a plurality of through-positioning posts are fixedly connected to the top of the mounting slide, with the outer sides of the through-positioning posts corresponding to the inner sides of the mounting plate.

[0010] Furthermore, a flip plate is rotatably connected to the outside of the support column, a traction inclined block is fixedly connected to the upper right side of the flip plate, and multiple lifting rods are fixedly connected to the left side of the flip plate. The inner sides of the lifting rods are rotatably connected to both sides of the bottom end of the push plate.

[0011] Furthermore, the push plate disassembly assembly includes pressing mounting blocks that slide on both sides of the rear end of the mounting slide. The outer side of the pressing mounting block is connected to the rear end of the mounting slide via a second tension spring, and the bottom end of the pressing mounting block is attached to the top end of the bottom support plate.

[0012] Furthermore, the bottom end of the upper push plate is connected to the inner bottom end of the bottom support plate via a first tension spring.

[0013] Furthermore, a fixing bolt is inserted inside the compression mounting block, and a positioning pin is inserted on the right side of the fixing bolt.

[0014] Furthermore, the internal thread of the insertion positioning post is connected to a long bolt, the external end of which passes through the bottom end of the mounting slide and is threaded to the top end of the bottom support plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the top ring of the positioning plate inside the mounting slide is placed on the lower frame to be installed. The mounting slide slides inside the mounting rail. The pressing mounting block on its rear side generates a pushing force on the traction inclined block, thereby flipping the flipping plate and lifting the positioning ejector column upward, so that it is nested inside the bottom groove of the mounting slide and the positioning plate is pushed upward, improving the pressing force effect and improving the convenience of the lower frame positioning installation.

[0017] 2. In this utility model, an installation plate matching the skeleton oil seal is selected. The installation plate is placed on the top of the installation slide. The long rod bolt is inserted into the inside of the insertion positioning column. The long rod bolt is downward and threaded to the top of the bottom support plate, thereby completing the fixation. The upper skeleton to be installed is inserted through the upper pressure limiting sleeve. The skeleton is restricted by the upper pressure limiting sleeve, which makes corresponding contact between the upper skeleton and the lower skeleton, and squeezes between the skeletons, improving the convenience of skeleton connection of the device and ensuring the accuracy of upper skeleton installation.

[0025] 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.

[0026] Reference Figures 1-3This utility model provides an embodiment of a special installation tool for a skeleton oil seal, comprising: a bottom support plate 1 for bottom support; multiple support rods 2 fixedly connected to the top of the bottom support plate 1; an upper support plate 3 fixedly connected to the top of the support rods 2; mounting slide rails 12 fixedly connected to both sides of the top of the bottom support plate 1; mounting slide blocks 11 slidably connected to the outside of the mounting slide rails 12; a positioning plate 10 slidably connected to the inside of the mounting slide blocks 11; an upper push plate 14 slidably connected to the middle of the bottom support plate 1; a positioning ejector post 13 fixedly connected to the top of the upper push plate 14; a support post 18 fixedly connected to the inside of the bottom support plate 1; and a flip-up push assembly installed on the outside of the support post 18 for pushing the skeleton upwards. At the rear end of the mounting slide 11, a push plate disassembly assembly is installed to facilitate complete frame disassembly. A flip plate 17 is rotatably connected to the outside of the support column 18. A traction inclined block 16 is fixedly connected to the upper right side of the flip plate 17, and multiple lifting rods 15 are fixedly connected to the left side of the flip plate 17. The inner sides of the lifting rods 15 are rotatably connected to both sides of the bottom end of the upper push plate 14. The push plate disassembly assembly includes pressing mounting blocks 22 that slide on both sides of the rear end of the mounting slide 11. The outer side of the pressing mounting blocks 22 is connected to the rear end of the mounting slide 11 via a second tension spring 20. The bottom end of the pressing mounting blocks 22 is attached to the top end of the bottom support plate 1. The bottom end of the upper push plate 14 is connected to the inner bottom end of the bottom support plate 1 via a first tension spring 19. (Refer to...) Figure 5 A fixing bolt 21 is inserted inside the compression mounting block 22, and a positioning pin 25 is inserted on the right side of the fixing bolt 21.

[0027] When installing the skeleton oil seal, first place the oil seal inside the ring at the top of the positioning plate 10 in the middle of the mounting slide 11. Carefully inspect and ensure that the surface is free of impurities such as burrs, sand particles, or iron filings. To reduce frictional resistance, apply lithium-based grease evenly at the bearing cap inlet. Then slide the mounting slide 11 along the outside of the mounting slide rail 12 and push it backward. At this time, the pressing mounting block 22 will generate a thrust on the traction inclined block 16. Due to the interaction between the pressing mounting block 22 and the inclined surface of the traction inclined block 16, the flipping plate 17 is pressed downward, causing the lifting connecting rod 15 to flip to the left, thereby pushing... As the upper push plate 14 moves upward, the positioning ejector post 13 rises and embeds into the circular groove at the bottom of the mounting slide 11, lifting the positioning plate 10 upward. This process not only enhances the pressing force effect but also significantly improves the convenience of frame positioning and installation. When disassembly is required, simply pull the positioning pin 25 upward to disengage the fixing bolt 21. At this time, the pressing mounting block 22 unfolds to both sides under the tension of the second tension spring 20. With the contraction of the first tension spring 19, the upper push plate 14 drives the positioning ejector post 13 to retract, making it easy to disassemble and install the slide 11.

[0028] Reference Figure 1 , Figure 3 and Figure 4 A hydraulic cylinder 7 is fixedly connected to the top center of the upper support plate 3. The output end of the hydraulic cylinder 7 is fixedly connected to a lower pressure plate 5. Multiple limit rods 6 are fixedly connected to the top of the lower pressure plate 5. The outer side of the limit rods 6 is slidably connected to the inside of the upper support plate 3. A push column 8 is fixedly connected to the bottom center of the lower pressure plate 5. A limit installation assembly is installed on the top of the mounting slide 11 to limit the upper pressure mounting piece. The limit installation assembly includes a mounting plate 9 that fits against the top of the mounting slide 11. An upper pressure limit sleeve 4 is fixedly connected to the top of the mounting plate 9. Multiple through-positioning pins 23 are fixedly connected to the top of the mounting slide 11. The outer side of the through-positioning pins 23 is respectively inserted into the inside of the mounting plate 9. A long rod bolt 24 is threadedly connected to the inside of the through-positioning pin 23. The outer side of the long rod bolt 24 passes through the bottom of the mounting slide 11 and is threadedly connected to the top of the bottom support plate 1.

[0029] Select a matching mounting plate 9 according to the specifications of the skeleton oil seal, place it on the top of the mounting slide 11, and accurately position it by passing through the mounting plate 9 with the through-positioning pin 23. Then, screw the long bolt 24 into the through-positioning pin 23 so that it extends downward and is threaded to the top of the bottom support plate 1 to complete the fixing of the mounting plate 9. Next, put the upper skeleton to be installed into the upper pressure limiting sleeve 4 to ensure that it is accurately aligned and in contact with the lower skeleton. After starting the hydraulic cylinder 7, the push rod at its output end drives the lower pressure plate 5 to move downward, so that the lower push pin 8 enters the upper pressure limiting sleeve 4 and applies uniform pressure to the upper and lower skeletons. This design not only improves the convenience of skeleton connection, but also ensures the accuracy and stability of the upper skeleton installation.

[0030] Working principle: Place the oil seal skeleton to be installed inside the ring at the top of the positioning plate 10 in the middle of the mounting slide 11, and check to ensure there are no burrs, sand, iron filings, or other debris. Apply lithium-based grease evenly at the bearing cap inlet to reduce frictional resistance during the installation of the oil seal. Then slide the mounting slide 11 into the outside of the mounting slide rail 12 and push the mounting slide 11 backward. This will generate a thrust on the traction inclined block 16 by squeezing the mounting block 22. The squeezing mounting block 22 will contact the inclined surface of the traction inclined block 16, thereby pressing the flipping plate 17 downward. This will flip the left side of the lifting connecting rod 15, thereby pushing the upper push plate 14 upward. At the same time, the positioning ejector post 13 will also be pushed upward, so that the outside of the positioning ejector post 13 is nested inside the bottom circular groove of the mounting slide 11. The positioning ejector post 13 will push the positioning plate 10 upward, increasing the pressure resistance. To enhance the effect of force and improve the ease of installation of the lower frame positioning, a mounting plate 9 matching the frame oil seal is selected. The mounting plate 9 is placed on the top of the mounting slide 11, and the outside of the through positioning post 23 is inserted into the inside of the mounting plate 9, thereby limiting the mounting plate 9. At this time, the long bolt 24 is inserted into the inside of the through positioning post 23 and rotated so that the long bolt 24 is downward and threadedly connected to the top of the bottom support plate 1, thereby completing the fixation. The upper frame to be installed is placed in through the upper pressure limiting sleeve 4. The frame is restricted by the upper pressure limiting sleeve 4 to make corresponding contact between the upper frame and the lower frame. At this time, the hydraulic cylinder 7 is activated, and the push rod at the output end of the hydraulic cylinder 7 presses the lower pressure plate 5 downward. The lower push post 8 enters the inside of the upper pressure limiting sleeve 4, thereby squeezing the frames together, improving the convenience of frame connection and facilitating accurate installation of the upper frame.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
