Description

Technical Field

[0001] This utility model relates to the technical field of oil seal leakage detection devices, specifically a pressure fitting tool for oil seal leakage detection. Background Technology

[0002] The oil seal leakage detection press fitting is a specialized device that integrates press fitting and detection functions. It is used to ensure that the press fitting force is appropriate and the position is accurate during the oil seal installation process, and to test its sealing performance after press fitting to prevent oil leakage. It uses a pneumatic or mechanical mechanism (such as a cylinder-driven press fitting component) to press the oil seal into the component (such as a housing or metal sleeve), while using sensors to monitor the press fitting force and pull-out force, avoiding sealing failure caused by improper interference fit, assembly tilt or deformation, thereby efficiently monitoring and verifying the oil seal assembly quality on the production site.

[0003] However, in the existing press-fitting fixtures, the positioning of the metal sleeve is usually achieved by simply opening a positioning hole on the base and inserting the positioning rod of the metal sleeve into the positioning hole. This positioning method has too many limitations and can only effectively position parts of various specifications. Utility Model Content

[0004] The purpose of this invention is to provide a press-fitting tool for detecting oil seal leakage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a press-fitting fixture for detecting oil seal leakage, comprising: a base, a bracket fixed to the top of the base, a hydraulic device fixed on the bracket, a hydraulic rod of the hydraulic device movably inserted into the bracket, a press-in block fixed on the hydraulic rod of the hydraulic device, a slide rail provided on the base, a first slider and a second slider slidably connected in the slide rail, a first clamping plate fixed to the top of the first slider, a second clamping plate fixed to the top of the second slider, a first lead screw hole and a second lead screw hole provided on the base, a first lead screw and a second lead screw rotatably connected in the first lead screw hole and the second lead screw hole respectively, and the first lead screw movably mounted on the first slider.

[0006] Preferably, the slide rail has a rectangular groove structure, the first slider and the second slider both have a rectangular block structure, a lead screw mounting sleeve is fixed on the first slider, and a rotating plate is fixed to one end of the first lead screw, which is rotatably connected in the lead screw mounting sleeve.

[0007] Preferably, a spring is fitted on the second lead screw, with one end of the spring abutting against the inner wall of the slide rail and the other end of the spring abutting against the second slider.

[0008] Preferably, both the first clamping plate and the second clamping plate are semi-circular annular plate structures, and a pull rod is fixed to the end of the second clamping plate away from the first clamping plate. The pull rod has an "L" shaped rod structure.

[0009] Preferably, a central hole is provided at the very center of the base, and the central hole has a circular hole structure.

[0010] Preferably, a metal sleeve is movably connected between the first clamping plate and the second clamping plate, and an oil seal is movably inserted into the metal sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The oil seal leakage detection press fitting proposed in this utility model involves rotating the first lead screw to move the first slider towards the center hole until the distance between the inner ring of the first clamping plate and the center line of the center hole is equal to the diameter of the metal sleeve. Then, the second clamping plate is moved away from the first clamping plate. The metal sleeve is then placed between the first and second clamping plates, and the second clamping plate is released. Finally, the second lead screw is rotated to move towards the center hole. The second lead screw pushes the second slider, causing the second slider to move the second clamping plate so that the second clamping plate abuts against the other end of the metal sleeve, thereby clamping the metal sleeve in the middle position of the base and achieving the positioning of the metal sleeve.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1: Please refer to Figures 1 to 3This utility model provides a technical solution: a press-fit fixture for detecting oil seal leakage, comprising: a base 1, a bracket 2 fixed to the top of the base 1, a hydraulic device 3 fixed to the bracket 2, a hydraulic rod of the hydraulic device 3 movably inserted into the bracket 2, a press-in block 4 fixed to the hydraulic rod of the hydraulic device 3, a slide rail 7 provided on the base 1, a first slider 8 and a second slider 9 slidably connected in the slide rail 7, a first clamping plate 10 fixed to the top of the first slider 8, a second clamping plate 11 fixed to the top of the second slider 9, a first lead screw hole 12 and a second lead screw hole 15 provided on the base 1, a first lead screw 13 and a second lead screw 16 rotatably connected in the first lead screw hole 12 and the second lead screw hole 15 respectively, the first lead screw 13 being movably mounted on the first slider 8; a central hole 20 provided at the center of the base 1, the central hole 20 being a circular hole structure; a metal sleeve 6 movably connected between the first clamping plate 10 and the second clamping plate 11, an oil seal 5 being movably inserted into the metal sleeve 6.

[0016] When pressing the oil seal 5 into the metal sleeve 6, first rotate the first lead screw 13 and the second lead screw 16. Under the action of the threaded connection between the first lead screw hole 12 and the first lead screw 13, as well as the second lead screw hole 15 and the second lead screw 16, the first lead screw 13 and the second lead screw 16 move away from each other. Then, according to the diameter of the metal sleeve 6 to be pressed into the oil seal, rotate the first lead screw 13 to make the first slider 8 drive the first clamping plate 10 to move towards the central hole 20 until the distance between the inner ring of the first clamping plate 10 and the center line of the central hole 20 is close to that of the metal sleeve. The diameters of the metal sleeves 6 are equal. Then, the second clamping plate 11 is moved away from the first clamping plate 10. The metal sleeve 6 is then placed between the first clamping plate 10 and the second clamping plate 11. The second clamping plate 11 is then released. Finally, the second lead screw 16 is rotated to move closer to the central hole 20. The second lead screw 16 pushes the second slider 9, causing the second slider 9 to drive the second clamping plate 11 so that the second clamping plate 11 abuts against the other end of the metal sleeve 6, thereby clamping the metal sleeve 6 in the middle position of the base 1 and achieving the positioning of the metal sleeve 6.

[0017] Example 2: Based on Example 1, in order to realize the rotational connection between the first slider 8 and the first lead screw 13, the slide rail 7 is a rectangular groove structure, the first slider 8 and the second slider 9 are both rectangular block structures, the lead screw mounting sleeve 18 is fixed on the first slider 8, and a rotating plate 19 is fixed at one end of the first lead screw 13. The rotating plate 19 is rotatably connected in the lead screw mounting sleeve 18.

[0018] During the production of this equipment, the lead screw mounting sleeve 18 is fitted onto the first lead screw 13, then the rotating plate 19 is welded to the first lead screw 13, and finally the lead screw mounting sleeve 18 is welded to the first slider 8, thereby realizing the rotational connection between the first slider 8 and the first lead screw 13.

[0019] Example 3: Based on Example 2, in order to achieve the pre-positioning of the metal sleeve 6, a spring 17 is sleeved on the second lead screw 16. One end of the spring 17 abuts against the inner wall of the slide rail 7, and the other end of the spring 17 abuts against the second slider 9. The first clamping plate 10 and the second clamping plate 11 are both semi-circular arc-shaped annular plate structures. A pull rod 14 is fixed to the end of the second clamping plate 11 away from the first clamping plate 10. The pull rod 14 has an "L" shaped rod structure.

[0020] When the second clamping plate 11 is moved, it is easier to move the lever 14. When the second clamping plate 11 is moved away from the first clamping plate 10, the second slider 9 also moves away from the first slider 8. This compresses the spring 17. After the metal sleeve 6 is placed between the first clamping plate 10 and the second clamping plate 11, the lever 14 is released. The spring 17 then pushes the second slider 9 towards the first slider 8, so that the second clamping plate 11 abuts against the end of the metal sleeve 6 away from the first clamping plate 10. The elasticity of the spring 17 provides a preload force to the metal sleeve 6, achieving the pre-positioning of the metal sleeve 6 and preventing the metal sleeve 6 from shifting when the second lead screw 16 is rotated.

[0021] In actual use, when the oil seal 5 needs to be pressed into the metal sleeve 6, first rotate the first lead screw 13 and the second lead screw 16. Under the action of the threaded connection between the first lead screw hole 12 and the first lead screw 13, as well as the second lead screw hole 15 and the second lead screw 16, the first lead screw 13 and the second lead screw 16 will move away from each other. Then, according to the diameter of the metal sleeve 6 to be pressed into the oil seal, rotate the first lead screw 13 to make the first slider 8 drive the first clamping plate 10 to move closer to the central hole 20 until the distance between the inner ring of the first clamping plate 10 and the center line of the central hole 20 is equal to the diameter of the metal sleeve 6. Then, move the second clamping plate 11 away from the center. The metal sleeve 6 is moved away from the first clamping plate 10 and then placed between the first clamping plate 10 and the second clamping plate 11. Then the second clamping plate 11 is released, and finally the second lead screw 16 is rotated to move towards the middle hole 20. The second lead screw 16 pushes the second slider 9, causing the second slider 9 to drive the second clamping plate 11 to press against the other end of the metal sleeve 6, thereby clamping the metal sleeve 6 in the middle position of the base 1 and realizing the positioning of the metal sleeve 6. After positioning, the oil seal 5 is loosely pressed into the inner ring of the metal sleeve 6, and then the hydraulic device 3 pushes the pressing block 4 downward to press the oil seal 5 into the metal sleeve 6.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
