Description

Technical Field

[0001] This utility model relates to the field of inspection tooling technology, and in particular to an inspection tooling for the tilt amount of a floating seal. Background Technology

[0002] The inspection fixture is used to verify the tilt of the floating seal ring during the assembly process of excavator parts. The fixture consists of a fixed platform, mounting block, slide groove, screw, worm gear, worm, adjusting wheel, moving block, and digital display. When using the inspection fixture to verify the tilt of the floating seal ring during excavator part assembly, the fixed platform is placed on the floating seal ring of the part and aligned. Then, the adjusting wheel is rotated, causing the worm to rotate, which in turn causes the screw to rotate, moving the moving block in the slide groove on the mounting block. This adjusts the contact rod of the digital display to the part. Next, the fixed platform is rotated, allowing it to rotate one full revolution on the assembled floating seal ring, thus rotating the connecting rod one full revolution. The digital display then shows whether the difference between the highest and lowest values ​​of the floating seal ring during the pressing process meets the process requirements.

[0003] The inventors discovered in their daily work that when using the inspection fixture, the fixed platform is simply placed on the floating seal ring. When the worker rotates the fixed platform, the connecting rod of the digital display rotates one revolution. During the worker's rotation of the fixed platform, the fixed platform may shift, which may affect the accuracy of the detected tilt value and cause inspection errors. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, since the fixed platform is simply placed on the floating seal ring, when the worker rotates the fixed platform, the connecting rod of the digital display meter rotates one revolution. During the worker's rotation of the fixed platform, the fixed platform may shift, which may affect the accuracy of the detected tilt value and cause inspection error. Therefore, a floating seal tilt measurement tooling is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a floating seal tilt measurement inspection fixture, comprising a fixed platform, an mounting block fixedly connected to the upper end of the fixed platform, a sliding groove formed on the front of the mounting block, a screw rod provided on the inner wall of the sliding groove, a moving block slidably connected to the inner wall of the sliding groove, the screw rod being threadedly connected to the moving block, a digital display meter inserted at the upper end of the moving block, an assembly assembly provided between the digital display meter and the moving block, an adjusting wheel provided at the left end of the mounting block, a worm gear fixedly connected to the arc surface of the screw rod, a worm gear meshing with one side of the worm gear, the worm gear being fixed to the adjusting wheel, the worm gear being rotatably connected to the mounting block, a fixing assembly provided at the lower end of the fixed platform, the fixing assembly including a rotating ring provided at the lower end of the fixed platform, a plurality of evenly distributed sliding holes formed on the arc surface of the rotating ring, a cross rod slidably connected to the inner wall of the sliding holes, and a pressure block slidably inserted at one end of the cross rod.

[0006] The effect achieved by the above-mentioned components is as follows: by setting the fixing components, when inspecting the floating seal ring, the worker places the fixing platform on the floating seal ring, so that the rotating ring is inserted into the floating seal ring. Then, by pulling the mechanism, the cross bar moves upward in the sliding hole, so that the pressure block is pressed against the bottom of the floating seal ring, thereby fixing the rotating ring to the floating seal ring. Then the worker performs the inspection, thus minimizing the possibility of the fixing platform shifting during rotation and causing errors.

[0007] Preferably, the upper end of the cross bar is rotatably connected to a lead screw, which is threadedly connected to the fixed platform.

[0008] The effect achieved by the above components is that turning the lead screw causes the cross bar to move upward within the sliding hole.

[0009] Preferably, a first spring is fixedly connected to the left end of the pressure block, and the other end of the first spring is fixed to the cross rod.

[0010] The effect achieved by the above-mentioned components is to reset the pressure block by setting the first spring.

[0011] Preferably, a pull rope is fixedly connected to the left end of the pressure block, and the pull rope passes through the cross rod and the lead screw.

[0012] The effect achieved by the above components is that pulling the pull rope causes the pressure block to retract completely into the cross bar, thus preventing the rotating ring from getting stuck in the floating seal ring.

[0013] Preferably, a bearing is provided between the rotating ring and the fixed platform, wherein the inner ring of the bearing is fixed to the rotating ring, and the outer ring of the bearing is fixed to the fixed platform.

[0014] The effect achieved by the above components is to improve the rotational stability of the fixed platform on the rotating ring by setting bearings.

[0015] Preferably, the assembly includes a fixing ring fixedly connected to the arc surface of the digital display, the fixing ring being inserted into a movable block, and a pin being slidably inserted into the inner wall of the movable block, the pin being inserted into the fixing ring.

[0016] The effect achieved by the above components is as follows: when the worker installs the digital display, he drags the digital display so that the fixing ring is inserted into the moving block, and then the pin is inserted into the fixing ring, thereby installing the digital display.

[0017] Preferably, a second spring is fixedly connected to the right end of the pin, and the other end of the second spring is fixed to the moving block.

[0018] The effect achieved by the above-mentioned components is to reset the pin by setting a second spring.

[0019] Preferably, an operating rope is fixedly connected to the right end of the pin, and the operating rope passes through the moving block.

[0020] The effect achieved by the above components is to pull the operating rope, causing the pin to move.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting a fixing component, during the inspection of the floating seal ring, the worker places the fixing platform on the floating seal ring, causing the rotating ring to engage within it. Then, through a pulling mechanism, the cross bar moves upward within the sliding hole, causing the pressure block to press against the bottom of the floating seal ring, thereby fixing the rotating ring to the floating seal ring. The worker then performs the inspection. This method minimizes the risk of the fixing platform shifting during rotation, thus preventing errors. It solves the problem that when the fixing platform is simply placed on the floating seal ring, the worker rotates the platform, causing the connecting rod of the digital display meter to rotate one revolution. During this rotation, the fixing platform may shift, potentially affecting the accuracy of the detected tilt value and causing inspection errors. Attached Figure Description

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a floating seal tilt measurement inspection fixture includes a fixed platform 1, an installation block 4 fixedly connected to the upper end of the fixed platform 1, a sliding groove 5 opened on the front of the installation block 4, a screw 6 provided on the inner wall of the sliding groove 5, a moving block 7 slidably connected to the inner wall of the sliding groove 5, the screw 6 and the moving block 7 being threadedly connected, a digital display 8 inserted at the upper end of the moving block 7, an assembly component 3 provided between the digital display 8 and the moving block 7, an adjusting wheel 9 provided at the left end of the installation block 4, a worm gear 11 fixedly connected to the arc surface of the screw 6, a worm 10 meshing with one side of the worm gear 11, the worm 10 being fixed to the adjusting wheel 9, the worm 10 being rotatably connected to the installation block 4, and a fixing component 2 provided at the lower end of the fixed platform 1.

[0029] The following section will explain the specific settings and functions of the fixed component 2 and the assembly component 3.

[0030] Reference Figure 4As shown in this embodiment: the fixing component 2 includes a rotating ring 21 disposed at the lower end of the fixing platform 1. The rotating ring 21 has multiple evenly distributed sliding holes 22 on its arc surface. A cross rod 23 is slidably connected to the inner wall of each sliding hole 22. A pressure block 24 is slidably inserted into one end of the cross rod 23. By setting the fixing component 2, during the inspection of the floating seal ring, the worker places the fixing platform 1 on the floating seal ring, causing the rotating ring 21 to engage within the floating seal ring. Then, through a pulling mechanism, the cross rod 23 moves upward within the sliding hole 22, causing the pressure block 24 to press against the bottom of the floating seal ring, thereby fixing the rotating ring 21 to the floating seal ring. The worker then performs the inspection, thus minimizing the risk of the fixing platform 1 shifting during rotation and causing errors. A lead screw is rotatably connected to the upper end of the cross rod 23. 26. The lead screw 26 is threadedly connected to the fixed platform 1. Tightening the lead screw 26 causes the cross rod 23 to move upward in the sliding hole 22. The left end of the pressure block 24 is fixedly connected to the first spring 25. The other end of the first spring 25 is fixed to the cross rod 23. By setting the first spring 25, the pressure block 24 is reset. The left end of the pressure block 24 is fixedly connected to the pull rope 27. The pull rope 27 passes through the cross rod 23 and the lead screw 26. Pulling the pull rope 27 causes the pressure block 24 to be completely retracted into the cross rod 23, so as to avoid affecting the rotating ring 21 from being stuck in the floating seal ring. A bearing 28 is set between the rotating ring 21 and the fixed platform 1. The inner ring of the bearing 28 is fixed to the rotating ring 21, and the outer ring of the bearing 28 is fixed to the fixed platform 1. By setting the bearing 28, the rotational stability of the fixed platform 1 on the rotating ring 21 is improved.

[0031] Reference Figure 3 As shown in this embodiment: Assembly component 3 includes a fixing ring 31 fixedly connected to the arc surface of digital display 8. The fixing ring 31 is inserted into the moving block 7. A pin 32 is slidably inserted into the inner wall of the moving block 7. The pin 32 is inserted into the fixing ring 31. When the worker installs the digital display 8, he drags the digital display 8 so that the fixing ring 31 is inserted into the moving block 7. Then the pin 32 is inserted into the fixing ring 31, thereby installing the digital display 8. A second spring 33 is fixedly connected to the right end of the pin 32. The other end of the second spring 33 is fixed to the moving block 7. By setting the second spring 33, the pin 32 is reset. An operating rope 34 is fixedly connected to the right end of the pin 32. The operating rope 34 passes through the moving block 7. Pulling the operating rope 34 causes the pin 32 to move.

[0032] Working principle:

[0033] When using inspection fixtures to verify the tilt of the floating seal ring during the assembly of excavator parts, the fixed platform 1 is placed on the floating seal ring of the part for alignment. Then, the adjusting wheel 9 is rotated, causing the worm gear 10 to rotate, which in turn causes the worm wheel 11 to rotate, which in turn causes the screw 6 to rotate. This causes the moving block 7 in the slide groove 5 on the mounting block 4 to move, thereby adjusting the digital display 8 (the digital display 8 can be a Mitutoyo model). The 543-300B) special connecting rod contacts the component, then the fixed platform 1 is rotated, causing the fixed platform 1 to rotate one revolution on the assembled floating seal ring, thus rotating the connecting rod one revolution. The difference between the highest and lowest point values ​​of the floating seal ring during the pressing process can be seen through the digital display 8. When inspecting the floating seal ring, the worker places the fixed platform 1 on the floating seal ring, so that the rotating ring 21 is inserted into the floating seal ring. Then, the screw 26 is turned, so that the cross bar 23 moves upward in the sliding hole 22, causing the pressure block 24 to press against the bottom of the floating seal ring, thereby fixing the rotating ring 21 to the floating seal ring. Then the worker performs inspection again to achieve the desired result. To prevent the fixed platform 1 from shifting during rotation and causing errors, a first spring 25 is used to reset the pressure block 24. Pulling the pull rope 27 allows the pressure block 24 to fully retract into the cross bar 23, preventing it from affecting the rotating ring 21 from being stuck into the floating seal ring. By setting the bearing 28, the rotational stability of the fixed platform 1 on the rotating ring 21 is improved. When the worker installs the digital display 8, the worker drags the digital display 8 so that the fixed ring 31 is inserted into the moving block 7. Then, the pin 32 is inserted into the fixed ring 31 to install the digital display 8. A second spring 33 is used to reset the pin 32. Pulling the operating rope 34 moves the pin 32.
