Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a tooling and fixture for an oil mixing and sealing pair test device. Background Technology

[0002] The oil distribution sealing assembly includes an oil distribution ring and an oil distribution short post, with the short post coaxially inserted into the inner hole of the oil distribution ring. The short post has two axially extending oil holes, which are respectively connected to the forward and reverse oil chambers of the pitch control propeller's hydraulic cylinder. The oil distribution ring has two annular oil chambers, which are connected to the two oil holes via radial holes on the short post. The annular oil chambers are connected to the hydraulic system via oil inlets. During the oil distribution sealing assembly test, the assembly needs to be clamped at both ends. Current clamping methods primarily involve modifying various conventional vehicles (modified) as drive devices, equipped with frequency converters and frequency converter control cabinets, capable of driving the oil distribution shaft to rotate and adjust its speed. One end of the oil distribution sealing assembly is fixed to a three-jaw chuck, and the other end is held in place by a center. The point of contact between the center and the end of the oil distribution sealing assembly is relatively small, making it prone to localized damage during high-speed rotation and exhibiting poor stability. Utility Model Content

[0003] The purpose of this invention is to provide a tooling fixture for an oil mixing and sealing pair test device to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a tooling fixture for an oil-sealing pair test device, including a lathe body, a main unit box fixed to one side of the top of the lathe body, a three-jaw chuck installed on the main unit box, a side frame fixed to the top of the lathe body away from the main unit box, a telescopic positioning member coaxial with the three-jaw chuck slidably inserted into the side frame, a sleeve connected to the end of the telescopic positioning member near the three-jaw chuck through a peripheral connection, a storage cylinder fixed to the end of the sleeve away from the side frame, a plurality of ring-shaped clamping members fixed on the inner side wall of the storage cylinder, a clamping member extending into the sleeve slidably inserted at the center of the inner side wall of the storage cylinder, and the clamping members can elastically expand outward along the center of the clamping member.

[0005] The aforementioned components achieve the following effects: the three-jaw chuck can clamp and position the end of the oil-distributing sealing assembly, while the main unit can drive the three-jaw chuck and the oil-distributing sealing assembly during testing. In addition, by pushing the telescopic positioning component until the other end of the oil-distributing sealing assembly extends into the storage cylinder and is locked in place, the ring-shaped clamping components elastically expand outward along the center of the clamping component, performing multi-point clamping and holding of the end of the oil-distributing sealing assembly. Furthermore, the clamping component can further improve the clamping stability of the oil-distributing sealing assembly by clamping the end of the oil-distributing sealing assembly.

[0006] Preferably, the clamping member includes a slide rail fixed to the inner wall of the storage tube, a sliding sleeve slidably sleeved on the slide rail, a clamping block fixed to the outside of the sliding sleeve, a clamping inclined surface on the clamping block, and a clamping spring fixed on the clamping block that abuts against the inner wall of the storage tube.

[0007] The effect achieved by the above components is as follows: the clamping inclined surface on the clamping block abuts and presses against the end of the oil distribution sealing assembly, and the sliding sleeve makes the clamping block move along the slide rail and press the clamping spring. The clamping spring's pressing action realizes multi-point clamping of the end of the oil distribution sealing assembly, and also facilitates clamping and limiting of oil distribution sealing assemblies of different diameters.

[0008] Preferably, the clamping member includes a clamping post with a slot. The clamping post is slidably inserted into the center of the side wall of the storage tube through the slot. One end of the clamping post extends into the sleeve, and a clamping spring is fixed to the inner end of the slot to abut against the inner wall of the storage tube.

[0009] The effect achieved by the above components is that the clamping column, in conjunction with the clamping spring, can clamp the end of the oil distribution sealing assembly.

[0010] Preferably, the telescopic positioning component includes a guide rod rotatably connected to the sleeve, the guide rod having a clamping groove, the guide rod being slidably inserted into the side frame, and a clamping bolt being threaded into the top of the side frame and abutting against the inner wall of the clamping groove.

[0011] The effect achieved by the above components is as follows: by pushing the guide rod to make the clamping and holding parts abut against the end of the oil distribution sealing assembly, and then tightening the clamping bolts, the purpose of clamping the two ends of the oil distribution sealing assembly is achieved.

[0012] Preferably, the lathe body is provided with a collection groove for collecting leaked oil.

[0013] The effect achieved by the above components is that the collection tank can collect the oil leakage from the oil sealing assembly during the experiment.

[0014] This utility model provides an improved tooling fixture for an oil mixing and sealing pair test device, which has the following improvements and advantages compared with the prior art:

[0015] This invention utilizes the clamping inclined surface on the clamping block to abut and press against the end of the oil distribution sealing assembly. In conjunction with the sliding sleeve, the clamping block moves along the slide rail and presses against the clamping spring. The clamping spring's pressing action enables multi-point clamping of the end of the oil distribution sealing assembly. It also facilitates clamping and limiting of oil distribution sealing assemblies of different diameters. Attached Figure Description

[0023] This utility model provides an improved tooling fixture for an oil mixing and sealing pair testing device. The technical solution of this utility model is as follows:

[0024] In embodiments of this utility model, such as Figures 1-3As shown, a tooling fixture for an oil sealing pair test device includes a lathe body 1. The lathe body 1 has a collection groove for collecting leaked oil. A main unit housing 2 is fixed to one side of the top of the lathe body 1. A three-jaw chuck 3 is mounted on the main unit housing 2. A side frame 4 is fixed to the top of the lathe body 1 away from the main unit housing 2. A telescopic positioning component 5, coaxial with the three-jaw chuck 3, is slidably inserted into the side frame 4. The telescopic positioning component 5 includes a guide rod 51 rotatably connected to a sleeve 6. A clamping groove 52 is provided on the guide rod 51. The guide rod 51 is slidably inserted into the side frame. On the side frame 4, a clamping bolt 53 is threaded into the top of the side frame 4 and abuts against the inner wall of the clamping groove 52. After the guide rod 51 is pushed to make the clamping part 8 and the clamping part 9 abut against the end of the oil distribution sealing assembly, the clamping bolt 53 is tightened to achieve the purpose of clamping both ends of the oil distribution sealing assembly. The end of the telescopic positioning part 5 near the three-jaw chuck 3 is connected to the sleeve 6 through the periphery. The end of the sleeve 6 away from the side frame 4 is fixed to the storage cylinder 7. Multiple ring-shaped clamping parts 9 are fixed on the inner wall of the storage cylinder 7. The clamping parts 9 include those fixed to the inner wall of the storage cylinder 7. The slide rail 91 has a sliding sleeve 92 mounted on it. A clamping block 93 is fixed to the outside of the sliding sleeve 92. The clamping block 93 has a clamping inclined surface 94. A clamping spring 95 is fixed on the clamping block 93 and abuts against the inner wall of the storage cylinder 7. The clamping inclined surface 94 on the clamping block 93 abuts against and presses against the end of the oil distribution sealing assembly. In conjunction with the sliding sleeve 92, the clamping block 93 moves along the slide rail 91 and presses against the clamping spring 95. The clamping action of the clamping spring 95 achieves multi-point clamping of the end of the oil distribution sealing assembly. To facilitate the clamping and limiting of oil distribution sealing assemblies of different diameters, a clamping member 8 extending into the sleeve 6 is slidably inserted at the center of the inner side wall of the storage cylinder 7. The clamping member 8 includes a clamping post 81 with a slot 82. The clamping post 81 is slidably inserted into the center of the side wall of the storage cylinder 7 through the slot 82.

In addition, by pushing the telescopic positioning member 5 until the other end of the oil distribution sealing assembly extends into the storage cylinder 7 and is locked, the clamping inclined surface 94 on the clamping block 93 abuts and presses against the end of the oil distribution sealing assembly. With the cooperation of the sliding sleeve 92, the clamping block 93 moves along the slide rail 91 and presses against the clamping spring 95. The clamping action of the clamping spring 95 realizes the multi-point clamping work of the end of the oil distribution sealing assembly. In addition, the clamping column 81 can cooperate with the clamping spring 83 to clamp the end of the oil distribution sealing assembly.
