Description

Technical Field

[0001] This utility model relates to the field of aerospace parts technology, and in particular to a bushing pressing tool. Background Technology

[0002] In the aerospace industry, to improve the strength and wear resistance of locally stressed parts, bushings with various functions are typically pressed into holes in the base material. The most common method for installing bushings is to press them into the lug holes using a hammer, but this method is difficult to control, has poor stability, and is challenging to ensure concentricity. Bushings are prone to deformation during installation, so the lug holes usually need to be machined after installation. If the bushing is under stable stress, the deformation is uniform, and subsequent reaming is easier. However, for complex multi-lug parts, the limited lug space makes bushing installation difficult. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a bushing pressing tool to solve the problems in the background art mentioned above.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: A bushing pressing tool includes a front support rod, a support, a bushing, a locking block, a pressing rod, a rear support rod, and a multi-eared component. The multi-eared component has a base hole and an ear groove for the front and rear support rods to pass through. The front support rod is connected to the support. The pressing rod has, in sequence, a front guide area for guiding the bushing into the base hole, a bushing mounting area for installing the bushing, a locking block mounting area for installing the locking block, and a rear support rod connecting hole for connecting to the rear support rod. The support contacts the front guide area, and the inner diameter of the front guide area is smaller than the inner diameter of the base hole, facilitating the entry of the front guide area into the base hole during bushing pressing.

[0005] In this utility model, the front support rod is provided with an outer circle for guiding and supporting and a support connection hole for connecting the support. The front support rod is connected and fixed to the support with a multi-ear piece.

[0006] In this utility model, the support includes an outer circle and a stepped protrusion for embedding in the front support rod, and the inner diameter of the outer circle is larger than the diameter of the base hole, and the outer circle is short, making it easy to fit into the lug of a multi-lug part.

[0007] In this utility model, the card block has a circular structure, and the inner diameter of the outer circle of the card block is larger than the inner diameter of the pressure rod. The card block is provided with a slot for locking the card block into the card block installation area.

[0008] In this invention, the inner diameter of the card block mounting area is smaller than the inner diameter of the bushing mounting area, which facilitates the movement of the card block.

[0009] In this invention, the rear support rod includes an outer circle and a stepped protrusion for embedding into the rear support rod connection hole. Beneficial effects

[0010] 1) This utility model can install bushings quickly, with good stability, uniform bushing deformation, which facilitates subsequent hole boring and ensures high concentricity when installing multiple lug bushings. 2) This utility model has a simple structure and good versatility. By designing front and rear guide areas of different lengths, it is suitable for installing bushings in ear pieces at different distances. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0019] See Figures 1-7A bushing pressing tool includes a front support rod 1, a support 2, a bushing 3, a locking block 4, a pressing rod 5, a rear support rod 6, and a multi-eared component 7. The multi-eared component 7 has a base hole and an ear slot for the front support rod 1 and the rear support rod 6 to pass through. The front support rod 1 is connected to the support 2. The pressing rod 5 has a front guide area 51, a bushing mounting area 52, a locking block mounting area 53, and a rear support rod connecting hole 54 arranged sequentially. The support 2 contacts the front guide area 51, and the inner diameter of the front guide area 51 is smaller than the inner diameter of the base hole. When pressing the bushing 3, the front guide area 51 enters the base hole. The bushing mounting area 52 is for mounting the bushing 3, the locking block mounting area 53 is for mounting the locking block 4, and the rear support rod connecting hole 54 is for connecting to the rear support rod 6.

[0020] In this embodiment, the front support rod 1 is provided with an outer circle 11 for guiding and supporting and a support connection hole 12 for connecting the support 2. The front support rod 1 and the support 2 are connected and fixed with the multi-ear piece 7.

[0021] In this embodiment, the support 2 includes an outer circle 21 and a stepped protrusion 22 for embedding in the support connection hole 12. The inner diameter of the outer circle 21 is larger than the diameter of the base hole, and the length is short, making it easy to be placed into the lug of the multi-ear part 7.

[0022] In this embodiment, the card block 4 is a circular structure, and the inner diameter of the outer circle 42 of the card block 4 is larger than the inner diameter of the pressure rod 5. A slot 41 for inserting the card block 4 into the card block installation area 53 is provided on the card block 4.

[0023] In this embodiment, the inner diameter of the card block mounting area 53 is smaller than the inner diameter of the bushing mounting area 52, which facilitates the entry and exit of the card block 4.

[0024] In this embodiment, the rear support rod 6 includes an outer circle 61 and a stepped protrusion 62 for embedding into the rear support rod connection hole 54.

[0025] In this embodiment, the steps are as follows: Step 1: Install the bushing 3 on the bushing mounting area 52 of the pressure rod 5, then fix the locking block 4 on the locking block mounting area 53, put the pressure rod 5 into the lug slot of the multi-ear part 7 from direction D, and place the front guide area 51 into the base hole of the multi-ear part 7, then insert the rear support rod 6 into the base hole of the multi-ear part 7 from direction B, and embed the stepped protrusion 62 of the rear support rod 6 into the rear support rod connecting hole 54; Step 2: Place the support 2 into the ear slot of the multi-ear part 7 from direction C, insert the front support rod 1 into the base hole of the multi-ear part 7 from direction A, and insert the stepped protrusion 22 of the support 2 into the support connection hole 12. The tool assembly is now complete. Step 3: Install the press. The press moves from directions A and B towards each other. As the stroke shortens, the clamping block 4 presses the bushing 3 into the base hole of the multi-ear part 7. After installation, pull out the front support rod 1 and the rear support rod 6 in opposite directions, remove the support 2, remove the clamping block 4, and take out the pressure rod 5 along direction B.
