Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to an adaptive fixture for an aircraft engine oil pump housing. Background Technology

[0002] The fixture for machining the oil pump housing of an aircraft engine is a type of tooling specifically designed to fix and position the oil pump housing workpiece, ensuring that it maintains a precise position during machining.

[0003] Patent CN221110819U discloses a high-efficiency and stable fixture for machining oil pump housings, relating to the field of oil pump housing machining technology. The fixture includes a machining plate body, a clamping plate fixedly installed on the right side of the top of the machining plate body, an auxiliary plate provided on the inner side of the clamping plate, a movable base movably installed on the left side of the top of the machining plate body, a fixture on the top of the movable base, an adjusting shaft movably installed on the outer side of the fixture, and a lifting groove formed on the top of the machining plate body, with a lifting mechanism movably installed inside the lifting groove. This patent achieves the function of clamping and holding by cooperating with the lifting groove, hydraulic column, push plate, telescopic column, and connecting plate, thus improving the practicality of the device.

[0004] As shown in the above technology, when the aero-engine oil pump housing is machined, it needs to be stably clamped by an external clamping device. However, the existing clamps are fixed with screws, which require multiple rotations, resulting in a slow operating speed. Furthermore, they can only clamp the two sides of the aero-engine oil pump housing. In reality, the surface shape of the aero-engine oil pump housing is irregular, and ordinary equipment cannot clamp it tightly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adaptive clamp for the housing of an aero-engine oil pump. This solves the problems of existing clamps that use screws for fixing, require multiple rotations, have slow operation speeds, and can only clamp the two sides of the aero-engine oil pump housing, while the actual surface shape of the aero-engine oil pump housing is irregular, making it impossible for ordinary equipment to clamp it tightly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive clamp for an aircraft engine oil pump housing, comprising:

[0007] A base plate, on one side of the top of which is rotatably connected a telescopic rod, and a connecting plate is fixedly connected to the surface of the telescopic rod;

[0008] A primary clamping assembly, one side of which is fixedly connected to one side of a connecting plate, is used for basic clamping of the aircraft engine oil pump housing.

[0009] A precision clamping assembly, one side of which is fixedly connected to one side of a primary clamping assembly, is used for the precise clamping of an aircraft engine oil pump housing.

[0010] Preferably, the primary clamping assembly includes a stabilizing plate fixedly connected to one side of the connecting plate, a loading plate fixedly connected to the surface of the stabilizing plate, a dovetail rail fixedly connected to one side of the surface of the loading plate, and a dovetail block movably connected to the inner wall of the dovetail rail.

[0011] Preferably, a movable frame is fixedly connected to the surface of the dovetail block, a connector sleeve is fixedly connected to the inner wall of the movable frame, and a screw is threadedly connected to the inside of the connector sleeve.

[0012] Preferably, a positioning sleeve is fixedly connected to one side of the dovetail groove surface, and the number of positioning sleeves is set to multiple.

[0013] Preferably, the precision clamping assembly includes a synchronous bent rod fixedly connected to one side of the primary clamping assembly, and one side of the synchronous bent rod is fixedly connected to a threaded post via a stabilizing pad.

[0014] Preferably, the surface of the threaded column is threadedly connected to an outer expansion sleeve, and a clamping pad is fixedly connected to one side of the outer expansion sleeve.

[0015] This invention provides an adaptive clamp for an aircraft engine oil pump housing. Compared with the prior art, it has the following advantages:

[0016] 1. This self-adaptive clamp for aircraft engine oil pump housing utilizes the primary clamping component to allow the dovetail block to move rapidly on the surface of the dovetail rail. This movement simultaneously moves the clamping pad, facilitating quick and easy adjustment of the clamping pad to the vicinity of the adjustment position. This allows for clamping of large-sized aircraft engine oil pump housings and enables rapid operation during clamping, avoiding the need to spend a significant amount of time rotating the screw rod and thus shortening the operation time.

[0017] 2. This adaptive clamp for the aircraft engine oil pump housing utilizes a precision clamping assembly, multiple outer expansion sleeves, and clamping pads to enable the device to clamp the aircraft engine oil pump housing from multiple points. All of these are precision threaded rotation adjustments, allowing for tight clamping at multiple points. Simultaneously, the clamping pads and outer expansion sleeves can be rotated and detached from the threaded posts. The clamping pads can be replaced to adapt to the aircraft engine oil pump housing, ensuring a complete fit and tight clamping. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides two technical solutions:

[0025] Example 1: An adaptive clamp for an aircraft engine oil pump housing, comprising:

[0026] A base plate 1 is rotatably connected to one side of the top of the base plate 1, and a connecting plate 3 is fixedly connected to the surface of the telescopic rod 2;

[0027] Primary clamping assembly 4, one side of which is fixedly connected to one side of connecting plate 3, is used for basic clamping of the aircraft engine oil pump housing.

[0028] The precision clamping assembly 5 is fixedly connected to one side of the primary clamping assembly 4. The precision clamping assembly 5 is used to precisely clamp the housing of the aircraft engine oil pump. With the setting of the primary clamping assembly 4, the dovetail block 44 can be moved quickly on the surface of the dovetail rail 43. The movement drives the clamping pad 54 to move, which facilitates the quick movement of the clamping pad 54 to the vicinity of the adjustment position. It can clamp the large-sized aircraft engine oil pump housing and achieve rapid operation during the clamping process, avoiding a lot of time to turn the screw rod and shortening the operation time.

[0029] Example 2 differs from Example 1 primarily in that: an adaptive clamp for an aircraft engine oil pump housing, the primary clamping assembly 4 includes a stabilizing plate 41 fixedly connected to one side of a connecting plate 3, a loading plate 42 fixedly connected to the surface of the stabilizing plate 41, a dovetail rail 43 fixedly connected to one side of the loading plate 42, a dovetail block 44 movably connected to the inner wall of the dovetail rail 43, a moving frame 45 fixedly connected to the surface of the dovetail block 44, a connecting sleeve 46 fixedly connected to the inner wall of the moving frame 45, a screw 47 threadedly connected to the internal thread of the connecting sleeve 46, a positioning sleeve 48 fixedly connected to one side of the surface of the dovetail rail 43, the number of positioning sleeves 48 being multiple and evenly distributed on the surface of the dovetail rail 43, the positioning sleeves 48 and the screw 47 being mutually adapted, and the precision clamping assembly 5 including a synchronous bending rod 5 fixedly connected to one side of the primary clamping assembly 4. 1. A threaded post 52 is fixedly connected to one side of the synchronous bending rod 51 via a stabilizing pad. An outer expansion sleeve 53 is threadedly connected to the surface of the threaded post 52. The inner wall of the outer expansion sleeve 53 is threaded. A clamping pad 54 is fixedly connected to one side of the outer expansion sleeve 53. Different clamping pads 54 have different shapes to adapt to the surface shape of the aircraft engine oil pump housing. With the setting of the precision clamping assembly 5 and the setting of multiple outer expansion sleeves 53 and clamping pads 54, the device can clamp the aircraft engine oil pump housing from multiple points. All of them are precision threaded rotation adjustment, which can clamp it tightly at multiple points. At the same time, the clamping pads 54 and the outer expansion sleeves 53 as a whole can be rotated off from the threaded post 52. The clamping pads 54 can be replaced to adapt to the aircraft engine oil pump housing, and can completely fit the aircraft engine oil pump housing, thereby clamping it tightly.

[0030] The telescopic rod 2 is connected to the hydraulic source and equipped with relevant control structures. In actual operation, the top of the base plate 1 is fixedly connected to the external processing device.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, select a suitable clamping pad 54, rotate the outer expansion sleeve 53 and clamping pad 54 into the surface of the threaded column 52, adjust the height of the telescopic rod 2 according to the actual production situation, move the dovetail block 44 on the surface of the dovetail rail 43, and at the same time drive the moving frame 45 and the precision clamping assembly 5 to move as a whole. After quickly moving it to the appropriate position, rotate the screw 47 on the surface of the connecting sleeve 46 and insert the screw 47 into the positioning sleeve 48. The primary clamping assembly 4 is stably fixed. Rotate the outer expansion sleeve 53 on one side of each synchronous bending rod 51, and at the same time drive the clamping pad 54 to move. The clamping pad 54 is in close contact with one side of the surface of the aircraft engine oil pump housing and clamps it tightly. After being fully clamped, the production operation is carried out.
