The aviation plug positioning clamp comprises a guide rail, and a sliding groove is formed in the top of the guide rail. According to the clamping device, the two first clamping plates and the two second clamping plates can be driven to synchronously move inwards by rotating the hand wheel to perform double centering clamping and positioning on the outer side of the aviation plug, so that the clamping strength is ensured, and the moving distance of the two first clamping plates and the two second clamping plates can be changed by changing the number of turns of rotation of the hand wheel; therefore, aviation plugs with different sizes can be positioned and clamped; the second clamping plate can extrude the spring during clamping, the spring reversely pushes the second clamping plate through the resilience force of the spring, the clamping stability of the second clamping plate to the aviation plug is further improved, and the clamping and positioning stability of the device to the aviation plug can be effectively guaranteed through the self-locking performance of the worm gear and the worm.

Description

Technical Field

[0001] The utility model relates to the technical field of aviation plug fixture tooling, in particular to an aviation plug positioning fixture. Background Art

[0002] During the production of aviation plugs with cables, the pins must be tested to verify their secure installation. Due to their small size and high contact density, aviation plugs can exhibit structural deformation, bending, poor contact, and other issues during testing, especially in challenging operating environments.

[0003] Chinese patent publication number CN219302525U discloses an aviation plug positioning fixture, comprising a base, a support member disposed above the base, and a plug pressure plate located directly above the support member. The support member is provided with a cavity for accommodating the aviation plug, and a boss extending toward the axis at its top. A positioning member for limiting the position of the aviation plug is mortised on the upper surface of the boss, and a circular hole is provided on the plug pressure plate to expose the aviation plug pins. A clamping mechanism is connected between the support member and the plug pressure plate to press the aviation plug onto the positioning member. In this design, the positioning member is disposed on the top boss of the support member to determine the relative position of the aviation plug during assembly, and the three protrusions on the positioning member match the corresponding circular hollow holes on the aviation plug. This vertical fixing method ensures the positioning accuracy of the fixture.

[0004] The above-mentioned existing technical solutions have the following defects: the sizes of the support member and the positioning member are fixed, and the size of the plug pressure plate used to fix the top of the aviation plug is also fixed, which makes it difficult for the device to position and clamp aviation plugs of different sizes, thereby reducing the practicality of the device. In response to the above situation, technical innovation is carried out based on the existing aviation plug positioning fixture. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model can drive the two sets of first clamping plates and the two sets of second clamping plates to move inward synchronously by turning the hand wheel to double-center the outer side of the aviation plug to ensure the clamping strength. By changing the number of turns of the hand wheel, the moving distance of the two sets of first clamping plates and the two sets of second clamping plates can be changed, thereby making it possible to position and clamp aviation plugs of different sizes.

[0021] See also Figure 1-Figure 3 The top of the guide rail 1 is provided with a slide groove, and a driving assembly is placed in the slide groove. A positioning assembly is placed above the guide rail 1, and two sets of fixing sleeves 11 are evenly fixed on the front and rear sides of the guide rail 1. The bolts pass through the fixing sleeves 11 and are screwed with the threaded holes on the external platform, so that the guide rail 1 can be fixed. Two sets of rotating shaft seats 14 are evenly fixed on the right side of the guide rail 1. The positioning assembly includes a storage box 2, and the opposite sides of the two groups of storage boxes 2 are provided with a group of storage grooves. A second clamping plate 22 is slidably provided in the storage groove, and a groove is provided on the top of the second clamping plate 22. A roller 24 is evenly rotated in the groove by a rotating shaft. A group of first clamping plates 21 are fixed on the opposite sides of the two groups of storage boxes 2. The first clamping plate 21 is located above the roller 24, and a group of springs 25 are fixed on the opposite sides of the two groups of second clamping plates 22. The springs 25 are fixed in the storage groove. The front and rear sides of the inner wall of the storage groove are provided with a group of guide grooves, and the front and rear sides of the second clamping plate 22 are fixedly provided with a group of guide blocks 23, which are slidably arranged in the guide grooves, and the second clamping plate 22 is assisted to move stably left and right by the guide blocks 23. The driving assembly includes a two-way screw rod 16, and the two-way screw rod 16 is rotatably arranged in the slide groove of the guide rail 1. The right side of the two-way screw rod 16 passes through the right side of the guide rail 1 and is connected to the worm gear 12. The top of the worm gear 12 is meshed with the worm 13, and the front side of the worm 13 is fixedly provided with a handwheel 15. The outer side wall of the two-way screw rod 16 is evenly screwed with two groups of internal threaded slides 17. The storage box 2 is fixedly provided on the top of the internal threaded slide 17. The two groups of rotating shaft seats 14 are evenly sleeved on the outer side wall of the worm 13, and the worm 13 is supported to rotate by the rotating shaft seat 14. An aviation plug 3 is placed above the guide rail 1, and the aviation plug 3 is located between the two groups of second clamping plates 22 and the two groups of first clamping plates 21.

[0022] Working principle: The bolts are passed through the fixing sleeve 11 and screwed into the threaded holes on the external platform to fix the aviation plug 3. The aviation plug 3 is placed between the two sets of second clamping plates 22 and the two sets of first clamping plates 21, and the hand wheel 15 is turned to drive the worm gear 12 to rotate through the worm 13. The worm gear 12 drives the internal thread slide 17 to move inward synchronously through the two sets of bidirectional screw rods 16, thereby driving the positioning assembly to move synchronously. When the two sets of second clamping plates 22 move to the bottom of the fixing ring of the aviation plug 3, the aviation plug 3 can be placed on the top of the two sets of second clamping plates 22. At this time, continue to turn the hand wheel 15 to make the two sets of second clamping plates 22 continue to move inward to fix the outer surface of the aviation plug 3. The side wall is centered and clamped, and the roller 24 can assist the second clamping plate 22 to slide smoothly on the bottom of the fixed ring of the aviation plug 3. As the handwheel 15 rotates, the two groups of first clamping plates 21 will gradually move inward and perform a second centered clamping and positioning on the outer side of the aviation plug 3. At the same time, the second clamping plate 22 will gradually slide into the storage groove of the storage box 2 due to the obstruction of the aviation plug 3 and squeeze the spring 25. The spring 25 pushes the second clamping plate 22 in the opposite direction through its own rebound force, thereby improving the clamping stability of the second clamping plate 22 on the aviation plug 3, and the self-locking property of the worm gear 12 and the worm 13 can effectively ensure the clamping and positioning stability of the device on the aviation plug 3.
