Description

Technical Field

[0001] The present invention relates to the technical field of inertial group testing, and in particular to an assembly and disassembly positioning device for an inertial group and a testing tool. Background Art

[0002] During the use of inertial measurement units (IMUs) and test fixtures, it is crucial to ensure their clamping stability and positioning accuracy. As a key inertial navigation or attitude measurement device, the IMU test process often requires high-precision positioning and stable support to ensure the accuracy of the test data. The test fixture is used to assist in the fixation, adjustment and measurement of the IMU, and requires good compatibility and repeatable positioning capabilities. Under existing technical conditions, there are still many deficiencies in the way the IMU is clamped and positioned, which affects the test efficiency and measurement accuracy.

[0003] Most current clamping methods use rigid fixing structures, such as screws, mechanical fixtures, etc. This type of solution often lacks the ability to adjust the position during the fixing process, resulting in the alignment accuracy of the tooling and the inertial group relying on manual operation. The adjustment process is cumbersome and prone to errors. In addition, for inertial groups of different specifications, traditional fixtures need to be frequently replaced or complexly adapted and modified, and have poor versatility. Once the clamping force is uneven or not adjusted in place, it may also cause the inertial group to produce a small displacement during the test, thereby affecting the stability and consistency of the measurement results.

[0004] Existing locking mechanisms usually use a single mechanical clamping method when clamping tooling, such as manual locking screws or spring compression. This method is difficult to ensure uniform force during the clamping process, especially when the inertia group size is not uniform or the structure is complex. It is easy to cause local over-tightening or over-loosening, resulting in unstable clamping. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an assembly and disassembly positioning device for an inertial group and a test tool, which solves the problem that most current clamping methods use a rigid fixing structure and often lack the ability to adjust the position during the fixing process.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides an assembly and disassembly positioning device for an inertial group and a test tool, comprising: a base 1, a plurality of positioning brackets 2 are fixed on the upper surface of the base 1; a moving component 3, which is arranged on the base 1, and the moving component 3 includes a slide rail 301, the lower surface of the slide rail 301 is fixed to the upper surface of the base 1, an electric slider 302 is slid on the outer wall of the slide rail 301, a placement table 401 is slid on the upper surface of the electric slider 302, a guide rod 303 is fixed on the lower surface of the placement table 401, the outer wall of the guide rod 303 slides inside the electric slider 302, an electric push rod 304 is fixed on the outer wall of the electric slider 302, a support block 305 is fixed on the driving end of the electric push rod 304, and the upper surface of the support block 305 is fixed to the lower surface of the placement table 401; an auxiliary component 4, which is arranged on the electric slider 302, and is used to perform preliminary fixing of the positioned tool Fixed; a locking component 5, which is arranged on the positioning bracket 2, and is used to fix the tooling again; a clamping component 6, which is arranged on the outer wall of the placement table 401, and is used to clamp and position the inertial group; a limiting component 7, which is arranged on the placement table 401, and is used to limit the mounting seat of the tooling, the auxiliary component 4 includes a placement table 401, a top plate 402 is fixed to the top of the placement table 401, a placement plate 403 is penetrated inside the top plate 402, and a plurality of air holes are penetrated inside the placement plate 403, an air pump 404 is fixed to the outer wall of the placement table 401, a connecting pipe 405 is fixed to the input end of the air pump 404, a plurality of exhaust pipes 407 are penetrated on the outer wall of the connecting pipe 405, a mounting block 406 is fixed to the end of the exhaust pipe 407, the lower surface of the mounting block 406 is fixed to the inner bottom of the placement table 401, and a plurality of air nozzles 408 are penetrated on the outer wall of the exhaust pipe 407.

[0031] Specifically, the electric slider 302 slides on the outer wall of the slide rail 301 so that the placement table 401 can accurately control the moving distance during the adjustment process, ensuring that the installation position of the tooling meets the test requirements. The sliding design of the guide rod 303 effectively reduces the shaking that may occur during the movement and improves the overall stability of the device. The driving support block 305 of the electric push rod 304 enables the placement table 401 to provide stable supporting force during the adjustment process to avoid the placement table 401 from shifting during operation. Starting the air pump 404 evenly distributes the airflow to multiple exhaust pipes 407 through the connecting pipe 405, thereby improving the uniformity of adsorption and preventing the tooling from tilting or deforming due to local uneven force during the fixing process.

[0032] Please see attached Figure 4 -Attached Figure 8The locking assembly 5 includes a support plate 501, the outer wall of the support plate 501 is fixed to the outer wall of the positioning bracket 2, a left-right symmetrical cylinder 1 502 is fixed inside the support plate 501, a clamping plate 1 503 is fixed to the driving end of the cylinder 1 502, a support frame 504 is fixed to the upper surface of the clamping plate 1 503, a plurality of cylinders 2 505 are fixed to the top of the support frame 504, a connecting plate 506 is fixed to the driving end of the cylinder 2 505, and a plurality of vacuum suction cups 507 are fixed to the lower surface of the connecting plate 506, a clamping assembly 6 includes a bracket 1 601, an outer wall of the bracket 1 601 is fixed to the outer wall of the placing table 401, a driving screw 602 is connected to the inner thread of the bracket 1 601, one end of the driving screw 602 is rotated with the clamping plate 2 603, the other end of the driving screw 602 is fixed with a connecting block 1 605, and a left-right symmetrical limiting rod 604 is fixed to the outer wall of the clamping plate 2 603, The outer wall of the limiting rod 604 slides on the inner wall of the bracket 1 601, and the outer wall of the connecting block 1 605 is rotated with the connecting block 2 606, and the outer wall of the connecting block 2 606 is fixed with a handle 607, and the inner side of the connecting block 2 606 is fixed with a fixing block 1 608, and the inner side of the connecting block 1 605 is fixed with a fixing block 2 609. By rotating the handle 607, the connecting block 2 606 and the fixing block 1 608 are rotated to impact the fixing block 2 609 to rotate with the connecting block 1 605 and the driving screw 602, and the impact kinetic energy is converted into the kinetic energy of the screw rotation, so as to accurately adjust the position of the clamping plate 2 603. The limiting assembly 7 includes a plurality of limiting blocks 701, and the surface of the limiting block 701 is fitted with the upper surface of the top plate 402. A bolt 702 is passed through the inside of the limiting block 701, and the bottom end of the bolt 702 is threadedly connected to the inside of the top plate 402, and a handle 703 is rotated at the top of the bolt 702.

[0033] Specifically, the cylinder 1 502 can provide a uniform driving force under the left-right symmetrical arrangement, so that the clamping plate 1 503 can achieve synchronous clamping during the clamping process, reduce the problem of uneven force on the tooling, and improve the reliability and stability of clamping. The cylinder 2 505 is started to push the connecting plate 506 to move. The connecting plate 506, through the synergistic effect with the cylinder 2 505, enables the vacuum suction cup 507 to achieve rapid adsorption and release, providing additional fixing force, and at the same time reducing the damage to the tooling surface during the clamping process. The combination of the connecting block 1 605 and the connecting block 2 606 is fine-tuned through manual adjustment, so that the operator can accurately adjust the clamping force, turn the handle 607, and the impact mechanism of the fixed block 1 608 and the fixed block 2 609 converts the rotational kinetic energy into the kinetic energy of the screw rotation, thereby achieving precise control of the clamping plate 2 603, so that the inertial group can be firmly fixed during the clamping process without being damaged due to excessive clamping force.

[0034] Working principle: first, place the tool on the placement table 401, and the slide rail 301 provides a guide for horizontal movement. The electric slider 302 slides on the slide rail 301 to achieve precise adjustment of the tool. The electric push rod 304 further drives the support block 305 to move left and right, so that the placement table 401 can be finely adjusted in the horizontal direction to ensure the initial positioning of the tool. Then, the air pump 404 is started to provide air flow to the exhaust pipe 407 through the connecting pipe 405. The air nozzle 408 on the exhaust pipe 407 generates an adsorption force, so that the placement plate 403 adsorbs and fixes the tool to prevent it from shifting during the adjustment process. After the tool is initially positioned, start the cylinder 1 502 to push the clamping plate 1 503 to clamp the tool to further fix it. Then, the cylinder 2 505 on the support frame 504 drives the connecting plate 506 to move downward, so that the vacuum suction cup 507 installed below it contacts the surface of the tool and generates negative pressure adsorption, thereby achieving re-fixation of the tool. At this time, the limit assembly 7 plays a role, and the limit block 701 The top plate 402 is fitted with the top plate 402 and fixed to the top plate 402 by the internal bolt 702. The top of the bolt 702 is provided with a handle 703, which can be used to manually rotate and adjust the fixing strength of the limit block 701, so as to ensure that the position of the tooling mounting seat will not be offset. After the inertial group is placed on the tooling, the clamping assembly 6 clamps it, and the driving screw 602 is rotated by the threaded connection bracket 1 601, driving the clamping plate 2 603 to tighten inward, applying a stable clamping force to the inertial group, and the limit rod 6 04 slides on the inner wall of bracket 1 601 to limit the lateral movement of clamping plate 2 603 to prevent it from tilting or misalignment. In order to achieve fine control of the clamping force, the operator can rotate connecting block 2 606 through handle 607 to make the fixed block 1 608 inside it hit the fixed block 2 609, and the kinetic energy of the impact drives connecting block 1 605 and driving screw 602 to rotate, thereby accurately adjusting the clamping force so that the inertial group will not be deformed or damaged due to uneven force during the clamping process.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
