Description

Technical Field

[0001] This utility model relates to the field of level detection instruments, specifically a level detection instrument for a precision inertial navigation counterweight. Background Technology

[0002] Inertial navigation is a method of guidance that utilizes the inertial properties of an object. Its core lies in using a guidance device installed inside the aircraft, combined with gyroscopes and accelerometers, to measure the angular rate and acceleration information of the carrier. The velocity and position information of the carrier are obtained through integration calculations. In a precision inertial navigation system, a counterweight is required to balance the weight. When manufacturing the inertial navigation counterweight, a leveling instrument is needed to check the level of the counterweight to ensure that the counterweight is balanced.

[0003] The existing patent with authorization announcement number "CN214560209U" discloses a horizontal inspection tooling fixture, including a base, a horizontal adjustment device disposed on the base, a pointer meter disposed on the base, a fixed plate disposed on the base, a workpiece placement stage disposed on the fixed plate, a clamping mechanism disposed on the workpiece placement stage, a lifting rod disposed on the fixed plate, a slide rail disposed on the lifting rod, a limiting block disposed on the slide rail, a slider disposed on the slide rail, and a horizontal inspection device disposed on the slider. It effectively solves the problem of workpiece instability and error in inspection results during the inspection process, and improves the quality of workpieces.

[0004] However, this device has the following shortcomings:

[0005] 1. After detecting defective products, they are often repaired. However, when the above-mentioned device detects defective products, it is difficult to draw the floating curve of the detection surface based on the floating of the product detection surface. This makes it difficult to judge the uneven parts of the product when it is repaired again.

[0006] 2. When the above-mentioned device is testing the counterweight, it is difficult to automatically alarm the staff when a defective product is detected, which makes it impossible for the staff to quickly judge the product defect. Utility Model Content

[0028] Please see Figure 1-5 The present invention provides an embodiment of a leveling instrument for a precision inertial navigation counterweight, comprising a base 1, mounting brackets 4 on both sides of the top of the base 1, a groove 5 at one end of the mounting bracket 4, a sliding groove 12 at one end of the inner side of the groove 5, a slider 11 slidably connected to the inner side of the sliding groove 12, a sleeve block 8 at one end of the slider 11, a guide rod 13 sleeved on the inner side of the sleeve block 8, an adjusting bolt 10 threadedly connected to the bottom of the guide rod 13, a roller 6 sleeved on the bottom of the adjusting bolt 10, and a movable block 7 at the top of the guide rod 13.

[0029] Both the movable block 7 and the sleeve block 8 are provided with a connecting rod 14 at one end. The two sets of connecting rods 14 are respectively provided with a sliding plate A15 and a sliding plate B16 at one end.

The top of the mounting frame 4 is equipped with a fixing groove 9, and one end of the fixing groove 9 is equipped with two sets of indicator lights 18. One set of indicator lights 18 is a red indicator light, and the other set of indicator lights 18 is a yellow indicator light, which makes it easy to distinguish the unevenness of the counterweight. The top and bottom of the inner side of the fixing groove 9 are equipped with conductive strips 23. The end of the moving block 7 away from the connecting rod 14 is equipped with a fixing rod 22. The outer side of the fixing rod 22 is slidably fitted with a moving block 21. The top and bottom of the moving block 21 are equipped with electric contacts 19 that cooperate with the conductive strips 23. The outer side of the guide rod 13 is fitted with a spring 20 that is connected to the sleeve block 8. When a defective product is detected, the indicator light 18 can be activated to remind the staff.

[0031] The mounting frame 4 is equipped with clamping components on both sides. The clamping components include clamping plates 2 and electric push rods 3. Electric push rods 3 are provided at the bottom of both sides of the mounting frame 4. The output ends of the two sets of electric push rods 3 are equipped with clamping plates 2, which are used to clamp and fix the test products and improve the test stability.

[0032] Furthermore, guide grooves are provided on both sides of the top of the base 1 near the mounting bracket 4, and guide blocks that cooperate with the guide grooves are provided at the bottom of the two sets of clamping plates 2, which can guide the clamping plates 2 and improve the stability of the movement.

[0033] Furthermore, a movable groove is provided on the inner side of the sliding plate A15, and the sliding plate B16 is fitted inside the movable groove. A pull ball is provided on the top of one end of the sliding plate B16, so that the sliding plate A15 can slide along the outer side of the sliding plate B16. The pull ball facilitates the pulling of the roller 6 to inspect the product.

[0034] Furthermore, the marking assembly 17 includes a marker, a socket, a bolt, and a nut. A socket is provided at the bottom of one end of the sliding plate A15 and the sliding plate B16, and a marker is fitted inside the socket. A nut is provided at the bottom of the sliding plate A15 and the sliding plate B16, and a bolt that mates with the marker is threaded on the inner side of the nut. The shape of the product inspection surface can be drawn, and the marker can be easily replaced. After loosening the bolt, the marker can be removed from the socket for replacement. After replacement, the bolt can be rotated to fix the marker.

[0035] Furthermore, limit blocks are provided at the bottom of both ends of the sleeve block 8, and limit rods connected to roller 6 are sleeved on the inner side of the two sets of limit blocks. An adjustment groove is provided at one end of the sleeve block 8, and the adjustment bolt 10 is located inside the adjustment groove, which can guide the roller 6 and facilitate the adjustment of the height of the roller 6 by rotating the adjustment bolt 10.

[0036] Working principle: When performing horizontal testing on the precision inertial navigation counterweight, the device can place the counterweight inside the mounting frame 4, so that one end of the counterweight is in contact with the two sets of marking components 17. Then, the electric push rod 3 is activated to drive the two sets of clamping plates 2 to clamp the counterweight, and the testing can be started.

[0037] Before testing, the roller 6 needs to be slid to the far left. Then, the sliding plate B16 is moved from left to right by the pull ball. The sliding plate B16 can drive the roller 6 to roll along the detection surface of the counterweight. When the product is qualified, the indicator light 18 will not be activated. When the detection surface of the product is unqualified, the guide rod 13 can be pushed up or down according to the unevenness of the inspection. At this time, the guide rod 13 can drive the movable block 7 to move the moving block 21. When the moving block 21 drives the top set of electrical contacts 19 to contact the top conductive strip 23, the red indicator light 18 can be activated to indicate that the top of the counterweight is protruding. Conversely, when the moving block 21 moves down and drives the bottom electrical contacts 19 to contact the bottom conductive strip 23, the yellow indicator light 18 is activated, causing the top of the counterweight to be concave, which makes it easier for the staff to grasp the defect of the counterweight.

[0038] When the sliding plate B16 slides, a horizontal line can be drawn on the end face of the counterweight by a set of marking components 17. The sliding plate A15, which follows the rise and fall of the roller 6, will drive another set of marking components 17 to make a floating curve on the detection surface of the counterweight. When the product level test is not qualified, the staff can adjust the counterweight by observing the comparison between the curve and the horizontal line.
