Description

Technical Field

[0002] An inertial gyro drift test device is a device specifically used to measure and evaluate the drift phenomenon of a gyro in inertial space. Gyro drift refers to the phenomenon that the angle measured by the gyro shifts over time due to various errors and imperfections.

[0039] The swinging member 201 is used to drive the gyroscope 104 to swing, so that the gyroscope 104 can be tested in multiple dimensions. The clamping member 202 is used to clamp and fix the gyroscope 104. The triggering member 203 is used to connect the reset member 204, so that the reset member 204 can drive the clamping member 202 to move, thereby releasing the clamping member 202 from clamping the gyroscope 104.

[0040] Specifically, the first rotating member 102 includes a rotating disk 102a, a rotating column 102b, a driving motor 102c, a driving gear 102d and a rotating frame 102e.

[0043] The support disk 103a is used to support the rotating plate 103b. By starting the rotating motor 103c, the support disk 103a can be driven to rotate, so that the support disk 103a drives the rotating plate 103b to rotate, and the rotating plate 103b drives the gyroscope 104 to rotate in the vertical direction.

[0044] Specifically, the swinging member 201 includes a fixed plate 201a, a fixing bolt 201b, a support shaft 201c and a driving seat 201d. The fixed plate 201a is located on one side of the rotating frame 102e. The fixing bolt 201b is connected to the rotating frame 102e by threaded rotation. The fixed plate 201a is fixed by the fixing bolt 201b, the support shaft 201c is fixed on one side of the fixed plate 201a, and the driving seat 201d is fixed on the surface of the support shaft 201c.

[0045] The fixed plate 201a is used to fix and support the support shaft 201c so that the support shaft 201c will not rotate with the rotating plate 103b. There are two drive seats 201d, which are arranged opposite to each other. As the rotating plate 103b rotates, the drive seats 201d can rotate relative to the rotating plate 103b.

[0046] Specifically, the swing member 201 also includes a support frame 201e, a fixed shaft 201f, a rocker arm 201g and a fixed seat 201h. The support frame 201e is fixed to one side of the rotating plate 103b, the fixed shaft 201f is fixed in the support frame 201e, the rocker arm 201g is rotatably connected to the surface of the fixed shaft 201f, and the fixed seat 201h is fixed to the end of the rocker arm 201g.

The fixed seat 201h is used to fix and support the gyroscope 104.

[0048] Specifically, the swing member 201 also includes a sliding ring 201i, a slider 201j, a rotating ball 201k, a positioning block 201l and a telescopic rod 201m.

[0049] The sliding ring 201i slides between the two driving seats 201d, and the slider 201j slides in the slot U to position the sliding ring 201i. The positioning block 201l slides in the rotating ball 201k to limit the sliding ring 201i and prevent the sliding ring 201i from rotating between the two driving seats 201d. The telescopic rod 201m is a diamond column, and the telescopic rod 201m slides in the swing rod 201g. When the rotating plate 103b rotates, the driving seat 201d can squeeze the sliding ring 201i, so that the sliding ring 201i drives the rotating ball 201k to move, so that the rotating ball 201k drives the swing rod 201g to swing through the telescopic rod 201m. At this time, the swing rod 201g can drive the gyroscope 104 to swing through the fixed seat 201h.

[0050] Example 2, reference Figures 1 to 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0051] Specifically, the clamping member 202 includes a lifting seat 202a, a first spring 202b, a hinge seat 202c, a hinge rod 202d, a sliding sleeve 202e, a sliding rod 202f, a second spring 202g, an extrusion block 202h, a support column 202i, a clamping rod 202j and a third spring 202k. The lifting seat 202a slides in the fixed seat 201h. The two ends of the first spring 202b are respectively fixed to the inner wall of the lifting seat 202a and the inner wall of the fixed seat 201h. The hinge seat 202c is fixed to one side of the lifting seat 202a. The hinge rod 202 d is hinged to two hinged seats 202c at both ends, the sliding sleeve 202e slides in the fixed seat 201h, the sliding rod 202f slides in the sliding sleeve 202e, the second spring 202g is fixed at both ends to the end of the sliding rod 202f and the inner wall of the sliding sleeve 202e, the extrusion block 202h is fixed to the other end of the sliding rod 202f, the support column 202i is fixed in the fixed seat 201h, the clamping rod 202j is rotatably connected to the surface of the support column 202i, and the third spring 202k is fixed at both ends to one side of the clamping rod 202j and the inner wall of the fixed seat 201h.

[0052] When the gyroscope 104 needs to be installed on the lifting seat 202a, the gyroscope 104 can be pressed so that the gyroscope 104 squeezes the lifting seat 202a, thereby pressing the lifting seat 202a into the fixed seat 201h, and the first spring 202b is in a compressed state, used to support the lifting seat 202a, and the other hinged seat 202c is fixed to the top of the sliding sleeve 202e. When the lifting seat 202a moves downward, the two sliding sleeves 202e can be pushed respectively by the two hinged rods 202d, so that the two sliding sleeves 202e push the sliding rod 202f through the second spring 202g, so that the two sliding rods 202f drive the two extrusion blocks 202h to move away from each other.

[0053] The support column 202i is used to support the clamping rod 202j, and the clamping rod 202j is used to fix and clamp the gyroscope 104. The third spring 202k is in a stretched state and is used to pull the end of the clamping rod 202j, so that the other end of the clamping rod 202j is away from the gyroscope 104, thereby releasing the clamping of the gyroscope 104.

[0054] Specifically, the trigger member 203 includes a fixed column 203a, an extrusion plate 203b, a push plate 203c, a lifting sleeve 203d, a fixed plate 203e, a fourth spring 203f, a lifting shell 203g, a connecting strip 203h and a fifth spring 203i. The fixed column 203a is fixed to one side of the support frame 201e, the extrusion plate 203b is fixed to the end of the fixed column 203a, the push plate 203c slides in the fixed seat 201h, the lifting sleeve 203d is fixed to the top of the push plate 203c, the fixed plate 203e is fixed in the fixed seat 201h, the two ends of the fourth spring 203f are respectively fixed to one side of the fixed plate 203e and the inner wall of the lifting sleeve 203d, the lifting shell 203g is fixed to the top of the lifting sleeve 203d, the connecting strip 203h slides in the lifting shell 203g, and the two ends of the fifth spring 203i are respectively fixed to the inner wall of the connecting strip 203h and the inner wall of the lifting shell 203g.

[0055] The fixed column 203a is used to fix and support the extrusion plate 203b, the extrusion plate 203b is used to extrude the push plate 203c, the lifting sleeve 203d is used to push the lifting shell 203g, the fourth spring 203f is in a compressed state, and the fifth spring 203i is in a compressed state. With the swing of the fixed seat 201h, the extrusion plate 203b can squeeze the push plate 203c, so that the push plate 203c moves into the fixed seat 201h. At this time, the push plate 203c can push the lifting shell 203g through the lifting sleeve 203d, so that the lifting shell 203g drives the connecting bar 203h to move.

[0056] Specifically, the reset member 204 includes a limit column 204a, a limit block 204b, a moving rod 204c, a connecting rod 204d, a sixth spring 204e, a push rod 204f, a push block 204g, an extrusion rod 204h, a push plate 204i, a seventh spring 204j, a positioning column 204k, a clamping plate 204l, a positioning rod 204m and a counterweight 204n. The limit column 204a is fixed to one side of the lifting seat 202a, the limit block 204b is located on one side of the limit column 204a, the moving rod 204c is fixed to one side of the limit block 204b, the connecting rod 204d is fixed between the two moving rods 204c, and both ends of the sixth spring 204e are fixed to the lifting seat 202a. They are respectively fixed to one side of the connecting rod 204d and the inner wall of the fixed seat 201h, the push rod 204f is fixed to the other end of the moving rod 204c, the push block 204g is fixed to the top of the connecting strip 203h, the extrusion rod 204h slides in the fixed seat 201h, the push plate 204i is fixed to the end of the extrusion rod 204h, the two ends of the seventh spring 204j are respectively fixed to one side of the push plate 204i and the inner wall of the fixed seat 201h, the positioning column 204k is fixed to the inner wall of the extrusion rod 204h, the clamping plate 204l is rotatably connected to the surface of the positioning column 204k, the positioning rod 204m is fixed in the extrusion rod 204h, and the counterweight block 204n is fixed to one side of the clamping plate 204l.

[0057] The sixth spring 204e is in a compressed state, and the seventh spring 204j is in a compressed state. When the gyroscope 104 is fixedly installed, the lifting seat 202a can drive the limiting column 204a to squeeze the limiting block 204b, so that the limiting block 204b pushes the connecting rod 204d to move through the moving rod 204c, so that the connecting rod 204d squeezes the sixth spring 204e. When the limiting column 204a moves to the bottom of the limiting block 204b, under the action of the reset elastic force of the sixth spring 204e, the sixth spring 204e can push the connecting rod 204d, so that the limiting block 204b is pushed through the moving rod 204c, so that the limiting block 204b is clamped and limited to the limiting column 204a, preventing the lifting seat 202a from moving to the outside of the fixed seat 201h under the action of the reset elastic force of the first spring 202b.

[0058] When the gyroscope 104 is located directly above the rotating plate 103b, the push plate 204i can be pressed, so that the push plate 204i squeezes the squeezing rod 204h. At this time, the card plate 204l moves to the side of the positioning rod 204m under the gravity of the counterweight block 204n. At this time, the card plate 204l is located inside the squeezing rod 204h, so that the squeezing rod 204h drives the card plate 204l to push the connecting bar 203h. At this time, the connecting bar 203h can push the push rod 204h through the push block 204g. 4f is pushed, so that the push rod 204f drives the two moving rods 204c to move, so that the limit block 204b releases the limit on the limit column 204a, and at this time, the lifting seat 202a can push the gyroscope 104 under the action of the reset elastic force of the first spring 202b. At this time, the two clamping rods 202j are bent to release the clamping rods 202j from fixing the gyroscope 104. At this time, the gyroscope 104 begins to separate from the fixed seat 201h under the push of the lifting seat 202a.

[0059] Specifically, first fix the gyroscope 104 to the top of the fixing base 201h;

[0060] Starting the driving motor 102c can drive the gyroscope 104 to perform circular motion in the horizontal direction;

[0061] Then, the rotating motor 103c is started to make the gyroscope 104 perform a circular motion in the vertical direction and at the same time, the gyroscope 104 performs a swing motion;

[0062] During the rotation process, the output signal of the gyroscope is collected in real time, and its changes over time are recorded;

[0063] Process and analyze the collected data to calculate the drift angular velocity of the gyroscope;

[0064] After the test is finished, the rotating plate 103b drives the gyroscope 104 to be located directly above, and then the gyroscope 104 can be removed.

[0065] During use, when the gyroscope 104 needs to be fixed, the gyroscope 104 can be pressed so that the gyroscope 104 squeezes the lifting seat 202a, thereby pressing the lifting seat 202a into the fixed seat 201h. When the lifting seat 202a moves downward, the two sliding sleeves 202e can be pushed respectively by the two hinged rods 202d, so that the two sliding sleeves 202e push the sliding rod 202f through the second spring 202g, so that the two sliding rods 202f drive the two squeezing blocks 202h away from each other. At this time, the squeezing block 202h can squeeze the end of the holding rod 202j, so that the other end of the clamping rod 202j fixes and clamps the gyroscope 104.

[0066] At this time, the driving motor 102c and the rotating motor 103c can be started, so that the driving motor 102c drives the rotating frame 102e to rotate horizontally, and the rotating motor 103c drives the rotating plate 103b to rotate vertically. When the rotating plate 103b rotates, the driving seat 201d can squeeze the sliding ring 201i, so that the sliding ring 201i drives the rotating ball 201k to move, so that the rotating ball 201k drives the pendulum 201g to swing through the telescopic rod 201m. At this time, the pendulum 201g can drive the gyroscope 104 to swing through the fixed seat 201h, so that the gyroscope 104 can be tested in multiple dimensions.

[0067] When the test is completed, the driving motor 102c and the rotating motor 103c are stopped, so that the gyroscope 104 is located directly above the rotating plate 103b. At this time, the squeezing plate 203b squeezes the push plate 203c, so that the push plate 203c moves into the fixed seat 201h. At this time, the push plate 203c can push the lifting shell 203g through the lifting sleeve 203d, so that the lifting shell 203g drives the connecting bar 203h to move, so that the connecting bar 203h moves to the side of the squeezing rod 204h, and presses the push plate 204i, so that the push plate 204i squeezes the squeezing rod 204h. At this time, the card plate 204l moves to the side of the positioning rod 204m under the gravity of the counterweight block 204n. At this time, the card plate 204l is located in the squeezing rod 204h, so that the squeezing rod 204h drives the card plate 204l to push the connecting bar 203h. At this time, the connecting bar 203h can push the push rod 204f through the push block 204g, so that the push rod 204f drives the two moving rods 204c to move, so that the limit block 204b releases the limit on the limit column 204a. At this time, under the action of the reset elastic force of the first spring 202b, the lifting seat 202a can push the gyroscope 104. At this time, the two clamping rods 202j are bent to release the fixation of the clamping rod 202j to the gyroscope 104. At this time, the gyroscope 104 begins to separate from the fixed seat 201h under the push of the lifting seat 202a, so as to ensure that when the gyroscope 104 is disassembled, the gyroscope 104 will be located directly above the rotating plate 103b to prevent the gyroscope 104 from falling.
