Description

Technical Field

[0001] The utility model relates to the technical field of fixture locking, and in particular to a modular quick-locking mechanism of an IMU batch calibration fixture. Background Art

[0002] The IMU batch calibration fixture is a device specially designed for calibrating multiple IMUs at the same time. By precisely controlling the placement and posture of the IMU, the fixture can ensure that each IMU is affected by the same external conditions during the calibration process, thereby eliminating individual differences and improving the consistency of the calibration results. During the IMU batch calibration process, the tray is used as a carrier for the IMU, and its stability and accuracy are also critical. At present, most trays on the market are designed to be placed in the fixture frame and fixed with screws;

[0003] The method of locking the pallet with screws requires tightening or loosening multiple screws one by one, which is inconvenient for assembly and disassembly. In addition, the screw connection may become loose after long-term operation or under the influence of environmental factors. However, the current fixing method is not equipped with an effective early warning mechanism to monitor the status of the pallet in real time. Once the pallet is loose, its impact may not be immediately detected, resulting in distortion of the calibration data.

[0004] In order to solve the above problems, this application proposes a modular quick-lock mechanism for an IMU batch calibration fixture. Utility Model Content

[0008] Several of the sockets are inserted with locking pieces, and the several locking pieces are used to press and release objects on several load-bearing blocks respectively;

Connecting rods are installed at both ends of the reset handle member, and a pressing member is installed at the bottom end of the connecting rod, and the pressing member passes through the socket to press the object on the load-bearing block.

[0011] Preferably, the reset handle member includes a rotating rod, a U-shaped block, a torsion spring and a handle, the middle parts of the two protrusions are provided with a through hole, the rotating rod rotates horizontally through the two through holes, the U-shaped block is fixedly mounted on the rotating rod, an opening is formed in the U-shaped block, the two protrusions are located in the opening, the handle is installed on the top of the U-shaped block, the torsion spring is sleeved on the rotating rod and located between the two protrusions, the two ends of the torsion spring are respectively connected to a protrusion and the handle, and the two connecting rods are respectively installed at the two ends of the rotating rod.

[0012] Preferably, the pressing piece includes a pressing rod and a pressing block, there are two pressing rods, one end of the two pressing rods are respectively connected to the bottom ends of the two connecting rods, the two pressing rods pass through the sockets, and the pressing block is installed at the other end of the two pressing rods and is located above one of the bearing bars.

[0013] Preferably, the pressure warning component includes a pressure sensor and an alarm, the pressure sensor is installed at the bottom of the pressure block, the alarm is installed on the side of one of the connecting rods, and the pressure sensor is electrically connected to the alarm.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] Through the provided locking parts, the pallet can be placed on the two corresponding bearing bars on the inner walls of both sides of the jig frame, and then the pallet can be pressed and limited by the locking parts to achieve quick locking of the pallet. When disassembling it, it is only necessary to release the limit of the pallet by the locking parts. This structure locks and unlocks the pallet by the locking parts, making it easy to disassemble and assemble it.

[0016] By setting a pressure warning part, when the pallet is limited by the locking part, the pressure warning part on the locking part can be pressed tightly against the pallet. When the pallet becomes loose, the pressure on the pressure warning part will change immediately, and the pressure warning part can be used to give an alarm in time. This structure can give an alarm in time after the pallet becomes loose. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-4 As shown, the modular quick-lock mechanism of an IMU batch calibration fixture proposed in the utility model includes a fixture frame 1;

[0024] In this embodiment, a plurality of spaced-apart bearing bars 2 are installed on the inner walls of both sides of the jig frame 1 , and a plurality of sockets are opened on both sides of the jig frame 1 , and the plurality of sockets are respectively located above the plurality of bearing bars 2 .

[0025] In this embodiment, a plurality of sockets are inserted with locking members 3, and the plurality of locking members 3 are respectively used to press and release objects on the plurality of bearing bars 2. The locking members 3 include locking brackets 31, and a plurality of sockets are provided on both sides of the fixture frame 1, and the plurality of sockets are respectively located above the plurality of sockets. The locking brackets 31 are provided with insertion rods 36 inserted in the sockets, and the sides of the locking brackets 31 are provided with two protrusions 32, and the two protrusions 32 are provided with reset handles 33, and the two ends of the reset handles 33 are provided with connecting rods 34, and the bottom end of the connecting rods 34 is provided with pressing members 35, and the pressing members 35 pass through the sockets to press the objects on the bearing bars 2. The reset handle member 33 includes a rotating rod 331, a U-shaped block 332, a torsion spring 333 and a handle 334. A through hole is provided in the middle of the two protrusions 32. The rotating rod 331 rotates horizontally through the two through holes. The U-shaped block 332 is fixedly mounted on the rotating rod 331. An opening is formed in the U-shaped block 332. The two protrusions 32 are located in the opening. The handle 334 is installed on the top of the U-shaped block 332. The torsion spring 333 is sleeved on the rotating rod 331 and is located between the two protrusions 32. The two ends of the torsion spring 333 are respectively connected to a protrusion 32 and the handle 334. The two connecting rods 34 are respectively installed at the two ends of the rotating rod 331. The pressing piece 35 includes a pressing rod 351 and a pressing block 352. There are two pressing rods 351. One end of the two pressing rods 351 is respectively connected to the bottom end of the two connecting rods 34. The two pressing rods 351 pass through the socket. The pressing block 352 is installed at the other end of the two pressing rods 351 and is located above one of the bearing bars 2.

[0026] In this embodiment, a pressure warning member 4 that is pressed against an object is installed on the lock member 3. The pressure warning member 4 includes a pressure sensor 41 and an alarm 42. The pressure sensor 41 is installed at the bottom of the pressing block 352, and the alarm 42 is installed on the side of a connecting rod 34. The pressure sensor 41 and the alarm 42 are electrically connected.

[0027] It should be noted that: applying pressure to the handle 334 can transmit the force to the connecting rod 34 and the pressure rod 351 through the rotating rod 331, so that the pressure block 352 on the pressure rod 351 can be lifted, and then the pallet is placed on the two corresponding bearing bars 2 on the inner walls of the two sides of the fixture frame 1, and then the pressure applied to the handle 334 is cancelled. Under the action of the torsion spring 333, the rotating rod 331, the connecting rod 34, the pressure rod 351 and the pressure block 352 can be restored to their original positions, so that the pressure block 352 is pressed against the pallet to achieve quick locking of the pallet. When disassembling the pallet, it is only necessary to apply pressure to the handle 334 and lift the pressure block 352 to release the limit on the pallet. This structure locks and unlocks the pallet through the locking member 3, which is convenient for disassembly and assembly.

[0028] When the pressure block 352 is pressed against the pallet, the pressure sensor 41 at the bottom of the pressure block 352 can be pressed against the pallet. When the pallet becomes loose, the pressure on the pressure sensor 41 will change immediately, and the pressure signal will be transmitted to the alarm 42. The alarm 42 can be used to give an alarm in time. This structure can give an early warning when the pallet becomes loose.
