[0002] At present, there are many test items for inertial sensor products, and the test time is long. For a certain product to be tested, there are two threaded through holes on both sides of the product to be tested. The existing test method is to directly install a single set of products to be tested on the test equipment, that is, the temperature control rate turntable, through four screws. There are multiple connection holes on the temperature control rate turntable, and the rotation rate range is 0 to 350 degrees per second. The temperature control rate turntable is used in conjunction with a multi-channel test system to test a single set of products to be tested, and the test efficiency is low.

[0003] With the increasing demand for testing, it is necessary to design a fixture that can simultaneously install multiple sets of products to be tested and can be used in conjunction with existing test equipment. Utility Model Content

[0009] The product installation platform includes two installation rods and a connecting rod located between the two installation rods, and the installation rods and the connecting rod are parallel to each other;

[0010] The mounting rod is provided with a plurality of mounting holes, and the product to be tested is mounted on the product mounting table through fasteners;

[0011] The height of the support frame is greater than the height of the product to be tested, and the length of the support frame is greater than the width of the product to be tested;

[0012] The clamp can be mounted on the rate turntable in multiple positions by fasteners.

[0013] Furthermore, the support frame is in an "I" shape, and a support column perpendicular to the product installation platform is provided at each end.

[0014] Furthermore, a boss is provided on the mounting rod, and the boss matches with the side end surface of the product to be tested.

[0015] Furthermore, the mounting rods of the two product mounting platforms are arranged in parallel and staggered.

[0016] Further, the parallelism between the upper and lower surfaces of the product mounting table is less than 0.03 mm;

[0017] The flatness of the outer surface of the support frame is less than 0.03 mm.

[0018] Furthermore, the verticality between the upper surface and the lower surface of the two product mounting platforms and the outer surfaces of the two support frames is less than 0.03 mm.

[0019] The advantages of the utility model are:

[0020] 1. The utility model takes into account the spatial dimensions of the original test equipment (temperature control rate turntable), and cooperates with the multi-channel test system to achieve simultaneous measurement of multiple sets of products to be tested in multiple working directions within a limited size range, thereby improving the test efficiency of the products.

[0031] The following is a further detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments:

[0032] according to Figures 1 to 8 As shown, a fixture for a multi-channel test system is a cubic frame structure, including two parallel product mounting tables and two parallel support frames, and the product mounting tables are perpendicular to the support frames.

[0033] Since the product needs to be rotated during testing, the fixture cannot be too heavy. The utility model adopts a lightweight fixture design and a cubic frame structure to meet the testing requirements.

[0034] The product mounting platform is used to mount the product to be tested 3; the two product mounting platforms are respectively arranged at the top and bottom ends of the two support frames; the product mounting platform includes two mounting rods 7 and a connecting rod 8, and the mounting rods 7 and the connecting rods 8 are parallel to each other; the mounting rods 7 are used to mount the product to be tested, and the connecting rods 8 are used to improve the structural strength of the fixture;

[0035] like Figure 4 As shown, the mounting rods 7 of the two product mounting platforms are arranged in parallel and staggered; two threaded mounting holes are arranged on the end surface of the mounting rod 7, and the product 3 to be tested is installed on the mounting rod by passing through the threaded through holes of the product 3 to be tested by four fixing screws 2, and the size of the threaded mounting holes and the distance between the threaded mounting holes are matched with the mounting holes on the rate turntable;

[0036] The mounting rod 7 is provided with a boss, which cooperates with the side end surface of the product to be tested to limit the position of the product to be tested, thereby reducing the difficulty of installation;

[0037] Among them, Figure 1 As shown, the inner end surface of the mounting rod 7 on one product mounting platform is provided with a boss 5, and the outer end surface of the mounting rod 7 on the other product mounting platform is provided with a boss 5, which reduces the installation difficulty of the two products to be tested 3 being installed on the inner side of one product mounting platform and the outer side of the other product mounting platform respectively. The parallelism between the upper surface and the lower surface of the product mounting platform is less than 0.03mm.

[0038] like Figure 2As shown, the support frame is in the shape of an “I”, and a support column 6 perpendicular to the product mounting platform is provided at each end; the height of the support frame is greater than the height of the product to be tested, ensuring that the product to be tested 3 can be installed inside the fixture; the length of the support frame is greater than the width of the product mounting platform, leaving space for the misalignment of the two product mounting platforms; in order to leave space for the installation of the screwdriver for the installation positions of the two products to be tested, it is convenient for the installation and removal of the product to be tested 3. The flatness of the outer surface of the support frame is less than 0.03mm, and the verticality of the upper and lower surfaces of the two product mounting platforms to the outer surfaces of the two support frames is less than 0.03mm.

[0039] like Figure 1 , Figure 8 As shown, two screws are provided on the rate turntable, and two pressing plates 1 are installed on the rate turntable 4 by means of the screws. The fixture presses a product mounting platform onto the rate turntable 4 by means of the two pressing plates 1 provided on the rate turntable 4, which is called the first working position. Figure 1 or pressing one side of the two product mounting platforms onto the rate turntable 4 at the same time, which is called the second working position, such as Figure 8 As shown; or a support frame is pressed against the rate turntable 4, which is called the third working position (not shown); within a limited size range, two sets of products to be tested are measured simultaneously in three working directions, thereby improving the test efficiency.

[0040] The above description is only a specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present utility model, and these modifications or substitutions should be included in the protection scope of the present utility model.
