Abstract
The utility model discloses a fixture for fixing an IGBT (insulated gate bipolar translator) module in a mechanical shock test. The fixture comprises a rectangular fixed plate, wherein IGBT module mounting holes and fixing mounting holes for fixing the fixture on a test-bed mounting tabletop during the shock test on the IGBT module in the Z direction are formed in the rectangular fixed plate, wherein fixing blocks for fixing the fixture on the test-bed mounting tabletop during the shock test on the IGBT module in the X direction and the Y direction are respectively fixed on four side edges of the rectangular fixed plate. The fixture disclosed by the utility model is simple in structure and convenient to use; in the mechanical shock test, the IGBT module is not required to be dismounted from the fixture after the shock test in one direction is implemented, and only the direction of the fixture is switched; therefore, the fixture disclosed by the utility model can meet requirements of the mechanical shock test on the IGBT module in six directions.
Description
Technical field
The utility model relates to IGBT device for fixing module, particularly the fixing frock of IGBT module in a kind of mechanical shock test.
Background technology
IGBT module size is from 190 mm * 48, mm * 140 mm to 73 mm * 38, mm * 140 mm, the about 500g～3000g of weight, and according to IEC Standard 68-2-27 standard, need to be to IGBT module X, Y, each axle of Z carries out repeatedly mechanical shock test.
Mechanical shock test's platform can only carry out the motion of a direction, and the impact test of IGBT module need to be considered multidirectional mechanical shock.As shown in Fig. 1-Fig. 3, use now the frock 7 in strap bolt hole 8 that module is fixed on testing stand 9, that need to carry out test specimen repeatedly dismantles and installs the mechanical shock that just can complete XYZ six direction, and this frock is installed the damage that the mechanical stress producing may cause test specimen.
Summary of the invention
Technical problem to be solved in the utility model is; not enough for prior art; the fixedly frock of IGBT module is provided in a kind of mechanical shock test; that solve to use that existing frock need to carry out test specimen repeatedly dismantles and installs the problem that just can complete the mechanical shock test of XYZ six direction, and protection is for the IGBT module of impact test.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the fixing frock of IGBT module in a kind of mechanical shock test, comprise rectangle fixed head, on described rectangle fixed head, offer IGBT module installing hole and frock is fixed on when IGBT module is carried out to the impact test in Z direction to testing stand the fixed installation hole on table top is installed, on four sides of described rectangle fixed head, be fixed with respectively and frock be fixed on to testing stand when IGBT module is carried out to the impact test in directions X and Y-direction the fixed block on table top is installed.
On described fixed block, offer two above locating slots, better frock is fixed on to testing stand and installs on table top.
Described locating slot is U-shaped, facilitates frock dismounting.
Described fixed block length is identical with described rectangle fixed head side edge length, and while guaranteeing IGBT module to carry out the impact test in directions X and Y-direction, frock can firmly be fixed on testing stand and install on table top.
Compared with prior art, the beneficial effect that the utility model has is: tool structure of the present utility model is simple, easy to use; When carrying out mechanical shock test, complete after an impact test in direction, do not need IGBT module to disassemble from frock, as long as the direction of conversion frock, frock of the present utility model can meet IGBT module six direction Shang mechanical shock test demand; Protection IGBT module is avoided the damage that frock is installed the mechanical stress producing.
Accompanying drawing explanation
Fig. 1 utilizes existing frock to carry out the impact test schematic diagram in Z direction;
Fig. 2 utilizes existing frock to carry out the impact test schematic diagram on directions X;
Fig. 3 utilizes existing frock to carry out the impact test schematic diagram in Y-direction;
Fig. 4 is the utility model one example structure schematic diagram;
Fig. 5 is that IGBT module is arranged on the schematic diagram in the utility model embodiment frock.
The specific embodiment
As shown in Figure 4, the utility model one embodiment comprises rectangle fixed head 1, on described rectangle fixed head 1, offer IGBT module installing hole 2 and frock is fixed on when IGBT module is carried out to the impact test in Z direction to testing stand the fixed installation hole 3 on table top is installed, on 1 four sides of described rectangle fixed head, be fixed with respectively and frock be fixed on to testing stand when IGBT module is carried out to the impact test in directions X and Y-direction the fixed block 4 on table top is installed; On each fixed block 4, offer three locating slots 5, fixed block 4 length are identical with described rectangle fixed head 1 side edge length.
Locating slot 5 is designed to U-shaped, when needs disassembling fixture, only the screw in locating slot need to be unscrewed, and then frock is shifted out, and does not need screw all to disassemble, and makes the dismounting of frock more efficient and convenient.
As shown in Figure 5, the substrate one of IGBT module 6 faces down, and after the fixing hole on substrate side is aimed at IGBT module installing hole 2, is screwed.
The use procedure of the present embodiment frock is as follows:
1, IGBT module is fixed on to (as Fig. 5) in frock;
2, frock is fixed on to testing stand by fixed installation hole 3 and installs on table top, carry out the impact test in direction of Z axis;
3, disassembling fixture, tips upside down on testing stand by frock and installs on table top, with long spiro nail, by fixed installation hole 3, frock is fixed on testing stand, carries out the impact test in another direction of Z axis;
4, disassembling fixture, is vertically placed on testing stand by frock and installs on table top, in U-shaped locating slot, is screwed into screw, carries out the impact test in directions X or Y-direction;
5, the rest may be inferred, until complete the impact test on six direction.
