Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.
As shown in fig. 1-4, the embodiment of the present invention includes:
the utility model provides a vibration test is to fixed tool perpendicularly, includes transverse location board 1, longitudinal slab mounting hole 2, longitudinal location board 3, longitudinal plate equipment hole 4, transverse location board 1 is provided with one row of longitudinal slab mounting hole 2 along the central line, longitudinal location board 3 sets up perpendicularly on the transverse location board 1, the vertical direction of longitudinal location board 3 is provided with a plurality of longitudinal and transverse plate equipment holes 4 that run through, insert locking bolt 5 in the longitudinal plate equipment hole 4 and realize the fixed connection of longitudinal location board 3 and transverse location board 1 in threaded connection to longitudinal slab mounting hole 2.
And the longitudinal positioning plate 3 is provided with a vibration test prototype positioning hole 6 with the hole opening direction parallel to the transverse positioning plate 1.
Further, an edge of the longitudinal positioning plate 3 is cut into an oblique corner edge 7.
Further, the oblique corner edge 7 is 45 degrees.
Further, the positioning holes 6 of the vibration test prototype are arranged in a matrix structure.
Further, the matrix structure is a 3 × 6 structure.
A preferred embodiment is:
in the vibration test of the mobile phone, the regulation requires that the three orthogonal surfaces of a prototype are respectively subjected to the vibration test. Since the operation table of the vibration meter is small, if a vertical operation surface is welded on the operation table, the fixture of the prototype in the horizontal state is influenced, so that a jig which can be disassembled and assembled, is vertical to the operation table and can rigidly fix the prototype is required to be manufactured.
The specification can be designed as:
1. the vertical direction fixing jig:
the length and thickness of the table are the same as those of the plane table, and the height is 1/2.
The bearing of the vibration instrument is limited, so the size of the jig is not suitable to be too large.
2. Fixing screws:
the outer diameter of the harness cord is determined according to the harness cord planting on a horizontal operating platform of a vibration instrument, and the length is the harness cord planting depth, the height of the vertical operating platform, the thickness of the gasket, the thickness of the nut and the allowance (the allowance needs to be reserved for fixing firmly, the allowance is not too large for convenient operation, and 2min is recommended) the nut and the gasket are determined according to the specification of the harness cord. In addition, in order to keep the balance of the vibration meter, the jig needs to be fixed in the center of the operating platform, and the fixing screw holes in the jig can be punched thoroughly, so that a prototype can be fixed more conveniently, and the front side and the back side of the jig do not need to be distinguished. The vibration meter has limited load bearing, so the metal density is not suitable to be too high.
The specific operation is that the operation is,
1. testing the vibration of the lateral force of the mobile phone screen/back cover, enabling the mobile phone screen/back cover to face the board surface, and starting a vibration testing machine;
2. the mobile phone data line interface, the power supply button side and the loudspeaker side are extremely narrow and cannot be directly placed on a traditional vibration testing machine. Therefore, the back shell surface of the mobile phone faces the longitudinal positioning plate 3 by the device, the mobile phone is fixed on the longitudinal positioning plate 3, and the narrow surface of the narrower loudspeaker output port/key side of the mobile phone points to the transverse positioning plate 1. And finally, a vertical vibration test is realized.
The harness cord is fixed on the plane operation table firstly, and then the jig is placed in contrast to the harness cord, so that the jig is more convenient to install.
Wherein, the plate edge sets up bevel angle or fillet, can effectively prevent to hit personnel and take place the incident.
To sum up, the utility model provides a vibration test is perpendicular to fixed tool can only test the problem of single one side to traditional vibration test machine, increases longitudinal positioning board 3, effectively realizes the perpendicular to vibration test to the testee, and the tool has advantages such as simple structure, convenient operation, can highly adapt to perpendicularly to vibration test.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
