In an embodiment of the present utility model, a housing shape deformation measuring jig 100 is provided for detecting deformation of a conventional electronic product housing. The to-be-measured housing 200 includes, but is not limited to, a housing of an electronic product such as a mobile phone, a tablet computer, and the like.

As shown in fig. 1-5, the housing shape deformation measuring jig 100 includes a base 10, and a profiling jig 20, a first measuring assembly 30 and a second measuring assembly 40 all disposed on the base 10. The base 10 includes a table top 11 and four support columns 12, and the four support columns 12 support the table top 11, so that the table top suspension 11 is empty.

In this embodiment, the profiling jig 20 includes a rectangular fixing block 21 fixed on the table top 11, and the fixing block 21 is used for placing the housing 200 to be measured. The length and width dimensions of the housing 200 to be measured are all smaller than or equal to the length and width dimensions of the fixed block 21. The fixed block 21 is provided with at least one suction nozzle 22, and the suction nozzle 22 is used for sucking the housing 200 to be measured placed on the fixed block 21 by generating negative pressure. In the present embodiment, the suction nozzles 22 are hydraulic suction nozzles, and the number of the suction nozzles is two, so as to improve the stability of fixing the housing 200 to be measured.

Specifically, the first measuring assembly 30 includes a first driving portion 31 disposed on the base 10 and a first micrometer 32 disposed on the first driving portion 31. The second measuring unit 40 includes a second driving part 41 provided on the base 10 and a second micrometer 42 provided on the second driving part 41. The first driving portion 31 is configured to drive the first micrometer 32 to measure the deformation of the first side 201 of the housing 200 to be measured, and the second driving portion 41 is configured to drive the second micrometer 42 to measure the deformation of the second side 202 of the housing 200 to be measured. The first side 201 and the second side 202 may be disposed at an angle, for example, perpendicular to each other. In the present embodiment, the first micrometer 32 and the second micrometer 42 are both digital display micrometers, so as to quickly learn the deformation value obtained by current measurement.

For example, the first side 201 is a short side of the housing 200 to be measured, and the second side 202 is a long side of the housing 200 to be measured. The first driving part 31 drives the measuring end of the first micrometer 32 to abut against the short side of the casing 200 to be measured, the second driving part 41 drives the measuring end of the second micrometer 42 to abut against the long side of the casing 200 to be measured, so that the dimension parameter of the corresponding position of the casing 200 to be measured can be measured, and then the dimension parameter is compared according to the preset standard dimension parameter to obtain the deformation of the position. Therefore, the deformation of the shell 2 in two directions can be measured simultaneously by the technical scheme, and the measurement efficiency is effectively improved. It should be noted that the working principle and specific structure of the digital display micrometer can refer to the prior art, and the utility model is not limited herein.

Further, in one embodiment, the first driving portion 31 includes a first flat pushing cylinder 311 fixed on the base 10 and a first slider 312 provided on the first flat pushing cylinder 311, and the first micrometer 32 is vertically fixed on the first slider 312. The first flat pushing cylinder 311 is used for driving the first slider 312 to slide along the horizontal direction, so that the first micrometer 32 is close to or far from the profiling fixture 20. That is, when measurement is required, the first flat pushing cylinder 311 drives the first micrometer 32 to approach the profiling fixture 20, so that the measurement end of the first micrometer 32 abuts against the preset position of the housing 200 to be measured; when the measurement is completed, the first flat pushing cylinder 311 drives the first micrometer 32 away from the profiling jig 20 so as to replace the new housing 200 to be measured.

Further, the base 10 is provided with a pair of first sliding rails 313 disposed in parallel and spaced apart from each other, and two sides of the first sliding block 312 are slidably connected to the pair of first sliding rails 313 respectively. Therefore, the first sliding rail 313 limits the movement of the first sliding block 312 on the base 10, so as to avoid the first sliding block 312 from traversing, and reduce the resistance of the first sliding block 312 during movement.

Further, the base 10 is provided with a first avoiding hole 13. The first horizontal pushing cylinder 311 is fixed on one side of the base 10 away from the profiling fixture 20, and is fixedly connected with the first slider 312 through a first connecting block 314 passing through the first avoiding hole 13. Specifically, the first horizontal pushing cylinder 311 is fixed on the bottom surface of the base 10, so that the space of the base 10 is fully utilized, and the volume of the whole jig is reduced. In addition, the first connecting block 314 passes through the first avoiding hole 13, and the upper and lower ends thereof are respectively fixed on the first slider 312 and the first flat pushing cylinder 311, and can reciprocate in the first avoiding hole 13 along the direction parallel to the first sliding rail 313.

Further, a first cushion block 315 is further disposed on a side of the base 10 facing away from the profiling fixture 20. The first flat pushing cylinder 311 is fixed to a side of the first pad 315 facing away from the base 10, thereby raising the height of the first flat pushing cylinder 311 relative to the table top 11 of the base 10. The first connecting block 314 is provided with a first buffer 316, and when the first horizontal pushing cylinder 311 drives the first connecting block 314 to reach a preset position, the first buffer 316 abuts against the first cushion block 315. It should be noted that, first, the first buffer member 316 can buffer the movement of the first connecting block 314 and the first slider 312, so as to avoid the first micrometer 32 from directly and quickly striking the side surface of the housing 200 to be detected, thereby causing inaccurate measurement and even damage to the first micrometer 32; secondly, when the first micrometer 32 is near to the side of the housing 200 to be detected, the first buffer member 316 abuts against the first cushion block 315, so as to damp and reduce the movement of the first slider 312, so that the first micrometer 32 can slowly approach to the side of the housing 200 to be detected, and the measurement accuracy is improved.

In one embodiment, the second driving part 41 includes a second flat pushing cylinder 411 fixed on the base 10 and a second slider 412 disposed on the second flat pushing cylinder 411, and the second micrometer 42 is vertically fixed on the second slider 412. The second flat pushing cylinder 411 is used for driving the second slider 412 to slide along the horizontal direction, so that the second micrometer 42 approaches or moves away from the profiling fixture 20.

Further, the base 10 is further provided with a pair of second sliding rails 413 disposed in parallel and spaced apart, and two sides of the second sliding block 412 are respectively slidably connected to the pair of second sliding rails 413; the first sliding rail 313 is perpendicular to the second sliding rail 413.

Further, the base 10 is further provided with a second avoiding hole 14. The second flat pushing cylinder 411 is fixed on one side of the base 10 away from the profiling fixture 20, and is fixedly connected with the second slider 412 through a second connecting block 414 passing through the second avoiding hole 14.

Further, a second cushion block 415 is further disposed on a side of the base 10 facing away from the profiling fixture 20. The second flat pushing cylinder 411 is fixed on one side of the second cushion block 415 away from the base 10; the second connecting block 414 is provided with a second buffer element 416, and when the second flat pushing cylinder 411 drives the second connecting block 414 to reach a preset position, the second buffer element 416 abuts against the second cushion block 415.

Note that, the implementation principle and function of each component in the second driving portion 41 may refer to each corresponding component in the first driving portion 31, so that a description thereof is omitted.

In one embodiment, the number of first micrometer 32 and second micrometer 42 is plural. The first micrometer 32 is disposed on the first driving portion 31 at intervals, that is, the first micrometer 32 is fixed on the first slider 312 at equal intervals. It should be noted that, since the initial positions are the same, the instrument panel of the first micrometer 32 is cleared, the probe contacts the corresponding side of the housing 200 to be measured, the plurality of first micrometers 32 contact the side, then the first sliding block 312 stops, the readings of the first micrometers 32 are recorded, and meanwhile, the differences of a plurality of point values are compared (wherein, the micrometers have a certain movable stroke and cannot cause a top dead state due to the differences of the deformation), namely, the deformation of each section of the same side of the housing is obtained, thereby accurately locking the deformation position and the deformation of the housing 200 to be measured. Based on the same principle, the plurality of second micrometer 42 are distributed on the second driving portion 41 at intervals, that is, the plurality of second micrometer 42 are fixed on the second slider 412 at equal intervals.

Therefore, one side of the housing 200 to be measured can drive a plurality of micrometers to measure through a flat pushing cylinder, so that the deformation of the side edge in a multi-section position can be measured simultaneously, and the accuracy is higher.

Further, a first stop block 23 is provided on a side of the fixed block 21 away from the first micrometer 32, and a second stop block 24 is provided on a side of the fixed block 21 away from the second micrometer 42. When the housing to be measured 200 is placed on the fixed block 21, a side of the housing to be measured 200 away from the first side 201 abuts against the first stop block 23, and a side of the housing to be measured 200 away from the second side 202 abuts against the second stop block 24. I.e. the first stop 23 and the second stop 24 can provide a supporting force for the housing 200 to be measured and position the housing 200 to be measured on the fixed block 21.

Further, a first avoidance groove 25 into which the first micrometer 32 extends is formed in one side of the fixed block 21, which is close to the first micrometer 32, and a second avoidance groove 26 into which the second micrometer 42 extends is formed in one side of the fixed block 21, which is close to the second micrometer 42. When the housing 200 to be measured is placed on the fixed block 21, if the area of the housing is smaller than the fixed block 21, the first micrometer 32 and the second micrometer 42 can extend into the area of the fixed block 21 to measure the housing.

In summary, according to the housing shape deformation measuring jig 100 provided by the utility model, the housing 200 to be measured is placed on the profiling jig 20, so that the first driving portion 31 can drive the first micrometer 32 to measure the deformation degree of the preset portion of the first side 201, and the second driving portion 41 can drive the second micrometer 42 to measure the deformation degree of the preset portion of the second side 202, thereby realizing simultaneous measurement of multiple sides of the housing 200 to be measured, improving the measurement efficiency, and having small occupied volume, and meeting the detection requirements of normal mass production type full detection size and product deformation amount.
