In order to make the first clamping unit 41 and the second clamping unit 42 horizontally symmetrically arranged at two ends of the fuse 100 in the longitudinal direction for matching, in this embodiment, the top of the first longitudinal positioning member 2 is concavely formed with the mounting table 22, and the first clamping unit 41 is mounted on the mounting table 22 through the longitudinal adjustment unit so that the first clamping unit 41 is flush with the top surface of the second clamping unit 42.

The wide positioning assembly is disposed between the two longitudinal positioning members 2 and is configured to be slidable in the width direction of the mount 1 to approach or separate from the fuse 100, and includes two wide positioning members 3 disposed parallel to each other, and the two wide positioning members 3 are disposed on the same side of the mount 1 in the width direction.

In detail, the bottom of the first longitudinal positioning member 2 protrudes toward the second longitudinal positioning member 2 to form a receiving table 21, and the first wide positioning member 3 and the first longitudinal positioning member 2 are fixed by the first limiting member 81.

The wide-direction clamping assembly comprises two third clamping units 91 and two positioning columns 92 which are arranged one by one with the two third clamping units 91, the two third clamping units 91 are arranged one by one on the two wide-direction positioning pieces 3, the two positioning columns 92 are arranged one by one on the tops of the two longitudinal positioning pieces 2, and the two third clamping units 91 are configured to slide along the width direction so as to be close to or far away from the corresponding positioning columns 92.

In this embodiment, the wide positioning member 3 includes a fixing base 31 disposed along a width direction, a mating block 32 slidably disposed on a top of the fixing base 31, and a second limiting member 82 for limiting a position of the fixing base 31 and the mating block 32 relative to each other in a longitudinal direction, and the third clamping unit 91 is slidably disposed on the mating block 32.

Specifically, the third clamping unit 91 includes a slider 911 slidably disposed on top of the mating block 32, a holding block 912 disposed on a side of the slider 911 near the fuse 100, and a third stopper 83 for restricting a widthwise relative position of the slider 911 and the mating block 32.

It should be noted that, the holding block 912 and the positioning column 92 corresponding thereto are respectively disposed at two sides of the corresponding contact blade 30 in the width direction, that is, when the fuse 100 is clamped, the positioning column 92 is held against one second edge of the corresponding contact blade 30, and the holding block 912 is driven by the fourth sliding structure 54 and the fifth sliding structure 55 to move toward the corresponding positioning column 92 until the holding block 912 is held against the other second edge of the corresponding contact blade 30, so as to clamp the fuse 100 in the width direction in cooperation with the corresponding positioning column 92.

Since the fuse 100 is straddled over the first and second longitudinal positioning members 2 and 2 when the fuse 100 is clamped, in order to ensure the contact stability between the holding block 912 and the second side of the contact blade 30, at least part of the holding block 912 is higher than the longitudinal positioning member 2, and the heights of the first and second longitudinal positioning members 2 and 2 are the same, so as to avoid the fuse 100 from being not placed horizontally, thereby affecting the detection result.

Specifically, the holding block 912 includes a main body portion 9121 fixed on the sliding block 911 and a protruding portion 9122 protruding from the main body portion 9121 toward the corresponding positioning post 92, in the width direction, the front projection of the positioning post 92 overlaps or substantially overlaps with the front projection of the corresponding protruding portion 9122, and the surfaces of the positioning post 92 and the protruding portion 9122 for contacting the fuse 100 are arc surfaces.

The surface of the positioning column 92 and the protruding portion 9122, which is used for being contacted with the second side of the corresponding contact blade 30, is set to be an arc surface, so that the contact of the positioning column 92 and the protruding portion 9122 with the second side is changed from surface contact to line contact, the contact area is reduced, and the influence on the levelness detection result of the contact blade 30 is avoided.

Taking this embodiment as an example, the working flow of the multi-product flatness detection compatible jig of the present utility model is as follows: the longitudinal positioning component and the wide positioning component of the jig are adjusted according to the longitudinal dimension and the wide dimension of the fuse 100 to be detected, the first limiting piece 81 is manually adjusted to adjust the distance between the first longitudinal positioning piece 2 and the second longitudinal positioning piece 2 through the sliding structure 7, and meanwhile, the two second limiting pieces 82 are manually adjusted to adjust the distance between the third clamping unit 91 and the positioning column 92 through the two fourth sliding structures 54 so as to adapt to the dimension of the fuse 100 to be detected.

Then, the fuse 100 is spanned to the top of the first and second longitudinal positioning members 2 and 2, so that the two contact blades 30 of the fuse 100 are respectively positioned in the space defined by the holding block 912, the first clamping block 411 and the positioning column 92 corresponding to the first clamping block 411 provided on the first wide positioning member 3, and the space defined by the holding block 912, the second clamping block 421 and the positioning column 92 corresponding to the second clamping block 421 provided on the second wide positioning member 3.

Next, the distance between the mating block 32 and the sliding block 911 in the width direction is automatically adjusted by the two third limiting members 83 and the two fifth sliding structures 55, so that the supporting block 912 and the corresponding positioning post 92 are respectively supported on the two second edges of the contact blade 30 to clamp the fuse 100 in the width direction, and the fourth limiting member 84 and the fifth limiting member 85 are continuously manually adjusted, so that the first clamping unit 41 and the second clamping unit 42 are respectively adjusted in the width direction by the first sliding structure 51 and the second sliding structure 52, and the first clamping block 411 and the second clamping block 421 are respectively positioned at two ends of the fuse 100 in the longitudinal direction and at the midpoint of the width direction.

Finally, the sixth limiting member 86 and the third sliding structure 53 automatically adjust the relative distance between the first clamping unit 41 and the second clamping unit 42 in the longitudinal direction, and the first clamping unit 41 slides towards the second clamping unit 42 until the first clamping block 411 and the second clamping block 421 respectively abut against the first edges of the two contact blades 30, so as to clamp the fuse 100 in the longitudinal direction, thereby realizing positioning of the fuse 100.

It should be noted that, in other optional embodiments, the first limiting member 81, the second limiting member 82, the third limiting member 83, the fourth limiting member 84, the fifth limiting member 85 and the sixth limiting member 86 may all be an electric sliding table, and the jig may be further provided with a controller to control the working states of the first limiting member 81, the second limiting member 82, the third limiting member 83, the fourth limiting member 84, the fifth limiting member 85 and the sixth limiting member 86, and the controller may be disposed on the jig, and may be implemented by a single chip microcomputer or a logic circuit, or may be an external control device, such as a computer or a mobile phone, and is connected with the first limiting member 81, the second limiting member 82, the third limiting member 83, the fourth limiting member 84, the fifth limiting member 85 and the sixth limiting member 86 through signals, which is not repeated herein.
