DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] As Figures 1 to 5 shown, a vehicle center speaker mask inspection tool includes a base 1 and a fixed seat 2 provided on the base 1. There are several fixed seats 2, and a placement groove 3 is installed on the several fixed seats 2. A plurality of positioning portions 5 for locking the speaker mask body 4 are also provided on the base 1. The plurality of positioning portions 5 are located below the placement groove 3. An installation seat 6 is also provided on the base 1. A turning plate 7 is hinged on the installation seat 6. A closing block 8 is installed on the upper part of the turning plate 7. An abutting block 9 is installed on the side end of the turning plate 7 on the installation seat 6. A detection gap is formed between the closing block 8 and the placement groove 3 and the speaker mask body 4.
[0019] In this embodiment, the positioning portion 5 includes a fixed head 51 and a locking head 52. The fixed head 51 is mounted on the base 1, and the locking head 52 is detachably mounted on the fixed head 51 through an adapter block 53. A jack 54 is provided on the locking head 52, and a fastening bolt 55 is arranged in the jack 54. The locking head 52 is detachably arranged. According to the model of the speaker mask body 4 to be inspected, the corresponding locking head 52 is replaced, so that the inspection tool can be adapted to the detection of various models of speaker mask bodies 4.
[0020] In this embodiment, the lower end of the speaker mask body 4 is inserted into a plurality of the jacks 54.
[0021] In this embodiment, the placement groove 3 is of a U-shaped structure and is detachably mounted on the fixed seat 2.
[0022] In this embodiment, a backing plate 10 for limiting the flipping plate 7 is provided on the mounting seat 6. By means of the backing plate 10, the flipping plate 7 is maintained at an appropriate flipped angle, so that the closing block 8 and the placement groove 3 are closed. A clearance is provided between the mounting seat 6 and the closing block 8 to avoid obstruction of the flipping of the flipping plate 7.
[0023] In this embodiment, a handle 11 is further mounted on the side end of the flipping plate 7 to facilitate the rapid loading and unloading of the inspection tool.
[0024] Working process and principle: During the use of the present utility model, first, the pressing block 9 is disassembled. An operator holds the handle 11 and flips the flipping plate 7 downward from the mounting seat 6, so that the closing block 8 and the placement groove 3 are separated, thereby making the placement groove 3 in an open state. The speaker mask body 4 to be measured is placed on a plurality of positioning portions 5. During this process, a plurality of card joints at the lower part of the speaker mask body 4 are respectively inserted into the respective jacks 54 and fixed and locked by the fastening bolts 55.
[0025] Then, the closing block 8 is flipped upward through the flipping plate 7 until the flipping plate 7 abuts against the backing plate 10. Immediately, the pressing block 9 is mounted on the mounting seat 6 to position the flipping plate 7. At this time, the edges of the closing block 8 and the placement groove 3 are closed, and a detection gap is formed between the closing block 8 and the placement groove 3 and the speaker mask body 4. Finally, the detection gap is measured by a suitable go-no-go gauge. If the larger end cannot be inserted into the detection gap and the smaller end can be inserted into the detection gap, it can be ensured that the later assembly process is not affected and it is a qualified product.
[0026] Based on the above, the utility model sets the placement groove 3 and the positioning part 5, and cooperates with the closing block 8 that can be limited and reversed. A plurality of clamping joints at the lower part of the speaker mask body 4 are respectively placed into the respective jacks 54, and are fixed and locked by the fastening bolts 55. Then, the flip plate 7 flips the closing block 8 upward, so that the closing block 8 closes with the edge of the placement groove 3. Finally, the go-no-go gauge is used to directly measure the detection gap formed between the closing block 8 and the placement groove 3 and the speaker mask body 4, which is efficient, convenient and can avoid possible measurement errors.
[0027] As is known by technical common sense, the utility model can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not exclusive. All changes within the scope of the utility model or within the scope equivalent to the utility model are encompassed by the utility model.
