[0035] like Figures 1 to 12 As shown, the yarn feeder inspection fixture provided in this embodiment includes a base 1, a slider 2, a mounting bracket 3, a dial indicator 4, a first positioning component 5, and a second positioning component 6. The left side wall and the left side of the front side wall of the base 1 each have a sliding groove 7. A slider 2 is slidably connected within the sliding groove 7. A mounting bracket 3 is detachably fixed to the top of each slider 2. A dial indicator 4 is fixed to the top of each mounting bracket 3. The top of the base 1 has a placement groove 8 for placing the yarn feeder 10. The first positioning component 5 and the second positioning component 6 are both located on the top of the base 1, and both are located behind the placement groove 8. The first positioning component 5 is located to the left of the second positioning component 6. Before inspection, the prepared standard yarn feeder is installed, and the two dial indicators 4 are zeroed. The dimensions of the standard yarn feeder are consistent with the precision dimensions of the yarn feeder being inspected. After zeroing, remove the standard yarn feeder and place the assembled yarn feeder 10 into the placement slot 8. Then, push the yarn feeder 10 from left to right until the ceramic head of the yarn feeder 10 abuts against the left end wall of the placement slot 8. Position the yarn feeder 10 using the first positioning component 5 and the second positioning component 6. Then, push the mounting bracket 3 located on the front side of the base 1 left and right, causing the dial indicator 4 on it to move left and right. Push the mounting bracket 3 located on the left side of the base 1 back and forth, causing the dial indicator 4 on it to move back and forth. When the dial indicator 4 contacts the yarn feeder 10, the amount of fluctuation in the dial indicator 4's value during its movement is the assembly error. Observe the value change; values ​​exceeding the specified range indicate a defective product. By using the dial indicator 4, combined with the cooperation of the slider 2 and the slide groove 7, and positioning by the first positioning component 5 and the second positioning component 6, the inspection accuracy is high. After inspection, push the dial indicator 4 located at the front to the left and push the dial indicator 4 located on the left side backward to remove the positioning of the first positioning part 5 and the second positioning part 6. Then the yarn feeder 10 can be removed. In this way, high-precision inspection of the yarn feeder 10 can be achieved through simple operation. Furthermore, the detachable mounting bracket 3 facilitates the maintenance and replacement of the dial indicator 4.

[0036] The mounting bracket 3 includes a horizontal plate 31, a locking block 32, and a column 33. The locking block 32 is fixed to the bottom of the horizontal plate 31, and the top of the slider 2 has a first locking groove 9 that engages with the locking block 32. The column 33 is fixed to the top of the horizontal plate 31, and the dial indicator 4 is fixed to the top of the column 33. The locking block 32 and the first locking groove 9 facilitate easy assembly and disassembly.

[0037] The first positioning component 5 includes a first fixed shaft 51, a first rotating plate 52, a first bolt 53, and a pressure block 54. The first fixed shaft 51 is fixed to the top of the base 1. The first rotating plate 52 is rotatably connected to the upper part of the first fixed shaft 51. The first rotating plate has a first threaded hole 55. The bottom end of the first bolt 53 passes through the first threaded hole 55 and is fixed with the pressure block 54. When the first positioning component 5 needs to position the yarn feeder, the first rotating plate 52 is rotated forward so that the pressure block 54 is directly above the yarn feeder. Then, the first bolt 53 is tightened, pushing the pressure block 54 downward until the pressure block 54 presses down on the yarn feeder, preventing the yarn feeder from shifting during inspection and ensuring inspection accuracy.

[0038] The bottom of the pressure block 54 is fixed with a rubber pad 56. The rubber pad 56 is provided to prevent damage to the yarn feeder caused by direct squeezing between the pressure block 54 and the yarn feeder.

[0039] The second positioning component 6 includes a second fixed shaft 61, a second rotating plate 62, a lifting part 63, and a pressing part 64. The second fixed shaft 61 is fixed to the top of the base 1. The second rotating plate 62 is rotatably connected to the upper part of the second fixed shaft 61. The lifting part 63 is disposed on the second rotating plate 62, and the pressing part 64 is disposed at the lower part of the lifting part 63. Specifically, the lifting part 63 includes a retaining bead 631, a first spring 632, and a lifting plate 633. The rear side of the second rotating plate 62 has an insertion hole 65. The second rotating plate 62 on both sides of the insertion hole 65 has receiving grooves 66. One end of the first spring 632 is fixed with the retaining bead 631, and the other end of the first spring 632 is fixed in the receiving groove 66. The front and rear sides of the lifting plate 633 each have two vertically distributed second retaining grooves 637. The retaining bead 631 cooperates with the second retaining grooves 637, and the lifting plate 633 passes through the insertion hole 65. The pressure part 64 includes a second spring 641, a horizontal column 642, a vertical plate 643, a pressure strip 644, and a second bolt 645. The lower left side of the lifting plate 633 has a slot 634. One end of the horizontal column 642 is fixedly connected to the vertical plate 643, and the other end of the horizontal column 642 is inserted into the slot 634. One end of the second spring 641 is fixedly connected to the lifting plate 633, and the other end of the second spring 641 is fixedly connected to the vertical plate 643. The pressure strip 644 is fixed on the left side of the vertical plate 643. The lower part of the lifting plate 633 has a second threaded hole 635. The left end of the second bolt 645 passes through the second threaded hole 635 and contacts the right side wall of the vertical plate 643.

[0040] When the second positioning element 6 is needed to position the yarn feeder, the second rotating plate 62 is rotated forward so that the pressure part 64 is above the yarn feeder. Then, the lifting plate 633 is pushed downward, and the retaining bead 631 retracts into the receiving groove 66. At this time, the first spring 632 is compressed until the second retaining groove 637, located above, moves to the retaining bead 631. The first spring 632 extends and resets, pushing the retaining bead 631 into the second retaining groove 637, thus positioning the lifting plate 633 in the current position. The downward movement of the lifting plate 633 causes the pressure part 64 to move downward, which in turn causes the pressure strip 644 to extend into the slot of the yarn feeder. Then, the second bolt 645 is tightened, pushing the upright plate 643 to move to the right. At this time, the second spring 641 is stretched, and the rightward movement of the upright plate 643 drives the pressure strip 644 to move to the right, applying a rightward force to the yarn feeder, so that the ceramic head of the yarn feeder is tightly pressed against the left end wall of the slide groove 7, preventing the yarn feeder from shifting during inspection and ensuring inspection accuracy. The second spring 641 allows the upright plate 643 to move to the left and reset when the second bolt 645 is loosened. The cooperation between the crossbar 642 and the slot 634 ensures the stability of the upright plate 643 during movement.

[0041] The lifting plate 633 has a handle 636 fixed to its top. The handle 636 facilitates the up and down movement of the lifting plate 633.
