DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0028] like Figure 1 As shown, the utility model provides a technical solution: a deformation inspection tool for automobile instrument trim strips, comprising a workbench 10, a lower detection mold 11 is placed at the middle end of the upper end surface of the workbench 10, cylinders 12 are fixedly installed on both sides of the lower detection mold 11, top plates 13 are fixedly installed on the piston ends of the two cylinders 12, connecting plates 14 are symmetrically fixedly connected to the lower end surfaces of the top plates 13 on both sides, two cross plates 15 are fixedly connected between the two connecting plates 14, and upper detection molds 16 are fixedly connected to the bottom ends of the two connecting plates 14, and the upper detection mold 16 is provided with a plurality of detection components for detecting the deformation of automobile instrument trim strips. During specific use, the cylinder 12 is used to drive the upper detection mold 16 to move up and down, so as to facilitate the placement of the automobile instrument trim strips, the automobile instrument trim strips are inspected by the upper detection mold 16 and the lower detection mold 11, the automobile instrument trim strips are deformed by the detection components, and the automobile instrument trim strips are determined to be qualified by the detection results given by the detection components. The detection method is quick and convenient.

[0029] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, a lower shaping cavity 111 is provided on the upper end surface of the lower detection mold 11, and an upper shaping cavity 161 is provided on the lower end surface of the upper detection mold 16. The upper shaping cavity 161 and the lower shaping cavity 111 are combined to form a cavity for accommodating automobile instrument trims, and the upper shaping cavity 161 and the lower shaping cavity 111 are detection spaces for detecting automobile instrument trims.

[0030] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the detection component includes through holes 20 opened on both sides of the two horizontal plates 15 and four fixed holes 21 opened on the upper detection mold 16, and positioning rods 22 are vertically inserted in the fixed holes 21 and the through holes 20. The top ends of the four positioning rods 22 are fixedly connected to top blocks 23. Four control switches 24 are fixedly installed on the lower end surface of the top plate 13. The four control switches 24 are correspondingly arranged directly above the four top blocks 23. Four warning lights 25 are fixedly installed on the upper end surface of the top plate 13. The four warning lights 25 are electrically connected to the control switches 24, and the four control switches 24 are electrically connected to an external power supply. In the specific use process, when the upper detection mold When the tool 16 moves downward, the upper detection mold 16 and the lower detection mold 11 are closed, and if the automobile instrument trim is deformed at this time, the positioning rod 22 will move upward due to the bulging part of the automobile instrument trim, and the positioning rod 22 moves upward in the fixed hole 21 and the through hole 20, so that the top block 23 set on the top of the positioning rod 22 presses the control switch 24 upward, and when the control switch 24 is squeezed, it starts to be energized, so that the external power supply supplies power to the warning light 25, so as to remind the staff that the automobile instrument trim is deformed. It should be noted that when the control switch 24 is not squeezed, the external power supply does not supply power to the warning light 25.

[0031] Among them, the outer diameter of the positioning rod 22 is smaller than the inner diameter of the fixed hole 21 and the through hole 20, so that the positioning rod 22 can shuttle up and down in the fixed hole 21 and the through hole 20. The outer wall of the positioning rod 22 contacts the inner wall of the fixed hole 21 and the through hole 20, so as to limit the positioning rod 22 and prevent the positioning rod 22 from deviating left and right, so that the top block 23 at the top of the positioning rod 22 can accurately contact the control switch 24.

[0032] As an implementation method in this embodiment, Figure 2 As shown, an extrusion disk 26 is fixedly sleeved on the outer wall at the bottom of the four positioning rods 22, and a return spring 27 is arranged between the extrusion disk 26 and the cross plate 15. The return spring 27 is wound around the outer wall of the positioning rod 22. The positioning rod 22 will always fall downward due to gravity. However, in actual operation, in order to avoid friction obstruction when the positioning rod 22 shuttles between the fixed hole 21 and the through hole 20, the elastic force of the return spring 27 is used to make the positioning rod 22 fall downward quickly when it does not contact the raised point of the automobile instrument trim, so that the positioning rod 22 quickly returns to its position, and when the return spring 27 is compressed, the extrusion disk 26 is driven by the positioning rod 22 to squeeze the return spring 27, the bottom end of the return spring 27 is fixedly connected to the upper end surface of the extrusion disk 26, and the top end of the return spring 27 is fixedly connected to the lower end surface of the cross plate 15, so as to avoid the return spring 27 from deflecting during compression or extension.

[0033] As an implementation method in this embodiment, Figure 2As shown, the bottom ends of the four positioning rods 22 extend vertically downward to the inside of the upper shaping cavity 161 and the ends are fixedly connected with a resistance block 28. The resistance block 28 can expand the contact range of the positioning rods 22, thereby expanding the detection range.

[0034] Working principle: When in use, when the upper detection mold 16 moves downward, the upper detection mold 16 and the lower detection mold 11 are closed, and if the automobile instrument trim is deformed at this time, the positioning rod 22 will move upward due to the convex part of the deformation of the automobile instrument trim, and the positioning rod 22 moves upward in the fixed hole 21 and the through hole 20, so that the top block 23 set at the top of the positioning rod 22 squeezes the control switch 24 upward, and when the control switch 24 is squeezed, it starts to power on, so that the external power supply supplies power to the warning light 25, so as to remind the staff that the automobile instrument trim is deformed, thereby completing the operation of detecting deformation.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
