[0024] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments. Example 1

[0025] See also Figure 1 and Figure 2As shown, this embodiment provides a quick-change device for positioning parts. The quick-change device includes: a base 1, an unlocking pin 3, a latch pin 4, a spring 5 and a cylindrical pin 6; the base 1 is installed on the tray, and the base 1 is used to insert the positioning part 2; the unlocking pin 3 is arranged parallel to one side of the positioning part 2; the latch pin 4 passes through the unlocking pin 3 and is movably connected to the positioning part 2; the cylindrical pin 6 passes through the unlocking pin 3 and the latch pin 4 in a vertical state; and the spring 5 is installed below the unlocking pin 3.

[0026] In this embodiment, the unlocking pin 3 is provided with two symmetrical through holes 311 and two symmetrical slide grooves 312; the through holes 311 are opened along the installation direction of the unlocking pin 3; and the opening position of the slide groove 312 is in the vertical direction of the through hole 311. Specifically, the unlocking pin 3 is designed with two symmetrical through holes 311 and two symmetrical slide grooves 312, such as Figure 3 and 4 The through hole 311 is opened along the installation direction of the unlocking pin 3, that is, parallel to the positioning part 2; the slide groove 312 is opened in the vertical direction of the through hole 311, and the opening direction of the slide groove 312 is inclined to the lower right, as shown in FIG. Figure 3 shown.

[0027] In this embodiment, one end of the latch 4 passes through the through hole 311 and is movably connected to the positioning part 2, and the other end contacts the two slide grooves 312 through the cylindrical pin 6, and the cylindrical pin 6 vertically passes through the latch 4. Specifically, the latch 4 passes through the through hole 311 horizontally, and the latch 4 and the through hole 311 are in a vertical state; one end of the latch 4 passes through the through hole 311 and is movably connected to the positioning part 2, and the latch 4 is inserted into the concave groove 8 of the positioning part 2. The other end of the latch 4 contacts the two symmetrical slide grooves 312 and is located in the middle of the two slide grooves 312; at the same time, the cylindrical pin 6 passes through the latch 4 and the slide groove 312 in a vertical state and is placed at the bottom position of the slide groove 312. This is the initial state, and the spring 5 is in a state of no force.

[0028] In this embodiment, the cylindrical pin 6 passes through the slide groove 312 and moves along the slide groove 312. The base 1 is fixed to the tray by bolts 7. Specifically, one end of the cylindrical pin 6 is fixed to the base 1, and the other end passes through the slide groove 312 and is placed at the bottom of the slide groove 312. The base 1 is fixed to the tray by bolts. When the unlocking pin 3 is pressed, the spring 5 is compressed, the unlocking pin 3 moves downward, and the cylindrical pin 6 moves upward from the bottom of the slide groove 312 along the trajectory of the slide groove 312, while driving the latch 4 to move outward, so that one end of the latch 4 inserted into the concave groove 8 of the positioning part 2 is separated from the concave groove 8, so that the previously installed positioning part 2 can be removed.

[0029] In this embodiment, the surface of the positioning part 2 is provided with a concave groove 8, and one end of the latch 4 passes through the through hole 311 and is inserted into the concave groove 8. Specifically, the surface of the positioning part 2 is provided with a concave groove 8, and the concave groove 8 is used to insert the latch 4; it should be noted that the quick-change device can be used for the same type of positioning parts 2 with a concave design on the surface, but the concave design is not necessarily the design of the concave groove 8 in this embodiment, as long as it can be inserted with the latch 4, and it can also be designed as a small hole shape, which is not specifically limited here.

[0030] The present embodiment provides a quick-change device for positioning parts. The quick-change device is designed with an unlocking pin, a latch pin and a cylindrical pin. The latch pin is inserted through the unlocking pin and the concave groove on the positioning part, and then the cylindrical pin is inserted through the unlocking pin and the latch pin respectively and embedded in the slide groove of the unlocking pin, and then a spring is installed at the bottom of the unlocking pin. When the positioning part needs to be replaced, only the button of the unlocking pin needs to be pressed, and the spring will be compressed, driving the cylindrical pin and the latch pin to move along the slide groove, so that the latch pin leaves the concave groove of the positioning part. The quick-change device solves the problem of manual disassembly and replacement when replacing the same type of positioning parts, reduces the consumption of manpower and material resources, and improves work efficiency.

[0031] The working principle of the utility model is as follows: the quick-change device equipped with the positioning part 2 is installed on the pallet, and the base 1 is fixed on the pallet with bolts 7. After the installation is completed, the spring 5 is in an unstressed state, one end of the latch 4 is located at the bottom position of the slide groove 312, and the other end is inserted into the concave groove 8 of the positioning part 2 to fix the positioning part 2; when a new positioning part 2 needs to be replaced, the unlocking pin 3 is pressed downward, the spring 5 is compressed, and the latch 4 moves outward along the trajectory of the slide groove 312 with the connected cylindrical pin 6, thereby separating from the concave groove 8 of the original positioning part 2. At this time, the original positioning part 2 can be pulled out and replaced with a new positioning part 2, thereby realizing the rapid replacement of the positioning part 2, reducing the consumption of manpower and material resources, and improving work efficiency.

[0032] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
