[0038] To make the objectives, technical solutions, and advantages of the present invention more apparent, various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in various embodiments of the present invention to facilitate a better understanding of the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the claims of this application can be implemented.

[0039] The first embodiment of the present invention relates to a parts clamping mechanism, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes: a base 1, a first positioning member 2, a second positioning member 3, a first positioning pin 4, a second positioning pin 5, a first fixing block 6, a second fixing block 7, a first clamping block 8 and a second clamping block 9.

[0040] Among them, Figure 1 、 Figure 2 and Figure 3 As shown, the base 1 includes: a bottom plate 11, a support plate 12 arranged on the bottom plate 11, the support plate 12 has a reference surface 121 perpendicular to the bottom plate 11, the reference surface 121 partially protrudes in a direction parallel to the bottom plate 11 to form a limiting protrusion 122, and the limiting protrusion 122 divides the reference surface 121 into an upper base surface 1211 and a lower base surface 1212.

[0041] Secondly, if Figure 1 、 Figure 2 and Figure 3 As shown, the first positioning member 2 includes: a first support arm 21 attached to the upper base surface 1211, and a first connecting arm 22 extending horizontally from one end of the first support arm 21 in a direction away from the reference surface 121. The second positioning member 3 includes: a second support arm 31 attached to the lower base surface 1212, and a second connecting arm 32 extending horizontally from one end of the first support arm 31 in a direction away from the reference surface 121. It should be noted that in this embodiment, as Figure 1 、 Figure 2 and Figure 3 As shown, the first support arm 21 can be fixedly connected to the upper base surface 1211 of the reference surface 121 by a locking member such as a bolt, while the second support arm 31 is fixedly connected to the lower base surface 1212 of the reference surface 121 .

[0042] In addition, if Figure 1 and Figure 3 As shown, the first locating pin 4 is arranged on the first connecting arm 22, and the second locating pin 5 is arranged on the second connecting arm 32. The first locating pin 4 and the second locating pin 5 are arranged on the same side and are respectively used to pass through the locating holes opened on the part 100.

[0043] In addition, if Figure 2 As shown, the first fixing block 6 is disposed between the first connecting arm 22 and the second connecting arm 32, and defines a first through slot 61 in a direction parallel to the reference plane 121. The second fixing block 7 is disposed opposite the first fixing block 6 in a direction perpendicular to the reference plane 121, and defines a second through slot 71 in a direction parallel to the reference plane 121.

[0044] Finally, if Figure 1 、 Figure 2 and Figure 3 As shown, the first clamping block 8 is partially embedded in the first through-slot 61 and is elastically hinged to the first fixing block 6. The second clamping block 9 is partially embedded in the second through-slot 71 and is elastically hinged to the second fixing block 7. The first clamping block 8 and the second clamping block 9 are used to clamp parts together, and the clamping directions of the first clamping block 8 and the second clamping block 9 are parallel to the base plate 11.

[0045] From the above, it is clear that the first locating pin 4 and the second locating pin 5 can achieve vertical positioning of the part, while the elastic hinge connection between the first clamping block 8 and the first fixing block 6, and the elastic hinge connection between the second clamping block 9 and the second fixing block 7, can achieve horizontal clamping and fixation of the part. It is clear that the clamping mechanism of this embodiment is not only simple in structure, but also can meet the clamping requirements of various irregularly shaped parts by positioning the part in both vertical and horizontal directions.

[0046] Specifically, in this embodiment, Figure 2 As shown, the first connecting arm 22 includes: a first inclined extension section 221 connected to the first support arm 21, and a horizontal extension section 222 connected to the first inclined extension section 221. The angle formed between the first inclined extension section 221 and the first support arm 21 is an acute angle, and the horizontal extension section 222 is perpendicular to the reference plane 121. The second connecting arm 32 includes: a second inclined extension section 321 connected to the second support arm 31, and a stopper 322 protruding from one end of the second inclined extension section 321 away from the second support arm 31 toward the horizontal extension section 222. At the same time, as Figure 1 and Figure 2 As shown, the first fixing block 6 is disposed between the first inclined extension section 221 and the second inclined extension section 321. Furthermore, the side of the horizontal extension section 222 facing the component 100 is the first positioning side 2221, while the side of the limiting protrusion 322 facing the component is the second positioning side 3221. The first positioning side 2221 and the second positioning side 3221 are coplanarly disposed in a direction perpendicular to the base plate 11. Furthermore, the first positioning pin 4 is disposed on the first positioning side 2221, while the second positioning pin 5 is disposed on the second positioning side 3221. Furthermore, the first positioning pin 4 and the second positioning pin 6 are also disposed opposite each other in a direction perpendicular to the base plate 11.

[0047] In addition, if Figure 2 As shown, as a preferred solution, in order to further improve the positioning performance of the part clamping mechanism on the part 100, a plurality of positioning grooves 2222 are further provided on the side of the horizontal extension section 222 relative to the part 100. The ribs on the back of the part 100 can be embedded through each positioning groove 2222, thereby further improving the clamping and positioning effect of the part 100.

[0048] In addition, it is worth mentioning that in order to achieve effective fixation of the second fixing block 7, as shown in FIG. Figure 2 As shown, the part clamping mechanism of this embodiment further includes: a support block 10 disposed on the base plate 11, and the support block 10 is arranged opposite the horizontal extension section 222 in a direction perpendicular to the base plate 11. Simultaneously, a second fixing block 7 is disposed on the support block 10 and located between the support block 10 and the horizontal extension section 222. Furthermore, in this embodiment, the support block 10 and the second fixing block 7 are integrally formed. Of course, it should be noted that in actual applications, the support block 10 and the second fixing block 7 can also be detachably connected.

[0049] In addition, in order to achieve the clamping and fixing of the part 100 by the first clamping block 8 and the second clamping block 9, as shown in FIG. Figure 3 As shown, the part clamping mechanism of this embodiment further includes: a first hinge axis 20, a first elastic element 30, a second hinge axis 40, and a second elastic element 50. The first hinge axis 20 articulates the first fixing block 6 and the first clamping block 8. The first elastic element 30 is disposed at the bottom of the first through-slot 61 and connected to the first clamping block 8 perpendicular to the reference plane 121. Correspondingly, the second hinge axis 40 articulates the second fixing block 7 and the second clamping block 9. The second elastic element 50 is disposed at the bottom of the second through-slot 71 and connected to the second clamping block 9 perpendicular to the reference plane 121. It is readily apparent that, in practice, the first clamping block 8 can rotate about the axis of the first hinge axis 20 under the rebound action of the first elastic element 30, while the second clamping block 9 can rotate about the axis of the second hinge axis 40 under the rebound action of the second elastic element 50, thereby achieving clamping and securing of the part 100. Specifically, in this embodiment, the first elastic element 30 and the second elastic element 40 are both elastic plungers, and the rotation of the first holding block 8 and the second clamping block 9 is achieved by the rebound force of the elastic plungers.

[0050] Furthermore, it should be noted that if Figure 1As shown, in this embodiment, the first clamping block 8 includes a first hinge portion 81 inserted into the first through-slot 61 and rotatably connected to the first hinge shaft 20, and a first hook portion 82 connected to the first hinge portion 81 and exposed outside the first through-slot 61. The second clamping block 9 includes a second hinge portion 91 inserted into the second through-slot 71 and rotatably connected to the second hinge shaft 40, and a second hook portion 92 connected to the second hinge portion 91 and exposed outside the second through-slot 71. In actual use, the first hook portion 82 of the first clamping block 8 and the second hook portion 92 of the second clamping block 9 can be used to clamp and secure the part 100.

[0051] It is not difficult to see from the above that this embodiment is a method example corresponding to the second embodiment, and this embodiment can be implemented in conjunction with the second embodiment. The relevant technical details mentioned in the second embodiment are still valid in this embodiment, and to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the second embodiment.

[0052] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
