[0037] The fixing mechanism 4 includes a pressing rod assembly 41 correspondingly rotatably mounted on the mounting seat 2, a limiting plate assembly 42 slidably arranged between the two groups of the mounting seats 2 and driving the two groups of the pressing rod assemblies 41 to be offset and pressed downward, and a power assembly 43 driving the limiting plate assembly 42 to move.

[0038] It should be noted that the external graduated rotating platform is preferably graduated by 180°, and cooperates with the two groups of pressing rod assemblies 41 to loosen and clamp the parts in the two groups of positioning parts 313, so as to realize the non-stop production and processing of the parts, thereby improving the production efficiency.

[0039] It should be further explained that the indexing rotary platform is a prior art and will not be described in detail here.

[0040] It is important to explain that the offset pressing means that one group of the pressing rod assemblies 41 is pressed down while another group of the pressing rod assemblies 41 is lifted up, and the two groups are performed simultaneously and in opposite movements.

[0041] Further, such as Figure 4 As shown, the mounting seat 2 is provided with a chip removal channel 21 which is in communication with the positioning portion 313 .

[0042] It should be noted that the chip removal channel 21 can enable the waste chips generated by machining to be quickly discharged, which is beneficial to the collection of the waste chips.

[0043] Further, such as Figure 5 As shown, the supporting seat 311 includes a supporting seat body 3111, a guide section 3112 arranged above one side of the supporting seat body 3111 and inclined, a positioning section 3113 arranged below the guiding section 3112 and transitionally connected to the guiding section 3112, and a supporting section 3114 arranged below the positioning section 3113.

[0044] It should be noted that if Figure 4 and Figure 5 As shown, several groups of the guiding segments 3112 form the guiding portion 312 , and several groups of the positioning segments 3113 and the supporting segments 3114 form the positioning portion 313 .

[0045] It is also necessary to explain that the parts are placed on the supporting section 3114, and a plurality of groups of the supporting seats 311 are arranged at intervals so that the parts can be placed more stably and the flatness is ensured.

[0046] Further, such as Figure 1 and Figure 3 As shown, the pressing rod assembly 41 includes a rotating seat 411 installed on one side of the mounting seat 2, a rotating rod 412 hingedly installed on the rotating seat 411, a contact portion 413 arranged at the front end of the rotating rod 412, a spring a414 arranged on the other side of the hinge point of the rotating rod 412 relative to the contact portion 413 and connected to the clamp base plate 1, and an interference portion 415 arranged at the end of the rotating rod 412.

[0047] It should be noted that the spring a414 can enable the rotating rod 412 to be lifted quickly.

[0048] It is also necessary to explain that the contact portion 413 presses the middle position of the part, so that the clamp is more suitable for tapping the metal frame components of the mobile phone.

[0051] It should be noted that when the abutment portion 415 at the end of one rotating rod 412 abuts against the clamping section 4231 in the corresponding limiting portion 423, the abutment portion 415 at the end of the other rotating rod 412 abuts against the fixing section 4232 in the corresponding limiting portion 423, thereby realizing the loosening and clamping of the parts in the two groups of the positioning portions 313.

[0052] Furthermore, the power assembly 43 includes a cylinder mounting seat 431 disposed on the fixture base plate 1 and a cylinder 432 mounted on the cylinder mounting seat 431 and having a power shaft connected to the limiting plate body 422 .

[0053] It should be noted that the brand of the cylinder 432 is Qilike, and the model is DN32×50.

[0054] Working process:

[0055] The part to be processed is placed into the positioning part 313 through the guide part 312, and then the cylinder 432 drives the limit plate body 422 to move, and the resistance part 415 at the end of the rotating rod 412 corresponding to the positioning part 313 moves from the clamping section 4231 to the fixed section 4232, and then the contact part 413 presses and fixes the part. At the same time, the resistance part 415 at the end of the rotating rod 412 corresponding to another group of the positioning parts 313 moves from the fixed section 4232 to the clamping section 4231, and the contact part 413 leaves the positioning part 313. The released positioning part 313 is loaded and unloaded, and the clamped positioning part 313 is processed.
