[0047] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0048] Figure 1 This is a schematic diagram of a CNC machining equipment according to an embodiment of this application. See also: Figure 1 As shown, this application discloses a CNC machining equipment 10, which includes a machining device 100 and an automatic loading and unloading device 200. The automatic loading and unloading device 200 is used to transport the product 140 to be processed to the machining device 100.

[0049] This application also discloses an automatic loading and unloading device 200, which can be used in the CNC machining equipment 10 described above. Regarding the automatic loading and unloading device 200, this application provides the following design:

[0050] Figure 2 This is a schematic diagram of an automatic loading and unloading device according to an embodiment of this application. Figure 3 This is a partial schematic diagram of an automatic loading and unloading device according to an embodiment of this application, in conjunction with... Figures 2-3As shown, this application discloses an automatic loading and unloading device 200, which includes a loading plate 210, an annular track 220, an annular conveyor chain 230, multiple fixed bases 300, and multiple product fixing clamps 400. The annular track 220 is disposed on the loading plate 210, and the annular conveyor chain 230 is also disposed on the loading plate 210, with the annular track 220 surrounding the annular conveyor chain 230. The bottom of the fixed base 300 is slidably connected to the annular track 220, and the fixed base 300 is also connected to the annular conveyor chain 230. The annular conveyor chain 230 is used to drive the fixed base 300 to slide on the annular track 220. The product fixing clamps 400 are connected to the fixed bases 300 and are used to fix the product 140 to be processed.

[0051] The automatic loading and unloading device 200 also includes a transfer unit 600, which is used to transfer the product fixing clamp 400, which holds the product 140 to be processed, to the processing device 100 for processing.

[0052] Compared to the existing solution of directly gripping parts in the processing device 100 using grippers, the solution of this application uses product clamping clamps 400 to fix the product to be processed, and sets multiple fixing bases 300 on the circular track 220 to hold multiple product clamping clamps 400. The product clamping clamps 400 with the product to be processed 140 fixed can be directly transported to the processing device 100 for processing through the transfer unit 600. This means that when processing a product 140, it is not necessary to stop the CNC processing equipment 100 for material change and fixing, thereby improving processing efficiency.

[0053] Moreover, there is no need to stop the machine when fixing the product to be processed in the product clamp 400, selecting the NC program, setting the tool compensation, etc.

[0054] Furthermore, the fixed base 300 and the product fixing clamp 400 are separate. Therefore, when fixing the product to be processed 140 onto the product fixing clamp 400, it is not necessary to operate inside the automatic loading and unloading device 200. The product fixing clamp 400 can be taken out, the product to be processed 140 can be fixed on the product fixing clamp 400 first, and then placed on the fixed base 300 to complete the process, thereby improving the efficiency of fixing the product to be processed 140.

[0055] Furthermore, the transfer unit 600 directly transfers the product fixing clamp 400 that holds the product to be processed 140. Since the product fixing clamp 400 has the same structure, there is no need to adjust the structure of the transfer unit 600 when transferring different products, thus making it compatible with more products 140 of different shapes.

[0056] Figure 4 This is a schematic diagram of a product fixing clamp according to an embodiment of this application. Figure 5 This is a schematic diagram of another perspective of a product fixing clamp according to an embodiment of this application. See also... Figures 4-5 As shown, the product fixing clamp 400 includes a fixing clamp base 410, a threaded screw 420, a left pressure plate 431, and a right pressure plate 432. The fixing clamp base 410 has a groove on its top, and a pressure plate slide rail is provided on the inner wall of the groove. The left pressure plate 431 and the right pressure plate 432 are slidably connected to the pressure plate slide rail. The threaded screw 420 is disposed in the groove, and both ends of the threaded screw 420 are threadedly connected to the left pressure plate 431 and the right pressure plate 432, respectively. The product fixing clamp 400 also includes a left caliper 441 and a right caliper 442. The left caliper 441 is detachably connected to the left pressure plate 431, and the right caliper 442 is detachably connected to the right pressure plate 432.

[0057] By rotating the threaded screw 420 forward or backward, the left pressure plate 431 and the right pressure plate 432 can be moved away from or closer to each other, thereby moving the left caliper 441 and the right caliper 442 away from or closer to each other. The product to be processed 140 is placed between the left caliper 441 and the right caliper 442, and then the threaded screw 420 is rotated to move the left caliper 441 and the right caliper 442 closer to each other, thereby clamping the product to be processed 140, thus completing the fixation of the product to be processed 140 to the product fixing clamp 400.

[0058] Furthermore, the left caliper 441 is detachably connected to the left pressure plate 431, and the right caliper 442 is detachably connected to the right pressure plate 432. In this way, when processing other products 140 of different shapes, the corresponding adaptation can be completed by replacing the left caliper 441 and the right caliper 442, thereby reducing the cost of the automatic loading and unloading device 200.

[0059] Figure 6 This is a schematic diagram of a pneumatic chuck according to an embodiment of this application, in conjunction with... Figure 5 and Figure 6 As shown, the bottom of the product fixing clamp 400 is provided with four sets of locking holes 460, each set of locking holes 460 including a first locking hole 461 and a second locking hole 462; specifically, the four sets of locking holes 460 are provided at the bottom of the fixing clamp base 410.

[0060] The processing device 100 also includes a pneumatic chuck 110. The top of the pneumatic chuck 110 is provided with four jaws 120. Each jaw 120 is provided with two protrusions 121. The two protrusions 121 are respectively used to engage with the first chuck hole 461 and the second chuck hole 462. The pneumatic chuck 110 is also provided with a chuck positioning groove 130. The inner wall of the chuck positioning groove 130 is used to abut against the positioning shaft 412.

[0061] By setting up a pneumatic chuck 110, and providing four sets of chuck holes 460 in the fixed clamp seat 410 and four chuck claws 120 on the top of the pneumatic chuck 110, the transfer unit 600 directly transfers the product fixing clamp 400, which is fixed with the product to be processed 140, to the pneumatic chuck 110, and then the processing device 100 processes the product to be processed 140.

[0062] Figure 7 This is a schematic diagram of a fixing clamp seat according to an embodiment of this application, combined with... Figure 5 and Figure 7 As shown, the bottom of the fixing clamp 410 is provided with four positioning nuts 411 and a positioning shaft 412, and the four positioning nuts 411 are located around the positioning shaft 412.

[0063] The top of the fixed base 300 is provided with a first positioning groove 311, a second positioning groove 312 and a positioning hole 313. The positioning hole 313 is located between the first positioning groove 311 and the second positioning groove 312. The inner wall of the first positioning groove 311 is used to abut against two positioning nuts 411, the inner wall of the second positioning groove 312 is used to abut against two other positioning nuts 411, and the inner wall of the positioning hole 313 is used to abut against the positioning shaft 412.

[0064] A first positioning groove 311, a second positioning groove 312, and a positioning hole 313 are provided on the top of the fixed base 300. Then, four positioning nuts 411 and a positioning shaft 412 are provided at the bottom of the fixed clamp 410. The inner wall of the first positioning groove 311 abuts against two of the positioning nuts 411, the inner wall of the second positioning groove 312 abuts against the other two positioning nuts 411, and the inner wall of the positioning hole 313 abuts against the positioning shaft 412. Thus, the fixed clamp 410 can be conveniently and quickly inserted and installed onto the fixed base 300.

[0065] Furthermore, the annular track 220 is a rounded rectangle, the number of fixed bases 300 includes 12, the number of product fixing clamps 400 is the same as the number of fixed bases 300, and every three fixed bases 300 are slidably connected to one side of the annular track 220.

[0066] After installing the three fixed clamps 410 with the products to be processed 140 onto the fixed base 300, the other three empty fixed bases 300 can be rotated to the loading position by rotating the annular conveyor chain 230 by 1 / 4, making it convenient for the staff to load the materials. In this way, 12 fixed clamps 410 with the products to be processed 140 onto the fixed base 300 can be installed at the same time, thereby avoiding the need for the staff to install them frequently and improving the processing efficiency.

[0067] The outer and inner walls of the annular track 220 are both recessed; the bottom of the fixed base 300 is also provided with an outer track roller 331 and an inner track roller 332, the outer track roller 331 abuts against the outer wall of the annular track 220, and the inner track roller 332 abuts against the inner wall of the annular track 220.

[0068] By setting an outer track roller 331 and an inner track roller 332 at the bottom of the fixed base 300, the annular track 220 is clamped from the inside and outside, thereby ensuring the stable operation of the fixed base 300 on the annular track 220.

[0069] Figure 8 This is a schematic diagram of a positioning unit according to an embodiment of this application. See also: Figure 8 As shown, the fixed base 300 is provided with a positioning slot 320 near the edge of the loading plate 210.

[0070] The automatic loading and unloading device 200 also includes a positioning unit 500, which is connected to one side of the loading carrier plate 210. The positioning unit 500 includes a positioning clip 510, which is used to engage with the positioning slot 320.

[0071] By engaging the positioning clip 510 with the positioning slot 320, the fixed base 300 can be positioned, thereby preventing the transfer unit 600 from failing to accurately insert the product fixing clamp 400.

[0072] Furthermore, the number of positioning clips 510 includes three, which are respectively defined as the first positioning clip 511, the second positioning clip 512, and the third positioning clip 513. The positioning unit 500 also includes a first fixing plate 521, a rotating shaft 530, a second fixing plate 522, a rotating plate 540, and a reciprocating motor 550. The first fixing plate 521 and the second fixing plate 522 are respectively connected to the loading plate 210. The reciprocating motor 550 is connected to the loading plate 210. The output end of the reciprocating motor 550 is connected to the end of the rotating plate 540. One end of the rotating shaft 530 is connected to the first fixing plate 521, and the other end passes through the second fixing plate 522 and is connected to the rotating plate 540.

[0073] The first positioning clip 511, the second positioning clip 512 and the third positioning clip 513 are all connected to the rotating shaft 530, and the first positioning clip 511, the second positioning clip 512 and the third positioning clip 513 correspond to the positioning slots 320 of the three fixed bases 300 respectively. The reciprocating motor 550 is used to drive the rotating plate 540 to rotate.

[0074] The reciprocating motor 550 drives the rotating plate 540 to rotate, thereby causing the first positioning clip 511, the second positioning clip 512 and the third positioning clip 513 to rotate, so that the first positioning clip 511, the second positioning clip 512 and the third positioning clip 513 are respectively locked in the positioning slots 320 of the three fixed bases 300.

[0075] The first positioning clip 511, the second positioning clip 512, and the third positioning clip 513 can be synchronously engaged and aligned with the positioning slots 320 of the three fixed bases 300 by only driving them once through the reciprocating motor 550, thereby further improving efficiency.

[0076] Figure 9 This is a schematic diagram of a transfer unit according to an embodiment of this application, in conjunction with... Figure 5 and Figure 9 As shown, the product fixing clamp 400 also includes a first hook protrusion 451 and a second hook protrusion 452, and the first hook protrusion 451 and the second hook protrusion 452 are respectively disposed on both sides of the fixing clamp base 410.

[0077] The transfer unit 600 includes a translation module 610, a motion module 620, a connecting rod 630, and a bidirectional insert plate 640. The motion module 620 is connected to the translation module 610, and one end of the connecting rod 630 is connected to the motion module 620, while the other end is connected to the bidirectional insert plate 640. The translation module 610 is used to drive the motion module 620 to move, and the motion module 620 is used to drive the connecting rod 630 to rotate and move up and down, thereby driving the bidirectional insert plate 640 to move up and down and rotate.

[0078] The bidirectional insert plate 640 includes an insert plate body 641, a first left support rod 651, a second left support rod 652, a first right support rod 661, and a second right support rod 662. The first left support rod 651 and the second left support rod 652 are located on opposite sides of the same side of the insert plate body 641, and the first right support rod 661 and the second right support rod 662 are located on opposite sides of the same side of the insert plate body 641.

[0079] The first left support rod 651 is provided with a hanging ear groove 670 on the side near the second left support rod 652, and the second left support rod 652 is also provided with a hanging ear groove 670 on the side near the first left support rod 651. The hanging ear grooves 670 on the first left support rod 651 and the second left support rod 652 are used to support the first hanging ear protrusion 451 and the second hanging ear protrusion 452 on both sides of the fixing clamp seat 410.

[0080] The first right support rod 661 is provided with a hanging ear groove 670 on the side near the second right support rod 662, and the second right support rod 662 is also provided with a hanging ear groove 670 on the side near the first right support rod 661.
