[0044] Reference below Figures 1 to 9 The clamp, the fixture base and the automatic clamping machine according to the embodiment of the present invention are described.

[0045] like Figures 1 to 7 As shown, the clamp according to the embodiment of the first aspect of the present invention includes: an upper plate 100, a fixing member 200 and a lower plate 300, the upper plate 100 is used to carry the product 900 and is provided with a plurality of through holes 110, the aperture of the through holes 110 is smaller than the outer diameter of the product 900; the fixing member 200 includes a fixing member 200 body and a first flange 210 and a second flange 220 respectively provided at both ends of the fixing member 200 body, the outer diameter of the second flange 220 is smaller than the inner flange aperture of the product 900 and the aperture of the through holes 110, the outer diameter of the first flange 210 is larger than the inner flange aperture of the product 900, so that the second flange 220 The edge 220 can pass through the inner flange and the through hole 110, so that the first flange 210 can abut against the upper end surface of the inner flange; the lower plate 300 is arranged below the upper plate 100, and the lower plate 300 is provided with a locking groove 320 and a through hole 310 for the second flange 220 to pass through. The groove direction of the locking groove 320 is perpendicular to the depth direction of the through hole 310, and the locking groove 320 is connected with the through hole 310 so that the second flange 220 can slide from the through hole 310 to the locking groove 320. A convex edge is provided on the top of the locking groove 320, which is used to limit the movement of the second flange 220 along the depth direction of the locking groove 320.

[0046] It is understood that after the product 900 is placed on the upper plate 100 corresponding to the through hole 110, and the second flange 220 of the fixing member 200 is passed through the inner hole of the product 900, the through hole 110, and the through hole 310, the first flange 210 of the fixing member 200 abuts against the upper end surface of the inner flange of the product 900, so that the product 900 is clamped between the upper plate 100 and the fixing member 200. At this time, the upper plate 100 is pushed to slide the second flange 220 from the through hole 310 to the locking groove 320. The ridge at the top of the locking groove 320 can limit the movement of the second flange 220 along the depth direction of the locking groove 320, thereby locking the fixing member 200 and then the product 900. This fixture achieves the locking of the hollow product 900, and when there are multiple through holes 110 and fixing members 200, this fixture can lock multiple products 900 at the same time to facilitate subsequent grinding and other processing.

[0047] It is understood that the upper plate 100 and the lower plate 300 are provided with a guide column 120 and a strip hole 330 on their opposite surfaces, respectively. The guide column 120 is passed through the strip hole 330, and the strip hole 330 is parallel to the locking groove 320. For example, Figure 7 As shown, in this embodiment, a guide column 120 can be set on the end surface of the upper plate 100 facing the lower plate 300, and a strip hole 330 can be set on the lower plate 300, or a guide column 120 can be set on the end surface of the lower plate 300 facing the upper plate 100, and a strip hole 330 can be set on the upper plate 100; the strip hole 330 and the locking groove 320 are parallel, so pushing the upper plate 100 or the lower plate 300 can make the guide column 120 slide along the strip hole 330, so that the second flange 220 slides from the through hole 310 to the locking groove 320, thereby achieving locking of the product 900 and the fixing part 200 along the depth direction of the locking groove 320.

[0048] It is understood that the clamp further includes a locking pin, and the upper plate 100 and the lower plate 300 are provided with corresponding locking holes 410, so that when the locking groove 320 is positioned at the second flange 220, the locking holes 410 of the upper plate 100 and the lower plate 300 can be aligned for insertion of the locking pin, so that the fixing member 200 and the product 900 are locked between the upper plate 100 and the lower plate 300. For example, Figure 7 As shown, in this embodiment, when the second flange 220 is restrained by the convex edge in the locking groove 320, the locking holes 410 of the upper plate 100 and the lower plate 300 are aligned, and the locking pin can be inserted into the locking holes 410 of the upper plate 100 and the lower plate 300, thereby achieving horizontal locking of the fixing member 200 and the product 900. The locking holes 410 and the locking pins can be provided in a corresponding set or multiple sets.

[0049] It is understood that the upper plate 100 is provided with a support seat 130 for supporting the product 900, and the top of the support seat 130 protrudes from the upper end surface of the upper plate 100. Figures 3 to 5As shown, in this embodiment, by providing a support base 130 protruding from the upper plate 100 , the product 900 can be lifted up on the upper plate 100 , so that the product 900 with a smaller height can be removed from the upper plate 100 .

[0050] Specifically, the support seat 130 in the embodiment of the present invention is penetrated through the through hole 110 along the inner wall of the through hole 110, and the top of the support seat 130 protrudes from the upper end surface of the upper plate 100, and the bottom of the support seat 130 extends horizontally away from the through hole 110, so that the support seat 130 can be fixed to the upper plate 100 by fasteners.

[0051] like Figure 8 As shown, the fixture seat according to the second embodiment of the present invention includes the fixture of the first embodiment mentioned above, and also includes a base 500 for placing the fixture. The base 500 is provided with a guide pin 510 and a first driving member. The first driving member is used to drive the guide pin 510 to be ejected or retracted. When the guide pin 510 is ejected, it can pass through the through hole 310 and the through hole 110 in sequence. The outer diameter of the guide pin 510 exposed in the through hole 110 is smaller than the inner flange hole diameter of the product 900, so that the product 900 can slide along the guide pin 510 onto the upper plate 100.

[0052] It is understood that when the upper plate 100 and the lower plate 300 are placed on the base 500, the guide pin 510 is ejected by the first driving member, passing through the perforation 310 and the through hole 110 and then exposed on the upper plate 100. The outer diameter of the guide pin 510 exposed through the through hole 110 is smaller than the inner diameter of the product 900, thereby facilitating the placement of the product 900. The product 900 can slide along the guide pin 510 and align with the through hole 110 onto the upper plate 100. When the product 900 needs to be locked, the first driving member drives the guide pin 510 to retract, allowing the fixing member 200 to pass through the through hole 110 and be placed on the inner flange of the product 900. The guide pin 510 can make it easier to align the product 900 with the through hole 110 and place it on the upper plate 100.

[0053] It is understandable that the outer diameter of the guide pin 510 decreases gradually from bottom to top. Figure 8 As shown, in this embodiment, the outer diameter of the guide pin 510 exposed in the through hole 110 is smaller than the inner diameter of the product 900, and the outer diameter of the top of the guide pin 510 is smaller than the outer diameter below the guide pin 510, thereby making it easier for the product 900 to align with the top of the guide pin 510.

[0054] It is understood that the upper plate 100 and the lower plate 300 are provided with corresponding positioning holes, and the base 500 is provided with positioning posts 520. When the upper plate 100 and the lower plate 300 are placed on the fixture seat, the positioning posts 520 can pass through the positioning holes aligned with the upper plate 100 and the lower plate 300. For example, Figure 8As shown, in this embodiment, when the upper plate 100 and the lower plate 300 are placed on the base 500, the positioning holes of the upper plate 100 and the lower plate 300 need to be aligned through the positioning posts 520 on the base 500 to achieve positioning of the upper plate 100 and the lower plate 300. The positioning holes and the positioning posts 520 can be provided in one set or in multiple sets.

[0055] like Figure 9 As shown, the automatic clamping machine according to the third embodiment of the present invention includes the fixture base of the second embodiment of the present invention, and also includes a robot 600, and the lower end of the robot 600 is provided with a plurality of pneumatic clamping fingers 610 for picking up and placing the product 900 on the upper plate 100.

[0056] It can be understood that when loading, the product 900 is picked up by the pneumatic gripper 610 at the lower end of the robot 600 and released to the upper plate 100 along the guide needle 510. When unloading, the product 900 is removed from the upper plate 100 by the pneumatic fingers. The whole process is highly automated, which greatly improves the efficiency of loading and unloading.

[0057] It is understood that the automatic clamping machine includes an adsorption device 700 for sucking or releasing the fixing member 200 to the upper plate 100. For example, Figure 9 As shown, in this embodiment, when it is necessary to fix the product 900, the fixing part 200 is placed on the inner flange of the product 900 through the adsorption device 700, and then the upper plate 100 or the lower plate 300 is pushed to make the second flange 220 be stuck in the convex edge, thereby locking the fixing part 200 and the product 900; when it is necessary to remove the product 900, the second flange 220 is first slid out of the locking groove 320, and then the several fixing parts 200 are removed together through the adsorption device 700, so that the pneumatic clamping fingers 610 can remove the product 900.

[0058] It should be understood that the upper plate 100 and the lower plate 300 are also provided with corresponding alignment holes, and the adsorption device 700 is provided with a positioning cone adapted to the alignment hole. When the fixture seat is located below the adsorption device 700, the positioning cone corresponds to the alignment hole, so that the adsorption device 700 can align with the upper plate 100 to remove several fixing parts 200.

[0059] It is understood that the automatic clamping machine includes a guide rail 800 for the fixture seat to slide and a second driving member for driving the fixture seat to slide, and the guide rail 800 extends from the manipulator 600 to the adsorption device 700. For example, Figure 9As shown, in this embodiment, the guide rail 800 extends to the manipulator 600 and the adsorption device 700, so that the jig seat is first discharged by the manipulator 600, and then slides to the adsorption device 700, and the adsorption device 700 places the fixing part 200 on the jig seat; after the product 900 is processed and the material is taken out, the fixing part 200 is first removed by the adsorption device 700, and the jig seat slides to the manipulator 600, and then the manipulator 600 removes the product 900.

[0060] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
