[0029] As shown in Figure 6 and Figure 7As shown, the special equipment for milling multiple pieces of water-cut products at one time mainly includes a machine body 29, a robot 30 and a turntable 31. The robot 30 is arranged on each of the left and right sides of the machine body 29, and the turntable 31 is arranged in the middle of the machine body 29. An inclined turntable support 32 is arranged on the turntable 31, and a clamping fixture is installed on the inclined turntable support 32. The robot 30 and the turntable 31 are installed on the machine body 29 with a certain distance. At the same time, the AB surface on the turntable 31 is inclined at a certain angle, and a clamping fixture that can hold multiple products is placed, so that the robot 30 can mill the two ends of multiple products in sequence and at the same time, thereby achieving the requirement of efficient production. When the mechanism is working, A plurality of water-cut products are fixed to the A-side fixture, and the turntable 31 rotates to turn the A-side to the processing position. Through the pre-programmed path program, the robots 30 on the left and right sides simultaneously process the two ends of the product on the A-side in sequence without gaps. When the processing is completed, the operator also places the parts on the B-side (already in the operating position) at the same time, and then the B-side enters the processing position for processing. At the same time, the A-side is turned to the operating position for picking and placing parts. This reciprocating working cycle is repeated. The first identification element 33 and the second identification element 34 are respectively arranged on the fuselage 29, wherein the first identification element 33 is mainly used to identify the A-side, and the second identification element 34 is mainly used to identify the B-side, so that the milling process can be performed after the product is detected.

[0030] like Figure 1 and Figure 2 As shown, the clamping fixture is mainly used to realize the clamping of multiple water-cut products on the same clamping fixture, realize compact layout, and improve debugging efficiency. It mainly includes a main frame plate 1, a fixture platform 2, a pre-pressing module 3, a rotating component 4, a rotating shaft floating mechanism 5 and an end limit component 6. Here, this patent mainly realizes the following three actions through each module, pre-pressing, adjusting the position of the two ends of the water-cut 28, and floating pressing to maintain a floating state.

[0031] Specifically, the patent has two groups of jig platforms 2, which are symmetrically arranged on the main frame plate 1. Multiple water cuts 28 to be clamped are arranged horizontally on the two groups of jig platforms 2. The jig platform 2 and the main frame plate 1 can be connected by linear movement left and right, so that the left and right direction of the jig platform 2 can be adjusted to suit water cuts 28 of different lengths. As an optimization, a positioning pin assembly 7 is provided on the lower side of the jig platform 2, and a detection element 8 is provided on the upper side of the jig platform 2. After the jig platform 2 moves linearly, the positioning pin assembly 7 is used to accurately position the jig platform 2, and the detection element 8 is used to record and identify the product type.

[0032] The biggest innovation of this patent is not direct compression. This is because the water cut 28 needs to be kept in a floating state during milling, so that the force of the water cut 28 is released to prevent deformation. Therefore, as an optimization, this patent first uses a pre-pressing module 3 for pre-pressing. Here, the pre-pressing module 3 is longitudinally arranged at the end of the fixture platform 2 and is used to pre-press the ends of multiple water cuts 28. The pre-pressing module 3 includes a rotating arm member 9, and the rotating arm member 9 is longitudinally pressed on the multiple water cuts 28 as a whole. The pre-pressing module 3 is driven to move by a rotating component 4. Here, the rotating component 4 is arranged at the end of the fixture platform 2 and connected to the pre-pressing module 3. The rotating component 4 can drive the pre-pressing module 3 to rotate and press to the end of the fixture platform 2, wherein the rotating component 4 includes There are a rotating cylinder 10, a rotating shaft 11 and a swing arm 12. The rotating cylinder 10 is connected to the rotating shaft 11, the rotating shaft 11 is connected to one end of the swing arm 12, and the other end of the swing arm 12 is connected to the rotating arm 9. A limiting contact surface 13 is provided on one side of the swing arm 12, which can further limit the rotation position. The rotating arm 9 is longitudinally pressed on multiple water cuts 28 as a whole through the action of the swing arm 12. When pre-pressing, the rotating cylinder 10 can drive the rotating shaft 11 to rotate, and the rotating shaft 11 can drive the swing arm 12 to move, and the swing arm 12 movement can drive the rotating arm 9 to move, so that the rotating arm 9 is first pre-pressed on the water cut 28. Here, it is necessary to stop after pre-pressing, such as Figure 5 As shown, the rotating arm member 9 includes a rotating matching portion 14, the surface of the rotating matching portion 14 has a shape matching the outer shape of the water cut 28, and stop members 15 are arranged on the upper and lower ends, the stop member 15 is linked with the rotating arm member 9, a stop pin 16 is arranged on the stop member 15, a mounting seat 17 is arranged on the stop pin 16, the stop pin 16 is located in the mounting seat 17, the rear end of the stop pin 16 is respectively provided with a connecting head 18 and a stop cylinder 19, and the front end of the stop pin 16 is provided with an inch sleeve 20, the stop pin 16 is pressed on the stop member 15, and the stop cylinder 19 is used to drive the stop pin 16 to move, thereby stopping the rotating arm member 9.

[0033] like Figure 3 and Figure 4As shown, in order to adjust the length state of the two ends of the water cut 28, the fixture also includes an end limit component 6, which is mainly arranged at the end of the fixture platform 2 and is used to limit the positioning of the two ends of multiple water cuts 28. Here, the end limit component 6 includes a limit cylinder 21, a limit linear guide 22, a limit slider 23 and an end positioning span block 24. The limit slider 23 is sleeved on the limit linear guide 22, and the end positioning span block 24 is installed on the limit slider 23. The output end of the limit cylinder 21 is connected to the limit slide, and the end positioning span blocks 24 on both sides adjust the end position of the water cut 28 and position it. Here, the limit cylinder 21 can be used to move the end positioning span block 24, and the horizontal placement position of the water cut 28 can be accurately adjusted by squeezing at both ends, thereby ensuring the stability of subsequent milling.

[0034] In this patent, after pre-pressing, the rotating cylinder 10 needs to be withdrawn and the water cut 28 is kept in a floating state. As an optimization, the fixture also includes a rotating shaft floating mechanism 5, which is arranged on the pre-pressing module 3 and acts on the water cut 28 to keep the water cut 28 in a floating state. The rotating shaft floating mechanism 5 includes a main clamping cylinder 25, a floating member 26 and a clamping member 27. The output end of the main clamping cylinder 25 is connected to the floating member 26, and the lower end of the floating member 26 is connected to the clamping member 27. After the rotating cylinder 10 is withdrawn, the floating member 26 keeps the water cut 28 in a floating state. Here, when the force of the rotating cylinder 10 is released, the main clamping cylinder 25 and the floating member 26 are used to make the entire water cut 28 in a floating state. The entire main clamping cylinder 25 can rotate to drive the shaft 11 to float freely, so as to achieve reliable clamping of multiple products.

[0035] When the entire fixture is working, multiple water-cut 28 products are placed on multiple fixture platforms 2 of the fixture, and the rotating cylinder 10 stops after being pressed into place, and then the force of the rotating cylinder 10 is removed to make it in a free state, and then 10 main clamping cylinders 25 clamp at the same time, and the shaft 11 is driven to float freely by rotating around the rotating axis to achieve reliable clamping of multiple products. Since the linear cylinder and the rotary cylinder 10 are used as power elements, the purpose of reliable clamping of multiple water-cut 28 products at one time is achieved in the present invention, which adapts to the production requirements of clamping multiple products at one time and quickly switching different lengths in the milling production process of aluminum water-cut 28 trim products in the current automotive industry.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
