By setting a multi-point limit component, before punching, the small two-way air pump 14 will successively supply air to the inside of the pneumatic arc telescopic rod 13 through the air delivery pipe 17, the air distribution pipe 15 and each three-way control valve 16 and the air delivery seat 12, so that the pneumatic arc telescopic rod 13 begins to extend under the action of air pressure, thereby driving the adjustment electric push rod 10 to rotate toward the parts through the rotating bracket 9 until the positioning bracket 11 presses on the parts to limit the parts, thereby facilitating punching. When the parts need to be adjusted When performing continuous drilling, the small two-way air pump 14 can first evacuate air to reset each pneumatic arc telescopic rod 13 and the rotating bracket 9, and then control the opening and closing of each three-way control valve 16 on both sides to keep a gas supply seat 12 on each side connected to the gas distribution pipe 15, and then supply air to limit the accessories of the corresponding two positioning frames 11, so as to realize the selection and change of the limit point position, so that the adjustment electric push rod 10 that would hinder the drilling operation of the punching machine 6 will avoid the punching machine 6, which is convenient for the continuous drilling operation. By setting the self-driving trolley 7, when it is necessary to perform multi-station drilling on the accessories, multiple drilling tables 1 loaded with the punching machines 6 can be arranged together in sequence, so that each trolley track 101 can be connected to each other, so that the self-driving trolley 7 can carry the accessories and move back and forth on each drilling table 1 along the trolley track 101, so that the accessories can not only accept continuous drilling, but also realize multi-station drilling, so as to obtain more comprehensive and flexible drilling processing.

[0020] like Figure 7 As shown, the positioning frame 11 is threaded with an adjusting screw 18, and the bottom end of the adjusting screw 18 is fixedly installed with a suction cup 19; specifically, by arranging the adjusting screw 18 and the suction cup 19, the adjusting screw 18 can adjust the height of the bottom suction cup 19, and cooperate with the electric push rod 10 to adjust the position of the positioning frame 11, so that the suction cup 19 can be adjusted according to the thickness of different plates, thereby obtaining a larger adjustment range, so that the limit point can avoid the punch 6 as much as possible, and at the same time the suction cup 19 can increase the clamping force on the accessories.

[0021] like Figure 4 As shown, an air chamber is provided inside the self-driving trolley 7, and a plurality of evenly distributed dust suction holes 702 are provided on the inner wall of the placement groove 701, and the dust suction holes 702 are all connected to the inside of the air chamber. A dust suction pipe 20 connected to the inside of the air chamber is fixedly installed at the bottom of the self-driving trolley 7, as shown in FIG. Figure 1As shown, a vacuum cleaner 21 is provided on one side of the punching table 1, and the suction end of the vacuum cleaner 21 is fixedly connected to one end of the dust suction pipe 20; specifically, by providing the vacuum cleaner 21, the vacuum cleaner 21 is started in advance before punching, so that the vacuum cleaner 21 generates a certain suction force on the inside of the placement groove 701 through the dust suction pipe 20, the air chamber inside the self-propelled trolley 7 and the dust suction hole 702, so that the accessories can be adsorbed in the placement groove 701, thereby improving the limiting effect of the accessories. At the same time, the vacuum cleaner 21 absorbs the waste chips generated by punching the accessories, thereby reducing the accumulation of waste chips on the punching table 1.

[0022] like Figure 1 As shown, a mobile cart 22 compatible with the vacuum cleaner 21 is provided on one side of the punching table 1, and the vacuum cleaner 21 is placed on the top of the mobile cart 22. In this embodiment, a guide rail compatible with the mobile cart 22 can be provided on one side of the punching table 1 to limit the moving trajectory of the mobile cart 22, and a plurality of evenly distributed synchronous frames 23 are fixedly installed between the self-driving trolley 7 and the vacuum cleaner 21; specifically, by providing the mobile cart 22, when the self-driving trolley 7 is placed, the vacuum cleaner 21 is placed on the top of the mobile cart 22, and when the self-driving trolley 7 moves back and forth on each punching table 1 along the trolley track 101, the self-driving trolley 7 will drive the vacuum cleaner 21 to move synchronously through the plurality of synchronous frames 23, so that the self-driving trolley 7 moves with the self-driving trolley 7 with the help of the mobile cart 22, so that the accessories can always receive the negative pressure limit and dust collection treatment of the vacuum cleaner 21.

[0023] like Figure 5 As shown, a positioning rod 24 is fixedly installed at the bottom of the self-driving vehicle 7. Figure 2 As shown, a horizontally arranged positioning electric push rod 25 is fixedly installed on the top of the punching table 1. Figure 8 As shown, the telescopic end of the positioning electric push rod 25 faces the self-propelled trolley 7 and is fixedly installed with a positioning fork frame 26, which is slidably installed on the top of the punching table 1 and adapted to the positioning rod 24; specifically, by setting the positioning fork frame 26, after the self-propelled trolley 7 is placed on the punching table 1, the self-propelled trolley 7 carrying the accessories moves to the center position of the top of the punching table 1, at this time, the positioning electric push rod 25 on the top of the punching table 1 will drive the positioning fork frame 26 to move toward the self-propelled trolley 7, so that the positioning fork frame 26 is docked with the positioning rod 24 at the bottom of the self-propelled trolley 7, so that the positioning fork frame 26 is inserted on both sides of the positioning rod 24 to limit the positioning rod 24, and then the self-propelled trolley 7 as a whole is limited to prevent the self-propelled trolley 7 from shaking back and forth in a small range along the trolley track 101 during the punching process, thereby affecting the punching quality.

[0024] like Figure 8As shown, the positioning fork frame 26 is fixedly installed with flaring guide rods 27 at both ends of the positioning rod 24, and the two flaring guide rods 27 are symmetrically arranged and bent toward one side away from each other; specifically, by setting the flaring guide rods 27, when the self-driving trolley 7 carrying the accessories moves along the trolley track 101 to the center position of the top of the punching table 1, if the self-driving trolley 7 does not move into place, the positioning rod 24 and the positioning fork frame 26 at the bottom of the self-driving trolley 7 will be slightly misaligned. When the positioning electric push rod 25 drives the positioning fork frame 26 to move toward the positioning rod 24, the two flaring guide rods 27 at both ends of the positioning fork frame 26 will use their own side surfaces to apply pressure to the positioning rod 24, so that the pressure of the flaring guide rods 27 automatically moves to the correct position, thereby realizing the correction of the position of the self-driving trolley 7.

[0025] like Figure 2 As shown, a plurality of evenly distributed splicing grooves 102 are provided on both sides of the top of the punching table 1. Figure 3 As shown, a plurality of splicing threaded holes 103 are provided on the inner wall of the splicing groove 102; specifically, by providing the splicing groove 102, when performing multi-station punching, a plurality of punching tables 1 loaded with punching machines 6 are arranged together in sequence, so that the punching tables 1 are close to each other, and two adjacent groups of splicing grooves 102 are butted against each other. At this time, a plate with assembly holes is placed on the same group of splicing grooves 102, and the plate is screwed into the two splicing threaded holes 103 by using fastening bolts and splicing threaded holes 103, so that the plurality of punching tables 1 are locked and fixed to prevent the punching tables 1 from shaking and shifting during the punching operation.

[0026] like Figure 3 As shown, locking ring frames 28 are fixedly installed on the side walls of the four corners of the top of the punching table 1, and the locking ring frames 28 located on the same side correspond to the positions of the splicing grooves 102; specifically, by setting the locking ring frames 28, before using the plate and the splicing threaded holes 103 and the splicing grooves 102 to lock multiple punching tables 1, as the punching tables 1 are pressed against each other, adjacent locking ring frames 28 will also be pressed against each other, and then fastening bolts are installed on the same group of locking ring frames 28, so that the fastening bolts narrow the gaps at the tops of adjacent punching tables 1, facilitate the assembly of the plate and the splicing grooves 102, and prevent the existence of a large gap between two adjacent punching tables 1 due to factors such as tolerance, which makes it difficult to align the assembly holes on the plate and the splicing threaded holes 103.

[0027] In summary: when the automobile parts processing and punching equipment is in use, the plate parts that need to be punched are first placed in the placement slot 701, so that the self-driving trolley 7 can carry the parts and move on the punching table 1, and the punching machine 6 is driven by the three axes of the electric slider, the horizontal electric slide 4 and the vertical electric slide 5 to move above the parts, and the parts are punched. By setting a multi-point limit assembly, before punching, the small two-way air pump 14 will sequentially supply air to the inside of the pneumatic arc telescopic rod 13 through the air supply pipe 17, the air distribution pipe 15 and each three-way control valve 16, and the air supply seat 12, so that the pneumatic arc telescopic rod 13 begins to extend under the action of air pressure, thereby driving the adjustment electric push rod 10 to rotate toward the parts through the rotating bracket 9 until the positioning bracket 11 is pressed on the parts. The accessories are limited on the parts to facilitate drilling. When it is necessary to drill holes on the accessories continuously, the small two-way air pump 14 can be used to pump air to reset the pneumatic arc telescopic rods 13 and the rotating bracket 9, and then the opening and closing of the three-way control valves 16 on both sides are controlled to keep a gas delivery seat 12 on each side connected to the gas distribution pipe 15, and then the air is delivered to limit the accessories on the corresponding two positioning frames 11, so as to realize the selection and change of the limit points, so that the adjustment electric push rod 10 that will hinder the drilling operation of the punching machine 6 will avoid the punching machine 6, which is convenient for the continuous drilling operation. By setting the self-driving trolley 7, when it is necessary to drill holes on the accessories at multiple stations, multiple punching tables 1 loaded with punching machines 6 can be arranged in sequence. The self-driving trolley 7 can carry the accessories and move back and forth along the trolley track 101 on each punching table 1, so that the accessories can not only be punched continuously, but also can be punched in multiple positions, so as to obtain a more comprehensive and flexible punching process. By setting the adjusting screw 18 and the suction cup 19, the adjusting screw 18 can adjust the height of the bottom suction cup 19, and the electric push rod 10 can adjust the position of the positioning frame 11, so that the suction cup 19 can be adjusted according to the thickness of different plates, so as to obtain a larger adjustment range, so that the limit position can avoid the punching machine 6 as much as possible, and the suction cup 19 can increase the pressing force on the accessories. By setting the vacuum cleaner 21, the vacuum cleaner 21 can be set in advance before punching. Start the vacuum cleaner 21, so that the vacuum cleaner 21 generates a certain suction force on the inside of the placement groove 701 through the vacuum pipe 20, the air chamber inside the self-driving trolley 7 and the vacuum hole 702, so that the accessories can be adsorbed in the placement groove 701, thereby improving the limiting effect of the accessories. At the same time, the vacuum cleaner 21 absorbs the waste generated by punching the accessories to reduce the accumulation of waste on the punching table 1. By setting the mobile cart 22, when placing the self-driving trolley 7, the vacuum cleaner 21 is placed on the top of the mobile cart 22. When the self-driving trolley 7 moves back and forth on each punching table 1 along the trolley track 101, the self-driving trolley 7 will drive the vacuum cleaner 21 to move synchronously through multiple synchronous frames 23, so that the self-driving trolley 7 moves with the self-driving trolley 7 with the help of the mobile cart 22.The accessories can always be subject to the negative pressure limiting and dust collection treatment of the vacuum cleaner 21. By setting the positioning fork frame 26, after the self-driving trolley 7 is placed on the punching table 1, the self-driving trolley 7 carries the accessories and moves to the center position of the top of the punching table 1. At this time, the positioning electric push rod 25 on the top of the punching table 1 will drive the positioning fork frame 26 to move toward the self-driving trolley 7, so that the positioning fork frame 26 is connected with the positioning rod 24 at the bottom of the self-driving trolley 7, so that the positioning fork frame 26 is inserted on both sides of the positioning rod 24 to limit the positioning rod 24, and then the self-driving trolley 7 is limited as a whole to prevent the self-driving trolley 7 from being moved during the punching. During the drilling process, the self-driving trolley 7 will sway back and forth in a small range along the trolley track 101, affecting the drilling quality. By setting the flaring guide rod 27, when the self-driving trolley 7 carrying the accessories moves along the trolley track 101 to the center position of the top of the drilling table 1, if the self-driving trolley 7 does not move into place, the positioning rod 24 and the positioning fork frame 26 at the bottom of the self-driving trolley 7 will be slightly misaligned. When the positioning electric push rod 25 drives the positioning fork frame 26 to move toward the positioning rod 24, the two flaring guide rods 27 at both ends of the positioning fork frame 26 will use their own side surfaces to apply pressure to the positioning rod 24. The pressure of the flaring guide rod 27 is applied to automatically move the flaring guide rod 27 to the correct position, thereby realizing the correction of the position of the self-driving trolley 7. By setting the splicing groove 102, when performing multi-station punching, multiple punching tables 1 loaded with punching machines 6 are arranged in sequence, so that the punching tables 1 are close to each other, and the two adjacent groups of splicing grooves 102 will butt against each other. At this time, a plate with an assembly hole is placed on the same group of splicing grooves 102, and the plate is screwed into the two splicing threaded holes 103 by using fastening bolts and splicing threaded holes 103, so that the multiple punching tables 1 are locked and fixed to prevent the punching tables 1 from being stuck. In case of shaking and deviation during the punching operation, by setting the locking ring frame 28, before the multiple punching stations 1 are locked by using the plate and the splicing threaded holes 103 and the splicing grooves 102, as the punching stations 1 are pressed against each other, the adjacent locking ring frames 28 will also be pressed against each other, and then the fastening bolts are installed on the same set of locking ring frames 28, so that the fastening bolts narrow the gaps at the tops of the adjacent punching stations 1, facilitating the assembly of the plate and the splicing grooves 102, and preventing the existence of a large gap between the two adjacent punching stations 1 due to factors such as tolerance, which makes it difficult to align the assembly holes on the plate with the splicing threaded holes 103.
