[0030] See Figures 1-4 , Figure 1 This is a schematic diagram of the automated punching equipment for umbrella short tubes in the embodiment. Figure 2 This is a schematic diagram of the conveying device, supporting device, tilting device, and chamfering device in the embodiment. Figure 3 This is a schematic diagram of the conveying device structure in the embodiment. Figure 4 for Figure 3 Enlarged view of section A. This example illustrates an automated punching device for umbrella short tubes, comprising a machine base 1, a conveying device 2, a supporting device 3, a flipping device 4, and a punching device 5. Specifically, the conveying device 2 includes a clamping mechanism 21 and a three-axis conveying mechanism 22. The clamping mechanism 21 includes multiple first clamping components 211, arranged along the Y-axis on the machine base 1. The three-axis conveying mechanism 22 includes a first gantry frame 221, a three-axis drive mechanism 222, and multiple second clamping components 223. The first gantry frame 221 is mounted on the machine base 1 along the Y-axis and is located above the multiple first clamping components 211. The three-axis drive mechanism 222 is mounted on the first gantry frame 221. The multiple second clamping components 223 are arranged sequentially along the Y-axis on the three-axis drive mechanism 222. The support device 3 and the conveying device 2 are arranged side by side on the machine base. The support device 3 includes two support mechanisms 31 arranged along the Y-axis, each facing a first clamping assembly 211. A tilting mechanism 4 is located between the two support mechanisms 31, also facing a clamping assembly 211. The stamping device 5 includes a second gantry 51 and two stamping mechanisms 52. The second gantry 51 is mounted between the conveying device 2 and the support device 3. The two stamping mechanisms 52 are arranged along the Y-axis on the second gantry 51, with each stamping mechanism 52 located between the support mechanism 31 and the first clamping assembly 211. During operation, the three-axis drive mechanism 222 can drive the conveying device 2 to move along the X, Y, and Z axes.

[0031] In practice, a vibratory feeder can be installed on the machine base 1 for feeding, and the discharge end of the vibratory feeder can be set at one end of the three-axis conveyor mechanism 22.

[0032] The number of the second clamping assemblies 223 is greater than the number of the first clamping assemblies 211, and in this example, the number of the second clamping assemblies 223 is one more than the number of the first clamping assemblies 211. Preferably, the machine table 1 is provided with a blanking hole 11, which is arranged behind the multiple sets of first clamping assemblies 211 along the Y-axis direction. In the initial state, the last set of second clamping assemblies 223 in the Y-axis direction is directly opposite the blanking hole 11, and the remaining four sets of second clamping assemblies 223 are respectively located above a set of first clamping assemblies 211, and the second clamping assemblies 223 are staggered with the first clamping assemblies 211 in the X-axis direction. The multiple sets of second clamping assemblies 223 sequentially clamp the short pipes to the multiple sets of first clamping assemblies 211.

[0033] Specifically, during operation, under the drive of the three-axis drive mechanism 222, the multiple second clamping assemblies 223 all move towards the vibration disc direction, wherein the first second clamping assembly 223 in the Y-axis direction moves above the vibration disc and downwardly clamps the short pipe from the vibration disc, then the second clamping assembly 223 is reset above the first clamping assembly 211 and places the short pipe on the first clamping assembly 211. When the short pipe reaches the first clamping assembly 211, the first clamping assembly 211 fixes one end of the short pipe, at the same time, the first support device 3 moves towards the short pipe and supports the other end of the short pipe to prevent the short pipe from deforming during the punching process. At this time, the second clamping assembly 223, at this time, the second second clamping assembly 223 is above the first clamping assembly 211, so it can be understood that when the first second clamping assembly 223 clamps the short pipe from the vibration disc to the first clamping assembly 211, the second second clamping assembly 223 clamps the short pipe from the first clamping assembly 211 to the second clamping assembly 211. When the short pipe is located in the second set of first clamping assemblies 211, the turnover mechanism 4 moves towards the short pipe and clamps the other end of the short pipe to rotate it, and then the third set of second clamping assemblies 223 clamps it to the third set of first clamping assemblies 211 for punching. Finally, the last second clamping assembly 211 clamps the finished short pipe into the blanking hole 11, thus realizing the full-automatic punching of different surfaces of the regular hexagonal short pipe, greatly improving the production continuity and thus the production efficiency.

[0034] The three-axis drive mechanism 222 includes a lifting mechanism 2221, an X-axis translation mechanism 2222, and a Y-axis drive mechanism 2223. The lifting mechanism 2221 includes two sets of Z-axis drive assemblies 22211, which are arranged at the two ends of the first gantry 221. The three-axis conveying mechanism 22 is respectively installed at the driving ends of the two sets of Z-axis drive assemblies 22211.

[0035] The X-axis translation mechanism 2222 comprises an X-axis translation plate 22221 and two groups of first X-axis driving assemblies 22222, the two groups of first X-axis driving assemblies 22222 are respectively arranged at the two groups of Z-axis driving assemblies 22211, and the two ends of the X-axis translation plate 22221 are respectively installed on the driving ends of the two groups of first X-axis driving assemblies 22222. It can be understood that, in work, the X-axis translation plate 22221 moves away from the support device 3 under the driving of the first X-axis driving assembly 22222, so that the second clamping assembly 223 moves away from the movement path of the stamping device 5, and the overall layout of the equipment is more compact, and the equipment volume is reduced.

[0036] The Y-axis driving mechanism 2223 comprises a Y-axis driving assembly 22231 and a Y-axis translation plate 22232, the Y-axis driving assembly 22231 is arranged on the X-axis translation plate 22221 along the Y-axis direction, the Y-axis translation plate 22232 is installed on the Y-axis driving assembly 22231, and a plurality of second clamping assemblies 223 are arranged on the Y-axis translation plate 22232. In this example, the Z-axis driving assembly 22211, the first X-axis driving assembly 22222 and the Y-axis driving assembly 22231 are composed of a cylinder, a sliding rail and a sliding block.

[0037] Further, the clamping mechanism 21 further comprises a clamping mounting frame 212, the clamping mounting frame 212 is arranged on the machine table 1 along the Y-axis direction, and a plurality of first clamping assemblies 211 are arranged on the clamping mounting frame 212.

[0038] The first clamping assembly 211 comprises a first clamping driving 2111 and two first clamping blocks 2112, the first clamping driving 2111 is fixed on the clamping mounting frame 212, the two first clamping blocks 2112 are arranged on the driving end of the first clamping driving 2111, the side wall of the first clamping block 2112 is provided with a first clamping opening 21121, the first clamping openings 21121 of the two first clamping blocks 2112 are opposite to each other, and the first clamping driving 2111 makes the two first clamping blocks 2112 close to or away from each other. In work, the first clamping driving 2111 drives the two clamping blocks 2112 to move towards each other, so that the two first clamping openings 21121 clamp the short pipe, in this example, when the two first clamping openings 21121 are close to each other, a regular hexagonal clamping space is formed between the two first clamping openings 21121 to adapt to the shape of the short pipe and prevent the short pipe from turning and deviating during punching. In this example, the first clamping driving 2111 adopts a parallel pneumatic clamping jaw.

[0039] Similarly, the second clamping assembly 223 also includes a second clamping drive 2231 and two second clamping blocks 2232, the two second clamping drives 2231 are installed on the driving end of the second clamping drive 2231, the second clamping block 2232 has a second clamping opening 22321, the second clamping openings 22321 of the two second clamping blocks 2232 are opposite, the second clamping drive 2231 makes the two second clamping blocks 2232 approach or move away from each other, and the second clamping block 2232 is arranged opposite to the first clamping block 2112. Among them, when the two second clamping openings 22321 are close to each other, a regular hexagonal clamping space is also formed to prevent the short tube from turning and deviating. Among them, the second clamping drive 2231 also adopts a parallel pneumatic clamping jaw.

[0040] Further, the support device 3 includes a second X-axis drive assembly 31, an X-axis translation frame 32, and a support head 33. The second X-axis drive assembly 31 is arranged on the machine table 1 along the X direction. The X-axis translation frame 32 is installed on the second X-axis drive assembly 31. The support head 33 is arranged on the X-axis translation frame 32 and is opposite to the clamping space of the first clamping assembly 211. In operation, under the drive of the second X-axis drive assembly 31, the X-axis translation frame 32 moves towards the first clamping assembly 223, so that the support head 33 inserts one end of the short tube to form a support. In this way, the short tube is uniformly stressed during punching, effectively preventing the short tube from deforming. Preferably, the cross-sectional shape of the support head 33 is a regular hexagon. In this example, the second X-axis drive assembly 31 also consists of a cylinder, a slider, and a slide rail.

[0041] Among them, one end of the second X-axis drive assembly 31 is located on the side of the first gantry 221 away from the second gantry 51, and the other end extends through the bottom of the clamping mounting frame 212 to the other side of the second gantry 51. In this way, the overall layout of the device is further compacted, and the device volume is further reduced.

[0042] Referring to Figure 5 , referring to Figures 1-4 , Figure 5 is a schematic view of the support device structure in the embodiment.

[0043] Preferably, the supporting device 3 further comprises a demolding mechanism 34, which comprises a mold frame 341 and a demolding drive 342. The mold frame 341 comprises a fixed block 3411, a baffle 3412 and a fixed plate 3413. The fixed block 3411 is fixed to the X-axis translation frame 32. The baffle 3412 is fixed to one end of the fixed block 3411 close to the clamping mechanism 21. The fixed plate 3413 is fixed to the other end of the fixed block 3411. The demolding drive 342 is arranged on the side of the fixed plate 3413 away from the baffle 3412. The driving end of the demolding drive 342 penetrates the fixed plate 3413 and the baffle 3412 in sequence. The supporting head 33 is installed on the driving end of the demolding drive 342. When the supporting head 33 is inserted into the short pipe, the baffle 3412 abuts against one end of the short pipe. It can be understood that when it is needed to make the supporting head 33 separate from the short pipe, the supporting head 33 is first driven by the demolding drive 343 to move away from the short pipe. Since the baffle 3412 abuts against the short pipe, when the supporting head 33 is pulled out from one end of the short pipe, the baffle 3412 can effectively play a limiting effect on the short pipe, preventing the short pipe from falling off from the first clamping assembly 211 due to stress when the supporting head 33 is pulled out. After the supporting head 33 is pulled out, the X-axis translation frame 32 can be driven by the second X-axis driving assembly 31 to move so that the supporting head 33 moves away from the short pipe. In this example, the demolding drive 342 is a pneumatic cylinder.

[0044] Referring to Figure 6 , referring to Figures 1-4 , Figure 6 is a schematic view of the structure of the overturning device in the embodiment. Further, the overturning mechanism 4 comprises a third X-axis driving assembly 41, an overturning driving assembly 42 and an overturning head (not shown in the figure).

The overturning head (not shown in the figure) is installed on the overturning driving assembly 42. One end of the overturning head 42 is opposite to the first clamping assembly 211. The cross section of the overturning head 42 is a regular hexagon. In operation, when the short pipe is placed on the Y-axis and clamped by the second set of first clamping assemblies 211, the third X-axis driving assembly 41 drives the overturning head (not shown in the figure) to move towards the short pipe and insert into the other end of the short pipe. At this time, the first clamping assembly 211 releases the clamping. The overturning driving assembly 42 drives the overturning head (not shown in the figure) to overturn, so that the short pipe is overturned. Subsequently, when the short pipe is clamped by the second clamping assembly 223, the third X-axis driving assembly 41 drives the overturning driving assembly 42 to move away from the short pipe, so that the overturning head (not shown in the figure) separates from the short pipe. In this example, the third X-axis driving assembly 41 also comprises a pneumatic cylinder, a sliding block and a sliding rail. The overturning driving assembly 42 is a servo motor.

[0045] The stamping mechanism 52 comprises a stamping driving member 521 and a stamping head (not shown in the figure), the stamping driving member 521 is fixed on the top of the second gantry 51, the driving end of the stamping driving member 521 penetrates through the second gantry 51 and suspends above the first clamping assembly 211, the stamping head is installed on the driving end of the stamping driving member 521, wherein the stamping driving member 521 adopts a gas-liquid supercharged cylinder.

After the chamfering is completed, the short pipe is clamped by the second clamping assembly 223 to the blanking opening 11 for collection. In the embodiment, the chamfering driving assembly 61 is composed of a gas cylinder, a sliding rail and a sliding block.
