[0002] The crossbar of the tray table is an important component in the manufacture of tray tables, such as... Figure 1 As shown, the existing tray table cross tube 1 is made of a round tube with a diameter of 15mm, a wall thickness of 0.9mm, and a length of 451mm. It has three threaded holes 2 and two suction cup holes 3. The three threaded holes and the two suction cup holes are on the same straight line.

[0044] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0045] Example: Figure 2 As shown, a fully automatic pallet table horizontal tube processing equipment includes a frame 4, on which a truss device 5 is installed; the frame is as follows Figure 3 As shown;

[0046] like Figure 4 and Figure 5 As shown, the truss device includes a top plate 17, a truss 18, and a movable plate 20. The top plate is fixedly connected to the frame via a gantry frame 16. The truss is mounted on the top plate and moves up and down along both sides of the top plate. A servo electric cylinder 23 is fixedly mounted on the top plate. The output shaft 21 of the servo electric cylinder is fixedly connected to the truss. Slide rails 19 are respectively provided on both sides of the truss. The movable plate is slidably connected to the slide rails. The movable electric cylinder is fixedly mounted on the truss. The output end of the movable electric cylinder is fixedly connected to the movable plate.

[0047] The machine frame, located below the top plate, is equipped with the following stations in sequence: 6 (feeding station), 7 (chamfering station), 8 (intermediate threaded hole processing station), 9 (intermediate flattening station), 10 (straightening station), 11 (end-end suction cup hole punching station), 12 (end-end flattening station), 13 (end-end flattening threaded hole processing station), 14 (end-end arc cutting station), and 15 (threaded hole tapping station). Each of these stations—feeding station, chamfering station, intermediate threaded hole processing station, intermediate flattening station, straightening station, end-end suction cup hole punching station, end-end flattening station, end-end flattening threaded hole processing station, end-end arc cutting station, and threaded hole tapping station—is equipped with a feeding device, a chamfering device, an intermediate threaded hole processing device, an intermediate flattening device, a straightening device, an end-end suction cup hole punching device, an end-end flattening device, an end-end flattening threaded hole processing device, an end-end arc cutting device, and a threaded hole tapping device.

[0048] Each of the ten workstations on the moving plate is equipped with a finger cylinder 22. The moving plate is controlled by the moving electric cylinder. The finger cylinders move back and forth between the current workstation and the next workstation. The workpiece placement distance between each workstation is the same.

[0049] When in use, the gantry device is used to transfer workpieces to the next station. After the gripper of the finger cylinder holds the workpiece, a servo cylinder lifts the gantry, while a moving cylinder drives the gantry to move horizontally, transferring the workpiece to the next station. Then, a servo cylinder lowers the gantry, and the finger cylinders move the workpiece to the next station. The gripper is then released, and the workpiece is placed in its designated position at the next station. The gantry is then lifted and driven back to its original position by the moving cylinder. Each of the ten stations on the gantry is equipped with a finger cylinder, which moves back and forth between the current station and the next station. A discharge port is provided at the final station for unloading.

[0050] like Figure 6 As shown, the feeding device includes a support 24, a base plate 25, and a feeding hopper 26. A feeding cylinder 27 is fixedly installed on the support, and a feeding top block 28 is installed at the output end of the feeding cylinder. A positioning plate is installed on the base plate, and a positioning groove 29 is installed on the positioning plate. The feeding cylinder drives the feeding top block to transport the workpiece output from the bottom outlet of the feeding hopper to the positioning groove to complete the feeding. An infrared sensor 31 is installed on the positioning plate corresponding to the position of the positioning groove. Pushing and clamping cylinders 30 are installed on both sides of the positioning groove on the base plate.

[0051] When the feeding device is in use, the feeding cylinder is activated and rises, conveying the workpiece output from the bottom outlet of the feeding hopper to the positioning slot through the feeding top block to complete the feeding. The two sides of the feeding top block are inclined, and the inner side can only accommodate one workpiece at a time. After feeding, the workpiece automatically falls into the positioning slot. At this time, as soon as the infrared sensor detects that the workpiece has been positioned, it activates the pushing and clamping cylinders on both sides. The pushing and clamping cylinders drive the workpiece to the center for alignment, completing the entire feeding process. After feeding, the workpiece is moved to the next station by the gantry combined with the finger cylinder.

[0052] like Figure 7 As shown, the chamfering device includes a base plate 32, with three positioning posts 33 in the middle of the base plate. Each positioning post has a corresponding workpiece positioning groove for positioning and placing the workpiece. Guide rails 36 are positioned on both sides of the base plate, with sliding seats 37 slidably connected to each guide rail. A chamfering motor 39 is fixedly connected to the sliding seat, and a chamfering head 40 is fixedly connected to the output end of the chamfering motor. Servo cylinders 28 are fixedly installed at both ends of the base plate, with their output ends fixedly connected to the sliding seat. A clamping cylinder 34 is positioned on the top plate corresponding to the workpiece placement position, and an infrared sensor 35 is positioned on the base plate corresponding to the workpiece placement position. A protective cover 41 is provided on the sliding seat at the chamfering head, and chip removal ports 42 are provided on both ends of the base plate corresponding to the workpiece placement position.

[0053] When using the chamfering device, the workpiece is first clamped and placed into the workpiece positioning slot of the three positioning pillars using a finger cylinder. Infrared sensor two detects that the workpiece has been positioned, and the clamping cylinders on both sides of the top plate press down, pressing the workpiece firmly in place. To prevent the workpiece from moving, two chamfering motors start, driving the chamfering head to rotate. Simultaneously, servo cylinder two starts and extends, moving the chamfering head towards both ends of the workpiece to perform chamfering. This solves the problem of uneven workpiece length and burrs during workpiece unloading. During chamfering, the flying debris is protected by a protective cover and falls into the bottom chip discharge port. After chamfering is complete, servo cylinder two retracts, the chamfering motors shut off, clamping cylinder one returns to its original position, and then the finger cylinder moves the workpiece to the next station.

[0054] like Figure 8 As shown, the intermediate tooth hole processing device includes a base plate 3 43. The base plate 3 has two positioning posts 2 44 on either side and a central positioning seat 1 45. Positioning posts 2 and positioning seat 1 have corresponding workpiece positioning grooves for positioning and placing the workpiece. Guide rails 2 48 are correspondingly arranged on both sides of the base plate 3. Moving seats 2 49 are slidably connected to guide rails 2.

A bottom cylinder 46 is arranged at the bottom of the base plate corresponding to the workpiece placement center. A pressing plate 1 54 is fixedly connected to the output end of the pressing cylinder 1. A pressing punch is fixedly installed at the bottom center of the pressing plate 1. A bottom punch is fixedly installed at the output end of the bottom cylinder. An infrared sensor 3 52 is arranged on the base plate 3 corresponding to the workpiece placement position. Below the lower pressure plate, a pre-tightening pressure plate 53 is provided via a guide shaft and a spring. The center of the pre-tightening pressure plate 53 has an opening corresponding to the lower pressure punch, and the positioning seat 53 has an opening corresponding to the bottom punch. The end of the top pressure mandrel 53 has an opening corresponding to both the lower pressure punch and the bottom punch.

[0055] When using the intermediate thread hole machining device, the workpiece is first clamped and placed into the workpiece positioning groove on the positioning column two and positioning seat one by the finger cylinder. At this time, the infrared sensor three senses that the workpiece has been positioned, and the servo cylinders three at both ends are activated, driving the top pressure mandrel one to insert into the workpiece for support during punching and to prevent workpiece deformation. Then, the lower pressure cylinder one and the bottom cylinder are activated simultaneously, driving the lower pressure punch and the bottom punch to complete the punching of the workpiece. When the lower pressure cylinder presses down, the pre-tightening plate one first presses against the positioning seat one to clamp the workpiece. At the same time, the lower pressure plate one drives the lower pressure punch to overcome the spring force and continue to press down to punch. The upper part of the workpiece is punched for thread holes, and the lower part is punched for positioning holes. After punching is completed, the lower pressure cylinder one and the bottom cylinder return to their original positions, the servo cylinder three returns to its original position, and then the finger cylinder drives the workpiece to the next station.

An opening is provided at the center of the pre-tightening plate 2 corresponding to the flattening punch. A positioning spring pin 1 61 is located at the center of the positioning seat 2.

[0057] When using the intermediate flattening device, the workpiece is first clamped and placed into the workpiece positioning groove on the positioning column three and positioning seat two by the finger cylinder. The positioning spring pin one is inserted into the center positioning hole at the bottom of the workpiece for positioning. At this time, the infrared sensor four senses that the workpiece has been positioned, and the lowering cylinder two is activated, driving the lowering plate two to press down. During the pressing, the pre-tightening plate two first presses against the positioning seat two to clamp the workpiece. At the same time, the lowering plate two drives the flattening punch to overcome the spring force and continue to press down to complete the flattening at the intermediate tooth hole. After the flattening is completed, the lowering cylinder two returns to its original position, and then the finger cylinder drives the workpiece to the next station.

[0058] like Figure 10 As shown, the straightening device includes a base plate 64, with two positioning posts 65 on either side and a central positioning seat 66 in the middle. The positioning posts 65 and the positioning seat 66 have corresponding workpiece positioning grooves for positioning and placing the workpiece.

An infrared sensor 67 is installed on the base plate corresponding to the workpiece placement position. A positioning spring pin 70 is located at the center of the positioning seat 66.

[0059] When using the straightening device, the workpiece is first clamped and placed into the workpiece positioning groove on the positioning column four and positioning seat three using the finger cylinder. The positioning spring pin two is inserted into the center positioning hole at the bottom of the workpiece for positioning. At this time, the infrared sensor five senses that the workpiece has been positioned, and the clamping cylinder two starts to clamp the workpiece. Then, the straightening cylinder starts to press down to straighten the workpiece. The straightening cylinders at both ends can adjust the stroke and the amount of deformation to solve the problem of workpiece deformation and non-straightness caused by flattening. After straightening, all cylinders retract, and then the finger cylinder moves the workpiece to the next station.
