[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 As shown, the present invention proposes a TPV tube cutting and pad printing device for a vehicle, comprising a base plate 1, which also comprises at least one group of cutting components 2 slidably connected to the base plate 1, and the sliding connection mode of the cutting components 2 refers to: a third slide rail 37 is arranged on the base plate 1, and a support plate 38 is slidably connected to the third slide rail 37, and a power cylinder 35 is connected to the support plate 38, and the power cylinder 35 pushes the support plate 38 to move laterally, and a fourth slide rail 39 is arranged on the support plate 38 perpendicular to the third slide rail 37, and a carrier plate is connected to the fourth slide rail 39, and a power cylinder 35 is also connected to the same carrier plate, and the power cylinder 35 is used to push the carrier plate to move, and is used to approach or move away from the pipe to be cut, and the pipe is positioned by the pipe support assembly 28 arranged at the end of the cutting component 2.

[0026] Specifically, Figure 6As shown, the pipe support assembly 28 includes a movable carrier, which is connected to the bottom plate 1 through a second slide rail 32, and a push-pull cylinder 33 is connected to the side of the movable carrier. The movable carrier approaches or moves away from the cutting assembly 2 along the second slide rail 32. A profiling bracket 34 is provided on the movable carrier, and a pipe clamping assembly is provided above the profiling bracket 34. The profiling bracket 34 is composed of a plurality of semicircular arc grooves arranged in an array, which are used for the pipe to be pressed on the groove for positioning. Of course, for some special-shaped pipes, more support blocks can be provided on the movable carrier to support the pipe. The movable carrier can be pulled by the push-pull cylinder 33. Approaching or moving away from the cutting assembly 2, so as to adjust the distance between the movable carrier and the cutting assembly 2, and to control the length of the cut pipe. The pipe clamping assembly is composed of a cylinder 35 and a pressing block 36. The cylinder 35 presses down to press the arc-shaped pressing block 36 on the pipe body to ensure that the pipe body can be stabilized during cutting.

[0027] After the pipe is positioned by the above structure, it is cut by the cutting assembly 2. Specifically, Figure 2 As shown, the cutting assembly 2 includes a driving member 3, which can be a motor. The output end of the driving member 3 is connected to a rotating shaft 4, and the output end of the motor and the rotating shaft 4 are connected via a coupling. The end of the rotating shaft 4 is connected to a disk body 5, and the disk body 5 is slidably connected to a cutter assembly 6 in the diameter direction.

[0028] like Figure 3 , Figure 4 As shown, a pulling sleeve is coaxially connected to the rotating shaft 4, a fixed block is connected to the pulling sleeve, a connecting rod 7 is movably connected between the fixed block and the cutter assembly 6, rollers 8 are provided at both ends of the connecting rod 7, the connecting rod 7 passes through the disk body 5 and the rollers 8 are respectively clamped on the fixed block and the cutter assembly 6, the connecting rod 7 is an L-shaped structure, rollers 8 are provided at both ends of the L-shaped structure, a second vertical groove 14 is provided on the side wall of the fixed block, a roller 8 of the connecting rod 7 is pressed in the second vertical groove 14, the The cutter assembly 6 is slidably connected to the first slide rail 9, and the cutter assembly 6 includes a slider 10 clamped on the first slide rail 9, a knife block 11 is fixed on the slider 10, and a cutter 12 is fixed on the knife block 11. The cutters 12 of the two sets of cutter assemblies 6 are arranged opposite to each other, and a first vertical groove 13 is provided on the slider 10. The roller 8 of the connecting rod 7 is clamped in the first vertical groove 13. The side of the disk body 5 is provided with a slot for the connecting rod 7 to pass through the disk body 5, and the L-shaped angle of the connecting rod 7 is directed to the inside of the disk body 5. The approach or distance of the cutter 12 is achieved by pulling the pulling sleeve.

[0029] Specifically, the pulling sleeve includes a guide sleeve 15 sleeved on the connecting shaft, and the two ends of the guide sleeve 15 are respectively connected to a first pull plate 16 and a second pull plate 17, the fixed block is connected to the side wall of the first pull plate 16, and the side wall of the second pull plate 17 is connected to at least one group of pulling cylinders 18. In order to balance the force, two opposite groups of pulling cylinders 18 are arranged on the side wall of the second pull plate 17. The pulling sleeve pushes and pulls the connecting rod 7 to drive the cutter assembly 6 to move closer or farther away from each other. A plurality of guide rods 40 are also arranged between the first pull rod and the disk body 5 to ensure the balance of the movement of the first pull plate 16.

[0030] The specific working method of the cutting assembly 2 is as follows: after the mouth of the pipe is extended to the center position of the plate body 5, the second pull plate 17 is pushed and pulled by pulling the cylinder 18 to push the first pull plate 16 to move, and the fixed block connected to the first pull plate 16 pushes the connecting rod 7. Since the connecting rod 7 is connected to the second vertical groove 14 in the fixed block through the roller 8, while the connecting rod 7 is pushed axially along the rotating shaft 4, the rotation of the connecting rod 7 will drive the cutter assembly 6 connected to the other end thereof to move along the direction of the first slide rail 9, that is, the push and pull of the cylinder 18 can be used to adjust the distance between the two sets of cutters 12. The position between the two ends is adapted to accommodate pipes of different diameters, and the cutter 12 is pressed against the side wall of the pipe. In the present embodiment, since the turning angle of the L-shaped connecting rod 7 is directed into the turntable, when the pulling cylinder 18 contracts and the first pulling plate 16 is pulled back, the two sets of cutter assemblies 6 approach each other, and vice versa, the cutter assemblies 6 move away from each other. The motor drives the rotating shaft 4 to rotate, thereby driving the disc body 5 to rotate, that is, driving the cutter assembly 6 to cut the side wall of the pipe. During the rotation, the cylinder 18 is pulled back to a certain extent, thereby ensuring that the cutter 12 can cut pipes of a certain thickness.

[0031] In this embodiment, in order to facilitate the fixing of the pulling cylinder 18, a shell 19 is provided on the outside of the rotating shaft 4, the pulling cylinder 18 is connected to the shell 19, and a bearing 20 is provided between the rotating shaft 4 and the shell 19 to ensure the connection between the rotating shaft 4 and the shell 19.

[0032] The above process is the cutting process. When the cutting is completed, pad printing can be performed. The pad printing device is located above the cutting position. Since the pad printing position coincides with the position where the pipe clamping assembly presses the pipe, in order to prevent the two from interfering, a supporting bracket 22 is provided on the bottom plate 1. The supporting bracket 22 spans over the cutting assembly 2 and is connected to the pad printing assembly 21. Figure 5As shown, the pad printing assembly 21 includes a pad printing plate 23 fixed on the bearing bracket 22, a push cylinder 24 is provided on one side of the pad printing plate 23, a push frame 25 is connected to the output end of the push rod, a liquid cup 26 is connected to the push frame 25, the push cylinder 24 pushes the liquid cup 26 to move on the pad printing plate 23, and the pad printing plate 23 is provided with an indented marking groove 27. A pad printing module 29 is also provided above the pipe supporting assembly 28, a pressing cylinder 30 is connected to the pad printing module 29, a pad printing block 31 is connected to the output end of the pressing cylinder 30, the pad printing block 31 points to the pipe on the pipe supporting assembly 28, the pad printing block 31 can be moved by the pad printing module 29, and at the same time, the mobile carrier of the pipe supporting assembly 28 also moves in the same direction and distance, ensuring that the pad printing block 31 can move to the top of the cut pipe, solving the problem of interference with the pipe clamping assembly.

[0033] The pad printing assembly 21 is located above the cutting mechanism and has a compact structure. When in use, the push cylinder 24 drives the push frame 25 to control the liquid cup 26 to move into the marking groove 27. After there is ink in the marking groove 27, the pad printing block 31 is pressed on the marking groove 27, and after taking the ink, it is pressed on the pipe fitting to realize pad printing.

[0034] In this embodiment, two groups of cutting components 2 can be set, each group of cutting components 2 can correspond to two groups of pipe fittings, and group cutting can be achieved by moving the cutting components 2. Four groups of pipe fittings can be cut and printed at the same time, which greatly improves efficiency.
