DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical solutions of the embodiments of the present application and the prior art, the specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and those skilled in the art can also obtain other drawings and other implementation manners based on these drawings without creative effort. In addition, the design direction is only to represent the relative position relationship between the components, not the absolute position relationship.

[0028] The utility model discloses a kind of semi-automatic feeding devices of light laser pipe cutting machine, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Mainly including the feeding module 1 butt joint to the side of machine tool 2, feeding module 1 includes multiple parallelly arranged and perpendicular to the feeding arm 11 of machine tool 2 and a datum arm, datum arm is vertically arranged in the rear side of cutting chuck 5 of machine tool 2, multiple feeding arm 11 is sequentially spaced between datum arm and tail end chuck 4 of machine tool 2;Feeding arm 11 is carried with the conveying chain 7 of cyclic operation, the conveying chain 7 is carried with multiple equidistant distribution for limiting the limiting block 8 for limiting pipe 6, the conveying chain 7 on multiple feeding arm 11 is synchronous operation, and the position of limiting block 8 carried on the conveying chain 7 is same, make multiple conveying chain 7 synchronous operation, and the two adjacent limiting blocks 8 of same position on the upper surface of multiple feeding arm 11 are collectively limited to convey a pipe 6.

[0029] In the application, feeding module 1 is the conveying structure of pipe 6, which conveys pipe 6 to a specific position. At this specific position, pipe 6 is received by the floating support device 3 carried by machine tool 2, and is lifted upward to the cutting position, i.e., is butt joint with cutting chuck 5 and tail end chuck 4.

[0030] It can be understood that the position of floating support device 3 is fixed, located directly below the cutting position. The cutting position is projected onto feeding arm 11 to obtain the above-mentioned specific position (hereinafter referred to as projection position). When it is detected that pipe 6 is conveyed to the projection position, the conveying can be stopped, and pipe 6 is lifted upward to the cutting position by floating support device 3.

[0031] At the cutting position, the two ends of pipe 6 are respectively aligned with the center holes of cutting chuck 5 and tail end chuck 4, so that cutting chuck 5 and tail end chuck 4 can clamp pipe 6. In this way, the feeding of pipe 6 is completed. Subsequently, cutting operation can be performed.

[0032] In the embodiment of the application, feeding module 1 should be located between cutting chuck 5 and tail end chuck 4, so that pipe 6 is located between the two chucks, facilitating clamping. In the traditional feeding device, the feeding device is directly butt joint with machine tool 2. The relative position between the conveying position of pipe 6 and the chuck is uncertain, which easily leads to the clamping failure of both ends of the chuck to pipe 6, or the phenomenon that pipe 6 cannot be clamped.

[0033] Based on this, feeding module 1 of the application is positioned and installed based on one chuck on machine tool 2, so that the relative position relationship between at least one end of pipe 6 and the chuck is relatively clear, to facilitate the synchronous clamping of both ends of the chuck to pipe 6.

[0034] In a specific embodiment, in order to better serve the clamping post-processing operation and shorten the feeding cycle, the cutting chuck 5 is selected as the reference, the reference arm is arranged on the machine tool 2, and the plurality of feeding arms 11 are sequentially and spacedly arranged between the reference arm and the tail end chuck 4, which can be equally spaced or unevenly distributed.

[0035] The cutting chuck 5 is closer to the front end of the pipe 6, and the tail end chuck 4 is farther away from the rear end of the pipe 6. When clamping, the running speed and distance of the tail end chuck 4 can be adjusted according to the length of the pipe 6, so that the two chucks can stably and quickly clamp the pipe 6.

[0036] Specifically, the reference arm does not carry a driving structure, and the feeding arm 11 carries a corresponding driving structure for driving the circulating operation of the conveying chain 7.

[0037] Specifically, the reference arm does not carry a driving structure, and the feeding arm 11 carries a corresponding driving structure for driving the circulating operation of the conveying chain 7. Figure 2

[0038] When manually feeding, the front end of the pipe 6 can be close to the reference plate 12, so that the relative position relationship between the pipe 6 and the cutting chuck 5 is more clear, and the clamping operation is facilitated. The feeding end of the feeding arm 11 can be flush with the front end of the reference arm, so that the reference plate 12 has a reference structure at the feeding end, facilitating alignment during manual feeding.

[0039] Specifically, the driving structure can include a driving motor, a gear, etc., and the support structure can include a housing, a support leg, etc., which can be seen from Figure 3

[0040] Specifically, the conveying chain 7 includes a driving chain 71 and a limiting block 8, and the limiting block 8 is fixed to the outer ring side of the driving chain 71 at equal intervals.

[0041] In a specific embodiment, the right and left sides of the driving chain 71 are respectively provided with right and left support members 72 and 73, the limiting block 8 includes a plurality of limiting members, the left side of the limiting member is fixed to the left support member 73, the right side of the limiting member is fixed to the right support member 72, the length of a single limiting member is the same as the length of a single chain structure of the driving chain 71, and a plurality of limiting members are continuously fixed to the driving chain 71 to form a limiting block 8.

[0042] ​​Exemplary, the left and right support members can be symmetrical structures, such as right-angled plates, the right angles facing outward, the vertical plates having two holes for fixing the single chain structure, and the horizontal plates being located on the upper side (the outer side) for fixing the single limiting member. The single limiting member can be a square tube structure with an open bottom wall, the open bottom wall being axially provided to form two symmetrical suspension plates, and the two suspension plates being fixed to the horizontal plates of the two support members, respectively.

[0043] In the embodiment of the present application, the conveying chain 7 is loaded with a plurality of limiting blocks 8 for limiting the pipe 6 at equal intervals, the conveying chains 7 on the plurality of feeding arms 11 are synchronously operated, and the positions of the limiting blocks 8 loaded on the conveying chain 7 are the same, so that when the plurality of conveying chains 7 are synchronously operated, two adjacent limiting blocks 8 located on the upper surfaces of the plurality of feeding arms 11 and having the same position jointly limit the conveying of a pipe 6.

[0044] The plurality of feeding arms 11 should be synchronously operated, so that the operation step distances of the conveying chains 7 loaded on each feeding arm 11 are consistent, at the same time, the lengths of each conveying chain 7 should be consistent, and the intervals of the limiting blocks 8 are also consistent, so that after the conveying chain 7 is assembled on the gear, the positions of the limiting blocks 8 on each feeding arm 11 are the same, so as to realize the synchronous conveying of the pipe 6.

[0045] Each feeding arm 11 only clamps the pipe 6 through the limiting block 8 located on the upper surface, and only one pipe 6 is placed between two adjacent limiting blocks 8, and the trend of the pipe 6 is parallel to the trend of the machine tool 2 after being clamped by the limiting blocks 8 on the plurality of feeding arms 11, as shown in Figure 2 .

[0046] Among them, the upper surface of the feeding arm 11 should have a plurality of limiting blocks 8 at the same time, which can clamp the pipe 6, so that the feeding module 1 can convey a plurality of pipes 6 at the same time, and the plurality of pipes 6 are partitioned and separated by the limiting blocks 8, without disorder, crossing and other phenomena; at the same time, the feeding arm 11 realizes the storage, even if the artificial feeding speed of the feeding end is slow, the efficiency stability of the discharging end can be ensured, for example, the discharging end intermittently conveying the pipe 6 to the floating support device 3 will not greatly affect the feeding period, which still has great advantages compared with the conventional semi-automatic feeding device, and reduces the feeding period.

[0047] In the embodiment of the present application, a plurality of floating support devices 3 are loaded on one side (the side of the mounting chuck) of the machine tool 2 along the trend of the machine tool 2, the plurality of floating support devices 3 can be installed on the rack below the machine tool 2, and the discharging ends of the plurality of feeding arms 11 are located above the rack; the plurality of floating support devices 3 and the plurality of feeding arms 11 can be alternately distributed, and the discharging end of the feeding arm 11 extends to the front of the fixed position of the floating support device 3, and the feeding end of the feeding arm 11 is flush with the front end of the reference arm.

[0048] Exemplarily, the lower end surface of the fixed end 32 of the floating support device 3 is fixed to the pipe top surface of the machine tool, and the floating end 31 is driven by a telescopic cylinder, the base of the telescopic cylinder is rotationally connected to the pipe front wall of the machine tool (the rotation axis is the first axis), and the telescopic end of the telescopic cylinder is rotationally connected to the floating end 31 (the rotation axis is the second axis), so that the floating end 31 can rotate around the first axis, thereby realizing lifting.

[0049] It can be understood that the floating end 31 and the fixed end 32 are provided with a swing arm, and the telescopic end is rotationally connected to the lower side wall of the swing arm (the second axis), and when the swing arm is flat, the trend is consistent with the trend of the machine tool 2.

[0050] Of course, the lifting of the floating support device 3 can be other ways, such as direct lifting by a cylinder / motor, instead of rotating lifting; when the swing arm is flat, it can also be perpendicular to the trend of the machine tool 2, but it will reduce the effective length of the feeding arm 11 to a certain extent (reduce the storage amount of the feeding arm 11 under the same space).

[0051] Based on the embodiment of the present application, when the floating support device 3 receives the pipe 6 on the feeding arm 11, the height of the floating end 31 should be lowered first, so that it is below the upper surface of the feeding arm 11, and then the height of the floating end 31 is raised to lift the pipe 6 to the cutting position when the pipe 6 reaches the projection position.

[0052] When the floating support device 3 is lowered to the lowest position (the swing arm is in a horizontal state), the floating end 31 of the floating support device 3 is below the upper surface of the feeding arm 11, and the floating end 31 is within the running range of the conveying chain 7.

[0053] When the floating support device 3 is raised, the floating end 31 will lift the pipe 6 on the conveying chain 7 upward, so that it is separated from the conveying chain 7; the lifting height can be controlled, so that the pipe 6 reaches the cutting position, and the two ends of the pipe 6 are respectively aligned with the center holes of the cutting chuck 5 and the tail end chuck 4 at the cutting position.

[0054] In the embodiment of the present application, a position sensor can be arranged at the position where the projection position is located, and the position sensor can be arranged at the discharge end of the feeding arm 11 or the machine tool 2, which can be selected according to the actual situation.

[0055] Exemplarily, a plurality of position sensors are arranged at the discharge end of each feeding arm 11, and the arrangement trend of the plurality of position sensors is consistent with the distribution trend of the plurality of floating ends 31, and when the pipe 6 is detected by the position sensor, the pipe 6 is just above the floating end 31.

[0056] In specific implementation, the in-place sensor can be selected as a photoelectric sensor, a proximity switch, etc., meanwhile, the driving structure of the feeding arm 11 and the in-place sensor are electrically connected with the control system of the machine tool 2, the driving system of the floating support device 3 is electrically connected with the control system; wherein, the control system can at least perform the following operations:

[0057] The control system stops the operation of the feeding arm 11 according to the detection data of the in-place sensor, controls the floating support device 3 to rise, and receives the pipe 6 on the projection position;

[0058] After the control system drives the floating support device 3 to rise to the cutting position, the two chucks are driven to hold the pipe 6.

[0059] After the control system drives the floating support device 3 to reset to the lowest position, the feeding arm 11 is started to transport the pipe 6 to the discharge end.
