Description

Technical Field

[0001] The invention belongs to the technical field of tube cutting machines, and in particular relates to a semi-automatic feeding device of a light laser tube cutting machine. Background Art

[0002] The working logic of the traditional semi-automatic feeder is: manually place the pipes in order on the conveyor chain so that the pipes are conveyed forward in a uniform posture (to prevent some rectangular pipes from facing down with their wide sides and others with their narrow sides, and to prevent square pipes and rectangular pipes from being stacked together and conveyed forward). When the pipe is conveyed to the bottom of the chuck, the chain stops when the chain sensor senses the pipe. After the pipe is conveyed to the right place, the floating support lifting cylinder lifts the pipe, and the floating support centering clamp module clamps the pipe and lifts it to the center of the chuck. When this traditional semi-automatic feeder is in use, the pipe needs to wait outside the chuck; after the chuck returns to zero, the conveyor chain moves forward to convey the pipe to the bottom of the chuck, and then the floating support rises. The feeding cycle of each pipe is long and the efficiency is low. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0022] The embodiment of the present invention provides a semi-automatic feeding device for a light laser tube cutting machine. Figure 1 , Figure 2, Figure 3 , Figure 4 , mainly including a loading module 1 docked to one side of the machine tool 2, the loading module 1 includes a plurality of feeding arms 11 and a reference arm arranged in parallel and perpendicular to the direction of the machine tool 2, the reference arm is vertically arranged on the rear side of the cutting chuck 5 of the machine tool 2, and the plurality of feeding arms 11 are sequentially and spaced apart between the reference arm and the tail end chuck 4 of the machine tool 2; the feeding arm 11 is equipped with a circulating conveying chain 7, and the conveying chain 7 is equipped with a plurality of equally spaced limit blocks 8 for limiting the position of the pipe 6, the conveying chains 7 on the plurality of feeding arms 11 run synchronously, and the positions of the limit blocks 8 carried on the conveying chains 7 are the same, so that when the plurality of conveying chains 7 run synchronously, two adjacent limit blocks 8 located on the upper surface of the plurality of feeding arms 11 and in the same position jointly limit and convey a pipe 6.

[0023] In the present application, the loading module 1 is a conveying structure for the pipe 6, which conveys the pipe 6 to a specific position. At the specific position, the pipe 6 is received by the floating support device 3 carried by the machine tool 2, and the pipe 6 is lifted upward to the cutting position, that is, docked with the cutting chuck 5 and the tail end chuck 4.

[0024] It can be understood that the position of the floating support device 3 is fixed and is located directly below the cutting position. The above-mentioned specific position (hereinafter referred to as the projection position) can be obtained by projecting the cutting position onto the feeding arm 11. When it is detected that the pipe 6 is transported to the projection position, the transportation can be stopped and the floating support device 3 will lift the pipe 6 upward to the cutting position.

[0025] At the cutting position, the two ends of the tube 6 are aligned with the center holes of the cutting chuck 5 and the tail end chuck 4 respectively, so that the cutting chuck 5 and the tail end chuck 4 can clamp the tube 6, thus completing the loading of the tube 6; subsequently, the cutting process can be carried out.

[0026] In the embodiment of the present application, the feeding module 1 should be located between the cutting chuck 5 and the tail chuck 4, so that the tube 6 is located between the two chucks for easy clamping. In the traditional feeding device, the feeding device is directly connected to the machine tool 2, and the relative position between the conveying position of the tube 6 and the chuck is uncertain, which can easily lead to the chucks at both ends holding the tube 6 incorrectly or failing to hold the tube 6.

[0027] Based on this, the loading module 1 of the present application is positioned and installed based on a chuck on the machine tool 2, so that the relative position relationship between at least one end of the tube 6 and the chuck is relatively clear, so that the chucks at both ends can synchronously complete the support of the tube 6.

[0028] In a specific embodiment, in order to better serve the processing operations after clamping and shorten the loading cycle, the cutting chuck 5 can be selected as the reference, and a reference arm is set on the machine tool 2. Multiple feeding arms 11 are distributed in sequence between the reference arm and the tail chuck 4, which can be evenly spaced or unevenly distributed.

[0029] The cutting chuck 5 is closer to the front end of the tube 6, while the tail end chuck 4 is farther from the rear end of the tube 6. When clamping, the running speed and running distance of the tail end chuck 4 can be adjusted according to the length of the tube 6, so that the two chucks can stably and quickly clamp the tube 6.

[0030] Specifically, the reference arm is not equipped with a driving structure, while the feeding arm 11 is equipped with a corresponding driving structure for driving the circulating operation of the conveying chain 7 .

[0031] Exemplarily, the reference arm only includes a support structure, on which a vertical reference plate 12 parallel to the feeding arm 11 can be mounted, the front end of the pipe 6 between two adjacent limit blocks 8 is close to the reference plate 12, and the front end surface of the pipe 6 is parallel to the side surface of the reference plate 12. Specifically, the support structure may include a crossbeam, a support foot, etc., and the reference plate 12 is arranged on the crossbeam, such as Figure 2 as shown in .

[0032] When manually placing the material, the front end of the pipe 6 can be placed close to the reference plate 12, so that the relative position relationship between the pipe 6 and the cutting chuck 5 is clearer, which is convenient for clamping. 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, which is convenient for alignment during manual placing.

[0033] Exemplarily, the feeding arm 11 may include a supporting structure and a driving structure, wherein the driving structure is used to drive the conveying chain 7 to circulate, and the supporting structure is used to support the driving structure and the conveying chain 7. Specifically, the driving structure may include a driving motor, a gear, etc., and the supporting structure may include a housing, a supporting foot, etc., as shown in FIG. Figure 3 as shown in .

[0034] Specifically, the conveying chain 7 includes a driving chain 71 and limit blocks 8 , and the limit blocks 8 are fixed at equal intervals on the outer ring side of the driving chain 71 .

[0035] In a specific embodiment, a right support member 72 and a left support member 73 are respectively provided on both sides of the drive chain 71, and the limit block 8 includes multiple limit members, the left side of the limit member is fixed to the left support member 73, and the right side of the limit member is fixed to the right support member 72. The length of a single limit member is the same as the length of a single chain structure of the drive chain 71, and multiple limit members are continuously fixed on the drive chain 71 to form a limit block 8.

[0036] Exemplarily, the left and right support members can be symmetrical structures, such as right-angle plates, with the right angles facing outward, the vertical plate has two holes for fixing with a single chain structure, and the horizontal plate is located on the upper side (outside) for fixing with a single stopper. The single stopper can be a square tube structure with an opening on the bottom wall, and the opening on the bottom wall is opened along the axial direction to form two symmetrical hanging plates, and the two hanging plates can be fixed to the horizontal plates of the two support members respectively.

[0037] In an embodiment of the present application, the conveying chain 7 is equipped with a plurality of equally spaced limit blocks 8 for limiting the position of the pipe 6. The conveying chains 7 on the plurality of feeding arms 11 run synchronously, and the positions of the limit blocks 8 carried on the conveying chains 7 are the same, so that when the plurality of conveying chains 7 run synchronously, two adjacent limit blocks 8 located on the upper surface of the plurality of feeding arms 11 and in the same position jointly limit the conveyance of a pipe 6.

[0038] Multiple feeding arms 11 should operate synchronously so that the running step distance of the conveying chain 7 carried on each feeding arm 11 is consistent. At the same time, the length of each conveying chain 7 should be consistent, and the intervals of the limit blocks 8 should also be consistent. After the conveying chain 7 is assembled on the gear, the position of the limit blocks 8 on each feeding arm 11 is the same, so as to achieve synchronous conveying of the pipe 6.

[0039] Each feeding arm 11 only positions the pipe 6 through the limit blocks 8 on the upper surface. Only one pipe 6 is placed between two adjacent limit blocks 8. After the pipe 6 is positioned by the limit blocks 8 on the feeding arms 11, its direction is parallel to the direction of the machine tool 2. Figure 2 as shown in .

[0040] Among them, there should be multiple limit blocks 8 on the upper surface of the feeding arm 11 at the same time, with multiple positions that can clamp the pipe 6, so that the loading module 1 can transport multiple pipes 6 at the same time, and the multiple pipes 6 are partitioned and blocked by the limit blocks 8, and there will be no confusion, crossing and the like; at the same time, material storage is realized on the feeding arm 11, even if the manual discharge speed at the feeding end is slow, the efficiency stability of the discharging end can also be guaranteed. For example, the intermittent delivery of the pipe 6 to the floating support device 3 at the discharging end will not have a significant impact on the loading cycle. Compared with the conventional semi-automatic loading device, it still has great advantages and reduces the loading cycle.

[0041] In an embodiment of the present application, one side of the machine tool 2 (the side where the chuck is installed) is equipped with multiple floating support devices 3 along the direction of the machine tool 2. The multiple floating support devices 3 can be installed on a frame below the machine tool 2, and the discharge ends of the feeding arms 11 are all located above the frame; the multiple floating support devices 3 and the multiple feeding arms 11 can be distributed alternately, and the discharge 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.

[0042] Exemplarily, the lower end surface of the fixed end 32 of the floating support device 3 is fixed to the top surface of the pipe of the frame, and the floating end 31 can be driven by a telescopic cylinder. The base of the telescopic cylinder is rotatably connected to the front wall of the pipe of the frame (the rotating axis is the first axis), and the telescopic end of the telescopic cylinder is rotatably connected to the floating end 31 (the rotating axis is the second axis), so that the floating end 31 can rotate around the first axis, thereby realizing lifting and lowering.

[0043] It can be understood that a swing arm is provided between the floating end 31 and the fixed end 32 , and the telescopic end can be rotatably connected to the lower side wall of the swing arm (second axis). When the swing arm is laid flat, its direction is consistent with the direction of the machine tool 2 .

[0044] Of course, the floating support device 3 can be lifted and lowered in other ways, such as directly lifted and lowered by a cylinder / motor instead of rotating and lifting; when the swing arm is flat, it can also be perpendicular to the direction of the machine tool 2, but it will reduce the effective length of the feeding arm 11 to a certain extent (reducing the storage capacity of the feeding arm 11 in the same space).

[0045] 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. When the pipe 6 reaches the projection position, the height of the floating end 31 should be raised to lift the pipe 6 to the cutting position.

[0046] When the floating support device 3 descends to the lowest position (the swing arm is in a horizontal state), the floating end 31 of the floating support device 3 is located below the upper surface of the feeding arm 11 , and the floating end 31 is located within the operating range of the conveying chain 7 .

[0047] When the floating support device 3 rises, the floating end 31 lifts the pipe 6 on the conveying chain 7 upward to separate it from the conveying chain 7; the rising height can be controlled so that the pipe 6 reaches the cutting position. At the cutting position, 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.

[0048] In the embodiment of the present application, an in-place sensor may be provided at the location of the projection position, and the in-place sensor may be provided at the discharge end of the feeding arm 11, or on the frame of the machine tool 2, which may be selected according to actual conditions.

[0049] Exemplarily, multiple in-place sensors are arranged at the discharge end of each feeding arm 11 , and the arrangement direction of the multiple in-place sensors is consistent with the distribution direction of the multiple floating ends 31 . When the in-place sensors detect the pipe 6 , the pipe 6 is just located above the floating end 31 .

[0050] In specific implementation, the in-position sensor can be a photoelectric sensor, a proximity switch, etc. At the same time, the driving structure of the feeding arm 11 and the in-position sensor are electrically connected to the control system of the machine tool 2, and the driving system of the floating support device 3 is electrically connected to the control system; wherein the control system can at least perform the following operations: The control system stops the operation of the feeding arm 11 according to the detection data of the in-position sensor, controls the floating support device 3 to rise, and receives the pipe 6 at the projection position; After the control system drives the floating support device 3 to rise to the cutting position, it drives the two chucks to hold the pipe 6; After the control system drives the floating support device 3 to return to the lowest position, the feeding arm 11 is started to convey the pipe 6 to the discharge end.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device comprising the elements.

[0052] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes, and it cannot be determined that the specific embodiments of the present invention are limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
