[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] like Figure 1-11As shown, a multi-station transmission component production cutting device provided by the present invention comprises a feeding mechanism 100, a conveying assembly 200, and a cutting machine 300. The inlet end of the conveying assembly 200 is arranged on one side of the feeding mechanism 100, and the cutting machine 300 is arranged at the outlet end of the conveying assembly 200. When the device is working, the feeding mechanism 100 continuously conveys the tube blanks 400 to be cut to the inlet end of the conveying assembly 200, and the conveying assembly 200 continuously receives these tube blanks 400 and conveys them to the outlet end of the conveying assembly 200. The cutting machine 300 is provided with a turntable 310, a transfer-in mechanism 320, a cutting mechanism 330, a transfer-out mechanism 340, and a purge structure 350. The turntable 310 can rotate relative to the cutting machine 300, and the transfer-in mechanism 320, the cutting mechanism 330, the transfer-out mechanism 340, and the purge structure 350 are sequentially arranged at intervals around the circumference of the turntable 310, and can be arranged at even intervals or uneven intervals. The circumferential edge of the turntable 310 is provided with a plurality of positioning mechanisms 360 for positioning and supporting the tube blank 400, so as to prevent the tube blank 400 from deviating from or falling when the turntable 310 rotates. The number of the positioning mechanisms 360 is preferably greater than or equal to three, so as to improve the cutting efficiency. When the transfer mechanism 320 is working, first, one of the positioning mechanisms 360 is rotated to the position area where the transfer mechanism 320 is located by rotating the turntable 310. Afterwards, the transfer mechanism 320 transfers the tube blank in place at the outlet end of the conveying assembly 200 to the positioning mechanism 360. It can be understood that if the number of positioning mechanisms 360 is large, the turntable 310 can also be rotated to transfer the tube blank to the next positioning mechanism 360. Afterwards, the turntable 310 rotates the positioning mechanism 360 to the position area where the cutting mechanism 330 is located. When the cutting mechanism 330 is working, the tube blank 400 fixed on the positioning mechanism 360 is cut into a plurality of primary products 500. Finally, the turntable 310 is rotated to rotate the positioning mechanism 360 to the position area where the transfer-out mechanism 340 is located. When the transfer-out mechanism 340 is working, the primary product 500 is transferred out of the cutting machine table 300. Optionally, one primary product 500 can be transferred each time, or multiple primary products 500 can be transferred each time. Before the transfer-in mechanism 320 works, the purge structure 350 is used to blow away the debris on the turntable 310, such as the metal debris formed by the last cutting, so as to prevent these stains from contaminating the tube blank 400.

[0038] In some optional embodiments, such as Figure 3 , 4As shown, the feeding mechanism 100 includes a machine 110 and a multi-stage telescopic table assembly 120. The machine 110 is provided with a receiving chamber 111 inside, and a working chamber 112 is provided at the upper end of the machine 110. The tube blank 400 can be placed in the working chamber 112. The multi-stage telescopic table assembly 120 is arranged between the receiving chamber 111 and the working chamber 112. The bottom of the working chamber 112 is provided with an opening 1121 connected to the receiving chamber 111. A plurality of limiting plates 1122 with gradually increasing heights are provided from right to left at the opening 1121. Adjacent limiting plates 1122 are arranged in parallel at intervals. Each limiting plate 1122 is arranged obliquely relative to the bottom of the working chamber 112, and the oblique direction is toward the inlet end of the conveying assembly 200. The multi-stage telescopic table assembly 120 includes a moving frame assembly 121 and a first driving assembly 122 arranged obliquely relative to the bottom of the working chamber 112. The moving frame assembly 121 is inclined toward the inlet end of the conveying assembly 200. Specifically, the movable frame assembly 121 includes a driving plate 1211, a plurality of sliding frames 1212 arranged from right to left and gradually increasing in height, and a support plate 1213. The lower ends of all the sliding frames 1212 are fixed to the driving plate 1211. The number of sliding frames 1212 is consistent with the number of gaps between adjacent limiting plates 1122. The support plate 1213 is fixed to the upper end of the sliding frame 1212. The first driving assembly 122 is transmission-connected to the driving plate 1211. When the first driving assembly 122 is working, it drives the sliding frame 1212 to reciprocate along an inclined direction parallel to the limiting plate 1122. Since the support plate 1213 is fixed together with the sliding frame 1212, the support plate 1213 can slide in the gap between adjacent limiting plates 1122 by reasonably setting the length of the reciprocating stroke of the sliding frame 1212.

[0039] Exemplarily, there are four groups of limit plates 1122 from right to left, and four groups of support plates 1213. When the slide frame 1212 is at the lowest position, the first tube blank 400 is supported between the top of the shortest support plate 1213 on the right and the second group of limit plates 1122 from right to left. When the first group of support plates 1213 from right to left is lifted to a position flush with the second group of limit plates 1122 from right to left, the tube blank 400 rolls to the top of the second group of limit plates 1122. Then, when the slide frame 1212 is lowered to a position flush with the second group of limit plates 1122, the tube blank 400 rolls to the top of the second group of support plates 1213 from right to left, and so on, until the tube blank 400 rolls to the entrance end of the conveying assembly 200. As long as the tube blanks 400 are placed on the shortest support plates 1213 in sequence, the purpose of continuously conveying the tube blanks 400 can be achieved.

[0040] In some optional embodiments, such as Figure 3As shown, the first driving assembly 122 includes a telescopic cylinder 1221 and a mounting seat 1222. Both the telescopic cylinder 1221 and the mounting seat 1222 are located in the accommodating cavity 111, which can prevent external foreign objects from interfering with the operation of the telescopic cylinder 1221. Specifically, the mounting seat 1222 is fixed to the machine 110, the telescopic cylinder 1221 is fixed to the mounting seat 1222, and the telescopic tube at the front end of the telescopic cylinder 1221 is fixed to the driving plate 1211. In this way, when the telescopic cylinder 1221 is working, it can drive the slide frame 1212 to reciprocate along the inclined direction parallel to the limit plate 1122, so as to achieve the purpose of continuously conveying the tube blank 400.

[0041] In some optional embodiments, such as Figure 3 As shown, in order to facilitate the tube blank 400 to continuously roll onto the top of the shortest support plate 1213, a support plate 130 is arranged on the top of the limiting plate 1122 with the lowest height on the right side, and the extension direction of the support plate 130 is inclined relative to the plane where the bottom of the working chamber 112 is located, so that the tube blank 400 can roll to the top of the shortest support plate 1213 by itself under the action of gravity. Of course, the premise is that the top height of the shortest support plate 1213 on the right should not be higher than the top height of the support plate 1213.

[0042] In some optional embodiments, such as Figure 1 , 2As shown, the conveying assembly 200 includes a conveyor belt 210, a first detector 220, and a second detector 230. The inlet end of the conveyor belt 210 is located on the side of the highest limit plate 1122. The first detector 220 is arranged on the conveyor belt 210, and the position of the first detector 220 is close to the outlet end of the conveyor belt 210, for example, the distance between the first detector 220 and the end of the outlet end of the conveyor belt 210 exceeds the length of a tube 400. When the conveyor belt 210 is running, the first detector 220 can detect whether there is a tube 400 being conveyed on the conveyor belt 210. Optionally, the first detector 220 can select a Hall sensor. When the Hall sensor detects that there is no tube 400 being conveyed, the signal does not change, indicating that the feeding mechanism 100 is damaged at this time. At this time, the turntable 310, the transfer-in mechanism 320, the cutting mechanism 330, the transfer-out mechanism 340, and the purge structure 350 can be controlled not to operate. The second detector 230 is arranged on the conveyor belt 210, and the position of the second detector 230 is arranged at the end of the outlet end of the conveyor belt 210. Optionally, the second detector 230 can select a reflective laser sensor. When the conveyor belt 210 is running, the reflective laser sensor can detect whether the distance between the tube blank 400 on the conveyor belt 210 and it is within a preset range, that is, whether there is a tube blank 400 at the predetermined position of the outlet end of the conveyor belt 210. When it is detected that the tube blank 400 is within the preset range, the conveyor belt 210 can be controlled to stop rotating, and the turntable 310, the transfer mechanism 320, the cutting mechanism 330, the transfer mechanism 340, and the purge structure 350 can be controlled to perform corresponding actions respectively.

[0043] In some optional embodiments, such as Figure 5As shown, the transfer mechanism 320 includes a first column 321, a first guide rail 322, a first telescopic motor 323, and a clamping claw assembly 324. The first column 321 is fixedly connected to the cutting machine table 300, and the height of the first column 321 is greater than the height of the turntable 310, and specifically, it is also higher than the height of the positioning mechanism 360, so that the positioning mechanism 360 will not collide with the first column 321 when the turntable 310 rotates. The first guide rail 322 is fixedly connected to the first column 321, and the first telescopic motor 323 is slidably arranged on the first guide rail 322, so that the first telescopic motor 323 can slide on the first guide rail 322 as a whole, and the sliding direction of the first telescopic motor 323 is parallel to the plane where the turntable 310 is located. It is understandable that when a set of first guide rails 322 is provided, a corresponding anti-rotation structure is also required to prevent the first telescopic motor 323 from rotating relative to the first guide rails 322 during the sliding process. Preferably, multiple sets of first guide rails 322 arranged in parallel and spaced apart are provided, for example, three sets, so as to improve the sliding stability of the first telescopic motor 323. The clamping jaw assembly 324 is provided on the telescopic portion of the first telescopic motor 323. When the first telescopic motor 323 is extended and retracted, the clamping jaw assembly 324 can approach and move away from the positioning mechanism 360 on the turntable 310. In addition, two clamping jaws 3241 with adjustable spacing are provided on the clamping jaw assembly 324, so that the clamping jaws 3241 can be adjusted accordingly according to the diameter of the tube blank 400, so as to firmly grasp the outer wall of the tube blank 400.

[0044] In some optional embodiments, such as Fig.10As shown, the roll-out mechanism 340 includes a second column 341, a second guide rail 342, a second telescopic motor 343, and two third telescopic motors 344. The second column 341 is fixedly connected to the cutting machine 300, and the height of the second column 341 is greater than the height of the turntable 310, and specifically, it is also higher than the height of the positioning mechanism 360, so that the positioning mechanism 360 will not collide with the second column 341 when the turntable 310 rotates. The second telescopic motor 343 is slidably arranged on the second guide rail 342, so that the second telescopic motor 343 can slide on the second guide rail 342 as a whole, and the sliding direction of the second telescopic motor 343 is parallel to the plane where the turntable 310 is located. It can be understood that when a set of second guide rails 342 is provided, a corresponding anti-rotation structure is also required to prevent the second telescopic motor 343 from rotating relative to the second guide rail 342 during the sliding process. Preferably, multiple sets of second guide rails 342 arranged in parallel and spaced apart are provided, such as three sets, so as to improve the sliding stability of the second telescopic motor 343. In order to transfer the primary product 500 on the positioning mechanism 360 below the second telescopic motor 343, a connecting plate 3431 is provided on the telescopic rod of the second telescopic motor 343, and the two third telescopic motors 344 are fixedly connected to the connecting plate 3431, and the telescopic rods of the two third telescopic motors 344 are arranged opposite to each other. When it is necessary to transfer the primary product 500, the two third telescopic motors 344 are first in a telescopic state, at which time the telescopic rods of the two third telescopic motors 344 do not abut together, and the distance between the front ends of the two telescopic rods is greater than the thickness of the primary product 500, or when transferring multiple primary products 500 arranged side by side, the distance between the front ends of the two telescopic rods is greater than the total thickness of the multiple primary products 500, so that when the two third telescopic motors 344 are extended and retracted, the two telescopic rods are inserted into the central hollow part of the primary product 500 from both sides until the two telescopic rods abut together, and then the second telescopic motor 343 performs corresponding actions to transfer the primary product 500.

[0045] In some optional embodiments, such as Fig.11 As shown, the purge structure 350 includes a base 351 and a first purge head 352. The base 351 is fixedly connected to the cutting machine 300, and the height of the base 351 is greater than the height of the turntable 310, so that the top of the base 351 can extend toward the turntable 310. The first purge head 352 is fixedly connected to the base 351. The air inlet of the first purge head 352 is connected to an external air compressor during operation, and the air outlet of the first purge head 352 faces the turntable 310. Since the top of the base 351 is close to the turntable 310, the first purge head 352 thereon is also close to the turntable 310, so that the high-pressure gas sprayed from the air outlet of the first purge head 352 is also closer to the turntable 310, so that the debris on the turntable 310 can be quickly and effectively purged.

[0046] In some optional embodiments, such as Figure 6 , 7As shown, the positioning mechanism 360 is a fixed seat, the lower end of the fixed seat is fixed to the edge of the turntable 310, and the upper end part of the fixed seat is located outside the turntable 310, and at least one arc-shaped groove 361 is provided on this part, for example, two grooves 361 can be provided, so that each fixed seat can hold two tube blanks 400, which can improve the working efficiency. In addition, since the outer shape of the tube blank 400 is circular, when the tube blank 400 is placed in the groove 361, the tube blank 400 is not easy to rotate, and in order to prevent the tube blank 400 from axially and radially translating, the size of the groove 361 also needs to be adapted to the tube blank 400. In order to facilitate the cutting mechanism 330 to cut the tube blank 400 placed in the groove 361, a plurality of first scoring channels 3611 arranged in parallel at intervals are provided on the side wall of the groove 361.

[0047] like Figure 6-9As shown, the cutting mechanism 330 includes at least one slide bar 331, a mounting box 332, a second drive assembly 333, a plurality of saw wheels 334 arranged in parallel at intervals, a third column 335, a fourth telescopic motor 336, a press frame 337, and a third drive assembly 338. The slide bar 331 is fixed to the cutting machine table 300, and the height of the slide bar 331 is greater than the turntable 310. The mounting box 332 is slidably arranged on the slide bar 331. It can be understood that when a slide bar 331 is provided, a corresponding anti-rotation structure is also required to prevent the mounting box 332 from rotating relative to the slide bar 331 during the sliding process. Preferably, a plurality of parallel and spaced slide bars 331 are provided, for example, two, so as to improve the sliding stability of the mounting box 332. The interior of the mounting box 332 is hollow, the bottom of the mounting box 332 is open, and the second drive assembly 333 is in transmission connection with the mounting box 332, so that when the second drive assembly 333 acts, the mounting box 332 can be driven to move up and down on the slide bar 331. Optionally, the second drive assembly 333 can be a telescopic cylinder or a telescopic motor, and the telescopic cylinder or the telescopic motor can be fixedly installed on the slide bar 331 during specific assembly. The third drive assembly 338 is connected to the saw wheel 334 in a transmission manner. When the third drive assembly 338 is working, the saw wheel 334 is driven to rotate, and the saw wheel 334 rotates at a high speed to cut the tube 400. Optionally, the third drive assembly 338 can be a rotary motor, and when the rotary motor is in a specific assembly, the rotary motor is fixedly installed on the installation box 332, and the rotating shaft of the rotary motor can be connected to the saw wheel 334 through a speed reducer to provide a large torque to drive the saw wheel 334 to rotate. Part of the saw wheel 334 is located in the installation box 332, and the saw wheel 334 is rotatably arranged on the inner wall of the installation box 332. By arranging part of the saw wheel 334 in the installation box 332, on the one hand, it can prevent the metal debris generated when cutting the tube 400 from splashing in a large range, and on the other hand, it can prevent the saw wheel 334 from splashing when it breaks and causing safety accidents or damaging other devices and equipment. In order to avoid positioning problems of the saw wheel 334 , the number of the first marking lanes 3611 is greater than or equal to the number of the saw wheel 334 .

[0048] like Figure 6 , 8As shown, the third column 335 is fixed to the cutting machine 300, and the height of the third column 335 is less than the height of the turntable 310. The fourth telescopic motor 336 is fixed to the third column 335, and the pressing frame 337 is fixed to the telescopic rod of the fourth telescopic motor 336. When the fourth telescopic motor 336 is working, it can drive the pressing frame 337 to move up and down. The top height of the pressing frame 337 is greater than the turntable 310. Specifically, the height of the third column 335 is higher than the height of the positioning mechanism 360, so that the positioning mechanism 360 will not collide with the third column 335 when the turntable 310 rotates. Before cutting the tube blank 400, the fourth telescopic motor 336 drives the pressing frame 337 to move downward until the top of the pressing frame 337 presses against the top of the tube blank 400. In this way, under the common limiting action of the groove 361 and the pressing frame 337, the tube blank 400 can be stably placed in the groove 361, which is conducive to the cutting of the saw wheel 334. Since the pressing frame 337 presses against the tube 400 and blocks the saw wheel 334, a plurality of second scoring paths 3371 are arranged in parallel at intervals on the pressing frame 337. The second scoring paths 3371 are arranged through, and the saw wheel 334 extends to the tube 400 through the second scoring paths 3371, thereby realizing the cutting function. At the same time, the existence of the pressing frame 337 can prevent the splashing of metal debris generated by cutting to a certain extent.

[0049] In some optional embodiments, such as Figure 6 As shown, a second purge head 3321 is provided on the outer wall of the installation box 332. When the second purge head 3321 is in use, its air inlet is connected to an external air compressor, and the air outlet of the second purge head 3321 is toward the positioning mechanism 360 below the saw wheel 334. In this way, when the saw wheel 334 is cutting, the high-speed cold air flow can reduce the large amount of heat generated by the high-speed rotation of the saw wheel 334 and the friction of the tube blank 400, so as to prevent the high temperature from causing the saw wheel 334 to deform or reduce the structural strength. In addition, it can also prevent the splashing energy of metal debris generated when cutting the tube blank 400, thereby reducing the range of metal debris splashing.
