DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] like Figure 1The carbon fiber square tube 1' shown is a hollow square tube body 11' as a whole (of course, the cross section of the carbon fiber square tube 1' can also be a structure that can be extruded by any other molding mold, such as a circular ring, etc.), and its at least one end surface is processed into a regular notch 12' (it can be one end or both ends); at the same time, the square tube body 11' is provided with a through hole 13' corresponding to the position of the notch 12' and a through groove 14' extending outward from the notch 12' to the end face of the square tube body 11'. Two convex strips 15' corresponding to the through groove 14' can also be formed on the inner wall of the carbon fiber square tube 1' as needed. These two convex strips 15' are usually formed integrally with the square tube body 11' when the carbon fiber square tube 1' is extruded.

[0019] The above-mentioned efficient processing method of the carbon fiber square tube 1' comprises the following steps: A plurality of carbon fiber square tubes 1' (the specific number can be conventionally selected according to actual needs, but the total width thereof is smaller than the single side length of the diamond cutting wire 230) are processed simultaneously by using a diamond cutting wire 230 to form a notch 12' on each carbon fiber square tube 1'; preferably, the cross section of the notch 12' is also engraved and finished; The notch 12' is cut outward to form a through groove 14' extending to the end surface of the square tube 11'; preferably, the cross section of the through groove 14' is also finely processed; Then, a hole is punched on the square tube body 11' to form a through hole 13' corresponding to the position of the notch 12'; then, the carbon fiber square tube 1' is sequentially subjected to sandblasting, cleaning and drying.

[0020] The following steps are also included before processing: Arrange a plurality of carbon fiber square tubes 1' neatly on a stacking rack 1 and divide them into at least one layer; The carbon fiber square tube 1 ′ is transferred layer by layer to the single-head wire saw 2 .

[0021] The above-mentioned efficient processing method of carbon fiber square tube 1' is based on Figure 2 The high-efficiency processing equipment of carbon fiber square tube shown in the figure. The high-efficiency processing equipment at least includes a single-head wire cutting machine 2, and it usually also includes a plurality of stacking racks 1 arranged at one side of the single-head wire cutting machine 2 and arranged at intervals (the stacking racks 1 have at least two groups, which are used for loading and unloading respectively. In this embodiment, there are three groups, one group is a loading group, another group is a unloading group, and the third group is a buffer group; usually the loading group and the third group are not fixed but are dynamically and cyclically adjusted according to the presence or absence of materials; in Figure 2In the embodiment, the left group is a loading group, the middle group is empty, and the right group is a unloading group), a drying and cleaning assembly 8 (used for cleaning and drying the product surface) is arranged on one side of the stacking rack 1, a sandblasting machine 7 (used for surface grinding, and the existing conventional one can be used) is arranged on one side of the drying and cleaning assembly 8, a punching machine 6 (used for punching to form a through hole 13', and the existing conventional one can be used) is arranged on one side of the sandblasting machine 7, a machining center 5 (used for fine machining of the cross section of the through groove 14') is arranged on one side of the punching machine 6, a water jet cutting machine 4 (cutting to form the through groove 14') is arranged on one side of the machining center 5, and a multi-head engraving machine 3 (used for engraving and fine machining of the cross section of the notch 12'; when there are other engraving structures on the surface of the square tube body 11', the multi-head engraving machine 3 can also be used for processing) is arranged on one side of the water jet cutting machine 4 and on one side of the single-head wire cutting machine 2, so that the carbon fiber square tube 1' is transferred and processed in the order of increasing the reference numerals. The transfer can be achieved manually, but it is more preferably achieved by a multi-axis robot 0 assisted by a corresponding fixture to improve efficiency, so that one layer on the stacking rack 1 can be transferred at a time. Specifically, a corresponding multi-axis robot 0 is installed between two adjacent devices to achieve the transfer of one layer of the stacking rack 1 between two adjacent devices; the operator 0' stands on one side of the stacking rack 1 to place the carbon fiber square tubes 1' one by one on the middle stacking rack 1 to form a neat layer or layers; after all the materials on the left stacking rack 1 are transferred, the operator 0' adjusts the positions of the left stacking rack 1 and the middle stacking rack 1 to continue loading; after the right stacking rack 1 is filled with processed materials, it can be replaced with an empty one. The above operation can be achieved by one person alone after controlling the beat, or it can be achieved by two people (one loading and one unloading) while ensuring efficiency.

[0022] like Figures 3 to 6 The stacking rack 1 shown mainly includes a supporting frame 11 and a stacking assembly 12 and other structures that match each other.

[0023] The support frame 11 includes a plurality of first support vertical rods 111 arranged around the stacking assembly 12 (in the present embodiment, there are four first support vertical rods 111, which are arranged on the outside of the four corners of the stacking assembly 12), a plurality of first support cross rods 112 connecting the tops of two adjacent first support vertical rods 111 (in the present embodiment, there are also four first support cross rods 112, which are respectively connected to the two adjacent first support vertical rods 111 by a conventional connection method, so that the four first support cross rods 112 form a frame structure; the conventional connection method can be welding fixation, or it can be detachably connected by fasteners such as bolts and screws, the same below), and a plurality of second support cross rods 113 (second support cross rods 114) connecting the middle parts of two adjacent first support vertical rods 111 and located below the first support cross rod 112. There are also four 113s, which are also connected to two adjacent first support vertical rods 111 by conventional connection methods, so that the four second support cross rods 113 form a square structure; in order to lower the center of gravity of the support frame 11, the second support cross rods 113 can be formed near the lower end of the first support vertical rods 111) and a support base plate 115 installed on at least two second support cross rods 113 (in this embodiment, the support base plate 115 can be installed on two oppositely arranged second support cross rods 113 by conventional connection methods), so that the stacking assembly 12 can be placed on the support base plate 115, so that the support base plate 115 is used to support the stacking assembly 12 and the stacking assembly 12 is limited by the structure surrounded by the first support cross rods 112 and the structure surrounded by the second support cross rods 113.

[0024] In this embodiment, a plurality of third support cross bars 114 are connected between two opposite second support cross bars 113, and the specific number of the third support cross bars 114 can be conventionally selected according to actual needs, so as to better support the support bottom plate 115 and improve the bearing capacity of the stacking assembly 12. A plurality of second support vertical bars 116 are connected between the opposite first support cross bars 112 and the second support cross bars 113, and the specific number of the second support vertical bars 116 can also be conventionally selected according to actual needs, so as to better limit the four sides of the stacking assembly 12.

[0025] The stacking assembly 12 includes one or more layers of stackable loading units 121. The specific number of layers can be conventionally selected according to actual needs, but it is preferably multiple layers to improve the load-bearing efficiency. The loading unit 121 includes a support frame 1210 (the support frame 1210 can be made of basic structural elements such as strips and plates by conventional welding, integral molding, etc.), a support plate 1211 formed on any end surface of the support frame 1210 (the formation method can be conventional welding, integral molding, etc., the same below), a clamping protrusion 1212 formed at the four corners of the outer surface of the support plate 1211, and a pad 1213 formed at the edge of the outer surface of the support plate 1211 and located between two adjacent clamping protrusions 1212 (in this case, there are only two pads 1213, When the shape formed by the four clamping protrusions 1212 is a rectangle, the pad 1213 extends in parallel along the long side direction of the rectangle; that is, the extension direction of the pad 1213 is parallel to the extension direction of the long side of the outer surface of the support plate 1211, so that the pad 1213 is used to carry the carbon fiber square tube 1') and the clamping holes formed at the four corners of the support frame 1210 (inside the four corners) to match the clamping protrusions 1212 (the specific structure of the clamping hole is not limited, as long as it can be plugged and matched with the clamping protrusions 1212, such as welding and fixing the angle plates at the four corners of the support frame 1210). In this way, carbon fiber square tubes of a certain specification can be neatly arranged on the pad 1213 and the clamping protrusions 1212 can be used to limit the carbon fiber square tubes, so that multiple carbon fiber square tubes can be neatly arranged in a single layer.

[0026] In this embodiment, an inwardly recessed hole 1214 is provided in the snap-fitting protrusion 1212 (the recessed hole 1214 is communicated with the snap-fitting hole). At this time, the cross-sectional area (horizontal cross-section) of the snap-fitting hole is larger than the cross-sectional area of ​​the recessed hole 1214, so that a step portion 1215 is formed between the snap-fitting hole and the recessed hole 1214, so that the step portion 1215 is used to support the snap-fitting protrusion 1212 of the lower loading unit 121, so that the two adjacent loading units 121 can be neatly stacked and the upper loading unit 121 can be easily removed from the lower loading unit 121, which greatly facilitates the cooperation with the robot for subsequent automated operations.

[0027] like Figure 7 and Figure 8 The single-head wire cutting machine 2 shown mainly includes a supporting base 21, a material loading assembly 22, a cutting assembly 23 and other structures that cooperate with each other.

[0028] The support base 21 can adopt an existing conventional structure as long as it can support the material loading assembly 22 and the cutting assembly 23. In this embodiment, it includes a container body, a plurality of support legs installed on the bottom of the container body (at least three, but preferably seven, three are installed on each of the two long sides of the bottom of the container body and one is installed at the center of the bottom of the container body), a plurality of reinforcing columns installed in the container body and parallel to each other (preferably 2 to 5 are installed on each of the upper and lower parts of the container body), and a waste collection box arranged in the container body.

[0029] The material carrier assembly 22 includes a carrier plate 223 slidably mounted on the support base 21 and a carrier 224 mounted on the carrier plate 223 for placing a plurality of carbon fiber tubes, so that the carrier 224 carrying the carbon fiber tubes can be placed on the carrier plate 223 and limited by manual or robot methods, and the carrier plate 223 can be moved to a processing position for its advancement. In this embodiment, the material carrier assembly 22 also includes a plurality of pad tubes 221 (usually two) mounted on the support base 21 and arranged in parallel, a carrier slide rail 222 mounted on the pad tube 221 in a one-to-one correspondence, and a slider mounted on the bottom surface of the carrier plate 223 and matched with the carrier slide rail 222, a support seat 220 mounted on the support base 21, a carrier drive screw 225 mounted on the support seat 220 and connected to the carrier plate 223 through an adapter plate (the carrier drive screw 225 penetrates the adapter plate and is threadedly connected thereto), and a carrier drive motor mounted at the end of the carrier drive screw 225 for driving it to rotate. In this way, when the carrier driving motor is working, it can drive the carrier driving screw 225 to rotate synchronously, and then drive the carrier 223 to move horizontally relative to the carrier slide rail 222, thereby greatly adjusting the position of the carrier 224, so that it moves back and forth between the loading position and the processing position.

[0030] In this embodiment, the carrier assembly 22 also includes a plurality of carrier pads 2231 formed on the upper surface of the carrier plate 223 and arranged in parallel (the number of carrier pads 2231 is usually 2 to 6, which are located below the carrier 224 but are usually close to the edge of the carrier 224; the formation method may be conventional, such as installation by fasteners such as bolts, etc.), a carrier fixed block 2232 arranged on the upper surface of the carrier plate 223 and extending in a direction perpendicular to the gantry 231, and a first carrier movable block 2233, a second carrier movable block 2234 and a third carrier movable block 2235 which are adjustably installed on the upper surface of the carrier plate 223 and cooperate with the other three side surfaces of the carrier 224. The adjustable manner of the first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235 is basically the same, that is, a certain number of cylinders are installed on the upper surface of the carrier plate 223, so that the cylinders are connected to the corresponding first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235, respectively, so as to drive the first carrier moving block 2233, the second carrier moving block 2234 or the third carrier moving block 2235 to move (the difference is that the first carrier moving block 2233 and the third carrier moving block 2235 are driven by two cylinders, and the second carrier moving block 2234 is two pieces, each free from one cylinder). The carrier 224 is driven by a cylinder; the carrier fixed block 2232, the first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235 need to be arranged around the carrier 224. When their corresponding cylinders are working, the carrier fixed block 2232, the first carrier moving block 2233, the second carrier moving block 2234 and the third carrier moving block 2235 can be pressed against the four surfaces of the carrier 224, thereby clamping the carrier 224 for subsequent wire cutting (after the wire cutting process is completed, the corresponding cylinder is reset, and the carrier 224 is removed and replaced with another carrier 224 (carrying multiple carbon fiber tubes to be processed)). The carrier 224 is formed by clamping a plurality of carrier units on the left and right or fixing a plurality of carrier units on the left and right (such as welding or integrally formed), and each carrier unit is in the shape of a long strip similar to a carbon fiber square tube as a whole, and its lower part is hollow to reduce weight, and an installation groove that matches the carbon fiber square tube to accommodate the carbon fiber square tube is opened on the upper part (the inner wall of the installation groove is provided with extrusion strips extending in opposite directions), and the front and rear ends form step portions with different structures (through holes and grooves are opened on the step portions), so that it can also be used in subsequent steps and tightly clamp the carbon fiber square tube.

[0031] Cutting assembly 23, such as Fig. 9 and Fig.10As shown, it includes a gantry 231 slidably mounted on a support base 21 and spanning a loading assembly 22, a side loading plate 235 slidably mounted on the side of the gantry 231 and corresponding to the loading assembly 22, at least one driven wheel 237 mounted on the side loading plate 235, a driving wheel 238 mounted on the side loading plate 235, a tension adjusting wheel 239 mounted on the side loading plate 235 and cooperating with the driven wheel 237 and the driving wheel 238, and a diamond cutting wire 230 wound around the driving wheel 238, the driven wheel 237 and the tension adjusting wheel 239. In this embodiment, the sliding manner of the gantry 231 on the support base 21 can adopt the existing conventional method (not shown in the figure), as long as the gantry 231 can slide on the support base 21; such as installing a slide rail on the support base 21, installing a slider matching the slide rail on the gantry 231, providing a reinforcement plate on the support base 21, and installing a hydraulic cylinder connected to the gantry 231 on the reinforcement plate.

[0032] In this embodiment, a waist-shaped hole 2351 is provided on the side carrier plate 235, and a tension adjustment wheel 239 is adjustably installed in the waist-shaped hole 2351. An adjustment cylinder 2352 connected to the tension adjustment wheel 239 for driving the tension adjustment wheel 239 is installed on the side carrier plate 235. When the adjustment cylinder 2352 is working, the tension adjustment wheel 239 can be driven to move in the waist-shaped hole 2351, thereby adjusting the tension of the diamond cutting wire 230. A driving wheel driving motor 2381 connected to the driving wheel 238 through a transmission belt (not shown in the figure) is also installed on the side carrier plate 235 (the driving wheel driving motor 2381 and the driving wheel 238 are usually located on both sides of the side carrier plate 235). When the driving wheel driving motor 2381 is working, it can drive the driving wheel 238 to rotate, thereby driving the diamond cutting wire 230 to rotate in a circular manner. There are two driven wheels 237, which are located at the two corners of the lower part of the side carrier plate 235; the driving wheel 238 and the tension adjustment wheel 239 are located at the two corners of the upper part of the side carrier plate 235, so that the length of the diamond cutting wire 230 wound on them can be increased as much as possible, which can not only perform wire cutting on multiple carbon fiber tubes at the same time, but also increase the length of the diamond cutting wire, thereby extending its service life.

[0033] In this embodiment, the cutting assembly 23 further includes a shielding cover 236 mounted on the side carrier plate 235 and located outside the driving wheel 238 , the driven wheel 237 and the tension adjustment wheel 239 , and the lower part of the shielding cover 236 is open.

When the wire cutting is completed, the rodless cylinder 2313 works to drive the shifting block 2315 to move linearly along the guide rod 2310, thereby shifting the cut waste to one side to fall into the aforementioned waste collection box. The cutting assembly 23 also includes a cutting fluid nozzle 2300 and an air blow pipe 2301 extending to cooperate with the diamond cutting wire 230 to cool the diamond cutting wire 230 and avoid generating cutting dust.

[0035] In this embodiment, the cutting assembly 23 also includes a transfer pad column 232 installed on the side of the gantry 231, a side carrier slide rail 233 installed on the transfer pad column 232, and a side carrier slider 234 installed on the side carrier 235 and matched with the side carrier slide rail 233. The driving method here is the same as that of the carrier 223, which is also a combination of a screw and a motor. The installation position is not limited as long as it can drive the side carrier 235 to rise and fall relative to the transfer pad column 232. It can be seen that the diamond cutting wire 230 is used to process the square tube bodies 11' of multiple carbon fiber square tubes 1' at the same time to form a notch 12' on at least one end of each carbon fiber square tube 1'.

[0036] like Figures 11 to 13 The multi-head engraving machine 3 shown mainly includes a matching engraving base 31, a gantry assembly 32, a gantry transmission assembly 33 and an engraving assembly 34, etc., which are used to perform engraving and finishing on the cross section of the notch 12' (the portion extending in the length direction of the square tube 11') to ensure that the cross section of this portion is smooth and flat.

[0037] Among them, the carving base 31 is mainly used to support structures such as the gantry assembly 32, the gantry transmission assembly 33 and the carving assembly 34, including a bottom support frame 311 arranged on the ground, a carving carrier plate 312 installed on the bottom support frame 311 (that is, the carving carrier plate 312 is installed on the top of the bottom support frame 311) and an extended folded plate 313 installed on the side of the bottom support frame 311 and extending to the outside of the carving carrier plate 312. The carving carrier plate 312 is formed with (that is, opened with) a plurality of first mounting grooves 3121 that are parallel to each other and spaced apart (at this time, the extension direction of the extended folded plate 313 is perpendicular to the extension direction of the first mounting groove 3121). In this way, multiple carbon fiber square tubes can be installed side by side on the carving carrier plate 312 by cooperating with the multiple first mounting grooves 3121 through a plurality of conventional fasteners such as a plurality of bolt pairs.

[0039] In this embodiment, the engraving assembly 34 also includes a plurality of vertical slide rails 343 (usually two) installed on the surface of the vertical base plate 341 and spaced apart, a plurality of groups of vertical sliders 344 installed on the vertical transfer plate 345 and matched with the vertical slide rails 343 (a group of vertical sliders 344 has at least one vertical slider 344, but preferably two; the same below), a ball screw pair 342 connected to the vertical transfer plate 345, and a first stepper motor 340 installed at the end of the ball screw pair 342 (the ball screw pair 342 and the first stepper motor 340 form a ball screw module). In this way, when the first stepper motor 340 is working, it can drive the ball screw pair 342 to rotate, and then drive the vertical transfer plate 345 to perform lifting and lowering actions on the vertical slide rail 343 through the vertical slider 344. The engraving assembly 34 further includes a plurality of first slide rail pads 3411 installed on the surface of the vertical base plate 341 and arranged at intervals, and an engraving head carrier plate 347 installed on the horizontal base plate 346. The vertical slide rails 343 are installed on the first slide rail pads 3411 in a one-to-one correspondence, and each engraving head 349 is installed on the engraving head carrier plate 347 through an engraving head fixing seat 348. The installation spacing of the engraving head fixing seat 348 on the engraving head carrier plate 347 can be adjusted to adjust the spacing between the engraving heads 349 to be suitable for carbon fiber square tubes of different sizes, so that the engraving heads 349 and the corresponding carbon fiber square tube sections can be machined.

The gantry assembly 32 includes a gantry side support plate 321 connected to a transverse slider 333, a gantry top beam 322 installed on the gantry side support plate 321, a plurality of gantry transverse slide rails 323 installed on the side of the gantry top beam 322 and arranged at intervals, and a second rack 325 installed on the top surface of the gantry top beam 322 and provided with a second serration 3251. At this time, the transmission carrier plate 334 is installed on the gantry side support plate 321. In this embodiment, the gantry assembly 32 also includes a plurality of gantry sliders 324 slidably mounted on the gantry horizontal slide rail 323, a gantry upper loading plate 326 mounted on the engraving assembly 34 and extending horizontally (the gantry upper loading plate 326 is connected to the vertical base plate 341 in a conventional manner and is perpendicular to each other), a second driving wheel 328 rotatably mounted on the gantry upper loading plate 326, an engraving assembly moving motor 327 mounted on the gantry upper loading plate 326 and connected to the second driving wheel 328 via a second transmission belt, and a second transmission bevel gear 329 connected to the second driving wheel 328 and meshing with the second rack 325.

[0041] Thus, when the gantry moving motor 335 is working, the gantry assembly 32 can be driven to move on the horizontal slide rail 332; when the engraving assembly moving motor 327 is working, the engraving assembly 34 can be driven to move on the gantry horizontal slide rail 323; so as to ensure that the engraving head 349 accurately moves to the part of the product to be processed. Through the cooperation of the above structures, the multi-head engraving machine of the above structure also has the advantages of high precision and good reliability.

[0043] Among them, the water cutting support assembly 41 includes a water cutting support base 411 (the upper surface of the water cutting support base 411 is an operating table, and the product to be processed can be fixed on the operating table by existing conventional fasteners, etc.), a water cutting slide mechanism 413 installed on both side surfaces of the water cutting support base 411 (the water cutting slide mechanism 413 has two groups) and a water cutting gantry 414 slidably installed on the water cutting slide mechanism 413; the sliding method is not the invention point of the present application, as long as the relative sliding of the water cutting slide mechanism 413 and the water cutting gantry 414 can be achieved. In this embodiment, the sliding method can adopt the existing conventional method (for example, a screw is installed in each set of waterjet slide rail mechanism 413 through a conventional mounting seat, and a screw drive motor for driving the screw to rotate is installed at the end of the screw (a motor seat can also be used for auxiliary installation; a screw sleeve that can move back and forth is provided on the screw, and the screw sleeve is connected to the waterjet gantry 414 through an adapter block or the screw sleeve is directly connected to the protruding structure of the waterjet gantry 414, not shown in the figure).

[0044] In this embodiment, the waterjet support assembly 41 also includes an extended limit baffle 412 formed on both sides of the upper surface of the waterjet support base 411 (formed in the conventional manner, such as integral molding or welding, etc., the same below), which can be used to prevent the splashing of processing debris. The waterjet slide rail mechanism 413 includes an epitaxial plate 4131 formed on both sides of the waterjet support base 411 (when the multi-head waterjet machine 4 is placed on the ground, the epitaxial plate 4131 is also close to the ground), two groups of waterjet support frames 4132 installed on both sides of the waterjet support base 411 and supported on the epitaxial plate 4131 (each group of waterjet support frames 4132 includes a plurality of waterjet support frames 4132, the specific number of which can be conventionally selected according to actual needs, preferably 3 to 5), and a sliding base 4133 installed on each group of waterjet support frames 4132 (a avoidance groove matching the protruding structure of the aforementioned adapter block or waterjet gantry 414 can be provided on the sliding base 4133 to ensure the normal sliding of the corresponding structure). The waterjet cutting gantry 414 includes a sliding seat 4141 slidably mounted on a sliding base 4133 and a crossbeam 4142 mounted on two sliding seats 4141 .

[0045] There are multiple water jet cutting heads 43 installed at intervals on the water jet cutting gantry 414, and one water jet cutting head 43 is used to cut one product to be processed.

[0046] Each waterjet cutting head 43 includes a cutting head fixing seat 431 mounted on the waterjet cutting gantry 414, a first rotating motor 432 (the motor shaft of the first rotating motor 432 is vertically arranged) mounted in the cutting head fixing seat 431, a first guide folding plate 433 rotatably mounted on the first rotating motor 432, a second guide folding plate 437 rotatably mounted on the first guide folding plate 433, and a waterjet cutting head 439 mounted on the second guide folding plate 437. Specifically, the first guide folding plate 433 includes a first disc 4331 connected to the motor shaft of the first rotating motor 432 and a first guide carrier plate 4332 formed on the circumference of the first disc 4331 and extending outward, and the angle formed between the first disc 4331 and the first guide carrier plate 4332 is 120-150 degrees, so that the first rotating motor 432 can drive the first disc 4331 to rotate synchronously, and then drive the first guide carrier plate 4332 to rotate synchronously. The second guide folding plate 437 includes a second disc plate 4371 rotatably mounted on the surface of the first guide carrier plate 4332 and a second guide carrier plate 4372 formed on the circumference of the second disc plate 4371 and extending outward, and the angle formed between the second disc plate 4371 and the second guide carrier plate 4372 is 120~150°. At this time, the water cutting cutter head 43 also includes a second rotating motor 434 installed on the surface of the first guide carrier plate 4332 (a driving wheel is installed on the motor shaft of the second rotating motor 434), a rotating joint 435 installed on the surface of the first guide carrier plate 4332 and connected to the second disc plate 4371, a transmission belt 436 connected to the rotating joint 435 and the second rotating motor 434 (the rotating joint 435 and the second disc plate 4371 are coaxially arranged, and there is a transmission wheel between them, so that the transmission belt 436 is wound around the driving wheel and the transmission wheel; the angle formed between the axis line of the second disc plate 4371 and the axis line of the first disc plate 4331 is approximately 40~80°) and a water cutting cutter adapter block 430 installed on the second guide carrier plate 4372 (the water cutting cutter adapter block 430 can also be rotatably installed on the second guide carrier plate 4372 in a conventional manner), and the water discharge cutter head 439 is installed on the water cutting cutter adapter block 430. The water outlet cutter head 439 can be conventional, with one end being the water inlet end and the other end being the water outlet end. The high-pressure water generating assembly 42 is connected to each water cutting cutter head 43 to supply high-pressure water thereto; specifically, the high-pressure water generating assembly 42 is connected to the water inlet end of each water outlet cutter head 439 through a pipeline (the pipeline is usually equipped with an on-off control valve), so that multiple water outlet cutter heads 439 form a parallel structure (not shown in the figure).

[0047] By adopting a specific structure of the water cutting support component 41, the water cutting head 43 and the high-pressure water generating component 42 and other structures, the object to be processed can be processed to obtain a through groove 14'; in addition, the water outlet head 439 can be rotated in at least two directions, thereby achieving a larger rotation of multiple water outlet heads for cutting and processing other structures (in this way, products with slightly different structures can be obtained).

[0048] like Fig.16 The machining center 5 shown mainly includes a matching base assembly 51, a first moving assembly 52, a material transfer platform 53, a material carrier plate 54, a second moving assembly 55, a side support assembly 56 and a machining action assembly 57.

[0049] Among them, the base assembly 51 includes a base 511, a plurality of side mounting seats 512 formed on the side of the base base 511 (the formation method is usually conventional fixing, such as welding or integral molding, etc.), and a plurality of support blocks 513 installed on each side mounting seat 512. At this time, the number of support blocks 513 is the same as the number of side mounting seats 512, so that the support blocks 513 correspond to the side mounting seats 512 one by one, thereby using multiple support blocks 513 to support the base 511 on the ground. The base base 511 can adopt the existing conventional structure, but the following structure is more preferred: the base base 511 includes a hollow support frame (the support frame is composed of four support side panels assembled end to end, and the assembly method is usually welding or one-piece molding, etc.; each support side panel is provided with a plurality of weight-reducing holes), a base support plate fixed to the upper end surface of the support frame (the fixing method is usually welding, the same below), a hollow plate fixed to the lower end surface of the support frame, and a plurality of support vertical plates fixed between the base support plate and the hollow plate and vertically arranged. The base base 511 with such a structure can greatly reduce weight and reduce costs while ensuring the service life, and is convenient for users to flexibly move according to site needs.

[0050] The material transfer platform 53 is slidably mounted on the base assembly 51 through the first moving assembly 52, and its sliding direction is the length direction of the base base 511. In this embodiment, the first moving assembly 52 can adopt the existing conventional structure, but the following structure is more preferred: the first moving assembly 52 includes two slide rail bases 521 installed on the base base 511 and spaced apart (that is, the extension direction of the slide rail base 521 is parallel to the length direction of the base base 511), a first slide rail 522 installed on each slide rail base 521, a first slider 524 slidably mounted on the first slide rail 522 (that is, the first slider 524 is divided into two groups, so that a group of first sliders 524 is correspondingly installed on one first slide rail 522; a group consists of one or more first sliders 524, and the specific number is conventionally selected according to actual needs), a limit stopper 523 installed at the outer end of each slide rail base 521 (the limit stopper 523 also blocks the outer end of the first slide rail 522 to prevent the first slider 524 from sliding off), and a first slider 524 installed on the base base 511. A first screw mounting seat 526 (the first screw mounting seats 526 are usually two and form a pair, spaced apart and arranged opposite to each other) mounted on the first slider 524 and connected to the material transfer platform 53 (the first adapter plates 525 are usually two, which are mounted on the bottom of the first adapter plate 525 and correspondingly connected to multiple first sliders 524), a first screw 527 mounted on the first screw mounting seat 526 and cooperating with the first adapter plate 525 or the material transfer platform 53 (the first screw 527 passes through the first adapter plate 525 or the material transfer platform 53 and is connected thereto by a thread, so that when the first screw 527 rotates, the first adapter plate 525 or the material transfer platform 53 can slide on the first slide rail 522 through the first slider 524) and a first motor mounted at the end of the first screw 527 for driving it to rotate.

[0051] The carrier plate 54 is slidably mounted on the material transfer platform 53 through a second movable component 55, and a plurality of second mounting grooves 541 which are parallel to each other and spaced apart are provided on its upper surface. A plurality of carbon fiber square tubes can be mounted side by side on the carrier plate 54 (the extension direction of the carbon fiber square tubes is perpendicular to the extension direction of the second mounting grooves 541) by conventional mounting aids, so that the sliding direction of the carrier plate 54 is perpendicular to the sliding direction of the material transfer platform 53. The second moving assembly 55 includes two third slide rails 551 installed on the material transfer platform 53 and arranged at an interval (the third slide rails 551 are perpendicular to the first slide rails 522), a plurality of third sliders 552 slidably installed on each of the third slide rails 551, a third screw mounting seat 553 installed on the material transfer platform 53 and located between the two third slide rails 551 (the third screw mounting seats 553 are also two and form a pair, which are arranged at an interval and opposite to each other), a third screw 554 installed on the third screw mounting seat 553 and matched with the material carrier 54 (for example, the bottom surface of the material carrier 54 has a protrusion, the third screw 554 passes through the protrusion and is threadedly connected to the protrusion), and a third motor 555 connected to the end of the third screw 554 for driving it to rotate.

[0052] The side support assembly 56 is installed on the base assembly 51 and is located on one side of the material transfer platform 53. The side support assembly 56 includes a side bottom plate 561 installed on the base base 511 and located on one side of the material transfer platform 53, a side support column 562 installed on the side bottom plate 561, and a plurality of second slide rails 563 installed on the side of the side support column 562 and vertically arranged. The processing action assembly 57 is slidably installed on the plurality of second slide rails 563. Here, by adding the side bottom plate 561, the side support column 562 is not directly connected to the base base 511, so that the wear is mainly concentrated on the side bottom plate 561. The side bottom plate 561 can be replaced during subsequent maintenance, which is very convenient. In this embodiment, the side support assembly 56 also includes a second slider 564 slidably mounted on each second slide rail 563, a second screw mounting seat 565 mounted on the side of the side support column 562 and located between the second slide rails 563, a second screw 566 mounted on the second screw mounting seat 565 and cooperating with the processing action assembly 57 (the second screw 566 is threadedly connected to the processing action assembly 57), and a second motor 567 mounted at the end of the second screw 566.

[0053] The processing action assembly 57 is escalably mounted on the side support assembly 56 and corresponds to the carrier plate 54, and is used to process a plurality of carbon fiber square tubes carried on the carrier plate 54. The processing action assembly 57 includes an action mounting head 571 mounted on the second slider 564, a knife seat 572 mounted on the action mounting head 571, a knife head detachably mounted on the knife seat 572, a booster cylinder mounting frame 573 mounted on the action mounting head 571, and a knife-beating cylinder 574 mounted on the booster cylinder mounting frame 573 and matched with the knife head.

[0054] Since the cross section obtained by the aforementioned multi-head water jet cutting machine 4 is relatively rough (or uneven), it is necessary to use the cutter head of the machining center 5 to fine-process it to improve the smoothness or flatness of its surface. By using a base assembly 51, a material transfer platform 53, a material loading plate 54, a side support assembly 56 and a machining action assembly 57 of a specific structure to cooperate, multiple carbon fiber square tubes can be installed on the material loading plate through the installation groove for corresponding processing, which not only greatly simplifies the structure of the machining center and reduces the cost; but also can process multiple carbon fiber square tubes with high processing efficiency.

When the first transmission shaft 8125 rotates, it can drive the first conveyor belt 8129 to rotate synchronously), a support vertical plate 8127 installed on the inner wall of any feed installation side plate 8124, and a first feed motor 8128 installed on the support vertical plate 8127 and connected to any first transmission shaft 8125 (the edge of the first transmission shaft 8125 has a transmission wheel matching the first feed belt) through the first feed belt. In this way, when the first feed motor 8128 is working, it drives the first transmission shaft 8125 to transmit through the first feed belt and the transmission wheel, and then drives the first conveyor belt 8129, thereby realizing the transportation of materials on the first conveyor belt 8129.
