DETAILED DESCRIPTION

[0033] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] Embodiment: A metal parts processing and cutting machine, such as Figure 1-Figure 5As shown, it includes a frame 1, a working platform 2, an arc frame 21, a rotating shaft 22, a gantry 3, a mounting seat 23, a cutting machine assembly 4, a sliding frame 41, a driving shaft 42, a first gear set 43, a gear ring 45, a U-shaped frame 24 and a placement frame 241. The working platform 2 is provided at the top rear side of the frame 1, and the front end of the top of the working platform 2 is provided with an arc frame 21 for conveying workpieces. The arc frame 21 is provided with an arc groove for placing round pipe workpieces. The top of the working platform 2 is rotatably installed with a rotating shaft 22 parallel to the working platform 2 through a mounting piece. A mounting seat 23 is also installed on the top plane of the working platform 2. The mounting seat 23 is provided below the extension line of the rotating shaft 22. The gantry 3 is installed on the rotating shaft 22. The gantry 3 consists of two L-shaped connecting members installed on the rotating shaft 22. The connecting frame is composed of two parallel horizontal plates installed between the two connecting frames, the distance between the two horizontal plates is adapted to the diameter distance of the arc groove of the arc frame, the horizontal gantry 3 is provided with a driving component for driving the workpiece to move horizontally along the arc frame 21, the driving component is arranged between the two horizontal plates, a sliding frame 41 is slidingly provided on the mounting seat 23, a driving shaft 42 is rotatably installed on the sliding frame 41, a cutting machine assembly 4 is installed on the driving shaft 42, and the position of the cutting machine assembly 4 is flexibly adjusted by sliding the sliding frame 41 on the mounting seat 23 to meet the cutting requirements of different lengths; the cutting machine assembly 4 intersects the extension line of the gantry 3 vertically, the driving shaft 42 is arranged on the extension line of the rotating shaft 22, and a gear ring 45 is provided at the end of the rotating shaft 22 near the driving shaft 42 , a first gear set 43 meshing with each other is provided in the ring gear 45, one gear of the first gear set 43 meshes with the ring gear 45, and the other gear is connected to the extended end of the driving shaft 42. It is worth noting that a driving motor for driving the driving shaft 42 to rotate is installed on the sliding frame 41, and the driving motor drives the driving shaft 42 to rotate 1 / 4 circle to make the cutting machine assembly 4 approach or move away from the workpiece. When the cutting machine assembly 4 gradually approaches downward, the workpiece can be cut. When the cutting machine assembly 4 moves away from the workpiece, the driving shaft 42 drives the rotating shaft 22 to rotate in the opposite direction through the first gear set 43 and the ring gear 45, so that the driving component on the gantry 3 approaches the arc frame 21. When the rotating shaft 22 rotates 1 / 4 circle, the gantry 3 is located directly above the arc frame 21. The driving component on the frame 3 can drive the workpiece in the arc groove of the arc frame 21 to move horizontally, so as to transport the workpiece to the cutting station. In this way, the timing coordination of the cutting mechanism and the feeding mechanism is realized, so as to achieve the effect of automatic feeding and automatic cutting, thereby improving the cutting efficiency; a U-shaped frame 24 is slidingly provided on the front side of the mounting seat 23, and the sliding U-shaped frame 24 is used to adjust the position of the U-shaped frame 24 according to the required cutting length, so as to meet the cutting requirements of different lengths. A placement frame 241 is provided at the end where the U-shaped frame 24 is separated from the mounting seat 23, and the placement frame 241 is provided on the extension line of the arc frame 21. The placement frame 241 is used to provide a placement plane for the end of the workpiece away from the arc frame 21, and the workpiece is placed between the arc frame 21 and the placement frame 241.

[0035] like Figure 3 and Figure 4 As shown, the driving assembly includes a plurality of feeding friction wheels 31 installed between the two horizontal plates of the gantry 3, a feeding motor 32 installed on the gantry 3 and a belt 33 wound between the feeding friction wheels 31 and the output shafts of the feeding motor 32. When the gantry 3 rotates to the top of the arc frame 21, the feeding friction wheels 31 are opposite to the arc groove of the arc frame 21. It is worth noting that the rotation direction of the feeding friction wheels 31 is consistent with the movement direction of the workpiece in the arc frame 21; when the feeding motor 32 is working, the feeding motor 32 drives the feeding friction wheel 31 to rotate through the belt 33. Since the feeding friction wheel 31 is in contact with the surface of the workpiece in the arc frame 21, when the feeding friction wheel 31 rotates, it can drive the workpiece to move horizontally along the arc groove of the arc frame 21, thereby achieving the effect of transporting the workpiece to the cutting station.

[0036] like Figure 11 As shown, a guide roller 212 is arranged in an array at the lowest point of the arc groove of the arc frame 21, and rolling balls 211 are arranged on the two inner walls of the arc groove of the arc frame 21 with the guide roller 212 as the center. The guide roller 212 and rolling ball 211 structure is arranged in the arc frame 21, thereby significantly reducing the friction resistance of the workpiece on the arc frame 21 and ensuring the stability of the workpiece transportation.

[0037] When the round tube needs to be transported to the cutting machine assembly 4 for cutting, the driving motor first drives the driving shaft 42 to rotate forward, and the driving shaft 42 drives the ring gear 45 to rotate in the opposite direction through the first gear set 43, and drives the rotating shaft 22 to rotate in the opposite direction through the ring gear 45, and makes the rotating shaft 22 rotate 1 / 4 circle, thereby driving the gantry 3 to rotate 90 degrees to the side of the arc frame 21, so that the feeding friction wheel 31 contacts the surface of the workpiece in the arc frame 21; when the feeding motor 32 is working, its power is transmitted to the feeding friction wheel 31 through the belt 33, so that The feeding friction wheel 31 is driven to rotate, and the workpiece is driven to move horizontally along the arc frame 21 through the rotation of the feeding friction wheel 31. The setting of the ball 211 and the guide roller 212 can effectively reduce the friction between the workpiece and the arc frame 21; when one end of the workpiece is placed on the placement rack 241, at this time, the driving shaft 42 rotates in the reverse direction, and the rotating shaft 22 is driven to rotate forward through the first gear set 43 and the ring gear 45, so that the gantry 3 moves upward away from the arc frame 21. At this time, the cutting machine assembly 4 rotates toward the direction of the workpiece, thereby completing the cutting operation of the workpiece.

[0038] like Figure 1 and Figure 6As shown, a loading rack 101 is provided on the front side of the top of the frame 1, and the upper end of the loading rack 101 is connected to the arc frame 21. The loading rack 101 is an inclined "V"-shaped structure, and a notch is provided on the inclined surface connected to the arc frame 21. The notch extends from the lowest point of the loading rack 101 to its highest point. A feeder 5 is provided at the notch of the loading rack 101, and a feeding conveyor 51 is provided on the feeder 5. The feeding conveyor 51 is located in the notch of the loading rack 101, and feeding hook plates 52 for limiting the workpieces are evenly spaced on the feeding conveyor 51. When the feeding conveyor 51 moves upward, the workpieces in the loading rack 101 are placed one by one on the feeding conveyor 51 through its feeding hook plates 52, so that the workpieces are transported one by one into the arc groove of the arc frame 21, thereby achieving the effect of automatic loading.

[0039] When loading is required, the metal round tubes are placed on the loading rack 101. When the feeding conveyor 51 is working, the metal round tubes are placed on the feeding conveyor 51 piece by piece through the feeding hook plate 52, and are transported to the arc groove of the arc frame 21 through the feeding conveyor 51, thereby realizing the loading of the round tubes from the loading rack 101 onto the arc frame 21 piece by piece.

[0040] like Figure 1 、 Figure 2 、 Figure 7 and Figure 9 As shown, a unloading platform 6 is installed on the frame 1, and the unloading platform 6 is arranged below the cutting machine assembly 4. The unloading platform 6 is symmetrically rotated with a unloading conveyor belt 8. Specifically, a horizontal axis is symmetrically rotated between the bottom brackets of the unloading platform 6, and a transmission roller is installed on the horizontal axis. The unloading conveyor belt 8 is wrapped around the front and rear transmission rollers. It is worth noting that a power system for driving the horizontal axis to rotate to drive the transmission roller and the unloading conveyor belt 8 to move can be provided at the bottom of the unloading platform 6, so as to improve the unloading efficiency; limiting protrusions 80 are evenly spaced on the unloading conveyor belt 8, and the setting of the limiting protrusions 80 can achieve the effect of isolating the workpieces from each other, thereby achieving the function of unloading the workpieces one by one.

[0041] like Figure 7 As shown, limit plates 61 are symmetrically slidably provided on the left and right sides of the top of the unloading platform 6, and an electric screw 62 is provided at the bottom of the unloading platform 6. The electric screw 62 includes a dual-axis motor installed at the bottom of the unloading platform 6 and two screws connected to the output shaft of the dual-axis motor. The threads of the two screws are in opposite directions. A Z-shaped frame 63 is threadedly connected to the electric screw 62. The Z-shaped frame 63 is connected to the limit plate 61 through a connecting rod 64. The electric screw 62 drives the Z-shaped frames 63 on both sides to move closer to or away from each other, thereby driving the limit plates 61 on the left and right sides to move closer to or away from each other, thereby adjusting the distance between the two limit plates 61 according to the length of the workpiece, so as to adapt to workpieces of different lengths.

[0042] like Figure 7 and Figure 8 As shown, a grinding piece mounting frame 7 is installed on the back of the limiting plate 61. The grinding piece mounting frame 7 is set in a "mouth" shape. Transmission rollers 71 are rotatably set at the left and right ends of the grinding piece mounting frame 7, and at least one transmission roller 71 is connected to the grinding motor 74 installed on the limiting plate 61 through a second gear set 73. The two gears of the second gear set 73 include a gear connected to the output shaft of the grinding motor 74 and a gear connected to the end of the transmission roller 71. The two gears mesh with each other. A grinding belt 72 is set between the transmission rollers 71. The grinding belt 72 is set at the opening of the limiting plate 61. The grinding belt 72 is used to grind the end of the workpiece. When in use, the grinding motor 74 drives the transmission roller 71 to rotate through the second gear set 73, and the transmission roller 71 drives the grinding belt 72 to move. The movement of the grinding belt 72 causes relative movement between it and the end of the workpiece, thereby deburring the end of the workpiece.

[0043] After the workpiece is cut, it falls down onto the unloading platform 6, and slides down the slope of the unloading platform 6 onto the unloading conveyor belt 8. The workpiece is limited by the limiting protrusion 80 on the unloading conveyor belt 8. As the unloading conveyor belt 8 moves forward, the workpiece moves forward with the unloading conveyor belt 8, and the two ends of the workpiece move relative to the grinding belt 72, thereby deburring the end of the workpiece.

[0044] like Figure 10 As shown, a support plate 9 is provided on the end of the arc frame 21 slidingly toward the U-shaped frame 24, an N-shaped frame 91 is symmetrically provided on the top of the support plate 9, an arc-shaped limiter 92 is provided between the N-shaped frames 91 for sliding, a spring 93 is provided between the upper end of the N-shaped frame 91 and the arc-shaped limiter 92, and a lower pressure block 94 is provided on the top of at least one N-shaped frame 91. When the gantry 3 rotates to above the arc frame 21, the lower pressure block 94 contacts the gantry 3.

[0045] When the gantry 3 approaches the arc frame 21, when the gantry 3 contacts the lower pressing block 94, the lower pressing block 94 drives the n-shaped frame 91 and the support plate 9 to move downward under the squeezing action of the downward pressure force of the gantry 3, and the spring 93 is deformed under the downward force of the n-shaped frame 91, thereby driving the arc limiter 92 to move downward, so that the arc-shaped opening of the arc limiter 92 and the arc groove of the arc frame 21 just form a circular passage for the workpiece to pass through; when the gantry 3 moves away from the upward, since the workpiece passes between the arc limiter 92 and the support plate 9, the arc limiter 92 effectively limits the workpiece under the action of the elastic force of the spring 93, thereby preventing the cutting machine assembly 4 from tilting at one end of the arc frame 21 during the cutting operation and affecting the cutting operation.

[0046] like Figure 1 and Figure 12As shown, a liquid storage tank 10 is provided on the working platform 2, and nozzles 1001 are provided on both sides of the cutting blade of the cutting machine assembly 4. The nozzles 1001 are connected to the liquid storage tank 10 through an infusion tube.

[0047] like Figure 1 and Figure 13 As shown, a drain plate 11 is provided at the inclined opening of the unloading platform 6, and a collecting frame 12 is slidably provided on the frame 1. The collecting frame 12 is provided below the drain plate 11, and a filter screen 13 is detachably provided in the collecting frame 12.

[0048] When the cutting machine assembly 4 is in cutting operation, the coolant in the liquid storage tank 10 is atomized and sprayed to both sides of the cutting blade through the nozzle 1001, effectively reducing the cutting temperature and flushing away debris; the drain plate 11 separates the cutting fluid to the collection frame 12, and the filter screen 13 realizes the recovery of waste chips and coolant.

[0049] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
