[0032] Embodiment 1:
[0033] A component processing and detection integrated device, such as Figures 1 to 7As shown, it includes a base 1 and a cutting component for processing cylindrical parts and a supporting component for stabilizing cylindrical parts, a sliding member is installed on the top outer wall of the base 1, and a rotating component is slidably connected to the sliding member, a vertical plate 7 is fixed to the top outer wall of the base 1 by bolts, and a mounting cylinder 42 is fixed to the outer wall of one side of the vertical plate 7 by screws, and a through hole opened at one end of the mounting cylinder 42 is slidably connected to a T-shaped rod 44, and a spring four 43 is clamped between the inner wall of one side of the T-shaped rod 44 and the inner wall of one side of the mounting cylinder 42, a receiving plate 36 is welded to one end of the T-shaped rod 44, and a vertical rod 38 is welded to the inner wall of the receiving plate 36, a slider 13 is slidably connected to the outer wall of the vertical rod 38, and a spring three 41 is clamped between the bottom of the slider 13 and the inner wall of the receiving plate 36, a pressure sensor 30 is fixed to one end of the slider 13 by screws, and a sleeve 37 is fixed to the outer wall of one side of the pressure sensor 30 by screws, and a ball 45 is rotatably connected inside the sleeve 37;
[0034] The cutting assembly can be used to cut the cylindrical parts into required lengths according to the needs. After the cylindrical parts are cut, the flatness of the cut surface needs to be tested to ensure the cutting yield. When cutting the cylindrical parts, the support assembly can be used to support the cylindrical parts, and the sliding part can be used to adjust the horizontal position of the rotating assembly.
[0035] As the rotating assembly continuously applies pressure to one end of the cylindrical component, the spring 43 is continuously stretched under the action of pressure until one end of the T-bar 44 and the inner wall of one side of the mounting tube 42 fit together. At this time, the cylindrical component is fixed between the rotating assembly and the ball 45, thereby ensuring the stability of the cylindrical component when it is subsequently cut using the cutting assembly.
[0036] The sliding member includes a limit rod 10 and a lining plate 11, the two lining plates 11 are fixed to the top outer wall of the base 1 by bolts, and the limit rod 10 is fixed between the two lining plates 11 by bolts, and the outer wall of the limit rod 10 is slidably connected with a sliding plate 12, a lead screw 25 is rotatably connected between the two lining plates 11, and the sliding plate 12 and the lead screw 25 are connected by a nut, a driving motor 2 is fixed to the outer wall of one side of the lining plate 11 by bolts, and the output end of the driving motor 2 is connected to one end of the lead screw 25 by a coupling, and the rotating assembly includes a rotating motor 23 and a card plate 24, the rotating motor 23 is fixed to the outer wall of one side of the sliding plate 12 by bolts, and the output end of the rotating motor 23 is connected to the card plate 24 by a coupling;
[0037] The driving motor 2 can be used to drive the lead screw 25 to rotate, so that the sliding plate 12 moves horizontally under the guidance of the limit rod 10, and then the horizontal position of the clamping plate 24 is adjusted. The interior of the clamping plate 24 is an inverted cone structure, so that the clamping plate 24 can resist cylindrical parts of different outer diameters and center the cylindrical parts at the same time, ensuring that the axis of the cylindrical parts and the center point of the clamping plate 24 coincide with each other.
[0038] The cutting assembly includes an electric telescopic rod 14 and a support seat 15, the support seat 15 is fixed to the top outer wall of the base 1 by bolts, and the electric telescopic rod 14 is fixed to the top outer wall of the support seat 15 by bolts, the output end of the electric telescopic rod 14 is fixed with a mounting plate 4 by a pin, a cutting motor 5 is fixed to the outer wall of one side of the mounting plate 4 by bolts, and a cutting saw blade 3 is fixed to the output end of the cutting motor 5 by a pin;
[0039] By providing an electric telescopic rod 14, the height of the cutting saw blade 3 in the longitudinal direction can be adjusted, and the cutting motor 5 can drive the cutting saw blade 3 to rotate, so that the cutting saw blade 3 cuts the cylindrical parts during the process of rotating downward.
[0040] The support assembly includes a centering mechanism and a receiving mechanism, the receiving mechanism includes a support frame 29 and an elastic support member slidably connected to the outer wall of the support frame 29, the elastic support member includes a spring 1 21 and a guide rod 22, the guide rod 22 is slidably connected to the outer wall of the support frame 29, and the spring 1 21 is clamped between the guide rod 22 and the support frame 29, one end of the guide rod 22 is fixed with a connection seat 20, and the inner wall of the connection seat 20 is rotatably connected with a roller 19;
[0041] Before fixing the cylindrical component, the cylindrical component is placed in the gap between the multiple connecting seats 20, and the elastic force of the spring 1 21 is used to keep the roller 19 and the outer wall of the cylindrical component in contact with each other, so as to achieve preliminary support for the cylindrical component.
[0042] The centering mechanism includes a support frame 8 and a clamping member slidably connected to the circumferential outer wall of the support frame 8, the clamping member includes a support seat 31 and a retractable rod 32, the retractable rod 32 is slidably connected to the circumferential outer wall of the support frame 8, and the support seat 31 is welded to one end of the retractable rod 32, and the other end of the retractable rod 32 is welded with a U-shaped seat 28, and the inner wall of the U-shaped seat 28 is rotatably connected with a roller 29, the centering mechanism also includes a support plate 6 and an electric telescopic rod 218, the support plate 6 is fixed to the top outer wall of the base 1 by bolts, and the electric telescopic rod 218 is fixed to the outer wall of one side of the support plate 6 by bolts, the output end of the electric telescopic rod 218 is fixed with a card seat 17 by a pin, one end of the card seat 17 is clamped with a spring 27, and the end of the spring 27 away from the card seat 17 is clamped with a moving seat 26, and a connecting rod 16 is rotatably connected between the inner wall of the moving seat 26 and the inner wall of the support seat 31;
[0043] When the columnar component needs to be centered, the electric telescopic rod 218 is used to drive the spring 27 and the moving seat 26 to make a return movement. During the movement of the moving seat 26, the connecting rod 16 is used to convert the lateral movement of the moving seat 26 into the linear movement of the roller 29 along the support frame 18. The multiple rollers 29 are synchronously contracted inwardly so that the columnar component can be clamped and fixed while achieving the centering of the columnar component.
[0044] When the cylindrical parts are cut, the electric telescopic rod 18 drives the holder 17 to move in the opposite direction, so that the plurality of rollers 29 move outward at the same time, so that the cut fertilizer falls under the action of its own gravity. At the same time, the receiving mechanism can support the cut cylindrical parts, which is convenient for the subsequent flatness detection of the cut surface of the cylindrical parts.
[0045] When it is necessary to detect the flatness of the cross-section of the cylindrical component, the sliding member is used to drive the rotating assembly to move horizontally. During the horizontal movement, the rotating assembly drives the cut cylindrical component to move in the direction close to the ball 45. When the cross-section of the cylindrical component moves to fit the ball 45, it stops moving. Then, the rotating motor 23 is used to drive the cut cylindrical component to rotate. During the rotation, the cross-section of the cylindrical component rolls along the outer wall of the spherical surface of the ball 45. During the rolling, the pressure is monitored by the pressure sensor 30. If the cross-section of the cylindrical component is relatively flat, the pressure value monitored by the pressure sensor 30 remains unchanged during the circular motion of the cross-section of the cylindrical component. If the cross-section of the cylindrical component is uneven, the pressure value monitored by the pressure sensor 30 fluctuates during the circular motion of the cross-section of the cylindrical component. In this way, the flatness of the cross-section of the cylindrical component can be quickly detected.
[0046] When the present embodiment is in use, the columnar component to be cut is placed on the receiving mechanism of the support assembly, and the elastic force of the spring 21 of the elastic support member is used to make the roller 19 fit closely with the outer wall of the component, and the electric telescopic rod 18 is started, and the contraction rod 32 and the roller 29 of the clamping member are driven to shrink inward synchronously through the connecting rod 16 to clamp and center the component to ensure that the axis of the component is aligned with the cutting assembly, and the drive motor 2 is started, and the screw 25 is connected to the nut of the sliding plate 12 to adjust the horizontal position of the rotating assembly clamp 24 to adapt to components of different lengths, and the electric telescopic rod 14 is started to adjust the height of the cutting saw blade 3 to an appropriate position, and then the cutting motor 5 is started to drive the cutting The saw blade 3 rotates and moves downward to cut the parts. After cutting, the electric telescopic rod 18 moves in the opposite direction to release the clamping parts. The parts fall to the receiving mechanism under the action of their own gravity. Then, the position of the rotating assembly is adjusted by the sliding part so that the cut surface of the part is close to the ball 45. The rotating motor 23 is started to drive the part to rotate so that the cut surface rolls along the spherical surface of the ball 45. During the rotation of the part, the contact pressure between the cut surface and the ball 45 is monitored by the pressure sensor 30 in the casing 37. If the cut surface is flat, the pressure value monitored by the pressure sensor 30 remains stable; if the cut surface is uneven, the pressure value will fluctuate. According to the monitoring results of the pressure sensor 30, the flatness of the cut surface of the part can be quickly judged.
[0047] Embodiment 2:
[0048] A component processing and detection integrated device, such as Figures 1 to 7 As shown, in order to detect the flatness of different positions on the cross section of the cylindrical component, this embodiment makes the following supplements on the basis of embodiment 1: a driving rod 35 is welded to the outer wall of one side of the clamping seat 17, and the driving rod 35 is slidably connected to the moving seat 26, and an inclined plate 34 is fixed to one end of the driving rod 35 by screws, and a swing arm 40 is rotatably connected to the inner wall of the vertical plate 7, and a sliding sleeve 39 is slidably connected to one end of the swing arm 40, and the sliding sleeve 39 is rotatably connected to the slider 13, and the other end of the swing arm 40 is rotatably connected to a roller 33 used in conjunction with the inclined plate 34;
[0049] In order to facilitate the detection of the flatness of different positions on the cross-section of the cylindrical component and ensure the accuracy of the detection results, when the electric telescopic rod 18 drives the inclined plate 34 and the driving rod 35 to move horizontally, the inclined surface of the inclined plate 34 squeezes the roller 33. After the roller 33 is squeezed, the lever principle is used to move the slider 13 along the vertical rod 38, thereby adjusting the position of the ball 45 in the vertical direction, and then adjusting the contact position of the ball 45 and the cross-section of the cylindrical component, so as to facilitate the detection of the flatness of different positions on the cross-section of the cylindrical component.
