Description

Technical Field

[0001] This invention belongs to the field of insulator production, specifically relating to a blank scraping device for insulator production. Background Technology

[0002] Insulators, as core insulating components in power systems, are mainly installed between conductors at different potentials or between conductors and grounding components. They are crucial equipment for ensuring the safe operation of power transmission networks. Their core function is to withstand mechanical loads while maintaining rated voltage, thereby ensuring the safe and stable operation of transmission lines. In power systems, insulators not only need excellent insulation performance but also sufficient mechanical strength to cope with the challenges posed by complex natural environments and varying power loads. In the insulator manufacturing process, blank scraping is a key step determining product precision and performance. This process, through precise cutting, removes excess material from the surface of the insulator blank, ensuring the product achieves the required dimensional accuracy and surface finish, laying a solid foundation for subsequent processes such as glazing and assembly.

[0003] A blank scraping device for insulator production, with announcement number CN116373085A, controls a small scraper to approach the insulator blank along a preset trajectory. When the small scraper contacts the blank surface, it can perform fine scraping on the upper curved surface to remove the surface material. Subsequently, a large scraper completes a secondary feed through an independent drive unit to efficiently cut the outer circumferential surface of the blank. This blank scraping device for insulator production innovatively adopts a dual-tool collaborative operation mode, which can significantly improve processing efficiency compared with traditional equipment. Traditional insulator processing equipment generally suffers from three major technical bottlenecks: unidirectional rotary cutting results in a single processing trajectory, requiring multiple clamping for complex curved surface processing, extending the production cycle; manual adjustment of tool feed is prone to deviation, directly affecting the consistency of insulation gaps in insulators; and fixed cutting parameters cannot adapt to the differentiated processing needs of ceramics, glass, and composite materials, resulting in a low finished product qualification rate when producing multiple materials. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides a blank scraping device for insulator production, comprising a housing, a protective cover fixedly mounted on the top of the housing, a motor disposed at the bottom of the inner wall of the housing, the output end of the motor being connected to a main shaft, a placement disk fixedly connected to the top of the main shaft, an insulator blank disposed on the surface of the placement disk, a rotary cutting device assembled inside the protective cover, the rotary cutting device comprising a pulley one mounted in the middle of the main shaft, a driven shaft rotatably mounted on the inner wall of the housing, a sliding assembly mounted on the bottom of the inner wall of the protective cover, and a turntable slidably mounted on the surface of the inner wall of the protective cover, a pulley two mounted on the lower side of the driven shaft, the pulley one and the pulley two being connected by belt drive, a gear one mounted on the upper side of the driven shaft, a rotating shaft fixedly mounted on the bottom of the turntable, a gear two fixedly mounted on the bottom of the rotating shaft, a cutter disposed on the outer side of the turntable, a rotating cylinder fixedly mounted on the top of the turntable, a handle fixedly mounted on the bottom of the rotating cylinder, and a handle sleeve disposed on the outer side of the handle.

[0006] Preferably, the sliding assembly includes a sliding wheel mounted on the bottom of the handle and a hollow disc slidably mounted on the top of the rotating drum.

[0007] Preferably, the bottom of the turntable is equipped with a sliding component, and the rotating cylinder is equipped with a sliding component.

[0008] Preferably, the inner wall of the hollow disc is provided with a slide rail, the sliding wheel cooperates with the slide rail, and the first gear meshes with the second gear.

[0009] Preferably, the surface of the placement tray is provided with a clamping device for clamping the insulator blank.

[0010] Preferably, the clamping device includes a pulley three mounted on the upper side of the main shaft, a rotating rod that passes through and is rotatably connected to the surface of the outer casing, a fixing block fixedly mounted on the surface of the placement tray, and a fixing disc fixedly mounted on the surface of the placement tray. A pulley four is mounted at the bottom of the rotating rod, and a bevel gear one is mounted at the top of the rotating rod. The pulley three and pulley four are connected by a transmission belt. A lead screw is rotatably connected to the right side of the fixing block, and a bevel gear two is mounted on the right side of the lead screw. A connecting block is mounted in the middle of the lead screw, and a telescopic rod is fixedly mounted at the top of the connecting block. A circular turntable is fixedly mounted on the right side of the telescopic rod, and a hinged circular rod one is fixedly mounted at the top of the fixing disc. A fixing rod is mounted in the middle of the hinged circular rod one, and a hinged circular rod two passes through and is rotatably connected to the right side of the fixing rod.

[0011] Preferably, the circular turntable and the fixed disc are rotatably connected, and the second bevel gear meshes with the first bevel gear.

[0012] Preferably, the inner wall of the rotating drum is equipped with a lifting device for raising and lowering the turntable.

[0013] Preferably, the lifting device includes a rotating rod that passes through and is rotatably connected to the inner wall of the handle. A rotating disk is fixedly installed on the top of the rotating rod, a throttle is fixedly installed on the top of the rotating disk, a screw is fixedly installed on the top of the rotating rod, a nut is fitted on the lower side of the screw, a connecting rod is fixedly installed on the outer side of the nut, and a sliding block is fixedly installed on the right side of the connecting rod.

[0014] Preferably, the sliding block is slidably connected to the inner wall of the turntable, and the sliding block is made of wear-resistant material.

[0015] The advantages of this application are: (1) The starting motor of this application drives the turntable to rotate under the action of power transmission, providing a force opposite to the rotation direction of the insulator blank, driving the cutter on the outside of the turntable to rotate and move through the slide rail of the hollow disc. The operator rotates the handle sleeve to perform rotary cutting on the insulator blank, which greatly improves the cutting efficiency.

[0016] (2) This application uses the meshing transmission of bevel gear one and bevel gear two to enable the lead screw to drive the connecting block and telescopic rod to move horizontally, thereby realizing the fixed rod of the circular turntable to firmly clamp the insulator blank, effectively preventing the blank from shifting or shaking during the scraping process, improving the scraping accuracy. The clamping force can be adjusted in real time to achieve adaptive and stable clamping of the diameter insulator blank. Compared with the traditional manual chuck, the axial offset is lower, which reduces the surface roughness of the machined surface and effectively solves the problem of edge chipping caused by uneven clamping stress in ceramic / glass blanks, thus comprehensively improving the scraping accuracy.

[0017] (3) In this application, the operator rotates the handle on the rotary table, causing the screw to rotate. When the screw rotates, the nut will move up and down. A connecting rod is fixedly installed on the outside of the nut, and a sliding block is fixedly installed on the right side of the connecting rod. Therefore, the up and down movement of the nut will cause the sliding block to slide on the inner wall of the rotary table, thereby causing the rotary table to move up and down to cut the insulator blank. This makes the cutting process more flexible and allows the cutting height to be adjusted according to different specifications of insulator blanks, improving the applicability of the device and the cutting quality, and greatly improving the production efficiency of insulator blank scraping.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-7 The diagram illustrates a blank scraping device for insulator production, comprising a housing 200, with a protective cover 100 fixedly mounted on the top of the housing 200, providing both safety protection and visual observation functions, effectively preventing the splashing of processing debris. A motor 300 is installed at the bottom of the inner wall of the housing 200, with its output end connected to a main shaft 400. A placement disc 500 is fixedly connected to the top of the main shaft 400, with a rubber anti-slip pad on its surface to support the insulator blank 600 and rotate synchronously with the main shaft, achieving workpiece rotational feeding. The surface of the placement disc 500 is provided with the insulator blank 600. A rotary cutting device 700 is assembled inside the protective cover 100, comprising a pulley 703 mounted in the middle of the main shaft 400, a driven shaft 701 rotatably mounted on the inner wall of the housing 200, a sliding assembly mounted on the bottom of the inner wall of the protective cover 100, and a turntable 708 slidably mounted on the surface of the inner wall of the protective cover 100. The sliding assembly includes... A sliding wheel 711 is fitted at the bottom of the handle 712, and a hollow disc 710 is slidably mounted on the top of the rotating drum 714. A slide rail is provided on the inner wall of the hollow disc 710, and the sliding wheel 711 cooperates with the slide rail. A sliding assembly is mounted at the bottom of the rotating disc 708, and a sliding assembly is mounted on the rotating drum 714. A second pulley 702 is mounted on the lower side of the driven shaft 701. The first pulley 703 and the second pulley 702 are connected by a belt 704. A toothed... A rotating shaft 707 is fixedly installed at the bottom of a turntable 708, and a gear 706 is fixedly installed at the bottom of the rotating shaft 707. Gear 705 meshes with gear 706. A cutter 709 is provided on the outer side of the turntable 708, which performs radial scraping on the blank as the turntable 708 rotates at high speed. A rotating cylinder 714 is fixedly installed on the top of the turntable 708, and a handle 712 is fixedly installed at the bottom of the rotating cylinder 714. A handle sleeve 713 is provided on the outer side of the handle 712.

[0022] In practical use, the power transmission and cutting adjustment process of the above-mentioned equipment is as follows: First, the operator starts the motor 300. The output end of the motor 300 drives the main shaft 400 to rotate. The top of the main shaft 400 is fixedly connected to the placement plate 500, which drives the insulator blank 600 on it to rotate clockwise. At the same time, the pulley 703 mounted on the middle of the main shaft 400 through a flat key rotates synchronously with the main shaft 400. Through the belt 704, the pulley 702 on the lower side of the driven shaft 701 is driven to rotate. The rotation of the pulley 702 drives the driven shaft 701 to rotate. The rotation of the driven shaft 701 drives the spur gear 705 on the upper side of the driven shaft 701 to rotate. The spur gear 705 meshes with the gear 706 on the bottom shaft 707 of the turntable 708 to transmit power. Finally, the turntable 708 is driven to rotate counterclockwise, forming a reverse cutting motion with the insulator blank 600. The outer side of the turntable 708 is connected by a screw... The fixed carbide cutter 709 rotates at high speed with the turntable 708, cutting the rotating insulator blank 600. During the cutting process, the operator can apply torque to the handle 712 through the handle sleeve 713 to rotate it. Since the handle 712 is fixedly connected to the rotating cylinder 714, and the rotating cylinder 714 is fixedly connected to the turntable 708, the hollow disc 710 is equipped with a sliding component at the bottom of the turntable 708, and a rectangular slide rail is set on the inner wall of the hollow disc 710 to realize the movement. This structure allows the turntable 708 to slide smoothly in the horizontal direction while rotating. The sliding speed is controlled by the handle operation. Through this compound motion control, the operator can fine-tune the cutting position so that the cutter 709 is accurately aligned with the blank processing surface. Compared with the traditional fixed cutting method, the surface roughness is reduced, the cutting roundness error is very small, the processing time of a single piece is shortened, and the problem of blank scrap caused by positioning deviation is avoided, thus improving the material utilization rate.

[0023] Example 2, as Figures 1-10The diagram illustrates a blank scraping device for insulator production. A clamping device 800 for holding insulator blanks 600 is provided on the surface of a placement disc 500. This device achieves automatic centering and clamping of the blank through a mechanical linkage structure, effectively improving processing stability. The clamping device 800 includes a pulley 801 mounted on the upper side of a main shaft 400, a rotating rod 804 penetrating and rotatably connected to the surface of a housing 200, a fixing block 808 fixedly mounted on the surface of the placement disc 500, and a fixing disc 812 fixedly mounted on the surface of the placement disc 500. A pulley 802 is mounted at the bottom of the rotating rod 804, and a bevel gear 805 is mounted at the top of the rotating rod 804. The pulleys 801 and 802 are connected by a transmission belt 803. A lead screw 807 is rotatably connected to the right side of the fixing block 808. A second bevel gear 806 is mounted on the side, which meshes with a first bevel gear 805. A connecting block 809 is mounted in the middle of the lead screw 807 to form a helical transmission pair. A telescopic rod 810 is fixedly mounted on the top of the connecting block 809, with a built-in compression spring for length compensation. A circular turntable 811 is fixedly mounted on the right side of the telescopic rod 810. The circular turntable 811 and the fixed disc 812 have a relative rotation structure to ensure that the clamping mechanism does not interfere when rotating synchronously with the placement disc. The circular turntable 811 and the fixed disc 812 are rotatably connected. A first hinged round rod 813 is fixedly mounted on the top of the fixed disc 812. A fixed rod 815 is mounted in the middle of the first hinged round rod 813. The angle change of the linkage mechanism realizes adaptive clamping of blanks of different diameters. A second hinged round rod 814 is rotatably connected through the right side of the fixed rod 815.

[0024] When using the above equipment, first start the motor 300. The motor 300 drives the first bevel gear 805 to rotate. The first bevel gear 805 meshes with the second bevel gear 806, causing the second bevel gear 806 to rotate. The rotation of the second bevel gear 806 drives the lead screw 807 to rotate. The lead screw 807 drives the connecting block 809 to move horizontally. The movement of the connecting block 809 drives the telescopic rod 810 to move. The telescopic rod 810 is rigidly connected to the circular turntable 811 on the right side. The circular turntable 811 and the fixed disc 812 form a rotational engagement. Three sets of hinged round rods 81 are evenly distributed around the top of the disc 812. Each set of hinged round rods has a fixed rod 815 mounted in the middle via a pin. The right side of the fixed rod is connected to a second set of hinged round rods 814. When the telescopic rod 810 moves horizontally, the circular turntable 811 drives the linkage mechanism to move synchronously, so that the three sets of fixed rods 815 form a circumferential clamping around the insulator blank 600. The clamping concentricity error is reduced, and the adaptive clamping design can be compatible with blanks of different diameters. There is no need to change the tooling when changing the type, and the adjustment time is shortened.

[0025] Example 3, as Figures 1-12The diagram illustrates a blank scraping device for insulator production. The inner wall of the rotating drum 714 is equipped with a lifting device 900 for raising and lowering the rotating disc 708. This device uses a screw drive principle to achieve fine-tuning of the cutting mechanism's height, adapting to the scraping requirements of insulator blanks 600 of different thicknesses. The lifting device 900 includes a rotating rod 903 that passes through and is rotatably connected to the inner wall of a handle 712. A rotating disc 902 is fixedly mounted on the top of the rotating rod 903, and a handle 901 is fixedly mounted on the top of the rotating disc 902. An outer rubber anti-slip sleeve is provided for the operator to apply rotational torque. A screw 904 is fixedly installed on the top of the rotating rod 903. A nut 905 is fitted on the lower side of the screw 904. A connecting rod 906 is fixedly installed on the outer side of the nut 905. A sliding block 907 is fixedly installed on the right side of the connecting rod 906. The sliding block 907 is embedded in a T-shaped slide rail pre-set on the inner wall of the hollow disc 710 to form a guiding constraint. The sliding block 907 is slidably connected to the inner wall of the hollow disc 710. The sliding block 907 is made of wear-resistant material.

[0026] In practical use, the operator can flexibly change the vertical height of the turntable 708 in the cutting assembly by adjusting the lifting device 900 on the top of the equipment. The operator needs to rotate the anti-slip handle 901 on the outer edge of the turntable 902 clockwise or counterclockwise according to the diameter of the insulator blank 600. By applying force with the hand, the operator drives the rotating rod 903 to rotate. The rotating rod 903 rotates through a trapezoidal screw 904 connected to the drive thread. Since the screw 904 and the nut 905 form a helical transmission, the rotational motion can be converted into a precise linear displacement of the nut 905 along the screw axis. The nut 905 is fixed on its outer wall. A connecting rod 906 is fixedly connected to the end of the connecting rod 906, and a sliding block 907 is fixedly connected to it. The sliding block 907 is embedded in a pre-set groove on the inner wall of the turntable 708. Through sliding engagement, when the nut 905 makes a vertical displacement on the screw 904, it will drive the sliding block 907 to slide up and down in the groove through the connecting rod 906. The precision screw drive reduces the error of manual operation, shortens the changeover adjustment time of blanks of different specifications, improves efficiency, extends the maintenance cycle of the mechanism, reduces workload, and improves the adaptability of working conditions. It effectively solves the limitation of traditional equipment that requires tooling replacement, improves overall production efficiency, and increases the finished product qualification rate.
