[0001] This utility model relates to the technical field of ceramic forming equipment, specifically to a tool positioning device for an insulator trimming machine. Background Technology

[0002] Insulators are essential components that ensure the stable and safe transmission of electricity. Their primary function in electrical equipment and transmission lines is to support and isolate electrical conductors, bearing the dual responsibility of mechanical fixation and electrical insulation. In high-voltage circuits, insulators support the weight of the high-voltage line while simultaneously preventing direct contact between the line and the transmission tower, effectively preventing current from flowing to the ground through the tower, thus ensuring the reliability and safety of power transmission. The manufacturing process of insulators involves multiple stages, with the blanking process being a crucial step in ensuring the dimensional accuracy and surface quality of the insulators.

[0003] Existing insulator trimming machine tool positioning devices still have some problems. First, in terms of positioning accuracy, the structural design of traditional devices makes it difficult to achieve multi-point positioning and rapid adjustment of the insulator, and it is difficult to ensure the stable position of the insulator under different processing conditions. Second, in terms of tool adaptability, traditional devices have limited functionality and cannot meet the trimming needs of insulators of different specifications and shapes, thus limiting the versatility of the equipment. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a tool positioning device for an insulator trimming machine, comprising a clamping disc, a mounting base below the clamping disc, and a horizontal positioning component on the top of the clamping disc via a vertical plate. The horizontal positioning component includes two symmetrically arranged slides, each with a side clamping rod fixed to its adjacent sidewall. The end of each side clamping rod away from the slide is conical, and two threaded rods with opposite directions are connected to the two slides respectively. The adjacent end faces of the two threaded rods are fixed together, and the other end of the threaded rods is fixed to the clamping disc via a first fixing plate. A tool ring is rotatably connected to the outer circumference of the clamping disc, and a connecting plate is fixed to the top of the tool ring. A connecting plate is inserted through the connecting plate, and a tool plate is fixed to the end of the connecting plate near the slide. Multiple trimming blades are bolted to the sidewall of the tool plate, with the trimming blades positioned above the slide. Two fastening plates are fixed to the upper and lower sides of the connecting plate, and fastening screws for abutting the connecting plate are threaded onto the fastening plates. A rotating component for driving the tool ring to rotate is also provided.

[0005] Furthermore, the rotating component includes a geared motor mounted on the mounting base. The output end of the geared motor is connected to a drive rod. A first spur gear is fixed on the outer side of the drive rod. A driven rod rotatably connected to the mounting base is provided on the side of the drive rod. A second spur gear meshing with the first spur gear is fixed on the outer side of the driven rod. An internal hobbing gear is provided on the inner wall of the cutter ring. The second spur gear meshes with the internal hobbing gear.

[0006] Furthermore, the clamping plate is also provided with a top positioning component, which includes an inverted U-shaped top frame, a top clamping rod threadedly connected to the top frame, the bottom of the top clamping rod being conical, a second operating plate being fixed to the top of the top clamping rod, and a second rotating arm being fixed to the second operating plate.

[0007] Furthermore, an outer limiting ring is provided on the outer side of the tool ring, and the tool ring is rotatably connected to the outer limiting ring.

[0008] Furthermore, a guide rod is provided that passes through the two slides and is slidably connected to the slides. The guide rod is parallel to the lead screw, and both ends of the guide rod are fixed to the clamping plate through the second fixing plate.

[0010] Furthermore, a first operating disc is fixed to the outer side of one of the lead screws, and a first rotating arm is fixed to the first operating disc.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The three-point positioning design of the lateral and top positioning components enables the insulator to be positioned from multiple directions. The conical ends of the side and top clamping rods fit tightly together, and combined with the screw drive and thread adjustment, the position of the insulator is stably fixed, effectively reducing tool offset and wobbling during processing and improving the dimensional accuracy of the insulator blank.

[0013] 2. The device can flexibly adapt to the blanking needs of insulators with different outer diameter specifications by adjusting the positions of the transverse positioning component, the top positioning component, and the connecting plate.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Insulator blank trimming machine tool positioning device, such as Figure 1As shown, the device includes a clamping plate 1, with a mounting base 2 located below the clamping plate 1. The clamping plate 1 is fixed to the mounting base 2 via a vertical plate. A transverse positioning component is provided on the top of the clamping plate 1, comprising two symmetrically arranged slides 31. Side clamping rods 32 are fixed to the adjacent sidewalls of the two slides 31. The end of the side clamping rod 32 away from the slide 31 is conical and has two threaded screws 33 with opposite directions of rotation, which are respectively connected to the two slides 31. The two threaded screws 33 are adjacent to each other. The end faces are fixed, and the other end of the lead screw 33 is fixed to the clamping plate 1 through the first fixing plate 34. The outer side of one of the lead screws 33 is fixed with a first operating plate 35, and a first rotating arm 36 is fixed on the first operating plate 35. A guide rod 11 is provided, which passes through two slides 31 and is slidably connected to the slides 31. The guide rod 11 is parallel to the lead screw 33. The two ends of the guide rod 11 are fixed to the clamping plate 1 through the second fixing plate 12. The clamping plate 1 is provided with a sliding groove for the slides 31 to slide.

[0021] The mounting base 2 and the clamping plate 1 form a stable support. The lateral positioning component, through the cooperation of the lead screw 33, the slide table 31, and the side clamping rods 32, achieves lateral clamping and positioning of the insulator. The guide rod 11 and the slide groove ensure the smooth sliding of the slide table 31. The first operating plate 35 and the first rotating arm 36 facilitate manual driving of the lead screw 33. The insulator can be flexibly fixed laterally, and the spacing of the side clamping rods 32 can be adjusted by rotating the first rotating arm 36 to accommodate insulators of different sizes, providing a stable foundation for subsequent blank repair.

[0022] like Figure 1 As shown, in this embodiment, the clamping plate 1 is also provided with a top positioning component. The top positioning component includes a top frame 51 in the shape of an inverted U. A top clamping rod 52 is threadedly connected to the top frame 51. The bottom of the top clamping rod 52 is conical. A second operating plate 53 is fixed to the top of the top clamping rod 52. A second rotating rod 54 is fixed to the second operating plate 53.

[0023] The top clamping rod 52 is threaded to the top frame 51, and its vertical position can be adjusted by rotating the second rotating arm 54. In conjunction with the lateral positioning component, it achieves three-point fixation of the insulator from the top and side, forming an all-around clamping effect, enhancing the stability of the insulator during the blanking process and reducing swaying.

[0024] like Figure 1 and Figure 2As shown, in this embodiment, a tool ring 6 is rotatably connected to the outer periphery of the fixture disk 1. An outer limiting ring 14 is provided on the outer side of the tool ring 6. The tool ring 6 is rotatably connected to the outer limiting ring 14. A connecting plate 7 is fixed to the top of the tool ring 6. A connecting plate is inserted through the connecting plate 7. A tool plate 13 is fixed to one end of the connecting plate 7 near the slide table 31. Multiple trimming blades 8 are connected to the side wall of the tool plate 13 by bolts. The trimming blades 8 are located above the slide table 31. Two fastening plates 9 are fixed to the upper and lower sides of the connecting plate 7. Fastening screws 10 for abutting the connecting plate are threaded on the fastening plates 9. A rotating component for driving the tool ring 6 to rotate is provided.

[0025] The tool ring 6 is rotatably connected to the outer periphery of the clamping disk 1, and the outer limiting ring 14 ensures its rotational stability. The combination of components such as the connecting plate 7, the connecting plate, the tool plate 13, and the fastening plate 9 realizes the installation and position fixation of the trimming blade 8, providing a reliable installation carrier for the trimming blade 8. The tool position can be adjusted by the fastening screw 10 to ensure that the tool trims the insulator in the appropriate position, meeting the trimming process requirements of insulators with different outer diameters.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the rotating component includes a geared motor 41 mounted on the mounting base 2. The output end of the geared motor 41 is connected to a drive rod 42. A first spur gear 43 is fixed on the outer side of the drive rod 42. A driven rod 44 rotatably connected to the mounting base 2 is provided on the side of the drive rod 42. A second spur gear 45 that meshes with the first spur gear 43 is fixed on the outer side of the driven rod 44. An internal hobbing gear 46 is provided on the inner wall of the cutter ring 6. The second spur gear 45 meshes with the internal hobbing gear 46.

[0027] The geared motor 41 serves as the power source, and its rotation is achieved through the meshing of the drive rod 42, the first spur gear 43, the driven rod 44, the second spur gear 45, and the inner hobbing gear 46 on the inner wall of the tool ring 6. This provides stable rotational power to the trimming blade 8. The speed of the tool ring 6 can be controlled by the geared motor 41, allowing the trimming blade 8 to process the insulator at a suitable speed, improving trimming efficiency and quality, and ensuring a stable and reliable transmission structure.

[0028] The working principle of this utility model is as follows:

[0029] Lateral positioning of the insulator: The operator rotates the first rotating arm 36 on the first operating disc 35. Since the two lead screws 33 have opposite threads and one end is fixed together, rotating the first rotating arm 36 will drive the two lead screws 33 to rotate. The rotation of the lead screws 33 drives the two slides 31 to move towards each other in the grooves of the clamping disc 1. As the slides 31 move, the side clamping rods 32 fixed to the side walls of the slides 31 also move. When the slides 31 move to the appropriate position, the conical ends of the side clamping rods 32 can accurately clamp the bottom sides of the insulator, thereby achieving lateral positioning of the insulator. The guide rod 11 provides stable guidance for the slides 31 during this process, ensuring the stability of the movement of the slides 31.

[0030] Insulator top positioning: The operator rotates the second rotating arm 54 on the second operating disc 53. The second rotating arm 54 drives the top clamping rod 52 to rotate on the top frame 51. Since the top clamping rod 52 is threadedly connected to the top frame 51, rotating the top clamping rod 52 will cause it to move up and down along the thread. When the top clamping rod 52 moves downward, its conical bottom gradually approaches the top of the coil until it abuts the insulator, thus achieving vertical positioning and fixation of the insulator, and cooperating with the lateral positioning component to achieve three-point positioning.

[0031] Tool position adjustment: If the tool position needs to be adjusted during processing, the operator can loosen the fastening screws 10 on the fastening plate 9 to allow the connecting plate to move on the connecting plate 7. After adjusting the positions of the tool plate 13 and the trimming insert 8, tighten the fastening screws 10 again, and use the fastening plate 9 to press against the connecting plate to re-fix the tool position.

[0032] Tool rotation drive: The geared motor 41 is started, and the output end of the geared motor 41 drives the drive rod 42 to rotate. The first spur gear 43 on the outer side of the drive rod 42 rotates together with the drive rod 42. The first spur gear 43 meshes with the second spur gear 45 on the outer side of the driven rod 44, thereby transmitting power to the driven rod 44 and causing the driven rod 44 to rotate. The second spur gear 45 on the driven rod 44 meshes with the internal hobbing gear 46 on the inner wall of the tool ring 6, thereby driving the tool ring 6 to rotate around the outer circumference of the fixture disk 1. The rotation of the tool ring 6 drives the connecting plate 7, the tool plate 13, and the trimming blade 8 fixed on its top to rotate together, realizing the trimming process of the insulator.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
