Description

Technical Field

[0001] This invention relates to the field of insulator production, and more particularly to a blank scraping device for the production of electrical insulators. Background Technology

[0002] Electrical insulators are generally made of ceramic or glass. When ceramic electrical insulators are manufactured, after the blank is dried, its surface needs to be scraped to obtain a flat and smooth surface. This is crucial for its final electrical performance, mechanical strength and long-term reliability. The scraping process mainly involves removing burrs and sprues from the surface.

[0003] However, existing devices are not conducive to maintaining the stability of the blank during scraping, resulting in poor scraping quality and making it difficult to intuitively understand whether the blank is placed in the center. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a blank scraping device for the production of electrical insulators that facilitates intuitive understanding of the centered placement of the blank and makes the blank scraping more stable and the scraping quality better.

[0005] The technical solution of the present invention is: a blank scraping device for the production of electrical insulators, comprising a base plate, a drive motor fixedly connected to the base plate, a turntable one and a turntable two provided on the base plate, both turntable one and turntable two being connected to the drive motor by a transmission assembly, a support platform one fixedly connected to turntable one, a support platform two fixedly connected to turntable two, an electric push rod one fixedly connected to the base plate, a tool holder slidably connected to the base plate, the tool holder being connected to the telescopic shaft of the electric push rod one, a guide rail fixedly connected to the base plate, a slider slidably connected to the guide rail, blanks being placed on both support platforms one and two, the two blanks being placed upside down, a tool selection mechanism provided on the slider, the tool selection mechanism being used to select different tools according to different parts of the blank, and a positioning mechanism provided on both turntable one and turntable two, the positioning mechanism being used to assist in the positioning of the blank.

[0006] Furthermore, the tool selection mechanism includes a support frame, which is fixedly connected to the slider. A support rod is rotatably connected to the support frame, and several placement racks are fixedly connected to the support rod. Each placement rack is connected to a fixing screw by a thread. A locking block is fixedly connected to one of the placement racks, and the locking block has several locking slots. A rotating handle is fixedly connected to the upper end of the support rod. A pull rod is slidably connected to the support frame, and one end of the pull rod is engaged in one of the locking slots on the locking block. A return spring is connected between the pull rod and the support frame.

[0007] Furthermore, the positioning mechanism includes several straight plates, which are fixedly connected to the inner walls of the first support platform and the second support platform. Each straight plate is slidably connected to a sliding frame, and a return spring connects the sliding frame to the straight plate. Each sliding frame has a rotatably connected swing pad at its upper end, and a torsion spring connects the swing pad to the sliding frame. A connecting ring connects the bottoms of the sliding frames on the same side, and side stops are fixedly connected to both sides of each connecting ring. Each side stop is slidably connected to... There is an inclined block, and a pressure spring is connected between the inclined block and the side stop bar. Four bent rods are fixedly connected to both the first turntable and the second turntable. Two bent rods are grouped together. A friction block is slidably connected between the two bent rods in each group. A screw is rotatably connected to each friction block. A wheel is fixedly connected to one end of each screw. The four screws are respectively threaded to the first turntable and the second turntable. A grooved plate is slidably connected to the middle of the first support platform. A support spring is connected between the grooved plate and the first turntable.

[0008] Furthermore, it also includes an indicating mechanism, which is mounted on the base plate. The indicating mechanism is used to indicate whether the blank is placed in the center. The indicating mechanism includes two drawing discs, which are respectively fixedly connected to the lower part of the first support platform and the second support platform. Two pillars are fixedly connected to the base plate. Each pillar has a rotating column rotatably connected to it. Several slots are opened on the side of the rotating column. A top rod is slidably connected to the side of each pillar. A limit spring is connected between the top rod and the pillar. One end of the top rod is located in a slot on the side of the rotating column. A stand is fixedly connected to each rotating column. A roller frame is slidably connected to each stand. A connecting spring is connected between the roller frame and the stand. A contact roller is rotatably connected to each roller frame. A marker pen is provided at the bottom of each roller frame. An erasing block is fixedly connected to the side of each stand. The erasing block contacts the surface of the drawing disc. A sloping baffle is fixedly connected to each erasing block. The sloping baffle contacts the surface of the drawing disc.

[0009] Furthermore, it also includes a suction mechanism, which is disposed on the second turntable. The suction mechanism is used to pull the blank downward. The suction mechanism includes a horizontal plate, which is fixedly connected to the inner wall of the second support platform. A piston tube is slidably connected to the horizontal plate. A suction cup is fixedly connected to the upper end of the piston tube. A piston rod is slidably connected inside the piston tube. A return spring is connected between the piston rod and the piston tube. A pulley is rotatably connected to the second turntable. Two guide plates are fixedly connected to the second turntable. A weight is slidably connected between the two guide plates. A connecting rope is connected between the weight and the piston rod. The connecting rope passes around the pulley.

[0010] The beneficial effects of the present invention are: 1. The side of the inclined block is in close contact with the side of the friction block, and the friction between the inclined block and the friction block will prevent the connecting ring and the sliding frame from resetting upward. This ensures that the swing pad block is less likely to shake or jump when it limits the support of the blank surface, making it more stable.

[0011] 2. When the drive motor is started and the placed blank is rotated, the upright frame is rotated first, causing the shaft roller frame and the contact roller to rotate together. This makes the contact roller contact the side of the rotating blank, and the top rod is engaged in another slot. After the shaft roller frame has rotated, the marker pen will contact the surface of the drawing plate. The drawing plate will rotate with the blank, and then the marker pen will leave a mark on the surface of the drawing plate. By observing the shaking amplitude of the mark, it is possible to determine whether the blank is placed in the center. This makes it more intuitive and convenient to determine whether the blank is centered.

[0012] 3. When the blank is placed on the support platform two with the protruding part facing upward, the inner surface of the blank will contact and squeeze the suction cup, making the piston tube sealed. Then, when the turntable two drives the blank to rotate, it will also drive the weight to rotate. Under the action of centrifugal force, the weight will move horizontally away from the axis of rotation, and then pull the piston rod downward through the connecting rope, thereby further increasing the suction force of the suction cup. This makes it less likely for the blank to be displaced due to the squeezing force generated by the tool scraping when processing the outer surface of the blank. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1 A blank scraping device for the production of electrical insulators, such as Figure 1-11As shown, the device includes a base plate 1, on which a drive motor 2 is fixedly connected. A turntable 3101 and a turntable 3102 are mounted on the base plate 1. Both turntables 3101 and 3102 are connected to the drive motor 2 via a transmission assembly 32. A support platform 3301 is fixedly connected to turntable 3101, and a support platform 3302 is fixedly connected to turntable 3102. An electric push rod 34 is fixedly connected to the base plate 1. A tool holder 35 is slidably connected to the base plate 1. 5 is connected to the telescopic shaft of the electric push rod 34. A guide rail 37 is fixedly connected to the base plate 1. A slider 38 is slidably connected to the guide rail 37. A blank 4 is placed on both the first support platform 3301 and the second support platform 3302. The two blanks 4 are placed upside down. A tool selection mechanism is provided on the slider 38. The tool selection mechanism is used to select different tools according to different parts of the blank 4. A positioning mechanism is provided on both the first turntable 3101 and the second turntable 3102. The positioning mechanism is used to help position the blank 4.

[0027] The tool selection mechanism includes a support frame 51, which is fixedly connected to the slider 38. A support rod 52 is rotatably connected to the support frame 51. Several placement racks 53 are fixedly connected to the support rod 52. Each placement rack 53 is connected to a fixing screw 54 by a thread. A locking block 55 is fixedly connected to one of the placement racks 53. The locking block 55 has several slots. A rotating handle 56 is fixedly connected to the upper end of the support rod 52. A pull rod 57 is slidably connected to the support frame 51. One end of the pull rod 57 is engaged in one of the slots on the locking block 55. A return spring 58 is connected between the pull rod 57 and the support frame 51.

[0028] The positioning mechanism includes several straight plates 61, which are fixedly connected to the inner walls of the first support platform 3301 and the second support platform 3302. Each straight plate 61 is slidably connected to a sliding frame 62, and a return spring 63 connects the sliding frame 62 to the straight plate 61. Each sliding frame 62 has a rotatably connected swing pad 64 at its upper end, and a torsion spring 65 connects the swing pad 64 to the sliding frame 62. A connecting ring 66 connects the bottom of the sliding frames 62 on the same side. Side stops 67 are fixedly connected to both sides of each connecting ring 66, and a slidable inclined block 68 is slidably connected below each side stop 67. A pressure spring 69 is connected between the side stops 67. Four bent rods 610 are fixedly connected to both the first turntable 3101 and the second turntable 3102. Two bent rods 610 form a group. A friction block 611 is slidably connected between the two bent rods 610 in each group. A screw 612 is rotatably connected to each friction block 611. A rotating wheel 613 is fixedly connected to one end of each screw 612. The four screws 612 are respectively threaded to the first turntable 3101 and the second turntable 3102. A grooved plate 614 is slidably connected to the middle of the first support platform 3301. A support spring 615 is connected between the grooved plate 614 and the first turntable 3101.

[0029] In the actual scraping of blank 4, the operator first places one blank 4 on support table 2 3302 with the protruding part facing upwards to perform outer surface scraping of blank 4; then places another blank 4 on support table 1 3301 with the protruding part facing downwards to perform inner surface scraping of blank 4. When blank 4 is placed, the swing pad 64 on support table 2 3302 will press against the inner surface of blank 4, and the swing pad 64 on support table 1 3301 will support and press against blank 4. The outer surface of the blank 4 is aligned with the protruding part of the grooved plate 614. When the blank 4 is placed, all the swing pads 64 are squeezed and adaptively deflected to fit the surface of the blank 4. The torsion spring 65 is twisted, and the swing pads 64 will drive the sliding frame 62 to move downward. The return spring 63 is stretched, which in turn drives the connecting ring 66 and the inclined block 68 to move downward together. The inclined block 68 is squeezed downward by the friction block 611 and moves horizontally a certain distance. The pressure spring 69 is stretched, so that the side of the inclined block 68 is pressed against the friction block 611. 11. The sides are in close contact, and the friction between the inclined block 68 and the friction block 611 will prevent the connecting ring 66 and the sliding frame 62 from returning to their original position. This ensures that the swing pad 64 is less prone to shaking or jumping when it provides limiting support for the surface of the blank 4, making it more stable. Then, different tools are fixed on the placement rack 53 by fixing screws 54. Since the surface of the blank 4 is mostly irregular, a blank 4 may require multiple tools for scraping. At this time, the pull rod 57 can be pulled out so that the pull rod 57 is no longer limiting the jamming block 55. Then, rotate handle 56 to change different cutting tools. After changing the cutting tools, start drive motor 2 to drive blank 4 to rotate. Then start electric push rod 1 34 and electric push rod 2 36 to drive the cutting tool to move and scrape the surface of blank 4. After scraping, swap the positions of the two blanks 4 to complete the surface scraping. After removing blank 4, rotate wheel 613 to drive screw 612 to rotate, so that friction block 611 moves horizontally and disengages from inclined block 68, allowing sliding frame 62 to return to its original position.

[0030] Example 2 Based on Example 1, such as Figure 7-8As shown, it also includes an indicating mechanism, which is mounted on the base plate 1. The indicating mechanism is used to indicate whether the blank 4 is centered. The indicating mechanism includes two drawing discs 71, which are respectively fixedly connected to the lower part of the first support platform 3301 and the second support platform 3302. Two support columns 72 are fixedly connected to the base plate 1. Each support column 72 is rotatably connected to a rotating column 73. The rotating column 73 has several slots on its side. Each support column 72 is slidably connected to a top rod 74 on its side. A limit spring 75 is connected between the top rod 74 and the support column 72. One end of the top rod 74 is located at the... In a slot on the side of each rotating column 73, a stand 76 is fixedly connected to each rotating column 73, a roller frame 77 is slidably connected to each stand 76, a connecting spring 78 is connected between the roller frame 77 and the stand 76, a contact roller 79 is rotatably connected to each roller frame 77, a marker pen 710 is provided at the lower part of each roller frame 77, an erasing block 711 is fixedly connected to the side of each stand 76, the erasing block 711 contacts the surface of the drawing plate 71, and a sloping baffle 712 is fixedly connected to each erasing block 711, the sloping baffle 712 contacts the surface of the drawing plate 71.

[0031] When the drive motor 2 is started to rotate the placed blank 4, the upright frame 76 is rotated first, causing the shaft roller frame 77 and the contact roller 79 to rotate together, so that the contact roller 79 contacts the side of the rotating blank 4, and the push rod 74 is engaged in another slot. After the shaft roller frame 77 has rotated, the marker pen 710 will contact the surface of the drawing plate 71. The drawing plate 71 will rotate together with the blank 4, and then the marker pen 710 will leave a mark on the surface of the drawing plate 71. By observing the shaking amplitude of the mark, it is possible to determine whether the blank 4 is placed in the center. This makes it more intuitive and convenient to determine whether the blank 4 is centered. After the upright frame 76 is rotated to reset, the erasing block 711 contacts the surface of the drawing plate 71 again. The continued rotation of the drawing plate 71 will cause the erasing block 711 to erase the mark on it. At the same time, the inclined baffle 712 can block the dust generated by scraping the blank 4 and prevent the erasing block 711 from being contaminated. Then the electric push rod 2 36 and electric push rod 1 34 are started.

[0032] Example 3 Based on Example 2, such as Figure 9-11As shown, it also includes a suction mechanism, which is disposed on the turntable 3102. The suction mechanism is used to pull the blank 4 downward. The suction mechanism includes a horizontal plate 81, which is fixedly connected to the inner wall of the support platform 3302. A piston tube 82 is slidably connected to the horizontal plate 81. A suction cup 83 is fixedly connected to the upper end of the piston tube 82. A piston rod 84 is slidably connected inside the piston tube 82. A return spring 85 is connected between the piston rod 84 and the piston tube 82. A pulley 86 is rotatably connected to the turntable 3102. Two guide plates 87 are fixedly connected to the turntable 3102. A weight 88 is slidably connected between the two guide plates 87. A connecting rope 89 is connected between the weight 88 and the piston rod 84. The connecting rope 89 passes around the pulley 86.

[0033] When the blank 4 is placed on the support platform 3302 with the protruding part facing upward, the inner surface of the blank 4 will contact and press the suction cup 83, making the piston tube 82 sealed. Then, when the turntable 3102 drives the blank 4 to rotate, it will also drive the weight 88 to rotate. The weight 88 will move horizontally away from the axis of rotation under the action of centrifugal force, and then pull the piston rod 84 downward through the connecting rope 89, thereby further increasing the suction force of the suction cup 83. This makes it less likely for the blank 4 to be displaced due to the squeezing force generated by the tool scraping when processing the outer surface of the blank 4.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
