Description

Technical Field

[0001] This utility model belongs to the field of insulating gasket processing technology, specifically relating to an insulating kit polishing processing device. Background Technology

[0002] Currently, insulating gaskets, as common components in electrical equipment and mechanical structures, require polishing during production to ensure surface flatness and dimensional accuracy, thereby improving insulation performance and assembly stability. Existing polishing methods for insulating gaskets mainly rely on manual operation or simple grinding equipment, typically involving manually fixing the gasket and polishing with sandpaper or abrasive wheels. This method suffers from low operational efficiency and poor processing accuracy, and in batch processing, it easily leads to uneven polishing of the gasket surface, affecting subsequent use.

[0003] In actual processing, although some equipment uses belt abrasive mechanisms for automated polishing, the single method of fixing the shims, often relying on clamps for clamping, can easily lead to unstable clamping or positioning misalignment when the shims are small or irregularly shaped, resulting in insufficient polishing accuracy. Furthermore, the abrasive belt tends to loosen over long-term use; if it is not kept taut in time, uneven polishing or slippage can occur, affecting the overall processing quality. In addition, some devices lack adjustment functions for shims of different thicknesses or specifications when polishing multiple parts simultaneously, limiting the equipment's applicability and increasing production costs.

[0004] In summary, existing insulating gasket polishing equipment generally suffers from the following technical problems: First, the lack of an efficient and reliable fixing mechanism makes the gaskets prone to displacement during polishing, affecting polishing accuracy; second, the abrasive belt tensioning and adjustment structure is imperfect, failing to ensure that the abrasive belt is always in a stable working state, thus affecting processing uniformity; and third, the lack of flexible adjustment functions for insulating gaskets of different sizes and thicknesses results in insufficient processing adaptability, limiting its application in mass production.

[0019] This invention, by setting a vacuum suction cup on the surface of the skateboard and arranging a placement groove on the surface of the suction cup, can firmly adsorb and position the insulating pad before polishing, avoiding the problems of unstable clamping and easy displacement of the pad in the prior art, thereby ensuring the stability and accuracy of the polishing process.

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0031] Example 1:

[0032] like Figures 1-6 As shown, an insulating kit polishing device includes a worktable 1. Slide rails 11 are provided on both sides of the upper surface of the worktable 1. A slide plate 3 is slidably installed between the two slide rails 11. A vacuum suction cup 31 is provided on the upper surface of the slide plate 3. Suction holes are evenly distributed on the surface of the vacuum suction cup 31, and these holes are connected to channels on the slide plate 3 to generate negative pressure airflow to adsorb and fix multiple insulating pads. A placement groove can also be provided on the vacuum suction cup 31 to limit and position the edges of the insulating pads, preventing displacement during polishing. An air pump can be installed below the worktable 1, connected to the vacuum suction cup 31 via a pipeline to ensure stable adsorption force, thereby improving the reliability of the insulating pad fixation and the uniformity of polishing.

[0033] Side plates 2 are symmetrically arranged on both sides of the upper surface of the workbench 1. The two side plates 2 are placed outside the slide rail 11. A first roller shaft 41, a second roller shaft 42, and a third roller shaft 43 are rotatably installed between the two side plates 2, and the three roller shafts are distributed in a triangle. The first roller shaft 41 is located at the top, the second roller shaft 42 is located at the bottom and close to the longitudinal slide groove 22, and the third roller shaft 43 is located at the bottom and close to the transverse slide groove 21. The relative arrangement of the three roller shafts can form a stable running path for the sandpaper belt 10. The side plates 2 are fixedly connected to the workbench 1 by bolts to ensure the rigidity and stability of the overall structure.

[0034] The three rollers have the same structure and uniformly opened annular grooves 44 on their surfaces. A sandpaper belt 10 is fitted between the three corresponding annular grooves 44. The sandpaper belt 10 is made of wear-resistant abrasive cloth and is kept taut by a tensioning structure. The position of the sandpaper belt 10 corresponds to the position of the suction holes in the same row as the vacuum suction cup 31, so as to ensure that the sandpaper belt 10 can cover the upper surface of the insulating pad one by one when it moves, thereby realizing the polishing process. During long-term operation, the sandpaper belt 10 can avoid slack due to the above-mentioned tensioning mechanism, thereby improving the polishing uniformity and processing quality.

[0035] like Figure 2 and Figure 4 As shown, a horizontal sliding groove 21 is provided on the rear side of the side plate 2 surface, and the horizontal sliding groove 21 extends in the horizontal direction. A vertical sliding groove 22 is provided on the lower side of the side plate 2 surface, and the vertical sliding groove 22 extends in the vertical direction. The first roller shaft 41 is placed directly above the vertical sliding groove 22. One end of the first roller shaft 41 is mounted on a motor. The motor is connected to the first roller shaft 41 through a coupling and is used to drive the first roller shaft 41 to rotate, thereby driving the sandpaper belt 10 to circulate and ensure the continuity and efficiency of the polishing work.

[0036] like Figures 1-5As shown, a horizontal slider 5 is slidably installed inside the horizontal slide groove 21. The horizontal slider 5 and the horizontal slide groove 21 are in sliding fit. The two ends of the third roller shaft 43 are respectively rotatably installed on the two horizontal sliders 5. The horizontal sliders 5 can move back and forth in the horizontal slide groove 21 to adjust the position of the third roller shaft 43. A spring 6 is provided on the front side inside the horizontal slide groove 21. The spring 6 applies a backward thrust to the horizontal slider 5, so that the third roller shaft 43 can always maintain a taut state when driven by the longitudinal slider 7, thereby ensuring the stability of the sandpaper belt 10.

[0037] like Figures 1-5 As shown, a longitudinal slider 7 is slidably installed inside the longitudinal groove 22. The longitudinal slider 7 and the longitudinal groove 22 are vertically slidably fitted. The two ends of the second roller shaft 42 are respectively rotatably installed on the longitudinal slider 7. The up and down movement of the longitudinal slider 7 can drive the height change of the second roller shaft 42, thereby adjusting according to the thickness of the insulating pad, so as to achieve reasonable contact between the sandpaper belt 10 and the pad, and improve the polishing adaptability.

[0038] like Figure 2 and Figure 6 As shown, a rotating shaft 8 is rotatably installed between the two side plates 2. The rotating shaft 8 is positioned directly above the second roller shaft 42. The rotating shaft 8 is rotatably connected to the side plates 2 through bearings to ensure rotational flexibility. An arc-shaped protrusion 71 is provided on the upper surface of the longitudinal slider 7. The arc-shaped protrusion 71 contacts the extrusion rod 81 on the rotating shaft 8 to realize the up and down movement control of the longitudinal slider 7.

[0039] like Figure 2 and Figure 6 As shown, the rotating shaft 8 is symmetrically provided with pressing rods 81. The two pressing rods 81 are in contact with the two arc-shaped protrusions 71 respectively. One end of the rotating shaft 8 passes through the side plate 2. The end of the rotating shaft 8 is provided with a gear 82. The gear 82 achieves the rotation control of the rotating shaft 8 by meshing with the rack 9, thereby driving the pressing rods 81 to press or release the arc-shaped protrusions 71, so as to control the vertical movement of the longitudinal slider 7 in the longitudinal slide groove 22.

[0040] like Figure 2 and Figure 6 As shown, two protruding plates 23 are provided on the outer side of one of the side plates 2. Threaded rods 24 are horizontally rotatably mounted on the two protruding plates 23. The threaded rods 24 are supported on the protruding plates 23 by bearings. A toothed rod 9 is screwed onto the surface of the threaded rod 24. The toothed rod 9 is positioned above the gear 82 and meshes with the gear 82. When the threaded rod 24 rotates, it can drive the toothed rod 9 to move laterally, thereby controlling the rotation angle of the rotating shaft 8 and ultimately adjusting the height of the longitudinal slider 7 to ensure stable and reliable contact pressure between the sandpaper belt 10 and the insulating gasket.

[0041] Example 2:

[0042] See Figures 1-6When an insulating kit polishing processing device is in operation, the insulating pad to be processed is first placed on the vacuum suction cup 31 on the upper surface of the slide plate 3. The vacuum suction cup 31 generates a negative pressure airflow through a vacuum pump connected to a pipeline via a suction hole, which adsorbs and fixes the insulating pad. When the insulating pad is small, the insulating pad can be limited and positioned by the placement groove set on the surface of the vacuum suction cup 31 to ensure that the insulating pad does not shift during the polishing process. The slide plate 3 slides horizontally on the slide rail 11. The pushing method can be either manual direct pushing or automated movement by installing a linear drive device or a linear motor to achieve batch processing.

[0043] During the polishing process, the first roller 41 is driven to rotate by a motor, which is connected to the first roller 41 through a coupling to ensure smooth transmission. The surfaces of the first roller 41, the second roller 42, and the third roller 43 are evenly distributed with annular grooves 44. The sandpaper belt 10 is fitted between the corresponding annular grooves 44. The triangular distribution of the three rollers allows the sandpaper belt 10 to maintain a stable circulation path. Driven by the motor, the sandpaper belt 10 moves continuously around the three rollers, and its surface is in close contact with the insulating pad, thereby achieving the polishing process.

[0044] The second roller shaft 42 is mounted on the longitudinal slider 7 at both ends. The longitudinal slider 7 slides vertically within the longitudinal groove 22. The position of the second roller shaft 42 can be changed by adjusting the height of the longitudinal slider 7 to accommodate insulating gaskets of different thicknesses. The arc-shaped protrusion 71 on the upper surface of the longitudinal slider 7 contacts the extrusion rod 81 on the rotating shaft 8. When the rotating shaft 8 rotates via the gear 82, the extrusion rod 81 presses against the arc-shaped protrusion 71, causing the longitudinal slider 7 to move downward within the longitudinal groove 22, thereby driving the second roller shaft 42 to descend. The sandpaper belt 10 exerts a certain pressure on the insulating gasket. When the rotating shaft 8 rotates in the opposite direction, the extrusion rod 81 releases the pressure on the arc-shaped protrusion 71, and the longitudinal slider 7 moves upward under the reaction force of the spring 6. The second roller shaft 42 rises accordingly, thereby releasing the pressure between the sandpaper belt 10 and the insulating gasket, achieving pressure regulation.

[0045] The third roller shaft 43 is mounted on the horizontal slider 5 at both ends. The horizontal slider 5 slides back and forth in the horizontal slide groove 21. The spring 6 is fixed to the front end of the horizontal slide groove 21 and applies a backward thrust to the horizontal slider 5 to ensure that the third roller shaft 43 always applies tension to the sandpaper belt 10 so that the sandpaper belt 10 will not loosen during operation. The travel of the horizontal slider 5 is limited by the length of the horizontal slide groove 21 to ensure that the third roller shaft 43 runs smoothly.

[0046] Throughout the operation, the threaded rod 24 is horizontally installed between the protruding plates 23 on the outer side of the side plate 2. The threaded rod 24 is supported by the rotation of the bearing. The surface of the threaded rod 24 is engaged with the toothed rod 9, which meshes with the gear 82. When the threaded rod 24 rotates, the toothed rod 9 moves in the horizontal direction and drives the gear 82 to rotate, thereby controlling the rotation angle of the rotating shaft 8 and realizing the precise adjustment of the height of the longitudinal slider 7. Since the threaded rod 24 has a self-locking function, it can effectively prevent the longitudinal slider 7 from being displaced by external forces, thereby ensuring stable polishing pressure.

[0047] As the sliding plate 3 moves the insulating pads, the sandpaper belt 10 will contact the surface of the insulating pads in the same row in turn and polish each insulating pad evenly. Since the sandpaper belt 10 only processes one row of insulating pads, the utilization rate of the sandpaper belt 10 is improved, avoiding large-area consumption and reducing the cost of use. At the same time, the sliding plate 3 can move back and forth repeatedly to achieve multiple polishing processes to meet different polishing precision requirements.

[0048] Through the coordinated operation of the above structures, the device can not only ensure the stable fixation of the insulating gasket during the polishing process, but also achieve continuous tension and pressure adjustment of the sandpaper belt 10. This overcomes the problems of unstable clamping, loose sandpaper belt and poor thickness adaptability in the prior art, thereby improving the processing efficiency and quality of insulating gasket polishing. It is suitable for the production of insulating kits of different specifications and in batches.

[0049] The working principle of this utility model is as follows: First, the insulating pad to be polished is placed on the surface of the vacuum suction cup 31. The pad is adsorbed and fixed by the vacuum suction cup 31. Alternatively, a groove for limiting the placement of the pad can be opened on the surface of the vacuum suction cup 31. When no force is applied, the spring 6 applies a backward pushing force to the horizontal slider 5, so that the horizontal slider 5 is placed inside the rear of the horizontal sliding groove 21. At this time, the third roller shaft 43 is placed at the last side of the stroke and pulls the vertical slider 7 upward, so that the arc-shaped protrusion 71 always maintains contact with the extrusion rod 81. At this time, the sandpaper belt 10 remains taut.

[0050] Adjust the height of the second roller shaft 42 according to the thickness of the pad to be polished. Control the lateral movement of the rack 9 by rotating the threaded rod 24. The rotation of the shaft 8 can be controlled by the meshing of the rack 9 and the gear 82. Then, the longitudinal slider 7 moves down inside the longitudinal groove 22 by the squeezing rod 81 on the arc protrusion 71. At this time, the horizontal slider 5 can be moved forward by the sandpaper belt 10, or the squeezing can be released to move the slider 7 up to expand the space below. During this process, the sandpaper belt 10 is kept taut. The self-locking property of the threaded rod 24 is used to keep the height of the longitudinal slider 7 fixed and push the slide plate 3 to move. Since the positions of the suction holes in the same row on the slide plate 3 correspond to the positions of the multiple sandpaper belts 10, the insulating pads in this row can be polished by the sandpaper belts 10 when moving. The movement of the slide plate 3 can be manually pushed or controlled by a linear motor.

[0051] This device can polish insulating gaskets of different sizes, and a single sandpaper belt 10 can process a single row of insulating gaskets, thereby reducing the amount of sandpaper belt 10 used and thus reducing the cost of use.

[0052] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
