Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and specifically to a polishing device. Background Technology

[0002] After casting, the copper busbar of the current transformer will have resin, oil, and burrs and flash from the manufacturing process on its surface, all of which will affect the subsequent assembly of the copper busbar. Current methods for handling this include: First, milling on a milling machine. This requires placing the product on the milling machine, clamping it with tools, and then milling with a milling cutter. This method is inefficient and complex. Second, using a manual grinder. First, coarse sandpaper is used, then fine sandpaper is used. During the grinding process, the grinder needs to apply vertical downward pressure to the surface of the device being ground. Because the grinder operator cannot maintain this vertical downward pressure for extended periods, the grinder is prone to tilting, scratching the surface to be ground and the current transformer, easily resulting in an uneven surface. Utility Model Content

[0017] In a further optimization, the fixed-distance pushing structure is laterally slidably mounted on the support plate via a position adjustment component.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0035] Example 1

[0036] This embodiment 1 provides a grinding device, such as... Figures 1-2 As shown, it includes:

[0037] Grinding mechanism 1 is used to grind the object to be ground;

[0038] A fixed-distance pushing structure 2 is located on the grinding mechanism 1 and is used to push the grinding mechanism 1 so that the sanding belt 13 fits against the surface to be ground.

[0039] Adjustment mechanism 3, which is connected to grinding mechanism 1, is used to drive grinding mechanism 1 to move towards or away from the grinding station.

[0040] In this embodiment, the grinding equipment is used to grind the copper busbars on the current transformer; that is, the surface to be ground is the surface of the copper busbars. Specifically, the grinding mechanism 1 is positioned above the current transformer, with the copper busbars protruding above the top surface of the current transformer, i.e., 3mm higher during casting. Therefore, when the grinding mechanism 1 falls, it will not cause wear to other parts of the current transformer.

[0041] The specific working process is as follows: During grinding, the grinding mechanism 1 is brought closer to the grinding station by adjusting the adjustment mechanism 3. At this time, the grinding mechanism 1 is in contact with the copper busbar of the current transformer. Then, the fixed-distance pushing mechanism moves downward to ensure effective contact between the grinding mechanism 1 and the surface to be ground. This ensures the effective grinding amount of the grinding mechanism 1.

[0042] In addition, the grinding amount of the copper busbar can be controlled by controlling the moving distance of the fixed-distance pushing mechanism, thereby improving the grinding efficiency and accuracy of the workers and ultimately ensuring the normal use of the transformer.

[0043] The grinding equipment in this solution is not limited to the grinding of copper busbars in current transformers. In addition, it can be used in any field where grinding technology is applicable, such as steel manufacturing.

[0044] Furthermore, the grinding mechanism 1 includes a support plate 11, a rotating roller 12, and a sanding belt 13.

[0045] The support plate 11 is fixedly connected to the connecting block 8;

[0046] At least two rotating rollers 12 are provided, and multiple rotating rollers 12 are rotatably mounted on the support plate 11;

[0047] The sanding belt 13 is sleeved on multiple rotating rollers 12, and the side of the sanding belt 13 that is in contact with the surface to be sanded forms a horizontal surface and is used to contact the surface to be sanded.

[0048] The specific working process of the grinding mechanism 1 in this embodiment is as follows: the support plate 11 is used to support the rotating roller 12 and the sanding belt 13, ensuring the normal rotation of the rotating roller 12 and the normal movement of the sanding belt 13.

[0049] In this embodiment, three rotating rollers 12 are arranged in a triangle. The sanding belt 13 is wound around the three rotating rollers 12. The three rotating rollers 12 rotate, driving the sanding belt 13 to move. This process is similar to the principle of belt conveyor. Finally, the sanding belt 13 is in contact with the surface to be sanded for grinding.

[0050] It is known that the number of rotating rollers 12 is not limited, and can be two, four or more. Most importantly, the sanding belt 13 is wound around the rotating rollers 12 and moves, and it is necessary to ensure that the side of the sanding belt 13 in contact with the part to be sanded is horizontal to ensure the flatness of the grinding surface.

[0051] The fixed-distance pushing structure 2 is laterally slidably mounted on the support plate 11 via the position adjustment component 6. Specifically, the position adjustment component 6 can align the fixed-distance pushing structure 2 with the copper busbar, allowing the fixed-distance pushing structure 2 to drive the abrasive belt 13 to ensure contact grinding with the copper busbar. Specifically, the contact surface between the abrasive belt 13 and the fixed-distance pushing structure 2 is a smooth surface, and the operation of the fixed-distance pushing structure 2 does not affect the movement of the abrasive belt 13.

[0052] The grinding mechanism 1 is equipped with at least one fixed-distance pushing structure 2, and there can be multiple fixed-distance pushing structures 2, all of which are slidably mounted on the support plate 11. Specifically, some current transformers have more than one copper busbar, and there is a certain distance between the copper busbars. In order to ensure stable grinding of each copper busbar on the current transformer, this embodiment sets two positioning pushing structures to grind different copper busbars separately, thereby improving the grinding efficiency. In addition, it should be noted that the number of positioning pushing structures can be set according to the number and spacing of the copper busbars to be ground, and is not limited to two.

[0053] Specifically, each of the fixed-distance pushing structures 2 includes a slider 21, a cylinder 22, and a pressure plate 23. Specifically, the slider 21, the cylinder 22, and the pressure plate 23 are all located inside the sanding belt 13.

[0054] The slider 21 is slidably mounted on the support plate 11. The specific sliding cooperation between the support plate 11 and the slider 21 can be: guide rail slider 21 cooperation, groove slider 21 cooperation (the groove can also be a dovetail groove, positioning groove, or other groove that can guide the slider 21), etc.

[0055] The slider 21 is connected to the position adjustment component 6 and is used to limit and fix the slider 21.

[0056] The cylinder 22 is located at the bottom of the slider 21. In this embodiment, the cylinder 22 is used to drive the pressure plate 23 to move. The cylinder 22 can also be replaced by a hydraulic cylinder, an electric telescopic rod or other telescopic structure to ensure a certain amount of displacement of the pressure plate 23.

[0057] The pressure plate 23 is located at the telescopic end of the cylinder 22 and is used to abut against the sanding belt 13.

[0058] The working process of the positioning and pushing mechanism in this embodiment is as follows:

[0059] Drive cylinder 22, pressure plate 23 moves downward to fit against one side of sanding belt 13, then cylinder 22 continues to move downward a certain amount to contact sanding belt 13 until sanding belt 13 contacts the surface of copper busbar for grinding. Since the final grinding thickness of coarse and fine grinding does not exceed 0.5mm, the extension and retraction of cylinder 22 needs to be precisely controlled to ensure that the grinding amount of sanding belt 13 is within the normal range.

[0060] Furthermore, the position adjustment component 6 is a bolt assembly. Specifically, the support plate 11 is provided with a limiting hole, and the slider 21 is provided with a through hole to ensure that the bolt passes through and engages with the threaded limit hole, so as to ensure that the slider 21 is fixedly connected to the support plate 11.

[0061] Example 2

[0062] like Figure 1As shown, to ensure the smoothness and flatness of the copper busbars on the current transformer after polishing, this embodiment is configured with two polishing mechanisms 1. These two polishing mechanisms 1 are connected to the adjusting mechanism 3 via a connecting block 8, and are used to perform coarse and fine polishing processes on the device to be polished, respectively. Specifically, when the device to be polished is coarsely polished, the abrasive belt 13 is a coarse abrasive belt 13; when the device to be polished is finely polished, the abrasive belt 13 is a fine abrasive belt 13.

[0063] The working process is as follows: the device to be polished is first coarsely polished and then finely polished. Two polishing mechanisms 1 are arranged along the conveying direction of the transformer, and thus two polishing stations are set up.

[0064] Furthermore, the adjustment mechanism 3 includes a support frame 31, a lead screw 32, a limiting rod 33, and a reduction motor 34.

[0065] The lead screw 32 is rotatably mounted on the support frame 31, and the lead screw 32 is threadedly connected to the connecting block 8.

[0066] The limiting rod 33 is fixedly installed on the support frame 31, and the limiting rod 33 is slidably connected to the connecting block 8;

[0067] The geared motor 34 is installed at one end of the lead screw 32 and is used to drive the lead screw 32 to rotate.

[0068] Specifically, the working process of the regulating mechanism 3 is as follows:

[0069] In this embodiment, the adjusting mechanism 3 is used to adjust the height of the polishing mechanism 1, thereby ensuring that the bottom surface of the polishing mechanism 1 can fit in contact with the polishing surface of the transformer copper busbar during polishing. The support frame 31 supports the entire polishing mechanism 1, and the lead screw 32 and connecting block 8 cooperate to drive the movement of the polishing mechanism 1.

[0070] Specifically, the geared motor 34 is started, which drives the lead screw 32 to rotate. With the threaded engagement between the lead screw 32 and the connecting block 8, and with the limiting position of the connecting block 8 by the limiting rod 33, the connecting block 8 moves vertically downward to drive the polishing mechanism 1 to move downward and finally fit into the copper busbar.

[0071] Conversely, when the geared motor 34 is started in reverse, the geared motor 34 drives the lead screw 32 to rotate in the opposite direction. With the threaded engagement between the lead screw 32 and the connecting block 8, and with the limiting position of the connecting block 8 by the limiting rod 33, the connecting block 8 moves vertically upward to drive the polishing mechanism 1 to move upward away from the copper busbar.

[0072] Example 3

[0073] This embodiment provides a grinding device, which further includes a conveying mechanism 4 located below the grinding mechanism 1 and used to convey the device to be ground.

[0074] The conveying mechanism 4 is a roller conveyor, chain conveyor, roller conveyor, speed-up line or belt conveyor.

[0075] Furthermore, it also includes a positioning mechanism 5, which is used to push the grinding device away from the conveying mechanism 4 and position the device to be ground.

[0076] When the conveying mechanism 4 has a clearance space, the positioning mechanism 5 is located below the conveying mechanism 4. During operation, the positioning mechanism 5 passes through the clearance space to push the device to be polished away from the conveying mechanism 4 and position it.

[0077] The positioning mechanism 5 includes a first telescopic member, a first support plate, and a first abutment. In this embodiment, the first support plate is used to support and drive the first abutment to move up and down, the first telescopic member is used to drive the positioning mechanism 5 to move, and the first abutment is used to contact the current transformer to lift it up.

[0078] The telescopic end of the first telescopic member is fixedly connected to the first support plate;

[0079] The first abutment is mounted on the first support plate to stably lift the device to be polished. Multiple first abutments are evenly distributed on the first support plate; in this embodiment, four first abutments are provided, positioned directly below the clearance space. The other four first abutments abut against the four sides of the bottom of the current transformer to ensure its balance. It is understood that the number of first abutments is not limited to four; it can also be two, six, or eight, depending on the specific size of the current transformer. Furthermore, the first abutments have guide and limiting surfaces, thus supporting, positioning, and lifting the current transformer.

[0080] In addition, the positioning mechanism 5 may also include a first positioning member and a second positioning member. The first positioning member and the second positioning member are respectively placed on both sides of the conveying direction of the conveying mechanism 4. When the conveying mechanism 4 conveys the device to be polished to the polishing station, the first positioning member and the second positioning member cooperate to push the device to be polished away from the conveying mechanism 4 and position it.

[0081] Both the first and second positioning components include a second telescopic component, a second support plate, and a second stop rod.

[0082] The telescopic end of the second telescopic component is fixedly connected to the second support plate;

[0083] The second abutment is mounted on the second support plate to smoothly lift the device to be polished. There can be one, two, or more second abutments. When multiple abutments are used, they are arranged side by side and ultimately abut against one side of the current transformer.

[0084] In addition, the second telescopic member is one of a cylinder, a telescopic rod, and a hydraulic rod. It is understood that this embodiment is not limited to the above forms. Any structure that can lift the device to be polished is included in the second telescopic member.

[0085] When the bottom area of ​​the current transformer is greater than or equal to the transmission area of ​​the conveying mechanism 4, the second abutment rods on the two positioning parts cooperate to abut against the corresponding side of the bottom of the current transformer for lifting.

[0086] When the bottom area of ​​the current transformer is smaller than the transmission area of ​​the conveying mechanism 4, connecting blocks 8 can be set on both sides of the current transformer and extend out of the range of the conveying mechanism 4. Then, the second abutment rods on the first positioning member and the second positioning member extend out and cooperate with the connecting blocks 8 to achieve lifting.

[0087] Furthermore, it also includes a collection component 7, which is installed on the support plate 11 to collect copper shavings that fall off during polishing, facilitating subsequent processing.

[0088] Since the sanding belt 13 moves at a certain speed, when grinding the copper busbar, copper shavings will be scattered along the rotation direction of the sanding belt 13. At this time, a collection component 7 is set on the support plate 11. The copper shavings enter the collection component 7, which ensures the cleanliness of the grinding environment and allows the collected copper shavings to be recycled, thus improving the utilization rate of resources.

[0089] Specifically, the collecting component 7 is a collecting cylinder, and the shape of the collecting cylinder is as follows: Figure 2 As shown, the collecting cylinder has an opening on one side, and the copper filings enter the cylinder and then pass through a guide side to the bottom. This facilitates the stable collection of copper filings.

[0090] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
