Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of polishing device, concretely relates to a switchgear door corner polishing device. BACKGROUND

[0002] The main role of the switch cabinet is to open and close, control and protect the electrical equipment in the power system, and the cabinet body and the cabinet door of the switch cabinet are generally made of metal materials. During the preparation of the switch cabinet, an edge corner polishing device is needed to polish the edges and corners of the switch cabinet, thereby facilitating subsequent spraying processing of the switch cabinet.

[0003] However, in the use process of the existing edge corner polishing device, the polishing disc of the polishing device is prone to unintended axial movement under the action of external force, causing uneven polishing of the edge corner in contact with the polishing disc, and even unintended damage.

[0004] The polishing device in the prior art often has unintended axial deviation of the polishing wheel during polishing. For example, see the patent application CN219704655U published on September 19, 2023, with the publication number CN219704655U, which states in the specification

[0003] that "since the grinding wheel is always in a high-speed rotating state during work, the existing flange assembly structure will cause the grinding wheel to be fixed after installation, and long-time operation will cause the connection to loosen, resulting in axial deviation of the grinding wheel, even loosening and falling off, etc. problems, thereby reducing the processing precision of the grinding wheel and causing product quality defects", and see the patent application CN221186042U published on June 21, 2024, with the publication number CN221186042U, which states in the specification

[0003] that "during the grinding process, since the support rod is uniformly arranged below the axis of the grinding disc on the machine body, the upper grinding disc is more evenly compressed by the correction device. When the upper grinding disc deviates, the correction device in the deviation direction of the upper grinding disc is compressed, the upper grinding disc is subjected to a force opposite to its movement direction, causing the upper grinding disc to return to the center position, reducing the occurrence of upper grinding disc misalignment, and improving the grinding efficiency".

[0005] On this basis, the limiting action is realized through the threaded rod device, which is a common way in the current polishing field. For example, please refer to the patent application for a convenient single-operation table for polishing based on shell sheet metal, which was published on November 13, 2020 and has a publication number CN211916517U. In the specification

[0028] section, it is recorded that "the worker rotates the limiting screw rod 8, the limiting screw rod 8 rotates to drive the limiting circular block 9 to move, the limiting circular block 9 moves to drive the limiting plate 10 to move, the limiting plate 10 moves at the same time to drive the T-shaped limiting block 11 to move in the T-shaped limiting slot 7, through the T-shaped limiting slot 7 and the T-shaped limiting block 11, the movement of the limiting plate 10 can be more stable, which is convenient for the use of the limiting plate 10. When the limiting plate 10 contacts the sheet metal, the worker continues to rotate the limiting screw rod 8 to make the limiting plate 10 preliminarily extrude and fix the sheet metal"; also please refer to the patent application for an adjustable sheet metal burr removing device, which was published on January 13, 2023 and has a publication number CN218284883U. In the specification

[0027] section, it is recorded that "the sheet metal part is clamped by the clamping device 2, the limiting screw rod 35 is rotated to make the sliding column 34 slide in the limiting slot 33, the sliding column 34 drives the lifting frame 41 to move, and the polishing sandpaper 44 is located at the side of the sheet metal part. Then the lifting screw rod 42 is rotated to make the grinding frame 43 lift in the lifting frame 41, and the polishing sandpaper 44 is attached to the corner of the sheet metal part, so that the burr removing device is suitable for various sheet metal parts".

[0030] [First Embodiment]

[0031] Reference Figures 1-5 The image shows a switch cabinet door corner grinding device disclosed in this embodiment. The switch cabinet door corner grinding device, as shown... Figures 1-2 As shown, the device includes an auxiliary plate 1, a grinding disc 2 rotatably connected to the bottom of the auxiliary plate 1, a motor 4 mounted on the top of the auxiliary plate 1, the output end of the motor 4 fixedly connected to the grinding disc 2, a body 5 mounted on the outer surface of the motor 4, an electric wire 6 mounted on one end of the body 5, and a handle 7 fixedly connected to one side of the body 5. The motor 4 is started by connecting to a power source via the electric wire 6. The output shaft of the motor 4 drives the grinding disc 2 to rotate. The user can perform corresponding grinding actions on the edges and corners of the switch cabinet to be ground by holding the handle 7.

[0032] The improvement of this embodiment compared with the prior art is that: a protective device 3 is provided on the outer surface of the auxiliary plate 1, and an anti-slip device 8 is provided on the outer surface of the grip 7. By providing the protective device, the grinding disc can be axially limited, effectively preventing the grinding disc from moving axially unexpectedly, thereby ensuring that the edges and corners to be ground in contact with the grinding disc are ground sufficiently and evenly, reducing the possibility of unexpected damage caused by the grinding process; by providing the anti-slip device 8, the friction of the outer surface of the grip 7 can be increased, so that the user can effectively prevent slipping when holding the grip 7.

[0033] like Figure 3As shown, the protection device 3 in this embodiment includes an extension block 31 fixedly connected to the top of the auxiliary plate 1, a threaded rod 32 screwedly connected to the inside of the extension block 31, and a clamping block 33 screwedly connected to the bottom end of the threaded rod 32. By arranging the clamping block, the threaded rod can drive the clamping block to move axially under the action of the threaded rod until the bottom of the clamping block is in complete abutment with the top of the polishing disc, so as to axially position the polishing disc and effectively prevent the polishing disc from moving axially unexpectedly. As a preferred, the top end of the threaded rod 32 is fixedly connected to an operation block 34, and the outer surface of the operation block 34 is provided with a protrusion. By arranging the operation block, rotating the operation block can drive the threaded rod to rotate, and the protrusion arranged on the outer surface of the operation block can effectively increase the friction of the outer surface of the operation block, which has an anti-skid effect when the operation block is rotated. Meanwhile, the top of the clamping block 33 is fixedly connected to a round rod 35, which is arranged in the inside of the extension block 31 and is in sliding connection therewith. By arranging the round rod, when the clamping block moves under the action of the threaded rod, the round rod will synchronously slide on the inner wall of the extension block, so as to limit the running direction of the clamping block. In addition, the bottom of the clamping block 33 is fixedly connected to a rubber plate 36, and the bottom of the rubber plate 36 is uniformly provided with a plurality of grooves. By arranging the rubber plate with grooves, the friction on one side of the clamping block can be increased, so that the clamping block can position the polishing disc more stably.

[0034] As shown, Figures 2-3 As shown, the auxiliary plate 1 is provided with a half ring 37 arranged on the outer periphery of the polishing disc 2, and the half ring 37 is fixedly connected to a mounting block 38 arranged on the middle of one side of the half ring 37. The outer edge of the extension block 31 is fixedly connected to a clamping block 39 which is located in the inside of the mounting block 38 and is in plug-in cooperation with the mounting block 38. As a further preferred of this embodiment, the clamping block 39 is made of magnet material, and the mounting block 38 is made of iron alloy material, and the two are magnetically attracted to each other. By arranging the half ring, the half ring is sleeved on the outer surface of the polishing disc, and the clamping block is inserted into the inner wall of the mounting block, and the clamping block made of magnet material can fix the mounting block made of iron alloy material, so as to fix the half ring, and the half ring can protect the polishing disc, which is conducive to preventing the side edge of the polishing disc from contacting other objects, and further improves the protection performance of the polishing disc.

[0035] As shown, Figures 4-5As shown, the anti-skid device 8 in the embodiment includes a rubber sleeve 81 sleeved on the outer periphery of the handle 7. By arranging the rubber sleeve, the friction of the outer surface of the handle can be increased, so that the anti-skid effect is achieved when the handle is held. As a pre-selection, the inner wall of the rubber sleeve 81 is fixedly connected with a clamping strip 82, the outer surface of the handle 7 is provided with a clamping groove 83, the outer surface of the clamping strip 82 is inserted into the inner part of the clamping groove 83 and is in plug-in cooperation with the clamping groove 83. By arranging the clamping strip and the clamping groove, the clamping strip is inserted into the inner part of the clamping groove, so that the rubber sleeve can be limited, which is beneficial to prevent the rubber sleeve from rotating when the handle is held.

[0036] The specific working process of the embodiment is as follows:

[0037] When it is necessary to limit the polishing disc 2, the operating block 34 is rotated to drive the threaded rod 32 to rotate. The threaded rod 32 can be telescoped in the inner part of the extension block 31. Under the limitation of the round rod 35, the threaded rod 32 can drive the clamping block 33 to move axially until the rubber plate 36 at the bottom of the clamping block 33 is in complete abutment with the top of the polishing disc 2, so that the polishing disc 2 can be axially limited, which effectively prevents the polishing disc from moving axially unexpectedly, thereby ensuring that the edge and corner to be polished in contact with the polishing disc are polished sufficiently and uniformly, and reducing the possibility of unintended damage caused by the polishing process.

[0038] When it is necessary to install the rubber sleeve 81, the rubber sleeve 81 is sleeved on the outer surface of the handle 7, the clamping strip 82 is inserted into the inner part of the clamping groove 83, one end of the rubber sleeve 81 is in abutment with one side of the fixed block 84, the threaded pin 85 is inserted into the inner part of the handle 7, the threaded pin 85 is driven into the inner wall of the handle 7 by rotating the dismounting block 86, and one side of the dismounting block 86 is in abutment with one end of the rubber sleeve 81, so that the rubber sleeve 81 can be fixed. The rubber sleeve 81 can increase the friction of the outer surface of the handle 7, so that the anti-skid effect is achieved when the handle 7 is held.

[0039] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
