[0001] The utility model belongs to the technical field of refrigerator sheet metal grinding, in particular to a refrigerator sheet metal grinding device. Background Art

[0002] Sheet metal parts are needed to make up the refrigerator. After welding, drilling, stamping and other processes are completed, burrs and flash will form on the surface of the sheet metal parts. Grinding is an indispensable part of the sheet metal processing technology. Sheet metal parts need to be polished before they can be used.

[0003] Existing refrigerator sheet metal grinding devices are difficult to adapt to different sheet metal parts. For example, the sheet metal grinding device shown in Patent Publication No. CN221495418U includes a processing table with a protective plate fixedly mounted on its upper surface. Because refrigerator sheet metal parts are numerous and of varying sizes and shapes, some sheet metal parts are better clamped from the outside, while others require clamping from the inside. This patent fails to meet these requirements.

[0004] To this end, we propose a refrigerator sheet metal grinding device to solve the above problems. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-3 A refrigerator sheet metal grinding device includes a processing table 1, a placement rack 2 is fixedly installed in the middle of the top surface of the processing table 1, and a plurality of through slots 3 are formed in a circumferential array on the top surface of the placement rack 2. A slider 4 is slidingly provided in the through slot 3, and a driving assembly 5 for driving the slider 4 is provided in the through slot 3. The driving assembly 5 is a prior art, including an electric push rod fixedly installed in the through slot 3, and the other end of the electric push rod is fixedly connected to the side of the slider 4. Figure 4-5 Both sides of the top surface of the slider 4 are hinged with a stopper 7 through a hinge 6, and the hinge 6 is located on the side where the two stoppers 7 are close to each other. The side of one of the stoppers 7 fits the slider 4 and the top surface is not higher than the top surface of the placement rack 2, and the bottom surface of the other stopper 7 fits the slider 4.

[0028] Reference Figure 1 、 Figure 6 , and also includes a grinder 8 arranged above the processing table 1. A plurality of ventilation holes 9 are opened on the top surface of the processing table 1. A suction component 10 is provided inside the processing table 1. The grinder 8 and the suction component 10 are both existing technologies and are relatively common in the field of grinding, so they will not be described in detail.

[0029] Before securing the sheet metal component, all stops 7 are rotated perpendicular to the sliders 4. The sheet metal component is then placed in the center of the rack 2, with its sidewall positioned between two stops 7 on the same side. Depending on the situation, either external or internal securing is selected. If securing the sheet metal component from the inside is more effective, the drive assembly 5 drives the multiple sliders 4 away from each other until the stop 7 on the inside of the sheet metal component abuts against the inside wall, achieving primary securing of the sheet metal component. The other stop 7 is then rotated and abutted against the outside wall, achieving secondary securing of the sheet metal component.

[0030] It should be noted that when fixing from the outside, since the stopper 7 inside the sheet metal is difficult to operate and rotate, it is possible to consider only using the main fixing position stopper 7. If auxiliary fixing is required, the sheet metal can be placed by first stopping it in mid-air, then rotating the inner stopper 7 until it is in contact with the inner wall of the sheet metal, and then completely placing the sheet metal on the placement rack 2.

[0031] After the fixation is completed, the sheet metal part can be polished by the polishing machine 8. During polishing, negative pressure is formed by the suction component 10, and the polished waste particles pass through the through groove 3 and the ventilation hole 9 and fall into the inside of the processing table 1.

[0032] Reference Figure 2-5 Since the waste particles from grinding will fall through the through groove 3 into the ventilation hole 9, if a slide rail is provided inside the through groove 3 to provide sliding support for the slider 4, the waste particles may have a significant impact on the slide rail. The lower part of the through groove 3 is funnel-shaped, and the two sides of the lower part of the slider 4 are inclined surfaces that fit the through groove 3. This can provide support for the slider 4 without the need for a slide rail.

[0033] In order to minimize the impact of the grinding waste particles on the drive component 5, the drive component 5 is located on the side where multiple through slots 3 are close to each other. Since the sheet metal will be covered above the drive component 5 during grinding, most of the waste particles will not pass through the drive component 5.

[0034] Both the slider 4 and the stopper 7 are provided with a mounting groove 11 for mounting the hinge 6 , one side of the hinge 6 is flush with the top surface of the slider 4 , and the other side of the hinge 6 is flush with the side surface of the stopper 7 .

[0035] In order to increase the friction between the two blocks and the sheet metal parts and provide a buffer when the sheet metal parts are fixed, the upper part of the side where the two blocks 7 are close to each other is concave, and a pad 12 is fixedly connected to the concave part. The side of the pad 12 is flush with the side of the block 7. The pad 12 should be made of soft materials such as rubber.

[0036] The upper end of the pad 12 is chamfered. The chamfering can prevent the pad 12 from pressing the hinge of the hinge 6, and can also increase the contact area with the sheet metal when the pad 12 is in an inclined state, thereby improving the fixing stability.

[0037] In order to facilitate the operation of the rotation of the stopper 7 , a groove 13 is provided on the side of the stopper 7 facing away from the cushion block 12 .

[0038] Due to the presence of the groove 13, the waste particles polished off may enter the groove 13. The groove 13 is cut at one end near the hinge 6, so that when the stopper 7 is vertical, the waste particles can fall into the through groove 3 along the cut corner.

[0039] Reference Figure 6 A filter plate 14 is detachably mounted inside the processing table 1, and the filter plate 14 is located between the ventilation hole 9 and the suction assembly 10. The waste particles polished are collected by the filter plate 14 to reduce pollution and avoid damage to the suction assembly 10.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
