[0001] This utility model relates to the technical field of refrigerator cover production equipment, and more particularly to a drilling device for processing refrigerated air duct cover plates. Background Technology

[0002] The cover plate is an important component of the refrigerator's cooling air duct. During the refrigerator assembly process, the cover plate needs to be fixed to the refrigerator by threaded installation to make it a whole. This requires drilling holes in the cover plate of the refrigerator's cooling air duct and then tapping the cover plate.

[0003] In existing drilling operations, the cover plate is usually placed directly on the workbench, and then the worker manually moves the cover plate to align the side of the cover plate with the positioning pin and straighten it. Finally, the cover plate is pressed down and holes are drilled in the cover plate using a drilling tool (such as a hand drill).

[0004] However, during the process of aligning the cover plate, the side of the cover plate and the surface of the workbench are prone to friction, which poses a risk of scratching the side of the cover plate and reducing product quality. Utility Model Content

[0005] In view of the above problems, this utility model provides a drilling device for processing refrigerated air duct cover plates, the purpose of which is to reduce the risk of the cover plates being scratched and to ensure product quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drilling device for processing refrigerated air duct cover plates is provided, comprising: a worktable for placing the cover plate; a plurality of positioning blocks disposed on the worktable for abutting the sides of the cover plate; a plurality of through holes extending vertically through the worktable; a support plate slidably disposed below the worktable; a plurality of universal balls for rotatably supporting the cover plate, each universal ball being installed on the support plate corresponding to a through hole; an elastic support component for elastically supporting the support component, fixing the universal balls protruding from the support plate at a fixed height; a pressing assembly disposed on the worktable above the cover plate for pressing against the cover plate; and a drilling assembly for drilling holes in the cover plate.

[0007] Furthermore, the device also includes: a guide post, one end of which is located below the worktable, and a support plate that is slidably fitted onto the guide post; a limiting block, located at the end of the guide post away from the worktable, and an elastic support component located between the limiting block and the support plate.

[0008] Furthermore, the device also includes several clearance grooves formed on the surface of the worktable to make way for the drilling assembly.

[0009] Furthermore, the pressing assembly includes: a bracket, fixedly mounted on the worktable; a pressing column, slidably passing through the bracket; a first telescopic component, the main body of which is fixedly mounted on the bracket, and the piston rod of which is connected to the pressing column; and a pressing ring, fixedly mounted on one end of the pressing column for pressing against the cover plate.

[0010] Furthermore, the press-fit assembly also includes: several support ribs, one end of which is connected to the press-fit ring, and the other end of which is connected to the press-fit column.

[0011] Furthermore, the drilling assembly includes: a second telescopic component, the main body of which is fixedly mounted; a mounting base disposed on the piston rod of the second telescopic component; a drilling motor disposed on the mounting base; and a drilling drill bit disposed on the output shaft of the drilling motor.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the cover plate is rolled and contacted by a universal ball, which makes it easy to slide the cover plate on the universal ball until the side of the cover plate abuts the positioning block and completes the positioning. This can effectively prevent the side of the cover plate from being scratched and ensure product quality. Attached Figure Description

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 and Figure 2As shown in the embodiment of this application, a drilling device for processing a refrigerated air duct cover plate is disclosed, comprising: a workbench 1 for placing a cover plate 6; a plurality of positioning blocks 11 disposed on the workbench 1 for abutting the sides of the cover plate 6; a plurality of through holes 12 extending vertically through the workbench 1; a support plate 2 slidably disposed below the workbench 1; a plurality of universal balls 21 for rotatably supporting the cover plate 6, each universal ball 21 being installed on the support plate 2 corresponding to each through hole 12; an elastic support component 3 for elastically supporting the support component, fixing the universal balls 21 protruding from the support plate 2 at a fixed height; a pressing assembly disposed on the workbench 1 above the cover plate 6 for pressing against the cover plate 6; and a drilling assembly for drilling holes in the cover plate 6.

[0018] In practical use, the cover plate 6 to be drilled is placed on the universal ball 21, and the operator moves the cover plate 6 to slide on the universal ball 21 until the side of the cover plate 6 abuts against the positioning block 11, thus completing the positioning of the cover plate 6; then the pressing assembly is activated to press down the cover plate 6, which can press down the universal ball 21 and the supporting plate 2 as a whole until the cover plate 6 is pressed tightly on the worktable 1, and finally the drilling assembly completes the drilling operation of the cover plate 6.

[0019] In this invention, the cover plate 6 is rolled and contacted by the universal ball 21, which makes it easy to slide the cover plate 6 on the universal ball 21 until the side of the cover plate 6 abuts against the positioning block 11 to complete the positioning. This can effectively prevent the side of the cover plate 6 from being scratched and ensure product quality.

[0020] The bearing plate 2 is also elastically supported by springs, and the press-fitting component can press down the universal ball 21 and the cover plate 6 as a whole. The cover plate 6 is stably pressed onto the worktable 1, which facilitates subsequent drilling operations.

[0021] In this embodiment, the positioning block 11 is detachably mounted on the workbench 1 by screws, and two positioning blocks 11 are respectively provided on the two vertical sides of the cover plate 6; of course, the number and position of the mounting blocks can be flexibly changed.

[0022] Preferably, the device further includes: a guide post 22, one end of which is disposed below the worktable 1, and the bearing plate 2 is slidably sleeved on the guide post 22; a limiting block 23, which is disposed at the end of the guide post 22 away from the worktable 1, and the elastic support component 3 is located between the limiting block 23 and the bearing plate 2.

[0023] Specifically, the elastic support component 3 is a spring, which is sleeved on the guide post 22. One end of the spring abuts against the bearing plate 2, and the other end of the spring abuts against the limiting block 23.

[0024] It is worth mentioning that any existing models of springs and universal balls can be used.

[0025] Specifically, the device also includes several clearance grooves 24 formed on the surface of the worktable 1 to make way for the drilling assembly.

[0026] Specifically, the pressing assembly includes: a bracket 41, fixedly mounted on the workbench 1; a pressing column 42, slidably passing through the bracket 41; a first telescopic component 43, the main body of which is fixedly mounted on the bracket 41, and the piston rod of which is connected to the pressing column 42; and a pressing ring 44, fixedly mounted on one end of the pressing column 42, for pressing against the cover plate 6.

[0027] During operation, the piston rod of the first telescopic component 43 extends, which drives the pressing column 42 to slide downward, thereby driving the pressing ring 44 to approach the cover plate 6 until the pressing ring 44 presses the cover plate 6 tightly.

[0028] Specifically, the press-fitting assembly also includes: a number of support ribs 45, one end of which is connected to the press-fitting ring 44, and the other end of which is connected to the press-fitting column 42.

[0029] In this embodiment, the pressing ring 44 is connected and installed on the pressing column 42 by the support rib 45. The support rib 45 and the pressing ring 44 are hollowed out, which can provide effective pressing while reducing the area of ​​the cover plate 6 that is covered, making it easier for the drilling assembly to perform drilling operations.

[0030] Specifically, the drilling assembly includes: a second telescopic component 51, the main body of which is fixedly installed; a mounting base 52, which is disposed on the piston rod of the second telescopic component 51; a drilling motor 53, which is disposed on the mounting base 52; and a drilling drill bit 54, which is disposed on the output shaft of the drilling motor 53.

[0031] When drilling is required, the drilling motor 53 starts, and the output shaft of the drilling motor 53 drives the drilling bit 54 to rotate. Through the piston rod of the second telescopic component 51, the piston rod extends, which drives the rotating drilling bit 54 to contact the cover plate 6 and complete the drilling operation.

[0032] It is worth mentioning that the punching brick on the punching motor 53 can enter the clearance groove to ensure complete penetration of the cover plate 6.

[0033] It is understandable that the installation positions of the clearance groove and the pressure ring 44 can be flexibly changed according to the hole positions on the cover plate 6.

[0034] It is worth mentioning that the first telescopic component 43 and the second telescopic component 51 can be any commercially available electric push rod. The main body of the first telescopic component 43 and the main body of the second telescopic component 51 can be installed on the bracket 41 by means of flanges and bolts, respectively. The mounting base 52 can also be installed on the piston rod of the second telescopic component 51 by means of flanges and bolts.
