Description

Technical Field

[0001] The present invention belongs to the technical field of cutting devices, and particularly relates to a cutting system for processing a refrigerator installation base. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and is also a civilian product that keeps food or other items in a constant low temperature state. Inside the box, there is a compressor, an ice maker, a cabinet or box for refrigeration, and a storage box with a refrigeration device. The volume of a household refrigerator is usually 20 to 500 liters.

[0003] Generally, the compressor and other parts inside the refrigerator are installed on a fixed base. In order to be suitable for the use of different models of refrigerators, the existing base needs to be cut. However, during the cutting process of the refrigerator base, it is necessary to cut the four sides of the refrigerator base four times in sequence. At the same time, during the cutting process, the burrs on the cutting surface need to be transferred to the next processing step for deburring, which not only increases the operation steps but also affects the production efficiency. For this reason, we provide a cutting system for processing a refrigerator installation base to solve the above problems. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Example 1, please refer to Figures 1-11, the present invention provides the following technical solutions: A cutting system for processing a refrigerator mounting base, including a clamping assembly 1; the clamping assembly 1 includes a bottom plate 101, and a clamping portion 2 for clamping the refrigerator mounting base is fixedly coupled to the top of the bottom plate 101; a cutting assembly 3 is slidably coupled to the top of the bottom plate 101. The cutting assembly 3 includes two sliding seats 301 slidably connected to match the clamping portion 2. The top of the sliding seat 301 is slidably connected to a top plate 302. A rectangular housing 303 is fixedly connected to the top of the top plate 302. A first motor 304 is fixedly connected inside the rectangular housing 303. The output shaft of the first motor 304 is fixedly connected to a first rotating shaft 305. A cutting disc 306 is fixedly connected to the end of the first rotating shaft 305; a first moving plate 307 is fixedly connected to the outer top of the rectangular housing 303. A bidirectional lead screw 308 is threadedly connected between the two first moving plates 307. A second moving plate 309 is rotatably connected to the circumferential surface of the bidirectional lead screw 308. A guiding conical tube 318 sleeved on the first rotating shaft 305 is fixedly connected to a side of the cutting disc 306 away from the second moving plate 309 (the guiding conical tube 318 is used to guide the edge metal waste generated by cutting away from the refrigerator mounting base 206 to avoid interfering with subsequent grinding operations. The setting of the guiding conical tube 318 causes the edge metal waste on the cut refrigerator mounting base 206 to be squeezed by the guiding conical tube 318, driving the edge metal waste to expand and bend away from the refrigerator mounting base 206, thereby ensuring that the grinding roller 403 smoothly fits the cutting surface, and further ensuring the normal grinding of the grinding roller 403).

[0032] A grinding assembly 4 is slidably coupled to the top of the sliding seat 301. The grinding assembly 4 includes a first slider 401 slidably connected to the top of the sliding seat 301. A second rotating shaft 402 is rotatably connected to the top of the first slider 401. A grinding roller 403 is fixedly connected to the circumferential surface of the second rotating shaft 402. An L-shaped plate 404 is rotatably connected to the circumferential surface of the second rotating shaft 402. The L-shaped plate 404 is fixedly coupled to the top plate 302. The top of the second rotating shaft is fixedly connected to a worm gear 405.

[0033] The operation process of this embodiment is as follows: Fix the refrigerator mounting base 206 through the clamping portion 2. According to the actual size requirements of the refrigerator mounting base 206, first control the rotation of the bidirectional lead screw 308, so that the bidirectional lead screw 308 drives the two first moving rods 307 to move towards or away from each other, and then drives the two cutting discs 306 to move towards or away from each other, thereby realizing the distance adjustment between the two cutting discs 306. Then start the two first motors 304. The output shaft of the first motor 304 drives the first rotating shaft 305 to rotate, and then drives the cutting disc 306 to rotate. Subsequently, control the second moving plate 309 to move from right to left (such as Figure 1 , 7As shown in FIGS. 8 and 9, the two rotating cutting discs 306 are driven to cut the two side surfaces of the refrigerator mounting base 206. At the same time, during the process of the two cutting discs 306 moving from right to left, the worm 506 is synchronously controlled to rotate to drive the worm gear 405, so that the worm gear 405 drives the second rotating shaft 402 to rotate, the second rotating shaft 402 drives the grinding roller 403 to rotate, and the grinding roller 403 grinds the two cut surfaces of the refrigerator mounting base 206, thereby completing the grinding of the burrs on the two cut sections, so as to improve the smoothness of the cut surface. After the two side surfaces of the refrigerator mounting base 206 are cut, the two cutting discs 306 are controlled to reset. At this time, during the reset process, the grinding roller 403 grinds the cut section again to further improve the smoothness of the cut section;

[0034] Then, by controlling the clamping part 2 to drive the refrigerator mounting base 206 to rotate 90°, the other two uncut side surfaces of the refrigerator mounting base 206 face the two cutting discs 306, and the above operation is repeated again to complete the cutting and grinding of the other two side surfaces of the refrigerator mounting base 206. By using the two cutting discs 306 at the same time and the distance between the two cutting discs 306 being adjustable, the device can meet the cutting requirements of the refrigerator mounting base 206 with different sizes, changing the original four cuts of the refrigerator mounting base 206 into two cutting operations, effectively improving the cutting efficiency. At the same time, during the cutting process, the grinding of the cut surface is synchronously completed, ensuring the smoothness of the cut section after cutting, and improving the cutting quality and production efficiency.

[0037] The operation process of this embodiment is as follows: By controlling the second motor 103 to drive the threaded rod 104 to rotate, the threaded rod 104 drives the second moving plate 309 to move, providing power for the movement of the second moving plate 309.

[0038] First, align the square hole 207 on the refrigerator mounting base 206 with the square rod 204 and sleeved and installed on the support plate 203.

An electromagnetic valve is installed on the discharge pipe 315. A first limiting groove 316 slidably matched with the top plate 302 is formed in the top of the sliding seat 301. A second limiting groove 317 slidably matched with the first slider 401 is formed in the top of the sliding seat 301.

[0040] The operation process of this embodiment is as follows: By starting the driving motor 310, the driving motor 310 drives the first straight gear 311 to rotate, and then drives the second straight gear 312 meshing with it to rotate, thereby driving the bidirectional lead screw 308 to rotate, providing power for the rotation of the bidirectional lead screw 308.

[0041] By arranging a collection box 314 directly below the cutting disc 306, the collection box 314 collects the debris generated during the cutting process. After the collection box 314 is full of debris, by controlling the solenoid valve to open, the debris in the collection box 314 is concentrated and discharged, avoiding the splashing of waste chips during the cutting process and affecting the cleanliness of the operation platform.
