[0002] In the field of cutting and processing refrigeration compressor castings, existing cutting equipment generally suffers from fixed size and inconvenient storage and transportation. The support structure of traditional cutting equipment is mostly fixed, which cannot be folded and stored according to the space conditions of the construction site. As a result, the equipment occupies a lot of space during transportation and is difficult to arrange flexibly in narrow construction environments. Especially when cutting is required on special working surfaces such as rooftops, the fixed size of the equipment makes operation even more inconvenient and seriously affects construction efficiency.

[0009] This utility model provides a cutting device for refrigeration compressor castings. It has the following advantages:

[0010] (I) The cutting equipment for casting refrigeration compressors has a main plate and a secondary plate connected by a hinge to form a foldable structure. When the equipment needs to be stored, the secondary plate can rotate around the hinge. The sliding connection structure between the insert and the threaded cylinder plays a guiding and limiting role, ensuring that the folding process is smooth and orderly. The rotating threaded column pushes the limiting frame to slide along the outer wall of the threaded cylinder, which drives the insert to move, so that the insert matches the insertion hole position of the main plate and the secondary plate after folding, thus realizing the secure storage of the folded components. This design can reduce the overall size of the equipment, making it convenient for transportation and storage. It is especially suitable for the space-constrained environment of the construction site, while reducing the floor space occupied when the equipment is idle.

[0011] (II) The cutting equipment for refrigeration compressor castings enhances the fixation effect between the equipment and the worktable through the suction cups at the bottom of the support feet, reducing displacement during the cutting process. The buffer structure formed by the air bladder inside the fixed feet and the anti-slip feet can absorb the vibration energy of the equipment. The buffer bladder further attenuates the vibration, ensuring that the saw blade remains stable during cutting. This improves the quality of the cut surface, reduces cutting errors caused by vibration, and increases the pass rate of casting cutting. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a cutting device for refrigeration compressor castings, including: a stepper motor 4 and a saw blade 1, and also including: a folding assembly 2, the bottom of which is fixedly connected to the outer wall of the stepper motor 4 via a frame, and buffer assemblies 3 are fixedly connected to the corners of the folding assembly 2; the folding assembly 2 includes a main plate 21, the outer wall of which is rotatably connected to a secondary plate 24 via a hinge, and the inner walls of both the main plate 21 and the secondary plate 24 are slidably connected to threaded cylinders 23 via inserts 22, with the outer wall of the inserts 22 inserted into the inner wall of the main plate 21, and the outer wall of the threaded cylinders 23 being connected to the inner wall of the main plate 21. A limiting frame 26 is slidably connected to the limiting ring 28, and the inner wall of the limiting ring 28 is slidably connected to the outer wall of the threaded cylinder 23. Threaded columns 25 are threadedly connected to the inner walls on both sides of the threaded cylinder 23. By rotating the threaded columns 25, they can be moved axially within the threaded cylinder 23, thereby pushing the limiting frame 26 to slide along the outer wall of the threaded cylinder 23. The limiting frame 26 is connected to the threaded cylinder 23 through the limiting ring 28. The slider 27 on the inner wall of the limiting ring 28 cooperates with the groove on the outer wall of the threaded cylinder 23 to ensure that the limiting frame 26 can only move axially. The limiting frame 26 drives the insertion column 22 to move, thereby changing the position of the two sets of insertion columns 22.

[0021] The inner wall of the insert 22 is slidably connected to the outer wall of the threaded cylinder 23. The outer wall of the limiting ring 28 is fixedly connected to the outer wall of the limiting frame 26. The inner wall of the limiting ring 28 is fixedly connected to the slider 27. The bottom of the sub-plate 24 is fixedly connected to the outer wall of the stepper motor 4 through a bracket. The output end of the stepper motor 4 is fixedly installed to the inner wall of the saw blade 1. The outer wall of the slider 27 is slidably connected to the inner wall of the threaded cylinder 23. The outer wall of the limiting frame 26 is engaged with the end of the insert 22 away from the main body 21. The side of the limiting frame 26 away from the insert 22 is rotatably connected to the outer wall of the threaded column 25.

[0022] The buffer assembly 3 includes a support foot 31, a fixed foot 35 fixedly connected to the bottom of the support foot 31, a suction cup 32 fixedly connected to the outer wall of the fixed foot 35, and an anti-slip foot 33 fixedly connected to the inner wall of the fixed foot 35 via an airbag 36. The top of the airbag 36 is fixedly connected to the inner wall of the fixed foot 35, and a buffer bladder 34 is fixedly connected to the outer wall of the top of the anti-slip foot 33. The top of the support foot 31 is fixedly connected to the bottom of the main body 21, and the outer wall of the buffer bladder 34 is fixedly connected to the outer wall of the anti-slip foot 33. The suction cup 32 at the bottom of the fixed foot 35 enhances the fixation effect of the device and reduces displacement through adsorption. The airbag 36 on the inner wall of the fixed foot 35 and the anti-slip foot 33 form a buffer structure. When the device is vibrated, the anti-slip foot 33 can move inside the fixed foot 35, squeezing the airbag 36 and absorbing the vibration energy by utilizing the compressibility of the gas. The bottom of the airbag 36 is fixedly connected to the inner wall of the anti-slip foot 33.

[0023] In the cutting operation of refrigeration compressor castings, the equipment achieves an efficient and stable cutting process through the coordinated operation of various components. Its core working principle revolves around the structural design of the folding component 2 and the buffer component 3, and is combined with the power system and transmission mechanism to form a complete cutting work system.

[0024] When the equipment is started, the stepper motor 4 starts to run as a power source, and its output end drives the saw blade 1 to rotate at high speed, providing basic power for the cutting operation. At the same time, the folding component 2 plays a key supporting and storage role. The main body 21 and the secondary body 24 are connected by a hinge to form a foldable structure. When the folding component 2 needs to be unfolded, the secondary body 24 can rotate around the hinge. During this process, the sliding connection structure of the insert 22 and the threaded cylinder 23 plays a guiding and limiting role, ensuring the position of the main body 21 and the secondary body 24.

[0025] When it is necessary to fix the folding component 2, the threaded column 25 is rotated to move axially within the threaded cylinder 23, thereby pushing the limiting frame 26 to slide along the outer wall of the threaded cylinder 23. The limiting frame 26 is connected to the threaded cylinder 23 through the limiting ring 28. The slider 27 on the inner wall of the limiting ring 28 cooperates with the groove on the outer wall of the threaded cylinder 23 to ensure that the limiting frame 26 can only move axially. The limiting frame 26 drives the insertion column 22 to move, thereby changing the position of the two sets of insertion columns 22 and matching the corresponding insertion holes of the main board 21 and the sub-board 24. Since the corresponding insertion hole positions of the main board 21 and the sub-board 24 are different after folding and unfolding, the limiting frame 26 is moved by rotating the threaded column 25 to change the position between the two sets of insertion columns 22, thereby realizing the folding and storage of the folding component 2.

[0026] During the cutting process, the equipment may be affected by external forces such as vibration. At this time, the buffer component 3 plays a role in ensuring the stability of the cutting and the safety of the equipment. The support foot 31 connects the bottom of the main body 21 to the ground or work platform. The suction cup 32 at the bottom of the fixed foot 35 enhances the fixation effect of the equipment through adsorption and reduces displacement. The air bladder 36 on the inner wall of the fixed foot 35 and the anti-slip foot 33 form a buffer structure. When the equipment is vibrated, the anti-slip foot 33 can move inside the fixed foot 35 and squeeze the air bladder 36. The compressibility of the gas is used to absorb the vibration energy. At the same time, the buffer bladder 34 at the top of the anti-slip foot 33 further buffers the vibration, reduces the impact of vibration on the cutting accuracy, and ensures that the saw blade 1 remains stable when cutting the refrigeration compressor casting.
