Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, and in particular to a compressor housing cutting device with adjustable cutting depth. Background Technology

[0002] In the recycling process of refrigeration equipment (such as air conditioners and refrigerators), the compressor, as a core component, has high recycling value and environmental protection requirements. Disassembling the compressor casing is a crucial step in the recycling process. Its purpose is to separate the casing from internal precision components (such as motors, pump bodies, and valve plates) so that the metal casing can be melted down and recycled, while simultaneously recovering high-value internal parts or performing harmless treatment. However, currently, the industry commonly uses manual operation of cutting machines for casing disassembly.

[0003] Because compressor casings are often irregularly shaped (such as cylindrical, elliptical, or irregularly shaped structures), it is difficult to stably control the cutting path and depth during manual operation. Specifically, operators need to rely on experience to judge the cutting progress, but the distance between the compressor casing and internal components (such as motor stator, crankshaft, etc.) is usually only 5-10mm. Cutting too deep may damage the internal precision structure, leading to the scrapping of core components. In addition, manual operation is labor-intensive.

[0004] Therefore, this application provides a compressor housing cutting device with adjustable cutting depth to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide a compressor housing cutting device with adjustable cutting depth, which solves the technical problem that existing manual cutting cannot accurately control the cutting path and depth.

The rightmost end of the depth-limiting roller is located to the left of the rightmost end of the cutting blade, and the transverse axis of the depth-limiting roller and the transverse axis of the cutting blade are located in the same vertical plane.

[0011] A column is slidably provided on the mounting base, and a weight is fixed at the upper end of the column. The weight is movably connected to the mounting plate through a movable rod. The lower end of the column passes through a rectangular opening at the upper end of the U-shaped fixing base and is connected to a contact roller.

[0026] 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.

[0027] Example: Reference Figure 1The compressor housing cutting device with adjustable cutting depth shown includes a frame 1, a clamping and rotating mechanism 2 installed on the frame 1, and an automatic cutting mechanism 3 for automatically cutting the irregular compressor housing 5 to a constant depth. The automatic cutting mechanism 3 is configured in two sets, which are arranged opposite to each other on both sides of the clamping and rotating mechanism 2.

[0028] The cutting depth adjustment mechanism 4 is used to adjust the cutting depth of the compressor housing 5.

[0029] When in use, the compressor housing 5 can be placed directly on the clamping and rotating mechanism 2. The clamping and rotating mechanism 2 clamps and rotates the compressor housing 5, and controls the automatic cutting mechanism 3 to work. The compressor housing 5 with irregular shape is cut to a constant depth during rotation, which effectively avoids damage to the internal components of the compressor housing 5 and reduces labor intensity.

[0030] Meanwhile, a cutting depth adjustment mechanism 4 is provided, which can adjust the cutting depth of the compressor housing according to actual cutting needs to achieve different cutting depths.

[0031] As a preferred embodiment of this example, Figure 2 and Figure 3 As shown, the automatic cutting mechanism 3 includes a cutting cylinder 302 mounted on a U-shaped fixed base 301, a track plate 303 linearly slidably mounted on the U-shaped fixed base 301, and a mounting plate 305 slidably mounted on a mounting base 304 via a slider 306.

[0032] The track plate 303 is fixedly connected to the output end of the cutting cylinder 302, and the mounting base 304 is fixedly mounted on the track plate 303.

[0033] A motor-driven cutting blade 307 is mounted on the mounting plate 305, and a depth limiting roller 308 is rotatably arranged directly below the cutting blade 307. The rightmost end of the depth limiting roller 308 is located to the left of the rightmost end of the cutting blade 307, and the horizontal axis of the depth limiting roller 308 and the horizontal axis of the cutting blade 307 are located in the same vertical plane.

[0034] A column 311 is slidably provided on the mounting base 304, and a weight 310 is fixed at the upper end of the column 311. The weight 310 is movably connected to the mounting plate 305 through the movable rod 309. The lower end of the column 311 passes through the rectangular opening provided at the upper end of the U-shaped fixing base 301 and is connected to the contact roller 314. The contact roller 314 rolls against the upper end of the support plate 312 provided in the inner cavity of the U-shaped fixing base 301. A lifting cylinder 313 is provided on the right side of the support plate 312.

[0035] In use, the compressor housing 5 can be manually placed directly on the clamping and rotating mechanism 2. The clamping and rotating mechanism 2 clamps the compressor housing 5. At the same time, the output ends of the two sets of cutting cylinders 302 drive the track plate 303 to move relative to each other. When the track plate 303 moves, it drives the lower end of the column 311 to move laterally on the support plate 312. With the help of the movable rod 309, the mounting plate 305 and the column 311 can be pushed to move laterally together. After the contact roller 314 is completely disengaged from the support plate 312 (at this time, the cutting cylinder 301 stops working), the column 311 will move downward due to the gravity of the weight 310. The downward movement of the column 311 will cause the movable rod 309 to push the mounting plate 305 forward. After moving a certain distance, the rotating cutting blade 307 will contact the outer wall of the compressor housing and cut. As the cutting progresses, the cutting depth of the cutting blade increases due to the gravity of the weight 310. The cutting depth is gradually increased until the depth-limiting roller 308 contacts the outer wall of the compressor housing 5, at which point the cutting blade cannot move and the cutting depth remains constant. At this point, the clamping and rotating mechanism 2 is controlled to rotate the compressor housing 5. During the rotation, the weight of the weight 310 will cause the outer wall of the depth-limiting roller 308 to adhere tightly. As the depth-limiting roller 308 travels along the undulating outer wall of the compressor housing 5, the corresponding cutting roller 307 will move back and forth to ensure a constant cutting depth and avoid damage to the internal components of the compressor housing 5. After the cutting is completed, the lifting cylinder 313 is activated to lift the contact roller 314 to the same horizontal height as the support plate 312. At this point, the cutting cylinder 301 is activated to drive the mounting base 304 and mounting plate 305 back to their original positions, and then the lifting cylinder 313 returns to its original position. The operator removes the cut compressor housing 5 and replaces it with an uncut compressor housing 5, and repeats the above operation.

[0036] It should be noted that: First, the cutting cylinder 301, the lifting cylinder 313, the motor, and the clamping and rotating mechanism are all electrically connected to the PLC controller; Second, the rightmost end of the depth-limiting roller 308 is located to the left of the rightmost end of the cutting blade 307, and the straight-line distance between the two rightmost ends is the cutting depth of the cutting roller 307. The transverse axis of the depth-limiting roller 308 and the transverse axis of the cutting blade 307 are located in the same vertical plane. This design is intended to help to adapt and adjust the movement state of the cutting roller 307 in a timely manner according to the undulation of the compressor housing 5, so as to avoid damage to the internal components of the compressor housing 5; Third, the cutting blade 307 will only contact the compressor housing 5 and make a cut after the contact roller 314 has completely separated from the support plate 312, so that the weight of the object 310 is completely converted into the driving force for the mounting plate 305 to move; Fourth, the motor-driven cutting blade 307 can be replaced by a pneumatic roller cutter (existing technology).

[0037] As a preferred embodiment of this example, Figure 4As shown, the cutting depth adjustment mechanism 4 includes a mounting strip 41 with an movable opening and a sliding plate 42 slidably disposed on the mounting strip 41;

[0038] A rotating rod is rotatably mounted on the upper end of the slide plate 42, and the lower end of the rotating rod passes through the movable opening and is rotatably connected to the depth limiting roller 308. A threaded tube 43 is fixed on the side end of the slide plate 42.

[0039] The upper end of the mounting strip 41 is rotatably provided with a screw 44, and an elastic damping ring is provided at the rotatable connection between the screw 44 and the mounting strip 41. The threaded end of the screw 44 is threadedly connected to the threaded tube 43.

[0040] Before the cutting cylinder 301 starts working, the screw 44 can be rotated, which in turn drives the slide plate 42 to move laterally through the threaded tube 43, thereby causing the depth limiting roller 308 to move laterally, ultimately adjusting the cutting depth. The elastic damping ring provides resistance to the rotation of the screw 44, preventing it from rotating and contributing to the stability of the cutting depth.

[0041] It should be noted that the mounting strip 41 is fixedly mounted on the mounting plate 305.

[0042] As a preferred embodiment of this invention, a ball bearing is provided at the connection between the mounting base 304 and the column 311.

[0043] The ball bearings reduce friction between the column 311 and the mounting base 304.

[0044] As a preferred embodiment of this example, Figure 5 As shown, the clamping and rotating mechanism 2 includes a turntable 202 rotatably mounted on the frame 1. A centering clamp 201 is installed on the upper end of the turntable 202. A toothed ring 203 is fixedly sleeved on the outer wall of the turntable 202, and the toothed ring 203 is meshed with the drive gear 204. The drive gear 204 is installed at the output end of the drive motor 205, and the drive motor 205 is installed on the frame 1.

[0045] In use, the compressor housing 5 is placed on the centering clamp 201 and clamped and fixed by the clamping plate on it. After that, when the cutting blades 307 on both sides form a constant cutting depth on the compressor housing 5, the drive motor 205 is controlled to drive the turntable 202 to rotate, so that the compressor housing 5 clamped on it can rotate one revolution to complete the cutting of the compressor housing 5.

[0046] It should be noted that the centering clamp 201 includes two clamping plates pushed by a cylinder, and the clamping surface of the clamping plates is consistent with the outer surface of the compressor housing 5. The compressor housing 5 is clamped and fixed by the relative movement of the two clamping plates pushed by the cylinder.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
