Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser cutting device for the port of an air conditioner compressor housing. Background Technology

[0002] Air conditioner compressor housings are usually made of aluminum die castings. Therefore, after die casting, there is usually a material shank on the open end face of the air conditioner compressor housing. The material shank needs to be cut off. Thus, in the production process of air conditioner compressors, the cutting and processing of the compressor housing is a key step, which requires the use of cutting equipment. Traditional air conditioner compressor housing cutting devices typically use a fixed clamping mechanism to hold the housing in place for the cutting operation; however, existing cutting and fixing methods have significant limitations: On the one hand, the shell needs to be manually fixed before cutting, which increases the complexity of the operation and makes it less convenient; On the other hand, during the cutting process, a separate drive mechanism is required to rotate the housing to perform the cutting work, which increases the operating cost of the equipment. On the other hand, the mechanisms for clamping, rotating, and cutting the shell work independently, and the adjustment and operation are cumbersome. They cannot achieve linkage and synchronous operation, which can easily lead to limitations in the cutting accuracy and efficiency of the shell. Based on this, the present invention provides a laser cutting device for the port of an air conditioner compressor housing to solve the problems mentioned in the background art. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0016] refer to Figures 1 to 6 A laser cutting device for the housing port of an air conditioner compressor includes a laser cutting head 1, a counterweight base 101, a support plate 102, a mounting plate 103, a U-shaped plate 104, a support disk 105, a first electric push rod 106, a second electric push rod 107, and a connecting plate 2. Four support plates 102 are installed on one end of the counterweight chassis 101, and the same support plate 105 is installed on the other end of the four support plates 102. A connecting plate 2 is movably installed above the support plate 105, and the two ends of the connecting plate 2 are respectively connected to two vertical plates of U-shaped plate 104. An intermittent mechanism is installed between the counterweight chassis 101 and the support plate 105 to drive the connecting plate 2 to rotate intermittently and achieve shell cutting; A mounting plate 103 is vertically connected to the lower outer side of the support plate 102 on the left side. A fixed end of a first electric push rod 106 is installed on the other end of the mounting plate 103. The first electric push rod 106 is located on the outer side of the U-shaped plate 104 on the left side. The telescopic end of the first electric push rod 106 is vertically connected to the fixed end of a second electric push rod 107. The telescopic end of the second electric push rod 107 is connected to a laser cutting head 1. A limiting mechanism for clamping and limiting the housing is installed on the U-shaped plate 104. The limiting mechanism is driven by an intermittent mechanism. The U-shaped plate 104 has a rotating mechanism installed inside the horizontal plate to rotate and cut the shell. The rotating mechanism is driven by an intermittent mechanism. It should be noted that the first electric push rod 106 is used to adjust the height of the laser cutting head 1 by moving it up and down, and the second electric push rod 107 is used to adjust the position of the laser cutting head 1 by moving it left and right, so as to facilitate the cutting of different compressor housings. It is worth mentioning that the first electric actuator 106, the second electric actuator 107 and the third electric actuator 37 described later are all commercially available electric actuators, which can only move linearly back and forth along the axial direction and cannot rotate circumferentially around their axis. This is existing technology. It is worth mentioning that the laser cutting head 1 is electrically connected to the external control components. When the U-shaped plate 104 drives the compressor housing to rotate to the right side of the laser cutting head 1, the laser cutting head 1 opens. When the U-shaped plate 104 drives the compressor housing to move from the right side of the laser cutting head 1, the laser cutting head 1 closes, thus realizing the laser cutting of the compressor housing. The intermittent mechanism includes a drive component 21, a first rotating shaft 22, a first turntable 23, a shift post 24, a diamond-shaped plate 25, a first arc-shaped rack 26, a second turntable 27, and a second rotating shaft 28; A first rotating shaft 22 is rotatably passed through the support plate 105 between the four support plates 102. One end of the second rotating shaft 28 is rotatably connected to the counterweight base 101, and the other end of the second rotating shaft 28 is connected to the bottom of the connecting plate 2. A second rotating disk 27 is fixedly sleeved on the second rotating shaft 28 between the support plate 105 and the counterweight base 101. A rhombus plate 25 is installed on the second rotating disk 27, and the middle of the rhombus plate 25 passes through the second rotating shaft 28. The second turntable 27 has a first arc-shaped rack 26 installed on the outer walls of both the front and rear sides. The same first turntable 23 is movably installed on the right side of the teeth at the right end of the two first arc-shaped racks 26. A first rotating shaft 22 passes through the first turntable 23. One end of the first rotating shaft 22 is connected to the output end of the drive component 21. The drive component 21 is set on the counterweight base 101. The other end of the first rotating shaft 22 is rotatably connected to the support plate 105. The first turntable 23 has the same arc-shaped tooth groove on the front outer wall that can be detachably engaged with the two first arc-shaped toothed racks 26 respectively. A pawl 24 is installed on the first turntable 23 on the right rear side of the arc-shaped tooth groove. The pawl 24 is detachably abutted and connected to both ends of the rhomboid plate 25 respectively. The connecting plate 2 drives the limiting mechanism to work through intermittent rotation, and the first rotating shaft 22 drives the rotating mechanism to work through rotation. It should be noted that the reference Figure 3 The driving component 21 drives the first rotating shaft 22 to rotate counterclockwise, the rotation of the first rotating shaft 22 drives the first turntable 23 to rotate, and the rotation of the first turntable 23 drives the lever 24 to rotate. The rotation of the paddle 24 causes the diamond plate 25 to engage one of the first arc-shaped racks 26 on the second turntable 27 with the arc-shaped tooth groove. The second turntable 27 rotates with one of the first arc-shaped racks 26. As it continues to rotate, one of the first arc-shaped racks 26 disengages from the arc-shaped tooth groove, and the second turntable 27 no longer rotates with one of the first arc-shaped racks 26. At this time, the outer wall of the first turntable 23 is stuck between two teeth of the first arc-shaped rack 26 located on the right side near the outer end of the first turntable 23, thus limiting the second turntable 27 after it rotates 180 degrees. This rotation, through the engagement and disengagement of the arc-shaped toothed grooves with the two first arc-shaped toothed racks 26, allows the second turntable 27 to rotate intermittently by 180 degrees. The intermittent rotation of the second turntable 27 drives the second rotating shaft 28 to rotate intermittently, which in turn drives the connecting plate 2 to rotate intermittently. The intermittent rotation of the connecting plate 2 drives the U-shaped plate 104 to rotate intermittently. The intermittent rotation of the U-shaped plate 104 can drive the various components installed on the U-shaped plate 104 and the air conditioner compressor housing to rotate, thereby intermittently rotating them to the laser cutting head 1 for cutting. This improves the continuity of the cutting work on the air conditioner compressor housing and enhances the efficiency of the cutting work. The limiting mechanism includes an arc-shaped clamping plate 3, a toothed ring 31, a first gear 32, a third rotating shaft 33, a rectangular plate 34, a rotating rod 35, a rectangular rod 36, a third electric push rod 37, and a rubber rotating wheel 38. Four rectangular through slots are provided on the horizontal plate of the U-shaped plate 104. A rectangular rod 36 slides through the rectangular through slots. One end of the rectangular rod 36 is hinged to the first end of the rotating rod 35. The second ends of the four rotating rods 35 located at the same end are hinged to the same rectangular plate 34. A third rotating shaft 33 moves through the rectangular plate 34. The third rotating shaft 33 is provided with a reciprocating thread. The rectangular plate 34 is threaded to the third rotating shaft 33 through the reciprocating thread. One end of the third rotating shaft 33 is rotatably connected to the horizontal plate of the U-shaped plate 104, and the other end of the third rotating shaft 33 is fixedly sleeved with a first gear 32. A toothed ring 31 is fixedly sleeved on the support plate 105, and the two first gears 32 are meshed with the same toothed ring 31. The inner side of the other end of the rectangular rod 36 is vertically connected to the fixed end of the third electric push rod 37. The telescopic end of the third electric push rod 37 is connected to the arc-shaped clamp 3. The arc-shaped clamp 3 has an installation groove, and a rubber wheel 38 is rotatably installed in the installation groove. It should be noted that, since a toothed ring 31 is fixedly sleeved on the support plate 105, the two first gears 32 are meshed with the same toothed ring 31. Furthermore, when the U-shaped plate 104 rotates 180 degrees from the right end to the left end, which is the process of moving from the picking end to the cutting end, the first gear 32 rotates. The rotation of the first gear 32 drives the third rotating shaft 33 to rotate. Since the third rotating shaft 33 is provided with a reciprocating thread, the rectangular plate 34 is threadedly connected to the third rotating shaft 33 through the reciprocating thread. The rotation of the third rotating shaft 33 drives the rectangular plate 34 to move downward. The downward movement of the rectangular plate 34 drives the second end of the rotating rod 35 to move downward. The downward movement of the second end of the rotating rod 35 drives the second end of the rotating rod 35 to move downward. One end moves inward, the first end of the rotating rod 35 moves inward, driving the rectangular rod 36 to move inward. The rectangular rod 36 moves inward, driving the third electric push rod 37 to move inward. The third electric push rod 37 moves inward, driving the arc-shaped clamping plate 3 to move inward. The arc-shaped clamping plate 3 moves inward, driving the rubber rotating wheel 38 to move inward. The rubber rotating wheel 38 moves inward, thereby centering and clamping the compressor housing, which facilitates subsequent cutting work. The picking, placing, clamping and limiting actions are linked and synchronized for coordinated operation, which is very convenient. Conversely, when the U-shaped plate 104 rotates 180 degrees from the left end to the right end, it is the process of moving from the cutting end to the picking end. That is, the rotation of the third rotating shaft 33 drives the rectangular plate 34 to move upward, which in turn drives the arc-shaped clamping plate 3 and the rubber roller 38 to move outward, thereby releasing the centering clamping limit on the compressor housing, making it easier to pick up and place, and to carry out the cutting work of the next housing. It is worth mentioning that the third electric push rod 37 is used to adjust the inner and outer extension and retraction positions of the arc-shaped clamping plate 3 and the rubber wheel 38, which facilitates the limiting of compressor housings of different diameters; the rubber wheel 38 is used to cooperate with the rotating mechanism described later to facilitate the rotation of the compressor housing; The rotating mechanism includes a placement plate 4, a third turntable 41, a second arc-shaped rack 42, a first toothed plate 43, a first spring telescopic rod 44, a first limiting plate 45, a second limiting plate 46, an L-shaped rod 47, an arc-shaped push plate 48, a second toothed plate 49, a second spring telescopic rod 410, a second gear 411, and a fourth rotating shaft 412. A rectangular groove is provided on the horizontal plate of the U-shaped plate 104 between the four rectangular through slots at the same end. One end of the fourth rotating shaft 412 is rotatably connected to the bottom wall of the rectangular groove. The other end of the fourth rotating shaft 412 is fixedly fitted with a placement plate 4. A commercially available vacuum suction cup is installed on the placement plate 4. The vacuum suction cup is used to initially fix the compressor housing. A second gear 411 is fixedly fitted on the fourth rotating shaft 412. The rear side of the second gear 411 located on the left end and the front side of the second gear 411 located on the right end are both meshed with a second tooth plate 49. One end of the second tooth plate 49 is connected to the first end of the first spring telescopic rod 44, the second end of the first spring telescopic rod 44 is connected to the side wall of the rectangular groove, and the other end of the second tooth plate 49 slides through the side wall of the rectangular groove. A second limiting plate 46 is installed on the support plate 105 on the rear side of the second rotating shaft 28. A first limiting plate 45 is installed on the support plate 105 to the right of the second limiting plate 46. The first end of the first spring telescopic rod 44 is connected to the left side of the first limiting plate 45. The first limiting plate 45 is used to install the first spring telescopic rod 44. The second end of the first spring telescopic rod 44 is connected to one end of the first toothed plate 43. The other end of the first toothed plate 43 slides through the second limiting plate 46 and is vertically connected to the end of the vertical rod of the L-shaped rod 47. The second limiting plate 46 is used to install the first toothed plate 43. The horizontal end of the L-shaped rod 47 is connected to the arc-shaped push plate 48. The arc-shaped push plate 48 is detachably connected to the other end of the two second toothed plates 49 respectively. It should be noted that when the U-shaped plate 104 rotates 180 degrees from the right end to the left end, it is the process of moving from the picking end to the cutting end. The rotation of the first rotating shaft 22 drives the third rotating disk 41 to rotate, and the rotation of the third rotating disk 41 drives the second arc-shaped rack 42 to rotate. At this time, the second arc-shaped rack 42 rotates to mesh with the first toothed plate 43, but does not drive the first toothed plate 43 to move. At the same time, the arc-shaped push plate 48 abuts against the other end of the second toothed plate 49 located on the left end. At this time, the second toothed plate 49 located on the right end will not move. The first rotating shaft 22 continues to rotate. At this time, the U-shaped plate 104 will not rotate, and the second arc-shaped rack 42 meshes with the first toothed plate 43. The rotation of the second arc-shaped rack 42 drives the first toothed plate 43 to move to the left, the first spring telescopic rod 44 is stretched, the first toothed plate 43 moves to the left, driving the L-shaped rod 47 to move to the left, the L-shaped rod 47 moves to the left, driving the arc-shaped push plate 48 to move to the left, the arc-shaped push plate 48 moves to the left, driving the second toothed plate 49 at the left end to move to the left, the second spring telescopic rod 410 is compressed, the second toothed plate 49 moves to the left, driving the second gear 411 to rotate, the second gear 411 rotates, driving the fourth rotating shaft 412 to rotate, the fourth rotating shaft 412 rotates, driving the placement plate 4 to rotate one revolution, the placement plate 4 rotates one revolution and cooperates with the laser cutting head 1 to realize the cutting work of the compressor housing, thus realizing the clamping, rotation, cutting and other operations. The work is linked together, the operation is convenient, and the linkage synchronous action is realized to improve the cutting accuracy and cutting efficiency of the compressor housing. When the placement disk 4 rotates once and cooperates with the laser cutting head 1 to cut the compressor housing, the second arc-shaped rack 42 rotates until it disengages from the first toothed plate 43, the U-shaped plate 104 rotates 180 degrees from the left end to the right end, the first spring telescopic rod 44 resets, and then the first toothed plate 43, L-shaped rod 47, and arc-shaped push plate 48 return to their initial positions. The second spring telescopic rod 410 resets, that is, the placement disk 4 and others reverse back to their initial positions, so that the cut compressor housing can be taken out and the next compressor housing can be placed. This rotation allows for cyclical cutting of the compressor housing, improving cutting efficiency. It is worth mentioning that the drive component 21 is a commercially available drive motor; It is worth mentioning that the rubber roller 38 is a commercially available damping roller. When the U-shaped plate 104 rotates 180 degrees from the right end to the left end, it is the process of moving from the picking end to the cutting end. The arc-shaped push plate 48 abuts against the other end of the second toothed plate 49 that has rotated to the left end. During this process, the rubber roller 38 will not rotate, thus ensuring the stability of the contact between the arc-shaped push plate 48 and the second toothed plate 49 that has rotated to the left end, and will not interfere with subsequent movements. It is worth mentioning that a pole is installed on the connecting plate 2 near the U-shaped plate 104, and a hook is installed on the pole. When placing the air conditioner compressor housing, the hook can connect the material handle at the port of the air conditioner compressor housing through the lifting rope. After laser cutting, the cut housing port can be easily lifted and picked up for collection. The method of using the present invention is as follows: When it is necessary to laser cut the compressor housing, the operator adjusts the first electric push rod 106, the second electric push rod 107 and the third electric push rod 37 to the appropriate position according to the size of the compressor housing, places the compressor housing on the placement plate 4 on the right end and initially fixes it with a vacuum suction cup, and drives the drive component 21. The driving component 21 drives the first rotating shaft 22 to rotate counterclockwise, and the rotation of the first rotating shaft 22 drives the first turntable 23 to rotate, and the rotation of the first turntable 23 drives the lever 24 to rotate. The rotation of the paddle 24 causes the diamond plate 25 to engage one of the first arc-shaped racks 26 on the second turntable 27 with the arc-shaped tooth groove. The second turntable 27 rotates with one of the first arc-shaped racks 26. As it continues to rotate, one of the first arc-shaped racks 26 disengages from the arc-shaped tooth groove, and the second turntable 27 no longer rotates with one of the first arc-shaped racks 26. At this time, the outer wall of the first turntable 23 is stuck between two teeth of the first arc-shaped rack 26 located on the right side near the outer end of the first turntable 23, thus limiting the second turntable 27 after it rotates 180 degrees. This rotation, through the engagement and disengagement of the arc-shaped toothed grooves with the two first arc-shaped toothed racks 26, allows the second turntable 27 to rotate intermittently by 180 degrees. The intermittent rotation of the second turntable 27 drives the second rotating shaft 28 to rotate intermittently, which in turn drives the connecting plate 2 to rotate intermittently. The intermittent rotation of the connecting plate 2 drives the U-shaped plate 104 to rotate intermittently. The intermittent rotation of the U-shaped plate 104 can drive the various components installed on the U-shaped plate 104 and the air conditioner compressor housing to rotate, thereby intermittently rotating them to the laser cutting head 1 for cutting. This improves the continuity of the cutting work on the air conditioner compressor housing and enhances the efficiency of the cutting work. Simultaneously, when the U-shaped plate 104 rotates 180 degrees from the right end to the left end, it moves from the picking end to the cutting end, causing the first gear 32 to rotate. The rotation of the first gear 32 drives the third rotating shaft 33 to rotate. Since the third rotating shaft 33 is provided with a reciprocating thread, the rectangular plate 34 is threadedly connected to the third rotating shaft 33 through the reciprocating thread. This causes the third rotating shaft 33 to rotate, driving the rectangular plate 34 to move downwards. The downward movement of the rectangular plate 34 drives the second end of the rotating rod 35 to move downwards, and the downward movement of the second end of the rotating rod 35 drives the second end of the rotating rod 35 to move downwards. One end moves inward, the first end of the rotating rod 35 moves inward, driving the rectangular rod 36 to move inward. The rectangular rod 36 moves inward, driving the third electric push rod 37 to move inward. The third electric push rod 37 moves inward, driving the arc-shaped clamping plate 3 to move inward. The arc-shaped clamping plate 3 moves inward, driving the rubber rotating wheel 38 to move inward. The rubber rotating wheel 38 moves inward, thereby centering and clamping the compressor housing, which facilitates subsequent cutting work. The picking, placing, clamping and limiting actions are linked and synchronized for coordinated operation, which is very convenient. Conversely, when the U-shaped plate 104 rotates 180 degrees from the left end to the right end, it is the process of moving from the cutting end to the picking end. That is, the rotation of the third rotating shaft 33 drives the rectangular plate 34 to move upward, which in turn drives the arc-shaped clamping plate 3 and the rubber roller 38 to move outward, thereby releasing the centering clamping limit on the compressor housing, making it easier to pick up and place, and to carry out the cutting work of the next housing. Meanwhile, when the U-shaped plate 104 rotates 180 degrees from the right end to the left end, it is the process of moving from the picking end to the cutting end. The rotation of the first rotating shaft 22 drives the third rotating disk 41 to rotate, and the rotation of the third rotating disk 41 drives the second arc-shaped rack 42 to rotate. At this time, the second arc-shaped rack 42 rotates to mesh with the first toothed plate 43, but does not drive the first toothed plate 43 to move. At the same time, the arc-shaped push plate 48 abuts against the other end of the second toothed plate 49 located on the left end. At this time, the second toothed plate 49 located on the right end will not move. The first rotating shaft 22 continues to rotate. At this time, the U-shaped plate 104 will not rotate, and the second arc-shaped rack 42 meshes with the first toothed plate 43. The rotation of the second arc-shaped rack 42 drives the first toothed plate 43 to move to the left, the first spring telescopic rod 44 is stretched, the first toothed plate 43 moves to the left, driving the L-shaped rod 47 to move to the left, the L-shaped rod 47 moves to the left, driving the arc-shaped push plate 48 to move to the left, the arc-shaped push plate 48 moves to the left, driving the second toothed plate 49 at the left end to move to the left, the second spring telescopic rod 410 is compressed, the second toothed plate 49 moves to the left, driving the second gear 411 to rotate, the second gear 411 rotates, driving the fourth rotating shaft 412 to rotate, the fourth rotating shaft 412 rotates, driving the placement plate 4 to rotate one revolution, the placement plate 4 rotates one revolution and cooperates with the laser cutting head 1 to realize the cutting work of the compressor housing, thus realizing the clamping, rotation, cutting and other operations. The work is linked together, the operation is convenient, and the linkage synchronous action is realized to improve the cutting accuracy and cutting efficiency of the compressor housing. When the placement disk 4 rotates once and cooperates with the laser cutting head 1 to cut the compressor housing, the second arc-shaped rack 42 rotates until it disengages from the first toothed plate 43. The U-shaped plate 104 then rotates 180 degrees from the left end to the right end. The first spring telescopic rod 44 returns to its original position, and then the first toothed plate 43, L-shaped rod 47, and arc-shaped push plate 48 return to their initial positions. The second spring telescopic rod 410 also returns to its original position, and the placement disk 4 and the others reverse back to their initial positions. The cut compressor housing can then be removed, and the next compressor housing can be placed. This rotation allows for cyclical cutting of the compressor housing, improving cutting efficiency.

[0017] This invention, through the coordinated use of intermittent, limiting, and rotating mechanisms, enables the rotation of components mounted on the U-shaped plate and the air conditioner compressor housing. This allows for intermittent rotation to the laser cutting head for cutting, improving the continuity and efficiency of the cutting process. Furthermore, the centering and clamping of the compressor housing facilitates subsequent cutting operations. The simultaneous and coordinated actions of picking, placing, and clamping provide enhanced convenience. The rotation of the placement plate, in conjunction with the laser cutting head, completes the cutting of the compressor housing. This interconnected operation of clamping, rotating, and cutting enhances the cutting accuracy and efficiency of the compressor housing. Finally, the invention enables cyclical cutting of the compressor housing, further improving overall cutting efficiency. This invention has a simple and reliable structure, provides good laser cutting effect on the port of the air conditioner compressor housing, is easy to control, and is suitable for widespread application.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
