Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and processing technology, specifically to a central air conditioning muffler chamfering processing equipment. Background Technology

[0002] In central air conditioning systems, silencers are key components for reducing noise transmission. As modern building environments increasingly demand higher acoustic comfort, optimizing the performance of central air conditioning silencers has become increasingly important. This involves the chamfering of the silencer's inner corners, thus creating a demand for specialized processing equipment.

[0003] Chinese patent CN 216607505 U discloses a semi-automatic air conditioner muffler chamfering machine. The key technical features include: a worktable with a base frame fixedly connected below it; a rear top frame at the top center of the worktable's rear side; a limit plate fixedly installed on the bottom inner side of the feeding plate; a bearing seat at the top center of the worktable; a shaft fixedly connected to the feeding disc at its center; and a first motor fixedly connected to the right end of the shaft; a slide located on the front side of the worktable, with a chamfering drill body mounted on the rear side of the second motor; and a discharge plate located below the front side of the feeding disc, with a front top frame on the left rear end of the discharge plate. This semi-automatic air conditioner muffler chamfering machine facilitates the transmission of the air conditioner muffler tube, simplifying its processing and clamping, thus enabling mass production and improving efficiency.

[0004] Existing chamfering processing devices achieve chamfering through the combined use of a motor and a chamfering head. However, after processing a workpiece, the chamfering device needs to be manually reset, resulting in low production efficiency, increased manual labor, and reduced practicality of the chamfering processing device. Utility Model Content

[0005] This utility model provides a central air conditioning muffler chamfering processing equipment, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a central air conditioning muffler chamfering processing device, comprising:

[0008] Support plate;

[0009] The feed inlet is fixedly installed at the top center of the rear side of the support plate;

[0010] The support frame is fixedly installed on the outer surface of the support plate;

[0011] The feeding tray is installed through the inner end of the support frame for feeding materials;

[0012] The sliding plate is slidably connected to the groove on the upper surface of the support plate;

[0013] The chamfering device is fixedly installed on the upper surface of the sliding plate;

[0014] The slider is fixedly connected at one end to the lower end of the chamfering device and slides around the reciprocating lead screw.

[0015] The reciprocating lead screw has one end threadedly connected to the output end of the second motor and passes through the connecting block;

[0016] The second motor is fixedly connected to one end inside the support plate;

[0017] The fixing block is fixedly connected to the upper part of the support plate.

[0018] Through the above technical solution, the cooperation of the second motor, reciprocating lead screw and slider enables the slider to drive the chamfering device to move back and forth, achieving cyclic operation.

[0019] Furthermore, the chamfering device includes a first motor, the output end of which is rotatably connected to a belt for driving the connecting rod to rotate, and one end of the connecting rod is threadedly connected to a chamfering drill bit.

[0020] The above technical solution connects the belt to the first motor, and the first motor drives the connecting rod and the chamfering drill bit to rotate, thereby chamfering the workpiece.

[0021] Furthermore, the slider has a rotatable block inside that matches the bidirectional helical groove on the reciprocating lead screw.

[0022] By using the above technical solution and the rotatable block inside the slider, the slider can achieve reciprocating translational motion, further improving the practicality of the equipment.

[0023] Furthermore, a gear disk is fixedly connected to one end of the feeding disc, and the gear disk meshes with a single tooth protruding on the single gear. One side of the single gear is fixedly connected to the output end of the servo motor, and a limit device is provided on one side of the gear disk.

[0024] The above technical solution connects the gear disk to the single gear through meshing, allowing the gear disk to drive the feeding disk to rotate intermittently while waiting for the chamfering device to process it, thus further improving the practicality of the equipment. The setting of the limit device can restrict the rotation direction of the gear disk and prevent the gear disk from reversing and shaking during workpiece processing.

[0025] Furthermore, the feeding tray has a groove with the same size as the workpiece, and a baffle is attached to the upper surface of the feeding tray. The baffle is fixedly connected to the upper inner side of the support frame.

[0026] The above technical solution, with the baffle, can fix the workpiece in the feeding tray and prevent it from shaking during processing.

[0027] Furthermore, a guide plate is fixedly connected to the upper part of the feed inlet.

[0028] The above technical solution, through the setting of the guide plate, can restrict the sliding posture of the workpiece and prevent the workpiece from tilting and blocking.

[0029] The above-described solution of this utility model has at least the following beneficial effects:

[0030] 1. In this utility model, through the coordinated operation of the second motor, the reciprocating lead screw, the slider and the chamfering device, when the second motor drives the reciprocating lead screw to rotate, the slider makes a translational movement, thereby driving the chamfering device to perform chamfering operation on the workpiece. When the slider moves to the end of the reciprocating lead screw, it can return by means of the reverse groove. This cycle of operation reduces the amount of manual labor, improves production efficiency, realizes automated production, and further improves the practicality of the equipment.

[0031] 2. This utility model, through the coordinated operation of a servo motor, a single gear, a gear disk, and a feeding disk, enables the feeding disk to rotate intermittently when the servo motor drives the single gear to rotate, thanks to the design features of the single gear. After the chamfering device completes the processing of the workpiece, the feeding disk can transport the workpiece. This mechanism realizes automated production and further improves the practicality of the equipment. Attached Figure Description

[0039] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0040] like Figures 1 to 5 As shown, an embodiment of this utility model provides a central air conditioning muffler chamfering processing device, comprising: a support plate 1; a support leg 2 fixedly connected to the lower end of the support plate 1; a feed inlet 3 fixedly installed at the top center of the rear side of the support plate 1; a support frame 4 fixedly installed on the outer surface of the support plate 1; a feeding tray 5, which is installed through the inner end of the support frame 4 for feeding materials; a discharge tray 13 fitted to the surface of the feeding tray 5; and a sliding plate 12 slidably connected to the support plate 1. The support plate 1 has a groove on its upper surface; a chamfering device 6 is fixedly installed on the upper surface of the sliding plate 12; a slider 14 is fixedly connected at one end to the lower end of the chamfering device 6 and slides around the reciprocating shaft lead screw 15; the reciprocating shaft lead screw 15 is threaded at one end to the output end of the second motor 16 and passes through the fixing block 17; the second motor 16 is fixedly connected to one end inside the support plate 1; and the fixing block 17 is fixedly connected to the upper end inside the support plate 1.

[0041] In this embodiment, the reciprocating lead screw 15 is connected to the second motor 16 by a threaded connection. When the second motor 16 starts, it drives the reciprocating lead screw 15 to rotate, thereby driving the slider 14 to slide, so that the chamfering device 6 chamfers the workpiece forward.

[0042] like Figure 4 As shown, the chamfering device 6 includes a first motor 61, the output end of which is rotatably connected to a belt 62 for driving the connecting rod 63 to rotate, and one end of the connecting rod 63 is threadedly connected to a chamfering drill bit 64.

[0043] In this embodiment, the first motor 61 is connected to the belt 62 by a rotating connection. When the first motor 61 is started, the belt 62 drives the connecting rod 63 to rotate, and at this time the chamfering drill bit 64 chamfers the workpiece.

[0044] like Figures 2 to 4 As shown, the slider 14 has a rotatable block inside that matches the bidirectional helical groove on the reciprocating lead screw 15.

[0045] In this embodiment, the rotatable block inside the slider 14 matches the bidirectional spiral groove on the reciprocating screw 15, causing the reciprocating screw 15 to rotate and drive the slider 14 to translate. When the slider 14 moves to one end of the reciprocating screw 15, the block enters the reverse groove to return.

[0046] In this embodiment of the invention (working principle), after the first motor 61 starts, it drives the connecting rod 63 to rotate via the belt 62, which in turn drives the chamfering drill bit 64 to rotate. The rotation of the chamfering drill bit 64 is used to chamfer the workpiece. At the same time, the second motor 16 is driven to rotate, which allows the slider 14 to slide horizontally, thereby driving the sliding plate 12 to slide forward. During this process, the chamfering device 6 processes the workpiece. As the rotatable block inside the slider 14 enters the reverse groove under the action of the groove on the reciprocating lead screw 15, the slider 14 moves back horizontally, thus repeating the processing work cyclically.

[0047] like Figures 1 to 5 As shown, a gear disk 9 is fixedly connected to one end of the feeding disk 5. The gear disk 9 meshes with a single tooth protruding on the single gear 8. One side of the single gear 8 is fixedly connected to the output end of the servo motor 7. A limit device 10 is provided on one side of the gear disk 9.

[0048] In this embodiment, the single gear 8 and the gear disk 9 are connected by meshing. When the servo motor 7 starts, it drives the single gear 8 to rotate. Due to the design features of the single gear 8, the gear disk 9 rotates in stages. The limiting device 10 is composed of a tooth block rotatably set on one side of the gear disk 9. The size of the tooth block is adapted to the size of the tooth groove of the gear disk 9, and is used to limit the gear disk.

[0049] like Figure 5 As shown, the feeding tray 5 has a groove with the same size as the workpiece, and a baffle 11 is attached to the upper surface of the feeding tray 5. The baffle 11 is fixedly connected to the upper inner side of the support frame 4.

[0050] In this embodiment, the feeding tray 5 and the baffle 11 are connected by a bonding connection. The baffle 11 can bond the workpiece to prevent it from falling off.

[0051] In this embodiment of the invention, the workpiece is placed at the feed inlet 3 and slides into the inner groove of the feeding tray 5 under its own gravity. The servo motor 7 starts and drives the single gear 8 to rotate. Due to the specific design features of the single gear 8, the gear disk 9 rotates in stages. After the chamfering device 6 completes the processing of the workpiece, it pushes the gear disk 9 to rotate, which in turn drives the feeding tray 5 to rotate, thus commencing the processing of the next workpiece. Simultaneously, the baffle 11 adheres to the workpiece to prevent it from slipping.

[0052] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
