Description

Technical Field

[0001] This utility model relates to the field of air conditioning four-way valve technology, specifically to a chamfering device for an air conditioning four-way valve. Background Technology

[0002] The four-way valve is an essential component in air conditioners that can switch between cooling and heating functions by changing the flow of refrigerant. When processing the four-way valve, the port needs to be chamfered. However, the existing chamfering devices are complex in structure, and special equipment is required for the shape and model of the four-way valve. Furthermore, after processing one port, manual adjustment is required to process it again, which greatly affects the processing efficiency and cannot achieve universality for workpieces of different sizes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a chamfering device for an air conditioning four-way valve. It has a simple structure and is easy to operate. It can not only process four-way valves of different models, but also process workpieces of different shapes. It is more convenient to use and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chamfering device for an air conditioning four-way valve, comprising a support platform, a rotating platform rotatably connected to the upper surface of the support platform, and a servo motor II for driving the rotating platform to rotate mounted on the lower surface of the support platform. A lower workpiece positioning seat is fixed at the upper end of the rotating platform, and a clamping drive component is fixed on one side of the upper surface of the support platform. An upper workpiece positioning seat is rotatably connected to the clamping drive component. Two tracks I are provided on the upper surface of the support platform, and front and rear sliding seats are slidably connected on the two tracks I. A front and rear adjusting component for driving the front and rear sliding seats to move back and forth is provided on the support platform. Two tracks II are provided on the upper surface of the front and rear sliding seats, and left and right sliding seats are slidably connected on the two tracks II. A feed cylinder for driving the left and right sliding seats to slide is connected to the upper surface of the front and rear sliding seats through a cylinder seat. An external chamfering chip structure is provided on the upper surface of the left and right sliding seats.

[0005] Furthermore, the lower workpiece positioning seat and the upper workpiece positioning seat are vertically aligned, and each of the lower workpiece positioning seat and the upper workpiece positioning seat has a groove corresponding to the workpiece on its opposite side. The workpiece is clamped and fixed by the groove, thereby preventing the workpiece from rotating during chamfering.

[0006] Furthermore, the clamping drive component includes an L-shaped support fixed to the upper surface of the support platform. A telescopic cylinder is fixed to the upper end of the L-shaped support. The telescopic end of the telescopic cylinder is connected to the upper workpiece positioning seat through a bearing. By extending the telescopic cylinder, the upper workpiece positioning seat can be moved downward. By moving the upper workpiece positioning seat downward, the workpiece can be fixed to the upper surface of the lower workpiece positioning seat.

[0007] Furthermore, the front and rear adjustment components include an adjustment screw connected to the upper surface of the support platform via a bracket. The adjustment screw is connected to the front and rear sliding seats via a threaded connection. The bracket is equipped with a servo motor that drives the adjustment screw to rotate. The rotation of the servo motor can drive the adjustment screw to rotate, which in turn can drive the front and rear sliding seats to move back and forth. This can drive the external chamfering chip structure to move, thereby adjusting the four-way valve with a tree-like structure during processing, thus meeting the processing requirements of four-way valves with different shapes.

[0008] Furthermore, the external chamfering chip structure includes a cutting motor fixed to the upper surface of the left and right sliding seats. A barrel-shaped tool holder is fixed to the output end of the cutting motor. Cutting blades are evenly fixed to the barrel-shaped tool holder by screws. The cutting blades are inclined so that they can process four-way valves of different diameters. During processing, the axis of the barrel-shaped tool holder and the port axis of the four-way valve are on the same straight line. The operation of the cutting motor can drive the barrel-shaped tool holder to rotate, and the rotation of the barrel-shaped tool holder can drive the cutting blades to rotate. The rotation of the cutting blades can be used to chamfer the port of the four-way valve.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the chamfering device for the four-way valve of the air conditioner has the following advantages:

[0010] 1. This utility model uses a telescopic cylinder to extend, which can drive the upper workpiece positioning seat to move downward. The downward movement of the upper workpiece positioning seat can fix the workpiece to the upper surface of the lower workpiece positioning seat. The grooves on the upper and lower workpiece positioning seats are used to lock and fix the workpiece, thereby preventing the workpiece from rotating during chamfering.

[0011] 2. This utility model uses a servo motor to drive an adjusting screw, which in turn moves the front and rear sliding seats back and forth, thereby moving the outer chamfering chip structure. This allows for adjustment during the processing of a tree-shaped four-way valve, thus satisfying the processing needs of four-way valves of different shapes.

[0012] 3. This utility model uses an extended feed cylinder to move left and right sliding seats, which in turn move the outer chamfering chip structure. Simultaneously with the feed, the cutting motor rotates the barrel-shaped tool holder, which in turn rotates the cutting tool. This rotation of the cutting tool then chamfers the port of the four-way valve. This chamfering device for air conditioning four-way valves has a simple structure and is easy to operate. It can process not only different models of four-way valves but also workpieces of different shapes, making it more convenient to use. Attached Figure Description

A lower workpiece positioning seat 3 is fixed to the upper end of the rotating platform 2, and a clamping drive member 7 is fixed to one side of the upper surface of the support platform 1. An upper workpiece positioning seat 4 is rotatably connected to the clamping drive member 7. Two tracks 1 9 are provided on the upper surface of the support platform 1, and front and rear sliding seats 12 are slidably connected on the two tracks 1 9. A front and rear adjusting member 6 for driving the front and rear sliding seats 12 to move back and forth is provided on the support platform 1. Two tracks 2 10 are provided on the upper surface of the front and rear sliding seats 12, and two tracks 2 10 are provided on the two tracks 2 10. The left and right sliding seats 11 are slidably connected, and the upper surfaces of the front and rear sliding seats 12 are connected to the feed cylinder 5, which drives the left and right sliding seats 11 to slide, via a cylinder seat. The upper surfaces of the left and right sliding seats 11 are provided with an external chamfering chip structure 8. The lower workpiece positioning seat 3 and the upper workpiece positioning seat 4 are vertically aligned. The lower workpiece positioning seat 3 and the upper workpiece positioning seat 4 are provided with grooves corresponding to the workpiece on opposite sides. The workpiece is clamped and fixed by the grooves, thereby preventing the workpiece from rotating during chamfering. The fastening drive component 7 includes an L-shaped support 72 fixed to the upper surface of the support table 1. A telescopic cylinder 71 is fixed to the upper end of the L-shaped support 72. The telescopic end of the telescopic cylinder 71 is connected to the upper workpiece positioning seat 4 via a bearing. By extending the telescopic cylinder 71, the upper workpiece positioning seat 4 can be driven to move towards the upper workpiece positioning seat 4. The workpiece can be fixed to the upper surface of the lower workpiece positioning seat 3 by moving the upper workpiece positioning seat 4 downward. The front and rear adjustment component 6 includes an adjustment screw 62 connected to the upper surface of the support table 1 through a support. The adjustment screw 62 is connected to the front and rear sliding seats 12 by a threaded connection. The support is equipped with a servo motor 61 that drives the adjustment screw 62 to rotate. The rotation of the servo motor 61 drives the adjustment screw 62 to rotate. The rotation of the adjustment screw 62 drives the front and rear sliding seats 12 to move back and forth, thereby driving the external chamfering chip structure 8 to move. This allows for adjustment during the processing of the tree-shaped four-way valve, thus meeting the processing requirements of four-way valves of different shapes. The external chamfering chip structure 8 includes a cutting element fixed to the upper surface of the left and right sliding seats 11. The output end of the cutting motor 82 is fixed with a barrel-shaped tool holder 81. Cutting blades 83 are evenly fixed on the barrel-shaped tool holder 81 by screws. The cutting blades 83 are inclined, which allows for the processing of four-way valves of different diameters. During processing, the axis of the barrel-shaped tool holder 81 is kept on the same straight line as the axis of the port of the four-way valve. The operation of the cutting motor 82 drives the barrel-shaped tool holder 81 to rotate, which in turn drives the cutting blades 83 to rotate. The rotation of the cutting blades 83 can chamfer the port of the four-way valve. This chamfering device for air conditioning four-way valves has a simple structure and is easy to operate. It can process not only different models of four-way valves, but also workpieces of different shapes, making it more convenient to use.

[0019] In use: First, select suitable upper workpiece positioning seat 4 and lower workpiece positioning seat 3 for installation. Then, the four-way valve is extended by the telescopic cylinder 71, which moves the upper workpiece positioning seat 4 downward. This downward movement of the upper workpiece positioning seat 4 fixes the workpiece to the upper surface of the lower workpiece positioning seat 3. The grooves on the upper and lower workpiece positioning seats 4 and 3 secure the workpiece, preventing rotation during chamfering. The rotation of the servo motor 13 drives the rotating table 2, which in turn rotates the upper workpiece positioning seat 4, lower workpiece positioning seat 3, and four-way valve, aligning the processing port of the four-way valve with the front and rear adjusting parts 6. The rotation of machine 61 drives the adjustment screw 62 to rotate, which in turn drives the front and rear sliding seats 12 to move back and forth, thereby moving the outer chamfering chip structure 8. This allows for adjustment during the machining of the tree-shaped four-way valve, thus satisfying the machining needs of four-way valves of different shapes. During machining, the extension of the feed cylinder 5 drives the left and right sliding seats 11 to move, which in turn drives the outer chamfering chip structure 8 to move. Simultaneously with the feed, the operation of the cutting motor 82 drives the barrel-shaped tool holder 81 to rotate, which in turn drives the cutting tool 83 to rotate. The rotation of the cutting tool 83 allows for chamfering of the four-way valve port.
