Description

Technical Field

[0001] This utility model relates to the field of valve assembly technology, and in particular to a clamping device for assembling air conditioning valves. Background Technology

[0002] Air conditioning valves are key components in air conditioning systems, controlling refrigerant flow and regulating pressure and flow rate. They come in various types, such as shut-off valves, solenoid valves, and expansion valves. Shut-off valves are used to cut off or connect refrigerant lines; solenoid valves control the valve opening and closing via electromagnetic force, achieving precise control of the refrigeration system; expansion valves throttle and reduce the pressure of high-pressure liquid refrigerant, transforming it into a low-pressure mist, which facilitates subsequent evaporation and heat absorption. Air conditioning valve assembly is the process of orderly combining and installing various valve components. It must be carried out strictly according to design requirements and process flows to ensure tight connections, precise positioning, and good sealing of all components to prevent refrigerant leakage. During assembly, the valve's opening and closing flexibility and flow regulation performance must be tested to ensure normal operation in the air conditioning system, thereby effectively regulating refrigerant circulation and achieving the air conditioning's cooling and heating functions.

[0003] In the process of assembling air conditioning valves, in order to avoid valve displacement, free up hands, and improve assembly convenience, valve clamping equipment is often used to assemble air conditioning valves. Existing air conditioning valve clamping equipment is mostly of a relatively fixed structure, such as a simple mechanical clamping structure or a specific shaped frame combined with a cylinder or electric telescopic clamping plate structure. Although this structure can clamp specific valve components, its two-sided clamping method makes it difficult to clamp irregularly shaped components. Furthermore, the clamping range of existing clamping equipment is limited by the movement stroke of the clamping part, making it difficult to clamp valve components of various sizes. It is also difficult to perform internal or external clamping according to the actual needs of installation. Air conditioning systems have various valves such as shut-off valves, solenoid valves, expansion valves, and check valves. These valves have different shapes and specifications, so existing valve clamping equipment is difficult to apply to the assembly of air conditioning valves.

[0004] Therefore, there is an urgent need to provide a clamping device for assembling air conditioning valves to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a clamping device for assembling air conditioning valves.

[0006] To solve the above-mentioned technical problems, the present invention provides a clamping device for assembling air conditioning valves, including an installation mechanism and a clamping mechanism. A transmission mechanism is rotatably connected to the installation mechanism, and a turntable mechanism is also rotatably connected to the installation mechanism. Multiple cylinder mechanisms are fixed on the turntable mechanism.

[0007] A clamping mechanism is movably connected to the inner side of the cylinder mechanism;

[0008] The bottom end of the transmission mechanism is connected to a drive mechanism for driving the turntable to rotate.

[0009] The present invention is further configured such that: the mounting mechanism includes a base plate, a plurality of fixing bolt groups are provided on the base plate, a protective cover is fixed on the base plate, and a bearing is also fixed on the base plate.

[0010] Through the above technical solution, the workers can fix the base plate to the workbench using the bearing, thereby preventing the device from shifting under force when assembling the air conditioning valve and improving the stability of the device.

[0011] The present invention is further configured such that: the transmission mechanism includes a second bearing fixed to the inner side of the base plate, an inner hexagonal sleeve fixed on the inner ring of the second bearing, and a drive gear fixed to the top of the inner hexagonal sleeve.

[0012] With the above technical solution, the drive gear and the internal hexagonal sleeve are coaxially fixed, and the drive gear and the internal hexagonal sleeve can rotate relative to the bearing.

[0013] The present invention is further configured such that: the turntable mechanism includes a rotating shaft fixed to an inner ring of a bearing, a driven gear is fixed to the top of the rotating shaft, an integrated air circuit plate is fixed to the top of the driven gear, an anti-edge structure is integrally fixed to the outer side of the integrated air circuit plate, and a positioning platform and a reversing valve are also fixed to the top of the integrated air circuit plate.

[0014] Through the above technical solution, the reversing valve can be connected to an external high-pressure air source. The integrated air circuit board has two non-interfering airflow channels. The two ports of the reversing valve are connected to these two airflow channels respectively. The anti-edge structure cooperates with the protective cover to effectively prevent foreign objects from entering the protective cover and affecting the gear transmission. The positioning platform can be used to place valve components.

[0015] The present invention is further configured such that: the cylinder mechanism includes a connecting part fixed to the top of the integrated air circuit board, a cylinder body is fixed to the top of the connecting part, sealing rings are fixed to both ends of the cylinder body, and two air inlet and outlet pipes are also sealed and connected to the cylinder body.

[0016] Through the above technical solution, multiple cylinder mechanisms are arranged in a ring-shaped equidistant array, with openings at both ends of the cylinder body. The sealing ring can effectively ensure the airtightness of the cylinder body, and the two inlet and outlet pipes are respectively connected to two airflow channels in the integrated air circuit board.

[0017] The present invention is further configured such that: the clamping mechanism includes a sliding piston movably disposed inside the cylinder body, a piston rod is fixed to the inner side of the sliding piston, a clamping block one is fixed to one end of the piston rod, a clamping contact one and a clamping contact two are fixed on the clamping block one, and a clamping block two is fixed to the other end of the piston rod.

[0018] Through the above technical solution, the sliding piston divides the cylinder into two parts. When one end of the cylinder is filled with air, the sliding piston moves to the other end, thereby driving the piston rod to move to that end. The piston rod is through-type, and the clamping blocks one and two at its two ends can clamp valve components of different specifications. The clamping contacts one and two are located on the inner and outer sides of the clamping block one, respectively, so that the clamping block one can clamp externally and internally. The clamping block two has the same structure as the clamping block one, which effectively improves the applicability of the device.

[0019] The present invention is further configured such that: the driving mechanism includes a hexagonal prism inserted into the inner side of the internal hexagonal sleeve, an output shaft is fixed at the bottom end of the hexagonal prism, a servo motor is rotatably connected to the bottom end of the output shaft, and a plurality of screw lugs are fixed on the servo motor.

[0020] Through the above technical solution, the servo motor can be fixed to the bottom of the worktable with screw lugs, thereby reducing obstructions on the worktable and avoiding interference with the assembly operation. The specifications of the hexagonal prism and the internal hexagonal socket are matched. Both the hexagonal prism and the internal hexagonal socket are relatively long, so the distance between the transmission mechanism and the drive mechanism can be changed according to the thickness of the worktable. When the servo motor is started, the output shaft will rotate, thereby driving the hexagonal prism to rotate. The hexagonal prism drives the internal hexagonal socket and the drive gear to rotate. The drive gear meshes with the driven gear. When the drive gear rotates, it can drive the driven gear and the integrated air circuit board to rotate, thereby making the workpiece rotate, which facilitates the assembly work of the operator. The servo motor can effectively limit the number of forward and reverse rotations of the integrated air circuit board to within one revolution, thereby avoiding the entanglement of the external airflow hose.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model achieves ring-parallel pneumatic clamping through the setting of cylinder mechanism and clamping mechanism, which can clamp irregularly shaped valve parts, improve its applicability, and its cylinder output shaft is through type, both ends of which can be externally or internally supported and clamped, further improving the applicability of the device.

[0023] 2. By setting up an installation mechanism, a transmission mechanism, a turntable mechanism, and a drive mechanism, this utility model enables the device to rotate at a specified angle when clamping, and its drive part is located below the tabletop, reducing obstruction to the workpiece.

Detailed Implementation

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Please see Figures 1-7A clamping device for assembling air conditioning valves includes an installation mechanism 1 and a clamping mechanism 5. The installation mechanism 1 includes a base plate 101, on which multiple fixing bolt groups 102 are passed. A protective cover 103 is fixed on the base plate 101, and a bearing 104 is also fixed on the base plate 101. The operator can fix the base plate 101 to the workbench through the bearing 104, thereby preventing the device from shifting under force when assembling air conditioning valves and improving the stability of the device. A transmission mechanism 2 is rotatably connected to the installation mechanism 1. The transmission mechanism 2 includes a bearing 201 fixed to the inner side of the base plate 101. An internal hexagonal sleeve 202 is fixed on the inner ring of the bearing 201. A drive gear 203 is fixed to the top of the internal hexagonal sleeve 202. The drive gear 203 and the internal hexagonal sleeve 202 are coaxially fixed. The drive gear 203 and the internal hexagonal sleeve 202 can rotate relative to the bearing 201.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, a turntable mechanism 3 is also rotatably connected to the mounting mechanism 1. The turntable mechanism 3 includes a rotating shaft 301 fixed to the inner ring of the bearing 104. A driven gear 302 is fixed to the top of the rotating shaft 301. An integrated air circuit plate 303 is fixed to the top of the driven gear 302. A reverse edge structure 304 is integrally fixed to the outer side of the integrated air circuit plate 303. A positioning platform 305 and a reversing valve 306 are also fixed to the top of the integrated air circuit plate 303. The reversing valve 306 can be connected to an external high-pressure air source. The integrated air circuit plate 303 has two non-interfering airflow channels inside. The two ports of the reversing valve 306 are respectively connected to these two airflow channels. The reverse edge structure 304 cooperates with the protective cover 103 to effectively prevent interference. To prevent foreign objects from entering the protective cover 103 and affecting the gear transmission, the positioning platform 305 can be used to place valve components. Multiple cylinder mechanisms 4 are fixed on the turntable mechanism 3. Each cylinder mechanism 4 includes a connecting part 401 fixed to the top of the integrated air circuit board 303. A cylinder body 402 is fixed to the top of the connecting part 401. Both ends of the cylinder body 402 are fixed with sealing rings 403. Two air inlet and outlet pipes 404 are also sealed and connected to the cylinder body 402. The multiple cylinder mechanisms 4 are arranged in a ring equidistant array. Both ends of the cylinder body 402 are provided with openings. The sealing rings 403 can effectively ensure the airtightness of the cylinder body 402. The two air inlet and outlet pipes 404 are respectively connected to two airflow channels in the integrated air circuit board 303.

[0035] like Figure 1 and Figure 6As shown, a clamping mechanism 5 is movably connected to the inner side of the cylinder mechanism 4. The clamping mechanism 5 includes a sliding piston 501 movably disposed inside the cylinder body 402. A piston rod 502 is fixed to the inner side of the sliding piston 501. A clamping block 503 is fixed to one end of the piston rod 502. A clamping contact 504 and a clamping contact 505 are fixed on the clamping block 503. A clamping block 506 is fixed to the other end of the piston rod 502. The sliding piston 501 divides the cylinder body 402 into two parts. When one end of the cylinder body 402 is inflated... The sliding piston 501 moves to the other end, thereby driving the piston rod 502 to move to that end. The piston rod 502 is a through-type piston rod, and the clamping blocks 503 and 506 at both ends can clamp valve components of different specifications. The clamping contacts 504 and 505 are located on the inner and outer sides of the clamping block 503, respectively, so that the clamping block 503 can clamp externally and internally. The clamping block 506 has the same structure as the clamping block 503, which effectively improves the applicability of the device.

[0036] like Figure 1 and Figure 7 As shown, a drive mechanism 6 for driving the turntable to rotate is inserted into the bottom end of the transmission mechanism 2. The drive mechanism 6 includes a hexagonal prism 601 inserted into the inner side of the hexagonal socket 202. An output shaft 602 is fixed to the bottom end of the hexagonal prism 601. A servo motor 603 is rotatably connected to the bottom end of the output shaft 602. Multiple screw ears 604 are fixed on the servo motor 603. The servo motor 603 can be fixed to the bottom of the worktable through the screw ears 604, thereby reducing obstructions on the worktable and avoiding interference with the assembly operation. The hexagonal prism 601 and the hexagonal socket 202 are matched in specifications. Both the hexagonal prism 601 and the hexagonal socket 202 are relatively long, therefore the transmission... The distance between mechanism 2 and drive mechanism 6 can be changed according to the thickness of the table. When the servo motor 603 is started, the output shaft 602 will rotate, thereby driving the hexagonal prism 601 to rotate. The hexagonal prism 601 drives the inner hexagonal sleeve 202 and the drive gear 203 to rotate. The drive gear 203 meshes with the driven gear 302. When the drive gear 203 rotates, it can drive the driven gear 302 and the integrated air circuit board 303 to rotate, thereby causing the workpiece to rotate, which facilitates the assembly work of the workers. The servo motor 603 can effectively limit the number of forward and reverse rotations of the integrated air circuit board 303 to within one revolution, thereby avoiding the entanglement of the external airflow hose.

[0037] In use, the operator first drills bolt holes and transmission through holes on the workbench, and then fixes the device on the workbench through the installation mechanism 1. When the operator needs to clamp the valve component, the valve can be placed on the positioning platform 305 and the external air source can be turned on. At this time, the clamping mechanism 5 will clamp the valve component, which makes it easier for the operator to assemble the valve. During assembly, the operator can control the turntable mechanism 3 to rotate a certain angle through the servo motor 603, thereby adjusting the direction of the valve component, optimizing the operating angle, and improving assembly efficiency.
