Description

Technical Field

[0001] The present application relates to the technical field of pneumatic valve production equipment, and in particular to a press-fitting device for a magnetic isolation tube sleeve of a pneumatic valve. Background Art

[0002] With the continuous development of the social economy and the increasing improvement of the scientific and technological level, the automobile manufacturing industry in our country is also booming. As a valve that uses compressed air to drive the movement of multiple sets of combined pneumatic pistons in the actuator, the pneumatic valve can control the flow of brake fluid in the automobile braking system and flexibly adjust the flow rate and direction of the coolant in the automobile cooling system, so it plays an important role. When producing a pneumatic valve, it is necessary to press-fit a magnetic isolation tube sleeve of the pneumatic valve onto the valve body.

[0003] There is a press-fitting device for a magnetic isolation tube sleeve of a pneumatic valve in the prior art. It includes a machine body, on which a press-fitting table and a press-fitting mechanism are provided. The press-fitting mechanism includes a hydraulic cylinder and a press-fitting seat. The press-fitting seat is located above the press-fitting table. The piston rod of the hydraulic cylinder is vertically downward and fixedly connected to the press-fitting seat. An opening is formed at the top of the press-fitting table for the valve body of the pneumatic valve to be embedded. In use, the bottom of the valve body is placed in the opening on the press-fitting table, then the magnetic isolation tube sleeve of the pneumatic valve is sleeved on the valve body, and then the hydraulic cylinder is controlled to drive the press-fitting seat to move downward to press-fit the magnetic isolation tube sleeve of the pneumatic valve onto the valve body, so that the magnetic isolation tube sleeve of the pneumatic valve and the valve body are in interference fit.

[0004] In view of the above related technologies, since in the prior art, after each press-fitting of the magnetic isolation tube sleeve of the pneumatic valve is completed, relevant personnel are required to manually take out the press-fitted valve body from the opening on the press-fitting table, then place the bottom of the valve body in the opening on the press-fitting table, and sleeve the magnetic isolation tube sleeve of the pneumatic valve on the valve body before the next press-fitting of the magnetic isolation tube sleeve of the pneumatic valve can be carried out, which greatly reduces the press-fitting efficiency of the magnetic isolation tube sleeve of the pneumatic valve and thus needs to be improved. Summary of the Invention

[0005] In order to improve the press-fitting efficiency of the magnetic isolation tube sleeve of the pneumatic valve, the present application provides a press-fitting device for a magnetic isolation tube sleeve of a pneumatic valve.

[0006] The press-fitting device for a magnetic isolation tube sleeve of a pneumatic valve provided by the present application adopts the following technical solutions: A press-fitting device for a magnetic isolation tube sleeve of a pneumatic valve includes a device body, on which a press-fitting mechanism is provided. It also includes a feeding mechanism and a conveying mechanism. The conveying mechanism includes a conveying frame and a conveying component. The number of the conveying frames is set to be several. Each conveying frame is slidably connected to the device body. The sliding paths of the several conveying frames are the same and are all closed-loop. The sliding path of each conveying frame passes directly below the press-fitting mechanism. The conveying component is used to drive each conveying frame to slide along its own sliding path. The feeding mechanism is used to place the valve body and the magnetic isolation tube sleeve of the pneumatic valve on the conveying frame.

[0007] By adopting the above technical solution, compared with the prior art, in the prior art, relevant personnel need to remove the valve body after the press-fitting from the press-fitting table each time, then place the valve body to be press-fitted on the press-fitting table, and need to sleeved the magnetic isolation tube sleeve of the air valve on the top of the valve body before the press-fitting mechanism can press-fit the valve body and the magnetic isolation tube sleeve of the air valve, which reduces the press-fitting efficiency. In this application, by setting up the feeding mechanism and the conveying mechanism, the feeding mechanism can place the valve body and the magnetic isolation tube sleeve of the air valve on the conveying rack, so that when the conveying rack is transported to directly below the press-fitting mechanism, the press-fitting mechanism can press-fit the valve body and the magnetic isolation tube sleeve on the conveying rack, effectively replacing the operation of relevant personnel manually taking and replacing the valve body, realizing the automatic press-fitting of the valve body, and effectively improving the press-fitting efficiency of the valve body and the magnetic isolation tube sleeve in this application.

[0008] Preferably, a positioning mechanism is provided on the device body. The positioning mechanism includes a driving component and a plurality of clamping frames. The plurality of clamping frames are respectively located on the periphery of a specific conveying rack. Each clamping frame is slidably connected to the device body, and the specific conveying rack is located on the sliding path of each clamping frame. The driving component is used to drive each clamping frame to slide; the specific conveying rack is the conveying rack located directly below the press-fitting mechanism.

[0009] By adopting the above technical solution, the setting of the positioning mechanism enables the clamping frame to clamp the conveying rack located directly below the press-fitting mechanism under the drive of the driving component, thereby realizing the positioning and fixing of the conveying rack located directly below the press-fitting mechanism, and effectively ensuring the press-fitting effect between the valve body and the magnetic isolation tube sleeve of the air valve, and ensuring the quality and stability of the press-fitting.

[0010] Preferably, a supporting mechanism is further provided on the device body. The supporting mechanism includes a supporting frame and a linkage component. The supporting frame is located directly below the specific conveying rack and is slidably connected to the device body, and the specific conveying rack is located on the sliding path of the supporting frame. The linkage component is used to drive the supporting frame to slide.

[0011] By adopting the above technical solution, the setting of the supporting mechanism enables the linkage component to drive the supporting frame to slide, so that the top of the supporting frame can abut against the bottom of the conveying rack located directly below the press-fitting mechanism, thereby supporting the conveying rack, and effectively reducing the probability that the conveying rack deflects downward due to excessive pressure during the press-fitting by the press-fitting mechanism, and effectively ensuring the press-fitting effect and the quality after press-fitting.

[0012] Preferably, the linkage assembly includes a linkage member, a gear-rack group, and a redirecting frame. The redirecting frame is slidably connected to the device body, and the sliding direction is parallel to the sliding direction of the support frame. The redirecting frame drives the support frame to slide through the gear-rack group, so that the sliding directions of the redirecting frame and the support frame are opposite. One of the clamping frames drives the redirecting frame to slide through the linkage member.

[0013] By adopting the above technical solution, the setting of the linkage assembly enables the clamping frame to drive the redirecting frame to slide through the linkage member during the process of clamping the conveying frame directly below the press-fitting mechanism. Furthermore, the redirecting frame drives the support frame to slide upward through the gear-rack group, thereby realizing the drive of the support frame and simultaneously realizing the linkage between the clamping frame and the support frame. This effectively replaces the additional active devices required to drive the support frame and facilitates the operation of relevant personnel.

[0014] Preferably, the linkage member includes a linkage frame. The linkage frame is rotatably connected to the clamping frame and rotatably connected to the redirecting frame. Moreover, the rotational connection between the linkage frame and the clamping frame is different from the rotational connection between itself and the redirecting frame.

[0015] By adopting the above technical solution, the setting of the linkage frame enables the clamping frame to drive the linkage frame to displace during the sliding process, and then the linkage frame drives the redirecting frame to slide, effectively realizing the linkage between the clamping frame and the redirecting frame and realizing the drive of the redirecting frame to slide. Furthermore, the active devices required to drive the redirecting frame to slide are saved, and the operation of relevant personnel is facilitated.

[0016] Preferably, the driving assembly includes a plurality of active frames, a plurality of driven frames, and a plurality of driving members. The active frames, the driven frames, and the driving members all correspond to the clamping frame. One end of the active frame is rotatably connected to the device body, and the other end is rotatably connected to the driven frame. The other end of the driven frame is rotatably connected to the corresponding clamping frame. Each driving member is used to drive the corresponding active frame to rotate.

[0017] By adopting the above technical solution, the setting of the driving assembly enables the driving member to drive the active frame to rotate when it is necessary to drive the clamping to slide. Thus, the active frame can drive the corresponding driven frame to displace, and then the end of the driven frame drives the corresponding clamping frame to slide, realizing the sliding of the clamping frame. The existence of the active frame and the driven frame can effectively support the clamping frame, thereby reducing the probability of the clamping frame bending or being misaligned.

[0018] Preferably, a placement mechanism and a welding mechanism are further provided on one side of the device body along the moving direction of the conveying rack. The welding mechanism includes a rotating table, a rotating member, and a welding member. The placement mechanism is used to transport the valve body after press-fitting on the conveying rack to the rotating table. The rotating table is located directly below the welding member and is used to place the press-fitted valve body. The rotating member is used to drive the rotating table to rotate. The welding member is used to weld the intersection between the valve body on the rotating table and the magnetic shielding tube sleeve of the air valve.

[0019] By adopting the above technical solution, the arrangement of the placement mechanism and the welding mechanism enables the placement mechanism to transport the conveyed and press-fitted valve body to the rotating table, so that the rotating member can drive the rotating table to rotate, enabling the welding mechanism to weld the intersection between the valve body and the magnetic shielding tube sleeve of the air valve, thus effectively replacing the manual welding method and improving the welding efficiency.

[0020] Preferably, an output mechanism and an output conveyor belt are further provided on one side of the welding mechanism. The output mechanism is used to transport the welded valve body to the output conveyor belt. The output conveyor belt is used to transport the valve body to the side away from the welding mechanism.

[0021] By adopting the above technical solution, the arrangement of the output mechanism and the output conveyor belt enables the output mechanism to move the welded valve body out of the rotating table and place it on the output conveyor belt after the welding mechanism has welded the intersection between the valve body and the magnetic shielding tube sleeve of the air valve, enabling the output conveyor belt to output the welded valve body, effectively replacing the manual output method, and thus improving the output efficiency.

[0022] Preferably, the conveying assembly includes a conveying member, a closed-loop chain, and a plurality of driving sprockets. Each driving sprocket is rotatably connected to the device body. The closed-loop chain is sleeved on each driving sprocket and is connected to each conveying rack. The closed-loop chain passes under the press-fitting mechanism. The conveying member is used to drive one of the driving sprockets to rotate.

[0023] By adopting the above technical solution, the arrangement of the conveying assembly enables the conveying member to drive one of the driving sprockets to rotate, causing the driving sprocket to drive the closed-loop chain to move, thereby enabling the closed-loop chain to drive the conveying rack and realizing the closed-loop driving of the conveying rack. At the same time, the conveying rack can automatically return to the initial position during the movement for recycling.

[0024] Preferably, a plurality of rollers are provided at the bottom of the conveying rack. Each roller is rotatably connected to the corresponding conveying rack. Each roller is embedded in the device body, and the side wall of each roller abuts against the inner side wall of the device body.

[0025] By adopting the above technical solution, the setting of the roller enables the roller to abut against the inner side wall of the machine body, thereby changing the sliding friction between the conveying rack and the machine body into the rolling friction between the roller and the machine body, effectively ensuring the smooth movement of the conveying rack, and at the same time ensuring the movement stability of the conveying rack, and further ensuring the stability of the valve body sleeved with the air valve magnetic isolation tube sleeve during movement.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the feeding mechanism and the transportation mechanism enables the feeding mechanism to place the valve body and the air valve magnetic isolation tube sleeve on the conveying rack, so that when the conveying rack is transported to directly below the press-fitting mechanism, the press-fitting mechanism can press-fit the valve body and the air valve magnetic isolation tube sleeve on the conveying rack, effectively replacing the operation of manually taking and replacing the valve body by relevant personnel, realizing the automatic press-fitting of the valve body, and effectively improving the press-fitting efficiency of the valve body and the air valve magnetic isolation tube sleeve in the present application; 2. The setting of the positioning mechanism enables the clamping rack to clamp the conveying rack located directly below the press-fitting mechanism under the drive of the driving component, thereby realizing the positioning and fixing of the conveying rack located directly below the press-fitting mechanism, and further effectively ensuring the press-fitting effect between the valve body and the air valve magnetic isolation tube sleeve, and ensuring the quality and stability of the press-fitting; 3. The setting of the placing mechanism and the welding mechanism enables the placing mechanism to transport the conveyed and press-fitted valve body to the rotating table, so that the rotating member can drive the rotating table to rotate, enabling the welding mechanism to weld the intersection between the valve body and the air valve magnetic isolation tube sleeve, thereby effectively replacing the manual welding method and improving the welding efficiency.

[0053] Refer to Figure 1 and Figure 2 , an output mechanism 9 and an output conveyor belt 10 are further arranged on one side of the frame 81. In the embodiment of the present application, the output mechanism 9 is set as an industrial robot, and this industrial robot is located on one side of the frame 81, and is used to clamp the valve body after the welding is completed, and then place the valve body on the output conveyor belt 10.

[0054] The implementation principle of a valve magnetic isolation tube sleeve press-fitting device in the embodiment of the present application is as follows: When in use, one feeding robot 22 is used to place the valve body conveyed by the corresponding feeding conveyor belt 21 into the opening of the corresponding conveying frame 31, and the other feeding robot 22 is used to clamp the valve magnetic isolation tube sleeve and sleeved on the top of the valve body on the conveying frame 31. After that, the conveying member 321 drives the driving transmission sprocket 323 to rotate, so that the closed-loop chain 322 transports the conveying frame 31 to directly below the press-fitting seat 42.

[0055] Then, the positioning mechanism 5 positions the conveying frame 31, and the supporting mechanism 6 supports the conveying frame 31. After that, the hydraulic cylinder 41 drives the press-fitting seat 42 to move downward to press-fit the valve magnetic isolation tube sleeve on the top of the valve body. After that, the closed-loop chain 322 continues to convey. When the conveying frame 31 is transported to the designated position, the placing mechanism 7 transports the valve body on the conveying frame 31 to the rotating table 82, so that the welding robot welds the intersection between the valve body and the valve magnetic isolation tube sleeve. After that, the output mechanism 9 transports the valve body after the welding is completed onto the output conveyor belt 10, so that the output conveyor belt 10 transports the valve body after the welding is completed to the next process.

[0056] The above are all the preferred embodiments of the present application.
