[0062] Through the coordination between the left limiting valve 51, the right limiting valve 52, the pressure gauge 2 and the pressure regulating outlet connector 34, not only can the actual air pressure on the upper side of the pressure regulating valve 3 be displayed in real time, but also the air pressure in the passage can be adjusted while limiting the gas flow rate into the pneumatic chuck.

[0063] The above-mentioned left flow limiting valve 51 and right flow limiting valve 52 both include a flow limiting valve body (not marked in the figure) and a flow limiting knob (not marked in the figure) connected to the flow limiting valve body. The flow limiting knob is used to adjust the gas flow rate in the flow limiting valve body. The flow limiting knob is located in the flow limiting valve body and on the outside of the shell.

[0068] Specifically, combined Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the left control air inlet connector 411, the right control air inlet connector 412, the left control air outlet connector 421 and the right control air outlet connector 422 are respectively air pipe elbow connectors, and their model may be KXL04-M5, and the number of the left control air outlet connector 421 and the right control air outlet connector 422 are respectively two.

[0069] The control switch group 4 includes a left control switch 43 and a right control switch 44 which are arranged opposite to each other along the length direction of the housing 1. The left control switch 43 and the right control switch 44 can be toggle switches, respectively, and the model is TAC 4V. The toggle switch has a control valve body 430 and a toggle rod 431 connected to the control valve body 430. The control valve body 430 is a one-in-two-out structure, that is, the control valve bodies 430 in the left control switch 43 and the right control switch 44 have a control inlet and two control outlets, respectively, and the control inlet and the two control outlets are respectively located on two opposite sides of the control valve body 430 in the left control switch 43 along the length direction of the housing 1, such as a control inlet can be located on the upper side of the control valve body 430 in the left control switch 43 along the length direction of the housing 1, and the two control outlets can be located on the lower side of the control valve body 430 in the left control switch 43 along the length direction of the housing 1; One control inlet and two control outlets are respectively located on two opposite sides of the control valve body 430 in the right control switch 44 along the length direction of the shell 1. For example, one control inlet can be located on the upper side of the control valve body 430 in the right control switch 44 along the length direction of the shell 1, and the two control outlets can be located on the lower side of the control valve body 430 in the right control switch 44 along the length direction of the shell 1. Specifically, in this embodiment, the left control switch 43 and the right control switch 44 have two air outlets, and the two air outlets can only be opened on one side. The opening and clamping of the left control switch 43 and the right control switch 44 are realized by toggling the levers 431 of the left control switch 43 and the right control switch 44.

Since the two air outlets in the left control switch 43 and the right control switch 44 can only be opened on one side, when the control outlet of one left control switch 43 is opened, the control outlet of the other left control switch 43 is disconnected, and when the control outlet of one right control switch 44 is opened, the control outlet of the other right control switch 44 is disconnected.

[0071] The left flow limiting valve 51 and the right flow limiting valve 52 are respectively connected to the flow limiting lower joints on the other side of the shell 1 in the height direction. For example, the two flow limiting lower joints are respectively located on the lower side of the left flow limiting valve 51 and the right flow limiting valve 52 in the height direction of the shell 1, that is, the flow limiting upper joint 53 and the flow limiting lower joint in this embodiment are respectively located on the relatively upper and lower sides of the left flow limiting valve 51 and the right flow limiting valve 52, and the flow limiting upper joint 53 and the flow limiting lower joint can be connected.

[0072] The left control air inlet connector 411 and the right control air inlet connector 412 are respectively connected to the lower flow limiting connector in the left flow limiting valve 51 and the lower flow limiting connector in the right flow limiting valve 52, and the left control air outlet connector 421 and the right control air outlet connector 422 are respectively connected to the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8. The lever 431 of the left control switch 43 is toggled to deliver the limited gas through the control outlet of a control switch of the left control switch 43 and the first chuck air inlet nozzle group 7 to the chuck air inlet nozzle B in a pneumatic chuck. Then, the lever 431 of the right control switch 44 is toggled to deliver the limited gas through the control outlet of a control switch of the right control switch 44. The control outlet of the control switch and the second chuck air inlet nozzle group 8 deliver gas to the chuck air inlet nozzle D in the other pneumatic chuck, thereby realizing the clamping action of a pair of pneumatic chucks; the lever 431 of the left control switch 43 is pushed to the other side, and the gas after flow limitation is delivered to the chuck air inlet nozzle A in the pneumatic chuck through the control outlet of a control switch of the left control switch 43 and the first chuck air inlet nozzle group 7; then, the lever 431 of the right control switch 44 is pushed to the other direction, and the gas after flow limitation is delivered to the chuck air inlet nozzle C in the pneumatic chuck through the control outlet of a control switch of the right control switch 44 and the second chuck air inlet nozzle group 8, thereby realizing the opening of the pneumatic chuck.

[0073] By adopting the above scheme, the left control air inlet connector 411, the flow limiting lower connector and the right control air inlet connector 412 cooperate with each other, which is conducive to connecting the flow limiting valve, the left control switch 43, the right control switch 44, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle together, which not only simplifies the number of air path control switches, but also reduces the complexity and confusion of operation, and is also convenient for disassembly and assembly.

At the same time, this connection method is also conducive to regular inspection and maintenance of the pressure regulating valve 3 and the control switch group 4 to ensure their long-term stable operation.

[0099] In an alternative embodiment, referring to Fig.15 and Fig.16 As shown, Fig.15 This is a schematic structural diagram of a housing provided by the present invention in another direction; Fig.16 1 is a schematic diagram of the structure of a housing provided by the present invention in another direction; a rear opening 121 matching the flow limiting valve group 5, the main air inlet nozzle 6, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 is opened on the rear side plate 12, and the rear opening 121 penetrates the rear side plate 12 in the direction from the rear side plate 12 to the front side plate 11;

[0100] The flow limiting valve group 5 , the main air inlet nozzle 6 , the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 are respectively embedded in the rear opening 121 through the rear plate nut 122 .

[0101] The rear opening 121 includes a flow limiting hole 121a, a total air inlet hole 121b, a first clamp air inlet nozzle hole 121c, and a second clamp air inlet nozzle hole 121d.

[0102] The total air inlet nozzle 6 is embedded in the total air inlet hole 121b through the total air inlet nut 122b. When the limiting valve group 5 includes a left limiting valve 51 and a right limiting valve 52, the first chuck air inlet nozzle group 7 includes an air inlet nozzle 71 on the first chuck and an air inlet nozzle 72 under the first chuck, and the second chuck air inlet nozzle group 8 includes an air inlet nozzle 81 on the second chuck and an air inlet nozzle 82 under the second chuck, the left limiting valve 51 and the right limiting valve 52 are respectively embedded in the limiting hole 121a through the limiting nut 122a, the air inlet nozzle 71 on the first chuck and the air inlet nozzle 72 under the first chuck are embedded in the first chuck air inlet nozzle hole 121c through the first chuck air inlet nozzle nut 122c, and the air inlet nozzle 81 on the second chuck and the air inlet nozzle 82 under the second chuck are embedded in the second chuck air inlet nozzle hole 121d through the second chuck air inlet nozzle nut 122d.

[0103] The above scheme is adopted, which is not only convenient for integrating the flow limiting valve group 5, the total air inlet nozzle 6, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 into the rear side plate 12 of the housing 1, but also the installation method is relatively simple and quick, and does not require complicated connection processes or additional installation tools, thereby reducing the installation cost and time. When the flow limiting valve group 5, the total air inlet nozzle 6, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 need to be maintained or replaced, they can be easily disassembled and reinstalled, reducing the maintenance difficulty and cost. At the same time, this connection method is also conducive to regular inspection and maintenance of the flow limiting valve group 5, the total air inlet nozzle 6, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 to ensure their long-term stable operation.

[0104] In an optional embodiment, the pressure gauge 2, the pressure regulating valve 3 and the control switch group 4 are sequentially embedded in the front side plate 11 along the height direction of the shell 1; the flow limiting valve group 5 is located above the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8, and the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8 are arranged around the total air inlet nozzle 6.

[0105] Continue to refer to Figure 3 , Figure 4 and Figure 5As shown, in the above scheme, when the flow limiting valve group 5 includes the left flow limiting valve 51 and the right flow limiting valve 52, since the left flow limiting valve 51 and the right flow limiting valve 52 are located above the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8, so that the pressure regulating air inlet nozzle 33 and the total air inlet nozzle 6, the pressure regulating air outlet joint 34 and the pressure gauge 2, the pressure regulating air outlet joint 34 and the flow limiting valve group 5, the control air inlet joint group 41 and the flow limiting valve group 5, the first chuck air inlet nozzle group 7 and the control air outlet joint group 42, and the second chuck air inlet nozzle group 8 and the control air outlet joint group 42 are connected through air paths respectively, the above scheme is adopted. The scheme is beneficial to the layout between the pressure gauge 2, the pressure regulating valve 3, the flow limiting valve group 5, the control switch group 4, the main air inlet nozzle 6, the first chuck air inlet nozzle group 7 and the second chuck air inlet nozzle group 8, and subsequently avoids the air pipes between the pressure regulating air inlet nozzle 33 and the main air inlet nozzle 6, between the pressure regulating air outlet joint 34 and the pressure gauge 2, between the pressure regulating air outlet joint 34 and the flow limiting valve group 5, between the control air inlet joint group 41 and the flow limiting valve group 5, between the first chuck air inlet nozzle group 7 and the control air outlet joint group 42, and between the second chuck air inlet nozzle group 8 and the control air outlet joint group 42 being too long, which saves the length of the air pipe and reduces the cost.

[0106] The inventors discovered that the fully enclosed structure of the shell 1 will cause a relatively high air pressure inside the shell 1, resulting in the risk of damage to the pressure gauge 2, the pressure regulating valve 3, the control switch group 4, the flow limiting valve group 5, the main air inlet nozzle 6, the first chuck air inlet nozzle group 7 and / or the second chuck air inlet nozzle group 8.
