[0068] Specifically, combined Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 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 trachea elbow connectors, and their model can be KXL04-M5. 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 that 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, whose 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-inlet and two-outlet structure, that is, the control valve bodies 430 in the left control switch 43 and the right control switch 44 respectively have a control inlet and two control outlets, and the one 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. For example, one 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. By toggling the toggle lever 431 of the left control switch 43 and the right control switch 44, the opening and clamping of the left control switch 43 and the right control switch 44 are realized.

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 surface along the height direction of the shell 1. For example, the two flow limiting lower joints are respectively located on the lower side surfaces of the left flow limiting valve 51 and the right flow limiting valve 52 along 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 side surfaces 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 flow limiting lower connector in the left flow limiting valve 51 and the flow limiting lower 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 one side, and the gas after flow limiting is delivered to the chuck air inlet nozzle B in a 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 toggled to one side, and the gas after flow limiting is delivered to the chuck air inlet nozzle B in a pneumatic chuck 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 toggled 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 toggled 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.

The gas entering the main air inlet nozzle 6 passes through the pressure regulating valve 3, the right flow limiting valve 52, the right control switch 44, and the air inlet nozzle 81 on the second chuck to inflate the chuck air inlet nozzle D. After inflating through the chuck air inlet nozzle D, the air cavity in the other pneumatic chuck is pushed downward, so that the two clamping blocks 9 in the other pneumatic chuck are closed. Open the left control switch 43 and the right control switch 44 in turn, and the two clamping blocks 9 in a pair of pneumatic chucks are closed to facilitate clamping the opposite sides of the object; the inflation speed of the chuck air inlet nozzles B and D controls the opening and clamping speed, and the inflation pressure will affect the clamping force of the two chucks.

[0086] The lever 431 in the left control switch 43 is moved to the other side, and the gas entering the main air inlet nozzle 6 passes through the pressure regulating valve 3, the left flow limiting valve 51, the left control switch 43 and the first chuck lower air inlet nozzle 72 to inflate the chuck air inlet nozzle A.

[0090] The above-mentioned first chuck air inlet nozzle group 7 and second chuck air inlet nozzle group 8 are arranged relatively to each other along the height direction of the shell 1, such as the first chuck air inlet nozzle group 7 is located on the upper side of the shell 1, and the second chuck air inlet nozzle group 8 is located on the lower side of the shell 1, or the first chuck air inlet nozzle group 7 is located on the upper side of the shell 1, and the second chuck air inlet nozzle group 8 is located on the lower side of the shell 1.

[0091] The first chuck left air inlet nozzle 73 and the first chuck right air inlet nozzle 74 are respectively located at the left and right positions above the shell 1 , and the second chuck left air inlet nozzle 83 and the second chuck right air inlet nozzle 84 are respectively located at the left and right positions below the shell 1 .

[0092] The above-mentioned first chuck left air inlet nozzle 73 and the first chuck right air inlet nozzle 74 are respectively connected to the two left control air outlet connectors 421, and the second chuck left air inlet nozzle 83 and the second chuck right air inlet nozzle 84 are respectively connected to the two right control air outlet connectors 422, such as the first chuck left air inlet nozzle 73 and one left control air outlet connector 421, the first chuck right air inlet nozzle 74 and another left control air outlet connector 421, the second chuck left air inlet nozzle 83 and one right control air outlet connector 422, and the second chuck right air inlet nozzle 84 and another right control air outlet connector 422 are connected through air pipes.

The air pipes can be made of plastic material, so that they can be plugged in 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. Not only is the overall structure simple, but it is also easy to operate and has a low price.

[0096] In an alternative embodiment, referring to Figure 14 As shown, Figure 14 It is a structural schematic diagram of one direction of a shell provided by the present invention; a front opening 111 matching the pressure gauge 2, the pressure regulating valve 3 and the control switch group 4 is opened on the front side plate 11, and the front opening 111 passes through the front side plate 11 in the direction pointing to the rear side plate 12; the pressure regulating valve 3 and the control switch group 4 are respectively embedded in the front opening 111 through front plate nuts (not marked in the figure).

[0097] Specifically, the front opening 111 includes a gauge hole 111a, a pressure regulating hole 111b and a switch hole 111c. The gauge hole 111a, the pressure regulating hole 111b and the switch hole 111c respectively penetrate the front side plate 11 in the direction from the front side plate 11 to the rear side plate 12. The pressure gauge 2 is embedded in the gauge hole 111a. The front plate nut includes a pressure regulating valve nut (not marked in the figure) and a switch nut (not marked in the figure).

When the control switch group 4 includes a left control switch 43 and a right control switch 44, the left control switch 43 and the right control switch 44 are respectively embedded in the two switch holes 111c through the switch nuts.

[0098] The above solution not only facilitates the integration of the pressure gauge 2, pressure regulating valve 3, and control switch group 4 into the housing 1, but also provides a relatively simple and quick installation method, requiring no complex connection processes or additional installation tools, thereby reducing installation costs and time. When the pressure regulating valve 3 and control switch group 4 need maintenance or replacement, they can be easily removed and reinstalled, reducing maintenance difficulty and costs. Furthermore, this connection method also facilitates regular inspection and maintenance of the pressure regulating valve 3 and control switch group 4, ensuring their long-term stable operation.

[0099] In an alternative embodiment, referring to Figure 15 and Figure 16 As shown, Figure 15 This is a schematic structural diagram of a housing provided by the present invention in another direction; Figure 16 2 is a schematic structural diagram of a housing provided by the present invention from another direction; a rear opening 121 is provided on the rear side plate 12 to match 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. The rear opening 121 penetrates the rear side plate 12 in a direction from the rear side plate 12 to the front side plate 11;

[0100] The flow limiting valve assembly 5 , the main air inlet nozzle 6 , the first chuck air inlet nozzle assembly 7 and the second chuck air inlet nozzle assembly 8 are respectively engaged with the rear opening 121 through rear plate nuts 122 .

[0101] The rear opening 121 includes a flow-limiting hole 121a, a total air inlet hole 121b, a first chuck air inlet nozzle hole 121c, and a second chuck air inlet nozzle hole 121d. The number of flow-limiting holes 121a can be two, and the number of first chuck air inlet nozzle holes 121c and second chuck air inlet nozzle holes 121d can be two, respectively. The rear plate nut 122 includes a flow-limiting nut 122a, a total air inlet nut 122b, a first chuck air inlet nozzle nut 122c, and a second chuck air inlet nozzle nut 122d. The number of first chuck air inlet nozzle nuts 122c and second chuck air inlet nozzle nuts 122d can be two.

[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 flow limiting valve group 5 includes a left flow limiting valve 51 and a right flow limiting valve 52, the first chuck air inlet nozzle group 7 includes a first chuck upper air inlet nozzle 71 and a first chuck lower air inlet nozzle 72, and the second chuck air inlet nozzle group 8 includes a second chuck upper air inlet nozzle 81 and a second chuck lower air inlet nozzle 82, the left flow limiting valve 51 and the right flow limiting valve 52 are respectively embedded in the flow limiting hole 121a through the flow limiting nut 122a, the first chuck upper air inlet nozzle 71 and the first chuck lower air inlet nozzle 72 are embedded in the first chuck air inlet nozzle hole 121c through the first chuck air inlet nozzle nut 122c, and the second chuck upper air inlet nozzle 81 and the second chuck lower air inlet nozzle 82 are embedded in the second chuck air inlet nozzle hole 121d through the second chuck air inlet nozzle nut 122d.

[0103] The above solution is not only convenient for integrating 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 into the rear side plate 12 of the housing 1, but also the installation method is relatively simple and quick, without the need for complex connection processes or additional installation tools, thereby reducing installation costs and time. When 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 need to be maintained or replaced, they can be easily disassembled and reinstalled, reducing 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 main 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 embedded in the front side plate 11 in sequence 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 main 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 main 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, saving the air pipe length while reducing costs.

[0106] The inventors found that the fully enclosed structure of the shell 1 will cause the air pressure inside the shell 1 to be relatively high, 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.

[0107] Based on the above problems, in this embodiment, the shell 1 also includes a bottom plate 16 connected to the front side plate 11 and the rear side plate 12. A bottom plate hole 161 is opened on the bottom plate 16, and the bottom plate hole 161 passes through the bottom plate 16 along the height direction of the shell 1. The bottom plate 16 can be rectangular, such as a rectangle, and a bottom plate hole 161 is opened on the bottom plate 16. The number of bottom plate holes 161 can be at least one. When the number of bottom plate holes 161 is two or more, the more than two bottom plate holes 161 are arranged along the width direction of the shell 1. The shape of the bottom plate hole 161 can be elliptical, long strip, rectangular, circular or fan-shaped.

[0108] By adopting the above solution, the air pressure balance inside and outside the shell 1 can be achieved, and 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 can be greatly reduced.

[0109] It can be seen from the above embodiments that the pneumatic chuck controller with adjustable air pressure and flow rate provided by the present invention achieves at least the following beneficial effects:

[0110] 14. The air flow control system of claim 13, wherein the air flow control valve is mounted on a front flank of the air intake manifold and is located adjacent the air intake manifold. The air flow control valve is mounted on a front flank of the air intake manifold and is located adjacent the air intake manifold. and a pressure regulating valve body and an adjusting knob connected to the pressure regulating valve body, the pressure regulating valve body being respectively connected with a pressure regulating inlet nozzle and a pressure regulating outlet joint on two opposite sides along the height direction of the shell, the pressure regulating inlet nozzle is connected with the main air inlet nozzle, and the pressure regulating outlet joint is respectively connected with a pressure gauge and a flow limiting valve group; the control switch group is respectively connected with a control inlet joint group and a control outlet joint group on two opposite sides along the height direction of the shell, the control inlet joint group is connected with the flow limiting valve group, and the first chuck inlet nozzle group and the second chuck inlet nozzle group are respectively connected with the control outlet joint group. The above scheme is adopted to integrate the pressure gauge, the pressure regulating valve and the control switch group into the front side panel, and the flow limiting valve group, the main air inlet nozzle, the first chuck inlet nozzle group and the second chuck inlet nozzle group into the rear side panel, that is, the shell has high integration and complete functions, and can accurately control the clamping and opening rate and clamping force of the two clamping blocks in the pneumatic chuck through the flow limiting valve group and the pressure regulating valve. Compared with existing technologies, this pneumatic chuck controller has more comprehensive functions. Specifically, it improves the convenience of operation and the accuracy of control through a visual pressure gauge and pressure regulating valve.
