[0025] In order to make the purpose, technical scheme and advantage of the utility model more clear, the embodiment of the utility model will be described in further detail below in combination with the drawings.
[0026] Please refer to Figs. 1-3 , and it is the structural schematic diagram of the embodiment of the processing tool Z direction gas detection device of the utility model, please refer to Figs. 1-3 , and the processing tool Z direction gas detection device is introduced in detail.
[0027] The processing tool Z direction gas detection device, including support block 100, mounting seat 101, fixed needle 102 pressure detection device 103 and floating head 104;
[0028] The support block 100 is used to bear workpiece, the mounting seat 101 is installed below the support block 100 through fixed needle 102, the perpendicular air passage 108 is fixedly arranged in the mounting seat 101, the upper end of the air passage 108 extends to the support block 100, and the upper end of the air passage 108 is connected with blowing channel 105, and the other end of the air passage 108 is communicated with exhaust pipe 106;
[0029] The air pressure detection device 103 is connected with the air passage 108 on the mounting base 101 through the air pipe 111.
[0030] The fixed needle 102 is provided with a groove in the shape of a Chinese character at one end and is designed with a thread 109 at the other end and is screwed with a matched nut 110, the mounting base 101 is provided with a mounting hole 107 for mounting the fixed needle 102, the mounting hole 107 is staggered with the air passage 108 to avoid the influence of the fixed needle 102 on the use of the air passage 108;
[0031] The mounting base 101 is fixedly provided with a gas charging pipe 112 connected with the air passage 108 inside, the other end of the gas charging pipe 112 is located outside the mounting base 101 and is connected with a gas charging device, which is not shown in the figure and belongs to the existing common device, such as a gas charging pump, a gas charging machine, etc;
[0032] The inner walls of the air passage 108, the exhaust pipe 106, the air pipe 111, the air blowing passage 105 and the gas charging pipe 112 are smooth, and the air passage 108, the exhaust pipe 106, the air pipe 111, the gas charging pipe 112 and the air blowing passage 105 are fixedly connected, which can be connected through flanges, and sealing washers are arranged at the connection positions;
[0033] The floating head 104 is located above the supporting block 100, the floating head 104 is made of elastic material, and the bottom of the floating head 104 blocks the air blowing hole at the top of the air blowing passage 105; in actual application, according to the shape and weight of different workpieces, the shapes of the supporting block 100 and the floating head 104 can be designed as a plane, a groove surface and other forms. For example, for workpieces with a relatively flat bottom, a plane floating head 104 is used; for workpieces with protrusions or depressions on the bottom, a groove surface or a convex surface floating head 104 is designed to match them. Such design can effectively improve the load stability of the floating head 104 to the workpiece, reduce the displacement of the workpiece during air detection, improve the accuracy of air detection, and thus improve the workpiece qualification rate;
[0034] The other end of the exhaust pipe 106 is communicated with the outside of the mounting base 101, and the inner diameter of the air passage 108 is at least three times the inner diameter of the exhaust pipe 106, so that when the gas charging device is started to rush gas into the inside through the gas charging pipe 112, due to the fact that the inner diameter of the air passage 108 is at least three times the inner diameter of the exhaust pipe 106, the exhaust amount of the exhaust pipe 106 is small, and a large amount of gas will be blown to the floating head 104 through the air blowing passage 105;
[0035] In the specific use process, when the workpiece is placed on the floating head 104, the air blowing passage 105 is arranged below the floating head 104, if the workpiece is placed in place, the weight of the workpiece will cause the floating head 104 to bear a certain pressure;
[0036] At this time, the inflation device is started to inject gas into the interior through the inflation pipe 112, and since the inner diameter of the air passage 108 is at least three times the inner diameter of the exhaust pipe 106, the exhaust pipe 106 has a small exhaust capacity, and a large amount of gas will be blown to the floating head 104 through the blowing passage 105, and since the floating head 104 has the weight of the workpiece, the gas cannot easily blow up the floating head 104, and the air pressure in the gas detection device will increase, and the air pressure detection device 103 can detect a larger air pressure, indicating that the workpiece is placed in place;
[0037] On the contrary, if the workpiece is not placed in place, the floating head 104 has no weight of the workpiece, at this time the gas will gradually leak from the exhaust pipe 106, and the air pressure detected by the air pressure detection device 103 is relatively small, indicating that the workpiece is not placed in place.
[0038] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the utility model can be combined in any way, and the combinations are not exhaustively described in the specification only for the purpose of saving space and resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
