In order to achieve the above object, the utility model provides a gear pastes flat detection device, include:
the clamping device comprises a chuck, clamping steps are arranged at the end parts of the inner sides of clamping jaws of the chuck, an air hole is formed in each clamping jaw, and the tail end of each air hole is positioned on the upper surface of the step of each clamping step;
the ventilation assembly comprises a main ventilation pipe connected with a gas source, a pressure gauge and an electromagnetic valve are connected to the main ventilation pipe, branch ventilation pipes corresponding to the chuck jaws in number are further connected to the main ventilation pipe, and the branch ventilation pipes are fixedly connected to the air holes of the chuck jaws.
Further, the chuck adopts a three-jaw chuck, and the air holes enter from the outer side ends of the jaws.
Further, the air hole comprises a horizontal air hole part and a vertical air hole part.
Further, the jack catch includes fixed part and movable part, movable part detachable connects on the fixed part.
Furthermore, the pressure gauge adopts a YSD-Y60-2 type digital display pressure gauge.
The beneficial effects of utility model are that:
firstly, the detection device is simple in structure, after the gear is clamped, whether the gear is flat or not can be rapidly detected, the detection efficiency is high, and the rejection rate is effectively reduced;
secondly, when the gear is not flatly attached to the chuck, the pressure gauge can quickly display the gear, so that whether the gear is flatly attached or not is judged quickly;
thirdly, the main vent pipe is connected with the three vent pipes, if one vent pipe is not blocked by the gear, the pressure gauge of the main vent pipe can be displayed, and therefore detection is accurate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of the jaw of the present invention;
fig. 3 is a schematic structural view of the chuck according to the present invention.
In the figure: 1. a chuck; 2. clamping a step; 3. a claw; 4. a gear; 5. a main vent pipe; 6. a pressure gauge; 7. an electromagnetic valve; 8. a branch vent pipe; 9. air holes; 10. a fixed part; 11. a movable portion; 12. a horizontal vent portion; 13. a vertical vent portion; 14. screw holes.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
referring to fig. 1-3, a gear flat detection device includes:
the clamping device comprises a chuck 1, wherein clamping steps 2 are arranged at the inner side end parts of clamping jaws 3 of the chuck 1, the side surfaces of the clamping steps 2 are arc-shaped and matched with a gear and are just used for clamping the side surface of the gear, an air hole 9 is arranged inside each clamping jaw 3 of the chuck 1, and the tail end of each air hole 9 is positioned on the upper surface of the step of the clamping step;
the ventilation assembly comprises a main ventilation pipe 5 connected with a gas source, a pressure gauge 6 and an electromagnetic valve 7 are connected to the main ventilation pipe 5, branch ventilation pipes 8 corresponding to the clamping jaws 3 of the chuck 1 in number are further connected to the main ventilation pipe 5, and the branch ventilation pipes 8 are respectively and fixedly connected to air holes 9 of the clamping jaws 3.
The utility model discloses the process is as follows when using, several jack catchs 3 of chuck 1 are outwards opened earlier, open the back, the operator lays gear 4 on this clamping step, subsequently, jack catchs 3 move to the center and press from both sides gear 4 tightly, after gear 4 is pressed from both sides tightly, open solenoid valve 7, let in air in the main breather pipe 5 that connects with the air supply (the air supply can adopt air compressor to produce the air supply, also can use the sharing air supply of mill's inside), the air is discharged from a breather pipe 8, enter into jack catch 3's gas pocket 9 at last, and discharge from gas pocket 9, because the end of gas pocket 9 is in the step upper surface of clamping step, so gas pocket 9 will be blockked up by the lower surface of gear, at this moment, manometer 6 will show pressure, manometer 6 can be reached for the asia shi brand, digital display manometer 6 of type YSD-Y60-2, if the pressure displayed by the pressure gauge 6 is the same as the preset value (if the preset value is 0.6MPA, the pressure gauge 6 also displays 0.6MPA at the moment, the air hole 9 is blocked, and the gear is flat), the gear is flat, if the pressure displayed by the pressure gauge 6 is smaller than the preset value (if the preset value is 0.6MPA, the pressure gauge 6 displays 0.5MPA at the moment, the gear is not flat, and a part of gas escapes), at the moment, the gear is clamped again, and the gear can not be machined until the gear is flat.
