To achieve the goals above, the utility model adopts the technical scheme that

A kind of punching tooling for drive axle, including drill bit, the drill bit include knife handle, blade and point of a knife, the knife It is respectively the first groove, the second groove and third groove, the internal sizes of first groove that three grooves are uniformly provided on handle Conjunction is fixed with semiconductor cooling piece, and the inside gluing of second groove is fixed with flashing lamp, and the inside of second groove is glued It is fixed with temperature sensor, the semiconductor cooling piece, flashing lamp and temperature sensor are mounted on button cell and wireless signal Transmission module, the blade are to offer thread groove, and chip space, the chip space and thread groove are uniformly provided on the point of a knife Connection, and chip space and thread groove junction are smooth, the inside of the drill bit offers interior cold hole, and knife is run through in the interior cold hole Handle, blade and point of a knife.

Preferably, first groove, the second groove and third groove are all the same, and the first groove, the second groove and The notch of three grooves, which melts, is covered with glass cover.

Preferably, the semiconductor cooling piece, flashing lamp and temperature sensor is identical in quality.

Preferably, there are three the interior cold hole settings, interior cold hole is evenly distributed on the inside of drill bit, and the diameter in interior cold hole Account for the 10%-12% of knife handle diameter of section.

Preferably, the model DA-Pt100-CX of the temperature sensor.

Preferably, the model nRF24L01 of the wireless signal transmission module.

The beneficial effects of the utility model are:

1, the utility model can pass to control by 7 signal of temperature sensor when bit operation surface temperature is excessively high Device processed, then the flashing alarm of controller control flashing lamp avoids drill bit so as to remind operator to carry out the replacement of drill bit Fracture in hole, and cause drive axle scrap or Drill Crack splashing cause personnel, machinery damage.

2, the utility model controls semi-conductor electricity cold work by controller, so that the temperature at knife handle reduces, thus When preventing operator from dismantling drill bit, hand is scalded.

In summary, the utility model is capable of the punching of efficient and convenient progress drive axle, while can be in bit operation It alarms when the temperature is excessively high, operator is reminded to carry out more bit change.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-4, a kind of punching tooling for drive axle, including drill bit 1, drill bit 1 include knife handle 11,12 and of blade Point of a knife 13, being uniformly provided with three grooves on knife handle 11 is respectively the first groove 2, the second groove 3 and third groove 4, and first is recessed The inside gluing of slot 2 is fixed with semiconductor cooling piece 5, and the inside gluing of the second groove 3 is fixed with flashing lamp 6, the second groove 3 it is interior Portion's gluing is fixed with temperature sensor 7, the model DA-Pt100-CX of temperature sensor 7, the first groove 2,3 and of the second groove Third groove 4 is all the same, and the notch of the first groove 2, the second groove 3 and third groove 4 melts and is covered with glass cover, semiconductor cooling Piece 5, flashing lamp 6 and temperature sensor 7 are mounted on button cell and wireless signal transmission module, wireless signal transmission module Model nRF24L01, semiconductor cooling piece 5, flashing lamp 6 and temperature sensor 7 it is identical in quality, so that knife handle 11 is able to maintain Balance, blade 12 are to offer thread groove, and chip space 9 is uniformly provided on point of a knife 13, and chip space 9 is connected with thread groove, and is arranged It considers slot 9 to be worth doing and thread groove junction is smooth, the inside of drill bit 1 offers interior cold hole 8, and knife handle 11, blade 12 and knife are run through in interior cold hole 8 Point 13, there are three the interior cold settings of hole 8, and interior cold hole 8 is evenly distributed on the inside of drill bit 1, and the diameter in interior cold hole 8 accounts for knife handle 11 and cuts The top of the 10%-12% of face diameter, interior cold hole 8 are connected with the output end of coolant liquid.

In the present embodiment, when carrying out drive axle punching, drill bit 1 and drive axle surface high-speed friction rotation, coolant liquid from Interior cold hole 8, which enters in drill bit 1, to be cooled down, and chip is discharged from chip space 9 and thread groove, when drill bit 1 punch time service it is too long, When 1 surface temperature of drill bit is excessively high, signal is passed to controller by wireless signal transmission module by temperature sensor 7 at this time, control AT89C51 single-chip microcontroller is provided in device processed, then controller controls the flashing alarm of flashing lamp 6 by wireless signal transmission module, So as to reminding operator to carry out the replacement of drill bit 1, avoids the fracture of drill bit 1 in hole, and cause scrapping for drive axle, or The splashing of person's Drill Crack causes personnel, machinery damage, while when operator has found alarm, after closing alarm signal, controller Semi-conductor electricity cold 5 work of starting, so that the temperature at knife handle 11 reduces, thus when preventing operator from dismantling drill bit, scald Hand.
