Description
Technical Field
The utility model relates to a positioner field especially relates to a numerical control lathe's positioner.
Background
Numerical control lathe work often has the singleness processing of wholesale nature, the uniformity that will keep the processing product batch all will fix a position the product when the clamping, current locate mode need be at a positioner of lathe tool shelf location, all need move positioner to fixed position back during location every time, lean on the product on the location backer and tighten the product again, operating space is little, complex operation, and the location backer moves the accuracy of fixed position relatively poor, be unfavorable for the uniformity after the product processing, the qualification rate is lower. The utility model discloses, having fixed positioner, having ensured the accuracy of locating position, clamping product operation space is big, is favorable to the accurate nature of clamping, and uniformity after the product processing has improved product percent of pass and machining efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a numerical control lathe's positioner to solve the problem that proposes among the above-mentioned background art.
A positioning device of a numerical control lathe comprises a positioning rod, a locking sleeve and a tensioning nut; the positioning rod sequentially comprises a thin straight rod, a thick straight rod, a conical rod and an external thread rod; the locking sleeve is step-shaped, and two ends of the locking sleeve are respectively provided with 4 elastic open grooves along the axial direction; one end of the external thread rod of the positioning rod penetrates through the locking sleeve, and the tensioning nut is in threaded connection with the external thread rod of the positioning rod.
Further, the device is installed in a chuck of the numerically controlled lathe.
Furthermore, the diameter of the end face of the connecting end of the conical rod and the external thread rod is smaller than the inner diameter of the locking sleeve.
When the first product is processed, the positioning rod is arranged in the locking sleeve, then the numerical control lathe chuck is arranged, and the tensioning nut is screwed. After a processed product is loaded into the numerical control lathe chuck, one end of a positioning rod of the positioning rod device is leaned against the processed product, the tensioning nut is rotated to expand the locking sleeve by the conical surface of the positioning rod, and the positioning device is fixed on the numerical control lathe chuck, so that the positioning effect is achieved. During batch processing, the product is only required to be loaded into the numerical control lathe chuck and then pushed to the bottom for tightening.
Preferably, the positioning rod is machined from 45# steel.
Preferably, the locking sleeve is made of a spring steel material, and the heat treatment hardness is HRc 40-50.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
A positioning device of a numerical control lathe comprises a positioning rod 1, a locking sleeve 2 and a tensioning nut 3; the positioning rod 1 sequentially comprises a thin straight rod 1-1, a thick straight rod 1-2, a conical surface rod 1-3 and an external thread rod 1-4; the locking sleeve 2 is step-shaped, and two ends of the locking sleeve are respectively provided with 4 elastic open grooves along the axial direction; one end of the external thread rod 1-4 of the positioning rod 1 penetrates through the locking sleeve, and the tensioning nut 3 is in threaded connection with the external thread rod 1-4 of the positioning rod.
Further, the device is installed in a chuck 4 of a numerically controlled lathe.
Furthermore, the end face diameter of the connecting end of the conical rod 1-3 and the external thread rod 1-4 is smaller than the inner diameter of the locking sleeve 2.
When the first product is processed, the positioning rod is arranged in the locking sleeve, then the numerical control lathe chuck is arranged, and the tensioning nut is screwed. After a processed product is loaded into the numerical control lathe chuck, one end of a positioning rod of the positioning rod device is leaned against the processed product, the tensioning nut is rotated to expand the locking sleeve by the conical surface of the positioning rod, and the positioning device is fixed on the numerical control lathe chuck, so that the positioning effect is achieved. During batch processing, the product is only required to be loaded into the numerical control lathe chuck and then pushed to the bottom for tightening.
Preferably, the positioning rod 1 is machined from 45# steel.
Preferably, the locking sleeve 2 is made of spring steel materials, and the heat treatment hardness is HRc 40-50.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
