Background
In traditional lathe processing, when carrying out batch product location, be through welding suitable round steel on the three-jaw chuck, the diameter and the length according to the work piece are processed into positioner to the good round steel of welding again, this kind of locate mode has destroyed the structure of original three-jaw chuck, and the type of dress card and the length of work piece receive the restriction greatly, can't carry out length control, if when processing the more work piece of type, need a plurality of three-jaw chucks to weld not unidimensional positioner, change different three-jaw chuck positioner according to the size of work piece makes a round trip, this kind of operation mode influences workman's machining efficiency greatly. Therefore, traditional lathe chuck positioning tool device can not be fit for the work piece location of various diameters and length, is unfavorable for the improvement of productivity ratio, and the limitation is great, and can destroy the original structure of positioner in the use, needs to study a three-jaw chuck positioner that can carry out length adjustment and need not to make a round trip to change.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a flower disc positioner that lathe was used for realize the work piece location of a pair three-jaw chuck dress card multiple size and length, remove the process that the tradition was made a round trip to change the three-jaw chuck from, realize the function that a claw was decided many, improve production machining efficiency.
In order to achieve the above object, the utility model provides a lathe chuck positioner, lathe chuck positioner includes chuck, sleeve and dabber, the sleeve is bottom surface open-ended columniform seamless pipe down, bottom surface horizontal direction symmetry is equipped with the sector of three unidimensional annuliform's chuck under the sleeve, the sleeve is provided with the square draw-in groove of fretwork along adjacent chuck limit, bottom surface central point puts the vertical direction setting on the sleeve the dabber, the dabber comprises screw rod and nut, the screw rod cooperatees with the nut size.
Preferably, the mandrel is a screw rod with the diameter of M20 × 200mm, the diameter of the sleeve is 80mm, and the flower disc is made of 8mm thick steel plates.
Preferably, the material of the lathe chuck positioning device is low-alloy high-strength steel or high-alloy medium-carbon steel.
Based on the technical scheme, the utility model has the advantages that: the device has good practicability and operability, is simple to operate and easy to master in the positioning process, has reliable positioning size, does not change the original structure of the three-jaw chuck, is suitable for positioning workpieces with various diameters and lengths, realizes the positioning of workpieces with various sizes and lengths by a pair of three-jaw chucks, removes the traditional process of replacing the three-jaw chuck back and forth, realizes the function of positioning multiple jaws, and improves the production and processing efficiency.
