Abstract
The utility model belongs to the technical field of mechanical processing, relating to a multitool turning device. Based on shortening the length of the chuck jaw and changing the original cutter frame structure, the minimum distance between the chuck and the main shaft is made to arrange a plurality of turning cutters conveniently without affecting the cutter frame and the chuck. Driven by an attachment clip, the bar enters the cutting section through the chuck with an even pace; the cutter frame is fixed on the main shaft, turning with the rotation of the main shaft. The utility model can be arranged conveniently; since the turning amount of each cutter is reduced, the finish turning of the bar from the rough turning is completed at a time, thus improving production efficiency; the product has the advantages of stable size and small scattering difference.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of multitool turning device
Background technology
At present, carrying out turning with two cuttves, is the method that generally adopts during bearing car system roller bar is produced.Wherein first cutter carries out the turning first time, and the turning amount is generally 0.75-1mm; Second cutter carries out the turning second time, and the total turning amount of secondary generally is no more than 2mm, and the bar size scattered error that processes is big, and roughness does not reach technological requirement, factually border measuring and calculating C
PK＜0.8, and production efficiency is low, and energy resource consumption is big.
Summary of the invention
Big in order to solve car system roller bar size scattered error, problem such as roughness does not reach technological requirement, and production efficiency is low.The utility model provides a kind of multitool turning device, is on the basis of existing knife rest, changes cutter frame structure, makes it install four simultaneously cutter carried out substep turning, and one time the turning amount is born jointly by four cuttves, the realization bar from rough turn to the one step completed target of finish turning.
Technical solution of the present utility model is: change into 40-50mm about the length 80mm with common chuck jaw, and change into 60-80mm about the length 40mm that knife rest is common, it is many turning cutter that the minimum range of chuck and main shaft can conveniently be installed, and knife rest and chuck are interfered.This device is made up of knife rest 6, knife rest 7, main shaft 8, chuck 9, turning cutter 4 and turning cutter 2, knife rest 6 and knife rest 7 are fixed on the main shaft 8, turning cutter 4 and turning cutter 2 are installed in respectively on knife rest 6 and the knife rest 7, are separately installed with turning cutter 5 and turning cutter 3 on knife rest 6 and knife rest 7
The beneficial effects of the utility model are,
Easy for installation, the production efficiency height, total turning amount is increased to 4.2mm on the basis of original 2mm; To the bar of turning amount greater than 2mm, its production efficiency has improved 1 times.Because every product size is stable the minimizing of the turning amount of cutter, scattered error is little, and base reaches 1.33, and roughness Ra drops to 15 μ m by 30 μ m, satisfies technological requirement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation
Among the figure, 1. bar, 2. turning cutter, 3. turning cutter, 4. turning cutter, 5. turning cutter 6. knife rests, 7. knife rest, 8. main shaft, 9. chuck, 10. chuck jaw.
The specific embodiment
Knife rest 6 and knife rest 7 are fixed on the main shaft 8,, turning cutter 4 and turning cutter 2 be installed in respectively on knife rest 6 and the knife rest 7, the length of chuck jaw 10 is 40-50mm, and the length of knife rest 6 and knife rest 7 is 60-80mm, is separately installed with turning cutter 5 and turning cutter 3 on knife rest 6 and knife rest 7.Turning cutter 4 is a first cutter, and bar 1 at the uniform velocity enters cutting region by chuck 9 under the drive of chuck, and knife rest is fixed on the main shaft, implements turning with main axis rotation.Implement turning for the first time, the turning amount is relatively large.Turning cutter 2 is second cutter, implements turning for the second time, and the turning amount is taken second place.Turning cutter 5 is the 3rd cutter, implements turning for the third time, and the turning amount is corresponding to be reduced.Turning cutter 3 is the 4th cutter, implements the 4th turning, and the turning amount reduces.
When bar 1 during by turning cutter 4, carry out the turning first time, and then turning cutter 2 carries out the turning second time, and turning cutter 5, turning cutter 3 carry out turning successively to final size.
