Problems solved by technology

[0002] In the current background technology, the locking method of the knife handle of the turret adopts the rear-pull locking method. There is a pull nail at the end of the knife handle, and the oil pressure controls the knife cylinder. When working, the mechanical claw grabs the pull nail and then pulls it, and tightens the handle; the general turret needs to be equipped with a VDI tool holder ( Figure 2-1 ), which are not interchangeable in turning, milling, boring, drilling, and tapping. They are all special parts. Not only is the VDI tool seat expensive, the tool holder is not easy to replace, and the tool holder is prone to loosening during processing. When it is necessary to process porous parts, it is necessary to process step by step. Drilling and tapping cannot be completed at one time. For different workpieces, multi-axis devices cannot be installed, so man-hours are wasted and the processing efficiency is not good. In addition, in the spindle transmission mode, generally The main shaft transmission adopts spline transmission, and the spline manufacturing process is cumbersome and expensive
The position of the turret is easy to yaw, and the turret moves up and down (because the turret only performs radial rotation), which cannot effectively reduce friction; in addition, the rotating structure of the turret adopts a two-plate clutch structure. When the turret needs to rotate, The turret can only rotate when the indexing tooth plate is separated from the rising base, so the rotation accuracy is low and the stability is not good

Embodiment 1

[0017] Embodiment 1: see attached Figure 1 to Figure 5 . It includes Dota ( Figure 5-1 ), the guide seat in the turret ( Figure 4-4 ) indirectly fastened to the base ( Figure 5-4 ), a round hole is opened on the normal surface of the guide seat ( Figure 4-3 ), so that the main shaft drive shaft ( Figure 4-2 ) is connected to the transmission, and the outer circular surface of the guide seat has a glyph guide groove ( Figure 4-5 ), the distance between the upper and lower ends is symmetrical to the center of the circular hole on the normal plane. One-shaped flat head handle seat ( figure 1 -8) The tail is formed into an inline flat head and is located in the inline guide groove in the guide seat. The inline flat head handle seat cooperates with the inline guide groove on the guide seat and rotates along the guide seat. wear plate ( Figure 4 -6) It is built into the inline guide groove of the guide seat and the wear-resistant sheet is located on the left side a...

Embodiment 2

[0026] Embodiment 2: On the basis of embodiment 1, the method of rotation of the rotary turret, when the turret rotates, drives the inline flat head handle seat ( figure 1 -8) With the guide seat inline guide groove ( Figure 4-5 ) for a 360-degree circular rotation, and after the turret rotates at a specific angle, the flat head at the end of the flat head handle seat is transferred into the flat groove of the main shaft drive shaft ( Pic 4-1 ) after anastomosis, the main shaft drive shaft is driven by the servo motor ( Figure 4-2 ) rotation, so that the flat-shaped flat head handle seat is rotated, and at this time, the V-shaped groove handle ( Picture 1-1 ) and tools to process the parts.

Embodiment 3

[0027] Embodiment 3: with reference to attached image 3 . The rotary turret includes a turret, and the turret is divided into four types: 4-axis, 6-axis, 8-axis, and 12-axis, and the turret is equipped with a multi-axis device 1 .

Abstract

The invention relates to a turret type rotary tool turret used for turning and milling tool turrets and machining centers of NC lathes and a rotation method. A toolholder adopts the locking structure of a locknut and uses a V-shaped groove of a V-shaped groove toolholder; the V-shaped groove toolholder is locked by rotating the locknut clockwise and is loosened by rotating the locknut counterclockwise so as to be convenient for realizing the functions of installing, fixing and taking out the V-shaped groove toolholder and replacing multi-spindles; spindle transmission adopts the straight concave-convex connection transmission type; the tool turret rotation adopts the structure of a three-plate clutch which is driven to rotate by a high-precision worm gear and a worm. The invention has the following advantages: 1. short replacement time, fast speed and convenient replacement of V-shaped groove toolholders; 2. good functions of installing and replacing multi-spindles, one-time completion of drilling and tapping, shortened operation time and greatly improved machining efficiency; 3. great bearing capacity, good structure rigidity, long service life, simple machining, low manufacturing cost and convenient equipment maintenance and repair; 4. high rotary precision and good stability.

Description

technical field [0001] The invention relates to a turret-type rotating turret and a rotating method for CNC lathe turning, milling, compound turret and machining center machine. The turret is divided into four major specifications: 4-axis, 6-axis, 8-axis and 12-axis , which belongs to the field of rotary turret manufacturing. Background technique [0002] In the current background technology, the locking method of the knife handle of the turret adopts the rear-pull locking method. There is a pull nail at the end of the knife handle, and the oil pressure controls the knife cylinder. When working, the mechanical claw grabs the pull nail and then pulls it, and tightens the handle; the general turret needs to be equipped with a VDI tool holder ( diagram 2-1 ), which are not interchangeable in turning, milling, boring, drilling, and tapping. They are all special parts. Not only is the VDI tool seat expensive, the tool holder is not easy to replace, and the tool holder is prone t...
