Abstract
A large-travel synchronous structure slitting machine tool rotary guide sleeve comprises a rotary guide sleeve unit, wherein a synchronizer arranged on the main shaft unit of the rotary guide sleeve unit is connected with two synchronous belts, and the two synchronous belts are respectively overlapped on a synchronous belt wheel and a ball spline synchronous belt wheel, the synchronous belt wheel is installed on the end portion of a ball spline, the ball spline synchronous belt wheel is installed on the ball spline, and the two ends of the ball spline are installed on a bracket. The utility model adopts the method of connecting the synchronizer in parallel as a driving structure did not be connected in series between the main shaft and the rotary guide sleeve, therefore, the travel is two times than that of a series structure, and the one-time clamping turning travel of a work-piece is effectively increased.
Description
Technical field
The utility model belongs to the accessory of machining equipment technical field, particularly lathe.
Background technology
Longitudinal cutting machine tool pilot bushing structure generally has fixed guide lining and 2 kinds of versions of rotary steering lining.Non-difficult-to-machine material processing or high-precision part add man-hour, use the fixed guide lining, and defective material is short; But rotary steering lining High-speed machining, the processing of particularly suitable thin and long shafts part, but defective material is longer, it is short once to clamp turning length, and simultaneously because to make assembly difficulty big, domestic lathe producer seldom relates to, CK1116 as Ningjiang Machine Tool Plant only has fixed guide lining pattern, stroke 200; The DB16 of Dalian Machine Tool Factory only has fixed guide lining pattern, stroke 175; The G-Z16 fixed guide lining stroke 170 of Guangzhou Machine Tool Plant, the rotary steering lining has only 75.External lathe producer such as open country, palace (Miyano) A16 lathe, fixed guide lining pattern, turning length 135, rotary liner 57, the SB-16 lathe of Star, fixed guide lining pattern, turning length 205, rotary liner 155, the BO20A-V lathe of (TSUGAMI) on Tianjin, fixed guide lining pattern, turning length 210, rotary liner 80, Xi Li company utilizes THK ball spline rotatablely moving by the synchronous band sychronisation that is delivered to the rotation guide pin bushing in parallel main shaft, obtained big stroke and turning length (fixed guide lining stroke 240mm) that the rotary steering lining once clamps feeding 210mm, defective material length has only 170mm (fixed guide lining 140).
Summary of the invention
The utility model advantage is a kind of big stroke synchronization structure longitudinal cutting machine tool rotation guide pin bushing of design, with a clamping turning of effective increase workpiece stroke.
Specifically, big stroke synchronization structure longitudinal cutting machine tool rotation guide pin bushing, has rotation guide pin bushing unit, sychronisation on the main axle unit of rotation guide pin bushing unit is connected with two synchronous bands, two synchronous bands are overlapped on respectively on synchronous pulley and the ball spline synchronous pulley, synchronous pulley is installed in the ball spline end, and the ball spline synchronous pulley is installed on the ball spline, and the ball spline two ends are rack-mount.
The utility model is not owing to have the tandem sequence structure in main shaft, rotation between the guide pin bushing, but adopts the method for synchronizer structure in parallel, and stroke can reach 2 times of cascaded structure, so effectively increased a clamping turning of workpiece stroke.The rotary-type strain spline that rolls is to have the operation characteristic of high rotating speed, high accuracy and rigidity while the linear motion system that rotates, transmits moment of torsion.
Description of drawings
Accompanying drawing is the utility model structural representation.
The figure number explanation: 1. synchronous pulley 2. ball spline synchronous pulleys 3. ball splines 4. supports 5. spline housing bearings 6. types are with 7. main axle units, 8. rotation guide pin bushing unit synchronously.
The specific embodiment
As shown in the figure, big stroke synchronization structure longitudinal cutting machine tool rotation guide pin bushing, has rotation guide pin bushing unit 8, it is that sychronisation on the main axle unit 7 of rotation guide pin bushing unit 8 is with 6 to be connected with two synchronously, be with 6 to be overlapped on respectively on synchronous pulley 1 and the ball spline synchronous pulley 2 synchronously for two, synchronous pulley 1 is installed in ball spline 3 ends, and ball spline synchronous pulley 2 is installed on the ball spline 3, and ball spline 3 two ends are installed on the support 4.The rotatablely moving of main shaft (electric main shaft), feeding vertically and rapid traverse move through and connect main axle unit and the spline housing bearing of synchronizer unit, the synchronous pulley of front-end of spindle, the synchronous pulley and the ball spline that are installed on the ball spline pass to the rotation guide pin bushing synchronously after 44/60 * 60/44 deceleration and raising speed, realize the synchronous stable and continuous running of main shaft, rotation guide pin bushing.
Claims (1)
1, big stroke synchronization structure longitudinal cutting machine tool rotation guide pin bushing, has rotation guide pin bushing unit (8), it is characterized in that the sychronisation on the main axle unit (7) of rotation guide pin bushing unit (8) is connected with two synchronous bands (6), be with (6) to be overlapped on respectively on synchronous pulley (1) and the ball spline synchronous pulley (2) synchronously for two, synchronous pulley (1) is installed in ball spline (3) end, ball spline synchronous pulley (2) is installed on the ball spline (3), and ball spline (3) two ends are installed on the support (4).
