Marked in the figure: 1- base of the carrier head, 2- sleeve, 3- collet, 4- pull rod, 5- positioning bolt, 6- tension device mounting plate, 7-
Collet limited block.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and specifically
The utility model is described in detail in embodiment.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of cartridge device of adjustable clamping length, including base of the carrier head 1, sleeve 2, collet 3, drawing
Bar 4, positioning bolt 5 and tension device mounting plate 6, clamping part is collectively formed in the base of the carrier head 1, sleeve 2 and collet 3, described
The pedestal of base of the carrier head 1 is equipped with axially extending bore, and 2 interference of sleeve is connected in the axially extending bore of base of the carrier head 1, and the inside of sleeve 2 is equipped with
Hollow cavity, one end of the hollow cavity are tubaeform (pyramid type) opening, are fitted with collet 3 inside the hollow cavity of casing 2, described
Collet 3 is equipped with axial workpiece installing hole, and one end of collet 3 is the inverted cone knot matched with 2 horn opening of sleeve
Structure, the other end are threadedly coupled with pull rod 4, and the inside of collet 3 is equipped with limit cavity, and interference fit is connected in the limit cavity
Collet limited block 7, the collet limited block 7 are equipped with axial threaded hole, and the axial threaded hole internal screw thread is connected with positioning bolt
5, the head of the positioning bolt 5 contacts limit to the workpiece for the workpiece installing hole for passing through collet 3, passes through rotational positioning bolt 5
Relative to the extension elongation of collet limited block 7, control workpiece by clamping length, realize the adjusting of the clamping length of workpiece.
One end of pull rod 4 is the threaded ends of collet 3, and the other end is handle end, and the handle end passes through tension device
Pilot hole on 6 bottom plate of mounting plate, the pilot hole be both used as the motion guide of pull rod 4, but also as the supported hole of pull rod 4.
Tension device mounting plate 6 is whole U-shaped, offers horizontal sliding slot on the side plate of 6 two sides of tension device mounting plate, bolt passes through
Base of the carrier head 1 is connect by sliding slot with tension device mounting plate 6, to make base of the carrier head 1 that can slide along sliding slot, adjusts 1 phase of base of the carrier head
