Abstract
The invention discloses an adjustable grinding rod which comprises a rod body, wherein a cutter handle is fixedly arranged on the rod body; one end of the rod body is provided with a conical rod section; a grinding sleeve is arranged in match with the upper conical surface of the conical rod section; a threaded section is arranged on the inner side of the conical rod section; an adjusting screw sleeve is arranged in match with the threaded section; an inner threaded hole is formed in the outer end surface of the conical rod section; the rear end of the grinding sleeve is sleeved with a positioning sleeve; the positioning sleeve is fixedly connected with the conical rod section through an adjusting bolt. By adjusting a locking mechanism, the outer diameter of the grinding sleeve meets the application requirements, and an adjusting pressing plate moves along the axial direction because of an M8 locking bolt, so that the grinding sleeve is driven to move, the outer diameter of the grinding sleeve is increased to be expected size and subsequently the adjusting sleeve is locked.
Description
Technical field
The present invention relates to adjustable milling bar.
Background technology
Milling bar of the prior art has following defect: 1, adjustable extent is very little; 2, outside dimension regulates rule of thumb that formula calculates 3, abrasion site is insecure, there will be dropping situations; 4, the not reverse adjusting of grinding sleeve.
Summary of the invention
The object of this invention is to provide a kind of adjustable milling bar, grinding sleeve and cone bar interworking, by regulating retaining mechanism to make grinding sleeve outside dimension meet instructions for use, by M8 clamping screw, make to regulate pressing plate to move vertically, thereby drive grinding sleeve to move, its outside dimension is increased, lock regulating sleeve after reaching required size.
Technical scheme of the present invention is as follows:
Adjustable milling bar, include the body of rod, on the body of rod, be installed with handle of a knife, body of rod one end has cone bar section, cone match grinding sleeve in described cone bar section, and cone bar section inner side is thread segment, on thread segment, be screwed with Adjusting bolt Adjusting screw, cone has internal thread hole on bar section outer face, and grinding sleeve rear end press-fits positioning sleeve, and positioning sleeve is fixedly connected in cone bar section by adjusting bolt.
Described grinding sleeve has the inner conical surface coordinating with cone bar section.
Grinding sleeve and cone bar interworking, by regulating retaining mechanism to make grinding sleeve outside dimension meet instructions for use, by M8 clamping screw, make to regulate pressing plate to move vertically, thereby drive grinding sleeve to move, its outside dimension is increased, lock regulating sleeve after reaching required size.
Beneficial effect of the present invention:
1, can make number of times increase, adjustable extent increases 0-0.2mm; 2, outside dimension regulates rule of thumb that formula calculates 3, abrasion site is firm, there will not be dropping situations; 4, can realize the reverse adjusting of grinding sleeve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, adjustable milling bar, includes the body of rod 1, is installed with handle of a knife 2 on the body of rod 1, body of rod one end has cone bar section 3, cone match grinding sleeve 4 in cone bar section 3, grinding sleeve 4 has the inner conical surface coordinating with cone bar section 3, and cone bar section 3 inner sides are thread segment, on thread segment, be screwed with Adjusting bolt Adjusting screw 4, cone has internal thread hole 5 on bar section 3 outer faces, and grinding sleeve 4 rear ends press-fit positioning sleeve 6, and positioning sleeve 6 is fixedly connected in cone bar section by adjusting bolt 7.
Claims (2)
1. adjustable milling bar, include the body of rod, on the body of rod, be installed with handle of a knife, it is characterized in that, body of rod one end has cone bar section, cone match grinding sleeve in described cone bar section, cone bar section inner side is thread segment, is screwed with Adjusting bolt Adjusting screw on thread segment, and cone has internal thread hole on bar section outer face, grinding sleeve rear end press-fits positioning sleeve, and positioning sleeve is fixedly connected in cone bar section by adjusting bolt.
2. adjustable milling bar according to claim 1, is characterized in that, described grinding sleeve has the inner conical surface coordinating with cone bar section.
