Abstract
The utility model discloses an adjustable grinding bar which comprises a bar body, wherein the bar body is fixedly provided with a cutter handle, wherein one end of the bar body is provided with a conical bar section which is in conical fit with a grinding sleeve; a thread section is arranged on the inner side of the conical bar section and is screwed with an adjusting thread sleeve; an inner thread hole is formed in the outer end surface of the conical bar section; a positioning sleeve is arranged at the rear end of the grinding sleeve in a pressing manner, and is fixedly connected with the conical bar section though an adjusting bolt. Through an adjusting locking mechanism, the outer diameter size of the grinding sleeve meets the using requirement, an adjusting pressing plate moves axially through an M8 locking bolt, so that the grinding sleeve is driven to move, the outer diameter size is increased, and the adjusting sleeve is locked after the required size is reached.
Description
Technical field
The utility model 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 that rule of thumb formula calculates 3, abrasion site is insecure, there will be dropping situations; 4, the not reverse adjusting of grinding sleeve.
Utility model content
The purpose of this utility model 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, make to regulate pressing plate to move vertically by M8 clamping screw, thereby drive grinding sleeve to move, its outside dimension is increased, lock regulating sleeve after reaching required size.
The technical solution of the utility model 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, make to regulate pressing plate to move vertically by M8 clamping screw, thereby drive grinding sleeve to move, its outside dimension is increased, lock regulating sleeve after reaching required size.
The beneficial effects of the utility model:
1, can make number of times increase, adjustable extent increases 0-0.2mm; 2, outside dimension regulates that rule of thumb 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 utility model.
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.
