Description
Technical field
The utility model patent is related to reamer field more particularly to a kind of separate type reamer device.
Background technology
At this stage, after Workpiece boring, in order to improve the machining accuracy in hole, its surface roughness is reduced, can generally use hinge
Drilled on knife ream workpiece or reaming processing after hole.Currently, reamer blade is directly to be fixedly mounted on knife bar, still
Reamer belongs to vulnerable part, and it is jagged to will appear cutting edge in use, floats dumb, sharpening is not thorough, and the edge of a knife is not sharp
Situations such as, cause that the hole aperture increases of processing, aperture reduces, endoporus is non-round, inner bore surface roughness value is high, hole site precision is super
Difference, hole center line it is not straight a series of problems, such as.To ensure the machining accuracy of product, then the reamer more renewed in time is needed, is taken
With higher.
Utility model content
The purpose of the utility model is to overcome disadvantages described above, provides and a kind of not only having ensured product quality but also cost-effective point
From formula reamer device.
The technical solution of the utility model is a kind of separate type reamer device comprising blade, knife bar further include blade
Seat, the core that rises, adjusting rod, the knife bar are that a tail portion sets female hollow pipe, and two or more is equipped in the front end of knife bar
Axial notch, the both sides of groove cell wall are equipped with skewed slot, and the blade bearing is arranged in groove, and blade bearing both sides are equipped with and skewed slot
The convex block to match, convex block, which is caught in skewed slot, makes blade bearing be moved along skewed slot, the lower part of the blade bearing be equipped with annular groove and
Withstanding tight block, the adjusting rod be a hollow pipe, and the head of adjusting rod is equipped with to match with the annular groove of blade bearing lower part
The tail portion inner wall of ring slot, adjusting rod is equipped with internal thread, and the tail section exterior of adjusting rod is equipped with the internal thread phase with knife bar tail portion
The head of matched external screw thread, the core that rises is taper, and blade bearing is realized in withstanding tight block and the conical contact of the blade bearing lower part
Fixation, the tail portion of the core that rises is equipped with the external screw thread to match with adjusting rod tail portion internal thread, cutting blade is equipped on blade bearing top.
Preferably, it in order to protect knife bar internal structure, prevents sundries from entering, further includes baffle, the baffle is located at knife bar
Head end.
Preferably, the baffle is connect with cutter blade by fastener.
Preferably, the blade and blade bearing quantity are three pieces.
The advantageous effects of the utility model are, since reamer device is arranged to separate structure so that reamer knife
When piece is lost, it is only necessary to according to converted products material replace suitable material blade without polish the edge of a knife or directly more
Renew reamer, while rotation adjusting lever keeps blade radially movable, blade is adjusted and processes diameter.It both ensure that product in this way
High quality improves work efficiency, and can also process more products, has saved and has more renewed the required expense of reamer.
Description of the drawings

Fig. 2 is the utility model embodiment decomposition texture sectional view；
Fig. 3 is the utility model embodiment overall structure sectional view.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
With reference to attached drawing, a kind of separate type reamer device comprising cutting blade 5, knife bar 4 further include blade bearing 6, the core 2 that rises,
Adjusting rod 3, baffle 1, the knife bar 4 are that a tail portion sets female hollow pipe, set that there are three axial in the front end of knife bar 4
The both sides of groove 4-1, groove 4-1 cell walls are equipped with skewed slot 4-2, and the blade bearing 6 is arranged in groove 4-1, and 6 both sides of blade bearing are set
There is the convex block 6-1 to match with skewed slot 4-2, convex block 6-1, which is caught in skewed slot 4-2, makes blade bearing 6 be moved along skewed slot 4-2, the knife
The lower part of tablet seat 6 is equipped with annular groove 6-3 and withstanding tight block 6-2, and the adjusting rod 3 is a hollow pipe, and the head of adjusting rod 3 is set
There are the ring slot 3-1 that the annular groove 6-3 with 6 lower part of blade bearing matches, the tail portion inner wall of adjusting rod 3 to be equipped with internal thread,
The tail section exterior of adjusting rod 3 is equipped with the external screw thread to match with the internal thread of 4 tail portion of knife bar, and the head of the core 2 that rises is taper
2-1, the withstanding tight block 6-2 and taper 2-1 of 6 lower part of the blade bearing contact the fixation for realizing blade bearing 6, and the tail portion for the core 2 that rises is equipped with
The external screw thread to match with 3 tail portion internal thread of adjusting rod is equipped with cutting blade 5 on 6 top of blade bearing, and cutting blade 5 is common reamer
Piece, blade bearing 6 are that fastener is connect with cutting blade 5.The baffle 1 is located at 4 head end of knife bar, and baffle 1 is riveted with fastener
In 4 head end of knife bar, the blade 5 and 6 quantity of blade bearing are three pieces.
When work, cutting blade 5 being mounted on blade bearing 6, rotation adjusting lever 5, then adjusting rod 5 moves forward and backward in knife bar 4,
The skewed slot 4-2 of blade bearing 6 and cutting blade 5 along the both sides knife bar upper groove 4-1 is moved, and achievees the purpose that adjust processing diameter.Reamer
When piece 5 is slightly worn, only cutting blade 5 need to be ground again it is sharp, and in aforementioned manners adjust processing diameter after, can be continuing with,
