Abstract
The utility model belongs to the technical field of metal cutting, in particular to a quick-changing reverse countersinking cutter, which is used for facing and processing a back surface of a flange connecting hole. The cutter comprises a cutter head (1) and a cutter rod (2); a kidney-shaped hole is arranged inside the cutter head (1), a kidney-shaped guiding segment and a locking segment are arranged at one end of the cutter rod (2), the locking segment in kidney shape is processed to form a 45-degree angle with a cross section of the guiding segment. By installing the cutter head into the cutter rod to the position of the locking segment, and then rotating the cutter head to a certain angle relative to the cutter rod, a user can lock the cutter head to the cutter rod, and achieve fast installation, locking, processing and utilization of the cutter within two to three seconds. The cutter solves the technical problems of low efficiency and poor processing accuracy of reverse countersinking in traditional processing, simultaneously has safe and reliable property and convenient manufacturing, and can be widely applied to the industry of machine processing.
Description
Technical field
The utility model belongs to the metal cutting technology field, particularly relates to a kind of cutter that is used for the flat processing of flange connecting hole reverse side ream.
Background technology
In tradition processing flange connecting hole reverse side technology, in order to finish reverse side spot-facing operation, usually adopt milling, boring process, the installation of cutter head and knife bar and clamp cumbersome, each clamping need compress with bolt, the once mounting clamping process needs 5～10 minutes, and efficient is low, and machining accuracy is difficult to guarantee.
The utility model content
The purpose of this utility model has provided a kind of cutter that is used for the flat processing of flange connecting hole reverse side ream, reverse side spot-facing process efficiency in the tradition processing is low to solve, the technical problem of machining accuracy difference, thereby shorten the production cycle, improve anufacturability, reduce and make the process technology difficulty, improve Economics of Processing, reduce cost.
The utility model has been taked following technical scheme: the anti-spot-facing cutter of a kind of quick change, comprise cutter head and knife bar, it is characterized in that: described cutter head is cylindrical, in the waist circular port is arranged; Described knife bar one end has guide section and locking section, and guide section is an oval shape, and 45 ° the oval shape that interlaces is processed in locking Duan Weiyu guide section cross section; By with cutter head through the guide section knife bar of packing into, to lock Duan Houzai with the relative knife bar of cutter head rotate to an angle the back both be locked at once and form.
The utlity model has following beneficial effect: cutter head, knife bar that the utility model adopts are waist shape structure, can in 2～3 seconds, realize Fast Installation and auto lock, not only working (machining) efficiency improves, and can improve machining accuracy, roughness can reach Ra6.3, guaranteed crudy, safe and reliable, easy to make, can be widely used in mechanical processing industry.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 7, the utility model is the anti-spot-facing cutter of a kind of quick change, and it comprises cutter head 1 and knife bar 2.
As shown in Figure 1 and Figure 2, cutter head 1 is made into cylindrical, in waist circular port 1a is arranged.
As shown in Figure 3, Figure 4, the guide section 2b of knife bar 2 is an oval shape, sees largest contours line among Fig. 4, and the locking section 2a of knife bar 2 sees Fig. 4 midship section outline line for to be processed into 45 ° the oval shape that interlaces with the guide section cross section.Cross section when cutter head 1 is packed knife bar 2 guide section 2b into as shown in Figure 5, wherein the waist circular port 1a in the cutter head 1 cooperates guiding with the guide section 2b of oval shape; Cross section when cutter head 1 is packed knife bar 2 locking section 2a into as shown in Figure 6, both lock at once after again cutter head 1 relative knife bar 2 being rotated 45 ° this moment.
The processing signal as shown in Figure 8; during work with workpiece 3 after Drilling machines bench 5 is fixing; knife bar 2 that Jia Gong spot-facing size Selection is suitable and cutter head 1 as required; knife bar 2 after passing workpiece 3 flange holes is packed cutter head 1 into; cross section when cutter head 1 is packed knife bar 2 into as shown in Figure 5; both lock at once after again cutter head 1 relative knife bar 2 being rotated 45 °; shown in the schematic cross-section 6 of cutter head knife bar locking; at this moment profile after the cutter head knife bar installation locking, opens drilling machine as shown in Figure 7; on carry drill press spindle 4 and can process the flange hole reverse side; finish the processing back and shut down, unload cutter head 1 and withdraw from, knife bar 2 can descend the preface operation.For external form complexity such as various cylinders, fuselage, crankcase, connected bodies, number of bolt hole is many, and anti-spot facing requirement is arranged, and can both realize by this kind cutter.
Claims (1)
1, the anti-spot-facing cutter of a kind of quick change comprises cutter head (1) and knife bar (2), it is characterized in that: be provided with waist circular port (1a) in the described cutter head (1); Described knife bar (2) is provided with guide section (2b) and locking section (2a), and guide section is an oval shape, and 45 ° the oval shape that interlaces is processed in locking Duan Weiyu guide section cross section; By the oval shape aperture of cutter head (1) being crossed the guide section knife bar (2) of packing into, to lock Duan Houzai with cutter head (1) relatively knife bar (2) rotate to an angle the back both be locked at once and form.
