Abstract
The utility model relates to a handheld pneumatic reverse counter boring tool which comprises a handle, a positioning plate, a positioning pin, a connecting plate, a tool bit, a circular pin, a clamping block and a pneumatic device. The handheld pneumatic reverse counter boring tool is characterized in that a seam allowance groove is formed in the positioning plate and is matched with a kidney-shaped hole in the connecting plate, the pneumatic device can rotate around the circular pin, and a machine clamping blade is arranged on the tool bit. The handheld pneumatic reverse counter boring tool has the advantages that machining can be met under the condition of air source existence, the machine clamping blade is fixed on the tool bit by a screw, the cutting efficiency is high, and the replacement is simple and convenient.
Description
Technical field
The utility model relates to the hand-held pneumatic machine tools, particularly the anti-counter boring device of a hand-held pneumatic.
Background technology
Cause securing member finely not to be in contact with it owing to the out-of-flatness of the flange back side when two flange type parts connect, thereby bring the not fastening problem of connection, therefore usually need do the flat processing of reverse side ream the flange connecting hole; Existing processing method often is machine tool processing, and hole of every ream needs cutter head of dismounting, so efficient is lower; And part carrying before the processing and preparation such as fixing very easily cause the scuffing of colliding with of part; More advanced anti-ream technology is also arranged in the world today, and its blade can discharge and shrink with positive and negative the transferring of lathe main shaft automatically, thereby can accomplish anti-ream processing automatically; But this cutter all compares expensive; Anti-ream processing versatility to different apertures is not high, and needs high precision machine tool such as machining center to be used, and this requires for surface quality is not very high anti-ream processing; Increase the cutter purchase cost of company and the use cost of equipment undoubtedly greatly, thereby improved the processing cost of part.
Summary of the invention
The anti-counter boring device of hand-held pneumatic that the purpose of the utility model provides that a kind of processing cost is low, flexible operation, working (machining) efficiency height are applicable to the flat processing of flange connecting hole reverse side ream.
The utility model is to realize like this; It comprises handle, location-plate, alignment pin, connecting plate, cutter head, round pin; Clamp and pneumatic means is characterized in that on location-plate, having the seam groove, and the seam groove cooperates with mounting hole on the connecting plate; Pneumatic means rotates around round pin, and the clamped cutting bit sheet is housed on cutter head.
The utility model has the advantages that can satisfy processing having under the condition of source of the gas, cutter head is screwed the clamped cutting bit sheet, stock-removing efficiency is high, changes simple and convenient.
Description of drawings
Fig. 1 is the anti-counter boring device front view of hand-held pneumatic;
Fig. 2 is that the anti-counter boring device axle of hand-held pneumatic is surveyed view.
The specific embodiment
Shown in Fig. 1-2, the anti-counter boring device of this hand-held pneumatic comprises handle 1, location-plate 2, alignment pin 3, connecting plate 4, cutter head 5, round pin 6, clamp 7 and pneumatic means 8; On location-plate 2, have the seam groove, the seam groove cooperates with mounting hole on the connecting plate 4, and pneumatic means 8 is around round pin 6 rotations; The clamped cutting bit sheet is housed on cutter head 5, and transverse plane is substantially parallel with cutter head 5 cylindricals before the pneumatic means 8, and cutter head and part interfere in the time of can effectively preventing to cut; Add man-hour; At first location-plate 2 is adjusted to corresponding position, change corresponding alignment pin 3 according to the aperture, location again, pneumatic means is pulled dotted line position shown in the figure one after ready according to the flange thickness of part; Proficiency handle 1; Alignment pin 3 is inserted locating holes, and the another hand is opened pneumatic means 8 switches and is at the uniform velocity pressed, and arrives to limit the position and promptly accomplish the flat processing of reverse side ream in a hole during solid line position shown in the figure one.
