Description
Technical Field
The invention relates to a reamer for machining a precise hole, in particular to a mechanically clamped blade type adjustable reamer.
Background
Finish machining of the hole is typically accomplished using a reamer or boring tool. Because the reamer is an integral cutter, one reamer can only process a hole with one diameter, and must be scrapped once the reamer is worn. If the hole being machined is deeper, the reamer costs more. The boring cutter is a modularized cutter with adjustable diameter, and holes with different diameters and depths can meet the finish machining of the holes with different diameters and depths through modularized combination. The larger the diameter, the more suitable it is for boring with a boring tool. However, the boring cutter is used for single-edge cutting, the cutting force is unbalanced, and the unbalanced cutting force is counteracted by no support in the machining process, so that vibration is easy to generate when deep holes are machined, and the machining quality cannot be ensured. And the surface quality after processing is not higher than Ra0.8 due to the point contact mode, the blade is worn faster, the diameter is often required to be adjusted and the blade is required to be replaced, and the diameter is required to be adjusted every time the blade is replaced. The use is time-consuming and labor-consuming.
The reamer is designed with the adjustable cutter clamping blade, so that the production and use cost of the reamer can be reduced. Especially when processing the major diameter deep hole, only scrap the blade after the cutter wearing and tearing, the reamer pole can use for a long time.
Disclosure of Invention
The invention aims to solve the technical problem of providing a mechanically clamped blade type adjustable reamer.
The invention solves the technical problems by the following technical proposal: a mechanically clamped, blade-type adjustable reamer comprising: the cutter body comprises a connecting pipe and rotating plates, wherein the connecting pipe is cylindrical, a plurality of rotating plates are uniformly distributed on one side of the connecting pipe, blade grooves are formed in the side faces of each rotating plate, the screws are inserted into the blade grooves, the screws are used for installing the reaming plates in the blade grooves, an eccentric pin hole is formed in the side face of each rotating plate of the cutter body, and the eccentric pins are inserted into the eccentric pin holes.
Preferably, the hinge blade has cutting edges on both sides.
Preferably, the head part of the eccentric pin is provided with an eccentric cylinder, and the tail part of the eccentric pin is provided with a cylindrical pin.
Preferably, a sealing ring groove is arranged between the eccentric cylinder and the cylindrical pin, and a sealing ring is arranged in the sealing ring groove.
Preferably, the eccentric cylinder contacts with the hinge blade installed in the blade slot, and the side surface of the eccentric cylinder is provided with a hexagonal rotation hole.
Preferably, the cylindrical pin is inserted into the eccentric pin hole.
The invention has the advantages that: the invention can stably process holes and deep holes with high surface quality by adopting a multiple-edge cutting design. Only the blade needs to be replaced after the cutter is worn, the reamer rod can be used continuously, and the use cost of the cutter during processing of the large-diameter hole is reduced. The cutter-clamping type adjustable reamer can adjust the diameter through externally rotating the hexagonal rotating hole, so that the processing quality is improved, and the service life is prolonged.
