Abstract
The utility model relates to an adjustable reamer for processing and repairing a valve-seat bore of an engine. The utility model has the structure that the utility model is composed of a reamer rod, a positioning guide rod, a boosting holding handle, etc. The utility model is mainly characterized in that one side of the reamer rod adopts a fastening adjustment plate and a positive and negative dual-purpose double-edge blade which is matched with the fastening adjustment plate. The reamer can adjust processing diameters and angles of used blade according to need. Under the condition that the blade is not replaced, the utility model realizes that the valve-seat bore or a raceway supporting bore with different diameters and different taper angles can be reamed, bored and processed. The utility model has the advantages of simple structure and flexible use.
Description
The utility model relates to a kind of metal-cutting machine tool of valve-seat bore of fixing over an engine that is used to process.
Prior art is not have controllability and improved on serviceability at " complete valve seating typing reamer ".In the Chinese patent open and authorize have 94111185.7,9521731.4 and 95238064.1 etc. to introduce several relatively more novel adjustable air valve seat reamers respectively.Above technology is respectively by changing the collapsing length of blade on cutter hub to realize the processing to different-diameter, by selecting for use typing angle blade to realize processing to different cone angle, strictly say, such serviceability can not think to realize fully adjustable function truly, because be not to adopt regulating measure to finish for the processing of different cone angle.The processing method of this and complete typing reamer does not have the difference of essence, and different is, and reamer set changes is typing cutter piece, is the typing blade and the latter changes, so the serviceability of existing adjustable reamer still exists limitation with not enough.
The purpose of this utility model is the valve seat reamper that provides a kind of cutting diameter and cutting angle to regulate at the deficiencies in the prior art.
The purpose of this utility model takes following measure to realize: this reamer is made up of knife bar, location guide, afterburning handle etc., principal character is in a side of knife bar the fastening adjustment plate is arranged, adjustable plate and knife bar axis tilt, fan-shaped adjustment hole and microscler adjustment hole are arranged thereon, blade is fastened on the adjustable plate by fan-shaped adjustment hole and microscler adjustment hole, blade is that tow sides respectively have a cutting edge, and its shape has the perpendicular substantially open slot of knuckle and two.
Accompanying drawing and drawing explanation:
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the partial right side view of knife bar of the present utility model and adjustable plate junction;
Fig. 3 is the utility model blade moulding schematic diagram, and wherein A is a reverse side, and B is positive.
Wherein: [1]-knife bar, [2]-fastening adjustment plate, [3]-location guide, [4]-blade, [5]-afterburning handle, [6]-fan-shaped adjustment hole, [7]-microscler adjustment hole, [8], [9]-open slot.
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:
The utility model knife bar [1] is the jockey of reamer, and the upper end of knife bar [1] can be connected with afterburning handle [5], through the pressure of both hands, and the reinforcing effect when realizing ream; Bottom surface, knife bar lower end has internal thread to be connected with location guide [3] with the taper hole structure; One side of knife bar is fastening adjustment plate [2].Adjustable plate and knife bar are structure as a whole, and tilt with the knife bar axis, are undertaken fastening and adjusting cutting position by fan-shaped adjustment hole [6] on the plate and microscler adjustment hole [7] blade.Location guide [3] upper external screw thread and cone cooperate with the knife bar bottom outlet, play the connection effect, and cone is following to be the guide rod part, cooperates with valve guide bushing, plays the role of positioning when ream.Blade [4] is the reversible double-edged blade, and its shape has knuckle and two perpendicular substantially open slots [8] and [9], blade is fastened on the adjustable plate can carries out ream.
The utility model fastening adjustment panel assembly [2] is a slab construction, is the key of present technique.The shape of two adjustment holes and relative position are to design for the regulatory function that realizes blade on the adjustable plate.Fan-shaped adjustment hole is mainly used in the adjusting of cutting angle, and microscler adjustment hole is mainly used in the adjusting of radius of clean-up, and two holes have the fastening and positioning action of blade again simultaneously.When adjusting the cutting position of blade, blade is moved forward and backward along microscler adjustment hole, can realize the adjusting of radius of clean-up; Blade is rotatablely moved along fan-shaped adjustment hole, can realize cutting the adjusting of tapering.
The knuckle of blade [4] modelling feature and cone angle are for adapting to the design feature of adjustable plate, making blade have bigger adjustable extent, and be irrelevant with the processing cone angle of valve-seat bore.Two open slots on the blade and corresponding the communicating in adjustable plate two holes, play the effect of fastening blade, when blade plane and adjustable plate plane were overlapping, open slot and adjustment hole were also simultaneously overlapping, and form two location fulcrums, promptly with overlapping last fulcrum of scallop hole and the lower fulcrum overlapping with elongated hole.With bolt pass two name a person for a particular job adjustable plate and blades fastening after, do not have other spacing strong points between two fulcrums, so do not produce movement and deformation behind the fastening location, two planes.
Regulate the blade cut radius, can process the valve-seat bore diameter of 25mm-75mm scope; Regulate blade cutting angle can between 15 °-90 ° arbitrarily the seat hole cone angle at angle process; Wherein clamping adjustable-angle in blade front is 15 °-50 °, and blade reverse side clamping adjustable-angle is between 40 °-90 °.In order to guarantee the adjusting accuracy of reamer, the utility model design also has been equipped with special-purpose angular adjustment dip stick.The adjustable reamer that the utility model provides adopts the ordinary carbon steel material, and tool surface is through chromium plating or method surface treatment such as turn blue.Also can select thermosetting good engineering plastics for use.Blade will have enough rigidity and intensity, should select the quality carbon steel manufacturing for use, and through modifier treatment.The cutting tip of blade is the high-ductility hard alloy, is welded as a whole with blade, and the blade positive and negative all requires the higher depth of parallelism and surface smoothness.
The utility model has the advantages that simple in structure, use flexibly, can satisfy the valve of different-diameter and cone angle The processing request in seat hole.
Claims (2)
1, a kind of adjustable air valve seat reamer, form by knife bar [1], location guide [3], afterburning handle [5] etc., it is characterized in that: the side at knife bar [1] has fastening adjustment plate [2], adjustable plate and knife bar axis tilt, fan-shaped adjustment hole [6] and microscler adjustment hole [7] are arranged thereon, and blade [4] is fastened on the adjustable plate by fan-shaped adjustment hole and microscler adjustment hole.
2, adjustable air valve seat reamer according to claim 1, it is characterized in that: blade [4] respectively has a cutting edge for tow sides, and its shape has the perpendicular substantially open slot of knuckle and two [8], [9].
