Description
Technical Field
The utility model relates to a frock fixture of using during machine part adds man-hour, specifically speaking relate to an automobile engine intake camshaft bearing cap processing fixture.
Background
In the prior art, the processing and preparation of the bearing cover of the air inlet camshaft of the automobile engine are realized by manufacturing a bearing cover blank by a die-casting process and then further finishing the cutting processing of a hole and a surface on a processing center. The basic structure of the intake camshaft bearing cover of the automobile engine in the prior art is provided with a bearing cover body, the bearing cover body is provided with a mounting surface at the top end and a pressing surface at the bottom end, left and right bolt mounting holes are formed in the bearing cover bodies positioned on the left and right sides, the distances from the axes of the left and right bolt mounting holes to the left and right side surfaces are unequal, semicircular camshaft mounting holes are formed in the mounting surface between the left and right bolt mounting holes, and the machining of the semicircular camshaft mounting holes is an important process for machining the intake camshaft bearing cover of the automobile engine in a machining center.
Air intake camshaft bearing cap blank adds man-hour in the processing center, needs frock fixture, and automobile engine air intake camshaft bearing cap among the prior art adds fixture has the fixture base of rectangle, and a plurality of cylinders are equipped with to the left and right bilateral symmetry of fixture base, even has the pawl on the piston rod of every cylinder, is located and is equipped with a plurality of locating pieces on the fixture base between left and right both sides cylinder correspondingly, automobile engine air intake camshaft bearing cap has the bearing cap body, and the left and right both sides of bearing cap body have left and right side bolt mounting hole, and the distance h between the axis of the left and right side bolt mounting hole of bearing cap body to the left and right flank of bearing cap body1And h2Unequal, and the left side and the right side of the adjacent positioning blocks are respectively provided with a cylindrical positioning pin corresponding to the bolt mounting holes on the left side and the right side of the bearing cover body.
When a semicircular camshaft mounting hole of an air inlet camshaft bearing cover of an automobile engine is machined, the camshaft bearing cover is clamped through the machining clamp in the prior art, the specific method is that the mounting surface of the camshaft bearing cover abuts against two adjacent positioning blocks, two corresponding positioning pins on the adjacent positioning blocks are inserted into two bolt mounting holes of the camshaft bearing cover, then a pressing surface of the camshaft bearing cover is pressed through a push claw on a cylinder piston rod, and the semicircular camshaft mounting hole of the camshaft bearing cover can be machined through a corresponding cutting machining tool of a machining center. When the processing fixture in the prior art is used for clamping, the camshaft bearing cover often falls on the fixture base, and because the cylinder is arranged on the base and the piston rod of each cylinder is connected with the push claw, the camshaft bearing cover is inconvenient to pick up again when falling below the piston rod connected with the push claw, time is wasted, the clamping efficiency of the camshaft bearing cover is reduced, and the processing efficiency of the camshaft bearing cover is indirectly reduced; in addition, when the camshaft bearing cover is installed, an adverse phenomenon sometimes occurs, so that the camshaft bearing cover needs to be detached from the processing clamp for reinstallation and installation, and the clamping efficiency of the camshaft bearing cover is also reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an automobile engine camshaft bearing cap processing fixture that admits air that conveniently picks up when camshaft bearing cap drops and clamps again to can improve camshaft bearing cap and clamp efficiency.
For solving the technical problem, the utility model discloses an automobile engine camshaft bearing cap processing fixture admits air has the fixture base of rectangle, and a plurality of cylinders are equipped with to the left and right bilateral symmetry of fixture base, even have the pawl on the piston rod of every cylinder, are located and are equipped with a plurality of locating pieces on the fixture base between the left and right both sides cylinder correspondingly, automobile engine camshaft bearing cap admits air has the bearing cap body, and the left and right both sides of bearing cap body have left and right side bolt mounting hole, and the axis of the left and right side bolt mounting hole of bearing cap body is to the distance h between the left and right flank of bearing cap body1And h2Unequal, the left and right sides of the adjacent positioning blocks are respectively provided with a cylindrical positioning pin corresponding to the bolt mounting holes on the left and right sides of the bearing cover body, and a clamping tool positioned between each cylinder and the corresponding positioning blockThe base is also provided with a cuboid auxiliary supporting block which is positioned below the corresponding push claw.
As the improvement of the utility model, the left and right sides of every locating piece still are equipped with a limit stop respectively, and the distance between limit stop and the adjacent cylindricality locating pin axis equals h1Or h2。
By adopting the clamping apparatus for processing the air inlet camshaft bearing cover of the automobile engine with the structure, as the rectangular auxiliary supporting block is also arranged on the clamping apparatus base positioned between each air cylinder and the corresponding positioning block, when the camshaft bearing cover falls off, the camshaft bearing cover only falls on the auxiliary supporting block, so that the camshaft bearing cover is convenient to pick up and clamp again, and the clamping efficiency can be relatively improved; because the left side and the right side of each positioning block are respectively provided with a limit stop, the distance between the limit stop and the axis of the adjacent cylindrical positioning pin is equal to h1Or h2And h is1And h2Unequal, when the camshaft bearing cover is clamped, the adjacent positioning blocks are positioned by the cylindrical positioning pins corresponding to the bolt mounting holes on the left side and the right side of the bearing cover body, and the limiting stop blocks are used for limiting, so that the phenomenon that the camshaft bearing cover is reversely mounted cannot occur, and the clamping efficiency of the camshaft bearing cover is improved.
