Abstract

The utility model discloses an aluminum wheel gate-removal drilling machine which comprises a substrate (1), a clamping apparatus (2), a drilling-milling tool (5) and a main shaft (6), and is characterized in that a shaft shoulder (8) is arranged on a terminal of the main shaft (6) of the drilling machine, a wheel lip plane probing arm (4) is mounted on the main shaft (6) and positioned with the shaft shoulder (8) in a contact mode, a wheel lip plane triggering sensor (7) is mounted on the wheel lip plane probe arm (4), and trigger points of the triggering sensor (7) are parallel and level to a peak horizontal plane of the drilling-milling tool (5). The drilling machine can depend on equipment and the tool to directly ensure the size from a process wheel lip end face to a central gate boss bringing significant influence to the flow forming process, avoids errors caused by indirect detection and artificial operation, and at the same time, also reduces detection intensity of operators, and improves machining efficiency.

Description

A kind of aluminum vehicle wheel removes the cast gate drilling machine

Technical field

The utility model relates to a kind of drilling machine, relates to specifically a kind of casting spinning combination process aluminum vehicle wheel and removes the cast gate special drill press.

Background technology

Low pressure casting is the most a kind of forging type of present cast aluminum-molykote composite material wheel production application, because the cast gate of low pressure casting is positioned at wheel center, needs to adopt drilling machine that cast gate is bored after the casting.For pressure common casting wheel, general drilling machine can satisfy the cast gate requirement.But the wheel for casting spinning combination process, the spinning operation is arranged after the casting one, this spinning operation needs strict control wheel technique wheel lip to the size of trumpet assembly boss, the prior art common driller is this size of manual control indirectly, because the casting wheel blanks has certain, skimble-scamble distortion, this just causes indirectly controlled wheel technique wheel lip to have the deviation of 1mm to 2mm to the size of trumpet assembly boss, and this will have a strong impact on the production of spinning operation.Adopt simultaneously common drilling machine operator's need to detect frequently the indirect size of control, labour intensity is large and be difficult to accomplish dimensional uniformity.

Summary of the invention

The technical problem that the utility model solves is to remove the cast gate drilling machine for casting spinning combination process aluminum vehicle wheel provides a kind of technique wheel lip of can automatically directly controlling to the central boss size, to reduce the poor impact on the spinning operation of cast gate process dimension control uniformity, reduce simultaneously drilling machine operator's labour intensity.

The technical solution adopted in the utility model is: a kind of aluminum vehicle wheel removes the cast gate drilling machine, comprises pedestal, jig, brill milling cutter, main shaft.Wheel is placed on the jig, and jig is arranged on the pedestal, and the positioning car wheel shaft is to reaching the central axis position.Drill press spindle arranges the shaft shoulder in terminal.Wheel lip plane feeler arm is installed on the main shaft, and contacts the location with the shaft shoulder, and feeler arm can axially move freely along main shaft.Wheel lip plane trigger sensor is set on the feeler arm, and the trigger sensor trigger point is concordant with special jewel milling cutter apex horizontal face under the normality.

Main shaft drive feeler arm and trigger sensor are to lower feeding during work, when the trigger sensor trigger point touches the foreign steamer lip, feed back to digital control system and bore at this moment the milling cutter position of tool tip, digital control system is bored the milling cutter position of tool tip according to detecting, automatically the wheel end face that increases Tool Design dimension D 1 and will control is to the dimension D 0 of trumpet assembly boss, calculate and bore milling cutter withdrawing position, main shaft feeds downwardly into withdrawing position withdrawing.With regard to dependence equipment itself, directly guaranteed the dimension D 0 of wheel end face to the trumpet assembly boss like this, the error of having avoided the wheel distortion to cause.

The beneficial effects of the utility model are, can rely on equipment and cutter to guarantee that directly technique wheel lip end face has the size of material impact to this a pair of spinning operation of trumpet assembly boss, avoid because the error that indirect detection and manual operation cause, also reduce simultaneously operator's detected intensity, improve working (machining) efficiency.

The specific embodiment

The technical solution adopted in the utility model is: a kind of aluminum vehicle wheel removes the cast gate drilling machine, comprises pedestal 1, jig 2, bores milling cutter 5, main shaft 6.Wheel 3 is arranged on the jig 2, and jig is arranged on the pedestal 1, thereby the positioning car wheel shaft is to reaching the central axis position.Drill press spindle 6 arranges the shaft shoulder 8 in terminal.Wheel lip plane feeler arm 4 is installed on the main shaft, and contact the location with the shaft shoulder, feeler arm 4 can axially move freely along main shaft 6, mounting wheel lip plane trigger sensor 7 on the feeler arm 4, and trigger sensor 7 trigger points are concordant with special jewel milling cutter 5 apex horizontal faces under the normality.

Main shaft 6 carries feeler arm 4 and trigger sensor 7 to lower feeding during work, feed back to digital control system axial location this moment after triggering, namely bore the milling cutter position of tool tip, digital control system is according to the axial location that detects, again automatic torque-increasing add Tool Design dimension D 1 and the wheel end face that will control to the dimension D 0 of trumpet assembly boss, calculate and bore milling cutter withdrawing position (figure two), main shaft feeds downwardly into withdrawing position withdrawing, like this with regard to dependence equipment itself, directly guaranteed the dimension D 0 of wheel end face to the trumpet assembly boss, the error of having avoided the wheel distortion to cause.

Claims

1. an aluminum vehicle wheel removes the cast gate drilling machine, comprise pedestal (1), jig (2), bore milling cutter (5), main shaft (6), it is characterized in that: drill press spindle (6) arranges the shaft shoulder (8) in terminal, wheel lip plane feeler arm (4) is installed on the main shaft (6), and contact the location with the shaft shoulder (8), the upper mounting wheel lip plane trigger sensor (7) of feeler arm (4), trigger sensor (7) trigger point is concordant with brill milling cutter (5) apex horizontal face.
