Description
Technical field
The present invention relates to automobile fixture field, specifically a kind of brill pump housing leaking hole fixture.
Background technology
As everyone knows, due to the direction, aperture of the leaking hole of pump body and pump housing lateral wall and out of plumb but at an angle, be difficult to process it, its two leaking holes are about median plane symmetry in addition, have therefore been difficult to a kind of method or fixture and have been fixed processing.
Summary of the invention
For solving the problem, the invention discloses a kind of clamping adjustable, clamp fastening, effectively two of pump body leaking holes can be carried out the brill pump housing two leaking hole fixtures of Drilling operation, namely a kind ofly bore pump housing leaking hole fixture.
A kind of brill pump housing leaking hole fixture, comprise clamp body, top, described clamp body right side, bottom, right side is provided with backing plate, clamp body centre position is connected with mandrel lower end, be connected with index dial by lining in the middle part of described mandrel, mandrel top is provided with drill jig sleeve, described index dial left surface contacts with backing plate, described index dial is provided with support, the front end face lower end of described clamp body, rear end face lower end is respectively provided with guide pin bushing, index pin is provided with in described guide pin bushing, described guide pin bushing is connected by spring with between index pin, described index pin upper end by lining respectively with clamp body, index dial is connected, index pin lower end is connected with tack handle.Tack handle, by pulling index pin to be moved to the left and Compress Spring, makes index pin right end position and index dial depart from, and just rotatable scale drives the pump housing, carries out second leaking hole processing.
The axes normal of described drill jig sleeve is in the upper surface of clamp body.
Described guide pin bushing inside comprises large shaft sleeve and little axle sleeve, and described index pin comprises large end axle and small end axle.Namely large end axle matches with large shaft sleeve, and small end axle matches with little axle sleeve.
Described large end shaft diameter is greater than little sleeve diameter, and described small end shaft diameter is less than little sleeve diameter, and described spring left end is connected on large shaft sleeve and little axle sleeve interface sidewall, and spring right-hand member is connected on large end axle left side wall.When this mode ensure that and pulls tack handle left, spring is necessarily held greatly axle and is contracted at large shaft sleeve and little axle sleeve interface side wall pressure, and when unclamping tack handle, spring reduces under restoring force effect.
The invention has the beneficial effects as follows:
The present invention has taken into full account the bore angle problem of leaking hole, adopt this clamping adjustable, clamp fastening mode clamping carried out to the pump housing, and the processing of two leaking holes can be completed under a bushing plate, save material, it also avoid the installation position error brought when changing fixture, to guarantee the precision of processing.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As shown in Figures 1 to 6, a kind of brill pump housing leaking hole fixture, comprise clamp body 1, top, described clamp body 1 right side, bottom, right side is provided with backing plate 3, clamp body 1 centre position is connected with mandrel 2 lower end, be connected with index dial 4 by lining 5 in the middle part of described mandrel 2, mandrel 2 top is provided with drill jig sleeve 7, described index dial 4 left surface contacts with backing plate 3, described index dial 4 is provided with support 6, the front end face lower end of described clamp body 1, rear end face lower end is respectively provided with guide pin bushing 9, index pin 10 is provided with in described guide pin bushing 9, described guide pin bushing 9 is connected by spring 11 with between index pin 10, described index pin 10 upper end by lining 5 respectively with clamp body 1, index dial 4 is connected, index pin 10 lower end is connected with tack handle 8.Tack handle 8, by pulling index pin 10 to be moved to the left and Compress Spring 11, makes index pin 10 right end position and index dial 4 depart from, and just rotatable scale 4 drives the pump housing, carries out second leaking hole processing.
The axes normal of described drill jig sleeve 7 is in the upper surface of clamp body 1.
Described guide pin bushing 9 inside comprises large shaft sleeve 9a and little axle sleeve 9b, and described index pin 10 comprises large end axle 10a and small end axle 10b.Namely large end axle 10a matches with large shaft sleeve 9a, and small end axle 10b matches with little axle sleeve 9b.Described large end axle 10a diameter is greater than little axle sleeve 9b diameter, and described small end axle 10b diameter is less than little axle sleeve 9b diameter, and described spring 11 left end is connected on large shaft sleeve 9a and little axle sleeve 9b interface sidewall, and spring 11 right-hand member is connected on large end axle 10a left side wall.When this mode ensure that and pulls tack handle 8 left, spring 11 is necessarily held greatly axle 10a and is contracted at large shaft sleeve 9a and little axle sleeve 9b interface side wall pressure, and when unclamping tack handle 8, spring 11 reduces under restoring force effect.
