Abstract
The utility model discloses a kind of valve rocker shaft stool fixture, including clamp base, fixture riser, top pressure screw, locating shaft, diamond positioning pin, bushing plate.Renewable bushing, bushing and drill bushing screw are installed, the installation between clamp base, fixture riser and bushing plate is positioned and fastened by straight pin and screw, and locating shaft is fastened on fixture riser by band shoulder hex nut on bushing plate.The utility model is limited the six-freedom degree of workpiece, is realized that it is positioned completely, clipping variation is simple, and reliably, apparatus structure is simple, easy to operate using the positioning method of " plane and two pits ".
Description
Technical field
The utility model belongs to fixture design field, is related to a kind of valve rocker shaft stool fixture.
Background technology
Valve rocker shaft stool is an important part of pneumatic door control system on diesel engine, and a hole is used for assembling on part
Rocker arm shaft.There is the less through hole of a diameter at the hole, at work for oil extraction.But the diameter of the outage is smaller and angle
Tilt, be not easy to process.For the difficulty of the hole work in-process, a kind of machining fixture of valve rocker shaft stool is devised.
The content of the invention
The utility model provides a kind of valve rocker shaft stool folder dedicated for processing outage regarding to the issue above
Tool.
To solve the above-mentioned problems, the technical solution adopted in the utility model is：A kind of valve rocker shaft stool fixture, its
It is characterized in：Fixture riser and top pressure screw are installed in clamp base, bushing plate is installed at the top of fixture riser, is pacified on bushing plate
Equipped with drill bushing and drill bushing screw, fixture riser front is provided with the hole of locating shaft and positioning pin, passes through locating shaft and positioning pin
Relative position can determine that the angle of outage need to be processed.
Clamp base and fixture riser, the assembling of fixture riser and bushing plate are all positioned using straight pin, passed through
Sunk screw is fixed.Bushing is housed between bushing plate and drill bushing, ensures the installation accuracy of drill bushing.Drill bushing screw during work
Drill bushing is compressed, ensures that the position of drill bushing during work is fixed.The top pressure screw installed in clamp base, it is adjusted by thread fitting
Highly, easy to the installation and dismounting of workpiece to be processed, and main cutting force can be born.After the completion of part positioning, by locating shaft
Band shoulder hex nut compressing component, part is fixed in the axial direction.
The beneficial effects of the utility model：
The utility model is limited the six-freedom degree of workpiece, is realized that its is complete using the positioning method of " plane and two pits "
Positioning, compared with prior art, the present apparatus preferably ensure that the positional precision in hole to be processed, and clipping variation is simple, reliably, just
In the installation and removal of workpiece, and apparatus structure is simple, easy to assembly, easy to repair.
Brief description of the drawings
Fig. 1 is the structural front view of the utility model；
Fig. 2 is the structure top view of the utility model；
Fig. 3 is the structure left view of the utility model；
Fig. 4 is the front view of the utility model workpieces processing.
Embodiment
The technical solution of the utility model is made further explanation with specific embodiment below in conjunction with the accompanying drawings.
The utility model includes clamp base 1, and fixture riser 2 is provided with clamp base 1, is leaned between two parts uniformly distributed
Straight pin 13 and sunk screw 12 are positioned and fixed, and are provided with bushing plate 3 on fixture riser 2, between two parts by pair
The straight pin 16 and sunk screw 15 of angle distribution are positioned and fixed.It is provided with fixture riser 2 for positioning work to be processed
The locating shaft 11 and diamond positioning pin 14 of part 4, locating shaft 11 lean on band shoulder hex nut 9 to be anchored on fixture riser 2.Bushing plate 3
It is upper that the renewable bushing 7 playing the guiding role in drilling is housed, and between the two equipped with bushing 8 to ensure the installation accuracy of drill bushing,
Drill bushing screw 8 is installed by drill bushing at the same time, ensures that drill bushing position is fixed during processing.Top pressure support is also equipped with clamp base
3 to bear cutting force.
Locating shaft 11 and diamond positioning pin 14 in this fixture, the two setting elements realize " simultaneously a hole adds a pin "
Positioning method, the six-freedom degree of workpiece can be limited.The axial connecting line of two setting elements is with horizontal angle
The angle of inclination of outage, therefore, as long as ensureing manufacture and the installation accuracy of fixture, can ensure the position of outage processed
Put precision.
After the completion of workpiece positioning, by 9 compressing component of band shoulder hex nut on locating shaft, and increase by one at binding face
Packing ring 10, prevented positioning phenomenon.
Claims (2)
