Background technology
At present installing hole, locating hole and other pilot holes on the control valve valve body mostly adopts boring machine to process, and do not have Special tooling clamp man-hour adding, process again but directly valve body is fixed on the boring machine,
Its clamping trouble, hand labor intensity is large, and inefficiency can not satisfy the requirement that batch machining is produced.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of inching valve valve body boring jig is provided, solved directly valve body to be fixed on the boring machine and processed again, its clamping trouble, hand labor intensity is large, inefficiency can not satisfy the problems such as requirement that batch machining is produced.
The utility model is achieved through the following technical solutions:
A kind of inching valve valve body boring jig, include clamp body, it is characterized in that: be distributed with installing hole and locating hole on the horizontal plane of described clamp body, and be installed with backing plate by installing hole, described backing plate is provided with the locating hole that cooperates with the locating hole of its below, the pressing plate of described backing plate both sides is fixedly mounted on the horizontal plane of clamp body by studs, the simultaneously supporting of the pressing plate by installing in the clamp body locating hole is supported with the alignment pin of installing in the locating hole on the backing plate, also distributes on the described backing plate to remain the locating hole of bore hole inching valve valve body.
The vertical plane of described clamp body matches with the work top of boring machine, and described backing plate is positioned at the middle part of clamp body horizontal plane.
Described pressing plate supporting is the axis body of TOE, and the other end of described axis body is provided with keyway.
Described clamp body is installed with backing plate by flat head screw in the installing hole, and clamp body is installed with backing plate and treats bore hole inching valve valve body by diamond positioning pin is installed in the installing hole.
Its principle is: at first clamp body is fixed on the boring machine, then will treat that by pressing plate and diamond positioning pin bore hole inching valve valve body fixes, treat in the process that bore hole inching valve valve body supports by pressing plate and cylindrical positioning pins carries out supporting and location, then by studs pressing plate is locked, namely finish behind the location of bore hole inching valve valve body, can carry out bore hole, it is simple to operate, and hand labor intensity is little, and is time saving and energy saving, high efficiency is particularly suitable for the requirement that batch machining is produced.
The utility model has the advantages that:
The utility model reasonable in design is the special fixture of inching valve valve body bore hole, and it is simple to operate, and hand labor intensity is little, and is time saving and energy saving, and high efficiency is particularly suitable for the requirement that batch machining is produced.
The specific embodiment
Referring to accompanying drawing, a kind of inching valve valve body boring jig, include clamp body 1, be distributed with installing hole and locating hole on the horizontal plane of clamp body 1, and be installed with backing plate 2 by installing hole, backing plate 2 is provided with the locating hole that cooperates with the locating hole of its below, the pressing plate 8 of backing plate 2 both sides is fixedly mounted on the horizontal plane of clamp body 1 by studs 3, the simultaneously supporting of the pressing plate by installing in clamp body 1 locating hole 4 is supported with the alignment pin 10 of installing in the locating hole on the backing plate 2, also distributes on the backing plate 2 to remain the locating hole of bore hole inching valve valve body 5; The vertical plane of clamp body 1 matches with the work top of boring machine, and backing plate 2 is positioned at the middle part of clamp body 1 horizontal plane; Pressing plate supporting 4 is the axis body of TOE, and the other end of axis body is provided with keyway 6; Clamp body 1 is installed with backing plate 2 by flat head screw in the installing hole 9, and clamp body 1 is installed with backing plate and treats bore hole inching valve valve body 5 by diamond positioning pin 7 is installed in the installing hole.
