Background technology
The plate-like class part such as flange, end cap is common part in machining industry, flange, end cover part shape and specification
Varied, material is mostly steel part or casting class.Such part is mostly exposed part, it is desirable to good appearance, while require use when
With interchangeability, that is, require that the bolt hole position of each part is accurate.This some holes need to be processed with common vertical type rocker arm drilling machine, due to
Each part shape different sizes, and batch is less, so positioning, the folder of most of part can be competent at without unified boring grab
Tight work.
Traditional hole forming method is：Turning blank shaping-platform centering-line-dotting punch-drilling machine clamping-is right
Knife-drilling, this method is adapted to single hole processing, low production efficiency, and has to pass through crossed process before drilling.Due to plate-like class
Part has centre bore, bad alignment point, therefore work of ruling is considerably complicated, if number of parts is few and needs renewal part,
Then need frequently line, change fixture etc., greatly reduce production efficiency.In the process in hole, operator's eyesight pair is depended alone
Knife, error is larger, easily causes indexing inaccurately, can not exchange.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of boring grab, its simple in construction, simple operation, energy

Life length.
The purpose of this utility model is achieved through the following technical solutions：
A kind of boring grab, including the base being arranged on working plate, ladder hole is offered at the base center,
Index dial is installed, the top of the index dial is arranged on above base, and the indexing tray bottom passes through in the ladder hole
Cylinder roller bearing is rotatably installed on working plate, and index dial top bottom surface sets a circle thrust ball bearing, the index dial
Scroll chuck is fixedly arranged above, the scroll chuck upper end clamps and is placed with processing part；Also laterally set on the working plate
Alignment pin is equipped with, the alignment pin is arranged on location key seat, and the rear end of the alignment pin is provided with fixed thimble and compression spring,
The rear end lower of the fixed thimble is provided with operation handle, the side that the front end of the operation handle passes through bearing pin and location key seat
Face is rotatablely connected.
Further, the upper outside of the index dial is provided with a circle neck, and the neck sets up separately along index dial surrounding etc.
Put.
Preferably, the index dial is rotatably installed on the table top in ladder hole by thrust ball bearing.
Preferably, the scroll chuck includes chuck and three clamping jaws on chuck, and the chuck is open circles
Cylinder, three clamping jaws, which clamp, to be arranged on the outboard sidewalls of chuck.
Compared with prior art, the utility model at least has advantages below：
By above-mentioned the technical solution of the utility model, processing part is fixed using scroll chuck, by alignment pin insertion point
In scale neck, central hole location during Drilling operation is ensure that, after a side opening is processed as, operation handle pushes, fixed
Thimble is shunk, and alignment pin is returned in location key seat, is rotated index dial conversion processing part orientation, is made positioning using contraction spring
For pin again insertable into index dial neck, so circulation is drilled the hole required by part, when the utility model ensure that Drilling operation,
The centre bore of part is processed, without frequent handling part, indexing accuracy is high, can quickly load and unload part, indexing is easily, soon
It is fast, convenient, the decile of drilling part is improved, and manufacturing cost is low, service life length.
