Abstract
The invention relates to special clamping equipment for drilling five holes in a needle plate support. The special clamping equipment a bottom plate and a drilling bushing bracket, wherein five drilling bushings which are matched with the five drilled holes in the needle plate support in position and diameter are vertically mounted on a horizontal top plate of the drilling bushing bracket. The special clamping equipment is ingenious in design, reasonable in structure, convenient in use, strong in practicality and long in service life. With the adoption of the special clamping equipment, five holes of a workpiece can be machined through once clamping, so that the special clamping equipment has the advantages of high machining accuracy, high machining speed, high efficiency, and the like.
Description
Technical field
The present invention relates to the anchor clamps field, bore five hole exclusive clamps holding equipments above especially a kind of needle plate holder.
Background technology
The top needs of use in sewing machine needle plate holder get out the hole of five φ 3.3, and conventional machining process needs No. five clampings just can machine, and there is long, ineffective shortcoming of clamping time in it.And multiple clamping can increase error, influences machining accuracy.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of reasonable in design, simple in structure, easy to manufacture, bore five hole exclusive clamps holding equipments above the needle plate holder that process velocity is fast, precision is high.
The present invention solves its technical problem and realizes through following technical scheme:
Bore five hole exclusive clamps holding equipments above a kind of needle plate holder; It is characterized in that: comprise a base plate; A drill bushing support is installed on this base plate, five drill bushings that match with five bore positions above the needle plate holder and diameter vertically are installed on the horizontal top of this drill bushing support.
And, installing the screw of a level on the riser of said drill bushing support, the front end of this screw installs a location-plate that is used to locate workpiece, and this location-plate is positioned at the below of drill bushing support level top board.
And, also a pressing plate that is used for workpiece pressing is installed on the riser of said drill bushing support through screw rod.
And, vertically install a backstay that is positioned at the top board below on the horizontal top of said drill bushing support.
Advantage of the present invention and beneficial effect are:
1, this clamping device has been installed five drill bushings that match with bore position and diameter above the needle plate holder on the horizontal top of drill bushing support; Therefore with behind clamping of workpiece; Can accomplish the boring work in five holes, thereby shorten process time, improved operating efficiency.
2,, therefore reduced mismachining tolerance, improved machining accuracy, ensured the quality of product owing to use this to install the processing that a back clamping can be accomplished five processes.
3, this clamping device is that the employing material is the iron plate of 45#; With the special fixture that rocking arm mills, lathes such as line cutting, surface grinding machine are processed, drill bushing employing high quality white steel is processed, so this device has good abrasion resistance through design back; Durable in use, long service life.
4, the present invention bores five hole exclusive clamps holding equipments above a kind of needle plate holder that designs ingenious, rational in infrastructure, easy to use, practical and long service life; Owing to use this device can five holes of workpiece to be processed, so this device has had, and machining accuracy is high, process velocity is fast, the efficient advantages of higher through a clamping.
