Abstract
The utility model relates to a special clamping device for drilling two holes on the back face of a needle bracket. The device comprises a base plate; a drill sleeve bracket is mounted on the upper surface of the base plate; and two drill sleeves matched with the positions and the diameter of two drilling holes on the back surface of the needle bracket are vertically mounted on a top plate of the drill sleeve bracket. The special clamping device for drilling the two holes on the back surface of a needle bracket is smart in design, reasonable in structure, convenient to use, strong in practicability, and long is service life; by adopting the device, one time of clamping can complete two process procedures, thereby improving processing precision, shortening processing time and prompting working efficiency by over two times.
Description
Technical field
The utility model relates to the anchor clamps field, and two hole Special clamping devices are bored at especially a kind of needle plate holder back side.
Background technology
The back side of use in sewing machine needle plate holder need to get out the hole of two φ 3.3, and the conventional machining process clamped one time can only bore a hole, and therefore processing two holes just needs clamping twice, thereby causes clamping time length, inefficiency.And clamping can increase error repeatedly, affects machining accuracy, waste product easily occurs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of needle plate holder back side reasonable in design, simple in structure, easy to manufacture, that clamped one time can be finished porous processing to bore two hole Special clamping devices.
The utility model solves its technical problem and is achieved through the following technical solutions:
Two hole Special clamping devices are bored at a kind of needle plate holder back side, it is characterized in that: comprise a base plate, the upper surface of this base plate is installed a drill bushing support, and two drill bushings that match with two bore positions in the needle plate holder back side and diameter vertically are installed on the top board of this drill bushing support.
And, a riser is installed on the described base plate, a set screw that is used for positioning workpieces is installed on this riser.
And, also comprise a pressing plate that is used for workpiece pressing, be shaped with a slotted hole on this pressing plate, this pressing plate is installed on the base plate by screw rod and slotted hole.
And, vertically install a backstay that is positioned at the top board below on the top board of described drill bushing support.
Advantage of the present utility model and beneficial effect are:
1, this clamping device has been installed two drill bushings corresponding with needle plate holder back drill position and diameter at the top board of drill bushing support, therefore with behind the workpiece clamped one time, can finish the boring work in two holes, thus greatly shortened clamping workpiece time, improved operating efficiency.
2, since after using this device clamped one time can finish the processing of two procedures, so error of having avoided repeatedly clamping to bring has improved machining accuracy, each dimensional accuracy of the part after the processing has all reached requirement, has ensured the qualification rate of product.
3, this clamping device is that to adopt material be the iron plate of 45#, after design with the special fixture that rocking arm mills, the lathes such as line cutting, surface grinding machine are made, the service life that it has good anti-wear performance and extremely grows.
4, the utility model is that two hole Special clamping devices are bored at a kind of needle plate holder back side of designing ingenious, rational in infrastructure, easy to use, practical and long service life, therefore use this device clamped one time can machine two procedures, improved machining accuracy, shortened process time, operating efficiency has improved more than the twice.
