Abstract
The invention relates to special clamping equipment for drilling two holes on a shaft connecting rod. The special clamping equipment comprises a bottom plate, wherein a vertical plate is vertically arranged on the bottom plate; a horizontal drill bushing support is arranged on the upper end surface of the vertical plate; and two drill bushings matched with the drill holes of the shaft connecting rod in diameter and position are vertically arranged on the drill bushing support. The special clamping equipment has a reasonable structure and long service life, is ingenious in design and high in practicability, and is convenient to use; and by virtue of the device, the two holes of the shaft connecting rod can be processed by clamping for one time, so that the device has the advantages of high processing precision, high processing speed, high working efficiency and the like.
Description
Technical field
The present invention relates to the anchor clamps field, especially a kind of connecting rod bores two hole exclusive clamps holding equipments.
Background technology
The top needs of use in sewing machine axle connecting rod get out the hole of two φ 3, and conventional machining process needs twice clamping just can machine, and there is long, ineffective shortcoming of clamping time in it.And multiple clamping can increase error, causes each dimensional accuracy to be difficult to guarantee.
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, the axle connecting rod that process velocity is fast, precision is high bores two hole exclusive clamps holding equipments.
The present invention solves its technical problem and realizes through following technical scheme:
A kind of connecting rod bores two hole exclusive clamps holding equipments; It is characterized in that: comprise a base plate; A riser vertically is installed on this base plate, and the drill bushing support of a level is installed in the upper surface of this riser, vertically install on this drill bushing support two with the bore position of a connecting rod and the drill bushing that diameter matches.
A backstay that is used for plug-in mounting axle connecting rod is installed in the positive top, left side of riser.
The positive top, middle part of riser is installed one and is used to hold an alignment pin of connecting rod bottom surface.
A pressing plate that is used for workpiece pressing is installed through screw rod in the positive right side of riser, is shaped on slotted hole on this pressing plate, and screw rod passes this slotted hole and is installed on the riser, and the right side of pressing plate is shaped on a stopper slot, makes a limited post that is inserted in this stopper slot on the riser.
Advantage of the present invention and beneficial effect are:
1, this clamping device has been installed two drill bushings that match with axle connecting rod bore position and diameter on the drill bushing support, therefore with behind clamping of workpiece, can accomplish the work of boring two holes, thereby shorten process time, has improved more than the operating efficiency twice.
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 two procedures.
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; It is durable in use, long service life.
4, the present invention is that a kind of axle connecting rod that designs ingenious, rational in infrastructure, easy to use, practical and long service life bores two hole exclusive clamps holding equipments; Owing to use this device can two holes of workpiece to be processed through a clamping, so this device has advantages such as machining accuracy height, process velocity are fast, operating efficiency height.
