Abstract
The invention relates to the technical field of machine tool clamps, in particular to a gear transmission swinging pressing mechanism. The gear transmission swinging pressing mechanism comprises a fixing plate, a hydraulic cylinder, a pressing plate and a gear. The fixing plate is provided with a vertical stand plate, the front end of the pressing plate is in a linear shape, and the back end of the pressing plate is in an arc shape bent downwards. The gear is fixed to the arc back end of the pressing plate and controls the pressing plate to rotate synchronously. The arc back end of the pressing plate is hinged to the stand plate. A rack meshed with the gear is arranged on the part, corresponding to the bottom of the gear, of the fixing plate and connected with the fixing plate in a sliding mode. The hydraulic cylinder is arranged on the back side of the rack. A piston rod of the hydraulic cylinder is connected with the back end of the rack and controls the forward and backward movement of the rack, clamping is quick, labor is saved, pressing is reliable due to hydraulic driving pressing, and the clamp is simple in structure and low in cost.
Description
Technical field
The present invention relates to jig technical field, be specifically related to gear-driven swing hold-down mechanism.
Background technology
Existing jig is varied, workpiece is fixed on platen face and generally positions compression for main to workpiece with pressing plate class fixture, clamping workpiece needs manually adjustment, wastes time and energy, especially, in large batch of processing, the raising of production efficiency is unfavorable for.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides gear-driven swing hold-down mechanism, clamping operation fast power-saving, and hydraulic-driven compresses, and compresses reliable, and the structure of fixture is simple, and cost is low.
The technical scheme that the present invention solves the employing of its technical problem is as follows:
Gear-driven swing hold-down mechanism, comprise fixed head, hydraulic cylinder, pressing plate and gear, described fixed head is provided with vertical riser, described pressing plate front end is linear pattern, rear end is reclinate arc, described gear is fixed on the arc rear end of pressing plate, gear controls pressing plate synchronous axial system, pressing plate arc rear end and riser hinged, fixed head corresponding bottom described gear is provided with the tooth bar with gears meshing, and described tooth bar and fixed head are slidably connected, and described hydraulic cylinder is arranged on rear side of tooth bar, piston rod and the tooth bar rear end of hydraulic cylinder link, and control tooth bar and seesaw.Hydraulic cylinder piston rod travels forward and controls tooth bar reach, and tooth bar reach makes gear rotate counterclockwise, and the gear rotated counterclockwise impels pressing plate front end to press down, and by Work-sheet pressing on the work top of lathe, the power that hydraulic cylinder exports is large, compresses reliable.
Further, described pressing plate front end is provided with downward protruding briquetting, and protruding briquetting surface is provided with anti-skidding lines, and with projection briquetting and absorption surface, contact point is little, and the unit pressure of applying is large, impels the more reliable of compression.
Further, described gear is arranged on hinged place that is corresponding on pressing plate and riser, and gear axis and axle center, hinged place conllinear, impel gear to control pressing plate synchronous axial system.
Further, the external oil supply system of described hydraulic cylinder be provided with gauge tap.
The invention has the beneficial effects as follows: adopt such scheme, do not need manual adjustment when workpiece pressing, also do not need manual compression, hydraulic-driven is more laborsaving, tooth bar meshing gear, gear synchronous pressing plate compresses, and structure is simple, compresses reliable.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
