Abstract
The utility model discloses electric hydraulic precision flat-nosed pliers which mainly comprise an electric pumping plant, precision flat-nosed pliers, a hydraulic oil pipe, a movable plier jaw, a fixed plier jaw, a base, a hydrocylinder and the like. The hydrocylinder is fixed on an oil cylinder support; a plunger piston of the hydrocylinder is fixedly connected with the movable plier jaw; and the electric pumping plant is connected with the hydrocylinder through the hydraulic oil pipe. When the flat-nosed pliers is in operation, the electric pumping plant is switched on for oil supply; the plunger piston at the front end of the oil cylinder drives the movable plier jaw to move quickly and slightly so as to clamp a workpiece; and the workpiece is loosened through a transfer handle of the electric pumping plant. The utility model has the advantages of reasonable structure, high precision, simple operation, durability, reduction of labor intensity, and improvement of work efficiency, and can be widely applied to the workbenches of a computerized numerical control machining center and various common machine tools.
Description
Technical field
The utility model relates to a kind of machine tool accessories, refers more particularly to a kind of electric hydaulic precision flatnosed pliers.
Background technology
Precision flatnosed pliers is a kind of machine tool accessories, uses usually on the workbench of lathes such as milling machine, drilling machine, shaping machine and surface grinding machine.Precision flatnosed pliers is generally by vice body, regular jaw and moving jaw, and the transmission mechanism that moving jaw is moved is formed, the described transmission mechanism that moving jaw is moved, the lead screw transmission that is generally at present commonly used, promptly by the spanner rotating threaded shaft, leading screw moves forward along screw thread, pushes moving jaw to regular jaw, reaches the purpose of clamping work pieces.Use this precision flatnosed pliers in machine operation, operating handle is pushing, and the leading screw pace is slow, and service efficiency is low, the operation effort, and skilled worker's labour intensity is big.And in the decreased food scope of design, can not reach the required chucking power requirement of workpiece, the gimmick of using boosting-rod or hammering control crank of not stinting solves, and often brings worry in the use to the operator, and has a strong impact on machining efficient.A spot of electronic or pneumatic type flat-nose pliers is also arranged at present, the instability of pneumatic type wherein, pressure is little; Little, the lasting pressure differential of DYN dynamic pressure.Therefore pneumatic type, DYN dynamic the popularization are come.
Summary of the invention
Provide a kind of electric hydaulic precision flatnosed pliers for addressing the above problem the utility model, utilized the combination of electric pump station and precision flatnosed pliers, the labour intensity when having effectively reduced operation has improved operating efficiency.
The utility model is achieved through the following technical solutions.A kind of electric hydaulic precision flatnosed pliers: mainly by electric pump station, precision flatnosed pliers, hydraulic oil pipe, compositions such as moving jaw, regular jaw, caliper, hydraulic jack, hydraulic jack is fixed on the cylinder support, cylinder support can move around on the guide rail of caliper, and can be fixed by positioning device on base, the plunger of hydraulic jack is fixedlyed connected with moving jaw, and electric pump station connects hydraulic jack by hydraulic oil pipe.During operation, according to the workpiece size, the position of rapid adjustment cylinder support, and fixed oil cylinder bearing, open the electric pump station fuel feeding, end plug drives the quick minute movement of moving jaw, clamping work pieces before the oil cylinder, electric pump station was closed automatically after oil pressure reached setting pressure, unclamped workpiece by the change lever of electric pump station.
The utility model electric hydaulic precision flatnosed pliers and in the past precision flatnosed pliers compare and have following characteristics: provide power by electric pump station, clamping great efforts and can arbitrarily adjusting, constant and the compensatory pressure at any time of dynamics, the workman only need control electric pump station and operate, reduced labour intensity, improved operating efficiency simultaneously, the utility model is rational in infrastructure, the precision height has advantages of high practicability.
Description of drawings
Below in conjunction with accompanying drawing the utility model hydraulic pressure precision flatnosed pliers is further described.
Fig. 1 is the overall structure schematic diagram of the utility model hydraulic pressure precision flatnosed pliers.
Fig. 2 is the precision flatnosed pliers structure chart.
Fig. 3 is the structural representation of the utility model hydraulic pressure precision flatnosed pliers cylinder bracket.
Among the figure, 1, electric pump station, 2, hydraulic oil pipe, 3, oil connection, 4, precision flatnosed pliers, 5, hydraulic jack, 6, cylinder support, 7, plunger, 8, moving jaw, 9, caliper, 10, regular jaw, 11, steel ball.
The specific embodiment
Referring to accompanying drawing 1,2, a kind of electric hydaulic precision flatnosed pliers, mainly by electric pump station (1), precision flatnosed pliers (4), hydraulic oil pipe compositions such as (2), precision flatnosed pliers (4) is mainly by moving jaw (8), caliper (9), regular jaw (10), hydraulic jack (5), cylinder support compositions such as (6), hydraulic jack (5) is fixed on the cylinder support (6), cylinder support (6) can move around along the guide rail of caliper (9), the plunger (7) of hydraulic jack (5) is fixedlyed connected with moving jaw (8), electric pump station (1) is by hydraulic oil pipe (2), oil connections (3) etc. connect hydraulic jack (5), and regular jaw (10) is fixed on the caliper (9).Described moving jaw (8) structure was with flat-nose pliers moving jaw structure was consistent in the past, and its bottom forms moving sets with caliper (9); Same and caliper (9) the formation moving sets of described cylinder support (6).
Referring to accompanying drawing 2,3, cylinder support (6) is different with leading screw seat structure in the flat-nose pliers in the past, the position of top rotating threaded shaft is the hydraulic jack (5) in the utility model fixedly, the bottom is established a shrinkage pool equally, be used for placing steel ball (11), caliper track lower surface is provided with some alveoles recessed down, and the both sides of cylinder support (6) are provided with the jackscrew of oblique cutting, two jackscrews can be pressed into steel ball (11) in the alveole of caliper (9) track lower surface, play the purpose of fixed oil cylinder bearing (6).
During operation, according to the workpiece size, the position of rapid adjustment cylinder support (6), suitable back turns the jackscrew of cylinder support (6) both sides with spanner, behind the fixed oil cylinder bearing (6), open electric pump station (1) to hydraulic jack (5) fuel feeding, it is small in the mobile clamping work pieces of regular jaw (10) fast that the preceding end plug of hydraulic jack (5) (7) drives moving jaw (8), oil pressure reaches electric pump station (1) automatic fuel cutoff after the setting pressure, process electric pump station self-compensating pressure can unclamp workpiece by the change lever of electric hydraulic station.
In sum, this use novel hydraulic precision flatnosed pliers is rational in infrastructure, and the precision height is simple to operate, and durable has reduced labour intensity, has improved operating efficiency, can be widely used on the workbench of lathes such as numerical control machining center and various machine tools.
