Abstract
The invention relates to the technical field of machine tool fixtures, in particular to a synchronous hold-down mechanism. The synchronous hold-down mechanism comprises hydraulic cylinders, a base body, racks, gears, gear shafts and pressing plates; the two hydraulic cylinders are arranged side by side and connected through an oil inlet pipe and an oil outlet pipe, and the oil inlet pipe and the oil outlet pipe correspond to the front ends and the rear ends of the hydraulic cylinders respectively; the number of the racks is two, the number of the gears is two, the racks are meshed with the gears, the racks are arranged side by side, the front ends of the racks are correspondingly connected with output shafts of the hydraulic cylinders respectively, and the gears are arranged on the rear portions of the racks and correspondingly meshed with the racks respectively; the hydraulic cylinders, the racks and the gears are covered with the base body, the gears are fixed to the gear shafts, the gear shafts are fixed to the base body, the tail ends of the racks extend out of the base body and are fixedly provided with the pressing plates, a workpiece is pressed through synchronous translational motion, pressing is reliable, and the hydraulic driving operation is easy and saves labor.
Description
Technical field
The present invention relates to jig technical field, be specifically related to synchronous compacting mechanism.
Background technology
When clamping, the fixture of the horizontal-clamping of existing lathe generally cannot ensure that the left and right sides of workpiece is synchronously clamped, for bench vice, bench vice to coordinate with pressing plate with leading screw and clamps screw mandrel and be arranged in the middle part of pressing plate, the translation of rotational lead screw pressing plate is with clamping work pieces, but in the process of clamping, the two ends of pressing plate often occur tilting, make to fit tightly with workpiece when clamping work pieces to make fill not clamping or make clamping workpiece occur being biased, especially after long-time use, this situation is particularly serious, affect the effect of clamping, current most translation fixture adopts this structure mostly, the effect not only clamped is bad, and operation is wasted time and energy.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides synchronous compacting mechanism, in synchronous translation with workpiece pressing, compress reliable, and hydraulic-driven is simple to operate laborsaving.
The technical scheme that the present invention solves the employing of its technical problem is as follows:
Synchronous compacting mechanism, comprise hydraulic cylinder, pedestal, tooth bar, gear, gear shaft and pressing plate, described hydraulic cylinder number is two and is set up in parallel, link with oil inlet pipe and flowline between hydraulic cylinder, oil inlet pipe, the rear and front end being arranged on hydraulic cylinder that flowline is corresponding respectively, described rack and pinion engagement number is two, tooth bar is set up in parallel that its front end is corresponding with hydraulic cylinder output shaft respectively to be linked, gear is arranged on rack rear and correspondingly with tooth bar respectively engages, described pedestal is located at hydraulic cylinder, the outside of rack and pinion, gear is fixed on gear shaft, gear shaft is fixed on pedestal, tooth bar end leans out to pedestal outside and is fixed with described pressing plate.The length of tooth bar is identical, rack and pinion engages, two gears are fixed on synchronous axial system on gear shaft, hydraulic cylinder output shaft exports and makes tooth bar forward or movable, under the effect of synchromesh gear, make two rack synchronous translations and make pressing plate apply equal thrust to workpiece both sides to ensure that workpiece is compacted stably simultaneously, compress effect better.
Further, the oil inlet pipe of described hydraulic cylinder links with flowline and outside oil supply system and is provided with gauge tap, the front and back end of two hydraulic cylinders is equipped with the pipeline of connection, the centre of pipeline is connected with the oil pipe linking fueller with threeway, the stroke of hydraulic oil between oil pipe to two hydraulic cylinders is identical, synchronism is comparatively strong, and impel hydraulic cylinder output shaft synchronous to export, hydraulic-driven is more laborsaving.
Further, described pedestal and tooth bar end relative position place are provided with breach.
Further, the side that the direction of tooth bar teeth is arranged towards gear, and combine closely with gear, preferably, upwards, gear is arranged on tooth bar top to described tooth bar teeth, reduces difficulty during assembling.
Further, described gear shaft and gear synchronous rotate, and gear shaft and pedestal junction are provided with bearing, and synchronous axial system ensure that the synchronous translation of tooth bar, improve the effect compressed.
Further, described pressing plate is vertically arranged, pressing plate is parallel with surface of the work to be compressed reliably to make laminating closely impel, preferably, the number of pressing plate is two and dimensions is identical, does not use overall pressing plate, makes to add at extra bed the leeway stayed man-hour with enough, for cutter provides wider feed path, and the little minimizing foreign matter of the contact surface of pressing plate and workpiece is on the impact compressed.
The invention has the beneficial effects as follows: adopt such scheme, the gear of synchronous axial system impels rack synchronous translation to make the workpiece pressing of briquetting SEQ, and hydraulic-driven is more laborsaving, convenient operation, reduce the amount of labour of operating personnel, impel the raising of production efficiency.
