Abstract
A hydraulic micro-motion structure comprises a hydraulic machine body, a working table and a sliding block, wherein the working table is located on the hydraulic machine body, the sliding block is controlled by a hydraulic device and provided with a lead screw nut micro-motion device which is driven by a stepping motor, a nut is fixed on the sliding block, and a lead screw is connected with the stepping motor through a transmission shaft. According to the hydraulic micro-motion structure, the sliding block is controlled by the hydraulic device and provided with the lead screw nut micro-motion device which is driven by the stepping motor so as to control the motion of the sliding block, location precision of the sliding block is increased, the hydraulic micro-motion structure is convenient and fast to use, and the motion is finished continuously. Instability of hydraulic control is reduced, a damage rate of die accessories is reduced, and efficiency is improved.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, especially a kind of hydraulic press micromotion mechanism.
Background technology
The general positioning accuracy of in the market hydraulic press fine motion function is poor, does not reach service precision.Hydraulic press fine motion distance does not reach the distance of mould bedding-in requirement on the market, thus need to be before the upper and lower mould closure in the bedding-in process shimming, then 0.05-0.10mm removes successively pad and carries out carved mouth or to drift, affect operating efficiency; In use cause easily the damage of the mould accessories such as cutting edge and drift.
The utility model content
It is high that the utility model technical issues that need to address provide a kind of positioning accuracy, do not damage the hydraulic press micromotion mechanism of drift and mould.
For addressing the above problem, technical solution adopted in the utility model is: a kind of hydraulic press micromotion mechanism, comprise hydraulic press body, the slide block that is positioned at the workbench on the hydraulic press body and is controlled by hydraulic means, be provided with stepper motor driven feed screw nut's inching gear at slide block, wherein nut is fixed on the slide block, and screw mandrel connects motor by power transmission shaft.
This novel improvement is that described feed screw nut's inching gear comprises that also decelerator, reducer input shaft connect motor, output shaft connection for transmission axle.
Stepper motor driven feed screw nut's inching gear and cushion dashpot were 2 covers during this was novel, were arranged on the center, two ends of slide block.
The beneficial effect that adopts technique scheme to produce is: basis is novel controls the in-position of slide block by motor-driven feed screw nut's inching gear is set at slide block, and the slide block positioning accuracy is increased, convenient to use, and action is finished continuously.Reduce the unstability of hydraulic control, reduce the spoilage of mould accessory, raise the efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, decelerator, 2, nut, 3, slide block, 4, power transmission shaft, 5, screw mandrel, 6, cushion dashpot, 7, mould, 8, workbench, 9, hydraulic press body, 10, motor.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail: as shown in Figure 1, the utility model is the machine for mould 7 bedding-ins, this novel hydraulic press body 9 that comprises, the slide block 3 that is positioned at the workbench 8 on the hydraulic press body 9 and is controlled by hydraulic means, wherein be provided with feed screw nut's inching gear driven by stepper motors at slide block 3, this device is by the nut 2 that is fixed on the slide block 3, screw mandrel 5, power transmission shaft 4, motor 10, decelerator 1 forms, screw mandrel 5 is fixed on the power transmission shaft, by the output shaft of power transmission shaft 4 connection reducers, the power shaft of decelerator connects motor 10.
In order to make the hydraulic press positioning accuracy higher, utilize the cushion dashpot 6 on the hydraulic press body to position. the cushion dashpot position is corresponding with the screw mandrel position of feed screw nut's inching gear.In order to make the slide block even running, stepper motor driven feed screw nut's inching gear and cushion dashpot were 2 covers during this was novel, were arranged on the center, two ends of slide block.
Operation principle
When this novel selection micromotion, press inching button, the motor-driven screw mandrel is automatically brought to and sets the position, then directly run to the position that needs of setting with the HYDRAULIC CONTROL SYSTEM slide block, the positioning screw rod end face contacts with cushion dashpot end face gapless, and the minimum range that the utility model can be controlled the slide block operation is 0.04mm.As: need slide block to move 0.04mm downwards, can be by the lower limit inching button, control system provides the driving signal, slide block passes through the up slight distance by HYDRAULIC CONTROL SYSTEM elder generation, make positioning screw rod end face and cushion dashpot end face that minim gap be arranged, positioning screw rod drives screw mandrel by servomotor and rotates, and making the screw mandrel Top Runby is 0.04mm, and slide block down to spacing place is desired location.The Bottom Runby of slide block can set in advance (〉=0.04mm).
The welcome adjustment operating distance of the utility model, and automatically move to the needed position of work, reduced greatly the carved mouth time, improved operating efficiency, reduced production cost.
