Abstract
The utility model relates to a fine-tuning and positioning mechanism for a hydraulic press slide block. The utility model is characterized in that four worm gear transmission boxes are uniformly distributed on an upper beam of a hydraulic press; the four worm gear transmission boxes are connected with three speed reducers and frequency variable motors which are one to one by four transmission shafts to make the four worm gear transmission boxes to synchronously rotate; screw threads and a hollow screw rod moving up and down are arranged in center holes of worm gears of the four worm gear transmission boxes; the upper end surface of the hollow screw rod is a positioning surface, a limiting draw rod of which the lower end is fixed on a slide block is arranged in the hollow screw rod and the upper end of the limiting draw rod has a limiting surface. The travel range of the slide block is adjusted by the relative distance of the positioning surface of the hollow screw rod and the plane of the upper beam, the problems of inaccurate travel range and inconvenience of an adjusting block of an original hydraulic press, and the work efficiency is improved; in addition, the utility model also has the advantage of simple and reliable operation.
Description
Technical field
The utility model relates to a kind of hydraulic press that is used for forging industry, especially a kind of slider of hydraulic press fine setting detent mechanism.
Background technology
Hydraulic press is widely used in processing stretching, the trimming of various large-scale coverings.Its operating process is: at first upper and lower mould is installed on the workbench and slide block of hydraulic press the gap about adjusting then between the mould and the stroke of slide block respectively.The stroke of slide block is too small, and upper and lower mould matched moulds is incomplete; Ram travel is excessive.Can mold damage.Therefore the ram travel adjustment is the operation of outbalance in the hydraulic press.The method of the ram travel of the installation mold of hydraulic press adjustment at present mainly is to determine the stroke of slide block by the crawl of hydraulic press switch and operator's experience.This method both inaccuracy is also inconvenient, also often causes the damage of die surface.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of adjustment ram travel accurately, the detent mechanism of slider of hydraulic press fine setting easily.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of slider of hydraulic press fine setting detent mechanism, by uniform four worm boxes that are installed in the top beam of hydraulic machine both sides, the power transmission shaft that connects between two worm box worm screws of each side, be installed in the middle reductor that has two output shafts of entablature and drive variable-frequency motor, and the reductor of the transferring power that also is connected respectively between the end worm screw of reductor two output shafts and both sides worm box and power transmission shaft are formed, it is characterized in that: be shaped on screw thread in the worm gear centre bore in described four worm boxes and rectilinear motion up and down is installed and in have the hollow leading screw of locating surface, the lower end is installed in the hollow leading screw is fixed on the pull bar that upper end on the slide block has the stroke limit face; One of them worm screw of described worm box also connects the rotary encoder that has digital display device.
The utility model can also adopt following technical measures:
The upper surface of described four worm boxes and entablature lower surface all are equipped with the tubular dust cover of protection stroke limit pull bar and hollow leading screw.
Advantage and the good effect that the utlity model has are: since on entablature four worm boxes of uniform installation and drive the variable-frequency motor that four worm boxes rotate synchronously, reductor and power transmission shaft, in the worm gear centre bore of each worm box, be shaped on screw thread and the hollow leading screw that moves up and down is installed, the lower end is installed in each hollow leading screw is fixed on stroke limit pull bar on the slide block, adjust locating surface and the relative distance on entablature plane and the digital display device of worm box of hollow leading screw by the control worm box, reach the stroke of control slide block, not only accurately but also convenient, improved operating efficiency greatly, the utility model also has easy and simple to handle in addition, reliable advantage.

Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is an I enlarged drawing among Fig. 2.
Among the figure: 1 digital display device and rotary encoder, 2 worm boxes, the 2-1 worm screw, the 2-2 worm gear, 3 power transmission shafts, 4 worm boxes, the 4-1 worm screw, the 4-2 worm gear, 5 reductors, 6 power transmission shafts, 7 reductors, 8 variable-frequency motors, 9 power transmission shafts, 10 reductors, 11 worm boxes, the 11-1 worm screw, the 11-2 worm gear, 12 power transmission shafts, 13 worm boxes, the 13-1 worm screw, the 13-2 worm gear, 14 entablatures, 15 hollow leading screws, 16 pull bars, 17 confined planes, 18 dust covers, 19 dust covers, 20 nuts, 21 nuts, 22 locating surfaces, 23 slide blocks.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, uniform four worm boxes 2,4,11,13 that are equipped with on top beam of hydraulic machine 14.For four worm boxes are rotated synchronously, be connected with power transmission shaft 3 between the worm screw 2-1 of worm box 2 and the worm screw 4-1 of worm box 4; Also be connected with power transmission shaft 12 between the worm screw 11-1 of worm box 11 and the worm screw 13-1 of worm box 13.Rotate in order to drive four worm boxes, be separately installed with 1: 1 reductor 5,10 at the worm screw 11-1 other end of the worm screw 4-1 of worm box 4 other end, worm box 11,1: 1 reductor, 7, the two output shaft reductor inputs that the input of two reductors is connected with two output shafts by power transmission shaft 6,9 respectively are equipped with and drive variable-frequency motor 8.As shown in Figures 2 and 3, worm gear 2-2 at four worm boxes, 4-2,11-2, all be shaped on screw thread in the 13-2 centre bore and the hollow leading screw 15 that can move up and down is installed, locating surface 22 is arranged in the hollow leading screw, be movably installed with the lower end in the hollow leading screw and be fixed on stroke limit pull bar 16 on the slide block 23, the bottom of pull bar is by two nuts 20,21 fix with slide block, the upper end of pull bar is shaped on confined planes 17, just can reach the distance of adjusting slide block down by locating surface and the relative distance between the entablature plane of adjusting hollow leading screw like this, the other end at worm screw 2-1 also is equipped with digital display device and the rotary encoder 1 of adjusting ram travel, is easier to understand the stroke of slide block like this.In order to prevent that pull bar top and leading screw lower end are subjected to the dust in place or the wearing and tearing of impurity to be separately installed with dust cover 18 and 19 on the entablature of on four worm boxes and four leading screw lower ends.
