Description
Technical Field
The utility model relates to an universal tester makes the field, especially relates to a double-cylinder synchronizing mechanism.
Background
In the prior art, a double-oil-cylinder technology is adopted to provide power for the pulling and pressing actions of the universal machine, two pistons of the double-oil-cylinder are respectively fixed with two ends of an upper jaw seat, and the upper jaw seat is lifted through synchronous stretching of the two pistons.
However, the technique has the following defects: the high-precision synchronization of the movement of the pistons of the two oil cylinders is difficult to achieve, so that the movement speeds of the two ends of the upper jaw seat are different, and the pull-press test result of the universal machine is influenced.
Based on this, the present disclosure is thus directed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a two hydro-cylinders lazytongs guarantees the motion synchronism of two pistons of two hydro-cylinders.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
the utility model provides a double-cylinder synchronizing mechanism, includes the frame of compriseing entablature, stand, base, is fixed with lower jaw seat on the stand, and the below of lower jaw seat is fixed with double-cylinder, the piston end of hydro-cylinder is fixed with the upper jaw seat relative with lower jaw seat, includes two lead screws, and the lower extreme of two lead screws is connected at the both ends of lower jaw seat through the bearing respectively, and even there is the synchronizing wheel after the upper end passes upper jaw seat, entablature in proper order, even there is the hold-in range between two synchronizing wheels, lead screw and upper jaw seat pass through threaded connection, and pass through bearing connection between the entablature.
The utility model has the advantages that: the motion difference caused by double oil cylinders is eliminated by adopting the screw rod, the synchronous belt and the synchronous wheel, the motion synchronism of the two ends of the upper jaw seat is ensured, and an effective technology is provided for the high-precision tension-compression test of the universal machine.

description of the reference symbols
The device comprises an upper cross beam 1, a stand column 2, a base 3, a lower jaw seat 4, an upper jaw seat 5, an oil cylinder 6, a piston 7, a screw rod 8, a synchronous wheel 9 and a synchronous belt 10.
Detailed Description
The present invention will be described in further detail with reference to examples.
As shown in fig. 1, the present embodiment provides a double-cylinder 6 synchronization mechanism, which includes a frame composed of an upper beam 1, a column 2, and a base 3, wherein a lower jaw seat 4 is fixed on the column 2, a double-cylinder 6 is fixed below the lower jaw seat 4, and an upper jaw seat 5 opposite to the lower jaw seat 4 is fixed at a piston 7 end of the cylinder 6. The synchronous mechanism further comprises two lead screws 8, the lower ends of the two lead screws 8 are connected to the left end and the right end of the lower jaw seat 4 through bearings respectively, the upper ends of the two lead screws sequentially penetrate through the upper jaw seat 5 and the upper cross beam 1 and then are connected with synchronous wheels 9, a synchronous belt 10 is connected between the two synchronous wheels 9, and the lead screws 8 are connected with the upper jaw seat 5 through threads and connected with the upper cross beam 1 through bearings.
When the pressure test is carried out, for example, the upper jaw base 5 moves downwards under the action of the oil cylinders 6, the screw rod 8 is connected with the upper jaw base 5 through threads, the screw rod is inevitably driven to rotate in the downward movement process of the upper jaw base 5, the synchronous wheel 9 on the screw rod is driven to move by the rotation of the screw rod, if the moving speeds of the pistons 7 of the two oil cylinders 6 are the same, the moving speeds of the two screw rods are the same, if the moving speeds of the pistons 7 of the two oil cylinders 6 are different, the moving speeds of the two screw rods are mutually adjusted through the synchronous wheel 9 and the synchronous belt 10, and finally the movement speeds are consistent, so that the movement of the two ends of the upper jaw base 5 is synchronous.
The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
