Abstract
The utility model relates to a pressing device for a machine tool. The pressing device comprises a machine frame. The machine frame is provided with a vertical guide hole and fixedly provided with a hydraulic cylinder, a piston rod of the hydraulic cylinder is vertically connected with a guide rod downwards, the guide rod penetrates through the guide hole in a sliding mode and extends out of the guide hole, and a pressing plate arranged horizontally is hinged to the bottom end of the guide rod. Two centres are arranged under the pressing plate, and a limiting plate close to the pressing plate is arranged above the pressing plate and fixedly arranged on the guide rod in a sleeved mode. A vertical auxiliary rod is fixedly connected to the upper portion, beside the guide rod, of the pressing plate and penetrates through the machine frame in a sliding mode, and the top end of the auxiliary rod is contained by a spring sleeve. The machine frame is fixedly connected with a horizontal installation plate, the spring sleeve is installed under the installation plate in an upside-down mode, and a spring is arranged inside the spring sleeve. According to the structure, operation of the pressing device for the machine tool is reliable, the piston rod of the hydraulic cylinder drives the guide rod to slide to drive the pressing plate to move downwards, the auxiliary rod slides down smoothly under the elastic force effect of the spring, the efficiency is high, and the requirement of automatic production is met.
Description
Technical field
The utility model relates to a kind of hold down gag of lathe, relates in particular on a kind of lathe in order to press the hold down gag of workpiece.
Background technology
In prior art, when workpiece need to be on being installed to lathe in order to process, often need to use various frock clamps and device positions workpiece, in prior art, lathe is for the location of workpiece vertical direction, often with custom-designed fixture, realize, yet for the processing of the higher workpiece of the automaticity in some production lines, common fixture often efficiency is lower, can not meet the demand of automated production.
Utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, and a kind of hold down gag of lathe is provided, and it is reliable, and efficiency is higher, can meet the demand of automated production.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of hold down gag of lathe, comprise frame, described frame has vertical guide hole, in described frame, be installed with hydraulic cylinder, the piston rod of described hydraulic cylinder is connected with guide rod straight down, described guide rod slides and runs through described guide hole and extend described guide hole, the bottom of described guide rod is hinged with horizontally disposed pressing plate, described pressing plate below has two thimbles, the top of described pressing plate is provided with limiting plate near described pressing plate, described limiting plate fixed cover is located on described guide rod, the side that the top of described pressing plate is positioned at described guide rod is fixedly connected with vertical auxiliary rod, described auxiliary rod slides and runs through described frame, the top of described auxiliary rod is accommodated by spring spool, in described frame, be connected with the installing plate of level, described spring spool stands upside down and is arranged on described installing plate below, in described spring spool, be provided with spring, one end of described spring and described installing plate butt, the other end of described spring is connected with described auxiliary rod.
Further, the effective travel of described piston rod equates with the effective travel of described auxiliary rod in described spring spool.
The hold down gag of a kind of lathe described in the utility model, comprise frame, frame has vertical guide hole, in frame, be installed with hydraulic cylinder, the piston rod of hydraulic cylinder is connected with guide rod straight down, guide rod slides and runs through guide hole and extend guide hole, the bottom of guide rod is hinged with horizontally disposed pressing plate, pressing plate below has two thimbles, the top of pressing plate is provided with limiting plate near pressing plate, limiting plate fixed cover is located on guide rod, the side that the top of pressing plate is positioned at guide rod is fixedly connected with vertical auxiliary rod, auxiliary rod slides and runs through frame, the top of auxiliary rod is accommodated by spring spool, in frame, be connected with the installing plate of level, spring spool stands upside down and is arranged on installing plate below, in spring spool, be provided with spring, one end of spring and installing plate butt, the other end of spring is connected with auxiliary rod.The hold down gag of the lathe of this structure, it is reliable, and the piston rod by hydraulic cylinder drives guide pillar to slide, and then band dynamic pressure plate moves downward, and auxiliary rod glides smoothly under the elastic force effect of spring simultaneously, and efficiency is higher, has met the demand of automated production.
