Abstract
The utility model relates to a machine tool, particularly a positioning device for bar cutting machine. Because a material-preventing oil cylinder is arranged on a movable die holder, the piston rod of the material-preventing oil cylinder is connected with a material-preventing frame; the cut length of the rod material can be controlled conveniently by adjusting the length of the material-preventing rod on the material-preventing frame. The utility model has the advantages of high work efficiency, small labor intensity, small error of clipping rod material, and the utility model is especially suitable for clipping rod material.
Description
The utility model relates to lathe, specifically a kind of location stop gauge of bar shears.
" round steel cutting machine " by comrade Han Shuying of Rongcheng City, Shandong Province Qinghe Industry Corporation invention, the patent No. is 93232153.4, this round steel cutting machine is by support, hydraulic cylinder assembly, the cover half seat, cover half, the pressing plate slideway, the dynamic model seat, dynamic model, moulded board, connecting rod and pin, compositions such as trip bolt, the dynamic model seat links through pressing plate slideway and cover half seat, the connecting rod two ends join with hydraulic cylinder assembly and dynamic model seat respectively, piston during work in the hydraulic cylinder assembly moves up and down, on the relative cover half seat of connecting rod drive dynamic model seat, rotate to an angle, make the dynamic model that is installed on dynamic model seat and the cover half seat, cover half also rotates to an angle relatively, to realize cutting off the purpose of bar, the round steel cutting machine of this structure is not located stop gauge, has inefficiency, labour intensity is big, cut off the big deficiency of bar error.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of location stop gauge that operating efficiency improves, bar is cut off the little bar shears of error that makes is provided.
For achieving the above object, feature of the present utility model is that the backgauge oil cylinder is fixed on the big end that is connected with the dynamic model seat through connecting plate, backgauge oil cylinder piston bar is connected with the backgauge frame, the backgauge frame is provided with support holes and pilot hole, coupling has material blocking rod in the support holes, lead is connected with connecting plate, and lead is provided with the spacing collision block in back, is respectively equipped with front limit switch and back limit switch on connecting plate and the backgauge frame.
The utility model is owing to be provided with the backgauge frame, and the backgauge frame is provided with material blocking rod, regulates the length of material blocking rod, can control the shearing length of bar easily, have high efficiency, labour intensity little, cut off the little advantage of bar error.
