Abstract
The utility model discloses an antiskid pressing plate for a lathe tool bar which comprises a pressing plate body, a threaded hole which is not communicated with the pressing plate body is formed in the center of the upper end of the pressing plate body, the size of the inner diameter of the threaded hole is the same as the size of the compression end of a lock screw on a lathe tool rest, and a plurality of spike like thorn sets are arranged on the lower end face of the pressing plate body to form a thorny rough surface. According to the antiskid pressing plate for the lathe tool bar, the lock screw and an antiskid pressing plate can only make rotational motion and cannot make relative sliding motion, the antiskid pressing plate of the lathe tool bar is pressed on the lathe tool bar tightly through the lock screw, and the original single point contact between the tool bar and the lower end surface is changed into multi-point contact due to the fact that the lower end surface of the antiskid pressing plate is the thorny rough surface. Therefore, the friction force between the antiskid pressing plate and the tool bar is increased, the lathe tool bar is not prone to sliding under the working condition of heavy load cutting, the stability of the lathe tool bar under heavy load is increased greatly, and the working efficiency of equipment is improved.
Description
Technical field
The utility model relates to the metal cutting tool field, specifically refers to the anti-skidding pressing plate of a kind of lathe tool knife bar.
Background technology
At present, when blank class large-scale workpiece is carried out roughing, because larger to the cutting output of workpiece, the various loads and the impact shock that cause lathe tool to be subject in working angles are larger, since common cutter platform to the lathe tool knife bar locking mode be housing pin point contact compression, the lathe tool knife bar easily produces under the cutting operating mode of heavy load and slides, thereby cause the displacement of Lathe tool tip, cause the damage of converted products dimensional error and lathe tool, also reduced greatly quality and the efficient of rough-wrought product.
The utility model content
Technical problem to be solved in the utility model provides a kind of pressing plate that can prevent that car from sliding in process to knife bar, thereby has improved quality and the production efficiency of product.
The anti-skidding pressing plate of a kind of lathe tool knife bar described in the utility model comprises the pressing plate main body, is provided with a screw hole that does not run through plate body in the center, upper end of pressing plate main body, and lock screw compresses to hold and is harmonious on its internal diameter and the lathe cutter saddle.
Further improve, the lower surface of described pressing plate main body is provided with many group thorniness, forms a thorniness type matsurface.
Further improve, described thorniness is pointed type again.
The beneficial effects of the utility model:
The utility model compared with prior art, this center, anti-skidding pressing plate upper end is provided with a screw hole that does not run through plate body, its internal diameter size matches with lock screw compression end on the lathe cutter saddle, make to produce between lock screw and the anti-skidding pressing plate and rotatablely move, and without relatively sliding motion, then by lock screw the anti-skidding pressing plate of lathe tool knife bar is pressed on the lathe tool knife bar, owing to being thorniness type matsurface below the anti-skidding pressing plate, the multiple spot compacting that is changed into the anti-skidding pressing plate of lathe tool knife bar by the single-point contact of original housing pin that contacts with knife bar, thereby increased the frictional force between anti-skidding pressing plate and the knife bar, make the lathe tool knife bar under the operating mode of heavy duty cutting, be difficult for sliding, greatly increase the stability of lathe tool knife bar under heavy duty, and improved production efficiency of equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the anti-skidding pressing plate of a kind of lathe tool knife bar described in the utility model, comprise pressing plate main body 1, be provided with a screw hole 2 that does not run through plate body in the center, upper end of pressing plate main body 1, lock screw compresses to hold and is harmonious on its internal diameter and the lathe cutter saddle, make to produce between lock screw and the anti-skidding pressing plate to rotatablely move, and without relatively sliding motion, then by lock screw the anti-skidding pressing plate of lathe tool knife bar is pressed on the lathe tool knife bar; The lower surface of pressing plate main body 1 is provided with the pointed type thorniness 3 of many groups, form a thorniness type matsurface, the multiple spot compacting that is changed into the anti-skidding pressing plate of lathe tool knife bar by the single-point contact of original housing pin that contacts with knife bar, thereby increased the frictional force between anti-skidding pressing plate and the knife bar, made the lathe tool knife bar under the operating mode of heavy duty cutting, be difficult for sliding.
The utility model provides thinking and the implementation method of the anti-skidding pressing plate of a kind of lathe tool knife bar; concrete application approach is a lot; the above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
