Abstract
The utility model belongs to the technical field of machinery manufacturing, aims to solve the technical problem of deformation of tool holders due to the fact that right shoulders of the tool holders are separated from bottoms of rams when existing tool holders of heavy-type vertical lathes are under severe conditions of continuous large cutting forces, chip-breaking cutting and the like, and provides an anti-deformation tool holder of a heavy-type vertical lathe. According to the anti-deformation tool holder, a fixing plate is added on a right shoulder of the tool holder on the basis of an original tool holder structure, the binding force of the right shoulder and a ram is increased by the aid of the fixation of the fixing plate and the ram, and the technical problem of the deformation of the tool holder due to the fact that the right shoulder is separated from the ram under stress to form a gap under the severe conditions of continuous large cutting forces, chip-breaking cutting and the like is solved. The tool holder is simple in structure, very convenient to machine, transform and installed and widely applicable to configuration of the heavy-type vertical lathe.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of heavy vertical lathe anti-deformation cutter holder.
Background technology
Turning tool holder is vertical car carries out workpiece processing most important core main part for clamping cutter, is also one of important guarantee of complete machine tool machining accuracy and reliability simultaneously.The structure of the turning tool holder of heavy vertical lathe is as Fig. 1, shown in Fig. 2, it comprises the fixture block body 1 of a square shape, be provided with a cutter clip slot 2 at the middle part of fixture block body, the sidewall of cutter clip slot 2 one sides is provided with some edge bearing pieces 3, connect the assembling clamping bolt 4 corresponding with edge bearing piece at the sidewall of cutter clip slot opposite side, the top of fixture block body is provided with and coordinates positioning key 5 and the locating shaft 6 installed with ram, the upper surface of the fixture block body of positioning key 5 both sides forms respectively the left shoulder 9 and the right shoulder 10 that contact with ram bottom, cutter clip slot top be provided with two with the fixing bolt hole 8 of ram 7, two bolts hole 8 are distributed in the both sides of locating shaft, set bolt 11 is fixed cutter holder and ram by bolt hole 8.But in use find, in the time of processing work (lathe regulation is main story counterclockwise), right shoulder 10 is subject to left power effect on the lower side, in the time that cutter holder continues the mal-conditions such as larger or the cutting of section bits in cutting force, right shoulder 10 easily separates and forms gap with ram bottom, this situation has a strong impact on Workpiece Machining Accuracy, has also caused cutter holder deformation effect cutter holder service life simultaneously.
Summary of the invention
Continuing under large cutting force effect or the cutting of section bits waits under mal-condition for overcoming current heavy vertical lathe cutter holder, separating the technical problem that causes cutter holder to be out of shape bottom the right shoulder of cutter holder and ram, the utility model provides a kind of heavy vertical lathe anti-deformation cutter holder.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: heavy vertical lathe anti-deformation cutter holder, it comprises the fixture block body of a square shape, be provided with a cutter clip slot at the middle part of fixture block body, the sidewall of cutter clip slot one side is provided with some edge bearing pieces, connect the assembling clamping bolt corresponding with edge bearing piece at the sidewall of cutter clip slot opposite side, the top of fixture block body is provided with and coordinates positioning key and the locating shaft installed with ram, the fixture block body upper surface of positioning key both sides forms respectively the left shoulder and the right shoulder that contact with ram bottom, cutter clip slot top be provided with two with the fixing bolt hole of ram, two bolts hole are distributed in the both sides of locating shaft, it is characterized in that: the outside of the right shoulder of described fixture block body is provided with an outward extending fixed head, the upper surface of fixed head and the right shoulder of fixture block body are positioned on same level line, on fixed head, be provided with some fixing threaded holes.
This heavy vertical lathe anti-deformation cutter holder by increasing fixed head on original cutter holder basis, the adhesion of the right shoulder of cutter holder and ram is strengthened, can effectively prevent that the mal-condition bottom right shoulder such as lasting large cutting force or the cutting of section bits from separating the technical problem that formation gap causes cutter holder distortion after stressed with ram.This holder structure is simple, and process and remould and install very conveniently can be widely used in the configuration of heavy vertical lathe.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in accompanying drawing 3 and accompanying drawing 4, this heavy vertical lathe anti-deformation cutter holder, it comprises the fixture block body 1 of a square shape, be provided with a cutter clip slot 2 at the middle part of fixture block body, the sidewall of cutter clip slot 2 one sides is provided with some edge bearing pieces 3, connect the assembling clamping bolt 4 corresponding with edge bearing piece at the sidewall of cutter clip slot opposite side, the top of fixture block body 1 is provided with and coordinates positioning key 5 and the locating shaft 6 installed with ram.
As shown in Figure 3, cutter clip slot 2 tops are provided with two and are distributed in the both sides of locating shaft 6 with fixing bolt hole 8, two bolts hole of ram, and set bolt 11 is fixed cutter holder and ram 7 by bolt hole 8.
As shown in Figure 3, when after this cutter holder and ram 7 secure bond, the fixture block body upper surface of positioning key 5 both sides forms respectively the left shoulder 9 and the right shoulder 10 that contact with ram bottom.
As shown in Figures 3 and 4, the outside of the right shoulder 10 of fixture block body 1 is provided with an outward extending fixed head 12, and the right shoulder 10 of the upper surface of fixed head 12 and fixture block body is positioned on same level line, is provided with some fixing threaded holes 13 on fixed head 12.
When installation, the right shoulder 10 of fixture block body and fixed head 12 contact with ram bottom simultaneously, except adopting set bolt 11 fixes this cutter holder and ram, the fixing threaded hole 13 that fixed head 12 passes on it by bolt is simultaneously fixed with ram bottom, the adhesion of the right shoulder 10 of so effective increase cutter holder and ram bottom, can effectively prevent that the mal-condition bottom right shoulder such as lasting large cutting force or the cutting of section bits from separating the technical problem that formation gap causes cutter holder distortion after stressed with ram.
