Abstract
The utility model relates to a novel elastic turning tool which comprises a fixed plate, a sliding device, an upper cross plate, a tool handle, a spring and a turning tool blade. The sliding device is fixedly arranged on the lower portion of one side of the fixed plate and connected with the tool handle vertically in a sliding mode, the middle portion of the tool handle is connected with the upper cross plate fixedly arranged at the upper end portion of the fixed plate correspondingly through the spring, and the turning tool blade is fixedly arranged at the front end portion of the tool handle. The front end portion of the tool handle on one side of the turning tool blade and the turning tool are arranged at one end of a locating shaft parallelly, a cantilever end of the locating shaft is arranged at the front end of the turning tool blade, and a bearing is arranged between the locating shaft and the tool handle in a coaxial mode. By arranging the bearing between the locating shaft and the tool handle of the turning tool in a coaxial mode, a part drives the locating shaft to rotate when the turning tool conducts chamfering, and the problem that the locating shaft abrades the surface of the part is solved. The novel elastic turning tool is simple in structure and scientific and reasonable in design, improves the appearance quality of the part, prolongs the service life of the locating shaft and guarantees uniformity of product machining.
Description
Technical field
The utility model belongs to the machined field, relates to cutter, especially a kind of novel elastic lathe tool.
Background technology
At present, but the lathe tool that has occurred a kind of pairing approximation circular pieces chamfering on the market, this lathe tool comprises fixed head, handle of a knife, spring and turning insert, the lower end of fixed head vertically slidely connects the handle of a knife of horizontal positioned, the middle part of this handle of a knife links together by a spring and the transverse slat that is packed in the fixed head upper end, the front end end of described handle of a knife is fixed with turning insert, the parallel end that installs a locating shaft with this lathe tool of the handle of a knife leading section of this turning insert one side, the cantilever end of this locating shaft is positioned at the front end of turning insert.When carrying out chamfering, this locating shaft cantilever end is overlapped on the outer rim upper end face of sub-circular part (hereinafter to be referred as part), does radial displacement by the relative part of spring band moving knife handle, thereby realizes the purpose of part chamfering.
But the problem that above-mentioned lathe tool exists is: because locating shaft is packed in the handle of a knife, part rotates at a high speed with locating shaft and produces friction in process, and the phenomenon that causes the part outer rim to be polished easily influences the part outward appearance, thereby has reduced the quality of part.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of pairing approximation circular pieces chamfering simple in structure, quick and novel elastic lathe tool that can the wearing part surface are provided.
Scheme of the present utility model is achieved in that
A kind of novel elastic lathe tool, comprise fixed head, carriage, upper cross plate, handle of a knife, spring and turning insert, one side bottom of this fixed head is fixed with carriage, this carriage vertically slidely connects handle of a knife, the middle part of this handle of a knife links together with the corresponding upper cross plate that is packed in the fixed head upper end by spring, the front end end of described handle of a knife is fixed with turning insert, one end of coaxial installation one locating shaft of the handle of a knife leading section of this turning insert one side and this lathe tool, the cantilever end of this locating shaft is positioned at the leading section of turning insert, coaxial installation one bearing between described locating shaft and the handle of a knife.
And described carriage comprises chute and slide block, and this chute vertically is packed in the side bottom of fixed head, vertically slidely connects slide block on chute.
And a limited block is installed in the bottom of described chute.
Advantage of the present utility model and good effect are:
By at coaxial installation one bearing between the locating shaft of this lathe tool and the handle of a knife, thereby realized that this lathe tool part when chamfering drives the locating shaft rotation, avoids the problem on locating shaft wearing part surface.The utility model is simple in structure, design science is reasonable, not only improves the presentation quality of part, has prolonged the life-span of locating shaft, and has guaranteed the uniformity of product processing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The perspective view that Fig. 2 is installed together for handle of a knife, turning insert and locating shaft among Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view Amplified image.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of novel elastic lathe tool, as shown in Figure 1, comprise fixed head 1, upper cross plate 2, lower cross plate 4, carriage, spring 3, handle of a knife 5 and turning insert 6, one side bottom of this fixed head vertically is equipped with carriage, this carriage slidely connects the lower cross plate of horizontally set, vertical plate upper end at corresponding lower cross plate is fixed with upper cross plate, this upper cross plate links together by spring and the lower cross plate of vertical setting, the lower surface of this lower cross plate is equipped with handle of a knife, the front end end of this handle of a knife is fixed with turning insert, one end of coaxial installation one locating shaft 7 of the handle of a knife leading section of this turning insert one side and this lathe tool, the cantilever end of this locating shaft is positioned at the leading section of turning insert.
Innovative point of the present utility model is:
Coaxial installation one bearing 12 between described locating shaft and the handle of a knife, as shown in Figure 3.
In the present embodiment, described carriage comprises chute 11 and slide block 9, and this chute vertically is packed in the side of fixed head, vertically slidely connects slide block on chute.
A limited block 10 is installed in the bottom of described chute, and purpose is that anti-limited slip block comes off.
Operation principle of the present utility model is:
At first the elasticity lathe tool is fixed on lathe or the Digit Control Machine Tool, mobile elasticity lathe tool makes the cantilever end of locating shaft be overlapped on the outer rim upper end of part 8 then, the movement of handle of a knife makes spring be in compressive state, and then it is the elasticity lathe tool is traversing to part gradually, do radial displacement by the relative part of spring band moving knife handle, thereby finish chamfering work.Part drive locating shaft together rotates in the process of carrying out chamfering, thereby has effectively avoided the problem on locating shaft wearing part surface.
Elasticity lathe tool in the present embodiment is positioned at part outer rim upper end and carries out chamfering, and according to demand, chamfering is carried out in a side that also the elasticity lathe tool can be positioned at part, and its operation principle is identical, so the application repeats no more.
