Description
Technical field
The utility model belongs to machine tool technology field, specifically, and the particularly adjustable axial positioning mechanism of a kind of lathe.
Background technology
During lathe in machining axial workpiece, according to processing needs, a part for part need stretch in main shaft, and part needs axial location.Existing locate mode utilizes the outer face of workpiece to position, and must measure, not only complex operation before such clamping to workpiece, and workload is large, can reduce the efficiency of processing, and also have impact to the machining accuracy of workpiece.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lathe easy and simple to handle, good reliability adjustable axial positioning mechanism.
The technical solution of the utility model is as follows: the adjustable axial positioning mechanism of a kind of lathe, comprise angling cylinder (1) and pull bar (2), pull bar (2) is connected with the piston rod of angling cylinder (1), its key is: in described pull bar (2), arrange locating ring (3), the front end of this locating ring (3) is formed with guiding conehead (3a), rear end suit centering ring (4) of locating ring (3), centering ring (4) and pull bar (2) matched in clearance, the rear end of described locating ring (3) is connected with the front end of connecting rod (6) by turning pull bar (5), admittedly overlap limit at the middle front part of connecting rod (6) to shake ring (7), limit shake ring (7) and pull bar (2) matched in clearance, angling cylinder (1) is stretched out in the rear end of described connecting rod (6), the rear portion of connecting rod (6) is thread segment, this thread segment is set with Connection Block (8), described Connection Block (8) is fixed by the cylinder body of bolt and angling cylinder (1).
Adopt above technical scheme, during clamping workpiece, workpiece inner face is fitted on locating ring locating surface, realizes location.Between workpiece hole and centering ring cylindrical, gap is very large, and only as coarse positioning, the large guiding conical surface on guiding conehead is convenient to clamping workpiece.Pull bar moves axially together with the piston rod of angling cylinder, and Connection Block does not move axially, and the centering ring be attached thereto also does not move axially, and realizes the axial location of workpiece.When Workpiece length is different, regulating connecting rod; When workpiece in different size, change locating ring.Centering ring and locating ring match, and form 2 supports, to guarantee the reliability of the utility model in pull bar inner position.Enough reaches are left at connecting rod rear portion, so that according to the length of workpiece and clamping position adjustment turnover position.In addition, as user be not used further to process such axial workpiece time, pull down this parts, lathe can use in the same old way.
The described front end turning pull bar (5) is formed with stud, this stud screws in locating ring (3), step surface on the front end of centering ring (4) and locating ring (3) is close to, rear end and the step surface turned on pull bar (5) of centering ring (4) are close to, the front end of connecting rod (6) is inserted in by the described rear end turning pull bar (5), both threaded engagement, and by the upper nut check be set with of connecting rod (6).Above structure turn pull bar be connected between locating ring and connecting rod firm, easy accessibility, good concentricity.
For the ease of assembling, make the limit ring that shakes be set with firm on connecting rod, the described limit screw that ring (7) wears by radial direction that shakes holds out against on connecting rod (6), and this is screw concealed shakes in ring (7) in limit.
Beneficial effect: the utility model can realize the axial location of axial workpiece, and location is reliable, simple, convenient, not only effectively reduce workload, substantially increase the efficiency of processing, and the machining accuracy of workpiece can be guaranteed, have that reasonable in design, structure is simple, highly versatile, adjustment change the features such as convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, pull bar 2 is hollow-core construction, and this pull bar 2 is connected with the piston rod of angling cylinder 1, and pull bar 2 is located in main shaft.In pull bar 2, arrange locating ring 3, the front end of this locating ring 3 is formed with guiding conehead 3a, and 3a is pre-small post-large for guiding conehead.Connecting rod 6 is set at the rear of locating ring 3, is provided with between connecting rod 6 and locating ring 3 and turns pull bar 5, locating ring 3, turn the axial line of pull bar 5 and connecting rod 6 three point-blank.The front end turning pull bar 5 is formed with stud, and this stud screws in locating ring 3, both threaded engagement.The front end of connecting rod 6 is inserted in by the rear end turning pull bar 5, both threaded engagement, and by the nut check that connecting rod 6 is set with.
As shown in Figure 1, in the rear end of locating ring 3 suit centering ring 4, centering ring 4 and pull bar 2 matched in clearance.Step surface on the front end of this centering ring 4 and locating ring 3 is close to, and rear end and the step surface turned on pull bar 5 of centering ring 4 are close to.To shake ring 7 in the middle front part suit limit of connecting rod 6, limit is shaken ring 7 and pull bar 2 matched in clearance, and the screw that ring 7 is worn by radial direction and limit is shaken holds out against on connecting rod 6, and this is screw concealed shakes in ring 7 in limit.Angling cylinder 1 is stretched out in the rear end of connecting rod 6, and the rear portion of connecting rod 6 is thread segment, this thread segment is set with Connection Block 8, Connection Block 8 and connecting rod 6 threaded engagement, and by nut check, and Connection Block 8 is fixed by the cylinder body of bolt and angling cylinder 1.
