Detailed description of the invention
Embodiment 1:
As in Fig. 1 ~ 4, a kind of lathe multiple spot supplemental support clamping device, be provided with T-shape slide block 16 bottom pile crown matrix 11, the both sides of pile crown matrix 11 are provided with auxiliary support arm 14, and pile crown matrix 11 and auxiliary support arm 14 are provided with multiple bracing or strutting arrangement.T-shape slide block 16 is arranged in the chute 3 between chuck 4 upper clipping claw 2, with each claw 2 circumferentially at a distance of 45 degree.Formed for the supplemental support of workpiece 5 outside claw 2 clamping.
As shown in fig. 1, pile crown matrix 11 self is provided with multiple stage, the highest stage is as the support datum level of pile crown matrix 11, as shown in Fig. 1,3 and 6, two other stage one is provided with the first bolt support 12 or hydraulic auxiliary support 17, the first bolt support 12 is herein provided with hexagon termination, to turn adjustment with spanner, another one stage is then for being fixedly connected with T-shape slide block 16 by connecting bolt 15.First bolt support 12 is provided with locking nut 13, for clamping screw.
As shown in Figure 2, auxiliary support arm 14 is provided with multiple second bolt support 12', and except adopting the structure identical with the first bolt support 12, bolt can also be adopted to pass the structure of auxiliary support arm 14, and locking nut 13 is positioned at the below of auxiliary support arm 14.Structure thus, is convenient to regulate bearing height.The bolt head of hexagonal in preferred employing, regulates more convenient.
Preferred as in Fig. 2, auxiliary support arm 14 is fixedly connected with pile crown matrix 11 by connecting bolt 15.So that processing.
In this example, preferably as shown in Figure 1, described multiple bracing or strutting arrangements lay respectively at the pitch circle of different-diameter.Support described herein also comprises the support of the datum level of pile crown matrix 11 upper surface, as in Fig. 1, and the first supplemental support pitch circle A that the second bolt support 12' corresponding to auxiliary support arm 14 termination is respectively formed; The second supplemental support pitch circle B that the second bolt support 12' in the middle part of auxiliary support arm 14 is formed; The pile crown supplemental support pitch circle C that the first bolt support 12 on pile crown matrix 11 is formed; The pile crown reference support pitch circle D that pile crown matrix 11 upper end datum level is formed.Structure thus, the supplemental support increased in this device point is distributed in different circumference from support floors, and the radial moment of workpiece claw clamping force formed is divided into multistage, decreases the deflection deformation that clamping force causes.Decrease the deflection deformation of workpiece circumferencial direction.Make claw clamping force act on Workpiece clamping completely, avoid the moment producing harmful amount of deflection.Use rational clamping force just effectively can support workpiece, ensure clamping rigidity.When turning, the moment deflection deformation that the rigidity of multi-point support can be born lathe tool extruding force and be produced, can keep larger bite, cutting linear velocity and the amount of feeding during turning.
Adopt device of the present utility model, have multiple installation way, as in Fig. 5, utilize the stage on pile crown matrix 11,
Clamping is in the lower end of workpiece and outer rim, and realize the installation way of similar claw 2, which is applicable to the flange part with stage.As the installation way in Fig. 1,6, each bracing or strutting arrangement is all positioned at the bottom of workpiece 5, be then applicable to plane thin-wall flange part.And as in Fig. 4,7, be then suitable for and can not clamp, need turning to flatten the flange part in face, can be threaded with the technique screw 18 of workpiece 5 by bolt support, between workpiece 5 and pile crown matrix 11 or auxiliary support arm 14, be provided with cushion block 19.Adopt the method for technique screw axial tightening, bolt tightening will be adjusted on bracing or strutting arrangement, claw can not be adopted to clamp and directly turning.
Embodiment 2:
Although the structure in embodiment 1 can realize good clamping and support, need during clamping to turn more bolt, and locking nut 13, consuming time longer, for large batch of production, efficiency is lower.
Further in preferred scheme, as shown in Figure 7,8, by the first bolt support 12 in embodiment 1 and the second bolt support 12' part or all of replace with hydraulic auxiliary support 17, structure thus, be convenient to the support realizing automatically controlling, thus significantly improve clamping efficiency.
Further in preferred scheme, the hydraulic stem of hydraulic auxiliary support 17 is provided with pressure sensor 174.By pressure sensor 174, can guarantee that the top lift of each hydraulic auxiliary support 17 is all identical, avoid making because the top lift of hydraulic auxiliary support 17 is different workpiece produce distortion.And the manual adjustment compared in embodiment 1, precision is higher.And then realize Automated condtrol.
Hydraulic auxiliary support 17 in this example adopts orthoscopic hydraulic cylinder, or structure as described below.
Preferred scheme, as in Fig. 7,8, the structure of described hydraulic auxiliary support 17 is: be provided with hydraulic stem 171 in cylinder body 172, cylinder body 172 inwall is provided with cylinder body helicla flute 173, hydraulic stem 171 is provided with and is slidably matched with cylinder body helicla flute 173 and forms the catch 175 sealed, and cylinder body 172 is provided with the infusion port 177 communicated respectively with cylinder body helicla flute 173 two ends.Structure thus, hydraulic stem 171 is under the thrust of hydraulic oil for catch 175, drive hydraulic stem 171 spiral or decline, because the jacking distance of a pitch is assigned to circumferentially whole, therefore Adjustment precision is further increased, and this structure also achieves self-locking, avoid precision when affecting support because of the hydraulic oil pressure fluctuation in process.
Preferred scheme is as in Fig. 8 further, on hydraulic stem 171, is positioned at below catch 175 and is provided with body of rod helicla flute 176.Structure thus, increase effectively the area of catch 175, contributes to when jacking, produces larger thrust.
The method comprising device use in embodiment 1 and 2 of the present utility model, comprises the following steps:
One, position and the direction of the T-shaped chute 3 of chuck is stuck according to diameter of work size adjustment pile crown matrix 11;
Two, unclamp all locking nuts 13, turn down bolt height, or reduce the height of hydraulic stem 171 in hydraulic auxiliary support 17;
Three, workpiece is positioned on pile crown matrix reference support face, uses claw preliminary school circle, pre-pressing;
Four, workpiece planarization is adjusted in school, and the corresponding adjustment bolt support that turns lives workpiece, locking locking nut, or the hydraulic stem 171 of hydraulic auxiliary support 17 rises, until the pressure signal that pressure sensor 174 sends reaches requirement.
In this step, if workpiece is green state, directly adjust carrying bolt; Need borrow as workpiece and just process, need corresponding adjustment to do reversible deformation process; As being in finish turning state, remaining unchanged after first each point being adjusted to a plane and can directly use.
Five, finally tighten claw, check and can carry out procedure after gapless between each strong point and workpiece.
