Description
Technical field
This utility model relates to the axial direction positioning device of a kind of numerical control lathe main shaft jump ring, belongs to the parts fixation technical field of plant equipment.
Background technology
On numerically controlled lathe, conventional main shaft jump ring, as the fixture of holding parts, owing to structure and the precision of main shaft jump ring are preferable, is widely used in manufacture field.But in concrete production process, jump ring lacks axial direction positioning device, jump ring end face can only be relied on to position with particular tool.Concrete operations are to be moved by cutter to a certain fixed position of program setting, open machine tool door and unclamp jump ring, and then the end face of part to be processed is pulled to tool face laminating, and clamping spindle jump ring closes machine tool door the most again.Current this location mode operates complexity and positioning precision is low, it is impossible to meet the precision of part, bulk of components size difference big and cannot meet being switched fast and processing of multiple types part in production process.
Utility model content
The purpose of this utility model is, it is provided that the axial direction positioning device of a kind of numerical control lathe main shaft jump ring.The concordance axially positioned during each clamping parts can be ensured, to facilitate the processing request of batch part.
The technical solution of the utility model:
The axial direction positioning device of a kind of numerical control lathe main shaft jump ring, including locating shaft, locating shaft one end is provided with coarse adjustment screw rod, and coarse adjustment screw rod is provided with the connection lid and coarse adjustment locking nut being connected with main shaft jump ring；Connecting lid endoporus and be provided with the female thread being connected with locating shaft, connecting lid outside cylinder is step post, and the minor diameter cylindrical of step post is provided with the connection screw thread supporting with main shaft jump ring internal thread hole；The locating shaft other end is provided with fine setting screw；Fine setting screw is connected with fine setting screw flight, and fine setting screw rod is provided with fine setting locking nut.
In aforementioned positioner, the pitch of described fine setting screw is less than the pitch of coarse adjustment screw rod.
In aforementioned positioner, the location end face that the end face stretching out locating shaft one end is part of described fine setting screw rod.
Compared with prior art, this utility model simple in construction, it is easy to manufacture.It is axially precisely positioned that the mode using coarse adjustment and fine setting to match can realize main shaft jump ring, reduces the labor intensity of operator, it is ensured that the consistent and required precision with batch accessory size；Meanwhile, the highly-efficient processing of different product kind and the service efficiency of jump ring can be realized.

Being labeled as in figure: 1-locating shaft, 2-coarse adjustment locking nut, 3-connect lid, 4-main shaft jump ring, 5-fine setting locking nut, 6-fine setting screw rod, 7-coarse adjustment screw rod, 8-fine setting screw, 9-positions end face, 10-clamps hole, 11-taper surface, 12-retraction slot.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as to any restriction of the present utility model.
A kind of axial direction positioning device of numerical control lathe main shaft jump ring, as shown in Figure 1: including that locating shaft 1, locating shaft 1 one end are provided with coarse adjustment screw rod 7, coarse adjustment screw rod 7 is provided with the connection lid 3 and coarse adjustment locking nut 2 being connected with main shaft jump ring 4；Connecting lid 3 endoporus and be provided with the female thread being connected with locating shaft 1, connecting lid 3 outside cylinder is step post, and the minor diameter cylindrical of step post is provided with the connection screw thread supporting with main shaft jump ring 4 internal thread hole；Locating shaft 1 other end is provided with fine setting screw 8；Fine setting screw 8 is threadeded with fine setting screw rod 6, and fine setting screw rod 6 is provided with fine setting locking nut 5.The pitch of fine setting screw 8 is less than the pitch of coarse adjustment screw rod 7.The location end face 9 that end face is part stretching out locating shaft 1 one end of fine setting screw rod 6.
Embodiment
Main shaft jump ring 4 used in this example is as shown in Figure 1, one end that main shaft jump ring 4 is connected with equipment is cylindric, main shaft jump ring 4 other end is taper surface 11, and the end face of taper surface 11 is provided with the clamping hole 10 of holding parts, and taper surface 11 1 sections is provided with one group of radial uniform retraction slot 12.Retraction slot 12 is externally provided with contraction set (being not drawn in figure), by coordinating of moving axially of overlapping of contraction and taper surface 11, extrudes taper surface 11, makes retraction slot 12 shrink so that clamping hole 10 diameter and reducing, reach the purpose of Clamp blocks.Owing to existing main shaft jump ring 4 is not provided with axial direction positioning device, therefore when carrying out batch machining, want the axial location carefully to part every time, operate and bother very much.For the deficiency overcoming existing main shaft jump ring 4 to exist, devise the main shaft jump ring axial direction positioning device of the present invention.
The main shaft jump ring axial direction positioning device of this example is as shown in Figure 1.Including locating shaft 1, locating shaft 1 one end is provided with coarse adjustment screw rod 7, and coarse adjustment screw rod 7 is provided with the connection lid 3 and coarse adjustment locking nut 2 being connected with main shaft jump ring 4；Connecting lid 3 endoporus and be provided with the female thread being connected with locating shaft 1, connecting lid 3 outside cylinder is step post, and the minor diameter cylindrical of step post is provided with the connection screw thread supporting with main shaft jump ring 4 internal thread hole；Locating shaft 1 other end is provided with fine setting screw 8；Fine setting screw 8 is threadeded with fine setting screw rod 6, and fine setting screw rod 6 is provided with fine setting locking nut 5.The pitch of fine setting screw 8 is less than the pitch of coarse adjustment screw rod 7.The location end face 9 that end face is part stretching out locating shaft 1 one end of fine setting screw rod 6.
During concrete operations, as it is shown in figure 1, first screwed in by fine setting screw rod 6 in the fine setting screw 8 of locating shaft 1 one end, screw-in depth is about about the 1/2 of the thread segment of fine setting screw rod 6, and is locked by fine setting locking nut 5；Again by the screw connecting lid 3 screw-in main shaft jump ring 4 one end, and the end face making on connection lid 3 boss between major diameter and minor diameter push against main shaft jump ring 4 screw tightens, and locating shaft 1 is screwed in connection lid 3, after kind of calliper position suitable, just coarse adjustment locking nut 2 is locked.Then the main shaft jump ring being provided with axial direction positioning device is arranged on lathe use.
