Abstract
The utility model relates to a machine tool hilt structure, which comprises a taper part, a tool apron part, an annular part and a contraction and expansion adjusting structure formed on the surface of the annular part; wherein, the contraction and expansion adjusting structure abuts against the taper part and is a groove or hole; when the thickness of the annular part is increased, and the hilt can be arranged on a spindle, the annular part can lean against the end face of the spindle so as to improve the rotational stability; moreover, the groove or hole can adjust the deformation caused by thermal expansion and dissipate heat, so that the hilt can be easily removed from the spindle in the case of blade damage.
Description
[technical field]
The utility model is about a kind of hilt structure, particularly is installed on the hilt structure of tool machine spindle end.
[background technology]
General cutting element is to finish cutwork by cutter and workpiece relative motion.The state that rotates with cutter is an example, and this cutter normally is installed on the hilt, and then this hilt is installed on the main shaft of toolroom machine, rotates at a high speed by main shaft to drive hilt and cutter rotates.
See also Fig. 1, general hilt (10) comprises three parts, i.e. tapering (11), tool rest portion (13) and the position ring portion (15) between the two.Wherein tapering (11) in order to inserting in the main shaft (17), by the taper endoporus (18) of the outward appearance applying main shaft (17) of pushing and drawing shape to reach the purpose of combination.In this kind structure, the end face (19) of main shaft (17) does not contact the surface of ring portion (15), and in other words, hilt (10) easily produces unsettled rotary state when high speed rotating.
Rotate unsettled situation in order to solve hilt (10), see also Fig. 2, a side surface of ring portion (15) disposes a supplementary plate (22) and mat lock member (24) is fixed on the ring portion (15).Thus, when tapering (11) placed the endoporus (18) of main shaft (17), the end face (19) of main shaft (17) can abut in the surface of supplementary plate (22).
The stability when though the disclosed structure configuration of Fig. 2 can improve hilt (10) rotation, so the contact-making surface because of main shaft (17) and hilt (10) is all fit-state, the heat expansion effect that is produced when adding hilt (10) rotation and work, when making that carrying out hilt (10) withdraws from the action of main shaft (17), hilt (10) still combines with main shaft (17) securely, and the action that causes forging a knife can't be finished really.
[summary of the invention]
Because the disclosed hilt structure of prior art combines and rotates with main shaft, instability easily rotates, reach thermal expansion and make the situation of forging a knife and being difficult for withdrawing from, the purpose of this utility model is to provide a kind of toolroom machine hilt structure of innovation, to solve the shortcoming of prior art.
The utility model is achieved in that this hilt structure is to comprise a tapering, a tool rest portion and a ring portion, and more comprise one and collapse and adjust structure and be formed on the ring portion surface, and adjoin this tapering; This collapses and adjusts structure is to be groove or hole.When so this hilt was installed on the main shaft, the end face of ring portion and main shaft made hilt can present the state of stable rotation when rotating by putting by this; Again because groove or hole adjustable heat bulging deformation and thermolysis is provided easily withdraw from hilt when therefore helping to forge a knife.
The hilt structure of the toolroom machine that the utility model provides, it has can stable rotation, and is not subjected to the heat expansion effect and the effect that is easy to forge a knife and withdraws from.

Fig. 2 commonly uses the assembly schematic diagram of hilt and main shaft for another.
Fig. 3 is the utility model outside drawing.
Fig. 4 is another outside drawing of the utility model.
Fig. 5 is the utility model and main shaft configuration schematic diagram.
Fig. 6 breaks away from the main shaft schematic diagram for the utility model.
The main element symbol description:
(10) hilt (11) tapering (13) tool rest portion
(15) ring portion (17) main shaft (18) endoporus
(19) end face (22) supplementary plate (24) lock member
(30) hilt (31) tapering (32) tool rest portion
(33) ring portion (40) collapses and adjusts structure (42) groove
(44) hole (50) main shaft (52) endoporus
(54) end face
[specific embodiment]
Please join Fig. 3, hilt (30) is to comprise three to form the position, and it is respectively tapering (31), tool rest portion (32) and ring portion (33).Ring portion (33) be the position between tapering (31) and tool rest portion (32), and link tapering (31) and tool rest portion (32).In other words, tapering (31) and tool rest portion (32) a opposite face in ring portion (33).
One collapses that to adjust structure (40) be the surface that is fabricated on ring portion (33); More specifically, collapsing and adjusting structure (40) is a groove (42), and flute adjoins this tapering (31).
See also Fig. 4, disclosing this another kind of example structure that collapses adjustment structure (40) among the figure is hole (44).Plural number hole (44) is to be distributed in ring portion (33) surface and to adjoin this tapering (31).
See also Fig. 5, the thickness of this ring portion (33) can strengthen, and when making the tapering (31) of hilt (30) place the endoporus (52) of main shaft (50), the end face (54) of main shaft (50) can abut in the surface of ring portion (33).Be with, have bigger contact area between main shaft (50) and the hilt (30), so main shaft (50) can drive hilt (30) high speed rotating stably.
See also Fig. 5, Fig. 6, can produce the heat expansion situation after hilt (30) high speed rotating, but adjust structure (40) but the effect of quick heat radiating because of having on ring portion (33) surface to collapse, so the heat expansion effect can be eliminated fast, in other words, hilt (30) can break away from main shaft (50) easily by forging a knife action.
Be with, the utility model helps ring portion (33) to contact with the end face (54) of main shaft (50) ring portion (33) enlarged in thickness of hilt (30), the stability when improve rotating; Ring portion (33) surface configuration collapses and adjusts structure (40) to improve heat radiation and to eliminate the heat expansion effect, so help to make hilt (30) to break away from main shaft (50) easily under the action of forging a knife again.
Claims (2)
