Description
Technical field
The utility model relates to motor technologies, more particularly to a kind of skill that the convolution for machine shaft processing is top
Art.
Background technique
In machine shaft manufacturing process, need to carry out turnery processing to shaft blank using lathe, for the ease of lathe
Clamping needs respectively to process a centre bore in the both ends end face of shaft blank, and the inner chamfer of centre bore is substantially at 60 degree or so.
Lathe is usually all top come clamping shaft blank using circling round, as shown in Fig. 2, the common standard convolution of lathe is top
Head 6 be 60 in cone angle cone, when clamping shaft blank 7, the conical head 6 of the convolution item point at lathe both ends is withstood
The centre bore 8 at 7 both ends of shaft blank carrys out fixed rotating shaft blank 7 with this, due to head and the shaft blank end face of convolution item point
The inner chamfer of centre bore essentially coincides, and causes the nearly center hole portion in shaft end face that can not process, can only be in the circumferential surface vehicle of shaft blank
It cuts after processing is completed, is separately processed by later process, this affects the processing efficiency of shaft blank, and due to secondary clamping
Reason, mismachining tolerance is also relatively large, and processing quality is relatively low.
Utility model content
For above-mentioned defect existing in the prior art, the technical problem to be solved by the utility model is to provide a kind of energy
The convolution for machine shaft processing for improving shaft blank processing efficiency and processing quality is top.
In order to solve the above-mentioned technical problem, a kind of convolution top for machine shaft processing provided by the utility model
Point, including top handle, dead head, centre head；The top handle is in the form of a column, and dead head is fixed on the left end of top handle；Its feature
It is:
The centre head is made of left shell of column, middle shell of column, right shell of column, and right shell of column therein is cylindrical, and middle shell of column is in a left side
Thin right thick circular cone shape, left shell of column in cone towards left coniform, and the central axis of left shell of column, middle shell of column and right shell of column
It is overlapped with the central axis of top handle, the right end of right shell of column is fixed on dead head, and the right end of middle shell of column is fixed on right shell of column
Left end, the right end of left shell of column is fixed on the left end of middle shell of column, and the cone angle of left shell of column is greater than the cone angle of middle shell of column.
Further, in the centre head, the cone angle of left shell of column is 2 times of the cone angle of middle shell of column.
Further, in the centre head, the cone angle of left shell of column is 60 degree, and the cone angle of middle shell of column is 30 degree.
Convolution provided by the utility model for machine shaft processing is top, is designed using special construction, centre head
The left shell of column of cone and the inner chamfer of the centre bore of shaft blank end face essentially coincide, using the left shell of column of cone of centre head
To suppress the centre bore of shaft blank end face, and the cone angle due to the cone angle of left shell of column greater than middle shell of column, shaft blank end
The opposite existing standard convolution in space between the nearly center hole portion and shell of column in centre head in face is top amid a sharp increase, to be vehicle
Knife leaves processing space, and the circumferential surface of shaft blank and the processing of end face can be completed in clamped one time, can improve shaft blank and add
Work efficiency rate and processing quality.
Detailed description of the invention
Fig. 1 is the top structural schematic diagram of the convolution for machine shaft processing of the utility model embodiment；
Fig. 2 is the top structural schematic diagram of existing convolution.
Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As shown in Figure 1, a kind of convolution for machine shaft processing provided by the utility model embodiment is top, including
Top handle 1, dead head 2, centre head；The top handle 1 is in the form of a column, and dead head 2 is fixed on the left end of top handle 1；Its feature exists
In:
The centre head is made of left shell of column 5, middle shell of column 4, right shell of column 3, and right shell of column 3 therein is cylindrical, middle shell of column 4
In left thin right thick circular cone shape, left shell of column 5 in cone towards left coniform, and left shell of column 5, middle shell of column 4 and right shell of column 3
Central axis is overlapped with the central axis of top handle 1, and the right end of right shell of column 3 is fixed on dead head 2, the right end of middle shell of column 4
It is fixed on the left end of right shell of column 3, the right end of left shell of column 5 is fixed on the left end of middle shell of column 4, and during the cone angle of left shell of column 5 is greater than
The cone angle of shell of column 4.
In the centre head of the utility model embodiment, the cone angle of left shell of column is 2 times of the cone angle of middle shell of column, left column therein
The cone angle of section is 60 degree, and the cone angle of middle shell of column is 30 degree.
The utility model embodiment is mounted on lathe and uses, and should use in pairs, the motor for clamping turnery processing
Shaft blank, when the machine shaft blank of clamping turnery processing, by shaft blank be placed on two convolutions it is top between, and make two
The top centre head of a convolution tightly suppresses the centre bore at shaft blank both ends respectively, and the clamping of shaft blank, shaft can be completed
After blank is clamping, circle round the left shell of column of top centre head completely into shaft blank end centre bore, after will not influence
Continuous turnery processing, and the cone angle of left shell of column and the inner chamfer of centre bore are almost the same, can be firm fix shaft blank；Top
The middle shell of column of tip generally within shaft blank end centre bore outside (left end of middle shell of column is slightly into centre bore), due to
The cone angle of left shell of column is greater than the cone angle of middle shell of column, the space in the nearly center hole portion and centre head of shaft blank end face between shell of column
Relatively existing standard convolution is top amid a sharp increase, to leave processing space for lathe tool, shaft is can be completed in clamped one time
The circumferential surface of blank and the processing of end face, can improve shaft blank processing efficiency and processing quality.
