Abstract
The utility model relates to a kind of steering column tube internal clamp, belongs to motor turning work piece holder field.This internal clamp is made up of expansion core base, latch segment, petal type latch segment is swollen cylinder and hold-down bolt; Expansion core base lower end is provided with positive stop lug boss, and expansion core base top is fixed with the swollen cylinder of petal type latch segment, is movably installed with latch segment in petal type latch segment is swollen cylinder; Latch segment is flexibly connected with expansion core base by hold-down bolt.It is simple, with low cost that this internal clamp has structure, use easy to operate feature, solve car endoporus " monolateral " problem that existing column jecket causes due to column jecket axiality difference own, effectively can ensure the machining accuracy of column jecket Vehicle Processing endoporus, when solving thin-walled parts Vehicle Processing endoporus, clip position is not easily selected, the unmanageable problem of workpiece size, also makes the combination property of steering column be greatly improved.
Description
Technical field
The utility model relates to a kind of steering column tube internal clamp, belongs to motor turning work piece holder field.
Background technology
Increasingly competitive along with automobile industry, improve the quality of products and manufacturing technology level, reduce product cost and become the subject matter that each auto parts and components manufacturer pays close attention at present; thin-walled tubes part is one of many part of motor turning sector application; this type of part is due to himself feature; workpiece wall is thin, rigidity is low, is heated very easily is out of shape by clamping force, cutting force and cutting, and workpiece size is difficult to control.
What the clamping of conventional post pipe part adopted is method with fan-shaped soft pawl holding workpiece cylindrical.Because workpiece tube wall is thinner, fan-shaped soft pawl is difficult to balanced holding workpiece, and suffered chucking power is uneven.This type of processing method is subject to the axiality of workpiece own and appearance and size restriction in addition, steering column tube endoporus circularity is caused to be difficult to ensure the requirement of explained hereafter, " monolateral " phenomenon is there will be and size is difficult to the problems such as control in process, cause defect rate, rework rate higher, and then have influence on column assy combination property.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, practicality is good, to solve existing steering column tube processing endoporus " monolateral " phenomenon and size is difficult to the problems such as controls, and then improve the steering column tube internal clamp of product percent of pass and optimization column assy combination property.
The technical solution of the utility model is:
A kind of steering column tube internal clamp, it is made up of expansion core base, latch segment, petal type latch segment is swollen cylinder and hold-down bolt; It is characterized in that: expansion core base lower end is provided with positive stop lug boss, expansion core base top is fixed with the swollen cylinder of petal type latch segment, is movably installed with latch segment in petal type latch segment is swollen cylinder; Latch segment is provided with bolt hole, is provided with hold-down bolt in bolt hole, latch segment is flexibly connected with expansion core base by hold-down bolt.
The latch segment at described hold-down bolt top is provided with bolt baffle plate, bolt baffle plate is provided with handle hole.
Described latch segment is tapered cylindrical.
Described latch segment diameter is greater than the swollen cylinder diameter of petal type latch segment.
The utility model has the advantage of:
Be arranged on lathe for machining by the lower end of expansion core base during the work of this steering column tube internal clamp, then tubing workpiece to be processed is sleeved on this steering column tube internal clamp, make workpiece bottom fully contact with positive stop lug boss simultaneously; Then rotate and tighten hold-down bolt, make it drive latch segment and expansion core base progressively to close; In this course, because latch segment diameter is greater than the swollen cylinder diameter of petal type latch segment, swollen for petal type latch segment cylinder with in the descending process of hold-down bolt, thus progressively opens by latch segment, realizes the object of workpiece locking thus.It is simple, with low cost that this steering column tube internal clamp has structure, use easy to operate feature, solve car endoporus " monolateral " problem that existing column jecket causes due to column jecket axiality difference own, effectively can ensure the machining accuracy of column jecket Vehicle Processing endoporus, when solving thin-walled parts Vehicle Processing endoporus, clip position is not easily selected, the unmanageable problem of workpiece size, also makes the combination property of steering column be greatly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, positive stop lug boss, 2, expansion core base, 3, latch segment, 4, petal type latch segment is swollen cylinder, 5, hold-down bolt, 6, bolt baffle plate, 7, handle hole.
Detailed description of the invention:
This steering column tube internal clamp is made up of expansion core base 2, latch segment 3, petal type latch segment is swollen cylinder 4 and hold-down bolt 5; Expansion core base 2 lower end is provided with positive stop lug boss 1, and expansion core base 2 top is fixed with the swollen cylinder 4 of petal type latch segment, is movably installed with latch segment 3 in petal type latch segment is swollen cylinder 4.Latch segment 3 is tapered cylindrical; The top diameter of latch segment 3 is greater than petal type latch segment swollen cylinder 4 diameter.
The latch segment 3 of this steering column tube internal clamp is provided with bolt hole, is provided with hold-down bolt 5 in bolt hole, latch segment 3 is flexibly connected with expansion core base 2 by hold-down bolt 5.The latch segment 3 at hold-down bolt 5 top is provided with bolt baffle plate 6, bolt baffle plate 6 is provided with the handle hole 7 for hold-down bolt 5.
During the work of this steering column tube internal clamp, be arranged on lathe for machining by the lower end of expansion core base 2, then workpiece (column jecket class) to be processed is sleeved on this steering column tube internal clamp, make workpiece bottom fully contact with positive stop lug boss 1 simultaneously; Then rotated by handle hole 7 and tighten hold-down bolt 5, make it drive latch segment 3 and expansion core base 2 progressively to close.In this course, because latch segment 3 diameter is greater than petal type latch segment swollen cylinder 4 diameter, latch segment 3 with in the descending process of hold-down bolt 5, thus makes the swollen cylinder 4 of petal type latch segment progressively open, and realizes the object of workpiece locking thus.
It is simple, with low cost that this steering column tube internal clamp has structure, use easy to operate feature, solve car endoporus " monolateral " problem that existing column jecket causes due to column jecket axiality difference own, effectively can ensure the machining accuracy of column jecket Vehicle Processing endoporus, when solving thin-walled tubes part Vehicle Processing endoporus simultaneously, clip position is not easily selected, the unmanageable problem of workpiece size, also makes the combination property of steering column be greatly improved.
