Description

Earring joint class part dead eye bore hole anchor clamps

Technical Field

The utility model belongs to the technical field of aviation part machining, a earring connects class part dead eye bore hole anchor clamps is related to.

Background

The machining of the high-precision bearing hole of the earring joint part is a common problem in the machining process. In the actual machining process, the earring joint part belongs to a non-revolving body part, and a lather cannot machine according to the lathe. And the anchor clamps that use in traditional course of working mainly lean on dabber and clamp plate location, can only be to the clamping of single diameter hole, lead to corresponding anchor clamps dabber specification numerous, do not possess the commonality, the earring joint of clamp plate clamping is easy eccentric drunkenness at random bed rotation in-process simultaneously, and the hole site is easy to incline after the processing, causes the quality risk, probably produces the potential safety hazard even.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an earring connects class part dead eye bore hole anchor clamps relies on numerical control lathe to use as the theme for the non-gyration part hole of lathe work high accuracy earring joint class becomes possible. The clamp has the advantages that through the brand-new design, the influence of centrifugal force generated by asymmetry in the rotation process of the lathe spindle is eliminated to a certain degree, the whole clamp is accurate and reliable, the rigidity is higher, and the processing efficiency and the processing quality of a product can be effectively improved.

Earring connects class part dead eye bore hole anchor clamps includes: the fixture comprises a fixture base body 1, a positioning bushing 2, a threaded buckle 3, a centering mandrel 4, a positioning pin 5 and a guide sleeve 6.

The fixture base body 1 is directly clamped on a lathe chuck to provide stable support for the whole fixture; an inner hole of the positioning bush 2 is matched with an excircle of the end part of the clamp base body 1, and the inner hole and the excircle clamp the machined part together to provide an axial clamping surface for the machined part; the internal thread of the threaded ring buckle 3 is matched with the external thread of the clamp base body 1, and the positioning bush 2 and the processed part are tightly pressed and fixed on the clamp base body 1 by screwing the thread; the centering mandrel 4 is inserted into the clamp base body 1 through the waist-shaped groove of the positioning bush 2 and fixed, so that the bush 2 is prevented from being driven to rotate in the rotation process of the machine tool.

Furthermore, the positioning pin 5 is used when the part to be processed is mounted, and is respectively matched with the guide sleeve 6 and the inner hole of the part to be processed through a stepped shaft, and the position degree of the inner hole of the part to be processed is adjusted to be superposed with the main shaft of the machine tool.

The utility model discloses the advantage:

(1) The utility model discloses based on the lathe uses characteristics, the at utmost be applicable to various types of turning lathe and use processing. The clamping object has strong directivity and high universality, the operation intensity of a traditional boring machine worker is liberated to a certain extent, and the error of the actually processed part inner hole of the clamp can be controlled within 0.02mm or less through verification. The precision grade can reach 6 to 7 grades.

(2) The utility model discloses an adjustable device has been designed to the part in unidimensional, different apertures not, through high-precision conical surface and screw thread latch closure, can effectively process with the part of diameter to different thickness, has realized the multi-purpose theory of one dress, has reduced cost and loss that the instrument was preserved.

(3) The utility model discloses simple structure, the location is reliable to can carry out the improvement and the coordination of size and structure on this basis, make it can be competent in more work occasions, have the value of secondary development.

Detailed Description

The following describes the embodiments of the present invention in detail with reference to the drawings and technical solutions.

Earring connects class part dead eye bore hole anchor clamps includes: the clamp comprises a clamp base body 1, a positioning bush 2, a threaded buckle 3, a centering mandrel 4, a positioning pin 5 and a guide sleeve 6.

As shown in the figure, the specific implementation and operation steps are as follows:

(1) Clamping the fixture base body 1 on a chuck of a lathe, locking and fixing, attaching the processed part to the end face of the fixture base body 1, and installing the positioning bush 2 to clamp the processed part;

(2) Penetrating a positioning pin 5 through a kidney-shaped hole of the positioning bushing 2, and screwing and fixing the positioning pin on the clamp base body 1;

(3) Screwing the threaded ring buckle 3 onto the thread of the clamp base body 1 through the positioning bush 2 until the pressing surface just contacts with the pressing surface of the positioning bush 2;

(4) Inserting the centering mandrel 4 into the guide sleeve 6 along the axial direction through the inner hole of the processed part;

(5) Screwing the thread ring buckle 3 until the processed part is completely clamped;

(6) The centering mandrel 4 is pulled out, and then boring processing can be carried out;

(7) After all the machining work is finished, unscrewing the threaded ring buckle 3, and taking down the machined part;

(8) When the next product is processed, the part to be processed is directly inserted between the clamp base body 1 and the positioning bush 2, and the processing is carried out according to the serial numbers (4) to (7).
