Description
Technical Field
The invention belongs to the field of machine tool clamp design, and relates to an internal pressing device suitable for a cylindrical part.
Background
When the cylindric part of processing surface before, generally support cylindric part centre gap with the cylinder, the outside compresses tightly with unadjustable clamp plate, and the part that obtains, the size all can not arrive the position, causes easily that every part location back lower part both sides part has certain deviation, needs an auxiliary adjustable device to carry out the top tight alignment to the part inside.
Disclosure of Invention
The purpose of the invention is as follows: the inner pressing device is suitable for cylindrical parts, so that the cylindrical parts are clamped inside, and the fixing effect is achieved.
The technical scheme is as follows:
an internal compression device for use with a cylindrical part, comprising:
the device comprises a guide block 1, a die body 2, a backing plate 3, a clamping jaw 4, a pressing plate seat 5, a knurled handle 6, a conical head screw 7, a positioning pin 8, a spring 9, a cylindrical pin 10, a limiting block 11 and a screw 12;
the die body 2, the backing plate 3 and the claws 4 are connected together from top to bottom through positioning pins 8; the die body 2, the backing plate 3 and the limiting block 11 are in threaded connection with the pressing plate seat 5 through screws 12, and the limiting block 11 is used for fixing the clamping jaws 4 and keeping sliding fit; the guide block 1 is welded on the die body 2, and the knurled handle 6 and the conical head screw 7 are fixed together through the cylindrical pin 10 to form a propeller capable of being manually adjusted; the conical head screw 7 is screwed into the guide block 1 and keeps sliding fit with the die body 2 and the backing plate 3; the knurled handle 6 is twisted, so that the conical head screw 7 moves downwards, the spring 9 is arranged in the jaw 4, and one end of the spring 9 is fixed by the positioning pin 8.
The downward pressure of the conical head screw 7 causes the spring 9 to compress, moving the jaws 4 outwardly to expand. The opening of the part is attached to the die body 2, and the clamping jaw 4 is abutted to the inner wall of the part cavity, so that the internal part of the part is pressed and aligned.
Has the advantages that:
according to the invention, through the combination of the clamping jaw, the cylindrical pin and the spring, the cylindrical part can be clamped inside, and the fixing effect is achieved.

Detailed Description
As shown in fig. 1, 2, 3 and 4, an internal compression device for a cylindrical part comprises:
the device comprises a guide block 1, a die body 2, a backing plate 3, a clamping jaw 4, a pressing plate seat 5, a knurled handle 6, a conical head screw 7, a positioning pin 8, a spring 9, a cylindrical pin 10, a limiting block 11 and a screw 12;
the spring 9 is placed in the claw 4, and the die body 2, the backing plate 3 and the claw 4 are connected together through the positioning pin 8. The die body 2, the backing plate 3 and the limiting block 11 are in threaded connection with the pressing plate seat 5 through screws 12, and the limiting block 11 is used for fixing the clamping jaws 4 and keeps sliding fit. The guide block 1 is welded on the die body 2, and the knurled handle 6 and the conical head screw 7 are fixed together through the cylindrical pin 10 to form a propeller capable of being manually adjusted. The conical head screw 7 is screwed into the guide block 1 and keeps sliding fit with the die body 2 and the backing plate 3. The knurled handle 6 is twisted, so that the conical head screw 7 moves downwards, the spring 9 is arranged in the jaw 4, and one end of the spring 9 is fixed by the positioning pin 8. The downward pressure of the conical head screw 7 causes the spring 9 to compress, moving the jaws 4 outwardly to expand. The opening of the part is attached to the die body 2, and the clamping jaw 4 is abutted to the inner wall of the part cavity, so that the internal part of the part is pressed and aligned.
