Description

Self-tensioning movement clamp

Technical Field

The utility model belongs to the technical field of the engine processing equipment, concretely relates to from tensioning core clamp.

Background

Most of the existing core clamps utilize a step round tool, a fastening bolt hole is processed at the excircle of the round tool, a wrench is used for manually fastening the bolt to mount and fasten a rotating workpiece, and a power head rotating drive plate is used for shifting the core clamp to process; the manual clamping device has the defects of complex installation, high labor intensity of manual clamping, large and uneconomical material consumption for regularly replacing bolts and wrenches, unstable safety coefficient of manual clamping force, insecurity and the like.

Disclosure of Invention

The utility model aims at providing a simple structure, simple operation, labour saving and time saving, safety and stability's core presss from both sides.

The purpose of the utility model is realized like this: the utility model provides a press from both sides from tensioning core, it includes annular base member, annular base member front side be provided with adjustable fulcrum, annular base member side seted up U type groove, U type inslot install the eccentric disc, the eccentric disc on the eccentric driving lever of fixedly connected with, annular base member lateral wall on the fixedly connected with pull ring, the free end and the pull ring of eccentric driving lever between be connected through the extension spring.

The two adjustable supporting points are symmetrically distributed.

The center of the U-shaped groove is provided with a pin hole, the eccentric disc is provided with a round hole with the same size as the pin hole, and the eccentric disc is fixed in the U-shaped groove through the matching of the pin shaft, the pin hole and the round hole.

The working principle is as follows:

1. installing a self-tensioning machine core clamp with a specified specification on a product workpiece to be processed;

2. one end of a workpiece of the installed self-tensioning movement clamp faces to the direction of a power driving plate, the center of the workpiece and the center of the power driving plate are positioned on the same straight line and are in rotary connection, an eccentric shifting rod is placed in the middle of a power rod at the edge of the power driving plate, and the rotary direction of the power driving plate is consistent with the clamping direction of the shifting rod of the self-tensioning movement clamp;

3. the power driving plate rotates to drive the power rod to rotate, the power rod presses the eccentric shifting rod of the self-tensioning machine core clamp to rotate clockwise, so that the eccentric disc compresses the workpiece inwards to complete self-locking;

4. when the machining is finished, the workpiece is rotated in the direction opposite to the rotation direction of the power rod, the eccentric shifting rod of the self-tensioning machine core clamp slightly collides with the power rod, and the tension spring rebounds to the self-tensioning machine core clamp shifting rod to finish the self-tensioning of the device.

The utility model has the advantages that: the utility model realizes the self-tensioning of the core clamp to the workpiece through the matching with the power drive plate, is very convenient and practical, effectively reduces the labor intensity of workers, avoids the instability of manual clamping force, greatly increases the safety factor of the core clamp, reduces the use of consumable materials such as bolts and wrenches, reduces the use cost of the core clamp, and greatly improves the working efficiency; generally, the utility model relates to a rationally, have simple structure, simple operation, labour saving and time saving, safety and stability's advantage.

Drawings

Fig. 1 is a schematic structural view of a self-tensioning movement clamp of the present invention.

In the figure: 1. annular base member 2, adjustable fulcrum 3, U type groove 4, round pin axle 5, eccentric disc 6, eccentric driving lever 7, extension spring 8, pull ring.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1

As shown in fig. 1, a from tensioning core clamp, it includes

annular base member

1, 1 front side of annular base member be provided with adjustable fulcrum 2, 1 side of annular base member seted up U type groove 3, U type groove 3 in install eccentric disc 5, eccentric disc 5 on fixedly connected with

eccentric driving lever

6, 1 lateral wall of annular base member on fixedly connected with pull ring 8, free end and pull ring 8 of eccentric driving lever 6 between be connected through extension spring 7, adjustable fulcrum 2 be two, and symmetric distribution, U type groove 3 center seted up the pinhole, eccentric disc 5 on seted up the round hole the same with the pinhole size, eccentric disc 5 is fixed in U type groove 3 through the cooperation of round pin axle 4 with pinhole and round hole.

The utility model discloses a with the cooperation of power driver plate, realize that the core presss from both sides the self-tensioning to the work piece, it is very convenient and practical, the effectual intensity of labour who slows down the workman, avoided the manual clamping dynamics unstable, great increase the factor of safety that the core pressed from both sides, reduced the use of consumptive materials such as bolt and spanner, reduced the use cost that the core pressed from both sides, also make work efficiency obtain very big promotion simultaneously.

Claims
