The chamfer of hole is handled to the workman on the production line at present uses the instrument of polishing to accomplish mostly, and this kind of method has certain defect: 1) the length of the rod is not adjustable, and the limited strain capacity on space is poor; 2) the end of the rod has no special chamfer head, so that the poured chamfer is not smooth and regular, and even can not meet the requirement. The portable multifunctional automatic chamfering instrument can improve the production efficiency and the product quality.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problems that a portable multifunctional automatic chamfering instrument and a method are provided, the arbitrary adjustment of a chamfering head and the arbitrary adjustment of the length of the chamfering instrument can be met, and the technical problems of poor chamfering quality, limited operation space and the like in the prior art are solved.

In order to solve the above problems, the specific technical scheme of the utility model is as follows:

a portable multifunctional automatic chamfering instrument comprises a handle 1, a compression spring 2, a slide block 3, a screw rod 4 and a screw 5, wherein the compression spring 2, the slide block 3 and the screw rod 4 are arranged in the handle 1; the front end of the screw rod 4 is in threaded connection with a chamfering rod 6, and the end part of the chamfering rod 6 is used for being connected with chamfering heads in various types.

A compression spring 2, a sliding block 3 and a screw rod 4 are sequentially arranged in the handle 1, and the sliding block 3 can slide along the inner wall of the handle 1 under the action of the compression spring; wherein, one end of the compression spring 2 is fixedly connected with the inner surface of one end of the handle 1, and the other end of the handle 1 is provided with a round hole with the diameter larger than that of the chamfering rod. The handle 1 is provided with a through hole for passing the screw 5.

The end part of the chamfering rod 6 penetrates through the circular hole on the end face of the grip 1 and then is in threaded connection with one end of the screw rod 4, and the other end of the screw rod 4 is fixedly connected with the sliding block 3.

The screw rod 4 is provided with a plurality of thread groove structures, after the chamfering rod 6 is connected with the screw rod 4, force is applied into the handle 1 through the chamfering rod 6, the relative position of the chamfering rod 6 and the handle 1 is adjusted through the compression spring 2, and the screw 5 is screwed into the thread groove structures on the screw rod 4 to fix the relative position, so that the hole structure chamfering is completed; after the use, the screw 5 is unscrewed, and the spring force of the compression spring 2 is utilized to drive the sliding block 3 to move and extend out of the chamfering rod 6.

The chamfering rod 6 is provided with a thread at one end and different types of chamfering heads at one end.

A portable multifunctional automatic chamfering instrument and a method thereof are provided, the method comprises the following steps:

1) selecting a proper type of chamfering rod 6;

2) screwing the chamfering rod 6 with the screw rod 4, adjusting the relative position of the chamfering rod 6 and the handle 1, and then fixing the relative position by screwing the screw 5;

3) hole structure chamfering is completed through a portable multifunctional automatic chamfering instrument.

The utility model has the beneficial effects that:

1) this portable multi-functional automatic chamfer appearance can realize that the first free switch of polymorphic type chamfer, chamfer appearance size of a dimension freely change, when improving production efficiency greatly, can also improve the quality of product greatly.

2) The method has the advantages of simple principle, compact structure and high practicability.
