Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Embodiment 1, refer to fig. 1-4, an expansion tool includes a tool plate 1, a group of T-shaped notches 2 are formed in an array on an upper surface of the tool plate 1, upper ends of two T-shaped notches 2 in the group are communicated and intersected to form a "8" shape, an inner inclined sleeve 3 is fixed inside the T-shaped notch 2, an expansion pull sleeve 4 with a conical inclined surface on an outer side wall is arranged inside the inner inclined sleeve 3 in a matched manner, a pressing portion 5 extends from an edge portion of an upper end surface of the expansion pull sleeve 4, a connecting rod 6 is fixed at the bottom of the expansion pull sleeve 4, a telescopic device 7 is relatively fixed on one side of the tool plate 1, and a telescopic end of the telescopic device 7 is connected with the connecting rod 6.

In this embodiment, the tooling plate 1 is provided with a countersunk hole and is fixedly matched with the inner inclined sleeve 3 through a countersunk screw 12. In the implementation of the embodiment, the telescopic end of the telescopic device 7 extends upwards, the tension sleeve 4 is driven to move upwards through the connecting rod 6, and the tension sleeve 4 and the inner inclined sleeve 3 move relatively due to the fixation of the inner inclined sleeve 3. And because the outer side wall of the tension sleeve 4 is a conical inclined surface, and the inner side wall of the inner inclined sleeve 3 is correspondingly matched with the same inclined surface, the tension sleeve 4 and the inner side wall of the inner inclined sleeve 3 form a certain contact angle. When the tension sleeve 4 moves upwards, the tension sleeve 4 is extruded by the inner wall of the inner inclined sleeve 3, the opening of the tension sleeve 4 shrinks and becomes small, a product 13 is placed at the moment, and the inner diameter of the product 13 is larger than or equal to the outer diameter of the opening of the tension sleeve 4 at the moment.

After being put in, the product 13 is placed on the upper surface of the inner inclined sleeve 3, then the telescopic end of the telescopic device 7 retracts downwards, and the expansion sleeve 4 is driven to move downwards through the connecting rod 6. The opening of the tension sleeve 4 is naturally open, the bottom surface of the press-fitting part 5 at the edge of the opening end face of the tension sleeve 4 is in parallel contact with the product 13 and abuts against the upper surface of the product 13 to form press-fitting of the product 13, and the lossless press-fitting of the product 13 can be ensured by controlling the telescopic stroke of the telescopic device 7.

Further, the connecting rods 6 of a plurality of adjacent tension sleeves 4 are fixed on the connecting block 8, and the connecting block 8 is fixed with the telescopic end of the telescopic device 7. Connecting rod 6 is connected fixedly through pin 11 with connecting block 8, and connecting block 8 is fixed on telescoping device 7's flexible end through the pin, then when telescoping device 7 stretches out and draws back, can drive a plurality of rises and draw cover 4 to carry out the pressure equipment to product 13, and efficiency is higher.

Further, referring to fig. 5, the inner inclined sleeve 3 comprises two semicircular assemblies which are symmetrically arranged and spliced into a complete circle, and the semicircular assemblies are respectively fixed in the T-shaped notches 2 through bolts. Because the inner inclined sleeve 3 is formed by splicing two semicircular assemblies, the inner inclined sleeve 3 can be prevented from being positioned too much when being arranged in the T-shaped groove 2 and fixed.

Further, a vertical support plate 9 is fixed on the bottom surface of the tooling plate 1, and the bottom surface of the support plate 9 is fixed on a horizontal bottom plate 10. The supporting plate 9 is connected with the tooling plate 1 and the bottom plate 10 through bolts, so that the tooling plate 1 is conveniently connected and fixed with production equipment.

Further, the telescopic device 7 comprises a telescopic cylinder fixed on the bottom plate 10. The telescopic cylinder is stable in use, simple in cost and easy to control, and therefore is preferable.

The invention can press-fit a plurality of products at one time, ensures that the products are not damaged by pressure, reduces the working procedures in the production of the products and realizes the automatic press-fitting of the products.

Although the present description is described in terms of embodiments, not every embodiment includes only a single embodiment, and such description is for clarity only, and those skilled in the art should be able to integrate the description as a whole, and the embodiments can be appropriately combined to form other embodiments as will be understood by those skilled in the art.

Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; all changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
