Abstract
The utility model discloses a fastening tool for fastening and pressing a tube-shaped piece. The fastening tool for fastening and pressing the tube-shaped piece comprises a base and a plurality of tool units, wherein the base is used for fixing one end of the tube-shaped piece to be machined, and the tool units are used for fastening and pressing the other end of the tube-shaped piece to be machined. The tool units are sequentially spliced to form a disc, wherein a cavity which can contain the tube-shaped piece to be machined is formed in the center of the disc. A protruding rib is formed on the inner lateral side, close to the center of the cavity, of each tool unit. The protruding ribs are perpendicular to the axis of the tube-shaped piece arranged in the cavity. The fastening tool for fastening and pressing the tube-shaped piece is used for achieving the fastening and pressing connection between the tube-shaped piece and internal parts of the tube-shaped piece, the process is simple, the cost is low, meanwhile, the machining efficiency is high, the product quality is stable, and the profit space of an enterprise is effectively promoted.
Description
Technical field
The utility model relates to a kind of processing tool, relates to specifically a kind of tube-like piece and withholds and use the fastening frock.
Background technology
In the machined field, often have between some tube-like pieces needs and its inner part and realize connecting, method commonly used has laser weld, but laser weld easily changes the performance of product, and equipment is generally expensive, and welding procedure is complicated simultaneously, causes production cost higher.In order to improve this defective, some enterprises begin to adopt the formation of withholding to realize withholding between tube-like piece and its inner body, but there is no at present special crimping equipment.
Summary of the invention
In order to overcome defects, the utility model provides a kind of tube-like piece to withhold and has used the fastening frock, and to realize the connection of withholding between tube-like piece and its inner body, not only technique is simple, and with low cost.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of tube-like piece is withheld and is used the fastening frock, comprise for the base of an end of fixing tube-like piece to be processed and several frocks unit of being used for withholding at the other end of tube-like piece to be processed, these several frock unit is spliced to form the disk that the center has cavity that can accommodating tube-like piece to be processed successively, form a fin on the medial surface of the close described cavity center of each frock unit, and this fin is perpendicular to the axis that is placed in the tube-like piece in described cavity.
As further improvement of the utility model, also comprise a hydraulic press, the upper side of described each frock unit is provided with fixing hole, this each frock unit is fixed on described hydraulic press by described fixing hole, and described hydraulic press can drive the central motion of the disk that each frock unit forms to described several frock unit spliceds.
As further improvement of the utility model, described fin is located at the bottom of the medial surface of each frock unit, and the upper end of the medial surface of this each frock unit is from bottom to up gradually away from described disc centre.
As further improvement of the utility model, described frock unit is 8, and is symmetric.
The beneficial effects of the utility model are: this fastening tool structure is simple, cost; Withhold technique and make the packaging technology optimization of product, production capacity improves; Withhold the change that can not cause properties of product, thus the improving product yield, and working (machining) efficiency improves simultaneously.

The specific embodiment
By reference to the accompanying drawings, the utility model is elaborated, but protection domain of the present utility model is not limited to following embodiment, and the simple equivalence of namely in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, 2, 3, a kind of tube-like piece is withheld and is used the fastening frock, comprise for the base 2 of an end of fixing tube-like piece 1 to be processed and several frocks unit 3 that is used for withholding at the other end of tube-like piece to be processed, these several frock unit is spliced to form the disk that the center has cavity 4 that can accommodating tube-like piece to be processed successively, form a fin 5 on the medial surface of the close described cavity center of each frock unit, and this fin is perpendicular to the axis that is placed in the tube-like piece in described cavity.Fin on several frocks unit splices rear formation one ring-type fin successively, by external force, several frocks unit is pushed respectively like this, several unit push the tube-like piece to be processed of putting in the inner simultaneously, thereby realize that withholding between tube-like piece and its internal part is fixedly connected with.
Preferably, above-mentioned tube-like piece is withheld with the fastening frock and is also comprised a hydraulic press, the upper side of described each frock unit is provided with fixing hole 6, this each frock unit is fixed on described hydraulic press by described fixing hole, and described hydraulic press can drive the central motion of the disk that each frock unit forms to described several frock unit spliceds.
Preferably, described fin is located at the bottom of the medial surface of each frock unit, and the upper end of the medial surface of this each frock unit is from bottom to up gradually away from described disc centre.
Preferably, described frock unit is 8, and is symmetric.
