Abstract
The utility model discloses a special pressing tool for a steel cylinder, which comprises a rotary support, wherein the rotary support is cylindrical, the top of the rotary support is provided with an opening, and the bottom of the rotary support is provided with an annular base; the chuck is fixed at the opening of the rotary support through a bolt, and the tensioning sleeve is arranged inside the rotary support; the clamping device is simple in structure, convenient to operate and high in practicability, and can effectively clamp a cylindrical workpiece to be machined.
Description
Technical Field
The utility model relates to the technical field of spinning auxiliary tools, in particular to a special pressing tool for a steel cylinder.
Background
Thereby the edge of steel barrel needs to reach the turn-up effect to its spinning through the turn-up cutter, and traditional barrel spinning is through the fixed bobbin base of chuck, and the clamping that realizes the barrel is tightly pushed up from bobbin base opposite side simultaneously, however steel barrel itself is because length problem, how stably is fixed in on the spinning equipment to and still can remain stable when rotatory always be a difficult problem that needs to solve.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention provides the following technical solutions: a special pressing tool for a steel cylinder comprises a rotary support, wherein the rotary support is cylindrical, the top of the rotary support is provided with an opening, and the bottom of the rotary support is provided with an annular base; the chuck is fixed at the opening of the rotary support through a bolt, and the tensioning sleeve is arranged inside the rotary support.
Preferably, a limiting hole is formed in the side face of the rotating support close to the annular base.
Preferably, the tensioning sleeve comprises an open end, and the open end is close to the opening of the rotating support.
Preferably, a circle of holes are formed in the sleeve wall of the tensioning sleeve, and each hole is communicated with the opening end.
Preferably, the ejector pin is in a circular truncated cone shape and is tightly attached to the opening end from the inside.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the outer side rotating support and the inner side tensioning sleeve are matched with each other, so that the steel cylinder body is ensured to be fixed between the rotating support and the tensioning sleeve, and the whole cylinder body can be ensured to be stable during rotation of the cylinder body; meanwhile, the round table-shaped thimble is compressed from the opening end, so that a gap between the rotary support and the tensioning sleeve is reduced, the clamping of the cylinder is realized, and the smooth and attractive appearance of the curled part is ensured.
Drawings
FIG. 1 is a cross-sectional view of the present invention;
FIG. 2 is a structural diagram of the tensioning sleeve of the present invention;
in the figure: the device comprises a rotary support 1, an annular base 2, a tensioning sleeve 3, a chuck 4, a limiting hole 5, an opening end 6, a hole 7 and a thimble 8.
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.
Referring to fig. 1-2, the special pressing tool for the steel cylinder comprises a rotary support 1, wherein the rotary support 1 is cylindrical, the top of the rotary support is provided with an opening, and the bottom of the rotary support is provided with an annular base 2; the clamping device is characterized by further comprising a tensioning sleeve 3 and a chuck 4, wherein the chuck 4 is fixed at an opening of the rotating support 1 through a bolt, and the tensioning sleeve 3 is arranged inside the rotating support 1. The barrel is fixed from the inner side and the outer side through the tensioning sleeve 3 and the rotary support 1, the barrel is screwed up through the bolt, and the barrel is clamped from the radial position through the chuck 4 after the barrel is fixed.
In order to fix the tool on the spinning equipment, the side surface of the rotating support 1 is close to the annular base 2, and a limiting hole 5 is formed in the annular base, so that the equipment is favorable for driving the tool to rotate.
In order to reduce the gap of the cylinder and better achieve the compression by internally bracing the tensioning sleeve 3, the tensioning sleeve 3 comprises an open end 6, and the open end 6 is close to the opening of the rotary support 1. A circle of holes 7 are formed in the wall of the tensioning sleeve 3, and each hole 7 is communicated with the opening end 6. Still include thimble 8, thimble 8 is round platform form, hugs closely from inside open end 6, struts the gap of hole 7 and open end 6 intercommunication.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
