Disclosure of Invention
The utility model aims at providing an adjustable tight frock that rises can greatly reduce the vibration that produces man-hour, improves the cutting speed of lathe to greatly improve machining efficiency and part precision.
The purpose of the utility model is realized through the following technical scheme:
an adjustable tensioning tool comprises a tensioning rod 1 and an elastic tensioning sleeve 2, wherein the tensioning rod 1 is provided with a tensioning cone 3, a guide column, a bolt 4 and a hexagonal head 5 in sequence from top to bottom; the upper part of the elastic tensioning sleeve 2 is provided with a conical tensioning part 6 with a notch 9 more than 1, the middle part is provided with a guide cylindrical hole, the lower part is provided with a base 8 with a bolt hole 7, the tensioning cone 3 is arranged in the conical tensioning part 6, the guide cylindrical hole is provided with a guide post, and the bolt 4 is connected with the bolt hole 7 of the base 8.
As a more excellent technical proposal of the utility model, the elastic tensioning sleeve 2 has a conical tensioning part 6 with 3 openings 9 on the upper part.
The beneficial effects are as follows:
the utility model provides a poor problem of machining efficiency low accuracy is added in numerical control of thin wall elbow pipe class part man-hour, compares in the past non-tight formula frock that rises, the utility model provides a vibration that produces in man-hour can greatly be reduced to the frock improves the stock-removing of lathe to greatly improve machining efficiency and part precision.

Detailed Description
For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.
According to the present invention, the following description will be made in detail with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model provides an adjustable tensioning tool, which comprises a tensioning rod 1 and an elastic tensioning sleeve 2, wherein the tensioning rod 1 is provided with a tensioning cone 3, a guide post, a bolt 4 and a hexagon head 5 from top to bottom; the upper part of the elastic tensioning sleeve 2 is provided with a conical tensioning part 6 with a notch 9 more than 1, the middle part is provided with a guide cylindrical hole, the lower part is provided with a base 8 with a bolt hole 7, the tensioning cone 3 is arranged in the conical tensioning part 6, the guide cylindrical hole is provided with a guide post, and the bolt 4 is connected with the bolt hole 7 of the base 8. The upper part of the elastic tensioning sleeve 2 is a conical tensioning part 6 with 3 notches 9.
The utility model discloses a use as follows:
(1) describing the forming parts of a certain high-end vehicle type of the red flag:
the part 3 is an elbow pipe with the wall thickness of 2mm, namely a part to be molded, the inner diameter of the straight pipe is 150mm, the length of the straight pipe is 170mm, the head part is an elbow, and the part is made of pp.
(2) The specific function of the tool is described as follows:
the straight pipe part of the part to be molded is machined and molded through rough turning and finish turning, the semi-finished part is tensioned by an adjustable tensioning tool, and the elbow part is finally molded through a numerical control machine tool.
(3) The tension rod 1 is placed into the elastic tension sleeve 2, the hexagonal head 5 of the tension rod 1 is rotated through a tool such as a sleeve or a wrench, the tension rod 1 is driven by a bolt screwing force to move downwards, so that a guide column of the tension rod 1 enters a guide cylindrical hole of the elastic tension sleeve 2, when a tension cone 3 on the upper portion of the tension rod 1 is just attached to a cone tension portion 6 of the elastic tension sleeve 2, the rotation of the hexagonal head 5 of the tension rod 1 is stopped, and at the moment, the cone tension portion 6 of the elastic tension sleeve 2 is in a loose state. The clamp is completely inserted into an inner hole of a thin-walled part, the hexagonal head 5 at the bottom of the tension rod 1 is continuously rotated, the tension rod 1 continuously moves downwards under the screwing force effect of the threads, the tension cone 3 of the tension rod 1 gradually extrudes the cone tension part 6 of the elastic tension sleeve 2, gaps at 3 positions of the cone tension part 6 can be uniformly increased under extrusion, the excircle of the cone tension part 6 can be gradually increased, small gaps existing between the excircle of the clamp and the inner hole of the part disappear, the excircle of the clamp and the inner hole of the part are gradually contacted, so that the part is subjected to the tensioning force effect of the clamp, and the rotation of the hexagonal head 2 of the tension rod 1 is stopped after the part is tensioned. The clamp and the part are fixed on a universal square box of a machine tool together, the bottom of the part and a clamp base are compressed together by adopting a universal strip-shaped pressing plate, the part is not easy to vibrate when the feeding and back tool amount is increased during numerical control machining, and compared with a clamping mode of clamping a clamping process chuck or a solid stepped cylindrical tool, the machining efficiency and the dimensional precision are greatly improved.
