Abstract
The invention discloses a protective device for reducing workpiece friction; the protective device comprises a central circular ring (1) and a grounding circular ring (2) which is positioned in the central circular ring (1), wherein the central circular ring (1) and the grounding circular ring (2) are concentric circular rings; the central circular ring (1) and the grounding circular ring (2) are fixedly connected with each other by a fixing rod (3); and an internal thread (4) is arranged on the inner wall of the central circular ring (1). According to the invention, through the adoption of the structure, workpieces can be prevented from being damaged and frictions between the workpieces and other contact surfaces are reduced.
Description
Technical field
The present invention relates to a kind of protective device, specifically a kind of protective device that reduces friction of workpiece.
Background technology
Lathe processing is the part of machining, and lathe processing is mainly carried out turning processing with lathe tool to the workpiece that rotates.Also available drill bit, reamer, reamer, screw tap, screw die and checkering tool etc. are processed accordingly at lathe.Lathe is mainly used in machining shaft, dish, cover and other have the workpiece of rotary surface, is to use a widest class machine tooling in machine-building and the repair factory.In the process of processing, the position of lathe tool remains unchanged, and the whole workpiece chuck that is fixed supports, and is in rotation status, at this moment, if workpiece is direct when fixedly chuck or other contact-making surfaces contact, can produce larger friction, is easy to like this make workpiece impaired.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can reduce workpiece impaired a kind of protective device in turning process.
The present invention is that the technical solution problem is achieved through the following technical solutions: a kind of protective device that reduces friction of workpiece; the ground connection annulus that comprises central circular and be positioned at central circular; central circular and ground connection annulus are donut; described central circular and ground connection annulus are fixed together by fixed bar, are provided with internal thread on the inwall of central circular.Central circular is fixed workpiece by internal thread, the ground connection annulus plays the effect of support, has avoided contacting of workpiece and other rubbing surfaces, after workpiece rotating gets up, central circular and ground connection annulus be correspondingly rotation also, and central circular and ground connection annulus adopt donut so that rotation is more stable.
Described fixed bar is positioned on the diameter line of ground connection annulus.
The two ends of described fixed bar are separately fixed on the inwall of the outer wall of central circular and ground connection annulus.
Described fixed bar has 3 at least.
Described fixed bar equidistantly is distributed on the outer wall of central circular.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention adopts the mode that two donuts are fixedly connected with, and central circular is responsible for fixation workpiece, protection workpiece screw thread, and the ground connection annulus is played a supporting role, and avoids workpiece to contact with other rubbing surfaces, further protects workpiece.
(2) the present invention is simple in structure, and is easy to operate, practical.
Description of drawings
Fig. 1 is front view of the present invention;
Fig. 2 is cross sectional representation of the present invention.
Corresponding Reference numeral is in the accompanying drawing: 1, central circular, 2, the ground connection annulus, 3, fixed bar, 4, internal thread.
The specific embodiment
The present invention is described in further detail below in conjunction with embodiment, but embodiments of the present invention are not limited to this.
Embodiment:
As shown in Figures 1 and 2, the ground connection annulus 2 that the present invention includes central circular 1 and be positioned at central circular 1, central circular 1 and ground connection annulus 2 are donut, and described central circular 1 and ground connection annulus 2 are fixed together by fixed bar 3, are provided with internal thread 4 on the inwall of central circular 1.
Fixed bar 3 is positioned on the diameter line of ground connection annulus 2, and the two ends of fixed bar 3 are separately fixed on the inwall of the outer wall of central circular 1 and ground connection annulus 2, and fixed bar 3 has 3 at least, and as preferably, the fixed bar of this example has 3; Fixed bar 3 equidistantly is distributed on the outer wall of central circular 1.
Operation principle of the present invention is: the threaded end of workpiece is screwed in the central circular 1 of the present invention, fix workpiece, turning adds man-hour, along with the rotation of workpiece, central circular 1 and ground connection annulus 2 be thereupon rotation also, has avoided contacting of workpiece and other rubbing surfaces.
As mentioned above, then can realize well the present invention.
