Abstract
The utility model discloses a protection device capable of reducing friction of a workpiece. The protection device comprises a central ring (1) and a grounding ring (2) positioned inside the central ring (1), wherein the central ring (1) and the grounding ring (2) are concentric rings and are fixedly connected through fixing rods (3); and internal threads are arranged on the inner wall of the central ring (1). Due to the adoption of the structure, the protection device can prevent the workpiece from being damaged and reduce the friction between the workpiece and other contact surfaces.
Description
Technical field
The utility model relates to a kind of protective device, specifically is a kind of protective device that reduces the workpiece friction.
Background technology
Machined into is the part of machining, and machined into 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 on lathe.Lathe is mainly used in and processes axle, dish, overlaps and other have the workpiece of rotary surface, is to use one type of the widest machine tooling in machine-building and the repair factory.In the process of processing, the position of lathe tool remains unchanged, and the whole work-piece 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 bigger friction, is easy to make workpiece impaired like this.
The utility model content
The utility model technical problem to be solved is, provides a kind of and can reduce workpiece impaired a kind of protective device in turning process.
The utility model is that the technical solution problem mainly realizes through following technical scheme: a kind of protective device that reduces the workpiece friction; The ground connection annulus that comprises central circular and be positioned at central circular; Central circular and ground connection annulus are donut; Said central circular and ground connection annulus are fixed together through fixed bar, and the inwall of central circular is provided with internal thread.Central circular is fixed workpiece through internal thread; The ground connection annulus plays the effect of support, has avoided contacting of workpiece and other rubbing surfaces, after workpiece rotates; Central circular and ground connection annulus be correspondingly rotation also, and central circular and ground connection annulus adopt donut to make that rotation is more stable.
Said fixed bar is positioned on the diameter line of ground connection annulus.
The two ends of said fixed bar are separately fixed on the inwall of outer wall and ground connection annulus of central circular.
Said fixed bar has 3 at least.
Said fixed bar equidistantly is distributed on the outer wall of central circular.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model adopts the mode that two donuts are fixedly connected, 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 utility model is simple in structure, and is easy to operate, practical.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the cross sectional representation of the utility model.
Pairing Reference numeral is in the accompanying drawing: 1, central circular, 2, the ground connection annulus, 3, fixed bar, 4, internal thread.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
Like Fig. 1 and shown in Figure 2; The ground connection annulus 2 that the utility model comprises central circular 1 and is positioned at central circular 1; Central circular 1 is a donut with ground connection annulus 2; Said central circular 1 is fixed together through fixed bar 3 with ground connection annulus 2, and the inwall of central circular 1 is provided with internal thread 4.
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 outer wall and ground connection annulus 2 of central circular 1, and fixed bar 3 has 3 at least, and as preferably, the fixed bar of this instance has 3; Fixed bar 3 equidistantly is distributed on the outer wall of central circular 1.
The operation principle of the utility model is: the threaded end of workpiece is screwed in the central circular 1 of the utility model; Fix workpiece, turning adds man-hour, along with the rotation of workpiece; Central circular 1 and ground connection annulus 2 be rotation thereupon also, has avoided contacting of workpiece and other rubbing surfaces.
As stated, then can realize the utility model well.
Claims (5)
1. one kind reduces the protective device that workpiece rubs; The ground connection annulus (2) that comprises central circular (1) and be positioned at central circular (1); Central circular (1) and ground connection annulus (2) are donut; It is characterized in that: said central circular (1) and ground connection annulus (2) are fixed together through fixed bar (3), and the inwall of central circular (1) is provided with internal thread (4).
