Abstract
A protecting bush for a transmission shaft of a turning lath relates to the technical field of machine tools and comprises bearing blocks, a transmission shaft is arranged between the two bearing blocks, and a moving seat is arranged on the transmission shaft. The protecting bush is characterized in that the two sides of the moving seat are connected with the protecting bush, the protecting bush is sheathed on the transmission shaft and is telescopic and made of rubber, and the transmission shaft is an optical shaft or a wire shaft. According to the protecting bush, the structure is simple, the design is reasonable, the protecting bush is sheathed on the transmission shaft, the abrasion of the transmission shaft as metal filings or other foreign matters fall on the transmission shaft can be prevented, and the protecting bush can be stretched freely along with the moving seat, and can not affect the movement of the moving seat on the transmission shaft.
Description
Technical field:
The utility model relates to the machine-tool technical field, relates in particular to a kind of lathe power transmission shaft sheath.
Background technology:
Lathe is the machine that metal blank is processed into machine parts, and it is a machine of making machine, so be called again " machine-tool " or " toolroom machine ", be called for short lathe traditionally.The method of processing equipment part was a lot of during modern mechanical was made: except that cut; Also have casting, forging, welding, punching press, extruding etc.; In every case belong to the part that required precision is higher and the surface roughness requirement is thinner, generally all need on lathe, finally to process with the method for cutting.
Lathe is mainly with lathe tool the workpiece that rotates to be carried out the lathe that turning is processed, and is to use one type of the widest lathe in machine-building and the repair factory.Lathe has engine lathe and numerically controlled lathe, and numerically controlled lathe all improves a lot with respect to engine lathe machining accuracy and working (machining) efficiency.No matter be engine lathe or numerically controlled lathe, its drive disk assembly all be unable to do without power transmission shaft.In the prior art, the outer power transmission shaft of casing all exposes outside, and smear metal or other foreign material that cutting produces drop on the power transmission shaft easily, and power transmission shaft is caused wearing and tearing, influence the service life of power transmission shaft.
The utility model content:
The utility model technical problem to be solved is to overcome the defective of prior art, provides a kind of foreign matter that prevents to drop on the lathe power transmission shaft sheath on the power transmission shaft.
The utility model technical problem to be solved adopts following technical scheme to realize,
A kind of lathe power transmission shaft sheath comprises bearing block, between the diaxon bearing power transmission shaft is set, and power transmission shaft is provided with and moves seat, it is characterized in that: said mobile seat both sides connect sheath, and sheath is placed on the power transmission shaft.
Said sheath is telescopic rubber and plastic sheath.
Said power transmission shaft is optical axis or silk axle.
The utility model is simple in structure, and is reasonable in design, is with sheath on the power transmission shaft, can prevent that metal fillings or other foreign matter from dropping on the power transmission shaft, causes the wearing and tearing of power transmission shaft, and sheath can freely stretch with moving seat, can not influence and move the motion of seat on power transmission shaft.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of lathe power transmission shaft sheath comprises bearing block 1; Power transmission shaft 2 is set between the diaxon bearing 1, and power transmission shaft 2 is provided with and moves seat 3, moves seat 3 both sides and connects sheath 4; Sheath 4 is placed on the power transmission shaft 2, and sheath 4 is telescopic rubber and plastic sheath, and power transmission shaft 2 is optical axis or silk axle.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
