Abstract
The utility model discloses an anti-skidding pawl, comprising a pawl body. The pawl body comprises a working surface contacted with a workpiece. The anti-skidding pawl is characterized in that the working surface is provided with a rabbet which is detachably provided with an anti-skidding sheet parallel to the working surface. In the anti-skidding pawl, the metal anti-skidding sheet provided with anti-skidding lines and detachably disposed on the inner side of the pawl increases friction between the pawl and the workpiece effectively and improves stability during processing of the workpiece. The anti-skidding pawl has the advantages of simple structure, stable and reliable use, easy replacement and low cost.
Description
Technical field
The utility model relates to a kind of ratchet, in particular for the anti-skidding ratchet of lathe.
Background technology
Lathe is when processing work, usually through ratchet clamping workpiece.Usually be provided with a plurality of slide rails radially on the chuck of lathe, ratchet can move along this slide rail, thereby the workpiece that is placed between the ratchet is carried out clamping.Ratchet is the standard component of lathe manufacturing factory production normally, the common smoother of its inner surface, and this can cause adding man-hour, and workpiece rotates in detent face, thus the precision and the yield rate of influence processing.If the ratchet of customization band anti-skid design, then cost is higher, and easily in long-term use, causes decorative pattern to be polished, and needs often to change, and has further increased cost.
The utility model content
The utility model provides a kind of solution of the above problems, and a kind of simple in structure, anti-skidding ratchet that cost is low is provided.
The technical scheme of the utility model provides a kind of anti-skidding ratchet; It comprises pawl body; Said pawl body comprises the working face that contacts with workpiece, it is characterized in that: said working face is provided with slot, removably is provided with the anti-slide plate parallel with said working face in the said slot.
Preferably, said anti-slide plate is made of metal.
Preferably, said anti-slide plate outer surface is provided with anti-skidding line.
Preferably, said anti-skidding line comprises a plurality of pyramid protuberances that are arranged on said anti-slide plate outer surface.Usually be made up of one 2 * 2 protuberance group 4 protuberances, this protuberance group of a plurality of even settings constitutes said anti-skidding line.
Preferably, the thickness of said anti-slide plate is 1～3mm.
Preferably; Also be provided with thin slice shape pad between said anti-slide plate and the said pawl body; Said pad is removably disposed in the slot of said pawl body, also is provided with slot on the said pad, and said anti-slide plate is removably disposed in the slot of said pad.
A kind of anti-skidding ratchet of the utility model has been owing to installed the anti-slide plate of the metal that detachably has anti-skidding line additional in the inboard of ratchet, thereby effectively increased the frictional force between ratchet and the workpiece, and improved the stability that workpiece adds man-hour.Have simple in structure, use reliable and stable, be convenient to change, low cost and other advantages.

Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 is the front view of anti-slide plate 20.
The specific embodiment
The specific embodiment in the face of the utility model is described in further detail down.
As depicted in figs. 1 and 2, a kind of anti-skidding ratchet of the present invention comprises pawl body 10, and pawl body 10 comprises the curved working face 12 that contacts with workpiece.The working face 12 of ratchet is provided with vertical square slot 14, and the upper end of ratchet slot 14 is concordant with the upper surface of ratchet, forms inlet.Thin slice shape pad 16 is parallel to the direction of working face 12 from the inlet of the top of ratchet slot 14, is inserted into downwards in the ratchet slot 14.Also be provided with slot 18 on the outer surface of pad 16, the upper end of pad slot 18 is concordant with the upper surface of pad 16, forms inlet.The anti-slide plate 20 of thin slice shape metal inserts from the inlet of these pad 16 slots 14.The thickness of anti-slide plate 20 is between 1～3mm, and its outer surface has anti-skidding line.As shown in Figure 3, the anti-skidding line of the utility model first embodiment is to comprise a plurality of pyramid protuberances 22 that are arranged on anti-slide plate 20 outer surfaces.Usually be made up of one 2 * 2 protuberance group 4 protuberances 22, this protuberance of a plurality of even settings constitutes anti-skidding line for 22 groups.This structure can provide frictional force preferably.
Because pad 16 can be changed according to the size of workpiece with anti-slide plate 20; When repeatedly using anti-skidding line wearing and tearing to occur, also can change anti-slide plate 20.Extract during replacing and get final product, therefore simple to operate, maintenance cost is low.
Above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
