Abstract
The utility model discloses a machine tool with a protective sleeve. The machine tool comprises a pull rod, a main shaft and a spring chuck, wherein the pull rod is arranged inside the main shaft. The machine tool with the protective sleeve further comprises the protective sleeve, wherein the protective sleeve is hollow, the tail end of the protective sleeve is arranged on the main shaft in a sleeved mode, the head portion of the protective sleeve is in an inner cone shape, and the inner diameter of the head portion of the protective sleeve is greater than the inner diameter of the main shaft. The spring chuck penetrates through and is fixed into the inner portion the protective sleeve, the head portion of the spring chuck is in an outer cone shape, the external taper of the head portion of the spring chuck is matched with the internal taper of the head portion of the protective sleeve, and the rail end of the spring chuck is connected with the pull rod in a threaded mode. The machine tool with the protective sleeve has the advantages of being simple in structure, convenient to manufacture, install and use, and capable of tightly clamping products with large diameters.
Description
Technical field
The utility model relates to a kind of lathe with sheath.
Background technology
At present, existing lathe clamps product by collet, and lathe comprises main shaft, pull bar, and pull bar is positioned at main shaft, and collet is connected in pull bar through spindle thread.There is certain defect in this structure: the maximum grip restricted diameter of collet is in the internal diameter of main shaft, and the maximum gauge of the product that can clamp is at present 40mm, can not clamp the product that diameter is larger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of lathe with sheath, simple in structure, manufactures easy to installly, can clamp large diameter product.
For solving the problems of the technologies described above, the technical solution of the utility model is:
With a lathe for sheath, comprise pull bar, main shaft, collet, described pull bar is positioned at main shaft,
Described lathe also comprises sheath, described sheath hollow, and the end of described sheath is sheathed on main shaft, the head of described sheath and be interior taper, the internal diameter of the head of described sheath is greater than respectively the internal diameter of main shaft and the external diameter of collet,
Described collet passes and is fixed on the inside of sheath, and the head of described collet is outer taper, and the external taper of the head of described collet is consistent with the internal taper of the head of sheath, and the end thread of described collet is connected in pull bar.
Further, being connected between sheath described in the utility model and main shaft is threaded.
During work, sheath is sheathed on to main shaft, collet is sheathed on to pull bar through sheath, the external taper of the internal taper of the head of sheath and the head of collet closely cooperates, product is packed in the head of collet, tension pull bar makes sheath and the collet clamping product that closely cooperates, and machines rear releasing lever, and collet just can unclamp product.
Therefore compared with prior art, the utility model has following beneficial effect:
Because the internal diameter of the head of sheath is greater than the internal diameter of main shaft, so be equivalent to sheath and " expanded " internal diameter of main shaft, the clamping diameter of collet is no longer limited to the external diameter of main shaft internal diameter and collet, therefore can clamp the product that diameter is larger, and simple in structure, manufacture easy to install.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
Be illustrated in figure 1 the embodiment of a kind of lathe with sheath described in the utility model, comprise pull bar 3, main shaft 4, collet 1, pull bar 3 is positioned at main shaft 4, the present embodiment also comprises sheath 2, sheath 2 hollows, the end of sheath 2 is sheathed on main shaft 4, the head of sheath 2 and be interior taper, the internal diameter of the head of sheath 2 is greater than the internal diameter of main shaft 4 and the external diameter of collet, collet 1 passes and is fixed on the inside of sheath 2, the head of collet 1 is outer taper, the external taper of the head of collet 1 is consistent with the internal taper of the head of sheath 2, the end thread of collet 1 is connected in pull bar 3.
Further, in the present embodiment, being connected between sheath 2 and main shaft 4 is threaded, and connects like this better effects if.
The technical scheme above the utility model embodiment being provided is described in detail, applied principle and the embodiment of specific case to the utility model embodiment herein and set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
Claims (2)
