Abstract
The utility model discloses a spindle end part converting device belonging to the field of numerical control machine tool accessories. The spindle end part converting device is arranged between one end part of a spindle and a chuck, takes the shape of a flat disk, and is characterized in that a positioning hole is formed on an end surface adjacent to the spindle, and a spindle positioning conical surface matched with the conical surface of the spindle is arranged in the center of the end surface; and a positioning block is arranged on an end surface adjacent to the chuck, and a chuck positioning conical surface is arranged in the center of the end surface. Undercut grooves with cylindrical surface structures extend out of the spindle positioning conical surface and the chuck positioning conical surface in the direction of the chuck. Threaded holes capable of fixing the spindle end part converting device with the spindle and the chuck are formed on the two end surfaces of the spindle end part converting device and distributed on the end surfaces in a centrosymmetric manner; and the number of the threaded holes on the same end surface ranges from two to six. The spindle end part converting device provided by the utility model is simple and reliable in structure, and can enable chucks of different specifications to be used on the same numerical control machine tool, thereby reducing the production cost of enterprises and increasing economic benefits.
Description
Technical field
The utility model relates to the Digit Control Machine Tool annex, relates in particular to a kind of spindle nose converting means.
Background technology
In machine industry, numerically controlled lathe is widely used, with the annex that spindle nose is complementary (as oil pressure chuck, oild chuck etc.) of a great variety, the installation form that these annexes that are complementary are connected with main shaft is similar, on same Digit Control Machine Tool, the processing diameter range of workpiece is wider, just need to select the annex that steps up of different size like this according to the part of different size size, but the chuck of different size just needs corresponding spindle nose to match, bring very big inconvenience to production like this, also increased processing cost.For the chuck that makes different size uses, need provide a kind of device that the different size chuck is connected same machine tool chief axis end on same Digit Control Machine Tool.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides with a kind of simple in structure, reliable and stable, the different size chuck can be connected the converting means of spindle nose on same the Digit Control Machine Tool.
Technical scheme: for achieving the above object, spindle nose converting means of the present utility model is arranged between spindle nose and the chuck, this device is oblate plate-like, is provided with locating hole at the end face near main shaft, and the end face center is provided with the main shaft orientational cone-shaped surface that is complementary with the main shaft conical surface; Be provided with locating piece at the end face near chuck, the end face center is provided with the chuck orientational cone-shaped surface.
The grinding of converting means and the main shaft conical surface and the chuck conical surface for convenience is extended with the undercut groove of cylindrical structure along the direction of chuck at described main shaft orientational cone-shaped surface and chuck orientational cone-shaped surface.
Being provided with at two end faces of described converting means can be with this converting means and main shaft and the fixing screwed hole of chuck.Described device screws in screwed hole with screw and fixes be connected the location with spindle nose and chuck after.Described screwed hole center on end face is symmetrically distributed, and screwed hole is 2 ~ 6 in the quantity of same end face.
Beneficial effect: the spindle nose converting means that the utility model provides is simple in structure, reliable, can realize that the different size chuck uses on same Digit Control Machine Tool, reduces enterprise's production cost, has improved economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, this spindle nose converting means is arranged between spindle nose and the chuck, be oblate plate-like, this device left side and main shaft of numerical control machine tool end abutment, right side and chuck adjacency, this device is provided with locating hole 1 and the main shaft orientational cone-shaped surface 2 that is adjacent to the main shaft end face, and the locating piece 3 and the chuck orientational cone-shaped surface 4 that are adjacent to chuck, main shaft orientational cone-shaped surface 2 and main shaft conical surface coupling.Locating hole 1 and locating piece 3 have only 1 respectively, guarantee the uniqueness of spindle nose, spindle nose converting means, chuck three installation site, and can guarantee to install the whole dynamic balancing of back system.Also be extended with the undercut groove 5 of cylindrical structure at main shaft orientational cone-shaped surface 2 and chuck orientational cone-shaped surface 4 along the chuck direction, undercut groove 5 is used to make things convenient for main shaft orientational cone-shaped surface 2 and grinding chuck orientational cone-shaped surface 4.Also being provided with at the contact-making surface of described converting means and spindle nose and chuck can be with this converting means and main shaft and the fixing screwed hole 6 of chuck, and screwed hole center on end face is symmetrically distributed, and screwed hole is 2 ~ 6 in the quantity of same section, decides according to processing request.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
