Abstract
The utility model discloses a combined type spindle head device, belonging to the technical field of accessory equipment of a machine tool. A spindle head is a hollow hole spindle body provided with a center hole and a taper sleeve, one side of the taper sleeve of the spindle body is provided with an end cover of which the size is as the same as that of the outer circle of the spindle body, a hole for connecting and positioning is arranged on the end cover, one end of the spindle body is provided with a hole matched with the spindle body of the spindle head, one end of the spindle head is provided with the taper sleeve, the other end of the spindle head is provided with a center hole of which the size is as the same as that of the center hole of the main spindle body, the spindle head is positioned on the spindle body by a position pin, and the spindle body is in fastening connection with the main shaft body by a connecting bolt. When a taper hole of a spindle is maintained, the spindle head can be withdrawn to be repaired or changed only by disassembling the spindle head, so that the combined type spindle head device is convenient to maintain in a time-saving and labor-saving mode, and the service life of the spindle can be prolonged.
Description
Technical field
The utility model relates to a kind of combined type spindle head device, belongs to lathe auxiliary device technical field.
Background technology
Main shaft is the important composition parts of lathe, in use, and in order to realize different processing requests; Needing often to change cutter processes; Be installed on the lathe because the taper shank of cutter is the taper hole through main shaft, in carrying out the cutter changing process, the handle of a knife of cutter can closely contact with the main shaft taper hole; In the long-term use of lathe, the main shaft taper hole can wear and tear or be damaged because of accident; Because main shaft is overall structure, as repairing, then must the main shaft assembly all be pulled down the taper hole on the main shaft, not only keep in repair into higherly, need recover machine tool accuracy again simultaneously, reduce the service life of main shaft, bring very big inconvenience to maintenance.
Summary of the invention
In order to overcome the technical deficiency of existing main shaft; The utility model provides a kind of combined type spindle head device; This combined type spindle head device can not need be pulled down main shaft assembly integral body, directly main tapping is changed to get final product, and effectively reduces maintenance cost.
The utility model solves the technical scheme that its technical problem adopted: main tapping is the hollow hole axis body that has centre bore and tapered sleeve; Axis body tapered sleeve one side is provided with the end cap identical with the main shaft excircle dimension; End cap is provided with the hole that connects and locate usefulness; One end of main shaft is provided with the hole that matches with the main tapping axis body, and main tapping is that an end is provided with tapered sleeve, and the other end is provided with the centre bore identical with the centre bore of main shaft; Alignment pin is positioned at main tapping on the main shaft, is fastenedly connected through connecting bolt.
The beneficial effect of the utility model is: when spindle taper hole is repaired, only needs main tapping is pulled down, can main tapping be taken out and repair or change, and easy to maintenance, time saving and energy saving, increase main shaft service life.
