Abstract
The machining center accessory head spindle positioning structure that the present invention relates to is arranged on accessory head and installs faying face position, and its wedge part exceeds accessory head installed surface.When installation accessories head, utilize Chief axis end face to be pushed into by wedge, with accessory head, the flat position of faying face is installed, and the motion of wedge drives the locating slot on alignment pin disengaging accessory head power transmission shaft, simultaneously main shaft run-out key exports keyway with accessory head main shaft and matches, and makes accessory head main shaft energy work in-process heart main shaft drive rotation; When not needing to use accessory head, Chief axis end face and accessory head are installed faying face and are departed from, wedge in this device is under the effect of spring-return power, be returned to and exceed accessory head installed surface position, and alignment pin coordinates with accessory head power transmission shaft locating slot, accessory head main spindle's is fixed, ensure that accessory head its main shaft when next time installs still can remain on the installation site coordinated with main shaft run-out key.Structure of the present invention is simple, rationally, and simple installation; Energy is fixing fitting head main spindle's reasonably, ensure that the Auto-mounting of accessory head, effectively improves the operating efficiency at five-sided machining center.
Description
Technical field
The present invention relates to a kind of machining center accessory head spindle positioning structure, be specifically specially adapted to five-sided machining center needs to use when automatically changing accessory head in process, belongs to frame for movement technical field.
Background technology
Along with the high speed development of China's mechanical industry, especially the development of heavy industry, the demand of the high accuracy process equipments such as five-sided machining center is got more and more, five-sided machining center is a kind of multifunctional numerical control machine grown up on the basis of general-purpose machining center, by automatically changing various attached cutting head, can realize processing the multiaspect of big machinery part, usual clamped one time can complete whole or most manufacturing procedures of big machinery part, thus enhance productivity significantly, comparable general machining center improves work efficiency more than 3 times.Meanwhile, owing to avoiding multiple clamping, eliminate the error that multiple clamping causes, be conducive to improving and ensureing machining accuracy.Five process technologies, not only require that machining center possesses automatic changing main-spindle tool function, and also requirement can change various accessory head, automatically to improve working (machining) efficiency simultaneously.
In five-sided machining process, when carrying out the automatic replacing of accessory head, by the signal feedback of spindle encoder, digital control system can control the position of machining center main shaft cutting moment of torque run-out key, make it be in export with moment of torsion on accessory head the position that keyway matches, complete the automatic replacing of accessory head thus.Before the present invention makes, because the position that main-shaft torque on accessory head cannot be made to export keyway is in a fixed position, the installation of accessory head can only manually be installed, and greatly reduces the working (machining) efficiency of machining center.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of reasonably machining center accessory head spindle positioning structure is provided, make main shaft run-out key slot on accessory head put fixing, and be in the position of matching with main shaft run-out key, machining center can be completed smoothly and change accessory head action.
Machining center accessory head spindle positioning structure of the present invention is mounted in accessory head and installs faying face position, and its wedge part exceeds accessory head installed surface.When installation accessories head, utilize Chief axis end face to be pushed into by wedge, with accessory head, the flat position of faying face is installed, and the motion of wedge drives the locating slot on alignment pin disengaging accessory head power transmission shaft, simultaneously main shaft run-out key exports keyway with accessory head main shaft and matches, and makes accessory head main shaft energy work in-process heart main shaft drive rotation; When not needing to use accessory head, Chief axis end face and accessory head are installed faying face and are departed from, wedge in this device is under the effect of spring-return power, be returned to and exceed accessory head installed surface position, and alignment pin coordinates with accessory head power transmission shaft locating slot, accessory head main spindle's is fixed, ensure that accessory head its main shaft when next time installs still can remain on the installation site coordinated with main shaft run-out key.
Compared with the prior art the present invention has the following advantages: structure of the present invention is simple, rationally, and simple installation; Energy is fixing fitting head main spindle's reasonably, ensure that the Auto-mounting of accessory head, effectively improves the operating efficiency at five-sided machining center.

Detailed description of the invention
Embodiment in composition graphs is further described by the present invention below:
Machining center accessory head spindle positioning structure of the present invention is mainly made up of spring 1, gland 2, alignment pin 3, wedge 4, baffle plate 5.When accessory head is not arranged on Chief axis, as shown in Figure 1, accessory head casing 7 has alignment pin installing hole and wedge installing hole, and both are in mutual plumbness; Respectively as shown in Figure 3, Figure 4, alignment pin 3 middle part has the inclined-plane coordinated with wedge 4 for alignment pin 3 and wedge 4 profile; Alignment pin 3 is arranged in the alignment pin installing hole on accessory head casing 7, and its rear end is provided with spring 1, and gland 2 is arranged on accessory head casing 7, and Compress Spring 1; In spring 1 resilient force, the wedge part of alignment pin 3 front end coordinates with locating slot on axle 6, and makes axle 6 be fixed on current state; Wedge 4 is arranged in the wedge installing hole on accessory head casing 7, and coordinates with alignment pin 3, and its fit angle must be greater than Self-locking angle; Baffle plate 5 is arranged on accessory head casing 7, controls the height of rear end face higher than accessory head installed surface of wedge 4, also just controls the movement travel of wedge 4 and alignment pin 3.In this case, accessory head axis 6 is in stationary state, must not arbitrarily rotate, and the accessory head main shaft be connected with axle 6 also must not rotate, and this guarantees accessory head is not having under the state of installing, and accessory head main shaft is in a fixed position.
Figure 2 shows that accessory head installment state, when accessory head needs to be arranged on machining center Chief axis, in the process that work in-process heart main shaft end face coordinates with accessory head casing 7 end contact, wedge 4 is promoted left, under the effect on inclined-plane, alignment pin 3 moves upward, and while Compress Spring 1, alignment pin 3 front end and axle 6 depart from; Meanwhile, on machining center, main shaft output driving key and axle 6 rear end export driving key slot fit, and accessory head main axis will be synchronous with process equipment main axis, accessory head installation.After accessory head uses, controlled by spindle encoder, accessory head axis 6 is gone to and installs front identical position, after accessory head departs from main shaft end face, accessory head returns back to state shown in Fig. 1.
The present invention is installed by the cooperation that spring 1, gland 2, alignment pin 3, wedge 4, baffle plate 5 are mutual, when the non-installment state of accessory head, the position being fixed on and matching with main shaft run-out key is put in main shaft run-out key slot on accessory head axis 6, is convenient to the installation of accessory head; And after accessory head uses, controlled by spindle encoder, accessory head axis 6 is returned to initial position, be convenient to the smooth installation of next accessory head, effectively ensure that operating efficiency.
