Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of pentahedron accessory head auto-steering structure, this auto-steering structure can be when guaranteeing the user demand of pentahedron accessory head, make the layout of numerical control device front-end of spindle more compact, reasonable, easy for installation, be conducive to the expansion of numerical control device processed and applied scope.
According to the technical scheme that the utility model provides, a kind of pentahedron accessory head auto-steering structure comprises main blind rivet, blind rivet, splined shaft, draw ring body, gland, bevel gear, key, bearing block, casing and mouse tooth disk; Described main blind rivet and splined shaft are threaded connection composition, wherein main blind rivet by with the coordinating of mainshaft broaching tool gear, accessory head is connected with main shaft; Splined shaft is provided with spline and keyway, and wherein spline coordinates with bevel gear, and keyway coordinates with key when the accessory head turn state; Described mouse tooth disk is connected with casing by screw, and the draw ring body is arranged in the space of mouse tooth disk and casing formation; Blind rivet is connected with the draw ring body by screw thread, and gland is connected with bearing block by screw, and bearing block is connected with casing by screw.
As further improvement of the utility model, described gland is made as interior step shape, and has the gland keyway, and key is arranged in the gland keyway by screw, and the key height is higher than interior shoulder height in gland.
As further improvement of the utility model, described blind rivet adopts four and is distributed on the draw ring body, and its Main Function is to complete the crawl of accessory head under the effect of accessory head pulling device.
Compared with the prior art the utility model has the following advantages:
The utility model directly drives by main shaft and completes the rotating frame mode of accessory head, when guaranteeing the user demand of pentahedron accessory head, make the layout of numerical control device front-end of spindle more compact, reasonable, easy for installation, can effectively complete the rotating mechanical transmission structure of accessory head; Be conducive to the expansion of numerical control device processed and applied scope.
Description of drawings
Structural representation when Fig. 1 the utility model structure is carried out machining.
Fig. 2 the utility model structure control accessory head revolving structure schematic diagram.
The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, comprise main blind rivet 1, blind rivet 2, splined shaft 3, draw ring body 4, the compositions such as gland 5, key 7, bearing block 8, casing 9 and mouse tooth disk 10.
Adopt main blind rivet 1 and splined shaft 3 to be threaded connection the part that coordinates with main shaft in composition the utility model in the utility model, wherein main blind rivet 1 by with the coordinating of mainshaft broaching tool gear, accessory head is connected with main shaft.Splined shaft 3 is designed with splined section and keyway part, and wherein splined section can coordinate with bevel gear 6, and the keyway part coordinates with key 7 when the accessory head turn state, is in released state when accessory head machining state.
Described mouse tooth disk 10 is connected with casing 9 by screw, and draw ring body 4 is arranged in the space of mouse tooth disk 10 and casing 9 formation, and can freely turn round.Blind rivet 2 is connected with draw ring body 4 by screw thread, and blind rivet 2 is evenly equipped with 4 on draw ring body 4, and its Main Function is to complete the crawl of accessory head under the effect of accessory head pulling device.
Described gland 5 is connected with bearing block 8 by screw, and bearing block 8 is connected with casing 9 by screw.Gland 5 is designed to interior step shape, and has keyway, and key 7 is arranged in keyway in gland 5 by screw, and key 7 height are higher than shoulder height in gland 5.
When accessory head was in main shaft machining state, as shown in Figure 1, splined shaft 3 was delivered to main shaft cutting force on bevel gear 6 by spline, and by stage-geared, finally drove the accessory head main shaft and rotate.
As shown in Figure 2, when needs are completed the revolution action of accessory head, at first the accessory head pulling device unclamps with blind rivet 2, due to the active force that has lost the accessory head pulling device, the integral body that gland 5, key 7, bearing block 8, casing 9 and mouse tooth disk 10 form falls, splined shaft 3 is contacted at the A face with gland 5, and bear accessory head weight by the A face.At this moment, key 7 due to higher than shoulder height in gland 5 therefore with splined shaft 3 in keyway be in mated condition.And height of drop is by the clearance control between splined shaft 3 and gland 5, and makes whole lower the backwardness, and blind rivet 2 does not leave and accessory head pulling device cooperation position, guarantees thus accessory head after turning to, and still can install by the accessory head pulling device.
Under this state, splined shaft 3 can be delivered to main shaft cutting force on bevel gear 6 and key 7 simultaneously, and by with the coordinating of key 7, drive the integral body that bearing block 8, casing 9 and mouse tooth disk 10 form and turn round, and drive the accessory head main shaft gyration, complete thus the auto-steering of accessory head.After completing the auto-steering action, the accessory head pulling device by blind rivet 2 crawl accessory heads, carries out follow-up processing work again.
