Abstract
The utility model relates to a rotary shaft clamping mechanism for a numerical control double-indexing universal milling head. The rotary shaft clamping mechanism comprises a rotary shaft, a fixing sleeve and a forceps holder retainer, wherein the rotary shaft is in coaxial connection with a spindle box, the fixing sleeve is coaxially sleeved outside the rotary shaft and fixed with a fork head body, and the right end of the fixing sleeve is provided with a first air hole. The forceps holder retainer is coaxially sleeved outside the rotary shaft and fixed with the fixing sleeve, the right end of the forceps holder retainer is provided with a second air hole, the second air hole is communicated with the first air hole, a spring air bag capable of extending in the vertical direction and a clamp ring coaxially arranged outside the rotary shaft are arranged in the forceps holder retainer, the spring air bag is communicated with the second air hole, and the clamp ring abuts against the outer peripheral face of the rotary shaft through the spring air bag. The rotary shaft clamping mechanism shortens the rotary positioning time of a shaft A, improves mechanism safety, accordingly enables the processing precision caused by hydraulic clamping to be improved, and is simple in structure, high in positioning precision, convenient to install, safe and reliable.
Description
Technical field
the utility model relates to the clamp mechanism of electrical-mechanical one, particularly relates to a kind of rotating shaft clamp mechanism that is used for numerical control double universal milling head.
Background technology
are present, and the A axle positioning of rotating of numerical control double universal milling head clamps and is mainly hydraulic clamp, and hydraulic clamp to the forfeiture of rotating shaft clamping force, has directly influenced mechanism's security after losing the energy; The hydraulic clamp reaction is slow, and positioning accuracy is poor, influences the crudy of part; The hydraulic pressure management will be in case leakage will cause greatly pollution.
Summary of the invention
The purpose of
the utility model provides a kind of rotating shaft clamp mechanism that is used for numerical control double universal milling head.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of rotating shaft clamp mechanism that is used for numerical control double universal milling head comprises:
Rotating shaft, described rotating shaft is connected with the main spindle box same axis;
Fixed cover, the coaxial described rotating shaft outside that is set in of described fixed cover fixes with the jaw body, and the right-hand member of described fixed cover offers first pore;
clamp retainer; The coaxial described rotating shaft outside that is set in of described clamp retainer; Fix with described fixed cover; The right-hand member of described clamp retainer offers second pore, and described second pore is connected with first pore, is provided with can in the vertical direction flexible spring air bag, the coaxial outside clamp ring of described rotating shaft that is arranged in the described clamp retainer; Described spring air bag is connected with described second pore, and described clamp ring offsets through the outer peripheral face of spring air bag and described rotating shaft.
preferably, the right part of described rotating shaft is connected with described main spindle box; The left part of described rotating shaft is provided with the dust cap sealing.
preferably, the right-hand member of described fixed cover has step end face, and described first pore is opened on the described step end face.
preferably are provided with O-ring seals between described first pore, second pore.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
the utility model shortens the A axle positioning of rotating time, improves mechanism's security, thereby the machining accuracy problem that causes because of hydraulic clamp is improved, and it is simple in structure, and positioning accuracy is high, and is easy for installation, safe and reliable.
Description of drawings
accompanying drawing 1 is the structural representation of the utility model.
wherein: 1, fixed cover; 2, O-ring seals; 3, clamp retainer; 4, spring air bag; 5, clamp ring; 6, rotating shaft; 7, dust cap; 8, compressed air; 9, A axle; 10, second pore; 11, first pore.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of rotating shaft clamp mechanism that is used for numerical control double universal milling head as shown in the figure comprises:
Rotating shaft 6, the right part of rotating shaft 6 is connected with main spindle box, and the left part is provided with dust cap 7 sealings;
Fixed cover 1, fixed cover 1 coaxial rotating shaft 6 outsides that are set in fix with the jaw body, and the right-hand member of fixed cover 1 has step end face, offers first pore 11 on the step end face;
Below the concrete course of work of present embodiment down of setting forth:
Compressed air 8 is poured through the inside of first pore 11,10 pairs of spring air bags 4 of second pore in
; Spring air bag 4 along continuous straight runs are stretched; Vertical direction shrinks; Relatedly cause reduced distances between the clamp retainer 3 inside and outside side faces, the clamp ring 5 and the outer peripheral face of rotating shaft 6 are broken away from, remove locking rotating shaft 1; When the internal compression air 8 of spring air bag 4 is drained; Spring air bag 4 along continuous straight runs shrink; Vertical direction obtains loosening and stretches and the inner peripheral surface of radial compaction clamp retainer 3 and the axial contact-making surface of outer peripheral face; Make clamp ring 5 push against the outer peripheral face of rotating shaft 6 and in the contact-making surface scope, produce strain, clamp rotating shaft 6 thereupon.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
