Abstract
The invention relates to a tensioning clamping device which comprises a main shaft base, bolts, a main shaft, a flange base, a flange, a tensioning plate, a tensioning bracket, a round end surface, a clamp nut, a thrust ball bearing, a positioning feather key and the like. The device is characterized in that the flange base is fixed on the main shaft base through a bolt; the flange is fixed on the flange base through a bolt, the tensioning plate is mounted on the right side of the flange; the tensioning bracket is arranged on the tensioning plate; the tensioning bracket connects the transversal parts of the round end surface and the tensioning plate as a whole; a workpiece is mounted on the round end surface. Through the adoption of the structure that the thrust ball bearing firmly clamps the workpiece on the tensioning plate driven by the clamping action of the clamp nut, the coaxiality of the workpiece and the main shaft is well ensured, the turning precision is high, the production efficiency is high, and the labor intensity of the worker is greatly reduced.
Description
Technical field
The present invention relates to a kind of bending apparatus, specifically a kind of tensioner clamping device.
Background technology
We know, at present when the workpiece of processing thin-walled shape, due to the clamping workpiece difficulty, the oscillation phenomenon when adding turning, workpiece easily is out of shape in process of production, cause machining accuracy to be difficult to reach requirement, very easily produce endoporus and cylindrical out-of-alignment phenomenon, and roughness is inconsistent, easily produces the cutter phenomenon of calling a taxi, increased production cost, and operating efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of accurate positioning, turning efficient are high, the measured tensioner clamping device of matter.
the present invention solves the problems of the technologies described above the technical scheme of taking: a kind of tensioner clamping device, comprise spindle drum, screw, main shaft, connect the dish seat, connect dish, the tensioner dish, the tensioner support, circular end surface, clamp nut, thrust ball bearing, the location feather key, workpiece, it is characterized in that: the centre bore that connects the dish seat passes main shaft and will connect the dish seat and is fixed by screws on spindle drum, the centre bore that connects dish passes main shaft and will connect to coil to be fixed by screws in and connects on the dish seat, connect the dish right side tensioner dish is installed, be provided with the location feather key between the lateral part of tensioner dish and main shaft, the location feather key is fixed on main shaft, the left side longitudinal component of tensioner dish is provided with the tensioner support, the tensioner support is connected the lateral part of circular end surface and tensioner dish, workpiece is arranged on circular end surface, the right-hand member of tensioner dish is provided with thrust ball bearing, the right side of thrust ball bearing is provided with clamp nut, clamp nut is arranged on the screw thread of main shaft right-hand member.
The present invention is owing to taking above structure, the operator only needs the thin-walled round piece is enclosed within on the circular end surface of tensioner dish, effect by clamp nut promotes the tensioner support, and to drive circular end surface fastening firm and keep good axiality with workpiece, reach the purpose of accurate work piece positioning, improve simultaneously production efficiency and workpiece crudy, reduced workman's labour intensity.
Description of drawings
Fig. 1 is cross-sectional view of the present invention.
Be labeled as in figure: 1. spindle drum, 2. screw, 3. main shaft, 4. connect the dish seat, 5. connects dish, 6. tensioner support, 7. tensioner dish, 8. clamp nut, 9. thrust ball bearing, 10. location feather key, 11. screws, 12. workpiece, 13. circular end surface.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
as shown in Figure 1, the present invention relates to a kind of tensioner clamping device, comprise spindle drum 1, screw 2 and 11, main shaft 3, connect dish seat 4, connect dish 5, tensioner dish 7, tensioner support 6, circular end surface 13, clamp nut 8, thrust ball bearing 9, location feather key 10, workpiece 12, it is characterized in that: the centre bore that connects dish seat 4 passes main shaft 3 and will connect dish seat 4 and is fixed on spindle drum 1 by screw 2, connecing dish 5 centre bore passes main shaft 3 and will connect dish 5 and be fixed on by screw 11 and connect on dish seat 4, connect the dish 5 right sides tensioner dish 7 is installed, 3, the lateral part of tensioner dish 7 and main shaft are provided with location feather key 10, location feather key 10 is fixed on main shaft 3, the left side longitudinal component of tensioner dish 7 is provided with tensioner support 6, tensioner support 6 is connected the lateral part of circular end surface 13 and tensioner dish 7, workpiece 12 is arranged on circular end surface 13, the right-hand member of tensioner dish 7 is provided with thrust ball bearing 9, the right side of thrust ball bearing 9 is provided with clamp nut 8, clamp nut 8 is arranged on the screw thread of main shaft 3 right-hand members.
When the present invention uses, pre-loosening clamp nut is to correct position, the workpiece that processes interior hole dimension is placed on the tensioner dish, then prefastened clamp nut, with hammer tapping workpiece, purpose is that the inner circle end face with workpiece abuts against on the circular end surface that connects dish, and then fastening good clamp nut, begin turning workpiece excircle and end face on request.The present invention changes the clamping workpiece theory, has guaranteed the axiality of inner hole of workpiece and cylindrical, and the turning size is accurate, and is difficult for during turning producing vibration, has improved well the crudy of workpiece, has improved production efficiency.
