Abstract
The utility model relates to a tension clamping device, which is composed of a spindle seat, screws, a spindle, a flange seat, a flange, a tension disc, a tension support, a circular end surface, a fastening nut, a thrust ball bearing, a location slide key, etc. The tension clamping device is characterized in that the flange seat is fixed on the spindle seat via the screw, the flange is fixed on the flange seat via the screw, the tension disc is installed at the right side of the flange, the tension support is arranged on the tension disc, the circular end surface and the transversal part of the tension disc are integrally connected via the tension support, a workpiece is installed on the circular end surface, the thrust ball bearing is driven via the fastening function of the fastening nut to firmly clamp the workpiece on the tension disc, thus greatly ensuring the coaxiality of the workpiece and the spindle. The tension clamping device is high in turning accuracy, high in production efficiency, and greatly decreased in the labour intensity of workers.
Description
Technical field
The utility model 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, because the clamping workpiece difficulty; Oscillation phenomenon when adding turning, the workpiece easy deformation causes machining accuracy to be difficult to reach requirement in process of production; Very easily produce endoporus and cylindrical out-of-alignment phenomenon, and roughness is inconsistent, is easy to generate the cutter phenomenon of calling a taxi; Increased production cost, and operating efficiency is low.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, and a kind of accurate positioning, high, the measured tensioner clamping device of matter of turning efficient are provided.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of tensioner clamping device; Comprise spindle drum, screw, main shaft, connect the dish seat, connect dish, tensioner dish, tensioner support, circular end surface, clamp nut, thrust ball bearing, location feather key, workpiece; It is characterized in that: the centre bore that connects dish seat passes main shaft and will connect the dish seat and is fixed on the spindle drum through screw, and the centre bore that connects dish passes main shaft and will connect dish and is fixed on through screw and connects on the dish seat, connects 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 the main shaft, and the left side longitudinal component of tensioner dish is provided with the tensioner support, and the tensioner support fuses the lateral part of circular end surface and tensioner dish; Workpiece is installed on the circular end surface; The right-hand member of tensioner dish is provided with thrust ball bearing, and the right side of thrust ball bearing is provided with clamp nut, and clamp nut is installed on the screw thread of main shaft right-hand member.
The utility model is owing to take above structure; The operator only needs the thin-walled round piece is enclosed within on the circular end surface of tensioner dish; Effect through 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, improved production efficiency and workpiece crudy simultaneously, reduced working strength of workers.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Be labeled as among the figure: 1. spindle drum, 2. screw, 3. main shaft 4. connects 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 utility model is done and to be further described:
As shown in Figure 1; The utility model relates to a kind of tensioner clamping device, comprises spindle drum 1, screw 2 and 11, main shaft 3, connects dish seat 4, connects 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 the spindle drum 1 through screw 2; Connecing dish 5 centre bore passes main shaft 3 and will connect dish 5 and be fixed on through screw 11 and connect on the dish seat 4; Connect dish 5 right sides tensioner dish 7 is installed, 3 on the lateral part of tensioner dish 7 and main shaft are provided with location feather key 10, and location feather key 10 is fixed on the main shaft 3; The left side longitudinal component of tensioner dish 7 is provided with tensioner support 6; Tensioner support 6 fuses the lateral part of circular end surface 13 and tensioner dish 7, and workpiece 12 is installed on the circular end surface 13, and 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, and clamp nut 8 is installed on the screw thread of main shaft 3 right-hand members.
When the utility model uses; In advance loosening clamp nut is placed on the tensioner dish prefastened then clamp nut to the workpiece of hole dimension in processing to correct position; With hammer tap workpiece; Purpose is that the interior nose circle face with workpiece abuts against on the circular end surface that connects dish, and fastening then good clamp nut begins turning workpiece excircle and end face on request.The utility model changes the clamping workpiece theory, has guaranteed the axiality of workpiece endoporus and cylindrical, and the turning size is accurate, and is difficult for producing during turning and vibrates, and has improved the crudy of workpiece well, has improved production efficiency.
