Description
Technical field
The utility model relates to the process equipment of bearing ring, particularly relates to the clamping device of bearing ring automatic gas cutting machine, belongs to the lathe-use clamp field.
Background technology
Existing machining bearing lasso mostly is that long steel pipe is fixed on the automatic pipe cutter, by automatic pipe cutter steel pipe is cut into a section bearing ring, the shortcoming that this technology exists is: when steel pipe is worked into last 10-20 centimetres, automatic pipe cutter just can't be fixedly clamped to it, therefore automatic pipe cutter just can't be processed remaining steel pipe, can only remaining steel pipe be put on the instrument lathe by manually processing, for example use hacksaw sawed-off, it is many so not only to spend man-hour, labor strength is large, improve production cost, and production efficiency is low, and has affected the production of whole bearing.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, and a kind of reliable clamping is provided, and realizes machining, without the residue steel pipe, enhances productivity, and saving is artificial, the clamping device of the bearing ring automatic gas cutting machine that reduces production costs.
The technical scheme of the clamping device of the utility model bearing ring automatic gas cutting machine is: it is characterized in that: comprise the collet body, one at the collet body is shaped with chuck, chuck contacts with steel pipe inner wall, in chuck, open the tension hole, the right in described tension hole is the round platform hole, the left side is cylindrical hole, be shaped with opening in collet body other end, plug is installed in the opening, the tension plug is installed in the plug, one of the tension plug is shaped with truncated cone-shaped tension head, truncated cone-shaped tension head contacts with the round platform hole, the other end of tension plug is shaped with screw thread, and one of the tension core rod screw thread is passed plug, and the tension core rod screw thread is connected with nut.
The utility model discloses a kind of clamping device of bearing ring automatic gas cutting machine, when automatic pipe cutter during at pipe cutting, first with the outer wall of steel pipe socket at chuck, then clockwise rotate nut with instrument, nut drives the tension plug and is moved to the left, the tension plug drives truncated cone-shaped tension head and is moved to the left, the truncated cone-shaped surface of tension head cooperates with round platform hole inwall, and round platform hole and chuck are expanded outwardly gradually, and chuck expands outwardly a bit of tensioner of carrying out to steel pipe afterbody inwall, make steel pipe obtain clamping, reliable clamping, and obtain surface trimming processing, even steel pipe cuts to only surplus 10-20 centimetres, and chuck is only to a bit of tensioner of carrying out of steel pipe, do not affect the cutting of residue steel pipe, remain steel pipe thereby save existing manually processing by lathe, enhance productivity, save manually, reduce production costs.
The clamping device of the utility model bearing ring automatic gas cutting machine, the inwall of described collet body openings is shaped with draw-in groove, is shaped with corresponding trip at the outer wall of plug, and trip matches with draw-in groove.Had trip and draw-in groove to cooperate, avoided when rotating nut, plug also produces rotation.
Description of drawings
Fig. 1 is the structural representation of the clamping device of the utility model bearing ring automatic gas cutting machine;
Fig. 2 is the schematic side view of collet body;
Fig. 3 is the schematic side view of plug.
The specific embodiment
The utility model relates to a kind of clamping device of bearing ring automatic gas cutting machine, such as Fig. 1-shown in Figure 3, it is characterized in that: comprise collet body 1, one at the collet body is shaped with chuck 11, chuck contacts with steel pipe 2 inwalls, in chuck, open the tension hole, the right in described tension hole is round platform hole 12, the left side is cylindrical hole 13, be shaped with opening 14 in collet body other end, plug 3 is installed in the opening, tension plug 4 is installed in the plug, of tension plug is shaped with truncated cone-shaped tension 41, truncated cone-shaped tension head contacts with round platform hole 12, the other end of tension plug is shaped with screw thread, and one of the tension core rod screw thread is passed plug 3, and the tension core rod screw thread is connected with nut 5.When automatic pipe cutter during at pipe cutting, first steel pipe 2 is enclosed within the outer wall of chuck 11, then clockwise rotate nut 5 with instrument, nut drives tension plug 4 and is moved to the left, the tension plug drives truncated cone-shaped tension 41 and is moved to the left, the truncated cone-shaped surface of tension head cooperates with round platform hole 12 inwalls, round platform hole 12 and chuck 11 are expanded outwardly gradually, chuck expands outwardly a bit of tensioner of carrying out to steel pipe 2 afterbody inwalls, makes steel pipe obtain clamping reliable clamping, and obtain surface trimming processing, even steel pipe 2 cuts to only surplus 10-20 centimetres, and chuck 11 does not affect the cutting of residue steel pipe only to a bit of tensioner of carrying out of steel pipe, thereby save existing manually by lathe processing residue steel pipe, enhance productivity, save manually, reduce production costs.The inwall of described collet body 1 opening 14 is shaped with draw-in groove 15, is shaped with corresponding trip 31 at the outer wall of plug 3, and trip 31 matches with draw-in groove 15.Had trip 31 and draw-in groove 15 to cooperate, avoided when rotating nut 5, plug 3 also produces rotation.
