Description
Technical Field
The utility model relates to a grind hole anchor clamps for bevel gear.
Background
The grinding fixture commonly adopted at present is a chuck provided with three outer clamping feet, the front end of the bevel gear is tightly attached to the inner end surfaces of the three clamping feet to carry out end surface positioning, and the three clamping feet radially contract to clamp the bevel gear to carry out radial positioning; the disadvantages are that: the front end face of the bevel gear is used as a positioning reference, the deformation of a pitch circle of the bevel gear is not corrected, the subsequent pairing grinding cannot completely correct the jumping of a tooth surface, the transmission of a gear pair is not stable, and the noise is very high.
Disclosure of Invention
The utility model aims at the above-mentioned not enough that prior art exists, provide a grind hole anchor clamps, it adopts pitch circle location, plays the correction effect to the deformation of bevel gear pitch circle, and subsequent pairs are lapped the beat that the tooth face can be corrected to the tooth, improve its precision for gear pair transmission is steady, reduces noise by a wide margin, and the clamping is convenient, machining efficiency is high.
In order to achieve the purpose, the utility model discloses a bevel gear grinds hole anchor clamps, including the anchor clamps body that is associative in proper order, fixing base and backup pad, the anchor clamps body all is equipped with the centre bore with the fixing base, the gliding centre bore of locating the anchor clamps body and fixing base of a floating pull rod of its characterized in that, it has the drawing disk to link firmly on the floating pull rod in the fixing base, it is equipped with the spout of three slope to enclose the drawing disk in the fixing base, the gliding respective spout that passes of three depression bars, the one end of depression bar all is equipped with radial draw-in groove, each draw-in groove is arranged in to the outer fringe of drawing disk, the other end of depression bar all sets firmly the clamp plate, the backup pad lies in between the other end of three depression bars in week, several.
When the ball joint pin is used, a workpiece is placed on each ball joint pin, and each ball joint pin is positioned in a tooth groove of the workpiece; pulling the floating pull rod, driving the press rod to move by the pull disc, and pressing the outer conical surface of the workpiece by the press plate; because the ball head pin is positioned in each tooth socket of the workpiece and is in contact with the tooth surface, pitch circle positioning is adopted, the deformation of the pitch circle of the bevel gear is corrected, the subsequent paired grinding can correct the jumping of the tooth surface, the precision is improved, the gear pair is stable in transmission, and the noise is greatly reduced; only the floating pull rod needs to be pulled, so that the clamping is convenient and the processing efficiency is high;
as a further improvement of the utility model, the compression bars are all provided with an axial guide groove at one end, the fixing base is connected with three anti-rotation screws, and the heads of the anti-rotation screws are positioned in the corresponding guide grooves; the anti-rotation screw can prevent the compression bar from rotating and ensure the workpiece to be compressed;
as a further improvement of the utility model, the floating pull rod is internally connected with a bolt through a thread; the floating pull rod is convenient to pull;
to sum up, the utility model discloses a pitch circle location plays the corrective action to the deformation of bevel gear pitch circle, and subsequent to pair can revise beating of flank of tooth of lapping for gear pair transmission is steady, reduces substantially the noise, and the clamping is convenient, machining efficiency is high.
Drawings
Fig. 1 is a front view of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the bevel gear inner hole grinding clamp comprises a clamp body 1, a fixed seat 2 and a support plate 3 which are sequentially connected through bolts, wherein the clamp body 1 and the fixed seat 2 are respectively provided with a central hole, a floating pull rod 4 is slidably arranged in the central holes of the clamp body 1 and the fixed seat 2, a bolt 5 is connected in the floating pull rod 4 through threads, a pull disc 6 is fixedly connected on the floating pull rod 4 in the fixed seat 2, three inclined sliding grooves are arranged in the fixed seat 2 in a manner of surrounding the pull disc 6, three pressure rods 7 slidably penetrate through the respective sliding grooves, one end of each pressure rod 7 is provided with a radial clamping groove 8, the outer edge of each pull disc 6 is arranged in each clamping groove 8, the other end of each pressure rod 7 is fixedly provided with a pressure plate 9, the support plate 3 is circumferentially arranged between the other ends of the three pressure rods 7, and a plurality of ball pins 10 are fixedly; the compression bars 7 are respectively provided with a guide groove 11 with one axial end, the fixed seat 2 is connected with three anti-rotation screws 12, and the heads of the anti-rotation screws 12 are positioned in the corresponding guide grooves 11;
when in use, a workpiece 13 is placed on each ball stud 10, and each ball stud 10 is positioned in a tooth groove of the workpiece 13; the floating pull rod 4 is pulled through the bolt 5, the pull disc 6 drives the compression bar 7 to move and contract inwards, and the pressing plate 9 compresses the outer conical surface of the workpiece 13; because the ball head pin 10 is positioned in each tooth socket of the workpiece 13 and is in contact with the tooth surface, pitch circle positioning is adopted, the deformation of the pitch circle of the bevel gear is corrected, the subsequent paired grinding can correct the jumping of the tooth surface, the precision is improved, the gear pair is stable in transmission, and the noise is greatly reduced; only the floating pull rod 4 needs to be pulled, so that the clamping is convenient and the processing efficiency is high; the rotation-preventing screw 12 can prevent the compression bar 7 from rotating, and ensure the workpiece to be compressed.
