Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to an accurate three -jaw chuck. It includes disk body, jack catch, little bevel gear and big bevel gear, and jack catch and little bevel gear are located the tip and the lateral part of disk body respectively, and big bevel gear is located the inside of disk body, and little bevel gear is connected with big bevel gear meshing, is equipped with welt, regulation hole and adjusting bolt on the jack catch. Pass through welt of extension spring sliding connection of lower part in the inboard of jack catch, the regulation hole is formed with the upper portion of welt jointly to the jack catch to set up conical adjusting bolt in the regulation hole, form wedge fine -tuning. During the use, it is rotatory through the big bevel gear of little bevel gear drive earlier, adjust the jack catch abduction, then insert the pipe fitting between three jack catchs, contract in adjusting the jack catch after that, tentatively push down the pipe wall, prevent the too big damage body of disposable pressure, then the rotation regulation bolt carries out the secondary fine setting to apply suitable pressure, thereby improved the pressurization precision greatly and pressed from both sides the dress quality.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of accurate scroll chuck.
Background technology
Scroll chuck utilizes to be distributed on moving radially of three movable jaws on chuck body, the machine tool accessories of Workpiece clamping and location.Existing scroll chuck structure is simple, clamps coarse, and can only clamp by disposable integral, cannot carry out secondary Local uniqueness, precision is lower, and impact clamps quality and clamps effect.
Utility model content
In order to overcome existing scroll chuck rustic, precision is poor, clamps low-quality deficiency, and the utility model provides a kind of accurate scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of accurate scroll chuck, comprise disk body, claw, bevel pinion and bevel gear wheel, claw and bevel pinion lay respectively at end and the sidepiece of disk body, bevel gear wheel is positioned at the inside of disk body, bevel pinion and bevel gear wheel are connected with a joggle, and claw is provided with liner plate, adjustment hole and adjusting bolt.
According to another embodiment of the present utility model, the bottom comprising liner plate is further plugged on the inner side of claw, is connected with claw by extension spring.
According to another embodiment of the present utility model, the top and the claw that comprise liner plate further form adjustment hole jointly.
According to another embodiment of the present utility model, comprise adjusting bolt further tapered, be threaded in adjustment hole.
The beneficial effects of the utility model are, to be slidably connected one block of liner plate by the extension spring of bottom in the inner side of claw, the top of claw and liner plate forms adjustment hole jointly, and in adjustment hole, arrange the adjusting bolt of taper, form wedge shape micro-adjusting mechanism.During use, first drive bevel gear wheel to rotate by bevel pinion, regulate claw abduction; Then pipe fitting is inserted between three claws; Then regulate claw to inside contract, tentatively push down tube wall, prevent disposable pressure from crossing macrolesion body; Then rotate adjusting bolt, carry out secondary fine setting, to apply suitable pressure, thus substantially increase pressurization precision and clamp quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. disk bodies, 2. claw, 3. bevel pinion, 4. bevel gear wheel, 5. liner plate, 6. adjustment hole, 7. adjusting bolt, 8. extension spring in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of accurate scroll chuck, comprise disk body 1, claw 2, bevel pinion 3 and bevel gear wheel 4, claw 2 and bevel pinion 3 lay respectively at end and the sidepiece of disk body 1, bevel gear wheel 4 is positioned at the inside of disk body 1, bevel pinion 3 and bevel gear wheel 4 are connected with a joggle, and claw 2 is provided with liner plate 5, adjustment hole 6 and adjusting bolt 7.The bottom of liner plate 5 is plugged on the inner side of claw 2, is connected with claw 2 by extension spring 8.The top of liner plate 5 and claw 2 form adjustment hole 6 jointly.Adjusting bolt 7 is tapered, is threaded in adjustment hole 6.
To be slidably connected one block of liner plate 5 by the extension spring 8 of bottom in the inner side of claw 2, claw 2 forms adjustment hole 6 jointly with the top of liner plate 5, and in adjustment hole 6, arrange the adjusting bolt 7 of taper, forms wedge shape micro-adjusting mechanism.During use, first drive bevel gear wheel 4 to rotate by bevel pinion 3, regulate claw 2 abduction; Then pipe fitting is inserted between three claws 2; Then regulate claw 2 to inside contract, tentatively push down tube wall, prevent disposable pressure from crossing macrolesion body; Then rotate adjusting bolt 7, decline extruding liner plate 5, carries out secondary fine setting, to apply suitable pressure, thus substantially increases pressurization precision and clamp quality.
