Description
Technical Field
The utility model belongs to the technical field of the chuck, a light-duty three-jaw chuck is related to.
Background
The chuck generally comprises a chuck body, movable jaws and a jaw driving mechanism. The large chuck is of a disc-shaped structure and is heavy, so that when the size difference of workpieces clamped in sequence is large, the radial moving distance of the clamping jaws is large; the driving mechanism is inserted into the square hole on the side of the chuck body by a wrench manually to rotate for working, and the moving requirement of the clamping jaws can be met only by rotating for a long time. If can alleviate chuck weight to reduce spanner pivoted work load, not only can reduce chuck inertia and energy, reduce operating time moreover, can save the energy greatly and improve work efficiency, more suitable automation equipment operation is used.
Disclosure of Invention
The utility model discloses swift chuck just provides for solving above-mentioned technical problem.
The technical means adopted by the utility model for solving the technical problems is to invent a novel quick chuck, which comprises a chuck body, a clamping jaw and a clamping jaw driving mechanism. The jack catch actuating mechanism includes pinion, big fluted disc and movable block, and the chuck body is Y type structure, and upper portion design has radial groove and support bar sliding fit in every branch of the three branch of chuck body, and the support bar is installed on location strip upper portion, and the location strip is installed on movable block upper portion near chuck body center end portion, and the jack catch is fixed on the support bar dismantled and assembled, and big fluted disc is located the middle part of chuck body and does not have the circle within range. During operation, the novel quick chuck is installed at the position of a workpiece borne by equipment through the installation hole, a proper shifting groove installation clamping jaw is selected on the support bar according to the size of the workpiece, for example, the shifting groove installation clamping jaw close to the center is selected for small workpieces, and the shifting groove installation clamping jaw far away from the center is selected for large workpieces. The spanner is inserted into a square hole on the side of the chuck body to rotate, the small gear is driven to rotate, the small gear is meshed with the bevel gear on the lower side of the large toothed disc to drive the small gear to rotate, the plane threads on the upper side of the large toothed disc are meshed with the threads on the lower side of the movable block to drive the movable block to move radially, then the movable block drives the clamping jaws to move radially to clamp and fix a workpiece through the positioning strips and the supporting strips connected with the movable block, and the weight of the workpiece is transmitted to the chuck body to. The utility model uses the convenient and fast shifting groove for manually installing the jack catch at different positions to solve the problem that the jack catch in the prior art has large radial moving distance and needs to be manually rotated by a wrench for a long time to meet the moving requirement of the jack catch; simultaneously, the Y type design of chuck body and big fluted disc lie in the middle part of chuck body and do not have the circle within range and make novel swift chuck really realize the body light, and the installation is dismantled the convenient saving time of work piece, and is more obvious to the great condition superiority of the work piece size difference of successively centre gripping.
As a further improvement, the upper part of the supporting bar is designed with radially equidistant displacement grooves.
As a further improvement, the distance between the two displacement grooves is designed to be smaller than or equal to the radius of the large fluted disc.
In order to facilitate manufacturing and save cost, the position of the square hole for driving the pinion to rotate is designed in the middle of every two branches of the three branches of the chuck body, and a lengthened square-head wrench can be used for facilitating operation.
In order to keep the novel quick chuck clean and durable, dust strips are arranged between two sides of the supporting strip and the chuck body.
The beneficial effects of the utility model are that through adopting Y type design to the chuck body, alleviate chuck weight greatly to reduce spanner pivoted work load, therefore also reduced during operation chuck inertia and energy, reduce work piece installation operating time moreover, can the energy can be saved greatly and improve work efficiency, more suitable automation equipment operation is used.

Detailed Description
As an implementation mode of the novel quick chuck, the quick chuck comprises a chuck body 7, a clamping jaw 6 and a clamping jaw driving mechanism, wherein the clamping jaw driving mechanism comprises a small gear 1, a large toothed disc 2 and a moving block 3. Chuck body 7 is Y type structure, and the upper portion design has radial groove and 5 sliding fit of support bar in every branch of the three branch of chuck body 7, and support bar 5 is installed on 4 upper portions of location strip with the countersunk head bolt, and location strip 4 is installed on 3 upper portions of movable block with the countersunk head bolt near chuck body 7 center tip, and 6 accessible countersunk head bolts of jack catch are fixed on support bar 5, and big fluted disc 2 is located the no rounding within range in middle part of chuck body 7. The upper part of the supporting bar 5 is designed with five radially equidistant displacement slots 51. The distance between the two displacement grooves 51 is smaller than the radius of the large toothed disc 2. The position of the square hole for driving the pinion 1 to rotate is designed to be in the middle of each two of the three branches of the chuck body 7. Dust strips 8 are arranged between the two sides of the supporting strip 5 and the chuck body 7 and positioned on the chuck body 7. Three symmetrical mounting holes are designed on the chuck body 7, and the roots of the three symmetrical mounting holes, which are close to the three branches of the chuck body, are positioned at the sides of the square holes.
