Abstract
The utility model relates to a vice for automatic centering machine tool which belongs to the category of metal cutting machine accessories. The utility model has the advantages that the vice is provided with two upper movable vice bodies, and the two movable vice bodies move simultaneously in the process of clamping and unfixing. The vice is operating as that when required, the actions of clamping and unfixing can be accomplished when the propeller shaft is rotated and the two roots of the screw rod are driven by the two pinions on the shaft respectively, and the two movable vice bodies move simultaneously through the impelling of the auxiliary feed screw nut. The median line of the clamped work piece is always aligned to the median line of the vice automatically no matter how thick the work piece is, because the two movable vices bodies of the vice move simultaneously in the process of the clamping and the unfixing.
Description
This utility model belongs to Metal Cutting Machine Tool annex category.Be used for holding workpiece on platen.
The vice chuck that Now has.The jaw and the caliper that all are vice connect firmly together.Another jaw can move with respect to caliper along with the rotation of screw mandrel, reaches the purpose of loosening and clamping.So just a problem is arranged, when the workpiece conversion of clamping, often need to readjust the position of vice on platen.Or travelling table centering again, very time-consuming, for the workpiece that single and mini-batch production is produced, problem is particularly outstanding.
This utility model has increased the function of automatic centering (two movable clamp ports clamp synchronously or loosen) than existing like product, no matter the workpiece thickness that is held how, its center line always aligns with the vice center line automatically, so just can raise the efficiency greatly, reduced need be on workbench the chance of mobile vice or travelling table, leading time shortens, and working strength of workers reduces.
The utility model is made up of base, caliper, moving vice body, screw mandrel and power transmission shaft five major parts.Base and moving vice body and existing vice chuck form basically identical, just many moving vice bodies.The screw mandrel front portion is a trapezoidal thread, two one left-handed, dextrorotation, and pitch is identical, is meshed the purpose of reach synchronous clamping, loosening with guiding nut in two moving vice bodies.The screw mandrel middle part is a gear wheel.Straight-tooth, modulus are 2 millimeters, are meshed with pinion on the power transmission shaft.The screw mandrel rear portion is the axle of a band scrobicular ring, shoulder, is used for the location.Power transmission shaft is considered installation, is divided into left and right two parts, middle connects firmly with two screws 23, and two parts respectively have a pinion to be meshed with gear wheel on the screw mandrel.The left-hand component of power transmission shaft is overhanging, cooperates with spanner to be used for rotating drive shaft, and there is a pair of locator card 24 at overhanging place, is used for axial location.Four major parts all are installed on the caliper.One gear box cover is arranged above the gear wheel.Connect firmly on caliper with screw 8,21.
Description of drawings: accompanying drawing 1,2,3,4 is respectively front view (about except that the power transmission shaft sponson all symmetry), vertical view, left view, bottom view.For the inner body of clear expression, two cutaway views of A-A, B-B have been increased.
The part table is as follows in addition for accompanying drawing:
Numbering title numbering title numbering title
1 power transmission shaft, 11 keys, 21 sunk screws
2 screw mandrels, 12 screws, 22 pump nozzles
3 baffle plates, 13 bearing pins, 23 machines screw with oval countersunk fillister head
4 guiding nuts, 14 calipers, 24 locator cards
5 moving vice body 15 screw pins 25 screws
6 jaws, 16 gear box covers, 26 sunk screws
7 power transmission shaft spreading axles, 17 pads, 27 sunk screws
8 screws, 18 nuts, 28 flat boards
9 pads, 19 bolts, 29 pins
10 bases, 20 sunk screws, 30 screws
Double owing to being equivalent to the movable part of machine tool with vice on the utility model structure, add power transmission shaft and corresponding gear, use the method for vice unanimous on the whole so realize method of the present utility model with realizing machine tool. Screw mandrel adopts round steel to forge rear rough turn shaping, cutting thread, gear hobbing, heat treatment. Power transmission shaft forges rear rough turn and gear hobbing, heat treatment with round steel. The technical process of other parts is identical with vice with machine tool.
Claims (5)
1, automatic centering vice chuck, base 10, caliper 14, moving vice body 5 (two), screw mandrel 2 (two), power transmission shaft 1 and 7 are arranged, it is characterized in that the power transmission shaft that has one to have two pinions, they are meshed with two gear wheels on the two rhizoid bars respectively, and the feed screw nut who forms by screw mandrel and the guiding nut 4 that connects firmly in moving vice body pays and drives two same moved further of moving vice body.
2,, it is characterized in that there is a gear at screw mandrel 2 rear portions as the said automatic centering vice chuck of claim 1.
