Abstract
The present invention relates to a clamping device for mechanical parts and specifically is a high precision round mouth vice for clamping round and section work piece for fitters and millers. The clamping device is characterized in that the device is provided with two movable vice jaws with an arc mounting surface each. Two mounting grooves, which correspond with the arc surfaces of the movable vice jaws, are arranged on a slider. According to the design of the present invention, the two movable vice jaws are mounted on the movable slider with arc surfaces contacted the movable slider. With the moving of the slider, the vice jaw opens or closes. The outer surface of the vice jaw contacts the inner surface of the slider and the inner arc table surface of the vice jaw contacts the inner groove surface of the slider so that the arc surface contact between the movable vice jaws and the slider is guaranteed. With the change of the work piece form, the movable vice jaw rotates around the arc surfaces and has the ability to clamp work piece with different shapes, thereby clamping round and section work pieces as well as flat parts. The clamping device has the advantages of such as a good clamping stability, a self-positioning ability and a satisfaction of the geometric tolerance of parts etc.
Description
Technical field:
The present invention relates to the machine components clamping device, specifically a kind of solution is milled, the clamping of pincers worker kind circular and the high-precision round-mouth vice of special-shaped workpiece.
Background technology:
We know, vice is the widely used a kind of general facility that are used for holding workpiece of mechanical industry, the vice kind of Shi Yonging in the market, title is extremely various, function and structure also have nothing in common with each other, such as bench vice, K type vice, the vector mode precision vice, air operated vice, hydraulic vice etc., but all vices all have a common ground, they all are to use two plate jaw holder crops, so this class vice can be referred to as parallel jaw, vice is generally by the vice body with dead jaw and screw, the slide block and the rotating threaded shaft that drive the jaw of living are formed, at rotating threaded shaft, the slide block that drives jaw under the effect of screw is close to dead jaw, two jaws clamping work pieces under the effect of leading screw.Its weak point: the one, during the circular and special-shaped working substance of clamping, clamping be two buses of workpiece, the way of contact is two lines contacts, the parts fixation instability if increase the pressure of jaw to working substance, usually can crush part; The 2nd, if circular and special-shaped workpiece has Geometrical Tolerance Principle or when producing in batches, can't correctly locate because of two jaws, can't meet the demands usually, in addition, parallel jaw at all just can't clamping for special-shaped part.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, according to the three-point fix principle, with jaw be designed to be adapted to the circular and special-shaped workpiece of clamping can self-adjusting three jaw versions, provide a kind of can clamping the high-precision round-mouth vice of circular and special-shaped workpiece.
The present invention can reach by following measure:
A kind of high-precision round-mouth vice, be provided with vice body, vice body one end is provided with dead jaw, the other end is provided with screw, and the vice body middle part is provided with the slideway that slide block slides, and rotating threaded shaft cooperates back one end to be connected with slide block with nut, the other end is connected with power set, it is characterized in that being provided with two jaws alive, the installed surface of the jaw of living is an arcwall face, and slide block is provided with two and the corresponding mounting groove of jaw arcwall face of living.
The jaw of living among the present invention is provided with the arc stopper slot, and slide block is provided with positioning pin column, and positioning pin column is in stopper slot, and jaw is spacing in order to live.
The present invention can be provided with positioning pressuring plate above slide block, pressing plate is connected with slide block through bolt, further serving as that the jaw of living carries out spacing.
The present invention's design is installed on the mode of two jaws alive with the arc surface contact on the movable slider, motion realization jaw opening and closing alive along with slide block, the cylindrical of jaw contacts with the interior circle of slide block, table top contacts with the inner groove surface of slide block in the circular arc of jaw alive, thereby the jaw that guarantees to live remains arc surface with slide block and contacts, variation along with the workpiece profile, the jaw of living rotates along arc surface, diversity with holding workpiece, not only be adapted to the clamping of flat-type part, be more suitable for the clamping of circle and special-shaped workpiece, clamping stability is good, can locate automatically, satisfy the advantages such as Geometrical Tolerance Principle of part.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of the slide block and the jaw of living.
Fig. 4 is the A-A profile of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As shown in drawings: a kind of high-precision round-mouth vice, be provided with vice body 1, vice body 1 one ends are provided with dead jaw 2, the other end is provided with screw 3, the vice body middle part is provided with the slideway that slide block 4 slides, rotating threaded shaft 5 cooperates back one end to be connected with slide block 4 with nut 3, and the other end is connected with power set, and is above-mentioned same as the prior art, this does not give unnecessary details, feature of the present invention is to be provided with two jaws 6 alive, and the installed surface of live jaw 6 and slide block 4 is an arcwall face, and slide block 4 is provided with two and the corresponding arc mounting groove of jaw 6 arcwall faces of living, the jaw 6 of living among the present invention is provided with arc stopper slot 7, slide block 4 is provided with positioning pin column 8, and positioning pin column 8 thinks that jaw alive is spacing in stopper slot 7, in addition, the present invention can be provided with positioning pressuring plate 9 above slide block 4, pressing plate 9 is connected with slide block 4 through bolt, further serving as that the jaw of living carries out spacing.
The present invention design is installed on two jaws alives on the movable slider in the mode that the circular arc face contacts, along with slide block The motion jaw opening and closing of realize living, the cylindrical of jaw contact with the inner circle of slide block, the interior table top of the circular arc of the jaw of living and The contact of the inner groove surface of slide block, thus the jaw that guarantees to live remains that with slide block the circular arc face contacts, along with the workpiece profile Change, the jaw of living has the diversity of holding workpiece along the rotation of circular arc face, not only is adapted to the folder of flat-type part Hold, be more suitable for the clamping of circle and abnormal workpieces, clamping stability is good, can automatically locate, and satisfies the morpheme of part The advantages such as tolerance.
