Abstract
The utility model discloses a universal crab claw type clamping device comprising a rotating shaft and an adjustable clamping arm, wherein the rotating shaft is adjustable and consists of a rotating shaft, a bearing and a sleeve shaft; an adjusting device capable of enabling the bearing to be fixed is arranged on the sleeve shaft; the rotating shaft is fixedly arranged on a cross-shaped main clamping arm; four clamping arms which extend from the main clamping arm are provided with slotted holes; pressing bolts pass through the slotted holes and are connected with one end of the adjustable clamping arm; and the other end of the adjustable clamping arm is connected with a clamping wheel. Compared with the prior art, the universal crab claw type clamping device has the advantage of compact structure and simple machining. According to the universal crab claw type clamping device disclosed by the utility model, irregular parts with a large aperture can be clamped and machined; and the requirements on machining the parts with different sizes are met. The universal crab claw type clamping device can be used for precisely grinding and polishing the parts with different calibers and shapes.
Description
Technical field
The utility model belongs to a kind of frock clamp, is specifically related to a kind of precise finiss of various bores, Shape Parts, omnipotent crab jaw type clamping device of polishing processing of being used for.
Background technology
The processing mode of common crab jaw type polishing machine is that rocker leans on stylus to drive separator, when separator is not too big, can be inserted in its motion of drive in the separator piggyback connector with thimble as polishing machine.It can only process the part of diameter below 150mm; When the separator diameter is big; For fear of the separator deformation effect machining accuracy that causes owing to the thimble pressurization; Made tripod into square clamper, the crab jaw type clamper is clamped the separator edge by four the rubber wheel or nylon wheels that can rotate, and separator is swung with clamper.The separator that square brandreth drives is more even than the separator grinding that rocker drives, and it is more reasonable that stress point distributes, and can process diameter and be 200 big level crossing.Though but square clamper has had improvement accordingly in order to process bigger level crossing, need make bigger separator, the manufacturing of separator is very difficult and expensive.
The utility model content
In order to overcome the deficiency of the existing crab claw at processing large aperture part; The purpose of the utility model is to provide a kind of processing simple; Can clamping process the large aperture part; Satisfy the omnipotent crab jaw type clamping device of processing different size part needs, can be used for precise finiss, the polishing processing of various bores, Shape Parts.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: this omnipotent crab jaw type clamping device has rotating shaft, adjustable clamp gripping arm; It is characterized in that: said rotating shaft is adjustable rotating shaft, is made up of rotating shaft, bearing and sleeve, on sleeve, is provided with the adjusting device that can make bearing fixing motionless; Rotating shaft is fixed on the cross master clamping limb; Four extended clamping limbs of main clamping limb are provided with long slot bore, and hold-down bolt passes long slot bore and is connected with an end of adjustable clamp gripping arm, and the other end of adjustable clamp gripping arm is connected with the clamping wheel.
Said clamping wheel is nylon swiveling wheel or rubber wheel.
The beneficial effect of the utility model is: 1, use this omnipotent crab jaw type clamping device to be no longer necessary for the separator of processing the part of different size and doing all size; Make fixing clamping limb into scalable, the clamping of rotation can change angle arbitrarily; Help processing the part of all size, thickness, shape; Do not receiving the restriction of separator, part is directly contacted with four moving runners of this patent clamping limb device, perhaps part contact; 2, the stylus that changes rigidity contact is adjustable rotating shaft, and clamping limb also can rotation except moving with rocker, so just makes the movement locus when grinding more complicated, and wearing and tearing, it is even to be easy to.Rubber wheel or nylon swiveling wheel can reduce part stress point by free lifting, have reduced the moment influence in the part movement, are easier to overcome the limit of collapsing.3, ballast can freely add, and is convenient to cooperate the correction aperture.4, part floats, and does not have glued distortion, reduces manufacturing procedure.
Description of drawings
Fig. 1 is the utility model overall structure sketch map.
Fig. 2 is the structural representation that Fig. 1 changes adjustable clamp gripping arm angle.
The specific embodiment
Like Fig. 1, the omnipotent crab jaw type clamping device shown in 2; Having adjustable rotating shaft, cross master clamping limb 2, adjustable clamp gripping arm 4 and pressure holding wheel 5 constitutes; Said adjustable rotating shaft is made up of rotating shaft 2, bearing and sleeve 7, on sleeve 7, is provided with the adjusting device that can make bearing fixing motionless, and adjusting device is for regulating bolt 8; Can not make bearing fixing motionless through regulating bolt 8 if do not want to let clamping limb rotate; Sleeve 7 is fixed on the cross master clamping limb 2, and 2 four extended clamping limbs of main clamping limb are provided with long slot bore 3, and hold-down bolt 6 passes long slot bore 3 and is connected with an end of adjustable clamp gripping arm 4; The other end of adjustable clamp gripping arm 4 is connected with clamping wheel 5, and said clamping wheel is nylon swiveling wheel or rubber wheel.Can change adjustable clamp gripping arm flexible length and angle through regulating hold-down bolt 6, make directly contact part of pressure holding wheel 5, help processing the part of all size, thickness, shape, not receive the restriction of separator.
Claims (2)
1. an omnipotent crab jaw type clamping device has rotating shaft, adjustable clamp gripping arm, it is characterized in that: said rotating shaft is adjustable rotating shaft; Constitute by rotating shaft, bearing and sleeve; On sleeve, be provided with the adjusting device that can make bearing fixing motionless, rotating shaft is fixed on the cross master clamping limb, and four extended clamping limbs of main clamping limb are provided with long slot bore; Hold-down bolt passes long slot bore and is connected with an end of adjustable clamp gripping arm, and the other end of adjustable clamp gripping arm is connected with the clamping wheel.
2. omnipotent crab jaw type clamping device according to claim 1 is characterized in that: said clamping wheel is nylon swiveling wheel or rubber wheel.
