Abstract
A clamp with resetting magnets comprises an installation base, an installation cavity is formed in the installation base, three or more clamping arms are arranged in the installation cavity and are distributed uniformly in the circumferential direction, the heads of the clamping arms extend out of the installation cavity forwards, and the middle parts of the clamping arms are hinged to the installation base. The clamping arm resetting magnets are arranged on the inner sides of the tail parts of the clamping arms and attract the tail parts of the clamping arms to be clamped relatively and reset. By adopting the structure, bevel gear shafts of different diameters can be clamped, the operation is simple, and the application range is wide.
Description
Technical field
The invention belongs to machining tool clamp field, be specifically related to a kind of fixture with reset magnet.
Background technology
Bevel gear is also bevel gear, is widely used in industrial drive apparatus, differential for vehicles, locomotive, boats and ships, power plant, steel mill, railroad track detection etc.Need in bevel gear making process to use fixture to be fixed by bevel gear shaft, then processing and forming is carried out to bevel gear, normally used bevel gear shaft fixture is only a columnar clamping device, therefore the bevel gear shaft for different-diameter needs workman to change the suitable cartridge clamp of internal diameter, not only waste resource, need the cartridge clamp preparing various different model, also waste time and energy, reduce production efficiency, overcome the above problems and become the task of top priority.
Summary of the invention
For solving above technical problem, the invention provides a kind of structure ingenious, applicability is high, can a kind of fixture with reset magnet of firm grip different-diameter bevel gear shaft.
For achieving the above object, technical solution of the present invention is as follows:
A kind of fixture with reset magnet, comprise mount pad (8), be provided with in this mount pad (8) and cavity (81) is installed, at least three clamping limbs (B) are provided with in this installation cavity (81), this clamping limb (B) hoop is uniformly distributed, its main points are: the head of described clamping limb (B) stretches out forward described installation cavity (81) respectively, the middle part of this clamping limb (B) is hinged with mount pad (8) respectively, clamping limb reset magnet (7) is provided with in the inner side of arbitrary described clamping limb (B) afterbody, this clamping limb reset magnet (7) attracts the afterbody of described clamping limb (B) relatively clamp and reset.
Adopt above structure, the afterbody of clamping limb (B) opens by the effect of preposition mechanism, the head of clamping limb (B) closes gradually simultaneously, clamping cone gear shaft, be convenient to the follow-up processing to bevel gear, machine rear clamping limb (B) to reset under the effect of clamping limb reset magnet (7), the diameter of the bevel gear shaft clamped as required due to the large I of clamping limb (B) folding of this structure adjusts flexibly, therefore applied widely, and simple to operate, be easy to left-hand seat.
As preferably: described clamping limb (B) comprises clamping lever (1), and the front portion of this clamping lever (1) is hinged with movable clamping head (2).Adopt above structure, movable clamping head (2) is automatic rotation adjustment angle according to the diameter of the bevel gear shaft of clamping, makes its firm grip bevel gear shaft.
As preferably: the rear portion inwardly protruding of described clamping lever (1), form upset top-joining part (6).Adopt above structure, make clamping limb (B) that the less bevel gear shaft of diameter can be clamped.
As preferably: described movable clamping head (2) comprises two just to the grip block installing plate (21) arranged, be connected with grip block (22) between the inward flange of two these grip block installing plates (21), the front portion of described clamping lever (1) is arranged between two described grip block installing plates (21) by movable rotation-shaft (5).Adopt above structure, be beneficial to movable clamping head (2) clamping cone gear shaft.
As preferably: the clamping end face of described grip block (22) is curved.Adopt above structure, increase the contact area of grip block (22) and bevel gear shaft, and then increasing friction force, be beneficial to clamping cone gear shaft.
As preferably: described grip block installing plate (21) and described grip block (22) integrated molding.Adopt above structure, make movable clamping head (2) structure more firm.
As preferably: the middle part of described clamping limb (B) is hinged in described installation cavity (81) by lever installation shaft (4).Adopt above structure, simple and reliable.
Beneficial effect: a kind of fixture with reset magnet adopting above technical scheme, structure is simply novel, is easy to realize, and by the rotation of clamping limb (B), realizes the clamping to different-diameter bevel gear shaft, simple to operate, and applied widely.
Accompanying drawing explanation

Fig. 2 is the structural representation of clamping limb B of the present invention;
Fig. 3 is the sectional view along A-A place in Fig. 2.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of fixture with reset magnet, comprise mount pad 8, be provided with in this mount pad 8 and cavity 81 is installed, three clamping limb B are provided with in this installation cavity 81, this clamping limb B hoop is uniformly distributed, the head of described clamping limb B stretches out forward described installation cavity 81 respectively, the middle part of this clamping limb B is hinged with mount pad 8 respectively, namely the middle part of described clamping limb B is hinged in described installation cavity 81 by lever installation shaft 4, clamping limb reset magnet 7 is provided with in the inner side of arbitrary described clamping limb B afterbody, this clamping limb reset magnet 7 attracts the afterbody of described clamping limb B relatively clamp and reset.
See Fig. 1 and Fig. 2, described clamping limb B comprises clamping lever 1, and the front portion of this clamping lever 1 is hinged with movable clamping head 2, the rear portion inwardly protruding of described clamping lever 1, forms upset top-joining part 6.
As shown in Figure 3, described movable clamping head 2 comprises two just to the grip block installing plate 21 arranged, grip block 22 is connected with between the inward flange of two these grip block installing plates 21, the clamping end face of described grip block 22 is curved, described grip block installing plate 21 and described grip block 22 integrated molding, the front portion of described clamping lever 1 is arranged between two described grip block installing plates 21 by movable rotation-shaft 5.
During use, the afterbody of clamping limb B opens by the effect of preposition mechanism, clamping lever 1 rotates simultaneously, movable clamping head 2 closes gradually, and grip block 22 and bevel gear shaft fit tightly, clamping cone gear shaft, start machining of bevel gears, after machining, preposition mechanism cancels the effect of the afterbody to clamping limb B, and clamping limb B resets by the effect of clamping limb reset magnet 7.
Finally need explanation; foregoing description is only the preferred embodiments of the present invention, those skilled in the art under enlightenment of the present invention, under the prerequisite without prejudice to present inventive concept and claim; can make like multiple types and representing, such conversion all falls within protection scope of the present invention.
