The present invention provides a kind of big dynamic braking drum special fixture structure, including chuck seat, finger mountings, claw, master jaw, jaw body, rubber contact and hinge；The bottom of the finger mountings is connected on chuck seat；The claw is articulated with finger mountings by hinge；The claw includes master jaw and jaw body.Claw is dispersed at 12 in jaw body by the present invention to the clamping force of brake drum, and is provided with rubber contact in the contact surface of jaw body and brake drum, makes the distribution of clamping force more uniform, is avoided the clamping thin-wall part pinching deformation the problem of.Clamped one time of the present invention can complete rough turn, finishing processing content, and the rotational angle of claw is limited in 0 30 °, avoids claw excess rotation and influence the efficiency of next clamping, and non-cutting time is few, high in machining efficiency.The clamping adjustability of the present invention is good, versatile, can meet the processing request of multi items.
Description
Technical field
The invention belongs to clamp structure technical field, more particularly to a kind of big dynamic braking drum special fixture structure.
Background technology
With the fast development of automobile industry, the yield of automobile constantly increases, and travel speed improves constantly, to each portion of automobile
The processing request of part part is also constantly improving, and brake drum is an important component in automobile brake, its crudy
Quality directly decides the indices of braking, and can part processing reach design accuracy requirement, directly influence product quality.
At present, the precision of domestic Metal Cutting Machine Tool disclosure satisfy that the processing needs of wheel hub, but the clamping precision of wheel hub and stability
But the machining accuracy and qualification rate of wheel hub are restricted, in order to ensure that brake drum processing can reach every required precision, improves finished product
Qualification rate, it is thought that many method meets requirement on machining accuracy.
Based on above-mentioned, inventor has found, although part producer takes measures in terms of clamping, also functions to certain effect,
It is that clamping uniformity is poor in production in enormous quantities, and precision stability is bad, and piece-holder deforms bad control.
Then, in view of this, improvement is studied for existing structure and missing, there is provided a kind of big dynamic braking drum is special
With clamp structure, to reach the purpose for having more more practical value.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of big dynamic braking drum special fixture structure, big to solve
The problem of clamping uniformity is poor in batch production, and precision stability is bad, and piece-holder deforms bad control.
The purpose and effect of big dynamic braking drum special fixture structure of the invention, are reached by technological means in detail below：
A kind of big dynamic braking drum special fixture structure, including brake drum, the upper face of cylinder, the lower face of cylinder, chuck seat, claw branch
Frame, claw, master jaw, jaw body, rubber contact and hinge；The brake drum includes the upper face of cylinder and the lower face of cylinder；The card
The bottom of pawl support is connected on chuck seat；The claw is articulated with finger mountings by hinge；The claw includes claw
Seat and jaw body.
Further, rotational angle of the claw in finger mountings is 0-30 °.
Further, the claw is ungulate structure.
Further, the jaw body is provided with everywhere altogether on master jaw, and jaw body is symmetrical everywhere and master jaw
Four angles on.
Further, the jaw body is provided with rubber contact with brake drum contact jaw.
Compared with prior art, the present invention has the advantages that：
Claw is dispersed at 12 in jaw body by the present invention to the clamping force of brake drum, and in contact of the jaw body with brake drum
Face is provided with rubber contact, makes the distribution of clamping force more uniform, avoids the clamping thin-wall part pinching deformation the problem of.
Clamped one time of the present invention can complete rough turn, finishing processing content, and the rotational angle of claw is limited in 0-30 °,
Avoid claw excess rotation and influence the efficiency of next clamping, non-cutting time is few, high in machining efficiency.
The installation way of the present invention is coordinated with the upper face of cylinder on brake drum and the lower face of cylinder, clamping adjustability
It is good, it is versatile, the processing request of multi items can be met.
The clamping action of the present invention is simple, reduces unnecessary action, reduces the waste in production, so reduce into
This, improves efficiency, strengthens the competitiveness of product in market.

Embodiment
The present invention is described further below in conjunction with accompanying drawing：
Embodiment：
As shown in accompanying drawing 1 to accompanying drawing 5：
The present invention provides a kind of big dynamic braking drum special fixture structure, including brake drum 11, the upper face of cylinder 12, the lower face of cylinder
13, chuck seat 1, finger mountings 2, claw 3, master jaw 31, jaw body 32, rubber contact 321 and hinge 4；The brake drum 11
Including the upper face of cylinder 12 and the lower face of cylinder 13；The bottom of the finger mountings 2 is connected on chuck seat 1；The claw 3 passes through hinge
Axle 4 is articulated with finger mountings 2；The claw 3 includes master jaw 31 and jaw body 32.
Wherein, rotational angle of the claw 3 in finger mountings 2 is 0-30 °, the restriction to the rotational angle of claw 3, is kept away
Exempt from the excess rotation of claw 3 and influence the efficiency of next clamping.
Wherein, the claw 3 is ungulate structure, and the jaw body 32 is provided with everywhere altogether on master jaw 31, and is blocked everywhere
Corpus unguis 32 it is symmetrical with four angles of master jaw 31 on, by the disperses force of clamping to everywhere in jaw body 32, and jaw body
32 are provided with three altogether, you can grip strength are distributed on 12 points, the grip strength distribution to brake drum 11 is more balanced, keeps away
Exempt from the clamping thin-wall part pinching deformation the problem of.
Wherein, the jaw body 32 is provided with rubber contact 321 with the contact jaw of brake drum 11, further to increase jaw body 32
With the contact area of brake drum 11, and improve frictional force, it is ensured that clamping it is firm, stably.
The specifically used mode of the present embodiment and effect：
In the use of the present invention, it is in upper and lower symmetrically arranged two groups of jaw bodies 32 upper cylinder with brake drum 11 respectively on claw 3
Face 12 and the lower face of cylinder 13 are in contact, and rotational angle of the claw 3 in finger mountings 2 is 0-30 °, with the upper face of cylinder 12 and lower circle
Cylinder 13 adaptively clamps, and is applicable to the clamping of different size model brake drum 11, clamping power point of the claw 3 to brake drum 11
Be scattered at 12 on clamping point, clamping force be uniformly distributed, and in jaw body 32 rubber contact 321 setting, improve frictional force, increase
Big contact area of the jaw body 32 with brake drum 11, makes clamping stable and firm.
Using technical scheme of the present invention, or those skilled in the art is under the inspiration of technical solution of the present invention, if
Similar technical scheme is counted out, and reaches above-mentioned technique effect, is to fall into protection scope of the present invention.
