After clamping, the workpiece and the supporting body can be clamped for cutting at the same time, and the workpiece and the supporting body can be adjusted in the horizontal direction and the vertical direction respectively through a handle and the locating bolts according to needs. According to the burr-free cutting clamp based on the support, the positions of the locating bolts and the clamping blocks can be adjusted in a combined mode according to the shapes and the sizes of the workpiece and the supporting body, so burr-free machining on workpieces of different shapes and sizes can be achieved, the dressing time and cost of the supporting body are saved, and production efficiency is improved.
Description
Technical field
The present invention relates to the clamping field, location in metal cutting field, particularly relate to a kind of few impulse-free robustness clamp for cutting based on supporter.
Background technology
The formation of Metal Cutting Burr is normal, the common phenomenon of metal cutting process one of producing due to the plastic deformation of material, its formation and change directly affect crudy and the working (machining) efficiency of part, also day by day become precision, Ultra-precision Turning and automation and process the significant challenge faced.Show according to correlation study research, in the cutting process of parts, the process time that deburring process spends and processing charges can up to 30% of whole parts machining expense, the precision components such as the parts of such as aircraft engine.For the part of an intermediate complex, its processing charges removing burr also will reach 15%-20%.Removing burr is an additional manufacturing steps having no economic worth, that reduces crudy and the working (machining) efficiency of part.But, if the burr on workpiece can not get effectively controlling or removing, will to bringing great harm.Utilizing supporter method to cut can the formation of effective control of burr in working angles, the harm of reduction burr.But for the part of special shape, supporter method cannot directly apply in working angles, usually needs to repair supporter shape in advance, considerably increases workload.And a suitable fixture can not need additional support trim process, directly realizes the positioning and clamping of workpiece and supporter.
Summary of the invention
For above-mentioned technical problem, the present invention is intended to solve the problems of the technologies described above at least to a certain extent.
The object of this invention is to provide few impulse-free robustness clamp for cutting that a kind of structure is simple, easy to operate, effectively can reduce work pieces process burr.
For achieving the above object, the present invention proposes following technical scheme:
A kind of few impulse-free robustness clamp for cutting based on supporter, comprise clamp base, bolt, supporter, the two ends of described clamp base are relatively horizontally disposed with two fixture blocks for clamping work pieces, described bolt is vertically penetratingly arranged at bottom clamp base, described supporter is arranged at and between the processing end of workpiece and fixture block, after clamping, can holding workpiece and supporter cut, workpiece and supporter can regulate the position of horizontal direction and vertical direction as required respectively by handle and bolt simultaneously.
Further, described fixture block comprise screw mandrel portion, with the clamping head of workpiece close contact, described screw mandrel portion matches with the screw at clamp base two ends, by the position of rotary screw rod portion adjustment clamping head, rotation and adjustable position, can realize the horizontal direction flexible positioning of workpiece and supporter.
Further, described screw mandrel portion runs through one end and is provided with detachable handle, can avoid interference unnecessary in working angles.
Further, the two ends of described clamp base are parallel to each other, and facilitate direct by being applied in working angles after the fixture clamping of planer and milling machine.
Compared to existing technology, advantage of the present invention achieves the workpiece of difformity and size in working angles and the location respectively of supporter and jointly clamps.Particularly, adjustment bolt, can realize the location respectively of workpiece and supporter in the vertical direction.Regulated the horizontal level of fixture block by rotary handle, workpiece and the positioning and clamping of supporter in level can be realized.According to concrete shape and the size of workpiece and supporter, flexible combination regulates the location of horizontal direction and vertical direction, the location of multiple cutting environment can be realized, greatly save cost and the time of supporter finishing, enhance productivity, simultaneously, the present invention is by the method for additional support, improve the support stiffness of workpiece end face, suppress the formation of negative shear zone in working angles, make cutting burr just directly suppressed and be difficult to be formed in working angles.Supporter can be selected flexibly according to different cutting materials, and this just makes the present invention can be applied to the cutting technology of any cutting material.Can suppress the formation of negative burr in working angles completely according to the present invention, greatly reduce the size of the burr formed in working angles, burr height and burr thickness decrease beyond 80%.

Detailed description of the invention
Be described in further detail goal of the invention of the present invention below in conjunction with the drawings and specific embodiments, embodiment can not repeat one by one at this, but therefore embodiments of the present invention are not defined in following examples.
As shown in Figure 1, a kind of few impulse-free robustness clamp for cutting based on supporter, comprise clamp base 1, bolt 6, supporter 5, the two ends of described clamp base 1 are relatively horizontally disposed with two fixture blocks 3 for clamping work pieces 2, described bolt 6 is vertically penetratingly arranged at bottom clamp base 1, described bolt 6 can adopt standard component, can select flexibly according to the shape of workpiece 4 and supporter 5 and relative position and processing request.Described supporter 5 is arranged at and between the processing end of workpiece 2 and fixture block 3, after clamping, can holding workpiece and supporter cut, workpiece and supporter can regulate the position of horizontal direction and vertical direction as required respectively by handle and bolt simultaneously.
Particularly, described fixture block 3 comprise screw mandrel portion 32, with the clamping head 31 of workpiece 2 close contact, described screw mandrel portion 32 matches with the screw at clamp base 1 two ends, the position of clamping head 31 is regulated by rotary screw rod portion 32, rotation and adjustable position, can realize the horizontal direction flexible positioning of workpiece and supporter.
