Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of novel clamp for processing thin-walled cylinder part, belong to Machining Technology field.
Background technology
Along with the fast development of modern mechanical processing, Machining Technology have also been obtained fast development.In machining, as the device of fixing processing object, the application of fixture is extremely important.Elongated thin cylinder part is the part that in actual production, Application comparison is many, belongs to more difficult processing parts, and whether the location clamping of such part in machining be reasonable, decides the size of part deformation, directly have influence on the machining accuracy of part.Such elongated thin cylinder part length is longer, wall thickness is thin, poor rigidity, when turnery processing, is vulnerable to the impact of the factors such as the thermal deformation that clamping, gravity, vibration and cutting produce, and is difficult to the machining accuracy and the instructions for use that ensure workpiece.
At present, there is many deficiencies in the conventional clamp for processing slim thin cylinder part, main manifestations is: 1) positioning datum and design basis disunity, is difficult to the perpendicularity ensureing end face and axis; 2) clamping workpiece is wasted time and energy, and affects production efficiency; 3) workpiece easily deforms and trembles in cutting process, thus affects machining accuracy and the instructions for use of workpiece; 4) workpiece is in process, and its surface easily produces and scratches phenomenon.
Summary of the invention
For the demand, the invention provides a kind of novel clamp for processing thin-walled cylinder part, this novel clamp manufacture is simple, easy to operate, its strong point is many, area is large, there is excellent tensioner performance, can prevent part from deforming in process and trembleing, effectively ensure that machining accuracy and the instructions for use of part.
The present invention is a kind of novel clamp for processing thin-walled cylinder part, described novel clamp comprises mandrel, location-plate, tube connector, spacer, tensioner element and pressing plate, described location-plate is fixed on mandrel one end, described tube connector to be fixed on mandrel and to be close to location-plate, and described spacer, tensioner element and pressing plate are arranged on tube connector respectively.
In a preferred embodiment of the present invention, described spacer and tensioner element matched in clearance, and be divided into many groups and be arranged on tube connector, wherein, first group of spacer and location-plate close contact.
In a preferred embodiment of the present invention, described tensioner element is divided into many groups and is arranged on tube connector, its last group with pressing plate close contact.
In a preferred embodiment of the present invention, hold down gag has been installed in described pressing plate side, and this hold down gag is compressed pressing plate by adjusting lock nut.
In a preferred embodiment of the present invention, described tensioner element have employed polyurethane rubber, and this polyurethane rubber, under the compression of pressing plate, elastic deformation occurs, and produces radial forces, and then tensioner, support part.
Present invention is disclosed a kind of novel clamp for processing thin-walled cylinder part, this novel clamp manufacture is simple, easy to operate, its strong point is many, area is large, there is excellent tensioner performance, can prevent part from deforming in process and trembleing, effectively ensure that machining accuracy and the instructions for use of part.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the embodiment of the present invention for the novel clamp of processing thin-walled cylinder part;
In accompanying drawing, the mark of each parts is as follows: 1, mandrel, 2, location-plate, 3, tube connector, 4, tensioner element, 5, spacer, 6, pressing plate, 7, locking nut, 8, thin cylinder part.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the structural representation of the embodiment of the present invention for the novel clamp of processing thin-walled cylinder part; This novel clamp comprises mandrel 1, location-plate 2, tube connector 3, spacer 5, tensioner element 4 and pressing plate 6, described location-plate 2 is fixed on mandrel 1 one end, described tube connector 3 to be fixed on mandrel 1 and to be close to location-plate 2, and described spacer 5, tensioner element 4 and pressing plate 6 are arranged on tube connector 3 respectively.
The novel clamp for processing thin-walled cylinder part that the present invention mentions is for the difficult point of elongated thin cylinder part machinability difference, by improving installation way, adopt polyurethane rubber as tensioner element, solve the distortion produced in conventional processes, and then effectively control positional precision and the dimensional accuracy of part, effectively ensure that the crudy of part.As shown in Figure 1, spacer in this novel clamp 5 and tensioner element 4 matched in clearance, and spacer 5 and tensioner element 4 are divided into many groups is arranged on tube connector 3; Wherein, first group of spacer 5 and location-plate 2 close contact, last group tensioner element 4 and pressing plate 6 close contact.Hold down gag has been installed in pressing plate 6 side wherein, and this hold down gag is compressed by adjusting lock nut's 7 pairs of pressing plates 6.Tensioner element 4 in this novel clamp have employed polyurethane rubber, this polyurethane rubber to the tensioner excellent performance of part, its hot strength and percentage elongation high, thus load support power is large, damping property is fine, has excellent anti-wear performance and oil resistance simultaneously.
The novel clamp for processing thin-walled cylinder part that the present invention proposes is installed easy to operate, after part by one-step clamping, can complete processing, is conducive to the machining accuracy ensureing part, improves working (machining) efficiency.In actual use, by tightening the locking nut 7 in the hold down gag of pressing plate 6 side, clamping force is applied to pressing plate 6, active force is applied to polyurethane rubber by pressing plate 6 again, polyurethane rubber is under the compression of pressing plate 6, there is elastic deformation, produce radial forces, and then tensioner, support part.When expanding force between polyurethane rubber and part is enough large, the frictional force produced just can overcome the processing that cutting force completes part.After part machines, unclamp and tighten nut 7, now compression stress disappears, and the active force between polyurethane rubber and part disappears thereupon, just part can be taken out.Owing to adopting polyurethane rubber as tensioner element, therefore there is not radial clearance in this novel clamp being used for processing thin-walled cylinder part, can self-centering reach required positioning precision; Polyurethane rubber good processability simultaneously, the gap in a free state and between part outer is little, and when clamping, the radial deformation of many group polyurethane rubbers is identical, therefore ensure that the axiality of part and fixture.In addition, what polyurethane rubber contacted with part is polyurethane rubber face, therefore can not produce scuffing phenomenon to machined surface.
Present invention is disclosed a kind of novel clamp for processing thin-walled cylinder part, this novel clamp manufacture is simple, easy to operate, its strong point is many, area is large, there is excellent tensioner performance, can prevent part from deforming in process and trembleing, effectively ensure that machining accuracy and the instructions for use of part.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
