Abstract
The utility model discloses a hydraulic flexible clamping device which comprises a compression cylinder. A cylinder push rod is arranged on the upper side of the compression cylinder, the top of the cylinder push rod is inserted into a rigid pressure plate, the right end of the rigid pressure plate is a flexible compression end, a silicon rubber cushion is adhered on the lower surface of the flexible compression end, and a floating support cylinder is arranged below the silicon rubber cushion. The hydraulic flexible clamping device has the advantages that the hydraulic flexible clamping device is of a hydraulic flexible clamping structure, accordingly, the problem of machining deformation of thin-walled parts with poor rigidity due to the fact that clamping force cannot be adjusted can be solved, and the dimensional precision of parts can be guaranteed; owing to the pressure plate with the cushion, a vibration absorption effect can be realized, and the problem of surface vibration grains of machined surfaces due to machining vibration can be solved; support force can be easily matched with compression force during clamping, accordingly, a hydraulic control system can be simplified, and the cost can be lowered.
Description
technical field:
The utility model relates to part processing clamp technical field, relates in particular to a kind of flexible hydraulic clamping device.
background technology:
For shape matching complexity and self the rigidity processing of poor automobile thin-walled parts again, generally on clamp for machining, except configuration hydraulic pressure fixed support and compressing unit, also can at the weaker position of some rigidity of part to be processed, increase some supports and compressing unit as required, to strengthen part to be processed, add the rigidity in man-hour, guaranteeing dimensional accuracy and the surface quality of part to be processed after processing.Existing common hydraulically operated fixture, general by the upper surface at part and lower surface applies thrust respectively and support force is realized clamping, but be rigidity owing to applying the pressing plate of thrust, therefore the accurately pressure of controlled pressure oil cylinder, makes support force and thrust be difficult to coupling, causes part deformation and surface quality bad, in addition, if increase pressure control unit in oil circuit, regulate, not only the space of fixture does not allow, and cost also can improve.
utility model content:
The purpose of this utility model is exactly in order to solve existing issue, and provide a kind of flexible hydraulic clamping device, solve the poor thin-walled parts of rigidity and cannot adjust because of clamping force the problem that causes machining deformation, guaranteed the dimensional accuracy of part, in addition, pressing plate by use with cushion, not only there is absorbing effect, improved the machined surface surface chatter mark that processing vibration causes, and support force and thrust when clamping are easily mated, simplified hydraulic control system, reduced costs.
Technology solution of the present utility model is as follows:
Flexible hydraulic clamping device, include compressed oil cylinder, the top of compressed oil cylinder is cylinder putter, cylinder putter top is inserted with Rigid Plates Under Compression, described Rigid Plates Under Compression right-hand member is the flexible end that compresses, the flexible end lower surface that compresses is stained with one deck silicon rubber cushion, and silicon rubber cushion below is provided with float support oil cylinder.
As preferably, described silicon rubber cushion thickness is 4 ~ 6mm.
As preferably, described Rigid Plates Under Compression left end has stepped hole, and the aperture, top of stepped hole is greater than aperture, below, in stepped hole, be inserted with cylinder putter, cylinder putter upper end has arc groove, and arc groove position, higher than the step surface of stepped hole, is placed with jump ring in arc groove.
As preferably, described float support oil cylinder top is support end, and support end surface is arcwall face.
The beneficial effects of the utility model are:
The utility model structure has adopted flexible hydraulic clamping structure, solve the poor thin-walled parts of rigidity and cannot adjust the problem that causes machining deformation because of clamping force, guaranteed the dimensional accuracy of part, in addition, the pressing plate by use with cushion, not only has absorbing effect, improved the machined surface surface chatter mark that processing vibration causes, and to clamp time support force and thrust easily mated, simplified hydraulic control system, reduce costs.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
In figure: 1, compressed oil cylinder; 2, cylinder putter; 3, Rigid Plates Under Compression; 4, silicon rubber cushion; 5, float support oil cylinder; 6, jump ring; 7, part; 21, arc groove; 31, the flexible end that compresses; 32, stepped hole; 51, support end.
the specific embodiment:
As shown in Figure 1, flexible hydraulic clamping device, include compressed oil cylinder 1, the top of compressed oil cylinder 1 is cylinder putter 2, cylinder putter 2 tops are inserted with Rigid Plates Under Compression 3, described Rigid Plates Under Compression 3 right-hand members are the flexible end 31 that compresses, and flexible end 31 lower surfaces that compress are stained with one deck silicon rubber cushion 4, and silicon rubber cushion 4 belows are provided with float support oil cylinder 5.
Particularly, described silicon rubber cushion 4 thickness are 4 ~ 6mm.
Particularly, described Rigid Plates Under Compression 3 left ends have stepped hole 32, the aperture, top of stepped hole 32 is greater than aperture, below, in stepped hole 32, be inserted with cylinder putter 2, cylinder putter 2 upper ends have arc groove 21, arc groove 21 positions, higher than the step surface of stepped hole 32, are placed with jump ring 6 in arc groove 21.
Particularly, described float support oil cylinder 5 tops are support end 51, and support end 51 surfaces are arcwall face.
Operation principle of the present utility model is: part 7 compresses between end 31 and the support end 51 of float support oil cylinder 5 in flexibility, the cylinder putter 2 of compressed oil cylinder 1 drives Rigid Plates Under Compression 3 to produce thrust downwards, make flexible silicon rubber cushion 4 compressing components 7 that compress end 31, the float support oil cylinder 5 of part 7 belows produces support force upwards, in compaction process, because silicon rubber material is soft, deflection is large, can change with stressed size with the contact area of part 7, therefore can reach the ratio of meticulous coupling support force and clamping force.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
