It is further that a fixture block clamping device is provided with below the fixture block, the fixture block clamping device is by institute
State fixture block clamping.
It is further that the fixture block clamping device includes the bottom plate being fixed on CNC turntables, the two ends point of the bottom plate
It is not provided with a cylinder, the expansion link of the cylinder and is installed with a turnable briquetting.
It is further that two padded posts are provided with the bottom plate, one piece of connecting plate is installed with the padded post；Institute
State the locating dowel three for being provided with and being positioned for the fixture block on connecting plate.
It is further to be provided with lifting body in the padded post；The lifting body is made up of jigger pin and spring,
The spring is located in the padded post, and one end of the jigger pin is connected with the spring, the bottom of the other end and the fixture block
Portion is connected.
Compared with prior art, technological merit of the present utility model is：Using spring steel as cushion block pad at the bottom of instrument
Portion, goes uniformly to share the elastic deformation of workpiece, to ensure machining accuracy using the elasticity of spring steel.
Brief description of the drawings
, below will be to existing skill in order to illustrate more clearly of the technical scheme in the utility model prior art and embodiment
The accompanying drawing used required in art and embodiment description is briefly described.
Fig. 1 is the positive structure schematic of workpiece in the prior art；
Fig. 2 is the structure schematic diagram of workpiece in the prior art；
Fig. 3 is the structural representation of the resilient clamp fixture disclosed in embodiment one;
Fig. 4 is the structural representation of the resilient clamp fixture for getting rid of fixture block disclosed in embodiment one；
Fig. 5 is the structural representation of the backing plate disclosed in embodiment one；
Fig. 6 is the structural representation of the resilient clamp fixture disclosed in embodiment two.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
Embodiment one
Figure in the present embodiment is referring to Fig. 3-5.
Resilient clamp fixture, including fixture block 3, and it is installed in the backing plate 4 of fixture block bottom；It is provided with backing plate and several is inserted in folder
Lead 5 in block；The locating dowel 26 positioned for it with fixture block is additionally provided with backing plate.The top of fixture block, which has four, to be allowed
Position groove 7, the bottom land of slot to make way has the accommodating groove 8 of several equidistant arrangements；All set at top every slot to make way of correspondence of backing plate
It is equipped with a groove 16, every groove and is both provided with one block of spring steel 9；Spring steel is fixed on backing plate by bolt 17, and
Positioned by locating dowel 1 and backing plate；The top correspondence of spring steel, which is each housed at groove, is both provided with profiling cushion block 11.
During workpiece feeding, first workpiece is placed on spring steel and positioned, it is enterprising that fixture block then is placed on into backing plate again
Row positioning；Finally fixture block is pressed on backing plate, the clamping of workpiece is just completed this moment.
Because spring steel is the uniform leading role for sharing elastic deformation, therefore be locked on backing plate must be by pneumatic torque for spring steel
Spanner is carried out.
Embodiment two
Accompanying drawing in the present embodiment is referring to Fig. 6.
The processing of a general part, for the ease of clamping, typically can all select quick change all without a sleeve clamp is only used
Mode go set fixture clamping device.
A fixture block clamping device is provided with below fixture block.Fixture block clamping device includes the bottom being fixed on CNC turntables
Plate 12, the two ends of bottom plate, which are respectively arranged with a cylinder 13, the expansion link of cylinder, is installed with a turnable briquetting 14.
