Abstract
The utility model provides a clamping device for a crankshaft grinding machine workpiece. The clamping device has the advantages that the positioning center line movement of the workpiece can be prevented, and the workpeice indexing precision cannot be damaged. The clamping device comprises a workpiece press plate, wherein a cavity is arranged in the workpiece press plate, and a positioning block is fixedly arranged on the inner side of the workpiece press plate. The clamping device is characterized in that a press block is movably arranged in a position of the inner side of the workpiece press plate corresponding to the positioning block, and a spherical screw passes through the workpiece press plate to be connected with the press block through a connecting plate.
Description
Technical field
The utility model relates to the technical field of grinding machine components, is specially a kind of clamping device of crankshaft grinding machine workpiece.
Background technology
See Fig. 1, the clamping device of existing crankshaft grinding machine workpiece, it comprises top board 1, lower platen 2; Top board 1 forms a cavity with lower platen 2, and top board 1, lower platen 2 lean on bolt, nut to connect, and are fixed with briquetting 3 in the top board 1; Be fixed with locating piece 4 in the lower platen 2; Behind workpiece 6 calibration, will distinguish fastening nut 5, thereby make top board 1 drive briquetting 3 workpiece 6 is compressed.But in the process of tightening four nuts since differing in size and being not to tighten simultaneously of screwing force be easy to cause moving of workpiece centre of location line, thereby directly influence the workpiece indexing accuracy.
Summary of the invention
To the problems referred to above, the utility model provides a kind of clamping device of crankshaft grinding machine workpiece, can prevent moving of workpiece centre of location line, can not destroy the workpiece indexing accuracy.
Its technical scheme is such: a kind of clamping device of crankshaft grinding machine workpiece; It comprises the workpiece pressing plate; In the said workpiece pressing plate cavity is arranged; Said workpiece pressing plate inboard is fixed with locating piece, it is characterized in that: said workpiece pressing plate is movably set with briquetting on the inboard position corresponding with said locating piece, and sphere screw passes said workpiece pressing plate and connects said briquetting through connecting plate.
[0005]It is further characterized in that: said workpiece pressing plate comprises top board and lower platen; Said top board and said lower platen are fixedly connected to form a cavity through set bolt; Said lower platen inboard is fixed with locating piece, and said top board is movably set with briquetting on the inboard position corresponding with said locating piece; Said pressing plate cavity is a circular cavity; Said set bolt is four.
In the said structure of the utility model, adopt sphere screw to connect briquetting,, also just can not destroy indexing accuracy because the universal property of sphere screw is regulated the sphere screw briquetting and when workpiece pressing, can not produced eccentric force.
Description of drawings
Fig. 1 is the structural representation of the clamping device of existing crankshaft grinding machine workpiece;
Fig. 2 is the structural representation of the clamping device of the utility model crankshaft grinding machine workpiece.
The specific embodiment
See Fig. 2; The clamping device of a kind of crankshaft grinding machine workpiece of the utility model; It comprises top board 1 and lower platen 2, and top board 1 is connected through four set bolts 6 with lower platen 2 and forms a circular pressing plate cavity 8, and lower platen 2 inboards are fixed with locating piece 4; Top board 1 is movably set with briquetting 3 on the inboard position corresponding with locating piece 4, and sphere screw 5 passes top board 1 and passes through connecting plate 7 connection briquettings 3.
Behind workpiece 9 calibration, turn sphere screw 5, make briquetting 3 with Work-sheet pressing, because sphere screw has universal property,, just can not destroy the indexing accuracy of workpiece so briquetting can not produce eccentric force when workpiece pressing yet.
