Background
At present, the automobile engine manufacturing industry knows that when a flywheel shell is machined, a clamp needs to be adopted to position the flywheel shell. The conventional clamp is mainly composed of a base plate, a pressing plate and bolts for connecting the base plate and the pressing plate together. The bottom plate and the top plate are respectively provided with a through hole and a screw hole which correspond to each other, the bottom plate is fixed on the workbench during working, the machined flywheel housing is arranged between the bottom plate and the pressing plate, and finally the machined flywheel housing is clamped between the bottom plate and the pressing plate by means of a fastener consisting of the through hole, the screw hole, a bolt and a nut, so that the machined flywheel housing is clamped and positioned. Although the clamping and positioning of the flywheel housing can be realized by adopting the clamp, the whole process needs manual operation, so that the production efficiency is low, the repeated positioning precision is low, and the product quality is difficult to ensure.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the utility model is to provide an anchor clamps for processing bell housing faying face. By adopting the clamp, the production efficiency can be improved, and the product quality can be ensured.
The utility model discloses the above-mentioned problem that solves is realized by following technical scheme:
the utility model discloses an anchor clamps for processing bell housing faying face contain the bottom plate, and its characteristics are: the center of the bottom plate is provided with a tensioning seat, and tensioning oil cylinders for propping against the inner wall of the flywheel housing (opening part) are uniformly distributed on the periphery of the outer wall of the tensioning seat. Lever oil cylinders for pressing the edge of the opening part of the flywheel housing are uniformly distributed on the bottom plate around the tensioning seat, and upper jacking oil cylinders for jacking the edge of the bottom surface of the flywheel housing are arranged on the bottom plate between the adjacent lever oil cylinders.
The tensioning seat is approximately cylindrical and is higher than the lever oil cylinder, three vertical tangent planes are uniformly distributed on the periphery of the outer side surface of the tensioning seat, blind holes are formed in the vertical tangent planes, the tensioning oil cylinders are located in the corresponding blind holes, and the outer ends of piston rods of the tensioning seat face outwards.
The utility model discloses a further improvement is that, the upper end of the seat that rises even has the fork form board, all has first locating head on two forks of fork form board. The axes of the two positioning heads are parallel, and the outer ends of the two positioning heads face outwards. One side of the fork-shaped plate opposite to the fork head is connected with a push head, and the axial direction of the push head is parallel to the axial direction of the first positioning head.
The utility model discloses a further improvement scheme is, there are first cushion and second cushion between lever cylinder and last top hydro-cylinder and bottom plate respectively.
According to the above technical scheme, because the utility model discloses a bottom plate center has the seat that rises to rise, and the equipartition all around of the seat outer wall that rises has the hydro-cylinder that rises that is used for withstanding bell housing (oral area) inner wall that rises. Lever oil cylinders for pressing the edge of the opening part of the flywheel housing are uniformly distributed on the bottom plate around the tensioning seat, and upper jacking oil cylinders for jacking the edge of the bottom surface of the flywheel housing are arranged on the bottom plate between the adjacent lever oil cylinders. When the flywheel shell machining device works, a machined flywheel shell is placed on the tensioning seat, the tensioning oil cylinder is started to enable the piston rod of the tensioning oil cylinder to extend outwards, and the flywheel shell is pushed to be in contact with the first positioning head. And then, starting the lever oil cylinder to enable the pressing plate to move downwards, and pressing the flywheel shell between the pressing plate of the lever oil cylinder and the upper jacking oil cylinder. Therefore, the clamping and the positioning of the flywheel housing can be realized without manual operation. Compared with the prior art, the production efficiency is improved, the repeated positioning precision of the processed part is improved, and the product quality is greatly improved.
