Description

Technical Field

[0001] The utility model relates to the technical field of engine cylinder body processing, in particular to an engine cylinder body clamp. Background Art

[0002] The engine block is a structure that contains the cylinders and other components of the internal combustion engine. In early automobile engines, the engine block consisted of only the cylinder block and a separate crankcase. Modern engine blocks usually integrate the crankcase and cylinder block into a single component. During the production and processing of the cylinder block, such as drilling and grinding, it is necessary to limit its position. The commonly used structure now is the engine block fixture;

[0003] In the actual processing of the existing engine fixture, the clamping position cannot be processed, and the comprehensiveness of the processing needs to be improved. In addition, the surface of the existing fixture table adopts a threaded structure, which leads to many groove structures on the surface of the processing table. In this way, during the subsequent processing process, debris is easily accumulated in the groove, which makes subsequent cleaning more troublesome. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an engine cylinder block clamp. Compared with the prior art, the clamp has a positioning function, which facilitates the limiting work. In addition, the alternating use of two groups of clamping components can ensure the comprehensiveness of the processing.

[0007] Preferably, a rubber pad is provided on a side of each second movable plate away from the corresponding second piston rod.

[0008] Preferably, a plurality of support frames are installed at the lower end of the operating table.

[0009] Preferably, the driving mechanism includes a first fixed plate and a mounting plate which are symmetrically fixedly connected to the left and right side walls of the operating table, and the upper end of each of the first fixed plates is symmetrically fixedly connected to two first piston cylinders, and each of the first piston cylinders is provided with a first piston block which can slide up and down, and the upper end of each of the first piston blocks is fixedly connected to a first piston rod, and the upper ends of every two corresponding first piston rods are commonly fixedly connected to a connecting plate.

[0010] Preferably, the lower end of each mounting plate is fixedly connected to a hydraulic telescopic rod, and the upper end of each hydraulic telescopic rod is fixedly connected to the upper end of the corresponding connecting plate.

[0011] Preferably, the bottom space of each first piston cylinder is connected to the corresponding second piston cylinder through a connecting pipe, and the bottom space of each first piston cylinder, the connecting pipe and the space on one side of the second piston cylinder away from the middle of the operating table are filled with hydraulic oil.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Left and right clamps and front and rear clamps are provided, and the two can cooperate with each other to position the engine cylinder block to be processed in the middle, which is convenient for subsequent processing. In addition, the above-mentioned two clamping structures can be used alternately, which can avoid the generation of processing dead angles.
