Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary clamps, in particular to a special horizontal clamp for a crankcase. Background Art
[0002] Emulsion pumps are used in coal mining operations to supply emulsion to hydraulic supports. Their operating principle is that the rotation of the crankshaft drives the reciprocating motion of the piston, achieving fluid suction and discharge. Hydraulic supports support the roof, providing space for shearers to cut coal and preventing roof collapse. The emulsion is composed of 95% water and 5% oil. The hydraulic supports are supported and extended by hydraulic cylinders.
[0003] Among them, the crankcase structure of the emulsion pump is complex, and each outer surface needs to be processed after casting. Due to the special structure, the ordinary clamping mechanism can only process one of the surfaces after clamping, and re-clamping is required to process the next outer surface. The overall operation is cumbersome, the requirements for the operators are high, the work efficiency is low, the processing accuracy is low, and the yield is low. Utility Model Content

[0005] The technical solutions adopted in this utility model are as follows:
[0006] The top surfaces of the two left and right columns are respectively fixed with a pressure plate, and a stud is installed on the pressure plate, and the pressure plate presses the top surface of the crankcase body and is locked by the stud.
[0007] As a further improvement of the above technical solution:
[0008] The base plate is fixed to the machine tool workbench through fasteners.
[0009] A plurality of locking holes are formed on the bottom plate.
[0010] The left column is in a "C"-shaped structure.
[0011] The right column is in a right-angled structure.
[0012] The left limiting block is in a rectangular parallelepiped structure and has two through holes.
[0013] The middle limiting block is in a long strip structure.
[0014] The right limiting block is in an "L"-shaped structure.
[0015] The left column and the right column have the same height.
[0016] The left positioning block, the middle positioning block and the right positioning block are all in a convex-shaped structure.
[0017] The beneficial effects of the utility model are as follows:
[0018] The utility model has a compact and reasonable structure and is easy to operate. Through the mutual cooperation between the pressure plate, the positioning block, the limit plate, the bottom plate and the column and other components, the clamping work of the crankcase body can be conveniently completed, that is, the processing work of the four outer surfaces of the crankcase body can be completed by one clamping, which brings great convenience to the processing of the crankcase body, and has high processing precision, convenient operation and high work efficiency.
