Furthermore, the pressing device comprises a pushing sleeve, a compression spring and a pressing and supporting plate; the pushing sleeve, the compression spring and the pressing support plate are sequentially sleeved on the positioning rod towards the inner direction of the fixture box body along the outside.
Furthermore, the side of the pushing and pressing sleeve away from the inside of the fixture box body is provided with a positioning lug, the positioning lug is provided with a pin hole, and the positioning rod is fixed on the fixture box body through a pin.
Furthermore, the pressing and supporting plate is a square plate with a hole in the middle, and the positioning rod penetrates through the pressing and supporting plate through the hole.
Furthermore, an anti-skid soft cushion is arranged on one side of the pressing and supporting plate facing the oil cylinder base workpiece.
Preferably, the surface of the anti-skid soft cushion is of a twill structure.
Compared with the prior art, the beneficial effects of the utility model are that: the positioning rod penetrating through the middle part of the clamp box body can penetrate through the two working arms of the oil cylinder base to enable a workpiece to be fixed in the vertical direction, and the two working arms of the workpiece can be pressed in the horizontal direction by the pressing devices such as the pushing sleeve, the compression spring and the pressing and supporting plate which are symmetrically sleeved on the positioning rod in sequence, so that the position of the workpiece is fixed and the workpiece is kept at the central position. The machining of the outer side base of the oil cylinder blank and the high concentricity of the two working arms are guaranteed, and the quality requirement of subsequent equipment assembly is met.
