Abstract
The utility model discloses a positioning and clamping device for bearing bushings, and relates to a milling lathe. Aiming to design a positioning and clamping device for bearing bushings with an oil cylinder piston rod free from being affected by radial forces, the utility model provides a technical proposal that a positioning and clamping device for bearing bushings, which comprises a positioning rod and an oil cylinder, wherein axial line of the oil cylinder piston rod that is provided on the crossbeam coincides with axial line of the positioning rod. The utility model can be used for positioning and clamping purposes for horizontal bear bushing surface broaching machines.
Description
Technical field:
The utility model relates to a kind of grinding machine, particularly a kind of bearing shell positioning and clamping mechanism of horizontal bearing shell surface broaching machine.
Background technology:
The bearing shell positioning and clamping mechanism of existing surface broaching machine is by hydraulic oil cylinder driving, but because the oil cylinder piston bar that is located on the lathe crossbeam becomes 90 degree directions with backstay, the cross force that produces with 90 degree inclined-planes of oil cylinder piston bar promotes backstay the bearing shell location is clamped, and causes wearing and tearing leakage of oil to cylinder wall and act on radial load on the oil cylinder piston bar inclined-plane.
Summary of the invention:
The purpose of this utility model is a kind of bearing shell positioning and clamping mechanism of design, and this oil and piston rod are not subjected to the radial load effect.The technical solution of the utility model is that a kind of bearing shell positioning and clamping mechanism comprises backstay and oil cylinder, it is characterized in that: the axis that is located at the oil cylinder piston bar on the crossbeam and the axis of backstay are to overlapping.The utility model because be located at oil cylinder piston bar on the column and backstay on same axis, thereby do not have radial load to act on the oil cylinder piston bar, therefore, the utility model has the advantage of oil cylinder long service life compared with the prior art.
Description of drawings:
Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the utility model is elaborated, in order to eliminate the radial load of oil cylinder piston bar, oil cylinder piston bar 2 directions that need to be located on the crossbeam 1 become and the setting of backstay axis equidirectional by spending for 3 one-tenth 90 with backstay, and (referring to Fig. 2) gets final product head it off.
Claims (1)
1, a kind of bearing shell positioning and clamping mechanism comprises backstay and oil cylinder, it is characterized in that: the axis that is located at the oil cylinder piston bar on the crossbeam and the axis of backstay are to overlapping.
