Abstract
The invention belongs to the technical field of components of machine tools and discloses a clamp drive device of a motorcycle brake machine tool. The clamp drive device of the motorcycle brake machine tool comprises a single-action air cylinder, a pressure cylinder and a clamp drive cylinder, wherein the pressure cylinder is connected to the output face of an air cylinder body, the diameter of a pressure cylinder body is smaller than that of the air cylinder body, the output face of a pneumatic piston is connected with a piston of the pressure cylinder in the axial direction, the piston of the pressure cylinder extends into the pressure cylinder and isolates an air cavity of the air cylinder from an oil cavity of the pressure cylinder, the output end of the pressure cylinder is connected with an oil pressure hose, and the oil pressure hose is connected with an oil cavity of the clamp drive cylinder. The clamp drive device of the motorcycle brake machine tool is high in output pressure and low in cost.
Description
Technical field
The invention belongs to the component technology field of lathe.
Background technique
In traditional brake for motorcycle industry, in machining brake process, need break tensioner by artificial, and then progressively feed processing on universal lathe, its manufacturing efficiency of this processing mode is low, labor intensity is large, have certain skill set requirements, machining accuracy not high to operator and homogeneity of product cannot ensure.And break clamping can be ensured the precision of processing by the existing current corresponding fixture of employing air cylinder driven, but also there is shortcoming: existing cylinder adopts pressurized air as power source, delivery pressure is less, the clamping of fixture is not firm, and in order to improve the delivery pressure of cylinder, need cylinder cylinder head size to do greatly, cost increase is cut and can be increased the volume of whole lathe.
Summary of the invention
The invention is intended to provide a kind of delivery pressure larger and the fixture drive unit of lower-cost brake for motorcycle working machine tool.
Object of the present invention can be reached by following measures: the fixture drive unit of brake for motorcycle working machine tool, comprise single cylinder, also comprise pressurizing cylinder and fixture driving oil cylinder, described pressurizing cylinder connects and cylinder block output face, the diameter of cylinder of this pressurizing cylinder is less than the diameter of cylinder of cylinder, pneumatic piston output face and supercharging oil pressure piston shaft are to being connected, and this supercharging hydraulic piston stretches into pressurizing cylinder and the air cavity of cylinder and pressurised oil pumping cavity completely cut off; The output terminal of described pressurizing cylinder is connected with descaling hose, and this descaling hose and fixture drive the oil pocket of oil cylinder to be connected.
Technique scheme difference with the prior art is: export at pneumatic piston and have additional pressurizing cylinder piston, air cavity and oil pocket completely cut off after inserting pressurizing cylinder by pressurizing cylinder piston, and be less than cylinder block diameter due to the diameter of cylinder of pressurizing cylinder, corresponding, the diameter of pneumatic piston is then greater than pressurizing cylinder piston, the very little pressure of pneumatic piston one is applied to when cylinder passes into pressurized gas, pneumatic piston is again by this pressure effect and its little pressurizing cylinder piston of area ratio, pressurizing cylinder piston can be subject to high pressure thus squeezed fluid force feed along descaling hose, fixture drives the flowing of oil cylinder direction, high pressure is passed to fixture and drives oil cylinder.The present invention utilizes the piston of two different area sizes, and lower pressure is increased to tens times.Without the need to doing the cylinder size of large cylinder, while reducing cost, increase delivery pressure.
Further, described fixture driving oil cylinder comprises cylinder body, driven plunger with oil pocket, the output face of driven plunger is connected with fixture main shaft, between driven plunger and fixture main shaft, backspring is installed, descaling hose communicates with the oil pocket of cylinder body, hydraulic oil enters from descaling hose the oil pocket that fixture drives oil cylinder, thus promotion driven plunger moves, driven plunger drives fixture main axle moving, thus drive clamp brake for motorcycle, and during cylinder motion by reaction, hydraulic oil refluxes, driven plunger is returning position under the promotion of backspring.
Further, the piston area radius ratio of described pneumatic piston and charged piston is 4:1, utilizes piston area ratio larger between them, increases substantially delivery pressure.
Further, the side face of described hydraulic piston is provided with rubber seal ring, prevents hydraulic oil from leaking to cylinder.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the fixture drive unit embodiment of brake for motorcycle working machine tool of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
