Technical field
The present invention relates to the hydraulic press field, especially a kind of movable workbench of hydraulic press that is used for promotes and the composite construction that clamps.
Background technology
Present known hydraulic press has mostly been installed travelling table, is convenient to installation, location and the replacing of mould and workpiece, reduces the manually-operated difficulty, increases work efficiency.Existing movable workbench of hydraulic press generally adopts oil cylinder to realize promoting and clamping; Below the travelling table of hydraulic press, there are four lift cylinders and four to be used for the fixing clamping cylinder of travelling table; When travelling table moves; With four lift cylinders workbench is lifted earlier, move in and out action then; When travelling table uses as support unit; Through four clamping cylinders with travelling table and hydraulic press matrix firmly clamp realize fixing; Its shortcoming is: it is big to take up room, and the travelling table below will be reserved eight positions and be used to put lift cylinder and clamping cylinder; Eight have 12 oil inlet and outlets, eight hydraulic fluid ports wherein are linked to be a road binders, and four hydraulic fluid ports in addition are linked to be another road binders, make the connection of whole pipe-line system and layout become very complicated, make troubles to operation of equipment and maintenance; Two mechanism's independent operatings of clamping on the travelling table and lifting, equipment then will be for it provides more power, and energy utilization rate is low, and cost is high.
Summary of the invention
Problem to be solved by this invention just provides a kind of movable workbench of hydraulic press simple in structure and promotes and clamping composite structure, simplifies the pipe-line system of hydraulic press, reduces taking up room of equipment, reduces cost, and is more convenient to operate.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: a kind of lifting of movable workbench of hydraulic press and clamping composite structure; Comprise the hydraulic press body, be located at the oil cylinder that hydraulic press body top is with the travelling table of roller, is located at hydraulic press body below; It is characterized in that: also comprise the positioning sleeve that is located on the hydraulic press body and can be in positioning sleeve axially movable slide block; Said slider bottom connects the piston end of oil cylinder, and said upper end of slide block is provided with supporting structure, and said supporting structure is lifted the lifting that roller is realized travelling table when oil cylinder promotion slide block is up; Also be provided with clamping structure between said upper end of slide block and the travelling table, when oil cylinder pulling slide block down, travelling table be clamped on the hydraulic press body through clamping structure.
Further; Said clamping structure comprises two clamp arms that are located on the upper end of slide block face and is located on the travelling table and said clamp arm corresponding groove; The top of said clamp arm is stretched in the space between roller and the travelling table and is formed one to the extension of travelling table one side and clamps protruding eaves, and the protruding eaves compressed grooves of described clamping bottom surface is fixedly clamped travelling table on the hydraulic press body.
Further, said supporting structure is the supporting concave station that is made up of described two clamp arms and upper end of slide block face, lifts the lifting that roller is realized travelling table through the supporting concave station when slide block is up.
Further, be lined with a guide rail plate bottom the said supporting concave station and be used for support roller.Increase and decrease guide rail plate height can be adjusted the hoisting depth of travelling table.
Further, also be provided with the position limiting structure of anti-limited slip block deflection between said positioning sleeve inwall and the slide block.
Further, described position limiting structure comprises the feather key that is fixed on slider side wall and axially is opened in the guiding keyway that the positioning sleeve inwall supplies said feather key to slide.Feather key cooperates with the guiding keyway can make slide block in positioning sleeve, easily slide, and can prevent that again limited slip block deflects in slip.
Beneficial effect of the present invention: the present invention has utilized a slide block by hydraulic oil cylinder driving to realize lifting and the clamping of travelling table; The supporting concave station that promotes usefulness on the slide block is compound as a whole with the clamp arm that clamps usefulness; The frame for movement and the pipe-line system of hydraulic press have been simplified; Significantly reduced and taken up room, made travelling table under the smaller situation of appearance and size, also can use this structure to be used for promoting and clamping; Because promoting compound with anchor clamps is one, has saved the part power consumption, reduces cost.
