Abstract
The invention relates to a movable workbench clamping method for a hydraulic press. The method comprises the steps as follows: a movable workbench is driven by a motor to move on a track, and a movable workbench in-position proximity switch is adopted to detect whether the movable workbench moves in position; and when the movable workbench moves in position, the movable workbench stops moving, a clamping cylinder drives a top plate to begin descending, meanwhile, a pressure detection switch starts to detect pressure at an oil inlet of the clamping cylinder, when the pressure increases gradually, the clamping cylinder stops driving, and the movable workbench is clamped at the moment. A clamping device for realizing the clamping method mainly comprises the movable workbench, a fixed workbench, the detection switch, the clamping cylinder and the top plate. The invention further relates to a special clamping device for realizing the clamping method. The movable workbench clamping method and the special clamping device thereof for the hydraulic press has the advantages that lower spacing is cancelled, the proximity switch arranged inside the fixed workbench is used for detection, and whether the movable workbench is clamped is determined by the pressure of the clamping cylinder.

At present, in the hydraulic press using on existing market, the mode that the clamp mechanism of its movable table adopts is: four groups of sense switches are installed in stationary work-table, every group of sense switch detects by upper limit and lower limit detection two parts composition, therefore the cost compare needing is high, and when whether detected activity workbench clamps, need to detect to judge whether movable table clamps by four lower limit sense switches, trouble relatively simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hydraulic press movable table clamping means and Special clamping device thereof.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of hydraulic press movable table clamping means, and its innovative point is: described step is:
A) roller of movable table bottom is driven on the track being positioned on stationary work-table and is moved by drive motors, whether movable table is walked to put in place detects simultaneously by being positioned at the movable table of the stationary work-table approach switch that puts in place;
B), if testing result is no in step a, by drive motors motor, drive the roller of movable table bottom to walk on;
C) if testing result is yes in step a, by motor, drive the roller of movable table bottom to stop walking, then, by clamping cylinder, drive top board to start descending, be positioned at movable table on top board simultaneously and also start descendingly, pressure detection switch starts the pressure of the oil-in of clamping cylinder to detect simultaneously;
D) in step c, when the pressure detecting when pressure detection switch increases gradually, clamping cylinder stops driving, and the top board that is now positioned at the upper end of taking blame for others clamps movable table.
A kind of Special clamping device of realizing above-mentioned clamping means, its innovative point is: mainly comprise movable table, stationary work-table, sense switch, clamping cylinder and top board, described sense switch comprises the movable table approach switch that puts in place, pressure detection switch and the stationary work-table clamping cylinder upper limit approach switch that puts in place, bottom position at movable table is provided with roller, on the upper surface of stationary work-table, be provided with the track matching with roller simultaneously, the movable table that movable table the is detected approach switch that puts in place is installed in stationary work-table, oil-in at clamping cylinder goes out to be provided with the pressure detection switch that the pressure of clamping cylinder oil-in is detected, described clamping cylinder is positioned at the inside of stationary work-table, upper end at clamping cylinder is provided with top board, the roller of described top board and movable table matches, and can be driven by clamping cylinder, lower movement.
The invention has the advantages that: cancel original clamping cylinder lower limit approach switch that puts in place, by the approach switch that puts in place of the movable table in stationary work-table, detect, and the pressure of the clamping cylinder being detected by clamping cylinder pressure detection switch, cooperation between the two judges whether movable table clamps, very convenient, provide cost savings simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hydraulic press movable table clamping device of the present invention.
The specific embodiment
Schematic diagram is as shown in Figure 1 known, and hydraulic press movable table clamping device of the present invention mainly comprises movable table 3, stationary work-table 2, sense switch, clamping cylinder and top board 1.
In the bottom of movable table 3, roller 7 is installed, at the medium position of the circumferential surface of roller 7, is provided with the guiding rib that a circle prevents that roller 7 from wandering off, the cross section at the two ends of the bottom of movable table 3 is the L shape being oppositely arranged.
Inside at stationary work-table 2 is provided with clamping cylinder, clamping cylinder mainly comprises clamping cylinder body 8 and piston rod 4, medium position at piston rod 4 is provided with a rectangular preiection 5, rectangular preiection 5 is clamping between cylinder body 8 and stationary work-table 2, top at the piston rod 4 of clamping cylinder is provided with top board 3, the T-shaped shape of cross section of top board 3, and top board 3 matches with the two ends of the bottom of movable table 3, is provided with the cavity matching with roller 7 at the middle part of top board 3.
Sense switch comprises movable table approach switch, pressure detection switch and the clamping cylinder upper limit approach switch that puts in place that puts in place.The movable table approach switch that puts in place is arranged on the inside of stationary work-table 2, for detection of judging whether movable table 3 walks, put in place, pressure detection switch is arranged on the oil-in place of clamping cylinder, pressure for detection of clamping cylinder oil-in, the clamping cylinder upper limit approach switch that puts in place is arranged on stationary work-table 2 and clamps between cylinder body 8, for the rectangular preiection 5 on piston rod 4, detects.
The step of utilizing above-mentioned clamping device to clamp movable table is specific as follows:
