Description

Four post adjustable manual presses

Technical field

The utility model relates to the device of mechanical installation or removal, the adjustable hand press of promptly a kind of four posts.

Background technology

In mechanical installation or removal; in regular meeting runs into the component of machine load hole; or situation about from the hole, extruding; owing to cooperate very tightly, pack into or extrudes relatively difficulty, a kind of vertical shape press of two posts arranged in the market; this press is driven the descent of piston of oil cylinder by oil pump; workpiece is exerted pressure, because the stroke range of piston is very narrow, the limited size system of the workpiece of pressing; if workpiece is big; put to enter,, then use a lot of piece cushion blocks if workpiece is little; instability during pressurization; two rod structures are also toppled over easily, and some special-purpose press can only be pressed some specific parts, can not be general.

Summary of the invention

In order to overcome two post vertical door shape press piston stroke narrow range, the unsettled shortcoming of two posts, the utility model proposes the new design of a kind of four posts, hand press that piston stroke is adjustable.

This four post adjustable manual presses, comprise support from the bottom to top, support, 4 root posts, adjustable shelf, top board, screw mandrel and handle, it is characterized in that, the support center is porose, be fixed on the support, 4 root posts are fixed on the support as 4 summits of rectangle, adjustable shelf is by upper plate, 4 isometric connecting rods are formed between lower plate and the upper and lower plates, porose on four angles of upper plate and lower plate, column passes from the hole, adjustable shelf can be slided on column, there is sliding sleeve at the upper plate center by bearing fixing, sliding sleeve also is fixed on the lower end of screw mandrel simultaneously, top board is fixed on the column upper end, the top board center fixation has nut, screw mandrel passes from nut, and matches with nut, in the hole of screw mandrel upper end handle is housed, oil cylinder is equipped with at the adjustable shelf middle part, the dead in line of oil cylinder and screw mandrel, oil cylinder upper end and sliding sleeve lower plane are adjacent to, and piston is equipped with in oil cylinder inside, spring is housed on the piston, the piston rod of piston bottom stretches out outside the oil cylinder, and piston-rod lower end is fixed with pressure head, and oil cylinder top links to each other with oil pump by oil pipe, oil pump is positioned at a side of oil cylinder, is fixed on the lower plate of adjustable shelf.

One end of oil pump is an oil pipe, the other end of oil pump is a high pressure piston and a low-pressure piston, these two pistons stretch out outside the oil pump, the piston upper end is connected by the rear portion of pin, hole and depression bar, the rear end of depression bar is connected by pin, hole and pole upper end, strut fixation also has switch valve on the oil pump on the shell of oil pump.

The course of work is as follows: the workpiece that needs are exerted pressure is placed on the base, shakes handle, rotary screw rod, allow pressure head near workpiece, shut the switch valve on the oil pump, hold the depression bar front end, the depression bar that fluctuates is gone into the oil pressure in the oil pump in the oil cylinder, promotes descent of piston, produce pressure, pressure head extrudes the part that needs in the workpiece to extrude, and opens the switch valve on the oil pump then, oil pressure in the oil cylinder reduces, under the effect of spring, piston rises, and oil is got back in the oil pump.

The utility model has the advantages that:

1, screw rod has increased the stroke range of piston, can process workpiece of all sizes;

2, four rectangular layouts of column, stabilization of equipment performance is good, and is simple for structure, few with material, and four columns can bear bigger pulling force;

3, highly versatile, not electricity consumption, flexible, also can make horizontal.
