Description

Lifting and clamping device

Technical field

The utility model relates to clamping and fixing device, and is particularly a kind of by the be fixedly clamped clamping and fixing device of travelling table roller of hydraulic piston.

Background technology

In the prior art, the movable workbench that often will place processing work in the machining is to ad-hoc location and fixing, so that next step operation, in this process, need workbench fixing quickly and easily very necessary, otherwise can influence working (machining) efficiency, the traditional type clamping device is often independently finished the clamping operation respectively with lifting cylinder and clamping cylinder, and cost is higher like this, the oil circuit complexity.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of lifting and clamping device, lifting and clamping is made by same cylinder realize that the travelling table that can be fixedly clamped fast also can be removed the workbench clamped position rapidly, has improved operating efficiency.

The technical solution of the utility model is such realization: a kind of lifting and clamping device, form by clamping cylinder and lifting clamping seats, wherein:

1) this clamping cylinder is made up of cylinder body, piston and cylinder cap, this cylinder body is fixed in seat stand face down, form lifting oil pressure chamber between this piston and this cylinder body inner bottom part, and be communicated with bottom oil-in on this cylinder body, form between ring week and the cylinder cap in this piston ring week, cylinder body and clamp the oil pressure chamber, and be communicated with top oil-in on this cylinder body;

2) push rod of this piston is fixed in this lifting clamping seats, and this lifting clamping seats upwards forms is convenient to the U type groove that the workbench upper roller slips into, and these U type groove both sides form two button hooks, and with the workbench of roller both sides on the corresponding fastening of two Button Blocks.

As further improvement of the utility model, the push rod of this piston is through at this U type trench bottom, and by the track pad that is fixed in this push rod end this push rod end is defined in this lifting clamping seats.

As further improvement of the utility model, this cylinder cap is by first seal and this piston seal sliding-contact, and this cylinder cap is sealingly fastened in this cylinder body by second seal simultaneously.

Useful technique effect of the present utility model is: this cylinder body is fixed in seat stand face down, and be provided with two oil pressure chambers between this piston and this cylinder body, wherein lifting oil pressure chamber is between this piston base and cylinder body inner bottom part, when being pressed into oil by the bottom oil-in that is communicated with it, the lifting clamping seats that just promotes this piston and connection together rises, thereby Button Block corresponding on button hook and the travelling table on this lifting clamping seats is unclamped, and travelling table discharges; Another clamping oil pressure chamber encircles between week and the cylinder cap in this piston ring week, cylinder body, when being pressed into oil by the top oil-in that is communicated with it, the lifting clamping seats that just promotes this piston and connection descends, just driving this lifting clamping seats descends, thereby make button hook on this lifting clamping seats fasten Button Block corresponding on this travelling table, reached travelling table is gripped.U type groove on this lifting clamping seats is convenient to roller on the travelling table and is slipped into fixingly, reduces the lifting and clamping device assembly like this, thereby reduces cost.

Description of drawings

Fig. 1 is in the structural representation of rising release conditions for lifting clamping seats described in the utility model;

Fig. 2 is in the structural representation of decline tightening state for lifting clamping seats described in the utility model.

The specific embodiment

In conjunction with Fig. 1 and Fig. 2, below be further described:

A kind of lifting and clamping device, form by clamping cylinder and lifting clamping seats 5, wherein this clamping cylinder is made up of cylinder body 1, piston 2 and cylinder cap 4, this cylinder body 1 is fixed in seat stand face 9 down, form lifting oil pressure chamber 10 between this piston 2 and this cylinder body 1 inner bottom part, and be communicated with bottom oil-in 11 on this cylinder body 1, form clamping oil pressure chamber 12 between ring week and the cylinder cap 4 in these 2 ring weeks of piston, the cylinder body 1, and be communicated with top oil-in 13 on this cylinder body 1; This lifting clamping seats 5 upwards forms is convenient to the U type groove 52 that workbench upper roller 7 slips into, the push rod 21 of this piston is through at this U type groove 52 bottoms, and this push rod end is defined in this lifting clamping seats 5 by the track pad 6 that is fixed in this push rod end, these U type groove 52 both sides form two button hooks 511,512, and with the workbench of roller both sides on 811, the 812 corresponding fastenings of two Button Blocks.

The push rod 21 of this piston is through at this U type groove 52 bottoms, and by the track pad 6 that is fixed in these push rod 21 ends these push rod 21 ends is defined in this lifting clamping seats 5.

This cylinder cap 4 is by first seal 31 and these piston 2 sealing sliding-contacts, and this cylinder cap 4 is sealingly fastened in this cylinder body 1 by second seal 32 simultaneously.

Operation principle of the present utility model is:

Original state: travelling table 8 is moved on the track pad 6 of U type groove 52 bottoms by workbench upper roller 7, and by positioner, travelling table 8 upper rollers 7 are positioned at the center of lifting clamping seats 5;

Workbench clamps: when top oil-in 11 oilings on cylinder body 1, promoting piston 2 moves downward, piston 2 drives whole lifting clamping seats 5 and track pad 6 moves downward, workbench 8 is sunk to down on the seat stand face 9, piston 2 drives lifting clamping seats 5 and track pad 6 continues to move downward, make workbench 8 clamped, roller 7 can't move;

The workbench lifting: when bottom oil-in 13 oilings on cylinder body 1, promote piston 2 and move upward, piston 2 drives whole lifting clamping seats 5 and track pad 6 moves upward, and track pad 6 is asking 7 liftings of workbench upper roller to get back to initial position.

The utility model is simple in structure, easy to install and use, suitable chassis lifting can be provided for the mobile trolley used formula hydraulic press of various different sizes and clamp function, also can effectively reduce the cost of lifting and clamping device, can be used for the lifting and the clamping of travelling table on similar other forging equipments of large-scale blanking equipment (comprising hydraulic press equipment and crank-type punching machine) and operating mode.
