Summary of the invention
When the purpose of this invention is to provide a kind of oil cylinder near end of travel available buffer, good stability be used for fuel cylinder driving mechanism on the anchor clamps with pooling feature, overcome the deficiencies in the prior art.
The fuel cylinder driving mechanism that is used on the anchor clamps of the present invention with pooling feature, comprise clamp body, on clamp body, be provided with oil cylinder, one end of oil cylinder has left end cap, the other end has right end cap, one end of the rack piston that matches with oil cylinder has left chamber and is communicated with left oil port on the left end cap, and the other end of rack piston has right chamber and is communicated with right oil port on the right end cap;
There is the left end cap inner chamber inboard of left end cap, is connected to plunger at the left end of rack piston, and plunger and left end cap inner chamber match;
Chamber, a left side is connected with left oil port by the left end cap inner chamber; Between left oil port and left chamber, be provided with check valve on the left end cap;
On left end cap, be processed with spool bore, this spool bore internal thread is connected with spool, is processed with intercommunicating pore on the left end cap, and intercommunicating pore is communicated with left chamber, spool bore and left end cap inner chamber, be connected with fastening bolt at the spool bore internal thread, the port of spool bore has the plug of band sealing ring.
The fuel cylinder driving mechanism that is used on the anchor clamps of the present invention with pooling feature, when rack piston during near left end, plunger enters the left end cap inner chamber, cut off being communicated with of left chamber and left oil port herein, the hydraulic oil in left chamber is released no longer from here, because intercommunicating pore is passed through in left chamber, spool bore, the left end cap inner chamber is communicated with left oil port, hydraulic oil in the left chamber is released through above-mentioned continuous hole, spool transfers to correct position and is located by fastening bolt in this process, hydraulic fluid flow rate between control intercommunicating pore and the left end cap inner chamber, play the effect of throttling herein, obtain buffering when finally making rack piston near left end, overcome the phenomenon of end impact, had stability preferably.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention;
Fig. 2 is an A-A sectional schematic diagram shown in Figure 1.
The specific embodiment
As shown in Figure 1, 2: 4 is the clamp body, on clamp body 4, be fixed with oil cylinder 2, the right-hand member of oil cylinder 2 has right end cap 1, right end cap 1 is fixedlyed connected with clamp body 4 by bolt, be threaded the right bolt 14 of adjusting also with fastening nut 15 fastening location in the center of right end cap 1, the position that is used to set up the right stop of piston.Being processed with right oil port 16 on right end cap 1 is used for linking to each other with hydraulic control.The right-hand member of the rack piston 3 that matches with oil cylinder 2 forms right chamber 13.Right chamber 13 is communicated with right oil port 16.
The opening of rack piston 3 middle parts from oil cylinder 2 tops exposes and is meshed with gear 12, and the rotating shaft of gear 12 connects the rotation that anchor clamps turntable face is used to drive the turntable face.
Left end at oil cylinder 2 has left end cap 5, and left end cap 5 is fixedlyed connected with clamp body 4 by bolt.Bolt 11 is adjusted on the left side that has been threaded on left end cap 5, the fastening location of back of the body cap that has been threaded, the outer end that bolt 11 is adjusted on a left side, and the left dead-centre position that bolt 11 can be adjusted piston is adjusted on a left side.
Be processed with the left end cap inner chamber 10 of circular hole in the center of left end cap 5, left end cap inner chamber 10 is communicated with the left chamber 8 that rack piston 3 left ends form.
Left end at rack piston 3 is connected with plunger 9, and plunger 9 matches with left end cap inner chamber 10.
Being processed with left oil port 7 on left end cap 5 is communicated with left end cap inner chamber 10.
