Abstract
The utility model provides a tool change support retaining mechanism of rod flying shears. The retaining mechanism comprises a box body and a tool holder and is characterized by also comprising a tool rest connecting rod, piston, a threaded bushing, a locking wedge, a dish spring and a screw, wherein the tool holder is installed on the tool rest connecting rod, the locking wedge is also installed on the tool rest connecting rod, and the screw is fixedly connected with the tool rest connecting rod; the dish spring penetrates through a screw shank, one end of the dish spring is abutted against the screw, and the other end of the dish spring is abutted against the locking wedge; the threaded bushing is installed on the tool rest connecting rod, the piston penetrates through the threaded bushing and is installed on a piston hole on the tool rest connecting rod; and the tool rest connecting rod is provided with an oil hole which is connected with the piston hole. The retaining mechanism provided by the utility model has the beneficial effects that oil is pumped to the bottom of the piston by the oil hole, the piston rod moves, and is abutted against and pushes the locking wedge to slide along an inclined V-shaped groove, the clearance between the tool holder and the V-shaped groove of the tool rest connecting rod is increased to complete tool change, hydraulic oil is removed from the bottom of the piston, the locking wedge resets under the action of the dish spring and the tool holder is locked; and the mechanism is simple in structure, reliable in use, short in tool change time and high in production efficiency.
Description
Technical field:
The utility model relates to the steel rolling equipment technical field, particularly relates to a kind of bar flying shearing machine tool changing bearing retaining mechanism.
Background technology:
In the prior art, the big stick-means of intimidation flying shearing machine generally adopt planer type structure, and the tool rest of flying shearing machine generally is installed in the semi-enclosed structure; Can't as common flying shear, quick knockout screw carry out tool changing; This just makes that the tool rest retaining mechanism of big stick-means of intimidation flying shear is different with common flying shear, and flying shearing machine blade wearing and tearing in use are very fast, and the life-span of cutter is very short; The quick release tool rest carries out tool changing when how to make this cutter bearing retaining mechanism can cooperate cutter-exchange mechanism to realize tool changing; Back locking tool rest and guarantee equipment safe in utilizationly just become the problem that people are badly in need of solving at present, also do not have the bar flying shearing machine tool changing bearing retaining mechanism of practicality is fast accomplished in tool changing.
Summary of the invention:
The purpose of the utility model provides a kind of in the shear history of bar flying shearing machine, can be easy to operate, simple in structure, use reliable and can be in time when the tool changing of big stick-means of intimidation flying shearing machine, the tool changing bearing retaining mechanism of accurate, rapid changing knife.
The utility model solves the scheme that its technical problem adopted: a kind of bar flying shearing machine tool changing bearing retaining mechanism is provided, comprises casing, tool rest, characteristic is: also comprise knife rest connecting rod piston, screw-thread bush, locking wedge, dish spring, screw; The knife rest connecting rod is installed on the casing, and tool rest links to each other with the knife rest connecting rod through dovetail groove, and the locking wedge also is installed on the knife rest connecting rod, links to each other with the dovetail groove of tool rest simultaneously, and screw is fixedly connected with the knife rest connecting rod; The dish spring is through on the shank of screw, and an end withstands screw, and an end withstands the locking wedge; Screw-thread bush is installed on the knife rest connecting rod, and piston passes in the piston hole that screw-thread bush is installed in the knife rest connecting rod; Have oilhole on the knife rest connecting rod, link to each other with piston hole.
The beneficial effect of the utility model is: owing to buy oil to piston base through oilhole; Make and withstand piston rod movement and promote the locking wedge and slide along oblique V-type groove, the V-type groove gap of tool rest and knife rest connecting rod is strengthened and the completion tool changing; Remove the hydraulic oil of piston base; Make locking wedge return under the effect of dish spring, reduce the V-type groove gap of bearing and knife rest connecting rod, tool rest locking; This mechanism structure is simple, easy to adjust, use is reliable, tool change time is short, and production efficiency is high.
Description of drawings
Fig. 1 is the utility model embodiment " a kind of bar flying shearing machine tool changing bearing retaining mechanism " structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
In the accompanying drawing: 1. casing; 2. tool rest; 3. knife rest connecting rod; 4. piston; 5. screw-thread bush; 6. locking wedge; 7. dish spring; 8. screw.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is done further explain.A kind of bar flying shearing machine tool changing bearing retaining mechanism as shown in Figure 1 comprises interconnective casing 1, tool rest 2, knife rest connecting rod 3, piston 4, screw-thread bush 5, locking wedge 6, dish spring 7, screw 8; Knife rest connecting rod 3 is installed on the casing 1, and tool rest 2 links to each other with knife rest connecting rod 3 through dovetail groove, and locking wedge 6 also is installed on the knife rest connecting rod 3, links to each other with the dovetail groove of tool rest 2 simultaneously, and screw 8 is fixedly connected with knife rest connecting rod 3; Dish spring 7 is through on screw 8 bars, and an end withstands screw 8, one ends and withstands locking wedge 6; Screw-thread bush 5 is installed on the knife rest connecting rod 3, and piston 4 passes screw-thread bush 5, is installed in the piston hole of knife rest connecting rod 3; Have oilhole on the knife rest connecting rod 3, link to each other with piston hole.The operation principle of the utility model is: when the needs tool changing, can buy oil to piston 4 bottoms through oilhole, make and withstand piston rod movement and promote locking wedge 6 and slide along oblique V-type groove.This moment, tool rest 2 strengthened with the V-type groove gap of knife rest connecting rod 3, guaranteed that tool changing device can be with tool rest 2 extractions.After tool changing is accomplished, can remove the hydraulic oil of piston base, make locking wedge 6 return under the effect of dish spring, thereby reduce the V-type groove gap of bearing 2 and knife rest connecting rod 3, guarantee the locking state of tool rest when work.
