Description
Technical Field
The utility model relates to a horizontal machining center knife pouch technical field specifically is a change broach spring isolated plant.
Background
At present, a 15T horizontal machining center for Antian is installed in 2013 years, and after the cutter is used for 3-4 years, the phenomenon that the tension of a cutter sleeve in a cutter base is obviously insufficient is caused, so that heavy cutters often fall off in the cutter base. Later, the problem is found to be caused by the fact that the broach spring in the broach shell is easy to age and damage and can be solved by replacing the spring, but the replacement price of the broach library spring is extremely high, and all broach shells need to be replaced generally at regular intervals for 2-3 years, so that the maintenance cost is extremely high (the cost of accessories is more than 50 ten thousand yuan each time).
And, because the spring mounting is inboard at the cutter sleeve, the manual installation degree of difficulty is high, its mounted position is as shown in fig. 1, be the axle sleeve subassembly in the picture, set up outer round hole in the axle sleeve subassembly outside, pack spring and steel ball into outer round hole earlier during the installation, then plug up outer round hole with the hand, the spring is in the contraction state, put the axle sleeve subassembly into the cutter sleeve again, because the hand can't stretch into the cutter sleeve, the axle sleeve subassembly can only be filled in with it hard after entering the cutter sleeve, the installation time overlength, and the spring is very easily damaged (the spoilage exceeds 80%) when filling in, can't discover the damage after the spring installation is gone, can only discover through the later stage use, still can the unscheduled trouble appear when leading to the lathe to use.
SUMMERY OF THE UTILITY MODEL
The difficulty is changed in order to solve current broach spring, damages easily, problem with high costs, the utility model provides a change broach spring isolated plant, it can conveniently realize the change of broach spring, the phenomenon of damaging, reduce cost can not appear.
The technical scheme is as follows: the special device for replacing the broach spring is characterized by comprising a barrel, wherein a through connecting rod is arranged in the barrel in a sliding mode, a push plate is arranged at one end of the connecting rod, at least two spring pressing sheets are arranged on the outer wall of the barrel and located on one side of the push plate, and the end portions of the spring pressing sheets exceed the end portions of the barrel.
The spring pressing plates are further characterized in that the number of the spring pressing plates is three, three threaded holes are correspondingly formed in the outer wall of the sleeve, and the spring pressing plates are mounted on the outer wall of the barrel body through bolts and the threaded holes in a matched mode;
three groups of threaded holes are correspondingly formed in the outer wall of the cylinder body, each group of threaded holes comprises at least two threaded holes, and the spring pressing sheet is installed on the outer wall of the cylinder body in a matched mode through bolts and the threaded holes;
the push plate is fixed on the connecting rod through a screw;
a handle is arranged at the other end of the connecting rod;
the spring pressing sheet comprises a pressing sheet body and a pressing sheet tail portion, the thickness of the pressing sheet tail portion is smaller than that of the pressing sheet body, and the pressing sheet tail portion exceeds the end portion of the cylinder body.
Adopt the utility model discloses afterwards, after the outer round hole with steel ball and spring mounting on the axle sleeve subassembly, directly use isolated plant, in letting the spring preforming push down the axle sleeve subassembly after stretch into the sword cover, the spring can not receive the influence in the installation to can not take place the damage phenomenon, effectual the cost is reduced.

Detailed Description
Referring to fig. 2 to 5, the special device for replacing the broach spring comprises a cylinder body 1, wherein a through connecting rod 2 is arranged in the cylinder body 1 in a sliding mode, an end cover is arranged at 3 in the drawing, a first screw for fixing the end cover and the cylinder body is arranged at 4, a push plate 5 is arranged at one end of the connecting rod 2, the cylinder body 1 is opened at one end, three spring pressing sheets 6 are arranged on the outer wall of the cylinder body 1 and located on one side of the push plate 5, and the end portions of the spring pressing sheets 6 exceed the end portion of.
The outer wall of the barrel body 1 is correspondingly provided with three threaded holes, and the spring pressing sheet 6 is arranged on the outer wall of the barrel body 1 through the bolt 7 and the threaded holes in a matched mode; the push plate 5 is fixed on the connecting rod 2 through a second screw 8; the other end of the connecting rod 2 is provided with a handle 9, which is convenient for operation; the spring pressing sheet 6 comprises a pressing sheet body 6-1 and a pressing sheet tail part 6-2, the thickness of the pressing sheet tail part 6-2 is smaller than that of the pressing sheet body 6-1, the pressing sheet tail part 6-2 exceeds the end part of the barrel body 1, and the pressing sheet tail part is a thinner sheet.
Three screw holes of group have been seted up in the correspondence of 1 outer wall of barrel, and every screw hole of group includes two screw holes, and spring preforming 6 is installed in 1 outer wall of barrel through two bolts and screw hole cooperation, and the great condition of this kind of structure mainly used spring force when the unable centre gripping axle sleeve subassembly that stabilizes of first kind spring preforming 6, just needs the structure of using the second kind, ensures that the axle sleeve subassembly is by the centre gripping of stabilizing.
The use method of the special device for replacing the broach spring comprises the following steps:
(1) mounting the steel balls and the spring in an excircle hole on the shaft sleeve component, and then placing the steel balls and the spring inside a spring pressing sheet;
(2) pressing the spring pressing plate against the outer wall of the shaft sleeve assembly to fix the spring in the outer circular hole of the shaft sleeve assembly;
(3) the spring pressing sheet and the shaft sleeve assembly extend into a cutter sleeve of the equipment and reach a mounting position;
(4) the connecting rod is pushed to enable the push plate to push against the shaft sleeve assembly, the barrel and the spring pressing sheet leave the cutter sleeve, and the shaft sleeve assembly is left in the cutter sleeve to complete installation.
Because the shaft sleeve component is directly installed in place, the spring cannot be in contact with the inner wall of the cutter sleeve in the period, the damage phenomenon cannot occur, and the efficiency is high.
