Abstract
The present utility model relates to a drill bushing disassembling tool, a U-shaped frame and a V-shaped frame are fixed by connection pin bolts, a connecting bar is firstly positioned in a hole of ahollow screw rod and can rotate freely in the hollow screw rod, the hollow screw rod is installed in a threaded hole in the middle of the U-shaped frame, and then, the connecting bar is welded together with a wedge, therefore, when a handle is rotated, the connecting bar and the wedge does not rotate with the hollow screw rod. The using method comprises installing a drill head or a drill bushing in a V-shaped groove of a V-shaped seat, installing the U-shaped frame, inserting the connection pin bolts of the U-shaped frame in the holes at the two sides of the V-shaped seat, adjusting the positioned of the drill bushing drill bushing to make a flat slotted hole aim at the wedge, rotating the handle to make the hollow screw rod drive the connecting bar and the wedge to move downwards and makeflat ends of the wedge and the drill bushing contact, rotating the handle continuously to drive the wedge to move downward continuously and ejecting a small drill bushing from a big drill bushing.
Description
Technical field
The utility model relates to the manual teardown instrument, specifically a kind of drill bushing extracting tool.
Background technology
In machining,, need drill bushing diversified in specifications to cooperate processing because the bore diameter difference can not directly cooperate drill bit sometimes with tailstock or drill press spindle hole.Dismounting commonly used is that the drill bushing of the specification that varies in size that will be assembled together beats on the ground with wedge, and poor fit is caused on fragile drill bit and drill bushing surface, influences borehole accuracy.For this reason, designed a kind of drill bushing extracting tool.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to operate, drill bushing extracting tool that cost is low is provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of drill bushing extracting tool comprises U-shaped frame and V-shape base, and the U-shaped frame is located by being connected pin with V-shape base, and hollow leading screw is installed in the middle screwed hole of U-shaped frame.
Connecting rod is put into earlier in the hole of hollow leading screw, and connecting rod can freely rotate in hollow leading screw, and connecting rod one end and wedge weld together.
Connecting rod of the present utility model is put into earlier in the hole of hollow leading screw, and connecting rod can freely rotate in hollow leading screw, then hollow leading screw is installed in the middle screwed hole of U-shaped frame.After the installation, connecting rod and wedge are welded together.When turning handle, connecting rod and wedge do not rotate with hollow leading screw like this, and the U-shaped frame is located by being connected pin with V-shape base.During use, the drill bit that will dismantle or drill bushing are placed in the V-shaped groove of V-shape base.The U-shaped frame is installed, the connection pin on the U-shaped frame is inserted in the hole of V-shape base both sides.Adjust the position of drill bushing, make the flat slotted eye of drill bushing aim at wedge.Turning handle, hollow leading screw drivening rod and wedge move downward, and make the tang contact of wedge drill bushing, are rotated further handle, and wedge continues to move down, and little drill bushing is ejected from big drill bushing.
The characteristics that this extracting tool has is simple in structure, easy to operate, the life-span is long.
Description of drawings
Fig. 1 is the structural representation of the utility model drill bushing extracting tool;
The structural representation that Fig. 2 places on V-shape base for drill bushing;
Fig. 3 is the structural representation of hollow leading screw, connecting rod, wedge;
Among the figure: 1, connect pin; 2, U-shaped frame; 3, handle; 4, hollow leading screw; 5, V-shape base; 6, drill bit; 7, little drill bushing; 8, big drill bushing; 9, connecting rod; 10, wedge.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1-Figure 3, U-shaped frame 2 is located by being connected pin 1 with V-shape base 5, and hollow leading screw 4 is installed in the screwed hole of U-shaped frame 2 centres.
Connecting rod 9 is put into earlier in the hole of hollow leading screw 4, and connecting rod 9 can freely rotate in hollow leading screw 4, and connecting rod 9 one ends and wedge 10 weld together.
Connecting rod 9 of the present utility model is put into earlier in the hole of hollow leading screw 4, and connecting rod 9 can freely rotate in hollow leading screw 4, then hollow leading screw 4 is installed in the screwed hole of U-shaped frame 2 centres.After the installation, connecting rod 9 and wedge 10 are welded together.When turning handle 3, connecting rod 9 and wedge 10 do not rotate with hollow leading screw 4 like this.2 ends of thread that connect pin 1 are connected with U-shaped frame 2 respectively, and U-shaped frame 2 is located by being connected pin 1 with V-shape base 5.During use, the drill bit 6 that will dismantle or big drill bushing 8 are placed in the V-shaped groove of V-shape base 5.U-shaped frame 2 is installed, the connection pin 1 on the U-shaped frame 2 is inserted in the hole of V-shape base 5 both sides.Adjust the position of big drill bushing 8, make the flat slotted eye of big drill bushing 8 aim at wedge 10.Turning handle 3, hollow leading screw 4 drivening rods 9 and wedge 10 move downward, and wedge 10 is contacted with the tang of bradawl cover 7, are rotated further handle 3, and wedge 10 continues to move down, and bradawl can be overlapped 7 and eject from big drill bushing.This extracting tool is simple in structure, easy to operate, the life-span is long.
