Description

Chuck mode is unloaded the top spanner

Technical field:

The utility model relates to the hardware ﹠ tools technical field, is that a kind of chuck mode is unloaded the top spanner specifically.

Background technology:

In actual production process; run into the situation that needs the dismounting screw thread through regular meeting; as needing to change the top of punching machine post rod in the steel pipe's production process; the existing pipe wrench of Sheng Chaning; in the instrument of dismounting such as chain wrench screw thread; because of moment of torsion little; the specific purpose tool that is not fit to the dismounting top; usually adopting the extra large size pipe wrench to block the top dismantles; but the screw thread of top is owing to expand at poling process stress deformation and high temperature; be difficult to dismounting, producers adopt sledgehammer to knock vibrations tops earlier, and the sleeve pipe that adds more than two meters of two or three human pipe wrench is dismantled then; and so forth; still some is difficult to dismounting at last, has to handle with gas cutting, delays the production time; increase working strength of workers, wasted the energy simultaneously.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and provides a kind of chuck mode to unload the top spanner, has mainly solved problems such as existing dismounting equipment top is difficult, the take-down time is long, working strength of workers is big, waste energy.

To achieve these goals, the utility model is achieved in that chuck mode unloads the top spanner, it comprises spanner housing 1, its special character is to establish hammer point 8 on spanner housing 1, establishes catch jacket 2 on spanner housing 1, and the inner bottom part of catch jacket 2 is established movable jaw 3, circle-arc tooth 4 is established in the bottom of movable jaw 3, establish screw rod 5 in movable jaw 3, movable jaw 3 can move up and down along screw rod 5, establishes stationary jaw 6 on the inner periphery of spanner housing 1.

Chuck mode of the present utility model is unloaded the top spanner, and its described stationary jaw 6 is two.

Chuck mode described in the utility model is unloaded the top spanner and is compared with the prior art had following good effect: 1, adopt the circle-arc tooth of three claws and the mode that screw thread clamps, frictional force between extracting tool and the workpiece is increased, easy problem of slip when having overcome dismounting has the larger clamping force square; 2, designed hammer point on spanner, original vibrations, two work steps of dismounting are united two into one, the top of ∮ 160-192mm can normally be dismantled, and need not employ gas cutting tool, has saved downtime, and the impulsive force that hammering produced is very big, and the dismounting effect is obvious; 3, all can change after the wearing and tearing of the circle-arc tooth of three claws, reduce waste; 4, reduce working strength of workers, saved the energy.

Description of drawings:

Fig. 1---structural representation of the present utility model.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment detailed description the utility model chuck mode below in conjunction with accompanying drawing and unload the top spanner.

Embodiment 1, referring to Fig. 1, be processed into spanner housing 1, on the inner periphery of spanner housing 1, fixedly mount two stationary jaws 6 with bearing pin 7, stationary jaw 6 bottoms are processed with circle-arc tooth, catch jacket 2 is installed on spanner housing 1, the movable jaw 3 of screw rod 5 is installed at the inner bottom part of catch jacket 2, movable jaw 3 can move up and down along screw rod 5, the bottom of movable jaw 3 is processed with circle-arc tooth 4, fixing welding hammer point 8 on spanner housing 1, the hammering direction of hammer point 8 is identical with the direction of three claw chuckings of spanner.

Chuck mode described in the utility model is unloaded the top spanner, during use, earlier spanner is enclosed within on the top, turn the square toes screw rod in the movable jaw, depress movable tooth, chucking top cylindrical, with the hammer point on the direct striking wrench of sledgehammer, produce turning moment, thereby unload the top.

Claims (2)

1, chuck mode is unloaded the top spanner, it comprises spanner housing (1), it is characterized in that on spanner housing (1), establishing hammer point (8), on spanner housing (1), establish catch jacket (2), the inner bottom part of catch jacket (2) is established movable jaw (3), and circle-arc tooth (4) is established in the bottom of movable jaw (3), establishes screw rod (5) in movable jaw (3), establish stationary jaw (6) on the inner periphery of spanner housing (1), circle-arc tooth is established in the bottom of stationary jaw (6).

2, chuck mode according to claim 1 is unloaded the top spanner, it is characterized in that described stationary jaw (6) is two.
