Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, a portable turnover wrench for large-size tubular shaft parts includes a lever 4, a force applying rod 6 fixedly connected to one end of the lever 4, a lock catch 9 fixedly connected to the other end of the lever 4, and a positioning block 3 connected to the middle of the lever 4, wherein the lever 4 is rotatably connected to the positioning block 3, one end of the positioning block 3 is fixedly connected to one end of a hanging strip 1, a positioning portion 301 is disposed on the positioning block 3, the positioning portion 301 is used for contacting with a workpiece 2 to provide a supporting point and a positioning point through the positioning portion 301, the positioning portion 301 is fixedly connected to the positioning block 3, and may be detachably fixedly connected to the positioning block 3 or may be integrally formed with the positioning block 3, and the other end of the hanging strip 1 penetrates through the lock catch 9 and is fixedly connected to the lock catch 9.
The utility model discloses a portable upset spanner at first encircles suspender 1 at the surface of work piece 2, then fixes unfixed one end through hasp 9 to adjust suspender 1 through hasp 9 and encircle the length of work piece, with the tightness of ensureing to satisfy the upset requirement, thereby can adapt to the work piece 2 of arbitrary specification. After locking, when the stress application rod 6 is pressed downwards, the hanging strip 1 automatically holds the workpiece 2, and due to the positioning effect of the positioning block 3, the stress application rod 6 is pressed downwards to drive the workpiece 2 and the wrench to rotate clockwise, so that the purpose of overturning the workpiece 2 is achieved; correspondingly, when the force applying rod 6 is lifted up, the length of the hanging strip 1 surrounding the workpiece 2 is lengthened, so that the hanging strip 1 and the workpiece 2 are loosened, the positioning block 3 and the workpiece 2 start to slide relatively, the wrench rotates anticlockwise on the workpiece 2, the workpiece 2 does not move, and therefore, the purposes of overturning the workpiece 2 are finally achieved through the crossed pressing and lifting actions.
In one embodiment, the force applying rod 6 and the lever 4 are preferably fixedly connected in a detachable manner, for example, a threaded connection may be adopted, so that force applying rods 6 with different lengths can be selected according to workpieces 2 with different weights, so as to easily turn the workpieces 2.
As an embodiment, in order to have a suitable number of support points when the positioning block 3 contacts the workpiece 2, the side surface of the positioning portion 301 of the positioning block 3 contacting the workpiece 2 is grooved to form a V-shaped structure, as shown in fig. 2, the V-shaped structure can provide 2 support points, so as to better position the wrench on the workpiece 2, and facilitate the later turning of the workpiece 2. Simultaneously, the V-arrangement structure can not lead to taking place relative rotation between spanner and work piece 2 and the dead problem of card, and the arc structure then leads to when lifting the application of force pole easily, spanner and the dead problem of work piece card are unfavorable for the operation of overturning the work piece.
As an embodiment, in order to facilitate replacement of the hanging strip 1, the positioning block 3 and the hanging strip 1 are fixedly connected through a fixing pin 7.
As an embodiment, in order to facilitate the rotation between the lever 4 and the positioning block 3, the lever 4 and the positioning block 3 are rotatably connected through a rotating pin 8 to form a rotating lever mechanism, when the force applying rod 6 is lifted up, the latch 9 of the lever 4 moves downward, the length of the hanging strip 1 surrounding the workpiece 2 is lengthened and released, and conversely, when the force applying rod 6 is pressed down, the latch 9 of the lever 4 moves upward, and the length of the hanging strip 1 surrounding the workpiece 2 is shortened and tightened.
As an embodiment, the lock catch 9 is provided above one end of the lever 4 to restrict the movement of the strap 1 in the axial direction of the lock catch 9.
As an embodiment, the lock 9 is an oblique zigzag gate structure, that is, the lock 9 is provided with a zigzag gate 5, as shown in fig. 3 and 4, when the unfixed end of the sling 1 moves towards the direction of the force applying rod 6, it can freely pass through, and when the sling 1 moves towards the opposite direction, because the lock 9 is an oblique zigzag gate structure, the moving sling 1 drives the lock 9 to rotate, so that the lock 9 automatically locks the sling 1, and at this time, the sling 1 can only be released from the locking state after being unlocked by rotating the lock 9.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
