Abstract

The utility model relates to a hand hammer for mounting and dismounting a coupler. The hand hammer comprises a slide bar, a stress weight and a pull hammer, wherein one end of the slide bar is provided with a working head, and the other end of the slide bar is provided with a handle; the stress weight is arranged on the inner side, which is close to the handle, of the slide bar; the pull hammer is arranged on the slide bar and positioned between the working head and the stress weight; the working head comprises a C-shaped frame with a hammer head or a pull head with a notch, the pull hammer does back-and-forth axial motion in the unit length of the slide bar through manual operation and further impacts the stress weight, the stress weight transmit force to the hammer head of the C-shaped frame or the notch of the pull head through the slide bar and the C-shaped frame or the pull head, and finally acting force is applied to a bolt in the axial direction by the hammer head or the notch of the pull head, so that the bolt can be simply and quickly dismounted and mounted on the condition that the bolt is not damaged.

Description

A kind of installation and removal shaft coupling pull hammer

Technical field

The utility model relates to a kind of installation and removal instrument, particularly a kind of instrument of installation and removal shaft coupling.

Background technology

Because the braked wheel shaft coupling is mounted on the power shaft of reductor, wherein the braked wheel shaft coupling is to be connected by a circle articulation bolt, and strand drilling bolt is often comparatively compact with cooperating of strand drilling, so must rely on hand hammer to hit installation or removal.Because the distance of braked wheel shaft coupling and reductor is less and receive due to the structure of braked wheel, employed common hand hammer instrument can't be put to good use at narrow space usually, and is very difficult when the installation and removal bolt.

Fig. 1 and Fig. 2 have shown existing reductor 1 and the mounting structure form of braked wheel shaft coupling 2 and the method for present assembling-disassembling bolt.

As shown in Figure 1; Owing to must dismantle and install a circle articulation hole bolt 3 when replacing or maintenance shaft coupling; Receive the space narrow and small due to, common hand hammer can't hit from the axis direction of bolt, hand hammer can only obliquely hit through 4 pairs of bolts of striking bar from what have living space.

As shown in Figure 2, the arrow F among the figure representes the oblique direction of passing through the hitting power of 4 pairs of bolts of striking bar of common hand hammer, and the construction method of this assembling-disassembling bolt tends to cause the flexural deformation of bolt.

Summary of the invention

The purpose of the utility model provides a kind of hammer that pulls of installation and removal shaft coupling; Be used in dismounting and installation braked wheel shaft coupling process, bolt being carried out dismounting; Can make the dismounting of bolt limit by factors such as braked wheel structure and space be narrow and small; Thereby make assembling-disassembling bolt become rapidly simple, and can not cause bolt flexural deformation.

According to above-mentioned purpose, the utility model provides a kind of hammer that pulls of installation and removal shaft coupling, is provided with working head, stressed top on the slide bar of hammer and draws parts such as hammer pulling; This working head comprises C type frame or pulls out head; Wherein C type frame comprises a tup, pull out head and comprise a recess, through draw hammer on the slide bar unit length through manually doing round axial-movement; And then impact top; Stressed top is through slide bar and through C type frame or pull out the recess that first power is delivered to the tup of C type frame or pulls out head, and final tup or recess form active force to the axis direction of bolt, and then can simply promptly and under the situation of not damaging bolt carry out dismounting to bolt.The hammer that pulls of the utility model comprises:

One slide bar, the one of which end is provided with a working head, and the other end is provided with one handle;

One stressed top is located on the said slide bar inboard near handle;

One draws hammer, slides and to be located on the slide bar between working head and stressed top.

Preferably, said working head is a C type frame, and an end of C type frame is fixedly connected with an end of slide bar, and the other end of C type frame is fixed with a tup on the one side of slide bar, this tup be provided with one be used for the receive bolts head counterbore.

Preferably, said working head is to pull out head, and this pulls out head and is provided with a recess, is used for the screw rod of stud bolt.

The utility model pull hammer owing on slide bar, be provided with and comprise C type frame or pull out working head, the stressed top of head and draw parts such as hammer that wherein C type frame comprises a tup, pulls out head and comprises a recess; Through draw hammer on the slide bar unit length through manually doing round axial-movement; And then the impact top, stressed top is through slide bar and through C type frame or pull out the recess that first power is delivered to the tup of C type frame or pulls out head, and final tup or recess can form active force to the axis direction of bolt; Compared with prior art; The pulling hammer and can make assembling-disassembling bolt become simple to improve dismounting efficient rapidly of the utility model, and can not cause the flexural deformation of bolt.
