Description

Bench work hammering rod
Technical field
The utility model relates to a kind of bench work specific purpose tool, and the erecting tools that particularly when a kind of Automatic manual transmission or maintenance, pincers worker uses, belongs to small tool technical field.
Background technology
When the parts of plant equipment are installed, especially when the shaft hole matching of part assembles, damaging to prevent the component surface put in hole or produce distortion makes assembling be difficult to carry out, pincers worker adopts the hardness such as the brass bar of various diameter, electrolysis copper rod or hardwood rod to carry out the active force needed for transfer components installation, to ensure that the surface of mounted parts does not sustain damage lower than the hammering rod being assembled parts usually.Particularly when installing the part of the materials such as cast bronze, brass, aluminium alloy, babbit, because its hardness is lower, the hammering rod then needing to make specially the lower special substance of hardness, as power transmission instrument, is made troubles to the work of machine-building, installation and equipment repair.In addition, the hammering rod cost adopting the non-ferrous metal such as brass bar or electrolysis copper rod to make is higher.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, low cost of manufacture, flexible and convenient to use, can the bench work hammering rod that makes of seriation.
The utility model is achieved by the following technical programs:
A kind of bench work hammering rod, comprise the body section, changeover portion and the hammering head that are fixedly connected with in turn, the changeover portion small end of multidiameter shape is fixedly connected with by screw thread with body section one end, the non-hammering end of hammering head is fixedly connected with by interference fit with the large end counterbore of changeover portion, and described changeover portion small end is provided with the axial material returned through hole that end counterbore large with changeover portion communicates; Body section and changeover portion all adopt steel to make, and hammering head adopts hardness to be less than the non-ferrous metal of hammering object or nylon or bakelite or hardwood and makes.
The purpose of this utility model can also be realized further by following technical measures.
Aforesaid bench work hammering rod, in the middle part of wherein said body section, the diameter of handgrip part is less than two ends diameter, is provided with roll extrusion reticulate pattern in the middle part of body section; The large end outer peripheral face of changeover portion is provided with roll extrusion reticulate pattern.
Aforesaid bench work hammering rod, the non-hammering end of wherein said hammering head axially extends connecting axle, and described connecting axle is fixedly connected with by interference fit with the large end counterbore of changeover portion; The magnitude of interference between described connecting axle and the large end counterbore of changeover portion is 0.05 ~ 0.10mm.
The utility model take body section as unified reference for installation, changeover portion and hammering head are installed in turn in its one end, according to being assembled part actual conditions, if the force-bearing surfaces being assembled part is black skin or rough surface, then operator can utilize in the middle part of holding body section body section termination directly to knock as hammering end to be assembled part and to complete installation; Be the soft non-ferrous metals such as cast bronze, brass, aluminium alloy, babbit as being assembled part, then be assembled part with hammering head of the present utility model hammering, without the need to using the aids such as hammer, expanding the scope of application of the present utility model, reducing the service wear of hammering head.If installation heavy parts, be then force transfer body with the utility model, assist to install with sledgehammer hammering the utility model.Can also according to the difference being assembled part, be equipped with cylindrical hammering head or the tubular hammering head of multiple different-diameter, and aforementioned various different hammering head is contained in each self-corresponding changeover portion for subsequent use respectively, be assembled the axial workpiece that part is greater than 1 as draw ratios such as the discoid part such as bearing, gear or axle sleeves select different hammering heads according to different, flexible and convenient to use.The utility model adopts body section, changeover portion and hammering head syllogic assembly structure, can save the non-ferrous metal of more than 70%; And be provided with axial material returned through hole at changeover portion, to facilitate the hammering head removed and damage, greatly reduce manufacturing cost and use cost of the present utility model.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the structure diagram of the utility model embodiment one;
Fig. 2 is the partial structurtes sketch of the utility model embodiment two.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment one
As shown in Figure 1, the utility model comprise be fixedly connected with in turn body section 1, changeover portion 2 and hammering 3, body section 1 and changeover portion 2 all adopt steel to make, a hammering 3 employing hardness are less than the non-ferrous metal of hammering object as brass, cathode copper, aluminium alloy, or nylon or bakelite or hardwood etc. are made, in the middle part of body section 1, the diameter of handgrip part is less than the diameter at two ends, roll extrusion reticulate pattern 11 is provided with in the middle part of it, strengthen the frictional force of operator's handgrip part and body section 1, eliminate the potential safety hazard causing because frictional force is too small the utility model from operator's slippage on hand.Because changeover portion 2 is in multidiameter shape, changeover portion small end 21 is fixedly connected with by screw thread with body section 1 left end, and changeover portion large end 22 outer peripheral face is provided with roll extrusion reticulate pattern 11, to be screwed into by changeover portion small end 21 in body section 1 left end screwed hole 12.A hammering non-hammering end of 3 right-hand member of the present embodiment axially extends connecting axle 31, and described connecting axle 31 is fixedly connected with by interference fit with the large end counterbore 221 of changeover portion, and the described magnitude of interference is 0.05 ~ 0.10mm, guarantees both firm and reliable connection.Changeover portion small end 21 is provided with the axial material returned through hole 211 that end counterbore 221 large with changeover portion communicates, and is convenient to remove the hammering 3 damaged, and lowers use cost.
Embodiment two
As shown in Figure 2, the hammering of the present embodiment 3 is cylindrical, and described cylindrical right-hand member is fixedly connected with by interference fit with the large end counterbore 221 of changeover portion, and all the other structures are identical with embodiment one.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
