Description

A kind of multifunctional industrial hammer

Technical field

The utility model relates to the field of tool of factory, particularly a kind of multifunctional industrial hammer.

Background technology

At the particularly machine-building of many factories, Material Processing factories, be unable to do without a large amount of technological equipments, technological equipment is called for short " frock ".Frock dismounting technicians usually use cylindrical red copper bar as dismantling device.Because the hardness of the hardness ratio tool part material of red copper material is much lower, can prevent the strength member in frock from being struck wound like this.Frock technicians hand-held cylindrical red copper bar, to brandish up and down, utilize the momentum of copper rod to install and remove frock parts.But the momentum that technicians brandish copper rod, make copper rod obtain is very limited, and the arm of technicians easily tired, palm and arm are often shaken numb.

In addition, the standard components such as the screw in frock, bolt are more, when tightening or unclamp the hexagon socket cap head screw in frock, often need with steel pipe socket on inner hexagon spanner, realize the lengthening reversing the arm of force; And steel pipe inconvenience is placed, put and easily roll on the table.Further, in factory, the external diameter of the bolt that middle-size and small-size frock is the most frequently used is M10, M12, when tightening or unscrew these bolts, must use corresponding spanner or monkey wrench.

As can be seen here, the instrument that in copper rod, inner hexagon spanner, steel pipe, bolt and nut spanner Deng Shi factory, dismounting frock is conventional, copper rod uses very inconvenient.

Summary of the invention

The technical problems to be solved in the utility model is a kind of multifunctional industrial hammer of invention.

The technical solution of the utility model is: it is that same cylinder forms that the tup of hammer is the rod iron of 50 to 60 millimeters and red copper bar by gas welding or Welding by diameter, and rod iron length is 80 to 90 millimeters, and red copper bar length is 30 to 40 millimeters; The periphery plane that milling four is parallel with cylinder axis in the axial direction of tup, four planes are uniformly distributed along cylinder circumference, four planes are shorter than cylindrical radius 2 to 3 millimeters with the distance of cylinder axis, the effect of four planes be conveniently bore, the handle hole of ream hammer and dowel hole.

Upper and lower surface in the middle part of the tup of hammer is milling groove mouth respectively, and width of rebate is respectively than large 0.3 to 0.5 millimeter of M10, M12 hex nut across flats, and notch direction is vertical with the axis direction of hammer, and the degree of depth of notch is 7 millimeters.

The handle of hammer is made up of the steel pipe of diameter 30 to 35 millimeters, length 310 to 330 millimeters, wall thickness 4 to 5 millimeters; The cylindrical of handle one end wants the length of shorter than tup diameter 7 millimeters of turnery processing one section, handle to machined the length of endoporus turnery processing than long 3 millimeters of tup diameter of this one end of cylindrical; The manufactured cylindrical of handle and tup hole interference fit, the manufactured endoporus of handle puts into a Special purpose locating pin, handle endoporus and Special purpose locating pin interference fit; Special purpose locating pin plays a part to increase handle strength, long 5 millimeters of its effective length ratio tup diameter; After the handle of hammer and tup, Special purpose locating pin are worked good, then at the locating hole of the centre drill of tup, ream one diameter 12 or 16 millimeters, and squeeze into the steel drive pin of corresponding interference fit, steel drive pin length is shorter than tup diameter 20 millimeters; Steel drive pin squeeze into after in its one end electric welding, polish, itself and tup are welded together.The other end hot jacket one of hammer handle is long 80 millimeters, the rubber sleeve of wall thickness 5 millimeters, endoporus and handle cylindrical interference fit, shockproof when working for hammer user.

The beneficial effects of the utility model are: the mode that the technicians of factory hold hammer is comfortable, easy to operate; When with hammer dismounting, bumper's component, greatly can alleviate the degree that arm, palm are numb, tup can also obtain larger speed and momentum.When bumper loads onto the parts of important fearness distortion, beat by the red copper part of tup; When bumper loads onto and do not allow yielding parts, beat by the steel part of tup; Like this, both saved valuable red copper material, the service life of hammer can have been extended again.Further, tighten with inner hexagon spanner or unscrew external diameter be socket cap screw that M8, M10 etc. are conventional need sleeve time, can by the steel pipe handle of hammer; Needs tighten or unscrew external diameter be M10, M12 hex bolts or nut time, the groove of tup can be utilized.Therefore, this hammer integrates copper rod, rod iron, the function such as back-up wrench of anti-hand fiber crops, the sleeve of part inner hexagon spanner, part conventional screw bolt and nut when holding hammer steel components, very easy to use, reliable.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Detailed description of the invention of the present utility model is: the tup of hammer is 50 to 60 millimeters red copper bar (2) by diameter is that same cylinder forms with rod iron (3) by gas welding or Welding, rod iron (3) length is 80 to 90 millimeters, and red copper bar (2) length is 30 to 40 millimeters; The periphery plane that milling four is parallel with cylinder axis in the axial direction of tup, four planes are uniformly distributed along cylinder circumference, four planes are shorter than cylindrical radius 2 to 3 millimeters with the distance of cylinder axis, the effect of four planes be conveniently bore, the handle hole of ream hammer and dowel hole.

Upper and lower surface in the middle part of the tup of hammer is milling groove mouth respectively, and width of rebate is respectively than large 0.3 to 0.5 millimeter of M10, M12 hex nut across flats, and notch direction is vertical with the axis direction of hammer, and the degree of depth of notch is 7 millimeters.

The handle (5) of hammer is made up of the steel pipe of diameter 30 to 35 millimeters, length 310 to 330 millimeters, wall thickness 4 to 5 millimeters; The cylindrical of handle one end wants the length of shorter than tup diameter 7 millimeters of turnery processing one section, and the external cutting degree of depth is no more than 0.5 millimeter; Handle machined the length of endoporus turnery processing than long 3 millimeters of tup diameter of this one end of cylindrical, and endoporus cutting depth is also no more than 0.5 millimeter; The manufactured cylindrical of handle and tup hole interference fit, the manufactured endoporus of handle puts into a Special purpose locating pin (1), the manufactured endoporus of handle and Special purpose locating pin (1) interference fit; Special purpose locating pin (1) plays a part to increase handle strength, and it is longer than tup diameter 5 millimeters with steel tube inner hole length of fit; After the handle of hammer and tup, Special purpose locating pin are worked good, then at the locating hole of the centre drill of tup, ream one diameter 12 or 16 millimeters, and squeeze into the steel drive pin (4) of corresponding interference fit, steel drive pin (4) length is shorter than tup diameter 20 millimeters; Steel drive pin (4) squeeze into after in its one end electric welding, polish, itself and tup are welded together.The equal chamfering of inside and outside circle 0.5 to 1 millimeter that hammer is all.The other end hot jacket one of hammer handle is long 80 millimeters, the rubber sleeve (6) of wall thickness 5 millimeters, endoporus and handle cylindrical interference fit, shockproof when working for hammer user, anti-skidding.
