Abstract
The utility model discloses a three-functional electric hammer, which is mainly composed of a hammerhead body and a machine shell and a handle connected with the hammer body, wherein, the head of a shell body is provided with a drill clamping part, and is also provided with a cylinder body member and an impact hammer member; a single-phase series exciting motor is arranged in the machine shell; the head of the hammerhead body is also provided with a teleflex member; the teleflex member is designed into an SDS type structure of two-pit and two-key; a clutch device is arranged between the cylinder body member and the impact hammer member; a selecting knob connected with a crank linkage mechanism is arranged outside a speed-reduction box. The utility model has the advantages of safety, less noise, large torque and long service life, which can be widely used in construction project industry.
Description
The utility model relates to a kind of three function electric hammer.
Along with the development of domestic and international construction market, electric hammer is commonly used as building worker's instrument.But the electric hammer of Shi Yonging in the market, its major defect is that function is few, and rotating speed is slow, and service life is short, the safe insulation poor performance.
The purpose of this utility model is at above-mentioned shortcoming, provide a kind of scientific and reasonable for structure, good insulation preformance, it is the SDS type structure that pivoted housing parts head is designed to two holes, two keys, go for external drill bit structure, chucking power is strong, can not put and shake, as long as the conversion knob position just can reach and select action to touch the three function electric hammer of formula.
The utility model is a three function electric hammer, mainly reaching the casing that links to each other with reduction box by the tup body forms, the head of tup body is provided with the drill bit hold assembly, and be provided with the block stamp parts and contact with it, be provided with cylinder block sub-assembly in the tup body, be provided with single phase series motivated motor in the casing, described tup body head also is provided with the pivoted housing parts, it is the SDS type structure that the pivoted housing parts are designed to two holes, two keys, between cylinder block sub-assembly and block stamp parts, be provided with arrangement of clutch, arrangement of clutch is by being located at the outer clutch knob control of housing, and the reduction box rear side also is provided with the selection knob, select knob respectively be located at reduction box in crank connecting link link to each other with change-speed gearing.
The utility model compared with prior art has following distinguishing feature and good effect.(1) to be designed to two holes, two keys be the SDS type structure to pivoted housing parts head, goes for external drill bit structure, and folder skill power is strong, can not put and shake, and domestic electric hammer does not still have this form.(2) arrangement of clutch is provided with different parts, thereby selects required pattern: rotation adds impact, one-shot hits.(3) select the setting of knob, convertible knob position makes connecting rod produce rotation or does not change, and to reach the selection pattern: rotation adds impacts, single turning effort, makes electric hammer produce three different patterns with the cooperation of arrangement of clutch parts, belongs at home and initiating.(4) a pair of helical teeth and a pair of Gleason circular arc hammer gear is adopted in the setting of reduction box, stable drive, and torque is big, noise is little.(5) the utility model adopts double insulation, and is safe and reliable.
The utility model is applicable to builds industrial and commercial bank's industry.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is the utility model overall structure cut-away view,
As shown in the figure, the utility model mainly is made up of with the casing 2 that links to each other with housing reduction box 12 tup body 1, and the head of tup body 1 is provided with drill jig gripping member 3, is provided with block stamp parts 5 simultaneously and contacts with drill jig gripping member 3, also is provided with cylinder block sub-assembly 8 in the tup body 1.The head of described tup body 1 also is provided with pivoted housing parts 4, and it is the SDS type structure that pivoted housing parts 4 are designed to two holes, two keys, is provided with arrangement of clutch 7 between cylinder block sub-assembly 8 and block stamp parts 5, and arrangement of clutch 7 is provided with clutch knob 6.The single phase series motivated motor 11 that is provided with in the described casing 2 is connected with reduction box 12.Also be provided with respectively the selection knob 10 that links to each other with toggle 9 with reduction box 12.Toggle 9 joins with cylinder block sub-assembly 8.
At work, armature spindle outputting power by single phase series motivated motor passes through double reduction, make the drill bit workpiece obtain to be fit to build the working speed that the worker bores, another is passed through to the gear driven eccentric shaft in the centre, make the displacer in the cylinder block sub-assembly reciprocating in cylinder through the crank connecting rod, variation by the air chamber volume, make in the cylinder another piston in same cylinder body, do reciprocal ballistic motion, make the worker that builds in the drill bit workpiece bore and obtain having rotary cutting that the energy of impact is arranged again construction material with displacer.
The utility model is applicable to builds industrial and commercial bank's industry.
