Abstract
The utility model discloses a multifunctional electric hammer having functions of a hammer, a hammer drill, and a drill. The utility model comprises a housing, a transmission shaft assembly, an impacting shaft assembly, a turn knob, a slide plate, and a fixing base of the impacting shaft. The utility model is characterized in that the slide plate is arranged in a vertical slot of the fixing base of the impacting shaft, the upper end of the slide plate is provided with a lug boss capable of pushing a slide gear, a side-push plate capable of pushing a clutch, and a turn knob pin hole capable of controlling three kind of states; an eccentric pin of the turn knob is inserted into the pin hole, and the front end of the impacting shaft assembly is sheathed with a restoring spring. The utility model has the advantages of compact structure, simple operation, reliable positioning, good safety performance, easy operation, and easy installation, and one switch controlling conversions of three kind of functions is realized conveniently.
Description
The utility model relates to a kind of electric hammer, particularly a kind ofly can be used for boring, the multifunctional electric hammer of hammer drill, three kinds of functions of hammer.
The function conversion of three function electric hammer is generally realized by two knob combinations, the engagement that knob is used to control balladeur train and power transmission shaft tooth on the impacting shaft with separate, the combination that another knob is used to control Oscillating lever bearing and power transmission shaft with separate, realize three kinds of function conversion thus, this version inconvenient operation, and knob combination a kind of state is arranged is neutral.An existing knob three function electric hammer is controlled Oscillating lever bearing with knob, slide plate control balladeur train, and the back-moving spring of balladeur train is installed on the slide plate.This structure back-moving spring location is unreliable, and reset response power drops on the slide plate poor stability.
The purpose of this utility model is to provide a kind of and realizes three kinds of functions conversions of electric hammer and reliable effect, multifunctional electric hammer easy to install by a knob.
The purpose of this utility model is achieved in that a kind of multifunctional electric hammer, it is made up of front end component and back-end component, front end component is the transmission control part branch, back-end component is power section, front-end and back-end connect with screw, front end component comprises front end shell, transmission shaft component, the impacting shaft assembly, knob, slide plate, the impacting shaft holder, impacting shaft assembly and transmission shaft component are installed on the impacting shaft holder, diaxon is at a distance of certain operating distance, it is characterized in that: slide plate is arranged in the vertical channel of impacting shaft holder, the slide plate upper end is provided with the knob pin-and-hole of the boss that can promote balladeur train and the side guide that promotes clutch and three kinds of duties of control electric hammer, the cam pin of knob inserts in the pin-and-hole, and the front end of impacting shaft assembly is with back-moving spring.
Principle of the present utility model is, the knob rotation, cam pin on the knob drives slide plate and is in three kinds of duties: when 1, slide plate mediates, balladeur train meshes with the power transmission shaft tooth under action of reset spring, clutch combines Oscillating lever bearing and power transmission shaft under the effect of clutch stage clip, can realize the hammer drill function; 2, move behind the slide plate, side guide is stirred clutch makes Oscillating lever bearing separate with power transmission shaft, realizes boring function; 3, slide plate reach, boss promote balladeur train and separate with power transmission shaft, and clutch resets under the effect of clutch stage clip, and Oscillating lever bearing combines with power transmission shaft, realize the hammer function.
The utility model compared with prior art, compact conformation, simple to operate, can realize the function conversion of electric hammer easily, the part major part all concentrates on impacting shaft assembly and the transmission shaft component, the location is reliable, installs and easy to use.
Fig. 1 is the structural representation of multifunctional electric hammer front-end control part of the present utility model.
Fig. 2 is the structural representation of slide plate of the present utility model and knob control section.
Fig. 3 is the A-A profile of structure shown in Figure 1.
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment: in conjunction with Fig. 1, Fig. 2, Fig. 3, the function electric hammer that the utility model is many, form by front end component and back-end component, front end component is the transmission control part branch, back-end component is power sections such as motor, front end component comprises housing 1, transmission shaft component 8, impacting shaft assembly 9, knob 10, impacting shaft holder 4, slide plate 11, on impacting shaft assembly 9, be provided with back-moving spring 2 and balladeur train 3, back-moving spring 2 usefulness axle-steel silk back-up rings 13 and back-up ring 14 location, Oscillating lever bearing 5 is arranged on transmission shaft component 8, clutch stage clip 6, clutch 7, back-moving spring 2 is used for balladeur train 3 and resets, clutch stage clip 6 is used for clutch 7 and resets, and a cam pin 12 is housed on the knob 10, and a slotted hole is arranged on the slide plate 11, cam pin 12 is inserted in the hole of slide plate 11, and cam pin 12 can drive slide plate 11 slippage in the groove 20 of impacting shaft holder 4.The slide plate upper end is provided with the knob pin-and-hole 19 of the boss 16 that promotes balladeur train 3 and the side guide 18 that promotes clutch 7 and three kinds of duties of control electric hammer, pin-and-hole is a horizontal direction, elongated hole, two ends are circular arc, and boss 16, side guide 18, slide plate 11 threes are vertical mutually.
