By using technique scheme, first, the introducing of fixed part, can increase and electric hammer is fixed, so, before electric hammer starts punching, observe the round end on electric hammer by transparent shield and adjust accordingly, it is allowed to the punch position that alignment is preset, positioning action now by location division, it is positioned related for electric hammer protective cover together to punch in plane, the round end preventing electric hammer offsets in vibrations, serve, only need to be fixed portion in punching plane by one end of the gripping on expansion link, the reliable location to protective cover and internal electric hammer round end can be realized；In addition, it is different from prior art, protective cover is set directly on the round end of electric hammer by bearing, the dust being possible to prevent punching falls into other positions of electric hammer, and, by the supporting role of bearing, it is ensured that the round end of electric hammer, relative to the running accuracy of protective cover, is conducive to improving drilling precision.
This utility model is further arranged to: described location division includes the locating detent arranged no less than three in not conllinear, described locating detent includes sucker and post, and described sucker is connected to the end of protective cover by post and forms a locating surface parallel with protective cover end face.
By using technique scheme, Set Theory by one plane of three-point fix, a locating surface is formed by three suckers, and make the round end of electric hammer expose locating surface, so, punch position can effectively be positioned by three suckers with the absorption affinity of drilling plane, and by the elastic deformation of post, in boring procedure, drill bit constantly pierces punching plane and completes boring action.
This utility model is further arranged to: described location division includes the elastic ring suitable with the face size of protective cover, and described elastic ring is provided with Access Division, and described elastic ring is fixed to the end face of protective cover by Access Division.
By using technique scheme, utilize the elasticity of elastic ring, by expansion link, elastic ring is pressed in punching plane, give the elastic ring one normal pressure towards punching plane, increase the friction between itself and punching plane, utilize this frictional force to prevent the skew of round end of electric hammer.
This utility model is further arranged to: described location division includes the sectional dimension sucker more than protective cover face size.
By using technique scheme, whole location division is made the sectional dimension sucker more than protective cover end face, can be in drill process, the drilling athletic meeting of the round end of electric hammer is gradually increased the absorption affinity of sucker and punching plane, thus ensure that the detent force of the structure of location division increases along with the vibrations of boring and increases, it is ensured that its locating effect.
This utility model is further arranged to: be provided with between described bearing and the round end of electric hammer for preventing dust from falling into the baffle plate in bearing.
By use technique scheme, owing to the rotating accuracy of bearing itself is higher, therefore, in order to prevent dust entrance Bearing inner, the baffle plate of increase can together with the bottom of protective cover the space of one opposing seal of next year process, prevent the dust pollution to bearing.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, this utility model is described further.
A kind of electric hammer assembly with repeatable location protective jacket, as shown in Figure 1, include expansion link 1, be arranged at the end of expansion link 1 for fixing support 2 and the electric hammer 3 of electric hammer, wherein, the length adjustment of expansion link 1 thus electric hammer 3 is lifted to different height, expansion link 1 can use the screwed bar in end of some sections to splice, it is possible to uses several sections of bars of socket to be slidably connected.Support 2 is located at the end of expansion link 1, and when erecting expansion link 1, support 2 carries out high-altitude punch operation with the electric hammer 3 being fixed thereon near punching plane.
Due to during the punch operation of high-altitude, workmen is the lower section standing in punch position, therefore, the dust produced in drill process can directly descend slowly and lightly around workmen, this is on the round end of electric hammer 3 and bearing 5 is provided with transparent shield 4, for blocking the dust produced in drill process.It is more than the opening size of itself and the junction of electric hammer 3 with enough spaces, the opening part size of transparent shield 4 to give the round end of electric hammer 3.
Further, in order to prevent the dust produced in drill process from falling in bearing 5, between bearing 5 and electric hammer 3, it is additionally provided with baffle plate 51, for blocking the dust of the round end from electric hammer 3, prevents this part dust from affecting the life-span of bearing 5.
Further, in drill process, the vibration of electric hammer 3 can affect the precision of punching, and therefore, in this utility model, the end at transparent shield 4 is provided with location division 6, for positioning electric hammer 3 reliably in drill process.
The embodiment 1 of location division 6
As shown in Figures 2 and 3, location division 6 includes at least 3 locating detents 61, according to 3 geometrical principles limiting a plane, three locating detents 61 form a location plane in the end of transparent shield 4, this location plane is vertical with the drill bit of electric hammer 3, ensure drill process limits the perpendicularity of the drill bit on electric hammer 3, prevent from boring partially.Locating detent 61 includes post 611 and the sucker 612 being arranged between post 611 and punching plane, when the position of electric hammer 3 alignment punching, promote expansion link 1, being allowed to be pressed in sucker 612 in punching plane, sucker 612 is adsorbed in punching plane, prevents the skew of transparent shield 4 and electric hammer 3, carrying out along with boring action, the slight compression of post 611, so that the drill bit drilling on electric hammer 3 is directly collected by transparent shield 4 to designated depth, the dust produced in boring procedure.
The embodiment 2 of location division 6
As shown in Figure 4, location division 6 includes the elastic ring 62 being arranged on transparent shield 4 end, and the size of elastic ring 62 is adaptive with the end size of transparent shield 4, and by Access Division 63 and transparent shield 4 clamping.In drill process, utilize the elasticity of elastic ring 62, by expansion link 1, the elastic ring 62 of transparent shield 4 end is pressed in punching plane, now, normal pressure on expansion link 1 makes to produce a frictional force between elastic ring 62 and punching plane, is prevented the vibration effect drilling precision of electric hammer 3 by this frictional force.Especially, the elasticity of elastic ring 62 is adapted to the drilling campaign of drill bit.
The embodiment 3 of location division 6
As it is shown in figure 5, the elastic ring 62 in embodiment 2 is replaced to end face sucker 64, now, the absorption principle of end face sucker 64 is in the same manner as in Example 1.The size of end face sucker 64 is identical with the end size of transparent shield 4, and the size of its one end being adsorbed in punching plane is more than the end size with transparent shield 4.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
