Description
Technical field
The utility model relates to a kind of percussion drill dust guard, belongs to percussion drill dust control technology field.
Background technology
Percussion drill is a kind of the most frequently used electric tool in the architectural engineering.Because percussion drill is not in use taked any measure that prevents the dust diffusion usually, thereby can produce a large amount of drilling cuttings dust, grievous injury health and surrounding environment.For a change this situation, people also did many trials, just once developed the easy dust exhaust apparatus that is enclosed within on the drill bit as German Bosch company, indivedual enterprises of Korea S also developed to have and blew and the cleaner of dust suction two-way function, and more domestic producers also did a lot of trials in this respect.Lv Yunsong teaches and has developed vapour-pressure type " percussion drill dust guard " in 2003, and has obtained utility model patent, the patent No.: ZL200320110381.6.Because manufacturing cost is higher, fails to enter the practical stage, does not also see the dust guard that is used on the percussion drill on the market always.Therefore, the percussion drill dust guard of developing a kind of practicality is a useful job.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, percussion drill dust guard that manufacturing cost is lower.
A kind of percussion drill dust guard is characterized in that:
Comprise dust arrester, and be used to connect dust arrester and make it and support compression device that metope compresses, also comprise being used for the support compression device is fixed in percussion drill rig erector on one's body;
Wherein the support compression device comprises front sleeve and the back sleeve that is nested together, and is installed on the compression spring in front sleeve and the back sleeve;
Wherein dust arrester is fixedly installed on the front sleeve, it comprises dust gathering arrester, be installed on median septum in the dust gathering arrester, be installed on the squab panel at dust gathering arrester rear, described dust gathering arrester is provided with the through hole that drill bit is passed through and can control of dust, and median septum is provided with through hole, squab panel that drill bit is passed through and is provided with the through hole that drill chuck is passed through.
During the percussion drill operation, the drilling cuttings dust leaks along helical flue of drill, stop dust to leak, just must guarantee to seal between dust gathering arrester and drill bit, in addition, in drill bit when rotation, is with strong axial vibration and radially wobble, therefore also must the solution drill bit and seal between the friction and wear problem.The utility model utilizes the support compression device to keep the position between dust gathering arrester and drill bit to concern, thereby prevents that dust from leaking from the dust gathering arrester rear portion.During the percussion drill operation, dust also can leak along metope, stop dust to leak, and just must guarantee the sealing between dust gathering arrester and metope, and in addition, the impulse stroke of percussion drill alters a great deal, and the long drill bit stroke is longer.In the process of boring, to guarantee that promptly dust gathering arrester and metope have enough contact forces to leak to prevent dust, can not make contact force excessive and influence normal operation again.The utility model adopts telescopic spring compression device, and spring has enough drifts, and relative compression amount changes not quite during operation, so can satisfy above-mentioned requirements.In order to guarantee to seal the dirt effect and to have certain storage dirt capacity, dust gathering arrester must have certain thickness, for reducing influence to drilling depth, in dust gathering arrester, be provided with median septum, can be divided into some shelves by diameter series with using drill bit always, determine the median septum aperture according to every grade of high limit of size, detachably replace in the median septum aperture.The electric drill chuck can pass through the dust gathering arrester rear wall and arrive at the dividing plate rear position, has increased maximum drilling depth.
Above-mentioned erector can adopt following structure: comprise that being installed on front sleeve and back is positioned at second branch sleeve on the sleeve in the outside in the sleeve, and be fixed on the hoop on the rig, also comprise being used for elasticity integrated circuit board that second branch sleeve is connected with hoop.By the elasticity integrated circuit board, support compression device and dust gathering arrester can be quickly installed on the percussion drill, can take fast after finishing to use.
Above-mentioned dust arrester is fixedly installed on the front sleeve and can realizes in the following manner: above-mentioned dust arrester also comprises first branch sleeve and carriage, first branch sleeve is installed on the front sleeve, carriage one end and first branch sleeve are connected, and the other end is connected with dust gathering arrester.
Above-mentioned first branch sleeve can be installed on the front sleeve in the following manner: the screw of a head chamfered edge is installed on the front sleeve, the first branch sleeve end face is provided with oblong aperture, when oblong aperture was alignd with chamfered edge screw head shape, above-mentioned first branch sleeve can freedom be inserted in or extract fast.Only need first branch sleeve is turned over certain angle, head of screw can be with its axial limiting.
Above-mentionedly can be connected by bearing pin with carriage at dust gathering arrester.Dust gathering arrester can be swung around bearing pin; Bearing pin is positioned at dust gathering arrester horizontal symmetry axis below, and bearing pin can adopt screw or rivet.Dust gathering arrester is connected by bearing pin with carriage, also can guarantee tight the contact even rig slightly tilts with metope.
Above-mentioned dust gathering arrester can be taked following shape, and the front portion is conical, and the rear portion is a cylindrical shape.It is to prevent that the dust secondary in the dust gathering arrester from leaking that front end adopts the conical surface.
