Abstract
The invention discloses a handhold hammer drill machine tool. The handhold hammer drill machine tool comprises a machine body, a machine case, a driver, a hammering system and a cutter clamping system, and is characterized in that a double-layer bevel gear structure and an eccentric unit fixed on a middle shaft are also arranged in the machine case; the driver is connected with a large gear of the cutter clamping system by one layer of the bevel gear of a double-layer bevel gear structure; one layer of the bevel gear is connected with a gear of the driver; the front section of an impactor of the hammering system is an impact hammer; a hollow cavity is formed at the back section of the impactor; and the eccentric unit is positioned into the hollow cavity of the impactor. The handhold hammer drill machine tool is driven by using the double-layer bevel gear structure instead of the conventional multiple groups of gears; and meanwhile, and a cylinder piston is driven by using the eccentric unit on the middle shaft instead of the traditional swinging rod or an eccentric connecting rod, so that the handhold hammer drill machine tool has a simple and compact structure and is light and ingenious and flexible to work, and a person feels comfortable during holding the handhold hammer drill machine tool.
Description
Technical field
The present invention relates to the hand-held hammer drill toolroom machine of a kind of hammering fragmentation or rotary cutting working medium.
Background technology
At present, known hand-held hammer drill toolroom machine is to promote to impact sub the reciprocating motion, realization hammering, thereby broken working medium by the piston compression gas medium that fork drives in cylinder or the eccentric ratio driving cylinder on the one hand; To drive the rotation of holding cutter system by gear or axle to realize cutting working medium on the one hand; But this hand-held hammer drill toolroom machine is very complicated and heavy, and is uncomfortable and dumb when gripping work.
Summary of the invention
In order to overcome the complicated and heavy shortcoming of present hand-held hammer drill machine tool structure, the object of the present invention is to provide a kind of simple in structure and light and handy hand held power machine.
The technical solution used in the present invention is: a kind of hand-held hammer drill toolroom machine, include body, casing, driver, hammering system, knife clamping system, it is characterized in that: in casing, also be provided with bilayer cone toothing and an eccentric unit that is fixed on the jackshaft, described driver is connected with the gear wheel of knife clamping system by one deck cone tooth of double-deck cone toothing, and one deck cone tooth is connected with the gear of driver; The sub-leading portion of impact of described hammering system is jump bit, and back segment has a cavity; Described eccentric unit is positioned at the cavity that impacts son.
Described eccentric unit is a cam structure, is fixed on the jackshaft by pin.
The inwall front end of the sub-cavity of described impact is provided with convex surface, and rear inner wall is provided with concave curved surface.
A bilayer cone toothing with two-layer bevel gear is adopted in transmission of the present invention, bores tooth by the output gear of driver with the upper strata of double-deck cone toothing and cooperates, and drives the rotation of double-deck cone toothing.Double-deck cone toothing passes to the with it jackshaft of close-fitting with torsion on the one hand, so that jackshaft rotation, thereby drive eccentric finite element rotation, the two curved surfaces bump of the curved surface of eccentric unit and impact or extruding can realize impacting sub-acceleration forward and reset, impact son and accelerate can clash into tool shank forward, thereby so that the broken working medium of cutter; Lower floor's cone tooth of the double-deck cone of one side toothing cooperates with the gear wheel on being installed in the holding cutter system, rotates thereby drive gear wheel, drives the tooling system rotation, so that cutter rotary cutting working medium.
The present invention is by adopting a bilayer cone toothing with two-layer bevel gear to replace the transmission of former multiple sets of teeth wheel, double-deck cone toothing is realized the cutting function of cutter on the one hand by the transmission of cone tooth, impact son by the eccentric unit drives on the jackshaft on the other hand and realize the hammering function, fork before replacing or eccentric ratio drive cylinder piston and promote to impact son, thereby simple and compact for structure, portable and smart, when gripping work the people feel comfortable and work flexibly.

The specific embodiment
The present invention is further described below in conjunction with accompanying drawing and case study on implementation.
From Fig. 1,2 as can be known, hand-held hammer drill toolroom machine of the present invention includes body 1, casing 18, driver 2, hammering system, knife clamping system, also is provided with bilayer cone toothing 10 and an eccentric unit 4 that is fixed on the jackshaft 11 in casing 15; Lower floor's cone tooth 14 of double-deck cone toothing is connected with the gear wheel 7 of knife clamping system, and upper strata cone tooth 13 is connected with the gear 3 of driver; The hammering system comprises that one impacts son, impacting sub-leading portion is jump bit, and back segment has a cavity, and eccentric unit is positioned at and impacts sub-cavity, rotation by eccentric unit is so that eccentric unit bump or pinch shock realize impacting seesawing of son, thereby realizes the hammering function.Knife clamping system comprises holding cutter structure 8, gear wheel 7 and cutter 9.
From Fig. 3,4 as can be known, impact son 6 and be bearing in the holding cutter unit 8, impacting sub-leading portion is jump bit, and back segment has a cavity, and the inwall front end of its cavity is provided with convex surface, and rear inner wall is provided with concave curved surface.Eccentric unit 4 is a cam structure, is arranged in the sub-cavity of impact of hammering system.
More than show and described basic principle of the present invention and principal character and advantage of the present invention; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
