    • 专利摘要:
    In a hand held power operated percussion tool, the housing (10) is vibration insulated from the impact mechanism to protect the operator from unhealthy vibration forces. In order to form a vibration damped grip means at or in front of the forward end of the tool housing (10), a sleeve element (20) is supported on the housing (10) for axial adjustability thereon. The sleeve element (20) surrounds the working implement (18) and prevents the operator from using the latter as a grip means. The sleeve element (20) is arrestable in any desired axial position by means of a conical lock nut (22) threadingly engaging the sleeve element (20) and forming therewith a radially acting clamping means.

    专利说明:

    The invention relates to manual pneumatic impact machines, which are used in mechanical engineering, construction and mining. A pneumatic tool is known that includes a housing with a handle and a barrel with a hammer and a working tool LJ in instruments of this type of operator supports it by clamping with one hand the back end of the housing: a tool, for example a handle, and with the other hand, gripping the front end of the tool In this type of tool, the problem of the harmful health effects of vibration on the operator’s hand is created. . The closest to the technical essence of the invention is a vibration-proof percussion machine, comprising a housing, a libie located therein an impact mechanism and a working tool mounted on the housing with the possibility of longitudinal movement of a hollow handle associated with the power source 2. The disadvantage of this machine is the difficulty of working with working tools of different lengths, increased vibration load on the operator's hand, holding the tool. The purpose of the invention is to provide convenience and increase safety when working with working tools of various lengths. This goal is achieved by the fact that the vibratory-smashed percussion machine, comprising a casing, a percussion mechanism and a working tool mounted on it, mounted on the casing with the possibility of longitudinal movement of a hollow handle, connected to a power source, is provided with a sleeve covering the working head. page and installed on the housing with the possibility of axial movement. In addition, the machine is equipped with a clamping device mounted on the sleeve and made in the form of a nut with an internal cone, cuts are made in the end of the sleeve, and at its end .. on the side of the slots there is a thread for tightening the nut. At the firm. 1 shows a side view of the machine with a partial tearing of the percussion instrument; in fig. 2 - sleeve in open position. The vibration-proof percussion machine includes a housing 1 with a percussion mechanism (not shown), a working tool 2 installed at the end of the housing 1, placed on the housing 1 with the possibility of longitudinal movement of a hollow handle 3 connected to a power source by means of fitting 4 and the trigger 5, the sleeve 6, covering the working tool 2 and mounted on the housing 1 with the possibility of axial movement on the cylinder 7 and fixing with a clamping device, made in the form of a nut 8 with an inner cone 9, in the end of the sleeve 6 there are cuts 10 and thread for screwing the nut 8. The cylinder 7 is moved along the body by means of a friction-movable ring 11. The working tool 2 is held on the body, 1 by means of a spring 12. The machine works as follows. After starting the machine, the percussion mechanism strikes the shank of the working tool 2. The sleeve 6 with the aid and the clamping device is fixed "in the cylinder 7 of the housing 1, the extension of the sleeve 6 is selected depending on the length of the working tool, thereby preventing the operator from vibration loads and improving conditions of work.
