Abstract
The utility model relates to a hand-held band type polishing machine used for processing a complex surface, comprising a machine frame (1), a motor assembly (2) in the machine frame, a transmission mechanism (4), and an abrasive band tightening and deflection adjusting mechanism (3). An abrasive band (15) is driven by a motor (2) through the transmission mechanism (4) which is composed of driving and driven rollers (13) and (24) to carry out grinding and processing on a workpiece surface. The abrasive band tightening and deflection adjusting mechanism (3) comprises an eccentric adjusting nut (25), an adjusting rod (26), an adjusting frame (19) and a deflection adjusting screw (20). The driving roller (13) can also form a dust suction device (5) through a dust suction wind vane (12) which is fixedly connected. The hand-held band type polishing machine used for processing a complex surface more conveniently and accurately installs and replaces abrasive bands. A unique dust suction and collecting device improves working environment.
Description
The utility model relates to a kind of electronic grinding tool, especially for the hand-held belt sander of complex surface processing.
Sander is to all kinds of metalworks, nonmetal parts carries out the instrument of sanding surface, also be widely used in indoor and outdoor construction and decoration and machining, existing sander mainly is the plane sander, be used for processing large-area planar, but when practical application, usually need to be processed with the workpiece of complex surface, as mould, the five metals element, weldment, plated item etc., patent CN2032924U discloses a kind of " the portable resinder " that can process complex surface, but its abrasive band strainer structure is perfect inadequately, can only after shutdown, just can regulate, can not regulate tensioning abrasive band (abrasive band is elongated because of heating easily when work) in working order down, and the governor motion of not rectifying a deviation, more there is not dust exhaust apparatus to improve working environment.
The purpose of this utility model provides a kind of hand-held belt sander that has more perfect abrasive band strainer and have the correction regulatory function with regard to being for the defective that overcomes above-mentioned prior art.
Another purpose of the present utility model is to provide a kind of hand-held belt sander with dust suction, dust collection function.
Scheme of the present utility model is: hand-held belt sander comprises transmission mechanism and abrasive band tensioning and the adjusting deviation device that motor assembly, master, passive cylinder and the endless abrasive belt in frame, the frame constitutes; Described motor output end is directly installed drive roll, is mounted on passive cylinder on the roller shelves by the abrasive band; Tensioning of described abrasive band and adjusting deviation device are between drive roll and passive cylinder, comprise eccentric adjusting nut and adjusting rod thereof, adjusting bracket and tuningout screw, adjusting bracket and adjusting rod are connected and are supported on the frame by spring, adjusting bracket and roller shelves are connected as a single entity by the tuningout screw and are supported by the little spring of centre, together move forward and backward by rotation eccentric adjusting nut drive adjusting rod, adjusting bracket, roller shelves, passive cylinder, so that install and remove, the tuningout in abrasive band then can be realized by the interval of rotating between tuningout screw adjusting adjusting bracket and the roller shelves with the degree of tightness abrasive band.
The dust suction fan blade that can on described drive roll, be connected, and be positioned at by the plane seam and dust shield to be installed on the casing to form suction box, and open the dust mouth at Qi Bi and connect dust bag and reach dust suction, control of dust purpose.
The utility model compared with prior art compact conformation, installation is changed the abrasive band conveniently accurately, and unique dust suction, dust collect plant improved former sander dirt greatly and considered the working environment that flies upward to be worth doing, increases work efficiency.
Description of drawings.
Fig. 1 is the utility model overall appearance front view.
Fig. 2 is a structure cutaway view of the present utility model.
Below with reference to the accompanying drawings embodiment the utility model is described in further detail.
As shown in Figure 1, 2, hand-held belt sander comprises motor assembly (2), transmission mechanism (4), abrasive band tensioning and adjusting deviation device (3) and the dust exhaust apparatus (5) in frame (1), the frame;
So that formation is located and be screwed to the open plane seam, motor (2) is anterior to be fixed with cover plate (16) by screw (17) to frame (1) by casing (6), (27).Motor (2) is made up of rotor (14), stator (9) and brush (8), transmission mechanism (4) is made up of drive roll (13), passive cylinder (24) and the endless abrasive belt that is connected the two (15), rotor (14) output is connected with drive roll (13) tight fit, and passive cylinder (24) is installed in roller shelves (21) and goes up and locate with straight pin (23); Motor rotates during work, by rotor (14) output with transmission of power to drive roll (13), (15) rotate passive cylinder (24) synchronously through the abrasive band again, realize the transmission overall process.
Tensioning of described abrasive band and adjusting deviation device (3) are positioned between drive roll (13) and the passive cylinder (24), comprise eccentric adjusting nut (25) and adjusting rod (26) thereof, adjusting bracket (19), tuningout screw (20), adjusting bracket (19) and adjusting rod (26) are connected and are supported on the casing (6) by spring (18), and adjusting bracket (19) and roller shelves (21) are to collude formula seam location, to be connected as a single entity and to be supported by the little spring (22) of centre by tuningout screw (20); Abrasive band during operate as normal (15) tensioning owing to the support of spring (18); When needing mounting or dismounting abrasive bands (15), rotation eccentric adjusting nut (25) drive adjusting rod (26), adjusting bracket (19), roller shelves (21), passive cylinder (24) together move forward and backward and get final product loose abrasive band (15) with mounting or dismounting, the tuningout in abrasive band (15) then can be regulated adjusting bracket (19) and makes main, passive two cylinder axle heads keep concordant with interval between the roller shelves (21) by rotating tuningout screw (20), to prevent that abrasive band (15) from taking place to be shifted and to come off at the volley.
On described drive roll (13), can also be fixed with dust suction fan blade (12), and be positioned at by the plane seam and dust shield (11) be installed on the casing to form vacuum chamber, and open the dust mouth at Qi Bi, connect dust bag (10), constitute dust exhaust apparatus (5); When motor (2) rotates, drive dust suction fan blade (12), produce air quantity, the sand dust on the abrasive band is sucked vacuum chamber and is expelled to dust bag by the dust mouth reach dust suction, control of dust purpose.
