Abstract
The invention relates to a handheld type combined motion hole grinding head. One end of a shell is fixedly mounted on a motor through a fastening bolt. In a mounting process, the motor and an axis of the shell are kept on a same axis plane; a grooved cam path is formed on an external circle of a cam along circumference direction; the cam is mounted in the shell through a transmission shaft; one end of the transmission shaft is mounted together with the left end of the shell through a sliding shaft bearing; an inner spline is arranged at the right end of the transmission shaft; the transmission shaft is matched with a spline shaft through the inner spline; the transmission shaft and the spline shaft are matched with each other, with a degree of freedom for axial sliding but without degree of freedom for circumferential rotating; one end of a positioning pin is fixedly mounted on the shell; and the other end of the positioning pin is embedded in the groove-shaped cam slot.
Description
Technical field
The present invention relates to a kind of compound motion hole grinding head, particularly a kind of hand-held compound motion hole grinding head belongs to hardware ﹠ tools and machining equipment technical field.
Background technology
In machine-building, flight-line maintenance field; run into the processes of existing hole being ground or carrying out other through regular meeting; at present, the main tool of carrying out this type of processing is drilling machine or special bistrique, the working method of this two classes instrument; a kind of working method of having only rotation; when needs are done the work of certain stroke, need corresponding mechanism, not only cost is higher; use inconvenience, especially incompatible in place of moving and the use in the maintenance work.
Summary of the invention
The objective of the invention is to: provide a kind of simple in structure, have hand-held compound motion hole grinding head, adapt in the open air or the use in other maintenance place.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of hand-held compound motion hole grinding head, it is made up of motor, cam, alignment pin, sliding bearing, housing, bistrique, fastening bolt, power transmission shaft, splined shaft.Described housing is the structure of a hollow cylindrical, one end installs and fixes together by fastening bolt and motor, simultaneously, the axis of motor and housing is in above the same axis, described cam is a columned structure, produce the cam path of grooved above the circumferencial direction on the cam circle cylindrical, described cam is installed in enclosure interior by power transmission shaft, described power transmission shaft one end is installed together by the left end of sliding bearing and housing, the right-hand member manufacturing of the axle that passes has internal spline, and be combined together by internal spline and splined shaft, described alignment pin one end is fixed on above the housing, an other end of alignment pin is embedded in the cam path of cam grooved, and the main shaft of described splined shaft and motor is connected as a single entity.
Operation principle of the present invention is: when motor rotates, motor drives the power transmission shaft rotation by splined shaft, power transmission shaft drives cam rotation mounted thereto again, because the cylindrical epirelief race of cam, the bearing pin and the housing that are embedded in the cam path are fixed together, so, just one side rotation of cam, one side moves back and forth along axis direction, and is same, be installed in the also just rotation on one side of bistrique above the power transmission shaft, move back and forth on one side.
Beneficial effect: the present invention is owing to have rotation and move back and forth performance, so the present invention is not only simple in structure, simultaneously, has easy to usely, can adapt to the use of multiple occasion.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is the annexation figure between power transmission shaft, the splined shaft;
Described in the figure: 1, motor; 2, cam; 3, alignment pin; 4, sliding bearing; 5, housing; 6, bistrique; 7, fastening bolt; 8, power transmission shaft; 9, splined shaft.
The specific embodiment
Housing (5) one ends are installed and fixed together by fastening bolt (7) and motor (1), when mounted, guarantee that the motor (1) and the axis of housing (5) are in above the same axis, on the circumferencial direction of cam (2) above the cylindrical, produce the cam path of grooved, cam (2) is installed in the inside of housing (5) by power transmission shaft (8), one end of power transmission shaft (8) is installed together by the left end of sliding bearing (4) with housing (5), right-hand member manufacturing at power transmission shaft (8) has internal spline, power transmission shaft (8) is combined together by internal spline and splined shaft (9), power transmission shaft (8) has the free degree in axial sliding with splined shaft (9) on cooperating, there is not the free degree of circumferentially rotating, alignment pin (3) one ends are fixed on above the housing (5), and an other end of alignment pin (3) is embedded in the cam path of cam (2) grooved.
Claims (2)
1. hand-held compound motion hole grinding head, it is made up of motor (1), cam (2), alignment pin (3), sliding bearing (4), housing (5), bistrique (6), fastening bolt (7), power transmission shaft (8), splined shaft (9), it is characterized in that: produce the cam path of grooved above the circumferencial direction of described cam (2) above the cylindrical, cam (2) is installed in the inside of housing (5) by power transmission shaft (8).
2. according to claims 1 described a kind of hand-held compound motion hole grinding head, it is characterized in that: alignment pin (3) one ends are fixed on above the housing (5), and an other end of alignment pin (3) is embedded in the cam path of cam (2) grooved.
