Abstract
The present invention has and can prevent from along the circumferential direction to rotate and convert reciprocating driving member to by pendular body.Task of the present invention is to make a kind of driving member anti-rotation safety device, and this driving member can move under the impact bar effect that has convex shoulder of pendular body, and it is simple that the structure of this device is wanted, and is easy to assembling and can not throws off insurance.The solution that the present invention makes above-mentioned task is that the convex shoulder (13) that makes impact bar (6) is positioned at two and becomes between the pin (14,15) that determining deviations are arranged in parallel, one end of pin is fixed in the rear wall (16) of driving member (1), and the other end is fixed in the tail wall (17) of driving member rear portion boss.
Description
The present invention relates to a kind of portable percussion drill that has impactor, this percussion drill is equipped with a piston shape driving member that is positioned at cylindrical cylinder, this driving member can order about one and can move reciprocatingly by free-moving vertically impact body under compressed-air actuated effect, impact body passes to the cutter that is installed on the percussion drill with its energy with the form of axial impact, driving member converts rotatablely moving of motor to the runout motion by a pendular body, have a round end impact bar that is disposed radially on the pendular body, the round end of this impact bar is installed in the boss at piston shape driving member rear portion, impact bar radially extends outward a convex shoulder from the round end place, and this convex shoulder can not carry out tangential motion in the boss at drive piston rear portion.
In order to prevent that driving member from rotating, there is the people once to advise the convex shoulder of impact bar is contained in the disk that has slotted hole, disk then is installed on the boss at driving member rear portion (seeing the Germany patent specification No. 3335305).
This safe disk and installation thereof be the cost height on the one hand, can't implement on the other hand, because disk has the danger that comes off in operation, thereby damages driving member.
Task of the present invention is to make a kind of driving member anti-rotation safety device, and it is simple that its structure is wanted, and is easy to assembling, and can prevents to come off.
According to the present invention, the solution of above-mentioned task is as follows, and the convex shoulder that makes impact bar is between two pins that become a determining deviation and be arranged in parallel, and an end of pin is fixed in the rear wall of driving member, and the other end is fixed in the tail wall of driving member rear portion boss.
Contrast description of drawings one embodiment of the present of invention below.Wherein:
Fig. 1 represents driving member and by the partial view of the pendular body of its drive,
Fig. 2 represents the vertical view of driving member,
The cutaway view in A-B cross section in Fig. 3 presentation graphs 2.
As shown in Figure 1, be impact body that the driving member 1 of hollow piston shape can move freely vertically 2 and convert reciprocating motion to, a boss 3 is arranged at the rear portion of driving member, bearing holder (housing, cover) 4(ring is housed in this boss) by air cushion.Spherical round end 5 on the impact bar 6 is positioned at bearing holder (housing, cover) 4, impact bar.Radially extend and be fixed on the outer shroud of a ball bearing 8, the axis of this bearing and jackshaft 10 becomes the α angle of cut, jackshaft has axle sleeve 12 on (10), and the interior ring 11 of the inclination installation of ball bearing 8 is then being overlapped in this axle sleeve outside, and jackshaft (10) drivable shaft cover rotates.
Outstanding convex shoulder 13 on the impact bar round end 5 is positioned at two and becomes between the pin for suppressing metal 14,15 that determining deviations are arranged in parallel, and an end of this pin is fixed in the rear wall 16 of driving member, and the other end is fixed in the tail wall 17 of driving member rear portion boss.
Two pins for suppressing metal 14 and 15 are through in the through hole 18,19 on the tail wall 17 of boss 3 and compress forward, until its stretch into blind hole 18 on the wall of driving member ', 19 ' interior (referring to Fig. 2 and Fig. 3).
Such safeties can prevent the rotation that driving member is along the circumferential direction gone up, and the moment of torsion that acts on the driving member is owing to effect on the direction of rotation of impact bar 6 has the center of component and round end 5 to produce displacement.
Claims (4)
1, the portable percussion drill that has impactor, a piston shape driving member that is positioned at cylindrical guide pipe is housed, this driving member can order about one and can move reciprocatingly by free-moving vertically impact body under compressed-air actuated effect, impact body passes to the cutter that is installed on the percussion drill with its energy with the form of axial impact, driving member converts rotatablely moving of motor to the runout motion by a pendular body, have a round end impact bar that is disposed radially on the pendular body, the round end of this impact bar is installed in the boss at piston shape driving member rear portion, impact bar radially extends outward a convex shoulder from the round end place, this convex shoulder can not carry out tangential motion in the boss at drive piston rear portion, feature of the present invention is that the convex shoulder (13) of impact bar (6) is positioned at two pins (14 that become a determining deviation to be arranged in parallel, 15) between, one end of pin is fixed in the rear wall (16) of driving member (1), and the other end is fixed in the tail wall (17) of driving member rear portion boss.
2, percussion drill according to claim 1 is characterized in that safety pin is a closing sleeve.
3, percussion drill according to claim 1 is characterized in that safety pin is a straight pin.
4, one of require described percussion drill according to aforesaid right, it is characterized in that safety pin (14,15) is directly installed on and be positioned at driving member rear portion boss, be used to lay the end face of bearing holder (housing, cover) (4) of the round end (5) of impact bar (6).
