Abstract
The utility model provides a rocking arm locking device of a rocking arm drilling machine, which relates to screw rods and screw nuts which are connected between both sides of a rocking arm locking butt-joint port. Two sets of screw rod and screw nut locking devices are arranged at the rocking arm locking butt-joint port, a screw rod linking and rotating device composed of a crank and a connecting bar is arranged between the two sets of screw rod and screw nut locking devices, and the end of one of the screw rods is connected with a locking handle. The utility model is used for locking or loosening a rocking arm, the two sets of screw rod and screw nut locking devices can be synchronously operated by moving the locking handle so that bolts do not need to be respectively screwed by a spanner, and the utility model has simple and reliable operation.
Description
Technical field:
The utility model relates to the device of on the radial drilling machine rocking arm being locked.
Background technology:
General rocking arm locking device adds that by two bolts two nuts realize.Though this structure is simple, also will twist bolt with spanner again in practical operation, make rocking arm lock or unclamp, it is cumbersome to operate.
Summary of the invention:
The purpose of this utility model provides a kind of radial drilling machine rocking arm locking device, makes rocking arm locking or simple to operate when unclamping.
The purpose of this utility model realizes as follows: this radial drilling machine rocking arm locking device, relate to the leading screw and the screw that are connected between the rocking arm locking docking port both sides, the place arranges two leading screws, screw retaining mechanism at rocking arm locking docking port, between two cover leading screws, the screw retaining mechanism leading screw interlock whirligig is housed, the end of a leading screw connects set lever therein.Locking or when unclamping rocking arm, move set lever with hand, drive the relative screw rotation of this leading screw, drive another leading screw and rotate synchronously by being connected leading screw interlock whirligig between two cover leading screws, the screw retaining mechanisms simultaneously, relative leading screw precession of screw or back-out, make rocking arm locking docking port both sides further or decontrol, thus locking or unclamp rocking arm.
Leading screw interlock whirligig is a fixed crank on each leading screw, connects connecting rod between two cranks.
This radial drilling machine rocking arm locking device when rocking arm is locked or unclamped, is moved set lever and just can be made two cover leading screw screw retaining mechanism synchronization actions, does not need to twist respectively bolt with spanner again, and operation is simple and reliable.
Description of drawings:
Accompanying drawing is the structural representation of the utility model radial drilling machine rocking arm locking device.
The specific embodiment:
With reference to accompanying drawing, 1 locking docking port place arranges two leading screws 6 or 8 at rocking arm, screw 4 retaining mechanisms, the every pair of leading screw 6 or 8, the frame mode of screw 4 is: on rocking arm 1 locking docking port dual-side concentric shoulder hole is arranged, in shoulder hole on one side, screw 4 is housed, shoulder hole Inner Front End at another side is equipped with spacer sleeve 9 and thrust ball bearing 10, leading screw 6,8 pass spacer sleeve 9 and thrust ball bearing 10, and pass gap between the rocking arm locking docking port dual-side, leading screw 6,8 front ends revolve knot together with corresponding screw 4 by screw thread, leading screw 6, the boss of 8 rear ends is pressed on the thrust ball bearing 10, at each leading screw 6, being in rocking arm 1 on 8 locks on the position in gap between the docking port dual-side by flat key 7 circumferential fixed cranks 2, between two cranks, 2 tops, pass through straight pin 3 hinge connective poles 5, the end of a leading screw 6 connects set lever 12 by taper bolt 13 therein, and the top of set lever 12 is by engage thread fixed handle ball 11.During operation, move set lever 12 and drive leading screws 6 rotations, make leading screw 6 precessions or back-out,, drive another leading screw 8 rotations by another crank 2 again, make this leading screw 8 synchronous precession or back-outs, thereby make rocking arm lock or unclamp simultaneously by crank 2 drivening rods 5.When the coupling mechanism force of two cover leading screws 6 or 8, screw 4 retaining mechanisms was not enough or unbalanced, rotation nut 4 was regulated.
Claims (2)
1, a kind of radial drilling machine rocking arm locking device, relate to the leading screw and the screw that are connected between the rocking arm locking docking port both sides, it is characterized in that: the place arranges two cover leading screws (6,8), screw (4) retaining mechanism at rocking arm (1) locking docking port, between two cover leading screws (6,8), screw (4) retaining mechanism leading screw interlock whirligig is housed, the end of a leading screw connects set lever (12) therein.
