The device structure is simple and reliable, and the overload protection adjustment is easy, which is convenient for processing with good performance.
Description
Technical field:
The utility model relates to the overload protection arrangement in the radial drilling machine feeding process.
Background technology:
Feeding overload protection arrangement in the past is to bore several screwed holes on the part cylindrical, mounting spring and steel ball in the screwed hole, and the outside is fixed with iron wire after mixing up with the adjustment of fluting awl end holding screw again.Though this structure can reach the purpose of overload protection, to adjust spring pressure and will adjust respectively, difficulty is adjusted in whether even bad grasp of pressure.
Summary of the invention:
The purpose of this utility model provides a kind of radial drilling machine feeding overload protection arrangement, and the overload protection adjustment is easy, and is reliable and stable.
The purpose of this utility model realizes as follows: relate to the feed worm axle and the feeding power axle that are supported on the drilling head casing, feed worm axle and feeding power axle coaxial arrangement, the clutch gear that internal tooth is arranged at a top is fixed in feed worm axle upper end, feeding power axle lower end by bearings on the clutch gear endoporus, the fixing clutch seat down in feeding power axle bottom, being in down on the feeding power axle, the top of clutch seat is with and can moves axially, the circumferential last clutch seat that rotates, last clutch seat bottom be can with the external gear of clutch gear internal tooth engagement, but feeding power axle top is fixed with the spring base of up-down adjustment position; Be with the upper end on the feeding power axle and be supported on the spring base, the lower end is supported on stage clip on the clutch seat by axial thrust bearing; On following clutch seat and the last clutch seat opposite face to some moving teeth should be arranged, the moving tooth tooth top is inserted in the other side's the teeth groove, the moving tooth tooth top with at the bottom of the tooth between be connected at the bottom of transition inclined-plane and the tooth between be placed with steel ball in the cavity that forms, following clutch seat, last clutch seat and steel ball constitute clutch, and the interior outside of a circle steel ball has inner spacing collar and outer separator respectively.During feeding, under the rated load effect, feeding power is transferred to the feeding power axle, the following clutch seat of fixedlying connected with the feeding power axle drives by the steel ball effect and goes up the rotation of clutch seat, last clutch seat makes the feed worm axle follow rotation by the gear rotation that the gear teeth drive on the feed worm axle, and the feed worm axle drives feed mechanism and realizes the feeding purpose.When load was excessive, steel ball rolled between moving tooth inclined-plane, both sides, moves on the clutch seat in the promotion, make the gear teeth and the gear on the feed worm axle of clutch seat break away from engagement, power stops feed motion no longer to feed worm through-drive, has avoided part of damage; Load return to the setting value in the time, last clutch seat moves down under the spring force effect, its tooth portion again with gears engaged, realize normal power transmission.
External screw thread is arranged at feeding power axle top, and the spring base endoporus has internal thread, and spring base is spun on the feeding power axle by engage thread, and the spring base upper side has the locking slot of vertical axial, and the locking slot both sides connect lock-screw.Adjust the position of spring base on the feeding power axle, can adjust initial tension of spring, thereby adjust overload power setting value, the position screws the screw that is connected the locking slot both sides after setting up, and spring base is locked on the feeding power axle, avoids the position to change.
This radial drilling machine feeding overload protection arrangement is simple and reliable for structure, and the overload protection adjustment is easy, convenient processing, and serviceability is good.
Description of drawings:
Fig. 1 is the front view of the utility model radial drilling machine feeding overload protection arrangement.
Fig. 2 is the partial view of overload clutch part among Fig. 1.
Fig. 3 is the expanded view that goes up clutch seat, following clutch seat and steel ball embedded structure.
