Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to FIGS. 1 to 5: the utility model provides a steel pipe screw thread burr sharpening machine, includes lever 2 and support 1, the upper end of 2 middle part coupling supports 1 of lever, the one end of lever 2 is equipped with coping platform 22, and the other end of lever 2 is equipped with first balancing weight 21, be equipped with handle impeller 222 on the coping platform 22, the weight of first balancing weight 21 is 10kg ~40 kg.
In this embodiment, the sharpening machine is installed in one side of rack 7, is equipped with the unanimous conveyer belt 8 of width on the rack 7, has the clearance between conveyer belt 8 and the conveyer belt, places steel pipe 9 on the conveyer belt, carries the steel pipe, and the rack is stretched out to the screw thread at the both ends of steel pipe to the sharpening machine is polished the screw thread burr.
The sharpening machine comprises a support 1 and a lever 2, the middle of the lever is in shaft connection with one side of the upper portion of the support, a connecting position is defined as a fulcrum 11, and two ends of the lever can rotate around the fulcrum.
Install the coping platform in the one end of lever, define this end as the front end, install the balancing weight with this end of lever, define this end as the tail end, the direction of delivery of steel pipe is for passing through the front end to passing through the tail end. The distance from the front end of the lever to the fulcrum is equal to the distance from the tail end of the lever to the fulcrum.
The lever is made of iron materials, a first balancing weight 21 is welded below the tail end of the lever and made of iron materials, the weight of the first balancing weight is preferably 25kg, a polishing platform is installed at the front end of the lever, a handle impeller is installed in the polishing platform, the weight of the handle impeller is almost 10kg, and a hanging block is installed between the front end of the lever and a fulcrum. Therefore, the weight of the first balancing weight is not easy to be lower than 10kg until the weight of the first balancing weight is not easy to be lower than 20kg, and the weight of the first balancing weight cannot be too heavy, so that the phenomenon that when the grinding machine operates, the pressure of the handle impeller to the steel pipe is too large due to the overweight of the first balancing weight, and the thread burrs of the steel pipe are excessively ground. The weight of the first weight block is finally selected to be 25 kg. In addition, the first balancing weight is also provided with a second balancing weight (not shown), the second balancing weight is made of a material with magnetic force, the second balancing weight is a plurality of blocks which are made into cuboids with different weights, and the second balancing weight comprises a plurality of balancing weights with weights of 1kg, 2kg, 3kg, 4kg, 5kg and 10 kg. When the sharpening machine runs, the second balancing weight can be selected as required to be adsorbed on the first balancing weight, so that the pressure of the handle impeller in the sharpening platform to the steel pipe is changed, and burrs on the threads of the steel pipe are better removed.
The support is close to on one side of tail end slant fixed mounting have gag lever post 3, and the gag lever post can be cylindrical, also can be rectangular shape, can weld on support 1, also can bolted connection on the support, and the effect of gag lever post is when the tail end upwarps, fixes the tail end at a certain height, makes the tail end can not exceed the rack to in order to influence the transport of steel pipe.
A hanging block 4 is arranged at the lever between the polishing platform at the front end of the lever and the support, the hanging block 4 is connected to the lever through a steel wire rope, and the weight of the hanging block is 25 kg. Hang the weight of piece and add the weight of coping platform, can make the lever tail end perk that only first balancing weight upwards, hang the weight of piece and be difficult for overweight, because when the lever tail end perk, have the gag lever post to carry on spacingly to it, if hang a weight overweight, can make the effort increase between this section lever of lever tail end and the gag lever post, the time has long can lead to the fact the damage to lever and gag lever post. One side of the support close to the hanging block extends out to form a parking platform 5 of the hanging block, when the hanging block is placed on the parking platform, the steel wire rope is in a contraction state, and the front end of the lever can tilt. A sliding rod 221 is arranged in the grinding platform, a handle impeller is installed on the sliding rod 221 and driven by a set of 24V power-supply small-volume 300W power motor power system, the sliding rod is arranged in the transverse direction of the steel tube, and the handle impeller can move back and forth on the sliding rod, namely the transverse direction of the steel tube. The handle impeller moves back and forth on the slide rod, and the structure of a mechanism of the crank slider can be used for reference.
The middle part of the rack is also provided with a tube detection auxiliary machine which comprises a support frame 6, and the height of the tube detection auxiliary machine is lower than that of the conveying belt when the tube detection auxiliary machine does not work. The upper portion of support frame is installed action wheel 61 and follow driving wheel 62, and action wheel 61 is connected with driving motor (not shown) hub connection, and driving motor drives the action wheel and rotates, and driving motor's model selects VGLD22-25N400L, or other motors that meet the requirements in the market. Leave the clearance between action wheel 61 and the follow driving wheel 62, the width in clearance is less than the steel pipe diameter, leaves recess 64 on the lateral wall that the clearance corresponds for hold the steel pipe, make the steel pipe contact with the lateral wall of support frame here, only action wheel and driven wheel support the steel pipe.
When the steel pipe stops running, the upper part of the support frame 6 can be lifted, the steel pipe is clamped between the driving wheel and the driven wheel, the driving motor is started to drive the driving wheel to rotate, the driven wheel does not actively rotate, and therefore the steel pipe rotates between the driving wheel and the driven wheel. In order to protect the steel pipe in the pivoted in-process, can not arouse the damage because of with the contact of action wheel with follow driving wheel, at the action wheel with follow the skin parcel one deck protective layer of driving wheel, rubber can be chooseed for use to the material of protective layer to avoid the action wheel, follow the direct contact of driving wheel with the steel pipe. The upper part of the support frame is lifted by a hydraulic mechanism 63 which can lift the upper part of the support frame. The mechanism can be referred to CN201493404U specifically, and the description of the mechanism is provided in CN201493404U in the specific embodiment.
The utility model discloses a use method:
a preparation state: and taking down the second balancing weight, lowering the hanging block, lowering one end of the lever grinding platform, and enabling one end of the lever balancing weight not to exceed the plane of the rack due to the existence of the limiting rod, so that normal conveying of the steel pipe is not influenced.
The working state is as follows: the inspection auxiliary machine rises, jack-up steel pipe, and the second balancing weight is added to the lever tail end, and the lever front end perk will hang the piece and place on parking bench, and handle impeller contact screw thread burr through the adjustment to the second balancing weight that adds makes the pressure of handle impeller to the screw surface of steel pipe reach suitable degree. Starting a motor of the auxiliary pipe inspection machine to drive the steel pipe to rotate; the motor of the handle impeller is started to drive the handle impeller to rotate. And starting grinding, moving the handle impeller back and forth until the thread burrs are completely ground, stopping the motor of the handle impeller, stopping the motor of the auxiliary pipe inspection machine, taking down the second balancing weight, and returning to the preparation state.
