Abstract

The utility model relates to a facility for processing welding rod in particular to a grinding head machine for grinding the holding end of the manually welding rod. The utility model is provided for solving the problems that the existing grinding head machines comprise a large amount of components in the elevating mechanisms, when the grinding head machines elevate and descend, the platforms are easily clamped and the screw rods are easily broken and the grinding head machines need much maintenance. The utility model has the advantages of inconvenient operation and high efficiency. The utility model integrates the upright post and the screw rod and uses two sets of upward and downward rotations to adjust the distance between the two platforms to realize the elevating control between the upper and the lower steel wire wheels. Furthermore, the utility model replaces the worm wheel rod driving speed reducing mechanism of the existing equipment with a vertical type planet cycloid speed reducer.

Description

Head-grinding machine

The utility model relates to the welding rod process equipment, the bistrique machine of the manual welding rod bare terminal end of particularly a kind of grinding.

Existing bistrique machine mainly is made up of motor, platform, column, wire wheel, thread rolling wheel, thread rolling case and decelerator, and the lifting of milled portion two wire wheel positions is positions of adorning in column between two cover minor leading screws, nut and fixture realization adjusting two platforms.This structure is because of the stressed symmetry that is difficult to, and the jammed phenomenon of platform takes place in regular meeting in lifting control.Plate movable wire bar firmly, and often make the screw mandrel fracture.Because parts are many, fixing operation operation trouble is used inconvenience, and, fixture needs frequent oily maintenance again, in addition, the main transmission section of bistrique machine--be in transmission connection by worm speed-down between following thread rolling case and the motor, transmission efficiency is poor, and the worm gear wearing and tearing are severe, and the maintenance transposing is frequent.

The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art part, and bistrique machine a kind of simple in structure, easy for operation is provided.

The technical solution of the utility model is such: a kind of bistrique machine comprises motor, column screw mandrel, platform, spinning roller, feeding planker, wire wheel, thread rolling case, thread rolling wheel and decelerator.The column screw mandrel is positioned at the tail end of feeding planker, and the two is 90 ° of right angles and connects, and two groups of upper and lower spinning rollers are arranged on the column screw mandrel, and the Luo line is connected between last spinning roller, time spinning roller and column screw mandrel.Two platforms are enclosed within on the column screw mandrel, and lay respectively between two groups of upper and lower spinning rollers.One end of two platforms is rigidly connected with the axle bed of two wire wheels separately, and the link position symmetry.

The utility model proposes of task is also finished by following technical proposals: as being in transmission connection by the vertical-type planetary cycloidal reducer between the following thread rolling case of bistrique machine main transmission section and the motor.

Compared with prior art, the utility model unites two into one column, screw mandrel, has both made elevating screw usefulness, makes centering usefulness again, annexs the upper and lower spinning roller group of the usefulness of lifting and locking in addition, can make things convenient for and adjust two platforms leggiero.Because the support face was big when spinning roller rotated, platform can jammed problem when having solved lifting.Vertical-type planetary cycloidal reducer set between following thread rolling case and the motor has replaced original turbine and worm decelerator, has improved transmission efficiency, has reduced the maintenance amount.The utility model simple structure, lifting is light, and locking is stable, the renewal product of the welding rod process equipment of can yet be regarded as.

Accompanying drawing is a partial structurtes schematic diagram of the present utility model.

Below, embodiment in conjunction with the accompanying drawings is further described the utility model.

The elevating mechanism of bistrique machine is by circular abutment screw mandrel 2,11, two groups of upper and lower spinning rollers 3 of upper and lower two platforms and 12 and feeding planker 10 form, column screw mandrel 2 is positioned at the tail end of feeding planker 10, the two is 90 ° of connections.Two groups of upper and

lower spinning rollers

3 and 12 are enclosed within on the column screw mandrel 2 successively, and spinning roller is connected with the column screw mandrel Luo of portion line, and two hoistable platforms 11 are enclosed within on the column screw mandrel 2, lay respectively between two groups of upper and lower spinning rollers 3 and 12.One end of two platforms is rigidly connected with the axle block of the wire wheel 4 of two upper and lower settings respectively.Two wire wheels 4, each free two motor 1 driven rotary, and switched in opposite are equipped with vertical-type planetary cycloidal reducer 8 between the following thread rolling case 9 and electric 1 as the main transmission section of bistrique machine.

During the work of bistrique machine, the speed of the delivery wheel of following thread rolling case 9---following thread rolling wheel 7 is slower than thread rolling wheel 5, so, welding rod 6 turn to identical on thread rolling wheel 5 and following thread rolling take turns between the upper and lower wire wheel 4 that is rolled into forward under 7 the effect in the high speed rotating, under the grinding of two wire wheels 4, the medicinal powder of welding rod bare terminal end is removed, bare terminal end is by brighten, if will adjust the distance between the upper and lower wire wheel 4, unclamp earlier spinning roller 3 on two respectively, adjust twice spinning rollers 12 then respectively and make two platforms 11, use spinning roller 3 lockings at last to required separately height.The grinding length of welding rod bare terminal end is adjusted by feeding planker 10.

Claims

1, a kind of bistrique machine comprises motor, column screw mandrel, platform, spinning roller, feeding planker, wire wheel thread rolling case, thread rolling wheel and decelerator, it is characterized in that:
