Description

Novel tapping machine

Technical field

The utility model relates to a kind of tapping machine, particularly a kind of novel tapping machine with middle pivoted arm structure.

Background technology

Tapping machine is a kind of equipment that is used for machining screw.Existing tapping machine, generally contain parts such as fixed support, workpiece clamping tool, head tree, motor, back belt pulley, V belt, guard shield, preceding belt pulley, front end cantilever, start button, lifting control crank, lifting shaft, tap chuck, screw tap, workpiece clamping tool, head tree are separately fixed on the fixed support, the front end cantilever is fixed on the head tree, motor is fixed on the front end cantilever, forward and backward belt pulley links to each other by V belt, lifting shaft is installed on the front end cantilever, and screw tap is installed on the lifting shaft by tap chuck.Because the front end cantilever is fixed, screw tap can only move up and down, and by adjusting the location of workpiece of desire processing, realizes the processing in same workpiece diverse location hole.Because the individual pieces volume is bigger, thereby it is very inconvenient to adjust workpiece, and efficient is low, and because tapping centering difficulty causes screw tap to fracture often, or the damage workpiece, the material cost height.Concrete manifestation is as follows:

1. the high aspect of cost:

1., owing to cause screw tap to fracture often, cause cutter use cost height;

2., because to big location of workpiece adjustment inconvenience, the damage of workpiece outward appearance is serious, causes workpiece repair rate height, thereby strengthens processing cost, and presentation quality is poor.

2. working (machining) efficiency is hanged down the aspect:

1., because the motion of workpiece relies on manual setting fully, workpiece push-and-pull campaign centering difficulty, and, cause the workpiece working (machining) efficiency not high to all factors such as the overdraw of operating personnel's physical efficiency are big because of workpiece weight is big;

2., because workpiece repair rate height, the tool changing cycle shortens influences working (machining) efficiency equally.

Above reason causes the product cost height, and product market competitiveness is poor.

Summary of the invention

The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of improved tapping machine is provided, and this tapping machine can be implemented in to be desired under the motionless situation of processing work, arbitrarily, the processing work upper surface tapping in hole on a large scale exactly, processing method is simple, and cost is low, the efficient height.

For realizing that the technical scheme that above-mentioned purpose of the present utility model adopts is:, change two rotatable pivoted arms into original single cantilever mounted.The utility model comprises fixed support, the workpiece clamping tool, head tree, motor, back belt pulley, the front end cantilever, preceding belt pulley, start button, the lifting control crank, lifting shaft, tap chuck, screw tap, the workpiece clamping tool, head tree is separately fixed on the fixed support, lifting shaft is installed on the front end cantilever, screw tap is installed on the lifting shaft by tap chuck, its design feature is that two axial thrust bearings are installed on head tree, pivoted arm in the middle of between axial thrust bearing, installing one, one intermediate rotary shaft is installed on middle pivoted arm, the front end cantilever is installed on the intermediate rotary shaft, belt pulley also is equipped with on intermediate rotary shaft top, this belt pulley links to each other with preceding belt pulley and back belt pulley respectively by two V belts, and motor is fixed on the middle pivoted arm.

Because the front end cantilever is installed on the intermediate rotary shaft, therefore the utlity model has two pivoted arms, pivoted arm and front end can easily be adjusted the screw tap position on a large scale by two pivoted arms around the front end cantilever of intermediate rotary shaft rotation promptly, can accurately process workpiece by processing request, improved production efficiency greatly, and because to the light centering of workpiece hole potential energy, thereby product quality significantly improves, and the loss of cutter screw tap simultaneously also significantly reduces thereupon, whole cost obviously descends, and concrete manifestation is as follows:

1. cost hangs down the aspect:

1. operating efficiency improves, and the operating efficiency after the improvement improves 50% than before improving, and reduces administrative expenses greatly;

2. the loss of cutter screw tap significantly reduces, and can improve 25% the service life of the cutter screw tap of the tapping machine after the improvement before improving;

3. defective products is reprocessed quantity and is effectively controlled, and first-time qualification rate is than improving 10% originally.

2. the high aspect of working (machining) efficiency:

1. owing to adopt elder generation that workpiece is carried out fixing fast as required, tapping machine is easily adjusted the screw tap position by pivoted arm, and workpiece is accurately processed, and the operating personnel not power of costing get final product easy manipulation, thereby makes the workpiece working (machining) efficiency improve 50%;

2. be effectively controlled owing to defective products is reprocessed quantity, screw tap is changed number of times and is reduced, and has improved production efficiency indirectly.
