Abstract
The invention provides a stepless indexing mechanism in spline cold striking forming equipment, and belongs to the field of indexing mechanisms in mechanical equipment. According to the stepless indexing mechanism, an indexing mechanism in existing spline cold striking equipment is improved. The stepless indexing mechanism is characterized in that the tail end of a workpiece shaft is connected with a step motor, a control panel is connected with the step motor, and a force sensor is installed on a roller main shaft and connected with the step motor. The stepless indexing mechanism has the advantages that the structure of the mechanism is greatly simplified, and precision and efficiency of indexing are improved.
Description
Technical field
The invention belongs to the indexing mechanism technical field, be specifically related to the stepless indexing mechanism in the cold knock shape of a kind of spline equipment.
Technical background
Spline class part is typical transmission, the load bearing element of equipment manufacture and industrial circle, along with developing rapidly of Chinese national economy, the demand of spline class part is increased day by day.The spline class part that traditional cutting machines is produced is because the limit mechanical performance of shaping principle own can not satisfy the demand of existing market.Cut staple, intensity height, surface quality are not good to have the incomparable advantage of traditional cutting technology such as product based on the product of the cold knock shape of the spline of cold forming process device fabrication, economical with materials, and forming efficiency height, cost are low etc.
The cold equipment that strikes of spline that uses both at home and abroad comprises that as shown in Figure 1 indexing mechanism driving-chain I and slide move the driving-chain II at present, slide driving-chain II is to drive slides by gear train 15 and leading screw 16 and workpiece 13 moves axially by motor 14, indexing mechanism driving-chain I then is to drive first, second, third, fourth gear train 3,4,5,6 by main motor 1 by belt transmission 2 to rotate, and drives dial 7 and finger 8 and index dial 9 rotations again.The shortcoming of this cover driving-chain is the various complexity of structure, the indexing mechanism installation accuracy is difficult for guaranteeing that finger and brake apparatus can be subjected to big impact at work, influence the life-span of indexing mechanism, the workpiece number of teeth of processing does not also need to change index dial simultaneously, and calibration efficient is also lower.
The object of the invention provides a kind of cold indexing mechanism that strikes in the equipment of spline of new construction, can overcome the shortcoming that prior art exists effectively.
The present invention realizes like this, be that the cold indexing mechanism driving-chain I of striking in the equipment of existing spline is as shown in Figure 1 transformed, its architectural feature is as shown in Figure 2, the end that is workpiece spindle 10 is connected with stepper motor 18, control panel 17 is connected with stepper motor 18, at the roll main shaft 12 that shapes force-sensing sensor 19 is installed, force-sensing sensor 19 is connected with stepper motor 18 simultaneously.
Advantage of the present invention is that workpiece spindle 10 directly is connected with stepper motor 18, carries out calibration by force-sensing sensor 19 and control panel 17 control step motors 18 this device structure is greatly simplified, and improved indexing accuracy and production efficiency.

Among the figure: 1-main motor; 2-belt transmission; 3-the first gear train; 4-the second gear train; 5-the three gear train; 6-the four gear train; 7-dial; 8-finger; 9-index dial; 10-workpiece spindle; 11-anchor clamps; 12-roll main shaft; 13-workpiece; 14-motor; 15-gear train; 16-leading screw; 17-control panel; 18-stepper motor; 19-force-sensing sensor.
Specific embodiments
Be that 36 workpiece is example with the processing spline tooth number, tempering and taking turns the used time that rotates a circle is T, it is t that the wheel of tempering impacts the time with workpiece at every turn, T-t is the idle period of wheel in a week of tempering, be that T determines the time t that workpiece rotates at every turn with these two parameters of t cold striking after equipment dog parameter and processing work parameter are determined
1, establish T=36 second, t=1 second, T-t=35 second.
According to the shaping principle require cold temper wheel and the workpiece that strikes equipment of spline once impact finish after, workpiece begins intermittently rotation, turn over the number of degrees is 10 ° at every turn, as long as the time t of the each rotation of workpiece
1＜35 seconds, can meet the demands.According to the step angle of above data and selected stepper motor, the adjusting by control panel guarantees that the angle that workpiece turns at every turn is 10 °, the time t of each rotation
1＜35 seconds.When temper wheel and workpiece once impact finish after, the force-sensing sensor 19 of roll main shaft portion passes to stepper motor 18 with signal, stepper motor 18 receives signal and drives workpiece 13 and rotate 10 °, stops then, receives signal up to next time.Realize the rotation at intermittence of workpiece with this.
Claims (1)
