The contrast prior art, the utility model connects a linear cam with the upper control claw of formed spring with lower control claw, controls the interior receipts of upper control claw and lower control claw by the rotation of linear cam and opens with outer, to reach the purpose of control spring external diameter; The height of linear cam and angle have the relation of linear change, when the linear cam angle changes like this, can make spring outer diameter also produce linear variable quantity thereupon; Thereby can cooperate microcomputer control system, directly import the external diameter of spring, can access the spring of being wanted, operate and adjust easy, directly perceived, boost productivity.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is provided with schematic diagram for the one embodiment of linear cam;

Accompanying drawing 3 is the control flow chart of microcomputer control system to external diameter;

Accompanying drawing 4 is combined in schematic diagram on the pressure spring machine for the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

See shown in the accompanying drawing 1,4 that control structure of outer diameter of pressure spring machine described in the utility model comprises that the front end of the upper control claw 1 of circle distribution and lower control claw 2, two control claws cooperates guide wire circle song, and control spring external diameter thus.The rear end of upper control claw 1 and lower control claw 2 is fixedly connected with respectively slide block 3 and slide block 4, two slide blocks are installed in respectively in the chute of corresponding site on the support.Linear cam 5 drives two slide block slippages by linkage, control claw 1 and lower control claw 2 are received synchronously or outer opening, the height of linear cam 5 and angle have the relation of linear change, and this linear cam 5 connects servomotor by outside journal axle, and servomotor is controlled by microcomputer control system.

Linkage comprises a connecting rod 61 and a lower link 62 on one, and last connecting rod 61 inner ejections connect the slide block 3 of controlling pawl 1, and upward the outer end of connecting rod 61 is pressed on linear cam 5 outer peripheral faces, and middle part of connecting rod 61 is formed with pivot point 611 on this.One end of lower link 62 and 61 interlocks of last connecting rod, the other end is hinged on the support, and the middle part of lower link 62 is inboard by the lug boss 41 on a stage clip 63 ejection slide blocks 4.Form a positive step 31 that protrudes on slide block 3, step 31 upsides prop up the top and go up connecting rod 61 the inners, and step 31 downsides press down the respective end of lower link 62.

Control flow chart shown in Figure 3 during use, is provided with the minimum point that is positioned at linear cam 5 zero point of outside journal axle, by controller function, rotates outside journal axle, and minimum outer diameter (this is the datum mark of external diameter) is set; Other gets a bit, the actual measurement, and input actual outside diameter value is provided with reference to external diameter (this is the reference point of external diameter); Establish datum mark (minimum outer diameter) and reference point (with reference to external diameter), microcomputer control system can be calculated the external diameter working range according to the linear relationship of external diameter variation, the variation of control spring external diameter, and need not to take into account relevant frame for movement.

Shown in Figure 2, be 180 degree if the angle of minimum outer diameter is set, external diameter is 30.00mm; Angle with reference to external diameter is 90 degree, and external diameter is 60.00mm; The external diameter working range will be 30.00mm-90.00mm, be 75.00mm such as external diameter, and outside journal axle will go to 40 degree places.

Upper control claw 1 and 2 interior time receivings of lower control claw, linear cam 5 rotates, and then connecting rod 61 is put 611 rotations around the shaft in the ejection, and upper connecting rod 61 inner lower top steps 31 make slide block 3 slippage down in chute, can drive like this control claw 1 interior receipts; Slide block 3 moves down then and promotes synchronously lower link 62 by step 31, and lower link 62 drives slide block 4 slippages by stage clip 63, thereby realizes synchronously lower control claw 2 interior receipts.

When upper control claw 1 and lower control claw 2 outer opening, linear cam 5 rotates, upper connecting rod 61 is fallen by the height point of linear cam 5, at this moment stage clip 63 pushes connecting rod 62 revolutions, lower control claw 2 is followed outer opening, and lower link 62 upper ends promote step 31 and make slide block 3 slippage up in chute simultaneously, and upper connecting rod 61 is put around the shaft 611 and rotated, upper control claw 1 and outer synchronously of lower control claw 2 realize the external diameter adjustment.

The height of linear cam 5 and angle have the relation of linear change, and connect servomotor by outside journal axle, and servomotor is controlled by microcomputer control system.Like this can be by the parameter request of microcomputer control system according to the outside input, converse the angle that outside journal axle need to rotate, and by driven by servomotor, can realize that linear cam 5 rotation controls control claw 1 and lower control claw 2 interior receipts or outer opening, reach the effect of control spring external diameter.
