Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Such as Figure 1-Figure 4 As shown, the shaft of the servo motor 1 is fixedly connected to the tail of the ball screw 2, and the ball screw 2 can rotate forward or reverse, or rotate fast or slowly, driven by the shaft of the servo motor 1 .
[0019] The ball screw 2 and the nut slider 4 are clearance fit, the ball screw 2 can rotate in the nut slider 4, and the nut slider 4 can move on the ball screw 2. When the ball screw 2 rotates, it promotes the nut slider 4 to move back and forth.
[0020] The screw nut slide block 4 is clearance fit with the variable diameter base 3, and the screw nut slide block 4 can move forward and backward on the variable diameter base 3; it is a clearance fit with the variable diameter base pressing plate 6, and relative sliding can be arranged. The variable diameter base plate 6 is used to control the s...

The invention relates to a diameter changing mechanism of a numerical control pressure spring machine, which comprises a servo motor, a ball screw rod, a diameter changing base, diameter changing base fixing screws, a nut slide block, a fixed support seat, a diameter changing base press plate, a knife rest, a spring pushing pin, a spring pushing pin seat, a front wall plate and front wall plate arc grooves. The invention simplifies the mechanical control by reinforcing the control of computer software and discards the traditional mechanical approaches of complicated gears, screw rods, cams, and the like; the servo motor controlled by a computer is directly installed on the front wall plate, and a rotating shaft of the servo motor drives the slide block by the ball screw rod with high precision; the slide block drives the spring pushing pin fixed on the slide block to move back and forth and push or depart from a spring steel wire so as to carry out a diameter-changing working procedure for manufacturing the spring. The two arc grooves are arranged on the front wall plate of the pressure spring machine and can contain the diameter changing base fixing screws to slide or lock in thearc grooves, thereby adjusting the function direction of the spring pushing pin on the spring. The upper part and the lower part of the front wall plate are respectively provided with a set of diameter changing mechanisms, and one of the diameter changing mechanisms is selected to carry out operation according to the manufacture requirement of the left rotation or the right rotation of the spring, thereby controlling the outer diameter of the spring.
Description
technical field [0001] The invention relates to a component on a numerically controlled spring machine, in particular to a variable diameter mechanism of a numerically controlled compression spring machine. Background technique [0002] At present, the variable diameter mechanism of the digitally controlled compression spring machine of the prior art is nothing more than relying on mechanical means such as gear transmission, lever transmission, cam transmission, manual adjustment to control the outer diameter of the produced spring. This kind of mechanism not only has complex structure, high noise, many transmission links, and large cumulative error of transmission, but also cannot give full play to the digital control function of the computer, affects the product precision, and has high manufacturing cost. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, break through the traditional habit...
