[0037] Example 1:

[0038] Please refer to Figure 1 and Figure 2 , which is a first embodiment of the utility model, a drive mechanism 100 for a spring machine, comprising a support plate 10, a power element 20, a cam 30, and an adjustment seat 40. The power element 20 is mounted on the support plate 10 and is used to drive the cam 30 to rotate. The adjustment seat 40 abuts against the cam 30 and slides back and forth on the support plate 10 as the cam 30 rotates. The drive mechanism 100 for a spring machine directly drives the cam 30 through the power element 20, and the adjustment seat 40 abuts against the cam 30. The adjustment seat 40 slides back and forth on the support plate 10 as the cam 30 rotates, thereby achieving expansion and contraction and improving stability. The drive mechanism 100 for a spring machine has a compact structure, precise positioning, and improves the stability of the spring size, making it suitable for producing small-sized springs.

[0039] like Figure 1As shown, in this embodiment, the support plate 10 includes a plate body 11, a guide rail 12, and a slider 13. The guide rail 12 is mounted on the plate body 11, the slider 13 is slidably mounted on the guide rail 12, and the external mechanism is mounted on one end of the slider 13. The power element 20 is mounted on the support plate 10, and the power element 20 is used to drive the cam 30 to rotate; the adjustment seat 40 abuts the cam 30, and the adjustment seat 40 slides back and forth on the support plate 10 as the cam 30 rotates. Optionally, the power element 20 is mounted on the end of the plate body 11 away from the guide rail 12; further, the power element 20 is a motor; in one embodiment, the power output end of the power element 20 is connected to the power input end of the reduction gearbox, and the power output end of the reduction gearbox is fixedly connected to the cam 30 after passing through the plate body 11; the adjustment seat 40 is mounted on the slider 13 to drive the slider 13 to slide.

[0040] like Figure 1 and Figure 2 As shown, the cam 30 includes a first rotating wheel 31 and a second rotating wheel 32 connected to the first rotating wheel 31. The first rotating wheel 31 and the second rotating wheel 32 are both used to abut the adjustment seat 40. The power element 20 is used to drive the first rotating wheel 31 and the second rotating wheel 32 to rotate synchronously. The adjustment seat 40 slides back and forth on the support plate 10 as the first rotating wheel 31 and the second rotating wheel 32 rotate synchronously. Optionally, the second rotating wheel 32 is installed in the first rotating wheel 31; further, a sliding groove 310 is provided between the second rotating wheel 32 and the first rotating wheel 31 to accommodate one end of the adjustment seat 40; further, the outline of the sliding groove 310 corresponds to the shape of the second rotating wheel 32; in one embodiment, the second rotating wheel 32 includes a protruding portion 321 and a retracting portion 322 connecting the protruding portion 321, optionally, the protruding portion 321 is arc-shaped, and the retracting portion 322 is linear, when one end of the adjustment seat 40 abuts the protruding portion 321, the adjustment seat 40 is in an extended state, and when one end of the adjustment seat 40 abuts the retracting portion 322, the adjustment seat 40 is in a retracted state; the retracting portion 322 is arranged in a linear shape to achieve rapid retraction; in other embodiments, the shape of the second rotating wheel 32 is an ellipse or the like.

One end of the elastic member 60a is mounted on the fixed seat 70a, and the other end is mounted on the slide 80a. Optionally, the adjustment seat 40a and the slide 80a are fixed by fasteners.

[0045] Example 3:

[0046] See also Figure 4 and Figure 5, which is a driving mechanism 100b for a spring machine according to a third embodiment of the present invention. This embodiment is similar to the driving mechanism 100 for a spring machine according to the first embodiment, except that the second rotating wheel 32b of this embodiment is mounted on the first rotating wheel 31b, and one end of the adjusting seat 40b abuts the first rotating wheel 31b, and the other end abuts the second rotating wheel 32b. Optionally, a groove 310b is provided on the circumference of the first rotating wheel 31b, and a protrusion 321b is provided on the circumference of the second rotating wheel 32b. When one end of the adjusting seat 40b is accommodated in the groove 310b, the other end abuts the protrusion 321b. At this time, the adjusting seat 40b is in an extended state; further, the first rotating wheel 31b includes a connecting portion 311b, a descending portion 312b and an ascending portion 313b, one end of the descending portion 312b is connected to the connecting portion 311b, and the other end is connected to the ascending portion 313b, and the end of the ascending portion 313b away from the descending portion 312b is connected to the connecting portion 311b, and the descending portion 312b and the ascending portion 313b form a groove 310b; specifically, the connecting portion 311b is arc-shaped, and the descending portion 312b and the ascending portion 313b are inclined surfaces. The second rotating wheel 32b also includes a transition portion 322b, a protruding portion 323b and a retracted portion 324b, wherein the two ends of the transition portion 322b are respectively connected to the protruding portion 323b and the retracted portion 324b, the end of the protruding portion 323b away from the transition portion 322b is connected to one end of the protruding portion 321b, and the end of the retracted portion 324b away from the transition portion 322b is connected to one end of the protruding portion 321b; in one embodiment, the transition portion 322b is an arc shape corresponding to the connecting portion 311b, the protruding portion 323b is an inclined surface corresponding to the descending portion 312b, the retracted portion 324b is an inclined surface corresponding to the ascending portion 313b, and the shape of the protruding portion 321b corresponds to the shape of the connection between the descending portion 312b and the ascending portion 313b.

[0047] Please check again Figure 4 and Figure 5The driving mechanism 100b for the spring machine further includes a first contact wheel 50b and a second contact wheel 60b.

The first contact wheel 50b abuts the first rotating wheel 31b, and the second contact wheel 60b abuts the second rotating wheel 32b. When one end of the first contact wheel 50b is accommodated in the groove 310b, the second contact wheel 60b abuts the protrusion portion 321b. In one embodiment, when the second contact wheel 60b slides along the transition portion 322b, the first contact wheel 50b slides along the connecting portion 311b. At this time, the adjustment seat 40b does not slide and is in a stationary state; when the second contact wheel 60b slides along the protruding portion 323b, the first contact wheel 50b slides along the descending portion 312b. At this time, the adjustment seat 40b is in an extended state until the second contact wheel 60b slides along the protruding portion 321b, and the first contact wheel 50b slides along the connection between the rising portion 313b and the descending portion 312b. At this time, the adjustment seat 40b is in the longest extension stroke; when the second contact wheel 60b slides along the retraction portion 324b, the first contact wheel 50b slides along the rising portion 313b. At this time, the adjustment seat 40b is in a retracted state.

[0048] When in use, the power element drives the first rotating wheel 31b and the second rotating wheel 32b to rotate synchronously. Since one side of the first contact wheel 50b abuts the outer side of the first rotating wheel 31b, and one side of the second contact wheel 60b abuts the outer side of the second rotating wheel 32b, the first contact wheel 50b rotates around the first rotating wheel 31b, and the second contact wheel 60b rotates around the second rotating wheel 32b, thereby driving the adjustment seat 40b and the slider to slide back and forth along the guide rail, realizing extension and retraction and improving stability.
