[0003] When installing the volute spring into the lower spring cylinder, the volute spring needs to be in a contracted state, so a contraction force needs to be applied to the spring during installation. This is difficult to accomplish manually, so a device for installing the volute spring into the lower spring cylinder is needed. Summary of the invention

[0004] In order to enable the spiral spring to be smoothly installed in the lower spring cylinder, the present application provides a spiral spring assembly machine for a valve control structure.

[0005] The above technical objectives of this application are achieved through the following technical solutions: A valve control structure spiral spring assembly machine includes a base, an operating panel is arranged on the base, a plurality of slide grooves are opened on the operating panel toward the center of the operating panel, a slider is slidably connected in the slide groove, a fan-shaped clamp is fixedly connected above the slider, a fan-shaped groove is opened on the upper surface of the fan-shaped clamp, and a plurality of fan-shaped clamps can be combined to form a complete circle, the spiral spring is arranged in the fan-shaped groove, a center groove is opened at the center position of the base, a center axis is arranged in the center groove, the center axis can rotate in the center groove, and a clamping groove is opened at the upper end of the center axis, and the center position of the spiral spring is clamped in the clamping groove.

[0006] By adopting the above scheme, when the volute spring needs to be installed in the cylinder, the volute spring is placed in the fan-shaped groove, and the center of the volute spring is clamped in the clamping groove. Then the operator drives the central shaft to rotate, so that the volute spring curls toward the center position. At the same time, the slider slides in the slide groove, driving the fan-shaped clamping blocks to approach each other, thereby compressing the volute spring until the volute spring can be installed in the lower spring cylinder body. Then the lower spring cylinder body is put on the top of the volute spring, and then the fan-shaped clamping block is slowly opened to clamp the volute spring in the lower spring cylinder body, so that the volute spring can be smoothly installed in the lower spring cylinder body.

[0007] Optionally, a transmission cavity is opened in the operating disk, the transmission cavity is connected with the slide groove, a transmission ring is rotatably connected in the transmission cavity, the axis of the transmission ring is the same as the axis of the central axis, a spiral groove is arranged on one side surface of the transmission ring, a convex tooth is arranged on the lower surface of the slider, the convex tooth is meshed with the spiral groove, when the transmission ring rotates, the slider slides along the slide groove, bevel teeth are fixedly arranged on the side of the transmission ring away from the spiral groove, the bevel teeth are meshed with a first bevel gear, the first bevel gear is fixedly connected with a first wheel rod, and the first wheel rod is rotatably connected to the operating disk.

[0008] By adopting the above scheme, the first wheel rod is rotated, and the first wheel rod drives the first bevel gear to rotate, thereby driving the transmission ring to rotate. The transmission ring simultaneously drives multiple sliders to move along the slide groove, thereby driving multiple fan-shaped clamping blocks to approach or move away from each other, thereby achieving the clamping or loosening of the volute spring.

[0009] Optionally, one end of the first wheel rod facing away from the transmission ring is fixedly connected with a hand wheel.

[0010] By adopting the above solution, the operator can more conveniently rotate the first wheel rod, thereby more conveniently installing the spiral spring into the cylinder.

[0012] By adopting the above scheme, the operator can drive the worm wheel to rotate by rotating the worm, thereby driving the drive shaft to rotate, and the drive shaft drives the central shaft to rotate. The worm wheel has a deceleration effect, so that the operator uses less force to rotate the central shaft, and the worm wheel has a self-locking structure to prevent the volute spring from rebounding and driving the central shaft to rotate.

[0013] Optionally, the first wheel rod is fixedly connected to the second bevel gear, the second bevel gear is meshed with the third bevel gear, the third bevel gear is fixedly connected to the second wheel rod, the second wheel rod is fixedly connected to the first spur gear at one end facing away from the third bevel gear, the first spur gear is meshed with the second spur gear, and the second spur gear is fixedly connected to the worm gear.

[0014] By adopting the above scheme, the operator rotates the first wheel rod to drive the second bevel gear to rotate, thereby driving the third bevel gear and the second wheel rod to rotate. The second wheel rod drives the worm to rotate through the first spur gear and the second spur gear. The worm drives the worm wheel and the drive shaft to rotate, thereby driving the center shaft to rotate, so that the operator can operate the arc clamp and the center shaft movement at the same time, so that the volute spring can be smoothly installed in the lower spring cylinder.

[0015] Optionally, an insertion groove is provided at one end of the driving shaft, and an insertion rod is fixedly connected to the end of the central shaft away from the slot, and the insertion rod is inserted into the insertion groove. When the insertion rod is inserted into the insertion groove, the driving shaft and the central shaft can only slide relative to each other.

[0016] By adopting the above solution, the driving rod and the central shaft can be separated, so that the spiral spring can be more conveniently clamped in the clamping groove.

[0017] Optionally, the fan-shaped groove includes a primary groove and a secondary groove, the diameter of the primary groove is larger than the diameter of the secondary groove, and the centers of the primary groove and the secondary groove are the same.

[0018] By adopting the above solution, the assembling machine can assemble spiral springs of different sizes.

[0019] In summary, this application has the following technical effects: 1. By setting up the fan-shaped clamp block and the center shaft, the center position of the volute spring is clamped in the clamping groove. The rotation of the center shaft drives the center of the volute spring to shrink. At the same time, the fan-shaped clamp block shrinks the edge of the volute spring, thereby tightening the volute spring, so that the volute spring can be smoothly installed in the lower spring cylinder; 2. The hand wheel is provided so that the operator can turn the first wheel lever more smoothly, thereby driving the spiral spring to contract more smoothly; 3. The worm wheel and worm are arranged to drive the driving shaft to rotate, thereby driving the central shaft to rotate, and then driving the center of the spiral spring to contract.
