Description

Technical Field

[0001] The utility model relates to a spring clamp ring assembly mechanism for a valve core. Background Art

[0002] In the production of some safety valves, after the valve core is assembled into the valve body, it needs to be fixed in place with a spring retaining ring to prevent the valve core from falling out of the valve body. Currently, the spring retaining ring is manually installed using a ring-retracting insert. The spring retaining ring is narrowed, inserted into the valve body, and then released. Once the spring retaining ring loses the force of the ring-retracting insert, it quickly returns to its original shape and becomes stuck on the inner wall of the valve body, pressing against the valve core. However, manual assembly is significantly slow and has high production costs.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a spring clamp ring assembly mechanism for a valve core, which solves the problem of slow manual assembly and effectively reduces the production cost of the manufacturing enterprise.

[0005] The utility model proposes a spring clamp ring assembly mechanism for a valve core, which includes a vibration disk, a lower pressure head, a material preparation table and a feeding slide. The feeding slide is arranged above the material preparation table and can slide back and forth relative to the feeding slide. A material receiving port is provided on the feeding slide and passes through the material up and down. A material guide track is connected to the vibration disk, and the output end of the material guide track corresponds to the material receiving port. A narrow material channel is provided on the material preparation table and passes through the material up and down. The narrow material channel is in the shape of a trumpet that is wide at the top and narrow at the bottom. The lower pressure head is arranged above the narrow material channel. The feeding slide can slide forward relative to the material preparation table and make the material receiving port correspond to the upper end opening of the narrow material channel.

[0006] In one or more embodiments, the feeding slide is driven to slide by a driving cylinder, and the driving cylinder is arranged at the rear of the feeding slide, and the cylinder shaft of the driving cylinder is connected to the back of the feeding slide.

[0007] In one or more embodiments, the size of the pressure head is consistent with the size of the opening at the bottom end of the narrow material channel.

[0008] In one or more embodiments, the pressing head is driven by a pressing device, which includes a column, a pressing cylinder, a vertical rail and a slide. The slide is slidably connected to the vertical rail, and the pressing head is installed on the slide. The pressing cylinder is fixed to the column and is used to drive the slide to move up and down.

[0009] In one or more embodiments, the slide is provided with a mounting port, the lower pressure head includes a pressure column and a connecting head, the connecting head is fixed to the top of the pressing part, the pressure column is passed through the mounting port, and the slide is provided with a fixing seat for pressing the connecting head.

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] Please see attached Figure 1-3 The utility model provides a spring retaining ring assembly mechanism for a valve core, which includes a vibration disk 1, a pressure head 2, a material preparation table 3 and a feeding slide 4. The feeding slide is arranged above the material preparation table and can slide back and forth relative to the material preparation table. Specifically, the feeding slide 4 is driven to slide by a driving cylinder 8. The driving cylinder is arranged at the rear of the feeding slide, and the cylinder shaft of the driving cylinder is connected to the back of the feeding slide. The feeding slide 4 is provided with a material receiving port 5 that passes through from top to bottom. A material guide rail 6 is connected to the vibration disk. The output end of the material guide rail corresponds to the material receiving port 5, so as to accurately guide the spring retaining ring to the material receiving port. The material preparation table is provided with a narrow material channel 7 that passes through from top to bottom. The narrow material channel is in the shape of a trumpet that is wide at the top and narrow at the bottom. The pressure head 2 is arranged above the narrow material channel. The feeding slide 4 can slide forward relative to the material preparation table and make the material receiving port 5 correspond to the upper end opening of the narrow material channel 7. After the spring clamp falls to the material receiving port, it moves forward through the feeding slide to correspond to the upper opening of the narrow material channel. The spring clamp will fall into the narrow material channel, and then the spring clamp will be gradually pressed down by the pressing head. The spring clamp will gradually narrow in the process of passing through the narrow material channel, achieving the effect of a narrow ring.

[0017] The size of the pressing head 2 is consistent with the opening size of the bottom end of the narrow material channel 7 to ensure that the pressing head can fit the bottom end opening of the narrow material channel and always maintain contact with the spring clamping ring, so that the spring clamping ring is evenly stressed at all positions, which is conducive to improving its narrow ring effect.

[0018] The pressing head 2 is driven by a pressing device, which includes a column 9, a pressing cylinder 10, a vertical rail 11 and a slide 12. The slide is slidably connected to the vertical rail. The pressing head 2 is installed on the slide 12. The pressing cylinder is fixed to the column and is used to drive the slide to move up and down. The slide is driven up and down by the pressing cylinder, and then the pressing cylinder can move up and down. This structure adopts the cooperation of the slide and the vertical rail, which can improve the stability of the pressing head when pressing down.

[0019] The slide 12 is provided with a mounting opening, and the lower pressure head includes a pressure column 21 and a connecting head 22. The connecting head is fixed to the top of the pressure, and the pressure column is passed through the mounting opening. The slide is provided with a fixing seat 13 for pressing the connecting head. The use of this structure can facilitate the production enterprise to replace the lower pressure head of appropriate size according to the spring clamp ring of different ring size. The fixing seat 13 is fixed to the slide 12 by bolts. The use of bolts for fixing has the advantages of easy installation and disassembly, which is convenient for users to disassemble and assemble.
