Technical Field

[0001] This invention relates to the field of valve stem processing equipment technology, specifically to a valve stem size adaptive processing device. Background Technology

[0002] In the valve stem manufacturing process, the valve stem, as the core transmission component of the valve, needs to vary in size and specifications depending on the valve model and application scenario, covering different key parameters such as diameter and length. Currently, in the industry's valve stem processing flow, the pre-processing steps such as loading, guiding, and stacking mostly rely on traditional processing equipment or manual assistance, which presents many technical pain points.

[0003] 1. Poor size adaptability: The guide rails, limiting structures, and feeding mechanisms of existing processing equipment are mostly designed with fixed specifications, which can only adapt to valve stems of a single size;

[0004] 2. Low level of automation: Most equipment lacks an integrated guiding, feeding, and stacking linkage structure, requiring manual placement of valve stems at the processing station or manual assistance to complete the stacking and organization of materials;

[0005] 3. Complex adjustment operation: Adapting and adjusting valve stems of different sizes often requires professional technicians to complete step-by-step debugging of multiple parts with the help of tools. The adjustment is difficult and the error tolerance is low, which makes it difficult to meet the flexible production needs of small and medium batches of valve stems with multiple specifications, thus limiting the company's production flexibility and market response speed.

[0017] The present invention proposes a valve stem size adaptive machining device, the advantages of which are as follows:

[0018] 1. The first electric slide rail adjusts the left and right position of the pushing unit, which, in conjunction with the first hydraulic cylinder, drives the conveying roller to rise and fall, allowing for precise fitting of valve stems of different diameters. The second electric slide rail adjusts the front and rear position of one of the pushing units. The moving baffle of the stacking structure slides in the moving groove via the second bolt, flexibly adjusting the distance between it and the fixed baffle to limit and stack valve stems of different lengths without the need to replace special parts. The stacking plate adjusts its tilt angle via the main body of the third hydraulic cylinder, allowing for orderly convergence of the stems regardless of their size, thanks to their own gravity. The tapered driven roller of the conveying unit, in conjunction with the V-shaped conveying seat, automatically aligns stems of different diameters, ensuring conveying stability.

[0019] 2. The process forms a closed-loop automated flow, from rod stacking (automatic convergence of the stacking structure), single rod feeding (lifting and separating by the push unit), guiding (guided by the guide unit), and conveying (driven by the conveying unit), eliminating the need for manual placement, separation, or pushing of each rod individually. The trapezoidal push plate (inclined wall design) of the push unit, combined with a spring buffer structure, ensures that only a single rod is lifted out of the stacking area during lifting, avoiding the jamming problem when feeding multiple rods simultaneously. The push plate can pass through the fitting opening of the limit frame and the push groove of the stacking plate, ensuring continuous feeding action and improving the feeding cycle.

[0020] 3. The stacking structure uses a combination of fixed and movable baffles for bidirectional limiting, along with an adjustable-angle stacking plate, to ensure that the rods converge in a fixed direction under gravity, preventing scattering and deviation during stacking. The precise fit between the stacking plate and the limiting frame further guarantees the positioning accuracy of the rods. The symmetrical tilt design of the guide arm in the guiding unit ensures even force distribution when the rods roll, preventing collisions. The conveying unit uses a combination of conveying rollers and conical driven rollers. The motor drives the conveying rollers to rotate synchronously via pulleys and a transmission belt, ensuring stable force distribution during rod conveying and preventing surface damage caused by sliding friction. This guarantees the machining accuracy of the valve stem and ensures that the valve stem can fully contact and bear force.

[0021] 4. Adaptable to different types of rod-shaped workpieces: In addition to valve stems, this device can be adapted to the stacking and conveying of various cylindrical workpieces such as shafts and rods by adjusting parameters such as limit spacing, tilt angle, and lifting force. Its application scope covers multiple fields of machining. Attached Figure Description

On the right side of the pusher frame 451, the other end of the second clamping arm 455 corresponds to the other end of the first clamping arm 454. One end of the push plate 456 is detachably placed between the other ends of the first clamping arm 454 and the second clamping arm 455. The push plate 456 is fixed to the first clamping arm 454 by bolts. The push plate 456 is trapezoidal, and the upper wall of the push plate 456 is inclined to the left. The right side wall of the other end of the push plate 456 is an inclined wall. The pusher frame 451 carries and supports the push plate 456. The second hydraulic cylinder 44 drives the lifting and lowering. When the push plate 456 rises, it passes through the fitting port 7 of the limit frame 22 and the stacking structure 5, driving a rod to rise and automatically discharge material. The push plate 456, the first clamping arm 454, and the second clamping arm 455 respectively move through the fitting ports 7 at both ends of the limit frame 22, and the right end of the push plate 456 can pass through the push groove 9 of the stacking plate 51.

Several pushing grooves 9 are equidistantly opened in the middle of the stacking plate 51, and the pushing grooves 9 correspond to the mating openings 7 of the limiting frames 22.

One end of the third hydraulic cylinder body 52 is movably mounted on the upper right wall of the base 1, and the telescopic end of the third hydraulic cylinder body 52 is movably connected to the middle of the lower right wall of the stacking plate 51. The fixed baffle 53 is fixedly mounted on the rear end of the stacking plate 51.

The second bolt 55 is movably screwed onto one end of the movable baffle 54, and the second bolt 55 is pressed against the lower wall of the movable groove 10. The third hydraulic cylinder body 52 drives the stacking plate 51 to rotate, realizing the adjustment of different angles, thereby effectively stacking the rods and rolling them to the left by their own gravity, realizing automatic convergence and facilitating material discharge. The movable baffle 54 can be adjusted in position within the movable groove 10 by means of the second bolt 55, realizing the fitting of rods of different lengths between the fixed baffle 53 and the movable baffle 54. The stacking plate 51 adjusts the tilt angle by the extension and retraction of the third hydraulic cylinder body 52, and the left end of the stacking plate 51 corresponds to and fits the other end of the limiting frame 22.

[0045] More specifically, the core function of the stacking structure 5 is to achieve the orderly stacking and convergence of rods of different sizes; the left side of the stacking plate 51 is movably connected to the side wall of the limiting frame 22 through a transition block, and a push groove 9 corresponding to the fitting port 7 of the limiting frame 22 is opened in the middle, and a moving groove 10 is provided on the upper right wall; the main body 52 of the third hydraulic cylinder is connected to the lower right wall of the stacking plate 51, which can drive the stacking plate 51 to flip and adjust the tilt angle, so that the rods can roll and converge to the left by their own gravity; the fixed baffle 53 is fixed to the rear end of the stacking plate 51, and the moving baffle 54 is movably inserted into the moving groove 10 and is fixed by the second bolt 55, which can adjust the distance with the fixed baffle 53 to adapt to the limiting requirements of rods of different lengths.

[0046] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0047] First, the L-shaped first mounting bracket 21 is fixed to the base 1, providing a stable mounting foundation for the limiting bracket 22 in the material guiding unit 2; the limiting bracket 22 moves in the adjusting groove 6 through the first bolt 23 to adjust the spacing between adjacent limiting brackets 22 and adapt to rods of different diameters; at the same time, the position of the pushing unit 45 needs to be adjusted; the L-shaped fitting port 7 in the middle of the limiting bracket 22 provides a through channel for the pushing unit 45 to ensure the connection between feeding and guiding; the symmetrically inclined guide arm 24 uses the weight of the rod to guide the rod to roll smoothly from the side of the stacking structure 5 to the V-shaped conveying seat 32 of the conveying unit 3, and the conveying seat 32 is supported by the second mounting bracket 31, thereby avoiding deviation or collision;

[0048] In the conveying unit 3, the second mounting frame 31 supports the V-shaped conveying seat 32. One end of the conveying seat 32 is inclined, and the other end is horizontal and fits against the guide arm 24 to ensure smooth support of the rod. The tapered driven rollers 33 are equidistantly embedded at the horizontal end of the conveying seat 32. The tapered structure automatically centers rods of different diameters to ensure the center consistency during conveying. The first hydraulic cylinder 34 drives the roller frame 35 to rise and fall, so that the conveying rollers 36 fit precisely against the rod. The motor 37 is linked with the transmission belt 39 through the pulley 38 to drive multiple conveying rollers 36 to rotate synchronously. Together with the driven rollers 33, they form a clamping drive effect to realize the smooth movement and conveying of the rod.

[0049] The first electric slide rail 41 drives the second electric slide rail 42 and the push unit 45 to move left and right, adjusting the lateral contact position between the push unit 45 and the rod. That is, according to the diameter of the rod, the length of the push plate 456 in the push groove 9 of the stacking plate 51 is adjusted to meet the force application requirements of rods with different diameters. The second electric slide rail 42 drives one of the cylinder seats 43 and the push unit 45 to move back and forth, adjusting the distance between the two push units 45 to meet the force application requirements at both ends of rods with different lengths, thereby matching the position of the limit frame 22. The pair of cylinder seats 43 respectively fix the second hydraulic cylinder 44 to ensure the installation stability and operation accuracy of the push unit 45.

[0050] The slide bar 452 and the spring 453 form a buffer structure. The first clamping arm 454 is movably fitted onto the slide bar 452 and fits against the spring 453. When it is lifted and lowered to reset, the spring 453 can absorb the impact force through deformation to avoid damage to other rods. When the inclined wall surface of the trapezoidal push plate 456 (the upper wall is inclined to the left and the right wall is inclined) contacts the rod, it can only lift a single rod because it matches the extension length of the rod diameter, thus achieving precise separation of a single rod.

[0051] The overall operation is as follows:

[0052] The rod is placed on the stacking plate 51 in the stacking structure 5. By adjusting the extension and retraction of the main body 52 of the third hydraulic cylinder, the tilt angle of the stacking plate 51 is controlled, causing the rod to roll and accumulate to the left under force, and is blocked by multiple limit frames 22.

[0053] The length of the rod is matched, the movable baffle 54 is adjusted, and one end of the movable baffle 54 slides in the movable groove 10. Finally, it is fixed by the second bolt 55, so as to realize the adjustment of the distance between the fixed baffle 53 and the movable baffle 54, thereby limiting the length of the rod.

[0054] When the rods accumulate at the position of the limiting frame 22 and the stacking plate 51, the second hydraulic cylinder 44 in the feeding structure 4 can be activated to extend, driving the push frame 451 to rise, thereby driving the push plate 456 between the first clamping arm 454 and the second clamping arm 455 to rise. The push plate 456 passes through the fitting port 7 at the other end of the limiting frame 22 and the push groove 9 of the stacking plate 51, lifting the rod. When the rod rises to above one end of the guide arm 24, with the help of the inclination of the upper wall of the push plate 456 and the inclination design of the guide arm 24, the rod rolls along the guide arm 24 to the conveying seat 32, thereby contacting the conical driven roller 33.

[0055] At this point, the first hydraulic cylinder 34 can drive the roller frame 35 to descend, so that multiple conveying rollers 36 can be attached to the upper wall of the rod. After the motor 37 is started, the conveying rollers 36 can be rotated synchronously by means of the transmission belt 39 and the pulley 38, thereby driving the rod to be conveyed and moved under force for single rod feeding. It can also accommodate rods of different diameters for clamping and applying force.

[0056] When the length of the rod is short, the position of the limiting bracket 22 is adjusted by moving the first bolt 23 to the adjustment groove 6 of the first mounting bracket 21. The corresponding pushing unit 45 is adjusted by the first electric slide rail 41 and the second electric slide rail 42, so that the push plate 456 in the two adjustment units can push the two ends of the rod to apply force.

[0057] When the push plate 456 descends and resets, the push plate 456 contacts the stacked rods with the right end inclined wall surface and is subjected to force, which drives the first clamping arm 454 and the second clamping arm 455 to move along the slide rod 452 in the telescopic groove 8 of the push frame 451 and compress the spring 453 to store force, thereby obtaining buffer to prevent jamming. The push plate 456 can be retracted to the left by force to pass over the rods and reset to the bottom. Alternatively, the push plate 456 can be moved to the left and descended and reset with the help of the first electric slide rail 41.

[0058] The push plate 456 can fit rods of different diameters. It can be moved to the right by the first electric slide rail 41 to adjust the length of the right end of the push plate 456 in the push groove 9 of the stacking plate 51.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
