Description

Technical Field

[0001] The present invention relates to the technical field of valve delivery, in particular to an automatic delivery tool for valve pipe fittings. Background Art

[0002] Valve fittings take the valve body as the core functional unit, and achieve sealed connection with the pipeline system through flange connectors. They are supplemented by functional accessories such as risers to expand the system integration capability, and together they constitute the basic unit of industrial fluid control. As a key component with both control and connection functions in the pipeline system, it realizes flow direction switching, pressure regulation and flow control of media such as water, gas, and oil by driving and controlling the opening and closing parts inside the valve body; at the same time, relying on the structured connection of flanges, elbows, tees and other pipe fittings, it completes the spatial layout construction, pipe diameter transformation and shape reconstruction of the pipeline system.

[0003] Currently, chain or belt conveyors are the mainstream method for conveying valve and pipe fitting shells after production. Chain conveyors are driven by sprockets and chains. Although they can convey stably, they have large mechanical friction and obvious noise during operation. Long-term use will cause wear of the chain sprockets, resulting in reduced transmission accuracy and inaccurate pipe conveying positions. Belt conveyors drive pipe fittings by friction. Due to the lack of active clamping, pipe flanges are prone to displacement and tilt during transportation. In order to ensure the accuracy of subsequent processing, calibration stations need to be added, which not only makes the process more complicated and slows down production, but also increases the maintenance cost of the equipment.

[0033] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figures 1 to 10 As shown, the present invention provides an embodiment:

[0035] A valve and pipe automatic feeding tool includes a tool base 1, a conveying assembly 2, a guide assembly 3, and a circulation assembly 4 are arranged inside the tool base 1, and the conveying assembly 2 includes a support plate 21, a feeding mechanism 22, and a driving mechanism 23. The support plate 21 is fixedly connected to the bottom inner wall of the tool base 1. The tool base 1 has symmetrically fixed mounting seats 24. The tops of the support plates 21 are fixedly connected to support seats 26.

[0036] The feeding mechanism 22 includes a feeding seat 221 and a connecting seat 222. The bottom of the feeding seat 221 is symmetrically fixedly connected to a driving block 224. The bottom of the connecting seat 222 is fixedly connected to a movable frame 223. The movable frame 223 is slidably connected to the inner wall of the bottom end of the tooling base 1. The connecting seat 222 is longitudinally slidably connected to the driving block 224. The outer side of the feeding seat 221 is rotatably connected to a plurality of clamping blocks 226. A connecting rod 225 is rotatably connected between the connecting seat 222 and the clamping block 226.

[0037] There are four driving mechanisms 23, and the four driving mechanisms 23 are divided into two groups with two as a group. The driving mechanism 23 includes a movable seat 231, a limit block 235 and a mounting shaft 236. The limit block 235 is fixedly connected to the mounting shaft 236. The mounting shaft 236 is fixedly installed inside the mounting seat 24. The outer side of the mounting shaft 236 is rotatably connected to the mounting sleeve 237. The movable seat 231 is fixedly connected to the mounting sleeve 237. The movable seat 231 is internally slidably connected to the slider 233. A spring 232 is fixedly connected between the slider 233 and the inner wall of the movable seat 231. The slider 233 is internally rotatably connected to the fixed rod 234. The driving block 224 is rotatably connected to the fixed rod 234.

[0038] A motor 25 is fixedly installed on the outer side of the mounting seat 24, and a driven wheel 239 is fixedly connected to the outer side of the mounting sleeve 237. The output shaft of the motor 25 passes through the mounting seat 24 and is fixedly connected to the driving wheel 238. The driving wheel 238 and the driven wheel 239 are engaged with each other. The two mounting sleeves 237 in each group are connected by a synchronous belt 2310. The outer side of the fixed rod 234 is rotatably connected to the roller 2311, and the roller 2311 is slidably connected between the limit block 235 and the support plate 21.

[0039] In practical application, the embodiment of the present invention realizes the automatic delivery and installation of valve pipes through the cooperation of the conveying component 2, the guiding component 3 and the circulation component 4;

[0040] When working, Figures 4 to 8 As shown, the motor 25 drives the driving wheel 238 to engage with the driven wheel 239, driving the installation sleeve 237 to rotate, causing the movable seat 231 to rotate synchronously. The slider 233 slides radially along the movable seat 231 under the action of the pre-tightening force of the spring 1 232. The roller 2311 inside the slider converts the rotational motion into the rectangular track motion of the fixed rod 234 under the constraint of the track between the limit block 235 and the support plate 21. The fixed rod 234 drives the feeding seat 221 to perform reciprocating linear motion through the driving block 224, thereby realizing the precise feeding and installation of pipe fittings.

[0041] like Figure 2 、 Figure 4 and Figure 5As shown, during the rising stroke of the feeding seat 221, the connecting rod 225 drives the clamping block 226 to close synchronously, and is slidably connected to the inner wall of the bottom end of the tooling base 1 through the movable frame 223, and the connecting seat 222 is longitudinally slidably connected to the driving block 224, so that the connecting seat 222 can only move synchronously with the driving block 224 laterally, forming an embracing clamp for the pipe fitting to ensure positioning accuracy. At the same time, the two sets of driving mechanisms 23 achieve phase synchronization through the synchronous belt 2310 to eliminate motion interference, thereby replacing sliding contact with rolling friction, reducing mechanical loss and noise, and avoiding the problem of reduced accuracy of traditional chain transmission. The rectangular trajectory optimizes space utilization, and the active clamping mechanism eliminates the calibration station, which significantly improves production efficiency.

[0042] like Figure 2 、 Figure 3 and Figure 9 As shown, the guide assembly 3 includes a conveyor belt 1 31, a conveyor belt 2 32 and a support frame 33. A driving roller 36, a support roller 37 and a support wheel 38 are rotatably installed on the top of the tooling base 1. The conveyor belt 1 31 is transmission-connected between the driving roller 36 and the support roller 37. The conveyor belt 2 32 is transmission-connected between the driving roller 36 and the support wheel 38. The support frame 33 is slidingly connected to the top of the tooling base 1. The bottom of the support frame 33 is symmetrically fixedly connected to the guide plate 34. The inside of the support frame 33 is symmetrically slidingly connected to the fixed block 35. The fixed block 35 is fixedly connected to the top of the tooling base 1.

[0043] In actual application of the embodiment of the present invention, the driving roller 36 is driven to rotate by a matching driving source, and the friction force drives the conveyor belt 1 31 and the conveyor belt 2 32 to run respectively, thereby forming a pipe conveying power. The valve pipe fittings are ejected by the feeding mechanism 42 and fall onto the conveyor belt 1 31, and the posture is calibrated by using the geometric adaptability of the guide plate 34 at the bottom of the support frame 33 and the pipe flange. When the pipe fittings fall on the designated work position outside the two conveyor belts 32, the conveyor belt 2 32 runs at a constant linear speed, and drives the pipe fittings to be transported smoothly by the surface friction force, so that it docks with the conveying assembly 2 to complete the delivery. The pipe fittings that do not meet the guidance requirements cannot be stably positioned outside the conveyor belt 2 32 due to posture deviation, and will slide from the gap between the two conveyor belts 2 32. In addition, the support frame 33 slides on the top of the tooling base 1 through the fixed block 35, and the position of the guide plate 34 can be flexibly adjusted to adapt to the guidance requirements of the pipe fittings.

[0044] like Figure 2 、 Figure 3 、 Figure 10 and Figure 11As shown, the circulation component 4 includes a blanking plate 41, a loading mechanism 42 and a fixed plate 43. The blanking plate 41 is fixedly connected to the top of the fixed plate 43, and the fixed plate 43 is fixedly connected to the bottom of the tooling base 1. The loading mechanism 42 includes a loading seat 421 and a movable plate 423. The top of the movable plate 423 is fixedly connected with a movable block 428, and the bottom of the loading seat 421 is symmetrically rotatably connected with a support shaft 424, and the outer side of the support shaft 424 is fixedly connected with an eccentric cam 425. The bottom of the movable plate 423 is rotatably connected with a connecting rod 426, and the connecting rod 426 is rotatably connected to the eccentric cam 425. The outer side of the movable plate 423 is symmetrically slidably connected with a support block 422, and a spring 2 427 is fixedly connected between the support block 422 and the movable plate 423. The support block 422 is slidably connected to the inner wall of the loading seat 421.

[0045] When the embodiment of the present invention is actually used, the valve pipe fittings that have not completed the guide calibration slide from the gap between the two conveyor belts 32, and fall accurately into the loading seat 421 of the loading mechanism 42 through the inclined diversion effect of the blanking plate 41. The support shaft 424 is driven by a matching drive source, and drives the outer eccentric cam 425 to rotate, and drives the movable plate 423 to perform reciprocating lifting motion in the support block 422 through the connecting rod 426. When the loading seat 421 rises to the top of the stroke, the movable plate 423 continues to move upward to compress the spring 427, and push the pipe fitting out of the loading seat 421, so that the pipe fitting moves and calibrates along the guide assembly 3. The uncalibrated pipe fittings flow back to the loading mechanism 42 through the blanking plate 41, forming a cycle, thereby improving the loading efficiency and accuracy, effectively avoiding manual intervention, and improving the loading efficiency and equipment operation continuity.
