Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool tool holders, and in particular to an automatic material turning device for oil anti-sand filter screen tubes. Background Technology

[0002] In recent years, with the continuous development of the global economy, energy demand will continue to grow. As one of the main energy sources, oil production and consumption are also increasing globally, and transportation demand will also increase accordingly. Therefore, the demand for oil pipeline fittings is increasing. The global market size for oil pipeline infrastructure is expected to reach US$110 billion in 2024.

[0003] Metal mesh filter pipes account for a large proportion of transportation equipment in the petroleum, energy, and other industries. Compared with other types of filter pipes, metal mesh filter pipes have excellent characteristics such as strong adaptability, relatively low cost, and good repairability. Therefore, metal mesh filter pipes are becoming increasingly popular in the market.

[0004] However, with the increasing demand for metal mesh filter pipes, the shortcomings of the previous processing technology have gradually become apparent. The main issue is that when welding metal mesh to pipe fittings, it is still necessary to manually move the pipe fittings to the welding position and flip them over. Then, the welded pipe fittings are unloaded manually, resulting in extremely low work efficiency and the inability to position the pipe fittings, which affects the welding efficiency.

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figure 1-2 The embodiments of this utility model include: An automatic material turning device for oilfield sand control filter screen pipes, used to drive the pipe fitting 10 to lift and turn to a designated position, the structure includes: machine tool 1, turning base 21, turning lifting cylinder 22, lifting plate 23, lifting guide column 24, inclined turning plate 25, bracket 26, blocking block 27, rotating shaft 28 and lever cylinder 29.

[0019] The tilting base is connected to the machine tool. The tilting lifting cylinder is set on the tilting base, and its output end is connected to the lifting plate to drive the lifting plate to move up and down. The upper end of the lifting guide column is fixedly connected to the lifting plate, and its lower end is movably connected to the ball guide sleeve 210 on the tilting base to improve the stability of the lifting plate's lifting movement.

[0020] The top surface of the lifting plate is equipped with several inclined tilting plates, and the height of the inclined tilting plates gradually decreases from the feeding direction to the discharging direction, so as to form an inclined surface that tilts in the downward direction, thereby allowing the pipe fitting to be flipped and rolled in the specified direction.

[0021] The bracket is fixedly connected to the lifting plate. The blocking block is rotatably set on the top of the bracket via a rotating shaft. The output end of the lever cylinder set on the bracket or the lifting plate is movably connected to the end of the blocking block near the feeding direction, so as to drive the blocking block to rotate axially around the rotating shaft, causing the other end of the blocking block near the discharge direction to swing up and down, thereby blocking and limiting the pipe on the inclined tilting plate or releasing the pipe.

[0022] Furthermore, the machine tool is connected to two or more sets of automatic return devices, with adjacent sets of pneumatic tipping mechanisms spaced apart. The specific interval can be adjusted in real time according to the length of the pipe to maintain the stability of key movements.

[0023] In some embodiments of this application, the bottom surface of the flipping base is fixedly connected to the machine tool.

[0024] In some other embodiments of this application, the machine tool is provided with a slide rail 11, and the bottom surface of the flipping base is provided with a slider 211 that is movably connected to the slide rail. The slider is fixed to the bottom surface of both sides of the flipping base by screws.

[0025] In the above embodiments of this application, a plurality of quick clamps 212 are provided on the flipping base. A clamping block 213 is fixedly connected to the bottom of the pressure bar in the quick clamp. The quick clamp drives the clamping block to move up and down to abut or move away from the top surface of the machine tool, thereby realizing the locking and unlocking of the automatic flipping mechanism.

[0026] In some embodiments of this application, a horizontal quick clamp is provided on each side of the flipping base, and the two horizontal quick clamps are arranged diagonally.

[0027] Furthermore, loading and unloading mechanisms 12 for storing and / or transporting pipe fittings are provided on both sides of the machine tool.

[0028] Furthermore, the two ends of the lifting plate extend towards the loading and unloading mechanisms on both sides, so that the lifting plate and the loading and unloading mechanisms partially overlap in the horizontal direction, preventing the pipe fittings from leaking through the gaps in the horizontal direction.

[0029] In some embodiments of this application, the lifting plate is provided with multiple inclined tilting plates connected end to end, which can realize assembly line production.

[0030] In some embodiments of this application, the tilting plate and the lifting plate are an integral structure.

[0031] In some other embodiments of this application, the tilting plate is fixedly connected to the lifting plate by screws.

[0032] Before use, adjust the position or spacing of the automatic flipping mechanism according to the length of the pipe fitting, and then rotate the quick clamp to drive the clamping block to press against the machine tool to lock the position of the automatic flipping mechanism.

[0033] When it is necessary to flip the pipe fittings, the pipe fittings move from the upstream loading and unloading mechanism towards the automatic flipping mechanism, either manually or with existing automatic feeding equipment such as conveyor belts or pushing mechanisms. At the same time, the flipping lifting cylinder drives the lifting plate to rise (at this time, the blocking block is in a tilted state) to lift the pipe fittings so that they can fall onto the inclined flipping plate. Because the inclined flipping plate has an inclination angle, the pipe fittings will automatically roll along the inclined flipping plate in the designated direction until they reach the target position and are blocked by the blocking block, thus completing the flipping. The flipping lifting cylinder then drives the lifting plate to descend, causing the pipe fittings to fall to the welding position, ready for welding.

[0034] After the pipe fitting is welded, the tilting and lifting cylinder lifts the pipe fitting again through the lifting plate, so that the pipe fitting moves to the target height (level with or slightly higher than the loading and unloading mechanism). The lever cylinder is opened to drive the blocking block to flip to a horizontal state. Since there is no longer the restriction of the blocking block, the pipe fitting will continue to roll down along the inclined tilting plate until the pipe fitting falls on the loading and unloading mechanism downstream of the automatic tilting mechanism, thus completing the unloading.

[0035] In addition, when two inclined tilting plates are installed on the lifting plate, two pipe fittings can simultaneously fall on the corresponding inclined tilting plates (i.e., the first and second inclined tilting plates). Since there is a certain height difference at the connection point of the two adjacent inclined tilting plates, this height difference can be used to restrict the pipe fittings closer to the loading direction. The pipe fittings located on the first inclined tilting plate closer to the unloading direction need to be restricted by the blocking block to prevent the two pipe fittings from being close together. After the pipe fitting closer to the unloading direction has been welded, the tilting and lifting cylinder first lifts the two pipe fittings. After welding, the pipe fitting loses the effect of the blocking block and moves to the loading and unloading mechanism. The pipe fitting that has not been welded can move from the current second inclined tilting plate to the subsequent first inclined tilting plate under the action of manual or automatic feeding equipment and be blocked by the blocking block. At the same time, a new unprocessed pipe fitting moves from the loading and unloading mechanism to the second inclined tilting plate, thereby realizing assembly line production.

[0036] The beneficial effects of this utility model of an automatic turning device for oilfield sand control filter screen pipes are: by using an inclined turning plate to drive the pipes to move automatically to the designated position, the pipes are transferred, turned and initially positioned, which facilitates subsequent welding operations, effectively improves the efficiency and production capacity of pipe turning, and also helps to improve product quality.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
