A gantry numerical control machine tool convenient for feeding

Abstract

This utility model belongs to the technical field of gantry CNC machine tools, specifically disclosing a gantry CNC machine tool with convenient loading. The utility model includes a gantry CNC machine tool body, with a processing conveyor table on one side. The processing conveyor table has a loading assembly inside, which includes an adjustment unit and a partition unit. The adjustment unit includes two moving plates. The spacing between the moving plates is adjusted by a cylinder driven by the adjustment unit of the loading assembly, allowing for quick adaptation to workpieces of different widths. This avoids the protective failure caused by traditional fixed-spacing partitions due to workpieces being too wide or causing loading jams due to workpieces being too narrow, reducing manual adjustment time. Furthermore, the partition unit uses a multi-stage telescopic partition design, with an electric push rod driving the top plate to synchronously raise and lower the partitions, accurately matching the workpiece height and effectively preventing workpieces of different heights from sliding off the conveyor processing table due to shaking or collision.

Description

Technical Field

[0001] This application relates to the field of gantry CNC machine tool technology, and more specifically, to a gantry CNC machine tool with convenient loading. Background Technology

[0002] CNC machine tools generally consist of a CNC system, a servo system including a servo motor and a detection feedback device, a high-voltage control cabinet, a machine tool body, and various auxiliary devices. They are generally used to process groove-type workpieces, such as splines on splined shafts, keyways on shafts, and teeth on gears. Of course, they can also perform planar milling. Small milling machines are generally horizontal, while large milling machines are gantry-type.

[0003] A search revealed that patent CN220074043U discloses a convenient gantry CNC machine tool for loading materials. The machine tool includes a gantry CNC machine tool body. A processing table is mounted on the inner surface of the machine tool body. Conveyor belts are mounted on both sides of the processing table. Two U-shaped frames are fixedly connected to the surface of the processing table. A rotating rod is fixedly connected to the inner surface of each U-shaped frame. A support plate is rotatably connected to the arc surface of the rotating rod. A baffle is fixedly connected to the upper surface of the support plate. A sliding rod is fixedly connected to one side of each U-shaped frame. An operating plate is slidably connected to the arc surface of the sliding rod. A plug rod is fixedly connected to the end of the operating plate near the U-shaped frame. This convenient gantry CNC machine tool, through the baffle, effectively prevents items from falling off the conveyor belt, avoiding damage caused by external shaking or accidental contact by workers.

[0004] The aforementioned patent describes the effect of a baffle preventing items from falling during conveyor belt transport. However, the baffle is fixed by the rigid fit between the insert rod and the slot and the elastic force of the first spring. After long-term use, the spring is prone to fatigue, which can cause the insert rod to loosen. Furthermore, the baffle is difficult to adjust in height according to different sizes of items, making it difficult to adapt to various workpieces. This can easily lead to oversized items colliding with the baffle, increasing the risk of damage. Utility Model Content

[0005] To address the aforementioned issues, this application provides a gantry CNC machine tool with convenient loading.

[0006] The gantry CNC machine tool with convenient loading provided in this application adopts the following technical solution:

[0007] A gantry CNC machine tool with convenient loading includes a gantry CNC machine tool body, a processing conveyor table is provided on one side of the gantry CNC machine tool body, and a loading component is provided inside the processing conveyor table. The loading component includes an adjustment unit and a partition unit.

[0008] The adjustment unit includes two movable plates. The processing conveyor table is equipped with a cylinder inside, which is used to drive the two movable plates to adjust the distance between them.

[0009] The partition unit is set into two groups. Each group of partition units includes a first baffle, a second baffle, and a third baffle. The first baffle, the second baffle, and the third baffle can separate items of different sizes by extending and retracting.

[0010] Furthermore, the processing conveyor table has an internal cavity, and the cylinder is fixedly installed on one side of the inner wall of the cavity. The output end of the cylinder is fixedly connected to a fixed plate, and there are connecting rods on both sides of the fixed plate. The bottom ends of the two connecting rods are rotatably connected to the outer walls of the fixed plate.

[0011] Furthermore, two grooves are provided at the top of the cavity, and connecting seats are provided at the bottom of the two movable plates. The two connecting seats are slidably connected to the corresponding grooves, and the two connecting seats are rotatably connected to the top of the corresponding connecting rods after passing through the corresponding grooves.

[0012] Through the above technical solution, the adjustment unit can adjust the distance between the two sets of partition units.

[0013] Furthermore, the bottom of each first baffle is fixedly connected to the top of the corresponding movable plate, and the inner walls of each first baffle and second baffle are provided with limiting grooves. Each second baffle and the top plate are slidably connected to the corresponding limiting grooves. Each second baffle is located inside the corresponding first baffle, and each third baffle is located inside the corresponding second baffle.

[0014] Furthermore, a top plate is fixedly connected to the top of each third baffle, and electric push rods are fixedly connected to both ends of the top of each movable plate. The output end of each electric push rod is fixedly connected to the bottom of the corresponding top plate.

[0015] Through the above technical solution, the partition component can separate items of different heights.

[0016] Furthermore, each movable plate has a mounting block fixedly connected to its bottom, each connector has an internal mounting groove, each mounting block is inserted into the corresponding mounting groove, and each mounting block has a threaded groove on one side.

[0017] Furthermore, each connector has a through hole on one side and a bolt on one side, with each bolt passing through the corresponding through hole and threaded into the corresponding threaded groove.

[0018] The above technical solutions simplify the maintenance and replacement process.

[0019] Furthermore, both ends of the top of the processing conveyor table are fixedly connected to a placement box, the structure of which is compatible with the structure of the first baffle.

[0020] The above technical solutions reduce the dust and debris accumulated on the baffle due to long-term exposure, thus extending its service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This invention uses a cylinder-driven moving plate adjustment unit in the feeding assembly to adjust the spacing, which can quickly adapt to workpieces of different widths. This avoids the protective failure caused by workpieces that are too wide or the feeding jam caused by workpieces that are too narrow, which is a problem with traditional fixed spacing baffles. It also reduces manual adjustment time. Furthermore, the baffle unit uses a multi-stage telescopic baffle setting, and the top plate is driven by an electric push rod to drive the baffle to rise and fall synchronously. This can accurately match the height of the workpiece and effectively prevent workpieces of different heights from sliding off the conveyor processing table due to shaking or collision.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Reference Figures 1-7 A gantry CNC machine tool with convenient loading includes a gantry CNC machine tool body 1. A processing conveyor table 2 is provided on one side of the gantry CNC machine tool body 1. The processing conveyor table 2 is provided with a loading component inside. The loading component includes an adjustment unit and a partition unit.

[0033] The adjustment unit includes two movable plates 9. The processing conveyor table 2 is equipped with a cylinder 5 inside, which is used to drive the two movable plates 9 to adjust the distance between them.

[0034] The partition unit is set into two groups. Each group of partition units includes a first baffle 3, a second baffle 10 and a third baffle 11. The first baffle 3, the second baffle 10 and the third baffle 11 can separate items of different sizes by extending and retracting.

[0035] Reference Figures 1-7 The processing conveyor table 2 has a cavity 4 inside. The cylinder 5 is fixedly installed on one side of the inner wall of the cavity 4. The output end of the cylinder 5 is fixedly connected to the fixing plate 6. The fixing plate 6 has connecting rods 7 on both sides. The bottom ends of the two connecting rods 7 are rotatably connected to the outer walls of the fixing plate 6. The top of the cavity 4 has two sliding grooves 19. The bottom of the two moving plates 9 is provided with connecting seats 8. The two connecting seats 8 are slidably connected to the corresponding sliding grooves 19 respectively. The two connecting seats 8 pass through the corresponding sliding grooves 19 and are rotatably connected to the top of the corresponding connecting rods 7.

[0036] The spacing between the two sets of partition units can be adjusted by the adjustment unit. Specifically, in order to make the two sets of partition units adaptable to items of different widths and avoid the partitions from failing due to excessive width or affecting feeding due to excessive narrowness, the spacing between the two sets of partition units needs to be adjusted by the adjustment unit. First, the cylinder 5 is started. The output end of the cylinder 5 drives the fixed plate 6 to move horizontally in the cavity 4. When the fixed plate 6 moves, it will drive the connecting rods 7 on both sides to move synchronously. Since the bottom ends of the two connecting rods 7 are rotatably connected to the fixed plate 6 and the top ends are rotatably connected to the corresponding connecting seats 8 respectively, and the connecting seats 8 are restricted by the slide groove 19 and can only slide along the slide groove 19, the movement of the fixed plate 6 will push the two connecting seats 8 closer or further apart in the slide groove 19 through the connecting rods 7, thereby driving the two moving plates 9 to move synchronously, realizing the adjustment of the spacing between the two sets of partition units to adapt to the partition requirements of items of different widths.

[0037] Reference Figures 1-5 The bottom of each first baffle 3 is fixedly connected to the top of the corresponding movable plate 9. Each first baffle 3 and second baffle 10 has a limiting groove 12 on its inner wall. Each second baffle 10 and top plate 13 are slidably connected to the corresponding limiting groove 12. Each second baffle 10 is located inside the corresponding first baffle 3. Each third baffle 11 is located inside the corresponding second baffle 10. Each third baffle 11 has a top plate 13 fixedly connected to its top. Each movable plate 9 has an electric push rod 14 fixedly connected to both ends of its top. The output end of each electric push rod 14 is fixedly connected to the bottom of the corresponding top plate 13.

[0038] The baffle assembly can separate items of different heights. Specifically, when conveying items of different heights (e.g., from thin sheet metal to thick castings) or items of different heights (e.g., small castings 10cm high and large sheet metal 50cm high), to prevent items from slipping out due to exceeding the baffle's protection range or to avoid the baffle being too high and affecting normal loading, the baffle height needs to be adjusted using the baffle assembly. First, the electric push rod 14 is activated, and its output end extends and retracts, causing the top plate 13 to move up and down. The top plate 13 simultaneously causes the third baffle 11 to slide within the limiting groove 12 of the second baffle 10, while the second baffle 10 slides simultaneously within the limiting groove 12 of the first baffle 3, thereby achieving adjustment of the overall baffle height (e.g., for a 10cm high casting, adjusting the baffle height to 15cm is sufficient for effective protection; for a 50cm high sheet metal, adjusting the baffle height to 60cm ensures that it will not slip off the processing table even if it is hit).

[0039] For example, when conveying a square steel block with a height of 30cm, if the initial height of the baffle is 20cm, the steel block is prone to tipping off the top of the baffle while shaking. After the baffle is raised to 35cm by the electric push rod 14, the sides of the steel block are completely blocked by the baffle, and even if it is accidentally touched by the staff, it can be stably kept on the processing conveyor table.

[0040] The spacing can be adjusted by the cylinder 5 driving the moving plate 9 through the adjustment unit of the feeding component. It can quickly adapt to workpieces of different widths, avoiding the failure of protection caused by the workpiece being too wide or the feeding jam caused by the workpiece being too narrow due to the traditional fixed spacing baffle. It reduces the manual adjustment time. In addition, the baffle unit adopts a multi-level telescopic baffle setting. The electric push rod 14 drives the top plate 13 to drive the baffle to rise and fall synchronously. It can accurately match the height of the workpiece and effectively prevent workpieces of different heights from sliding out of the conveyor processing table 2 due to shaking or collision.

[0041] Reference Figure 5Each movable plate 9 has a mounting block 15 fixedly connected to its bottom. Each connecting seat 8 has an internal mounting groove. Each mounting block 15 is inserted into the corresponding mounting groove. Each mounting block 15 has a threaded groove 17 on one side. Each connecting seat 8 has a through hole 16 on one side. Each connecting seat 8 has a bolt 18 on one side. Each bolt 18 passes through the corresponding through hole 16 and is threaded into the corresponding threaded groove 17.

[0042] The quick positioning and installation of the moving plate 9 and the connecting seat 8 are achieved by inserting the mounting block 15 into the mounting slot, which avoids the moving plate 9 from becoming loose due to vibration when it drives the baffle to adjust or transport the workpiece. When the moving plate 9 and the baffle are worn and need to be replaced, they can be separated by simply unscrewing the bolt 18 without disassembling the whole thing, which greatly simplifies the maintenance and replacement process and reduces maintenance costs and time.

[0043] Reference Figures 1-3 Both ends of the top of the processing conveyor table 2 are fixedly connected to a placement box 20, and the structure of the placement box 20 is adapted to the structure of the first baffle 3.

[0044] By setting the placement box 20, the baffle can be retracted to its shortest state when it is not needed (e.g., Figure 2 As shown, the entire baffle is placed inside the storage box, which can store the baffle and prevent it from being exposed and taking up space or deformed due to collision. It can also keep the surface of the processing table clean and reduce the dust and debris accumulated on the baffle due to long-term exposure, thus extending its service life.

[0045] Working principle: When conveying items of different heights (e.g., from thin sheet metal to thick castings), or when conveying items of different heights (e.g., small castings 10cm high and large sheet metal 50cm high), to prevent items from slipping out due to exceeding the baffle's protection range, or to avoid the baffle being too high and affecting normal feeding, the baffle height needs to be adjusted through the baffle assembly. First, the electric push rod 14 is activated, and its output end extends and retracts, driving the top plate 13 to move up and down. The top plate 13 simultaneously drives the third baffle 11 to slide within the limiting groove 12 of the second baffle 10, while the second baffle 10 slides simultaneously within the limiting groove 12 of the first baffle 3, thereby achieving the adjustment of the overall baffle height (e.g., for a 10cm high casting, adjusting the baffle height to 15cm is sufficient for effective protection; for a 50cm high sheet metal, adjusting the baffle height to 60cm ensures that it will not slip off the processing table even if it is hit).

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
