Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, specifically relating to an adjustable gripping device. Background Technology

[0002] Lasers possess high coherence, directionality, and intensity, making it easy to achieve high optical energy densities. Laser weakening technology uses a focused high-energy laser beam to melt or vaporize materials, and then uses an auxiliary gas to extract the melted or oxidized material, forming the processed surface. This process offers significant advantages such as wide applicability, minimal deformation, high precision, energy and material savings, low pollution, and long-distance processing. Laser weakening is suitable for most common materials. During laser cutting, a suction cup gripper is typically used to hold and fix the material. Since the material size and processing position change during processing, the suction cup position also needs to be adjusted. Current solutions mainly adjust the position by replacing different types of suction cups or using cylinders to drive the suction cups. Replacing the suction cups affects the production efficiency of the laser cutting device, while using conventional cylinder-driven suction cups suffers from large repeatability errors, insufficient positioning accuracy, and low efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] Reference Figure 1-2 This utility model provides an adjustable gripping device, including a drive gear 4 and multiple transmission components. The transmission components include a transmission gear 5 and a support 6. The transmission gear 5 meshes with the drive gear 4. One end of the support 6 is connected to the transmission gear 5, and the other end is connected to a suction cup 8, preferably a vacuum suction cup 8, via an adjusting element. The adjusting element is used to adjust the relative distance between the suction cup 8 and the support 6, preferably to adjust the relative vertical distance between the suction cup 8 and the support 6. In use, by adjusting the suction cup 8 to a suitable position via the adjusting element, rotating the drive gear 4 causes the meshing transmission gear 5 to rotate synchronously, and the support 6 drives the suction cup 8 to rotate continuously, ensuring that the suction cup 8 can operate within a wide range.

[0023] Specifically, the adjusting component includes an adjusting rod 7 with external threads; the bracket 6 has a mounting hole; one end of the adjusting rod 7 is connected to the suction cup 8, and the other end is inserted into the mounting hole and connected to the bracket 6 via a nut 9. In use, the adjusting rod 7 is inserted into the mounting hole and adjusted to the desired height. Then, the nut 9 is fitted onto the adjusting rod 7 and tightened to fix the adjusting rod 7 and the suction cup 8 below it in that position. Generally, two nuts 9 are provided, one above and one below the mounting hole, to ensure a stable connection between the adjusting rod 7 and the bracket 6.

[0024] Optionally, the adjustable gripping device provided by this utility model further includes a drive component for driving the active gear 4 to rotate.

[0025] In one detailed embodiment, the driving component includes a knob 1 and a guide shaft 2; one end of the guide shaft 2 is connected to the knob 1, and the other end is connected to the drive gear 4. By manually rotating the knob 1, the guide shaft 2 drives the drive gear 4 to rotate.

[0026] In another implementation, such as Figure 1 As shown, the bracket 6 includes an upper support plate 601, an adapter plate 602, and a lower support plate 603. The adapter plate 602 connects the upper support plate 601 and the lower support plate 603, forming a Z-shaped bracket 6. The upper support plate 601 is fixedly connected to the transmission gear 5. The lower support plate 603 is connected to the suction cup 8 via an adjusting member. The Z-shaped bracket 6 design avoids limiting the rotation range of the suction cup 8 due to the diameters of the drive gear 4 and the transmission gear 5, compared to directly mounting the suction cup 8 vertically below the transmission gear 5. Optionally, the upper support plate 601 is fixed to the lower surface of the transmission gear 5 via a connecting shaft and bolt bushing.

[0027] Furthermore, the adjustable gripping device also includes a mounting plate 3; the drive gear 4 and the transmission gear 5 are respectively rotatably mounted on the mounting plate 3.

[0028] In a more detailed embodiment, the mounting plate 3 is provided with a first rotating shaft and a plurality of second rotating shafts corresponding one-to-one with the transmission gears 5; the driving gear 4 is rotatably sleeved on the first rotating shaft; the transmission gears 5 are rotatably sleeved on the second rotating shafts. The second rotating shafts are arranged around the first rotating shaft according to the actual installation needs of the suction cup 8, and provide support for the driving gear 4 and the transmission gears 5 through the rotating shafts.

[0029] To prevent the drive gear 4 and transmission gear 5 from shifting during rotation and affecting the operation, a first limiting member is provided on the first rotating shaft to restrict the drive gear 4 from moving axially along the first rotating shaft; a second limiting member is provided on the second rotating shaft to restrict the transmission gear 5 from moving axially along the second rotating shaft.

[0030] Optionally, the first and second rotating shafts are threaded, and both the first and second limiting members can be nuts. The nuts are fitted onto the corresponding rotating shafts, leaving space between the mounting plate 3 and the nut that does not affect the rotation of the gears. At the same time, the driving gear 4 and the transmission gear 5 are constrained between the mounting plate 3 and the nut. The specific design is based on the thickness of the driving gear 4 and the transmission gear 5, ensuring that the rotation of the gears is not affected and that the gears will not fall off.

[0031] In one embodiment, multiple transmission gears 5 of the above-mentioned transmission components are arranged at equal intervals around the drive gear 4 to balance the adsorption sites of multiple suction cups 8 and ensure gripping stability.

[0032] Example 1:

[0033] This embodiment provides an adjustable gripping device, including a mounting plate 3, a drive gear 4, four transmission components, a knob 1, and a guide shaft 2;

[0034] The bottom surface of the mounting plate 3 is vertically provided with a first rotating axis and four second rotating axes arranged at equal intervals around the first rotating axis.

[0035] The drive gear 4 is sleeved on the first rotating shaft; the upper end of the guide shaft 2 is connected to the knob 1, and the lower end passes through the mounting plate 3 and is connected to the upper surface of the drive gear 4; the axes of the guide shaft 2, the first rotating shaft and the drive gear 4 coincide.

[0036] The transmission assembly includes a transmission gear 5, a bracket 6, and an adjusting rod 7 with external threads; the transmission gear 5 is centrally sleeved on the corresponding second rotating shaft and meshes with the driving gear 4; the first rotating shaft is provided with a first limiting member for restricting the driving gear 4 from moving axially along the first rotating shaft; the second rotating shaft is provided with a second limiting member for restricting the transmission gear 5 from moving axially along the second rotating shaft.

[0037] The bracket 6 includes an upper support plate 601, an adapter plate 602, and a lower support plate 603; the adapter plate 602 connects the upper support plate 601 and the lower support plate 603, forming a bracket 6 with a Z-shaped cross section; the upper support plate 601 is horizontally fixed to the lower surface of the transmission gear 5 through a connecting shaft and a bolt bushing; the lower support plate 603 has a mounting hole; the lower end of the adjusting rod 7 is connected to a vacuum suction cup 8, and the upper end is inserted into the mounting hole and connected to the lower support plate 603 through a nut 9; the straight-line distance between the center of the driving gear 4 and the center of the suction cup 8 in the horizontal direction is 200mm.

[0038] In use, loosen nut 9 to change the length of adjusting rod 7 passing through the mounting hole, and adjust the vertical position of suction cup 8. After adjusting suction cup 8 to the desired height, tighten nut 9 to fix suction cup 8 in that position. Rotate knob 1, which drives drive gear 4 to rotate via guide shaft 2. The four transmission gears 5 meshing with drive gear 4 rotate synchronously, thereby driving the four suction cups 8 fixed by bracket 6 to rotate on a circumference with a diameter of 400 mm, reciprocating in a circular motion, thus adjusting the working position of suction cup 8 in the circumferential direction.
