Description

Technical Field

[0001] This utility model belongs to the field of positioning device technology. Specifically, this utility model relates to a vacuum suction cup center positioning device. Background Technology

[0002] When using vacuum suction cups to position cylindrical products, it is usually necessary to manually place the product on the top of the suction cup and manually position the center of the cylindrical product to the center of the suction cup. This process requires the user to have a certain level of skill.

[0003] A patent specification published on February 2, 2021, with patent number 202020804015.4, discloses a precise positioning device for the outer circle of a cylinder. The device includes an elastic expansion sleeve, an outer fixing sleeve, a threaded pull rod, a handle, and a connecting plate. The outer fixing sleeve is mounted on the connecting plate, and the threaded pull rod is threaded to the center of the outer fixing sleeve. One end of the threaded pull rod is connected to the elastic expansion sleeve, and the other end passes through the connecting plate and connects to the handle. The key feature is that the elastic expansion sleeve is embedded within the outer fixing sleeve, and the elastic expansion sleeve and the outer fixing sleeve are in a tapered sliding fit. When the handle is rotated, the threaded pull rod and the elastic expansion sleeve rotate together. Because the elastic expansion sleeve and the outer fixing sleeve are in a tapered sliding fit, the elastic expansion sleeve clamps the product downwards. Under the action of the tapered surface of the outer fixing sleeve, the elastic expansion sleeve contracts inwards towards the center until it presses against the outer circle of the product, thus clamping and positioning the outer circle of the product. The precise positioning device for the outer circle of a cylinder will not be affected by errors in the outer diameter of the cylindrical product, thus ensuring the accuracy of the axis center positioning.

[0004] In existing technologies, when placing cylindrical products on suction cups for fixation, concentricity can only be achieved through manual positioning, which is inconvenient for processing. Utility Model Content

[0007] The suction cup has a mounting housing on its outer side, and the electric push rod is mounted on the mounting housing.

[0008] At least two electric push rods are provided on the outer edge of the suction cup, and the electric push rods are evenly distributed on the suction cup in a circle with the center of the suction cup as the center.

[0009] The fixing plate is equipped with a sponge pad.

[0010] It also includes a fixing seat located outside the suction cup, the fixing seat is provided with a sliding plate, the suction cup is provided with an outer ring, a locking bolt is provided between the sliding plate and the outer ring, and the sliding plate is provided with a threaded hole.

[0011] The fixed base is provided with a sliding groove, and the sliding plate is disposed in the sliding groove.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0022] Please see Figure 1-3 A vacuum suction cup center positioning device is disclosed. The positioning device consists of an electric push rod 5 mounted on the suction cup 1 and a fixing plate 6 mounted at the end of the electric push rod 5. The fixing plate 6 is distributed in a circle around the center of the suction cup 1 on the outer edge of the suction cup 1. By using the circumferentially distributed electric push rod 5 and the fixing plate 6, the synchronously moving and extending electric push rod 5 pushes the fixing plate 6 to fix the cylindrical workpiece placed on the suction cup 1 from all sides, thus achieving the purpose of fixing the cylindrical workpiece and concentricity with the center of the suction cup 1.

[0023] The suction cup 1 has a mounting housing 3 on its outer side, and the electric push rod 5 is mounted on the mounting housing 3; the mounting housing 3 is used to protect the motor part of the electric push rod 5.

[0024] At least two electric push rods 5 are provided on the outer edge of the suction cup 1. The electric push rods 5 are evenly distributed in a circle around the center of the suction cup 1. As the electric push rods 5 push the fixed plate 6 to move, the cylindrical workpiece on the suction cup 1 can be made to contact the electric push rods 5 evenly, ensuring that the center of the cylindrical workpiece can move to the center of the suction cup 1.

[0025] The fixing plate 6 is provided with a sponge pad 7, which allows the cylindrical workpiece to have a larger contact area with the fixing plate 6, reducing the possibility of offset and avoiding skewing.

[0026] It also includes a fixing seat 4 located outside the suction cup 1. The fixing seat 4 is provided with a sliding plate 9. An outer ring 2 is provided outside the suction cup 1. A locking bolt 10 is provided between the sliding plate 9 and the outer ring 2. A threaded hole 11 is provided on the sliding plate 9. The outer ring 2 and the suction cup 1 are fixed by the sliding plate 9 to prevent the suction cup 1 from sliding.

[0027] The mounting base 4 is provided with a sliding groove 8, and a sliding plate 9 is disposed in the sliding groove 8; the sliding plate 9 can move along the sliding groove 8 to accommodate suction cups 1 of different sizes.

[0028] One end of the sliding plate 9 is provided with a limiting plate 12, and the other end of the sliding plate 9 is provided with an extension limiting block 13; to prevent the sliding plate 9 from detaching from the slide groove 8.

[0029] The sliding plates 9 are arranged in pairs at the upper and lower ends of the fixed base 4, and the sliding plates 9 are located on the upper and lower sides of the suction cup 1; the suction cup 1 is fixed from the upper and lower sides, making the fixation more secure and reducing shaking.

[0030] The fixing base 4 is evenly distributed around the outside of the suction cup 1 in a circle; in this way, after the suction cup 1 is fixed, the sliding plate 9, due to its different orientation, can fix the suction cup 1 in place through the cooperation between the sliding plate 9 and the fixing base 4, and will not shake.

[0031] The technical effect of this utility model is as follows: by using the circumferentially distributed electric push rods 5 and fixing plate 6, the electric push rods 5, which move and extend synchronously, push the fixing plate 6 to fix the cylindrical workpiece placed on the suction cup 1 from all sides. This can achieve the purpose of fixing the cylindrical workpiece and making it concentric with the center of the suction cup 1. In addition, suction cups 1 of different sizes can be fixed by the fixing seat 4 and sliding plate 9.

[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
