Description

Technical Field

[0001] This utility model relates to the technical field of magnetic adsorption fixing devices, specifically a parts clamp based on magnetic adsorption. Background Technology

[0002] In the drilling process of ferromagnetic materials such as steel bearing outer rings, traditional mechanical clamping methods such as three-jaw chucks are usually used to fix the parts by applying local pressure. This can easily generate concentrated stress on the surface of thin-walled parts, leading to springback deformation or roundness exceeding the tolerance after machining. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a parts clamping device based on magnetic adsorption, which solves the problem that traditional mechanical clamping can easily cause defects on the surface of thin-walled parts.

[0004] This utility model discloses a parts clamping device based on magnetic adsorption, comprising a processing table, limiting devices, an electromagnet chuck, and a heat dissipation device. The processing table has a heat dissipation groove in the center, and a support ring is fixedly connected to the inner wall of the heat dissipation groove. Support feet are fixedly connected to the four corners of the lower surface of the processing table. At least four limiting devices are provided, and the limiting devices are arranged in a ring on the upper surface of the processing table and close to the heat dissipation groove. The electromagnet chuck is fixedly connected to the upper surface of the support ring, and the heat dissipation device is disposed between the four support feet.

[0005] As a further improvement of this utility model, the limiting device includes a fixed plate and a movable plate. The movable plate is slidably connected to the upper surface of the movable plate. A limiting block is fixedly connected to the side of the movable plate near the center of the processing table. A rubber pad is fixedly connected to the side of the limiting block near the center of the processing table.

[0006] As a further improvement of this utility model, a groove is provided in the center of the upper surface of the fixed plate, and a slider is fixedly connected to the center of the lower surface of the movable plate, the slider being slidably connected inside the groove.

[0007] As a further improvement of this utility model, the two ends of the slide groove pass through the left and right ends of the support plate respectively, the cross-section of the slide groove is T-shaped, the shape and structure of the slider matches the shape and structure of the slide groove, and an anti-slip pad is fixedly connected to the surface of the slider.

[0008] As a further improvement of this utility model, a first bolt is provided at the position near both sides of the slide groove. The first bolt is threadedly connected to the processing table, and a second bolt is threadedly connected to the upper surface of the movable plate and the end away from the limiting block.

[0009] As a further improvement of this utility model, the heat dissipation device includes a support plate and a cooling fan, wherein the cooling fan is fixedly connected to the upper surface of the support plate.

[0010] As a further improvement of this utility model, U-shaped plates are fixedly connected to both sides of the support plate and at the positions corresponding to the support feet. The U-shaped plates are inserted into the surface of the support feet and fixedly connected to the support feet by a third bolt.

[0011] As a further improvement of this utility model, heat dissipation holes are provided on the surface of the support ring.

[0012] As a further improvement of this utility model, the upper surface of the fixing plate is provided with scale lines.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the heat dissipation groove, support ring, and electromagnet chuck set on the processing table, allows the operator to use the electromagnet chuck to adsorb and fix thin-walled steel parts on its surface and keep the parts stable. The limiting device set around the processing table allows the rubber pad on the limiting plate to fit against the surface of the part, which can further limit the position of the part without excessively squeezing the surface of the part, and prevent the danger of the part moving after the electromagnet chuck accidentally loses power. The coordinated design of the electromagnet chuck and the limiting device takes into account both quick clamping and safety.

[0014] 2. This utility model, through the heat dissipation holes set on the support ring and the setting of the cooling fan, can effectively cool down the electromagnet chuck and prevent it from overheating during operation.

[0015] 3. This utility model adjusts the position of the limiting block by sliding the movable plate to adapt to parts of different sizes. The rubber pad avoids hard contact, prevents scratches and deformation of the part surface, and improves the versatility of the fixture. The second bolt set on the movable plate, together with the scale line set on the fixed plate, makes it convenient for the staff to position the position of each movable plate and keep the position of each limiting block synchronized.

[0018] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0019] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] Please see Figure 1-8 This utility model discloses a parts clamping device based on magnetic adsorption, including a processing table 1, a limiting device, an electromagnet chuck 5, and a heat dissipation device. The processing table 1 has a heat dissipation groove 2 in the center, and a support ring 3 is fixedly connected to the inner wall of the heat dissipation groove 2. Support feet 7 are fixedly connected to the four corners of the lower surface of the processing table 1. At least four limiting devices are provided. The limiting devices are arranged in a ring on the upper surface of the processing table 1 and close to the heat dissipation groove 2. The electromagnet chuck 5 is fixedly connected to the upper surface of the support ring 3. The heat dissipation device is arranged between the four support feet 7.

[0023] The limiting device includes a fixed plate 10 and a movable plate 13. The movable plate 13 is slidably connected to the upper surface of the movable plate 13. A limiting block 14 is fixedly connected to the side of the movable plate 13 near the center of the processing table 1. A rubber pad 15 is fixedly connected to the side of the limiting block 14 near the center of the processing table 1.

[0024] When using this device to clamp parts, first place the parts in the center of the electromagnet chuck 5, then slide each movable plate 13 so that the rubber pad 15 on the limiting block 14 is in contact with the surface of the parts. Then, energize the electromagnet chuck 5, and the electromagnet chuck 5 generates magnetic force to firmly attract the parts. The limiting block 14 further limits the position of the parts.

[0025] In some other embodiments, a groove 11 is provided in the center of the upper surface of the fixed plate 10, and a slider 16 is fixedly connected to the center of the lower surface of the movable plate 13. The slider 16 is slidably connected inside the groove 11. The upper surface of the fixed plate 10 is provided with scale lines. The two ends of the groove 11 pass through the left and right ends of the support plate 6 respectively. The cross-section of the groove 11 is T-shaped. The shape and structure of the slider 16 match the shape and structure of the groove 11. An anti-slip pad 17 is fixedly connected to the surface of the slider 16.

[0026] The T-shaped groove 11 cooperates with the slider 16 to guide the movable plate 13 to move in a straight line. The T-shaped structure design can prevent the slider 16 from falling out and also facilitates the docking of the movable plate 13 with the fixed plate 10, thereby enhancing the reliability of the limiting device. The anti-slip pad 17 increases the friction between the slider 16 and the groove 11, preventing the movable plate 13 from sliding accidentally during processing, ensuring clamping stability, reducing the impact of vibration on the limiting accuracy, and improving processing quality.

[0027] In this embodiment, a first bolt 12 is provided at both sides of the slide 11. The first bolt 12 is threadedly connected to the processing table 1. A second bolt 18 is threadedly connected to the upper surface of the movable plate 13 and the end away from the limiting block 14.

[0028] The fixed plate 10 is fixed to the processing table 1 by the first bolt 12. The threaded connection makes it easy to disassemble and assemble the fixed plate 10. The second bolt 18 is used to lock the position of the movable plate 13 to ensure that the movable plate 13 remains stable during operation.

[0029] The heat dissipation device includes a support plate 6 and a cooling fan 8. The cooling fan 8 is fixedly connected to the upper surface of the support plate 6. The surface of the support ring 3 is provided with heat dissipation holes 4. U-shaped plates 9 are fixedly connected to the left and right sides of the support plate 6 and to the corresponding positions of the support feet 7. The U-shaped plates 9 are inserted into the surface of the support feet 7 and fixedly connected to the support feet 7 by a third bolt.

[0030] The heat dissipation device can prevent the electromagnet from overheating and causing magnetic force attenuation, extend its service life, improve the temperature environment of the processing area, and ensure processing accuracy. The heat dissipation holes 4 on the support ring 3 allow air to pass through, further improving the heat dissipation effect.

[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
