Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical casting processing, in particular to a novel rail clamping device with high adjustability and a wider application range. Background Art

[0002] In the field of metallurgical casting processing, an electromagnetic stirrer is used to stir molten aluminum. The operation is convenient, the stirring is sufficient, and the aluminum solution is not polluted during the stirring process. This is a necessary process measure in the aluminum melting and casting industry. The bearing device of the electromagnetic stirrer is a trolley. During the operation of the electromagnetic stirrer, a reaction force will be generated on the trolley, causing the trolley to move back and forth on the track, thereby affecting the effect of the electromagnetic stirrer.

[0003] To prevent the movement of the trolley and fix it in the working position, a hydraulic rail clamping device or an electromagnetic rail clamp is often used to fix the trolley. Both of these structures require an external power source or an external power supply, and the structure is relatively complex, and the production cost is high. Therefore, it is necessary to design a novel rail clamping device with high adjustability and a wider application range to solve the above problems.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] The technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] See Figure 1 and Figure 2 , the present utility model provides a novel rail clamping device with high adjustability and a wider range of use, including:

[0027] a push rod 1, an adjusting nut 2, a contact 3, a return spring 4, a thimble 5, a box body 6, a clamping arm 7, a nut 8, and a clamping spring 9;

[0028] The push rod 1 is connected to the contact 3 through the adjusting nut 2. The return spring 4 is fixedly installed on the box body 6. The thimble 5 is fixedly connected to the return spring 4. The thimble 5 is vertically slidably installed on the box body 6. The clamping arm 7 is rotatably installed on the box body 6. The nut 8 is threadedly installed on the clamping arm 7. The clamping spring 9 is installed between the nut 8 and the clamping arm 7.

[0029] It should be noted that by setting the nut 8, the magnitude of the clamping force can be adjusted. By setting the adjusting nut 2, the extension length of the contact 3 can be adjusted, so as to achieve the purpose of adjusting the degree of outward opening of the clamping arm 7.

[0030] Specifically, a trolley bracket 10 is fixedly arranged on the push rod 1. A trolley base 11 is fixedly arranged on the box body 6. A track 12 is arranged below the trolley base 11. The trolley base 11 moves on the track 12. It should be noted that when the trolley bracket 10 rises and falls, it will drive the push rod 1 to move.

[0031] Specifically, a lift is installed between the trolley base 11 and the trolley bracket 10. It should be noted that the lift is a link lift, which is prior art and will not be elaborated here.

[0032] Specifically, the clamping arm 7 is in contact with the thimble 5. It should be noted that when the thimble 5 moves downward, the downward movement of the thimble 5 drives the clamping arm 7 to open outward.

[0033] Specifically, the track 12 abuts against the clamping arm 7. It should be noted that the trolley is fixed on the track 12.

[0034] Working principle:

[0035] Install the rail clamping device on the trolley. When the trolley support 10 starts to rise, the ejector rod 1 fixed on the trolley support 10 drives the contact 3 to move upward, away from the ejector pin 5 of the rail clamping device. Under the action of the return spring 4, the ejector pin 5 moves upward, away from the clamping arm 7. Under the action of the clamping spring 9, the two clamping arms 7 clamp the track 12, realizing the fixation of the trolley on the track 12. Rotating the nuts 8 on both sides can adjust the magnitude of the clamping force.

[0036] When the trolley support 10 descends, the ejector rod 1 fixed on the trolley support 10 drives the contact 3 to move downward, pressing the ejector pin 5 of the rail clamping device. The downward movement of the ejector pin 5 drives the clamping arm 7 to open outward, releasing the fixed state of the trolley. Rotating the adjusting nut 2 can adjust the extension length of the contact 3, thereby achieving the purpose of adjusting the degree of outward opening of the clamping arm 7.

[0037] The above has introduced in detail a new type of rail clamping device with high adjustability and a wider range of applications provided by the present utility model. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
