Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing, and more specifically, to a jaw mechanism for clamping irregular block-shaped alloys on a vertical drilling machine. Background Technology
[0002] Stainless steel metallurgy requires a large amount of alloys. According to GB / T4010-2015, the sampling and preparation of samples for chemical analysis of ferroalloys, drilling points are randomly selected on the cross-section of the sample block for difficult-to-break alloys to obtain samples for chemical analysis. Vertical drilling machines are generally used to drill samples of difficult-to-break alloys for chemical analysis, such as pig iron blocks, ferronickel blocks, and micro-carbon ferrochrome blocks. Existing vertical drilling machines are equipped with flat-jaw pliers, which have high precision, but due to their shallow jaws, they cannot effectively hold irregular alloy blocks, pig iron blocks, and other blocky alloys. After the alloy block is subjected to drilling force, there is a risk of it flying out or slipping, making sampling impossible. The flying alloy block poses a significant safety hazard. During drilling, there are also problems such as drill bit breakage due to sample block shaking, and excessive drill bit consumption. Utility Model Content

[0005] This application provides a jaw mechanism for clamping irregular blocky alloys on a vertical drilling machine. The jaw mechanism includes a jaw body and a clamping assembly. The jaw body includes a fixed jaw and a movable jaw. The clamping assembly has two parts, which are respectively disposed on the fixed jaw and the movable jaw. The clamping assembly includes a clamping plate and a fixed plate. The clamping plate and the fixed plate are fixedly connected. The fixed plate is also fixedly connected to the fixed jaw or the movable jaw. The two clamping plates form a clamping opening with a smaller upper opening and a larger lower opening.
[0006] Furthermore, in this utility model, both the fixing plate and the clamping plate are integrally formed.
[0007] Furthermore, in this utility model, both the fixing plate and the clamping plate are L-shaped plates.
[0008] Furthermore, in this utility model, the horizontal surface of the fixing plate and the horizontal surface of the clamping plate are fixedly connected by the first bolt.
[0009] Furthermore, in this utility model, the vertical surface of the fixing plate is provided with a connecting hole, and a second bolt is inserted through the connecting hole to fix the fixing plate to the fixed jaw or the movable jaw.
[0010] Furthermore, in this utility model, the vertical surfaces of the two clamping plates are both bent inwards and arranged in a figure-eight shape.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] Example 1
[0022] This embodiment provides a jaw mechanism for clamping irregularly shaped blocky alloys on a vertical drilling machine, such as... Figure 1 and Figure 2 As shown, it includes a jaw body and a clamping assembly. The jaw body includes a fixed jaw 1 and a movable jaw 2. There are two clamping assemblies, which are respectively located on the fixed jaw 1 and the movable jaw 2. The clamping assembly includes a clamping plate 3 and a fixed plate 4. The clamping plate 3 and the fixed plate 4 are fixedly connected. The fixed plate 4 is also fixedly connected to the fixed jaw 1 or the movable jaw 2. The two clamping plates 3 form a clamping opening with a smaller upper opening and a larger lower opening.
[0023] In this embodiment, both the fixing plate 4 and the clamping plate 3 are integrally molded structures. Integral molded structures have good consistency, high structural strength, and can stably clamp items.
[0024] In one embodiment of this example, such as Figure 2 As shown, both the fixing plate 4 and the clamping plate 3 are L-shaped plates. Depending on the actual needs, the fixing plate 4 and the clamping plate 3 can be spliced together using two angle steels (L-shaped) of suitable size, thickness and angle. They are made using existing materials, are easy to install and have strong reliability.
[0025] Specifically, the horizontal surface of the fixing plate 4 and the horizontal surface of the clamping plate 3 are fixedly connected by the first bolt 5. Further, the vertical surface of the fixing plate 4 is provided with a connecting hole 6, and a second bolt 7 passes through the connecting hole 6 to fix the fixing plate 4 to the fixed jaw 1 or the movable jaw 2.
[0026] In the above embodiments, such as Figure 1 As shown, the vertical surfaces of both clamping plates 3 are bent inwards in a figure-eight shape. Furthermore, the angle between the vertical surface of the clamping plate 3 and the horizontal surface is between 75° and 85°. This figure-eight arrangement results in a jaw opening that is smaller at the top and larger at the bottom, causing the combined force to be downwards after clamping, thus better clamping irregular objects. This firmly holds and fixes the irregular alloy block, facilitating the extraction of samples for alloy chemical analysis. The angle of 75° to 85° provides a secure clamping effect without being too large to damage the object or too small to achieve a firm grip.
[0027] It should be noted that the distance (opening) between the two clamping plates 3 is relatively large, and the opening of the clamping assembly is smaller at the top and larger at the bottom, which provides good containment. After removing the original jaw guard and replacing it with the new clamping assembly, and adjusting the original movable jaw 2, the clamping assembly will clamp the object securely.
[0028] In summary, the embodiments of this utility model provide a jaw mechanism for clamping irregularly shaped block alloys on a vertical drilling machine, which has at least the following advantages or beneficial effects:
[0029] This invention improves the clamping capacity of the jaws by incorporating a clamping assembly, resulting in a more secure grip with downward force after clamping. It is easy to install on-site, highly reliable, and solves the problem of unstable clamping of irregularly shaped, oversized alloys in the original design, thus avoiding safety risks such as objects flying off the jaws or drill bits breaking under stress.
[0030] The above are merely preferred embodiments of this utility model and are 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, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
