Description

Technical Field

[0001] The utility model relates to the technical field of shearing devices, in particular to a shearing device capable of quickly replacing jaws. Background Art

[0002] Crushing scissors and crushing pliers are generally collectively referred to as shearing devices. The working principles of such devices are basically the same, and they use a driving cylinder to drive to complete the cutting or crushing action. The driving cylinder generally uses a hydraulic cylinder. The hydraulic crushing pliers are composed of a pliers body (or a shearing part), a hydraulic cylinder, a movable jaw and a fixed jaw. The external hydraulic system provides oil pressure for the hydraulic cylinder, so that the movable jaw and the fixed jaw of the hydraulic crushing pliers open and close, achieving the effect of crushing or shearing an object.

[0003] The current shearing device is relatively complex to operate when replacing jaws, and tools need to be carried to complete the replacement. Tools are required to first remove the external part fixing the shaft body, loosen and remove the shaft with tools, and then perform jaw replacement operations on other parts. The convenience during jaw replacement is poor, and the speed of the entire jaw replacement process is also relatively slow, which needs to be improved.

[0004] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of seeking excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, a shearing device capable of quickly replacing jaws is provided to solve the problems that the current shearing device is not convenient enough and has a relatively slow speed when replacing jaws. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a shearing device capable of quickly replacing jaws to solve the problems that the current shearing device is not convenient enough and has a relatively slow speed when replacing jaws.

[0006] The technical solution of the utility model is realized as follows:

[0007] The shearing device capable of quickly replacing jaws includes a shearing assembly, a mounting main body and a driving cylinder. A first connecting shaft, a second connecting shaft and a first connecting jaw are sequentially arranged on the shearing assembly. A second connecting jaw, a third connecting jaw and a connecting hole are arranged on the mounting main body. The first connecting shaft is matched with the second connecting jaw, the second connecting shaft is matched with the third connecting jaw. Flat sections are arranged at both ends of the second connecting shaft. Both sides of one end of the driving cylinder are inserted into the connecting holes by plugs. A third connecting shaft is connected to the other end of the driving cylinder. The third connecting shaft is matched with the first connecting jaw. Flat sections are arranged at both ends of the third connecting shaft;

[0008] A limiting member for limiting the first connecting shaft is arranged outside the shearing assembly, and a limiting wrench for limiting the third connecting shaft is arranged on the mounting main body.

[0009] As a preferred embodiment, the shearing assembly includes a first shearing part, a second shearing part and a shearing tool connecting part. The first shearing part and the shearing assembly are hinged by the shearing tool connecting part, and a second connecting shaft is arranged on the shearing tool connecting part.

[0010] As a preferred embodiment, two limiting blocks are arranged on the mounting main body, and the two limiting blocks cooperate to limit the limiting piece.

[0011] Two parallel wrench limiting blocks are arranged on the shearing assembly, and the two wrench limiting blocks cooperate to limit the limiting wrench.

[0012] Hexagonal hole positions are arranged on both the limiting wrench and the limiting block. Hexagonal fastening bolts are arranged at the outer ends of the first connecting shaft and the third connecting shaft. Usually, the positions of the limiting wrench and the limiting block are fixed, and the hexagonal hole positions play a fastening role for the shaft to limit it. When the jaw needs to be replaced, the limiting wrench with a hexagonal hole position can be used as an operating tool to remove the hexagonal fastening bolts.

[0013] As a preferred embodiment, a first crushing part is connected to the first shearing part, and a second crushing part cooperating with the first crushing part is arranged on the second shearing part.

[0014] The crushing part plays a role of crushing, that is, a crushing pliers. With the crushing part, it can be used to effectively crush the clamped object to be crushed to achieve the crushing purpose.

[0015] As a preferred embodiment, the first crushing part includes two rows of parallel crushing teeth, and the second crushing part includes two rows of crushing teeth cooperating with the first crushing part.

[0016] The double-row crushing teeth can more stably clamp the object to be crushed.

[0017] As a preferred embodiment, the first crushing part and the second crushing part are respectively arranged at the outer side positions of the first shearing part and the second shearing part, and the shearing edges are exposed at the inner side positions of the first shearing part and the second shearing part.

[0018] The structure with the crushing part on the outside and the shearing part on the inside can crush the clamping main body for a long time and shear the part to be sheared. For example, when demolishing a building, first use the crushing part as a crushing pliers to crush the outside of the construction waste to expose the internal steel structure, and then use the internal shearing part to cut it.

[0019] In the solution of the present utility model, the fastening of the shaft is realized by using the limiting piece and the limiting wrench. The limiting piece and the limiting wrench can be directly taken out. After being taken out, the limiting wrench can be directly used as a tool to loosen each shaft to achieve quick jaw replacement.

[0020] In the above-mentioned jaw replacement process, the step of using tools to remove the fasteners of the shaft is omitted. The time taken for the direct removal method is shorter, and it comes with its own tools for the next loosening operation, eliminating the need to find tools on-site for operation and being unrestricted by tools. This saves time and is very convenient for jaw replacement, solving the problem that the current jaw replacement of the shearing device is not convenient enough and the speed is slow.

[0021] In addition, the current crushing scissors or crushing pliers have a single function and cannot meet the requirements of comprehensive construction under various working conditions during use, and need to be replaced according to the usage requirements. Therefore, the problem of the single function of the current shearing device also needs to be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0037] In the description of the embodiments, unless otherwise clearly specified and limited, terms such as "set", "connected", etc. shall 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 directly connected, or connected through an intermediate medium, or the internal communication of 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.

[0038] Embodiment 1, as Figures 1 to 7As shown in the figure, a shearing device with a quickly replaceable jaw includes a shearing assembly 2, a mounting body 7 and a driving cylinder 8. On the shearing assembly 2, a first connecting shaft 11, a second connecting shaft 12 and a first connecting jaw 14 are sequentially arranged. On the mounting body, a second connecting jaw 16, a third connecting jaw 17 and a connecting hole position 18 are arranged. The first connecting shaft 11 is matched with the second connecting jaw 16, the second connecting shaft 12 is matched with the third connecting jaw 17. Flat sections 13 are arranged at both ends of the second connecting shaft 12. On both sides at one end of the driving cylinder 8, they are inserted into the connecting hole position 18 by means of plug-ins. At the other end of the driving cylinder 8, a third connecting shaft 15 is connected. The third connecting shaft 15 is matched with the first connecting jaw 14. Flat sections 13 are arranged at both ends of the third connecting shaft 15;

[0039] A limiting member 6 for limiting the first connecting shaft 11 is arranged on the outside of the shearing assembly 2. A limiting wrench 9 for limiting the third connecting shaft 15 is arranged on the mounting body 7.

[0040] The shearing assembly 2 includes a first shearing part 1, a second shearing part 3 and a shearing knife connecting part 4. The first shearing part 1 and the shearing assembly 2 are hinged by means of the shearing knife connecting part 4. The second connecting shaft 12 is arranged on the shearing knife connecting part 4.

[0041] Two limiting blocks 5 are arranged on the mounting body 7. The two limiting blocks 5 cooperate to limit the limiting member 6;

[0042] Two wrench limiting blocks 10 parallel to each other are arranged on the shearing assembly 2. The two wrench limiting blocks 10 cooperate to limit the limiting wrench 9.

[0043] Hexagonal hole positions 19 are arranged on both the limiting wrench 9 and the limiting block 5. Hexagonal fastening bolts are arranged at the outer ends of the first connecting shaft 11 and the third connecting shaft 15. Usually, the positions of the limiting wrench 9 and the limiting block 5 are fixed. The hexagonal hole positions 19 play a role in fastening the shaft and limiting it. When it is necessary to replace the jaw, the limiting wrench 9 with the hexagonal hole position 19 can be used as an operating tool to remove the hexagonal fastening bolts.

[0044] Among them, Figure 2 What is shown is Figure 1 The state of removing the limiting member and the limiting wrench.

[0045] In the solution of the present utility model, the fastening of the shaft is realized by using the limiting member 6 and the limiting wrench 9. The limiting member 6 and the limiting wrench 9 can be directly taken out. After the limiting wrench 9 is taken out, it can be directly used as a tool to loosen each shaft to realize quick jaw replacement.

[0046] In the above-mentioned jaw replacement process, the step of using tools to remove the fasteners of the shaft is omitted. The time taken for the direct removal method is shorter, and it comes with its own tools for the next loosening operation. There is no need to find tools on-site for operation, and it is not restricted by tools. Jaw replacement saves time and is very convenient, solving the problem that the current jaw replacement of the shearing device is not convenient enough and the speed is slow.

[0047] Embodiment 2, refer to Figures 8 - 10 , the difference between this embodiment and Embodiment 1 is that:

[0048] A first crushing part 20 is connected to the first shearing part 1, and a second crushing part 22 that cooperates with the first crushing part 20 is arranged on the second shearing part 3.

[0049] The crushing part plays a role in crushing, that is, a crushing pliers. With the crushing part, it can be used to effectively crush the clamped object to be crushed and achieve the crushing purpose.

[0050] The first crushing part 20 includes two rows of crushing teeth arranged in parallel, and the second crushing part 22 includes two rows of crushing teeth that cooperate with the first crushing part 20.

[0051] The double-row crushing teeth can more stably hold and crush the object to be crushed.

[0052] The first crushing part 20 and the second crushing part are respectively arranged at the outer positions of the first shearing part 1 and the second shearing part 3, and the shearing edges 21 are exposed at the inner positions of the first shearing part 1 and the second shearing part 3.

[0053] The structure with the crushing part on the outside and the shearing part on the inside can shear the part that needs to be cut after crushing the clamped object. For example, when demolishing a building, first use the crushing part as a crushing pliers to crush the outside of the construction waste and expose the internal steel bar structure, and then use the internal shearing part to cut it.

[0054] Embodiment 2 actually installs the crushing shear of Embodiment 1 into a crushing pliers, but essentially they are all realized through the shearing action.

[0055] Currently, the functions of crushing shears or crushing pliers are single, and the simple shearing function or crushing function can no longer meet the needs of comprehensive construction under various working conditions. However, directly replacing the attachments requires a lifting device or a handling device, with complex operations and time-consuming. The utility model can realize the conversion of different functions by quickly replacing the jaw shear devices with different functions, without the need to rely on complex lifting equipment and handling devices, which is convenient and fast, enriches the use functions, and can meet the needs of comprehensive construction under various working conditions. Therefore, this solution not only solves the problem of inconvenient jaw replacement, but also solves the technical problem that the current shearing function is single and cannot meet the needs of comprehensive construction under various working conditions.

[0056] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement; when the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
