CNC machining is widely used in mechanical manufacturing, aerospace, automobiles and other fields, and is an important processing method in modern manufacturing. Common CNC machining equipment includes CNC lathes, CNC milling machines, CNC grinders, etc.
[0003] In the existing technology, CNC centers use fixtures during processing. However, when using them, since fixtures are usually designed to fix objects of specific shapes, when it is necessary to clamp circular objects, the fixture may not be able to provide a suitable fixing position due to its special shape. This may cause the fixture to be unable to clamp the circular object, or the fixation is not firm, affecting the processing quality. For example, when it is necessary to clamp circular objects, a customized fixture may be required, resulting in additional costs and time, and it may not be suitable for objects of other shapes, limiting the versatility of the fixture. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings in the prior art and provide a multifunctional clamp for a numerical control machining center.

[0008] As a preferred embodiment, one end of the circular ring clamp is fixedly connected to one side of triangle plate one, one side of triangle plate one is in contact with one side of triangle plate two, and one side of triangle plate two is fixedly connected to one end of the spring sheet.
[0009] As a preferred implementation, one side of the second triangular plate is fixedly connected to one end of a fixing rod, and the top of the other end of the fixing rod is vertically clamped to the bottom end of the limiting arm.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1
[0025] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: a multifunctional clamp for a CNC machining center, comprising: a clamping mechanism 1, a reset mechanism 2 is arranged inside the clamping mechanism 1, the clamping mechanism 1 comprises a bottom plate 11, a flat clamp 12 is arranged on the top of the bottom plate 11, a connecting rod 13 is arranged inside the flat clamp 12, a circular clamp 14 is arranged at the bottom end of the connecting rod 13, a triangle plate 15 is arranged at one end of the circular clamp 14, a triangle plate 16 is arranged on one side of the triangle plate 15, a spring piece 17 is arranged on one side of the triangle plate 16, a fixing rod 18 is arranged on one side of the triangle plate 16, a limiting arm 19 is arranged on the top of the fixing rod 18, an inclined plate 111 is arranged on one side of the flat clamp 12, a cylinder 110 is arranged on one side of the inclined plate 111, the top of the bottom plate 11 is slidably connected to the bottom of the flat clamp 12, and a sliding plate is provided on the inner wall of the flat clamp 12 Groove 112, the inner surface of the slide groove 112 is slidably connected to one end of the bottom of the circular ring clamp 14, one end of the circular ring clamp 14 is fixedly connected to one side of the triangle plate 15, one side of the triangle plate 15 is in contact with one side of the triangle plate 2 16, one side of the triangle plate 2 16 is fixedly connected to one end of the spring 17, one side of the triangle plate 2 16 is fixedly connected to one end of the fixing rod 18, the other end of the fixing rod 18 is vertically clamped with the bottom end of the limiting arm 19, the top of one side of the bottom plate 11 is movably connected to the outer side of the cylinder 110, one end of the cylinder 110 is movably connected to one side of the inclined plate 111, the top of the inclined plate 111 is in contact with one side of the flat plate clamp 12, the bottom end of the inclined plate 111 is movably connected to the inner wall of the bottom plate 11, the middle end of the circular ring clamp 14 is movably connected to the bottom end of the connecting rod 13, and the top of the connecting rod 13 is connected through the inside of the flat plate clamp 12.
[0026] In this embodiment, when a worker needs to clamp a plate object during use, the plate object is placed between the flat plate clamp 12 and one side of the bottom plate 11. Then, the cylinder 110 is extended so that the inclined plate 111 is subjected to an external force, and its top end is tilted, which affects the flat plate clamp 12, causing it to move from its original position and gradually approach the object until the object is clamped and fixed.
[0027] Secondly, if it is necessary to clamp relatively round objects, such as round tubes, external force can be applied to the connecting rod 13 through manual operation, so that its bottom end is against the middle end of the circular ring clamp 14, and as the external force is continuously applied, the triangle plate 15 on the circular ring clamp 14 will contact the triangle plate 2 16, and during the contact process, pressure will be applied to the triangle plate 2 16, and under the action of the spring 17, it will shrink until the triangle plate 15 passes over the triangle plate 2 16, at which time the circular ring clamp 14 will naturally leak out of the flat clamp 12, thereby clamping and fixing the round tube. This clamping method only requires the application of external force to complete the clamping process, and the operation is relatively simple. There is no complicated mechanical structure or adjustment process, which reduces the complexity and time cost of the operation;
[0028] Both clamping methods are based on applying external force for clamping. The appropriate clamping method can be selected according to specific needs and object types. The operation is relatively simple and there is no complicated mechanical structure or adjustment process, which reduces the complexity and time cost of the operation. Therefore, this clamping method has a certain versatility and can be used to clamp different types of objects. Workers can choose the appropriate method to clamp according to their needs to achieve the purpose of fixing the object.
[0029] Example 2
[0030] like Figure 1 - Figure 4 As shown, the reset mechanism 2 includes a long rod 21, one end of the long rod 21 is fixedly connected to the inside of the base plate 11, one side of the inside of the base plate 11 is fixedly connected to one end of a spring 22, the other end of the spring 22 is fixedly connected to the bottom side of the flat plate clamp 12, and the outer side of the spring 22 is in contact with the outer side of the long rod 21.
[0031] In this embodiment, when the inclined plate 111 does not apply external force to the flat plate clamp 12, in order to enable it to return to its original position, a long rod 21 is designed at the bottom of the flat plate clamp 12, and the long rod 21 can prevent the flat plate clamp 12 from deviating from the path during its movement, and a spring 22 is designed on the long rod 21, one end of the spring 22 is connected to the bottom of the flat plate clamp 12, so when the external force disappears, the spring 22 uses its own retractability to reset the flat plate clamp 12, and the staff does not need to consider how to restore it to the correct position, which reduces the difficulty of operation and improves work efficiency.
[0032] Working principle:
[0033] like Figure 1 - Figure 4As shown, when the utility model is used, according to the needs of the user, it is placed between the flat clamp 12 and one side of the bottom plate 11, and then, the cylinder 110 is extended so that the inclined plate 111 is subjected to an external force, and its top end is tilted, and affects the flat clamp 12, so that it moves in its original position and gradually approaches the object until the object is clamped and fixed. If it is necessary to clamp a relatively round object, such as a round tube, an external force can be applied to the connecting rod 13 through manual operation, so that its bottom end is against the middle end of the circular clamp 14, and as the external force is continuously applied, the triangle plate 15 on the circular clamp 14 will contact the triangle plate 2 16, and during the contact process, pressure will be applied to the triangle plate 2 16, and under the action of the spring piece 17, it will shrink until the triangle plate 15 passes over the triangle plate 2 16, and at this time, the circular clamp 14 naturally leaks out of the flat clamp 12, so as to clamp and fix the round tube object;
[0034] When the inclined plate 111 does not apply external force to the flat plate clamp 12, in order to enable it to return to its original position, a spring 22 is designed on the long rod 21, and one end of the spring 22 is connected to the bottom of the flat plate clamp 12. Therefore, when the external force disappears, the spring 22 uses its own retraction to reset the flat plate clamp 12.
