[0003] Therefore, there is an urgent need for a clamping fixture and a clamping device that can solve the problem of difficult clamping and the inability to process the outer circumference of a part 360° at one time, thereby improving processing efficiency. Utility Model Content

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] The utility model provides a clamping device, such as Figure 1-Figure 3 As shown, the clamping device includes a base 30 and a clamping fixture, on which a part to be clamped 40 is mounted. However, the clamping fixtures in the prior art are clamped by closely fitting with the shape of the part to be clamped 40, so not only is clamping difficult, but the clamping fixture will interfere with the processing position of the part to be clamped 40 after clamping, resulting in the inability of the processing personnel to use tools, mounting parts, etc. to process the part to be clamped 40 at the corresponding position, thereby failing to achieve the problem of one-time processing of 360° of the outer circumference of the part to be clamped 40.

[0042] The technical solution of the clamping fixture provided by the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0043] like Figure 4 and Figure 5As shown, the clamping fixture includes a first clamp 10 and a second clamp 20, the first clamp 10 is used to clamp the part to be clamped 40, and the second clamp 20 is used to clamp and fix the first clamp 10. Specifically, the first clamp 10 has a first clamping surface 11 and a second clamping surface 12, and a protruding structure 111 is convexly provided on the first clamping surface 11, and the shape and size of the protruding structure 111 respectively match the shape and size of the avoidance structure of the part to be clamped 40, and the protruding structure 111 is connected with the avoidance structure in an embedded manner; the periphery of the part to be clamped 40 is located outside the first clamp 10, so that the first clamp 10 will not interfere with the peripheral processing of the part to be clamped 40; the second clamp 20 is arranged on the supporting surface of the base 30, and is connected to the second clamping surface 12 of the first clamp 10, so that both the first clamp 10 and the part to be clamped 40 are fixed.

[0044] The clamping fixture is provided with a first fixture 10 and a second fixture 20. A protruding structure 111 is provided on the first clamping surface 11 of the first fixture 10 so as to be engaged with the avoidance structure of the part to be clamped 40, thereby fixing the part to be clamped 40 on the first fixture 10. The first fixture 10 is connected to the second fixture 20 through the second clamping surface 12, and the second fixture 20 is provided on the supporting surface, thereby ensuring that the clamping fixture has a stable clamping effect. In addition, since the periphery of the part to be clamped 40 is located outside the first fixture 10, that is, there is a corresponding avoidance space between the edge of the periphery of the first fixture 10 and the periphery of the part to be clamped 40, the processing personnel can perform one-time processing of the periphery of the part to be clamped 40 at 360° in this avoidance space, without changing the clamping angle of the clamping fixture to the part to be clamped 40 during the processing, thereby reducing the processing difficulty and improving the processing efficiency.

[0045] To ensure the clamping effect of the first clamp 10 on the clamped member 40, Figure 4 As shown, a plurality of protrusion structures 111 are provided on the first clamping surface 11, and to ensure uniformity in the hand, the plurality of protrusion structures 111 are arranged at intervals on the first clamping surface 11. In addition, the plurality of protrusion structures 111 are integrally formed with the first clamp 10, which is convenient for processing and production, thereby reducing the overall manufacturing cost.

[0046] To further ensure that the clamped part 40 does not fall off from the first clamp 10, Figure 4 and Figure 5 As shown, a plurality of locking holes 13 are provided on the first clamp 10, and in the thickness direction of the first clamp 10, the locking holes 13 penetrate from the first clamping surface 11 to the second clamping surface 12, and the locking member can pass through the locking holes 13 to connect with the member to be clamped 40. That is, the locking member penetrates from the second clamping surface 12 to the first clamping surface 11 and is connected and fixed with the bottom of the member to be clamped 40. This arrangement is not only simple in structure and convenient in operation, but also does not affect the periphery of the member to be clamped 40, thereby ensuring the convenience of operation of the processing personnel.

[0047] It is worth noting that in this embodiment, the inner wall of the locking hole 13 is provided with a thread, and the locking member is a screw. Screws are relatively common, inexpensive, easy to produce, and it is also very convenient to manufacture threaded holes, which reduces the cost of the overall structure. In other embodiments, the locking member can be a bolt, etc., as long as it is easy to produce and has a good locking effect, and no other restrictions are made in this embodiment.

[0048] To facilitate the connection, Figure 5 and Figure 6 As shown, the second clamping surface 12 is provided with a connecting hole 14, and the second clamp 20 is provided with a clamping structure 21, the clamping structure 21 can clamp the first clamp 10, and the clamping structure 21 can form a detachable connection with the connecting hole 14. By using the clamping structure 21 to form a detachable connection with the connecting hole 14, it is not only convenient for installation, but also convenient for subsequent maintenance and replacement. At the same time, more parts 40 to be clamped can be adapted by replacing the first clamp 10, thereby expanding the scope of use of the clamping fixture. To this end, in order to ensure that the clamping structure 21 does not interfere with the part 40 to be clamped, the connecting hole 14 does not penetrate to the first clamping surface 11 in the thickness direction of the first clamp 10. Therefore, when the clamping structure 21 is connected to the connecting hole 14, it will not pass through the first clamping surface 11 to contact the part 40 to be clamped, thereby ensuring that the part 40 to be clamped will not be damaged. In addition, in this embodiment, in order to ensure the clamping effect, four clamping structures 21 are provided on the second clamp 20, and four connecting holes 14 are also provided accordingly, so as to ensure the stability of the clamping effect. In other embodiments, the number of clamping structures 21 and connecting holes 14 can be adjusted according to actual needs, and is not limited in this embodiment.

[0049] In addition, if Figure 6 As shown, a plurality of mounting holes 22 are also provided on the second clamp 20, and the clamping structure 21 can be provided in any mounting hole 22. Through this structure, the setting position of the clamping structure 21 can be adjusted according to actual needs. When the number of the clamping structures 21 needs to be increased or decreased, the clamping structure 21 can be directly installed or removed at the corresponding position, which is simple and convenient.

[0050] It is worth noting that, in this embodiment, after the clamping structure 21 extends into the connecting hole 14, it can automatically clamp the first clamp 10, thereby further simplifying the operation. It is further noted that, in this embodiment, the clamping structure 21 adopts a zero-point clamp. The zero-point clamp is a conventional structure in the art, which is a clamp that automatically positions and clamps the workpiece at a fixed reference point through a mechanical or pneumatic system. The positioning using the zero-point clamp is accurate and the clamping effect is good.

[0051] When using the clamping device of the fundamental utility model, first fix the second clamp 20 on the supporting surface of the base 30, and connect the clamping structure 21 with the connecting hole 14 so that the second clamp 20 clamps the first clamp 10, and finally, the protruding structure 111 on the first clamp 10 is connected with the avoidance structure of the part to be clamped 40 to form an interlocking connection to fix the part to be clamped 40 so that the outer periphery of the part to be clamped 40 is located outside the first clamp 10, so that the processing personnel can process the outer periphery of the part to be clamped 40 at one time, thereby improving the processing efficiency.

[0052] In summary, the use of the clamping fixture and the clamping device provided by the present invention can not only reduce the difficulty of clamping, but also ensure that the processing personnel can process 360° of the outer circumference of the clamping member 40 in one go.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
