Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing equipment technology, and in particular to a simple clamp for metal processing. Background Technology
[0002] New materials are a key industry for development and the cornerstone of industrial development. In the processing of new materials, especially metal materials, round bars are an important specification for parts processing.
[0003] The machining of round bars mainly employs lathes or CNC equipment. Centering is the key to successful round bar machining. Round materials are easily aligned using a three-jaw chuck, resulting in less material loss during machining. However, square materials, especially rectangular materials, are prone to center deviation when aligned using a three-jaw chuck, leading to excessive material loss, smaller diameter round bars, and higher material consumption. Utility Model Content
[0004] This invention overcomes the shortcomings of the prior art and provides a simple fixture for metal processing.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] This utility model provides a simple fixture for metal processing, the simple fixture comprising a fixture module:
[0007] The clamping module includes a first clamping block, which is made of titanium alloy and is a flat metal block with a semi-circular appearance. The first clamping block is guided and connected to a second clamping block through a limiting rod. The second clamping block is made of the same material and has the same appearance as the first clamping block. The second clamping block can be clamped and operated relative to the first clamping block on a three-jaw chuck with different opening and closing ranges through the limiting rod.
[0008] Furthermore, in a preferred embodiment of the present invention, a plurality of limiting holes are provided on the central axis of the first clamping block, and the limiting holes are used to insert and fix one end of the limiting rod.
[0009] Furthermore, in a preferred embodiment of the present invention, the second clamping block has a plurality of guide through holes, and each guide through hole on the second clamping block is symmetrically distributed with each limiting hole of the first clamping block.
[0010] Furthermore, in a preferred embodiment of this utility model, the difference between the diameter of the guide hole and the diameter of the limiting rod is 1 to 2 mm.
[0011] Furthermore, in a preferred embodiment of the present invention, the guide hole extends through the other end of the limiting rod, allowing the first clamping block to freely extend and retract on the limiting rod.
[0012] Furthermore, in a preferred embodiment of the present invention, all the limiting holes of the first clamping block and all the guide through holes of the second clamping block are arranged laterally linearly along the central axis.
[0013] Furthermore, in a preferred embodiment of the present invention, the opening and closing space between the first clamping block and the second clamping block is used to place and clamp the square metal block.
[0014] Furthermore, in a preferred embodiment of this utility model, the limiting rod can be positioned according to the size specifications of the square metal block.
[0015] Furthermore, in a preferred embodiment of the present invention, the first clamping block and the second clamping block are fixed by a three-jaw chuck.
[0016] The beneficial technical effects of this utility model are as follows:
[0017] This invention uses two identical semi-circular flat metal clamping blocks, a first clamping block and a second clamping block, placed on a three-jaw chuck. When processing is required, the metal block material is placed between the first and second clamping blocks. Under the control of a lathe or CNC machining equipment, the three-jaw chuck is brought together. During the coming together process, the second clamping block is guided to slide on the limit rod of the first clamping block, causing the first and second clamping blocks to move and merge relative to each other. Finally, during the merging process, the metal block material is clamped at the center position of the three-jaw chuck, achieving a center alignment and positioning effect for the metal block material. This avoids the center offset phenomenon that occurs during clamping and positioning with traditional fixtures, effectively prevents over-cutting, and reduces the reprocessing and scrap rate of the block material.

[0030] Example
[0031] like Figure 1-5 As shown, this application provides a simple fixture for metal processing, the simple fixture including a fixture module:
[0032] The clamping module includes a first clamping block 1, which is made of titanium alloy and is a flat metal block with a semi-circular appearance. The first clamping block 1 is guided and connected to a second clamping block 3 through a limiting rod 2. The second clamping block 3 is made of the same material and has the same appearance as the first clamping block 1. The second clamping block 3 can be clamped and operated relative to the first clamping block 1 on a three-jaw chuck 4 with different opening and closing ranges through the limiting rod 2.
[0033] The first clamping block 1 and the second clamping block 3 are fixed by a three-jaw chuck 4.
[0034] It should be noted that before processing, the three-jaw chuck 4 of the existing lathe or CNC equipment is first controlled to be in the open state. The first clamping block 1 is firmly placed on two jaws of the three-jaw chuck 4. Then, the square metal block 7 is placed on the first clamping block 1. The second clamping block 3 is passed through the limiting rod 2. The limiting rod 2 guides the sliding of the second clamping block 3, so that the second clamping block 3 slides down to the opposite side of the square metal block that is in contact with the first clamping block 1, that is, directly above the square metal block 7. At this time, the existing lathe or CNC equipment is started to control the three-jaw chuck 4 to tighten towards the center. Under the tightening drive of the three-jaw chuck 4, the first clamping block 1 and the second clamping block 3 gradually move towards the center at the same time until the square metal block 7 is completely clamped. During the process of the first clamping block 1 and the second clamping block 3 moving towards the center, they will gradually move towards the center position of the three-jaw chuck 4, and finally make the square metal block 7 aligned with the center point of the three-jaw chuck 4. For example, placing a square metal block 7 directly on a three-jaw chuck and cutting its surface yields a cylinder with a diameter of 17mm. However, placing it on this fixture and cutting its surface yields a cylinder with a diameter of 22mm. This demonstrates that this fixture achieves precise material center alignment, thereby reducing material loss during processing, preventing over-cutting due to center misalignment of the square material, saving significant material costs, and substantially reducing rework and scrap rates in the processing of square materials.
[0035] Several limiting holes 5 are provided on the central axis of the first clamping block 1. The limiting holes 5 are used to insert and fix one end of the limiting rod 2.
[0036] It should be noted that the limiting rod is inserted vertically into the limiting hole 5, which in turn constrains the limiting rod 2 to prevent it from shifting or falling off during use. This allows the limiting rod 2 to guide the second clamping block 3 to slide longitudinally, so that the second clamping block 3 is positioned on the three-jaw chuck 4 and closes relative to the first clamping block 1 to clamp the square metal block 7. This achieves precise positioning and effective limiting of the metal clamp structure, which not only improves the convenience and stability of assembly, but also enhances the safety and reliability of the overall metal clamp structure. It is suitable for processing applications that require high precision in center positioning and limiting effect for square materials.
[0037] The second clamping block 3 has several guide holes 6 on its block body, and each guide hole 6 on the second clamping block 3 is symmetrically distributed with each limiting hole 5 of the first clamping block 1.
[0038] The difference between the diameter of the guide hole 6 and the diameter of the limiting rod 2 is 1 to 2 mm.
[0039] The guide hole extends through the other end of the limiting rod, allowing the first clamping block to freely extend and retract on the limiting rod.
[0040] All the limiting holes 5 of the first clamping block 1 and all the guide through holes 6 of the second clamping block 3 are arranged laterally linearly along the central axis.
[0041] It should be noted that a 1-2mm gap is left between the slightly larger guide hole 6 and the limiting rod 2. This effectively prevents jamming or damage caused by excessive tightness during the process of the first clamping block 1 and the second clamping block 3 approaching the center of the three-jaw chuck 4. Secondly, the 1-2mm diameter difference is within a reasonable assembly tolerance range, which can accommodate slight dimensional errors that may occur when the limiting rod 2 clamps the square metal block 7. This ensures effective guidance and support for the limiting rod 2, preventing excessive wobbling and improving the stability and firmness of the clamping process of the square metal block 7. In addition, in environments with large temperature variations during processing, the 1-2mm diameter gap can buffer dimensional changes caused by thermal expansion and contraction, preventing jamming or damage to the guide contraction structure between the first and second clamping blocks. This effectively improves the convenience and service life of the fixture maintenance and enhances the error tolerance of center machining.
[0042] The space between the first clamping block 1 and the second clamping block 3 is used to place and clamp the square metal block 7.
[0043] The limiting rod 2 can be positioned according to the size and specifications of the square metal block 7.
[0044] It should be noted that the opening space between the first clamping block 1 and the second clamping block 3 can accommodate square metal blocks 7 of any size, such as 45×45mm or 70×55mm, improving the adaptability and versatility of the simple metal processing fixture. Simultaneously, the placement of limiting rods 3 around the square metal block 7 effectively guides it to move towards the center position when the three-jaw chuck 4 closes, preventing skewing of the square metal block 7 during the closing process and center positioning offset caused by random placement. This eliminates the need for operators to frequently adjust the clamping position of the square metal block 7, reducing manpower, saving processing time, simplifying the processing flow, reducing center deviation caused by manual intervention, and improving the efficiency and quality of square surface cutting.
[0045] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
