Technical Field
[0001] This utility model relates to the field of workpiece processing technology, and in particular to a clamping device. Background Technology
[0002] When machining a workpiece, it is first necessary to clamp and fix it. Currently, a three-jaw chuck is commonly used for clamping and fixing workpieces. However, a three-jaw chuck can only clamp and fix workpieces of rotation. Some joints include a main body and an extension, which are vertically connected. The three-jaw chuck cannot clamp and fix these parts, making them impossible to machine. Utility Model Content
[0003] The main purpose of this invention is to provide a clamping device that solves the problem that existing clamping devices cannot clamp and fix irregularly shaped workpieces, thus making them impossible to process.
[0004] To address the aforementioned problems, this utility model proposes a clamping device for clamping a connector, comprising:
[0005] Base;
[0006] A clamping member, comprising a first clamping portion and a second clamping portion, wherein one end of each of the first and second clamping portions is connected to the base, and the other end of each extends away from the base; a clamping gap is formed between the first and second clamping portions; and a first mounting groove and a second mounting groove are respectively provided at the other end of the first and second clamping portions, the first and second mounting grooves being used to jointly support an external workpiece; and
[0007] A connector is sequentially connected to the second clamping part and the first clamping part along a direction perpendicular to the clamping gap, so as to secure the external workpiece in the first mounting groove and the second mounting groove.
[0008] In one embodiment, a clearance space is formed between the clamping member and the base.
[0009] In one embodiment, the connector is a screw-in connector, which is sequentially threaded to the second clamping part and the first clamping part.

[0027] When machining a workpiece, it is first necessary to clamp and fix it. Currently, a three-jaw chuck is commonly used for clamping and fixing workpieces. However, a three-jaw chuck can only clamp and fix workpieces of rotation. Some joints include a main body and an extension, which are vertically connected. The three-jaw chuck cannot clamp and fix these parts, making them impossible to machine.
[0028] To address the aforementioned problems, this utility model proposes a clamping device, which aims to solve the problem that existing clamping devices cannot clamp and fix irregularly shaped workpieces, thus preventing their processing.
[0029] like Figure 1 and Figure 2In one embodiment, the clamping device is used to clamp the connector. The clamping device includes a base 10, a clamping member 20, and a connecting member 30. The clamping member 20 includes a first clamping part 21 and a second clamping part 22. One end of the first clamping part 21 and the second clamping part 22 are both connected to the base 10, and the other end of both are extended in a direction away from the base 10. A clamping gap 23 is formed between the first clamping part 21 and the second clamping part 22. The other end of the first clamping part 21 and the second clamping part 22 are respectively provided with a first mounting groove 211 and a second mounting groove 221. The first mounting groove 211 and the second mounting groove 221 are used to jointly support the external workpiece 50. The connecting member 30 is connected to the second clamping part 22 and the first clamping part 21 in sequence along the direction perpendicular to the clamping gap 23, so that the external workpiece 50 is fastened in the first mounting groove 211 and the second mounting groove 221.
[0030] In this embodiment, the base 10 is a cylindrical structure used to provide stable load-bearing capacity for the clamping device. The connection between the base 10 and the clamping member 20 is an integrated design to ensure structural stability. The clamping member 20 includes a first clamping part 21 and a second clamping part 22, and both are respectively provided with a first mounting groove 211 and a second mounting groove 221 to jointly support the workpiece 50. The circumferential shape of the mounting space formed by the combination of the first mounting groove 211 and the second mounting groove 221 is adapted to the bottom shape of the workpiece 50 to ensure that the workpiece 50 can be initially and stably placed in the clamp. In the holder 20, since one end of the first clamping part 21 and the second clamping part 22 are both connected to the base 10, and the other end of both are extended in a direction away from the base 10, the first clamping part 21 and the second clamping part 22 have a certain swinging ability. The connection between the connector 30 and the first clamping part 21 and the second clamping part 22 can be a snap-fit or bolt connection, so that the first clamping part 21 and the second clamping part 22 gradually approach each other until they fit together. At this time, the clamping gap 23 disappears, and the workpiece 50 is then fastened in the first mounting groove 211 and the second mounting groove 221 to complete the clamping and fixing work.
[0031] When clamping, the clamping device proposed in this utility model first places the workpiece 50 in the structure formed by the combination of the first mounting groove 211 and the second mounting groove 221, and then fastens the first clamping part 21 and the second clamping part 22 by the connecting member 30 until there is no clamping gap 23 between the first clamping part 21 and the second clamping part 22. At this time, the workpiece 50 is fixed in the structure formed by the combination of the first mounting groove 211 and the second mounting groove 221, thereby realizing the clamping and fixing of the irregularly shaped workpiece 50.
[0032] like Figure 1 and Figure 2 In one embodiment, a clearance space 40 is formed between the clamping member 20 and the base 10.
[0033] In this embodiment, the clamping member 20 is located in the middle section of the upper surface of the base 10. At the same time, the cross-sectional area of the clamping member 20 is smaller than the cross-sectional area of the base 10. As a result, two clearance spaces 40 are formed on both sides of the clamping member 20 relative to the base 10. The clearance spaces 40 allow the first clamping part 21 and the second clamping part 22 to have sufficient swing space so that they can fit together or separate, thereby improving the clamping convenience of the clamping device.
[0034] like Figure 1 and Figure 2 In one embodiment, the connector 30 is a screw-in connector, which is sequentially threaded to the second clamping part 22 and the first clamping part 21.
[0035] In this embodiment, the connector 30 is a bolt, and the first clamping part 21 and the second clamping part 22 are respectively provided with threaded holes. The connector 30 is threadedly connected to the two. By changing the tightness of the connector 30 relative to the first clamping part 21 and the second clamping part 22, the width of the clamping gap 23 is adjusted, thereby controlling the tightness of the first mounting groove 211 and the second mounting groove 221 on the workpiece 50. This ensures that the workpiece 50 can be tightly clamped by the clamping device while ensuring that the workpiece 50 will not be damaged due to over-clamping, thus improving the practicality of the clamping device.
[0036] like Figure 1 and Figure 2 In one embodiment, the clamping device includes at least two connectors 30, which are spaced apart along the length of the clamping gap 23.
[0037] In this embodiment, the number of connectors 30 is at least two, and they are spaced apart along the length of the clamping gap 23. By using multiple connectors 30, the clamping force can be more evenly distributed on the surface of the workpiece 50, preventing deformation or damage to the workpiece 50 caused by the clamping force being concentrated at a single point. At the same time, multiple connectors 30 provide additional safety; if one connector 30 fails or becomes loose, the other connectors 30 can still maintain the stability of the workpiece 50, preventing it from accidentally falling off or shifting. This redundant design improves the overall safety of the device.
[0038] like Figure 1 and Figure 2 In one embodiment, the initial width of the clamping gap 23 is D, wherein 0.5 mm <D<1.5mm。
[0039] In this embodiment, on the one hand, if the initial width of the clamping gap 23 is too small, it is likely to lead to a weakened fastening effect of the connecting member 30 and increase the installation difficulty of the workpiece 50 at the same time; if the initial width of the clamping gap 23 is too large, it is likely to cause the connecting member 30 to be difficult to clamp the first clamping portion 21 and the second clamping portion 22. Therefore, the initial width of the clamping gap 23 is set to D, where 0.5 mm < D < 1.5 mm, such as 0.7 mm, 1 mm, 1.3 mm, etc.
[0040] Such as Figure 1 and Figure 2 , in an embodiment, the second clamping portion 22 is provided with an avoidance groove 222 along the length direction of the clamping gap 23, and the avoidance groove 222 communicates with the clamping gap 23.
[0041] In this embodiment, the avoidance groove 222 is opened at one end of the second clamping portion 22 close to the base 10 and communicates with the clamping gap 23. The design of this avoidance groove 222 reduces the bottom thickness of the second clamping portion 22, making it more convenient for the second clamping portion 22 to swing. Furthermore, it makes it more convenient for the connecting member 30 to fasten the second clamping portion 22 and the first clamping portion 21, improving the clamping convenience of the clamping device.
[0042] Such as Figure 1 and Figure 2 , in an embodiment, the groove wall of the avoidance groove 222 is arc-shaped.
[0043] In this embodiment, the groove wall of the avoidance groove 222 is arranged in a circular arc shape. This setting method can make the swing of the second clamping portion 22 smoother, and further improve the fastening degree between the second clamping portion 22 and the first clamping portion 21, further enhancing the clamping stability of the clamping device.
[0044] Such as Figure 1 and Figure 2 , in an embodiment, the thickness of the second clamping portion 22 is less than the thickness of the first clamping portion 21.
[0045] In this embodiment, the thickness of the second clamping portion 22 is set to be relatively thin, less than the thickness of the first clamping portion 21. This allows the clamping device to mainly adjust the second clamping portion 22 during the fastening process, with the first clamping portion 21 mainly playing a fixing role. The relatively thin second clamping portion 22 is more likely to complete fine swings. By continuously tightening the connecting member 30, the second clamping portion 22 approaches the first clamping portion 21, thus completing the clamping and fixing of the workpiece 50. This setting method further improves the clamping convenience of the clamping device and increases the working efficiency.
[0046] Such as Figure 1 and Figure 2In one embodiment, one end of the first mounting groove 211 and the second mounting groove 221 on the same side is directly opposite the center of the base 10.
[0047] In this embodiment, the lengths of the first mounting groove 211 and the second mounting groove 221 are half the lengths of the first clamping member 20 and the second clamping member 20. Thus, one end of the first mounting groove 211 and the second mounting groove 221 on the same side is directly opposite the center of the base 10. When the connector is placed in the combined structure formed by the first mounting groove 211 and the second mounting groove 221, the extension of the connector is directly opposite the center of the base 10. This placement method facilitates subsequent processing of the connector, thereby improving the practicality of the clamping device.
[0048] like Figure 1 and Figure 2 In one embodiment, the clamping device is made of steel.
[0049] In this embodiment, the clamping device is made of S136 steel to give it good wear resistance and toughness, so that it can resist wear and friction, and withstand greater impact and vibration, thereby reducing damage during use and extending its service life.
[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
