Description

Technical Field

[0001] This utility model relates to the field of clamp technology, specifically to a special clamp for metal detection. Background Technology

[0002] In metal detection and related precision operations, fixtures serve as crucial auxiliary equipment, playing a vital role in the positioning, fixation, and stability of workpieces. Especially in high-precision detection scenarios, fixtures must possess high adaptability, high reliability, and ease of operation to ensure workpiece stability and operational efficiency during the detection process. While traditional fixtures can achieve basic fixation functions, they have certain limitations in practical use, such as complex structure, cumbersome installation, and insufficient workpiece adaptability.

[0003] Most clamps on the market currently use a single threaded connection or mechanical clamping to fix workpieces. This type of design is easily affected by vibration or workpiece size deviation during use, resulting in unstable workpiece clamping effect. In addition, for scenarios that require frequent workpiece changes, the threaded connection requires complex rotation and docking, which is difficult to adjust and reduces operating efficiency.

[0004] Furthermore, in complex environments, fixtures often need to be installed on slides or other equipment, which places higher demands on the fixture's shock resistance and stability. After installation, traditional fixtures are easily affected by external vibrations due to their large contact area with slides or supporting components, which can lead to displacement or loosening of the workpiece. In metal detection scenarios, the use of precision equipment places extremely high demands on the position of the workpiece, and any slight deviation can significantly affect the detection results.

[0005] In view of the above, this utility model provides a special metal detection clamp. The device is designed with automatic positioning, stable clamping and shock resistance, and can maintain high stability in complex environments, providing more reliable technical support for metal detection operations.

[0041] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0042] In the description of this utility model, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "upper", "lower", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "end", "head", "tail", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] This application proposes a special clamp for metal detection, as detailed below:

[0044] For reference Figure 1-2 This application mainly consists of a support base 1, a connecting top shaft 2 detachably mounted on the support base 1 by bolts, a V-shaped groove 3 and a trapezoidal groove 4 formed on the support base 1 and the connecting top shaft 2, a threaded shaft 5 with a threaded connection set on the connecting top shaft 2, and a positioning component 6 fixed by snapping together through the two threaded shafts 5. This fixture design achieves multiple advantages such as high stability, high adaptability, convenient operation and strong clamping force, and is particularly suitable for metal detection scenarios that require high-precision clamping.

[0045] For reference Figure 1-4 Both the support base 1 and the connecting top shaft 2 are I-shaped, which improves the load-bearing capacity and resistance to deformation, and adapts to the metal detection needs in complex environments. The height of the support base 1 and the connecting top shaft 2 is not limited, and can be adapted to the required support height after connection.

[0046] For reference Figure 1-4 The support base 1 and the connecting top shaft 2 have roughly the same structure, except that the support base 1 has an additional structure for connecting to the external slide rail. Both the support base 1 and the connecting top shaft 2 are provided with a V-shaped groove 3 and a trapezoidal groove 4, and in the two structures, the V-shaped groove 3 and the trapezoidal groove 4 are located on symmetrical sides.

[0047] The V-shaped groove 3 on the support base 1 can disperse pressure and improve stability when the fixture is working. The trapezoidal groove 4 on the support base 1 can reduce the contact area between the support base 1 and the external slide. The support base 1 with the trapezoidal groove 4 has a square shaft 11 protruding outward on one side. There are two square shafts 11. The two square shafts 11 make the support base 1 and the external slide form a connection relationship. The connection distance between the two square shafts 11 is greater than that of the trapezoidal groove 4. Therefore, the bottom surface of the support base 1 on both sides of the trapezoidal groove 4 will press against the external slide. At this time, the design of the trapezoidal groove 4 makes a gap form between them, reducing the contact area with the external slide. This can reduce the vibration transmitted from the external slide to the fixture, and further improve the stability of the fixture when it is working.

[0048] Furthermore, after adjusting the position of the external slide, the support base 1 is securely connected to the external slide by clamping screws 12 provided on the corresponding square shaft 11 on the support base 1, which is not easy to loosen and increases the stability of the overall structure.

[0049] For reference Figure 4 In the connecting top shaft 2, the V-groove 3 design automatically guides the workpiece to the center position of the groove bottom, suitable for clamping round or polygonal workpieces, such as round bars, tubular or conical metal parts, ensuring accurate positioning; at the same time, the inclined surface of the V-groove provides lateral constraint, which can effectively prevent the workpiece from sliding laterally in the fixture; the trapezoidal groove 4 set in the connecting top shaft 2 is set vertically and vertically corresponding to the V-groove 3 on the support base 1, wherein the diameter of the trapezoidal groove 4 is larger than that of the V-groove 3, so that the downward force-applying surface of the connecting top shaft 2 is entirely supported on the upper surface of the support base 1; this helps to increase the stability of the connection. Secondly, the connection between the connecting top shaft 2 and the support base 1 is fixed by four long screws, which pass through the upper surface of the connecting top shaft 2 and connect to the support base 1.

[0050] For reference Figure 1 , Figure 2 and Figure 5-6 The workpiece is placed in the V-groove 3 of the connecting top shaft 2 and then passes through. The upper side is fixed by the cooperation between the threaded shaft 5 and the positioning part 6, which can firmly fix the workpiece for subsequent detection work.

[0051] The threaded shaft 5 includes a threaded rod 51 and a screw top 52. The threaded rod 51 is detachably threaded to the connecting top shaft 2, and the screw top 52 is fixedly connected to the end of the threaded rod 51 away from the end connected to the connecting top shaft 2. In use, the threaded rod 51 can be adjusted up and down to a suitable position first. Then, one side of the threaded rod 51 is engaged with the positioning piece 6, and by rotating the positioning piece 6, the other end of the positioning piece 6 is engaged with the threaded rod 51 on the symmetrical side. At this time, the workpiece is located in the V-groove 3 of the positioning piece 6 and the connecting top shaft 2. The positioning piece 6 can be fastened to the upper end of the workpiece by adjusting the threaded rod 51 downwards again.

[0052] To achieve the fit between the positioning component 6 and the two threaded shafts 5, the positioning component 6 is further optimized. The positioning component 6 is configured to include a first positioning shaft 61, a protruding shaft 62, and a second positioning shaft 63. The protruding shaft 62 is located in the middle of the connection between the first positioning shaft 61 and the second positioning shaft 63. The first positioning shaft 61 and the second positioning shaft 63 are horizontally arranged to ensure that the two ends are at the same height when in contact with the two threaded rods 51, which promotes the stable operation of subsequent clamping. The middle part of the protruding shaft 62 protrudes outward towards the side away from the connecting top shaft 2, forming an inverted V shape. This shape design increases the multi-directional restriction on the workpiece and prevents the workpiece from shifting.

[0053] Furthermore, a locking groove 64 is provided on both the first positioning shaft 61 and the second positioning shaft 63. The two locking grooves 64 are arranged in a cross orientation. This design allows one locking groove 64 to be engaged with a threaded rod 51, and then rotation can be used to engage the other locking groove 64 with another threaded rod 51. At this time, the positioning member 6 will be stably connected with the two threaded rods 51. When the positioning member 6 is moved left, right, forward, or backward, the positioning member 6 will be stably positioned on the connecting top shaft 2.

[0054] Specifically, the slot 64 is U-shaped, and the orientation of the openings in the two sets of slots 64 is different (see reference). Figure 5 While both are the same size, they are all adapted to the threaded rod 51. The diameter of the screw top 52 is set to be larger than that of the threaded rod 51 and larger than that of the locking groove 64. Therefore, when the threaded rod 51 is moved downward by the rotation of the thread, the screw top 52 will press against the positioning part 6 and move downward synchronously until the positioning part 6 presses against the workpiece. At this time, the stabilization work on the upper and lower sides is completed, and the positioning part 6 is positioned in the front, back, left and right directions by the threaded rod 51. At this time, the positioning part 6 will be completely fixed on the upper side of the connecting top shaft 2 to clamp the workpiece and will not move in any direction again.

[0055] The positioning element 6 does not have a direct threaded connection with the threaded shaft 5, which avoids the rotational docking problem that may occur in threaded connections, reduces the difficulty of use, and is particularly suitable for scenarios where workpieces are frequently changed or fixtures are adjusted. Therefore, it is more convenient to replace the positioning element 6 with other connecting elements in different scenarios.

[0056] In this invention, the working steps of the device are as follows:

[0057] 1. First, install the support base 1 on the outer slide rail, adjust its position and fix it with clamping screws 12. When supporting a working object, there are at least two support bases 1 installed on the outer slide rail.

[0058] 2. Next, the side of the connecting top shaft 2 with the trapezoidal groove 4 is installed and fixed to the support base 1 with bolts. Then, the workpiece is placed into the V-groove 3 of the connecting top shaft 2.

[0059] 3. Then, thread the two threaded shafts 5 onto the connecting top shaft 2, and snap the positioning piece 6 onto one of the threaded shafts 5. By rotating, snap the other end of the positioning piece 6 onto the other threaded shaft 5. At this time, the positioning piece 6 can be positioned on the threaded shaft 5 without any loosening in the left, right or front and back.

[0060] 4. Finally, by moving the threaded shaft 5 downwards, the positioning part 6 is fastened and put into contact with the workpiece.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
